Abstract
A metering pump arrangement has a container with a changeable volume for accommodating a fluid. The arrangement has a pump that can be connected with the container in a sealed manner, which can be manually activated. The pump has an outlet opening that is connected with the surroundings. A bypass channel runs outside the pump and connects the container with the surroundings. The bypass channel can be sealed off by way of a closure element. The arrangement may be used for metering, dispensing or applying cosmetics or pharmaceuticals. A method is also provided for producing a metering pump arrangement.
Claims20
A metering pump assembly comprising
- (a) a container with a changeable volume for accommodating a fluid;
- (b) a manually-activatable pump sealably connected with the container having an outlet opening connected with an outside area;
- (c) a bypass channel outside the pump connecting the container with the outside area;
- and
- (d) a closure element for sealing the bypass channel from the outside area.
A device for metering, dispensing, or applying cosmetics or pharmaceuticals comprising a metering pump assembly comprising a container with a changeable volume for accommodating a fluid, a manually-activatable pump sealably connectable with the container having an outlet opening connected with an outside area, a bypass channel outside the pump connecting the container with the outside area, and a closure element for sealing the bypass channel from the outside area.
A method of providing a metering pump system comprising the following steps:
- (a) providing a container having a lid, a pump connectable with the container, and a bypass channel outside the pump;
- (b) filling the container with a fluid product;
- (c) closing the container after filling, except for the bypass channel, by means of the pump or the lid;
- (d) drawing off residual gas remaining in the container substantially completely through the bypass channel;
- and
- (e) closing off the bypass channel at least in one flow direction from an outside area into the container.
