Description

[Technical Field]

[0001] The present invention relates to an ejaculation promoter and a method for manufacturing an ejaculation promoter. More specifically, the present invention relates to an ejaculation promoter that stimulates and induces ejaculation by stimulating the male penis and can also be used as a sperm (semen) collection device, and a method for manufacturing an ejaculation promoter. [Background technology]

[0002] Ejaculation promoters or sperm (semen) extractors (hereinafter sometimes simply referred to as "ejaculation promoters, etc.") are internal components inserted into the penis, and various internal structures have been designed to suit the size and shape of the penis in order to improve adhesion and stimulation. Furthermore, as sperm extractors (sperm extractors, sperm collection devices, etc.), such ejaculation promoters are considered extremely important not only from the standpoint of medical research and treatment, but also from the standpoint of social demands such as the prevention of sex crimes by satisfying personal sexual desires.

[0003] Here, known examples of conventional ejaculation promoters include an interior member made of a synthetic resin such as an elastically deformable elastomer, which has an insertion opening for inserting the penis and an insertion section that forms a cylindrical space connected longitudinally to the insertion opening, arranged in a space formed in a cylindrical exterior case with a cushioning material inserted therein, and the interior wall of the insertion section of the interior member is formed with a plurality of small protrusions and folds that resemble the internal shape of a woman's vagina (see, for example, Patent Documents 1 and 2).

[0004] The small protrusions and folds formed on the inner wall of the insertion part of the interior member are shaped to mimic the structure of the vagina by, for example, presenting straight or wavy ribs or polyp-like small protrusions and folds, so that when the penis is inserted into the insertion part of the interior member, it is stimulated in the same way as if it were inserted into the vagina.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-112317 [Patent Document 2] Patent Publication No. 2021-126485 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0006] Here, the interior components need to be fixed to the exterior case, and if this fixing is unstable, the interior components may move unnecessarily inside the exterior case during use, which could affect the usability.

[0007] The interior member is generally fixed to the exterior case by fixing the main body, which has the insertion portion formed inside, to the inner wall of the exterior case, or by fixing the disk-shaped flange, which has the insertion opening, to the opening of the exterior case. However, the former method is cumbersome, and fixing the main body to the exterior case affects the user experience, so the latter method has been used more often.

[0008] When fixing a disk-shaped flange to an outer case, a method of fixing the periphery of the flange to the edge of the opening has often been used. However, this requires, for example, forming a special shape for the periphery of the flange and separately forming a member or the like to physically sandwich the periphery to the edge of the opening. In this case, the periphery of the flange may be thin-walled, but because the flange is made of a relatively soft elastomer or the like, the strength may be weak, and the periphery may tear during use, resulting in an instability of fixation. In addition, such instability of fixation can lead to a deterioration in usability, which is undesirable.

[0009] The object of the present invention, made in consideration of the above-mentioned problems, is to provide an ejaculation promoter and a method for manufacturing an ejaculation promoter that can stably fix the flange portion of the interior member to the outer case and that is comfortable to use.

[0025] Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings.

[0026] (I) Basic structure of ejaculation promoter 1: Figures 1 and 2 are perspective views showing one embodiment of an ejaculation promoter 1 according to the present invention (Figure 1 is a view from above, and Figure 2 is a view from below), Figure 3 is a view showing the state in which the lid body 3 has been removed from Figure 1, Figure 4 is a view showing the state in which the lid body 3 has been removed from Figure 2, and Figure 5 is a front view showing one embodiment of an ejaculation promoter 1 according to the present invention. Here, in Figure 1 etc., 1 indicates the ejaculation promoter, 2 indicates the exterior case, 3 indicates the lid body, 4 indicates the ring-shaped member, 5 indicates the interior member, 6 indicates the main body, and 7 indicates the flange.

[0027] The ejaculation promoter 1 according to this embodiment can also be used as a device for collecting sperm (semen) (sperm collection device), and as shown in FIG. The outer case 2 has an opening 21 that is open on at least one side in the longitudinal direction and is cylindrical in shape so that it can be held by hand; a removable cover 3 for opening and closing the opening 21 of the exterior case 2; an interior member 5 that is a cylindrical member that is accommodated in an accommodation portion 26 formed inside the exterior case 2, has one end on the side where an insertion opening 51 is formed in the opening 21 of the exterior case 2, and has the other end arranged inside the exterior case 2; The interior member 5 is integrally formed with a main body 6 having an insertion portion 52 formed therein with a space extending from the insertion opening 51 to the inside, and a substantially disk-shaped flange portion 7 formed at one end of the main body 6 on the side where the insertion opening 51 is formed, the interior member 5 and the exterior case 2 are fixed to each other via the flange portion 7 of the interior member 5 and a ring-shaped member 4 having a substantially ring shape attached to the opening 21 of the exterior case 2, The basic configuration is as follows.

[0028] (II) Outer case 2: Fig. 6 is a perspective view showing one aspect of the exterior case 2. As shown in Figs. 1 to 6, in the ejaculation promoter 1, the exterior case 2 is a cylindrical body that has an internal storage section 26 that serves as a space for storing the interior member 5, and is open by the opening 21 on at least one side in the longitudinal direction (in this embodiment, an aspect in which the opening 21 is formed on only one side)

[0029] In the present invention, the term "opening" (opening 21) is a concept that includes the opening itself as well as the periphery and vicinity of the opened space, which are the parts that form such an opening in each component (external case 2, lid 3, ring-shaped component 4, and internal component 5).

