In addition, in FIG. 5A and FIG. 5B, illustration of the additive M2 is abbreviate | omitted for convenience of explanation.

  The mixing container set 12 according to the present embodiment is an oral nutritional agent (mixture M3) in which the taste, viscosity, components, and the like are changed by mixing and stirring the additive M2 in the solvent M1 in the container 14 before eating and drinking. ). However, the mixing container set 12 is not limited to the one for obtaining an oral nutrient. That is, the mixing container set 12 may be for obtaining a drug (mixture M3) to be administered to a living body, for example, by mixing the additive M2 with the solvent M1 before use.

  As shown in FIG. 1, the mixing container set 12 includes a container 14 that stores the solvent M1 and an additive container 10 that stores the additive M2. The container 14 is configured as a pouch container, and includes a flexible container body 16, a mouth portion 18 provided in the container body 16, and a cap 20 that is detachable from the mouth portion 18.

  The container body 16 is a bag configured in a bag shape by stacking flexible film materials made of soft resin such as polyvinyl chloride and polyolefin, or aluminum, and fusing or adhering at the peripheral seal portion. is there. The container body 16 is preferably configured to be transparent. In this case, when the additive M2 is mixed with the solvent M1 in the container body 16, the mixing condition (dissolving condition) of these substances can be easily visually recognized from the outside.

  As shown in FIG. 1, FIG. 4A, FIG. 4B, FIG. 7 and FIG. 8, the mouth portion 18 is integrally formed of a hard resin, and is fused or bonded to the container body 16 and is solvent M1. The inner hole 18a through which the additive M2 or the mixture M3 (solvent M1, etc.) flows is provided. A first connection screw portion 26 into which a screw portion (not shown) of the cap is screwed is formed on the outer peripheral surface of the mouth portion 18. A first connection taper surface 28 is formed on the distal end side of the inner peripheral surface of the mouth portion 18 and is inclined outward in the radial direction of the mouth portion 18 toward the distal end.

  As shown in FIGS. 2 and 3, the additive storage device 10 includes a connection portion 30 that can be attached to and detached from the mouth portion 18, a storage portion 32 in which a storage chamber 34 in which the additive M <b> 2 is stored, and a storage chamber. 34 is provided with a sealing film 36 for sealing the additive M2.

  The connection portion 30 is integrally formed of a hard resin, and includes a cylindrical outer cylinder portion 38, an annular portion 40 provided on the inner peripheral surface of the outer cylinder portion 38, and an inner end of the annular portion 40. A cylindrical inner cylinder portion 42 extending from one end to the one end side of the outer cylinder portion 38, and a first cylinder extending from the outer end portion of the annular portion 40 in a direction opposite to the extending direction of the annular portion 40. Part 44.

  A second connection screw portion 48 that is screwed into the first connection screw portion 26 is formed on the inner peripheral surface of the outer cylinder portion 38. In the present embodiment, the inner cylinder portion 42 is fitted into the inner hole 18a of the mouth portion 18 in a state where the first connection screw portion 26 and the second connection screw portion 48 are screwed together (see FIG. 4A and the like). At this time, the inner hole 42a of the inner cylinder portion 42 communicates with the inside of the container body 16 via the inner hole 18a of the mouth portion 18 (see FIG. 7).

  A first anti-slip portion 50 that functions as an anti-slip of the user's fingers is formed on the outer peripheral surface of the outer cylinder portion 38. In the present embodiment, the first anti-slip part 50 is configured by providing a plurality of convex parts extending over substantially the entire length of the outer cylinder part 38 at a predetermined interval around the entire circumference of the outer cylinder part 38. Has been. Such a first anti-slip portion 50 can be formed by knurling, for example. The size and shape of the first anti-slip portion 50 can be arbitrarily set, and may be configured by forming a recess on the outer peripheral surface of the outer cylinder portion 38.

  On one surface of the annular portion 40 (the surface facing the mouth portion 18), the solvent M1 or the like leaks from between the container 14 and the connection portion 30 by coming into liquid-tight contact with the tip surface of the mouth portion 18. An annular first seal protrusion 52 is formed to prevent this. The size and shape of the first seal protrusion 52 can be arbitrarily set. On the other surface of the annular portion 40 (the surface facing the inner hole of the first cylindrical portion 44), an inclined surface 54 that is inclined toward the inner cylinder portion 42 toward the radially inner side is formed.

