TECHNICAL FIELD

The subject disclosure relates generally to bottles and drinking containers. In particular, the invention relates to a bottle having a hardened, bite proof straw assembly.

BACKGROUND

Conventional bottles with straws are consistently exposed to harsh biting conditions from young children. After a long period of repeated biting, these straws may become weakened or damaged causing irregular flow or loose particles. Children, however, are known for biting through straws, causing tears and breaking the straw. Trying to account for this by stiffening the straw creates an exposed, inflexible opening, resulting in sanitation issues and spills. Unfortunately, these deficiencies have not been solved and have never been addressed previously.

DETAILED DESCRIPTION

Particular embodiments of the present invention will now be described in greater detail with reference to the figures.

FIG. 1 illustrates a bottle 10 having a lid 20, a container 30, a spout 40, a cover 50 and a pivoting connection 60 embodied as a strap 54.

FIG. 2 shows the cover 50 having a cap portion 52 and the strap 54. The cap portion 52 may be co-molded with the strap 54 which is made of a flexible material such that it allows the cap portion to pivot about the pivoting connection 60. The cap portion 52 may also be of a harder durometer than the strap 54 by using methods later discussed herein. However, the strap 54 may also be made from a second material than the cap portion 52. The cap portion 52 and strap 54 can take a variety of different shapes and sizes and be made from a wide variety of suitable materials with various thicknesses and durometer.

In a closed position, the cover 50 will enclose the spout 40 such to prevent exposure of the spout 40. The cap portion 52 has a shape which generally follows the contour of the spout 40 shape to create a slip-fit frictional connection preventing the cover 50 from slipping off of the spout 40 without a predetermined amount of force to overcome the friction fit. This force should be high enough to keep the cover 50 in a closed position if the bottle 10 is knocked over or dropped, but low enough such that a young child or parent can remove the cover 50 from the spout 40 with ease.

The cap portion 52 may also have a beaded edge 57 and a pull tab 58, which gives a user a place to grip onto for increased leverage of the cover 50 and to facilitate removing the cover 50 from the closed position. In addition, the cap portion 52 may connect directly to the lid 20 or base of the spout 40 by a mating feature between the beaded edge 57 and the spout 40 or lid 20. The mating feature may act as a slip-fit or snap fastener, or any other suitable connection to prevent the cover 50 from slipping off of the spout 40.

FIGS. 3-4 illustrate the spout 40 having a top portion 42, a bottom portion 44, a middle band 46 and a lip 48. The spout 40 can be made in various shapes or sizes, and be made from a variety of suitable materials. An opening in the top portion 42 may be made in the form of a circle, oval, race track, or any other suitable shape.

The middle band 46 acts as a bite guard and subsequently protects the spout 40 from biting of the user. The middle band 46 may have a first durometer and the top portion 42 and bottom portion 44 may have a second durometer. The first durometer is greater than the second durometer in order to provide added bite protection. Alternatively, both the top portion 42 and the middle band 46 may have the first durometer while the bottom portion 44 may have the second durometer, thus protecting the entire upper portion of the spout 40 from gnawing or biting.

The middle band 46 may be manufactured to have a first color while the top portion 42 and bottom portion 44 have a second color. This gives the user a visual indicator of where the material durometer changes and thus where the bite guard is located. Furthermore, using different colors for the middle band 46 may act to distinguish spouts with different durometer bite guards. For instance, a pink middle band 46 may represent a durometer of 70 Shore while a turquoise middle band 46 may represent a durometer of 100 Shore.

The middle band 46 may be extended completely flush with the top portion 42 and bottom portion 44, or may bow out by a predetermined width to form a bump 47 to further distinguish it from the rest of the spout 40. The bump 47 may be located at the top, middle or bottom of the middle band 46, or any combination thereof. The middle band 46 may also include various textures, patterns or designs on its surface or interior to further distinguish it from the rest of the spout 40. Differing the texture of the middle band 46 or providing the bump 47 will provide the user an additional tactile feedback of where the durometer changes when they drink from the bottle 10.

In order to form the difference in durometer, the middle band 46 having the first durometer may be compression molded, and then the rest of the spout 40 having the second durometer may be subsequently liquid injection molded around the middle band 46. In an alternative embodiment, both the top portion 42 and middle band 46 may have the first durometer while the bottom portion 44 has the second durometer. This may be manufactured in the same fashion as the previous embodiment. It also may be manufactured by first compression molding the top portion 42 and middle band 46 with the first durometer, then subsequently compression molding the bottom portion 44 with the second durometer.

