Abstract

A wiper for use in a cosmetics bottle fabricated from a semi-rigid plastic such as low density polyethylene. The wipe has a sleeve with an integral wiper diaphragm defining an orifice having a wiper edge. The wiper diaphragm is connected to the sleeve by a plurality of spaced-apart ribs which act to hold any pieces of the diaphragm which may break off in use, and prevent them from falling into the cosmetics bottle and any product contained in the bottle.

Claims

1. A wiper for use in a cosmetics bottle having a neck and an applicator rod and applicator, the wiper removing excess cosmetics from the applicator rod and applicator as they are withdrawn through the neck of the container, the wiper comprising:

an low density polyethylene sleeve having an inner wall and a outer wall, said outer wall of said sleeve being tightly fittable in the cosmetics bottle neck, said sleeve having an integral wiper diaphragm extending radially inwardly from said inner wall of said sleeve at a lower end thereof, said wiper diaphragm being formed as a downwardly and inwardly extending curved surface terminating in a wiper edge defining a wiper orifice, said wiper diaphragm being connected to said sleeve by a plurality of spaced-apart ribs extending at an angle upwardly and outwardly from said wiper edge of said wiper diaphragm to said inner wall of said sleeve, said wiper edge having a thickness of about 0.015 inches or less.

2. The wiper of claim 1, wherein said sleeve has a radial lip extending outwardly from an upper end thereof.

3. The wiper of claim 1, said wiper edge having a thickness of about 0.008 inches or less.

4. A wiper for use in a cosmetics bottle having a neck and an applicator rod and applicator, the wiper removing excess cosmetics from the applicator rod and applicator as they are withdrawn through the neck of the container, the wiper comprising:

a sleeve, fabricated from a semi-rigid plastic, having an inner wall and a outer wall, said outer wall of said sleeve being tightly fittable in the cosmetics bottle neck, said sleeve having an integral wiper diaphragm extending radially inwardly from said inner wall of said sleeve at a lower end thereof, said wiper diaphragm having an orifice having a wiper edge, said diaphragm being formed as a downwardly and inwardly extending curved surface terminating in said wiper orifice, said wiper diaphragm being connected to said sleeve by a plurality of spaced-apart ribs.

5. The wiper of claim 4, said wiper diaphragm tapering in thickness from a thicker first end adjacent said sleeve to said wiper edge which is thinner than said thicker first end.

6. The wiper of claim 4, said ribs extending upwardly and outwardly from said wiper diaphragm to said inner wall of said sleeve.

7. The wiper of claim 4, wherein said sleeve has a radial lip extending outwardly from an upper end thereof.

8. The wiper of claim 4, said wiper edge having a thickness of about 0.015 inches or less.

9. The wiper of claim 8, said wiper edge having a thickness of about 0.008 inches or less.

10. A cosmetics container assembly comprising:

a bottle having a chamber for containing cosmetics, the bottle having a neck;

a cap removably secured to the neck, the cap having an applicator rod, having a rod diameter, for extending through the neck into the chamber, and an applicator, having a maximum applicator diameter, at the distal end of the rod for carrying cosmetics from the chamber upon removal of the cap, applicator rod and applicator from the bottle;

a sleeve fabricated from a semi-rigid plastic, said sleeve having an inner wall and a outer wall, said outer wall of said sleeve being tightly fittable in said bottle neck, said sleeve having an integral wiper diaphragm extending radially inwardly from said inner wall of said sleeve at a lower end thereof, said wiper diaphragm having an orifice having a wiper edge, said diaphragm being formed as a downwardly and inwardly extending curved surface terminating in said wiper orifice, said wiper diaphragm being connected to said sleeve by a plurality of spaced-apart ribs, said wiper orifice having an orifice diameter, said orifice diameter being less than said rod diameter and less than said maximum applicator diameter, said wiper edge having a thickness such that said wiper diaphragm resiliently deforms to seal around said applicator rod and said wiper edge wipes said applicator rod when it is withdrawn from the bottle, and further said wiper diaphragm resiliently deforms to wipe said applicator when it is withdrawn from the bottle.

11. The cosmetics container assembly of claim 10, said wiper diaphragm tapering in thickness from a thicker first end adjacent said sleeve to said wipe edge which is thinner than said thicker first end.

12. The cosmetics container assembly of claim 10, said ribs extending upwardly and outwardly from said wiper diaphragm to said inner wall of said sleeve.

13. The cosmetics container assembly of claim 10, wherein said sleeve has a radial lip extending outwardly from an upper end thereof.

14. The cosmetics container assembly of claim 10, said wiper edge having a thickness of about 0.015 inches or less.

15. The cosmetics container assembly of claim 14, said wiper edge having a thickness of about 0.008 inches or less.

16. A cosmetics container assembly comprising:

a bottle having a chamber for containing cosmetics, the bottle having a neck;

a cap removably secured to the neck, the cap having an applicator rod, having a rod diameter, for extending through the neck into the chamber, and an applicator, having a maximum applicator diameter, at the distal end of the rod for carrying cosmetics from the chamber upon removal of the cap, applicator rod and applicator from the bottle;

a sleeve fabricated from low density polyethylene, said sleeve having an inner wall and a outer wall, said outer wall of said sleeve being tightly fittable in said bottle neck, said sleeve having an integral wiper diaphragm extending radially inwardly from said inner wall of said sleeve at a lower end thereof, said wiper diaphragm having an orifice having a wiper edge having a thickness of about 0.015 inches or less, said diaphragm being formed as a downwardly and inwardly extending curved surface terminating in said wiper orifice, said wiper diaphragm being connected to said sleeve by a plurality of spaced-apart ribs, said ribs extending at an angle upwardly and outwardly from said wiper edge of said wiper diaphragm to said inner wall of said sleeve, said wiper orifice having an orifice diameter, said orifice diameter being less than said rod diameter and less than said maximum applicator diameter, said wiper edge having a thickness such that said wiper diaphragm resiliently deforms to seal around said applicator rod and said wiper edge wipes said applicator rod when it is withdrawn from the bottle, and further said wiper diaphragm resiliently deforms to wipe said applicator when it is withdrawn from the bottle.

17. The cosmetics container assembly of claim 16, said wiper edge having a thickness of about 0.008 inches or less.
