Abstract
The invention relates to a device for packaging and dispensing at least one fluid substance. The device has at least one container filled with a substance by a vacuum-filling process, a pump associated with the container and having a pump chamber into which the substance is drawn prior to being delivered to the outside, and anti-vacuum valve-forming means organized to isolate the pump chamber(s) of the pump(s) from the inside(s) of the associated container(s) when a vacuum is established therein for filling purposes.
Claims14
A device for packaging and dispensing at least one fluid substance, the device comprising at least one container filled with a substance by a vacuum-filling process, a pump associated with the container having a pump chamber into which the substance is drawn prior to being delivered to the outside, and anti-vacuum valve-forming means organized to isolate the pump chamber(s) of the pump(s) from the inside(s) of the associated container(s) when a vacuum is established therein for filling purposes.
A method of manufacturing a device for packaging and dispensing at least one fluid substance, said device having at least one container for containing a substance and a pump for dispensing it, the pump having a pump chamber into which, in operation of the pump, the substance is drawn prior to being delivered to the outside, the method comprising the steps consisting in:
- assembling together the pump, the container, and anti-vacuum valve-forming means, the container being suitable for communicating via a first opening with the pump chamber via the anti-vacuum valve-forming means;
- evacuating the inside of the container via a second opening thereof, the anti-vacuum valve-forming means isolating the container from the pump chamber during the evacuation step;
- filling the container by causing it to communicate via said second opening with a source of substance;
- and
- closing said second opening.
A method of manufacturing a packaging and dispenser device having two containers for separately containing respective substances, and two pumps respectively associated with said containers for dispensing said substances simultaneously, each of the pumps having a pump chamber into which, during operation of the pump, the substance is drawn prior to being delivered to the outside, the method comprising the steps consisting in:
- assembling each pump fitted with anti-vacuum valve-forming means to the associated container;
- filling each container separately by a vacuum-filling process;
- inserting both pumps and the associated containers in a case;
- and
- fitting the case with a dispenser endpiece common to both pumps.
