Description

  The present invention relates to a massage tool for male genitals intended to guide ejaculation with a moderate sexual feeling close to sexual activity without excessively stimulating male genitals.

  Conventionally, most male massage devices sold as so-called joke goods give excessive stimulation not found in female genitals for the purpose of amplifying sexual feeling. Moreover, since this kind of massage device has a mode that can be understood at a glance, it brings resistance to purchase and use.

  On the other hand, in order to prevent men's inevitable sexual desire from the standpoint of preventing the spread of AIDS (acquired immune deficiency syndrome) quickly and without resistance, the body is aired only during use. An elastic bag-type massage device for male genitals that can be inflated with hot water or the like has also been proposed (Patent Documents 1 to 3). Such a telescopic bag type is flat when not in use and can be folded small, so that it is easy to protect privacy during storage and disposal.

  By the way, in recent years, the tendency of declining birthrate has become a social problem, and one cause is malfunction on the male side. Among them, the present inventor pays attention to ejaculation disorders for which no clear treatment method has been established. Here, ejaculation disorder refers to a symptom in which ejaculation does not lead to ejaculation in a female genital organ during sexual activity or to the extent that ejaculation is difficult to fertilize. These ejaculation disorders are a problem on the male side, but both men and women are sexually complex, and as a result, they develop into ED (erectile dysfunction) and may lead to sexlessness.

  This ejaculation disorder is also found in healthy men in their 20s and 30s, and can be caused by excessive stimulation using the joke goods as described above or masturbation performed frequently. That is, it is considered that such excessive masturbation acts as a daily routine, and the mucous membrane becomes skinned, the sexual feeling becomes dull, and the habituation to strong stimulation also occurs, resulting in ejaculation disorder in a female genital organ.

  On the other hand, according to the elastic bag type massage device as proposed in Patent Documents 1 to 3, the compression force and the frictional force can be adjusted to an appropriate level depending on the injection amount of air or the like, but the male device is inserted. Since the inner wall of the hole to be smooth is smooth, there is a problem that the stimulation is weak and it is difficult to ejaculate.

  The present invention has been made in view of the above-mentioned problems, and the purpose of the present invention is a man who is less resistant to use and can lead to ejaculation with moderate stimulation from the viewpoint of correct sexuality similar to sexual activity It is to provide a dexterous massage tool.

  In order to achieve the above-described object, the present invention provides a flexible elastomer inner cylinder in which a male genital can be inserted along the central axis by sealing one opening of the outer cylinder inside the bellows-structured resin outer cylinder. And a valve body portion that elastically seats on the distal end side of the outer cylinder with the mouth of the other opening of the outer cylinder as a valve seat, and in conjunction with the extension of the outer cylinder, A means for allowing the valve body portion to be detached from the valve seat was used. In this means, the outer cylinder has a bellows structure that can be expanded and contracted in the axial direction. By extending the outer cylinder, the outer cylinder functions as an intake pump that takes in outside air from the other opening as the volume increases (expands). Functions as a handle. On the other hand, the inner cylinder functions as a massage body that applies a stimulus such as friction or compression to the male genital by an operation such as inserting and sliding the male genital. In the present invention, “elastomer”, which is a material for the inner cylinder, is a concept including at least rubber and resin. In the inner cylinder, when the outer cylinder is extended, the valve body portion on the distal end side is detached from the mouth (valve seat) of the other opening of the outer cylinder, and the intake operation of the outer cylinder is enabled. On the other hand, regardless of whether the outer cylinder is in a stationary state or not, if the outer cylinder is in a stationary state, the valve body portion is seated on the valve seat of the outer cylinder by the elastic force of the inner cylinder and maintains the airtight state of the outer cylinder. And in the state which enclosed gas in the outer cylinder, since an inner cylinder is compressed by the internal pressure, a male instrument can be inserted in an inner cylinder densely. In addition, as the male genitalia is inserted into the inner cylinder, the inner cylinder is gradually expanded from the insertion port toward the distal end side, and the internal pressure of the outer cylinder also increases. As a result, depending on the insertion depth of the male genital The pressure on male genitalia changes. In parallel with this, the internal pressure of the outer cylinder also changes by changing the force with which the outer cylinder is gripped, so that the user himself / herself can adjust the compression force on the male genitals at any time.

