DETAILED DESCRIPTION

Reference will now be made in detail to representative examples illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the examples to one preferred example. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.

Conventional drinkware faces several challenges related to leak prevention, lid storage, and thermal insulation. Existing solutions often address one of these issues at a time, forcing users to choose between leak-proof lids and sippable lids, and providing limited insulation approaches. For example, conventional leak-proof lids often lack a convenient sipping option, while sippable lids often fail to prevent leaks during transport. Furthermore, available insulated vessels typically rely on a single insulation mechanism, such as double-walled vacuum insulation, without addressing heat transfer through the top or bottom of the vessel. Lid storage also remains a persistent problem, as lids that are permanently attached to the vessel can interfere with the user's drinking experience, while removable lids can be easily lost or contaminated.

The present disclosure provides a vessel with a dual-lid system that can address these challenges. The vessel can include an inner lid and an outer lid, where the outer lid can interlock with the inner lid to seal the internal storage cavity, providing a leak-proof closure. The outer lid can be selectively removed from the inner lid and stored in a base aperture at the bottom of the vessel when not in use. This configuration can provide both leak-proof sealing and convenient lid storage without the drawbacks of conventional approaches.

In various examples, the vessel can provide 3-way insulation through three distinct mechanisms. The vessel can include an insulated body, such as a double-walled construction, that can reduce heat transfer through the sides and bottom of the vessel. The vessel can include a base portion with walls defining a recessed cavity that can space the vessel from resting surfaces, reducing heat transfer through the bottom of the vessel via conduction. The lid assembly, including the inner lid and the outer lid, can seal openings in the inner lid to reduce heat transfer through the top of the vessel. The vessel can be constructed from various materials, such as stainless steel, titanium, aluminum, or glass, and can have various body shapes, such as a barrel shape, a tapered shape, a pint glass shape, or a flat glass shape.

These and other examples are discussed below with reference to FIGS. 1A through 15B. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. Furthermore, as used herein, a system, a method, an article, a component, a feature, or a sub-feature including at least one of a first option, a second option, or a third option should be understood as referring to a system, a method, an article, a component, a feature, or a sub-feature that can include one of each listed option (e.g., only one of the first option, only one of the second option, or only one of the third option), multiple of a single listed option (e.g., two or more of the first option), two options simultaneously (e.g., one of the first option and one of the second option), or combination thereof (e.g., two of the first option and one of the second option).

Referring initially to FIG. 1A, a perspective view of a leak-proof vessel for storing fluid in accordance with an embodiment of the present disclosure. Further, referring initially to FIG. 1B, a sectional view of a leak-proof vessel for storing fluid in accordance with an embodiment of the present disclosure. For the sake of brevity, FIG. 1A and FIG. 1B have been explained together.

FIG. 1A and FIG. 1B are perspective and sectional views of the leak-proof vessel for storing fluid in accordance with an embodiment of the present disclosure. According to FIG. 1A and FIG. 1B, the leak-proof vessel 100 for storing fluid such as water, juice, tea, coffee and the like, and includes a substantially cylindrical body 102 which acts as a container for storing a fluid. The cylindrical body 102 includes a neck portion 104 which is an elevated and narrower section of the cylindrical body 102. Further an inner lid 106 is assembled over the neck portion 104. For further sealing and to create a leak-proof closure, an outer lid 108 is locked into the inner lid 106. Additionally, a base aperture 110 is formed on a bottom portion of the cylindrical body 102 for holding the outer lid 108 and allowing the user to enjoy a hands-free experience, while preventing any damage to the bottom portion of the leak-proof vessel 100.

The base aperture 110 may be defined by walls 112 extending from the bottom portion of the cylindrical body 102. The walls 112 may define a recessed cavity configured to space the body from a resting surface, thereby reducing heat transfer through the bottom of the vessel via conduction. A coating 114 may be disposed along inner and bottom surfaces of the walls 112. The coating 114 may provide insulation and may further space the walls 112 apart from a resting surface. The coating 114 may be constructed from a soft material configured to protect the body and the surface on which the vessel is placed. In some examples, the coating 114 may include silicone, rubber, thermoplastic elastomer, or other resilient materials. As shown in FIG. 1B, the walls 112 and the coating 114 are visible at the bottom portion of the cylindrical body 102 without the outer lid nested in the base aperture 110. The coating 114 disposed along the bottom surfaces of the walls 112 may contact the resting surface when the vessel is placed thereon, spacing the walls 112 and the body from the resting surface.

