It is elastically deformable and has a cylindrical shape. An insertion port S is provided on at least one end surface in the longitudinal direction (see the arrow (→) direction in FIG. 1 and the like), and extends inward from the insertion port S. An insertion portion 21 that serves as a space is formed, and an inner layer 2 on which a portion that stimulates the penis is formed is formed on the inner surface of the insertion portion 21.

Shows. Further, as shown in FIGS. 1 to 3 and the like, the ejaculation accelerator 1 according to the present invention is formed to have at least a two-layer structure so that the outer layer 3 covers the periphery of the inner layer 2. Hereinafter, the configurations of the inner layer 2 and the outer layer 3 constituting the ejaculation accelerator 1 will be described.

(1) Configuration of inner layer 2:
7 is a partially enlarged view of FIG. 6, FIG. 8 is a view showing the positional relationship between the gap 25 of the inner layer 2 and the protrusion 31 of the outer layer 3, and FIG. 9 is a perspective view showing one aspect of the inner layer 2. 10 is a front view showing the internal structure of the inner layer 2, and FIG. 11 is a perspective view showing the internal structure of the inner layer 2. In FIG. 8, in the inner layer 2, the portion corresponding to the void 25 (“・” (point: dot) is the same as in FIG. 1 and the like) and the portion not (“・” are thicker than the others). I am trying to understand the difference from.). Further, only in FIGS. 9 to 11, the outer surface of the inner layer 2 is shown as 2a. As shown in FIGS. 1 to 11 (particularly, FIGS. 1 and 10), the inner layer 2 constituting the ejaculation accelerator 1 is elastically deformable, has a tubular shape, and has one end surface in the longitudinal direction. An insertion port S is provided in the insertion port S, and an insertion portion 21 is formed as a space extending inward from the insertion port S, so that a user's penis (not shown) can be inserted from the insertion portion 21.

As shown in FIGS. 1 and 4, the inner layer 2 is covered with an outer layer 3 having a tubular shape that can be grasped by a user (not shown, the same applies hereinafter) (not shown). The outer layer 3 will be described later.) As shown in FIG. 9 and the like, the inner layer 2 in the present embodiment also has a shape conforming to the outer layer 3 and has a cylindrical shape that can be grasped by the user's hand. ing.

In the present embodiment, the shape of the inner layer 2 is such that the middle diameter portion 22 having a gentle mountain shape in a plan view is in the center at substantially the center in the longitudinal direction, as shown in FIG. The mountain-shaped large-diameter portions 23 and 24 having a larger diameter are formed symmetrically with the small-diameter portion 26 having a smaller diameter than the middle-diameter portion 22 and forming a valley.

As shown in FIGS. 5 and 10, in the present embodiment, the ejaculation accelerator 1 has a portion (stimulation portion X) that stimulates the penis formed on the inner wall of the insertion portion 21. Examples of the shape of the portion that stimulates the penis (stimulation portion X) include a convex portion (projection), a fold shape, a wart shape, a bellows shape, a continuous step shape, and the like. It can be formed in a predetermined arrangement. 5 and 6, FIGS. 7 to 11 and the like show an embodiment in which a bellows shape, a continuous step shape, and the like, which are examples of the stimulating portion X, are formed in a predetermined arrangement.

The portion that stimulates the penis (stimulation portion X) formed on the inner surface (inner wall) of the insertion portion 21 may have a different shape in the vicinity of the insertion port S and in the vicinity of the tip of the insertion portion 21, or the insertion port may be different. The shape and arrangement may be different between the vicinity of S and the vicinity of the substantially center of the insertion portion 21, and the shape and arrangement can be arbitrarily determined. For example, if the vicinity of the insertion port S and the vicinity of the substantially center or the vicinity of the tip of the insertion portion 21 have different shapes, a part of the penis (for example, a glans, etc.) (for example, a glans penis), which is not shown, is of a different type from the other parts. Can be stimulating.

Since the inner layer 2 is visible from the outside via the outer layer 3 described later, it is preferable that the inner layer 2 is colored. In order to color the inner layer 2, a colorant may be added to the constituent material of the inner layer 2 to color the entire surface including the inside of the inner layer 2, or the outer surface of the inner layer 2 may be colored. Details will be described later.

