FIG. 5 is a diagram illustrating a state in which the tape 20 is wound up integrally with the condom body 10 from the state of FIG.
FIG. 6 is a diagram showing an example of a cross section of the ring 30 and a passage for guiding the tape 20.
FIG. 7 is a view for explaining a condom mounting method.
FIG. 8 is a diagram for explaining a state after the condom is mounted.
The condom shown in FIGS. 1 to 8 has a condom main body 10, three tapes 20, a ring 30 (tape guide part), and a lid part 40.

  As shown in FIG. 4, the condom body 10 is formed by forming a thin elastic material such as rubber in a cylindrical bag, and a semen reservoir is provided at the tip.

The tape 20 is a thin film processed into a band shape, and is wound up integrally with the condom body 10 from the edge of the penis insertion opening toward the tip in a state along the outer surface of the condom body 10 (FIG. 4) ( FIG. 5).
Since the tape 20 becomes unnecessary after the mounting is completed, it is desirable that the tape 20 has a length that is not excessive when the condom body 10 is lowered to the base of the penis.

  The lid portion 40 is disposed on the opposite side of the rolled-up condom body 10 from the penis insertion opening (FIGS. 1 and 2), and the end of the unwinding portion of the tape 20 is fixed. When the penis is inserted into the condom main body 10, the lid 40 comes into contact with the tip of the condom main body 10, and the air in the semen reservoir is removed.

  For example, as shown in FIG. 1, the lid portion 40 has three strip-like plate portions extending symmetrically in the radial direction from the center of the ring 30, and the end of the unwinding portion of the tape 20 is the end of each plate portion. It is fixed to the tip portion (FIG. 3).

  The lid 40 is larger than the inner diameter of the ring 30 and smaller than the outer diameter. When not in use, the three plate portions of the lid portion 40 abut against the ring 30 (FIG. 2). Even if an attempt is made to insert a penis from the side of the lid 40 at the time of attachment, the lid 40 does not advance by hitting the ring 30, so that erroneous insertion into the condom body 10 is prevented. Further, when removing the ring 30 that is no longer necessary after the condom body 10 is mounted, the ring 30 is caught by the lid 40, so that the ring 30 and the lid 40 can be removed simultaneously (FIG. 8).

  The lid 40 is formed using, for example, a material such as resin having moderate elasticity. At the time of mounting, the lid 40 comes into contact with the tip of the condom body 10 and is deformed (FIG. 7). When the condom body 10 is lowered to the vicinity of the base of the penis, the lid 40 returns to its original state by the elastic force, and the tape 10 is pulled away from the condom body 10 accordingly.

  The ring 30 has three passages for guiding the tape 20 (FIG. 3). The unwinding portion (FIG. 5) of the tape 20 coming out of the condom body 10 in the wound state is fixed to the lid portion 40 through the passage of the ring 30.

  For example, as shown in FIG. 6, the ring 30 has a round cross section and is formed with an L-shaped passage 31 for guiding the tape 20. One opening H 1 of the passage 31 opens in a direction perpendicular to the radial direction of the ring 20, and the other opening H 2 opens toward the center of the ring 20. By such an L-shaped passage 31, the tape 20 fixed to the lid portion 20 bends inside the ring 20 in the passage 31 and is guided to the edge of the condom body 20 (FIG. 2).

  Here, the usage method of the condom which has the structure mentioned above is demonstrated.

  In the unused state, the condom body 10 is housed in a packaging bag (not shown) in a flat state rolled up as shown in FIGS. 1 and 2, for example. The tip of the plate portion of the lid portion 20 is in contact with the ring 30, and the condom main body 10 is in close contact with the lid portion 40. At this time, since the semen reservoir at the tip of the condom main body 10 is in close contact with the lid portion 40, the air in the semen reservoir is almost removed.

