Description

[Technical Field]

[0001] The present invention relates to a mixing vessel for mixing fluids or semi-fluids contained in a plurality of vessels. [Background technology]

[0002] For example, Patent Document 1 describes a cap for mixing two liquids. This cap for mixing two liquids has a configuration in which the sealing wall of a sub-container containing an additive liquid is broken by the tip of a first cutter provided on the bottom wall of the inner tube of the cap body. The additive liquid flows down into the main container to which the cap is attached and is mixed with the content liquid inside the main container. The first cutter used here has a tapered cross shape at the top end. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4031276 Summary of the Invention [Problem to be solved by the invention]

[0004] Although a cutting blade with a tapered cross-shaped upper end, like the first cutter, can penetrate and break the seal wall of the target, it is difficult to break a wide area at once. Therefore, there is a risk that the additive in the sub-container will flow down firmly into the main container, preventing reliable mixing of the content liquid and the additive liquid in the main container. [Means for solving the problem]

[0005] A mixing container for solving the above problem comprises a container body having a cylindrical main body accommodating portion with a main body opening, and a lid member having a cylindrical lid accommodating portion with an outlet, wherein the outlet of the lid accommodating portion is blocked by a film when the lid accommodating portion contains a second agent, and when the main body accommodating portion contains a first agent, the lid accommodating portion is fitted into the main body opening from the side where the film is arranged, thereby blocking the main body opening with the lid member, and the main body accommodating portion has a protrusion for breaking the film, the protrusion extending from the inside of the main body accommodating portion toward the main body opening, and the tip surface of the protrusion extending in two directions that intersect with each other, and the plane including the two directions includes a plane parallel to the plane including the main body opening.

[0006] According to the above configuration, the tip surfaces extending in two mutually intersecting directions pierce the film, so that when the lid housing is fitted, the area of the film that is broken at once tends to expand, thereby improving mixability.

[0007] In the mixing container, the tip surface of the protruding piece may have a comb-like shape when viewed from a viewpoint facing the main body opening. According to the above configuration, the comb-like tip surface has a surface portion extending in one direction and another surface portion extending in a different direction from the first surface portion, so that the portion of the film that is broken at one time can be expanded.

[0008] In the above-mentioned mixing container, the main body accommodating portion comprises a cylindrical portion having the main body opening and a rectangular cylindrical portion located in the optical path of optical inspection, the rectangular cylindrical portion comprises a first bottom of the main body accommodating portion, the cylindrical portion comprises a second bottom extending from the opening of the rectangular cylindrical portion to the outside of the opening, the protruding piece comprises a first fracture wall and a second fracture wall, the first fracture wall is erected at the second bottom so as to follow the inner surface of the lid accommodating portion, and the second fracture wall is erected at the second bottom so as to extend from the first fracture wall toward the inside of the cylindrical portion.

[0009] According to the above configuration, because the first rupture wall has a shape that conforms to the inner circumferential surface of the lid accommodating portion, the portion of the film that is ruptured at one time can be spread along the inner circumferential surface of the lid accommodating portion. Because the second rupture wall extends from the first rupture wall toward the inside of the cylindrical portion, the portion of the film that is ruptured at one time can be spread from the inner circumferential surface of the lid accommodating portion toward the inside of the lid accommodating portion. Furthermore, the tip surface of the protrusion can guide the second agent that flows out from the ruptured film toward the inside of the cylindrical portion and further toward the rectangular tubular portion. This also makes it easier to accommodate a mixed agent in a rectangular tubular portion used for optical inspection.

[0010] In the mixing container, the second bottom of the cylindrical portion may be configured to be inclined downward toward the opening of the rectangular cylindrical portion. According to the above configuration, since the bottom of the cylindrical portion is inclined downward toward the opening of the rectangular cylindrical portion, the second agent that flows out from the lid housing portion along the protruding piece can be efficiently guided to the rectangular cylindrical portion.

[0011] In the above-mentioned mixing container, the main body accommodating portion has a cylindrical main body peripheral wall into which the lid accommodating portion is fitted, and at least one of the inner peripheral surface of the main body peripheral wall and the outer peripheral surface of the lid accommodating portion, which are pressed against each other, may be configured to have a vent groove that allows the air inside the main body accommodating portion to escape to the outside when the lid accommodating portion is fitted inside the main body peripheral wall.