The leak-proof vessel 100 may have a height ranging from about 160 mm to about 170 mm. The leak-proof vessel 100 may have a height ranging from about 100 mm to about 300 mm, from about 150 mm to about 270 mm, or the like. The leak-proof vessel 100 can have a common volume, such as about 12 oz, about 16 oz, about 20 oz, about 26 oz, about 32 oz, about 36 oz, about 40 oz, or any other suitable size. Various modifications can be made to the leak-proof vessel 100 to provide different storage capacities, abilities to interface with cupholders, and the like. For example, the body may be tapered or contoured to fit within standard cupholders, may be widened or narrowed to provide relevant shapes for specific beverage types, or may be otherwise shaped to more broadly meet consumer demands. Details on the cylindrical body, neck portion, inner lid, outer lid, base aperture have been elaborated in subsequent paragraphs of the present description.

The cylindrical body 102 is utilized for storing fluid for drinking and may be insulated to maintain a temperature of the contained fluid. The cylindrical body 102 allows the user to engage in outdoor activities, travel and allows the user to enjoy the beverage at the desired temperature while on the go. In addition to this, the cylindrical body 102 allows for efficient storage and provides a comfortable grip for the user. The cylindrical body 102 allows for better insulation throughout the leak-proof vessel 100, reducing heat transfer between an inner and an outer surface of the cylindrical body 102. As a result, the cylindrical body 102 minimizes condensation on the outer surface when the user holds the leak-proof vessel stored with cold fluid and prevents excessive heat transfer to the exterior when handling hot fluid, reducing the risk of discomfort and potential accidents.

According to an alternative embodiment, the cylindrical body 102 may have a double construction wall i.e., an inner wall and an outer wall which are separated by a vacuum or insulating material, creating a barrier that inhibits a heat exchange between the fluid stored and the external environment. Due to the double construction wall, a risk of external condensation is reduced, ensuring that the surface remains dry and free from moisture, especially when the leak-proof vessel is placed on delicate surfaces or within bags or backpacks, as the double construction wall prevents potential damage to belongings caused by fluid seepage.

In various embodiments, the body of the leak-proof vessel 100 may have shapes other than cylindrical. For example, the body may have a barrel shape, with the diameter of the body greater in the center than on the ends. In further examples, the body may have a tapered shape, a pint glass shape, or a flat glass shape. Different body shapes may provide different uses, such as increased storability in bags or apparatuses such as cupholders. In some embodiments, the body may include a shoulder portion having a mason jar bevel or angled shoulder profile. The mason jar bevel may provide a distinctive aesthetic and may facilitate gripping the vessel.

The body may be constructed with one or more materials. In some examples, the body may be constructed with at least one metal, such as stainless steel, titanium, or aluminum, or any combination or alloy thereof. In one or all examples, the body may be constructed with glass. The body may further include a coating or wrap disposed on the surface area of the body. The coating may include silicone, ceramic, rubber, polymer, or any combinations thereof. The coating may provide additional insulation to the vessel and may add softness and texture to the surface of the body, thus increasing grip and preventing against scratches, dents, and similar surface damage. The coating may enclose the entire surface area of the body or may extend around a portion of the body, such as a bottom portion.

FIG. 2 is a top view of the leak-proof vessel 100 for storing fluid is disclosed in accordance with embodiment of the present disclosure. According to FIG. 2, the leak-proof vessel 100 includes a cylindrical body 102 for storing fluid which includes a neck portion 104. The neck portion 104 is a narrower and more elevated portion of the cylindrical body 102, positioned at top to facilitate easy pouring and controlled dispensing of the stored fluids, which allows users to have a precise and mess-free pouring experience, making the leak-proof vessel 100 highly convenient for both everyday use and outdoor activities.

The elevated portion of the neck may have a height ranging from about 4 mm to about 5 mm, from about 2 mm to about 10 mm, or any other suitable height. The neck portion may be taller or shorter depending on the desired vessel size, lid configuration, or pouring characteristics. The elevated portion allows for a comfortable and precise grip while holding the vessel, making it easy for users to control the flow of fluid during pouring or drinking.

Additionally, the neck portion 104 includes a threaded interior surface 202 that enables seamless sealing with a threaded exterior surface of an inner lid (shown in FIG. 4). The threaded interior surface 202 includes a series of helical ridges, forming a spiral pattern inside the neck portion 104, which match and interlock with the threaded exterior surface of the corresponding inner lid. When the inner lid is placed onto the neck portion 104, threaded interior surface 202 creates a tight and secure seal through a threading mechanism which ensures that the inner lid is firmly attached to the neck portion of the vessel, leaving no gaps or openings that may lead to leakage or accidental spills.

Additionally, the threaded sealing mechanism offers convenience and ease of use and allows for quick and effortless opening and closing of the vessel, enabling the user to access the stored fluid with minimal effort. The threaded interior surface ensures that the inner lid remains in place during transportation, eliminating any potential leakage even when the leak-proof vessel 100 is placed in bags, backpacks, or other containers.

