Abstract

(57) [Summary] [Purpose] To provide a condom for immobilizing semen. [Structure] A jelly agent 2 containing a superabsorbent resin such as vinyl acrylate alcohol copolymer or sodium polyacrylate as a main component is applied and adhered to the inner surface of the condom body A or its semen reservoir 1. is there.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a condom having a high contraceptive effect.

[0002]

[Prior art]

 Conventionally, condoms with spermicidal agents are well known, but these were merely to attach spermicidal agents to exert a spermicidal effect.

[0003]

[Problems to be solved]

 The present invention does not exert a spermicidal effect, but immobilizes sperm promptly and prevents leakage.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of such circumstances, and its means is to use a jelly containing a super absorbent polymer such as vinyl acrylate vinyl alcohol copolymer or sodium polyacrylate as a main component in the condom body or It was applied to the inner surface of the semen reservoir.

[0005]

[Action]

 In the present invention, sperm are fixed by a jelly agent containing a super absorbent polymer as a main component.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The condom body A has a well-known form in this technical field, and a film is formed by immersing a molding die in a colored transparent or colorless natural rubber latex solution. A known lubricant such as silicone oil or polyethylene glycol is attached to the inner surface or the outer surface or both the inner surface and the outer surface, and a vinyl alcohol acrylate copolymer, sodium polyacrylate, etc. is attached to the semen reservoir 1 at the tip. A jelly agent 2 containing a super absorbent polymer as a main component is applied and attached.

The jelly agent 2 is a jelly-like substance containing a superabsorbent resin such as vinyl acrylate vinyl alcohol copolymer or sodium polyacrylate as a main component, and its dispersion medium is silicone oil, glycerin, polyethylene glycol or the like. It is optional to use, and its viscosity is 500 to 30,000 cps, and this jelly agent 2 is applied to and adheres to the semen reservoir 1 at the tip of the condom body A. The amount of jelly agent 2 per condom body is about 20 mg of the super absorbent resin added to 20 mg of the above dispersion medium. A super absorbent polymer is a polymer that absorbs several tens to several thousand times its own weight of water and retains it for a long period of time, swells in water to form a hydrogel, and its structure is ionic. Since the chains of the electrolyte polymer, which is inherently water-soluble, are loosely cross-linked, they are composed of an ionic network of polyelectrolytes, ions of the ions, and water entrapped in the network.

[0008] Next, to describe specific embodiments, the compounding recipe is silicon oil 20 mg, sodium polyacrylate 20 mg (water-absorbent resin manufactured by Sumitomo Seika; AquaKeep 4S, particle size 5 to 20 μ) in total. 40 mg Generally, the semen amount of a normal person was 5000 mg, the water absorption amount was 300 cc / g, the theoretical value was 17 mg / 5 cc, and the semen solidification rate was 15 seconds or less.

[0009]

【effect】

 In the present invention, a jelly containing a superabsorbent resin such as vinyl acrylate vinyl alcohol copolymer or sodium polyacrylate as a main component is applied to the inner surface of the condom body or the semen reservoir, so that semen can be immediately obtained after ejaculation. It can be fixed, and there is no risk of leakage to the outside of the condom body. In addition, various physical properties can be provided without any abnormalities, and safe and excellent products can be provided, and a condom with a desired effect, that is, a high contraceptive effect can be obtained.
