Abstract

A thermoplastic bottle has a crimped valve cup and a method of manufacturing a thermoplastic bottle includes crimping a valve cup to such a bottle. The thermoplastic bottle and valve cup may be used in a system to dispense aerosol products. At least one protrusion extends from a flange of the bottle to which the valve cup is crimped. Prior to being crimped to the bottle, the valve cup is set to the bottle with an interference fit between a crimping portion of the valve cup and the protrusion. The interference fit prevents shifting of the valve cup from its set position on the bottle prior before the valve cup is crimped.

First claim

We claim:

1. A bottle comprising:
a main body with an open end and a closed end, wherein an axis of the bottle is defined between the open end and the closed end;
a flange positioned (i) adjacent to the open end and (ii) adjacent to a portion of the main body, the flange extending further from the axis of the bottle than the adjacent portion of the main body extends from the axis of the bottle, wherein the flange is configured to contact a structure that is crimped to the flange in such a manner so as to close the open end of the bottle, with the flange retaining the crimped structure to the bottle; and
a plurality of protrusions extending from a circumferential surface of the flange in a direction at least substantially perpendicular to the axis of the bottle, wherein the protrusions are spaced from each other such that a majority of the circumferential surface of the flange does not include protrusions extending therefrom, and
wherein the main body, the flange, and the protrusions are formed from a thermoplastic material.

2. A bottle according to claim 1 , wherein the protrusions extend from about 0.02 mm to about 2 mm outward from the flange.

3. A bottle according to claim 2 , wherein the protrusions extend about 0.1 mm outwards from the flange.

4. A bottle according to claim 1 , wherein the protrusions are positioned symmetrically about the flange.

5. A bottle according to claim 1 , wherein the bottle is configured to be pressure resistant so as to contain an aerosol product under pressure.

6. A bottle according to claim 1 , wherein the flange has an annular shape.

7. A bottle according to claim 1 , wherein the bottle is manufactured using at least one of a blow molding process and an injection molding process.

8. A method of providing a system for dispensing an aerosol composition, the method comprising:
providing a bottle made from a thermoplastic material, the bottle having an open end and a closed end, with an axis of the bottle being defined between the open end and the closed end;
setting a structure adjacent to a flange at one end of the bottle, with an interference fit being formed between the structure and protrusions extending from a circumferential surface of the flange, with the structure substantially closing the open end of the bottle, with the protrusions extending from the flange in a direction at least substantially perpendicular to the axis of the bottle, and with the protrusions being spaced from each other such that a majority of the circumferential surface of the flange does not include protrusions extending therefrom;
crimping the structure to the flange of the bottle; and
providing an aerosol composition in the bottle.

9. The method according to claim 8 , wherein the structure is a valve cup.

10. The method according to claim 8 , wherein the protrusions extend from about 0.02 mm to about 2 mm outward from the flange.

11. The method according to claim 9 , wherein the protrusions are symmetrically positioned about the flange.

12. The method according to claim 8 , wherein the bottle is formed using at least one of a blow molding process and an injection molding process.

13. A bottle comprising:
a main body with an open end and a closed end, wherein an axis of the bottle is defined between the open end and the closed end;
a flange positioned (i) adjacent to the open end and (ii) adjacent to a portion of the main body, the flange extending further from the axis of the bottle than the adjacent portion of the main body extends from the axis of the bottle, wherein the flange is configured to contact a structure that is crimped to the flange in such a manner so as to close the open end of the bottle, with the flange retaining the crimped structure to the bottle; and
a plurality of protrusions extending from a circumferential surface of the flange in a direction at least substantially perpendicular to the axis of the bottle, the protrusions being spaced about the circumferential surface of the flange such that a total length that the protrusions extend about the circumferential surface is less than a total length of the circumferential surface between the protrusions,
wherein the main body, the flange, and the protrusions are formed from a thermoplastic material.

14. A bottle according to claim 13 , wherein the protrusions extend from about 0.02 mm to about 2 mm outward from the flange.

15. A bottle according to claim 14 , wherein the protrusions extend about 0.1 mm outwards from the flange.

16. A bottle according to claim 13 , wherein the protrusions are positioned symmetrically about the flange.

17. A bottle according to claim 13 , wherein the bottle is configured to be pressure resistant so as to contain an aerosol product under pressure.

18. A bottle according to claim 13 , wherein the flange has an annular shape.

19. A bottle according to claim 13 , wherein the bottle is manufactured using at least one of a blow molding process and an injection molding process.