  The inner cylinder part 42 is provided coaxially with the outer cylinder part 38 and is shorter than the outer cylinder part 38. A second connection taper surface 56 is formed on the outer peripheral surface of the inner cylinder portion 42 and is inclined inward in the radial direction of the inner cylinder portion 42 toward the tip. The second connection tapered surface 56 extends to the tip of the inner cylinder portion 42.

  As can be seen from FIG. 7, the inclination angle of the second connection taper surface 56 with respect to the axis of the inner cylinder portion 42 is set to be the same as the inclination angle of the first connection taper surface 28 with respect to the axis of the mouth portion 18. Therefore, the second connection taper surface 56 comes into liquid-tight contact with the first connection taper surface 28 in a state where the second connection screw portion 48 is fastened to the first connection screw portion 26. Thereby, it can suppress further that the solvent M1 etc. leak from between the opening | mouth part 18 and the connection part 30. FIG.

  As shown in FIGS. 2 and 3, the proximal end portion of the first cylindrical portion 44 is connected to the other end portion of the inner peripheral surface of the outer cylindrical portion 38. A first tapered surface 58 is formed on the inner peripheral surface of the first cylindrical portion 44 and is inclined radially outward toward the tip. A first screw portion 60 is formed on the outer peripheral surface of the first cylindrical portion 44.

  The housing portion 32 is integrally formed of a hard resin, and has a cylindrical peripheral wall portion 62, a closing portion 64 that closes an opening on one side of the peripheral wall portion 62, and a closing portion so as to be positioned in the peripheral wall portion 62. And a second cylindrical portion 66 extending from 64.

  The peripheral wall portion 62 and the second cylindrical portion 66 are provided coaxially with each other. On the inner peripheral surface of the peripheral wall portion 62, a second screw portion 68 that is screwed into the first screw portion 60 of the connection portion 30 is formed. The second cylindrical portion 66 is fitted into the inner hole 44a of the first cylindrical portion 44 in a state where the first screw portion 60 and the second screw portion 68 are screwed together (see FIG. 4A and the like).

  In the present embodiment, the force (tightening torque of the first screw portion 60 and the second screw portion 68) required to rotate the housing portion 32 with respect to the connection portion 30 causes the connection portion 30 to move with respect to the mouth portion 18. It is set so as to be larger than the force necessary for rotation (tightening torque of the first connection screw portion 26 and the second connection screw portion 48). Thereby, for example, even when the connection portion 30 is connected to the mouth portion 18 while the user grips the accommodating portion 32, the second connection screw portion 48 is tightened with respect to the first connection screw portion 26. The second screw portion 68 will be tightened with respect to the first screw portion 60 later.

  A second anti-slip portion 70 that functions as an anti-slip of the user's fingers is formed on the outer peripheral surface of the peripheral wall portion 62. In the present embodiment, the second anti-slip portion 70 is configured by providing a plurality of convex portions extending over substantially the entire length of the peripheral wall portion 62 at a predetermined interval around the entire periphery of the peripheral wall portion 62. Yes. Such a second anti-slip portion 70 can be formed, for example, by knurling. In addition, the magnitude | size and shape of the 2nd anti-slip | skid part 70 can be set arbitrarily, and you may comprise by forming a recessed part in the outer peripheral surface of the surrounding wall part 62. FIG.

  On one surface of the closing part 64, an annular second for preventing the solvent M <b> 1 and the like from leaking from between the connecting part 30 and the accommodating part 32 by contacting the tip surface of the first cylindrical part 44. A seal protrusion 72 is formed. The size and shape of the second seal protrusion 72 can be arbitrarily set.

  As can be seen from FIGS. 7 and 8, a second tapered surface 74 that is inclined radially inward toward the tip is formed on the outer peripheral surface of the second cylindrical portion 66. The inclination angle of the second tapered surface 74 with respect to the axis of the second cylindrical portion 66 is set to be the same as the inclination angle of the first tapered surface 58 with respect to the axis of the first cylindrical portion 44. Therefore, the second taper surface 74 comes into liquid-tight contact with the first taper surface 58 in a state where the second screw portion 68 is fastened to the first screw portion 60. Thereby, it can suppress further that the solvent M1 etc. leak from between the connection part 30 and the accommodating part 32. FIG.

