Description

Ejaculation promotion device

The present invention relates to an ejaculation promoting device, and has been used conventionally based on social requests such as medical research, treatment requests, prevention of sex crime, prevention of prostitution, and spread of sexually transmitted diseases. The present invention relates to an improvement of an ejaculation promoting device.

Various sperm collection devices (ejaculation promotion devices) for collecting male sperm have been proposed for medical research and treatment needs. For example, medical needs such as examining husband's sexual function from sperm collected to investigate the cause of infertility between couples, treating sexual dysfunction, securing sperm for artificial insemination, etc. A sperm collection device is used for this purpose. Furthermore, in order to satisfy various social needs such as prevention of sex crimes by eliminating personal sexual desires, prevention of prostitution, and reduction in the number of persons infected with sexually transmitted diseases, they must be obtained at low cost. In addition, a simple sperm collection device that does not cause any health and health problems because it is a disposable type is known.
In recent years, attention has been focused on the need for sexual desire processing not only for healthy individuals but also for elderly and disabled people in various nursing and nursing care facilities. Development is required.
For example, in Utility Model Registration No. 3076627 (Patent Document 1), an interior material (core member) made of a gel-like synthetic resin (styrene-based thermoplastic elastomer) having a deep recessed space inside a cylindrical container body. Sperm collection with a plurality of small protrusions projecting into the recess space and a hook-shaped portion inside the interior material, and an exterior material made of urethane resin in a state of covering the periphery of the interior material A vessel has been proposed.
This sperm extractor inserts an assembly body in which an exterior material is assembled so as to cover the periphery of the interior material into the interior of the container from an opening provided at one end of a cylindrical container body, and then the container opening is covered with a cap. It is sealed. In use, the sperm is collected by removing the cap and holding the container body in a state where the penis is inserted into the recessed space of the interior material housed in the container body and performing a reciprocating operation for rubbing the penis.

However, this type of sperm collection device has a structure in which a bag-like interior material is fixed inside the container body and only the interior material cannot be taken out. It is not suitable for repeated use and is basically a disposable type. For this reason, there were difficulties in terms of economy and environmental load. Further, even if the recessed space of the interior material housed in the container body is forcibly cleaned, it is difficult to clean every corner, so repeated use is unsanitary. In addition, because the interior material is completely stored in the rigid container body, the exterior surface of the interior material cannot be touched by hand during rubbing, and the strength of the pressure applied to the penis and the pressure location are manually adjusted Is impossible to do. Further, when an interior material having a bag-like configuration is manufactured by injection molding, it is difficult to form a complicated shape (projection, ridge, etc.) inside the interior material in consideration of die cutting and the like.
On the other hand, unless the interior material is accommodated in the container body made of a hard resin, it is impossible to apply a sufficient tightening force to the penis. Therefore, a configuration in which the interior material is accommodated by the container body is necessary.
In Patent Documents 2 to 4, the present applicant accommodates a gel-like resin core member in the container body, and adhesively fixes the outer periphery of the sponge lid attached to the distal end surface of the core member to the inner wall of the container body. A sperm collection device (ejaculation promoting device) was proposed in which the core member was positioned in the container body.
However, these sperm collection devices have the same problems as in Patent Document 1.

Utility model registration No. 3076627 JP 2006-334176 A JP 2006-340870 A JP 2006-340871 A

As described above, the conventional sperm collection device is basically a disposable type because it has a configuration in which a core member made of a soft resin is fixedly accommodated in a container made of a hard resin, and cannot be repeatedly used. Therefore, there were problems in terms of economy and environmental load. Moreover, since the outer surface of the core member cannot be touched during use, there is a problem in usability that stimulation to the penis cannot be controlled.
The present invention has been made in view of the above, and while maintaining the merit of housing the core member in the container, the core member can be easily washed without causing sanitary problems. An object of the present invention is to provide an ejaculation promoting device that can be used and can arbitrarily control a stimulus applied to a core member during a rubbing operation.

The elastic porous member confined between the core piece and the case piece functions as an air cushion, and can apply a moderate pressure and stimulation to the penis reciprocating in the insertion space to enhance the sperm collection effect it can. In addition, since the elastic porous member is lighter than the resin material that constitutes the core piece, the ejaculation promoting device can be reduced in weight to improve operability and handling, and the resin constituting the core piece can be improved. Compared with the low price, the cost can be reduced.
According to a second aspect of the present invention, each case piece is a substantially semi-cylindrical body made of a hard resin plate, and the elastic porous member has an outer surface fixed to an inner recess inner wall of each case piece and a width of the inner surface. And the core piece has a configuration in which the thinnest thickness of a portion corresponding to the center surface in the width direction of the elastic porous member is the width direction of the elastic porous member. It is characterized by being set thinner than the thickness of the part corresponding to both ends.