[0012] According to the above configuration, the vent groove allows the air inside the main body housing to escape to the outside when the lid housing is fitted inside the main body peripheral wall. This allows the lid housing to be fitted inside the main body peripheral wall smoothly. Furthermore, the main body housing is prevented from becoming pressurized when the lid housing is fitted inside the main body peripheral wall. This prevents the second agent from becoming difficult to flow out of the lid housing.

[0013] In the mixing container, the vent groove may extend from the main body opening to a position closer to the bottom of the main body accommodating portion than the tip of the protruding piece. According to this configuration, the vent groove allows internal air to escape to the outside even after the tip of the protruding piece breaks the film. This prevents an increase in internal pressure in the main body accommodating portion even if the lid accommodating portion is further fitted after the film breaks.

[0014] In the above mixing container, the main body peripheral wall may be the main body inner peripheral wall, and the outer peripheral side of the main body inner peripheral wall may be provided with a main body outer peripheral wall that forms a double structure with the main body inner peripheral wall, the main body inner peripheral wall is a peripheral wall into which the lid accommodating part is fitted, and a groove that communicates with the main body accommodating part via the vent groove may be provided between the main body inner peripheral wall and the main body outer peripheral wall when the lid accommodating part is fitted into the main body inner peripheral wall.

[0015] According to the above configuration, when the lid housing is fitted into the main body inner peripheral wall, the air inside the main body inner peripheral wall flows through the vent groove into the groove between the main body inner peripheral wall and the main body outer peripheral wall. Even if the first or second agent leaks out along with the air inside the main body housing, the leaked first or second agent accumulates in the groove. This allows the air inside the main body housing to escape, suppressing an increase in internal pressure in the main body housing, while also suppressing leakage of the first or second agent from the main body housing. [Effects of the Invention]

[0016] According to the present invention, the mixability of the first and second parts can be improved. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] A mixing vessel to which the present invention is applied will be described below with reference to the drawings. [Diagnostic kit] 1 shows a diagnostic kit for in vitro diagnostic medicines that uses a mixing container to which the present invention is applied. This diagnostic kit includes a container 1, a nozzle cap 2 that closes the container 1, and a mixing container 3. A first agent 6, such as a drug or physiological saline, is stored in the container 1. The container 1 is then closed with a film 1a, such as an aluminum seal, while the first agent 6 is stored therein. The nozzle cap 2 includes a cap portion 2a that closes the opening of the container 1 by a screw action, and a nozzle portion 2b that protrudes from the cap portion 2a.

[0019] For testing, with film 1a peeled off, a sample such as blood or a nasopharyngeal swab is collected with a swab or the like, and the swab is immersed in first agent 6. Next, the opening of container 1 is closed with nozzle cap 2. The sample is then dropped into container 1, which contains first agent 6. The sample may be one for testing water quality, bacteria, drugs, or food allergens.

[0020] The mixing container 3 includes a container body 11 into which the first agent 6a mixed with the specimen from the container 1 is poured, and a lid member 31 in which the second agent 7 is stored. The first agent 6a stored in the container 1 is poured into the container body 11 through the nozzle portion 2b. The container body 11 is attached to the optical inspection device 4 (see FIG. 2) and placed in the optical path of the measurement light. The blank value of the first agent 6a is measured by irradiating the measurement light. Thereafter, the container body 11 is removed from the optical inspection device 4. Then, as shown in FIG. 2, the container body 11 is closed with the lid member 31, and at the same time, the second agent 7, such as a chemical solution, stored in the lid member 31 flows down into the container body 11. As a result, the first agent 6a and the second agent 7 are mixed in the container body 11. Then, the mixing container 3 is attached to the optical inspection device 4 again, and the characteristic value of the mixture 8 (see FIG. 2) is measured by irradiating the measurement light.

