Description

[Technical field]

[0001] The present invention relates to a closure which, together with a container body, constitutes a biological fluid storage container, and more particularly to a closure which constitutes a container for storing urine excreted from the human body. [Background technology]

[0002] Conventionally, a known container body that constitutes a biological fluid storage container is a urine container body that is integrally molded from a material having low hardness and high extensibility and includes a storage section for storing urine, a hollow attachment section that is connected to one side of the storage section and has an inlet portion for introducing the biological fluid, a hollow separation section that is formed toward the inside of the storage section at the site where the storage section and the attachment section are connected and that guides urine into the storage section, and a backflow prevention structure that is formed in the separation section and prevents the backflow of the biological fluid (Patent Document 1). In addition, as a closure that constitutes a biological fluid storage container together with the container body, a clip is known that closes the outlet portion of the container body, which has a hollow urine collection bag for storing urine, a urine discharge opening that communicates with one side of the urine collection bag for discharging urine, and a hollow discharge portion that has a fastening portion for discharging urine, thereby forming a urine storage container together with the container body (Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-123999 A [Patent Document 2] JP 2013-99502 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, these conventional urine storage containers have problems such as the container body not having an outlet, which requires the entire urine storage container to be removed from the penis when discharging the stored urine, which is cumbersome (Patent Document 1). Furthermore, if the container body has an outlet, it is necessary to bend the outlet to close it, which makes the closing operation cumbersome. Furthermore, the closure is made of a hard material, which causes discomfort when worn in close contact with the body (Patent Document 2).

[0005] In order to comprehensively solve these problems, prior to this application, the applicant had filed an invention relating to a biological fluid storage container consisting of a container body molded from a material having low hardness and high extensibility, and a closure body molded from a flexible material having a greater hardness than the container body (unpublished at the time of filing this application).However, the applicant subsequently discovered a new problem that if the container body is clamped and fixed by the closure body for a long period of time, permanent deformation will occur in the container body, which may result in a reduction in the closing effect due to deformation of the discharge part of the container body, blockage due to the inner walls of the discharge outlet sticking together, or damage due to the occurrence of cracks.

[0006] Therefore, the present invention is intended to solve the problems of the conventional technology, and further to solve new problems that the present inventors have found in the course of development.

[0007] In other words, the object of the present invention is to provide a closure that constitutes a biological fluid storage container together with a container body molded from a material having low hardness and high elongation, which reliably prevents leakage of biological fluid, allows easy operation for discharging the biological fluid, and prevents leakage of biological fluid due to elastic deformation of the container body due to external forces, and a biological fluid storage container equipped with this closure. [Means for solving the problem]

[0008] The invention according to claim 1 relates to a biological fluid storage container comprising a container body for storing a biological fluid and a closure for closing the container body, the container body being molded from a material having low hardness and high extensibility and comprising at least a hollow storage section for storing the biological fluid, a hollow inlet section having an inlet section communicating with one side of the storage section for introducing the biological fluid, and a hollow outlet section having an outlet section communicating with the other side of the storage section for discharging the biological fluid and a fastening section for discharging the biological fluid, the closure body comprising a first clamping arm section for clamping the outlet section and a second clamping arm section for clamping the discharge ... The above-mentioned problem is solved by the fact that the clamping arm comprises a connecting portion that connects one end of the first clamping arm portion and one end of the second clamping arm portion to be able to open and close freely, and a first closed end portion and a second closed end portion that are arranged at the other end of the first clamping arm portion and the second clamping arm portion and overlap each other inside and outside to form a closed portion in a closed state to form a clamping space, the first closed end portion and the second closed end portion being integrally molded with a first locking portion and a second locking portion that are respectively arranged at corresponding positions opposite each other.

[0009] The invention according to claim 2 is a closure body which comprises at least a hollow container part for containing a biological fluid, a hollow inlet part which is connected to one side of the container part and has an inlet part for introducing the biological fluid, and a hollow outlet part which is connected to the other side of the container part and has an outlet part and a fastening part for discharging the biological fluid, and which clamps and fixes the outlet part of the container body and constitutes a biological fluid storage container together with the container body, the closure body comprising a first clamping arm part and a second clamping arm part which clamp and close the outlet part. The clamping arm device comprises a clamping arm portion, a connecting portion that connects one end of the first clamping arm portion and the second clamping arm portion so as to be able to open and close freely, and a first closed end portion and a second closed end portion that are disposed at the other end of the first clamping arm portion and the second clamping arm portion and overlap each other inside and outside to form a closing portion in a closed state to form a clamping space, the first closed end portion and the second closed end portion being integrally molded with a first locking portion and a second locking portion that are respectively disposed at corresponding positions opposite each other, thereby solving the above-mentioned problem.

[0010] The invention of claim 3 further solves the above-mentioned problem by, in addition to the configuration of the invention of claim 2, the first clamping arm portion has a first pressing portion arranged in a protruding shape toward the clamping space, and the second clamping arm portion has a second pressing portion arranged in a protruding shape toward the clamping space, and by pressing the discharge portion of the container body between the first pressing portion and the second pressing portion.

[0011] The invention according to claim 4 further solves the above-mentioned problem by providing the first locking portion and the second locking portion with engaging protrusions having a triangular cross section that engage with each other in a non-return manner in the closed state, in addition to the configuration of the invention according to claim 2 or 3.

