A common problem associated with the consumption of a beverage containing ice cubes is that the ice cubes float on the surface of the beverage and therefore come in contact with the lips of the drinker. In addition to this problem, the ice cubes often greatly impede the flow of the beverage into the drinker's mouth, frustrating the drinker's desire simply to drink the beverage, rather than maneuver around ice cubes with his or her lips. When one tips the glass up to enhance the flow of liquid, the ice may come rushing toward the drinker, spilling the contents of the container on the drinker, particularly when the drinker is attempting to consume the final sip or two of the beverage and tilts the container at an extreme angle.

SUMMARY OF THE INVENTION In the present invention, an ice restraining device is provided which prevents ice floating in a beverage from coming into contact with the lips of the drinker. The restrainer comprises a barrier and a fitting, which is adapted to be mounted to the rim of a glass, most preferably any size or shape glass.

These and other objects, advantages, and features of the present invention will become apparent upon review of the following specification in conjunction with the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the preferred embodiment, an ice restraining device is provided, shown generally in Figs. 1 and 3-9 and depicted by the reference numeral 10. Restrainer 10 includes a barrier 12 for restraining the ice within the beverage container and a fitting 14 for mounting restrainer 10 onto the rim or lip of the container.

In the most preferred embodiment, shown in Figs. 1 and 3-5, fitting 14 includes a narrow lower groove 16 which allows attachment of restrainer 10 to the rim 52 of a beverage container such as a glass 50 by gripping rim 52 of glass 50 tightly. Fitting 14 is typically made of plastic, and has enough flexibility to admit rim 52 of glass 50 into lower groove 16 but enough stiffness to grip rim 52 snugly. It is also preferably sufficiently flexible and sufficiently short in length, that it can be flexed to accommodate the different curvatures of different sized glasses. The length of fitting 14 extends only a fraction of the circumference of the glass, not all of the way around it. Indeed it preferably extends just a sufficient distance to give it a good grip on the edge of the glass, but not so far that it cannot be flexed to accommodate different sized glasses having different curvatures. The depth of lower groove 16 is sufficient to ensure an adequate grip and is typically about ^X A to V_ inch. In other embodiments, fitting 14 may also be secured by means of a knurled thumbscrew, or fitting 14 may be an adjustable clamp similar to a paper clamp.

Fig. 1 further shows that although the fitting 14 and lower groove 16 are slightly curved to match the curve of rim 52 of glass 50, fitting 14 also has an upper groove or pivot slot 18 which is straight to permit pivoting. There is sufficient body in fitting 14 to permit a straight groove 18 to be superimposed on the curved fitting 14.

In this embodiment retainer 10 includes a handle 20. Attached to handle 20 is pivot bar 22, and standoff 24 is positioned between handle 20 and barrier 12. Handle 20

and fitting 14 snap together by placing pivot bar 22 into upper groove 18. The fit between upper groove 18 and pivot bar 22 is moderately tight. This allows handle 20 and barrier 12 to remain in whatever position they are placed in by the user. By pressing downward on handle 20, the user can tilt barrier 12 upward and even out of the glass 50 to permit more ice to be added to the beverage. By lifting upward on handle 20, the user can submerge barrier 12 to the desired degree, thereby submerging ice held below barrier 12. Because the fit between groove 18 and bar 22 is somewhat snug, the buoyancy of ice below barrier 12 is not enough to lift barrier 12 upwards. For embodiments in which barrier 12 cannot be tilted upward high enough to permit ice to be added to the glass, handle 20 and barrier 12 can be temporarily disconnected from fitting 14 (either by vertical or horizontal motion relative to fitting 14), or fitting 14 can be detached from the glass temporarily to permit ice to be replenished.

The design of pivot bar 22 and upper grove 18 may vary. As shown in Fig. 1A, the rear wall 15 of upper grove 18 may be partly cut away so as not to block the motion of handle 20 when it is pushed down sufficiently to lift barrier 12 completely out of glass 50. Pivot bar may also be a ball-shaped or spherical pivot member 23, as shown in Fig. IB, with groove 18 being a ball-shaped or spherical cavity having a circular inner cross section.

Because the weight of a glass is considerable, particularly when it contains a beverage, one may, with one hand, lift upward or push downward on handle 20 readily with miriimal risk of tipping over the glass. For this reason, when the glass is first filled and ice is in position, the beverage can be stirred by moving handle 20 up and down to cool the beverage residing above the barrier 12, thus ensuring that the beverage reaching the drinker is ice cold despite absence of ice above barrier 12. The exact design of barrier 12 may vary. Fig. 1 depicts a simple grid design;

Fig. 5 depicts a barrier based on the dollar sign. Barrier 12 may contain cartoon or superhero or action figure promotional patterns and images, or corporate logos, for the amusement of children and adults. The only requirement is that large ice cubes are not allowed to cross the barrier. An unlimited number of surface shapes, even including surfaces without openings, and even including non-planar shapes, may provide satisfactory ice retaining function.

