Cosmetic applicator with sponge to absorb substance and to prevent leakage thereof

摘要

A cosmetic applicator, comprising a sponge to absorb substance and prevent leakage thereof is provided herein. The sponge having an elastic open-cell of a three-dimensional membrane structure of elastic polymer and is double over molded in combination with the rigid plastic base. The sponge has predefined density enabling to absorb the substance and skin surface having predefined thickness to prevent a spontaneous release of the substance. The substance may be squeezed out of the sponge only when applying pressure on the sponge. A Radio Frequency Identification (RFID) tag is integrated to the rigid plastic base to allow information related storage.

主权项

1. A cosmetic/medical applicator for storing and applying a substance, the applicator comprising:
a sponge having an elastic open-cell three-dimensional membrane structure of elastic polymer covered by a sponge skin surface defining a top surface of the sponge, where a cosmetic or medical substance is injected into the sponge such that the sponge serves as a container to include all of the substance to be used, the substance is provided in a specific amount required for a pre-determined treatment, the sponge having a shape providing a central through-hole; a rigid base bonded to an entire bottom surface of the sponge, such that the rigid base has a shape complementary to the shape of the sponge and provides a bonding surface interfacing with the sponge, a planar bottom surface opposite the bonding surface and a central through-hole of the rigid base being aligned with the central through-hole of the sponge, wherein the rigid base is an integral part of the applicator, and the planar bottom surface is configured to abut against the medical device; and a Radio Frequency Identification (RFID) tag containing information regarding a cosmetic or medical treatment embedded or attached to the rigid base such that the RFID tag is positioned between the bottom surface of the sponge and the planar bottom surface of the rigid base and no portion of the RFID tag extends below the planar bottom surface of the rigid base in a direction away from the sponge, wherein the sponge and the sponge skin surface have a predetermined density and thickness, respectively, sufficient to enable injection of the substance into the sponge while preventing a spontaneous release of the substance, such that a required amount of the substance is squeezed out only when pressure is applied to the sponge.
