However, if the consumer does not fully extend the lipstick (which often happens when using a new lipstick), the locking track will not work because the elevator bucket is not fully extended to engage in the locking track

Embodiment Construction

[0019] Referring now to FIGS. 1-8, where like parts have been given like reference numerals, an improved cosmetic dispenser for sunscreen-containing cosmetics is indicated generally at 20 . The dispenser 20 includes a cam sleeve 30 , an inner body 50 and an elevator bucket 100 .

[0020] The inner body 50 is preferably molded from a plastic material, such as polypropylene or other material, chosen to have a low coefficient of friction and to be compatible with the composition of the cosmetic stick within the dispenser. The cam sleeve is preferably made of high impact styrene. The combination of the above two plastics can provide the consumer with the best feeling of rotational traction because there is a minimum of static friction between the two different plastics, thereby providing a smooth action. without sticky feeling. However, it is possible to use high-impact styrene for both components.

[0021] The cam bush 30 is rigid and tubular, having an upper portion 32 and a ...

Abstract

A lipstick or cosmetic dispenser having a tubular cam sleeve and an innerbody fitted inside the cam sleeve, and internal helical tracks supporting an elevator cup. The cam sleeve has a lower cam skirt with a plurality of ribs provided on its inner wall. The innerbody has a beveled shoulder around a lower outer wall thereof. The cam skirt ribs bear against the beveled shoulder to create frictional drag between the innerbody and the cam sleeve, and to cause the cam sleeve to be urged upwardly. The ribs on the inner wall of the cam skirt extend at an angle relative to a centerline of said dispenser, and preferably are angled the same direction as the internal helical tracks of the cam sleeve. There are from three to seven, preferably, five or six of said ribs located equidistantly from each other around said inner wall of said cam skirt. The ribs may be connected with each other by webs or separated by slots.

Description

technical field [0001] The present invention relates to the field of dispensers having an extension and retraction mechanism for cosmetics, especially lipsticks, face creams and other cosmetics. Background technique [0002] There has been a tendency in the cosmetics market for cosmetics to contain sunscreens. These sunscreen containing cosmetics present some problems in operating the extension and retraction mechanisms of stick dispensers such as lipstick dispensers. Sunscreen ingredients such as methoxycinnamate can damage dispenser components made of styrene. [0003] It is desirable that cosmetic dispensers should have sufficient rotational traction to impart a smooth and luxurious feel to the dispenser. It would be better to provide the feeling that no lubricant is applied to the dispenser mechanism, as these could inadvertently alter or contaminate the makeup or lip balm; moreover, the lubricant would add additional manufacturing costs, which would be best eliminated...
