Abstract

A device for dispensing oblong objects comprising: (i) a main dispensing opening for allowing the objects to be dispensed to pass therethrough one by one; (ii) at least one other opening of elongate shape, one of whose sides opens into the main dispensing opening, the elongate opening having an opening width equal to or greater than a minimum thickness of the object to be dispensed; and (iii) guide surfaces for guiding the objects to be dispensed. The guide surfaces lie along front sides of the elongate opening and face the objects to be dispensed, so as to collect and guide the objects toward at least one of the elongate openings.

Claims

1. A device for dispensing oblong objects comprising:

a main dispensing opening for allowing the objects to be dispensed to pass therethrough one by one;

at least one other opening of elongate shape, one of whose sides opens into the main dispensing opening, the elongate opening having an opening width equal to or greater than a minimum thickness of the object to be dispensed; and

guide surfaces for guiding the objects to be dispensed, said surfaces lying along front sides of the elongate opening and facing the objects to be dispensed, so as to collect and guide said objects to be dispensed toward at least one of the elongate openings.

2. The device as claimed in claim 1, comprising at least two elongate openings arranged radially with respect to an axis of the main dispensing opening.

3. The device as claimed in claim 1, wherein the elongate opening or openings have the shape of slots.

4. The device as claimed in claim 3, wherein the slot-shaped elongate opening or openings have at least one of their sides curved, or two symmetrically curved sides, the curved sides forming a restriction.

5. The device as claimed in claim 1, wherein the elongate opening or openings are slots of substantially constant width.

6. The device as claimed in any claim 1, wherein the elongate opening or openings are slots whose width increases toward the main dispensing opening.

7. The device as claimed in claim 1, wherein the elongate openings have a length at least equal to twice the width of the objects to be dispensed.

8. The device as claimed in claim 1, wherein the main dispensing opening is a circular opening , the diameter of which approximates a minimum width of the objects to be dispensed.

9. The device as claimed in claim 1, wherein the rim of at least one of the openings includes at least one portion made of elastic material, said portion being intended to allow an object dispensed to be held in the opening by being lightly gripped therein.

10. The device as claimed in claim 9, wherein the elastic material is selected from the group consisting of:

natural rubbers, mono-olefin olefin rubbers, isobutylene/isoprene, ethylene/vinyl acetate (EVA), ethylene-propylene (EPR), ethylene-propylene-diene monomer (EPDM), ethylene/acrylic ester (EMA-EEA) polymers;

fluoropolymers;

diolefin rubbers, polybutadienes, butadiene-styrene (SBR) copolymers, rubbers based on condensation products, polyester and polyurethane thermoplastic rubbers, silicones, styrene rubbers, styrene-butadiene-styrene (SBS) and styrene-isoprene-styrene (SIS) rubbers.

11. The device as claimed in claim 1, comprising the form of a disk.

12. The device as claimed in claim 1, wherein the guide surfaces for guiding the objects to be dispensed are made of rigid material, allowing sliding of the objects to be dispensed.

13. The device as claimed in claim 1, wherein the rigid material constituting the guide surface is at least selected from the group consisting of polyethylenes, polypropylenes, ethylene/propylene copolymers and blends thereof;

polyamides;

polystyrenes (PS);

acrylonitrile-butadiene-styrene (ABS) copolymers and styrene-acrylonitrile (SAN) copolymers;

polymethyl methacrylates (PMMA);

polyethylene terephthalates (PET);

polyvinyl chlorides; and

polycarbonates.

14. The device as claimed in claim 1, wherein the dispensed objects are identical to one another and are in the form of parallelepipedal strips or stems of elliptical, polygonal or circular cross section.

15. A container for containing objects to be dispensed and having at least one opening into which the dispensing device of claim 1 is mounted.

16. The object-dispensing container as claimed in claim 15, wherein the dispensing device is assembled inside the container.

17. The object-dispensing container as claimed in claim 16, wherein the dispensing device is assembled with the container by assembly of a conical force-fitting, screwing, zip-fastening or adhesive bonding type.

18. The dispensing container as claimed in claim 15, wherein the container is closed off in a sealed manner by a removable stopper.

19. The container as claimed in claim 18, wherein the stopper is articulated to the container via a hinge, an axis of which is approximately perpendicular to an axis of the container.

20. The container as claimed in claim 15, formed from at least one thermoplastic polymer material selected from the group consisting of polyethylenes, polypropylenes, ethylene/propylene copolymers and blends thereof;

polyamides;

polystyrenes (PS);

acrylonitrile-butadiene-styrene (ABS) copolymers and styrene-acrylonitrile (SAN) copolymers;

polymethyl methacrylates (PMMA);

polyethylene terephthalates (PET);

polyvinyl chlorides; and

polycarbonates.

21. The container as claimed in claim 15, including at least one desiccating element.

22. The container as claimed in claim 21, wherein the desiccating element is selected from the group consisting of desiccating inserts placed in the container, and desiccating layers molded onto an internal surface of the container and/or of the stopper.

23. The container as claimed in claim 21, wherein the desiccating element constitutes walls of the container and/or of the stopper.

24. The container as claimed in of claim 21, wherein the desiccating element comprises (i) desiccating compositions formed from blends of thermoplastic polymers and/or copolymers and (ii) mineral desiccants.

25. The container as claimed in claim 24, wherein the thermoplastic polymers and/or copolymers forming the desiccating element are selected from those forming said container, taken by themselves or as a blend, optionally combined with at least one elastomer used for producing elastic contact regions of the elongate openings.

26. The container as claimed in claim 21, wherein the desiccants used in the composition of the desiccating elements are selected from the group consisting of anhydrous metal salts, metal oxides that can react with water vapor, silica gels, molecular sieves, starch, montmorillonite, polybutadienes and polysiloxanes.

27. A container that is assembled with a device defined by claim 1, wherein said container forms an assembly for the storage and dispensing of oblong objects.

28. A device of claim 1 wherein said objects have a substantially polygonal, circular, elliptical or associated cross section.
