Description

Technical Field

[0001] This invention relates to sperm collection devices, and more particularly to sperm collection devices that have been improved based on the needs of medical research and treatment, and which are improvements on previously used sperm collection devices. Background Technology

[0002] Based on the needs of medical research and treatment, various sperm collection devices (ejaculation facilitators for promoting ejaculation) have been proposed.

[0003] Sperm collection devices are used for medical purposes, such as to examine the husband's sexual function or treat sexual dysfunction based on the collected sperm in order to determine the cause of infertility between couples, and to preserve and store sperm for artificial insemination.

[0004] A sperm collection device is a unit that has an insertion space for penile insertion and stimulates the tip of the penis by friction generated by the penile moving in and out of the insertion space, thereby promoting ejaculation.

[0005] For example, Patent Document 1 discloses an ejaculation facilitator, comprising: a cylindrical container made of rigid plastic material, with an opening at its base in the longitudinal direction and an air hole at its front end; and a core component made of gel-like resin, which is housed within the container and has an insertion space extending inward from the insertion port at the base in the longitudinal direction.

[0006] In the ejaculation facilitator of Patent Document 1, ejaculation is facilitated by stimulating the tip of the penis by moving the penis, which is inserted into the insertion port, back and forth within the insertion space. Furthermore, in this ejaculation facilitator, a decompression device is installed on the front side of the container, and decompression is applied to the container through an air hole, thereby providing strong stimulation to the penis.

[0007] Furthermore, Patent Document 2 discloses a male-female masturbation device comprising: an inner body made of elastic resin, with a penile insertion port at its base along its length and an insertion space connected to the insertion port; a container, which is bottle-shaped with an open base and a closed front end along its length and houses the inner body; and an air volume adjustment ring configured to rotate freely relative to the outer peripheral surface of the container near its base. The masturbation device of Patent Document 2 is further configured to stimulate the tip of the penis by moving the penis inserted through the insertion port back and forth within the insertion space.

[0008] Furthermore, in the masturbation device of Patent Document 2, a container-side opening is provided on the side near the base end in the longitudinal direction within the container, and a ring-side opening is provided on the air volume adjustment ring. The area of ​​the overlapping portion of the container-side opening and the ring-side opening is changed according to the amount of rotation of the air volume adjustment ring. In this masturbation device, the airflow circulating inside and outside the container is adjusted according to the area of ​​the overlapping portion of the two openings, thereby adjusting the intensity of stimulation applied to the penis.

[0012] Patent Document 2: International Publication No. 2015 / 092081 Summary of the Invention

[0013] The problem the invention aims to solve

[0014] In the masturbation device of Patent Document 2, since a container-side opening and a ring-side opening are provided on the outer peripheral surface of the container, the user may inadvertently block the ring-side opening with their finger during use. If the ring-side opening is blocked by a finger on the outer peripheral surface of the container, air circulation is difficult, which may impair the ejaculation-promoting effect due to changes in stimulation beyond the user's control.

[0015] The present invention was made in view of this situation, and its purpose is to suppress changes in stimulation that are not of the user's consent during the use of the sperm collection device.

[0016] means for solving problems

[0017] To address the aforementioned problems, the sperm collection device of the present invention comprises: a core component made of an elastic material, having an insertion port for a penis and an insertion space for relative movement of the penis inserted into the insertion port; and a container having the core component housed in its inner space. The sperm collection device is characterized in that the container comprises: a base unit, which is a cylindrical shape open at both ends axially, with the insertion port end of the core component mounted at one end; and a movable unit, which is a cylindrical shape open at one end axially and closed at the other end, mounted to rotate freely about its axial center relative to the other end of the base unit. One end of the movable unit is configured to overlap with the other end of the base unit, and the overlapping portion of the movable unit and the base unit has an airflow path. An adjustment mechanism is provided on the overlapping portion, the adjustment mechanism adjusting the airflow rate circulating inside and outside the container according to the rotation angle of the movable unit relative to the base unit.

[0064] <Overview and features of sperm collection device 1>

[0065] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0066] First, the general outline and features of the sperm collection device 1 will be described. Figure 1 (a) in the figure is a cross-sectional view of the sperm collection device 1. Figure 1 (b) is a cross-sectional view illustrating the insertion space ES inside the core component 10. Figure 2 This is an attached diagram illustrating the usage of the sperm collection device 1.

[0067] Figure 1 (a) and Figure 1 The sperm collection device 1 shown in (b) comprises: a core component 10 and a container 20. The core component 10 is made of a cylindrical elastic material and is provided with an insertion space ES, which allows the penis P (see reference 11a) to be inserted into the insertion port 11a. Figure 2 The container 20 can move relative to the core component 10; the container 20 has an inner space IS for accommodating the core component 10.

[0068] The core component 10 is made of an elastic material such as an elastomer or gel resin, and its volume changes as the penis P moves relative to the insertion space ES. For example, if the penis P moves from the base to the inner depth within the insertion space ES, the core component 10 expands; if the penis P moves from the inner depth to the base within the insertion space ES, the core component 10 contracts.

[0069] The container 20 includes: a base unit 30 made of rigid plastic material (rigid resin material), configured as a cylinder open at both ends axially, with the end of the core component 10 at the base end (one end side) of the opening mounted thereon; and a movable unit 40 made of rigid plastic material, configured as a cup (cylindrical) open at the base end (one end) and closed at the front end (the other end), and assembled so that it can rotate freely about the axial center relative to the base unit 30 without falling off. The base unit 30 is fixedly or detachably supported near the end (base end) of the core component 10 at the insertion port 11a side.

[0070] At the axial midpoint P1 of the sperm collection device 1, the inner circumferential surface of the base end of the movable unit 40 coincides with the outer circumferential surface of the front end of the base unit 30. An airflow path AP for allowing air to circulate inside and outside the container 20, and an adjustment mechanism AD for adjusting the airflow rate of the airflow path AP, are provided at the overlapping portion of the two opposing circumferential surfaces. The adjustment mechanism AD adjusts the airflow rate of the airflow path AP according to the rotation angle of the movable unit 40 relative to the base unit 30.

[0071] like Figure 2 As shown, during the use of the sperm collection device 1, the penis P (the tip PT) moves back and forth axially within the insertion space ES. Since the penis P is in contact with the inner circumferential surface of the core component 10, it is stimulated by friction (sliding friction) as it moves within the insertion space ES, thus promoting ejaculation.

[0072] Furthermore, during the use of the sperm collection device 1, a viscous liquid lubricant is applied to the insertion space ES as needed, and a contraceptive device (condom, not shown) is installed on the user's penis P. In this case, the user's semen is sprayed into the contraceptive device and collected. Alternatively, semen sprayed into the insertion space ES can also be collected without using lubricant.

[0073] By moving the tip PT of the penis P relative to the inner depth within the insertion space ES from the base side, the core component 10 expands outward due to the penis P within the insertion space ES, as indicated by the dashed line labeled "EX". As a result, air in the inner space IS of the container 20 is exhausted to the outside of the container 20 via the adjustment mechanism AD and the airflow path AP.