[0030] The opening 21 of the outer case 2 is opened and closed by removing the lid 3, which will be described later, which is formed detachably on the outer case 2. As shown in Figure 6 and other figures, a ring-shaped member 4, which will be described later, is attached to the opening 21 of the outer case 2, and the opening 21 and the ring-shaped member 4 are integrated. Therefore, to be precise, the lid 3 is attached to (or removed from) the ring-shaped member 4, but in the present invention, the removal of the lid 3 from the ring-shaped member 4 is considered to be the same as the removal of the opening 21 of the outer case 2, and is described as opening and closing the opening 21 of the outer case 2 by the lid 3.

[0031] The shape of the exterior case 2 is not particularly limited as long as it is a cylindrical shape that can be gripped by the hand of a user (not shown) or the like with the user's penis (not shown) inserted through the opening 21. In this embodiment, as shown in Fig. 1 etc., a middle stage 22 that has a gentle mountain shape in a plan view is formed approximately in the center of the longitudinal direction, and two upper stage portions 23, 24 that have a gentler mountain shape than the middle stage portion 22 and are located on either side of the middle stage portion 22, are formed symmetrically with respect to the center of the middle stage portion 22. By using such a shape, the user can place their thumb and index finger on the boundary 25 between the upper stage portions 23, 24 and the middle stage portion 22, which forms a step, and grip the case, making it easy for the user to grip.

[0032] The opening 21 in the exterior case 2 is substantially circular, and when a ring-shaped member 4 (described later) is attached and integrated, an opening 31 in the lid 3 (described later) is attached and closed, revealing the shape of the lid 3. In this embodiment, an air hole 27 is formed in the top surface, which corresponds to the opposite side of the opening 21 in the longitudinal direction, as shown in Fig. 1 etc.

[0033] (III) Lid body 3: The following describes the lid 3 and how the lid 3 opens and closes the opening 21 of the exterior case 2. FIG.

[0034] As shown in Figures 2 and 7, in this embodiment, the lid body 3 is a cup-shaped (bowl-shaped) member with an opening (opening 31), and as shown in Figure 5, etc., it has an opening 31 of the lid body 3 facing the circular opening 21 of the outer case 2, a flat bottom portion 32 located on the opposite side of the opening 31 in the longitudinal direction, and a side portion 33 formed to extend straight upward in the longitudinal direction from the bottom portion 32, and the opening 31 is formed by the periphery 35 of the continuous side portion 33.

[0035] Furthermore, a hollow, generally cylindrical columnar portion 34 is disposed inside the lid 3 in approximately the center, at a position that corresponds to the insertion opening 51 of the interior member 5 when the lid 3 is attached to the opening 21 of the exterior case 2. By disposing the columnar portion 34 inside the lid 3, positioning of the lid 3 can be accurate when attaching it to the opening 21 of the exterior case 2, and the lid 3 is less likely to come off the opening 21 once attached.

[0036] Furthermore, when the lid body 3 is attached to the opening 21 of the outer case 2, the side portion 33 of the lid body 3 is connected along the upper step portion 24 of the outer case 2 so that the step is not noticeable, and the shape is maintained so that it is easy for the user to grip.

[0037] There are no particular limitations on the means for opening and closing the opening 21 of the outer case 2 using the lid body 3, and in this embodiment, the lid body 3 is removably attached by attaching the inside of the lid body 3 to the edge 461 of the ring-shaped member 4 that is attached to the opening 21 of the outer case 2, thereby opening and closing the opening 21 of the outer case 2 (see also Figure 12 described below in this regard).

[0038] (IV) Ring-shaped member 4 The following describes the ring-shaped member 4. Fig. 8 is a perspective view (viewed from a direction in which the top surface 41 is visible) showing one embodiment of the ring-shaped member 4, Fig. 9 is a perspective view (viewed from a direction in which the bottom surface 42 is visible) showing one embodiment of the ring-shaped member 4, Fig. 10 is a plan view of the ring-shaped member 4, Fig. 11 is a cross-sectional view of the upper view of Fig. 10, and Fig. 12 is an explanatory diagram showing the attachment (including fixation) of the exterior case 2 and the lid body 3 to the ring-shaped member 4.

[0039] Note that the upper view of Figure 10 corresponds to a view of the ring-shaped member 4 from above (a view showing the upper surface 41), the lower view of Figure 10 corresponds to a view of the ring-shaped member 4 from below (a view showing the lower surface 42), the upper view of Figure 11 corresponds to a cross-sectional view AA of the upper view of Figure 10, and the lower view of Figure 11 corresponds to a cross-sectional view BB of the upper view of Figure 10 (note that the cross-sectional view CC of the upper view of Figure 10 corresponds to the upper view of Figure 20 described below).

[0040] The ring-shaped member 4 is a substantially annular (ring-shaped) member having a hollow portion 43 in the approximate center for inserting the main body portion 6 of the interior member 5, and also having flat upper and lower surfaces 41 and 42, with a cavity 47 formed inside. The side surface 44 is also flat, but in this embodiment, the side surface 44 is doubled, with an outer first side surface 441 and an inner second side surface 442 disposed with a gap 45 therebetween.

[0041] The ring-shaped member 4 is arranged in the opening 21 of the outer case 2, and specifically, is fixed by inserting the edge 28 (see Figure 6, etc.) of the opening 21 of the outer case 2 into the gap 45 between the double first side surface 441 and the second side surface 442.

