发明名称 Condom and production method thereof
摘要 [Problem to be solved] In the case where the conventional condom is used, even if it is coated with a lubricant, the surface of the penis as the male organ remains virtually kept in contact with the inside surface of the condom, and the lubricity between them is insufficient. So, since the slip that can occur between them is very slight, the physical stimulation to the penis is limited, and the condom cannot satisfy the sexual desire of the wearer. [Solution] This invention proposes a condom 1 formed of a hydrophobic material, comprising a hydrophilic portion 3 formed on its inside surface on its tip side excluding its base side. The ratio of the length 1 of the hydrophilic portion to the overall length L of the condom excluding the small pocket formed for the semen to get collected at the tip of the condom can be set in a range of 20 to 80%, but if it is set in a range of 25 to 45%, a good balance can be achieved between the enhancement of lubricity and the effect of preventing slipping-off.