In the invention of claim 3, each core piece hermetically seals each elastic porous member between the inner surface of each case piece, and is disposed in a through hole formed in each case piece. The venting mechanism enables the air in each of the elastic porous members to communicate with the outside air or to block the communication.
According to a fourth aspect of the present invention, the venting mechanism includes a through-hole formed in at least one of the case pieces, a large-diameter flange portion, and a hollow shaft projecting integrally from the center portion of the flange portion. A valve member that includes a member and is supported by the through-hole so that the shaft member can be protruded and retracted inward and outward with the outer surface of the flange portion exposed to the outside, and an elastic member that constantly urges the valve member outward. A cap member made of an elastic material and covering the outer surface of the flange portion, and the hollow portion of the shaft member has an inner opening on the side surface in front of the closed tip portion, and the flange of the hollow portion The part side communicates with a cavity formed in the flange part, the cavity part in the flange part communicates with an outer opening provided in the flange part, and the valve member is positioned outward by urging of the elastic member. Shi While the inner opening is closed by the packing provided in the through hole when the valve member is pushed in against the urging force of the elastic member, the inner opening is opened and the A hollow portion communicates with the elastic porous member, and the cap member is continuously integrated with the pressed surface covering the upper surface of the flange portion, and the outer opening of the flange portion is elastically integrated. An opening / closing piece that opens and closes, and the opening / closing piece of the cap member normally closes the outer opening while elastically deforming when the pressed surface is pushed into the inside, and the outer opening. It is characterized by opening.
According to a fifth aspect of the present invention, the through hole includes a flange portion accommodating portion that is a large-diameter recess for accommodating the flange portion of the valve member and the cap member, and the shaft member extends inward from the flange portion accommodating portion. A small-diameter tubular shaft member guide portion that guides the axial movement of the cap member, and the cap member that covers the valve member when the valve member is in the outermost position in the axial direction by the biasing of the elastic member; A waterproof structure for preventing water from entering between the flange housing portion and the flange housing portion is provided.

According to a sixth aspect of the present invention, the waterproof structure is provided in a ring shape from a skirt-like elastic airtight piece projecting inward from the entire outer periphery of the cap member and an inner bottom surface of the flange portion accommodating portion. A waterproof annular wall that is in airtight pressure contact with the elastic airtight piece, and the waterproof airtight piece is rolled up in an outer radial direction when the pressed surface of the cap member is pushed inward. A ventilation path is formed between the two.
According to a seventh aspect of the present invention, ribs that contact the inner wall of the flange housing portion are provided on the outer circumferential surface of the elastic airtight piece in an arbitrary arrangement in the circumferential direction, and a gap formed between the ribs is provided as a ventilation path. It is characterized by that.
In the invention of claim 8, ribs that contact the inner wall of the flange housing portion are provided in an arbitrary arrangement in the circumferential direction on the outer surface of the opening / closing piece, and a gap formed between the ribs serves as a ventilation path. It is characterized by that.

According to the present invention, the core member is not composed of the bag body, but is composed of the two core pieces constituting the bag-like core member by being assembled.

Moreover, since the core member is a non-bag-shaped body and the recess is exposed when opened, a mold having a simple structure can be used when the core piece is manufactured by injection molding. Therefore, it becomes easy to give variations to the inner surface shape of the core piece, such as forming complicated protrusions, wrinkles, etc., and it is possible to enhance the feeling of use.
In addition, the elastic porous member enclosed between the core piece and the case piece functions as an air cushion, and gives an appropriate pressure and stimulation to the penis reciprocating in the insertion space to enhance the sperm collection effect. be able to. In addition, since the elastic porous member is lighter than the resin material that constitutes the core piece, the ejaculation promoting device can be reduced in weight to improve operability and handling, and the resin constituting the core piece can be improved. Compared with the low price, the cost can be reduced.

Although the ejaculation promoting apparatus according to the present invention is certainly used as a means for resolving personal libido other than for medical purposes, ejaculation that may be used for such purposes. It is premature and prejudiced to conclude that it is a product that disturbs public order and morals just because it is a facilitating device. Please judge whether it is worth granting patent rights from a broad perspective of how this type of product will help prevent sexual crimes and spread of sexually transmitted diseases.
Incidentally, the following cases are based on facts, and there is no doubt that ejaculation promotion devices are useful as a means of meeting these social demands. As a matter of course, the ejaculation promoting device itself according to the present invention is in an undisclosed and unknown state.
First, this application was published in the paper “Rehabilitation using Masturbator for patients with ejaculation disorders” published by Dokkyo Medical University Koshigaya Hospital, Department of Urology, published in Japanese Journal of Sexual Function Vol. 24, No. 3, December 2009 It is described that a sperm collection device (ejaculation promotion device) manufactured and sold by a person is effective in carrying out proper masturbation.

