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
The distal end 16 of the lid 10 refers to the portion farthest away from the user during use, whereas the proximal end 18 refers to the portion of the rim 12 facing the user during use, generally adjacent to a drink aperture 20. The proximal end 18, or a portion thereof may be shaped to form a pronounced drinking spout or lip 22, for example by extending vertically to a greater degree than the distal end 16 (
The lid 10 further includes a central hub 24 spaced inwardly from the rim 12, separated therefrom by a lower channel 26. In the illustrated embodiments, the hub 24 is generally cylindrical and the channel 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 illustrated hub 24 and channel 26 may be preferred to provide enhanced drainage.
The hub 24 is defined by a top wall 28 and a sidewall 30 extending downwardly from the perimeter of the top wall 28 to form a generally closed inner border of the channel 26. A drink aperture 20 extends through the sidewall 30 in facing relationship with a portion of the proximal end 18 of the rim 12. The sidewall 30 may include an open steam vent 32 (
The channel 26 is generally inclined or sloped downwardly from the distal end 16 of the rim 12 to the proximal end 18, as shown in
A arcuate portion of the channel adjacent to the drink aperture 20 is defined by a drainage wall 34 extending between the drink aperture 20 and a lower end of the rim proximal end 18 (
In the orientation of
The proximal end 18 of the rim 12 (
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 drinking spout 22 if provided) of the rim 12, and tips the lid 10 and container towards himself/herself, A beverage in the container pours out of the drink aperture 20, moves over the drainage wall 34 and the proximal end 18 (and drinking spout 22 if provided) and into the user's mouth. The user then tips the lid 10 maid container away from himself/herself to halt the flow of beverage. Much of the liquid positioned at that time between the drink aperture 20 and the user's mouth flows back into the drink aperture 20, but some may remain in the channel 26. The differently inclined portions of the channel 26 and drainage wall 34 cooperatively create a “funnel” effect that efficiently directs and drains all of the beverage through the drink 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.
