Problems solved by technology

When using one side, the side contaminated with sperm will directly contact with the vagina, and the sperm will be directly sent into the vagina, resulting in the failure of the condom for contraception
What's more serious is that if the sexual partner has a genital disease or an infectious disease, if the above situation occurs, it will have an irreversible impact on the other party
[0005] The China Patent Office once published a utility model patent with the application number CN201621155967.8 "a tray that can separate the front and back of condoms", hoping to solve the problem of difficult identification of the front and back of the product through the improvement of the design of a single package, but experiments show that , even if it is reversed, it can still be placed in the tray packaging described in the patent, and it is still unavoidable to avoid human or machine errors during the heat-sealing packaging process.

Embodiment 1

[0031] When the condom product that is easy to identify the front and back is prepared by dipping color coating, it is only necessary to add the process of preparing color coating on the basis of the conventional condom production process of three dipping processes. The specific process is as follows:

[0032] 1. After the condom mold is dipped in the first layer of film 4, leave the glue tank, use hot air to blow the condom to half-dry before dipping in pigment A, and then enter the glue tank mixed with pigment A, the mold is mixed with pigment A In the glue tank, only impregnate the seminal vesicle and the position below the straight cylinder, that is, the seminal vesicle arc part 1, then leave the glue tank, turn over and dry to shape;

[0033] 2. After the condom mold is soaked with the second layer of film 5, leave the glue tank, use hot air to blow the condom until it is half dry before dipping in the pigment B, and then enter the glue tank mixed with the pigment B. The m...

Embodiment 2

[0038] When using the spraying method to prepare condom products with color coatings that are easy to identify the front and back sides, it is only necessary to add the process of preparing color coatings on the basis of the conventional condom production process of the three-time dipping process. The specific process is as follows:

[0039] 1. After the condom mold is dipped in the first layer of adhesive film 4, use hot air to dry the condom adhesive film, and before impregnating the second layer of adhesive film 5, set the effective position of the condom mold at the appropriate station --- The top 2 of the seminal vesicle at the set position in the arc part 1 of the seminal vesicle is sprayed with a uniform quick-drying color coating 7 by spraying equipment, and the color coating can be green, and then dried and shaped;

[0040] 2. After the condom mold is dipped in the second layer of adhesive film 5, use hot air to dry the condom adhesive film, and before dipping the thir...

Abstract

The invention belongs to the technical field of condoms and particularly relates to a condom with easy identification of positive and negative sides. The condom is characterized in that two coatings different in color are attached to the same position of a seminal vesicle region, and coatings of other regions are colors without covering power; in the two color coatings, one coating is located between a first-layer adhesive film and a second-layer adhesive film, the other coating is located between the second-layer adhesive film and a third-layer adhesive film, and the coatings are not directly contacted with the human body; besides, the coatings different color are large in color contrast and easy to identify with normal vision. The original shape of the condom is not changed, both normal double-sided aluminum film packaging and plastic-absorbing aluminum film packaging can be selected, more options are provided for manufacturing enterprises, and production cost is saved; by the arrangement, the problem that the positive and negative sides of the condom cannot be correctly distinguished when an existing condom is taken out from the condom packaging can be well solved.

Description

technical field [0001] The invention belongs to the technical field of condoms, and in particular relates to a condom whose front and back sides can be easily identified. Background technique [0002] The existing condoms are all of the same color, and the packaging method is that the whole condom is thermally synthesized into a plane from top to bottom through two upper and lower aluminum foil films, and the film is sealed around. There is no special method to distinguish the front and back of the condom. When many people use condoms, when they take out the condom from a single packaging bag, they cannot distinguish the front and back of the condom because of the dripping of lubricating oil, and they will wear the condom on the penis in reverse. If you can't unfold it, adjust the side and put it on again. [0003] Some condom manufacturers will associate the front and back of the packaging bag with the front and back of the product itself, and guide consumers when using co...