  As shown in FIG. 3, the inner hole of the second cylindrical portion 66 functions as a storage chamber 34 that stores the additive M2. As the additive M2, for example, powders, tablets, granules, liquids and the like can be used. In general, powders are easier to mix (dissolve) in the solvent M1 more uniformly than tablets and granules, and have a longer storage period than liquids. Therefore, it is preferable to use a powder agent as the additive M2.

  The additive M2 can contain flavors (fragrances), gelling agents, nutrients and the like. Examples of nutrients include branched-chain amino acids (BCAA).

  A sealing film 36 for sealing the additive M2 in the accommodation chamber 34 is bonded to the distal end surface of the second cylindrical portion 66 (the end surface opposite to the closing portion 64). As the sealing film 36, an aluminum film can be suitably used, but a resin film or the like may be used. The edge portion of the sealing film 36 is bonded to the distal end surface of the second cylindrical portion 66.

  An annular recess 76 is formed on the outer peripheral surface of the distal end portion of the second cylindrical portion 66. The annular recess 76 is a clearance space (clearance) of the punch blade when the sealing film 36 is affixed at the time of manufacture and the excess portion is punch-cut. Thereby, the sealing film 36 can be efficiently formed along the outer shape of the tip portion of the second cylindrical portion 66. That is, since the sealing film 36 is prevented from protruding outside the second cylindrical portion 66, it is possible to prevent the sealing film 36 from being sandwiched between the first cylindrical portion 44 and the second cylindrical portion 66. it can.

  In the additive container 10 configured as described above, an opening projection 78 for opening the sealing film 36 from the outside of the storage chamber 34 is provided in the connection portion 30. Specifically, the opening projection 78 extends from the other end surface of the inner cylinder portion 42 toward the opening portion side in which the second cylindrical portion 66 of the first cylindrical portion 44 is inserted along the axial direction of the first cylindrical portion 44. Protruding.

  That is, the unsealing projection 78 accommodates the sealing film 36 from the outside of the accommodation chamber 34 by fastening the first screw portion 60 and the second screw portion 68 to each other (rotating the accommodation portion 32 with respect to the connection portion 30). It enters the storage chamber 34 while breaking along the rotation direction of the portion 32 (see FIGS. 4B to 5B and FIG. 7). Further, the unsealing projection 78 is provided so as to contact the vicinity of the inner peripheral surface of the second cylindrical portion 66 of the sealing film 36 (see FIG. 5A). Thereby, the sealing film 36 can be opened relatively large along the inner peripheral surface of the second cylindrical portion 66.

  The opening projection 78 extends by a predetermined angle in the circumferential direction of the inner cylinder portion 42 so as not to tear the sealing film 36 within a range of 360 ° (the sealing film 36 is not separated from the second cylindrical portion 66). doing. The predetermined angle is set to 30 ° to 90 °, preferably 45 ° to 75 °, and more preferably 60 °.

  When the predetermined angle is smaller than 30 °, the amount of rotation of the housing portion 32 required for opening the sealing film 36 with respect to the connection portion 30 is relatively large (of the first screw portion 60 and the second screw portion 68). Therefore, the additive container 10 tends to be large. On the other hand, if the predetermined angle is larger than 90 °, the sealing film 36 may be broken within a range of 360 °. If the said predetermined angle is 60 degrees, it can suppress reliably that the sealing film 36 is torn in the range of 360 degrees, and can achieve compactization of the additive accommodation tool 10 suitably.

  When the opening projection 78 is provided, when the first screw portion 60 and the second screw portion 68 reach the maximum tightening position, the sealing film 36 is moved in the rotation direction of the housing portion 32 by the opening projection 78. It is formed so as to be broken by a predetermined angle θ (for example, 300 °) less than 360 ° (see FIG. 5B). Thereby, it can further suppress that the sealing film 36 is cut | disconnected from the accommodating part 32 by the protrusion 78 for opening.

  The predetermined angle θ is preferably 180 ° or more, and more preferably 300 °. Thereby, the weight of the additive M2 makes it easy to turn over the separated portion of the sealing film 36 and makes it difficult to completely separate the portion.

  The inner surface of the opening projection 78 that faces the radially inner side of the first cylindrical portion 44 is inclined radially outward toward the tip. In other words, the unsealing projection 78 is gradually formed thinner toward the tip side. Thereby, the front-end | tip part of the processus | protrusion 78 for opening can be penetrated with respect to the sealing film 36 easily.