[0042] As described above, by attaching the ring-shaped member 4 to the opening 21 of the outer case 2, the ring-shaped member 4 essentially forms the opening 21 of the outer case 2, and the lid body 3 is also detached from the ring-shaped member 4 attached to the opening 21 of the outer case 2, thereby opening and closing the outer case 2.

[0043] As shown in Figure 11 etc., gap 45 of ring-shaped member 4 has a bottom surface 46 formed therein. Also, edge 461 is formed extending downward from the outer periphery of bottom surface 46 (inside the first side surface), and as shown in Figure 12, lid body 3 can be attached by attaching the inside of lid body 3 to edge 461, thereby opening and closing opening 21 of exterior case 2, as described above.

[0044] The ring-shaped member 4 has a hollow cavity 47 inside, and in this embodiment, the upper surface 41 and the lower surface 42 each have a plurality of holes H formed therein that are airtightly connected to the internal hollow cavity 47. In this embodiment, the upper surface 41 and the lower surface 42 of the ring-shaped member 4 have approximately rectangular holes H of the same size (hole H1 formed on the upper surface 41, hole H2 formed on the lower surface) formed at equal intervals via regions A (region A1 formed on the upper surface 41, region A2 formed on the lower surface) formed at the boundaries between adjacent holes H.

[0045] In this embodiment, the hole H1 formed in the upper surface 41 and the hole H2 formed in the lower surface 42 are not formed at the same position when viewed in the longitudinal direction. Note that, in the present invention, "the same position in the longitudinal direction" means, for example, when the hole H1 formed in the upper surface 41 is viewed from directly above the upper surface 41, only the hole H2 formed in the lower surface 42 is visible, and the area A2 (between the holes H2) present on the lower surface 42 cannot be seen at all.

[0046] 10 is a view of the ring-shaped member 4 as seen from above, but taking the area surrounded by the dotted line in Fig. 10 as an example, when hole H1 formed in upper surface 41 is viewed from directly above upper surface 41 (this figure is a view from directly above; the same applies below), not only can hole H2 formed in lower surface 42 be confirmed, but area A2 (between holes H2) present on lower surface 42 can also be confirmed, so it can be said that hole H1 formed in upper surface 41 and hole H2 formed in lower surface 42 in the ring-shaped member 4 shown in this embodiment are not "at the same position in the longitudinal direction." Note that, for ease of understanding, area A2 is indicated with a dot (·), and the line pointing to A2 in the area surrounded by the dotted line in the upper view of Fig. 10 is also dotted.

[0047] 10 is a view of the ring-shaped member 4 flipped 180 degrees from the top of Fig. 10 and viewed from below (the opposite direction), but for example, when hole H2 formed in lower surface 42 of ring-shaped member 4 is viewed from directly above lower surface 42, not only is hole H1 formed in upper surface 41 visible, but area A1 (between holes H1) present on upper surface 41 can also be seen, and it can be said that hole H2 formed in lower surface 42 and hole H1 formed in upper surface 41 of ring-shaped member 4 shown in this embodiment are not "at the same position in the longitudinal direction." Note that, for ease of understanding, area A1 is indicated with a dot (·), and the line pointing to A1 in the area surrounded by the dotted line in the lower diagram of Fig. 10 is also dotted.

[0048] In this embodiment, hole H1 formed in upper surface 41 and hole H2 formed in lower surface 42 are not formed at the same position in the longitudinal direction, and therefore are arranged so that when hole H1 formed in upper surface 41 is viewed from directly above upper surface 41, region A (region A2) between holes H2 and H2 present on lower surface 42 can be confirmed. Similarly, when hole H2 formed in lower surface 42 is viewed from directly above lower surface 42, region A (region A1) between holes H1 and H1 present on upper surface 41 can be confirmed.

[0049] In this manner, in this embodiment, holes H (H1, H2) that pneumatically communicate with the internal cavity 47 are formed in each (both) of the upper surface 41 and the lower surface 42 of the ring-shaped member 4 (multiple holes are formed in this embodiment), so that when the interior member 5 (described below) is molded and the ring-shaped member 4 is attached by insert molding, the constituent material of the interior member 5 (the resin material that makes up the interior member 5) enters the internal cavity 47 of the ring-shaped member 4 from the holes H in the upper surface 41 and the lower surface 42 as part of the interior member 5 (the flange portion 7 thereof), ensuring that the ring-shaped member 4 and the interior member 5 are integrated together, thereby making it possible to provide an ejaculation enhancer 1 in which the interior member 5 and the exterior case 2 are securely fixed together.

[0050] As shown in Figs. 14 and 15 which will be described later, the flange portion 7 of the interior member 5 and the ring-shaped member 4 are fixed and integrated (fixed and integrated) by a part of the flange portion 7 entering the inside of the ring-shaped member 4 through a hole H1 in an upper surface 41 and a hole H2 in a lower surface 42 of the ring-shaped member 4 in a state where the main body portion 6 of the interior member 5 is inserted into the hollow portion 43 of the ring-shaped member 4.

[0051] Specifically, the main body 6 of the interior member 5 is inserted into the hollow portion 43, and portions of the flange portion 7 enter through the multiple holes H formed in the upper surface 41 and the lower surface 42, thereby fixing the flange portion 7 to the ring-shaped member 4 and fixing (the flange portion 7 of) the interior member 5 to the ring-shaped member 4. As will be described later, by fixing the ring-shaped member 4 to the opening 21 of the exterior case 2 with (the flange portion 7 of) the interior member 5 fixed to the ring-shaped member 4 in this manner, the interior member 5 is reliably and stably fixed to the opening 21 of the exterior case 2, and the flange portion 7 will not tear off during use, causing the interior member 5 to come off from the exterior case 2. Furthermore, there is no need for the assembly work of clamping the periphery of the flange portion 7 into the opening 21 of the exterior case 2, simplifying the assembly work and resulting in an ejaculation promoter 1 with excellent operability.