[0074] As the anterior end PT of the penis P moves relative to the basal end within the insertion space ES, decompression occurs within the insertion space ES. Accompanying this decompression within the insertion space ES, the core component 10 contracts as indicated by the dashed line labeled "CT".

[0075] As a result, the contact force between the anterior end PT of the penis P and the inner peripheral surface of the core component 10 becomes stronger, thus intensifying the stimulation of the anterior end PT of the penis P. Additionally, as the core component 10 contracts, air outside the container 20 flows into the inner space IS of the container 20 through the airflow path AP and the adjustment mechanism AD.

[0076] like Figure 1 As shown in (a), the adjustment mechanism AD has a structure that allows for flexible modification of the area of ​​the overlapping portion between the rubber ring-side opening 34c (second opening) of the base unit 30 (second rubber ring 34) and the curved plate-side opening 42e (first opening) of the movable unit 40. For example, in the adjustment mechanism AD of the first embodiment, by changing the number of rubber ring-side openings 34c (small holes) arranged in the curved plate-side opening 42e, the area of ​​the overlapping portion between the rubber ring-side opening 34c and the curved plate-side opening 42e is changed, thereby adjusting the airflow (air flowability) in the adjustment mechanism AD.

[0077] The stimulation of the anterior end of the penis P to PT is altered by adjusting the airflow through the adjustment mechanism AD. Furthermore, the adjustment of the airflow using the adjustment mechanism AD will be explained in detail later.

[0078] like Figure 2As shown, when the airflow in the adjustment mechanism AD is low (when airflow is difficult), if the penis P (front end PT) moves relative to the inner depth side from the base side in the insertion space ES, the core component 10 expands, causing air to be discharged from the insertion space ES to the inner space IS of the container 20. Since it becomes more difficult for air to be discharged from the inner space IS of the container 20 to the outside of the container 20, the expansion of the core component 10 becomes more difficult, which makes the stimulation of the penis P by the protrusion 11e stronger.

[0079] Similarly, when the airflow in the adjustment mechanism AD is low, if the penis P moves relative to the base side from the deep side inside the insertion space ES, it becomes more difficult for air to flow from the outside of the container 20 to the inner space IS, making it more difficult for the core component 10 to contract. The increased contact force between the anterior end PT of the penis P and the inner peripheral surface of the core component 10 makes the stimulation of the penis P by the protrusion 11e stronger.

[0080] Conversely, when the airflow in the adjustment mechanism AD is greater (when air flows more easily), if the penis P moves relatively from the base side to the deeper side within the insertion space ES, air flows smoothly from the inner space IS to the outside of the container 20. Therefore, compared to when the airflow is less, the core component 10 expands more easily. As a result, the stimulation of the penis P by the protrusion 11e is weaker compared to when the airflow is less.

[0081] Similarly, when the airflow in the adjustment mechanism AD is greater, if the penis P moves relative to the base side within the insertion space ES, air flows smoothly from outside the container 20 into the inner space IS. Therefore, compared to when the airflow is less, the contraction of the core component 10 becomes easier, and the adhesion between the penis P and the inner peripheral surface of the core component 10 decreases. As a result, the stimulation of the penis P by the protrusion 11e is weaker compared to when the airflow is less.

[0082] Therefore, when the airflow in the adjustment mechanism AD is less than when there is a larger airflow, the stimulation of the anterior end PT of the penis P is greater, thereby promoting ejaculation.

[0083] As will be described later, the airflow (air resistance of the adjustment mechanism AD) flowing inside and outside the container 20 is adjusted according to the rotation angle of the movable unit 40 relative to the base unit 30. The adjustment mechanism AD is separately configured on the base unit 30 side and the movable unit 40 side, and is connected to the outside of the container 20 through the airflow path AP provided along the boundary between the inner peripheral surface of the base end of the movable unit 40 and the outer peripheral surface of the front end of the base unit 30.

[0084] In this sperm collection device 1, the airflow path AP and the adjustment mechanism AD are located at the overlapping part where the base end (one end) of the movable unit 40 and the front end (the other end) of the base unit 30 are opposite each other. Therefore, during use, it is difficult for the user to block the airflow path AP with their fingers, and the user can suppress changes in stimulation that are not in their own interest.

[0085] <Details of the sperm collection device 1 according to the first embodiment>

[0086] The details of the sperm collection device 1 according to the first embodiment will now be described. First, the core component 10 will be described. Figure 3 Figure (a) illustrates the core component 10. Figure 3 (b) in the diagram illustrates the ring component.

[0087] <Core Component 10>

[0088] Figure 2 The sperm collection device 1 shown has a core component 10, which is in close contact with the anterior end PT of the penis P that moves back and forth along the length direction within the insertion space ES, thereby stimulating the penis P.

[0089] like Figure 3 As shown in (a), the core component 10 includes: a core body 11 made of an elastic material (elastomer, gel resin, etc.) that mimics the softness of the human body (inside the vagina); and multiple (e.g., 3) ring components 12 made of an elastic material (elastomer, gel resin, etc.) that is harder than the core body 11 and are enclosed within the core body 11.

[0090] The core body 11 includes: a disc-shaped flange portion 11b, with an insertion port 11a at the center of its end face; a cylindrical portion 11c, with an insertion space ES inside; and a ring-shaped receiving portion 11d, which is provided in multiple (e.g., 3) spaced apart in the portion of the cylindrical portion 11c near the flange portion 11b.

[0091] The flange portion 11b is fixedly or detachably installed relative to the base end 30a of the base unit 30 of the container 20 (the base end 31a of the first cylindrical component 31) in an airtight state.

[0092] The cylindrical portion 11c is a bag-like structure with its front end closed, and an insertion space ES communicating with the insertion port 11a is provided inside. Furthermore, the inner circumferential surface of the cylindrical portion 11c has multiple protrusions 11e, giving it a concave-convex shape. The anterior end PT of the penis P is in close contact with the inner circumferential surface of the cylindrical portion 11c within the insertion space ES. Therefore, if the anterior end PT of the penis P moves relatively forward and backward within the insertion space ES, the anterior end PT is stimulated by the protrusions 11e, thereby promoting ejaculation.

[0093] 11d storage unit Figure 3 The ring component 12 shown in (b) has: an annular outer peripheral portion 12a; a disc-shaped inner peripheral portion 12c, the center of which has an opening 12b for insertion of the penis P; and a plurality of spoke portions 12d that connect the outer peripheral portion 12a and the inner peripheral portion 12c circumferentially.

[0094] Opening 12b forms part of the insertion space ES (see reference) Figure 1 (b) of the diagram. The inner peripheral portion 12c is provided with a plurality of protrusions 12e that are curved into a vortex shape toward the opening portion 12b. These protrusions 12e generate a circumferential rotational force through friction with the penis P during the forward and backward movement of the penis P. The spoke portion 12d is curved circumferentially by this rotational force, causing the inner peripheral portion 12c to rotate and thereby stimulating the penis P.