FIG. 3A and FIG. 3B are perspective views of the inner lid positioned over the neck portion of the leak-proof vessel for storing fluid in accordance with an embodiment of the present disclosure. According to FIG. 3A and FIG. 3B, the inner lid 106 includes a disk plate 300 with an orifice 302, a lip portion 304 and an air vent 306. One or more grooves 308 are formed on an interior surface 310 of the inner lid 106. The orifice 302 is a crafted opening in the disk plate 300, positioned to facilitate controlled pouring or drinking from the cylindrical body. The orifice 302 allows users to pour liquids out of the cylindrical body with precision, ensuring smooth and mess-free dispensing. Moreover, the orifice 302 enables easy access for sipping directly from the cylindrical body, enhancing user convenience. The inner lid 106 may have a height ranging from about 22 mm to about 26 mm. The one or more grooves 308 may be spaced at an equidistance ranging from about 20 mm to about 22 mm from each other on the interior surface 310 of the inner lid 106 as depicted in FIG. 3C.

The one or more grooves 308 may have a helical orientation along the circular interior surface 310 of the inner lid 106, following a diagonal path around a portion of the circumference of the inner lid 106. This helical orientation may be configured to urge the outer lid toward the inner lid when the outer lid is rotated. The grooves 308 may include a retention feature 312, such as a bump or detent, configured to retain the locking elements 502 on the exterior surface of the outer lid 108 when the outer lid is interlocked with the inner lid. As shown in FIG. 3B, the retention feature 312 may be disposed along the groove 308 at a position configured to engage the locking element 502 when the outer lid is fully rotated into the interlocked position. When the locking elements 502 on the exterior surface of the outer lid 108 interlock with the grooves 308 on the interior surface 310 of the inner lid 106, the outer lid 108 seals the orifice 302 and the air vent 306, thereby creating a leak-proof closure for the internal storage cavity.

Further to ensure optimal functionality, the inner lid 106 also incorporates the air vent 306. The air vent 306 acts as a vital component in regulating pressure inside the cylindrical body when pouring or consuming the fluid, which prevents any vacuum from forming within the vessel during pouring, thereby ensuring an effortless way to dispense the fluid smoothly without any resistance. The presence of the air vent 306 also facilitates a controlled flow of fluid, reducing the risk of splashing or spilling when pouring or drinking.

Furthermore, the interior surface 310 of the inner lid 106 is configured with one or more grooves 308. The one or more grooves 308 are formed in locations to enhance the performance of the inner lid 106. When the inner lid 106 is firmly placed onto the neck portion 104, the one or more grooves 308 create a secure and reliable connection. The one or more grooves 308 are configured to interlock with the one or more locking elements 502 on the exterior surface of the outer lid 108, ensuring a snug fit and effectively preventing any accidental loosening of the outer lid from the inner lid 106.

In addition to this, the one or more grooves 308 provide an extra layer of protection against potential spills or leaks and maintains the integrity of the vessel during the transport or when the vessel is positioned in various different orientations. The combination of the disk plate 300, the orifice 302, and the air vent 306 along with one or more grooves 308 results in a highly functional and reliable inner lid 106.

The outer surface of the inner lid 106 may include a textured pattern, such as a wave pattern, scalloped pattern, dimple pattern, raised dot pattern, knurling pattern, or other textured pattern, configured to provide grip for a user when removing the inner lid 106 from the body. As shown in FIG. 3A, the textured pattern may be disposed on a portion of the inner lid 106 opposite the orifice 302. In other examples, the textured pattern may extend around the entirety of the circumference of the inner lid 106. In some examples, the textured portion may protrude from the rest of the diameter of the inner lid 106, such that the textured portion has a greater diameter than adjacent portions of the inner lid 106, facilitating rotation and removal of the inner lid 106 from the body.

FIG. 4 is a perspective view of the inner lid in accordance with an embodiment of the present disclosure. The inner lid 106 includes a threaded exterior surface 402 that may be made of a plastic material, more specifically, TRITAN plastic, which is a high-quality and durable material. The TRITAN plastic is a type of copolyester material having features including high clarity, impact resistance, and resistance to odors and stains. The TRITAN plastic is also BPA-free, ensuring that the fluid stored inside the cylindrical body 102 remains free from any potentially harmful substances.

In various embodiments, the inner lid may be constructed with one or more different materials. For example, the inner lid may be constructed with polypropylene, thermoplastic elastomer, or TRITAN, or any combination thereof. The use of these materials in the construction of the inner lid may increase the durability, longevity, and overall quality of the vessel.

