Description

  The present invention relates to a container configured to mix two materials that are manufactured and stocked separately from each other and mixed in use.

  Substances that are separated when manufactured and stocked and mixed for use are used in various fields. Patent Documents 1 and 2 describe containers used for this type of application. The container described in Patent Document 1 includes a lower container having an upper opening end closed with an aluminum foil, and an upper container having a lower opening end closed with an aluminum foil in the same manner. These open ends are configured to be screwed into and connected to both upper and lower sides of the cylindrical body. A ring-shaped protrusion that breaks through the aluminum foil of the lower container and the aluminum foil of the upper container is provided at a substantially central portion in the axial direction of the cylindrical body. Furthermore, between the lower container and the upper container, a stopper ring that is abutted against the shoulder of each container is sandwiched, and the stopper ring is vertically divided into two parts. The upper end portion of the stopper ring is connected to the cylindrical body by a breakable connecting band, and the lower end portion of the upper stopper ring is connected to the cylindrical body by a breakable connecting band.

  Therefore, in the container described in Patent Document 1, when the upper container is rotated with respect to the lower container, a force that causes at least one of the upper and lower containers to be screwed into the cylindrical body is generated by the action of the screw. As a result, one of the connecting bands is broken and the upper container or the lower container is screwed into the cylindrical body. As a result, the protrusion breaks through the aluminum foil, and finally both the upper and lower aluminum foils are ruptured so that the upper container and the lower container communicate with each other, and the liquids stored in the respective containers are mixed.

  Patent Document 2 describes a mixing container in which not only liquids but also liquids and powders can be mixed. The mixing container described in Patent Document 2 is a lower container whose upper end is similarly sealed by fitting and integrating a cylindrical holder with a lower container whose open end is sealed with an aluminum foil. Is fitted into the holder in a liquid-tight state from above. A ring-shaped safety pin that is partially cut open is fitted between the upper end of the holder and the shoulder of the upper container, so that the upper container cannot be pushed down when the safety pin is fitted. It has become. In addition, a blade having a vertex in both the vertical direction at the center is disposed between the upper end of the lower container inserted into the holder and the lower end of the upper container. It is hold | maintained between the lower container and the upper container by the several pin penetrated up and down.

  Therefore, in the mixing container described in Patent Document 2, it is possible to push down the upper container by pulling out the safety pin. When the upper container is pushed down in this state, the pin holding the blade is bent. The openings of both the upper and lower containers approach, and as a result, the blades pierce the upper and lower seals so that the upper and lower containers communicate with each other, and the liquid or powder contained in each container is mixed.

Japanese Utility Model Publication No. 3-22131 Japanese Utility Model Publication No. 57-43785

  The mixing container described in the cited document 1 is configured so as to hold the lower container and the upper container at a predetermined interval by a stopper ring provided with a connecting band that is easily broken at an intermediate portion. Since the band is configured to break easily, the upper container is inadvertently pushed down when assembling the container or transporting the container to a store, etc. There is a risk that the contents of each container may be mixed. Moreover, when opening, it is necessary to open the aluminum foil of a lower side container and an upper side container separately, and opening is difficult.

  On the other hand, in the mixing container described in Patent Document 2, since the cutter is a single piece, the blade protrudes up and down, and when assembling the container, the aluminum foil may be damaged. In addition, since a safety pin is provided, it is possible to prevent the two liquids from being inadvertently mixed, but when the two liquids are mixed and stirred, the upper container or the lower container moves in the axial direction. In addition, a shoulder part and a small diameter part for fitting the safety pin must be formed in the upper container, and the shape of the upper container is restricted. For example, when a vial containing a freeze-dried preparation is used as the upper container, its shape is suitable for the original function as a vial and is preferably suitable for freeze-drying treatment. A shape for a so-called lock function when used as a container must be added.

  This invention has been made against the background described above, and by simplifying the configuration and reducing the number of parts, it is easy to assemble, open easily, there is no risk of misopening, and when mixed and stirred An object of the present invention is to provide a two-substance mixing container in which two containers do not move in the axial direction.