To investigate whether or not The center is currently preparing for the survey.
In special nursing homes for the elderly, measures to eliminate the sexual desire of the elderly are required. In other words, the importance of the “sex” part for QOL (quality of life) of the elderly is as pointed out recently, and 80% of the troubles that occur in these facilities are gender problems, in other words, color love. It is said that they are closely related. The sperm collection device that the applicant has manufactured and sold in the past has been helping elderly men enjoy “sex”, and by providing “living” and “joy and pleasure to live”, it can improve QOL. It is clear that they are contributing.
Also, until now it has not been said for a long time about the “sex” of disabled people. Japanese society has continued to cover the “sexual desire”, which should be one of the fundamental needs of human beings, without disabilities. The applicant has continued to approach the sexuality of persons with disabilities as part of realizing the philosophy of creating a society where everyone can enjoy sexuality. Offering products to parents with children with disabilities and consulting about masturbation guidance for children with autism from secondary school teachers.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
1 (a) and 1 (b) are perspective views showing an assembled state of the ejaculation promoting apparatus according to one embodiment of the present invention, respectively, and FIGS. 2 (a) and 2 (b) show an openable opening / closing unit and holder. FIG. 3 is a perspective view showing the closed opening / closing unit and the holder, FIG. 3 is an exploded perspective view showing the configuration of the opening / closing unit, and FIGS. 4A to 4E show the assembled state of the opening / closing unit. It is a front view, a top view, a left side view, a right side view, and a bottom view, and FIGS. 5A and 5B are a cross-sectional view of the ejaculation promoting device and a cross-sectional view of the opened ejaculation promoting device. is there.
The ejaculation promotion apparatus 1 is generally configured by an opening / closing unit 2 and a holder 30. The opening / closing unit 2 includes two case pieces 4 that are supported so as to be openable and closable around a hinge portion 3 provided at a side edge, an elastic porous member 10 disposed on the inner surface of each case piece 4, and each case A non-breathable core piece 20 disposed along the inner surface of each elastic porous member so as to hermetically seal each elastic porous member 10 between the inner surface of the piece 4 and fixed to each case piece; And an air bleed mechanism 40 disposed in the through hole 6 provided in each case piece 4 for communicating the air in the elastic porous member 10 with the outside air.
The two case pieces 4 constitute a case. The hinge portion 3 is made of, for example, a flexible resin sheet. The resin sheet is used as a hinge by bonding and fixing the resin sheet to the edges of both case pieces.

Each core piece 20 is supported on the inner surface of each case piece 4 via an elastic porous member 10 and opens and closes together with each case piece. When the case piece is closed as shown in FIG. An insertion space 21 for penis insertion is formed between them.
The holder 30 holds the open / close unit 2 in a closed state in a detachable manner in a usable state as shown in FIG. In addition, in the use state shown in FIG. 1, since the insertion opening 21a for penis insertion is exposed, the ejaculation promotion device is in a usable state. On the contrary, the insertion opening 21a for penis insertion is provided. When the holder is mounted so as to be closed at the base 31 of the holder, it becomes unusable.
Each case piece 4 is made of a relatively hard resin plate, and when closed as shown in FIG. 1, a recess is formed inside each case piece 4 so as to form a cylindrical hollow portion 5 shown in FIG. 5a is formed. In each recess 5a, an elastic porous member 10 is interposed, and the core piece 20 is fitted and accommodated in an aligned state and fixed. Since the cylindrical hollow portion 5 is formed when the case piece is closed, a pair of core pieces (core member) made of a soft material is accommodated in the cylindrical hollow portion to maintain the shape, and deformation during use, deformation, and buckling Can be prevented.
The two case pieces 4 form a container.

The hinge portion 3 may be configured as a connecting piece integrally formed when the case pieces 4 are formed, or may be retrofitted. Moreover, in this example, although the site | part along one long side of each case piece 4 is used as the hinge part 3, the site | part along the short side is good also as a hinge part.
The elastic porous member 10 is composed of a soft material such as urethane foam (sponge) having a large number of fine holes communicating with each other, and is inflated by its own elasticity when not pressurized. The air is held in the hole by maintaining the pressure, and the air in the hole is discharged in a state compressed by pressurization. As shown in the sectional view of FIG. 5, the elastic porous member 10 is fixed in a state where the outer surface is in close contact with the inner wall of each case piece 4, and the inner surface is in close contact with the core piece 20.

As shown in the sectional view of FIG. 7A, each case piece 4 is a substantially semi-cylindrical body made of a hard resin plate, and the elastic porous member 10 has its outer surface fixed to the inner recess inner wall of each case piece. In addition, the central surface in the width direction of the inner surface of the elastic porous member 10 is bulged from both ends in the width direction. As a result of the center surface in the width direction of the elastic porous member 10 bulging inward, this bulging part is more easily deformed by compression than other parts, and more easily swelled by decompression, so that the insertion space When the penis is inserted into the place 21, the pressure applied from the core piece pair (core member) and deformation due to the pressure release are facilitated.
In the core piece 20 according to this example, the thickness of the portion corresponding to the center surface (bulged portion) in the width direction of the elastic porous member 10 is larger than the thickness of the portions corresponding to both end portions in the width direction of the elastic porous member. Is also set thin. For this reason, the force that presses the central portion in the width direction of the core piece 20 generated by the expansion of the elastic porous member 10 in the inner diameter direction is faithfully reflected on the core piece side, so that the thin portion of the core piece is on the inner diameter side. It can be deformed to enhance the ejaculation promoting effect.

Next, the structure in which the core piece 20 is integrated with the case piece 4 via the elastic porous member 10 is a state in which the elastic porous member 10 is positioned inside the case piece, and the case piece is placed in the molding cavity of the mold. It can be manufactured by performing injection molding in which the resin material constituting the core piece is injected into the molding cavity.
At least a part of the core piece 20 is made of a soft resin such as a gel resin, and the contact surface between the case piece 4 and the core piece 20 is integrally fixed at the time of injection molding. The core piece 20 of the present embodiment has a configuration in which the entire inner surface of the elastic porous member 10 is covered with a soft resin layer 23 as shown in the cross-sectional view of FIG. The recess 24 is formed. A recess 26 serving as an insertion port 21a is formed at one end of the recess 24 in the axial direction. An insertion opening 4a is formed on the end surface of the case piece 4 corresponding to the insertion opening 21a. The opening 4a may have a shape that exposes the entire insertion port 21a. Alternatively, the insertion port 21a may be normally closed with a soft resin that forms the peripheral edge of the insertion port, and the insertion opening 4a may be closed with a soft resin that forms the insertion port 21a.
Further, the insertion side end of the case piece 4 is cut by a predetermined length to shorten the length, and the insertion side end of the core piece (arc-shaped portion having the insertion port 21a) is always exposed (protruded) to the outside of the case piece. You may comprise as follows.

