DEVICE FOR ADMINISTERING A FLUID PRODUCT
Abstract
An administering device for a fluid product includes a product receptacle that accommodates the product to be administered, a fluid reservoir for a driving fluid, a driving means, a product chamber, and a fluid connection. The product receptacle includes an opening at a forward end and a product stopper at a rear end. The driving means acts upon the fluid reservoir, the pressure chamber adjoins the product stopper while the fluid connection is located between the fluid reservoir and the pressure chamber, and the driving means acts upon the fluid reservoir in such a way that the pressure chamber is impinged upon by pressure which affects the product stopper and the product is discharged from the product receptacle.