[0052] In this embodiment, the positions of the hole H1 on the upper surface 41 and the hole on the lower surface of the ring-shaped member 4 are shifted, and the hole H2 on the lower surface 42 is not located directly below the hole H1 on the upper surface 41 (the area A2 formed between the holes H2 and H2 is located), and the hole H1 on the upper surface 41 is not located directly above the hole H2 on the lower surface 42 (similarly, the area A1 formed between the holes H1 and H1 is located). Therefore, the hole formed on the upper surface and the hole formed on the lower surface of the ring-shaped member 4 are not formed at the same position in the longitudinal direction.

[0053] With this configuration, when this ring-shaped member 4 is attached to an injection mold (not shown) and insert-molded, and the constituent material of the interior member 5 (the resin material that constitutes the interior member 5) is filled into the cavity 47 inside the ring-shaped member 4 from the hole H1 in the upper surface 41 and the hole H2 in the lower surface 42, the region A between the holes H acts as a sort of wall through which the filled constituent material flows, preventing it from leaking out from inside the ring-shaped member 4. This makes it easier for the constituent material of the flange portion 7 (the constituent material of the interior member 5) to remain in the cavity 47 inside the ring-shaped member 4, so that the constituent material can be efficiently fixed integrally with the interior member 5 (the flange portion 7 of the interior member 5).

[0054] In this embodiment, the hole H1 formed on the upper surface 41 of the ring-shaped member 4 and the hole H2 formed on the lower surface 42 are both formed in a series of multiple holes at a predetermined interval (which becomes area A (A1, A2)).The predetermined intervals may be, for example, equal intervals (the same intervals) or random intervals, and are not particularly limited.However, considering ease of manufacturing and the efficient implementation of the above-mentioned effects, it is preferable to form them at equal intervals.Here, if the hole H is approximately rectangular, etc., the ``interval'' may be determined by the interval (distance) between adjacent sides.However, depending on the shape of the hole H, it may be difficult to determine the interval (distance) based on the interval (distance) between adjacent sides.In such cases, it may be determined by the interval (distance) between the centers of the holes H.

[0055] Furthermore, for example, when hole H is made to have a substantially rectangular shape, it is preferable to form region A so that the width is 1 / 1 to 1 / 4 of the width of hole H, so that hole H1 formed on upper surface 41 and hole H2 formed on lower surface 42 are not formed at the same position when viewed in the longitudinal direction. It is more preferable to form region A so that the width is 2 / 3 to 1 / 3 of the width of hole H, and particularly preferable to form it so that it is 1 / 2 to 1 / 3.

[0056] The shape and size of the holes H are not particularly limited, but a shape that allows the constituent material of the interior member 5 (flange portion 7) (the resin material that constitutes the interior member 5 (flange portion 7)) to easily enter during insert molding, such as a circle, an ellipse, or a polygon (a quadrilateral such as a triangle or rectangle, a pentagon, or a hexagon, etc.) and size can be appropriately selected. Among these, it is preferable to form the holes H in a substantially quadrilateral shape (a rectangular shape, a square shape, a trapezoid including an isosceles trapezoid, etc.) because this allows the molten constituent material to pass through efficiently and makes it easy to form the holes H at equal intervals (the shape of the regions A is also equal).

[0057] There is no particular limit to the number of holes H, and it is sufficient that one or more holes H are formed on at least one of the upper surface 41 and the lower surface 42 (in this embodiment, holes are formed on both the upper surface 41 and the lower surface 42), with 2 to 25 being preferred, and 3 to 20 being evenly preferred, but the number is not particularly limited. When multiple holes H are formed on the upper surface 41 or the lower surface 41, as in this embodiment, it is preferable that the same number of holes H are formed on both surfaces, and that the holes H are formed evenly at equal intervals.

[0058] Furthermore, it is preferable that the holes H on the upper surface 41 and the lower surface 42 (hole H1 on the upper surface 41 and hole H2 on the lower surface 42) are formed in a common configuration (layout) on the upper surface 41 and the lower surface 42. Here, "common configuration" means that the size and number of holes H1 formed on the upper surface 41 and holes H2 formed on the lower surface 42 are common, and that the width, shape, etc. of the area A between the holes H (area A1 formed on the upper surface 41 and area A2 formed on the lower surface 42) are also common.

[0059] The exterior case 2, lid 3, and ring-shaped member 4 described above can be made of, for example, conventionally known synthetic resins or metal materials, and from the standpoints of lightness, processability, cost, etc., it is preferable that they be made of synthetic resins, etc. For example, the exterior case 2 can be made of high-density polyethylene (HDPE), etc., and the lid 3 and ring-shaped member 4 can be made of synthetic resins (thermoplastic resins, etc.) such as polyolefin resins such as polypropylene (PP) and ABS (acrylonitrile butadiene styrene), but are not particularly limited to these.

