Kind of anti-permeability dry and wet multi-functional powder puff
Abstract
The invention discloses a kind of anti-permeability dry and wet multi-functional powder puff. This powder puff includes the main body that is made from closed cell foaming material. The surface of the powder puff forms uniform and dense pores that reduce the permeability characteristic of liquid. The cells of the puff form very tight and seamless links that are non-absorbent and impermeable. The invention solves the problem of existing technology successfully. The powder puff will not absorb cosmetics, such as BB cream, dry powder, toner, eye cream, pre-make-up, makeup base, essence, face cream, emulsion and other cosmetics when using. It also has other advantages such as good flexibility which can make sure that it fits the skin perfectly, no peculiar smell and easy to put on the makeup. The puff can be used continuously after the cosmetic remained on the surface cleaned by wet towel or clean water.
Claims
exact text as granted — not AI-modified1 . The feature of this anti-permeability dry and wet multi-functional powder puff is that the main body is made from closed-hole foaming material which can form uniform and dense pores that reduce the permeability characteristic of liquid.
2 . The feature of the anti-permeability dry and wet multi-functional powder puff stated in claim 1 is the cells of the puff form very tight and seamless links that are non-absorbent and impermeable.
3 . The feature of the anti-permeability dry and wet multi-functional powder puff stated in claim 2 is that the main material of the powder puff is styrene-butadiene rubber.
4 . The feature of the anti-permeability dry and wet multi-functional powder puff stated in claim 2 : the main body of the powder puff is a mixture contains 90% styrene butadiene rubber (SBR) which is the main ingredient and 10% other auxiliary materials. After closed cell foaming, the volume is no longer changing after foaming into a certain degree and becomes a completely solid forming foam. Then sanding the shape with a grinding machine after heating the drying track while pumping air and using cooling functions at low temperature to get rid of the odor.Join the waitlist — get patent alerts