  The user removes the flat condom as shown in FIGS. 1 and 2 from the package, holds the outer edge of the ring 30, puts the tip of the penis against the insertion opening of the condom body 10, and attaches the ring 30 to the penis 1. Move down towards the root. Then, the center of the lid 40 arranged on the side opposite to the penis insertion opening of the condom body 10 hits the tip of the penis 1 covered with the condom body 10 and the tip of the plate part of the lid 40 is pulled downward by the tape 20. It is done. Therefore, the lid 40 is deformed as shown in FIG. 7 (FIG. 7).

  When the user further lowers the ring 30, the lid 40 is pressed against the tip of the condom main body 10 and stops. Therefore, the ring 30 moves away from the lid 40, and the rolled up tape 20 is removed from the condom main body 10. It will be pulled out. By pulling out the tape 20 from the condom main body 20, the condom main body 10 is extended toward the end, and the condom main body 10 is covered by the penis 1 accordingly. When the condom body 10 is extended to the vicinity of the end of the tape 20, the lid 40 returns from the deformed state (FIG. 7) to the original state, and the tape 20 is pulled by the elastic force and separated from the condom body 10 (FIG. 8). The user removes the ring 30 and the lid 40 after the penis 1 is covered with the condom body 10.

As described above, according to the condom according to the present embodiment, the insertion opening of the condom main body 10 is achieved by lowering the ring 30 toward the root of the penis 1 by applying the tip of the penis 1 to the insertion opening of the condom main body 10. The lid 40 disposed on the opposite side of the main body 10 comes into contact with the tip of the condom main body 10 and stops, the tape 20 rolled up with the condom main body 10 is pulled out, and the condom main body 10 is covered with the penis 1. At this time, the lid 40 is pressed against the tip of the condom body 10, and the air in the semen reservoir is pushed out. Therefore, unlike the conventional condom, there is no need to pinch the semen reservoir with a finger, and the condom can be easily attached with one hand.
In the condom according to the present embodiment, the conventional troublesome work of applying the condom to the tip of the penis while taking care not to get air by pinching the semen reservoir with fingers is very easy to attach the condom. Become. For this reason, it is possible to increase the frequency of use of condoms among those who have conventionally avoided using condoms because they are troublesome to wear, and can contribute to the prevention of sexually transmitted diseases.
Further, since the condom according to the present embodiment can be easily mounted with one hand, there is an advantage that it can be easily used even by a person with a handicapped hand or a person who is not good at fine work.
In addition, since it can be mounted without touching the condom body 10 directly, it is possible to prevent the condom body 10 from being damaged by a nail or the like. is there. In general, a lubricant is applied to the surface of the condom, and when it comes into direct contact, the fingers become sticky due to the lubricant, but the condom according to this embodiment can be mounted without touching directly. There is also an advantage that it can be used comfortably without causing such problems.

  Moreover, according to the condom which concerns on this embodiment, since the cover part 40 is larger than the internal diameter of the ring 30, it can prevent inserting a penis accidentally from the opposite side of the insertion port of the condom main body 10. FIG. Moreover, when the ring 30 is removed from the penis after the condom body 10 is mounted, the lid 40 is hooked on the ring 30, so that the ring 30 and the lid 40 can be easily removed.

  Moreover, according to the condom which concerns on this embodiment, since the cover part 40 is smaller than the outer diameter of the ring 30, it becomes easy to grasp the outer edge of the ring 30 by hand, and mounting | wearing of a condom becomes easier.

  Further, according to the condom according to the present embodiment, one opening H1 of the passage 31 opens in a direction perpendicular to the radial direction of the ring 20, and the other opening H2 opens toward the center of the ring 20. Therefore, the gap between the lid 40 and the condom body 10 when not in use can be narrowed, and air can be prevented from entering the semen reservoir of the condom body 10.

