Description

  The present invention relates to a sperm sampling device.

  Various sperm sampling devices for collecting male sperm have been proposed due to medical research and therapeutic needs. For example, medical needs such as examining the husband's sexual function from sperm collected to investigate the cause of infertility between couples, treating sexual dysfunction, and securing sperm for artificial insemination. A sperm collector is used for this. Furthermore, some sperm collectors of this kind are designed to prevent sexual crimes and prostitution by eliminating personal sexual desire, and to reduce the number of people infected with sexually transmitted diseases. In order to meet various needs, there is a simple sperm sampling device that can be obtained at a low price and is a disposable type that does not cause any problems in hygiene and health.

  For example, in Patent Document 1, a gel-like synthetic resin (styrene-based thermoplastic elastomer) interior material having a deep concave space inside a cylindrical cylindrical container body made of plastic having a required hardness and wall thickness. The inner surface of the interior material is provided with a plurality of small projections and folds protruding into the recessed space, and a sperm sampling device provided with an exterior material made of urethane resin so as to cover the interior material is proposed. Has been done. This sperm sampling device is configured such that the male genitals are inserted into the recessed space of the interior material housed in the container main body, and in the inserted state, the container main body is gripped to rub the male genitals. It is configured to perform a reciprocating operation.

  In addition, the applicant of the present application has proposed in Patent Literatures 1 to 5 a sperm sampling device in which a core member made of a gel resin is housed in a container body. However, since the core member made of a gel-like resin has the same internal temperature as the outside air temperature, especially when the outside air temperature is low, the inside temperature of the core member is, for example, 15 to 20 ° C. or higher than the body temperature of the user. If the temperature is low, discomfort and discomfort are increased due to the loss of body temperature during insertion of the male genitalia, which causes a problem that the usability is deteriorated or the male genitalia are atrophied.

  In order to eliminate such inconvenience, in the initial stage, a heater is used to heat the sperm sampling device, especially the core member from the outside to bring it closer to the body temperature, for example, by dipping it in hot water before use. Or heating with an infrared heater or a microwave oven was performed. However, this heating method has a problem of heat retention such that it is overheated to a high temperature state or the heat is reduced during use.

  As described above, the sperm sampling device has a configuration in which the core member is fixed in the container body made of resin having low thermal conductivity, so that the inside of the core member is heated to an appropriate temperature by heating from the outside of the container body. It was not easy to warm. Further, in such a heating method, there is a situation in which heating may take a long time or a safety problem due to overheating may occur.

  In view of the above points, the applicant of the present invention, in a sperm sampling device of a type in which a gel-like resin core member is housed in a plastic container body and sealed with a cap, the core member is concentrated from inside and properly. By heating to a temperature, a warming tool for a sperm sampling device that can safely and safely raise the temperature to a temperature close to the body temperature in a short time and always maintain a good feeling has been proposed (see Patent Document 6). ).

  The warming tool has a convex warming member protruding upward from a warming tool body accommodating an electric heating unit as a heating means, and a base pedestal that can be placed on a flat surface and a convex shape of the base pedestal. A middle cover having a flange portion around the lower portion of the cylindrical convex portion for inserting and covering the heating member, and a cylindrical convex portion of the middle cover fitted and concealing this, and a lower end portion of the middle cover And an outer cover fitted to the flange portion. When using the warming tool, insert the plug provided on the power cord of the electric heating unit into the outlet, remove the outer cover from the base pedestal, and then remove the exposed cylindrical convex portion of the inner cover from the sperm sampling device. Insert into the insertion opening of the core member. Next, the convex heating member of the base pedestal is inserted into the opening on the bottom surface side of the middle cover attached to the sperm sampling device, and the tip end surface of the core member is brought into close contact with the flange portion. Then, the switch is turned on to start heating by the electric heating unit. When a predetermined time has elapsed after the start of heating, the sperm sampling device is removed from the inner cover, and the inner cover is pulled out with the insertion port of the sperm sampling device facing upward. After inserting the finger into the insertion port after removing the middle cover and confirming that the internal temperature is appropriate, the sperm sampling device is ready for use.

