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.

1 . A lid for use in an airtight container comprising:
 (a) a center section;   (b) a subsiding center section surrounding the center section and extending outwardly therefrom;   (c) a rim reinforcing section surrounding the subsiding section and extending outwardly therefrom;   (d) 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;   (e) 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;   wherein 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; and   wherein the lid protrudes upwardly in a sectional configuration extending from the rim to the center section.   
   
   
       2 . The lid of  claim 1 , wherein the center section of the container is formed in either a curved surface or plane surface. 
   
   
       3 . The apparatus of  claim 1 , wherein the subsiding center section is formed in a subsiding circular arc plane. 
   
   
       4 . The apparatus of  claim 1 , wherein the subsiding center section is formed to completely surround the center section. 
   
   
       5 . The apparatus of  claim 4 , wherein the subsiding center section is formed in separated interval sections surrounding the center section. 
   
   
       6 . The apparatus of  claim 1 , wherein the rim reinforcing section is formed in either a curved surface of titled plane. 
   
   
       7 . The apparatus of  claim 1 , further comprising a handle having opposed ends bonded in boundaries between the subsiding center section and the center section for circular movement, wherein the handle is accommodated in the subsiding center section. 
   
   
       8 . The apparatus of  claim 1 , wherein 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. 
   
   
       9 . The apparatus of  claim 1 , wherein the lid further comprises a handle having opposed ends positioned in the center subsiding section. 
   
   
       10 . The apparatus of  claim 9 , wherein the handle is positioned in the center subsiding section operable to allow for circular movement of the handle within the center subsiding section. 
   
   
       11 . A storage unit comprising the lid according to  claim 1  and a container. 
   
   
       12 . The storage unit of  claim 11 , further comprising a plurality of nested containers, wherein the lid is adapted to enclose the plurality of nested containers. 
   
   
       13 . A storage system comprising a plurality of nested storage units according to  claim 11 .
