Storage container

Abstract

A storage container is disclosed. A storage container according to one aspect of the present invention comprises: a cover; and a container body, wherein the cover is provided with a locking wing on one side thereof so as to be rotatable, wherein the container body is provided with an edge which protrudes on a side surface thereof, wherein an edge end portion is formed at the edge, wherein the edge end portion has an upper engaging groove and a lower engaging surface, wherein one side of the upper engaging groove is open, wherein the cover is provided with a side surface protrusion which is engaged with the lower engaging surface when the cover is coupled to the container body, and with an engaging protrusion which is inserted into the upper engaging groove when the cover is separated from the container body.

1 . A storage container comprising:
 a cover and a container body,   wherein the cover comprises a locking flap on one side thereof, the locking flap having a rotatable configuration,   the container body comprises a rim protruding from a side surface thereof,   the rim has at least one pair of rim end portions formed therein, the pair of rim end portions facing each other,   the rim end portion comprises an upper latching indentation and a lower latching surface,   the upper latching indentation is open at one side, the cover comprises a side protrusion configured to latch onto the lower latching surface when coupled onto the container body,   and the locking flap is inserted into the upper latching indentation when separated from the container body.   
     
     
         2 . The storage container of  claim 1 , wherein the rim end portions are arranged as a pair facing each other with a movement space of a particular distance therebetween. 
     
     
         3 . The storage container of  claim 1 , wherein the upper latching indentation has an upper inclined surface formed therein. 
     
     
         4 . A cover for a storage container configured to couple with a container body of the storage container, the cover comprising:
 a first inner rim and a second inner rim arranged at an inward side of the first inner rim, the first inner rim and the second inner rim arranged with a particular gap in-between to form a packing groove,   wherein the second inner rim comprises a front rim and a rear rim, the front rim formed at a side where a locking flap is provided, the rear rim arranged opposite the front rim,   and the front rim and/or the rear rim is formed such that a lower end portion thereof is positioned flush with or lower than an upper end portion of the container body when the cover is coupled to the container body.   
     
     
         5 . A cover for a storage container configured to couple with a container body of the storage container, the cover comprising:
 a side protrusion; and   a first inner rim and a second inner rim arranged at an inward side of the first inner rim, the first inner rim and the second inner rim arranged with a particular gap in-between to form a packing groove,   wherein the side protrusion comprises a side inclined surface having a sloped angle,   and the second inner rim comprises a rim inclined portion having a sloped angle less steep than the side inclined surface.   
     
     
         6 . A cover for a storage container configured to couple with a container body of the storage container, the cover comprising:
 a packing;   a packing groove configured to receive the packing inserted therein;   an air channel formed intagliated in the packing groove to enable an inflow and outflow of air; and   an adjustment protrusion formed in the air channel and configured to contact the packing,   wherein, while the cover and the container body are coupled to maintain a sealed state, a contact between the adjustment protrusion and the packing is temporarily disengaged by a pressure difference between an inside and an outside of the storage container such that an inflow or outflow of air is permitted.   
     
     
         7 . The cover for a storage container according to  claim 6 , wherein the adjustment protrusion protrudes to an outside of the air channel. 
     
     
         8 . A cover for a storage container configured to couple with a container body of the storage container, the cover comprising:
 a packing;   a packing groove having a bottom surface and configured to receive the packing inserted therein;   an inner protrusion formed protruding from the bottom surface and forming an air channel to enable an inflow and outflow of air between the bottom surface and the packing; and   an adjustment protrusion formed on one side of the inner protrusion and configured to close the air channel by contacting the packing,   wherein, while the cover and the container body are coupled to maintain a sealed state, a contact between the adjustment protrusion and the packing is temporarily disengaged by a pressure difference between an inside and an outside of the storage container such that an inflow or outflow of air is permitted through the air channel.   
     
     
         9 . The cover for a storage container according to  claim 6 , wherein the packing comprises a hollow cavity. 
     
     
         10 . The cover for a storage container according to  claim 9 , wherein the adjustment protrusion is formed in a same direction as a lengthwise direction of the hollow cavity when the packing is inserted in the packing groove. 
     
     
         11 . The cover for a storage container according to  claim 6 , wherein the cover comprises a downwardly protruding support protrusion, the support protrusion configured to prevent the air channel from being closed off completely by an excessive contraction of the packing. 
     
     
         12 . The cover for a storage container according to  claim 7 , wherein the packing comprises a hollow cavity. 
     
     
         13 . The cover for a storage container according to  claim 8 , wherein the packing comprises a hollow cavity. 
     
     
         14 . The cover for a storage container according to  claim 12 , wherein the adjustment protrusion is formed in a same direction as a lengthwise direction of the hollow cavity when the packing is inserted in the packing groove. 
     
     
         15 . The cover for a storage container according to  claim 13 , wherein the adjustment protrusion is formed in a same direction as a lengthwise direction of the hollow cavity when the packing is inserted in the packing groove. 
     
     
         16 . The cover for a storage container according to  claim 8 , wherein the cover comprises a downwardly protruding support protrusion, the support protrusion configured to prevent the air channel from being closed off completely by an excessive contraction of the packing.