  In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that two containers in which open ends sealed by a thin film material are arranged to face each other are connected by a sleeve and the open end sealed by the thin film material. An opening tool with a blade that pierces the thin film material is placed between them, the two containers are approached, the blade of the opening tool is pierced into each thin film material, and each container is opened. In the two-material mixing container configured to mix the contained substances, the sleeve is connected to the one container so as to be integrated, and the other container is moved back and forth in the axial direction to the sleeve. A rubber cap is press-fitted into the end of the other container that is inserted in a rotatable manner and protrudes from the sleeve of the other container, and the rubber cap is inserted into the other container. An outer lid that prevents the container from coming off is put on the rubber cap and is engaged with a flange formed on the other container, and further, a cylindrical skirt portion constituting the outer lid. The distal end portion is connected to the sleeve.

  According to a second aspect of the present invention, in the first aspect of the present invention, one of a locking concave portion that restricts relative movement of the outer lid with respect to the sleeve and a protrusion that engages with the locking concave portion is the outer lid. One of the sleeve and the other of the locking recess and the protrusion is formed on the other of the outer lid and the sleeve, and the protrusion extends in the axial direction of the sleeve and the sleeve. The two-substance mixing container is characterized in that a guide groove for continuously guiding in the rotation direction is formed in either the outer lid or the sleeve.

  Further, the invention of claim 3 is that in the invention of claim 1 or 2, the outer lid moves in a direction in which the other container approaches the one container by abutting the tip of the skirt portion. The two-material mixing container is characterized in that a stop ring for blocking is fitted on the outer peripheral side of the sleeve.

  According to the present invention, the other container is inserted into the sleeve connected so as to be integrated with one container so that the other container can move in the axial direction and the rotational direction, and protrudes from the sleeve of the other container. A rubber cap is press-fitted into the end, and an outer lid that prevents the rubber cap from being removed is put on the end of the other container. The outer lid is engaged with the other container so as not to be detached from the other container, and the skirt portion of the outer lid is connected to the sleeve. Therefore, the outer lid has both a function for preventing the rubber cap from coming off and a function for connecting the other container to the one container via the sleeve, and the number of parts is reduced accordingly. Therefore, the mixing container can be easily assembled, easily opened, and there is no risk of accidental opening. Further, since the other container does not need to have a special shape or part for constituting as a mixing container, the restriction on the shape of the other container can be reduced.

It is sectional drawing which shows an example of the mixing container which concerns on this invention. It is a partial side view which shows the shape of the groove | channel currently formed in the sleeve, and the recessed part for engagement. It is sectional drawing of the state which pushed the vial into the solution container side and stabbed the blade in the thin film material. It is sectional drawing which shows the other example of the mixing container which concerns on this invention.

  The present invention will be described based on specific examples. The mixing container according to the present invention is a container for mixing liquid and powder, or a container for mixing different types of liquids or powders. An example in which the prepared powder is mixed with a solution for dissolving the powder will be described. FIG. 1 is a cross-sectional view showing an example of this. The mixing container shown here is a freeze-dried product in which a vial 2 is connected as an upper container to a lower solution container 1 and accommodated in the vial 2. The preparation is mixed with the solution in the solution container 1. The solution container 1 includes a main body portion 3 and a mouth / neck portion 4 formed on the upper portion thereof for connection. The main body portion 3 is formed of a soft plastic and is configured to absorb changes in internal pressure by deformation. It has a cubic shape or a rectangular parallelepiped shape, and its four surfaces are somewhat depressed, and the four surfaces easily bulge outward to suppress an increase in internal pressure. The mouth-and-neck portion 4 is formed thick with the same material as the main body portion 3 so as to have a predetermined rigidity or strength, and a ridge portion 5 is formed on the outer peripheral surface thereof. A thin film material (for example, an aluminum sheet) 6 that can be easily broken and can ensure airtightness and liquid tightness is attached to the upper end portion (opening end portion) of the mouth and neck portion 4. It is sealed by. Further, an opening tool 7 is arranged on the upper surface side of the thin film material 6.