FIG. 5A and FIG. 5B illustrate a bottom view and a side view, respectively, of an outer lid in accordance with an embodiment of the present disclosure. The outer lid 108 includes one or more locking elements 502 secured on an exterior surface of the outer lid 108. The one or more locking elements 502 interlock with the one or more grooves 308 on the interior surface of the inner lid 106 to firmly engage the inner lid with the outer lid 108.

Further, the outer lid 108 has a pivotal role in sealing the vessel, thereby preventing any unwanted leaks or spills. The outer lid 108 is precisely manufactured to match one or more dimensions of the cylindrical body 102 for fitting snugly over the opening and creating a reliable barrier to keep the fluid safely contained within. The outer lid may be circular in shape which complements the overall aesthetics of the cylindrical body and facilitates effortless alignment and attachment to the cylindrical body. The tactile grip portions 504 may include one or more of a wave pattern, scalloped pattern, dimple pattern, raised dot pattern, knurling pattern, or another textured pattern to provide an enhanced and comfortable grip for the user.

For example, the vessel may include a painted or engraved design on a fastener, screw, or other hardware component of the vessel.

FIG. 5C is a perspective view of the outer lid attached with the inner lid in accordance with an embodiment of the present disclosure. The one or more locking elements 502 on the exterior surface of the outer lid 108 interlock with the one or more grooves 308 on the interior surface of the inner lid 106, creating a tight and secure engagement between the outer lid 108 and inner lid 106. This interlocking causes the outer lid 108 to seal the orifice 302 and the air vent 306 in the inner lid 106, thereby sealing the internal storage cavity. This provides an ease of attaching and detaching the inner lid 106 from the outer lid 108, resulting in enhanced user-friendliness of the leak-proof vessel.

FIG. 5D is a perspective view of an outer lid in accordance with an embodiment of the present disclosure. The one or more locking elements 502 interlock with the one or more grooves 308 to firmly engage the inner lid 106 with the outer lid 108, accompanied by a mechanical click sound, indicating a successful and secure closure. The one or more locking elements 502 may be secured at an angle ranging from about 2.5 degrees to about 3 degrees away from a diameter of the outer lid 108.

In some embodiments, the locking elements 502 may have various configurations. For example, the locking elements 502 may follow a single helical path, a double helical path, or other curved or angled paths along the exterior surface of the outer lid 108. A double helical configuration may provide increased retention strength between the outer lid and the inner lid. The locking elements 502 may be constructed from various materials, such as polypropylene or Tritan. In some examples, the locking elements 502 may be constructed from Tritan to provide increased structural rigidity and pressure resistance compared to polypropylene.

In some embodiments, the one or more grooves 308 may have a helical orientation, following a diagonal path along the circular interior surface of the inner lid, configured to urge the outer lid toward the inner lid when the outer lid is rotated. The grooves 308 may include a retention feature, such as a bump or detent, configured to retain the locking elements 502 when the outer lid is interlocked with the inner lid. In some examples, both the inner lid and the outer lid may comprise TRITAN material, providing TRITAN-on-TRITAN construction for lug strengthening and overall pressure resistance.

FIG. 6 is a perspective view of inner lid and outer lid in accordance with an embodiment of the present disclosure. The outer lid 108 may be made of metal. The inner lid 106 includes a threaded exterior surface which may be made of a plastic material, more specifically, TRITAN plastic, which is a high-quality and durable material. The TRITAN plastic is a type of copolyester material having features including high clarity, impact resistance, and resistance to odors and stains.

In various embodiments, the outer lid may be constructed with one or more different materials. For example, the outer lid may be constructed with polypropylene, thermoplastic elastomer, or TRITAN, or any combination thereof. In one or all examples, the outer lid may be primarily constructed of steel, aluminum, or titanium. The outer lid may further include a lid coating, such as a wrap, film, or glaze disposed on the surface area of the outer lid. The lid coating may include at least one of silicone or steel. The lid coating may provide additional insulation and may add softness and texture to the surface of the outer lid, thus increasing grip and preventing against scratches, dents, and similar surface damage. The lid coating may also provide grip for removal of the outer lid from the inner lid or from the base aperture.

In various embodiments, the outer lid 108 can seal the internal storage cavity in one or more ways. For example, the outer lid 108 can seal the orifice 302 and the air vent 306 individually when interlocked with the inner lid 106. In other examples, the outer lid 108 can form a seal around an inner circumference of the inner lid 106, thereby sealing the orifice 302 and the air vent 306 simultaneously. In further examples, the outer lid 108 can otherwise seal the inner lid 106 and the internal storage cavity through contact between the outer lid 108 and the inner lid 106.