[0012] The invention of claim 5 further solves the above-mentioned problem by providing the first locking portion and the second locking portion with engaging hook pieces having an L-shaped cross section which engage with each other in a non-return manner in the closed state, and being integrally molded from a flexible material, in addition to the configuration of the invention of claim 2 or 3.

[0013] The invention according to claim 6 solves the above-mentioned problem by, in addition to the configuration of the invention according to claim 2 or 3, the first locking portion has a fitting hole, the second locking portion has a fitting protrusion corresponding to the fitting hole, and the first locking portion is integrally molded from a flexible material. Effect of the Invention

[0014] According to the biological fluid storage container of the invention of claim 1, the biological fluid storage container comprises a container body for storing biological fluid and a closure for closing the container body, the container body at least comprises a hollow storage section for storing the biological fluid, a hollow inlet section having an inlet section connected to one side of the storage section for introducing the biological fluid, and a hollow outlet section having an outlet section connected to the other side of the storage section for discharging the biological fluid and a tightening section for discharging the biological fluid, and is molded from a material having low hardness and high extensibility, so that it can be worn on the body and carried, has a simple configuration, is comfortable to wear, does not leak biological fluid, and can accommodate various amounts of biological fluid to be stored.Furthermore, due to the following configuration unique to the present invention, the following effects unique to the present invention can be achieved.

[0015] The closure body comprises a first clamping arm portion and a second clamping arm portion that clamp the discharge portion to close it, a connecting portion that connects one end of the first clamping arm portion and the second clamping arm portion so that it can be opened and closed freely, and a first closed end portion and a second closed end portion that are arranged at the other end of the first clamping arm portion and the second clamping arm portion and overlap each other inside and outside to form the closure portion in a closed state to form a clamping space.Since the tightening portion of the discharge portion of the container body is clamped and fixed within the clamping space to close the discharge outlet portion, leakage of biological fluids can be reliably prevented, and since the tightening portion of the discharge portion is clamped and fixed immediately before use after the container body is attached to the body, leakage of biological fluids due to elastic deformation of the container body due to external force can be prevented.

[0016] Furthermore, since the first and second closed ends of the closure body are provided with a first locking portion and a second locking portion, respectively, which are arranged opposite each other at corresponding positions, the first locking portion and the second locking portion engage with each other, thereby maintaining the closed state of the closure body, i.e., the clamped and fixed state against the tightening portion of the discharge portion of the container body.

[0017] According to the closure of the invention of claim 2, it comprises a first clamping arm portion and a second clamping arm portion that clamp and close the discharge portion, a connecting portion that connects one end of the first clamping arm portion and the second clamping arm portion so as to be freely opened and closed, and a first closed end portion and a second closed end portion that are arranged at the other end of the first clamping arm portion and the second clamping arm portion and overlap each other inside and outside to form the closure portion in a closed state to form a clamping space.Since the fastening portion of the discharge portion of the container body is clamped and fixed within the clamping space to close the discharge outlet portion, it is possible to reliably prevent leakage of biological fluid and to prevent leakage of biological fluid due to elastic deformation of the container body due to external force.

[0018] Furthermore, since the first and second closed ends of the closure body are provided with a first locking portion and a second locking portion, respectively, which are arranged opposite each other at corresponding positions, the first locking portion and the second locking portion engage with each other, thereby maintaining the closed state of the closure body, i.e., the clamped and fixed state against the tightening portion of the discharge portion of the container body.

[0019] According to the closure of the invention of claim 3, in addition to the effects achieved by the invention of claim 2, the first clamping arm portion has a first pressing portion arranged in a protruding shape toward the clamping space, and the second clamping arm portion has a second pressing portion arranged in a protruding shape toward the clamping space, and by pressing the discharge portion of the container body between the first pressing portion and the second pressing portion, the tightening portion of the discharge portion of the container body is clamped and fixed in the further narrowed portion of the clamping space to close the discharge outlet portion, thereby achieving a closure that more reliably prevents leakage of biological fluids.

[0020] According to the closure of the invention of claim 4, in addition to the effects achieved by the invention of claim 2 or 3, the first locking portion and the second locking portion each have an engaging protrusion having a triangular cross section which engages with each other in a non-return manner in the closed state. Therefore, by simply rotating the first clamping arm portion toward the second clamping arm portion around the connecting portion as the center of rotation, the first closed end portion and the second closed end portion in the closed portion undergo slight elastic deformation while the first locking portion and the second locking portion engage with each other. This means that the closure can be easily placed in the closed state and will not enter an open state unintentionally, and the clamped and fixed state of the discharge portion of the container body against the tightening portion can be reliably maintained.

[0021] According to the closure of the invention of claim 5, in addition to the effects achieved by the invention of claim 2 or 3, the first locking portion and the second locking portion each have an engaging hook piece with an L-shaped cross section which engages with each other in a non-return manner in the closed state, so that the engagement of the engaging hook pieces in the closed state not only prevents the first clamping arm portion and the second clamping arm portion from rotating apart, but also prevents the first locking portion and the second locking portion from moving inward and outward and apart. As a result, the closure can be easily placed in the closed state and will not enter an open state unintentionally, and the clamped and fixed state of the discharge portion of the container body to the tightening portion can be more reliably maintained.