  The opening device 7 is provided with a plurality of (for example, four) blades 7b inside an annular frame 7a having the same contour as that of the upper end of the mouth / neck portion 4. These blades 7b are for piercing a thin film material such as an aluminum sheet to break the thin film material and moving in the plane direction of the thin film material to open the thin film material. It is provided in the radial direction between the frame 7a. The thickness of each blade 7b is thinner toward the upper side and thicker toward the outer peripheral side, and the height is lower at the center side (the connecting portion 7c side) and highest at the outer peripheral side, The most protruding part is pointed. And the upper edge (ridge line along a radial direction) 7d of each blade 7b is a cutting blade when piercing the thin film material. In addition, one side surface (one side surface in the circumferential direction of the annular frame 7a) of each blade 7b is perpendicular to the plane including the annular frame 7a. The other side surface forming the cutting blade 7d is inclined with respect to the plane including the annular frame 7a. Accordingly, an edge 7e where the inclined surface and the end face on the outer peripheral side of the blade 7b intersect is an inclined edge, and this edge 7e is a cutting blade for cutting the thin film material in the surface direction. In addition, the part between the some blades 7b is fan-shaped open, and the thin film material 6 which has sealed the said mouth-and-neck part 4 is exposed.

  On the other hand, the vial 2 is a container that has heat resistance and strength that can withstand vacuum freeze-drying treatment, and that can hold the powder obtained by vacuum freeze-drying treatment in an airtight state. 8 is formed in a cylindrical shape having a slightly smaller diameter than the above-mentioned mouth-and-neck portion 4, and a flange 9 extending to the outer peripheral side is formed at the upper end portion thereof. Further, a thin film material (for example, an aluminum sheet) 10 that can be easily broken and can ensure airtightness and liquid tightness is attached to the lower end portion of the main body portion 8, and is sealed by the thin film material 10. On the surface side of the thin film material 10, that is, on the lower end surface of the vial 2, the opening device 7 having the same configuration as the opening device 7 on the side of the dissolution liquid container 1 is provided with the blade 7b protruding downward. ing. Further, the opening device 7 is disposed such that the blade 7b on the side of the dissolution liquid container 1 and the blade 7b on the side of the vial 2 are in contact with each other, and the blade 7b on the side of the vial 2 is positioned downstream in the clockwise direction. Yes. The opening device 7 may be integrated with the thin film material 10 in advance, or may be attached to the surface of the thin film material 10, and further connected to the lower end of the main body portion 8 by an appropriate means. May be.

  A rubber cap 11 is press-fitted into the upper end opening of the main body portion 8. The rubber cap 11 includes a cylindrical portion 11a having an outer diameter equal to or larger than the inner diameter of the main body portion 8, and a flange portion 11b formed at the upper end of the cylindrical portion 11a. A cut 11c along the diameter direction is formed in a range from the lower end portion to the substantially central portion in the axial direction. This notch 11c is for communicating the inside and the outside of the main body portion 8 when the rubber cap 11 is press-fitted into the main body portion 8 to the half-plugged state.

  An outer lid 12 is attached to the upper side of the rubber cap 11. The outer lid 12 also serves to prevent the rubber cap 11 from coming off, and is formed of a thin plate made of aluminum or an alloy thereof. The outer lid 12 is placed on a rubber cap 11 that is completely plugged into the main body portion 8, and the outer peripheral portion is squeezed below the flange 9 in the main body portion 8 to sandwich the flange 9. And attached to the main body portion 8. Further, a cylindrical skirt portion 12b extending downward from the narrowed portion 12a sandwiching the flange 9 is provided, and a plurality of engaging projections 12c projecting inwardly on the inner surface of the lower end portion of the skirt portion 12b. Are formed at regular intervals in the circumferential direction. An opening 12d is formed at the center of the upper surface of the outer lid 12, and an injection needle (not shown) can be inserted into the rubber cap 11 from here.

  Next, the sleeve 13 that connects the solution container 1 and the vial 2 will be described. In the specific example shown in the figure, the sleeve 13 is configured to be integrated with the dissolution liquid container 1 which is a lower container. The inner diameter of the lower end portion of the sleeve 13 is formed in a cylindrical shape having an inner diameter substantially equal to the outer diameter of the protrusion 5 formed on the neck 4 of the dissolution liquid container 1 described above. An engaging protrusion 14 is formed on the inner surface of the protrusion to engage with the lower side of the protrusion 5. Further, an O-ring 15 that is engaged with the upper surface of the protrusion 5 in the drawing and is in close contact with the outer peripheral surface of the mouth-and-neck portion 4 in a liquid-tight state or an air-tight state is fitted to the inner peripheral surface of the sleeve 13. . The O-ring 15 is sandwiched between a stepped portion (shoulder portion) formed on the inner peripheral surface of the sleeve 13 and the upper surface of the protruding portion 5. And is closely fitted to the outer neck surface of the ridge 5 and attached to the solution container 1. In this state, the protrusion 5 and the O-ring 15 sandwich the protrusion 5 in the vertical direction, so that the sleeve 13 is integrated with the solution container 1 after all.

