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.
Claims9
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.
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.

- 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.