FIG. 5 depicts the strap 54 having a textured inner surface comprised of raised ridges 54a and grooves 54b. Since the strap 54 has a smaller thickness at grooves 54b, the strap 54 will be more flexible and thus the cover 50 can more easily pivot about the pivoting connection 60. The raised ridges 54a also provide an increased tactile surface for the user to grip when removing the cover 50. The surface of strap 54 may be formed with a variety of patterns, shapes, thicknesses and hardness.

Furthermore, the cap portion 52 may be constructed to have a different durometer from the strap 54 in a similar method as the middle portion 46 as recited above. In the closed position, this would allow for the cap portion 52 to be harder in order to protect the spout 40 while accidentally dropped or knocked over. At the same time, constructing the strap 54 softer would allow the user to more easily manipulate the position of cover 50 from open to closed or vice versa.

FIGS. 6-9 illustrate the bottle 10 further comprising handles 70 which extend out from opposing sides of the lid 20 and curve around towards a lower portion of the container 30. As shown in FIG. 8, the handles 70 may also include a multitude of grooves 72 which enhance the grip of the user. The handles 70 can take a variety of different shapes and sizes and may have different types of grips such as rubber, plastic, groves, notches, apertures, textures, or any other suitable material or device to facilitate gripping by a user.

FIG. 10-13 depict the lid 20, the spout 40, the cover 50, the strap 54 and the pivoting connection 60 in greater detail. FIG. 11 illustrates a cross section of the bottle 10 about section lines A-A in FIG. 10 with the cover 50 in the closed position.

The lid 20 further comprises a ventilation shaft 22, a vent extrusion 22a and a cover attachment mechanism 80. In addition, the cover 50 further comprises a recess 53 in the cap portion 52, and a cover anchor 55 located at a second end of the strap 54, wherein the cap portion 52 is located at a first end of the strap 54. As best shown in FIG. 11, the cover anchor 55 is generally round and comprises an aperture which receives the vent extrusion 22a when the bottle 10 is assembled. However, the cover anchor 55 may take a variety of shapes and sizes suitable to mate and/or attach the cover 50 to the lid 20. This configuration keeps the cover 50 attached to the bottle 10 and allows for the strap 54 to rotate about the pivoting connection 60, while also being removable during washing. Furthermore, the cover anchor 55 may instead be attached or integral to the spout 40.

The spout 40 further comprises a horizontally extending ridge 48 and a ventilation aperture 49. When assembled, the ridge 48 rests between the lid 20 and an upper portion 32 of the container 30 and is fixed in place. The ridge 48 also acts to fix the cover anchor 55 into place between the spout 40 and the lid 20. The ventilation aperture 49 rests against a bottom of the vent extrusion 22a of the lid 20. This allows air to flow from the atmosphere, through the ventilation shaft 22 of the lid 20, the ventilation aperture 49 of the spout 40, and into the container 30.

Since the cover anchor 55 surrounds the ventilation shaft 22, both the pivoting connection 60 and the ventilation shaft 22 can be displaced by a predetermined amount from the spout 40. The ventilation shaft 22 is positioned relative to the spout 40 to permit the free flow of air into the container 30 while in use. In addition, the pivoting connection 60 is suitably positioned relative to the spout 40 so that the cover 50 may not be obstructed by the user from gripping the spout 40 with their mouth while drinking from the container 30. It is to be understood, however, that the ventilation shaft 22 may be located on different parts of the lid 20, container 30 or spout 40 as will be shown in an alternative embodiment described in FIG. 14.

FIGS. 12-13 show the bottle with the strap 54 (in dashed line) and cover anchor 55 hidden. FIG. 13 illustrates a cross section of the bottle 10 about section lines B-B in FIG. 12. As shown, the lid 20 comprises an inner space 25 which surrounds the vent extrusion 22a. The inner space 25 is adapted to receive the cover anchor 55 when assembled and fixes the cover anchor 55 in place between the lid 20 and the spout 40.

The cover attachment mechanism 80 is shown in more detail in FIG. 13. The recess 53 in the cover 50 has a resilient undercut which slightly flexes as it is pushed onto the cover attachment point 23. The recess 53 flexes back into its original configuration when installed into the open position, thereby gripping the cover attachment point 23 of the lid 20 and preventing the cover 50 from flipping back into the closed position or any other position while the user is drinking from the bottle 10. It is to be understood that the cover attachment mechanism 80 can take a variety of forms, including Velcro®, snap, hook and loop, slip-fit, button, or magnets fasteners, or any other suitable coupling mechanism.

