Benefits of technology
"The present invention provides a metering pump arrangement and method for producing a filled metering pump arrangement, where the residual air in the container is easily removed through the pump. The pump arrangement includes a lid with a recess, which faces the container, and the intake opening of the pump does not project beyond the lid. The intake opening can be sealed with the lid, and the residual air can be drawn off through the pump. The pump arrangement can be used with various types of kick-back valves, such as balls or rubber lips, and can be used with low-viscosity or highly viscous substances. The container can have a changeable volume, and a rigid sheath can be used to hold the arrangement. The invention simplifies the process of dispensing residual air from containers and makes it easier to handle the pump arrangement."
Problems solved by technology
In order to avoid having the pump project all the way into the fluid with its intake opening, which is desirable for dispensing the fluid in pump operation, but is unsuitable for drawing the residual air out of the container, the intake opening must end as flush as possible with the inner wall of the container, or project at most only a few millimeters into the interior of the container.

Embodiment Construction
[0044] The metering pump assembly or arrangement 1 according to FIG. 1 has a collapsible film bag 2 as a container, which is filled with a fluid, for example a fluid pharmaceutical or cosmetic product. As will be explained in greater detail below, film bag 2 is connected with a pump 3, in sealed manner, which pump, in the exemplary embodiment shown, includes a pressure chamber 4 having a piston 5 that glides in it, and two kick-back valves 6 and 7, respectively.
[0045] In pressure chamber 4, a spring 8 is provided in such a manner that piston 5 is impacted upward in FIG. 1. Piston 5 has a central passage opening 9, through which a fluid can be pumped out of film bag 2 into the surroundings.
[0046] For this purpose, the first kick-back valve 6 is set in such a manner that this kick-back valve 6 permits flow out of film bag 2 into pressure chamber 4 if the ball-shaped valve element or body 6a is lifted off its valve seat 6c by means of a partial vacuum in pressure chamber 4, counter t...

A method for the production of a filled metering pump arrangement fills a product capable of flow into a film bag, which may be received in a container, for example. The film bag is closed by means of a pump that can be activated manually, which blocks a fluid connection between an outlet opening and the interior of the film bag, in the unstressed state, by means of at least one kick-back valve. The gas situated in the film bag is removed, at least substantially completely, by compressing the film bag, particularly by means of a punch or similar device.
Description
CROSS REFERENCE TO RELATED APPLICATIONS [0001] Applicant claims priority under 35 U.S.C. §119 of German Application No. 10 2005 022 044.4 filed Apr. 21, 2005 and German Application No. 10 2005 043 839.3 filed Sep. 15, 2005. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a metering pump arrangement having a container that is connected, in sealed manner, with a pump that can be manually activated. The pump blocks off a fluid connection between an outlet opening of the pump that stands in connection with the surroundings, and the interior of the container, by means of at least one kick-back valve, in the unstressed state. Furthermore, the present invention relates to a method for the production of a filled metering pump arrangement, as well as to the use of such a metering pump arrangement. [0004] 2. The Prior Art [0005] A dispensing device for fluids is known from DE 100 49 898 C2, with which liquid pharmaceuticals or cosmetics, fo...