[0022] In addition, because it is molded as a single unit from a flexible material, when the fastening portion of the container body containing the biological fluid is clamped and fixed to close the outlet portion, simply by pressing the connecting portion and the closing portion inward at the same time, the distance between the first clamping arm portion and the second clamping arm portion increases, widening the clamping space and releasing the outlet portion of the container body to allow the biological fluid to be discharged, and the outlet portion is closed and the discharge of the biological fluid is stopped by simply releasing the force pressing the connecting portion and closing portion of the closure body, so that the biological fluid contained in the storage portion can be simply and easily discharged with one hand, and the discharge can be easily interrupted or stopped at any time.

[0023] According to the closure of the invention of claim 6, in addition to the effects achieved by the invention of claim 2 or 3, the first locking portion has an engagement hole and the second locking portion has an engagement protrusion corresponding to the engagement hole, so that the force with which the container body, which is clamped and fixed in the clamping space, tends to bulge outward due to elastic deformation acts to push the engagement protrusion of the first locking portion outward, i.e., the engagement protrusion of the first locking portion acts in a direction such that it engages more deeply with the engagement hole of the second locking portion. As a result, the container body is not opened against the user's will, and the clamped and fixed state of the discharge portion of the container body against the tightening portion can be more reliably maintained.

[0024] In addition, because it is molded as a single unit from a flexible material, when the fastening portion of the container body containing the biological fluid is clamped and fixed to close the outlet portion, simply by pressing the connecting portion and the closing portion inward at the same time, the distance between the first clamping arm portion and the second clamping arm portion increases, widening the clamping space and releasing the outlet portion of the container body to allow the biological fluid to be discharged, and the outlet portion is closed and the discharge of the biological fluid is stopped by simply releasing the force pressing the connecting portion and closing portion of the closure body, so that the biological fluid contained in the storage portion can be simply and easily discharged with one hand, and the discharge can be easily interrupted or stopped at any time.

[0026] First, definitions of terms used to explain the embodiment of the present invention will be given. <Definition of "biofluids"> In this specification, the term "biological fluid" refers to a fluid containing water, such as a solution, suspension or emulsion that is present within a living body or excreted or derived from a living body, such as blood, lymph, tissue fluid, body cavity fluid or other bodily fluid of an animal, or xylem fluid or phloem fluid of a plant, and is used as a concept that particularly includes human urine, menstrual blood or stool.

[0027] <Definition of "hardness"> In this specification, "hardness" refers to a hardness value measured in accordance with "JIS K 6253." Since the material used for the container body of the biological fluid storage container according to the present invention has an extremely low hardness, it is measured using a type E durometer (spring type hardness tester). The higher this measured value, the higher the hardness (i.e., the harder and less likely to deform).

[0028] Therefore, when the container body of a biological fluid storage container is made of a certain material, the lower the hardness of the material, the more flexible the material will be in its physical properties and the more easily it will deform.

[0029] <Definition of "Extensibility"> In this specification, "extensibility" refers to the ability of a single material or composite material to withstand a tensile stress of 70% elongation measured in accordance with "JIS K 6251" when the thickness of the material is T (millimeters) and the tensile stress of the material at 70% elongation is σ (Newtons / square millimeters). 1 / σ×T(millimeter / newton) The higher this value, the greater the elongation per unit pressure, i.e., the easier it is to stretch. Also, a "highly stretchable material" refers to a material that has greater elongation when compared at the same thickness.

[0030] <Definition of "stretchability"> In this specification, the term "elongation" refers to the "elongation" measured in accordance with "JIS K 6251," and is a value expressed as a ratio (unit: %) to the test length before the test.

[0031] When the container body of the biological fluid storage container is made of a single material, the material with higher extensibility has physical properties that make it more likely to expand due to the internal pressure of the stored biological fluid, with the material having a greater elongation per unit pressure.

[0032] Preferred embodiments The container body of the biological fluid storage container of the present invention may have any specific form as long as it is molded from a material having low hardness and high extensibility and at least comprises a hollow storage section for storing biological fluid, a hollow inlet section that is connected to one side of the storage section and has an inlet portion for introducing the biological fluid, and a hollow outlet section that is connected to the other side of the storage section and has an outlet portion for discharging the biological fluid and a tightening portion for discharging the biological fluid.

[0033] Furthermore, the container body can be made of a material having low hardness, for example, an elastomer having an ultra-low hardness of 20 degrees or less.

[0034] Elastomers with a hardness between 0 and 20 degrees are preferably used because they have a hardness lower than the hardness of the skin in many parts of the human body and can reduce the discomfort felt when worn on the human body and carried around. Here, a hardness of 0 degrees means a value below the measurement limit of the measuring device.

[0035] Furthermore, elastomers with a hardness of 0 to 10 degrees are less hard than the skin of the soft parts of the human body, and can therefore be used preferably since they can further reduce the discomfort felt when worn on the human body and carried around.

[0036] A measurement method for obtaining hardness with a definition different from those described above is the hardness obtained by measurement using an Asker hardness tester type F as a durometer. This measurement method can obtain a value of 0 or more for a material with an ultra-low hardness, and it is more preferable to use an elastomer with a hardness of 20 or more and 80 or less in this measurement method.

[0037] An elastomer having an elongation degree of 100 percent or more can be preferably used because the storage portion of the container body expands as it stores biological fluid, thereby increasing the storage capacity.

