DETAILED DESCRIPTION

A first embodiment of a drink cup 10 in accordance with the present disclosure is shown in FIGS. 1-14. The drink cup 10 includes a brim 14, a body-strengthening system 16, and a grip portion 18, as shown in FIGS. 1-3. A second embodiment of a drink cup 210 in accordance with the present disclosure is shown in FIGS. 15-28.

The drink cup 10 includes the body 12, the brim 14, the body-strengthening system 16, and the grip portion 18, as shown in FIGS. 1-3. Body 12 includes a floor 20 and a side wall 22 that cooperate to form an interior region 24. Brim 14 is coupled to body 12 to frame an opening into interior region 24. Body-strengthening system 16 is coupled to body 12 between floor 20 and brim 14 and is configured to provide means for minimizing a weight of drink cup 10 while maximizing the rigidity of a selected portion of drink cup 10 so that unintended deformation of drink cup 10 is minimized. Grip portion 18 is located between floor 20 and brim 14 and is configured to provide enhanced gripability to drink cup 10, strength to a selected portion of drink cup 10 so that unintended deformation of drink cup 10 is further minimized, and decreased heat transfer between a user’s hand and interior region 24. For example, the user’s hand may contact or touch less of the drink cup 10 due to the grip portion 18 thereby minimizing heat transferred from the user’s hand to the drink cup 10 (and thus, to liquid in the drink cup 10). Grip portion 18 also provides a path for condensation to flow along the drink cup 10 thereby minimizing slickness of the drink cup 10, which further provides enhanced gripability of the drink cup 10.

A lower end of annular band 50 is coupled to the upper end of second annular strip 48 and an upper end of annular band 50 is coupled to a lower end of brim 14. Annular band 50 is substantially flat and/or planar such that annular band 50 extends along a straight path. In some embodiments, stack shoulder 26 provides a third strengthening unit of body-strengthening system 16.

As shown in FIG. 5, as lower portion 22L of side wall 22 extends from floor 20 to second strengthening unit 30, lower portion 22L has a generally increasing diameter. A distance between an uppermost portion of lower portion 22L of side wall 22 to central axis A is less than the fourth distance D4 between peak 30P and central axis A, as shown in FIG. 7. As upper portion 22U of side wall 22 extends from first strengthening unit 28 to stack shoulder 26, upper portion 22U has a generally increasing diameter. As grip portion 18 extends from second strengthening unit 30 to first strengthening unit 28, grip portion 18 has a generally increasing diameter.

Grip portion 18 is located between first strengthening unit 28 and second strengthening unit 30, as shown in FIGS. 1 and 8. Grip portion 18 includes a plurality of protrusions 52 that provide texture to grip portion 18. Textured grip portion 18 provides enhanced gripability of drink cup 10 such that it is easier for a user to grip and hold drink cup 10. Textured grip portion 18 also provides strength to portions of drink cup 10. Lastly, textured grip portion 18 provides for a reduced heat transfer through drink cup 10 from the user’s hand as the surface area of grip portion 18 that the user grips and holds is decreased relative to a drink cup without the textured grip portion 18. Grip portion 18 may also be referred to as a middle portion.

The plurality of protrusions 52 is arranged in a pattern throughout grip portion 18, as shown in FIG. 8. A first portion of the plurality of protrusions 52 is aligned in a plurality of rows 52R that extend circumferentially entirely around central axis A. A second portion of the plurality of protrusions 52 is aligned in a plurality of columns 52C that extend entirely vertically between first strengthening unit 28 and second strengthening unit 30.

Each of the plurality of protrusions 52 includes a first lateral face 54, a second lateral face 56 opposite first lateral face 54, a third lateral face 58 located between first lateral face 54 and second lateral face 56, and a fourth lateral face 60 opposite third lateral face 58, as shown in FIGS. 8 and 9.

In other words, a corner formed by second lateral face 56 and fourth lateral face 60 of a respective protrusion 52 in a column contacts first side wall 58A of third lateral face 58 of a directly adjacent and neighboring protrusion 52 of the column.