[0095] <Container 20>

[0096] Next, container 20 will be described. Figure 4 This is the main view of container 20. Figure 5 This is an exploded 3D view of container 20. Figure 6 This is a cross-sectional view of container 20.

[0097] like Figure 4 to Figure 6 As shown, the container 20 includes: a cylindrical base unit 30 configured as a cylinder with open ends in the axial direction; a movable unit 40 configured as a cup (cylindrical) with an open base end in the axial direction and a closed front end, and is assembled to rotate freely about the axial center relative to the front end of the base unit 30 without falling off; and a cover CP, which is installed relative to the base end of the base unit 30 and can be freely attached and detached.

[0098] <Matrix Unit 30>

[0099] like Figure 5 As shown, the base unit 30 includes: a cylindrical first cylindrical member 31, open at both ends; a second cylindrical member 32, which is also open at both ends and has a generally V-shaped recess (V-groove) 32a provided along its entire circumference in the middle of its axial direction; a first rubber ring 33, which is sandwiched between the front end of the first cylindrical member 31 and the base end of the second cylindrical member 32; and a second rubber ring 34, which is installed at the front end of the second cylindrical member 32. Furthermore, by providing the recess 32a, the user's fingertip can easily be caught within the recess 32a, preventing the sperm collection device 1 from falling from the user's hand.

[0100] like Figure 1As shown, a flange 11b of the core component 10 is fixedly or detachably mounted along the entire circumference of the base end 31a of the first cylindrical component 31 in an airtight manner. Compared to the base end of the container 20, the base end of the core component 10 protrudes slightly outward in the axial direction (towards the user during use).

[0101] like Figure 6 As shown, half of the front end side of the first cylindrical component 31 and half of the base end side (the portion of the base end side starting from the recess 32a) of the second cylindrical component 32 are matched with each other, and the outer peripheral surface of the half base end side of the second cylindrical component 32 is fitted into the inner peripheral surface of the half front end side of the first cylindrical component 31 in a close contact state.

[0102] like Figure 5 As shown, the first rubber ring 33 includes: an elongated cylindrical portion 33a; and an annular flange portion 33b, which is configured to protrude laterally from the front end of the cylindrical portion 33a. Figure 6 As shown, the cylindrical portion 33a of the first rubber ring 33 is in close contact with the inner circumferential surface of the first cylindrical component 31, and the flange portion 33b is sandwiched between the first cylindrical component 31 and the second cylindrical component 32. The first cylindrical component 31 and the second cylindrical component 32 are connected in an airtight state because the first rubber ring 33 is sandwiched between them.

[0103] In the sperm collection device 1 of the first embodiment, the first cylindrical component 31 and the second cylindrical component 32 are respectively made of rigid plastic material (for example, the first cylindrical component 31 is polycarbonate resin and the second cylindrical component 32 is ABS resin), and the first rubber ring 33 is made of synthetic resin (various rubber materials or elastomers with rubber elasticity) that has softness and sealing properties.

[0104] like Figure 5 As shown, a slender base-side opening 32c, with a length less than the entire circumference, is provided circumferentially on the side (outer peripheral surface) of the front end portion 32b of the second cylindrical component 32. As described later, a protrusion 34b equipped with a second rubber ring 34 is fitted onto the base-side opening 32c, and the inner space IS of the container 20 and the air flow path AP are connected via the rubber ring-side opening 34c (small hole, second opening) provided on the protrusion 34b (refer to...). Figure 6 ).

[0105] like Figure 4 and Figure 5As shown, a base-side marking 32d is formed on the surface of the V-shaped recess 32a in the second cylindrical component 32, and in the circumferential range corresponding to the base-side opening 32c. Multiple slots (recesses) of different lengths are spaced circumferentially on the base-side marking 32d. The length of the base-side marking 32d (the length of the slot) indicates the airflow adjusted by the adjustment mechanism AD. For example, the shortest leftmost base-side marking 32d indicates the state with the least airflow, and the longest rightmost base-side marking 32d indicates the state with the most airflow. The base-side markings 32d (each slot) extend to the base-side opening 32c, and the inner side of the slot becomes part of the airflow path AP.

[0106] In addition, the air flow path AP can be provided between the outer peripheral surface of the base unit 30 and the inner peripheral surface of the movable unit 40, so the groove that can also be part of the air flow path AP can be provided on the inner peripheral surface of the base end of the movable unit 40 (cup component 41).

[0107] like Figure 5 and Figure 6 As shown, a circumferentially extending locking groove 32e is provided at the front edge of the V-shaped recess 32a in the second cylindrical component 32 (the boundary with the base-side opening 32c). Through the locking groove 32e, the movable unit 40 is locked so that it can rotate freely about the axis center relative to the base unit 30 and cannot fall off (as described below).

[0108] Furthermore, one of the second cylindrical component 32 and the movable ring 42 may be made of a rigid plastic material with elastic properties, while the other may be made of a rigid plastic material without elastic properties. A locking structure consisting of a combination of protrusions and recesses may also be provided on the second cylindrical component 32 and the movable ring 42. For example... Figure 5 As shown in one example, an elastic piece 32f with a protrusion formed on its inner circumference is provided at the front end of the second cylindrical component 32. The protrusion of the elastic piece 32f is engaged with the engaging recess 42d of the movable unit 40. Therefore, in Figure 5 In the example, the elastic sheet 32f and the engaging recess 42d constitute the engaging structure.

[0109] Multiple protrusions 32g are circumferentially spaced along the front periphery of the second cylindrical component 32. For example... Figure 8 As shown, the front end of each tab 32g abuts against the flange portion 42a from the axial base end side, supporting the movable ring 42.

[0110] like Figure 5 and Figure 6As shown, the second rubber ring 34 has an elongated cylindrical portion 34a, which is in close contact with the inner circumferential surface of the front end portion 32b of the second cylindrical component 32. The portion corresponding to the base-side opening 32c in the second rubber ring 34 (the portion within the opening range) is thicker than other portions, and an elongated protrusion 34b is formed circumferentially. The rubber ring-side opening 34c is provided on the protrusion 34b, and the protrusion 34b is fitted into the base-side opening 32c.

[0111] The opening 34c on the rubber ring side is, for example, a small circular hole, and multiple such holes are formed at circumferential intervals. Figure 5 As shown, in the first embodiment, nine rubber ring-side openings 34c are provided. The first to seventh rubber ring-side openings 34c from the left end have the same shape (same opening area). In addition, the eighth and ninth rubber ring-side openings 34c from the left end have the same shape (same opening area) and are larger than the first to seventh rubber ring-side openings 34c.

[0112] In addition, the openings 34c on each rubber ring side can also be composed of multiple circular holes of equal size, or they can be composed of holes of shapes other than circles, such as quadrilaterals.

