Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a one-touch opening/closing mechanism for containers, particularly those with a double structure, such as compact containers.

In recent years, lower containers have been installed on the bottom side of containers with storage recesses.
A container such as a compact with a double structure in which lids are connected to the upper surface side by hinges so that they can be opened and closed has been proposed, but in this case, locking means such as hooks are provided protruding from the periphery of each part.
This engagement closes the container, the lower container, and the lid, and when opening the container, a strong force is required to release the engagement, which not only risks damage, but also causes damage to the upper and lower containers. The opening operation for the lower container must be performed separately.

There were drawbacks such as the troublesome opening operation.

Particularly in this type of double structure, it has not been possible to simultaneously open both the container and the lower container with a one-touch operation.

In view of the above, the present invention has been proposed, in which a lower container and a lid are connected to the container by a hinge so that they can be opened and closed, and a locking means is provided for the container, the lower container, and the lid to engage with each other when the container is closed. As an opening/closing mechanism for containers such as heavy-duty compacts, it is designed to be able to open and close both the container and lower container at the same time with a simple one-touch operation, and to be simple in structure and easy to manufacture at low cost. A notched recess that opens vertically and outwardly is provided in the peripheral edge, a slide hole is provided inwardly on the inner surface of the notched recess, and engaging steps are provided on both sides of the inner part, and the slide hole is An opening operating member having a finger rest that fits into the notched recess on the waist and a pair of insertion pieces that are arranged opposite each other at a required interval on both sides of the inner surface so as to be fit into the slide hole. The insertion piece is inserted so as to be able to move forward and backward, and the locking claw provided on the outside of the tip of the insertion piece is latched to the engagement step part when the opening operation member is in the extended state, so that the opening operation member is inserted into the container. In addition, the upper and lower finger rests of the opening operating member and the peripheral edges of the lid body and lower container that face the opening operating member have slopes that can be pressed into contact with each other by the pushing and retracting action of the opening operating member. A surface is provided so that the engagement of the locking means between the container and the lid and the lower container is disengaged by this pressing, and guide protrusions are provided oppositely on both left and right sides of the notch recess to prevent the opening operation member from engaging with the locking means. A notch that fits into the guide protrusion is provided on both sides of the inner surface of the finger rest,
This is characterized in that the opening operating member is prevented from swinging in the vertical direction within the notched recess.

Next, embodiments of the present invention will be described based on the drawings.