The soft resin constituting the core piece 20 is made of a gel-like resin having elasticity such as an elastomer, or a gel-like rubber. Unlike the conventional core member, the core piece 20 is not shaped like a bag, but is shaped like a bag divided into two in the axial direction, so that the mold used for injection molding can be simplified. Accordingly, protrusions, ridges and the like are formed on the inner wall of the recess 24 in any arrangement and shape. The two core pieces 20 constitute a core member 20A.
The core piece 20 made of a non-porous material has a higher density than the urethane foam or the like that constitutes the elastic porous member 10, and there is no room for taking in the gas therein.
The elastic porous member 10 enclosed between the core piece 20 and the case piece 4 made of such a material functions as an air cushion, and has an appropriate pressure against the penis reciprocating in the insertion space 21. Stimulation can be given to enhance the sperm collection effect.
In addition, since the elastic porous member 10 is lighter than the gel-like resin material constituting the core piece, the ejaculation promoting device can be reduced in weight to improve operability and handleability. Compared with the low price, the cost can be reduced.

As shown in FIG. 2 and the like, the holder 30 attaches and detaches the base 31 having a flat bottom surface 31a provided at one end in the axial direction and the opening / closing unit 2 that extends in the axial direction from one location of the base 31 and is in a closed state. And a holding portion 35 that guides and holds the opening / closing unit so as not to drop off.
A protrusion 7a having a dovetail groove portion 7b is formed on the edge 7 of each case piece 4 on the opposite side to the hinge portion 3, as shown in FIGS. 1 (b) and 5 (a). When the pieces are closed, the ridges 7a come close to each other to form a ridge 7A having a substantially trapezoidal cross section. In this case, the protrusion 7a may be provided only at a required portion of the edge 7 or may be a long protrusion extending over the entire length in the longitudinal direction of the edge 7 or a part thereof.
1 and 5 (a) are explanatory views showing a state in which the holder is assembled to the opening / closing unit. A guide groove 36 is formed on the inner side surface of the holder holding portion 35 to receive the projection 7A and guide the axial movement. Since the guide groove 36 has a shape that can receive the trapezoidal protrusion 7A in cross-sectional shape, the guide groove 36 can receive the protrusion 7A from the one end opening in the axial direction of the guide groove 36 or from the other end portion in the axial direction. Can guide. Since the projection 7A composed of the two protrusions 7a is guided while being pressed so as not to separate the guide groove 36, the case piece 4 can be held by the holder 30 without being separated.

In the usable state shown in FIG. 1B, when the penis is not inserted into the insertion space 21 from the insertion port 21a in the closed state, the insertion space 21 becomes a sealed space. Yes.
The opening / closing unit 2 can be opened in the order shown in FIGS. 2 (a) and 5 (b) from the closed state shown in FIGS. 1, 2 (b), and 5 (a). Since the inner surface of each core piece is exposed in the open state, the inside of the recess 24 can be cleaned to every corner. After the cleaning, the opening / closing unit 2 can be dried in an opened state.
After drying, the opening / closing unit 2 can be closed and attached to the holder, and the holder 30 can be covered and stored so that the base 31 of the holder closes the insertion port 21a, or can be used as shown in FIG. In use, a lotion is injected from the insertion port 21a. Alternatively, a lotion may be applied in the recess 24 of each core piece before closing the opening / closing unit 2.

Next, FIGS. 6A and 6B are exploded perspective views of the components constituting the venting mechanism, and FIGS. 7A and 7B are partial cross sections of the ejaculation promoting device including the venting mechanism. FIG. 8 is a perspective sectional view of the venting mechanism, FIG. 8 is a perspective view showing a procedure for mounting the valve member inside the cap member, and FIGS. 9A and 9B are venting by the venting mechanism. It is sectional drawing for demonstrating operation | movement, FIG. 10: is a bottom part perspective view which shows the structure of an example of a cap member.
In the present embodiment, the example in which the venting mechanism 40 is provided in each case piece is shown, but it may be provided only in one of the case pieces.
The venting mechanism 40 includes a through-hole member 42 including a through-hole 41 formed in each case piece 4, a valve member 50 supported in the through-hole 41 so as to be able to advance and retract in the axial direction, and the valve member 50 in the outward direction. An elastic member 60 that constantly urges the cap, a cap member 70, and an O-ring (packing) that is fixed to the inner wall of the through hole 41 by a washer 81 and seals the gap between the inner wall of the through hole and the shaft member 55 of the valve member. ) 80A and 80B. The valve member 50 and the cap member 70 constitute a button B.
A valve member 50 made of a metal or a hard resin includes a large-diameter flange portion 51 and a hollow shaft member 55 that protrudes integrally from the center portion of the flange portion, and the flange portion is connected to each case piece. The shaft member 55 is supported by the through hole 41 so as to be able to protrude and retract in the inner and outer directions.

