In III), in order to cause slippage during use, the insertion part 21 (also described later) formed with such a part that stimulates the penis can be used by contacting it with a liquid such as water. showing. Further, as shown in FIGS. 1 to 3 and the like, the ejaculation stimulator 1 according to the present invention is formed to have at least a two-layer structure in which the inner layer 2 is surrounded by the outer layer 3 . The configurations of the inner layer 2 and the outer layer 3 that constitute the ejaculation enhancer 1 will be described below.

(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 voids 25 of the inner layer 2 and the protrusions 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. As shown in FIG. In addition, in FIG. 8, in the inner layer 2, the part corresponding to the void 25 ("." (dot: dot) is the same as in FIG. 1 etc.) and the other part ("." I made it.) to understand the difference. 9 to 11 only show the outer surface of the inner layer 2 as 2a. As shown in FIGS. 1 to 11 (particularly, FIG. 1 and FIG. 10), the inner layer 2 constituting the ejaculation enhancer 1 is elastically deformable and has a tubular shape. An insertion port S is arranged in the body, and an insertion portion 21 is formed as a space extending inwardly from the insertion port S, and a user's penis (not shown) can be inserted through 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 gripped by a user (not shown; the same shall apply hereinafter). The outer layer 3 will be described later), and the inner layer 2 in the present embodiment is also shaped according to the outer layer 3, as shown in FIG. ing.

In the present embodiment, as shown in FIG. 9 and the like, the shape of the inner layer 2 is such that the middle diameter portion 22 is located substantially in the center in the longitudinal direction, and has a middle diameter portion 22 that has a gentle mountain shape in a plan view. Mountain-like large-diameter portions 23 and 24 having a larger diameter are smaller in diameter than the medium-diameter portion 22 and are formed symmetrically with a small-diameter portion 26 serving as a trough sandwiched therebetween.

As shown in FIGS. 5 and 10, in the present embodiment, the ejaculation promoting device 1 has a portion (stimulation portion X) that stimulates the penis on the inner wall of the insertion portion 21 . Examples of the shape of the part that stimulates the penis (stimulation part X) include a convex part (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. FIGS. 5, 6, 7 to 11, etc. show modes in which a bellows shape, a continuous stepped shape, or the like, which is an example of the stimulating portion X, is formed in a predetermined arrangement.

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

The inner layer 2 is preferably colored because it is visible from the outside through the outer layer 3 described later. In order to color the inner layer 2, a coloring agent may be added to the constituent material of the inner layer 2 to color the entire inner layer 2 including the inside, or the outer surface of the inner layer 2 may be colored. Details will be described later.

In the outer surface (wall surface) 2a of the inner layer 2, as shown in FIGS. are formed. In the present embodiment, the space 25 has a rhombic shape (a diamond (◇) shape) in a front view, and the rhomboidal space 25 extends from the outer surface of the inner layer 2 to the insertion portion 21 and penetrates therethrough. Multiple are formed.

In this way, the gaps 25 penetrating the insertion portion 21 are formed in the outer surface 2a of the inner layer 2, so that the gaps 25 form a patterned design in the inner layer 2, which matches the design of the outer shape of the inner layer 2. Therefore, the ejaculation enhancer 1 is excellent in design because the inner layer 2 with such design can be visually recognized from the outer layer. In addition, a space formed by a gap 25 is formed on the inner surface (inner wall) of the insertion portion 21, and another member (in this embodiment, a protrusion formed on the inner surface of the outer layer 3, the tip of which penetrates to the insertion portion 21) is formed in the space. 31), etc. (see FIGS. 7 and 8, etc.) to change the nuances of the stimulus, it is possible to give variation to the feeling of use (you can enjoy various feelings of use), and as a result, The ejaculation stimulator 1 is comfortable to use.

