Dispenser unit for liquid products

1. A dispenser unit comprising:

a bottle adapted to contain a liquid product, said bottle having a recessed seat that is open on a bottom thereof and extends in a longitudinal direction, said bottle having at least one blind hole formed in the recessed seat and extends radially toward an interior of said bottle;

a dispenser applied to said bottle and adapted to dispense the liquid product; and

a fixing system adapted to fix said bottle to a wall, said fixing system comprising:

a first plate adapted to be fixed to the wall;

a second plate fixed to said bottle in the recessed seat, said second plate being coupled to said first plate, said second plate having at least one fixing pin engageable with the blind hole of said bottle; and

a key adapted to uncouple said first plate from said second plate.

2. The dispenser unit of claim 1 , further comprising:

a blocking device applied to said second plate so as to fix said second plate to said bottle.

3. The dispenser unit of claim 2 , wherein the at least one fixing pin of said second plate has a cylindrical or a truncated-conical shape with a through hole and a plurality of notches that define a plurality of flexible tabs with a retention tooth that projects outwardly.

4. The dispenser unit of claim 3 , wherein said blocking device has a plate and at least one pin that protrudes frontally from the plate of said blocking device, the at least one pin being engaged in the through hole of the at least one fixing pin of said second plate so as to diverge the plurality of flexible tabs of the at least one fixing pin.

5. The dispenser unit of claim 1 , wherein said first plate has guide tracks that protrude frontally and longitudinally from a lateral edge of said first plate, said second plate having guide tracks that protrude in a back of and longitudinally from said second plate adjacent to lateral edge of said second plate, wherein the guide tracks of said second plate are slidingly engaged with guide tracks of said first plate, the guide tracks of said second plate being complementary to the guide tracks of said first plate such that said second plate is longitudinally slidable on said first plate so as to prevent a removal of said second plate in an orthogonal or oblique direction relative to the wall.

6. The dispenser unit of claim 5 , wherein the guide tracks of said first plate and the guide tracks of said second plate have an L-shaped cross-section.

7. The dispenser unit of claim 2 , wherein said first plate has a transverse rib that protrudes at a back of said first plate, the second plate having at least one longitudinal slot and at least one longitudinal flexible tab disposed inside the at least one longitudinal slot in an inclined orientation relative to said second plate, the at least one longitudinal flexible tab having a stop end that protrudes at a back of said second plate so as to be stopped against the transverse rib of said first plate so as to prevent an upward and downward translation of said second plate relative to said first plate, said key having at least one prong that pushes the at least one longitudinal flexible tab of said second plate inside the at least one longitudinal slot of said second plate such that the stop end of the at least one longitudinal flexible tab is not stopped against the transverse rib of said first plate so that said second plate can translate upwardly and downwardly on said first plate.

8. The dispenser unit of claim 7 , wherein said first plate has at least two longitudinal ribs that define at least one groove in which the prong is guided.

9. The dispenser unit of claim 8 , wherein said blocking device has a plate with a lower edge that is stoppable against the transverse rib of said first plate so as to prevent an upward and downward translation of said second plate on said first plate.
