Interlocking container

Abstract

The present invention relates to an interlocking container that has a wing provided on the exterior wall of a container body containing contents and fixes the other container body interlocked above the container body by means of the wing. The interlocking container includes a container body that includes a projecting portion bent downward, which is provided at the circumference of an exterior wall, a first groove grooved at an upper end of the projecting portion in a predetermined depth, and a hill portion that is provided at an entrance of the first groove and projects from an upper end of the projecting portion; a wing that includes a pair of hinges projecting at one side of the exterior wall, a support body hinge-coupled with the hinge, and a fixation projecting piece projecting on one end of the support body to form a predetermined angle to the support body, which fits in the first groove through the fixation projecting piece; and a cover that includes the projecting portion provided at the circumference of the exterior wall and the hill portion provided on the top surface of the projecting portion, which covers the upper part of the container body. According to the present invention, fastening force between interlocked containers is improved, contents stored in the container are prevented from being leaked to the outside, and a lifespan is also increased.

1 . An interlocking container, comprising:
 a first container body having walls defining an opening at a top surface, the first container body having a projecting portion provided proximate an outer surface of the walls and extending downward, a first groove provided at an upper end of the projecting portion, and a hill portion projecting upward from the upper end of the projecting portion and defining the first groove;   a wing having a pair of hinges projecting at one side of the exterior wall, a support body hinge coupled with the hinge, and a fixation projecting piece projecting on one end of the support body to form a predetermined angle with respect to the support body, the fixation projecting piece configured to be secured to a first groove of a second container body; and   a cover having a projecting portion provided proximate an edge of the cover and extending downward, a first groove provided at an upper end of the projecting portion, and a hill portion projecting upward from the upper end of the projecting portion and defining the first groove, the cover being configured to cover the opening of the first container body.   
   
   
       2 . The interlocking container according to  claim 1 , wherein the first container body includes:
 a second groove defined by the walls of the first container body and the projecting portion; and   a packing made of a flexible material provided within the second groove.   
   
   
       3 . The interlocking container according to  claim 1 , wherein the wing further includes a handle provided in the support body. 
   
   
       4 . The interlocking container according to  claim 1 , wherein the first container body further includes a joining fixation portion that connects the hinge formed on one surface of the first container body with the hinge formed on the other surface of the first container body in order to fix the container body. 
   
   
       5 . The interlocking container according to  claim 1 , wherein the interlocking container is molded by a plastic material and is transparent. 
   
   
       6 . The interlocking container according to  claim 1 , wherein the cover includes a grippable handle mounted on a top surface thereof. 
   
   
       7 . An interlocking container, comprising:
 a container body having a lip provided proximate an upper portion of the container body and and a bottom provided proximate a lower portion of the container body, the lip defining an opening of the container body, the bottom being configured to be inserted into an opening of another container body to be placed below the container body;   a wing provided proximate the upper portion of the container body and having a latch ; and   a projecting component provided proximate the lower portion of the container body, the projecting component having an upper groove and a lower groove, the upper groove being configured to receive a latch of a wing of the another container body to be placed below the container body, the lower groove having an elastic material therein to receive a lip of the another container body to be placed below the container body.   
   
   
       8 . The interlocking container of  claim 7 , wherein the bottom of the container body has length and width that are smaller than length and width of the opening of the another container body. 
   
   
       9 . The interlocking container of  claim 7 , wherein the opening of the container body is configured to receive a bottom of another container body to be placed on top of the container body, and
 wherein the latch of the wing of the container body is configured to be secured to an upper groove of the another container body to be placed on top of the container body.   
   
   
       10 . The interlocking container of  claim 7 , wherein the latch of the of the wing of the container body is configured to be secured to a groove of a lid to securely enclose the opening of the container body with the lid.
