Description

CLAIM OF PRIORITY

This application claims priority U.S. Provisional Patent Application Ser. No. 62/840,779, filed on Apr. 30, 2019, the entire contents of which are hereby incorporated by reference.

TECHNICAL FIELD

This disclosure relates to a liquid handling vessel, and more particularly to a liquid handling vessel that has one or more grooves.

BACKGROUND

Liquid handling vessels are used to hold and pour out liquid contents. One common challenge shared by such vessels is residual liquid dripping down the outer side wall of the liquid handling vessels during or after pouring of the liquid contents. Such dripping of residual liquids can result in undesirable consequences. Sometimes the residual liquid is a stream of liquid or droplets of liquid. The residual liquid may get on the hands of the user or the surface on which the liquid handling vessel is placed.

For example, when a user takes a drink from a drinking vessel such as coffee mugs or a drinking glass (i.e., the user transfers the liquid content of the drinking vessel to the user's mouth) residual liquid from the drinking vessel (e.g., coffee, water, juice, tea) often travels down the side of the drinking vessel and onto the surface where drinking vessel is placed, resulting in stains or a mess which requires cleaning up. The residual liquid can also transfer from the outer sidewall of the liquid handling vessels to the user's hands (e.g., when the user is holding a vessel), which is undesirable. Similarly, when a user pours paint out from a paint can, residual paint from the paint can often travel down the side of the paint can.

A number of solutions are currently available for mitigating the undesirable effects of residual liquid dripping down the side of a liquid handling vessel. One such solution is placing a coaster between the liquid handling vessel and the surface on which the vessel is placed to prevent the residual liquid from making contact with the surface on which the vessel is placed. However, this solution results in the residual liquid making contact with the coaster, which can result in staining of the coaster and/or require cleaning of the coaster after use.

DETAILED DESCRIPTION

This specification describes liquid containing vessels with liquid retention features to capture, retain, and/or absorb residual liquid. The liquid retention features can be implemented in the form of one or more grooves on the outer side wall of liquid containing vessels to prevent or reduce residual liquid or droplets from traveling down the outer side wall of the liquid handling vessel, making contact with the surface on which the liquid containing vessels are placed, and/or making contact with a hand of a user.

FIG. 1 illustrates a liquid handling vessel 100 including a side wall 102 and a bottom surface 104. The liquid handling vessel 100 is cylindrical and is 4.1 inches tall and 3.4 inches in diameter, but other dimensions can be used. The side wall 102 is sized to structurally support the liquid handling vessel 100. The side wall 102 is 0.125 inches thick, but other thickness can be used. For example, in some cases, the side wall is greater than 0.080 inches and less than 0.150 inches. The inside of the liquid handling vessel 100 defines a receptacle for liquid. The liquid capacity of the liquid handling vessel 100 is 11 oz for an 8 point loading and 13 oz for a full loading, but some liquid handling vessels have different capacities. When empty, the weight of the liquid handling vessel 100 is about 300 grams.

The side wall 102 has a liquid retention feature in the form of groove 101 on the outer surface of the side wall 102. The groove 101 is long and narrow indentations built into a side wall 102 of the liquid containing vessel 100, generally sized and positioned for allowing the residual liquid to enter the groove. The groove 101 is also considered a depression or a channel on the entire circumference of side wall 102 of the liquid containing vessel 100.

The groove 101 is located on the upper half 102a of the outer side wall 102. The upper half 102a of the side wall 102 is positioned further from the bottom surface 104 of the liquid handling vessel. The lower half 102b of the side wall 102 is adjacent to the bottom surface 104. The groove 101 in the liquid handling vessel 100 is configured to retain residual liquid. The groove 101 is 0.125 inches in height (vertical direction) and 0.0625 inches in depth (radial direction), but other groove dimensions can be used. In some cases, a depth of the groove into a side wall is greater than 0.080 inches and less than 0.150 inches. In this way, groove 101 occupies half of the side wall 102 of the liquid handling vessel 100. The groove 101 is a closed loop and is parallel or substantially parallel to the top edge 103 of the liquid handling vessel. Liquid handling vessel 100 is made from Stoneware and includes the following material content: China Clay 50-60%, Quartz 30-45%, Feldspar 6-12%, and Steatite 2-4%, but other materials can be used.

FIG. 2 illustrates a liquid handling vessel 200 that is substantially similar to the liquid handling vessel 100 but also includes a handle 204. Liquid handling vessel 200 is in the form of a coffee mug. Liquid handling vessel 200 includes a groove 201 located within an upper half 202a of a side wall 202. The groove 201 is located between a top edge 203 of the side wall 202 and the upper-most edge of where the handle 204 meets the side wall 202.

