Abstract

A cosmetic dispenser includes a translucent reservoir sandwiched in-between a shelled wall and a solid wall of an opaque housing. The shelled wall provides exposure to a portion of the translucent reservoir, the exposed portion of the translucent reservoir defines a flexible wall. The translucent reservoir being formed of a substantially more supple material than the opaque housing, thereby providing the flexible wall to displace a portion of product stored in the translucent reservoir.

Claims

1. A cosmetic dispenser comprising:

a housing having a shelled wall opposite an inflexible solid wall;

a flexible reservoir sandwiched between the shelled wall and the inflexible solid wall of the housing, the shelled wall for providing exposure to a portion of the flexible reservoir, the exposed portion of the flexible reservoir defining a flexible wall for displacing a portion of a product stored in the flexible reservoir; and

an inflexible collar fixed distal to the housing, the inflexible collar containing the flexible reservoir in the housing.

2. The cosmetic dispenser of claim 1, wherein the housing is opaque and the flexible reservoir is translucent.

3. The cosmetic dispenser of claim 2, wherein the housing is made of a material different than a material of the flexible reservoir.

4. The cosmetic dispenser of claim 2, wherein the housing comprises terpolymer, polypropylene (PP), acrylonitrile butadiene styrene (ABS), or styrene acrylonitrile (SAN).

5. The cosmetic dispenser of claim 2, wherein the flexible reservoir comprises terpolymer.

6. The cosmetic dispenser of claim 1, further comprising:

an application tip securely disposed to the inflexible collar, the application tip having a stem interconnected with the flexible reservoir, the stem for transporting the displaced portion of the product stored in the flexible reservoir to the application tip; and

a cap removably coupled to the inflexible collar and encapsulating the application tip.

7. The cosmetic dispenser of claim 1, wherein the housing is generally pouch-shaped.

8. The cosmetic dispenser of claim 7, wherein the cap is substantially the same shape as the generally pouch-shaped housing.

9. The cosmetic dispenser of claim 1, wherein the flexible reservoir is generally pouch-shaped.

10. The cosmetic dispenser of claim 9, wherein the flexible reservoir is substantially clear.

11. The cosmetic dispenser of claim 9, wherein the flexible reservoir is tinted.

12. The cosmetic dispenser of claim 9, wherein the flexible reservoir is opaque.

13. The cosmetic dispenser of claim 1, wherein the flexible reservoir is generally tubular shaped.

14. A dispenser housing comprising:

a reservoir for storing a cosmetic product;

a shelled wall opposite a solid wall, the shelled wall and the solid wall forming a single unit having a cavity to contain the reservoir, the shelled wall for providing exposure to a portion of the reservoir, the exposed portion of the reservoir defining a flexible wall for displacing a portion of a product stored in the reservoir; and

a collar fixed distal to the single unit containing the reservoir in the cavity.

15. The dispenser housing of claim 14, wherein the reservoir is generally pouch-shaped and is formed by an extrusion blow molded (EBM) process.

16. The dispenser housing of claim 14, wherein the reservoir is generally tubular shaped and is formed by a multilayer profile extrusion/co-extrusion process.

17. The dispenser housing of claim 14, wherein the collar is fixed distal to the single unit via ultrasonic welding.

18. The dispenser housing of claim 14, wherein the collar is connected to the single unit via a living hinge.

19. A method comprising:

sandwiching a translucent reservoir formed of a first material in-between a shelled wall and a solid wall of an opaque housing formed of a second material different than the first material, the opaque housing having a cavity defined by the shelled wall opposite the solid wall; and

fixing a collar distal to the opaque housing containing the translucent reservoir in the cavity.

20. The method of claim 19, wherein the first material comprises terpolymer.

21. The method of claim 19, wherein the second material comprises terpolymer, polypropylene (PP), acrylonitrile butadiene styrene (ABS), or Styrene Acrylonitrile (SAN).

22. The method of claim 19, wherein the fixing of the collar distal to the opaque housing comprises ultrasonic welding of the collar to the opaque housing.