  A portion of the sleeve 13 extending upward from the dissolution liquid container 1 is formed in a cylindrical shape having an inner diameter equal to the outer diameter of the main body portion 8 of the vial 2 described above, and the main body portion 8 of the vial 2 is provided here. Has been inserted. The space between the inner peripheral surface of the sleeve 13 and the outer peripheral surface of the body portion 8 of the vial 2 is sealed in a liquid-tight state or an air-tight state by a seal ring 16 fitted in the inner peripheral surface of the sleeve 13. Yes. The upper end portion of the sleeve 13 has a smaller outer diameter than the portion below it, and that portion is a shoulder portion 17. A stop ring 18 is fitted over the shoulder 17. The stop ring 18 is a member having a substantially annular shape that has a slit in a part thereof and can be removed from the sleeve 13 by opening the slit portion, and its width (length in the axial direction) is a shoulder portion. It is about half the length from 17 to the upper end of the sleeve 13. The lower end of the skirt portion 12b of the outer lid 12 is in contact with the upper end portion of the stop ring 18. That is, the stop ring 18 keeps the positions of the outer lid 12 and the vial 2 so that the outer lid 12 and the vial 2 are not pushed down with respect to the sleeve 13 by contacting the lower end of the outer lid 12.

  The configuration for maintaining the state in which the lower end of the outer lid 12 is fitted to the sleeve 13 will be described. The inner surface of the lower end of the skirt portion 12b is disposed on the outer peripheral surface of the upper end of the sleeve 13 above the stop ring 18 described above. A guide groove and a locking recess are formed in which the engaging protrusions 12c formed on the locking member 12 are fitted. FIG. 2 is a partial side view showing an example, in which a spiral groove 19a is formed obliquely from the upper end of the sleeve 13, and a first locking recess 19b is formed at a slight interval on the tip side. . That is, by rotating the outer lid 12 with respect to the sleeve 13, the engaging projection 12c formed at the lower end of the skirt portion 12b moves in the spiral direction along the spiral groove 19a. Is screwed into the sleeve 13. Then, when the engaging protrusion 12c gets over the distal end portion of the spiral groove 19a and fits into the locking recess 19b, a resistance force acts on the relative movement of the outer lid 12 with respect to the sleeve 13, and thus the outer protrusion 12c. The state where the lid 12 is attached to the sleeve 13 is maintained.

  An opening groove 19c extending in the up and down direction (axial direction) and extending in the horizontal direction (circumferential direction) is formed below the first locking recess 19b, and the distal end side of the portion extending in the horizontal direction is formed. A second locking recess 19d is formed at a slight interval. Therefore, when the engaging projection 12c is fitted into the first locking recess 19b and the outer lid 12 attached to the sleeve 13 is pressed down strongly, the engaging projection 12c becomes the first locking recess 19b. And then enters the opening groove 19c. That is, the outer lid 12 and the vial 2 connected integrally therewith are pushed down with respect to the sleeve 13 and the solution container 1 and then can be rotated. Then, after rotating by a predetermined angle and then rotating strongly, the engaging protrusion 12c comes out of the opening groove 19c and fits into the second locking recess 19d, and the outer lid 12 and the vial 2 are in the so-called opening position. Maintained. The opening groove 19c and the second locking recess 19d are formed at a position where the engaging protrusion 12c is fitted when the stop ring 18 is removed and the outer lid 12 is lowered with respect to the sleeve 13. Yes.