One or more voids 25 may be formed on the outer surface 2a of the inner layer 2 to improve the design and efficiently provide variation in feeling during use. Therefore, it is preferable to form a plurality of them as shown in FIG. 1, etc., FIG. 9, etc. Further, the shape of the void 25 penetrating from the outer surface 2a of the inner layer 2 to reach the insertion portion 21 inside is not limited to the rhombic shape described above, and is triangular, quadrangular (rectangular, (including a square shape, etc.) Any shape such as a polygonal shape such as a pentagonal shape, a circular shape, an elliptical shape, or a geometrical shape can be used. may have a common shape, or may have a plurality of shapes, and furthermore, the area and number that can be confirmed from the outer surface 2a of the inner layer 2, the entire area of the outer surface 2a of the inner layer 2 (including the area of the voids 25, the same applies hereinafter). Considering the strength, etc., the ratio of the area of the voids 25 (total) is preferably set to 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. ), positions, etc. can be determined arbitrarily. Other aspects of the shape of the voids 25 (and the projections 31 formed on the inner surface 3a (see FIG. 12, etc.) of the outer layer 3) will be described later with reference to FIGS. 19 and 20. FIG.

As shown in FIGS. 5 to 8, in the present embodiment, a triangular (Δ , ▽)-shaped projections 51 are shown, which will be described later.

Next, constituent materials and the like of the inner layer 2 will be described. Elastically deformable (Among the deformations that occur when force is applied to an object, the deformation (elastic deformation) that completely returns to its original shape when the force is removed is freely (at will). ), it is preferable to use a material having appropriate elasticity, stretchability, and flexibility, and it is preferable to use an elastic polymer (also called a soft resin). Examples of such elastic polymers include thermoplastic elastomers, elastomers, gel rubbers, silicone resins, polystyrene resins, urethane resins, soft polyvinyl chloride (PVC) resins, and soft polyolefin resins. . One of these elastic polymers may be used alone, or two or more thereof may be used in combination.

As the elastic polymer, it is preferable to use a thermoplastic elastomer, including the outer layer 3 to be described later, in terms of moldability, cost, and feeling of use when used as a molded product. Examples of thermoplastic elastomers include styrene-isoprene-styrene block copolymer (SIS), styrene-butadiene-styrene block copolymer (SBS), (hydrogenated) styrene-ethylene-propylene block copolymer (SEP). , (hydrogenated) styrene-ethylene-butylene-styrene block copolymer (SEBS), (hydrogenated) styrene-ethylene-propylene styrene block copolymer (SEPS), (hydrogenated) styrene ethylene ethylene propylene styrene block copolymer coalesced (SEEPS), styrene-butadiene block copolymer (SBR), (hydrogenated) styrene-butadiene block copolymer (SEB) styrene-isoprene block copolymer (SIR), hydrogenated styrene-isoprene block copolymer (SEP), styrene-isoprene-styrene block copolymer (SIS) and the like are particularly preferred. These may be used individually by 1 type, and may be used in combination of 2 or more type.

Also, for example, natural rubber, polybutadiene, polyisoprene, polyisobutylene, neoprene, polysulfide rubber, thiocol rubber, acrylic rubber, urethane rubber, silicone rubber, epichlorohydrin rubber, ethylene propylene rubber (EPR), ethylene propylene diene rubber (EPDM) , butadiene-acrylonitrile-styrene-core-shell rubber (ABS), methyl methacrylate-butadiene-styrene-core-shell rubber (MBS), methyl methacrylate-butyl acrylate-styrene-core-shell rubber (MAS), octyl acrylate-butadiene-styrene-core-shell rubber ( MABS), alkyl acrylate-butadiene-acrylonitrile-styrene core-shell rubber (AABS), butadiene-styrene-core-shell rubber (SBR), siloxane-containing core-shell rubbers such as methyl methacrylate-butyl acrylate-siloxane, etc. Alternatively, rubbers obtained by modifying these can be mentioned. These may be used individually by 1 type, and may be used in combination of 2 or more type.