As shown in FIGS. 9 to 11, the outer surface (wall surface) 2a of the inner layer 2 has a gap (hole, slit, etc.) 25 that penetrates to the insertion portion 21, which is a space formed inside the inner layer 2. Are formed in plurality. In the present embodiment, the gap 25 has a diamond shape (diamond (◇) shape) when viewed from the front, so that the diamond-shaped gap 25 reaches from the outer surface of the inner layer 2 to the insertion portion 21 and penetrates therethrough. Multiple are formed.

As described above, the gap 25 penetrating the insertion portion 21 is formed on the outer surface 2a of the inner layer 2, so that the gap 25 forms a patterned design on the inner layer 2 and is combined with the design of the appearance shape of the inner layer 2. Therefore, the inner layer 2 having the design property can be visually recognized from the outer layer, so that the ejaculation accelerator 1 has an excellent design property. In addition, a space is formed on the inner surface (inner wall) of the insertion portion 21 due to the gap 25, and a protrusion formed on the inner surface of another member (in the present embodiment, the inner surface of the outer layer 3) through which the tip penetrates to the insertion portion 21. By changing the nuance of the stimulus by inserting 31) or the like (see FIGS. 7 and 8), it is possible to give a variation to the usability (you can enjoy various usability), and as a result, you can enjoy various usability. The ejaculation accelerator 1 has a good usability.

It is sufficient that one or more voids 25 are formed on the outer surface 2a of the inner layer 2 with respect to the outer surface 2a of the inner layer 2, which improves the design and efficiently imparts variation to the usability. Therefore, it is preferable that a plurality of them are formed as shown in FIGS. 1 and 9 and the like. Further, the shape of the void 25 formed by penetrating from the outer surface 2a of the inner layer 2 to reach the inner insertion portion 21 is not limited to the above-mentioned rhombic shape, and is triangular or square (rectangular) in front view. It can be any shape such as a polygonal shape such as a pentagonal shape, a circular shape, an elliptical shape, a geometrical shape, etc., and when a plurality of voids 25 are formed, the whole shape is formed. It may be a shape common to or a plurality of types, and further, the area and number that can be confirmed from the outer surface 2a of the inner layer 2, and the entire area of the outer surface 2a of the inner layer 2 (including the area of the void 25; the same applies hereinafter). (In consideration of strength and the like, the ratio of the area of the void 25 (total) is preferably half (50%) or less of the total area of the outer surface 2a of the inner layer 2, but is not particularly limited to this. ), Position, etc. can all be determined arbitrarily. Other aspects of the shape of the gap 25 (and the protrusion 31 formed on the inner surface 3a (see FIG. 12 and the like) of the outer layer 3) will be described later with reference to FIGS. 19 and 20.

Further, as shown in FIGS. 5 to 8, in the present embodiment, a triangle (Δ) in front view (also cross-sectional view) formed on the inner surface 3a of the outer layer 3 described later in the gap 25 of the inner layer 2. , ▽) The aspect in which the shaped protrusion 51 is inserted is shown, which will be described later.

Next, the constituent materials and the like of the inner layer 2 will be described. Elastically deformable (among the deformations that occur when a force is applied to an object, the deformation that completely returns to its original shape (elastic deformation) when the force is removed is flexible (as desired). Hereinafter, the outer layer 3 is also free. As the material constituting the inner layer 2 (same as above), it is preferable to use a material having appropriate elasticity, elasticity, and flexibility, and it is preferable to use an elastic polymer (also referred to as a soft resin). As the elastic polymer, for example, a thermoplastic elastomer, an elastomer, a gel-like rubber, a silicone resin, a polystyrene resin, a urethane resin, a soft polyvinyl chloride (PVC) resin, a soft polyolefin resin and the like can be used. .. These elastic polymers may be used alone or in combination of two or more.

