[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condom which is a contraceptive device or a preventive hygiene device, and more particularly to a condom having an improved tightening function at the opening end.

[0002]

2. Description of the Related Art Conventionally, condoms have been used as a highly safe contraceptive device for a long time. However, the use of contraceptives for women such as pills has been slightly reduced in their usage.

[0003] However, it seems that the amount of condom is increasing again due to the review of condoms from the standpoint of epidemics and hygiene along with the signs of epidemics such as AIDS.

Conventional condoms have been devised in various ways from the viewpoint of safety and convenience in use.

For example, Japanese Utility Model Laid-Open No. 3-33618 discloses a condom in which the end portion of the mouth portion is thicker or thicker than the central portion (FIGS. 4 and 5). The purpose is stated that the mouth part does not strongly press the male base part in the radial direction at the time of use and the mouth part does not get inside the female part. Certainly, it is natural to make this improvement because there is a problem that it is not desirable in terms of blood circulation to strongly press the male base portion in the radial direction and the wearing feeling is not good.
However, the annular end could not be omitted in order to secure the winding property.

However, as far as the cross-sectional view of this embodiment of the prior art is seen, the inner diameter of the end portion 5A of the opening portion (mouth portion) is about 50% larger than that of the central portion, so that the tightening during use is On the contrary, there was a problem that the adhesion was insufficient and there was a high risk of liquid leakage or dropping. In this respect, it seems that the conventional example prior to the application of Kaikaihei 3-33618 was superior to the conventional one.

Further, it is necessary to prevent AIDS from the viewpoint of hygiene, and not only to avoid direct contact between amphoteric (including cases of same sex) organs with latex etc. Despite the need to attack both at the same time, no condom has yet been proposed that allows such an action.

Therefore, as a result of earnest studies, the inventor of the present invention has tried to ensure the tightening property, the pressure dispersion property and the winding property of the end portion of the opening.
The invention has been reached.

Further, the present inventors have reached the present invention as a result of their efforts to obtain a condom which is capable of automatically applying the active agent and is extremely effective in terms of epidemics and hygiene.

[0010]

The purpose of the present invention is an object of the invention] is not only to secure the winding resistance as well as distribute the local clamping pressure of the opening end, disease
It is to provide a condom that is effective in preventing airborne infection .

Another object of the present invention is that the active drug is automatically applied at the same time when it is unfolded at the time of use and mounted on the male genitalia, and the active drug is spread over the entire surface during use and is effectively AI.
It is to provide condoms that can prevent the transmission of diseases such as DS.

According to the present invention, in a condom having a semen reservoir at the tip and extending in a cylindrical shape, a porous hollow tubular elastic ring is used.
Sol activity that attacks the human immunodeficiency virus HIV
The sex drug is interpolated, and the drug
Is applied to the outer surface of the tubular portion, the end of the opening is
Provided is a condom, which is an end portion of an opening having a trapezoidal trapezoidal elastic annular portion for fastening with a cutout and a hollow tubular elastic annular portion for winding.

The present invention will be described in detail below with reference to embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view of the embodiment of the present invention when it is developed, FIG. 2 is a sectional view of the same embodiment when it is wound, FIG. 3 is an enlarged sectional view of the end of the opening, and FIG. FIG. 5 is a cross-sectional view of the conventional example when wound.

1, 2, 3 and 4, 1 is a condom, 2 is a tip portion, 3 is a cylindrical body portion, 4 is an opening portion, 5 is an opening portion end portion, and 10 is a trapezoidal elastic section for fastening. An annular portion, 15 is a notch, 20 is a hollow tubular elastic annular portion for winding, and 30 is a sol active agent.

1, 2 and 3, in the embodiment of the present invention, the opening end portion 5 is composed of a trapezoidal trapezoidal elastic annular portion 10 for fastening and a hollow tubular elastic annular portion 20 for winding. The tightening annular portion 10 has a trapezoidal shape having a plurality of notches 15. Further, the winding annular portion 20 is an airtight or porous hollow annular portion and may remain hollow (invention according to claim 1), or as a porous active agent in a sol state inside. The interior can be installed (the invention according to claim 2). Active agents include, for example, the human immunodeficiency virus HIV
Vaseline is supplemented with an inhibitor such as suramin sodium that attacks.

This active agent does not come into contact with air during winding (from production to use by the user), but it is developed during use, and when pressurized, it leaches out as shown in FIG. Is even applied to the tip of. In addition to the above, the drug to be incorporated may be a simple lubricant, a spermicidal agent, or the like.

[0018]

By implementing the present invention, all of the above objects can be achieved.

That is, the condom of the present invention has elastic for tightening.
The annular part has a trapezoidal cross section, and the outer peripheral direction is perpendicular to the longitudinal direction.
Since it has a plurality of grooves (notches), it can disperse the local tightening pressure at the end of the opening, secure the winding property , and form a sol.
We can provide condoms suitable for holding and spreading medicines .

Further, the active drug is automatically applied at the time of use, and a condom which can effectively prevent the transmission of diseases such as AIDS can be obtained.
