Dispensing device

摘要

The device has a dispensing head, which is provided for dispensing liquid and/or a product such as foam and gel, from a container (3). The dispensing head is connected with a dispensing valve (18) of the container. A plastic material (15) is subjected to a preliminary treatment using plasma treatment or irradiation in a desired joining zone to form radicals or break open polymer chains of the plastic material. A polyolefin material (16) is sprayed directly against the plastic material, where the dispensing device is designed as a manually operated pump. An independent claim is also included for a method for manufacturing a dispensing device for a cosmetic liquid.