[0021] [Mixing container] As shown in FIG. 2, the mixing container 3 includes a container body 11 and a cover member 31. The first agent 6a is poured from the container 1 into the container body 11 while the container body 11 is not closed with the lid member 31. After the first agent 6a is poured, the container body 11 is closed with the lid member 31. The lid member 31 stores the second agent 7. When the container body 11 is closed with the lid member 31, the second agent 7 simultaneously flows down into the container body 11, and a mixture 8 in which the first agent 6a and the second agent 7 are mixed is produced.

[0022] The first agent 6a is poured into the container body 11 through the body opening 17, and then the container body 11 is closed with the lid member 31. Therefore, the container body 11 is provided with a support piece 21 that functions as a support for allowing the container body 11 to stand on its own and as a guide for attaching the container body 11 to the attachment portion of the optical inspection device 4. Furthermore, the mixing container 3 is shaken to mix the first agent 6a and the second agent 7. Therefore, the lid member 31 is firmly attached to the container body 11 when the container body 11 is closed so that the mixed agent 8 does not leak.

[0023] [Container body] 3 and 4, the container body 11 is a molded product made of a light-transmitting resin with excellent light-transmittance, such as acrylic resin, polystyrene, polycarbonate, or polypropylene, or a transparent resin, glass, etc. Note that at least the width surface 15b of the rectangular tubular portion 15 onto which the measuring light described below is irradiated needs to be made of a light-transmitting material.

[0024] The container body 11 comprises a main body inner peripheral wall 12, which is the main body peripheral wall, and a main body outer peripheral wall 13. The container body 11 is also divided into an upper and lower portion, with the upper portion comprising a cylindrical portion 14 and the lower portion comprising a rectangular tubular portion 15. The upper portion is formed by a double-wall structure consisting of the main body inner peripheral wall 12 and the main body outer peripheral wall 13. The cylindrical portion 14 is a space formed inside the main body inner peripheral wall 12. The cylindrical portion 14 and the rectangular tubular portion 15 together form a main body storage portion 16.

[0025] The upper surface of the container body 11 is formed by a body opening 17. The body opening 17 is an opening formed inside the body outer peripheral wall 13. Of the body inner peripheral wall 12 and body outer peripheral wall 13 facing the body opening 17, the tip of the body inner peripheral wall 12 is located at a higher position than the tip of the body outer peripheral wall 13. Furthermore, a bottomed annular groove 18 is formed in the space between the body inner peripheral wall 12 and the body outer peripheral wall 13. The body outer peripheral wall 13 is a continuous outer peripheral wall extending from the upper to lower portions, with the upper portion having a cylindrical shape and the lower portion constituting a rectangular tubular portion 15. The body outer peripheral wall 13 also has an inclined portion 22 between the upper and lower portions.

[0026] The tip of the outer circumferential wall 13 of the main body is provided with a pair of connecting pieces 19 at opposing positions for connecting the lid member 31. A pair of locking pieces 35 of the lid member 31 is inserted between the pair of connecting pieces 19, and the pair of locking pieces 35 are locked with the connecting pieces 19. As a result, the lid member 31 is integrated with the container main body 11 in a state where the main body opening 17 is closed.

[0027] The lower part of the main body outer peripheral wall 13 is a part that constitutes the rectangular tubular portion 15. The rectangular tubular portion 15 has opposing length surfaces 15a and opposing width surfaces 15b (see FIG. 2). The pair of width surfaces 15b are located between the pair of length surfaces 15a and have a smaller area than the length surfaces 15a. Support pieces 21 are provided at each corner formed by the width surfaces 15b and the length surfaces 15a. The support pieces 21 are perpendicular to the width surfaces 15b and extend in the vertical direction. The support pieces 21 protrude below the rectangular tubular portion 15 so as to form a gap below the bottom (first bottom) of the rectangular tubular portion 15. In other words, the lower ends of the four support pieces 21 form support legs and are at the same height.

[0028] One of the opposing length surfaces 15a is provided with a positioning piece 21a. The positioning piece 21a is also a protrusion that extends in the vertical direction, and its lower end is at the same height as the lower end of the support piece 21. The support piece 21 also functions as a guide by engaging with a guide rail of the mounting portion when mounted to the mounting portion of the optical inspection device 4. The positioning piece 21a functions to position the mounting position by engaging with a recessed groove of the mounting portion, and also functions as a part to prevent erroneous insertion into the mounting portion. The pair of width surfaces 15b of the rectangular tubular portion 15 are the surfaces onto which the measurement light is irradiated when mounted to the mounting portion, so they are not provided with support pieces 21 or positioning pieces 21a and are made up of flat surfaces with excellent light transmittance.