  Further, according to the condom according to the present embodiment, the lid 40 having elasticity is deformed by hitting the tip of the condom body 10 and is pressed against the semen reservoir in a wide area (FIG. 7), so that air to the semen reservoir is obtained. Can be prevented more effectively. In addition, the lid 40 is deformed by hitting the tip of the condom main body 10 at the time of mounting, and the tape 20 is pulled and separated from the condom main body 10 by the elastic force of the deformed lid 40 returning to the original state. It can prevent that 20 remains in the state wound by the condom main body 10. FIG.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.
In the condom according to the first embodiment described above, only one end of the tape 20 is fixed to the lid 40, whereas in the condom according to the second embodiment, both ends of the tape 20 are lid 40. The tape 20 inserted in the passage of the ring 30 is not separated from the ring 30.

FIG. 9 is a diagram illustrating the ring 30, the tape 20, and the lid 40 in the condom according to the present embodiment. In the present embodiment, both ends of the tape 20 are fixed to the three plate portions in the lid portion 40. The tape 20 is bent in a V shape substantially at the center. One tape 20 is wound up integrally with the condom main body 10 in a state of being folded in two as shown in FIG. 9, for example.
In the state where the condom main body 10 is rolled up, two unwinding portions are generated per one tape 20, and one of the unwinding portions is fixed to the lid portion 40 through the passage of the ring 30, The unwinding portion is directly fixed to the lid portion 40. As a result, the tape 20 inserted into the passage of the ring 30 is not separated from the ring 30.

  According to the condom according to the present embodiment, since the tape 20 is not separated from the ring 30 after the condom main body 10 is mounted, the ring 30, the tape 20 and the lid 40 can be removed integrally. Moreover, since the ring 30, the tape 20, and the cover part 40 do not fall apart, they can be easily put away.

  As mentioned above, although several embodiment of this invention was described, this invention is not limited only to embodiment mentioned above, For example, the various variation as described below is included.

  In the above-described embodiment, an example in which the ring 30 has a circular cross section is given, but the present invention is not limited to this. That is, the cross section of the ring 30 may be an arbitrary shape such as an ellipse, a triangle, a sector, or a rectangle.

  Moreover, it is desirable for the cross section of the ring 30 to have a shape such that the gap between the condom main body 10 and the lid 40 becomes narrower. By narrowing this gap, it is possible to make it difficult for air to enter the semen reservoir at the tip of the condom body 10.

FIG. 10 is a diagram illustrating an example where the ring 30 has a triangular cross section.
In the example of FIG. 10, the slope corresponding to the side portion of the triangle is inclined toward the center of the ring 30, and the outer edge (the tip of the plate portion) of the lid portion 40 abuts on this slope. The gap between the lid 40 and the condom body 10 becomes narrower as the contact position between the lid 40 and the slope becomes lower (inside the ring 30).

  In addition, as shown in FIG. 10, when the inclined surface is provided in the inner edge of the ring 30, you may provide an inclined surface also in the outer edge of the cover part 40. As shown in FIG. By bringing the inner edge of the ring 30 and the outer edge of the lid portion 40 into contact with each other on the inclined surfaces, and the lid portion 40 is deeply recessed inside the ring 30, the gap between the lid portion 40 and the condom body 10 is further increased. It can be narrowed. Moreover, the positional deviation to radial direction can be suppressed effectively by making the ring 30 and the cover part 40 contact stably on a mutual slope.

  Further, if the apex portion of the cross section 30 is rounded, when the condom main body 10 and the ring 30 come into contact with each other, excessive pressure and frictional force are hardly generated at the contact portion.

As another embodiment of the present invention, for example, as shown in FIGS. 11 and 12, a groove that fits the lid portion 40 may be provided on the inner edge of the ring 30.
FIG. 11 shows an example of a plan view of the unused condom as seen from the opposite direction of the penis insertion opening, and FIG. 12 shows the unused condom shown in FIG. 11 cut along the chain line ABC. An example of a cross-section is shown.
As shown in FIG. 12, a groove 32 is provided on the inner edge of the ring 30, and the tip of the plate portion of the lid portion 40 is fitted into this groove 32. An opening of a passage for guiding the tape 20 is provided at the bottom of the groove 32. 11 and 12, the lid portion 40 can be deeply recessed inside the ring 30, and the gap between the lid portion 40 and the condom body 10 can be narrowed. Moreover, the position shift of the cover part 40 and the ring 30 can be suppressed more effectively.

