Claims

[Claims for Utility Model Registration] 1. A product dispensing device configured to accommodate a product in an axial hole of a tubular container body having an upper end for dispensing the product and an open lower end, The container includes a driven piston slidably attached to the lower end of the hole in the container body to support the product, the piston being made of an elastic material, and having a front portion that contacts the product and a static a friction ring dimensioned to be a tight fit within the bore so as to apply a predetermined vertical pushing force against the inner surface of the bore in the condition, and an outer circumferential side wall; At least two pendulums fixed to the upper outer periphery of the friction ring at the depending lower end.
one opposed helical strip, said helical strip conforming to the cross-sectional shape of said hole at least two opposite helical strips;
two circumferential contact bands, said sidewalls substantially elastically expanding and contracting in a longitudinal direction to produce a variation in length in response to an axial pushing force applied to said front portion;
An applicator, which results in an inversely proportional variation in the lateral dimension of the circumferential contact band, and wherein the driven piston is hollow and the inner surface of its front and side walls are exposed to the atmosphere. 2. Said driven piston further comprises two right-hand helical strips depending from the lower edge of said front part and fixed at their lower ends to the upper edge of said friction ring.
2. The applicator of claim 1, wherein said helical strip includes two left-handed helical strips, each said helical strip being formed as a complete helical revolution and having a perforated side wall. 3. Said driven piston further includes a depending end friction ring, said ring dimensioned to be a tight fit within said bore, and in static conditions to a predetermined perpendicular to the inner surface of said bore. The side wall further includes at least two opposing helical strips depending from the lower edge of the front portion and secured at their lower ends to the upper edge of the friction ring, the helical strips having a cross-sectional shape of the aperture. The applicator according to claim 1, characterized in that it forms at least two outer circumferential contact bands in accordance with the above.
