A dispenser head (10) of a trigger dispenser device includes a self-bearing pre-compression valve (80), made of polypropylene, capable of per se retaining in a stable manner to the head frame (14).

A dispensing head for a system for dispensing a product is described herein. The head includes a body having a housing that is provided with an anvil around which a nozzle is mounted. The nozzle includes an outlet orifice to place the housing in communication with the exterior, and wherein the head includes a membrane added around the periphery of the anvil in the housing in such a way as to form between the membrane and the nozzle a path for dispensing the product.

The invention concerns a device (1) for dispensing a fluid (L), comprising a supporting structure (2) provided with means (3) for coupling it with a container (C) holding the fluid (L) and comprising: an outlet duct (63) for the fluid (L); a collapsible chamber (60); first valve means (25) suited to control the passage of the fluid; air refilling valve means. The air refilling valve means comprise a flexible portion (15) of an edge (14) belonging to a first element (10) of the device (1), suited to assume a closed position and an open position. The invention concerns also a system comprising a container and a device made as described above.

A trigger pump dispenser comprises a body, an outlet nozzle, a pump chamber, a piston for defining a variable volume in the pump chamber, a trigger coupled with the piston by interconnection means, and biasing means for biasing the trigger to a retracted position. The trigger is movable to cause the piston to pump liquid into and out of the pump chamber for dispensing through the outlet nozzle. The piston is interchangeably associatable with the trigger and the pump chamber so that different length pistons are usable to determine different maximum fill volumes of the pump chamber.

A valve assembly with a valve member coaxially received within a valve casing and interacts with the casing to provide a one-way inlet valve at one end of the valve casing and a one-way outlet valve at the other end of the casing with an annular compartment therebetween adapted to be coupled to a variable volume compartment and thereby together provide a simplified construction for valving components of a fluid pump.

The invention relates to a dosing device designed to equip a container including a deformable reservoir containing a product. The device includes an insert that includes a dosing chamber that can be deformed by pressure from the product coming from the reservoir. The dosing chamber includes a top valve for the intake of the product from the reservoir, a bottom valve dispensing the product, and a deformable body connecting the top valve and the bottom valve. The dosing chamber is configured such that, under pressure from the product coming from the reservoir, the top valve is closed by the deformation of a first portion of the chamber, the bottom valve remaining closed, whereupon, the bottom valve opens under the effect of the deformation of the body.

A liquid-dispensing device including a cap for protecting a liquid-dispensing opening, the protective cap being provided with a pad for absorbing residual liquid, made of an absorbent material, the absorbent pad being fastened to a support made of a more resistant material than the absorbent pad, the support being furthermore fastened in the protective cap.

A manually operable head assembly for a dispenser for pasty products which has a fixed head with a dispensing duct for dispensing a product, a pumping unit with an elastically deformable cap, an actuator, a guarantee tab connected to the fixed head and having a tab body, and at least one bridge connected to the actuator is provided. The at least one bridge is suitable for breaking on a first operation of the actuator. The tab body is configured to remain connected to the fixed head following the first operation of the actuator.

A spray head (10) for a device for dispensing a fluid product, comprising a body (11) provided with a spray hole (12), the spray head (10) comprising a connecting member (15) rigidly attached to the body (11), the connecting member (15) defining a central axial channel (16), the spray head (10) comprising at least one valve (20; 40) forming precompression means for generating a calibrated spray through the spray hole (12), an intermediate member (14) being inserted between the connecting member (15) and the body (11), the intermediate member (14) being hollow and comprising an opening (14) that opens into the connecting member (15), a sleeve (40) being mounted so as to slide in the connecting member (15) around the intermediate member (14) between an open position and a closed position, a resilient element (41) biasing the sleeve (14) to its closed position in which it closes off the opening (14), the sleeve (40) being moved towards its open position when the flow of fluid product (F) is actuated based on a predetermined pressure.

A massage applicator for massaging cream-type fluids into the skin, provided with an end wall with a massage region, on which massage elevations are provided. The end wall is penetrated by at least one outlet channel for the cream-type fluid. The massage applicator is provided with suitable markings in the massage region for measuring the fluid to be used, the applicator is provided with a cover which can be blocked in an open position and/or secured in a closed position, and an assembly of two valves is used in order to secure against unintentional discharge.
