  • Patent number: 11267620
    Abstract: A press type sealable container includes a housing including an open-top wall structure defining a receptacle for receiving material to be stored; a cover designed to fit over the opening of the container and have a movable push-push type button. According to the disclosure, a toggle mechanism is used instead of a self-locking push switch in the press type sealable container, thereby enhancing the resistance to pressure of the press type sealable container and improving the durability of the overall structure. Accordingly, the technical problems of unsatisfactory holding strength, easy damage under excessive pressure exerted by the push-push type button and short service life are solved. Moreover, the toggle mechanism is simple to implement, good in reliability, and long in service life.
