Guala Dispensing S.P.A.

A trigger dispensing head of a trigger dispensing device is provided. The trigger dispensing head has a cylinder chamber, a piston, a pressure chamber, a sleeve having an end wall, a suction duct terminating in a suction mouth, a dispensing duct, and valve members for regulating flow of a product. The valve members have a valve element made in one piece. The valve element has a tubular portion, a flexible flap, and an annular membrane.

A disposable refill cartridge for releasing a product into a bottle has a single-chamber container having a breakable film, a connector screwable to the bottle, and a slider accommodated in a sliding manner in the connector.

A trigger head for a dispensing device for a liquid product that is usable an “upright” configuration and an “upside down” configuration has an attachment having an attachment suction chamber, a multifunction chamber and an auxiliary passage. The trigger head has multifunction valves operating in the multifunction chamber, which, in the “upright” configuration, close a communication between the multifunction chamber and a bottle compartment of a bottle of the dispensing device and, in the “upside down” configuration, close a communication between a multifunction passage of the multifunction chamber and a venting conduit of the trigger head.

A main valve body of a trigger dispensing head is made in one piece and has a substantially flat body base, an annular inner body wall, a shutter, an annular dispensing lip, a dispensing passage, and an outer body wall for protecting the annular dispensing lip.

A trigger dispensing head applicable to a bottle of a trigger dispensing device is provided. The trigger dispensing head has a cylinder chamber, a main vent passageway, a sleeve, a secondary vent passageway, an axially slidable piston, a suction duct, and a dispensing duct. The sleeve is rotatable by a user between an angular working position in which the main vent passageway is in fluid communication with the secondary vent passageway and an angular rest position, in which the main vent passageway is fluidically separated from the secondary vent passageway.

Provided is a trigger dispensing head applicable to a bottle of a trigger dispensing device having a cylinder chamber, a main vent passage, a sleeve, a secondary vent passage, a manually-operable piston, a suction duct, and a dispensing duct. The sleeve is provided with an annular inner sleeve wall delimiting a pressure chamber, and an annular outer sleeve wall externally spaced from the annular inner sleeve wall.

A trigger dispensing head for a dispensing device has a frame, a cylinder wall that delimits a cylinder chamber, a sleeve inserted into the cylinder chamber, a dispensing duct, a suction duct and valves for adjusting a flow of a product to be dispensed. The valves have a valve element having a support wall made of an elastically deformable material that is engaged between the sleeve and the cylinder wall to form a seal against leakage of the product.

A dispenser for pasty products having a fixed head that has a dispensing duct for dispensing a product, a pump with an elastically deformable cap, a manually-operated actuator, a separating wall with a suction inlet, and a suction valve cooperating with the suction inlet. The suction valve has a valve body and a plurality of tabs that bend and open the suction inlet in a product suction step, and close the suction inlet in a product dispensing step.

A trigger dispensing head applicable to a bottle suitable for containing a product to be dispensed is provided. The trigger dispensing head has valve elements having a dome-shaped valve body provided with an elastically deformable membrane. The elastically deformable membrane has an annular sealing ring that forms a head seal of a pre-stressing valve.

A dispenser for pasty products which has a head, a pump, an actuator, and a container tube is provided. The pump is provided with a flexible annular lip protruding out of the pump and inserted into an initial section of a dispensing tube of the head, configured to sealingly come into contact with an initial surface of the initial section to form an upper or delivery valve.