A small-diameter tubular shaft member guide portion 44 that guides the axial movement of the shaft member.
The elastic member 60 is disposed between the washer 81 in contact with the outer O-ring 80B and the lower surface of the flange portion 51, and constantly biases the flange portion outward in the axial direction, thereby attaching the entire valve member in the same direction. To force.
The hollow portion 55a inside the shaft member 55 of the valve member 50 has an inner opening portion 55b on the side surface in front of the front end opening portion (inner end surface) 55c closed by the screw 56, and the flange portion side of the hollow portion 55a. Is communicated with a cavity portion 51a formed in the flange portion, and the cavity portion 51a in the flange portion 51 is communicated with an outer opening 51b provided on the lower surface and the outer peripheral surface of the flange portion, respectively. In short, the inner opening 55b communicates with the outer opening 51b via the hollow 55a and the cavity 51a. Each outer opening 51 b is normally closed by a part of the cap member 70.
A tip opening 55 c having a female screw part on the inner surface is provided at the tip of the shaft member 55, and this tip opening is closed by a screw 56. Therefore, the tip opening 55c is always airtightly closed.

As shown in FIG. 9A, when the valve member 50 is positioned outward in the axial direction by the biasing of the elastic member 60, the inner opening 55b is closed by the O-ring 80A disposed in the through hole 41. The hollow portion 55a is not in communication with the space S in which the elastic porous member 10 is accommodated. On the other hand, when the valve member 50 is pushed inward in the axial direction against the urging force of the elastic member 60 as shown in FIG. 9B, the O-ring 80A protrudes inward from the tip opening of the through hole member 42. The inner opening 55b is opened, and the hollow portion 55a communicates with the space in which the elastic porous member 10 is accommodated.

While 55b is prevented from communicating with the void S, the shaft member is displaced inward in the axial direction when the button B shown in FIG. The front end opening of 42 is opened to allow the inner opening 55b and the space S to communicate with each other.
In the axially outer O-ring 80B, the inner opening 55b communicates with the outside air through the space between the cap member 70 and the flange accommodating portion 43 when the button B is not pushed in as shown in FIG. To prevent you from doing.

The step portion 55 d provided on the outer periphery of the shaft member 55 is a stopper that prevents the valve member 50 from being excessively pressed by contacting the upper washer 81.
The cap member 70 is made of a thin elastic material such as resin or rubber, and covers the outer surface of the flange portion 51 of the valve member. That is, the cap member 70 includes an outer surface 71 covering the upper surface of the flange portion 51, an opening / closing piece 72 that is continuously integrated with the outer surface 71 and elastically opens and closes the outer opening 51 b on the lower surface of the flange portion, and an outer peripheral edge of the outer surface 71. And an elastic airtight piece 73 projecting downward in a skirt shape. In this example, the cap member 70 includes an accommodation space 70a for supporting the flange portion 51 in a press-fit state therein, and the cap member is detachable from the flange portion (FIG. 8). Moreover, the opening / closing piece 72 moves from the closed position (FIG. 9A) where the outer opening 51b is closed in the outer diameter direction (opening direction) along the flange lower surface to open the outer opening 51b ( It can be displaced up to FIG.

The elastic airtight piece 73 is hermetically sealed in a space between the flange portion accommodating portion 43 and the bottom surface of the cap member 70 by being pressed against a waterproof annular wall 43a projecting annularly from the bottom surface of the flange portion accommodating portion 43. ing. The elastic airtight piece 73 and the waterproof annular wall 43a constitute a waterproof structure.
The outer surface 71 includes a projecting pressed surface (pressed portion) 71a located at the center, and a projecting surface (projecting portion) 71b extending concentrically on the outer periphery of the pressed surface 71a. The flange portion 51 is tightly accommodated in the accommodation space 70a located inside the pressed surface 71a, and there is no flange portion on the inner side of the overhanging surface 71b. For this reason, when the pressed surface 71a is pushed inward and the valve member 50 is moved to the inner depth, the overhanging surface 71b is not pushed inside as a whole, and the inner diameter portion of the overhanging surface 71b that contacts the pressed surface 71a. Deforms to the inside. At this time, the outer diameter portion of the overhanging surface 71b rises relatively upward, and as a result, the opening / closing piece 72 continuously formed with the outer diameter portion of the overhanging surface 71b is pulled to the outer diameter side to open the outer opening 51b. Open. At this time, the elastic airtight piece 73 also rises relatively upward, so that it is separated from the waterproof annular wall 43a of the flange portion accommodating portion 43 to enhance air circulation between the outer opening 51b and the outside air.