[0113] In the sperm collection device 1 of the first embodiment, the second rubber ring 34 is made of a synthetic resin (e.g., various rubber materials or elastomers with rubber elasticity) having the same softness and sealing properties as the first rubber ring 33.

[0114] <Movable Unit 40>

[0115] Next, the movable unit 40 will be explained. Figure 7 This is a perspective view of the cup component 41 as seen from the opening side (base end side). Figure 8 This is a perspective view illustrating the installation state of the movable ring 42 in the base unit 30.

[0116] like Figure 5 As shown, the movable unit 40 includes: a cup-shaped cup member 41, with its base end (one end) open and its front end (the other end) closed, and the diameter of the front end is smaller than that of the base end; and a movable ring 42, which is mounted on the inner circumferential surface of the cup member 41 at the base end opening side and rotates integrally with the cup member 41. In this embodiment, the cup member 41 is made of a rigid plastic material (e.g., polycarbonate resin). Moreover, by making the cup member 41 from a different type of resin material than the second cylindrical member 32, the generation of abnormal noise caused by sliding friction is suppressed, and the cup member 41 and the second cylindrical member 32 can slide smoothly.

[0117] like Figure 4As shown, a movable side mark 41a is provided on the outer peripheral surface of the base end of the cup component 41. The movable side mark 41a is composed of protrusions, and its circumferential position is matched to one of a plurality of base side marks 32d according to the rotation angle of the movable unit 40 relative to the base unit 30. In addition, the movable side mark 41a can also be formed by printing or sticker.

[0118] As described above, the length of the base-side mark 32d (the length of the groove) indicates the airflow (air resistance) in the adjustment mechanism AD. Therefore, the user can identify the airflow based on the length of the base-side mark 32d indicated by the movable-side mark 41a.

[0119] like Figure 7 As shown, a first locking protrusion 41b extending circumferentially is provided on the inner circumferential surface of the base end of the cup component 41. Figure 6 As shown, the first locking protrusion 41b engages with the locking groove 32e provided in the second cylindrical component 32, and can move circumferentially within the locking groove 32e. Therefore, with the movable unit 40 installed on the base unit 30, the cup component 41 (movable unit 40) is assembled so that it can rotate freely about the axis center relative to the second cylindrical component 32 (base unit 30) without falling off.

[0120] like Figure 7 As shown, a plurality of elongated second locking protrusions 41c extending along the axial (length direction) of the cup component 41 are provided on the inner circumferential surface of the cup component 41. Figure 7 In this example, three second locking protrusions 41c are arranged at approximately 90-degree intervals along the circumference. The lower end of each second locking protrusion 41c is connected to a locking groove 42c provided in the movable ring 42. Figure 8 The movable ring 42 and the cup component 41 are thus fitted together.

[0121] like Figure 5 and Figure 8 As shown, the movable ring 42 includes: an annular flange portion 42a, which abuts against the front end (second rubber ring 34) of the base unit 30; and a bent piece 42b, which is integrally formed with the flange portion 42a. The movable ring 42 is made of a rigid plastic material with elastic properties (e.g., polyacetal resin, polyamide resin).

[0122] The flange portion 42a is provided with: a notch-shaped locking groove 42c, which is fitted with the base end of the second locking protrusion 41c provided on the inner circumferential surface of the cup member 41; and a notch-shaped engaging recess 42d, which is engaged with the elastic piece 32f (protrusion) provided on the second cylindrical member 32. In the illustrated example, the locking groove 42c and the second locking protrusion 41c are similarly provided in three circumferentially spaced positions, and the engaging recesses 42d are provided in the same number of positions as the base side marking 32d at the same intervals along the circumferential direction.

[0123] As described above, if the base of each second locking protrusion 41c engages with the corresponding locking groove 42c, the movable ring 42 and the cup component 41 rotate together around the axis center. In addition, during the rotation of the movable unit 40, if the protrusion of the elastic sheet 32f repeatedly engages and disengages with each locking recess 42d, the rotational resistance will vary in strength (tapping sensation).

[0124] This tapping sensation allows the user to detect, through touch, any changes in air volume caused by the rotation of the movable unit 140 during use of the sperm collection device 1. Furthermore, it helps to prevent the movable unit 140 from rotating against the user's will.

[0125] The bending piece 42b is a circumferentially elongated plate-like component that is bent in accordance with the inner circumferential surface of the front end of the base unit 30 (the inner circumferential surface of the second rubber ring 34). When the movable unit 40 (cup component 41) rotates about the axis center, the bending piece 42b moves circumferentially along the inner circumferential surface of the front end of the base unit 30.

[0126] A circumferentially elongated curved sheet side opening 42e (first opening) is provided on the curved sheet 42b. The curved sheet side opening 42e is configured to accommodate a plurality of rubber ring side openings 34c (a plurality of second openings) provided on the second rubber ring 34 within the opening range.

[0127] like Figure 6 As shown, with the movable unit 40 installed on the base unit 30, the inner circumferential surface of the base end of the cup member 41 coincides with the outer circumferential surface of the base end of the second cylinder member 32. The overlapping portion of the bent piece 42b and the second cylinder member 32 clamps the second rubber ring 34, and the portion except for the opening 34c on the rubber ring side is installed in an airtight state.

[0128] Furthermore, an airflow path AP is formed between the inner circumferential surface of the base end of the cup component 41 and the outer circumferential surface of the base end of the second cylinder component 32, via a base-side marking 32d. Thus, the inner space IS of the container 20 is connected to the outside of the container 20 via the rubber ring-side opening 34c (adjustment mechanism AD) and the airflow path AP.

[0129] <Adjustment Agency AD>

[0130] The adjustment mechanism AD adjusts the airflow (air flowability) circulating inside and outside the container 20. In the sperm collection device 1 of the first embodiment, the adjustment mechanism AD is composed of the front end of the base unit 30 (the front end 32b of the second cylinder component 32 and the rubber ring side opening 34c) and the base end of the movable unit 40 (the movable ring 42 and the bending plate side opening 42e).

[0131] The adjustment mechanism AD will be explained below. Figure 9 (a) in the figure is a partially enlarged sectional view near the adjustment mechanism AD. Figure 9 (b) in the diagram illustrates the airflow near the adjustment mechanism AD. Figure 10 This diagram illustrates the rotation operation of the movable unit 40. Figure 11 Figure (a) illustrates the positional relationship between the curved blade side opening 42e and the rubber ring side opening 34c when the air flow is set to its minimum using the adjustment mechanism AD. Figure 11 Figure (b) illustrates the positional relationship between the curved blade side opening 42e and the rubber ring side opening 34c when the air flow is set to maximum using the adjustment mechanism AD.