  However, since the above conventional warmer is independent of the sperm sampling device, first, it is necessary to manage the warming device separately from the sperm sampling device. Secondly, since the warmer is composed of three parts, that is, the base pedestal, the middle cover and the outer cover, the number of parts is large and the manufacturing cost is high. Thirdly, since the electric heating unit is used as the heating means, it takes time and effort to insert the plug provided in the power cord into the outlet at the time of use and the place of use is limited. Fourth, when in use, remove the cap of the sperm sampling device, remove the outer cover of the warmer from the base pedestal, insert the cylindrical convex part of the middle cover into the sperm sampling device core member insertion port, the middle cover Since the heating is started after many operations such as inserting the convex heating member of the base pedestal into the opening on the bottom side of the, and turning on the switch, there are many preparation work steps before use and it is troublesome. Yes, it takes time.

Embodiment of the invention

  Next, an embodiment of the present invention will be described in detail with reference to the drawings. In the description, the upper side of FIGS. 1 and 4 is referred to as “upper” or “upper” and the lower side is referred to as “lower” or “lower”.

[First Embodiment]
As shown in FIGS. 1 and 2, a sperm sampling device T according to the first embodiment of the present invention includes a main body 10 and a warmer 20 integrally combined with the main body 10. The main body 10 has a cover portion 11 shown in the upper portion of FIG. 1, an outer layer portion 12 provided inside the cover portion 11, and an inner layer portion 13 further provided inside the cover portion 11. The cover portion 11 is formed of a thin hard synthetic resin and has a deep cup shape. The outer layer portion 12 is provided inside the cover portion 11, and is formed of a thick cup-shaped air-permeable flexible heat insulating material, for example, urethane foam. The inner layer portion 13 is provided inside the outer layer portion 12, is formed into a bottomed cylindrical shape with a material having super-flexibility, for example, an elastomer, and is provided with a soft foldd inner wall 13a at the center. The inner wall 13a forms an elongated insertion hole 13b. Normally, at least the inlet of the insertion hole 13b and the outer peripheral surface thereof are coated with a lubricating lotion or the like.

  The warmer 20 has a cap portion 21 and a heating unit 22 provided inside the cap portion 21. The cap portion 21 is substantially cylindrical and has an outer peripheral wall 21a and an inner peripheral wall 21b provided inside the outer peripheral wall 21a. The outer peripheral wall 21a extends slightly above the upper end of the inner peripheral wall 21b, and the extended end is elastically fitted to the outer periphery of the lower end of the cover 11 of the main body 10. With this configuration, the warmer 20 can be attached to and detached from the main body 10.

  A storage section 21c surrounded by the inner peripheral wall 21b and opening downward is formed in the cap portion 21, and the heating unit 22 is provided in the storage section 21c. The heating unit 22 has a tubular member 23 extending upward in the center, a heat generating agent 24 housed inside the tubular member 23, and a heat generation starting means 25 disposed below the tubular member 23. The tubular member 23 extends from the inner peripheral wall 21b in one direction along the central axis of the cap portion 21 and is inserted into the insertion hole 13b when the cap portion 21 is mounted on the main body 10. The heat generating agent 24 is a member that is housed in the tubular member 23 and supplied with water to generate heat. The heat generation starting means 25 is housed in the housing space 21c and is operated from the outside of the cap portion 21. When this operation is performed, the exothermic agent 24 starts a hydration reaction.

  The cylindrical member 23 is a cylindrical base portion 23a that rises from the upper inner peripheral surface of the inner peripheral wall 21b, and a cylinder that stands up from the upper end portion of the base portion 23a to a height substantially equal to the upper end portion of the cap portion 21 and is slightly thinner than the base portion 23a. It has integrally a shaped intermediate portion 23b and a cylindrical insertion portion 23c that stands up from the upper end of the intermediate portion 23b and is slightly thinner than the intermediate portion 23b. The tubular member 23 has a hollow portion 23d that communicates from the inner peripheral side space of the base portion 23a to the inner peripheral side space of the insertion portion 23c and also communicates with the accommodation space 21c of the cap portion 21. At the tip of the insertion portion 23c, a small hole 23e for communicating a hollow portion provided inside the insertion portion 23c to the outside is formed by a short cylinder 23f.

  The cylindrical small hole 23e at the tip of the insertion portion 23c is sealed by the circular tip film 26a, and the hollow portion of the insertion portion 23c is sealed at the lower end portion of the insertion portion 23c, that is, the upper end portion of the intermediate portion 23b. A circular intermediate film 26b is provided. In the insertion portion 23c, that is, in a part of the hollow portion 23d, water 27 is accommodated and a needle 28 is accommodated so as to be vertically movable. The tip film 26a and the intermediate film 26b are preferably those that have good adhesion and can be easily broken, for example, aluminum films.