FIG. 7A is a sectional view of the base aperture and FIG. 7B is a bottom view showing the outer lid nested in the base aperture, in accordance with an embodiment of the present disclosure. According to FIG. 7A and FIG. 7B, the base aperture 110 is formed on a bottom portion of the cylindrical body which accommodates the magnetic element 702 that securely holds the outer lid 108 within the base aperture 110, for providing a hands-free experience to a user and protecting the bottom portion of the cylindrical body and the outer lid 108 from damage, loss and potential exposure to one or more undesirable substances like dirt and other contaminants. The base aperture 110 may have a depth ranging from about 17 mm to about 20 mm, from about 15 mm to about 25 mm, or the like. The walls 112 of the base aperture 110 may include the coating 114 disposed along inner and bottom surfaces thereof, as described above with respect to FIG. 1B. The coating 114 may provide additional spacing between the walls 112 and the resting surface when the vessel is placed thereon.

In some embodiments, the base aperture may include a mechanical locking system instead of or in addition to the magnetic element. The mechanical locking system may be configured to lock the outer lid in place when it is stored in the base aperture. The mechanical locking system may provide a stronger method for retaining the outer lid in the base aperture. In embodiments where both a magnetic locking system and a mechanical locking system are used, the systems may operate sequentially. For example, a user may first place the outer lid within the base aperture, thus actuating the magnetic locking system, and then later actuate the mechanical locking system, therefore further locking the outer lid in the stored position.

In some embodiments, the base aperture may be configured to receive accessories in addition to the outer lid. For example, the base aperture may receive a secondary vessel, a storage container, or other accessories that couple to the base aperture via the magnetic locking system, the mechanical locking system, or a combination thereof.

In some examples, the mechanical locking system may include multi-directional or multi-step manual actuation. For example, the mechanical locking system may be a twist-lock mechanism, where a user inserts the outer lid into the base aperture and twists the outer lid so that the locking elements lock into grooves formed in the base aperture. In this manner, the mechanical locking system disposed within the base aperture may mirror the mechanical locking system between the inner lid and the outer lid. Other examples of multi-directional or multi-step manually actuated locking implementations may include threaded systems, quarter-twist thread locking systems, latches, and squeeze-to-release fasteners.

In further examples, the mechanical locking system may include single direction or single-step manual actuation locking implementations. For example, the mechanical locking system may include a detent system or a spring-loaded mechanism. Detents may be disposed on either the outer lid or the inside of the base aperture to retain the outer lid in a stored position. These detents may be fixed or may be spring-loaded such that a user may simply pop the outer lid into the base aperture. Other examples of single direction or single-step manual actuation mechanical locking systems may include snap caps, button release mechanisms, and similar mechanisms.

In some embodiments, the outer lid may include an outer disk portion having a diameter greater than an insertion portion of the outer lid that is inserted into the base aperture. The outer disk portion may cover the base aperture when the outer lid is stored therein. In at least one example, the outer disk portion may protrude past a diameter of the body when the outer lid is inserted into the base aperture, acting as a baseplate for the vessel when resting on a surface, thus increasing stability. In another example, the outer disk portion may be substantially flush with the body when the outer lid is inserted into the base aperture, reducing snagging when moving or packing the vessel. In further examples, the outer disk portion may be recessed from the diameter of the body when the outer lid is inserted into the base aperture, further mitigating snagging and reducing the weight of the vessel. In some embodiments, the outer lid may include an insertion portion without a separate outer disk portion. In such examples, the insertion portion may be configured to fit entirely within the base aperture such that the outer lid does not protrude from or extend beyond the base aperture when stored therein.

FIG. 8 is an exploded view of the inner lid with first gasket in accordance with an embodiment of the present disclosure. A first gasket 800 is configured to fill a space between the threaded interior surface of the neck portion and the threaded exterior surface of the inner lid 106. FIG. 9 is a perspective view of the outer lid with second gasket in accordance with an embodiment of the present disclosure. A second gasket 900 is configured to fill a space between the interior surface of the inner lid and the exterior surface of the outer lid 108.

The first gasket 800 is configured to fill the space between the threaded interior surface of the neck portion and the threaded exterior surface of the inner lid 106. The first gasket 800 may be made from a flexible material that effectively seals any gaps or irregularities between the two threaded surfaces. When the inner lid 106 is firmly attached to the neck portion of the cylindrical body, the first gasket 800 creates a watertight seal, preventing the fluid from escaping or seeping.

In addition, a second gasket 900 is configured to fill the space between the interior surface of the inner lid and the exterior surface of the outer lid 108. The second gasket 900 acts as an additional layer of protection, ensuring a secure and airtight seal between the two lids. When the outer lid 108 is firmly engaged with the inner lid 106, the second gasket 900 forms a tight barrier that reinforces the leak-proof properties of the cylindrical body. The double gasket arrangement including the first gasket 800 and the second gasket 900 provides enhanced leak prevention.

