A pump apparatus (1) comprises a pump head (2) and a container (20) for a liquid to be dispensed. The pump head (2) has a flexible dispensing tube (4) in fluid connection with the inside of the container (20). The fluid connection between the dispensing tube (4) and the inside of the container (20) is provided by a supply tube (28) which co-operates with the dispensing tube (4) to provide a non-return valve function. An end (48) of the supply tube (28) is disposed within an end of the dispensing tube (4) and the non-return valve function is provided by a hole (46) through a side wall of the supply tube (28) in a region where the dispensing tube (4) overlaps the supply tube, whereby the dispensing tube (4) provides a seal over the hole (46) to prevent ingress of fluid when the internal pressure is lower than the external pressure. Another aspect of the invention provides a container (20) for use in the pump apparatus.

A device for dispensing a product includes: a module including a head and a reservoir, the head including a conduit connecting the inside of the reservoir to an outlet of the head; and a housing having at least two mutually movable parts including an upper part and a lower part, the at least two parts being arranged to be assembled so as to receive the module inside the housing.

The bottle and spray assembly is a device that is designed pump liquids through a nozzle. The pump of the bottle and spray assembly is manually operated. The bottle and spray assembly is designed to rest on the arm of the user while the user holds a handle. The placement of bottle and spray assembly is in such a manner that the arm holds the bottle and spray assembly in place while the user pulls on the handle. The motion of pulling the handle operates the pump action within the spray assembly, which pumps the liquid through a nozzle. The bottle and spray assembly comprises a bottle and a spray assembly.

A plunger pump, comprising: a liquid tank; a pump body including a liquid storage part, a suction passage configured to allow communication between the liquid storage part and the liquid tank and a discharge passage configured to discharge a liquid in the liquid storage part to outside; and a plunger reciprocally movably supported in the pump body so that a tip reaches the liquid storage part. The suction passage includes a first suction passage, the tip of the plunger being reciprocally slidably inserted into the first suction passage, and a second suction passage provided in parallel to the first suction passage, and a check valve configured to allow only a flow of the liquid from the liquid tank to the liquid storage space is disposed in the second suction passage.

A dispenser for discharging pharmaceutical liquids in the form of individual drops, having a liquid store, a pump device with a pump chamber with a variable volume, and a dispensing opening. The dispenser additionally has a membrane part which delimits the pump chamber on one side and which changes the volume of the pump chamber by moving and/or deforming. The dispenser has a housing, within which the pump device is provided, and an actuation button movable relative to the housing between a non-actuated starting position and an actuated end position to move or deform the membrane part and to decrease the size of the pump chamber to discharge the liquid. The membrane part.is secured to the housing and to the actuation button. The pump chamber achieves a high degree of compression and a toggle switch is used as the actuation button.

A dispenser for discharging pharmaceutical liquids, in particular in the form of individual drops. Such a dispenser is designed as a side-actuation dispenser with an actuation button on the dispenser in the region of a lateral surface of the housing and has a liquid store, a pump device with a pump chamber which has a variable volume, and a dispensing opening for dispensing the liquid. The actuation button is a spring-loaded toggle switch, the volume of the liquid channel is reduced using an insert, and a special housing design is provided for the purpose of adapting the dispenser to the customer's needs.

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 plurality of flexible flaps protruding inwardly from a dome-shaped elastically deformable cap of the pump or from a connection portion of the pump to form a lower or suction valve.

A system for refilling a trigger sprayer bottle assembly includes the trigger sprayer bottle assembly including a trigger movable between a first trigger position and a second trigger position. A refillable bottle is coupled to the trigger such that material within the refillable bottle is dispensed from the refillable bottle when the trigger is moved from the first trigger position to the second trigger position. The trigger sprayer bottle assembly includes a first refill port through which material is added to the refillable bottle. The trigger sprayer bottle assembly is selectively coupled to a refilling assembly. The refilling assembly includes a refill reservoir and a second refill port through which material is removed from the refill reservoir. The second refill port is selectively coupled to the first refill port when the trigger sprayer bottle assembly is coupled to the refilling assembly.

A dispenser includes a housing having a depression; an elastically deformable lid section covering an opening of the depression and forming a pump chamber together with the depression; a pressing portion arranged facing the lid section on the outside of the pump chamber, capable of pressing the lid section to a side where the volume of the pump chamber decreases, and provided to be able to enter the inside of the depression while pressing the lid section for elastic deformation; an outlet causing a liquid material inside the pump chamber to flow out toward a discharging opening when the pressing portion presses the lid section; and an inlet provided separately from the outlet and causing the liquid material to flow into the pump chamber when the pressing to the lid section by the pressing portion is released.

A dispensing device for paste products, including toothpaste, is provided. The dispensing device includes a container, a pumping diaphragm and a head applied to the container. The head is equipped with a tube and a button for acting on the diaphragm and deforming it for dispensing. The button has a pressure surface for a user's dispensing action. An extension element which, in an active position, is arranged as an extension of the pressure surface of the button, increases a leverage effect.