[0029] In the outer peripheral wall 13 of the main body, the boundary between the upper and lower parts forms an inclined portion 22 that slopes downward from the outside to the inside. The inner surface of the inclined portion 22, which is also the upper surface, forms the bottom (second bottom) of the cylindrical portion 14. The opening surrounded by the inner surface of the inclined portion 22 is the upper opening of the rectangular tubular portion 15 and connects to the cylindrical portion 14.

[0030] Inside the container body 11, a main body inner peripheral wall 12 is erected on the inner surface of the inclined portion 22, and the main body inner peripheral wall 12 defines a cylindrical portion 14 on its inner side. The inner surface of the main body inner peripheral wall 12 is provided with a vent groove 23 configured as a straight groove with a bottom extending in the vertical direction. The vent groove 23 is provided on the upper side of a pair of width surfaces 15b that define the rectangular tubular portion 15. A plurality of vent grooves 23 (two for each in this embodiment) are provided at opposing positions. The upper end of the vent groove 23 is located at the upper end of the main body inner peripheral wall 12, and the lower end of the vent groove 23 is located at the base end of the main body inner peripheral wall 12. When the main body opening 17 is closed by the lid member 31, the vent groove 23 extends from the main body opening 17 to the bottom side of the main body storage portion 16 beyond the tip end surface of the protrusion 24. When the lid accommodating portion 36 of the lid member 31 is fitted into the cylindrical portion 14 , the vent groove 23 exhausts the compressed air in the main body accommodating portion 16 into the groove 18 .

[0031] A pair of protrusions 24 are provided on the inclined portion 22, further inward of the main body inner peripheral wall 12. The pair of protrusions 24 are provided on the upper side of a pair of longitudinal faces 15a that constitute the rectangular tubular portion 15. Each of the pair of protrusions 24 has a comb shape when viewed from a perspective facing the main body opening 17. Each protrusion 24 extends from the inclined portion 22 toward the main body opening 17 and includes a first break wall 24a and a second break wall 24b.

[0032] The first fracture wall 24a is an arc-shaped wall that stands inward of the main body inner peripheral wall 12 and spaced apart from the main body inner peripheral wall 12 in the inclined portion 22 that constitutes the second bottom. The second fracture wall 24b stands in the inclined portion 22 so as to extend linearly from the first fracture wall 24a toward the inside of the cylindrical portion 14. The tip surfaces of the first fracture wall 24a and the second fracture wall 24b extend in two mutually intersecting directions, and the plane including these two directions includes a plane parallel to the plane including the main body opening 17. In this embodiment, the tip surfaces are formed as a flush plane. That is, the tip surfaces of the first fracture wall 24a and the second fracture wall 24b are the same height.

[0033] The tip of the first breaking wall 24a and the tip of the second breaking wall 24b are lower in height than the tips of the main body inner peripheral wall 12 and the main body outer peripheral wall 13. In other words, the position of the tip surface of the protrusion 24 is closer to the main body opening 17 than the lower end of the vent groove 23. The cylindrical lid wall 33 that constitutes the lid accommodating section 36 of the lid member 31 is inserted between the main body inner peripheral wall 12 and the pair of protrusions 24. The tip surface of the protrusion 24 is the part that first comes into contact with the film 38 in the main body accommodating section 16 when the lid accommodating section 36 is fitted through the main body opening 17, and is the part that breaks the film 38.

