Description

[Detailed Description of the Invention] The present invention relates to a condom, and particularly to a condom for use at the tip.

Conventional tip-attached condoms are attached using the constriction between the glans and the penis.

The means for attaching and fixing it is to tighten the tip of the penis by making the root thinner. Specifically, various proposals have been made, such as making the root part into a thin tube shape and forming a belt to tighten the penis.

However, with this conventional configuration, it is difficult to maintain a proper wearing state regardless of whether the male genitalia is expanding or contracting, and it has been impossible to fully perform the contraceptive function.

In other words, this is because gaps or misalignments may occur.

On the other hand, if the tightening is made too strong in order to prevent such a situation, there is a problem in that the comfort of use is reduced.

The present invention is proposed to solve these problems and is attached only to the glans using adhesive.

Hereinafter, an embodiment of the present invention will be explained according to the drawings.A semen reservoir 6 is integrally formed at the center of the tip, and is formed with sufficient thickness to cover only one glans and maintain a regular shape that fits the glans, and the outer periphery of the main body. The gist is that the main body 1 has cuts 8 formed toward the center of the main body at appropriate locations of 3, and the inside of the main body, leaving the inner peripheral part 2 adjacent to the semen reservoir 6, is covered with double-sided tape having a tab 5. do.

Although the semen reservoir 6 may have a conventional configuration, the main body 1 is preferably configured to maintain a regular shape that fits the glans in order to be easily attached to the surface of the glans.

For this purpose, it is preferable to form the main body 1 with a thickness sufficient to maintain a regular shape that fits the glans.

A thickness of about 0.2 to 0.477+71 would be sufficient.

In addition, the length of the semen reservoir is 2orIr! The main body 1 may have a height of about 10 mm, and the rounded surface may have a height of about 2-φ.

Adhesive 7 is applied to the inside of the main body, but in order to facilitate attachment to the surface of the glans and achieve as much comfort in use as possible, and to make it easier to peel off after use, it is applied leaving the inner periphery 2 of the main body intact. do.

The surface of the adhesive is covered with adhesive cover paper 4 so that the adhesive 7 only needs to be exposed during use, but this prevents the insides of the main body from adhering to each other during storage.

A part of the adhesive cover paper 4 is made to protrude to form a grip portion 5 so that the adhesive cover paper 4 can be easily peeled off during use.

The primary purpose of this adhesive 7 is to attach it to the surface of the glans when wearing a condom, but after use, if the inner sides of the main body are glued together, semen leakage from the semen reservoir 6 to the outside can be prevented and disposal can be facilitated. It also has the effect of being easy to perform.

It may be advantageous in terms of production if double-sided tape is used to apply the adhesive 7 and cover the adhesive cover paper 4.

However, it goes without saying that the means for attaching the adhesive 7 and the adhesive cover paper 4 to the main body 1 may be any arbitrary method in consideration of improving production efficiency.

The adhesive used in this invention must not only come in direct contact with the glans, but must not cause irritation to the area, and must also be carefully considered so as not to cause problems in peeling off after use. It has to be something.

The selection may be made by appropriately selecting from those used in medical adhesives for medical tapes and the like that have been developed so far.

When using a condom constructed in this way, as long as it is properly attached with adhesive, there is no risk of it forming a gap with the surface of the glans or coming off during normal use, regardless of the expansion or atrophy of the male genitals.

Furthermore, this fact, which does not cause inflammation of the glans, has been confirmed through experiments.

However, in order to ensure that the condom can be worn more appropriately by a wide range of people in consideration of individual differences in the size of the glans, cuts 8 are formed at appropriate locations on the outer periphery 3 of the main body toward the center of the main body, as shown in Fig. 3. .

As a result, the outer circumferential portion 3 of the main body can be freely widened and narrowed, making it possible to wear the device in accordance with individual differences.

As described above, according to the present invention, it is possible to provide a condom that has a high contraceptive effect, is easy to put on, is easy to dispose of after use, and is comfortable to use.

Claims (1)

[Scope of utility model registration request] A semen reservoir is integrally formed at the center of the tip, which is thick enough to cover only the glans and maintain a regular shape that fits the glans, and cuts are formed at appropriate locations on the outer periphery of the main body toward the center of the main body. A condom characterized in that the main body is covered with a double-sided tape having a tab on the inside of the main body, leaving the inner periphery of the main body adjacent to the semen reservoir.