FIGS. 3A-3D illustrate a liquid handling vessel 300 that is substantially similar to the liquid handling vessel 100 or the liquid handling vessel 200, includes various types of grooves 302, 304, 306, 308 on an outer side wall 310 of the liquid handling vessel 300.

FIG. 3A illustrates a rectangular cross-sectioned groove 302 located on the outer side wall 310 of the liquid handling vessel 300. The rectangular cross-sectioned groove 302 is substantially similar to the groove 101 of liquid handling vessel 100. The rectangular cross-sectioned groove 302 has side walls 312 that are straight angled relative to a bottom surface 314 of the groove 302. The rectangular cross-sectioned groove 302 occupies less than half of the side wall 312 of the liquid handling vessel 300. The location of the rectangular cross-sectioned groove 302 aids in the groove's ability to capture and retain the residual liquid or droplets that travel down the outer side wall 310 of the liquid handling vessel 300. Dripping residual fluid is then captured and retained in the groove 302. In some cases, the residual fluid is absorbed in the groove 302 by an absorbing porous material, such as a sponge.

FIG. 3B illustrates a trapezoidal cross-sectioned groove 304 located on the outer side wall 310 of the liquid handling vessel 300. The trapezoidal cross-sectioned groove 304 has an inner surface 316 that is wider than an opening on the side wall 310. The side walls 318 of the groove 302 are angled inward to accommodate the wider inner surface 316 relative to the opening on the side wall 310.

FIG. 3C illustrates a fish-hook cross-sectioned groove 306 located on the outer side wall 310 of the liquid handling vessel 300. The fish-hook cross-sectioned groove 306 includes a curved inner surface 318 that defines a reservoir 320 located at the bottom of the groove 306. The reservoir 320 is sized to contain an amount of residual fluid.

FIG. 3D illustrates a rhomboidal cross-sectioned groove 308 located on the outer side wall 310 of the liquid handling vessel 300. The rhomboidal cross-sectioned groove 308 includes a bottom surface 322 and side walls 324 that are parallel and angled relative to the bottom surface 322. The shape of the groove 308 captures the water in a reservoir 324.

In addition to the various types of grooves 302, 304, 306, 308 shown in FIGS. 3A-3D, other cross-sectional shapes can be used. In some cases, the cross-section can vary along the circumference of the outer side wall of the liquid handling vessel. The specific groove chosen can depend on the manufacturing process to produce the liquid handling vessel. In some cases, retention of the residual liquid by the grooves is dependent on the physical characteristics of the liquid (e.g., viscosity, thixotropicity, and/or hydrophobicity). The geometric features of the grooves take into account the physical characteristics of the liquid and can be sized appropriately for an intended liquid. For example, liquid handling vessels for highly viscous liquids can have grooves with larger cross-sectional dimensions. In some implementations, the cross-sectional area of the groove can be small (e.g., less than 1×10⁻⁶ m²), large (e.g., 100×10⁻⁶ m²), or somewhere between. In some cases, the height of the groove is 0.125 inches, a depth is 0.0625 inches, and a dimeter of the liquid handling vessel is 3.4 inches. In addition, coatings can be used to alter the hydrophobicity of the liquid handling vessel and/or grooves.

While only one groove is depicted in liquid handling vessel 100, 200, 300, the grooves can be implemented as multiple grooves or as patterns of one or more grooves on the side walls. In some implementations, a liquid handling vessel can include, on its outer side wall, two or more grooves, such that residual liquid that is not captured by the upper-most groove can be captured by other grooves located below the upper-most groove. Two or more grooves allow for a greater total volume of residual liquid that can be captured and retained by the grooves as compared to a single groove.

FIGS. 4A-4C illustrate various liquid handling vessels 400a, 400b, 400c that are substantially similar to the previously described liquid handling vessels. Each of the liquid handling vessels 400a, 400b, 400c include a different arrangement of grooves on an outer side wall of the liquid handling vessel 400a, 400b, 400c.

FIG. 4A illustrates a liquid handling vessels 400a with a first groove 402 vertically separated from a second groove 404. The grooves 402, 404 are substantially similar to groove 101 of liquid handling vessels 100. The grooves 402, 404 are arranged circumferentially around the outer side wall of the liquid handling vessel 400a. The grooves 402, 404 are arranged in the upper half of the liquid handling vessel 400a. In some implementations, more than two grooves can be used. In some implementations, any combination of cross-sections can be used.

