Abstract

An applicator dispenser has a container defining a tank with a lateral wall and a neck integral with a wiper. An applicator includes a cap having an outer shell and a threaded insert, and an axial wand fixedly attached to the insert and to an application means. The lateral wall of the tank forms at its upper part a straight skirt. The container has a closure component having an upper part forming the neck, a peripheral part engaging in a sealed way with the straight skirt, and a lower part engaging with the wiper forming a forward axial stop for the wiper. The wiper has a central part forming a swaged wiping part and a lateral part engaging with the lower part of the closure component.

Claims

wherein said wiper forms a molded component distinct from said closure component, said wiper comprising a central part forming said swaged part and a lateral part engaging with said lower part of said closure component by a secondary assembly, so as to form an assembly component.

2. A dispenser according to claim 1 wherein all or part of said lateral part of said wiper, which engages with said lower part of said closure component, is placed axially underneath said lower part, in such a way that said lower part forms said axial stop for said lateral part of said wiper, so that any axial stress exerted by said application means on said wiper when said applicator is separated from said container is transferred to said closure component, wherein said closure component is fixedly attached to said tank to prevent forward axial displacement of said wiper.

3. A dispenser according to claim 1 wherein the whole of said lateral part of said wiper is placed underneath said lower part of said closure component, in such a way that said lateral part is included within an axial projection of said lower part in a transverse plane perpendicular to said axial direction.

4. A dispenser according to claim 1 wherein said lateral part of said wiper and said lower part of said closure component engage through the use of axial snap-on means.

5. A dispenser according to claim 4 wherein said lateral part of said wiper comprises at least one axial projection selected from the group consisting of an inner axial projection, a central axial projection, and an outer axial projection, wherein said inner and outer projections form between them an annular groove engaging with an annular groove of said lower part, said central axial projection engaging with an annular groove of said lower part.

6. A dispenser according to claim 3 wherein said lateral part of said wiper comprises a transverse cross section, in a transverse plane perpendicular to said axial direction, axially facing said lower part of said closure component, so that said assembly component has substantially cylindrical inner and outer axial surfaces and in such a way that said transverse cross section and said axial projection are substantially facing each other along said axial direction.

7. A dispenser according to claim 1 wherein said central part of said wiper forms or comprises a radial ring having an outer diameter and an inner diameter, said radial ring having a thickness that may or may not be constant between the outer diameter and the inner diameter, wherein the thickness is selected to ensure the flexibility of said radial ring and the inner diameter is equal to or greater than the diameter of said axial wand.

8. An applicator dispenser for a cosmetic product, the applicator dispenser having an axial direction and comprising:

a) a container comprising a neck threaded on the outside and a longitudinal tank fitted with a lateral wall and forming a cavity for packaging said cosmetic product, said neck being integral with a wiper of said application means comprising a swaged wiping part delimiting a central orifice;

b) an applicator of said cosmetic product comprising a cap forming a means of gripping said applicator, said cap comprising an outer shell and an insert threaded internally so as to engage with said neck by screwing so as to provide a sealed closure of said container, an axial wand fixedly attached by its upper end to said insert and by its lower end to an application means, said application means being physically immersed in said product when said cap of said applicator is screwed onto said neck;

wherein said lateral wall of said tank forms or comprises at its upper part a straight skirt, open at its upper end;

wherein said container comprises a component for closing said upper opening integral with said tank, said closure component forming a molded component distinct from said tank and comprising an upper part forming said neck, a peripheral part engaging in a sealed way with said straight skirt of said tank via an axial assembly, and a lower part engaging with said wiper forming a forward axial stop for said wiper;

wherein said straight skirt comprises a thinned out part with an inner channel forming an inner shoulder, so as to form an inner rebate, said inner shoulder forming an axial stop for said peripheral part of said closure component; and

wherein said wiper forms a molded component distinct from said closure component, said wiper comprising a central part forming said swaged part and a lateral part engaging with said lower part of said closure component by a secondary assembly, so as to form an assembly component.

9. A dispenser according to claim 8 wherein said inner channel of said straight skirt has an axial height at least equal to that of said peripheral part, wherein said straight skirt comprises an upper wall forming an axial extension of said straight skirt, said upper wall being located above said peripheral part of said closure component, and wherein said upper wall forms a bowl with said closure component.

10. A dispenser according to claim 9 wherein the outer shell of said applicator has an outer diameter smaller than the diameter of said bowl, whereby when said applicator is screwed into said container, said outer shell of said cap, at its lower part, is able to go back inside said bowl.

11. A dispenser according to claim 8 wherein said inner channel has an axial height equal to that of said peripheral part, wherein said peripheral part of said closure component has an upper edge aligned with said straight skirt at its upper end.

12. A dispenser according to claim 8 wherein said closure component or said peripheral part comprises an outer channel forming an outer shoulder for said straight skirt at its upper end.

13. A dispenser according to claim 12 wherein said outer shell of said cap has an outer cross section which is in the axial extension of that of said straight skirt of said tank when said applicator is screwed into said container.