[0060] (V) Interior material 5: Next, we will explain the interior member 5 that is housed in the housing section 26, which is the space inside the exterior case 2. Fig. 13 is a view of the interior member 5 from the direction of the insertion opening 51, and Figs. 14 and 15 are views showing the internal structure of the ejaculation promoter 1. Fig. 13 shows the interior member 5 and the ring-shaped member 4 integrated together. Figs. 14 and 15 have different cross sections; Fig. 14 shows the state in which part of the flange portion 7 has entered through hole H1 (in the upper surface 41) of the ring-shaped member 4, and Fig. 15 shows the state in which part of the flange portion 7 has entered through hole H2 (in the lower surface 42) of the ring-shaped member 4.

[0061] The interior member 5, which constitutes the ejaculation promoter 1 according to this embodiment and is generally called the core member, is housed in the housing section 26, which is a space formed inside the exterior case 2, and is a cylindrical member with one end where the insertion opening 51 is formed located in the opening 21 of the exterior case 2 and the other end located inside the exterior case 2.

[0062] A substantially disk-shaped flange portion 7 is formed at one longitudinal end of the interior member 5 (the end located on the opening 21 side of the exterior case 2), and as shown in Fig. 13 etc., an insertion opening 51 is formed in the approximate center of the flange portion 7. Furthermore, as shown in Figs. 14 and 15, an insertion portion 52 connected to the insertion opening 51 is formed inside the interior member 5.

[0063] In this embodiment, as shown in FIG. 14 etc., it is composed of a main body 6 formed with an insertion section 52 having a space for inserting the user's penis (not shown), and a substantially disk-shaped flange 7 formed at one end of the main body 6, and the main body 6 and flange 7 are integrally formed.

[0064] The interior member 5 has a body 6 that is generally rod-shaped (or generally cylindrical) so that it can be accommodated in the accommodation section 26 of the exterior case 2, and a flange 7 at one end of the body 6; however, in general, accommodation section 26, which is the space formed between the exterior case 2, is often filled with a buffer material B, typically a sponge, in the gap between the exterior case 2 and the interior member 5. Due to the presence of the buffer material B, the interior wall surface of the exterior case 2 and the interior member 5 are not actively fixed together in this embodiment.

[0065] The interior member 5 has an insertion section 52 formed in the longitudinal direction so as to connect to an insertion opening 51 formed approximately in the center of the flange section 7, and a portion (stimulation section 53) that stimulates the user's penis (not shown) is formed on the inner wall of the insertion section 52. Examples of the shape of the portion that stimulates the penis (stimulation section 53) include, for example, protrusions, folds, warts, and bellows shapes that imitate the internal shape of a woman's vagina, and these stimulation sections 53 can be formed in a predetermined arrangement. Figure 14 and other figures show an embodiment in which a wart shape, which is an example of stimulation section 53, is formed in a predetermined arrangement.

[0066] It is preferable that the stimulation section 53 adopts a different shape and arrangement near the insertion opening 51 and near the approximate center of the insertion section 52. In this way, it is possible to give a different type of stimulation to one part of the penis (for example, the glans) than to other parts.

[0067] The material constituting the interior member 5 including the flange portion 7 is ideally one with suitable elasticity, stretchability, and flexibility, and is preferably made of, for example, gel-like resin materials such as various elastomers (styrene-based elastomers, thermoplastic elastomers, etc.), gel-like rubber, various rubber materials, silicone-based resins, polystyrene-based resins, etc. Also, for example, the constituent materials (constituting resin materials) of the interior member (cylindrical member) disclosed in JP 2016-96835 A can be used.

[0068] To manufacture the interior member 5, the above-mentioned resin material can be used and an injection molding die capable of forming the shape of the interior member 5 shown in FIG. 13 etc. can be used to easily manufacture the interior member 5 by injection molding or the like.

[0069] Furthermore, in the present invention, the manufacturing of the interior member 5 and the integration with the ring-shaped member 4 are carried out by injection molding with the ring-shaped member attached to an injection molding die, that is, by insert molding, it is possible to obtain the interior member 5 in which the flange portion 7 and the ring-shaped member 4 are integrated. An example of this will be explained below.

[0070] (VI) Manufacturing of the interior member 5 and integration with the ring-shaped member 4: An example of a means for manufacturing the interior member 5 and fixing and integrating it with the ring-shaped member 4 will be described below. The manufacturing of the interior member 5 and fixing and integrating it with the ring-shaped member 4 is carried out by attaching the ring-shaped member 4 to an injection molding die (hereinafter, may be simply referred to as a "die"), molding (manufacturing) the interior member 5 by so-called insert molding, and integrating the flange portion 7 of the interior member 5 and the ring-shaped member 4.

[0071] in particular, The manufacturing of the interior member 5 and the fixing and integration of the interior member 5 and the ring-shaped member 4 are a step of attaching the ring-shaped member 4 to a core mold 8 for forming the shape of the interior of the interior member 5 and the flange portion 7; a step of attaching a frame mold 9 for forming the outer shape of the interior member 5 to the core mold 8 to which the ring-shaped member 4 is attached, and clamping the mold; a step of injecting a constituent material of the interior member 5 in a molten state into the interior of the frame mold 9, the constituent material forming the shape of the interior member 5, and also entering the cavity 47 inside the ring-shaped member 4 from the hole H formed in the ring-shaped member 4 attached to the core mold 8, thereby forming a part of the flange portion 7; cooling the molten constituent materials; The basic configuration includes:

[0072] (i) a step of attaching the ring-shaped member 4 to a core mold 8 for forming the shape of the interior of the interior member 5 and the flange portion 7: Figure 16 is a diagram showing one embodiment of the core mold 8. The core mold 8 shown in Figure 16 is a mold including portions that form the shape of the interior of the interior member 5 and the flange portion 7 of the ejaculation promoter 1. In the case of the ejaculation promoter 1 shown in Figures 1 and 14, the portion that will form the shape of the interior of the interior member 5 includes the portion that will form the shape of the insertion portion 52, etc. (insertion portion, etc., forming portion 81) and the flange portion forming portion 82. The flange portion forming portion 82 also forms the shape of the insertion opening 51.

