Problems solved by technology

But it has the following problems: (1) The dry hydrophilic material obviously needs liquid to become lubricant again, there is no other liquid between the inner surface of the condom and the penis except semen, and the inventors use saliva to dissolve the hydrophilic materials; (2) condoms are unstable to all organic solvents, and the use of organic solvents may reduce the safety performance of condoms
This invention has the following problems: (1) the lack of lubricant on the inner surface causes difficulty in wearing and adjustment; (2) the finished condom must be rolled up, which will rupture the microcapsule wall and release the active substance in advance
The results show that the condom with no lubricant on the inner surface will not be loose and feel better when used; however, 46 volunteers reported that it is easy to form an inappropriate gap between the skin of the penis and the mantle when wearing it. Fit (such as skin folds, mantle folds, too tight or too loose, improper alignment, etc.), these improper fits are difficult to correct directly by means of finger pushing and equalization, and the worn part can only be rolled back carefully correct later

Embodiment Construction

[0046] The present invention will be further described below in conjunction with specific examples.

[0047] The raw materials used in this example are commercially available conventional products. The water-based lubricant in the following examples is self-made, and the silicone oil lubricant is purchased from Hangzhou Sizhou Chemical Co., Ltd.; Carbomer 941 is purchased from Qingdao Tianliyuan Biotechnology Co., Ltd.

[0048] 1. Quantitative lubricating condom lubricating effect test (such as figure 1 As shown, the area of ​​the lubricant layer provided on the inner surface of the condom is 100% of the inner surface area of ​​the condom)

[0049] Take a batch with a width of 52mm and an inner surface area of ​​188cm 2 The conventional condom is divided into 30 groups (including embodiment 1-1~12-1, embodiment 1-2~12-2, and contrast group 1-1~3-1, contrast group 1-2~3-2 ), every group of 20, the silicon oil lubricant layer (embodiment 1- 1~12-1, comparison group 1-1~3-1) ...

Abstract

The invention relates to a condom capable of achieving quantitative lubrication. The condom is characterized in that a lubricant layer is disposed on the inner surface of the condom, the lubricant layer contains lubricant with the unit dose of 0.011-0.319mg / cm<2>, and the area of the lubricant layer is 50-100% of the area of the inner surface of the condom. The condom has the advantages that loosening and sliding of the condom can be prevented effectively, user satisfaction during use is increased, the condom is easy to wear, inappropriate fit (such as skin wrinkles, excessive tightness or excessive looseness and irregularity) of the penis skin and the condom is avoided, wearing satisfaction is improved, and consumers' willingness to use the condom can be increased.

Description

technical field [0001] The invention relates to a contraceptive tool for men, in particular to a quantitative lubricating condom. Background technique [0002] The male condom consists of three parts, the ring, the mantle and the closed end, which are divided into an inner surface (in contact with the male penis) and an outer surface (in contact with the female vagina). In order to facilitate the wearing of the user and improve the satisfaction during use, the condom generally needs to be moderately lubricated. [0003] The existing lubrication method of the condom is: the condom is automatically rolled up from the ring end to the closed end, and then a lubricant (water-based lubricant or silicone oil lubricant is added to the closed end of the rolled condom, the additive amount is usually 300 ~ 1000mg), and finally sealed into the packaging film and put into a sales box. During the transportation and storage of the condom, a small part of the lubricant gradually penetrate...
