A container includes a container body; and a cap that locks onto the container body, the container body and the cap being locked by putting the cap on the container body. The cap includes a cap body, a cover cap being held on the cap body so as to be displaceable and rotatable, and an urging portion that upwardly urges the cover cap. When a rotational force is applied to the cover cap being downwardly pressed, the cap body is displaced in conjunction with the cover cap, so that locking between the cap body and the container body is released, and in a state where the cover cap is not downwardly pressed, the cap body is not displaced in conjunction with the cover cap even when a rotational force is applied to the cover cap, so that locking between the cap body and the container body is not released.

Closing system for bottles and small bottles and method for the use thereof for the opening of said bottles integrated by a single piece with three differentiated parts, two of them, inner threaded hole and screw (7), made of rigid material and joined by a pre-cut line, used as a base on which an elastic part (10) is overpressed. This elastic part (10) has some perimeter grooves (18) that, when fastening the screw (11) in the inner threaded hole (4) of the neck (3), presses the elastic part (10) and secures it against the walls of the bottleneck (3). The bottle can be opened by just lifting the covering half fins (9) and turning them in the opposite direction to the thread, so the elastic part (10) is decompressed and can be easily removed, leaving the bottle opened. All materials are food grade materials.

A closure element of the press-twist type for closing a container comprises: a capsule having a side wall extending about an axis, and a transverse panel extending transversely to said axis, an annular seal for sealingly engaging with a mouth of the container.

The annular seal is made of a PVC-free material and comprises: a side portion arranged in contact with the side wall of the capsule; a front portion extending from the side portion towards said axis; a deformability promoting element for increasing deformability of the front portion, the deformability promoting element comprising a recessed zone configured to be at least partially filled by the material forming the front portion when the front portion is pressed against an edge of the container delimiting the mouth.

A snap-on/twist off closure (22), a package comprising the closure, e.g., a bottle in combination with the closure is disclosed. The closure includes an upper wall defining an opening and a cylindrical snap on pipe (30) depending from the upper wall. The pipe includes threads designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess (42) and a guidance recess (70). A bottom rim of the pipe, the resistance recess and the guidance recess are in contact with a forcing element (50) on a shoulder of the bottle and guide the closure into positions permitting unscrewing of the closure

Closures are provided consisting of a lid or cap member and a container member. These are inter-engageable with one another. The lid or cap member has a skirt and the container member has an upstanding rim, each of which is of generally polygonal (preferably square) shape. Located on each of the facing walls on each side of the polygonal shape are inter-engageable projections. The inter-engaging surfaces of the projections run substantially in a plane perpendicular to the axis of the polygonal shape and are of relatively small angular extent about that axis. The material of one or both of the skirt and container portion is resiliently elastic. The closure may be assembled with an axial push, and removed by twisting.
