Embodiment Construction

[0035] according to figure 1 The dosing pump device 1 has a collapsible film bag 2 as container, which is filled, for example, with a liquid medicinal or cosmetic product. The film bag 2 (as explained in more detail below) is connected in a sealing manner to a pump 3 which, in the embodiment shown, comprises a pressure chamber 4 with a piston 5 sliding therein and two non-return valves 6 or 7 .

[0036] A spring 8 is arranged in the pressure chamber 4 in such a way that the piston 5 is biased upwards in the figure. The piston 5 has a central through-opening 9 through which the fluid is pumped from the film bag 2 to the environment.

[0037] For this purpose, the first non-return valve 6 is designed in such a way that if the spherical valve element 6a is lifted from its valve seat 6c against the force of the valve spring 6b due to the low pressure in the pressure chamber 4, it allows Flow of bag 2 into pressure chamber 4. However, the flow in the opposite direction from the ...

Abstract

The invention relates to a method for producing a filled dosing pump device, wherein a flowable product is filled into a film bag (2), which is contained, for example, in a container (11). The film bag (2) is closed via a manually operable pump (3), which is closed in the unloaded state via at least one non-return valve (6, 7) at the outlet (14) connected to the environment and Fluid communication between the interiors of the film bag (2). In addition, the gas located in the film bag ( 2 ), which is compressed by means of punches ( 16 ) or the like, is at least nearly completely vented.

Description

technical field [0001] The invention relates to a dosing pump device having a container which is tightly connected to a manually operable pump which, in the unloaded state, closes the pump from the environment via at least one non-return valve Fluid communication between the discharge port and the interior of the container. Furthermore, the invention relates to a method for producing a filled dosing pump device and the use of such a dosing pump device. Background technique [0002] A dispensing device for fluids is known from DE 100 49 898 C2, by means of which eg liquid pharmaceuticals or cosmetics can be dispensed quantitatively from a container. The dosing pumps used for this work without air compensation, wherein the liquid in the container is contained in an inner bag which is sealed from the outside and which collapses during emptying. [0003] Filling such inner bags with liquids such as pharmaceuticals or cosmetics is usually done in such a way that residual air re...
