Abstract: Low height precompression pump. The pump comprises: a cylinder (1) comprising a pump chamber (3), and an inlet valve (5), a piston (7) with a lower outwardly flaring lip seal (9) and an inwardly flaring lip seal (19), which rims a central aperture (17) of the piston (7), a hollow pump plunger rod (21), which is in sliding engagement with the central aperture (17), and which has a passage for communication (23) between the pump chamber (3) and the exterior, a securement device (37), with an upper retention cover (39), which attaches the cylinder (1) to a container, a first elastic member (31) housed in the cylinder (1) and a second elastic member (47), which has an upper bearing point (49) applied directly on the plunger rod (21), and which is above the upper retention cover (39).

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 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.

Abstract: A cap (1) for a bottle stopping device, where the device comprises a main body member (9) and the cap (1), where the cap (1) is adapted to be mounted on the main body member (9) and thereby defines a mounted position, the main body member having (9) retaining tabs (21), the cap (1) having a side wall (5) for pressing the tabs (21) against the bottle neck, where the side wall (5) has an upper portion (7) and a lower portion (11), where the side wall (5) is provided at the lower portion (11) with an end portion (15) folded back 180° over itself towards the inside, in such a way as to define an internal shoulder for retaining the tabs (21).
