Dispenser for a viscous fluid product operated by manual pressure on a bottom end thereof, in particular for cosmetic or pharmaceutical use
First Claim
1. A dispenser of viscous fluid product having a dispensing action produced by a manual pressure on a bottom surface thereof, for cosmetic and pharmaceutical use, comprising,a tubular outer body having an open top end and a partially closed bottom end with a centrally located wide aperture, said outer body externally exhibits a first annular shoulder dividing the outer body into a top portion and a bottom portion, the top portion being thinner in breadth than the bottom portion;
- a tubular hollow recipient removably housed in the outer body, exhibiting an external wall and a tubular internal surface and being superiorly closed by a top wall affording a dispensing aperture for dispensing the product, and being open at a bottom end;
a tubular piston, housed internally in the bottom end of the tubular recipient and provided with a lateral seal;
said piston being mobile in a direction along the tubular internal surface when the manual pressure is applied thereupon in proximity of the aperture in the outer body at a central portion of the piston and coaxial to an axis of the aperture;
a lid;
first means for reciprocal and releasable engagement between the tubular recipient and the tubular outer body; and
second means for reciprocal gripping between the tubular outer body and the lid.

Abstract
A dispenser of products such as creams and the like for cosmetic or pharmaceutical use having a lid which closes on to a first annular abutment of a tubular outer body. The outer body having an open bottom end with an aperture wherethrough a recipient containing the product is inserted and removed and a top end which is open. The recipient having an open bottom end housing a piston which when manually pressed in an axial direction, without rotation, presses the product in the recipient towards a dispensing aperture provided in a closed end of the recipient such as to dispense a continuous quantity and not a prefixed dose of product.

8. A dispenser of viscous fluid product having a dispensing action produced by a manual pressure on a bottom surface thereof, for cosmetic and pharmaceutical use, comprising,
a tubular outer body having an open top end and a partially closed bottom end with a centrally located wide aperture, said outer body externally exhibits a first annular shoulder dividing the outer body into a top portion and a bottom portion, the top portion being thinner in breadth than the bottom portion; -
a tubular hollow recipient removably housed in the outer body, exhibiting a first external wall and a second external wall and being superiorly closed by a top wall affording a dispensing aperture for dispensing the product, and being open at a bottom end; a tubular piston, housed internally in the bottom end of the tubular recipient and provided with a lateral seal;
said piston being mobile in a direction along the first external wall when the manual pressure is applied thereupon in proximity of the aperture in the outer body at a central portion of the piston and coaxial to the aperture;a lid; wherein the recipient housed in the outer body has a second abutment which divides the second external wall into two portions which are unitary with the first external wall;
said two portions being a lower wall and an upper wall;
said lower wall being internally provided with a first thread coupling with a first counter thread made on the outer body, said lower wall projecting externalwise of said outer body and being annularly concentric to and shorter than the first external wall;
said upper wall exhibiting a second thread coupling with a second counter thread exhibited by the lid.

9. A dispenser of viscous fluid product having a dispensing action produced by a manual pressure on a bottom surface thereof, for cosmetic and pharmaceutical use, comprising,
a tubular outer body having an open top end and a partially closed bottom end with a centrally located wide aperture, said outer body externally exhibits a first annular shoulder dividing the outer body into a top portion and a bottom portion, the top portion being thinner in breadth than the bottom portion; -
a tubular hollow recipient removably housed in the outer body, exhibiting an external wall and a tubular internal surface and being superiorly closed by a top wall affording a dispensing aperture for dispensing the product, and being open at a bottom end; a tubular piston, housed internally in the bottom end of the tubular recipient and provided with a lateral seal;
said piston being mobile in a direction along the internal tubular surface when the manual pressure is applied thereupon in proximity of the aperture in the outer body at a central portion of the piston and coaxial to the aperture;a lid; wherein a separator body is separately and removably engaged on the external wall of the recipient;
the separator body having a second annular shoulder which divides the separator body into two portions;
said two portions being a lower wall and an upper wall;
said lower wall being internally provided with a first thread coupling with a first counter thread on said outer body;
said upper wall exhibiting a second thread coupling with a second counter thread exhibited by the lid.