[0034] Within the container body 11, the rectangular tubular portion 15 is located at the lowest position relative to the body opening 17. The rectangular tubular portion 15 is located below the cylindrical portion 14 and is a space continuous with the cylindrical portion 14. The bottom (first bottom) of the rectangular tubular portion 15 is also the bottom of the body storage portion 16. The bottom of the rectangular tubular portion 15 is located at the center between a pair of width faces 15b, and is configured with a curved surface that is continuous from the center of the bottom to the length faces 15a, with the deepest part being the center of the bottom extending parallel to the pair of length faces 15a. The rectangular tubular portion 15 stores the first agent 6a injected from the container 1 when the lid member 31 is in the state where the body opening 17 is opened. Furthermore, when the body opening 17 is closed by the lid member 31, the second agent 7 flowing down from the lid storage portion 36 of the lid member 31 is injected. That is, inside the rectangular tubular portion 15, a mixture 8 of the first agent 6a and the second agent 7 is stored.

[0035] The inclined portion 22 located between the cylindrical portion 14 and the rectangular cylindrical portion 15 forms the bottom (second bottom) of the cylindrical portion 14, and makes it easier for the second agent 7 to flow toward the rectangular cylindrical portion 15. The first agent 6a and the second agent 7 are mixed in the rectangular cylindrical portion 15. Furthermore, when the rectangular cylindrical portion 15 is attached to the attachment portion of the optical inspection device 4 in a state in which the first agent 6a or the mixed agent 8 is stored, measurement light is irradiated onto the width surface 15b that forms the rectangular cylindrical portion 15. The rectangular cylindrical portion 15 is positioned in the optical path of the measurement light in the attachment portion.

[0036] [Cover member] 5 and 6, the lid member 31 includes a lid plate 32, a lid cylindrical wall 33, and an insertion wall 34, and closes the main body opening 17. The lid member 31 is a molded product made of the same resin material as the container main body 11, glass, or the like.

[0037] The cover plate 32 is a circular plate whose outer diameter is slightly larger than that of the main body outer wall 13. The cover plate 32 has a pair of locking pieces 35 at opposing positions on its edge that are locked to the connecting pieces 19 of the container main body 11. The pair of locking pieces 35 have locking claws 35a at their tips that protrude outward. The pair of locking pieces 35 are inserted between the pair of connecting pieces 19 while bending slightly inward, and the locking claws 35a are locked to the connecting pieces 19 by elastically restoring.

[0038] The cylindrical lid wall 33 is a cylindrical wall that is fitted inside the main body inner circumferential wall 12 of the container main body 11. The inside of the cylindrical lid wall 33 forms a lid accommodating section 36. The lid accommodating section 36 is a bottomed recess with the lid plate 32 as its bottom, and accommodates the second agent 7. The height of the cylindrical lid wall 33 is set so that the cylindrical end of the cylindrical lid wall 33 is positioned slightly above the base end of the main body inner circumferential wall 12 when the lid member 31 closes the main body opening 17. In addition, the corner of the cylindrical end of the cylindrical lid wall 33 has recesses 33a in the circumferential direction. The highest tip surface between the recesses 33a becomes the fixing surface for the film 38. The cylindrical end of the cylindrical lid wall 33 forms an outlet 37 for the second agent 7.

[0039] A film 38 that closes the outlet 37 is disposed at the cylindrical end of the cylindrical lid wall 33. The film 38 is an aluminum seal or a resin seal. The film 38 has a circular shape sufficient to close the outlet 37. Burrs and the like may be formed on the outer edge of the film 38. When the cylindrical lid wall 33 is fitted inside the inner peripheral wall 12 of the main body, the burrs may become caught between the outer peripheral surface of the cylindrical lid wall 33 and the inner peripheral surface of the inner peripheral wall 12, hindering the fitting. The recess 33a provides a relief for the burrs during fitting. This allows the cylindrical lid wall 33 to be fitted inside the inner peripheral wall 12 even if there are burrs on the outer peripheral edge of the film 38.

[0040] The film 38 is fixed by heat welding, adhesive, etc. to the tip surface of the cylindrical end of the lid cylindrical wall 33, where the recess 33a is not formed. The film 38 is fixed with such strength that even if the film 38 is broken by the protrusion 24, the fixed portion of the film 38 will not be pulled by the protrusion 24 and will not peel off.

