A head (10) of a trigger dispensing device (1) for liquids includes a pre-compression valve (104) disposed in the upper region of the head. The valve (104) has an obturator wall (106) that cooperates with a mouth wall (102) to prevent the passage of liquid. The mouth wall (102) includes a sealing section (102a) with which the obturator wall (106) is sealingly engaged to slide during a pre-compression step of the liquid.

To further improve a dispenser of the type in question, in particular with regard to an advantageous production, it is proposed for the support on the inner surface of the cap part to be formed by means of a support section of the support part, which protrudes below the sealing zone and which simultaneously forms an accommodation for the upper free edge of the bellows part in a one-part embodiment with an accommodating section. Provision can thus be made for a one-part embodiment of the support part.

A dispenser for discharging liquid to pasty masses, has a pump head and a pump chamber, having a pump chamber wall and an inlet valve and an outlet valve. The pump chamber is formed by a bellows part, on which the inlet valve is integrally formed. The inlet valve is retained of retaining arms, which extend in the peripheral direction of the inlet valve and are connected to the pump chamber wall and to the inlet valve, and the inlet valve forms a peripherally extending valve lip, which freely protrudes in cross-section. The inlet valve extends in the shape of a circle segment in a longitudinal cross-section of the bellows part, having an upper dome segment and the lower valve lip. The connection to the retaining arms is formed at a height center of the inlet valve or at an offset therefrom toward a free edge of the valve lip.

A dispenser device for a container containing a product to be dispensed, the device comprising a body for connecting to the container and presenting a chamber that is open at a bottom end of the body and in which a pump is arranged, connected to a top dispenser head. The dispenser device also comprises a driver that is suitable for being moved so as to cause the dispenser head to move between a storage position in which the dispenser head is substantially retracted inside the body, and a dispensing position in which the dispenser head projects beyond a top end of the body. The dispenser device further comprises a sealing diaphragm that defines a top end of the chamber and that presents a movable end that is connected to the pump, and a stationary end that is suitable for being connected to the container.

A discharging device for liquids. The invention relates to a discharging device for liquids, more particularly for pharmaceutical liquids, comprising a delivery device (10), a liquid storage receptical (20) communicating with an input (10a) of the delivery device for storage of the liquid (30), and a discharge orifice (12) which communicates with an outlet (10b) of said delivery device, and the liquid storage receptical (20) is at least in part in the form of a dimensionally flexible liquid-containing bag (20) and the liquid storage receptical (20) is disposed in a buffer chamber of constant volume (42). To prevent air from escaping from the buffer chamber (42), provision is made for the buffer chamber to be sealed by a protective housing from the environment (1) in a gas-tight manner, for the buffer chamber to communicate with the environment through at least one capillary passageway for the purpose of pressure compensation, or for the buffer chamber (42) to communicate with the environment (1) via a balancing passageway for the purpose of pressure compensation, while a valve (70) which opens in dependence on the pressure differential is disposed in this balancing passageway.

A dispenser system including a first dispenser module having a medium chamber fillable with medium, a first discharge head actuable for discharging medium from the medium chamber, a refilling opening, and a second dispenser module coupleable to the first dispenser module for refilling the latter. The second dispenser module has a storage container for medium, and a second discharge head. In the decoupled state of the dispenser modules, the second discharge head is actuable for discharging the medium out of the storage container and has a discharge opening. The second discharge head has a ventilation system for equalizing the pressure in the storage container when the medium is discharged. The dispenser system has an air pump system. In the coupled state of the dispenser modules, the air pump system is fluidly coupled to the ventilation system and conveys air via the ventilation system into the storage container.

Dispenser pump for pumping reservoir fluid to a dispenser head, has a dip tube to insert into the fluid, a cylinder housing connected with the dip tube, a piston pipe guided in longitudinal direction by the cylinder housing for pumping the fluid from the dip tube to the dispenser head, wherein the piston pipe comprises a connecting area for connecting the dispenser head to the piston pipe, a top part connected with the piston pipe, a bottom part connected with the cylinder housing and a spring bellow for pushing the piston pipe in a direction outwards the cylinder housing, wherein a lower axial end of the spring bellow is connected with the bottom part via a lower retainer ring located inside the spring bellow and/or a higher axial end of the spring bellow is connected with the top part via a higher retainer ring located inside the spring bellow.

A head (10) of a trigger dispenser device includes a bulb (70) having an elastically deformable casing (72) that includes a vent lip (90), molded in one piece. With the casing (72), the vent lip (90) forms a venting valve.

Cosmetic products, comprising a container having a tubular body, the wall of which has a transmission for visible light of from 25 to about 100%, and on the top end of which a dispenser head is attached, the dispenser head being bounded below by a movable trailing piston, and a cosmetic preparation in the interior of the container which preparation comprises an outer flowable water-based gel-type phase having a transmission for light of 700 nm wavelength of from 30 to 100% and/or a viscosity of 1000-10,000 mPas at a temperature of 25 C. and a shear rate of approximately 10, and an inner solid particulate phase which comprises substantially spherical particles having an average diameter of from 0.1 to 10 mm, the volume ratio of the inner particulate phase to the outer aqueous gel ranging from about 20%:80% to 74%:26%.

A head (10) of a trigger dispensing device (1) for liquids includes a pre-compression valve (104) disposed in the upper region of the head. The valve (104) has an obturator wall (106) that cooperates with a mouth wall (102) to prevent the passage of liquid. The mouth wall (102) includes a sealing section (102a) with which the obturator wall (106) is sealingly engaged to slide during a pre-compression step of the liquid.