[0038] In particular, elastomers with an elongation of 2000 percent or more and 3000 percent or less can be used more preferably because they do not substantially restrict the capacity of the storage section and have sufficient elongation to enable long-term use and the storage of large amounts of biological fluids.

[0039] Examples of materials that simultaneously satisfy the above-mentioned hardness and elongation requirements include thermoplastic elastomers (TPEs) such as styrene-based, olefin-based, urethane-based, ester-based, PVC-based, and amide-based TPEs. In particular, KURAIN (registered trademark) manufactured by Kuraray Trading Co., Ltd., which is made of a compound containing 5 times or more paraffin oil in a styrene-based thermoplastic elastomer, can be preferably used.

[0040] In addition, since human skin exhibits a maximum elongation rate (the rate at which it stretches during normal movement) of approximately 70 percent, elastomers with an elongation rate of more than 70 percent are suitable for use because they do not cause pain or a tight sensation to the user when worn on the human body.

[0041] The biological fluid storage container of the present invention is capable of storing various biological fluids, i.e., blood, lymph, tissue fluid, body cavity fluid, and other bodily fluids of animals, or xylem fluid or phloem fluid of plants, as well as water-containing fluids such as solutions, suspensions, and emulsions that are present within a living body or that flow out, excrete, or are derived from a living body, and is particularly capable of storing human urine, menstrual blood, or faeces.

[0042] The closure of the present invention comprises a first clamping arm portion and a second clamping arm portion that clamp and close the discharge portion, a connecting portion that connects one end of the first clamping arm portion and the second clamping arm portion so as to be freely opened and closed, and a first closed end portion and a second closed end portion that are arranged at the other end of the first clamping arm portion and the second clamping arm portion and overlap each other inside and outside to form the closure portion in a closed state to form a clamping space, and the first closed end portion and the second closed end portion have first locking portions and second locking portions that are respectively arranged at corresponding positions opposite each other, and are integrally molded from a material having a hardness greater than that of the container body, so long as it reliably prevents leakage of the biological fluid, facilitates the discharge operation of the biological fluid, and prevents leakage of the biological fluid due to elastic deformation of the container body due to external force, any specific embodiment is acceptable.

[0043] The material from which the closure is made may be the same as or different from the material from which the container body is made, and various thermoplastic elastomers, such as urethane rubber or soft polyvinyl chloride, or various thermosetting elastomers, such as silicone rubber, can be used.

[0044] In particular, the material of the closure of Example 1 of the present invention can be suitably made of a material having a bending elasticity of 5000 MPa or less and a tensile elongation of 30 percent or more, and more specifically, can be made of polyethylene, polypropylene, ABS, acrylic resin, etc.

[0045] In addition, as the material of the closure body according to the second and third embodiments of the present invention, a material having a hardness higher than that of the discharge part, for example, a flexibility of a hardness of 20A or more and 90A or less, can be suitably used, and more specifically, the closure body can be made of natural rubber, synthetic rubber, silicone rubber, various thermoplastic elastomers, various thermosetting elastomers, etc.

[0046] Furthermore, if the hardness of the material forming the closure is greater than the hardness of the material forming the container body, the amount of deformation of the closure will be relatively small compared to the amount of deformation of the container body in the closed state, and when the fastening portion of the discharge section of the container body is clamped and fixed to close the discharge outlet portion, leakage of biological fluids can be reliably prevented and leakage of biological fluids due to elastic deformation of the container body due to external forces can be prevented. EXAMPLES

[0047] A biological fluid storage container 100 according to a first embodiment of the present invention will now be described with reference to FIGS.

[0048] Here, Figure 1 is a schematic diagram showing a state in which a user wears a biological fluid storage container according to the present invention on their penis, Figure 2A is a schematic front view showing a container body of a biological fluid storage container according to the first embodiment of the present invention, Figure 2B is a schematic side view showing a container body of a biological fluid storage container according to the first embodiment of the present invention, Figure 3 is a schematic oblique view showing a biological fluid storage container according to the present invention, Figure 4A is a schematic oblique view showing a closure body according to the first embodiment of the present invention, Figure 4B is a schematic plan view showing a closure body according to the first embodiment of the present invention, Figure 5 is a VV cross-sectional view in Figure 4B, and Figure 6 is a VI-VI cross-sectional view in Figure 4B.

[0049] The biological fluid storage container 100 in this embodiment is a urine storage container, and is composed of a container body 110 and a closure body 120. As shown in FIG. 1, the penis P, which serves as the excretory organ of a human body B, is inserted into the container and is naturally held within clothing C worn by the human body B.

[0050] <Container body configuration> As shown in Figures 2A to 3, the container body 110 is composed of a storage section 111, an inlet section 112, a discharge section 113, a guide section 114, and a check valve section 115, and each section is molded integrally from a material having low hardness and high extensibility.

[0051] The material with low hardness and high elongation used in this embodiment is a thermoplastic elastomer, more specifically, KURAIN (registered trademark) manufactured by Kuraray Trading Co., Ltd., which is made of a compound containing 5 times or more paraffin oil in a styrene-based thermoplastic elastomer (TPS: Thermoplastic Styrenic Elastomer), and is a material with a hardness of 10 degrees or less and an elongation of 2000 percent or more.

[0052] <Containment section configuration> The storage section 111 is hollow and forms a storage space AS for storing urine as a biological fluid, has a flat shape with a bulging portion 111a that bulges in the left and right direction, and has a storage space bottom portion 111b that forms the lowest position of the storage space AS when in use.