[0041] An insertion wall 34 is erected on the back surface of the cover plate 32, on the outer circumferential side of the cylindrical cover wall 33, at a distance from the cylindrical cover wall 33. The insertion wall 34 is an annular wall that is lower than the cylindrical cover wall 33. The insertion wall 34 is inserted into the groove 18. The tip of the insertion wall 34 is at a height that is slightly lower than the tip of the protrusion 24 when the cover member 31 closes the main body opening 17. The height of the insertion wall 34 is also set so that the tip does not come into contact with the bottom of the groove 18.

[0042] The base end of the insertion wall 34 is a thick portion 34a that is thicker than the tip end (see FIG. 7). That is, the outer diameter of the outer peripheral surface of the insertion wall 34 is shaped such that the thick portion 34a reduces the diameter from the base end to the tip end. This allows the insertion wall 34 to be press-fitted into the groove 18. The thicker the thick portion 34a at the base end of the insertion wall 34 is or the longer it extends toward the tip end, the more difficult it is for the cover member 31 to come off the main body opening 17.

[0043] A bottomed lid annular groove 39 is defined between the cylindrical lid wall 33 and the insertion wall 34. When the lid member 31 closes the main body opening 17, the main body inner circumferential wall 12 is inserted into the lid annular groove 39. The leading end of the main body inner circumferential wall 12 abuts against the bottom of the lid annular groove 39. In other words, the lid annular groove 39 prevents the lid member 31 from being pressed too hard against the container main body 11, resulting in damage and leakage of the first agent 6a, the second agent 7, the mixed agent 8, etc.

[0044] [Operation of the embodiment] As shown in Fig. 7, with the main body opening 17 of the container main body 11 open, the first agent 6a is poured from the container 1 into the container main body 11. When the first agent 6a is poured into the main body storage section 16, it flows down the inner surface of the inclined section 22 into the rectangular tubular section 15 and is stored there. At this time, the container main body 11 may be held by hand or poured on a desk. The container main body 11 can be placed stably on a desk because the support pieces 21 function as support legs.

[0045] In in vitro diagnosis, first, the container body 11, with the first agent 6a stored therein, is attached to the attachment portion of the optical inspection device 4. The rectangular tubular portion 15 side of the container body 11 is the insertion end into the attachment portion. When attaching the container body 11, the support piece 21 is engaged with the guide rail of the attachment portion and inserted. The positioning piece 21a is engaged with the recessed groove of the attachment portion, so that the container body 11 is positioned properly in the attachment portion and attached.

[0046] In the mounting section, the rectangular cylindrical portion 15 is placed in the optical path of the measurement light, and the measurement light is irradiated onto the width surface 15b of the rectangular cylindrical portion 15. The optical inspection device 4 thereby measures the blank value of the first agent 6a.

[0047] Thereafter, the container body 11 is removed from the attachment portion. Next, the lid member 31 is attached to the container body 11 so as to close the body opening 17. Specifically, the lid member 31 is pushed in, with the lid accommodating portion 36, which is closed by the film 38, facing the insertion side, so that the lid accommodating portion 36 fits into the cylindrical portion 14 formed inside the body inner peripheral wall 12. Then, the first breaking wall 24a and the second breaking wall 24b first come into contact with the film 38, causing the film 38 to break. Because the tip surfaces of the first breaking wall 24a and the second breaking wall 24b extend in two directions that intersect with each other, a wide area of the film 38 is broken at one time.

[0048] Furthermore, because the first breaking wall 24a has a shape that follows the inner circumferential surface of the cylindrical lid wall 33 that constitutes the lid accommodating portion 36, the portion of the film 38 that breaks at one time can be spread along the inner circumferential surface of the lid accommodating portion 36. Furthermore, because the second breaking wall 24b extends from the first breaking wall 24a toward the inside of the cylindrical portion 14, the portion of the film 38 that breaks at one time can be spread from the inner circumferential surface of the lid accommodating portion 36 toward the inside of the lid accommodating portion 36.