  Moreover, this massage tool is planned to be used after applying a lubricant (lotion) to male genitalia, as in the conventional case. In view of this, it is preferable that the portion of the inner cylinder into which the male genitalia is inserted is formed in a corrugated shape, a bellows or a spiral shape so that the lubricant applied to the male genital can stay in the recess.

  Furthermore, it is preferable that the inner cylinder is formed in a thick condom shape in which only the insertion opening is opened. However, in such a case, air may be inadvertently taken in when a male genitalia is inserted or massaged. If massage is performed with air taken in, this air leaks from the insertion opening formed in the inner cylinder, and an abnormal noise may be generated at this time. This abnormal noise hinders the user's feelings. Therefore, in the present invention, a check valve that opens only in the direction from the inside toward the outside is provided in the inner cylinder, and the air inside the inner cylinder is exhausted to the outer cylinder side. According to the means, since the air that has entered the inner cylinder at the time of insertion of the male instrument is transferred to the outer cylinder side through the check valve, it is possible to suppress the generation of abnormal noise at the insertion port, and the movement of the air As a result, the internal pressure of the outer cylinder increases, so that the pressure on the male genitals also increases.

  By the way, since the outer cylinder of the present massage tool has a bellows structure, the entire length can be reduced by compression when not in use. Therefore, it can be used for storage. Furthermore, in order to reliably maintain this compact compressed state, in the present invention, a neck portion is provided at the other opening of the outer cylinder, and a cup body is integrally provided at the neck portion, while a cap that can be joined to the cup body. The body is provided separately, and the outer cylinder and the inner cylinder can be accommodated in a compressed state inside the cup body and the cap body.

  In addition, since the inner cylinder is made of a flexible elastomer, it has a better feel and a higher degree of close contact with male genitalia than a conventional stretchable bag. Furthermore, considering the feel and allergic reaction, it is preferable to use a silicone rubber having a more appropriate flexibility and low irritation to the skin. However, the present invention includes other materials having elasticity and stretchability that do not hinder male massage.

  According to the massage device of the present invention, the outer tube can be stored in a compressed state before use, and the inner tube is always accommodated in the outer tube, so it is difficult to determine that it is a male instrument at first glance, There is little resistance to purchase and use, and privacy is easy to protect. Moreover, it can be made into a use state simply by extending | stretching an outer cylinder, and the pressure degree to the male genital by an inner cylinder can also be changed by the cushion action of the pressure adjustment chamber formed between inner cylinders. . Therefore, the stimulation does not become excessive, and can be led to ejaculation by an appropriate feeling of pressure and frictional resistance. Further, when the extension of the outer cylinder is stopped, the valve body portion of the inner cylinder is seated almost simultaneously, and thereafter, the intake operation of the outer cylinder is disabled unless the outer cylinder is further extended. For this reason, the re-compression is impossible, and the user has no choice but to dispose of it unintentionally.

  In addition, the inner shape of the inner cylinder is designed to allow the lubricant to stay, so that the lubricant applied to the male genitalia will not be drained from the insertion hole of the inner cylinder and the lubricant is applied during the massage. There is no trouble of repairing. Furthermore, since the contact surface with the male genital is complicated by such an inner surface shape, stimulation to the male genital can be improved. In addition, since a check valve is provided in the inner cylinder, even if air enters the inner cylinder, this air is exhausted to the outer cylinder side, so the exhaust sound from the insertion port obstructs the mood during massage. In addition, the internal pressure of the outer cylinder is increased by the exhaust, and this can be used as the male force. In addition, since this check valve can discharge not only gas but also a gel body and a liquid, it is possible to discharge the surplus portion of the lubricant retained in the inner cylinder to the outer cylinder side.