[0053] Although the thickness dimension TA of the accommodation portion 111 varies depending on the portion, the thickness dimension of the bulging portion 111a is smaller than the thickness dimension TA of the other portions. Therefore, the thin portion 111aa where the thickness dimension TA of the accommodation portion 111 is the smallest is located in the bulging portion 111a.

[0054] In this embodiment, the thickness dimension TA of the housing portion 111 at the thin portion 111aa is about 2 mm.

[0055] In this embodiment, the container portion 111, the introduction portion 112, the discharge portion 113, the induction portion 114 and the check valve portion 115 are integrally molded from a thermoplastic elastomer having low hardness and high extensibility.

[0056] <Introduction Structure> The introduction part 112 is hollow and includes an introduction port part 112 b for introducing urine, and an introduction channel IC is formed inside a cylindrical attachment part 112 a . The introduction part 112 is connected to one side of the storage part 111 .

[0057] In this embodiment, it is assumed that the user's penis P is inserted into the introduction passage IC, and the cross-sectional shape of the introduction passage IC is circular.

[0058] In this embodiment, the thickness dimension TI of the introduction portion is about 5 mm, and the inner diameter dimension ID of the introduction passage is about 10 mm.

[0059] <Exhaust section configuration> The discharge part 113 is hollow and includes a discharge port part 113b for discharging urine, and a discharge path OC is formed inside the fastening part 113a, and communicates with the other side of the storage part 111.

[0060] In this embodiment, the thickness dimension TO of the discharge portion varies depending on the location, but is about 3 mm or more and about 5 mm or less.

[0061] <Configuration of Guiding Part 114> The guide portion 114 is formed in a hollow shape so as to protrude toward the storage space AS in the storage portion 111 at a portion where the storage portion 111 and the introduction portion 112 communicate with each other, and guides the urine in the guide space GS into the storage portion 111.

[0062] The thickness dimension TG of the guide portion 114 differs depending on the location, but in this embodiment, is about 3 mm or more and about 5 mm or less.

[0063] The guide portion 114 forms a guide space GS having a length dimension LG of the guide portion by a support portion 114a that supports the check valve portion 115. In this embodiment, the length dimension LG of the guide portion is about 20 mm.

[0064] In this embodiment, it is assumed that the user's glans will be inserted and positioned within the guidance space GS, so a large diameter portion 114aa is formed approximately in the center of the length of the support portion 114a which forms the guidance space GS, and a small diameter portion 114ab is formed at a position corresponding to the bottom portion 111b of the storage space of the storage portion 111.

[0065] In other words, the storage space bottom portion 111ab of the storage portion 111 is disposed at a position corresponding to the small diameter portion 114ab, and this small diameter portion 114ab is located closer to the introduction portion 112 than the large diameter portion 114aa of the support portion 114a of the guide portion 114.

[0066] <Check valve configuration> The check valve portion 115 is formed at the tip of the guide portion 114 to protrude toward the storage portion 111 in order to prevent urine from flowing back, and has a pair of valve portions 115a that are spaced apart and positioned close to each other, facing each other toward the storage portion 111. Since a pair of valve portions 115a are arranged facing each other at a distance from each other in close proximity, when no urine is contained in the storage portion 111, the check valve portion 115 has a valve opening VO that is open in the shape of an oval slit.

[0067] As described above, container body 110 is configured by integrally molding the following from a styrene-based thermoplastic elastomer having low hardness and high extensibility: hollow storage section 111 forming storage space AS for storing urine; hollow introduction section 112 which is provided with introduction port portion 112b which communicates with one side of storage section 111 and introduces urine, thereby forming introduction path IC; hollow discharge section 113 which is provided with outlet portion 113b which communicates with the other side of storage section 111 and discharges urine, thereby forming discharge path OC; hollow guide section 114 which protrudes toward storage section 111 at the site where storage section 111 and introduction section 112 communicate with each other and guides urine into storage section 111; and check valve portion 115 which is formed in guide section 114 and prevents urine from flowing back.

[0068] <Configuration of the Closure> On the other hand, as shown in Figures 4A to 6, the closure body 120 is composed of a thin plate-like first clamping arm portion 121 and a thin plate-like second clamping arm portion 122 that clamp and close the fastening portion 113a of the container body 110 that constitutes the biological fluid storage container 100, a thin plate-like connecting portion 123 that connects one connecting side end of each of the first clamping arm portion 121 and the second clamping arm portion 122 so as to be able to open and close freely, and a thin plate-like first closed end portion 124a and a thin plate-like second closed end portion 124b that are arranged perpendicular to the other opening and closing side ends of the first clamping arm portion 121 and the second clamping arm portion 122 to constitute the closing portion 124.

[0069] In addition, the first closed end portion 124a and the second closed end portion 124b overlap each other on the inside and outside with respect to the sandwiching space ES in the closed state to form the closing portion 124.

[0070] The first locking portion 124aa of the first closed end portion 124a and the second locking portion 124ba of the second closed end portion 124b are respectively positioned opposite each other in corresponding positions in the closed state, and in the closed state, the first locking portion 124aa and the second locking portion 124ba engage with each other to maintain the closed state of the closure body 120.

