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.
Claims20
A method for providing a cosmetic or medical applicator for cosmetic or medical treatment, the method comprising
- providing the applicator, comprising a sponge and a rigid base;
- injecting a substance into the sponge through a skin surface of the sponge, the skin surface of the sponge having 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 and while permitting a required mount of the substance to be released out of the sponge only upon application of pressure on the sponge, thereby preventing usage of an excessive amount of the substance;
- and
- maintaining the substance before treatment contained within the sponge without spontaneous release or absorption of the substance.
A method to manufacture a cosmetic or medical applicator configured to be connected to a cosmetic or medical device for storing and applying a substance, the applicator comprising:
- a sponge including a substance, wherein the sponge is an open-cell sponge having a three-dimensional membrane structure made of a thermoplastic elastomer, the sponge having a skin surface of a predetermined thickness sufficient to prevent a spontaneous release of the substance;
- and
- a rigid plastic base integrally connected to a side of the sponge, and covering a bottom surface of the sponge,
- the method comprising:
- injecting the thermoplastic elastomer into a mold through an over molding process at a predefined temperature to yield the applicator having the sponge having the three-dimensional structure integrated to the rigid base.
A method for providing cosmetic or medical treatment using an applicator comprising a sponge, a rigid base, and a Radio Frequency Identification (RFID) tag including treatment data, the method comprising:
- maintaining a substance before treatment contained within the sponge;
- 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 a required amount of substance, preventing usage of an excessive amount of the substance.