As the elastic polymer, it is preferable to use a thermoplastic elastomer, including the outer layer 3 described later, in terms of moldability, cost, and good usability when used as a molded product. Examples of the thermoplastic elastomer include styrene-isoprene-styrene block copolymer (SIS), styrene-butadiene-styrene block copolymer (SBS), and (hydrogenated) styrene-ethylene-propylene block copolymer (SEP). , (Hydrogenized) styrene-ethylene-butylene-styrene block copolymer (SEBS), (hydrogenated) styrene-ethylene-propylene styrene block copolymer (SEPS), (hydrogenated) styrene ethyleneethylene propylene styrene block copolymer weight Combined (SEEPS), styrene-butadiene block copolymer (SBR), (hydrogenated) styrene-butadiene block copolymer (SEB) styrene-isoprene block copolymer (SIR), hydrogenated styrene-isoprene block copolymer It is particularly preferable to use a styrene-based thermoplastic elastomer such as (SEP), styrene-isoprene-styrene block copolymer (SIS). These may be used alone or in combination of two or more.

Also, for example, natural rubber, polybutadiene, polyisoprene, polyisobutylene, neoprene, polysulfide rubber, thiocol rubber, acrylic rubber, urethane rubber, silicone rubber, epichlorohydrin rubber, ethylenepropylene rubber (EPR), ethylenepropylenediene rubber (EPDM). , Butadiene-acrylonitrile-styrene-coreshell rubber (ABS), methylmethacrylate-butadiene-styrene-coreshell rubber (MBS), methylmethacrylate-butylacrylate-styrene-coreshell rubber (MAS), octylacrylate-butadiene-styrene-coreshell rubber ( MABS), siloxane-containing core-shell rubber such as alkyl acrylate-butadiene-acrylonitrile-styrene core-shell rubber (AABS), butadiene-styrene-core-shell rubber (SBR), methyl methacrylate-butyl acrylate-siloxane, etc. Alternatively, rubber obtained by modifying these can be mentioned. These may be used alone or in combination of two or more.

Further, in the present invention, it is preferable that the elastic polymer described above contains a water-absorbent resin (also referred to as a water-absorbent polymer or a water-absorbent polymer) as a constituent material of the inner layer 2. By using an elastic polymer and a water-absorbent resin in combination as a constituent material of the inner layer 2, the elastic polymer can be dispersed in the elastic polymer as a base material when molded as the inner layer 2, and water absorption can be imparted to the inner layer 2. By contacting 2 with a liquid such as water (hereinafter, may be simply referred to as "water or the like"), it becomes a gel and can cause slippage on the surface of the insertion portion 21. Further, since such moderate slippage is common to the case where the lotion is poured into the insertion portion 21, the use of the lotion can be reduced as much as possible, and the lotion can be preferably eliminated.

The water-absorbent resin is not particularly limited, and is, for example, polyacrylic acid-based salt (including a crosslinked product of polyacrylic acid-based salt), polyacrylamide, a hydrolyzate of a starch-acrylonitrile graft copolymer, and carboxymethyl cellulose. Examples thereof include crosslinked products, acrylic acid (salt) -vinyl alcohol copolymers, polyoxyethylene crosslinked products, thermoplastic resins containing polyalkylene oxide units, and the like.

In general, a polymer of acrylic acid has a large number of carboxyl groups and is therefore highly hydrophilic, and the water-absorbent resin preferably contains a polyacrylic acid-based salt. Further, it is particularly preferable to use sodium polyacrylate because it becomes a gel having high water absorption when cross-linked to a network structure as necessary and formed into a sodium salt and exhibits excellent properties. As the sodium polyacrylate, a crosslinked product (sodium polyacrylate crosslinked product) may be used. Sodium polyacrylate is also known as a super absorbent polymer (superabsorbent polymer), and can absorb a large amount of water with a small amount of addition, and is therefore suitable for the object of the present invention.

As the water-absorbent resin, liquid, powder (including powder and granular) and the like can be used, and it is preferable to use powder. By making it into a powder, the surface area is increased, the water absorption capacity is further improved, and the powder is well dispersed in the elastic polymer as a base material. The average particle size is not particularly limited, but is preferably 1 to 1000 μm, and a known shape such as a spherical shape, a plate shape, a fluid-forming fluid, or an indefinite shape can be used.

