First Claim
Patent Images
1. A cosmetic dispenser comprising:
- a lower valve having a reservoir for containing a product, the lower valve having at least one aperture;
a flow-through gasket disposed at a mouth of the lower valve, the flow-through gasket comprising at least one aperture;
an upper valve coupled to the lower valve and to the flow-through gasket, the upper valve having at least one aperture;
the lower valve, the flow-through gasket, and the upper valve being selectively rotatable in a spiral motion between;
i) an upward position for the dispenser to deliver the product, andii) a downward position to store the dispenser; and
an applicator coupled to the upper valve for applying the product.

Abstract
A dispenser includes a flow-through gasket and a lower valve having a reservoir for containing a product. The flow-through gasket has at least aperture to provide a product delivery passage when the dispenser is selectively rotatable along a helical guide slot to a raised position. When the dispenser is selectively rotatable along the helical guide slot to a retracted position, the dispenser is in a stored state. In some examples, the flow-through gasket may be made of a material having elastomeric properties.