[0073] To manufacture the interior member 5 attached to the ring-shaped member 4, first, a preformed ring-shaped member 4 is attached to the core mold 8 shown in Fig. 16, as shown in Fig. 17. Fig. 17 is a diagram showing the state in which the ring-shaped member 4 is attached to the core mold 8, and the ring-shaped member 4 is attached with its upper surface 41 facing up (toward the tip of the insertion portion etc. forming portion 81) so that it fits into the ring-shaped member attaching portion 83 (see Fig. 16) formed above the bottom surface of the flange portion forming portion 82.

[0074] (ii) a step of attaching a frame mold 9 for forming the outer shape of the interior member 5 to the core mold 8 to which the ring-shaped member 4 is attached, and clamping the mold: The frame mold 9 for forming the shape of the interior member 5 is a metal mold, and is a mold that can form the external shape of the interior member 5. Fig. 18 is a diagram showing the state in which the frame mold 9 is attached to the core mold 8. As shown in Fig. 18, the frame mold 9 is shaped so that it can be placed over the core mold 8 and the core mold 8 to which the ring-shaped member 4 is attached can be attached (fitted) inside it.

[0075] The core mold 8 is attached to the frame mold 9 and clamped. The core mold 8 and frame mold 9 are combined to form the shape of the interior member 5, and the frame mold 9 has an interior member forming portion 91 hollowed out inside to match the external shape of the interior member 5 so that the outer shape of the interior member 5 can be formed.

[0076] (iii) A process in which a constituent material of the interior member 5 is poured in a molten state into the interior of the frame mold 9, and the constituent material forms the shape of the interior member 5, and also enters the cavity 47 inside the ring-shaped member 4 from the hole H formed in the ring-shaped member 4 attached to the core mold 8, thereby forming a part of the flange portion 7: In this manner, with the frame mold 9 with the core mold 8 attached thereto clamped, the constituent material of the interior member 5 (the resin material that constitutes the interior member 5) is injected in a molten state into the interior of the frame mold 9 from the side where a material injection port (not shown) is formed. When injected, the molten constituent material enters the interior of the core mold 8 and the space between the core mold 8 and the frame mold 9, and forms the shape of the interior member 5, including the main body portion 6 (including the insertion port 21, insertion portion 52, stimulation portion 53, etc.) and the flange portion 7.

[0077] In this embodiment, the molten constituent material (the resin material that constitutes the interior member 5) enters the cavity 47 inside the ring-shaped member 4 as part of the flange portion 7 from holes H (holes H1, H2) formed on the upper surface 41 and lower surface 42 of the ring-shaped member 4 attached to the core mold 8, and is solidified by cooling performed in a subsequent process, thereby fixing and integrating the flange portion 7 of the interior member 5 and the ring-shaped member 4. Figure 19 is a diagram showing the state in which the molten constituent material has been filled and the interior member 5 has been formed around the core mold 8.

[0078] 20 is an explanatory diagram showing the flow of the constituent material (resin material) in cavity 47 inside the ring-shaped member. The upper diagram in FIG. 20 is a cross section of the upper diagram in FIG. 10 taken along the CC line, with the flow of the constituent material (resin material) indicated by the black arrows, and the lower diagram schematically shows the state in the upper diagram (excluding the black arrows) where cavity 47 has been filled with the molten constituent material (resin material) (the portion marked with a dot (·) is the molten constituent material (resin material), and becomes part of flange portion 5 (interior member 5)).

[0079] In this embodiment, when the molten constituent material is injected into the mold, as shown in the upper diagram of Figure 20, the constituent material enters the internal cavity 47 through hole H1 in the upper surface 41 and hole H2 in the lower surface 42, forming part of the flange portion 7. In this embodiment, beyond hole H there is region A (A1, A2) on the other surface (the lower surface 42 in the case of the upper surface 41, and the upper surface 41 in the case of the lower surface 42), and region A, which is the portion between holes H and H, acts as a sort of wall through which the molten constituent material (resin material) that has filled the region A flows, and the constituent material also hits region A and remains in cavity 47, making it difficult for it to escape (leak) to the outside.

[0080] 20, even if the molten component material enters cavity 47 through hole H1 formed in upper surface 41, it will collide with region A2 of lower surface 42. Similarly, even if the molten component material enters cavity 47 through hole H2 formed in lower surface 42, it will collide with region A1 of upper surface 41.

[0081] As a result of the above, the molten constituent material (resin material) remains and fills the internal cavity 47, and then, upon subsequent cooling, it solidifies and becomes integrated with the external constituent material that forms the flange portion 7, and as shown in the lower diagram of Figure 20, a part of the flange portion 7 (its constituent material) enters the internal cavity 47 through the hole H of the ring-shaped member 4 and is fixed and integrated.

[0082] (iv) cooling the molten constituent materials: After the injection of the molten constituent material is completed, the material is cooled and solidified, and then the frame mold 9 is opened. The molding temperature may be appropriately determined depending on the constituent material (resin material) used, etc., and is preferably 130 to 190°C, and particularly preferably 160 to 180°C. Cooling may be by water cooling or natural cooling, but water cooling is preferred.