The content of the water-absorbent resin with respect to the elastic polymer as the constituent material of the inner layer 2 may be appropriately determined depending on the type of the elastic polymer used, the type of the water-absorbent resin, the required characteristics (degree of slippage), and the like. It can be considered that if the content of the absorbent resin is increased, slippage will occur with a small amount of water, but it is generally preferably 1 part by mass or more with respect to 100 parts by mass of the elastic polymer. It is more preferable to contain 100 parts by mass. If the content of the water-absorbent resin is less than 1 part by mass with respect to 100 parts by mass of the elastic polymer, slippage may not occur even if it is brought into contact with water or the like, and if it is more than 100 parts by mass, the content of the elastic polymer is increased. It may exceed the limit, affect the elastic deformation, and may increase the cost slightly.

By increasing the content of the water-absorbent resin, the cost of the water-absorbent resin increases slightly, but there is an advantage that the number of times gelation can be performed increases and the number of times of use can be increased. The content of the water-absorbent resin with respect to the elastic polymer is more preferably 5 to 100 parts by mass with respect to 100 parts by mass of the elastic polymer, which is cost-effective, and in order to enjoy a good usability, the elastic polymer is used. It is even more preferably 5 to 20 parts by mass, and particularly preferably 8 to 20 parts by mass with respect to 100 parts by mass.

In the ejaculation accelerator 1 of the present invention, it is preferable that the inner layer 2 is colored in order to make the shape of the inner layer 2 easily visible from the outside. However, in order to color the inner layer 2, the inner layer 2 is colored. A conventionally known colorant may be added to the constituent material, or the outer surface of the inner layer 2 (see the outer surface 2a in FIG. 9 or the like) may be colored by painting or the like. Considering the simplification of the production of the inner layer 2, it is preferable to add a colorant to the constituent material of the inner layer 2 when coloring the inner layer 2.

Further, a foaming agent may be further added to the above-mentioned constituent materials. By adding the foaming agent, the softness and elasticity of the inner layer 2 become appropriate, and the inner layer 2 can be brought close to human skin. As the foaming agent, conventionally known ones can be used. For example, an inorganic thermal decomposition type chemical foaming agent, a chemical foaming agent such as an organic pyrolytic chemical foaming agent, a physical foaming agent and the like are used. be able to. The same applies to the outer layer 3 described later with respect to the effectiveness of application of the foaming agent.

The content of the foaming agent in the inner layer 2 is not particularly limited and can be appropriately determined according to the required degree of foaming, softness and the like. For example, 0.1 to 50 parts by mass of the elastic polymer. The amount is preferably parts by mass, and particularly preferably 0.1 to 10 parts by mass.

(2) Configuration of outer layer 3:
FIG. 12 shows a front view showing the internal structure of the outer layer 3 (outer layer 3 only), and FIG. 13 shows a perspective view showing the internal structure of the outer layer 3 (outer layer 3 only) (FIGS. 12 and 13 only). , The inner surface of the outer layer 3 is shown as 3a). As shown in FIG. 1 and the like described above, the outer layer 3 constituting the ejaculation accelerator 1 is formed so as to cover the inner layer 2 described above. The inner surface 3a of the elastically deformable outer layer 3 (because both the inner layer 2 and the outer layer 3 are elastically deformable, the ejaculation accelerator 1 formed from them is also elastically deformable) is the elastically deformable inner layer. It is in close contact with the outer surface 2a of 2, and the inner surface 3a of the outer layer 3 has a triangular (Δ, ▽) shape (the same applies to the protrusion 31) in front view (also in cross-sectional view). The protrusion 31 is formed at a position corresponding to the gap 25 of the inner layer 2. As shown in FIGS. 5 to 8 (particularly, see FIGS. 7 and 8), the protrusion 31 has a diamond shape formed on the outer surface 2a of the inner layer 2 with its tip directed toward the insertion portion 21 of the inner layer 2. As described above, it has entered the inside of the void 25 of the diamond (◇) shape). As shown in FIGS. 5 to 8 (particularly, see FIGS. 7 and 8), in the present embodiment, the tip of the protrusion 31 appears (protrudes) in the insertion portion 21 of the inner layer 2. Shows.