  Next, the operation will be described. FIG. 1 shows a state in which a stop ring 18 is fitted, and a vial bottle in which a sleeve 13 is fitted to the mouth and neck portion 4 of the solution container 1 and a rubber cap 11 is fixed by an outer lid 12. 2 is inserted into the sleeve 13 from above. The lower end portion of the skirt portion 12 b in the outer lid 12 extends to the outer peripheral surface of the upper end portion of the sleeve 13, and the engaging projection portion 12 c formed at the lower end of the skirt portion 12 b is the spiral groove 19 a of the sleeve 13. The outer cover 12 is connected to the sleeve 13 by moving to the first locking recess 19b through the engagement and engaging with the first locking recess 19b. That is, the vial 2 fitted to the sleeve 13 is fixed by the outer lid 12 so as not to come out of the sleeve 13. Further, the lower end of the skirt portion 12b abuts against the stop ring 18, and therefore, the dissolving liquid container 1 receives a pressing force that is inadvertently applied to the vial 2 through the outer lid 12, the stop ring 18 and the sleeve 13, and the dissolving liquid. The container 1 and the vial 2 are prevented from approaching each other. Thus, the two-substance mixing container of the present invention is assembled without any risk of damaging the thin film materials 6 and 10 because the opening device 7 is disposed on the solution container 1 side and the vial container 2 side, respectively. Is possible. At this time, each blade 7b of the opening device 7 is assembled in contact with the blade 7b on the dissolution liquid container 1 side with the blade 7b on the vial 2 side positioned on the downstream side in the clockwise direction.

  When mixing the lysate contained in the lysate container 1 and the lyophilized preparation contained in the vial 2, first, the stop ring 18 is pulled out from the sleeve 13, and the outer lid 12 is lowered with respect to the sleeve 13. It is in a state that can be made to. Next, when a strong pressing force is applied to the outer lid 12, the engaging protrusion 12c formed on the inner surface of the lower end of the skirt portion 12b comes out of the first locking recess 19b and enters the aforementioned opening groove 19c. As a result, the outer lid 12 and the vial 2 integrated therewith can be easily pushed down and rotated. FIG. 3 shows a state in which the outer lid 12 and the vial 2 are pushed down, and the upper end portion of the dissolution liquid container 1 and the lower end portion of the vial bottle 2 come close to each other, so that the opening device 7 provided for each of them. The blade 7b is pierced into the opposing thin film materials 6 and 10, and the thin film materials 6 and 10 are cut.

  Since the blade 7b in each opening tool 7 is provided in the radial direction from the connecting portion 7c provided in the center, the thin film materials 6 and 10 are cut at portions corresponding to the connecting portion 7c. The portion that remains without being connected and that is opposed in the diametrical direction through the portion (or the substantially opposed portion) is maintained in a connected state. That is, incisions are made at a plurality of locations on the thin film materials 6 and 10, but the state in which tension is applied to the other portions is maintained, and the thin film materials 6 and 10 are in a tensioned state.

  When the outer lid 12 and the vial 2 are pushed down as described above and then rotated clockwise, the opening device 7 attached to the lower end of the vial 2 is rotated. The rotation direction is a direction in which the edge (cutting blade) 7e formed at the outer peripheral end of the blade 7b cuts the thin film material 6. When the vial 2 rotates as described above, the opening 7 on the side of the solution container 1 rotates in the direction opposite to the direction of rotation of the vial 2 relative to the vial 2, so that the side of the solution container 1 Then, the blade 7b of the opening tool 7 cuts through the thin film material 10 that seals the vial 2.

  Since the edges 7e formed at the outer peripheral ends of the blades 7b are cutting blades, the edges 7e cut the outer peripheral portions of the thin film materials 6 and 10 in an arc shape. Since each blade 7b has a plate shape arranged along the radial direction as described above, the portion cut in the arc shape by the edge 7e is pushed by the corresponding blade 7b and gradually accompanying with it. Rounded. That is, each thin film material 6, 10 is in a tensioned state, and is cut by the edge 7 e in that state, so that the cutting line has an arc shape designed for design, Further, the portion where the tension is not applied after being cut is supported by the portion where the tension is applied and the portion where the tension is not applied is pushed by the blade 7b. The part that is no longer applied is rounded to the expected shape. It should be noted that the portions where the tension is not applied after being cut are collected in a folded state without being rounded depending on the material of the thin film materials 6 and 10. In any case, the cut thin film materials 6 and 10 are collected into a specific shape. At this time, the blade 7b on the side of the vial 2 stops in contact with the blade 7b on the side of the solution container 1 located on the downstream side in the clockwise direction, and at the same time, the engaging protrusion 12c enters the second locking recess 19d, The outer lid 12 is fixed.