In addition, in the present invention, it is preferable that the inner layer 2 contains a water-absorbing resin (also called a water-absorbing polymer or a water-absorbing polymer) in addition to the elastic polymer described above. By using a combination of an elastic polymer and a water-absorbing resin as a constituent material of the inner layer 2, it is possible to disperse in the elastic polymer that becomes the base material when the inner layer 2 is molded, and to impart water absorbency to the inner layer 2. 2 is brought into contact with a liquid such as water (hereinafter, sometimes simply referred to as "water or the like") to gel the surface of the insertion portion 21, thereby allowing the surface of the insertion portion 21 to slide. In addition, since such a moderate slippage is common to pouring lotion into the insertion portion 21, the use of lotion can be reduced as much as possible, preferably the lotion can be eliminated.

The water-absorbing resin is not particularly limited, but examples include polyacrylic acid salts (including crosslinked polyacrylic acid salts), polyacrylamide, starch-acrylonitrile graft copolymer hydrolyzate, carboxymethyl cellulose. Examples include crosslinked products, acrylic acid (salt)-vinyl alcohol copolymers, polyoxyethylene crosslinked products, and thermoplastic resins containing polyalkylene oxide units.

In general, an acrylic acid polymer has a large number of carboxyl groups and is therefore highly hydrophilic, and the water-absorbing resin preferably contains a polyacrylic acid-based salt. In addition, if necessary, the network structure is crosslinked to form a sodium salt, which results in a highly water-absorbent gel and exhibits excellent properties, so that sodium polyacrylate is particularly preferred. A crosslinked sodium polyacrylate (crosslinked sodium polyacrylate) may be used as the sodium polyacrylate. Sodium polyacrylate is also known as a superabsorbent resin (superabsorbent polymer), and is suitable for the purpose of the present invention because it can absorb a large amount of water when added in a small amount.

The water-absorbent resin may be liquid or powdery (including powdery and granular), and preferably powdery. By making it powdery, the surface area is increased, the water absorption capacity is further improved, and the composition is well dispersed in the elastic polymer that is the base material. Although the average particle diameter is not particularly limited, it is preferably, for example, 1 to 1000 μm, and known shapes such as spherical, plate-like, fluid-forming, and irregular shapes can be used.

The content of the water-absorbing resin relative to the elastic polymer as the constituent material of the inner layer 2 can be appropriately determined depending on the type of elastic polymer used, the type of water-absorbing resin, the required properties (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. It is more preferable to contain 100 parts by mass. If the content of the water-absorbing resin is less than 1 part by mass with respect to 100 parts by mass of the elastic polymer, slippage may not occur even when water or the like is brought into contact with the resin. It may exceed the elastic deformation, and may cause a slight increase in cost.

By increasing the content of the water-absorbent resin, the cost of the water-absorbent resin is slightly increased, but there is an advantage that the number of times of gelation can be increased and the number of times of use can be increased. The content of the water-absorbent resin in the elastic polymer is more preferably 5 to 100 parts by mass with respect to 100 parts by mass of the elastic polymer. It is even more preferably 5 to 20 parts by mass, particularly preferably 8 to 20 parts by mass, based on 100 parts by mass.

In the ejaculation enhancer 1 of the present invention, the inner layer 2 is preferably colored in order to make the shape of the inner layer 2 easily visible from the outside. A conventionally known coloring agent may be added to the constituent materials, and the outer surface of the inner layer 2 (see the outer surface 2a in FIG. 9, etc.) 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 coloring agent to the constituent material of the inner layer 2 when coloring the inner layer 2 .

Further, a foaming agent may be added to the constituent materials described above. By adding a foaming agent, the softness and elasticity of the inner layer 2 can be moderated, making it close to human skin. As the foaming agent, conventionally known ones can be used. For example, chemical foaming agents such as inorganic thermal decomposition chemical foaming agents and organic thermal decomposition chemical foaming agents, physical foaming agents, etc. are used. be able to. The same applies to the outer layer 3, which will be described later, regarding the effectiveness of the 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 desired degree of foaming, softness, and the like. The amount is preferably parts by mass, and particularly preferably 0.1 to 10 parts by mass.