In the present embodiment, specifically, a front view (cross section) formed on the inner surface 3a of the outer layer 3 in one of the diamond-shaped (diamond (◇) -shaped) voids 25 formed on the outer surface 2a of the inner layer 2. In view of the eye), the protrusions 31 of a triangle (Δ) and a triangle (▽) (the latter is also called an inverted triangle) are combined one by one to show an aspect of entering the inside thereof.

The outer surface (wall surface) 2a of the inner layer 2 on which the void 25 is formed is in contact with the inner surface 3a of the outer layer 3, and the void 25 formed on the outer surface 2a of the inner layer 2 is formed on the inner surface 3a of the outer layer 3. The protrusion 31 is inserted. In addition, as shown in FIGS. 5 to 8 (see particularly FIGS. 7 and 8), the tip of the protrusion 31 appears at the insertion portion 21 of the inner layer 2, but is on the side of the insertion portion 21 of the inner layer 2. When viewed from the above, the appearance of the tip of the protrusion 31 serves as a portion to be stimulated together with the stimulating portion X formed in the insertion portion 21 of the inner layer 2. That is, in the ejaculation accelerator 1 of the present embodiment, the protrusion 31 or the tip of the protrusion 31 that enters the insertion portion 21 of the inner layer 2 from the outer layer 3 is inserted in the same manner as the stimulation portion X formed in the insertion portion 21 of the inner layer 2. The penis (not shown) inserted into the portion 21 can be stimulated, and a variation in usability can be imparted. The protrusion 31 formed on the inner surface 3a of the outer layer 3 is not limited to the above-mentioned triangular shape, and is a square shape (including a rectangular shape, a square shape, a rhombic shape, etc.) and a pentagonal shape in front view (cross-sectional view). It can be any shape such as a polygonal shape, a circular shape, an elliptical shape, and a geometrical shape. Further, when a plurality of protrusions 31 are formed, they may have a common shape as a whole or a plurality of types, and the area and number, the ratio to the entire outer layer 3, the position, and the like are all arbitrarily determined. be able to.

As shown in FIGS. 5 to 8 described above, the protrusion 31 formed on the inner surface 3a of the outer layer 3 preferably has the tip of the protrusion 31 reaching the insertion portion 21 of the inner layer 2, but does not reach the protrusion 31. Even so, when the user grasps the ejaculation accelerator 1 at the time of use, the tip of the protrusion 31 may touch or not touch the penis (not shown) inserted in the insertion portion 2, and the gap may be formed. Since variations in usability will increase, including the presence of 26, there is no problem even if the tip of the protrusion 31 does not reach the insertion portion 21 of the inner layer 2.

In the present invention, the outer layer 3 is designed so that the inner layer 2 covering the outer layer 3 can be visually recognized from the outside. Since the outer layer 3 is formed in this way, the shape of the inner layer 2 in which the void 25 is formed on the outer surface can be visually recognized from the outside, and the ejaculation accelerator 1 having excellent design is obtained. The outer layer 3 can have any color such as transparent (clear), translucent, and cloudy as long as the inner layer 2 covering it can be visually recognized from the outside, but it is easy to visually recognize and the colorant. It is preferable to make it transparent because it can be added or the number of steps can be reduced.

The outer layer 3 has an insertion port S common to the inner layer 2, and has a cylindrical shape that can be grasped by a user (not shown). In the present embodiment, the shape of the outer layer 3 is the same as that of the inner layer 2 described above, and as shown in FIGS. 1 and 12, the outer layer 3 has a gentle mountain shape in a plan view at substantially the center in the longitudinal direction. With the diameter portion 32 in the center, the mountain-shaped large diameter portions 33, 34 having a diameter larger than that of the middle diameter portion 32 are formed symmetrically with the small diameter portion 36 having a smaller diameter than the middle diameter portion 32 and forming a valley. Has been done. Since the user can hold the small diameter portion 36 or the like, which is a valley, by putting his / her finger on it, the shape is easy for the user to hold.

