The container 110 is configured such that the flange 115 protrudes outward so as to form a strip shape while being adjacent to the sealing part on the upper sidewall 112, whereby the locking handles 125 are caught and held in a locked state.

As shown in FIG. 8, the conventional hermetically sealed container 110 covers the cover 120, and when the locking knob 30 is pushed downward, the locking knob 30 is a boundary portion 121 of the rectangular cover 120. ) And the locking projections 126 are coupled to the locking grooves 117 of the flange 115, respectively, to maintain the locked state of the container.

As shown in FIG. 9, in order to unlock the sealed container, holding the locking knob 30 and lifting it upward, the locking protrusion 126 of the locking knob 30 is locked out of the locking groove 117. The lock state of the handle 125 is released to open the cover 20.

However, the conventional hermetically sealed container is deformed so as to rotate based on the boundary of the locking knob regardless of the type of the contents contained in the container or the intended use, and the latching protrusion is applied to the locking groove of the flange to collectively cover the lid. It is configured to stay locked.

Therefore, the conventional hermetically sealed container is inconvenient in use because it repeatedly repeats the locking operation of the same lid irrespective of the type or use of the contents.

Furthermore, even if the contents are stored in a high frequency of use, or if the lid is to be covered for a while during use, the locking operation of the same lid is repeated, which causes inconvenience in use.

It is an object of the present invention to solve the problems as described above, to provide a double lock hermetically sealed container that can selectively adjust the locking state according to the type and use of the contents.

The double lock hermetically sealed container of the present invention for achieving the above object is a container in which a plurality of locking projections protrude outwardly adjacent to an open end side edge portion, and a locking handle corresponding to each locking protrusion extends to an edge portion. It includes a cover that is formed, the locking handle is a soft portion is formed adjacent to the edge of the lid, the locking projection is formed inside the end to hold the locking projection to maintain the primary locking state of the lid, the locking projection is inserted into the lid A locking hole is formed between the locking protrusion and the soft part so as to maintain the secondary locking state.

Here, the soft portion may be formed of a groove formed adjacent to the inner side along the edge of the lid.

The container has a flange protruding along the outer circumferential surface of the open side edge portion, and the locking projection may protrude from the flange. The flange may be provided with a reinforcing portion connecting the container wall to the lower portion where the locking projection is formed.

The locking protrusion may be formed in the bottom surface of the locking protrusion and the locking hole to maintain the locked state.

As described above, the double lock hermetically sealed container of the present invention maintains the primary locking state of the lid by the locking protrusion of the locking handle, and then maintains the secondary immersion state by the locking hole, thereby keeping the contents contained in the container. It has the effect of allowing more convenient use by adjusting the lock state according to the type and use of the.