(2) Configuration of outer layer 3:
12 is a front view showing the internal structure of the outer layer 3 (only the outer layer 3), and FIG. 13 is a perspective view showing the internal structure of the outer layer 3 (only the outer layer 3) (FIGS. 12 and 13 only). , the inner surface of the outer layer 3 is indicated as 3a). As also shown in FIG. 1 and the like, the outer layer 3 constituting the ejaculation promoting device 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 the inner layer 2 and the outer layer 3 are both elastically deformable, the ejaculation enhancer 1 formed from them is also elastically deformable). 2, and the inner surface 3a of the outer layer 3 has a triangular (Δ, ▽) shape (or quadrangular shape in some places when viewed from the front (also in cross section). The same applies to the protrusions 31.) are formed at positions corresponding to the voids 25 of the inner layer 2 . As shown in FIGS. 5 to 8 (especially see FIGS. 7 and 8), the protrusions 31 are diamond-shaped ( As described above, it is inside the diamond (⋄)-shaped void 25 . As shown in FIGS. 5 to 8 (see FIGS. 7 and 8 in particular), in the present embodiment, the tips of the projections 31 appear (protrude) from the insertion portion 21 of the inner layer 2. showing.

Specifically, in the present embodiment, one of the diamond-shaped (diamond (◇)-shaped) voids 25 formed on the outer surface 2a of the inner layer 2 is formed on the inner surface 3a of the outer layer 3 in a front view (cross-section ) shows a mode in which triangular (Δ) and triangular (▽) projections 31 (the latter is also called an inverted triangle) are combined one by one and are inserted into the inside thereof.

The outer surface (wall surface) 2a of the inner layer 2 in which the voids 25 are formed is in contact with the inner surface 3a of the outer layer 3, and the voids 25 formed in the outer surface 2a of the inner layer 2 are formed on the inner surface 3a of the outer layer 3. The protrusions 31 are inserted. In addition, as shown in FIGS. 5 to 8 (especially refer to FIGS. 7 and 8), the tip of the projection 31 appears in the insertion portion 21 of the inner layer 2, but the insertion portion 21 side of the inner layer 2 is exposed. When viewed from the top, the tip of the protrusion 31 is exposed, so that it becomes 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 enhancer 1 of the present embodiment, the projection 31 or the tip of the projection 31 that enters the insertion portion 21 of the inner layer 2 from the outer layer 3 is similar to the stimulation portion X formed in the insertion portion 21 of the inner layer 2. A penis (not shown) inserted into the portion 21 can be stimulated, and variations in the feeling of use can be imparted. The protrusions 31 formed on the inner surface 3a of the outer layer 3 are not limited to the triangular shape described above, and may have a square shape (including a rectangular shape, a square shape, a diamond shape, etc.), a pentagonal shape, etc. when viewed from the front (cross-sectional view). It can be of any shape, such as polygonal, circular, elliptical, or geometric. Further, when a plurality of protrusions 31 are formed, they may have a common shape overall, or may have a plurality of types of shapes, and the area, number, proportion of the entire outer layer 3, position, etc. are all determined arbitrarily. be able to.

As shown in FIGS. 5 to 8, it is preferable that the tip of the projection 31 formed on the inner surface 3a of the outer layer 3 reaches the insertion portion 21 of the inner layer 2. Even so, when the user grips the ejaculation promoting device 1 during use, the tip of the projection 31 may or may not touch the penis (not shown) inserted into the insertion portion 2, resulting in a gap. Including the presence of 26 , there is more variation in the feeling of use, so there is no problem even if the tip of the protrusion 31 does not reach the insertion portion 21 of the inner layer 2 .

According to the present invention, the outer layer 3 allows the covering inner layer 2 to be visible from the outside. Since the outer layer 3 is formed in such a manner, the shape of the inner layer 2 having the voids 25 formed on the outer surface can be visually recognized from the outside, and the ejaculation enhancer 1 is excellent in design. The outer layer 3 can be of any color such as transparent (clear), translucent, or cloudy as long as the covering inner layer 2 can be visually recognized from the outside. It is preferable to be transparent because addition and steps can be reduced.

