Abstract: A cap for a bottle stopping device to be mounted on a main body member. The main body member has retaining tabs, and the cap has a side wall for pressing the tabs against the bottle neck. The side wall has an upper portion, and a lower portion provided with an end portion folded back 180° over itself towards the inside, in such a way as to define an internal shoulder for retaining the tabs.

Abstract: A pump having a decompression device, appropriate for pumping a fluid from a container to an external environment, the pump including a jacket defining an inner space, a pumping chamber (17) housed in the inner space a piston for movement within the inner space between an extended position and a retracted position, and a decompression device which, when the piston is in the retracted position, places the pumping chamber in communication with a conduit communicating with the external environment.

Abstract: A liquid spray pump comprising: [a] a jacket (1), defining a longitudinal axis (7), [b] a piston (3), for being inserted, at least partially, in the jacket (1), and adapted for being moved in the direction of the longitudinal axis (7) along the jacket (1), [c] at least one annular lip (15), surrounding a section of the piston (3) perpendicular to the longitudinal axis (7), [d] a hollow internal space (17) defined between the jacket (1) and the piston (3), and [e] at least one shoulder (19) on the piston (3) occupying at least in part the hollow internal space (17).

Abstract: Device for closing bottles having a neck with an outer annular edge and including: a) a main body comprising an annular part having an outer edge area and tongues jointed to the outer edge area of the annular part, in addition to an inner surface, and outer surface, lateral surfaces and a lower surface in which the tongues have two first ribs standing out form the inner surface and adjacent to the lateral surfaces and the outer surface has a raised area and b) a sleeve with a substantially hollow and cylindrical part, wherein the substantially cylindrical part can be placed on the tongues.