In the above-described embodiment, the passage 31 of the ring 30 provided for guiding the tape 20 is closed except for the openings at both ends, but the present invention is not limited to this. That is, as another embodiment of the present invention, for example, as shown in FIG. 13, the passage 31 may be formed so as to have a slit S <b> 1 that opens toward the inside of the ring 30. Since the tape 20 can be taken in and out through the slit S1, for example, the tape 20 can be passed through the passage 31 even after the tape 20 is wound up integrally with the condom body 10 and fixed to the lid 40, thus simplifying the manufacturing process. Can be
In the example of FIG. 13, the slit is opened toward the inside of the ring 30, but the slit may be opened toward the outside of the ring 30.

Further, the position of the slit is arbitrary, and for example, it may be the central portion of the passage 31 as shown in FIG. 13 or the end portion of the passage 31 as shown in FIG. If the slit S1 is provided at the end portion of the passage 31, the belt-like tape 20 can be passed through the passage 31 without being bent or folded, so that the manufacturing process can be further simplified.
In this case, for all the passages 31 formed in the ring 30, the position of the slit S1 viewed from the center of the ring 30 may be unified to either the right end or the left end of the passage 31. By unifying the positions of the slits S1 for all the passages 31, the tape 30 can be passed through all the passages 31 so as to rotate the ring 30 in one direction, so that the manufacturing process can be further simplified.

In general, since condoms are used in the dark, it is desirable to be able to put them on without fail using only the hand feeling. In the condom according to the present embodiment, erroneous insertion is prevented by closing the opposite side of the insertion port of the condom main body 10 with the lid part 40, but it is expressed by further applying unevenness and coloring to the lid part 40. And the back (the penis insertion side and the opposite side) can be easily distinguished.
In other words, the front and back surfaces of the lid 40 are provided with irregularities on the surface opposite to the surface (inner surface) that comes into contact with the condom body 10 (outer surface) so that the surface can be touched with a finger. I can grasp. As a result, the front and the back can be easily identified even in a dark place, and it is easy for a blind person to use.
In addition to the lid portion 40, for example, irregularities may be provided on the front side of the ring 30 (the side in contact with the lid portion 40). In this case, the same effect as described above can be obtained.
Furthermore, if a region containing a fluorescent material is provided on the outer surface of the lid 40, the back and front can be easily distinguished from each other even in a dark place.

In another embodiment of the present invention, the lid 40 and the ring 30 may be separably bonded or fixed in an unused state.
For example, the contact portion between the lid portion 40 and the ring 30 may be bonded with an adhesive having a relatively weak adhesive force so that the bonded portion can be easily separated during use.
Alternatively, one or both of the lid 40 and the ring 30 are provided with claws, protrusions, etc., and one is fixed with the other sandwiched between them, and this fixing is made easy by the elasticity of the lid 40 (or the ring 30). It may be possible to remove it.
Thereby, it can prevent that the tape 20 will remove | deviate from the condom main body 10 by the cover part 40 moving away from the ring 30 in an unused state.

  In the example of FIG. 6, the passage 31 of the tape 20 is bent in an L shape. However, as shown in FIG.

  1 and 11, the lid 40 is smaller than the outer diameter of the ring 30, but the lid 40 may be larger than the outer diameter of the ring 30.

  In the above-described embodiment, three tapes 30 are provided, but this number is arbitrary and may be two or less or four or more.

  In the above-described embodiment, the tape guide portion has a ring shape (ring 30), but the present invention is not limited to this. That is, the shape of the tape guide portion may be arbitrary as long as it has a path for guiding the tape 20 and a hole for inserting the penis when mounted.
