Lid for airtight container

Abstract

The present invention relates to a lid for use in an airtight container. The lid comprises a center section; a subsiding center section surrounding the center section and extending outwardly therefrom; a rim reinforcing section surrounding the subsiding section and extending outwardly therefrom; a lid rim surrounding the rim reinforcing section and extending outwardly therefrom, the lid rim being adapted to form a seal with a container rim defined on the airtight container; and at least two locking wings mounted on the lid rim adapted to engage with a wing connection part extending outwardly along an exterior of the container rim such that the lid defines a locked and unlocked configuration with respect to the container. The lid rim and the container rim form a spatial interval sized to allow for upward, downward and circular movement of the lid with respect to the container. The lid protrudes upwardly in a sectional configuration extending from the rim to the center section. As a result, a lid for use with an airtight container is provided that does not open involuntarily during involuntary fall or downward pressure is applied.

AI Technical Summary

Benefits of technology

[0018]In an exemplary embodiment, the center section of the container is formed in either a curved surface or plane. In a further embodiment, the subsiding center section is formed in a subsiding circular arc plane. The subsiding center section can be formed to completely surrounding the center section. Further still, the subsiding center section can be formed in separated interval sections surrounding the center section. In a further embodiment, the rim reinforcing section is formed in either a curved surface or a tilted plane. In an exemplary embodiment, the lid further comprises a handle having opposed ends bonded in boundaries between the subsiding center section and the center section for circular movement. The handle is accommodated in the subsiding center section. In an exemplary embodiment, the lid is constructed to make operable distribution of an external force applied to the lid from the lid to the rim reinforcing section and increasing a locking force formed by the locking wings.

Problems solved by technology

Although such salad bowl containers have been used in cooking, they typically have not been used for the purpose of storing food.

Using separate containers brings about several inconveniences such as needing additional and unnecessary containers and increasing the amount of containers to be washed.

A problem exists where the lids open with involuntary unlocking of the locking wing fastened to the wing connection part of the main body of the container when a user drops the airtight container or unintentionally applies downward pressure to the lid.