  Thus, when the solution container 1 and the vial bottle 2 are opened, the powder enclosed in the vial bottle 2 falls into the solution container 1 and dissolves in the solution. In that case, at the open ends of the solution container 1 and the vial 2, the blade 7 b and the connecting portion 7 c of the opening tool 7 or the uncut portions of the thin film materials 6 and 10 are left across. Since the shape is a shape specified by design and the shape of the cut portions of the thin film materials 6 and 10 is also specified as described above, the powder contained in the vial 2 Can be prevented or suppressed from entering and remaining undissolved. In particular, since the engaging protrusion 12c is engaged with the second locking recess 19d, the outer lid 12 moves even if the dissolution liquid container 1 and the vial 2 connected by the sleeve 13 are shaken strongly. Since the internal solution can be stirred without fear, it is possible to reliably avoid leaving undissolved powder and to prevent variations in the concentration of the content liquid.

  Also in the mixing container according to the present invention, since the solution container 1 and the vial 2 connected by the sleeve 13 are brought close to each other, the solution container 1 and the vial 2 are opened and connected. Then, the internal volume as a whole becomes smaller than the internal volume in the previous state. However, in the above configuration, since the main body portion 3 of the dissolution liquid container 1 has a soft structure that easily expands, an increase in internal pressure can be prevented or suppressed. Therefore, when the internal solution is taken out by piercing the rubber cap 11 with an injection needle, it is possible to prevent a situation in which the content liquid is ejected.

  As described above, in the mixing container according to the present invention, the outer lid 12 holding down the rubber cap 11 also serves as a member for connecting the vial 2 to the sleeve 13. Therefore, the member for fixing the rubber cap 11 is used. In addition, there is no need to provide a member for connecting the vial 2 to the sleeve 13. Therefore, the number of parts can be reduced, and the external shape of the vial 2 is not required to be a special shape for assembling as a mixing container, and its manufacture and handling are facilitated.

  In addition, this invention is not limited to the specific example mentioned above, Comprising: The outer cover 12 is good also as a product made from a synthetic resin not depending on a metal. An example thereof is shown in FIG. 4, and the outer lid 12 in the mixing container shown here is integrally formed of synthetic resin. More specifically, the outer lid 12 has a substantially bottomed cylindrical shape as a whole, and the opening 12c described above is formed in a portion corresponding to the bottom, that is, a portion that contacts the rubber cap 11 and presses the rubber cap 11. Is formed. Further, the cylindrical portion is the skirt portion 12b described above, and a protrusion 12e is formed on the inner surface of the skirt portion 12b so as to protrude inward instead of the above-described narrowing portion 12a. That is, by engaging the protrusion 12e with the lower side of the flange 9 of the vial 2 with the portion corresponding to the bottom portion in close contact with the upper surface of the rubber cap 11, the rubber cap 11 is attached to the vial 2. It is configured to be fixed. Further, an engaging protrusion 12c that engages with the guide groove of the sleeve 13 is formed on the inner surface of the lower end of the skirt portion 11b, and the engaging protrusion 12c fits into the first locking recess 19b in the guide groove. The lower end edge of the skirt portion 12 is configured to come into contact with the stop ring 18 in the recessed state.

  Therefore, even if the mixing container is configured as shown in FIG. 4, if the outer lid 12 is pushed down with the stop ring 18 removed, the vial 2 is pushed down to the solution container 1 side together with the outer lid 12. As a result, the blade 7b in each opening tool 7 pierces the thin film materials 10 and 6 in the vial 2 and the solution container 1 as shown in FIG. Then, by rotating the outer lid 12, the vial 2 integral with the outer lid 12 is rotated. As a result, the thin film materials 10 and 6 are cut and opened in an arc shape by the blade 7b. Thus, even when configured as shown in FIG. 4, the same operation and effect as when configured as shown in FIG. 1 can be obtained.

  In each of the above-described specific examples, a guide groove or a locking recess for moving and rotating the outer lid 12 in the axial direction with respect to the sleeve 13 is formed in the sleeve 13, and an engaging protrusion that engages with the guide groove. Although the portion 12c is formed on the outer lid 12, in the present invention, on the contrary, the guide groove or the skirt portion of the locking concave outer lid may be formed, and the engaging projection may be formed on the sleeve. .
