DETAILED DESCRIPTION

FIGS. 1-4 illustrate a first embodiment of the drinking cup assembly. As shown in the figures, drinking cup assembly 1000 includes drinking cup 1200 and retainer 1400. Drinking cup 1200 may be configured to hold a liquid, such as a beverage, which a person intends to drink. The figures show a liquid and ice in drinking cup 1200.

Drinking cup 1200 may be formed from any material capable of holding the liquid. For example, the material of drinking cup 1200 may be one or more of: plastic, glass, metal such as steel or aluminum, bamboo, wheat, corn, paper, waxed paper, sugarcane, and/or any other material. Drinking cup 1200 may or may not be one or more of: disposable or non-disposable, recyclable or non-recyclable, compostable or non-compostable, or biodegradable or non-biodegradable. Drinking cup 1200 may be provided with, or may be provided separate from, retainer 1400. Drinking cup 1200 may be any of clear, translucent, or opaque. Drinking cup 1200 may be sized and shaped to hold any desired quantity of liquid.

Retainer 1400 may be formed from any material capable of retaining, to at least some degree, any solid, semi-solid, non-liquid, or semi-liquid within drinking cup 1200, while permitting another solid, semi-solid, non-liquid, or semi-liquid of or below a predetermined size, or permitting the liquid, within drinking cup 1200, to flow out of drinking cup 1200, such as when a person tips drinking cup 1200 intending to drink the liquid disposed therein. By way of example, retainer 1400 may retain within drinking cup 1200 one or more of: ice, an ice-substitute, a fruit, a vegetable, or any other object, while permitting the user to drink the liquid within drinking cup 1200. Retainer 1400 may be any of clear, translucent, or opaque.

Retainer 1400 may include one or more openings 1420 sized, shaped, oriented, and/or disposed to permit the liquid in drinking cup 1200 to flow through retainer 1400, while preventing, to at least some degree, an object (such as the ice or the ice-substitute) within the liquid from flowing through retainer 1400 and/or out of drinking cup 1200.

Retainer 1400 may include any number of openings 1420, such as, for example, one, two, three, four, five, six, seven, eight, or more opening 1420. As shown in the figures, retainer 1400 includes eight openings 1420. Openings 1420 may be formed anywhere within or on retainer 1400. For example, openings 1420 may be formed around an outer circumference of bottom surface 1460 of retainer 1400. Bottom surface 1460 may be any shape, such as substantially flat or dome-shaped, for example. Some or all openings 1420 may be the same size as, or different sizes than, one or more openings 1420. Openings 1420 may be any shape, including but not limited to slots, circles, arcs, or polygons, or any other shape. Openings 1420 may be distributed equally on bottom surface 1460 of retainer 1400, or may be distributed unequally on bottom surface 1460 of retainer 1400. As shown in the figures, openings 1420 are slots of substantially the same size, distributed equally on bottom surface 1460.

Retainer 1400 may include attachment section 1470, configured to attach retainer 1400 to an upper edge of drinking cup 1200. Attachment section 1470 may be sized, shaped, located, or otherwise disposed to permanently or temporarily attach retainer 1400 to drinking cup 1200. For example, attachment section 1470 may be sized, shaped, and/or made of an appropriate material, such that attachment section 1470 achieves a snap-fit (that is, an interference fit resulting from deformation of attachment section 1470) with the upper edge of drinking cup 1200.

For example, attachment section 1470 may permanently attach retainer 1400, which is intended to be disposable, to drinking cup 1200 that also is intended to be disposable. Attachment section 1470 may attach to any portion of a circumference of the upper edge of drinking cup 1200. For example, attachment section 1470 may attach to about 10%, 25%, 50%, 75%, 80%, 90%, 95%, 99%, or 100% of the circumference of the upper edge of drinking cup 1200. Attachment section 1470 may be connected to side wall 1480, which is connected to bottom surface 1460, of retainer 1400. Side wall 1480 may extend any percentage around the circumference of an inner wall or surface of drinking cup 1200. For example, side wall 1480 may extend about 10%, 25%, 50%, 75%, 80%, 90%, 95%, 99%, or 100% of the circumference of the inner wall or surface of drinking cup 1200. Openings 1420 may or may not be formed in at least some portion of side wall 1480.

A method of using drinking cup assembly 1000 may include filling drinking cup 1200 with ice or an ice-substitute, as well as a liquid. The method may include attaching attachment section 1470 of retainer 1400 to an upper edge of drinking cup 1200, before or after adding the ice, ice substitute, and/or liquid to drinking cup 1200, thereby to secure retainer 1400 to drinking cup 1200. Openings 1420 may be sized, shaped, oriented, and distributed to permit the liquid with drinking cup 1200 to pass through the openings 1420, while openings 1420 may prevent the ice or ice-substitute from passing through openings 1420, such as when the user tips drinking cup 1200 to drink the liquid within drinking cup 1200.

