The engagement mechanism is a mechanism in which a protrusion of a hook provided at the front end of the inner side surface of the lid and an engagement part provided at the front end of the container body engage with each other. The hook extends downward from the inner side surface of the lid and is formed at two walls arranged in parallel to each other, an inclined surface positioned between the two walls, and a tip of the inclined surface. The inclined surface is formed so as to extend obliquely downward from the front wall provided at the front end of the lid toward the inside of the thin container. At least one opening is provided. To.

  The opening is formed in a shape extending in a direction perpendicular to the wall, or the opening is provided in a connection portion between the two walls and the inclined surface, and the two openings are released at the tip side of the inclined surface. It is possible to make a slit shape, and it is also possible to partially reduce the thickness of the inclined surface.

  Further, by forming a further opening connecting the two slit-shaped openings to each other, the opening is formed in a substantially U-shape, and the inclined surface is formed by the opening formed in a substantially U-shape. A first part connected to the wall and the front wall and a second part formed with the convex part are separated by a support wall extending downward from the inner side surface of the lid. The structure is supported.

  The thin container of the present invention comprises a lid and a container body, and the lid and the container body are connected to each other by a hinge mechanism provided at each rear end, and fixed to each other by an engagement mechanism provided at each front end. The engagement mechanism is a mechanism in which a protrusion of a hook provided at the front end of the inner side surface of the lid and an engagement part provided at the front end of the container body engage with each other. The hook extends downward from the inner side surface of the lid and is formed at two walls arranged in parallel to each other, an inclined surface positioned between the two walls, and a tip of the inclined surface. The inclined surface is formed so as to extend obliquely downward from the front wall provided at the front end of the lid toward the inside of the thin container. Because at least one opening is provided. When opening and closing the lid, the hook is easily deformed to realize a smooth opening and closing operation, and it becomes difficult to cause stagnation, so that it is possible to reduce the opening and closing sound of the lid, and separate from the conventional container The manufacturing cost can be reduced by eliminating the need for the elastic member.

  Then, the shape of the opening is a shape extending in a direction orthogonal to the wall, or the opening is provided at a connection portion between the two walls and the inclined surface, and the two openings are inclined. By making the slit shape released at the front end side of the surface, or by forming a further opening that connects the two openings of the slit shape to each other, or by making it substantially U-shaped, or of the inclined surface By making a part of the thickness thinner, the hook can be more easily deformed, so that the lid can be opened and closed more smoothly, and the sound during opening and closing can be further reduced.