Among the materials constituting the inner layer 2 described above, it is preferable to use an elastic polymer as a main component of the constituent material of the outer layer 3 which is held in the user's hand and is elastically deformable. As a specific example of the elastic polymer constituting the outer layer 3, it is preferable to use a thermoplastic elastomer, and it is particularly preferable to use a styrene-based thermoplastic elastomer. , The description is omitted. Even when the inner layer 2 contains the water-absorbent resin as the ejaculation accelerator 1, the inner layer 2 and the outer layer 3 have at least a two-layer structure, and the insertion portion 21 into which the penis is inserted is formed. Since it is the inner layer 2, it is not necessary to positively add the water-absorbent resin to the outer layer 3.

As described above, even if the ejaculation accelerator 1 contains the water-absorbent resin for the elastic polymer as the constituent material of the inner layer 2, the water-absorbent resin is not applied to the entire ejaculation accelerator 1 but to the penis. If it is contained only in the inner layer 2 in which the insertion portion 21 to be inserted is formed, the surface of the insertion portion 21 slips due to the contact of a liquid such as water with the insertion portion 21 of the inner layer 2. The effect of adding the water-absorbent resin, such as improving the feeling of use, can be preferably enjoyed, and the cost can be reduced by limiting the amount of the water-absorbent resin added to the inner layer 2. can.

Further, with respect to the outer layer 3 containing the elastic polymer as the main component, the inner layer 2 to which the water-absorbent resin is added basically does not appear to the outside, so that the portion where the ejaculation accelerator 1 is directly gripped is provided with appropriate softness. The force for gripping the outer layer 3 is smoothly transmitted to the inside, and even if a liquid such as water comes into contact with the surface (outer layer 3) that appears outside the ejaculation accelerator 1, the surface is prevented from slipping. Can be done. Here, the "main component" may be 50% by mass or more with respect to the entire constituent material (excluding softening oil), but is preferably 80% by mass or more, and is preferably 85% by mass or more. Is particularly preferable.

As the constituent materials of the inner layer 2 and the outer layer 3, in addition to the above-mentioned materials, a pigment or a colorant (for the outer layer 3, the range in which the inner layer 2 can be visually recognized is within a range that does not interfere with the object and effect of the present invention. ), Stabilizers such as inorganic stabilizers, lubricants, impact resistance improvers, processing aids, crystal nucleating agents, reinforcing agents, flame retardants, cross-linking agents, cross-linking monomers, weather resistance improving agents, UV absorption. Agents, antioxidants, hydrolysis resistance improvers, fungicides, antibacterial agents, light stabilizers, antistatic agents, oil components such as softening oils, antiblocking agents, mold release agents, fragrances, fillers, couplings Various additives such as agents and cross-linking agents can be added as needed.

Further, it is preferable to contain softening oil as a constituent material of the inner layer 2 and the outer layer 3. The softening oil has a function of softening a thermoplastic elastomer (particularly, a styrene-based thermoplastic elastomer) as a base material, and depending on the content, the inner layer 2 and the outer layer 3 (that is, the ejaculation accelerator 1; the same applies hereinafter). The softness (softness) of the inner layer 2 and the outer layer 3 can be adjusted by adjusting the content of the inner layer 2 and the outer layer 3 (the higher the content, the more the inner layer 2 and the inner layer 2 and the softness) can be adjusted. Softness can be imparted to the outer layer 3).

As the softening oil, a conventionally known softening oil capable of softening a thermoplastic elastomer or the like can be used. For example, liquid paraffin or paraffin oil known as a hydrocarbon oil (hereinafter, collectively referred to as "paraffin") can be used. It may be referred to as "based softener"), naphthenic oil (naphthenic softener), aromatic oil (aromatic softener) and the like can be used. Among these, it is preferable to use a paraffin-based softener such as liquid paraffin or paraffin oil from the viewpoint of having good affinity with thermoplastic elastomers such as styrene-based thermoplastic elastomers and preventing bleeding.