[0071] In this embodiment, the first locking portion 124aa and the second locking portion 124ba each have an engaging protrusion having a triangular cross section, and are configured to engage with each other in a non-return manner in the closed state.

[0072] In addition, the first clamping arm portion 121 has a first pressing portion 121a that protrudes in a ridge-like manner toward the clamping space ES and a first operating rib 121b that protrudes in a ridge-like manner toward the outside, and the second clamping arm portion 122 has a second pressing portion 122a that protrudes in a ridge-like manner toward the clamping space ES and a second operating rib 122b that protrudes in a ridge-like manner toward the outside, and is configured to press the fastening portion 113a of the discharge portion 113 of the container body 110 between the first pressing portion 121a and the second pressing portion 122a.

[0073] The closure body 120 is integrally formed in its respective parts from polyethylene, which is a material having a greater hardness than the material of the container body 110 .

[0074] <How to use> Since the introduction portion 112 of the container body 110 is integrally molded from a thermoplastic elastomer having low hardness and high extensibility, the user can easily enlarge and open the introduction port portion 112b by applying force to turn the attachment portion 112a over with both hands.

[0075] First, the discharge part 113 is temporarily closed by the closing body 120, and then the introduction port part 112b is opened widely, and the user's penis P is inserted into the introduction part 112, and then the attachment part 112a is opened and released, so that it is attached to the penis P.

[0076] Here, with the first clamping arm portion 121 and the second clamping arm portion 122 of the closure body 120 in a released state, the clamping portion 113a of the discharge portion 113 of the container body 110 is positioned so as to be clamped from the side so as to fit within the clamping space ES of the closure body 120.

[0077] Thereafter, the closure body 120 is grasped by placing fingers on the first operating rib 121b and the second operating rib 122b, and the first clamping arm portion 121 and the second clamping arm portion 122 are rotated in a direction in which they approach each other around the connecting portion 123 as the center of rotation, thereby reliably closing the closure body 120 with an easy and simple operation without the fingers slipping and the closure body 420 being dropped.

[0078] At this time, the first closed end portion 124a arranged on the open end side of the first clamping arm portion 121 and the second closed end portion 124b arranged on the open end side of the second clamping arm portion 122 overlap each other with the first closed end portion 124a on the outside and the second closed end portion 124b on the inside based on the clamping space ES to form the closing portion 124.

[0079] In the closing portion 124, the first locking portion 124aa and the second locking portion 124ba engage with each other in a non-return manner while the first closed end portion 124a and the second closed end portion 124b undergo slight elastic deformation, thereby maintaining the closure body 120 in a closed state.

[0080] When the closure body 120 is closed by the above process, the first clamping arm portion 121 and the second clamping arm portion 122 are arranged opposite and approximately parallel to each other, as shown by the dashed lines in Figure 4B, and further, the connecting portion 123 and the closing portion 124 are juxtaposed opposite and approximately parallel to each other to form a rounded rectangular clamping space ES, and as shown in Figure 3, the clamping portion 113a of the discharge portion 113 of the container body 110 is clamped and fixed within this clamping space ES.

[0081] Here, since the first pressing portion 121a of the first clamping arm portion 121 and the second pressing portion 122a of the second clamping arm portion 122 are arranged in corresponding positions facing each other, the clamping and fixing force when the closure body 120 is in the closed state is concentrated on the first pressing portion 121a and the second pressing portion 122a, and the fastening portion 113a of the discharge portion 113 of the container body 110 is tightly clamped from both sides.

[0082] In addition, the discharge direction width dimension Wp of the first pressing portion 121a and the second pressing portion 122a is set to be longer than the discharge direction width dimension of the discharge passage OC when the fastening portion 113a of the discharge section 113 of the container body 110 is crushed from the front-to-rear direction, as shown in Figure 5, thereby blocking the discharge passage OC in the width direction and reliably closing the container body 110.

[0083] Also, as shown in FIG. 6, the first pressing portion 121a and the second pressing portion 122a each have an L-shaped cross section to ensure a sufficient height dimension in the discharge direction, and press the fastening portion 113a of the discharge section 113 of the container body 110 over a sufficient distance in the discharge direction to close it.

[0084] Furthermore, since the height dimension Hp of the first pressing portion 121a and the second pressing portion 122a is set to less than half the height dimension Ha of the first clamping arm portion 121 and the second clamping arm portion 122, respectively, the clamping force during closing is concentrated at the area where the first pressing portion 121a and the second pressing portion 122a press the tightening portion 113a.

[0085] By following the above procedure, when the fastening portion 113a of the discharge section 113 of the container body 110 is placed in the clamping space ES and the closure body 120 is put into the closed state, the closure body 120 tightens the fastening portion 113a from the outside, thereby closing the discharge path OC near the discharge opening portion 113b, resulting in the installed state shown in Figure 1.

[0086] When urination is initiated with the biological fluid storage container 100 attached to the penis P as shown in FIG. 1, the valve opening VO formed by the pair of valve membrane portions 115a of the check valve portion 115 is in an open state at the stage when urination begins, so that even when the urine pressure is low, the urine is reliably guided into the storage portion 111 and stored in the storage space AS.

[0087] When discharging the urine contained in the storage section 111, the biological fluid storage container 100 is attached to the penis P, and the engagement between the first clamping arm section 121 and the second clamping arm section 122 of the closure body 120 is released.