  The needle 28 has a length substantially equal to the distance from the tip film 26a to the intermediate film 26b. The upper end portion 28a (see FIG. 2) of the needle 28 is axially movably inserted into the small hole 23e at the tip of the insertion portion 23c, and a minute gap is formed between the upper end portion 28a and the inner peripheral wall of the small hole 23e. It is left. Further, on the upper end portion 28a, an extremely thin flange 28b (FIG. 2) having an outer diameter slightly larger than the inner diameter of the small hole 23e is provided at a position away from the tip in the lower end direction by a distance shorter than the length of the small hole 23e. (See) is provided. Then, when the warmer 20 is incorporated into the main body 10, the upper end 28a is inserted into the small hole 23e from the hollow portion of the insertion portion 23c, but the upper end of the upper end 28a has a gap between the tip film 26a. It is in a certain state. When the heating operation of the heating unit 22 is performed, the flange 28b hits the tip of the cylindrical tube 23f forming the small hole 23e, and the needle 28 moves largely toward the tip of the tubular member 23. Have been thwarted.

  Three or four blades 28c extending to the lower end of the needle 28 are provided on the lower side of the upper end 28a of the needle 28. The blade 28c is wider toward the lower side. The reason why the three or four blades 28c are provided is to prevent the flow of the water contained in the insertion portion 23c from flowing down and to improve the stability of the vertical movement of the needle 28. A pressure receiving member 28d having an outer diameter slightly smaller than the inner diameter of the lower end of the insertion portion 23c is provided at the lower end of the needle 28. The pressure receiving member 28d makes it easier to receive a force from the slider 29 when the slider 29, which will be described in detail later, is pushed up, and has a shape structure that does not prevent the water 27 contained in the insertion portion 23c from flowing down, for example, with a hole. It is formed of a disc or a circular net.

  When operated by the user, the heat generation starting means 25 breaks the tip film 26a and the intermediate film 26b, causes the water 27 contained in the insertion portion 23c to flow down, and generates heat in the accommodation space 21c. It is mixed with the agent 24 to start an exothermic reaction.

  An example of the heat generation starting means 25 having such a function will be described. The illustrated heat generation starting means 25 has a slider 29 provided in the accommodation space 21c in close contact with the inner surface of the cylindrical inner peripheral wall 21b of the cap portion 21 so as to be slidable in the axial direction of the tubular member 23. As shown in FIG. 2, the slider 29 has a dish-shaped cup portion 29a and a heat generating agent holding portion 29b provided at the center of the cup portion 29a. The cup portion 29a has a center side portion 29a1 and an outer peripheral side portion 29a2, and the outer peripheral side portion 29a2 is bent at a boundary portion 29a3 between the two so as to be closer to the heat generating agent holding portion 29b. With such a configuration, when the slider 29 approaches the main body 10, the cup portion 29a slides on the base portion 23a while maintaining the shape of FIG. The exothermic agent holding portion 29b is formed in a cylindrical shape having an upward opening, and the exothermic agent 24 is put into and accommodated from the upper opening.

  The exothermic agent 24 is mainly composed of calcium oxide (slaked lime) powder, aluminum powder and additives, or calcium oxide powder, and is filled in a nonwoven fabric pack for easy handling.

  The exothermic agent holding portion 29b of the slider 29 has one or a plurality of slits (or water passage holes) on its peripheral surface. When the slider 29 is pushed up, the intermediate film 26b is broken, and the water flowing down from the insertion portion 23c passes through the water passage holes of the exothermic agent holding portion 29b and the exothermic agent 24 held in the exothermic agent holding portion 29b. Is mixed with.

  When the slider 29 is pushed and moved in the direction of the tubular member 23, the upper end of the exothermic agent holding portion 29b breaks the intermediate film 26b and further enters the insertion portion 23c to push up the pressure receiving member 28d of the needle 28. Therefore, the upper end portion 28a of the needle 28 projects upward from the small hole 23e of the insertion portion 23c, and at that time, the tip film 26a is broken. Due to the breakage of the intermediate film 26b, the water 27 in the tubular member 23 flows down into the cup portion 29a of the slider 29, and the hydration reaction with the exothermic agent 24 starts. Further, by breaking the tip film 26a, high-temperature steam generated by the hydration reaction can be ejected from the small hole 23e at the tip of the insertion portion 23c into the insertion hole 13b of the main body 10.