The content of the softened oil with respect to the elastic polymer is not particularly limited and may be appropriately determined depending on the type and content of the elastic polymer and the water-absorbent resin described above in addition to the required softness. Considering the degree of elastic deformation and flexibility of the elastic polymer as a molded body, the amount of softened oil is preferably 300 to 1100 parts by mass, and 500 to 900 parts by mass with respect to 100 parts by mass of the elastic polymer. Is particularly preferred.

First, an appropriate amount of water is poured into the insertion portion 21 of the inner layer 2 from the insertion port S of the ejaculation accelerator 1 (common to the inner layer 2 and the outer layer 3). By pouring water into the insertion portion 21 of the inner layer 2, the surface of the insertion portion 21 becomes gelled, causing an appropriate slip on the surface of the insertion portion 21.

Next, a penis (not shown) is inserted from the insertion port S into the insertion portion 21. It is preferable to insert the penis in a state where it is erected to some extent for use. After inserting the penis from the insertion port S into the insertion portion 21 formed in the inner layer 2 whose surface is slippery due to contact with water or the like, the user grasps the ejaculation promoter 1 and preferably in the longitudinal direction of the penis. By moving it up and down moderately along the line, the penis will be stimulated by the stimulating portion X formed inside the insertion portion 21 of the ejaculation promoter 1.

In addition, a void 25 is formed on the outer surface of the inner layer 2 constituting the ejaculation accelerator 1, and the protrusion 31 is inserted into the void 25 from the inner surface of the outer layer 3. The protrusion 31 (tip) can also stimulate the inserted penis in the same manner as the stimulation portion X. In the present embodiment, since there is a certain amount of space due to the gap 25 around the protrusion 31 that has entered the gap of the inner layer 2 and the protrusion 31, the feel of the space of the gap 25 that is not dense as a whole is included. A stimulus other than the stimulating portion X is also applied, and the stimulus varies, and the ejaculation accelerator 1 has a high usability.

Further, when the user grasps the ejaculation promoter 1, the penis is pressed from the inner layer 2 through the outer layer 3 formed so as to cover the surroundings, and a feeling of tightening is transmitted. After the user ejaculates by such an operation, a desired amount of sperm (semen) is collected from the insertion port S, and sperm (semen) remaining in the insertion portion 21 or the like which is the internal space of the inner layer 2 is collected. Try to wash. The above-mentioned sperm (semen) may be collected by inserting a dropper or the like into the insertion port S and sucking the sperm.

The ejaculation accelerator 1 according to the present invention described above has at least a two-layer structure in which the outer layer 3 is formed so as to cover the periphery of the inner layer 2 in which the insertion portion 21 into which the user's penis is inserted is formed, and the outer layer 3 is formed. However, since the inner layer 2 is configured to be visible from the outside, the design of the inner layer 2 can be easily seen from the outside, and the ejaculation accelerator 1 having excellent designability including devising the shape of the inner layer 2 is obtained. .. Further, since the void 25 is formed on the outer surface of the inner layer 2, the void 25 forms a patterned design on the inner layer 2, and the inner layer 2 having a design is the outer layer together with the design of the appearance shape of the inner layer 2. It is an ejaculation accelerator 1 that can be visually recognized from 3 and has excellent design in this respect. In addition, by forming a space due to the gap 25 on the inner wall of the insertion portion 21, the protrusion 31 formed on the inner surface of the outer layer 3 is allowed to enter the gap 25, and other members are inserted into the space. By changing the nuance of the stimulus, it is possible to give a variation to the usability.

The ratio of the area of the void (total) to the area of the outer surface of the inner layer was set to about 44% of the total area of the outer surface of the inner layer. Further, an ejaculation accelerator having the same shape as that of Example 1 and the like and not adding powdered sodium polyacrylate (highly water-absorbent resin) as a constituent material of the inner layer was also manufactured as Reference Example 1.