The outer layer 3 has an insertion opening S in common with the inner layer 2 and has a tubular shape that can be gripped by a user's hand (not shown). In this 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. With the diameter portion 32 in the middle, mountain-shaped large diameter portions 33 and 34 having a diameter larger than that of the medium diameter portion 32 are formed symmetrically with a small diameter portion 36 having a diameter smaller than that of the medium diameter portion 32 sandwiching a valley. It is Since the user can hold the small-diameter portion 36 or the like, which is a valley, by putting his or her fingers on the handle, the shape is easy for the user to hold.

Among the materials constituting the inner layer 2, it is preferable to use an elastic polymer as a main component for the material constituting the outer layer 3, which can be grasped by 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. , description is omitted. Even if the inner layer 2 contains a water-absorbing resin as the ejaculation enhancer 1, the insertion part 21 into which the penis is inserted is formed with at least a two-layer structure of the inner layer 2 and the outer layer 3. Since it is the inner layer 2 , it is not necessary to positively add the water absorbent resin to the outer layer 3 .

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

As the softening oil, conventionally known softening oils capable of softening thermoplastic elastomers and the like can be used. system softener”), naphthenic oils (naphthenic softeners), aromatic oils (aromatic softeners), and the like can be used. Among these, paraffin-based softeners such as liquid paraffin and paraffin oil are preferably used from the viewpoint of good compatibility with thermoplastic elastomers such as styrene-based thermoplastic elastomers and less bleeding.

The content of the softening oil relative to the elastic polymer is not particularly limited, and may be appropriately determined depending on the type and content of the elastic polymer and water-absorbent resin described above, in addition to the required softness.

After injecting the material and cooling and solidifying the material, the inner mold 6 is opened. The molding temperature may be appropriately determined depending on the resin material to be used, etc., and is preferably 130 to 190° C., particularly preferably 160 to 180° C. Similarly.).

(iii) Step of taking out the core mold 5 around which the shape of the inner layer 2 is formed from the inner frame mold 6:
When the inner frame mold 6 is opened, as shown in FIG. 16, the core mold 5 around which the inner layer 2 is formed appears. FIG. 16 is a diagram showing a state in which the inner layer 2 is formed around the core mold 5. As shown in FIG. The resin material for forming the inner layer 2 covers the insertion section forming section 51 in a mold-clamped state, forms the insertion section 21 and the like therein, and forms the stimulation section X in the insertion section 21. go. Further, the insertion port forming portion 54 forms an insertion port S, which is a hole connected to the insertion portion 21 and the like.

On the other hand, due to the presence of the gap forming portion 52 of the core die 5, a gap 25 communicating with the insertion portion 21 is formed on the outer surface. In the inner frame mold 6, the inside to which the core mold 5 is attached is hollowed out so as to exhibit the outer shape of the inner layer 2, so that the resin material enters between the plurality of gap forming portions 52 around the core mold 5. By cooling and solidifying, the shape of the inner layer 2 shown in FIG. 9 and the like is formed.

(III) Usage of Ejaculation Promoter 1:
An example of how to use the ejaculation enhancer 1 according to this embodiment will be described below. In addition, in this column, the inner layer 2 is formed of a material containing an appropriate amount of water-absorbent resin in the elastic polymer as a constituent material of the inner layer 2 (for example, Examples 1 to 8 described later (preferably , Embodiments 3 to 6), etc.). First, an appropriate amount of water is poured into the insertion portion 21 of the inner layer 2 from the insertion port S (common to the inner layer 2 and the outer layer 3) of the ejaculation enhancer 1 . By pouring water into the inserting portion 21 of the inner layer 2, the surface of the inserting portion 21 is gelled, and the surface of the inserting portion 21 is caused to slide appropriately.

Next, a penis (not shown) is inserted through the insertion opening S into the insertion portion 21 . It is preferable for use that the penis is inserted in a somewhat erect state. After inserting the penis from the insertion opening S into the insertion portion 21 formed in the inner layer 2, the surface of which is slippery due to contact with water or the like, the user grips the ejaculation enhancer 1, preferably in the longitudinal direction of the penis. The penis is stimulated by the stimulation part X formed inside the insertion part 21 of the ejaculation promoting device 1 by moderately moving it up and down along.