  When the exothermic agent 24 and water 27 are mixed, heat generation instantly starts. At room temperature around 25 ° C, the temperature reaches about 45 ° C after 4 minutes. The operation for starting the heat generating action is a simple operation of merely pushing up the slider 29, and the mixing speed of the heat generating agent 24 and the water 27 is always constant. Therefore, the inner layer portion 13 can be heated to a predetermined temperature in a substantially constant time regardless of which user uses it.

  The inner layer portion 13 is heated by the conduction heat from the heated water or steam in the insertion portion 23c inserted into the insertion hole 13b and the convection heat due to the steam ejected into the insertion hole 13b. It is highly efficient and can reach the required temperature in a relatively short time. Further, when the inner layer portion 13 is made of an elastomer, the heat capacity is large, and since the inner layer portion 13 is covered with the outer layer portion 12 having high heat insulation property, the suitable temperature holding time after the heating is increased. can do. Therefore, it is possible to prevent the inner layer portion 13 from having a temperature lower than the body temperature during use. Furthermore, the water droplets adhering to the inner wall 13a due to the water vapor ejected into the insertion hole 13b have the effect of enhancing the lubricity of the inner wall 13a.

[Second Embodiment]
In the case of the above-described first embodiment, when the sperm sampling device T is used, it is necessary to hold the main body 10 and push up the slider 29 at the bottom, so that workability is not good. Therefore, in the preferred second embodiment of the present invention (see FIGS. 3 to 8), the configuration of the heat generation starting means 25 is made easier for the user to handle. In the following, the same members as those in the first embodiment will be designated by the same reference numerals, and the description thereof will be omitted to simplify the description.

  The heat generation starting means 25 has a pusher 30 and a lower surface film 31 in addition to the slider 29 of the first embodiment. As shown in FIGS. 3 to 6, the heat generation starting means 25 includes a slider 29 provided slidably in the axial direction of the tubular member 23, a pusher 30 provided below the slider 29, and a pusher 30. And a lower surface film 31 disposed below the. The pusher 30 is movable outside the slider 29 (on the side opposite to the tubular member 23 of the slider 29) between a position where it does not project from the bottom surface of the cap portion 21 and a position where it projects, and in a projected state. When it is rotated, the slider 29 becomes immovable and has a function of sliding the slider 29 toward the tubular member 23 when the slider 29 and the main body 10 are pushed toward each other in the immovable state.

  Unlike the first embodiment, the slider 29 is provided with a horizontal plate-shaped receiving member 29c at the bottom. The outer peripheral surface of the receiving member 29c is slidably in contact with the inner surface of the inner peripheral wall 21b of the cap portion 21. Further, between the center of the receiving member 29c and the outer periphery of the receiving member 29c, three arc-shaped holes 29d are formed at equal intervals on a circle sharing the center of the receiving member 29c.

  On the other hand, the pusher 30 has a bottom plate 30a having a diameter substantially equal to that of the receiving member 29c of the slider 29. In the example of FIG. 2, it is formed in a three-pronged shape in order to reduce the weight, but it may be formed in a disc shape. A push-up member 30b extending upward is provided at a distance equal to the distance from the center of the bottom plate 30a to the hole 29d from the center of the slider 29. The push-up members 30b have the same number as the holes 29d of the slider 29, and are provided at equal intervals on the circumference centered on the center of the bottom plate 30a.

  In the illustrated example, a protrusion 30c projecting on the upper surface is provided at the center of the bottom plate 30a of the pusher 30. When the pusher 30 is held at a position where it does not project from the bottom surface of the cap portion 21, the convex portion 30c contacts the bottom portion of the exothermic agent holding portion 29b of the slider 29 and holds the slider 29 at an appropriate height. Alternatively, it is provided to set the position of the bottom plate 30a of the pusher 30 with respect to the bottom surface of the cap portion 21. It is preferable that the convex portion 30c is provided with a concave portion 30d that is open to the outside (lower surface).