[0083] FIG. 21 is a diagram showing the state in which the frame mold 9 has been removed and the interior member 5 has been formed around the core mold 8. As shown in FIG. 21, when the frame mold 9 is removed, the core mold 8 appears with the interior member 5 formed around it. The constituent material of the interior member 5 (the resin material for forming the interior member 5) covers the insertion portion etc. forming portion 81 in the clamped state, and the insertion portion 52 etc. are formed inside it, and the stimulation portion 53 is formed in the insertion portion 52. In addition, the flange portion forming portion 82 forms the flange portion 7 and the insertion opening 51, which is a hole connected to the insertion portion 52 etc.

[0084] Furthermore, the flange portion 7 is formed by the constituent material of the interior member 5 (of the flange portion 7) entering the cavity 47 inside through holes H formed in the upper surface 41 and the lower surface 42 of the ring-shaped member 4, a part of which was attached to the core mold 8 in advance, and then cooling and solidifying, whereby the flange portion 7 of the interior member 5 and the ring-shaped member 4 are fixed and integrated together.

[0085] Regarding the manufacture of the ejaculation promoter 1, an example of a means for assembling and manufacturing the ejaculation promoter 1 shown in Figure 1 and other figures will be described. In order to insert the main body 6 of the interior member 5 into the hollow portion 43 of the ring-shaped member 4 and house the interior member 5 in the exterior case 2 with the flange 7 integrated with the ring-shaped member 4, the main body 6 of the interior member 5, which is wrapped around with the cushioning material B, is inserted through the opening 21 of the exterior case 2 to house the main body 6 in the housing portion 26 of the exterior case 2, and then the interior member 5 is housed in the exterior case 2 so that the flange 7 integrated with the ring-shaped member 4 appears outside from the opening 21 of the exterior case 2 (the flange 7 is not inserted inside (the housing portion 26) of the exterior case 2, but protrudes outside from the opening 21 of the exterior case 2). Furthermore, by removably attaching the lid 3 to the opening 2, the ejaculation promoter 1 shown in Figure 1 and other figures is obtained.

[0086] In this way, by housing the interior member 5 in the exterior case 2, the flange portion 7 of the interior member 5 is securely fixed to the opening 21 of the exterior case 2 via the integrated ring-shaped member 4, and the interior member 5 is not fixed in any way to the inner wall surface of the exterior case 2, so that the ejaculation promoter 1 with the interior member 5 housed in the exterior case 2 can be easily assembled.

[0087] (VII) How to use the ejaculation enhancer 1: An example of how to use the ejaculation promoter 1 according to this embodiment will be described below. First, the lid 3 of the exterior case 2 of the ejaculation promoter 1 is removed to open the opening 21 of the exterior case 2. In this case, it is preferable to pour and apply a lubricant (lotion, not shown) through the insertion opening 51 of the interior member 5 that is revealed by opening the opening 21, and to spread the lubricant evenly over the insertion portion 52 of the interior member 5. It is also preferable to apply such lubricant to the user's penis (not shown).

[0088] When using a lubricant as described above, when the ejaculation promoter 1 of the present invention is also used as a sperm (semen) collector (sperm collection device) for collecting sperm (semen), it is preferable to use a simple lubricant that does not contain a spermicide and is used primarily for lubrication.

[0089] Next, the user's penis is inserted into the insertion part 52 through the insertion opening 51 formed in the flange part 7, which can be seen through the opening 21 of the open exterior case 2. It is preferable for use that the penis is inserted in a somewhat erect state.

[0090] After inserting the penis from insertion opening 51 into insertion section 52, the user grasps ejaculation enhancer 1 and moves it up and down appropriately, preferably along the longitudinal direction of the penis, whereby the penis is stimulated by stimulation section 53, such as a wart or bellows shape, formed inside insertion section 52 of interior member 5. In addition, when the user grips exterior case 2 of ejaculation enhancer 1, the penis is compressed by interior member 5 through the space in storage section 26 of exterior case 2, transmitting a feeling of tightness.

[0091] After the user ejaculates through the above-mentioned operations, the penis is removed from the ejaculation enhancer 1, and a desired amount of sperm (semen) is collected through the insertion opening 51, and the sperm (semen) remaining in the insertion part 52, which is the internal space of the interior member 5, is washed. The lid 3 is also washed. The sperm (semen) may be collected by inserting a dropper or the like into the insertion opening 51 and sucking it up.

[0092] (VIII) Effects of the present invention: In the ejaculation promoter 1 according to the present invention described above, the interior member 5 and the exterior case 2 are fixed together by fastening them via the flange portion 7 of the interior member 5 and the ring-shaped member 4 attached to the opening 21 of the exterior case 2, and the flange portion 7 and the ring-shaped member 4 are fixed together by inserting a portion of the flange portion 7 into the internal cavity 47 of the ring-shaped member 4 through a hole H formed in at least one of the upper surface 41 and the lower surface 42 of the ring-shaped member 4 with the main body 6 of the interior member 5 inserted into the hollow portion 43 of the ring-shaped member 4. This allows the flange portion 7 of the interior member 5 to be stably fixed to the exterior case 2, and the interior member 5 will not come off the exterior case 2 during use, providing an ejaculation promoter that is comfortable to use. Furthermore, there is no need for the assembly process of clamping the periphery of the flange portion 7 into the opening 21 of the exterior case 2, simplifying the assembly process and resulting in an ejaculation promoter 1 that is easy to use.

