Abstract

A device for dispensing a fluid substance (F) comprising a manually operated pump ( 2 ) coupled to a deformable bag ( 3 ), the deformable bag being housed inside a container ( 4 ); the container is formed of a collar ( 5 ) made of plastic coupled to a tubular element ( 6 ) formed from a paper- or cardboard-based material, the tubular element featuring a bottom ( 7 ), the collar ( 5 ) featuring ribs (N) made on a surface thereof which comes into contact with an internal wall of the tubular element ( 6 ).

First claim

The invention claimed is:

1. A dispensing device of a fluid substance (F), comprising a manually operated pump ( 2 ) coupled to a deformable bag ( 3 ), the deformable bag being housed inside a container ( 4 ), characterized in that the container is formed by a collar ( 5 ) made of plastic material coupled to a tubular element ( 6 ) formed in a material comprising paper or cardboard, the tubular element providing a bottom ( 7 ), the collar ( 5 ) providing a plurality of ribs (N) made on a contact surface of the collar ( 5 ) with an internal wall of the tubular element ( 6 ), the plurality of ribs (N) being parallel with respect to an axis (A) of the tubular element, said plurality of ribs being impressed into the material of the tubular element to facilitate fastening between the collar ( 5 ) and the tubular element ( 6 ).

2. The dispensing device according to claim 1 , wherein at least two slots ( 19 ) are formed on the collar ( 5 ) to improve its deformability, thereby facilitating the insertion of the collar ( 5 ) into the tubular element ( 6 ).

3. The dispensing device according to claim 1 , in which the tubular element ( 6 ) has an area ( 6 A) which is inserted in an annular groove ( 8 ) obtained in the collar ( 5 ).

4. The dispensing device according to claim 1 , in which the annular groove ( 8 ) has an inclined plane ( 8 A) which undercuts one end of the area ( 6 A) when the tubular element ( 6 ) is coupled to the collar ( 5 ).

5. The dispensing device according to claim 1 , wherein an annular wall ( 7 A) extends from the bottom ( 7 ) towards an inside of the tubular element ( 6 ) wherein a free end of the deformable bag ( 3 ) is inserted into the annular wall so as to limit the movement of the bag inside the tubular element ( 6 ) when the bag is full.

6. The dispensing device according to claim 1 , wherein the bottom ( 7 ) is made of material comprising paper or cardboard.

7. The dispensing device according to claim 1 , wherein the collar ( 5 ) provides at least one undercut ( 9 ) to which a locking element ( 10 ) of the pump is snapped onto the collar ( 5 ).

8. The dispensing device according to claim 7 , in which the pump ( 2 ) has a first flange ( 2 A) and the deformable bag has a second flange ( 3 A) which are mutually placed and sandwiched between the collar ( 5 ) and the locking element ( 10 ).

9. The dispensing device according to claim 1 , wherein the collar ( 5 ) has a thread ( 12 ) on which an intermediate element ( 13 ) is screwed, a flange ( 3 A) of the deformable bag ( 3 ) resting on the intermediate element ( 13 ), the intermediate element ( 13 ) having an undercut ( 9 ) for the snap coupling of the locking element ( 10 ) of the pump ( 2 ).

10. The dispensing device according to claim 1 , in which the collar ( 5 ) provides an air passage (P) in communication with the interior of the tubular element ( 2 ), and/or in which one end of the collar ( 5 ) has a toothed crown (C) which allows the passage of air inside the tubular element ( 2 ).
