Abstract
A drink cup lid is provided for mounting over the open mouth of a beverage container. A rim of the lid preferably includes an outer mounting skirt, a distal end, and a proximal end. The lid also includes a central hub spaced inwardly of the rim and separated therefrom by a lower channel. The channel is generally inclined downwardly from the distal end to the proximal end, except for a drainage wall portion thereof adjacent to the proximal end of the rim. The drainage wall is inclined upwardly from the drink aperture to the proximal end of the rim. The opposing inclinations of the drainage wall and the remainder of the channel cooperate to create a “funnel” effect that improves drainage of spilled beverage from the channel, through the drink aperture, and back into the container.
Description
- 1. Field of the Invention
- The present invention is directed to lids for drink containers. In particular, the present invention is directed to a lid having improved surface drainage.
- 2. Description of Related Art
- Disposable lids for carry-out beverage containers are well known. The nature of the lid typically varies according to the beverage, with some lids having a perforation for receiving a straw and others having a drink aperture for pouring the beverage directly into a user's mouth. The latter, often called “drink-through” lids, are most often used with hot beverages, such as coffee A typical drink-through lid is described in U.S. Pat. No. 4,589,569 to Clements, which is hereby incorporated herein by reference.
- When a drink-through container is jostled or the user is careless in drinking, the beverage may spill out of the drink aperture and onto the user or elsewhere. Such spillage may be referred to as “primary spillage.” However, it is possible for the spilled beverage to spill or flow back onto the top of the lid, instead of separating or flowing completely out from the container. If the beverage is not adequate drained back into the container, it remains on the lid, and there is the risk that it may spill onto or otherwise unexpectedly contact the user. Such spillage may be referred to as “secondary spillage.” Many advances have been made to reduce the incidence of primary spillage, but there is still the need for improvement with respect to the problem of secondary spillage.
- Accordingly, an object or aspect of the present invention is to provide a container lid having improved drainage to prevent the risk of secondary spillage
- In accordance with the present invention, a drink cup lid is provided with a generally annular rim including an outer mounting skirt, a distal end, and a proximal end. The lid also includes a central hub spaced inwardly of the rim and separated therefrom by a lower channel. The channel is generally inclined downwardly from the distal end to the proximal end, except for a drainage wall portion thereof adjacent to the proximal end of the rim. The drainage wall separates the proximal end of the rim from a drink aperture through a sidewall of the hub and is inclined upwardly from the drink aperture to the proximal end of the rim.
- According to another aspect of the present invention, a drink cup lid is provided with a generally annular rim including an outer mounting skirt, a distal end, and a proximal end. The lid also includes a central hub spaced inwardly of the rim and separated therefrom by an inclined lower channel. A drainage wall defines a portion of the channel adjacent to the proximal end of the rim. The drainage wall extends between the proximal end of the rim and a drink aperture through a sidewall of the hub and has a different inclination attitude than the remainder of the channel

FIGS. 1-14 illustrate embodiments of alid 10 according to the present invention. Thelid 10 includes a generallyannular rim 12 having anouter mounting skirt 14, adistal end 16, and aproximal end 18. The illustratedmounting skirt 14 is of the type typically incorporated into disposable drink-through lids, and is adapted to be press-fit onto the open mouth of a cup or container (not illustrated). Alternatively, the lid could be made without the mounting skirt (not illustrated). The structure of the mounting skirt may take any form without departing from the scope of the present invention, provided that it is suitable for securing thelid 10 to a durable or disposable container. Thelid 10 itself may also be either durable or disposable and manufactured according to known methods with the materials well known in the art for lids. - The
distal end 16 of thelid 10 refers to the portion farthest away from the user during use, whereas theproximal end 18 refers to the portion of therim 12 facing the user during use, generally adjacent to adrink aperture 20. Theproximal end 18, or a portion thereof may be shaped to form a pronounced drinking spout orlip 22, for example by extending vertically to a greater degree than the distal end 16 (FIGS. 1-7 ). Alternatively, as illustrated in the embodiment ofFIGS. 8-14 , theproximal end 18 may be substantially identical to thedistal end 16, thereby defining a level top for therim 12. The present invention, however, is not limited to the particular design or shape of the spout shown inFIGS. 1-7 , as other types and sizes of spouts could also be incorporated thereon (or as shown inFIGS. 8-14 , no spout or lip). - The
lid 10 further includes acentral hub 24 spaced inwardly from therim 12, separated therefrom by alower channel 26. In the illustrated embodiments, thehub 24 is generally cylindrical and thechannel 26 is generally annular, but virtually any other shape is contemplated by and within the scope of the present invention. However, the channel is used for drainage, as will be described in greater detail herein, so the illustratedhub 24 andchannel 26 may be preferred to provide enhanced drainage. - The