FIG. 14 shows a back perspective view of a bite proof bottle 110 with a pivoting cover 150 having another exemplary spout 140 and lid 120 according to the subject disclosure. As shown in FIGS. 14-16, the cover 150 includes a cap portion 152 and a strap 154 which connects to the lid 120 at a pivoting connection 160. The cap portion 152 also includes a recess 153 which receives a complementary cover attachment point 123 on the lid 120. FIGS. 15-16 show another method to attach the cover 153 to the lid 120 which uses an integrated pin 223 connection which fits into an aperture 253 located within the cover 150

FIG. 14 shows the spout 140 comprising a top portion 142, bottom portion 144, middle portion 146 and a vent 145. Here, the strap 154 is attached between the spout 140 and the lid 120 in a separate position away from the vent 145. The vent 145 communicates air from the atmosphere directly into a container 130. The middle portion 146 may be constructed to have similar features of the middle portion 46 as recited above.

FIGS. 17-26 show another briefly mentioned above process in which an upper portion 242 of a soft top insert 200 may be constructed to include the previous mentioned top portion 42 and the middle band 46 of a single material composition defining the spout 240. That is, the spout 240 may be made of a harder first material composition of a first harder durometer (such as in the range of 60), and the second softer lower region 144 may be made of a softer second material composition comprised of a softer durometer (such as in the range of 50).

As will be described in more detail later, the spout 240 may be formed of, and fastened to, the softer lower region 144 of the soft top insert 200 via a compression molding technique and/or any other suitable technique capable of fastening a spout of a first durometer to a lower base portion of a soft top insert which is composed of a different second durometer composition.

FIGS. 21-24 illustrate various exemplary views of the soft top insert 200 including the spout 240 having a single material consistency of a first durometer and a lower region 144 having a single material consistency of a second durometer being softer than the spout 240.

FIGS. 25-26 depict front and side cross section views of the spout soft top insert 200 including the spout 240 connected to the lower region 144. As shown, various contours may be constructed into the region adjacent to the connection between the spout 240 and the lower region 144 for a variety of different purposes. For example, various concentric bumps or ridges can be configured to create a connecting lap-joint between the between the spout 240 and the upper end of the lower region 144. Alternatively, a channel 245 can be constructed adjacent to the spout 240 and the upper end of the lower region 144 in order to provide a flow area to allow for trapped gasses during the compression molding process to escape. A plurality of different configurations is possible at this juncture between the spout 240 and the upper end of the lower region 144.

FIGS. 27-35 illustrate one exemplary process for constructing the soft top insert would be a compression molding process in which the is one tool that uses two different molds. A first mold would be used to construct the spout tip and a second mold may be used for an overmold process to connect the spout tip to the lower portion of the soft top insert.

In a first step as shown in FIG. 27, the spout tip is processed. A first material composition, such as a suitable silicon, is placed between an upper and a lower mold adjacent to a removable insert or core. The first composition is placed over the removable core and adjacent to the various cavities adapted to receive the molten composition to form the various spout tips. By way of example shown in FIG. 27, slabs of 60 durometer silicone may be placed over the removable insert or core. The removable core can be a single piece core or a modular core that is assembled with various component parts. As shown in FIG. 27, the various component parts of the removable core stack adjacent to each other forming the recess structure that will define the shape of the spout between the upper and lower molds.

In the first step process, the removable core is aligned within the upper and lower molds and the various spouts are formed by a first compression molding process in which the molding material, is generally preheated, is placed in the open, heated mold cavity defined by the upper and lower molds and the inner removable core. The mold is closed with a predetermined force, and pressure is applied to force the mold material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured to form the shape of the spouts. Following the spout molding process, the spout may undergo a curing process at a predetermined heat and duration of time.

The advantage of compression molding is its ability to mold fairly intricate parts. It is also one of the lowest cost molding methods. However, it is to be understood that other methods for molding the spout may be employed, such as but not limited to other methods such as transfer molding and injection molding.

In a second step as shown in FIG. 28, the individual spouts are shown attached to the removable core which has been removed from the upper and lower molds. Also shown, the individual spouts may be removed as rows of spouts from the removable core. As shown in FIG. 29, various individual components of the removable core may then modularly separated from each other so that each of the individually molded spout tips may be accessed and removed from the removable internal core. Any extraneous flashing may be cleaned off, or removed from the individual spouts.

FIG. 30 shows another step in which the molds for the first spout mold have been removed and the molds for the second process are put in place in the compression mold tooling. In the second overmold process, the spout mold is over molded with another mold material of a second durometer.

