Abstract: A device for dispensing a liquid from a container is disclosed, comprising: an engine, comprising a nozzle and a pump for transferring liquid from the container to the nozzle; a trigger, moveable between a first position and a second position, connected to the pump for actuating the pump when brought from the first to the second position, and connecting means, for connecting the engine to the container characterized by a slider with at least one restricting element, slideable between a non-restricting position, in which the trigger is moveable between the first and second position, and a restricting position, in which the at least one restricting element restricts the movement of the trigger between the first and the second position.

Abstract: The invention relates to a container for a product for dispensing, comprising a relatively stiff outer container (2) having at least one dispensing opening (3), and a deformable inner container (4) to be filled with the product which is accommodated in the outer container and which likewise has a dispensing opening (5). The inner container is connected to the outer container both in the vicinity of the dispensing opening and at least at one location remote therefrom. The connection is formed in that the outer container has an opening (8) through which protrudes at least one fixing element (10) connected to the inner container. This fixing element is pin-like and has an end part of which the dimensions are larger than those of the opening. The invention further relates to a method for manufacturing such a container.

Abstract: A liquid dispenser includes a container having an opening for receiving a liquid, and a dispenser subassembly having an outlet and a closing member cooperating with the outlet, the closing member being movable between a first closed position whereby the closing member engages the container opening and a second open position whereby the closing member is remote from the container opening. At least part of the dispensing subassembly is preformed on the container and the remaining part of the dispenser subassembly is connectable therewith.

Abstract: A precompression system for a liquid dispenser prevents liquid from being discharged from the dispenser until a predetermined pressure level has been attained within the dispenser. The liquid dispenser preferably has a liquid inlet and a liquid outlet for discharging the liquid. The precompression system includes a pump chamber having a piston movable in the pump chamber for drawing liquid through the inlet and discharging the liquid through the outlet. The precompression system also includes a valve chamber having a spring valve disposed between the pump chamber and the outlet and being operable to allow liquid in the pump chamber to reach the outlet only after a predetermined pressure is established in the pump chamber and to stop liquid from reaching the outlet when the pressure in the pump chamber falls below the predetermined pressure.

Abstract: A liquid dispenser includes a dispenser subassembly having an inlet, an outlet, and a pump in fluid communication with the inlet and the outlet, the pump being movable between a first position and a second position. The liquid dispenser also has a container including an opening for receiving a liquid and an actuating element connected thereto. The actuating element is engagable with the dispenser subassembly when the container and the dispenser subassembly are assembled together. Engagement of the actuating element with the dispenser subassembly is a prerequisite for operating the pump and dispensing the liquid from the dispenser. Also disclosed is a method of priming a liquid dispenser during final assembly thereof whereby the liquid dispenser will be immediately ready to discharge a liquid without further priming, such as is required with conventional liquid dispensers.