[0049] As shown in FIG. 8 , the lid member 31 is fitted until the tip of the main body inner peripheral wall 12 abuts against the bottom of the lid annular groove 39. The cylindrical lid wall 33 is press-fitted against the inside of the main body inner peripheral wall 12. Therefore, the internal pressure of the main body accommodating portion 16 increases as the cylindrical lid wall 33 is inserted. The vent groove 23 of the main body inner peripheral wall 12 releases the internal air of the main body accommodating portion 16 to the outside as the lid accommodating portion 36 is fitted into the cylindrical portion 14 while being pressed against the inside of the cylindrical portion 14. This allows the lid accommodating portion 36 to be fitted smoothly into the cylindrical portion 14. Furthermore, the increase in pressure in the main body accommodating portion 16 due to the fitting of the lid accommodating portion 36 into the cylindrical portion 14 is prevented. This prevents the first agent 6a, the second agent 7, the mixed agent 8, and other components from flowing out of the lid accommodating portion 36. At this time, even if the first agent 6a, the second agent 7, the mixed agent 8, etc. leak out together with the internal air of the main body storage portion 16, the leaked agents will collect in the groove 18.

[0050] The locking piece 35 of the lid member 31 is locked to the connecting piece 19 of the container body 11. This locks the state in which the lid member 31 closes the body opening 17. The second agent 7 flowing out from the film 38 broken by the tip surface of the protrusion 24 can be guided by the first breaking wall 24a and the second breaking wall 24b toward the inside of the cylindrical portion 14 and further toward the rectangular tubular portion 15. This makes it easier to store the mixed agent 8 in the rectangular tubular portion 15 used for optical inspection.

[0051] Thus, once the attachment of the lid member 31 to the container body 11 is completed, the mixing container 3 is again attached to the attachment portion of the optical inspection device 4. Then, in the attachment portion, the rectangular tubular portion 15 is placed in the optical path of the measurement light, and the measurement light is irradiated onto the width surface 15b of the rectangular tubular portion 15. This allows the optical inspection device 4 to measure the characteristic values of the admixture.

[0052] [Effects of the embodiment] The mixing vessel 3 as described above can provide the following effects. (1) The tip surfaces of the protruding pieces 24, which extend in two intersecting directions, break through the film 38. This makes it easier for the area of the film 38 that breaks at once to expand when the lid housing portion 36 is fitted. This improves mixability.

[0053] (2) In the protrusion 24, the tip surface having a comb shape has a surface portion extending in one direction and another surface portion extending in a different direction from the surface portion, so that the portion of the film 38 that is broken at one time can be expanded.

[0054] Furthermore, since the protruding piece 24 has a comb shape and is not a cylindrical cutting blade like a puncher, a part of the film 38 remains fixed to the lid cylinder wall 33. This prevents the film 38 from falling into the mixture 8 in the rectangular cylinder portion 15 and interfering with the measurement.

[0055] (3) In the protrusion 24, the first breaking wall 24a has a shape that follows the inner circumferential surface of the cylindrical lid wall 33 that constitutes the lid accommodating portion 36, so the portion of the film 38 that breaks at one time can be spread along the inner circumferential surface of the cylindrical lid wall 33. The second breaking wall 24b extends from the first breaking wall 24a toward the inside of the cylindrical lid wall 33, so the portion of the film 38 that breaks at one time can be spread from the inner circumferential surface of the cylindrical lid wall 33 toward the inside of the cylindrical lid wall 33. Furthermore, the second agent 7 that flows out from the film 38 that has been broken by the tip surface of the protrusion 24 can be guided by the protrusion 24 toward the inside of the cylindrical portion 14 and further toward the rectangular cylindrical portion 15. This also makes it easier to accommodate the mixed agent 8 in the rectangular cylindrical portion 15 used for optical inspection.

[0056] (4) The second bottom of the cylindrical portion 14, which is the inner surface of the inclined portion 22, is inclined downward toward the opening of the rectangular tubular portion 15. Therefore, the second agent 7 that flows out from the lid housing portion 36 along the protruding piece 24 can be efficiently guided to the rectangular tubular portion 15.

[0057] (5) The vent groove 23 releases the air inside the main body accommodating portion 16 to the outside when the lid accommodating portion 36 is fitted while being pressed against the inside of the main body inner peripheral wall 12. This allows the lid accommodating portion 36 to be fitted smoothly inside the main body inner peripheral wall 12. Furthermore, the main body accommodating portion 16 is prevented from becoming highly pressurized when the lid accommodating portion 36 is fitted inside the main body inner peripheral wall 12. This prevents the second agent 7 from becoming difficult to flow out of the lid accommodating portion 36.