  Furthermore, the cup body integrally attached to the neck portion side of the outer cylinder functions as a handle when the outer cylinder is extended, and can be immediately used from the compressed state. Since the container is composed of the body, the compressed state before use is reliably maintained, and the privacy of the contents is also protected.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an external view of a massage device according to an embodiment of the present invention, and the outline thereof is that an inner cylinder 2 is provided inside an outer cylinder 1 having a body portion 1a having a bellows structure that can be expanded and contracted in the length direction. The cup body 3 is integrally provided at one end of the outer cylinder 1 and the cap body 4 that can be joined to the cup body 3 is provided separately. The cup body 3 and the cap body 4 are formed with engaging grooves 3a and engaging projections 4a that are engaged by rotation on the outer periphery and the inner periphery thereof. This massage device can be accommodated in a compressed state. The joining structure of the cup body 3 and the cap body 4 is not limited to the combination of the engaging protrusion 3a and the engaging groove 4a described above, and may be a screw joining structure. Here, the cap body 4 is not used for massaging except for being used as a separate body and used when the present massage tool is accommodated before use. On the other hand, the cup body 3 is integrated with the outer cylinder 1 by fitting with a joint which will be described later, and the cup body 3 is used for extending the outer cylinder 1 when the massage tool is brought into use from the compressed state. It also functions as a handle. However, since the cup body 3 and the cap body 4 do not provide a massage function, they are optional configurations that can be arbitrarily adopted.

  Therefore, according to FIGS. 2 and 3, the description will be given with an emphasis on the more essential configuration of the present invention. 2 is a cross-sectional view of the use state, and FIG. 3 is a cross-sectional view of the state in which the outer cylinder 1 is extended to make the use state. In these drawings, 1 is a bellows structure of the body 1a as described above. An outer cylinder, which is molded from a relatively soft synthetic resin. Both ends of the outer cylinder 1 are open, and one opening (on the lower side in the drawing) has an inward flange portion 1c around which an annular groove 1b is provided. It is formed thicker than 1a or the like. On the other hand, the other opening (upper side in the drawing) of the outer cylinder 1 functions as an intake port 1d as described later. In the present embodiment, cylindrical neck portions 1e and 1f whose diameters are reduced in two steps toward the outside toward the outside of the intake port 1d (the other opening) are formed integrally with the body portion 1a. Among these neck portions, the lower large-diameter neck portion 1e functions as an intake passage when the inside sucks outside air, and the upper small-diameter neck portion 1f is the connection portion 2e of the cup body 3 and the inner cylinder 2. It functions as a connecting part.

  Next, 2 is an inner cylinder, and is provided with an insertion part 2a of a male genitoid formed in a thick condom shape. The inner cylinder 2 has elasticity and stretchability, and can be molded by a flexible elastomer suitable for the use of the human body. A specific material can be exemplified by silicone rubber, but is not limited thereto. is not. The insertion portion 2a of the inner cylinder 2 is inserted from the one opening of the outer cylinder 1 into the outer cylinder 1 along the central axis. An insertion port 2b for male genitalia is formed on the bottom surface side (the lower side in the drawing) of the insertion portion 2a, and the inward flange portion 1c of the outer cylinder 1 is wound around (clamped) around the insertion port 2b. A seal portion 2c that fits into the annular groove 1b so as to seal one opening of the outer cylinder 1 is formed. Further, the seal portion 2c is fixed to the annular groove 1b by a tightening ring 5 wound from the outside thereof, and prevents the seal portion 2c from being detached from the annular groove 1b by turning or the like. On the other hand, the distal end side (upper side in the drawing) of the insertion portion 2a is closed, and the outer peripheral surface on the distal end side is slightly thickened in the radial direction, so that the intake port 1d from the inside of the outer cylinder 1 is in a normal state. The valve body 2d that can be closed elastically is configured. That is, the mouth edge of the intake port 1d functions as a valve seat on which the valve body 2d is seated. Further, a connecting portion 2e protruding inside the small-diameter side neck portion 1f of the outer cylinder 1 is extended at the top of the inserting portion 2a, and an insertion hole 2f is provided through the connecting portion 2e.

  Subsequently, reference numeral 6 denotes a ring-shaped joint that is attached to the small-diameter side neck portion 1f of the outer cylinder 1. The rim flange 1g of the small-diameter side neck portion 1f serves as a retaining stopper, It is to be connected. Moreover, this joint 6 is provided with the insertion pin 6a inserted in the insertion hole 2f formed in the connection part 2e of the inner cylinder 2 in the center hole, and this insertion pin 6a is inserted in the said insertion hole 2f, and a small diameter is inserted. The side neck portion 1f and the connecting portion 2e of the inner cylinder 2 are connected. The joint 6 has a structure in which the insertion pin 6a is divided in two so as to be connectable. After assembling, the insertion pin 6a is inserted into the insertion hole 2f of the connection portion 2e while the small-diameter neck portion 1f is sandwiched from both sides. The joint 6 as shown in the figure is formed by connecting the divided members.

