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

For example, in some cases, the side wall is greater than 0.080 inches and less than 0.150 inches. The inside of theliquid handling vessel 100 defines a receptacle for liquid. The liquid capacity of theliquid 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 theliquid handling vessel 100 is about 300 grams. - The
side wall 102 has a liquid retention feature in the form ofgroove 101 on the outer surface of theside wall 102. Thegroove 101 is long and narrow indentations built into aside wall 102 of the liquid containingvessel 100, generally sized and positioned for allowing the residual liquid to enter the groove. Thegroove 101 is also considered a depression or a channel on the entire circumference ofside wall 102 of the liquid containingvessel 100. - The
groove 101 is located on theupper half 102 a of theouter side wall 102. Theupper half 102 a of theside wall 102 is positioned further from thebottom surface 104 of the liquid handling vessel. Thelower half 102 b of theside wall 102 is adjacent to thebottom surface 104. Thegroove 101 in theliquid handling vessel 100 is configured to retain residual liquid. Thegroove 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 theside wall 102 of theliquid handling vessel 100. Thegroove 101 is a closed loop and is parallel or substantially parallel to thetop 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 aliquid handling vessel 200 that is substantially similar to theliquid handling vessel 100 but also includes ahandle 204.Liquid handling vessel 200 is in the form of a coffee mug.Liquid handling vessel 200 includes agroove 201 located within anupper half 202 a of aside wall 202. Thegroove 201 is located between atop edge 203 of theside wall 202 and the upper-most edge of where thehandle 204 meets theside wall 202. -
FIGS. 3A-3D illustrate aliquid handling vessel 300 that is substantially similar to theliquid handling vessel 100 or theliquid handling vessel 200, includes various types ofgrooves outer side wall 310 of theliquid handling vessel 300. -
FIG. 3A illustrates a rectangularcross-sectioned groove 302 located on theouter side wall 310 of theliquid handling vessel 300. The rectangularcross-sectioned groove 302 is substantially similar to thegroove 101 ofliquid handling vessel 100. The rectangularcross-sectioned groove 302 hasside walls 312 that are straight angled relative to abottom surface 314 of thegroove 302. The rectangularcross-sectioned groove 302 occupies less than half of theside wall 312 of theliquid handling vessel 300. The location of the rectangularcross-sectioned groove 302 aids in the groove's ability to capture and retain the residual liquid or droplets that travel down theouter side wall 310 of theliquid handling vessel 300. Dripping residual fluid is then captured and retained in thegroove 302. In some cases, the residual fluid is absorbed in thegroove 302 by an absorbing porous material, such as a sponge. -
FIG. 3B illustrates a trapezoidalcross-sectioned groove 304 located on theouter side wall 310 of theliquid handling vessel 300. The trapezoidalcross-sectioned groove 304 has aninner surface 316 that is wider than an opening on theside wall 310. Theside walls 318 of thegroove 302 are angled inward to accommodate the widerinner surface 316 relative to the opening on theside wall 310. -
FIG. 3C illustrates a fish-hookcross-sectioned groove 306 located on theouter side wall 310 of theliquid handling vessel 300. The fish-hookcross-sectioned groove 306 includes a curvedinner surface 318 that defines areservoir 320 located at the bottom of thegroove 306. Thereservoir 320 is sized to contain an amount of residual fluid. -
FIG. 3D illustrates a rhomboidalcross-sectioned groove 308 located on theouter side wall 310 of theliquid handling vessel 300. The rhomboidalcross-sectioned groove 308 includes abottom surface 322 andside walls 324 that are parallel and angled relative to thebottom surface 322. The shape of thegroove 308 captures the water in areservoir 324. - In addition to the various types of
grooves 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

Thegrooves liquid handling vessel 400 a. Thegrooves liquid handling vessel 400 a. In some implementations, more than two grooves can be used. In some implementations, any combination of cross-sections can be used. -
FIG. 4B illustrates aliquid handling vessels 400 b with a patteredgroove 406. The patteredgroove 406 is arranged circumferentially around the outer side wall of theliquid handling vessel 400 b. The patteredgroove 406 is arranged in the upper half of theliquid handling vessel 400 b. The patteredgroove 406 defines a lattice of pathways for the residual fluid. The lattice includes a top groove that is parallel to the base of theliquid handling vessels 400 b and a bottom groove that is also parallel to the base of theliquid handling vessels 400 b. 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 aliquid handling vessels 400 c with a wave-like groove 408. The wave-like groove 408 is arranged circumferentially around the outer side wall of theliquid handling vessel 400 c. The wave-like groove 408 is arranged in the upper half of theliquid handling vessel 400 c. The wave-like groove 408 has a height that cyclically varies along a circumference of theliquid handling vessel 400 c. 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 aliquid handling vessel 500 a that has a right angle (i.e., 90°) with respect to a bottom surface.Liquid handling vessel 500 a is substantially similar to the liquid handling vessels previously described. -
FIG. 5B illustrates aliquid handling vessel 500 b 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 500 b can resemble the form of a martini glass.Liquid handling vessel 500 b 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 aliquid handling vessel 500 c 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 theliquid handling vessel 500 c and improve the overall stability of theliquid handling vessel 500 c. -
FIG. 6A shows a photograph of acoffee mug 600 having asingle groove 602 that is located in the upper half of the outer side wall. Thegroove 602 is substantially similar to thegroove 101 inliquid handling vessel 100. Thegroove 602 in thecoffee 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, thegroove 602 is located above the top edge of where the handle meets the side wall. -
FIG. 6B shows a photograph of thecoffee mug 600 after a user has taken a sip of coffee from thecoffee mug 600.Residual coffee 604 drips above the groove andresidual coffee 604 is captured and retained by thegroove 602. Notably, there is no residual coffee below thegroove 602, demonstrating that thecoffee mug 600 having asingle 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 retainresidual coffee 604 from traveling down the outer side wall of thecoffee mug 600 beyond thegroove 602. - A number of embodiments of the systems and methods have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of this disclosure. Accordingly, other embodiments are within the scope of the following claims.