[0058] (6) The vent groove 23 allows the internal air to escape to the outside even after the tip surface of the protrusion 24 breaks the film 38. This prevents the internal pressure of the main body accommodating portion 16 from increasing even if the lid accommodating portion 36 is further fitted after the film 38 breaks. Furthermore, even if the second agent 7 tends to remain inside the lid accommodating portion 36 due to the action of the surface tension of the second agent 7, the second agent 7 can easily flow out into the main body accommodating portion 16.

[0059] (7) When the lid housing portion 36 is fitted into the main body inner peripheral wall 12, the air inside the main body inner peripheral wall 12 flows through the vent groove 23 into the annular groove 18 between the main body inner peripheral wall 12 and the main body outer peripheral wall 13. At this time, even if the first agent 6a or the second agent 7 leaks out along with the air inside the main body housing portion 16, the leaked medicine and the like accumulate in the groove 18. This allows the air inside the main body housing portion 16 to escape, suppressing an increase in the internal pressure in the main body housing portion 16, while also suppressing leakage of medicine and the like from the main body housing portion 16.

[0060] The mixing vessel 3 can also be modified as follows. The vent groove 23 may be provided on the outer peripheral surface of the cylindrical lid wall 33 that constitutes the lid accommodating portion 36. The vent groove 23 may be provided on both the inner peripheral surface of the inner peripheral wall 12 of the main body and the outer peripheral surface of the cylindrical lid wall 33, or on either one of them.

[0061] The groove 18 does not have to be a continuous annular groove between the main body inner peripheral wall 12 and the main body outer peripheral wall 13. For example, the groove 18 may be configured as a plurality of concentric arc grooves provided intermittently in the circumferential direction. In this case, it is sufficient that the groove 18 is provided at least at a position corresponding to the upper end of the vent groove 23.

[0062] The outer circumferential wall 13 and the groove 18 may be omitted from the upper portion of the container body 11. In this case, the internal air and the like will be discharged to the outside through the vent groove 23. When the height of the protrusion 24 is low, the lower end of the vent groove 23 may be located above the tip end surface of the protrusion 24 .

[0063] The vent groove 23 may be omitted. In this case, a through hole serving as a vent hole in place of the vent groove 23 may be provided in the cover plate 32 in the inner region of the cylindrical cover wall 33 and / or in the bottom portion of the annular cover groove 39.

[0064] The inclined portion 22 may be omitted from the container body 11. In this case, the container body 11 has a cylindrical shape. The upper part of the container body 11 may be formed only by the inner peripheral wall 12 of the container body 11, instead of a double-wall structure.

[0065] In the protruding piece 24, two or one second breaking walls 24b may extend from the first breaking wall 24a in a direction different from that of the first breaking wall 24a. Also, four or more second breaking walls 24b may extend from the first breaking wall 24a in a direction different from that of the first breaking wall 24a.

[0066] The first breaking wall 24a does not have to have an arc shape that follows the main body inner peripheral wall 12 or the cover cylindrical wall 33. For example, the first breaking wall 24a may have a straight or wavy shape. The second breaking wall 24b may have an arc shape or a wavy shape instead of a straight shape.

[0067] The protruding piece 24 does not have to be a plate of constant thickness from the base end to the tip. For example, the protruding piece 24 may be thicker at the base end than at the tip, or may be thicker at the tip than at the base end, as long as the tip surface is flush.

[0068] The tip surface of the protrusion 24 extends in two mutually intersecting directions, and as long as the plane including these two directions includes a plane parallel to the plane including the main body opening 17, a protrusion or a recess may be provided on a part of the tip surface.

[0069] In FIG. 1, instead of using a container 1, the first agent 6 may be stored in the container body 11 by blocking the body opening 17 with a film, and when in use, the film may be peeled off and a specimen or the like may be added to the container body 11.

[0070] The first agent 6 and the second agent 7 may be liquid, or may be semi-fluid such as powder, gel, or granules. [Explanation of symbols]