  As shown in FIGS. 2 and 5A to 6B, the additive container 10 includes a tightening direction (R1 direction) of the first screw portion 60 and the second screw portion 68 in a state where the sealing film 36 is opened. A rotation restricting portion 80 for restricting the rotation of the accommodating portion 32 relative to the connecting portion 30 in the opposite direction (R2 direction) is provided. The rotation restricting portion 80 includes a pair of first convex portions 82 provided on the other end surface of the outer cylindrical portion 38 of the connecting portion 30 at a position whose phase is shifted by 180 ° in the circumferential direction, and one of the peripheral wall portions 62 of the accommodating portion 32. It has a pair of 2nd convex part 84 provided in the position which the phase shifted 180 degrees in the circumferential direction at the end surface.

  As shown in FIG. 6A and FIG. 6B, each first convex portion 82 includes a first surface 82a extending obliquely from the other end surface of the outer tube portion 38 toward the peripheral wall portion 62 toward the R1 direction, and a first surface. A second surface 82b extending obliquely from the tip of 82a to the other end surface of the outer cylinder portion 38 in the R2 direction.

  Each of the second convex portions 84 includes a third surface 84a extending obliquely from the one end surface of the peripheral wall portion 62 toward the outer tube portion 38 toward the R2 direction, and an axis of the peripheral wall portion 62 from the tip of the third surface 84a. And a fourth surface 84 b extending to one end surface of the peripheral wall portion 62.

  The first convex portion 82 and the second convex portion 84 are formed so that the first surface 82a and the third surface 84a come into contact with each other when the accommodating portion 32 is rotated in the R1 direction with respect to the connecting portion 30. The portion 84 is formed so as to be able to get over the first convex portion 82. In addition, the first convex portion 82 and the second convex portion 84 have the fourth surface 84b and the second convex portion 84 when the accommodating portion 32 is rotated in the R2 direction with respect to the connecting portion 30 with the sealing film 36 opened. The second protrusions 84 are formed so that they cannot get over the first protrusions 82 by contacting the two surfaces 82b with each other.

  The mixing container set 12 including the additive container 10 according to the present embodiment is basically configured as described above. Next, a method of using the mixing container set 12 will be described. In the initial state, the container body 16 is sealed with the cap 20, and the first screw portion 60 and the second screw portion 68 are screwed together with the sealing film 36 not opened. To do.

  As shown in FIG. 1, first, the user removes the cap 20 from the container body 16, and connects the connection portion 30 of the additive container 10 containing the desired additive M2 to the mouth portion 18 of the container body 16. To do. That is, in a state where the user holds the first anti-slip portion 50, the user causes the second connection screw portion 48 to be screwed to the first connection screw portion 26 to rotate the connection portion 30 with respect to the container body 16 in the R1 direction. . Thereby, the 2nd connection screw part 48 is fastened reliably and smoothly with respect to the 1st connection screw part 26 (refer FIG. 4A).

  In addition, the user may rotate the additive storage device 10 in the R1 direction with respect to the container body 16 while holding the second anti-slip portion 70. Even in this case, the force (rotation resistance) required to rotate the housing portion 32 relative to the connection portion 30 is the force (rotation resistance) required to rotate the connection portion 30 relative to the mouth portion 18. Therefore, it is possible to prevent the sealing film 36 from being opened before the first connection screw portion 26 and the second connection screw portion 48 are tightened together.

  As shown in FIG. 4A, when the second connection screw portion 48 is tightened against the first connection screw portion 26, the inner cylinder portion 42 of the connection portion 30 is fitted into the inner hole 18 a of the mouth portion 18. At this time, the second connection taper surface 56 and the first connection taper surface 28 are in liquid-tight contact with each other, and the first seal protrusion 52 is elastically deformed and in liquid-tight contact with the distal end surface of the mouth portion 18. Thereby, it is suppressed that the solvent M1 etc. in the container 14 leaks from between the opening part 18 and the connection part 30. FIG.

  Subsequently, the user rotates the housing portion 32 in the R1 direction with respect to the connection portion 30 while holding the second anti-slip portion 70. Then, the first screw portion 60 and the second screw portion 68 are tightened together, and the tip of the unsealing projection 78 comes into contact with the outer surface of the sealing film 36. Since the sealing film 36 is pressed toward the tip of the opening projection 78 while rotating in the R1 direction, the tip of the opening projection 78 is on the inner peripheral surface of the first cylindrical portion 44 of the sealing film 36. It penetrates the vicinity (see FIG. 4B and FIG. 5A).