In addition, the inner layer 2 constituting the ejaculation promoting device 1 has a gap 25 formed on the outer surface, and a projection 31 enters the gap 25 from the inner surface of the outer layer 3 . Such protrusions 31 (the tips thereof) can also stimulate the inserted penis in the same manner as the stimulating portion X. In the present embodiment, since there is a certain amount of space due to the gaps 25 around the projections 31 that have entered the voids of the inner layer 2, there is a sense of feeling due to the spaces in the voids 25 that are not dense as a whole. Stimulations other than the stimulating part X are also given, the stimulations are varied, and the ejaculation promoting device 1 has a high feeling of use.

In addition, when the user grips the ejaculation promoting device 1, the penis is pressed from the inner layer 2 through the outer layer 3 formed so as to cover the surroundings, and a tightening feeling 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 removed. make sure to wash. The sperm (semen) may be collected by inserting a dropper or the like into the insertion port S and sucking the sperm.

In the method of use described above, an appropriate amount of water-absorbing resin is added to the elastic polymer as the constituent material of the inner layer 2, and the insertion portion 21 of the inner layer 2 is brought into contact with a liquid such as water so that the surface of the insertion portion 21 is However, the method of using the ejaculation enhancer 1 is not limited to this. That is, even when the inner layer 2 does not contain a water-absorbing resin as a constituent material, there is no problem even if the inner layer 2 is coated with lotion or the like to cause slippage.

(IV) Effects of the present invention:
The ejaculation enhancer 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 inner layer 2 formed with the insertion portion 21 into which the user's penis is inserted. 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 enhancer 1 is excellent in design including devising the shape of the inner layer 2. . In addition, since the voids 25 are formed on the outer surface of the inner layer 2, the voids 25 form a patterned design in the inner layer 2, and together with the design of the outer shape of the inner layer 2, the inner layer 2 with designability is the outer layer. The ejaculation enhancer 1 can be visually recognized from 3 and is excellent in design in this respect as well. In addition, since a space is formed by 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 inserted into the gap 25, or other members are inserted into the space. By changing the nuance of stimulation, it is possible to give variation to the feeling of use.

(V) Modification of Embodiment:
It should be noted that the aspect described above shows one aspect of the present invention, and the present invention is not limited to the above-described embodiments, and can achieve the object and effect by having the configuration of the present invention. It goes without saying that modifications and improvements within the scope are included in the content of the present invention. In addition, the specific structure, shape, etc. in carrying out the present invention may be changed to other structures, shapes, etc. within the scope of achieving the object and effect of the present invention. The present invention is not limited to the above-described embodiments, and includes modifications and improvements within the scope of achieving the object of the present invention.

For example, in the above-described embodiment, a plurality of diamond-shaped voids 25 are formed in the outer surface 2a of the inner layer 2 (see FIG. 10, etc.), but the shape of the voids 25 is arbitrary. The ejaculation enhancer 1 may have a gap 25 having a shape as shown in 18 or 19 .
19 and 20 are perspective views showing other aspects of the ejaculation enhancer 1 according to the present invention. The same reference numerals are given to the same structures and the same members as those of the embodiment described above, and the detailed description thereof will be omitted or simplified.

In the configuration shown in FIG. 19, relatively large diamond shapes and small round shapes (or elliptical shapes) are connected in series along the longitudinal direction on the outer surface of the inner layer 2 to form gaps 25. 25 shows a mode in which a block-shaped projection 31 having an uneven tip (not shown) formed on the inner surface of the outer layer 3 enters.

Moreover, FIG. 20 shows a plurality of rod-shaped slits formed on the inner surface of the outer layer 3 in the gap 25 along a spiral slit that is a gap 25 formed on the outer surface of the inner layer 2 with a predetermined width. The protrusion 31 and the plate-shaped protrusion 31 are shown as a series and entering.
The ejaculation enhancer 1 of the mode shown in FIGS. 19 and 20 also preferably exhibits the effects described in (IV) above.

