Abstract
Abstract The present invention relates to an apparatus for dispensing of a paste product. It comprises a container with an elastic outlet tube and a casing surrounding the container and provided with a push means for acting on the outlet tube for pressing out the product from the container. A contact piece is disposed in the push means which is removably mounted in the casing. The contact piece is made of elastic material and is provided with a projection disposed to close off the outlet tube against the container and with at least one tongue disposed to hold and return the push means to an inactive position where the outlet tube can be refilled. The apparatus can be disassembled and assembled without aids.

Total Claims: 5
Claim 1
Independent Claim
226 words
Apparatus for dispensing of a paste product, said apparatus comprising a. a container having an elastic outlet tube, said elastic outlet tube normally receiving paste from said container and adapted to be pressed to have paste expelled therefrom through an opening therein, b. a casing for receiving said container, said casing having an abuting member abuting said container outlet tube, c. means for pressing said elastic outlet tube against said casing abuting member for expelling paste therefrom without damage thereto, said means comprising a push means removably pivotally mounted in said casing and having a contact piece of elastic material disposed therein, said contact piece having a first integral projection of elastic material for engaging said outlet tube and closing off said outlet tube against said abuting member, whereby said projection engages and closes off said outlet tube and then said contact piece of said push means presses said outlet tube to expel paste therefrom, and d. means for biasing said push means to a position wherein said outlet tube is not pressed but is free to receive paste from said container, said means comprising a pair of second projections of elastic material extending from and integral with said contact piece and straddling said first projection and said outlet tubing, each of said projections having a free end thereof engaging said abuting member of said casing.
Claim 2
Dependent Claim
