The lid also has a reclosable flap comprising an arcuate portion of the gripping portion and a bendable portion of the central section. The reclosable flap is bordered on a first side by a first frangible line of separation, and on a second side by a second frangible line of separation, the first and second lines of separation extending inwardly from an edge of the gripping portion. The lid also includes a locking tab forming part of the reclosable flap, extending from the arcuate portion of the gripping portion, and which is able to engage a bottom side of the rim when the reclosable flap is in a closed position.
Description
- A wide variety of lids have been developed to cover containers such as beverage cups. Commercially available lids may be designed for purposes such as preventing spillage and leakage, helping to protect the contents of the container from dust and contaminants, and providing thermal insulation for hot or cold beverages. After the container has been filled and the lid has been applied, a user may access the contents of the container (e.g., for drinking or pouring) by removing all or part of the lid, or by folding back a portion of the lid.
- Some molded lids for beverage cups have included a tear-back flap which, when pulled upward by a lifting tab from an initial closed position, tears a small opening in the lid that enables a user to access the contents. Generally, such lids provide means for the user to lock the lifting tab or another portion of the tear-back flap in an open position. For example, a portion of the tear-back flap may be designed to be able to frictionally engage one or more projections or indentations on the lid, to secure the tear-back flap in an open position.
- In many cases, after opening the tear-back flap, the user may desire to return the tear-back flap to its closed position. In a typical example, after sipping a portion of a beverage through the opening, the user may wish to reclose the lid during a pause in consumption. However, such lids generally are not provided with reliable means for securing the tear-back flap, once opened, in the closed position. Accordingly, the contents of the container may leak or spill, which may result in inconvenience, injury, or property damage. Leakage or spillage may occur, for example, if the container is bumped, tilted, jostled, or if the container is set down in a cup holder of a vehicle that suddenly stops or accelerates.
- A lid for reclosably covering a container is provided. In an illustrative implementation, the lid comprises a gripping portion having an annular channel able to removably receive a rim of the container, and a central section bordered by the gripping portion. The lid also has a reclosable flap comprising an arcuate portion of the gripping portion and a bendable portion of the central section. The reclosable flap is bordered on a first side by a first frangible line of separation, and on a second side by a second frangible line of separation, the first and second lines of separation extending inwardly from an edge of the gripping portion. The lid also includes a locking tab forming part of the reclosable flap, extending from the arcuate portion of the gripping portion, and which is able to engage a bottom side of the rim when the reclosable flap is in a closed position.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
- For the purpose of illustrating the invention, there is shown in the drawings a form that is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIG. 4 is a cross-sectional view of a portion of a container and a portion of a lid, according to the illustrated embodiment. - Aspects of the present invention provide a lid that can be used to cover a container (e.g., a beverage cup). The lid has a reclosable flap, such as a tear-back flap, which is designed to be pulled back by a user from an initial closed position. In an illustrative embodiment, the reclosable flap is able to be removably locked in the open position; for example, in some embodiments, a portion of the reclosable flap frictionally engages one or more projections or indentations on the lid. The reclosable flap is also able to be removably locked in a closed position, using a locking tab. In an illustrative example of the use of the locking tab, after a user has taken a sip of liquid from the container, the user can close the reclosable flap, securing the reclosable flap in the closed position.