[0088] By this operation, the first clamping arm portion 121 and the second clamping arm portion 122, which clamp and fix the fastening portion 113a of the discharge portion 113 from the outside, rotate in the opening direction around the connecting portion 123 and separate, releasing the discharge path OC inside the discharge portion 113, which is molded from a thermoplastic elastomer having low hardness and high extensibility, and urine is discharged from the discharge opening portion 113b.

[0089] When the first clamping arm portion 121 and the second clamping arm portion 122 of the closing body 120 are engaged again, the closing body 120 tightens the tightening portion 113a from the outside, thereby closing the discharge passage OC near the discharge opening portion 113b again. EXAMPLES

[0090] Next, a closing body 220 according to a second embodiment of the present invention will be described with reference to FIGS. 7A to 9. FIG.

[0091] Here, FIG. 7A is a schematic perspective view showing a closing body according to the second embodiment of the present invention, FIG. 7B is a schematic plan view showing a closing body according to the second embodiment of the present invention, FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 7B, and FIG. 9 is a cross-sectional view taken along line IX-IX in FIG. 7B.

[0092] In the drawings relating to this embodiment, if there is a configuration corresponding to the first embodiment, the numbers in the 100s will be changed to numbers in the 200s, and if the configuration and method of use are similar to those of the first embodiment, detailed explanations will be omitted.

[0093] <Configuration of the Closure> The configuration of the closing body 220 according to this embodiment is different from the configuration of the closing body 120 according to the first embodiment in the following points.

[0094] First, as shown in Figures 7A to 9, in this embodiment, the first clamping arm portion 221, the second clamping arm portion 222, the connecting portion 223, and the first closed end portion 224a and the second closed end portion 224b constituting the closing portion 224 are each configured in the shape of a thick plate.

[0095] As shown in FIGS. 7A and 7B, in this embodiment, the first locking portion 224aa and the second locking portion 224ba each include an engaging hook piece having an L-shaped cross section.

[0096] Furthermore, as shown in FIG. 9, in this embodiment, the first pressing portion 221a and the second pressing portion 222a each have a rectangular cross section with rounded corners.

[0097] In addition, each part of the closure body 220 is integrally molded from a thermoplastic elastomer having a hardness of 30A, which is a flexible material having a hardness greater than that of the container body 110 .

[0098] <How to use> The method of using the closing body 220 according to this embodiment differs from the method of using the closing body 120 according to the first embodiment in the following points.

[0099] First, when the first clamping arm portion 221 and the second clamping arm portion 222 are rotated in a direction to approach each other around the connecting portion 223 as the rotation center to enter a closed state, the first closed end portion 224a is elastically deformed outward and the second closed end portion 224b is elastically deformed inward based on the clamping space ES, thereby engaging the hook piece of the first locking portion 224aa with the hook piece of the second locking portion 224ba.

[0100] In addition, when discharging the urine contained in the storage section 111, while the biological fluid storage container 100 is still attached to the penis P, the connecting section 223 and the closing section 224 of the closure body 220 are pinched inward with the index finger and thumb of one hand to apply force.

[0101] This operation causes the first clamping arm portion 221 and the second clamping arm portion 222, which clamp and fix the fastening portion 113a of the discharge portion 113 from the outside, to expand due to the elasticity of the flexible material, releasing the discharge path OC inside the discharge portion 113 of the container body 110, which is molded from a thermoplastic elastomer having low hardness and high extensibility, and allowing urine to be discharged from the discharge opening portion 113b.

[0102] When the application of force with the index finger and thumb is stopped, the first clamping arm portion 221 and the second clamping arm portion 222 of the closure body 220 tighten the tightening portion 113a from the outside again due to the restoring force of the elastic deformation, thereby closing the discharge path OC near the discharge opening portion 113b and interrupting or terminating the discharge of urine. EXAMPLES

[0103] Further, a closing body 320 according to a third embodiment of the present invention will be described with reference to FIGS. 10A to 12. FIG.

[0104] Here, Figure 10A is a schematic oblique view showing a closing body according to the third embodiment of the present invention, Figure 10B is a schematic plan view showing a closing body according to the third embodiment of the present invention, Figure 11 is a cross-sectional view taken along line XI-XI in Figure 10B, and Figure 12 is a cross-sectional view taken along line XII-XII in Figure 10B.

[0105] In the drawings relating to this embodiment, when there is a configuration corresponding to the first or second embodiment, the numbers in the 100s or 200s are changed to numbers in the 300s, and when the configuration and method of use are similar to those of the first or second embodiment, detailed explanations are omitted.

[0106] <Configuration of the Closure> The configuration of the closing body 320 according to this embodiment is different from the configurations of the closing body 120 according to the first embodiment and the closing body 220 according to the second embodiment in the following points.

[0107] First, as shown in Figures 10A to 12, in this embodiment, first clamping arm portion 321, second clamping arm portion 322, connecting portion 323, first closed end portion 324a and second closed end portion 324b which constitute closing portion 324 are each configured in the shape of a thick plate, and in particular first closed end portion 324a has an especially thick block configuration in order to form an engagement hole of first locking portion 324aa described below.

[0108] That is, as shown in FIGS. 10A to 11, in this embodiment, the first locking part 324aa has a fitting hole, and the second locking part 324ba has a fitting protrusion corresponding to this fitting hole.

[0109] The closure 320 is integrally molded from silicone rubber having a hardness of 50A, which is a flexible material having a hardness greater than that of the container body 110 .

