Abstract

This cosmetic product dispensing head ( 30 ) comprises:
a dispensing member ( 32 ) for the cosmetic product, having a tubular duct ( 34 ) defining a passage ( 36 ) for the cosmetic product, and a stopper ( 60 ) for closing off the passage ( 36 ), movable between a position freeing the passage ( 36 ) and a position closing off the passage ( 36 ), the stopper ( 60 ) comprising a finger ( 62 ) and a skirt ( 64 ), the outer face ( 48 ) of the duct ( 34 ) and the inner face ( 78 ) of the skirt ( 64 ) having complementary cooperating means ( 80, 82 ) for securing the stopper ( 60 ) to the dispensing member ( 32 ).

The finger ( 62 ) bears a peripheral scraping member ( 70 ) protruding radially from a peripheral face ( 72 ) of the finger ( 62 ), the scraping member ( 70 ) having at least one perimeter line ( 74 ) suitable for being in contact with the duct ( 34 ) when the stopper ( 60 ) is in the closing off position.

First claim

The invention claimed is:

1. A cosmetic product dispensing head, comprising:
a dispensing member for the cosmetic product, having a tubular duct defining a passage for the cosmetic product, the duct having an outer face oriented opposite the passage, and
a stopper for closing off the passage, movable between a position freeing the passage and a position closing off the passage, the stopper comprising a finger extending in the passage when the stopper is in the closing off position and a skirt extending around the duct when the stopper is in the closing off position, the skirt having an inner face oriented toward the finger,
the outer face of the duct and the inner face of the skirt having complementary cooperating elements for securing the stopper to the dispensing member,
in which the finger bears a peripheral scraping member protruding radially from a peripheral face of the finger, the scraping member having at least one perimeter line suitable for being in contact with the duct when the stopper is in the closing off position,
wherein the dispensing member has an annular protrusion protruding radially from the duct toward the inside of the passage, the protrusion defining a shoulder, and the scraping member is suitable for being in contact with said shoulder along a closed contour line when the stopper is in the closing off position, and
wherein the duct has an insertion end for inserting the finger into the passage and a connecting end for connecting the passage to a cosmetic product reservoir, opposite the insertion end, the annular protrusion protruding from said connecting end, the scraping member having a perimeter line suitable for being fully in contact with the duct for any position of the stopper in which the scrapping member is engaged in the passage.

2. The dispensing head according to claim 1 , wherein the finger has a junction end to the skirt and a free end, and the perimeter line is closer to the free end than the junction end.

3. The dispensing head according to claim 1 , comprising an airtight and fluid-tight membrane seal tightly sealed to the dispensing member, the membrane seal being separate from the stopper, the membrane seal extending through or across from the passage.

4. The dispensing head according to claim 3 , wherein the finger has a junction end to the skirt and a free end, the free end being suitable for perforating the membrane seal when the stopper is in the closing off position.

5. The dispensing head according to claim 4 , wherein the free end is beveled so as to facilitate the perforation of the membrane seal.

6. The dispensing head according to claim 4 , comprising a removable safety member suitable for keeping the stopper in an intermediate position between its released and closing off positions, in which the free end of the finger is at a distance from the membrane seal.

7. The dispensing head according to claim 1 , wherein the complementary cooperating elements comprise a thread on the outer face of the duct and a tapping—on the inner face of the skirt.

8. The dispensing head according to claim 1 , wherein the duct has an inner face defining the passage, said inner face being substantially smooth.

9. The dispensing head according to claim 1 , wherein the duct is substantially rectilinear.

10. The dispensing head according to claim 1 , wherein the scraping member is made in one piece together with the finger.

11. A cosmetic product packaging device, comprising a reservoir containing a cosmetic product and a dispensing head closing said reservoir, wherein the dispensing head is a dispensing head according to claim 1 .

12. A method for dispensing a cosmetic product using a dispensing head according to claim 1 , which comprises the following successive steps:
moving the stopper into the released position,
circulating the cosmetic product in the passage, and
returning the stopper to the closed off position, the scraping member rubbing along its perimeter line against the duct and driving the cosmetic product present in the passage with it.

13. The dispensing head according to claim 2 , comprising an airtight and fluid-tight membrane seal tightly sealed to the dispensing member, the membrane seal being separate from the stopper, the membrane seal extending through or across from the passage.

14. The dispensing head according to claim 5 , comprising a removable safety member suitable for keeping the stopper in an intermediate position between its released and closing off positions, in which the free end of the finger is at a distance from the membrane seal.