Retainer 7400 may include attachment section 7470, configured to attach retainer 7400 to an inner surface of drinking cup 7200. Attachment section 7470 may be configured to permanently or temporarily attach retainer 7400 to drinking cup 7200. For example, attachment section 7470 may permanently attach retainer 7400, which is configured to be disposable, to drinking cup 7200, also configured to be disposable. Attachment section 7470 may be connected to the inner surface of drinking cup 7200, such as by welding, adhering, gluing, or sonically-welding attachment section 7470 to drinking cup 7200. Attachment section 7470 may be sized and shaped such that when attachment section 7470 and/or retainer 7400 are in a folded-up configuration, as shown in FIG. 22, a plurality of drinking cups 7200 may be nested inside one another. When in the folded-up configuration, retainer 7400 may be disposed entirely within drinking cup 7200. When retainer 7400 is folded down, as shown in FIG. 21 and FIG. 23, at least a portion of retainer 7400 may be any shape, such as flat, or a portion of a dome.

A method of using drinking cup assembly 7000 may be similar to other methods of using drinking cups described herein. A method of using drinking cup assembly 7000 may include removing drinking cup 7200 from a stack of drinking cups where retainer 7400 is folded up as shown in FIG. 22, filling drinking cup 7200 with ice and a liquid, and folding retainer 7400 to a configuration in which retainer 7400 may retain the ice within drinking cup 7200 (that is, from folded up, to folded down), as shown in FIG. 21.

FIGS. 24-25 illustrate an eighth embodiment of the drinking cup assembly. As shown, drinking cup assembly 8000 includes drinking cup 8200 and retainer 8400. Drinking cup 8200 may be similar to the other drinking cups described herein. Retainer 8400 may be similar to the other retainers, except to the extent that retainer 8400 is described below as differing from the other retainers.

Drinking cup 8200 may include retainer attachment section 8220. Retainer attachment section 8220 may be sized, shaped, disposed, and/or oriented to connect with one or more corresponding features of retainer 8400. For example, retainer attachment section 8220 may be a recess formed during molding of drinking cup 8200. Retainer attachment section 8220 may be substantially flat, and may include a protrusion and/or depression cooperating with a corresponding depression or protrusion of retainer 8400. Drinking cup 8200 may also include a grip portion 8240, which provides a reference point for holding drinking cup 8200. For example, grip portion 8240 may be sized, shaped, oriented, and disposed to receive a thumb of the user of drinking cup 8200. Grip portion 8240 may be one or both of a recess or a protrusion. Retainer attachment section 8220 may be located at a top portion of grip portion 8240.

Retainer 8400 may include any number of openings 8420, such as, for example, one, two, three, or more opening 8420. As shown in the figures, retainer 8400 includes three openings 8420. Openings 8420 may be formed anywhere within or on retainer 8400. Openings 8420 may be the same size as, or different sizes than, one or more other openings 8420. Openings 8420 may be any shape, including but not limited to slots, circles, curves, and polygons. Openings 8420 may be distributed equally on retainer 8400, or may be distributed unequally on retainer 8400.

Retainer 8400 may include attachment section 8470, configured to attach retainer 8400 to drinking cup 8200. Attachment section 8470 may be configured to permanently or temporarily attach retainer 8400 to cup 8200. Attachment section 8470 may be substantially flat, and may include a protrusion and/or depression cooperating with a corresponding depression or protrusion of drinking cup 8200. For example, attachment section 8470 may permanently attach retainer 8400, which is intended to be disposable, to drinking cup 8200 that is intended to be disposable. Attachment section 8470 may be connected to the inner surface of cup 8200, such as retainer attachment section 8220, by achieving an interference or friction fit between retainer attachment section 8220 and attachment section 8470. Additionally or in place of the friction fit, welding, adhesive, glue, or sonic-welding may attach retainer attachment section 8220 and attachment section 8470. When retainer 8400 is folded down, at least a portion of retainer 8400 may be any shape, such as flat, or dome-shaped.

One or more of the shape or material of drinking cup 8200, retainer 8400, attachment section 8470, and/or retainer attachment section 8220 may be chosen so that drinking cups 8200 are stacked (that is, nested), when an upper drinking cup 8200 is removed from within a lower drinking cup 8200, the retainer 8400 of the lower drinking cup deploys from a configuration where it is folded against the inner wall or surface of the lower drinking cup 8200, to a configuration away from the wall of the lower drinking cup 8200, without the user having to touch or otherwise manipulate retainer 8400 into an ice-retaining position.

A method of using assembly 8000 may include attaching attachment section 8470 to cup 8200, before or after filling drinking cup 8200 with the liquid and/or ice. Retainer 8400 may be formed such that it is spring biased to a downward position—that is, from a position against the interior surface of wall of drinking cup 8200. Thus, when an upper drinking cup 8200 is removed from an interior of a lower drinking cup 8200, retainer 8400 of the lower drinking cup moves from a position against the interior wall of the lower drinking cup to an ice-retaining position, as shown in FIGS. 19 and 20.
