Description

[0001] The present invention relates to a device for packaging and dispensing at least one fluid substance.

[0002] Devices are known for packaging and dispensing a fluid substance that comprise a container for containing said substance and an associated pump, the pump having a pump chamber into which the substance is taken before being delivered to the outside.

[0003] The pump has intake valve-forming means and delivery valve-forming means, respectively upstream and downstream from the pump chamber. The pressure required for expelling the substance from the device is obtained by means of a control rod that is movable in the pump chamber. A dispenser endpiece, such as a pushbutton fitted with a nozzle, is fixed to the control rod before the container is filled.

[0004] When a user presses on the dispenser endpiece, the control rod is pressed down into the pump body and reduces the volume of the pump chamber, causing a predetermined quantity of substance to be dispensed.

[0005] When the us...