In addition to this, the selection of high-quality materials for both gaskets ensures the durability and resilience over time. The first gasket 800 and the second gasket 900 are structured to withstand repeated use and maintain the sealing effectiveness even with frequent lid application and removal. The ability to endure a wide range of temperatures, from scalding hot to freezing cold, further enhances the leak-proof performance in various conditions.

Furthermore, the flexible nature of the gasket allows for easy cleaning and maintenance, ensuring that the user keeps the cylindrical body 102 hygienic and pristine with minimal effort. Regular cleaning of the first and second gaskets helps maintain the sealing capabilities, ensuring that the leak-proof vessel continues to deliver a leak-proof experience with each use.

In accordance with various embodiments, the outer lid may be removably and selectively coupleable to the inner lid or the base aperture. When coupled to the inner lid, the outer lid may seal the orifice 302 and the air vent 306, providing a leak-proof closure for sipping or transporting the vessel. When the outer lid is removed from the inner lid, the outer lid may be stored in the base aperture, freeing the user's hands and protecting the outer lid from damage or contamination. This selective coupling provides a dual-use configuration in which the outer lid serves as both a sealing lid and a storable component.

In some embodiments, the lid system may be compatible across multiple vessel sizes within a product line. For example, the inner lid and the outer lid may be configured to couple with vessels of different volumes, such as 12 oz, 16 oz, 20 oz, 26 oz, 32 oz, 36 oz, 40 oz, or any other suitable size, without requiring a different lid for each vessel size.

In accordance with various embodiments, the vessel may provide thermal insulation through three distinct mechanisms, referred to herein as 3-way insulation. The three mechanisms may include insulation through the sides of the vessel, insulation through the bottom of the vessel, and insulation through the top of the vessel. Each mechanism may operate independently or in combination with the other mechanisms to provide enhanced thermal performance.

The first mechanism of insulation may be provided by the insulated body of the vessel. As described above, the body may include a double-walled construction with a vacuum insulation layer between an inner wall and an outer wall. The double-walled construction may reduce heat transfer through the sides of the vessel and a bottom of the vessel, maintaining the temperature of the stored fluid. In other examples, the body may include other insulating materials or constructions, such as foam insulation or aerogel insulation, disposed between the inner wall and the outer wall.

The second mechanism of insulation may be provided by the base portion of the vessel. The base portion may include walls 112 defining a recessed cavity, such as the base aperture 110. A coating 114 may be disposed along inner and bottom surfaces of the walls 112 to provide additional insulation and to further space the walls 112 from the resting surface. The walls of the recessed cavity may be configured to space the body from a resting surface, thereby reducing heat transfer through the bottom of the vessel via conduction. This spacing may be particularly beneficial for cold beverages, as it prevents heat from the resting surface from conducting through the bottom of the vessel and warming the stored fluid. When the outer lid is stored in the recessed cavity, the outer lid may further space the walls from the resting surface, providing additional separation between the vessel and the resting surface.

The third mechanism of insulation may be provided by the lid assembly. The inner lid may define a first opening, such as the orifice 302, and a second opening, such as the air vent 306. The outer lid may be configured to seal both the first opening and the second opening when interlocked with the inner lid, thereby reducing heat transfer through the top of the vessel. This sealing may be particularly beneficial for hot beverages, as it prevents heat from rising and escaping through the top of the vessel. The combination of the inner lid and the outer lid may form an insulating barrier at the top of the vessel.

The combination of the three mechanisms—insulation through the sides via the double-walled body, insulation through the bottom via the recessed cavity spacing the vessel from resting surfaces, and insulation through the top via the lid assembly sealing the openings—may provide superior thermal performance compared to vessels that rely on one or two of these mechanisms.

FIG. 10 is a perspective view of the body 1002 of the vessel 1000, in accordance with one or more embodiments of the present disclosure. In at least one example, the body 1002 can be cylindrical in shape or any other shape conducive to storing fluid. For example, and as shown in FIG. 10, the body 1002 can have a barrel shape, with the diameter of the body 1002 greater in the center than on the ends. In further examples, the body 1002 can have a tapered shape, a pint glass shape, or a flat glass shape. In some examples, different body shapes can provide different uses, such as increased storability in bags or apparatuses such as cupholders.

In one or more examples, the body 1002 can be constructed with one or more materials. In some examples, the body 1002 can be constructed with at least one metal. For example, the body 1002 can be constructed with stainless steel, titanium, or aluminum. Additionally, the body 1002 can be constructed with any combination or alloy of stainless steel, titanium, and aluminum thereof. In one or more examples, the body 1002 can be constructed with glass.