[0132] like Figure 9 As shown in (a), if the curved sheet side opening 42e is moved circumferentially and the plurality of rubber ring side openings 34c are located within the opening range of the curved sheet side opening 42e, then as shown in (a), Figure 9 As indicated by arrow "AF" in (b), the inner space IS of container 20 is connected to the outside of container 20 via airflow path AP, rubber ring side opening 34c, and curved plate side opening 42e. At this time, the airflow rate circulating inside and outside container 20 is determined by the total opening area of ​​the rubber ring side openings 34c located within the opening range of the curved plate side opening 42e, i.e., the number of rubber ring side openings 34c (the number of holes).

[0133] like Figure 10 As shown, the airflow inside and outside the container 20 can be adjusted by rotating the movable unit 40 about its axis relative to the base unit 30. That is, as the movable unit 40 rotates, the bending piece 42b moves circumferentially, which can change the circumferential relative position between the opening 42e on the bending piece side and the opening 34c on the rubber ring side.

[0134] For example, in Figure 11 In the state shown in (a), air is most difficult to flow because the opening 34c on the rubber ring side is not located within the opening range of the opening 42e on the bending sheet side. On the other hand, in Figure 11In the state shown in (b), the multiple rubber ring side openings 34c are all located within the opening range of the bending sheet side opening 42e, so air flows most easily.

[0135] Moreover, in Figure 11 The state shown in (a) is the same as Figure 11 In the intermediate state shown in (b), the airflow is changed according to the sum of the opening areas (number of holes) of the rubber ring side opening 34c within the opening range of the curved sheet side opening 42e.

[0136] <Summary of the First Implementation>

[0137] In the sperm collection device 1 of the first embodiment, the overlapping part (opposing part) of the inner peripheral surface of the base end side portion of the movable unit 40 and the outer peripheral surface of the front end side portion of the base unit 30 has an air flow path AP. An adjustment mechanism AD that adjusts the air flow rate flowing inside and outside the container 20 is provided between the air flow path AP and the inner space IS of the container 20. The air flow rate can be adjusted according to the rotation angle of the movable unit 40 relative to the base unit 30. Therefore, it is less likely that the user's finger will accidentally block the air flow path AP, and the stimulation of the penis P that is not desired by the user can be suppressed.

[0138] <Sperm Collection Apparatus 1A of the Second Embodiment>

[0139] In the sperm collection device 1 of the first embodiment described above, the air resistance of the adjustment mechanism AD is changed according to the sum of the opening areas of the rubber ring side openings 34c within the opening range of the curved sheet side opening 42e (the number of rubber ring side openings 34c), thereby adjusting the stimulation of the anterior end PT of the penis P, but not limited to this structure.

[0140] For example, such as Figure 12 As shown, the rubber ring side opening 134c (second opening) and the base side opening 132c (second opening) can also be configured to be composed of a variety of openings with different opening areas. Depending on the rotation angle of the movable unit 140 relative to the base unit 130, any one of the groups of multiple rubber ring side openings 134c and base side openings 132c is located inside the movable cylinder side opening 142g (first opening).

[0141] The sperm collection apparatus 1A of the second embodiment configured in this manner will now be described. Figure 12 This is an exploded perspective view illustrating the main parts of the sperm collection device 1A according to the second embodiment. Figure 13 Figure (a) illustrates the state when one of the multiple rubber ring side openings 134c is selected. Figure 13Figure (b) illustrates the state when the opening 134c on the rubber ring side is not selected.

[0142] Figure 12 The sperm collection device 1A shown includes: a plurality of base-side openings 132c (second openings) disposed on the side of the front end 132b of the base unit 130 (second cylindrical component 132); a plurality of rubber ring-side openings 134c (second openings) disposed on the second rubber ring 134; and a movable cylindrical side opening 142g (first opening) disposed on the movable ring 142.

[0143] Furthermore, in this sperm collection apparatus 1A, structures identical to those in the sperm collection apparatus 1 of the first embodiment are given the same reference numerals and their descriptions are omitted. Additionally, since structures not shown are identical to those in the sperm collection apparatus 1 of the first embodiment, their descriptions are also omitted.

[0144] Similar to the base unit 30 in the first embodiment, the base unit 130 includes a first cylindrical component 131, a second cylindrical component 132, a first rubber ring (not shown), and a second rubber ring 134. Furthermore, the structures of the first cylindrical component 131 and the first rubber ring are the same as those of the first cylindrical component 31 and the first rubber ring 33 in the first embodiment, so their description is omitted.

[0145] The second cylindrical component 132 is a cylindrical shape open at both ends along the axial direction, and a V-shaped recess 132a is provided along its entire circumference in the middle of the axial direction. The portion of the second cylindrical component 132 closer to the base end than the recess 132a in the second cylindrical component 132 is fitted into the inner circumference of half of the front end side of the first cylindrical component 131. Similar to the first rubber ring 33 in the first embodiment, the first rubber ring is sandwiched between the second cylindrical component 132 and the first cylindrical component 131 to connect the cylindrical components 131 and 132 in an airtight manner.

[0146] Multiple base-side openings 132c are formed circumferentially on the side of the front end 132b of the second cylindrical component 132. In the illustrated example, the base-side openings 132c are composed of small circular holes, and nine are formed circumferentially. The opening areas of each base-side opening 132c are different. The base-side opening 132c (1) located at the left end of the figure has the largest opening area, and the base-side opening 132c (9) located at the right end has the smallest opening area.

[0147] On the inner circumferential surface of the front end 132b of the second cylindrical member 132, a locking recess 132d, consisting of multiple grooves (recesses), is provided at positions on opposite sides of the circumferential direction starting from each base-side opening 132c. Additionally, multiple protrusions 132e, serving as check valves for the second rubber ring 134, are formed at circumferential intervals on the front end 132b of the second cylindrical member 132. In the illustrated example, four protrusions 132e are formed at 90-degree intervals.

[0148] The second rubber ring 134 includes an annular portion 134a, a curved piece 134b integrally formed with the annular portion 134a and elongated circumferentially, and a rubber ring-side opening 134c provided in the curved piece 134b. Similar to the second rubber ring 34 of the first embodiment, the second rubber ring 134 of the second embodiment is also made of a synthetic resin (such as various rubber materials or elastomers with rubber elasticity) that has both softness and sealing properties.

[0149] The annular portion 134a is the portion placed on the front end face of the second cylindrical member 132, and notches 134d are formed at 90-degree intervals along the circumference to engage with the protrusions 132e provided on the front end of the second cylindrical member 132. The bent piece 134b matches and is bent to the inner circumferential surface of the front end of the second cylindrical member 132, and is configured to cover the entire base-side opening 132c (e.g., a long rectangle).

[0150] Similar to the substrate-side opening 132c, a plurality of rubber ring-side openings 134c are formed at circumferential intervals. In the illustrated example, each rubber ring-side opening 134c consists of nine circular holes of different areas, with the rubber ring-side opening 134c (1) at the left end having the largest area and the rubber ring-side opening 134c (9) at the right end having the smallest area. In this embodiment, the shape (opening area) and formation position of each rubber ring-side opening 134c and the corresponding substrate-side opening 132c are consistent with each other.