In this step, the overmold has a mold comprised of three layers. As shown in FIG. 31, the molded spout tips are placed upside down onto mating projections on the bottom most lower layer of the mold. In a next step, the middle layer mold is aligned and lowered over the first lower layer holding the molded spout tips. The middle layer includes an internal mold recess adapted to be configured to the outer shape of the soft top insert. When the upper third layer is closed over the second and first layers, an internal shape forming the soft top insert is constructed between the first, middle and upper molds and overmolded or melted onto the preformed spout tip.

Referring back to FIG. 32, a second mold material of a predetermined quantity of a second softer durometer material is placed over the internal mold recess above the middle layer. For example, predetermined quantities of slabs of 50 durometer silicon may be positioned adjacent to various recessed defined in the middle layer of the mold to form the lower portion of the soft top insert.

As shown in FIG. 33, the lower face of the upper mold includes at least one projection defining a negative construction of the internal surface area of the soft top insert. When the upper mold layer is compressed against the second middle layer mold, the projections on the lower face of the upper mold defines the inner construction of the soft top insert. During the compression process, the upper, middle and lower mold layers closed against each other under high pressure and heat defining the configuration of the soft top insert and it being overmolded onto the hardened spout tip. That is, the top mold layer compresses onto the middle mold layer and finally onto the lower mold layer of the mold. This compression forms the bottom portion of the soft top insert and causes the bottom of the spout to overmold onto the spout tip. Thereafter, the complete soft top insert may be processed through a subsequent curing procedure. Since the spout tip of a first durometer has been cured, it is possible to form a clean secure bond connection against the upper connecting surface of the lower region of the soft top insert.

Various techniques may be implemented to create a secure connection between the spout tip and the upper portion of the lower region of the soft top insert below the spout tip, such as by providing a lap-joint or other suitable interlocking structure there-between according to this subject disclosure. Other alignment and position fastening techniques may be employed to ensure that the position of the spout tip adjacent to the lower layer mold will not shift from its axial alignment during the compression process such as by forming ridges or joints to keep the spout in a predetermined position during the compression process. See for example the various ridges and bumps 220 integrated onto the spout as shown in FIGS. 35-26 at the junction adjacent to the spout tip 240 and the lower region 144 of the soft top insert 200.

Likewise, various other processes may be implemented to bond the spout tip of a first durometer to a lower region of a soft top insert. For example, instead of a two step process, both the spout tip of a first durometer and the lower region of the soft top insert may be formed in a single compression process. Furthermore, other manufacturing processes may be employed, including but not limited to for example, a first or second stage compression molding process, an injection molding process, or other suitable process capable of securely bonding a spout tip of a first durometer to a lower region of a soft top insert of a second durometer. Various different suitable durometers may be used according to this subject disclosure.

FIG. 34 shows the positioning of various soft top inserts webbed together after the compression molding process has occurred and the upper layer has been removed from the middle layer mold.

FIG. 35 depicts the various soft top inserts webbed together prior to removal of excess material flashing between adjacent soft top inserts. The complete spouts are removed from the mold and set to cool.

FIGS. 36-42 illustrate another exemplary embodiment of the subject disclosure having a bottle 10 with a bite proof straw 400. As shown, the bottle has a bite proof straw 400, a collar 410, and a flip lid 420 hingedly attached to the collar 410. The collar 410 is attached to the container 30.

The bite proof straw 400 may have a top portion 402 and a bottom portion 406. The straw 400 can be made in various shapes or sizes and can be made from a variety of suitable materials. An opening 403 in the top portion of the straw can be made in the form of a circle, oval, or any other suitable shape.

The top portion 402 of the straw 400 may act as a bite guard and protect the straw 400 from biting by the user. The top portion 402 may be comprised of a first durometer and the bottom portion 406 may be comprised of a second durometer. The first durometer may be greater than the second durometer having a more durable composition to provide added bite protection to the top portion 402, which is bitten by the user. The top portion 402 may be manufactured to have a first color while the bottom portion 406 may have a second color identifying a different hardness, such as shown in FIG. 37. This gives the user a visual indicator of where the material durometer changes and thus were the bite guard is located. Furthermore, different colors may act to distinguish bite guards with different durometer values.

FIG. 37 illustrates an alternative construction for the bite proof straw 400. Alternatively, there may be a middle band portion 404 between the top portion 402 and bottom portion 406 that may act as a bite guard. The middle band portion 404 may have a third durometer that is greater than the durometer of the top portion 402 and bottom portion 406 to give added bite protection. The middle band portion 404 and top portion 402 may alternatively have the first durometer and the bottom portion 406 may have the second durometer. The middle band portion 404 may be manufactured to have a color according to a predetermined durometer value. Furthermore, the top portion 402 and bottom portion 406 may be constructed of a first durometer and the middle band portion 404 may be constructed of a second durometer.