[0093] Furthermore, the manufacturing method of the ejaculation promoter 1 according to the present invention manufactures the interior member 5 and fixes and integrates the interior member 5 with the ring-shaped member 4 by allowing the constituent material of the interior member 5 (the resin material that makes up the interior member 5) to define the shape of the interior member 5 and to enter the internal cavity 47 of the ring-shaped member 4 through holes H formed on at least one of the upper surface 41 and the lower surface 42 of the ring-shaped member 4, thereby forming part of the flange portion 7 and integrating it with the ring-shaped member 4. Therefore, the flange portion 7 of the interior member 5 is stably fixed to the exterior case 2, providing a method of manufacturing an ejaculation promoter 1 that preferably achieves the effects described above.

[0094] The ejaculation promoter 1 of the present invention can be used as a device to promote ejaculation in men, but can also be used for medical purposes as a device to collect sperm from men (sperm (semen) collection device (sometimes called a collector, collection tool, etc.)). In that case, it can also promote ejaculation in men with reduced ejaculation ability. In addition, by suppressing men's sexual urges, etc., it can help build a healthy society.

[0095] (IX) Variations of the embodiment: The above-described aspects show only one aspect of the present invention, and the present invention is not limited to the above-described embodiments. It goes without saying that modifications and improvements that have the configuration of the present invention and that can achieve the objects and effects of the present invention are included in the content of the present invention. Furthermore, the specific structure and shape, etc., used when implementing the present invention may be changed to other structures and shapes, etc., as long as the objects and effects of the present invention can be achieved. The present invention is not limited to the above-described embodiments, and modifications and improvements that can achieve the objects of the present invention are included in the present invention.

[0096] In the above-described embodiment, the holes H formed in the upper surface 41 and the lower surface 42 of the ring-shaped member 4 are described using Figure 8 and the like, showing an aspect in which the square-shaped holes H are formed at equal intervals across the region, but the holes H formed in the ring-shaped member 4 are merely examples, and the shape of the holes H can be any shape. Furthermore, the positions of the holes H formed in the upper surface 41 and the lower surface 42 of the ring-shaped member 4 (positions of region A) can also be any position within a range in which part of the flange portion 7 can enter the interior of the ring-shaped member 4 through hole H1 in the upper surface 41 and hole H2 in the lower surface 42.

[0097] Here, in the above-described embodiment, a mode has been described in which a plurality of holes H (H1, H2) that are pneumatically connected to the internal cavity 47 are formed on each of the upper surface 41 and the lower surface 42 of the ring-shaped member 4, and the flange portion and the ring-shaped member 4 are fixed and integrated by a part of the flange portion 7 entering the internal cavity 47 of the ring-shaped member 4 through the hole H1 on the upper surface 41 and the hole H2 on the lower surface 42 (with the main body portion 6 of the interior member 5 inserted into the hollow portion 43 of the ring-shaped member 4). On the other hand, if one hole H is formed on at least one (one surface) of the upper surface 41 and the lower surface 42, it is possible for a part of the flange portion 7 (the resin material constituting the flange portion 7) formed in contact with (or adjacent to) the ring-shaped member 4 to enter the internal cavity 47 through the hole H, thereby fixing and integrating the ring-shaped member 4 together. Therefore, it is not essential that multiple holes H (H1, H2) that are airtightly connected to the internal cavity 47 are formed on each of the upper surface 41 and the lower surface 42 of the ring-shaped member 4; it is sufficient that one hole H is formed on at least one (one surface) of the upper surface 41 and the lower surface 42.

[0098] On the other hand, it is preferable to form multiple holes H on each of the upper surface 41 and the lower surface 42 of the ring-shaped member 4, rather than forming one hole H on at least one (one surface) of the upper surface 41 and the lower surface 42, as this makes the area where each surface 41, 42 of the ring-shaped member 4 comes into contact with the flange portion 7 larger (wider), and since there are multiple holes H, there will naturally be more areas into which part of the flange portion 7 can fit, so the ring-shaped member 4 and the flange portion 7 can be fixed together efficiently and with excellent strength, which is preferable.

[0099] When multiple holes H are formed on each surface, as shown in this embodiment, it is preferable to form the same number of holes H on both surfaces, if possible, at equal intervals, and evenly across the ring-shaped upper surface 41 (lower surface 42), which makes it easier to insert part of the flange portion 7. Furthermore, when the number of holes H is relatively small, the area of ​​each hole H may be increased (for example, a roughly C-shape that follows the hollow portion 43), making it easier to insert part of the flange portion 7.

[0100] In the above-described embodiment, the opening 21 of the outer case 2 is formed on one side in the longitudinal direction (one opening), but the opening 21 may be formed on both sides in the longitudinal direction of the outer case 2 (two openings), and the lid body 3 may also be attached so that the opening 21 can be opened and closed removably.

[0101] In the above-described embodiment, an example of the shape of the part (stimulation part 53) that stimulates the penis and is formed on the inner wall of the insertion part 52 of the interior member 5 has been described with reference to FIG. 13 and the like, in which a wart shape or the like is formed in a predetermined arrangement. However, the shape of the stimulation part 53 may be other than that described above, and any shape that has the potential to provide stimulation can be appropriately adopted. In addition, the specific structure and shape when implementing the present invention may be other structures within the scope that can achieve the object of the present invention. [Industrial Applicability]

[0102] The present invention has extremely high industrial applicability, since it can be used not only for medical purposes but also to help build a healthy society by suppressing male sexual urges, etc. [Explanation of symbols]
