Container device with tightly engaged cover

Abstract

A container device with a tightly engaged cover comprises a container; each of at least two lateral walls having a buckling recess; a cover; each of at least two sides of the cover being formed with downward buckling plate; an inner side of each buckling plate having at least one buckle; an upper side of one end of the buckle having a buckling block. When the cover covers upon the container, the buckling plates of the cover will be expanded so that the cover covers the container. The buckles of the buckling plates of the cover will align to and enter into the buckling recesses of the container so that the buckles move downwards through a length; and thus the buckling blocks of the buckles will engage in the buckling recesses of the container; and the container is engaged with the cover by horizontal insertion and buckling effect.

What is claimed is: 
     
         1 . A container device with a tightly engaged cover comprising:
 a container; each of at least two lateral walls having a buckling recess;   a cover; each of at least two sides of the cover being formed with downward buckling plate; an inner side of each buckling plate having at least one buckle; an upper side of one end of the buckle having a buckling block;   wherein when the cover covers upon the container, the buckling plates of the cover will be expanded so that the cover covers the container; the buckles of the buckling plates of the cover will align to and enter into the buckling recesses of the container so that the buckles move downwards through a length; and thus the buckling blocks of the buckles will engage in the buckling recesses of the container; and the container is engaged with the cover by horizontal insertion and buckling effect.   
     
     
         2 . The container device with a tightly engaged cover as claimed in  claim 1 , wherein a buckling recess do not penetrate through a wall of the container. 
     
     
         3 . The container device with a tightly engaged cover as claimed in  claim 1 , wherein an inner diameter of the buckling recess is smaller than the sum of one diameter of the buckle and the buckling blocks at two sides of the buckle. 
     
     
         4 . The container device with a tightly engaged cover as claimed in  claim 1 , wherein the cover is installed with a handle. 
     
     
         5 . The container device with a tightly engaged cover as claimed in  claim 4 , wherein the handle and the cover are separately formed, the cover has at least two buckling holes for receiving two ends of the handle. 
     
     
         6 . The container device with a tightly engaged cover as claimed in  claim 1 , wherein an outer side of the buckling hole is formed with an inclined surface for resisting against an upper side of a distal end of the handle. 
     
     
         7 . The container device with a tightly engaged cover as claimed in  claim 1 , wherein an inner side of the buckling hole is a vertical resisting portion for resisting against a block protruded from a lower side of the distal end of the handle; and the block is a triangular block.