  With the above-described configuration, as shown in FIG. 3, in the state before the completion of the sperm sampling device T (before the sale), the pusher 30 has the slider 29 in which the tip of each pushing-up member 30b is inserted into each hole 29d of the slider 29. Moved in the direction of 29. Then, the convex portion 30d of the bottom plate 30a of the pusher 30 hits the bottom portion of the exothermic agent holding portion 29b of the slider 29, and the upper end portion of the push-up member 30b of the pusher 30 contacts the bottom surface of the cup portion 21 of the slider 29. The pusher 30 is stopped in this state. At this time, the bottom surface of the bottom plate 30a of the pusher 30 is on the same surface as the bottom surface of the cap portion 21. Then, as an example, the plastic lower film 31 is peelably adhered so as to cover the bottom plate 30a of the pusher 30 and the bottom surface of the cap portion 21. In this state, it is offered to the market.

  Now, when using the sperm sampling device T of the second embodiment, the lower surface film 31 of FIG. 3 is peeled off, a fingertip is put in the concave portion 30d of the pusher 30, and as shown in FIG. When the pull-out member 30 is pulled out, the upper end portion of the push-up member 30b contacts the slider 29, and the pusher 30 is stopped at a predetermined position. When the pusher 30 is rotated around the axis of the main body 10 in a predetermined direction in that state, the push-up member 30b of the pusher 30 moves in the hole 29d of the slider 29 in the longitudinal direction thereof, and the upper end of the push-up member 30b is moved to the hole. Since it is engaged with 29d, the pusher 30 is fixed to the slider 29 so as to be immovable in the vertical direction while protruding from the bottom surface of the cap portion 21.

  When the pusher 30 is pulled out, the pusher 30 is stopped at a predetermined position, and when the pusher 30 is rotated in a predetermined direction, the pusher 30 moves vertically with respect to the slider 29 while protruding from the bottom surface of the cap portion 21. An example of the configuration for being fixed improperly will be described in detail with reference to FIGS. 7 and 8. 7A mainly shows the shape of the hole 29d of the slider 29, and FIG. 7B mainly shows the shape of the push-up member 30b of the pusher 30. As shown in FIG. FIG. 8 shows the action of the hole 29d of the slider 29 and the push-up member 30b of the pusher 30.

  As shown in FIG. 7, each of the holes 29d of the slider 29 is formed such that one half of the length in the circumferential direction is wide and the other half in the circumferential direction is narrow. The outer side of each hole 29d with respect to the center of the receiving member 29c exists on a common circumference, but the inner side of the narrow portion 29b2 of each hole 29d with respect to the center of the receiving member 29c has a corresponding hole. The wide portion 29d1 of 29d1 exists on a common circumference outside the inner side with respect to the center of the receiving member 29c.

  On the other hand, the push-up members 30b of the pusher 30 have the same number as the holes 29d of the slider 29, and are provided at equal intervals on the circumference centered on the center of the bottom plate 30a. Further, the horizontal cross-sectional shape of each push-up member 30b is an arc shape having the same curvature as the arc of the hole 29d of the slider 29, but the length in the circumferential direction is approximately half the length of the hole 29d of the slider 29. That's it. Further, as shown in FIG. 8, each pushing-up member 30b has a thick portion 30b1 standing upright from the lower end to near the upper end, a thin portion 30b2 formed on the upper side of the thick portion 30b1, and an upper end of the thin portion 30b2. The bent portion 30b3 protruding outward from the portion is integrally formed. The thickness of the thick portion 30b1 is substantially equal to the width of the wide portion 29d1 of the hole 29d of the slider 29, and the thickness of the thin portion 30b2 is substantially equal to the width of the narrow portion 29b2 of the hole 29d of the slider 29. The outer surfaces of the thick portion 30b1 and the thin portion 30b2 exist on one vertical curved surface, and a horizontal step surface 30b4 is formed at the boundary between the inner surface of the thick portion 30b1 and the inner surface of the thin portion 30b2. ing.

  With the above configuration, in the unused state of the sperm sampling device T, as shown in FIGS. 3 and 8 (a), the push-up member 30b of the pusher 30 has the thick portion 30b1 of the hole 29d of the slider 29. The thin portion 30b2, the step surface 30b4 and the bent portion 30b3 are inserted through the wide portion 29d1 and are located above the receiving member 29c of the slider 29. In this state, the pusher 30 cannot rotate about its central axis, but can be pulled downward. Then, as shown in FIG. 5, when the pusher 30 is pulled out downward from the cap portion 21, as shown in FIG. 8B, the thin portion 30b2 of the push-up member 30b becomes the wide portion 29d1 of the hole 29d of the slider 29. The pusher 30 can be rotated around its central axis, that is, in the case of FIG. When rotated, as shown in FIG. 8C, the thin portion 30b2 of the push-up member 30b moves to the narrow portion 29b2 of the hole 29d of the slider 29, and the bent portion 30b3 simultaneously forms the narrow portion 29b2 of the hole 29d. The upper surface of the receiving member 29c is in contact, and the step surface 30b4 is in contact with the upper and lower sides of the receiving member 29c. As a result, the pusher 30 cannot move vertically with respect to the slider 29.