The middle band portion 405 may be extended concentrically flush with the top portion 402 and bottom portion 406, or may extend radially outward by a predetermined thickness to form a bump 405 to further distinguish it from the rest of the straw 400. The bump 405 may be located at the top, middle, or bottom of the middle band portion 404 (as shown in FIG. 37), or any combination thereof. The middle band portion 404 may also include various textures, patterns, or designs on its surface or interior to further distinguish it from the rest of the straw. Differing the texture of the middle band portion 404 or providing the bump 405 will provide the user an additional tactile feedback of where the durometer changes when they drink from the bottle 10.

The bottom portion 406 of the straw 400 can be made with a sufficiently flexible material, allowing the straw 400 to bend without being damaged. The bottom portion 406 may be constructed to endure the cyclic bending and unbending that occurs when switching the straw 400 between the stored and in-use positions.

As shown in FIG. 40, the bottom portion 406 may have a recessed ring 407 that mates with a protruding ring 412 from the collar 410 to removably secure the straw 400 to the collar 410 and create a seal. The bottom portion 406 may have a wider segment 408 that prevents upward displacement of the straw 400 through an opening 413 in the collar 410 as well as reinforce the seal between the straw 400 and the collar 410.

The bottom portion 406 of the straw 400 can also attach to a ventilation shaft 415 of the collar 410 by a friction fit grip. The bottom portion 406 can also cover the ventilation shaft 415 with a one-way passage valve 409, allowing air to enter into the container 30 while preventing the spillage of a fluid contained therein.

In order to form the differences in durometer of the different portions of the bite proof straw 400, the top portion 402 having the first durometer may be compression molded and the bottom portion 406 having the second durometer may be subsequently liquid injection molded around the top portion. Alternatively, the middle band portion 404 may be compression molded alongside the top portion 402, and then the bottom portion 406 may be subsequently molded. The bottom portion 406 may alternatively be compression molded in any of these embodiments.

FIGS. 40-42 depict various cross section views of the bottle 10, with and without, the bite proof straw 400. The top portion 402 may be comolded over a portion of the bottom portion 406 as shown or the top portion 402 may be attached to the bottom portion 406 in a variety of ways previously described.

The collar 410 may be made in a variety of shapes and sizes, and may be made out a variety of materials. The collar 410 may secure the straw 400 by mating with a recessed ring 407 in the straw 400 or by any other suitable mechanism. The collar 410 has a ventilation shaft 415 or opening to allow atmospheric air to enter into the container 30. The collar 410 may also have a protrusion 416 sufficiently large in size and near enough to the straw 400 that the protrusion 416 will constrict the flow of liquid through the straw 400 when the straw 400 is folded over the protrusion 416 in a closed position.

The collar 410 may have a recess 418 or recesses that mate with protrusions 422 on the flip lid 420 in order to attach the flip lid 420 to the collar 410. The collar 410 may also have a locking recess or similar mechanism to reversibly secure the flip lid 420 closed when in a closed position. As shown in FIG. 42, one side of the collar 410 may also have a protruding end 419 with a ledge that meets with the flip lid 420 in order to protect and cover the open end of the straw 400 when the straw 400 is folded over in the closed position.

FIG. 42 shows the flip lid 420 may have protrusions 422 that hingedly attach to the collar 410, allowing the flip lid 420 to alternate between an open position and a closed position. The flip lid 420 has a raised chamber 424 that envelopes the straw 400 in the closed position. The flip lid 420 may have any number of grip elements 425 on the outer surface to assist with moving the flip lid 420. These grip elements 425 may also be on the outer surface of the raised chamber 422. The flip lid may 420 also have a protrusion or similar mechanism that allows it to reversibly lock with the collar 410.

When the flip lid 420 is rotated about the hinge (defined by the recess 418 and protrusions 422) into a storage position, the straw 400 is bent inward towards, and lies against blocking protrusion 416. A front edge 428 of the flip lid 420 contacts a portion of the straw 400, which causes the straw 400 to flex about a distal portion to the bottle 10. As the flip lid 420 moves from an open position to a closed position, the front edge 428 of the flip lid 420 travels over a length of the straw 400. When the flip lid 420 is in the closed position, the straw 400 will be completely within a gap in the raised chamber 424 provided between the flip lid 420 and the bottle 10. An advantage of having a softer durometer bottom portion is the added flexibility of the straw 400 to flex during this process.

As mentioned previously, the bottle 10 described herein includes all of the features and functionality discussed above.
