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

Abstract

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.

         20 . A cosmetic/medical applicator configured to be connected to a medical device for storing and applying a substance, the applicator comprising:
 a sponge injected with a substance having an elastic open-cell of a three-dimensional membrane structure of elastic polymer covered by a sponge skin surface, serving as a container to include all of the substance to be used, including a specific amount of the substance required for a pre-determined treatment;   a rigid base bonded to the sponge, covering an entire bottom surface of the sponge, wherein the rigid base is not part of the medical device; and   a Radio Frequency Identification (RFID) tag integrated or attached to the rigid base,   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 or absorption of the substance, such that when applying pressure on the sponge, a required amount of the substance is squeezed out.   
     
     
         21 . The applicator according to  claim 20 , wherein the skin surface of the sponge is flat. 
     
     
         22 . The applicator according to  claim 20 , wherein the sponge has a hollow cavity to enable insertion of functional treatment components. 
     
     
         23 . The applicator according to  claim 20 , wherein the predefined density of the sponge is similar to absorption capacity of cosmetic or medical substances including at least one of oil and water in a range between 5 cc and 7 cc. 
     
     
         24 . The applicator according to  claim 20  wherein the density of the sponge material after the molding process is between 40 to 250 Kg/m3. 
     
     
         25 . The applicator according to  claim 20 , wherein the RFID tag is integrated during the over molding of the sponge with the rigid plastic base. 
     
     
         26 . The applicator according to  claim 20 , wherein the RFID tag is initially bonded to the rigid base. 
     
     
         27 . The applicator according to  claim 20  wherein the sponge is double over molded in combination with the rigid plastic base. 
     
     
         28 . The applicator according to  claim 25 , wherein the bonded RFID tag and the rigid base are integrated through an over molding process in which thermoplastic elastomers are injected into a mold at predefined temperature to yield the cosmetic applicator including the sponge having three dimensional structure bonded to the rigid base and encapsulating an RFID tag. 
     
     
         29 . The applicator according to  claim 20 , wherein control on level of viscosity of the substance is enabled by pressing on different spots in the sponge. 
     
     
         30 . The applicator according to claim  1 , wherein information regarding a cosmetic treatment is stored in the RFID tag that is integrated in the applicator. 
     
     
         31 . The applicator according to  claim 29 , wherein the information that is stored is at least one of: (i) type of treatment; (ii) expiration date of the substance; and (iii) length of treatment. 
     
     
         32 . The applicator according to  claim 29 , wherein the information that is stored is at least one of: encryption code, association code to medical device of different equipment provider, expiration date or manufacturing dates 
     
     
         33 . The applicator according to  claim 29 , wherein the RFID tag maintains information which is updated during the treatment process. 
     
     
         34 . The applicator according to  claim 33  wherein the updated information is calculated by the RFID chip. 
     
     
         35 . The applicator according to  claim 33  wherein the updated information is received from a medical device associated with said applicator. 
     
     
         36 . The applicator according to  claim 20  wherein the applicator is designed to be connected to a medical device. 
     
     
         37 . A method to manufacture an applicator for applying a substance, the method comprising the steps of:
 bonding a Radio Frequency Identification (RFID) tag to a rigid base;   integrating the bonded RFID and the rigid base through a double over molding process; and   injecting thermoplastic elastomers into a mold at a predefined temperature to yield the applicator with a sponge having a three dimensional structure bonded to the rigid base and encapsulating the RFID tag.   
     
     
         38 . The method of  claim 37  wherein the bonding stage is processed by using flip-chip bonding technology. 
     
     
         39 . A method for providing cosmetic or medical treatment using an applicator, comprising a sponge, rigid base and RFID including treatment data, the method comprising the step of:
 maintaining a substance material before treatment contained within the sponge, wherein the sponge has an elastic open-cell of a three-dimensional membrane structure of an elastic polymer;   squeezing a required amount of the substance out of the sponge by applying pressure on the sponge, wherein the sponge has a predefined density and thickness enabling the sponge to contain part of the substance, while releasing the required amount of substance, preventing usage of an excessive amount of the substance.