The depth of the barrier 12 in the glass may be set by manufacturing handle 20 and barrier 12 with different vertical standoff 24 lengths to suit different tastes. A typical

standoff 24 length may be V_ inch to 2 inches. The angle formed between standoff 24 and barrier 12 need not be the angle shown in Figs. 1 and 3, but may be a right angle or even an angle less than 90 degrees.

Additionally, the diameter of the barrier 12 can vary to accommodate glasses of different sizes and shapes. Because barriers can be interchangeable, the user may optionally purchase barriers 12 and fittings 14 separately and combine them as desired.

Certain glasses have flat rather than curved edges. For such glasses, the design described in Fig. 1 is modified to omit curvature of fitting 14. Further, in such cases barrier 12 may be more square or polygonal than circular so as to correspond to the shape requirements imposed by the particular glass.

Fig. 2 shows the problems of drinking beverages without the ice restraining device of the preferred embodiment. The attempt to drink the beverage 60 brings ice 70 toward the lips 102 of the drinker 100, thus blocking the flow of beverage 60 into the drinker's mouth and frequently bringing the ice 70 into unwanted contact with the drinker's lips 102. Because the ice floats, a portion of its surface 72 protrudes above the surface 62 of the beverage 60, which reduces its effectiveness in cooling the liquid, particularly near the bottom of the glass 50.

Fig. 3 shows schematically the action of the present invention, in the most preferred embodiment, in preventing the problems shown in Fig. 2. The ice 70 remains away from the drinker's mouth at all times and is mostly submerged completely, exposed surfaces 72 being minimal. Further, in the embodiment shown, the tilt of barrier 12 ensures that ice is present near the surface 62 whether the glass is tilted for drinking or is in a resting position. The ice 70 is retained by barrier 12 which is situated below rim 52 of glass 50 by standoff 24. Handle 20 with standoff 24 is in turn affixed to rim 52 of glass 50 by means of fitting 14. The handle 20 is used to pivot barrier 12 about pivot bar 22 held within upper groove 18. Beverage 60 is also more sufficiently cooled near the bottom of glass 50.

In an alternate embodiment of the invention as shown in Fig. 5a, the ice restraining barrier is mounted non-pivotally to the rim of the glass by two standoffs positioned so as to align approximately with the intersection between the nostrils and nasolabial fold of the drinker when in use.

Another embodiment of the present invention is shown in Figs. 6 and 7. In this embodiment, fitting 14 is expanded to a semi-circular shape and includes cover 26. In

this embodiment, cover 26 provides a means of avoiding spillage of the beverage, and the greater contact area of fitting 14 with rim 52 of glass 50 provides further security of positioning of fitting 14. Standoff 24 may be attached to fitting 14 without pivoting capability, or pivoting capability analogous to that described above may be provided. In the embodiment shown in Figs. 6 and 7, submerged barrier 12 may cover less than the majority of the cross-sectional area of the glass interior. Alternatively, cover 26 may be "horseshoe" shaped to provide room for the drinker's nose to enter the glass.

A third embodiment is shown in Fig. 8. In this embodiment, barrier 12 is located at approximately the level of rim 52 of glass 50 and is enclosed in a housing 28 that fully encloses the opening of glass 50. The user drinks the beverage not by placing his or her lips on rim 52 of the glass 50, but by using spout 30. In this embodiment, the glass is rendered spill-proof by housing 28 except for the area of the spout 30. Barrier 12 may be positioned at or above the level of rim 52, or may be placed below rim level by attaching a standoff to the bottom of housing 28 which is in turn attached to barrier 12. Although snap-on caps with spouts are known in the prior art, they are not generally contemplated for use in preventing ice from reaching the drinker and would be of minimal effectiveness in this regard because both large ice cubes and crushed ice tend to block spout 30 due to the absence of barrier 12. Barrier 12, in Fig. 8, allows beverage 60 to pass freely to the drinker without restriction from large ice cubes, overcoming the problem of the narrow neck of spout 30 that in known snap-caps may be blocked by ice. In a modified form of the third embodiment, as illustrated in Fig. 9, barrier 12 can be effective for both blocking the movement of crushed ice 74 toward the drinker and for permitting the passage of beverage 60 through the barrier 12 by making use of a sloped or conical barrier 12. This feature provides not only more surface area for beverage filtration through the crushed ice 74 but may also provide a passageway through the crushed ice 74 itself as shown in Fig. 9, thus greatly facilitating drinking.

The above description is considered that of the preferred embodiments only.