FIG. 4B illustrates a liquid handling vessels 400b with a pattered groove 406. The pattered groove 406 is arranged circumferentially around the outer side wall of the liquid handling vessel 400b. The pattered groove 406 is arranged in the upper half of the liquid handling vessel 400b. The pattered groove 406 defines a lattice of pathways for the residual fluid. The lattice includes a top groove that is parallel to the base of the liquid handling vessels 400b and a bottom groove that is also parallel to the base of the liquid handling vessels 400b. The lattice includes various interconnected pathways defining a diamond pattern. In some implementations, other patterns or lattices can be used. In some implementations, multiple patterns can be used. The patterns can be determined from the properties of the liquid or for ascetics.

FIG. 4C illustrates a liquid handling vessels 400c with a wave-like groove 408. The wave-like groove 408 is arranged circumferentially around the outer side wall of the liquid handling vessel 400c. The wave-like groove 408 is arranged in the upper half of the liquid handling vessel 400c. The wave-like groove 408 has a height that cyclically varies along a circumference of the liquid handling vessel 400c. In some implementations, other curves or pathways can be used. In some implementations, multiple patterns can be used. The patterns can be determined from the properties of the liquid or for ascetics.

In some implementations, a vertical height of the one or more grooves on the outer side wall of a liquid handling vessel is different than previously described. For example, for a drinking vessel (e.g., coffee mug, tea cup, and/or drinking glass) may have one or more grooves that are just below where the user's lower lip typically would make contact with the outer side wall of the drinking vessel. For example, a top-most edge of a groove can be less than 5 cm from the top edge of the side wall.

In instances where a drinking vessel has a handle attached to the side wall of the drinking vessel, the groove may be located between the top edge of the side wall and the upper-most edge of where the handle meets the side wall of the drinking vessel. Such placement of a groove can prevent or reduce residual liquid drips from reaching the handle before being captured, retained, or absorbed by the groove.

In other instances, a liquid handling vessel with grooves located in the upper half of the outer side wall can reduce or minimize the total travel distance of the residual liquid down the side wall, thereby allowing for trapping and retention of the residual liquid before the residual liquid has a chance to gain speed and/or momentum, and to minimize the amount of residual liquid that remains on the outer surface of the side wall, which may result in staining or necessitate cleaning.

While the liquid handling vessels previously described are cylindrical, other profiles can be used. Some liquid handling vessels are square or a rounded square. Some liquid handling vessels are side walls angled relative to a bottom surface. Several examples are illustrated in FIGS. 5A-5C.

FIG. 5A illustrates a liquid handling vessel 500a that has a right angle (i.e., 90°) with respect to a bottom surface. Liquid handling vessel 500a is substantially similar to the liquid handling vessels previously described.

FIG. 5B illustrates a liquid handling vessel 500b that has an oblique angle with respect to a bottom surface. A top opening is larger in diameter than a bottom diameter. Liquid handling vessel 500b can resemble the form of a martini glass. Liquid handling vessel 500b still maintains the ability to retain a volume of residual liquid in the channels formed by the one or more grooves on the outer side wall because of surface tension and “teapot” effects of the liquid as previously described.

FIG. 5C illustrates a liquid handling vessel 500c that has an oblique angle with respect to a bottom surface, but the top opening is smaller in diameter than a bottom diameter. Such a design can lower the center of gravity of the liquid contained in the liquid handling vessel 500c and improve the overall stability of the liquid handling vessel 500c.

FIG. 6A shows a photograph of a coffee mug 600 having a single groove 602 that is located in the upper half of the outer side wall. The groove 602 is substantially similar to the groove 101 in liquid handling vessel 100. The groove 602 in the coffee mug 600 is substantially parallel to the top edge of the side wall and is located between the top edge of the side wall and the top edge of where the handle meets the side wall. In other words, the groove 602 is located above the top edge of where the handle meets the side wall.

FIG. 6B shows a photograph of the coffee mug 600 after a user has taken a sip of coffee from the coffee mug 600. Residual coffee 604 drips above the groove and residual coffee 604 is captured and retained by the groove 602. Notably, there is no residual coffee below the groove 602, demonstrating that the coffee mug 600 having a single groove 602 that is located in the upper half of the outer side wall and above the top edge of where the handle meets the side wall can trap and retain residual coffee 604 from traveling down the outer side wall of the coffee mug 600 beyond the groove 602.