That is, the opening / closing piece 72 of the cap member 70 is in close contact with the lower surface of the flange portion 51 when the pressed surface 71a is not pushed inward and closes the outer opening 51b, while being pressed by the operator. When the flange portion 51 of the valve member is pushed into the surface through the surface, the outer opening portion 51b is opened by elastically deforming in conjunction with the rising of the protruding surface 71b.
Further, when the pressed surface 71a is pushed inward in the axial direction by the operator's finger in a state where the cap member 70 is placed on the outer surface of the flange portion 51, the valve member 50 moves inward in the through hole member 42 as a whole. To do. At this time, the overhanging surface 71b of the cap member 70 is relatively swung upward, and the elastic airtight piece 73 is also swung upward with the overhanging surface, so that the space between the elastic airtight piece and the inner wall of the flange accommodating portion 43 is between. A gap for ventilation is formed. For this reason, the space S communicates with the outside air through the hollow portion 55a of the valve member. In a state where the pressed surface 71 a is not pushed in, the elastic airtight piece 73 is in close contact with the waterproof annular wall 43 a of the flange housing portion 43 and prevents rainwater from entering the through hole 41.

As described above, when the valve member 50 is not pushed into the inside, the inner opening 55 b does not communicate with the space S in which the elastic porous member 10 is accommodated, and the outer opening 51 b is also formed by the opening / closing piece 72. It is closed. For this reason, the elastic porous member 10 is in a state of being blocked from the outside air. Further, since the elastic airtight piece 73 is in intimate contact with the waterproof annular wall 43a of the flange accommodating portion 43 over the entire circumference, the rainwater is prevented from entering the inner diameter side of the intimate portion. Even if the outer opening 51b and the inner opening 55b are opened by this, rainwater can be prevented from entering the void S through the hollow 55a.

Next, in a state where the penis is not inserted into the insertion space 21 from the insertion port 21a in the use state shown in FIG. Once the force to push the valve member is released after being in communication with the outside air, the elastic porous member 10 is in a state where the air is filled in the pores.
In this state, since the space S between the case piece 4 and the core piece 20 is filled with air and the internal pressure is increased, the inner wall of the core piece constituting the insertion space 21 is pressurized and narrowed inward. ing.
For this reason, it is not easy to insert the penis from the insertion port 21a in this state, and it is difficult to insert the penis unless the pressure in the space is reduced.

On the other hand, when the pressed surface 71a of the cap member 70 is pushed to the inner back, the inner opening 55b communicates with the void S, while the opening / closing piece 72 is rolled to open the outer opening 51b. Communicate with the outside air. When the penis in the insertion space 21 is inserted in this state, smooth insertion is possible.
In order to promote ejaculation, when the present ejaculation promoting device is reciprocated with the penis inserted into the insertion space 21, the state in which the button B is pushed in is maintained. Alternatively, the reciprocation operation by the ejaculation promoting device may be performed while the push of the button B is stopped and the internal pressure is kept constant at the stage where the air pressure in the space S is set to an optimum state according to preference. In short, when the penis is inserted, the button B is pressed once to reduce the internal pressure in the space S, thereby facilitating the insertion of the penis into the insertion space, while pressing the button at any time after completing the insertion. It is possible to adjust the internal pressure by releasing or pressing.
When pressing the button B is stopped, the inner wall of each core piece comes into close contact with the outer surface of the penis, so that a feeling of adsorption can be obtained, and ejaculation is further promoted by the rubbing operation in this state. can do.
In short, when the button B is pushed in, the air in the void S is released from the through hole to the outside, so when the penis is inserted into the insertion void 21, the insertion void 21 of the core member is expanded and the penis is removed. When retracted, the insertion space is narrowed by the original restoring force of each core piece and the elastic porous member. Therefore, the state in which the penis and the inner wall of the insertion space are always in close contact with each other can be maintained, and ejaculation can be promoted by this close contact effect.

On the other hand, when the force for pushing the button B is released with the penis positioned in the insertion space, the air in the space S is not released to the outside. At this time, the penis is held by the insertion space, and when the penis is slid in the pulling direction in this state, a negative pressure space is formed inside the insertion space (the back side from the tip of the penis). Adsorption effect occurs.
That is, when the button B is pressed, the penis and the inner wall of the insertion space are in close contact with each other, and when the button is released with the penis inserted, the inner wall of the insertion space is adsorbed to the penis. In addition, if the timing of releasing the button is changed depending on the position (depth) inside the insertion space of the penis, the feeling of tightening and the adsorption effect will be different. For example, when the penis insertion depth is about 1/2, if you release the button to cut off the communication with the outside air, the amount of air remaining inside the void will be large, so the tightening force will be strong when the penis is inserted deep inside Become. Further, when the penis is pulled out from this state (because it is pulled out in a state where the tightening / adhesion is strong), a strong adsorption effect can be obtained.
Such a change in the feeling of close contact and feeling of use can be obtained only by changing the volume of the elastic porous member by the cooperation of the operations of button pressing, pressing release and penis insertion.
Next, in the case where the venting mechanism 40 is provided, in order to avoid the intrusion of foreign matters, particularly liquids such as water, from the outside into the void S that accommodates the elastic porous member 10 via the through hole 41. The need to provide a waterproof structure increases. Since the elastic porous member 10 has a water absorption property, when moisture is absorbed, the volume expansion during ventilation and the volume reduction during evacuation may not be performed smoothly. In addition, the hygienic condition in the empty space may be deteriorated due to water absorption.