In the above-described embodiment, the voids 25 are formed on the outer surface of the inner layer 2, and the protrusions 31 formed on the inner surface of the outer layer 3 enter the voids 25. However, the formation of the protrusions 31 (and the voids 25 entering) is not essential, and even if nothing exists inside the void 25 of the inner layer 2, the difference in the structure of the space formed by the void 25 and the surrounding stimulating part X provides variations in the feeling of use. be able to. Even when the projections 31 are formed by the outer layer 3, by devising the clearance between the gaps 25 and the projections 31, further variation and uniqueness of the feeling of use can be given, and as a result, the feeling of use is also good. Become.

In the embodiment described above, the shapes of the inner layer 2 and the outer layer 3, which are both elastically deformable, have been described using the shapes shown in FIG. 1 and the like. On the other hand, the shape of the inner layer 2 and the outer layer 3 is not limited to this. The shape and the like can be arbitrarily determined as long as it covers the periphery of the inner layer 2 . Similarly, if the inner layer 2 is also a cylindrical member having an insertion opening S on at least one end face in the longitudinal direction and an insertion portion 21 forming a space extending inward from the insertion opening S, for example, The shape, etc., such as a cylindrical shape, can be arbitrarily determined.

Further, regarding the shape of the insertion portion of the inner layer 2, etc., in the above-described embodiment, an example of the shape of the portion that stimulates the penis (stimulation portion X) formed on the inner wall of the insertion portion 21 of the inner layer 2 is a bellows shape. 5, 9, etc., but the shape of the stimulating portion X may be other than those described above, and may be a conventionally known shape that has the potential to stimulate the penis. can be adopted.

In the above-described embodiment, the inner layer 2 and the outer layer 3 constituting the ejaculation enhancer 1 are provided with an insertion opening S at one end face in the longitudinal direction, and an insertion portion 21 is formed as a space extending inward from the insertion opening S. Although an embodiment in which the outer layer 3 is formed so as to cover the inner layer 2 that has been formed has been described as an example, for example, the insertion portion 21 is penetrated through the inner layer 2, and two insertion openings S (not shown) including the outer layer 3 are formed. , the insertion opening S may be connected by the insertion portion 21 .
In addition, the specific structure, shape, and the like in carrying out the present invention may be other structures and the like as long as the object of the present invention can be achieved.

EXAMPLES The present invention will be described in more detail below based on Examples and Reference Examples, but the present invention is not limited to these.

[Examples 1 to 8, Reference Example 1]
In accordance with (i) to (vii) described in "(II) Manufacturing method of ejaculation enhancer 1:", the following manufacturing method is used to produce an ejaculation enhancer ( Examples 1 to 8) were produced. The ratio of the area of the voids (total) to the area of the outer surface of the inner layer was about 44% of the total area of the outer surface of the inner layer. In addition, an ejaculation enhancer having the same shape as that of Example 1 and the like, but without addition of powdered sodium polyacrylate (superabsorbent resin) as a constituent material of the inner layer was also manufactured as Reference Example 1.

(Manufacturing method of ejaculation enhancer)
(1) Manufacture of inner layer:
First, as shown in FIG. 15, the core mold shown in FIG. 14 was attached inside one of the split molds, the inner frame mold, and closed with the other inner frame mold. A molten resin material for forming the inner layer is injected from the side where the material injection port is formed, and after the material is cooled and solidified, the split mold (inner frame mold) is opened, A core mold around which an inner layer was formed as shown in FIG. 16 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)) that is an elastic polymer ("elastomer" in Table 1). The same applies to the outer layer below.) The content of powdery sodium polyacrylate (water absorbent resin) (described as “Na polyacrylate” in Table 1) is shown in Table 1 for 100 parts by mass. , and the water-absorbing resin was not added to Reference Example 1.

