When the cover 28 is in the closed position, the cover is closed. The bump 58 is compressed against the body 22. In detail, the cap bump 58 is compressed against the circular tab 48 of the throat 38, and the compression of the cap projection 58 is between the cover 28 and the body 22. An opening force is applied which acts on the vicinity of the hinge 34.

Referring to FIG. 9, when the latch 32 is in the release position, as shown in FIG. 2, the user presses the forwardly projecting portion 114 to compress the elastic member 108 so that the latch 32 is in the latch chute. In 52, the movement of the latch 32 causes the hook tab 44 to disengage from the collar 26. The position shown is the result of the continuous compression of the latch 32. Once the user releases the pressing force, the pressure is currently pressed. The resilient member 108 will spring open, causing the latch 32 to return to the locked position.

The one shown in Fig. 9 is in an instantaneous state because the latch 32 causes the pressed spring cover bump 58 to apply an opening force to the cover portion 28 to cause the cover portion 28 to move away from the locked position. In the preferred embodiment, the latch The lock 32 is pressed to release the poppet bump 58 which causes the cover portion 28 to "bounce" to a slightly open position, in which the hook tab 44 is no longer engaged with the collar 26 opening, thus The lid portion 28 will not be locked again, after which the user can pry the lid portion 28 to the fully open position to place the food product in the container or to remove the food product from the container. When the lid portion 28 is raised to a slightly open position, The user can flip the unlocked lid 28 to the open position with a single hand, thereby allowing the user to easily open the container even if the hands are inconvenient.

The manner in which the food storage container 20 of the present invention is closed is also simple. After the food is placed in the container, the lid portion 28 can be turned to the closed position. If the lid portion 28 is not biased to close, the lid projection 58 can maintain the lid portion 28 in an unlocked position. When the closing force is applied to the portion 28, the cap projection 58 is compressed, so that the hook end 112 of the hook tab 44 slides on the collar portion 26 (the edge can also be a tapered structure), and the latch 32 is temporarily moved. In the release position, after the pressure applied by the cover portion 28 causes the hook end 112 on the hook tab 44 to pass the collar edge, the compressive elastic force stored by the elastic member 108 forces the latch member 32 to return to the lock. In position, the hook end 112 of the hook tab 44 is coupled to the collar 26, thereby locking the lid portion 28, and the lid portion 28 in the closed position causes the inside of the washer 88 to be abutted by the projection 40 of the lid portion 28. compression.