[0110] <How to use> The method of using the closing body 320 according to this embodiment differs from the methods of using the closing body 120 according to the first embodiment and the closing body 220 according to the second embodiment in the following points.

[0111] When the first clamping arm portion 321 and the second clamping arm portion 322 are rotated in a direction approaching each other around the connecting portion 323 as the rotation center to enter a closed state, the first closed end portion 324a is elastically deformed outward and the second closed end portion 324b is elastically deformed inward based on the clamping space ES, so that the mating protrusion of the second locking portion 324ba is fitted into the mating hole of the first locking portion 324aa.

[0112] With this operation, the mating protrusion of the second locking portion 324ba fits into the mating hole of the first locking portion 324aa from the inside, so that the force of the container body 110, which is clamped and fixed within the clamping space ES, tending to bulge outward due to elastic deformation acts outward on the mating protrusion of the second locking portion 324ba, i.e., acts in a direction that causes the mating protrusion to fit deeper into the mating hole of the first locking portion 324aa, thereby reliably maintaining the closed state of the closure body 320. EXAMPLES

[0113] As shown in FIG. 13, the closing body 420 in this embodiment is configured with a thin plate-shaped first clamping arm portion 421 and a thin plate-shaped second clamping arm portion 422, a thin plate-shaped connecting portion 423 that connects one connecting end portion of each of the first clamping arm portion 421 and the second clamping arm portion 422 so as to be able to open and close freely, and a thin plate-shaped first closing end portion 424a and a thin plate-shaped second closing end portion 424b that are arranged perpendicular to the other opening and closing end portions of the first clamping arm portion 421 and the second clamping arm portion 422 to constitute a closing portion 424.

[0114] Similarly to the first embodiment, the first closed end portion 424a and the second closed end portion 424b overlap each other on the inside and outside with respect to the sandwiching space ES in the closed state to form a closing portion 424.

[0115] The first locking portion 424aa of the first closed end portion 424a and the second locking portion 424ba of the second closed end portion 424b are respectively positioned opposite each other in corresponding positions in the closed state, and in the closed state, the first locking portion 124aa and the second locking portion 124ba engage with each other to maintain the closed state of the closure body 120.

[0116] In this embodiment, the first locking portion 424aa and the second locking portion 424ba each have an engaging protrusion having a triangular cross section, and are configured to engage with each other in a non-return manner in the closed state.

[0117] The closure body 420 is integrally formed in its respective parts from polyethylene, which is a material having a greater hardness than the material of the container body 110 .

[0118] In this embodiment, unlike the first embodiment, the first clamping arm portion 421 and the second clamping arm portion 422 do not have a pressing portion that protrudes in a ridge-like shape toward the clamping space ES, but instead have a first operating rib 421b and a second operating rib 422b that protrude in a ridge-like shape toward the outside, and further have a first engagement protrusion 421c and a second engagement protrusion 422c that protrude in a hemispherical shape toward the clamping space ES near the connecting portion 423, and are configured to press the fastening portion 113a of the discharge portion 113 of the container body 110 between the flat inner surface of the first clamping arm portion 421 and the flat inner surface of the second clamping arm portion 422.

[0119] When the closure body 420 of this embodiment clamps and closes the discharge portion 113 of the container body 110, the first clamping arm portion 421 and the second clamping arm portion 422 do not have a pressing portion that protrudes in a protruding manner toward the clamping space ES, and therefore the discharge portion 113 of the container body 110 is clamped by the inner flat surfaces of the first clamping arm portion 421 and the second clamping arm portion 422.This makes the external force applied to the discharge portion 113 of the container body 110 uniform, and a uniform closed state with a small amount of deformation of the container body 110 can be achieved, making it possible to more reliably prevent leakage of biological fluid due to elastic deformation of the container body due to external force.

[0120] In addition, the first clamping arm portion 421 and the second clamping arm portion 422 of the closure body 420 are provided with a first engagement protrusion 421c and a second engagement protrusion 422c which protrude hemispherically toward the clamping space ES near the connecting portion 423. Therefore, when the closure body 420 clamps and closes the discharge portion 113 of the container body 110 and then the engagement between the first clamping arm portion 421 and the second clamping arm portion 422 is released to discharge the urine contained in the storage portion 111, the first engagement protrusion 421c and the second engagement protrusion 422c are engaged in a state in which they are biting into the discharge portion 113 of the container body 110, thereby preventing the closure body 420 from falling off from the container body 110.

[0121] Furthermore, since the first clamping arm portion 421 and the second clamping arm portion 422 of the closure body 420 are respectively provided with a first operating rib 421b and a second operating rib 422b that protrude outward in a protruding manner, when opening or closing the closure body 420, the operator places his or her fingers on the first operating rib 421b and the second operating rib 422b to operate it, thereby achieving a reliable opening and closing operation without the operator's fingers slipping and causing the closure body 420 to be dropped.

[0122] In addition, even if the first clamping arm portion 421 and the second clamping arm portion 422 of the closure body 420 are configured in a thin plate shape, the first operating rib 421b and the second operating rib 422b are provided, thereby increasing the strength against bending and preventing the first clamping arm portion 421 and the second clamping arm portion 422 from deforming so as to bulge due to the reaction force received outward from the container body 110 when clamping the discharge portion 113 of the container body 110.