Furthermore, the body 1002 can include a coating 1012. In some examples, the coating 1012 can be a wrap, film, or glaze disposed on the surface area of the body 1002. In at least one example, the coating 1012 can include silicone, ceramic, rubber, polymer, or any combinations thereof. In some examples, the coating 1012 can provide additional insulation to the vessel 1000. The coating 1012 can also add softness and texture to the surface of the body 1002, thus increasing grip and further preventing against scratches, dents, and similar surface damage.

In one or more examples of the present disclosure, the coating 1012 can enclose the entire surface area of the body 1002. In other examples, as shown in FIG. 10, the coating 1012 can extend around a portion of the body 1002. In some examples, the coating 1012 can extend around a bottom portion of the body 1002. This can provide additional insulation and protection to the vessel 1000 when setting the vessel 1000 on surfaces with varying textures and temperatures.

FIG. 11 shows a perspective view of the vessel 1100 with the inner lid 1106 and the outer lid 1108, in accordance with one or more embodiments of the present disclosure. In some examples, the inner lid 1106 can be constructed with one or more different materials. In some examples, the inner lid 1106 can be constructed with polypropylene, thermoplastic elastomer, or TRITAN. In other examples, the inner lid 1106 can be constructed with one or more of any combination of polypropylene, thermoplastic elastomer, or TRITAN. Likewise, the outer lid 1108 can be constructed with one or more different materials. In some examples, the outer lid 1108 can be constructed with polypropylene, thermoplastic elastomer, or TRITAN. In other examples, the outer lid 1108 can be constructed with one or more of any combination of polypropylene, thermoplastic elastomer, or TRITAN. In one or all examples, the outer lid 1108 can be primarily constructed of steel, aluminum, or titanium. The use of these materials, or the combination thereof in the construction of the inner lid 1106 and the outer lid 1108 can increase the durability, longevity, and overall quality of the vessel 1100.

In some examples, the outer lid 1108 can include a lid coating 1114. In some examples, the lid coating 1114 can be a wrap, film, or glaze disposed on the surface area of the outer lid 1108. In at least one example, the lid coating 1114 can include at least one of silicone or steel. For example, the lid coating 1114 can include a silicone layer around the outer lid 1108, a steel layer or casing around the outer lid 1108, or any combination of both silicone and steel layers surrounding the outer lid 1108. In some examples, the lid coating 1114 can provide additional insulation to the vessel 1100. The lid coating 1114 can also add softness and texture to the surface of the outer lid 1108, thus increasing grip and further preventing against scratches, dents, and similar surface damage.

In one or more examples of the present disclosure, the lid coating 1114 can extend around at least a portion of the inner lid 1106. This can provide additional insulation and protection to the inner lid 1106 when handling, moving, or otherwise using the inner lid 1106 and outer lid 1108.

FIG. 12 illustrates a perspective view of the base aperture 1210 and an exemplary mechanical locking system, in accordance with one or more embodiments of the present disclosure. In some examples, the base aperture 1210 of the vessel 1200 can include a magnetic locking system as shown above in FIG. 4. Instead of a magnetic locking system, the base aperture 1210 of the vessel 1200 can include a mechanical locking system 1216. In some examples, the mechanical locking system 1216 can be configured to lock the lid in place when it is stored in the base aperture 1210. The mechanical locking system 1216 can be beneficial in that it can provide a stronger method for retaining the lid in the base aperture 1210. In other examples, the base aperture 1210 can include a combination of both a mechanical locking system 1216 and a magnetic locking system to retain the lid when it is stored in the base aperture 1210. Furthermore, in embodiments where both a magnetic locking system and a mechanical locking system 1216 are used, the systems can operate sequentially. For example, a user can first place the lid within the base aperture 1210, thus actuating the magnetic locking system, and then later actuate the mechanical locking system 1216, therefore further locking the lid in the stored position.

In one or more examples of the present disclosure, the mechanical locking system 1216 can include multi-directional or multi-step manual actuation. As shown in FIG. 12, the mechanical locking system 1216 can be a twist-lock mechanism. In some examples, a user can insert the lid into the base aperture and twist the lid so that the locking elements (502 in FIG. 3B) lock into the base grooves 1208, similar to as shown above in respect to the inner lid locking to the outer lid in FIG. 3C. In this manner, the mechanical locking system 1216 disposed within the base aperture 1210 can mirror the mechanical locking system between the inner lid and the outer lid.

In some examples, the mechanical locking system 1216 can include other multi-directional or multi-step manually actuated locking implementations. For example, the mechanical locking system 1216 can include threaded systems, such that a user can thread the lid into the base aperture 1210. In this threaded system example, the threads can be continuous or can be configured to form a quarter-twist thread locking system. Other examples of multi-directional or multi-step manually actuated locking implementations can include, but are not limited to, latches, squeeze-to-release fasteners, and similar implementations.

