Abstract

An internally supplied applicator for applying a fluid substance, in particular a cosmetic or pharmaceutical product, having a solid finger support with preferably injection molded fingers and at least one supply conduit for conveying the substance from the side of the finger support oriented away from the fingers to the side of the finger support that is equipped with the fingers; the side of the finger support oriented away from the fingers is adjoined by a (crushable) foil packet that contains a reservoir of the substance that is to be applied so that pressing on the foil packet causes a volume of the substance, which is to be applied, to be dispensed through the supply conduit.

First claim

The invention claimed is:

1. An internally supplied applicator for applying a fluid substance, in particular a cosmetic or pharmaceutical product, comprising:
a solid finger support with a plurality of injection molded fingers and at least one supply conduit for conveying the substance from a side of the finger support oriented away from the fingers to a side of the finger support that is equipped with the fingers; wherein the side of the finger support oriented away from the fingers is adjoined by a crushable foil packet that contains a reservoir of the substance that is to be applied so that pressing on the foil packet causes a volume of the substance, which is to be applied, to be dispensed through the supply conduit.

2. The internally supplied applicator according to claim 1 , wherein the linger support is intrinsically rigid.

3. The internally supplied applicator according to claim 1 , wherein the foil packet is welded only to a circumference surface of the finger support.

4. The internally supplied applicator according to claim 1 , wherein the foil packet is a tubular foil that is extruded or blown so that it is seamless around its outer circumference direction and has a all thickness of at most 0.5 mm.

5. The internally supplied applicator according to claim 4 , wherein the tubular foil is intrinsically welded at an end oriented away from the finger support.

6. The internally supplied applicator according to claim 4 , wherein the finger support is composed of a finger-supporting plate, which on its side oriented away from the fingers, transitions integrally into a tubular fitting that the tubular foil encompasses like a stocking.

7. The internally supplied applicator according to claim 6 , wherein the foil packet or the tubular foil is welded to the outer circumference of the tubular fitting.

8. The internally supplied applicator according to claim 6 , wherein the tubular fitting tapers toward its end oriented away from the finger support and is embodied in a conical shape.

9. The internally supplied applicator according to claim 6 , wherein the finger support or its tubular fitting transitions into at least two spreading arms.

10. The internally supplied applicator according to claim 4 , wherein the foil packet or the tubular foil is welded to the outer circumference of the finger-supporting plate.

11. The internally supplied applicator according to claim 1 , wherein the bristle support is embodied in the shape of a boat.

12. The internally supplied applicator according to claim 1 , wherein the finger support has a thread for screwing on a screw cap or has a snap element for snapping on a cap.

13. The internally supplied applicator according to claim 4 , wherein the tubular foil also encompasses the finger support at its finger end and is intrinsically welded to its end there.

14. An applicator unit composed of at least one applicator according to claim 1 , wherein the applicator is inserted into a blister pack, which is composed of a tray that has a recess that accommodates the applicator and at least the recess that accommodates the applicator is sealed on one side with a foil.

15. An internally supplied applicator for applying a fluid substance, in particular a cosmetic or pharmaceutical product, comprising:
a static finger support with a plurality of fingers injection molded onto the static finger support and at least one supply conduit for conveying the substance from a side of the finger support oriented away from the fingers to a side of the finger support that is equipped with the fingers; wherein the side of the finger support oriented away from the fingers is adjoined by a crushable blister pack, which is composed of a tray and a foil that seals the tray, and which contains a reservoir of the substance that is to be applied; and wherein pressing on the tray and/or the foil that seals the tray causes a volume of the substance, which is to be applied, to be dispensed through the supply conduit.

16. The internally supplied applicator according to claim 15 , wherein the tray and the foil that seals the tray are welded to the finger support.

17. The internally supplied applicator according to claim 15 , wherein the finger support divides the tray into a dry region and a wet region, and the dry region accommodates the plurality of fingers of the finger support; the tray has a predetermined breaking point in the dry region, which makes it possible, before use, to break off a part of the tray that protects the plurality of fingers until the use, and to completely remove the part of the tray or move the part of the tray out of the way so that the application can be carried out with the aid of the plurality of fingers.

18. The internally supplied applicator according to claim 15 , wherein the finger support divides the tray into a dry region and a wet region and the dry region accommodates the plurality of fingers of the finger support; and in the dry region, the tray is sufficiently thin-walled so that the tray can be laterally folded over so that the application can be carried out with the aid of the plurality of fingers.

19. A method for producing the applicator of claim 1 , comprising:
blowing, extruding, or welding a tubular foil;
at least partially sliding a finger support that is equipped with a plurality of injection molded fingers into the tubular foil and then welded the finger support to the tubular foil;
subsequently filling the tubular foil with a fluid substance, in particular a cosmetic or pharmaceutical product substance, to be applied; and then welding the tubular foil completely closed.

20. The method according to claim 19 , comprising inserting the finger support into a beginning of the tubular foil and welding the finger support to the tubular foil before an entire length of the tubular foil that is required for this applicator is blown and/or extruded.

21. The method according to claim 19 , comprising dispensing the substance to be applied into the tubular foil while the latter is still at a temperature of at least 60°.
