Claims (1)

[Scope of utility model registration request] As the neck shape of the container body hangs down in the direction below the mouth, an overhanging stepped portion is formed which is cut approximately horizontally from the overhanging top surface portion toward the axis, and is spaced apart from it in the circumferential direction. As the part hangs down, it becomes a gouged part in the shape of a reverse taper, and at the base of the neck, the entire circumference becomes a constricted part with a smaller diameter than the upper part, and from the neck, through the shoulders, to the torso. The cap consists of an inner tube that covers the neck of the container body, an outer tube, a ceiling, connecting ribs, fitting ribs, etc.; It consists of a lock body that is assembled at the top, and by moving the lock body in a circular motion, the pressure plate provided below the lock body fits into the gap between the inner cylindrical part of the cap body and the fitting rib, and then fits into the neck of the container body. A small container having a cap with an improved locking function, characterized by a structure that prevents the lower part of the fitted inner cylinder from expanding outward or presses the lower part of the inner cylinder in the radial direction.
