Problems solved by technology

However, one of the shortcomings of the prior art seals is that they leave too much air or head space within the container if the foodstuff contents occupy a space smaller than the size of the container.
They cannot conform to the shape of the foodstuff contents inside the container,

Embodiment Construction

[0022]Referring now to the drawings, and more specifically FIGS. 1 to 3, wherein the showings are for the purpose of illustrating the preferred embodiment of the invention only and not for the purpose of limiting the same, a container 10 preferably formed of rigid plastic material and a reusable flexible seal 12 each having a generally rectangular shape and configuration are illustrated. It is noted that other shapes and configurations such as, but not limited to, square, oval, triangular or circular-shaped container and seal are also contemplated to be within the scope of the present invention.

[0023]The container 10 includes a pair of longer sidewalls 14, a pair of shorter sidewalls 16, a bottom 18, and an upper peripheral edge 20 bounding a top opening 22 which provides access within a storage area 24 of the container 10.

[0024]The upper peripheral edge 20 of the container 10 includes a flat upper sealing surface 26 and a downwardly extending annular leg 28 having an engaging tip 3...

Abstract

A reusable flexible seal is disclosed having a flexible main portion and a peripheral ring surrounding the flexible main portion adapted to engage the rim of a container. The flexible main portion includes an upper surface, a lower surface, and is dimensioned and configured to generally eliminate the head space over the contents of the container when assembled on the container. A venting mechanism includes at least one tab member extending inwardly from the peripheral ring for creating a gap between the lower surface of a portion of the peripheral ring and the upper surface of a portion of the edge of container wall.

Description

TECHNICAL FIELD[0001]The present invention is broadly concerned with durable long-lasting reusable container seals, and more particularly, concerned with a reusable flexible container seal adapted to conform to the shape of the foodstuff contents of the container and to provide an air-tight seal for enhanced conservation of food quality.BACKGROUND OF THE INVENTION[0002]Prior art container seals, such as thermoplastic lids and flexible film covers, have been commonly used to hermetically seal the container to preserve the foodstuff contents such as meat, fish, and vegetables while stored in a freezer.[0003]However, one of the shortcomings of the prior art seals is that they leave too much air or head space within the container if the foodstuff contents occupy a space smaller than the size of the container. They cannot conform to the shape of the foodstuff contents inside the container, which will result in longer freezing time of the foodstuff and lowered food quality.[0004]Another s...