hub 24 is defined by atop wall 28 and asidewall 30 extending downwardly from the perimeter of thetop wall 28 to form a generally closed inner border of thechannel 26. Adrink aperture 20 extends through thesidewall 30 in facing relationship with a portion of theproximal end 18 of therim 12. Thesidewall 30 may include an open steam vent 32 (FIGS. 7 and 14 ), especially if thelid 10 is intended for use with a hot beverage, to for example, allow steam to escape from the container and gradually lower the temperature of the beverage. In a preferred embodiment, thesteam vent 32 is diametrically spaced from thedrink aperture 20, facing thedistal end 16 of therim 12. - The
channel 26 is generally inclined or sloped downwardly from thedistal end 16 of therim 12 to theproximal end 18, as shown inFIGS. 7 and 14 . The downwardly inclined portion of thechannel 26 which is obscured by thehub 24 is shown in broken lines. As shown inFIGS. 7 and 14 , this portion of thechannel 26 may be generally parallel to thetop wall 28 of thecentral hub 24, but thetop wall 28 may be substantially horizontal or otherwise non-parallel to the downwardly inclined portion of thechannel 26 without departing from the scope of the present invention. In one embodiment, thechannel 26 has a relatively constant declination angle α as shown, for example, inFIG. 7 . The declination angle α need not be constant, but the slope of thechannel 26 may vary, for example being relatively steep closer to thedistal end 16 of therim 12 and relatively shallow closer to theproximal end 18 of the rim 12 (not illustrated). - A arcuate portion of the channel adjacent to the
drink aperture 20 is defined by adrainage wall 34 extending between thedrink aperture 20 and a lower end of the rim proximal end 18 (FIG. 7 ) or drinking spout 22 (FIG. 14 ). Thedrainage wall 34 is preferably angularly centered about thedrink aperture 20 and has an arcuate extent ω (FIG. 5 ), which is the angle or portion of thechannel 26 defined by thedrainage wall 34. The arcuate extent ω may vary from relatively large so as to be at least coterminous with the drink aperture 20 (FIGS. 6 and 13 ), to relatively small so as to be narrower than the drink aperture 20 (not illustrated). Thedrainage wall 34 is shown inFIGS. 5 and 12 in solid lines to clarify its position, but typically the transition from the downwardly inclined portion of thechannel 26 to the upwardlyinclined drainage wall 34 is more subtle and is not necessarily defined by a visible line. - In the orientation of
FIGS. 7 and 14 , thedrainage wall 34 is inclined upwardly from left to right, which may be referred to as a positive inclination attitude, whereas the remainder of thechannel 26 is inclined downwardly from left to right, which may be referred to as a negative inclination attitude. Hence, the drainage well 34 and the remainder of thechannel 26 have different inclination attitudes, which configuration improves the drainage characteristics of thelid 10, as will be described in greater detail herein. In one embodiment, thedrainage wall 34 has an inclination angle β (FIG. 7 ). Preferably, thedrainage wall 34 has a relatively constant inclination angle β. The inclination angle β need not be constant, but the slope of thedrainage wall 34 may vary, for example being relatively shallow immediately adjacent to thedrink aperture 20 and relatively steep adjacent to theproximal end 18 or drinking spout 22 (not illustrated). - The
proximal end 18 of the rim 12 (FIG. 14 ) or the drinking spout or lip 22 (FIG. 7 ) may have a positive inclination attitude, similar to thedrainage wall 34. InFIGS. 7 and 14 , theproximal end 18 or drinkingspout 22 has an inclination angle θ. The inclination angle θ may be different from the drainage wall inclination angle β. Preferably, theproximal end 18 or drinkingspout 22 has a relatively constant inclination angle θ. The inclination angle θ need not be constant, but the slope may vary or theproximal end 18 or drinkingspout 22 may be substantially vertical (not illustrated). - In use, the user grips a container (not illustrated) covered by the
lid 10, puts his/her lips on or adjacent to the proximal end 18 (or drinkingspout 22 if provided) of therim 12, and tips thelid 10 and container towards himself/herself, A beverage in the container pours out of thedrink aperture 20, moves over thedrainage wall 34 and the proximal end 18 (and drinkingspout 22 if provided) and into the user's mouth. The user then tips thelid 10 maid container away from himself/herself to halt the flow of beverage. Much of the liquid positioned at that time between thedrink aperture 20 and the user's mouth flows back into thedrink aperture 20, but some may remain in thechannel 26. The differently inclined portions of thechannel 26 anddrainage wall 34 cooperatively create a “funnel” effect that efficiently directs and drains all of the beverage through thedrink aperture 20 and into the container. It will be appreciated that an inclined channel without a drainage wall may tend to cause beverage to congregate at a portion of the lid between the drink aperture and the proximal end of the rim, thereby increasing the risk of secondary spillage. - It will be understood that the embodiments of the present invention which have been described are illustrative of some of the applications of the principles of the present invention. Numerous modifications may be made by those skilled in the art without departing from the true spirit and scope of the invention, including those combinations of features that are individually disclosed or claimed herein. For these reasons, the scope of the invention is not limited to the above description, but is as set forth in the following claims.
