A soap dispenser can be configured to dispense an amount of liquid soap, for example, upon detecting the presence of an object. Certain embodiments of the dispenser include a housing, reservoir, pump, motor, sensor, electronic processor, and nozzle. In certain embodiments, the sensor can be configured to generate a signal based on a distance between an object and the sensor. In certain embodiments, the electronic processor can be configured to receive the signal from the sensor and to determine a dispensation volume of the liquid. The dispensation volume can vary as a function of the distance between the object and the sensor. The processor can be configured to control the motor to dispense approximately the dispensation volume of the liquid.

In a pump assembly, the outer wall of the first inner-housing sidewall, the inner wall of the second inner-housing sidewall and the inner-housing top wall define a first chamber with a first opening, and the gas chamber of the first chamber is a sealed chamber collectively defined by the piston portion, the inner-housing top wall, the outer wall of the first inner-housing sidewall and the inner wall of the second inner-housing sidewall, so that the formation of the sealed chamber does not require an additional sealing ring. This thereby reduces the risk of gas leakage due to aging of the sealing ring. A container with contents discharge function provided by this disclosure can include the above pump assembly.

The invention relates to a packaging device comprising a bottle containing a product to be distributed and having a neck, and a dispensing device comprising a body arranged in the neck. A cache masking the body of the dispensing device is arranged in the neck of the bottle.

The present invention concerns a vial with a neck for a liquid product with an external shape, comprising: a part made from glass, said part made from glass comprising an annular assembly surface; a rigid piece having an annular assembly surface; a neck formed on the part made from glass or the rigid piece; a neck providing a fluid seal either between the annular assembly surface of the part made from glass and the annular assembly surface of the rigid piece, or between the annular assembly surface of the part made from glass and a sealing band, the sealing band being rigidly connected to the annular assembly surface of the rigid piece, thus providing the fluid seal, the part made from glass, the rigid piece and the neck giving the vial the external shape of same.

Dispenser device for liquids, comprising: —a dispenser head (1); —a replaceable, flexible receptacle (2), containing the liquid to be dispensed and which has a valve (21) provided with a seal (22) for opening and closing; —a rigid container (3) for securing the flexible receptacle, provided with a mouth (32) for the mechanical coupling of the dispenser head (1) and of means (33) for the coupling and securing of the valve (21) of the flexible receptacle (2) in a position facing the mouth (32) of the rigid container (3); and —a hydraulic coupling part (4) of the dispenser head to the flexible receptacle, which is automatically coupled to and decoupled from the seal (22) of the valve (21) and displaces it towards an open position and towards a closed position when the dispenser head (1) is coupled to and decoupled from the rigid container (3), respectively.

Provided is a fluid container including: a container main body, of which one side is open, configured to store a fluid; a housing having an outlet provided at one side and in which the container main body slides in a longitudinal direction; and a pump module coupled to the open one side of the container main body and configured to discharge the fluid to the outlet by sliding the container main body.

A lotion pump includes an internally threaded sleeve; a spring-loaded dip tube including an annular first flange on an outer surface, and an internal shoulder; a first housing including a tapered head, a chamber spaced from the tapered head, a tunnel communicating between the tapered head and the chamber, overflow openings on the tunnel, and first external threads on an outer surface of the chamber; a check valve; a second housing including an open first chamber member, an open second chamber member, a channel communicating between the first chamber member and the second chamber member, second external threads, and an annular second flange on an outer surface; a support including an annular third flange on an outer surface, and an second opening; a spring-loaded valve; and an internally threaded cup including an annular fourth flange on an outer surface, and a second hole through a second end.