[0151] Additionally, a generally quadrilateral rib 134e is formed on the inner circumferential surface of the curved piece 134b, each rib individually surrounding the rubber ring-side opening 134c. Furthermore, the inner circumference of the rib 134e located at the right end does not have a rubber ring-side opening 134c.

[0152] The movable ring 142 includes: an annular flange portion 142a, which abuts against the front end (second rubber ring 134) of the base unit 130; and a movable cylinder 142b, which is disposed on the flange portion 142a. A notch-shaped locking groove 142c is provided in the flange portion 142a, which is for the base end of the second locking protrusion 41c disposed on the inner peripheral surface of the cup member 41 to engage. Therefore, the movable ring 142 rotates together with the cup member 41 about the axis center.

[0153] A movable cylinder side opening 142g (first opening) is provided on the movable cylinder 142b. The movable cylinder side opening 142g is a rectangular opening, and one of a plurality of rubber ring side openings 134c can be individually arranged inside it.

[0154] A locking protrusion 142d is formed at a position 180 degrees circumferentially rotated from the movable cylinder side opening 142g in the movable cylinder 142b. The locking protrusion 142d protrudes outward from the circumferentially elongated leaf spring portion 142e. In this embodiment, the leaf spring portion 142e is provided by two circumferentially elongated slits 142f spaced apart axially.

[0155] When any one of the plurality of rubber ring-side openings 134c is disposed inside the movable cylinder-side opening 142g, the engaging protrusion 142d engages with one of the plurality of engaging recesses 132d provided on the inner peripheral surface of the front end of the second cylinder component 132. When the engaging protrusion 142d engaged in the engaging recess 132d moves to an adjacent engaging recess 132d, the rotational resistance of the movable unit 140 changes in strength (tapping sensation).

[0156] This tapping sensation allows the user to detect changes in air volume caused by the rotation of the movable unit 140. Furthermore, it helps prevent the movable unit 140 from rotating against the user's will.

[0157] In the sperm collection device 1A of the second embodiment, the second rubber ring 134 is installed on the second cylindrical component 132 with the inner peripheral surface of the front end of the second cylindrical component 132 facing the outer peripheral surface of the curved piece 134b of the second rubber ring 134 facing each other, and the circumferential positions of each base-side opening 132c (second opening) and each rubber ring-side opening 134 (c second opening) matching.

[0158] Furthermore, by mounting the outer peripheral surface of the movable cylinder 142b, which is rotatable in the circumferential direction, in a state opposite to the inner peripheral surface of the curved piece 134b of the second rubber ring 142, any one of the plurality of rubber ring side openings 134c is located inside the movable cylinder side opening 142g (first opening).

[0159] exist Figure 13 In the example shown in (a), the movable cylinder side opening 142g is positioned at the fifth rubber ring side opening 134c (5) from the left end. Thus, the movable cylinder side opening 142g, the rubber ring side opening 134c (5) and the base side opening 132c (5) are connected, so air flows inside and outside the container 20 at a flow rate corresponding to the opening area (flow resistance) of each opening 142g, 134c (5) and 132c (5).

[0160] exist Figure 13 In the example shown in (b), the movable unit 40 (cup component 41, movable ring 42) is moved from... Figure 13In state (a), the cylinder begins to rotate clockwise, so that the movable cylinder side opening 142g is located on the inner circumference of the rib 134e of the side opening 134c without the rubber ring. In this state, air flows only through the gap between the movable unit 40 and the base unit 30, and the gap between the insertion space ES and the penis P, which is the state with the strongest stimulation to the penis P.

[0161] Since the opening areas of the multiple rubber ring-side openings 134c and the multiple base-side openings 132c are different, the airflow rate circulating inside and outside the container 20 is adjusted according to the rotation angle of the movable unit 40 relative to the base unit 30. Therefore, the intensity of stimulation to the penis P can be adjusted according to this rotation angle.

[0162] <Sperm Collection Device 1B of the Third Embodiment>

[0163] In the sperm collection device 1A of the aforementioned second embodiment, a movable cylinder side opening 142g (first opening) is a structure that selects one of a group of multiple rubber ring side openings 134c and base side openings 132c with different opening areas (second opening), but is not limited to this structure.

[0164] For example, Figure 14 As shown, it can also be configured such that one of the multiple movable cylinder side openings 242d (first openings) with different opening areas is located in a rubber ring side opening 234c (second opening).

[0165] The sperm collection device 1B of the third embodiment configured in this manner will now be described. Figure 14 (a) is an exploded perspective view illustrating the main parts of the sperm collection device 1B according to the third embodiment. Figure 14 Figure (b) illustrates the movable cylinder-side opening 242d provided on the movable ring 242. Figure 15 This is a cross-sectional view of the second rubber ring 234. Figure 16 (a) in the figure is a longitudinal sectional view of container 20B. Figure 16 (b) is a partially enlarged sectional view near the adjustment mechanism AD2.

[0166] Figure 14 The sperm collection device 1B shown in (a) includes: a base-side groove 232c disposed at the front end 232b of the base unit 230 (second cylinder component 232); a rubber ring-side opening 234c (second opening) disposed on the second rubber ring 234; and a plurality of movable cylinder-side openings 242d (first openings) disposed on the movable ring 242.

[0167] Furthermore, in the sperm collection apparatus 1B of the third embodiment, the same reference numerals are assigned to structures identical to those in the sperm collection apparatus 1 of the first embodiment, and their descriptions are omitted. Additionally, since structures not shown are identical to those in the sperm collection apparatus 1 of the first embodiment, their descriptions are also omitted.

[0168] Similar to the base unit 30 in the first embodiment, the base unit 230 includes a first cylindrical component 231, a second cylindrical component 232, and a first rubber ring 233 (see reference). Figure 16 The first cylindrical component 231 and the first rubber ring 234 are the same as those in the first embodiment. Therefore, their description is omitted.

[0169] The second cylindrical component 232 is a cylindrical shape open at both ends along the axial direction, and has a roughly V-shaped recess 232a along its entire circumference in the middle of the axial direction. A portion of the second cylindrical component 232 closer to the base end than the recess 232a fits into the inner circumference of half of the front end side of the first cylindrical component 231. For example... Figure 16 As shown, the first rubber ring 233 is sandwiched between the base end of the second cylindrical component 232 and the first cylindrical component 231, connecting the cylindrical components 231 and 232 in an airtight state.

[0170] The base-side groove 232c located at the front end 232b of the second cylindrical component 232 is formed by a groove open at the front end. In the illustrated example, the base-side groove 232c is formed by a U-shaped groove, but is not limited to this shape. For example, the base-side groove 232c may also be formed by a quadrilateral groove open at the front end.

[0171] At the front end 232b of the second cylindrical component 232, a plurality of engaging slits 232d are provided on the opposite side along the circumferential direction, starting from the base-side groove 232c. Each engaging slit 232d is a quadrilateral slit that is open at the front end and elongated along the axial direction. In this example, 10 engaging slits 232d are provided at circumferential intervals.