In each of the plurality of rows 52R, apex 52A of each of the plurality of protrusions 52 in a respective row 52R are offset with one another, as shown in FIG. 9. In each of the plurality of columns 52C, apex 52A of each of the plurality of protrusions 52 in a respective column 52C are offset with one another, as shown in FIG. 9. Apex 52A of each of the plurality of protrusions 52 in a respective row 52R are offset from apex 52A of each of the plurality of protrusions 52 in a respective column 52C, as shown in FIGS. 9 and 11.

First lateral face 54 of each of the plurality of protrusions 52 are parallel to one another, as shown in FIG. 9. Second lateral face 56 of each of the plurality of protrusions 52 are parallel to one another. Third lateral face 58 of each of the plurality of protrusions 52 are parallel to one another. Fourth lateral face 60 of each of the plurality of protrusions 52 are parallel to one another.

Each of the plurality of protrusions 52 in a respective column 52C is located partially between two neighboring protrusions in a row 52R and partially between two neighboring protrusions 52 in a directly adjacent and neighboring row 52R. For ease of example, a first protrusion 62, a second protrusion 64, and a third protrusion 66 will be discussed. First protrusion 62 and second protrusion 64 are arranged in a row 52R, and third protrusion 66 is arranged in a column 52C.

Third protrusion 66 is located partially circumferentially between first protrusion 62 and second protrusion 64. Fourth lateral face 60 of third protrusion 66 is located circumferentially between third lateral face 58 of first protrusion 62 and second lateral face 56 of third protrusion 66. Second lateral face 56 of third protrusion 66 is located circumferentially between fourth lateral face 60 of third protrusion 66 and first lateral face 54 of second protrusion 64. Different protrusions 52 arranged in a directly adjacent row 52R are located on either side of first lateral face 54 and third lateral face 58 of third protrusion 66.

In some embodiments, each of the plurality of protrusions 52 is a square pyramidal-shape. In some embodiments, each of the plurality of protrusions 52 is a triangular pyramidal-shape. In some embodiments, each of the plurality of protrusions 52 is a pentagonal pyramidal-shape. In some embodiments, each of the plurality of protrusions 52 is a hexagonal pyramidal-shape. In some embodiments, each of the plurality of protrusions 52 is diamond shape.

In some embodiments, drink cup 10 is formed of polypropylene. In one example, side wall 22 of drink cup 10 has a frustoconical shape. Each of first and second strengthening units 28, 30 is coupled to side wall 22 and are arranged to deviate from the frustoconical shape of side wall 22. In one example, first and second strengthening units 28, 30 extend away from side wall 22, toward central axis A, or combinations thereof. Each of first and second strengthening units 28, 30 can be seen as a deviation or interruption of the frustoconical shape of side wall 22. It will be understood that the drawings are drawn to scale.

Another drink cup 210 is shown in FIGS. 15-28. The drink cup 210 is substantially similar to the drink cup 10. The description of the drink cup 10 is incorporated by reference to apply to the drink cup 210, except in instances when it conflicts with the specific description and drawings of the drink cup 210.

A drink cup 210 includes a body 212, a brim 214, a body-strengthening system 216, and a grip portion 218, as shown in FIGS. 15-17. Body 212 includes a floor 220 and a side wall 222 that cooperate to form an interior region 224. Brim 214 is coupled to body 212 to frame an opening into interior region 224. Body-strengthening system 216 is coupled to body 212 between floor 220 and brim 214 and is configured to provide means for minimizing a weight of drink cup 210 while maximizing the rigidity of a selected portion of drink cup 210 so that unintended deformation of drink cup 210 is minimized. Grip portion 218 is located between floor 220 and brim 214 and is configured to provide enhanced gripability to drink cup 210, strength to a selected portion of drink cup 210 so that unintended deformation of drink cup 210 is minimized, and decreased heat transfer between a user’s hand and interior region 224. For example, the user’s hand may contact or touch less of the drink cup 210 due to the grip portion 218 thereby minimizing heat transferred from the user’s hand to the drink cup 210 (and thus, to liquid in the drink cup 210). Grip portion 218 also provides a path for condensation to flow along the drink cup 210 thereby minimizing slickness of the drink cup 210, which further provides enhanced gripability of the drink cup 210.

Body 212 includes floor 220 and side wall 222, as shown in FIGS. 15 and 18. Side wall 222 is coupled to floor 220 to extend upwardly away from floor 220.
