Embodiment Construction

[0028] Now, figure 1 The actuating body 3 of the metering device 1 according to the invention is shown in an enlarged view. exist figure 1 , only the storage container 2 is schematically shown in the figure. Construction References About Storage Containers Figure 4 to Figure 7 .

[0029] Here, according to figure 1 The actuating body 3 of the shown embodiment comprises a cover 4 and a cylindrical hollow body 30 as well as a pump piston 5 connected as a single piece with the cover 4 and cylindrical hollow body 30 , which can be introduced in a form-fitting manner. into pump chamber 6. It is now essential that an outlet valve 36 is arranged in the end region of the outlet channel 8 , which includes a compression spring 33 and a valve piston 35 . The compression spring 33 is thus guided in the groove 34 , which is connected to the outlet channel 8 . The cover 4 is actuated by the user squeezing the cover 4 , the pump piston 5 is now moved into the pump chamber 6 , with th...

Abstract

The present invention relates to a metering device (1) for the metered discharge of liquid preparations, in particular for the metering of medicinal, pharmaceutical, and cosmetic liquid preparations, wherein the use of preservatives can be foregone.

Description

technical field [0001] The present invention generally relates to metering devices for the metered dispensing of liquid preparations, in particular for the metering of medical, pharmaceutical and cosmetic liquid preparations, wherein the use of preservatives can be dispensed with. The metering device can also be used in the field of food, for example in relation to food additives, flavorings and the like. Background technique [0002] A metering device for dispensing sterile fluids is known, for example, from EP 0 473 892 A2. However, the metering device described here is composed of a very large number of individual parts, which both makes the production unnecessarily complicated and expensive, and makes the metering device error-prone and fault-prone. [0003] Furthermore, with this known metering device it is not possible in all cases to meter the formulation to be metered with sufficient precision. Contents of the invention [0004] It is therefore an object of the p...