In further examples, the mechanical locking system 1216 can include single direction or single-step manual actuation locking implementations. For example, the mechanical locking system 1216 can include implementations such as a detent system or a spring-loaded mechanism. In these examples, detents can be disposed on either the lid or the inside of the base aperture 1210 to retain the lid in a stored position. In some examples, these detents can be fixed or can be spring-loaded such that a user can simply pop the lid into the base aperture 1210. Other examples of single direction or single-step manual actuation mechanical locking systems can include, but are not limited to, snap caps, button release mechanisms, and similar mechanisms.

FIG. 13 illustrates a perspective view of the vessel 1300 with the lid in a stored position, in accordance with one or more embodiments of the present disclosure. In some examples, the outer lid 1308 can include an outer disk portion 1318. In some examples, the outer disk portion 1318 can have a diameter greater than an insertion portion of the lid that is inserted into the base aperture. In this manner, the outer disk portion 1318 can cover the base aperture when the lid is stored therein.

In at least one example, the outer disk portion 1318 can protrude past a diameter of the body 1302 when the lid is inserted into the base aperture. In some examples, this can be beneficial in that the outer disk portion 1318 can act as a baseplate for the vessel 1300 when resting on a surface, thus increasing stability and increasing the force needed to topple the vessel 1300.

In another example of the present disclosure, the outer disk portion 1318 can be substantially flush with the body 1302 when the lid is inserted into the base aperture. In some examples, this can reduce snagging the outer disk portion 1318when moving or packing the vessel 1300 with the lid in the stored position. In further examples, the outer disk portion 1318 can be recessed from the diameter of the body 1302 when the lid is inserted into the base aperture. This embodiment can further mitigate snagging and can reduce the weight of the vessel 1300.

FIG. 14A is an isometric view and FIG. 14B is a perspective view of an inner lid 1400. The inner lid 1400 includes an orifice 1402 for accessing the contents of the vessel. A recess 1404 is disposed adjacent the orifice 1402 to provide drinking comfort. The inner lid 1400 includes one or more grooves 1406 formed on an interior surface of the inner lid 1400 for interfacing with an outer lid. In the example shown, three grooves 1406 are disposed around the perimeter of the interior surface of the inner lid 1400. Each groove 1406 includes a retention feature 1408 configured to engage with a corresponding feature on the outer lid to secure the outer lid to the inner lid 1400. The inner lid 1400 includes threads 1410 on an outer surface thereof for interfacing with the vessel. The inner lid 1400 includes a protrusion 1412 extending from the outer surface of the inner lid 1400. The protrusion 1412 provides the user with leverage for removing the inner lid 1400 from the vessel. The protrusion 1412 includes an aperture 1414 that can be used for a strap, band, leash, or the like for carrying the vessel.

FIG. 15A is an isometric view and FIG. 15B is a perspective view of an outer lid 1500, in accordance with one or more embodiments of the present disclosure. The outer lid 1500 includes locking elements 1502 disposed around an outer perimeter of a protruding portion of the outer lid 1500. In the example shown, three locking elements 1502 are provided, corresponding to the three grooves 1406 on the inner lid 1400. In other examples, the number of locking elements 1502 and grooves 1406 can be more or fewer than three. Each locking element 1502 has a bean-shaped profile and includes a retention recess 1504. The retention recess 1504 interfaces with the retention feature 1408 on the inner lid 1400 to secure the outer lid 1500 to the inner lid 1400. The outer lid 1500 includes a tactile grip portion 1506 to provide an enhanced and comfortable grip for the user.

In the embodiment shown in FIGS. 14A-15B, the inner lid 1400 and the outer lid 1500 form a double helix lid arrangement. The outer lid 1500 twists onto the inner lid 1400 via the locking elements 1502 engaging the grooves 1406, and the inner lid 1400 twists onto the vessel via the threads 1410. This double helix arrangement can provide increased retention strength and pressure resistance compared to a single helix arrangement.

In various embodiments, the inner lid and the outer lid can interface via different methods. For example, the inner lid and the outer lid can interface via a lug-receptor system as described above with respect to the grooves 308 and locking elements 502 or the grooves 1406 and locking elements 1502. In other examples, the inner lid and the outer lid can interface via a continuous thread system, similar to how the inner lid attaches to the vessel via threads 1410. In further examples, the inner lid and the outer lid can interface via protrusions on the outer lid that lock into internal fitted spaces or recesses within the inner lid, rather than interfacing with external features on the inner lid. In yet further examples, the inner lid and the outer lid can interface via a snap-fit system, a press-fit system, a bayonet mount, or other suitable attachment mechanisms. Different interface methods can provide different levels of retention strength, ease of use, and resistance to pressure from carbonated or hot beverages.