[0172] like Figure 14 (a) and Figure 15 As shown, the second rubber ring 234 includes: a cylindrical portion 234a; an annular portion 234b, which is integrally formed with the front end of the cylindrical portion 234a; and a rubber ring side opening 234c, which is provided on the side of the cylindrical portion 234a. The second rubber ring 234 of the third embodiment is also made of a synthetic resin (various rubber materials or rubber elastomers) that has softness and sealing properties, just like the second rubber ring 34 of the first embodiment.

[0173] The annular portion 234b is provided in a state in which it expands outward from the front end of the cylindrical portion 234a and is slightly inclined toward the base end.

[0174] The opening 234c on the rubber ring side is an elongated ellipse with a longitudinal length (axial length) longer than its transverse length (circumferential length), and extends through the thickness direction of the cylindrical portion 234a. An elliptical rib 234d protrudes along the inner diameter direction on the inner circumferential surface of the cylindrical portion 234a and runs along the edge of the opening 234c on the rubber ring side.

[0175] The movable ring 242 includes: an annular flange portion 242a, which abuts against the annular portion 234b of the second rubber ring 234; and a movable cylinder 242b, which is integrally formed with the flange portion 242a. A notch-shaped locking groove 242c is provided on the flange portion 242a, which is fitted with the base end of the second locking protrusion 41c provided on the inner circumferential surface of the cup member 41. Therefore, the movable ring 242 rotates together with the cup member 41 about its axial center. In this embodiment, the movable ring 242 is made of a rigid plastic material with elastic properties (e.g., polyacetal resin, polyamide resin).

[0176] like Figure 14 As shown in (b), a plurality of movable cylinder side openings 242d (first openings) are provided on the movable cylinder 242b. Each movable cylinder side opening 242d is a small hole with a different opening area and is spaced apart circumferentially.

[0177] In this embodiment, nine movable cylinder side openings 242d are provided, located at... Figure 14 The opening area of ​​the movable cylinder side opening 242d(1) at the left end of (b) is the smallest, while the opening area of ​​the movable cylinder side opening 242d(9) at the right end is the largest. The opening area gradually increases from the left end to the right end.

[0178] The shape and size of each movable cylinder side opening 242d are determined to be the shape and size that are accommodated within the opening of the rubber ring side opening 234c. In addition, the circumferential spacing between adjacent movable cylinder side openings 242d is determined to be such that only one movable cylinder side opening 242d is arranged within the rubber ring side opening 234c, but it can also be set to a spacing that allows multiple movable cylinder side openings 242d to be arranged within the rubber ring side opening 234c.

[0179] like Figure 14 As shown in (a), a guide plate 242e is provided within the forming range of each movable cylinder-side opening 242d on the inner circumferential surface of the movable cylinder 242b. The guide plate 242e is installed at a distance from the inner circumferential surface of the movable cylinder 242b toward the inner diameter side by means of mounting ribs 242f, and the core member 10 in the tilted state can abut against the inner circumferential surface of the guide plate 242e.

[0180] The guide plate 242e prevents the core component 10 from blocking the openings 242d on each movable cylinder side when it is tilted. That is, the guide plate 242e can be said to be a guiding component for ensuring the ventilation of each movable cylinder side opening 242d.

[0181] A locking protrusion 242g is formed at a position 180 degrees circumferentially rotated from the position of the guide plate 242e in the movable cylinder 242b. Similar to the second embodiment, the locking protrusion 242g protrudes outward from the circumferentially elongated leaf spring portion 242h.

[0182] The engaging protrusion 242g engages with the engaging slit 232d provided at the front end 232b of the second cylindrical component 232. When any one of the plurality of movable cylindrical side openings 242d is disposed inside the rubber ring side opening 234c, the engaging protrusion 242g engages with each engaging slit 232d. When the engaging protrusion 242g engaged in the engaging slit 232d moves to the adjacent engaging slit 232d, the rotational resistance of the movable unit 240 changes in strength (tapping sensation).

[0183] This tapping sensation allows the user to detect changes in air volume caused by the rotation of the movable unit 140. Furthermore, it helps prevent the movable unit 140 from rotating against the user's will.

[0184] like Figure 16 As shown, in the sperm collection device 1B of the third embodiment, the inner peripheral surface of the base end of the movable unit 240 is also configured to overlap with the outer peripheral surface of the front end of the base unit 230 in a state of opposition. An air flow path AP for supplying air to circulate inside and outside the container 20 and an adjustment mechanism AD2 for adjusting the air flow rate of the air flow path AP are provided on the overlapping part of each peripheral surface.

[0185] The adjustment mechanism AD2 is composed of the front end of the base unit 230 (the front end 232b of the second cylinder component 232 and the rubber ring side opening 234c) and the base end of the movable unit 240 (the movable ring 242 and the movable cylinder side opening 242d).

[0186] Furthermore, by marking 32d on the matrix side (refer to...) Figure 4 An airflow path AP is formed between the inner circumferential surface of the base end of the cup component 41 and the outer circumferential surface of the front end of the base unit 230, and the inside and outside of the container 20B are connected via the airflow path AP and the adjustment mechanism AD2. Furthermore, in the sperm collection device 1B of the third embodiment, there is one rubber ring-side opening 234c, therefore, a base-side marker 32d is provided. On the other hand, a number of movable-side markers 41a corresponding to the number of movable-cylinder-side openings 242d are provided circumferentially at intervals (see reference). Figure 4 ).

[0187] Furthermore, the adjustment mechanism AD2 adjusts the airflow (air flow rate) circulating inside and outside the container 20B based on the area of ​​a movable cylinder side opening 242d located inside the rubber ring side opening 234c.

[0188] Figure 17 Figure (a) illustrates the state where none of the multiple movable cylinder side openings 242d are selected. Figure 17 Figure (b) illustrates the state when one of the multiple movable cylinder side openings 242d is selected. Figure 17 Figure (c) illustrates the state when other movable cylinder side openings 242d are selected.

[0189] exist Figure 17 In the example shown in (a), none of the multiple movable cylinder side openings 242d are positioned within the rubber ring side opening 234c. In this state, air flows only through the gap between the movable unit 240 and the base unit 230, and the gap between the insertion space ES and the penis P, resulting in the strongest stimulation of the penis P.

[0190] exist Figure 17 In the example shown in (b), the fifth movable cylinder side opening 242d (5) from the left end is positioned at the rubber ring side opening 234c, so air flows with a flow path resistance corresponding to the area of ​​the fifth movable cylinder side opening 242d (5). In this state, with Figure 17 Compared to the example shown in (a), the stimulation of the penis P is weaker.

[0191] exist Figure 17 In the example shown in (c), the movable cylinder side opening 242d (9) at the right end, which has the largest area, is located at the rubber ring side opening 234c. Therefore, with Figure 17 Compared to the example shown in (b), the stimulation of the penis P is further weakened.