  The sperm sampling device T in this state is placed upright on a flat surface such as a table, and the main body 10 is pushed down. Then, as shown in FIG. 6, the pusher 30 and the slider 29 are lifted in the accommodation space 21c of the cap portion 21 while being connected to each other. At this time, when the slider 29 rises to a position where the periphery of the cup portion 29a of the slider 29 comes into close contact with the ceiling wall of the base portion 23a of the tubular member 23, the upper end portion of the exothermic agent holding portion 29b of the slider 29 becomes the upper end portion of the insertion portion 23c. In order to break the intermediate film 26b, the water 27 in the insertion portion 23c flows down. Further, the needle 28 in the insertion portion 23c is pushed up by the upper end portion of the rising heating agent holding portion 29b, and the upper end portion 28a of the needle breaks the tip film 26a.

  After the water 27 flows down by pushing down the main body 10 and comes into contact with the heat generating agent 24, heat generation is started as in the case of the first embodiment, and as shown in FIG. Of the water vapor 32 is ejected into the insertion hole 13b of the main body 10, and the inner layer portion 13 can be heated to an appropriate temperature in a comparatively short time of about 4 to 5 minutes after the main body 10 is pushed down.

  When the warming by the warmer 20 is completed for a predetermined time, the main body 10 is grasped by one hand, the warmer 20 is grasped by the other hand, and the main body 10 is on the lower side and the warmer 20 is The heater 20 is tilted so as to be on the upper side, or in the opposite state, and the warmer 20 is pulled to be separated from the main body 10. In the separated warmer 20, the bottom surface of the cap portion 21 and the bottom surface of the pusher 30 are on the same plane, so that the tubular member 23 stands up on any plane, that is, in a stable state. You can put it in.

  In this way, the main body 10 from which the warmer 20 is removed can be used in a state where at least the inner layer portion 13 maintains an appropriate temperature.

[Other Embodiments]
The shape of the cup portion 29a of the slider 29, the shape of the heat generating agent holding portion 29b and the positional relationship with respect to the cup portion 29a, the shape of the pusher 30 and the connecting structure to the slider 29 are not limited to the above examples. The water in the insertion portion 23c of the tubular member 23 is dropped by the movement of the slider 29, comes into contact with the exothermic agent to generate heat, and water vapor is ejected from the tubular member 23 into the insertion hole 13b of the main body 10. As long as it has a structure, it can have any shape and structure.

  Further, as the exothermic agent, an exothermic agent such as iron powder that exothermically occurs due to an oxidation reaction may be used instead of the exothermic agent that causes exothermic reaction as described above. However, in that case, a structure that puts a heating agent in a highly airtight bag, breaks the bag when the slider is pushed up and contacts oxygen, and heats the water by the heat generation to generate water vapor can do. Further, instead of heating a liquid such as water, a heat generating agent which itself generates heat due to friction or the like may be adopted. In that case, a liquid such as water is unnecessary.

  In the above embodiment, the main body 10 and the warmer 20 are sold in a combined state, but they may be sold separately. In the sperm sampling device described above, it is preferable to use the collected sperm for medical purposes or the like, but the sperm may be discarded while the sperm are still contained. Further, although the main body 10 and the warmer 20 have a cylindrical shape, they may have other shapes such as a quadrangular prism shape. Although the liquid in the warmer 20 is water, it may be a mixed liquid in which water and other additives are mixed, or a liquid other than water.

  The length of the insertion portion 23c of the tubular member 23 is preferably about 50 to 60% of the length of the insertion hole 13b, but may be 40 to 80%. Further, it is preferable that the insertion portion 23c becomes thinner toward the tip as described above, but the insertion portion 23c may have substantially the same thickness as the tip hole. Furthermore, although the insertion portion 23c has a cylindrical shape, it may have another shape such as a triangular prism shape.