(Manufacturing method of ejaculation accelerator)
(1) Manufacture of inner layer:
First, as shown in FIG. 15, the core mold shown in FIG. 14 was attached to the inside of one inner frame mold, which is a split mold, and closed by the other inner frame mold. From the side where the material injection port is formed, the resin material for forming the inner layer, which is in a molten state, is injected, and after the material is cooled and solidified, the split mold (inner frame mold) is opened. As shown in FIG. 16, a core mold having an inner layer formed around it was taken out.

As shown in Table 1, the resin material for forming the inner layer is a thermoplastic elastomer (hydrogenated (hydrogenated) styrene-based thermoplastic elastomer (SEBS)) which is an elastic polymer (“elastomer” in Table 1”. The same applies to the outer layer below.) The content of powdered sodium polyacrylate (water-absorbent resin) (described as “Na polyacrylate” in Table 1) with respect to 100 parts by mass is shown in Table 1. The material has the structure shown in the above, and no water-absorbent resin was added to Reference Example 1.

(2) Manufacture of outer layer:
The core mold having an inner layer formed around it obtained in (1) was not removed from the core mold as it was, but was attached to the inside of one of the split molds as shown in FIG. A resin material (thermoplastic elastomer (SEBS), which is an elastic polymer) is used to form the outer layer, which is in a molten state from the side where the material injection port is formed in the state of being closed by the other outer frame type which is a split type. After injecting to cool and solidify such material, the outer frame mold was opened to obtain a molded body in which a transparent outer layer was formed around the inner layer as shown in FIG.

[Appearance of ejaculation accelerator and degree of elasticity]
No colorant was added to the constituent material of the outer layer constituting the ejaculation accelerator so that it became transparent. As a result, the appearance of the ejaculation promoters of Examples 1 to 8 (and Reference Example 1) can be visually recognized from the outside, including the diamond-shaped voids, as shown in FIG. 1 and the like. It was confirmed that it is an ejaculation promoter with excellent design. As for the degree of elastic deformation, it was recognized that the ejaculation promoters of Examples 1 to 8 (and Reference Example 1) were free to elastically deform including the inner layer and the outer layer.

[Test Example 1]
(Evaluation of slip)
An appropriate amount of water was brought into contact with the portion including the insertion portion inside the inner layer from the insertion port of the obtained ejaculation promoters of Examples 1 to 8 and Reference Example 1. Then, the slip of the ejaculation promoter was compared and evaluated using the following evaluation criteria.

The test was evaluated on a 5-point scale, with 5 to 2 passing (5 is the best, hereinafter in the order of 4 → 2), and 1 being rejected. The results are shown in Table 2.

(Evaluation criteria)
Evaluation content 5: The surface of the insertion part is optimally gelled and slippery, and no separate lotion is required 4: The surface of the insertion part is moderately gelled and slippery, and the lotion is separately Not required 3: The surface of the insertion part is gelled, but there is a little slipperiness (no separate lotion is required).
2: The surface of the insertion part becomes gel-like, but there is little slipperiness (no separate lotion is required).
1: The surface of the insertion part does not gel and there is no slipperiness (it is considered that a separate lotion is required).

(result)

As shown in Table 2, in Examples 1 to 8 in which sodium polyacrylate was contained in a thermoplastic elastomer as a constituent material of the inner layer of the ejaculation accelerator, slipperiness was generated, and in particular. , Example 3 to Example 6 were excellent.

As for the feeling of use, according to the result of the above-mentioned slip, those of Examples 1 to 8 are good, and Examples 3 to 6 are the best, and the following, Example 2> Example 7, Example. 8> The order of Example 1 was good. On the other hand, Reference Example 1 which was not slippery had a poor usability as it was, and required a separate lotion.

In addition, as a feeling of use, since a gap is formed in the inner layer and protrusions from the inner surface of the outer layer enter the space, the stimulation portion and protrusions formed in the insertion portion of the inner layer and the space around the protrusions. The nuances of this give the user a variation in usability compared to a structure that simply has a stimulating part. Since Reference Example 1 was a constituent material in which the inner layer and the outer layer were substantially common except for the addition of the colorant, no difference as in Examples 1 to 8 was felt.

The present invention has extremely high industrial applicability because it can be used not only for medical purposes but also for helping to build a healthy society by suppressing sexual impulses of men.