[0192] In this way, in the sperm collection device 1B of the third embodiment, the airflow inside and outside the container 20B is also adjusted according to the rotation angle of the movable unit 240 (cup component 41) relative to the base unit 230. Therefore, the intensity of stimulation to the penis P can be adjusted according to this rotation angle.

[0193] <Variation Example>

[0194] In the aforementioned embodiments, the inner peripheral surface of the base end of the movable units 40, 140, and 240 is positioned opposite to the outer peripheral surface of the front end of the base units 30, 130, and 230, and a second rubber ring 34, 134, and 234 with a rubber ring side opening 34c, 134c, and 234c is sandwiched between the two peripheral surfaces, but the structure is not limited to this.

[0195] For example, in the aforementioned embodiments, the adjustment mechanisms AD, AD1, AD2, and AD2' are located at the middle position in the axial direction of the container 20, but they can also be located at the upper end in the axial direction (upper side, upper surface).

[0196] Alternatively, a dual structure can be adopted, where the front end of the base unit 30, etc., is configured as an outer peripheral wall and an inner peripheral wall, and the base end of the movable unit 40, etc., is fitted into a groove between the outer peripheral wall and the inner peripheral wall of the front end of the base unit, so that the second rubber ring 34, etc., is sandwiched between the base end of the movable unit and the inner peripheral wall of the base unit. In this structure, the side of the base end of the movable unit 40, etc., and the inner peripheral wall of the base unit 30, etc., are opposite each other through the second rubber ring 34, etc. Therefore, by providing openings on the side of the base end of the movable unit 40, etc., the inner peripheral wall of the base unit 30, etc., and the second rubber ring 34, etc., the same effect as the above-described embodiments can be obtained.

[0197] In the aforementioned embodiments, the insertion space ES of the core component 10 is not connected to the inner space IS of the container 20, but as Figure 1 As shown, a valve 11f can also be provided near the front end of the core component 10 to connect the inner space IS of the container 20 with the insertion space ES of the core component 10.

[0198] Valve 11f is provided on a part of the core component 10 (e.g., the front end) and is a linear cut that runs through the thickness direction of the cylindrical portion 11c. Valve 11f is normally closed by the elasticity of the elastic material itself. On the other hand, it opens when the air pressure in the insertion space ES rises to a certain level, thereby connecting the insertion space ES with the inner space IS and allowing air to be discharged.

[0199] In this way, valve 11f allows air to be discharged from the insertion space ES to the inner space IS of the container 20, thereby restricting the inflow of air from the inner space IS of the container 20 to the insertion space ES.

[0200] Regarding the adjustment mechanisms AD, AD1, and AD2, in the aforementioned embodiments, the movable rings 42, 142, and 242 are provided with a curved plate-side opening 42e or a movable cylinder-side opening 142g or 242d, and the base units 30, 130, and 230 are provided with a rubber ring-side opening 34c, 134c, 234c or a base-side opening 132c, but are not limited to these structures.

[0201] The adjustment mechanisms AD, AD1, and AD2 only need to be able to adjust the airflow inside and outside the containers 20, 20A, and 20B according to the rotation angle of the movable unit 40 relative to the base unit 30.

[0202] Figure 18 This figure illustrates the movable ring 242' of the sperm collection device 1B' in a modified example of the third embodiment. Figure 19 Figure (a) illustrates the state where the movable cylinder side opening 242j and the rubber ring side opening 234c do not overlap. Figure 19 (b) in the diagram illustrates adjusting the airflow to a moderate level. Figure 19 (c) in the diagram illustrates the state where the airflow is adjusted to the maximum.

[0203] like Figure 18 As shown, the sperm collection device 1B' includes a movable ring 242'. The movable ring 242' includes a movable cylinder-side opening 242j (first opening). The movable cylinder-side opening 242j is circumferentially elongated, and the opening height (axial spacing) varies depending on the circumferential position. Figure 18 The movable cylinder side opening 242j in the example is a generally triangular shape that is elongated circumferentially. Specifically, the opening height (axial spacing) of the movable cylinder side opening 242j is smallest at one circumferential end (left end) and largest at the other circumferential end (right end). Therefore, the opening height of the movable cylinder side opening 242j increases (continuously increases) from one circumferential end to the other end, and decreases (continuously decreases) from the other circumferential end to the first end. Furthermore, the shape of the movable cylinder side opening 242j is not limited to... Figure 18 Examples.

[0204] like Figure 19 As shown, the circumferential length of the opening 234c (second opening) on ​​the rubber ring side of the second rubber ring 234 is shorter than the circumferential length of the opening 242j on the movable cylinder side, and the opening height is greater than or equal to the opening height (maximum axial spacing) at the other end of the circumferential direction of the opening 242j on the movable cylinder side.

[0205] Furthermore, in the sperm collection device 1B' of the modified embodiment of the third embodiment, since other structures are the same as those of the sperm collection device 1B of the third embodiment, their description is omitted.

[0206] exist Figure 19In the adjustment mechanism AD2' shown, the area of ​​the movable cylinder side opening 242j (first opening) located within the rubber ring side opening 234c (second opening) is changed according to the rotation angle of the movable unit 130 relative to the base unit 230. Furthermore, in the adjustment mechanism AD2', the airflow rate (air flowability) circulating inside and outside the container is adjusted according to the area of ​​the movable cylinder side opening 242j located within the rubber ring side opening 234c.

[0207] exist Figure 19 In the example shown in (a), the movable cylinder side opening 242j is not located within the rubber ring side opening 234c. In this state, air flows only through the gap between the movable unit 240 and the base unit 230, and the gap between the insertion space ES and the penis P, resulting in the strongest stimulation of the penis P.

[0208] exist Figure 19 In the example shown in (b), the circumferential center of the movable cylinder-side opening 242j is located within the rubber ring-side opening 234c, so air flows through the flow path resistance corresponding to the area of ​​the overlapping portion of each opening 234c, 242j. In this state, with Figure 19 Compared to the example shown in (a), the stimulation of the penis P is weaker.

[0209] exist Figure 19 In the example shown in (c), the circumferential right end of the movable cylinder side opening 242j is located inside the rubber ring side opening 234c, therefore it is related to... Figure 3 Compared to the example shown in (b), the stimulation of the penis P is further weakened.

[0210] Regarding core component 10, not limited to... ​ The structure can be varied. For example, the number of pieces in the ring component 12 can be set to 1 or 2, or it can be omitted.

[0211] Regarding the shape of the cup component 41, it is not limited to a cup shape if it can rotate about the axis center relative to the base unit 30. For example, the shape of the cup component 41 can also be set as a cuboid shape.

[0212] Regarding the airflow path AP, in the foregoing embodiments, a structure using a groove to create a base-side marking 32d for use as the airflow path AP was exemplified, but the structure is not limited to this. A groove may also be formed on the inner surface of the cup member 41, or a gap may be provided between the inner surface of the base end of the cup member 41 and the outer surface of the front end of the second cylinder member 32.
