Abstract: An automatically closing dispenser stopper applicable to deformable containers for liquids, the stopper being constructed of plastic material and dispensing the liquid when the container is squeezed or deformed with the stopper facing downwards, the stopper closing automatically to form a seal when the compression exerted on the outside of the container ceases, this the tending to elastically recover its initial shape to put the liquid contained in it under vacuum and hence cause the stopper to close automatically.

Abstract: A pasty or creamy substance dispenser comprising a bottle having a cylindrical chamber for containing a substance to be dispensed, and an elastically deformable cap mounted on the bottle and defining a compression chamber for the substance with an elastically deformable wall formed integrally with the bottle, the cylindrical chamber of which is closed by a piston movable under sealed conditions.

Abstract: A cap with a rotatable skirt (1), applicable to the mouth (6) of a container (7) for a fluid dispensable via the cap, which can also act as a closure cap. The cap comprises a skirt (1) rotatable on the mouth (6) of the container (7) and defines a cavity housing a hollow body (2) connected to the skirt (1) by breakable teeth (4), the skirt (1) and the hollow body (2) being formed in one piece by moulding. Between the skirt (1) and the hollow body (2) there extends an axially translatable cup-shaped body (3) connected to the skirt (1) by a disc (19) housed in a seat (21) provided on the top of the skirt (1), this disc (19) being moulded in one piece with the cup-shaped body (3), to which it is connected by breakable teeth (20).