  The operational effect of the massage device having the above-described configuration will be described together with the method of use. First, the outer cylinder 1 and the inner cylinder 2 are fixed to each other by the joint 6 and the tightening ring 5. Is extended, the insertion portion 2a of the inner cylinder 2 made of a flexible material follows and extends in the length direction (see FIG. 3). As the inner cylinder 2 extends, the valve body portion 1d formed on the distal end side moves in a direction away from the intake port 1d of the outer cylinder 1, or / and the inner cylinder 2 is elastically deformed in the diameter-reducing direction. As a result, the valve body portion 1d is detached from the intake port 1d of the outer cylinder 1 and opens the intake port 1d. Then, by the pump action of the outer cylinder 1, intake is performed by following the order of the arrow A and arrow B on the drawing by the amount of volume increase accompanying the extension. Then, if the extension of the outer cylinder 1 is stopped, the valve body 1d again opens the inlet 1d by the elastic restoring force of the outer cylinder 1 and / or the inner cylinder 2 or / and the whole is slightly compressed. The outer cylinder 1 is closed and held in an expanded (expanded) state (see FIG. 2). In addition, when the length of the extended inner cylinder 2 is insufficient, the length can be adjusted by extending the outer cylinder 1 again.

  When the length adjustment is completed by the extending operation of the outer cylinder 1 in this way, a male container appropriately coated with a lubricant is inserted into the inner cylinder 2 from the insertion port 2b. Then, by holding the outer cylinder 1 by hand and sliding it in the axial direction, the male genitalia can be massaged in and out of the inner cylinder 2. At this time, as the male genitalia is inserted, the inner cylinder 2 is gradually expanded from the insertion port 2b toward the distal end side. Since the outer cylinder 1 is in a sealed state, the internal pressure of the outer cylinder 1 increases as the inner cylinder 2 is expanded. Therefore, the deeper the male genital is inserted, the stronger the male genital pressure is squeezed. As described above, according to the present invention, the internal pressure of the outer cylinder 1 changes according to the insertion / extraction of the male genital with respect to the inner cylinder 2 (insertion depth with respect to the inner cylinder 2). The pressure changes. This is similar to the movement of the female genitals (vagina) in actual sexual activity, so that the stimulation is not excessive, and the male genitals can be led to ejaculation with a sexual feeling more similar to sexual activity. In parallel with this, the internal pressure of the outer cylinder 1 can also be changed by changing the force gripping the outer cylinder 1, and the user can perform massage with a desired tightening force.

  Here, in this embodiment, since the body part shape of the insertion part 2b of the inner cylinder 2 is made into a bellows shape like the body part 1a of the outer cylinder 1, the unevenness gives an appropriate stimulus to the male genitalia. Further, since the lubricant applied to the male genitus stays in the recess 2g on the inner surface side, the lubricant does not leak unnecessarily from the insertion port 2b. In addition to the bellows shape described above, the inner cylinder 2 may have a spiral shape or a wavy shape as long as the lubricant can stay therein. It is a selective matter to adopt.

  Furthermore, in the present embodiment, a check valve 2h that opens only in one direction from the inside toward the outside is provided on a part (front end side) of the inner cylinder 2. The check valve 2h in this embodiment is a so-called duckbill valve in which a part of the inner cylinder 2 protrudes outward during molding and a slit is formed at the tip of the protrusion. By configuring such a check valve 2h, air that has entered the inside of the inner cylinder 2 and excess lubricant can be discharged to the outer cylinder 1 side. However, the configuration of the check valve 2h is not limited to a so-called duckbill valve, and the provision of the check valve 2h is an optional item.

  After the massage is performed in this way, the massage tool cannot be returned to the original compressed state again. This is because the outer cylinder 1 is in a sealed state in which the intake port 1d is closed by the valve body portion 2d of the inner cylinder 2, and the sealed state cannot be released by compressing the outer cylinder 1. Therefore, the massage tool is basically disposable so as to ensure hygiene and prevent inadvertent diversion to others, thereby avoiding the transmission of diseases. However, it does not completely exclude that the massage tool is cleaned after use and stored hygienically and used again by the same person.

  The massage device of the present invention can be used not only for preventing ejaculation disorder from the viewpoint of correct sexual feeling, but also for pseudo prior experience of sexual activity and for sexual care for a physically handicapped person.