(2) Manufacture of the outer layer:
The core mold with the inner layer formed around it obtained in (1) was attached to the inside of one of the outer frame molds, which were split molds, as shown in FIG. 17 without removing the inner layer from the core mold. While closed by the other outer frame mold, which is a split mold, a resin material (thermoplastic elastomer (SEBS), which is an elastic polymer) for forming the outer layer, which is in a molten state, is poured from the side where the material injection port is formed. After injecting and cooling and solidifying the material, the outer frame mold was opened to obtain a compact having a transparent outer layer formed around the inner layer as shown in FIG.

(3) Manufacture of ejaculation enhancer:
Then, the molded body having the colored inner layer and the transparent outer layer that allows the inner layer to be visually recognized is removed from the core mold, and the two layers formed so that the outer layer covers the inner layer as shown in FIG. A structural ejaculation stimulator was obtained.

A softening oil (liquid paraffin) was added to the constituent materials of the inner and outer layers (the softening oil was 800 parts by mass with respect to 100 parts by mass of the elastic polymer (thermoplastic elastomer)), and the molding temperature was 160 to 160 parts. Each structure was appropriately adjusted and molded at 180°C. As for the constituent material of the inner layer, 0.38 parts by mass of a coloring agent (white) was added to 100 parts by mass of the elastic polymer (thermoplastic elastomer) to color the inner layer white. Table 1 shows the constituent materials of the ejaculation enhancer.

(Constituent material of ejaculation enhancer)

[Appearance and Elasticity of Ejaculation Promoter]
No coloring agent was added to the constituent material of the outer layer of the ejaculation enhancer, so that the outer layer was transparent. As a result, the appearance of the ejaculation enhancers of Examples 1 to 8 (and Reference Example 1) was such that the shape of the inner layer, including the rhomboidal voids, could be visually recognized from the outside, as shown in FIG. , it was confirmed that the ejaculation enhancer has an excellent design. As for the degree of elastic deformation, it was confirmed that the ejaculation enhancers of Examples 1 to 8 (and Reference Example 1) were elastically deformable including the inner and outer layers.

[Test Example 1]
(Slip evaluation)
An appropriate amount of water was brought into contact with the inner layer including the insertion portion through the insertion port of the obtained ejaculation enhancers of Examples 1 to 8 and Reference Example 1. Then, the slippage of the ejaculation stimulator was compared and evaluated using the following evaluation criteria.

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

(Evaluation criteria)
Evaluation details 5: The surface of the insertion site, etc. is optimally gelled, and it is very slippery, and no separate lotion is required. Unnecessary 3: The surface of the insertion site turns into a gel, but it is a little slippery (no separate lotion is required.)
2: The surface of the insertion part turns into a gel, but the slipperiness is slightly less (no separate lotion is required.)
1: The surface of the insertion part, etc. does not gel, and there is no slippery feeling (it is considered that a separate lotion is necessary.)

(result)

As shown in Table 2, in Examples 1 to 8, in which sodium polyacrylate was added to the thermoplastic elastomer as the constituent material of the inner layer of the ejaculation enhancer, slipperiness occurred in all cases. , Examples 3 to 6 were excellent.

The feeling of use is also in accordance with the result of slipping described above, and the products of Examples 1 to 8 are good, and the products of Examples 3 to 6 are the best. 8> were good in the order of Example 1. On the other hand, in Reference Example 1, which did not have a slippery feeling, the feeling of use was not good as it was, and a separate lotion was required.

In addition, as a feeling of use, voids are formed in the inner layer, and projections from the inner surface of the outer layer enter into these spaces, so the stimulating portion and the protrusions formed in the insertion portion of the inner layer, and the space around the protrusions. This nuance gives the user a variety of usability compared to a structure with a simple stimulation part. In Reference Example 1, except for the addition of the colorant, the inner layer and the outer layer were made of substantially the same constituent material, so that the difference was not as great as in Examples 1 to 8.

INDUSTRIAL APPLICABILITY The present invention has extremely high industrial applicability because it can help build a healthy society by suppressing male sexual impulses, as well as medical applications.
