A quick-release positioning member, including a fixing portion, a first elastic portion, and a second elastic portion, is provided. The fixing portion is adapted to fix the quick-release positioning member to an object. The first elastic portion is connected to a first side of the fixing portion, extends toward a first direction, and has a first bending area protruding away from the fixing portion. The second elastic portion is connected to a second side of the fixing portion, extends toward a second direction, and has a second blocking area protruding toward the fixing portion. The first and second elastic portions are adapted to be deformed upon exertion of force. The first elastic portion is adapted to move in a third direction. The second elastic portion is adapted to move in the second direction. The first, second, and third directions are substantially orthogonal. An openable and closable device is also provided.

A card storage box is disclosed. The card storage box includes a housing having a cavity, where the housing is provided with an opening at a top, a clamping plate is slidably connected to a side wall of the housing and partially extends out of the opening, a card pushing member is rotatably connected to the housing and positioned at a bottom of the cavity. The card storage box further includes a cover body, where the cover body is rotatably connected to the housing, and the cover body can cover the opening. A limiting groove is provided in an inner wall of the cover body, when the cover body covers the housing, the clamping plate is clamped with the limiting groove, and the clamping plate abuts against a groove wall of the limiting groove to limit a rotation of the cover body.

A package for a powdered nutritional product comprises a container for receiving the nutritional product, having a base and a peripheral wall. A lid assembly comprises a circumferential rim, defining an access opening, for connection to the container and a lid, pivotably attached to the rim by at least one hinge having a hinge axis. The lid has an open position and a closed position in which it closes the access opening. The hinge comprises a rim portion, integral with the rim, and a lid portion, integral with the lid, that can be engaged to each other to join the lid to the rim. The hinge is are arranged such that the lid portion can only be engaged with the rim portion in the open position of the lid. In the closed position of the lid, the lid portion is locked to the rim portion, preventing separation of the lid portion from the rim portion. The hinge is also arranged to prevent opening of the lid beyond a point at which the package is unstable.

A hinge structure includes: a lower member which is to be attached to a container; an upper member which is to be attached to a lid; a rotary shaft connecting the lower member and the upper member to each other; and a link mechanism connecting the lower member and the upper member to each other at a position different from the position of the rotary shaft. The link mechanism includes a plurality of links pivotably connected to each other, and a spring mechanism of a torsion coil type configured to give spring force to the upper member in a direction in which the lid is opened.

The fastener container in the present invention includes a lid and a receptacle base as main components combined together. Said lid has a first section and a second section which are connected by a hinge. This invention used the first prominent portion with flexible cushioning effect and the pressing member of the first prominent portion of the first section, and the blocking member and the third recess of the second prominent portion of the second section to reduce the wear and tear between the pressing member and the blocking member, it also can prevent the pressing member from squeezing the blocking member for a long time to result in a problem that the pressing member and the blocking member are deformed and the first section can not be held in the open position, so that the service life of the lid can be extended and the user can easily open or close the first section of the lid to take or place screws or other items.