7 and 9 show a waterproof structure 90 in the ejaculation promoting apparatus of the present invention.
When the valve member 50 is at the outermost position in the axial direction by the urging of the elastic member 60, the waterproof structure 90 is inserted into the through hole 41 from between the cap member 70 that covers the valve member and the flange portion accommodating portion 43. It is a means to prevent water from entering.
The waterproof structure 90 has an elastic airtight piece 73 projecting in a skirt shape from the entire circumference of the outer peripheral edge (projecting surface) 71b of the cap member to the inside, and an annular shape projecting from the inner bottom surface of the flange portion accommodating portion 43. A waterproof annular wall (inner wall of the flange portion accommodating portion) 43a that is in airtight contact with the piece 73. And when the to-be-pressed surface 71a of the cap member 70 is pushed inward, the elastic airtight piece 73 is rolled up in the outer diameter direction, thereby forming a ventilation path with the waterproof annular wall 43a.
Further, as shown by a broken line in FIG. 9, a part of the waterproof annular wall 43a is shortened (notched in a concave shape), whereby a ventilation path is formed between the elastic airtight piece 73 and the airtight piece 73 shown in FIG. Is configured to be easy to form.

Next, FIG. 10 is a bottom perspective sectional view of a cap member according to another embodiment, which will be described in comparison with the cap member according to the embodiment shown in FIG.
The cap member 70 according to the embodiment shown in FIG. 10 is different from the cap member shown in FIG. 8 in that the radially outer rib 75 projecting at a predetermined pitch along the outer periphery of the elastic airtight piece 73 and the opening / closing piece. The inner surface side ribs 76 project from the lower surface of 72 at a predetermined pitch in the circumferential direction.
The outer diameter side rib 75 is in contact with the inner wall 43b of the flange portion accommodating portion 43 on the outer surface thereof, thereby forming a constant ventilation path between the inner wall 43b and the elastic airtight piece 73. Therefore, not only when the button of FIG. 11A is not pressed but also when the button of FIG. 11B is pressed, a ventilation path can be formed between the inner wall 43b and the elastic airtight piece 73. It is possible to reliably discharge the air in the empty space S moving through the space to the outside.
When the outer diameter side rib is not provided as shown in FIG. 8, the elastic airtight piece 73 that elastically deforms toward the outer diameter side when the button B is pushed in contact with the inner wall 43b as shown in FIG. 9B. There is a possibility that the air in the void S may be prevented from flowing out.

On the other hand, when the outer diameter side rib 75 is provided, even if the elastic airtight piece 73 is deformed to the outer diameter side, a ventilation path is always secured between the outer diameter side rib and the inner wall 43b. Become.
When the button B shown in FIG. 11A is not pressed, the inner diameter side rib 76 is not in contact with the bottom surface of the flange accommodating portion 43, but the button B is pushed in as shown in FIG. At that time, the air in the void S is surely discharged to the outside through the space between the inner diameter side ribs 76 by contacting the bottom surface of the flange portion accommodating portion 43. If the inner diameter side rib 76 is not provided, the opening / closing piece 72 may come into contact with the bottom surface of the flange portion accommodating portion 43 due to the pushing of the cap member 70 to hinder ventilation.
In the present embodiment, a wiper 73a composed of a jagged protrusion (or groove) is provided on the entire circumference along the inner peripheral surface of the elastic airtight piece 73, and when not pressed as shown in FIG. The airtightness between the outer peripheral surface of the waterproof annular wall 43a is improved.
That is, the wiper 73a provided at the skirt portion of the elastic airtight piece 73 adheres with an appropriate pressure over the entire circumference of the non-concave surface (portion where the concave cut is avoided) of the uneven waterproof annular wall 43a. , Prevents water from entering inside when in close contact. Further, when the button B is pushed in, the close contact state is released, and a ventilation path between the waterproof annular wall 43a and the elastic airtight piece 73 can be secured.

Next, FIG. 12 is a cross-sectional view showing a venting mechanism and a waterproof structure according to another embodiment of the present invention, and FIGS. 13 (a), (b) and (c) are views of a valve member constituting the venting mechanism. FIGS. 14A, 14B, and 14C are an external perspective view, a bottom perspective view, and a partial cross-sectional perspective view of the cap member, respectively. FIG. 15A and FIG. 15B are an external perspective view and a partial cross-sectional view showing the configuration of the flange portion accommodating portion.
The same parts as those in the above embodiment will be described with the same reference numerals.
As shown in FIGS. 12 and 13, the valve member 50 according to the present embodiment forms a ring-shaped cavity 51 a having a large volume inside the flange 51, and communicates the ring-shaped cavity 51 a with the outside. In order to increase the opening area of the outer opening 51b to be made, the lower surface of the flange portion is opened annularly by partially removing the wall portion located on the lower surface side of the cavity portion 51a in the embodiment. . A peripheral wall hole 51c communicating with the cavity 51a is formed in the peripheral wall of the flange portion. A stepped portion 51d is projected on the inner diameter side of the hollow portion 51a.
As shown in FIG. 12, the cavity 51 a communicates with an opening at one end (outer end) of the shaft member 55. When the cap member 70 made of an elastomer or the like is not pressed, the open / close piece 72 provided on the cap member is brought into pressure contact with the lower surface of the stepped portion 52d provided on the outer periphery of the one end portion of the shaft member 55. Communication with is blocked. Further, the peripheral wall hole 51c is sealed by the inner wall of the accommodation space 70a.

Even if the distal end portion (inner end portion) of the shaft member 55 of the valve member 50 is opened as shown in the figure, and this open portion is closed by a screw (bolt or other airtight member) 56 as in the above embodiment. Alternatively, it may be in a closed state without providing an opening during manufacture. Further, the outer end of the shaft member 55 of the present example is different from the shaft member of the above embodiment in that the outer end of the shaft member 55 penetrates to the top of the flange portion 51. However, the opening 51e at the top of the flange portion accommodates the cap member. Since it is sealed by the inner wall of the space 70a, the presence or absence of the opening 51e at the top of the flange does not affect the airtightness.
By comprising in this way, when forming the hollow part 55a in the inside of a shaft member by cutting, since it can drill with a drill from the top part of a flange part, a manufacturing effort can be reduced. At this time, by stopping the drilling before the inner end portion of the shaft member, the inner end portion of the shaft member can be kept closed, and a screw or the like as a closing means becomes unnecessary. By providing the opening 51e at the top of the flange portion, the hollow portion 55a can be made larger in diameter, and the intake / exhaust amount of air when the cap member is pushed in can be increased. When fixing the screw by opening the tip of the shaft member, the inner diameter of the hollow portion 55a needs to be smaller than the screw diameter because it is necessary to form a female screw and ensure the tightening strength of the screw. In the case of drilling from the top of the flange portion, drilling can be performed only from the top of the flange portion, and the inner diameter of the hollow portion can be increased as much as possible.
In addition, since the waterproof annular wall 43a and the elastic airtight piece 73 constituting the waterproof structure 90 exist, it is not always necessary to strictly seal the outer opening 51b with the opening / closing piece 72 in order to maintain the waterproof property. That is, waterproofness can be secured even when the opening / closing piece 72 opens the outer opening 51b to some extent when the cap member is not pushed in. Moreover, although the surrounding wall hole 51c is sealed by the inner wall of the accommodation space 70a, the surrounding wall hole may be sealed to such an extent that waterproofness can be ensured.
In FIG. 12, a step portion is provided on the outer periphery of the shaft member, and the E-ring (washer) 82 is engaged with the step portion, thereby positioning and locking the valve member 55.
The hollow portion in claim 4 is not only the hollow portion 51a formed in the flange portion 51 in the embodiment of FIGS. 6 to 11, but also the ring-shaped hollow portion 51b in the embodiment of FIGS. Is also included. The difference between them is only the difference in the opening amount and the opening shape of the outer opening 51b formed on the lower surface side.

By enlarging the volume of the hollow portion 51b and the opening amount of the outer opening portion 51b, the flow efficiency (exhaust amount) of air when the cap member is pushed and the open / close piece 72 is deformed to the open state is greatly increased. be able to. Therefore, the space S between the core piece 20 and the case piece 4 can be communicated with the outside air, and the responsiveness and operability when blocking the communication can be improved.
In the above embodiment, the inner diameter side ribs 76 protrude from the lower surface of the opening / closing piece 72 constituting the cap member 70 at a predetermined pitch in the circumferential direction. However, in the present embodiment, the inner diameter side ribs 76 are removed. Yes. The reason is that, as shown in FIG. 14, the shape of the flange portion accommodating portion 43 provided on the case piece 4 side is partially improved.
That is, in the present embodiment, as shown in FIG. 15, a plurality of protrusions 46 a extending radially from the through hole 41 in the center portion to the outer diameter direction are formed on the bottom surface of the flange portion accommodating portion 43. By forming the ventilation groove 46b, a large air passage is ensured between the opening / closing piece 72 and the bottom surface of the flange housing portion when the cap member 70 is pushed in. That is, instead of the inner diameter side rib 76 in the embodiment of FIGS. 10 and 11, the protrusion 46a and the groove 46b are provided on the flange portion accommodating portion side.

According to the ejaculation promoting apparatus of the present invention having the above-described configuration, the opening / closing unit 2 can be opened to expose the inner surface of the core piece, so that the inside of the core piece is exposed and washed to every corner. It can be used repeatedly without causing hygiene problems. When a bag-shaped core member made of a soft resin is placed in a hard container like a conventional ejaculation promoting device, cleaning is difficult, but in the present invention, a type in which a core piece is housed in a hard container However, it can be washed and can be used repeatedly.
Further, since the lotion can be applied in the recess 24 before the core piece is closed, the lotion can be injected to every corner, and workability can be improved.
In addition, since the core member is a non-bag-shaped body and exposes the recess 24 when opened, a mold having a simple structure should be used when the core piece 20 is manufactured by injection molding. Therefore, it is easy to give variations to the inner surface shape of the core piece, such as forming complicated protrusions, wrinkles, etc., and the usability can be enhanced.

In the present invention, the elastic porous member 10 is disposed in the space S between the core piece 20 and the case piece 4, and the space S is communicated with the outside air via the venting mechanism 40, or the non-communication state is established. Therefore, when the venting mechanism is closed, the elastic porous member 10 functions as an air cushion, and applies appropriate pressure and stimulation to the penis reciprocating in the insertion space 21 to provide sperm. The collection effect can be enhanced.
In addition, since the elastic porous member 10 is lighter than the gel-like resin material constituting the core piece, the ejaculation promoting device can be reduced in weight to improve operability and handleability. Compared with the low price, the cost can be reduced.