  Next, when the accommodating portion 32 is further rotated in the R1 direction, the sealing film 36 rotates in the R1 direction while contacting the side surface in the R2 direction of the opening projection 78 and proceeds to the proximal end side of the opening projection 78. . In other words, the opening projection 78 advances into the storage chamber 34. Therefore, the breaking part 86 of the sealing film 36 spreads along the R1 direction while widening.

  At this time, as shown in FIG. 6A, the first surface 82a of the first convex portion 82 and the third surface 84a of the second convex portion 84 come into contact with each other, and the second convex portion 84 gets over the first convex portion 82. Therefore, the accommodating portion 32 can be rotated in the R1 direction with respect to the connecting portion 30.

  And when the accommodating part 32 is rotated to the maximum tightening position of the 1st screw part 60 and the 2nd screw part 68, the sealing film 36 is only predetermined angle (theta) (for example, 300 degrees) in the circumferential direction by the protrusion 78 for opening. It is torn and opened (see FIG. 5B). At this time, as shown in FIG. 7, the inside of the accommodation chamber 34 is a fracture portion 86 of the sealing film 36, a communication hole of the connection portion 30 (the inner hole 44 a of the first cylindrical portion 44 and the inner hole 42 a of the inner cylindrical portion 42. ) And the inside of the container main body 16 through the inner hole 18a of the mouth portion 18, the additive M2 in the storage chamber 34 is introduced into the container main body 16.

  In the present embodiment, the additive M2 is guided to the inner hole 42a of the inner cylinder portion 42 by the inclined surface 54, so that the additive M2 can be prevented from remaining in the connection portion 30. Furthermore, since the sealing film 36 remains without being broken by a predetermined angle (for example, 60 °) in the circumferential direction, a part of the sealing film 36 is cut off from the accommodating portion 32 and dropped into the container body 16. There is nothing to do (see FIG. 5B and FIG. 7).

  In the maximum tightening position of the first screw portion 60 and the second screw portion 68, the first taper surface 58 and the second taper surface 74 are in liquid-tight contact with each other and the second seal protrusion 72 is elastically deformed. The front end surface of the first cylindrical portion 44 is in liquid-tight contact. That is, leakage of the solvent M1 and the like in the container 14 from between the connection portion 30 and the storage portion 32 is suppressed.

  Furthermore, at this time, the second surface 82b of the first convex portion 82 and the fourth surface 84b of the second convex portion 84 are in contact with each other, and the second convex portion 84 cannot get over the first convex portion 82. (See FIG. 6B). That is, the housing part 32 cannot be rotated in the R2 direction with respect to the connection part 30. Therefore, it is possible to prevent the storage portion 32 from being removed from the connection portion 30 and the solvent M1 and the like from leaking through the connection portion 30.

  Thereafter, the user agitates the solvent M1 to which the additive M2 has been added by shaking the container body 16 with the additive storage device 10. Thereby, the mixed agent M3 is obtained. Even when the mixing agent M3 flows into the storage chamber 34 during stirring, the mixing agent M3 in the storage chamber 34 is guided into the container body 16 by the inclined surface 54, so that the connecting agent 30 is mixed with the mixing agent 30. It is suppressed that M3 remains.

  Subsequently, as shown in FIG. 8, the user removes the additive container 10 from the mouth portion 18, and eats and drinks the mixed agent M <b> 3 through the inner hole 18 a of the mouth portion 18.

  According to the present embodiment, the sealing film 36 can be broken along the R1 direction of the housing portion 32 by the opening projection 78, so that the additive container 10 can be made compact. In addition, since the opening projection 78 is formed in the connection portion 30 instead of in the storage chamber 34, the opening projection 78 can be brought into direct contact with the sealing film 36. Thereby, the sealing film 36 can be opened smoothly.

  According to this embodiment, the connection part 30 has the 1st cylindrical part 44 in which the 1st screw part 60 was formed, and the accommodating part 32 had the surrounding wall part 62 in which the 2nd screw part 68 was formed, and the surrounding wall. There are a closing portion 64 that closes one opening of the portion 62, and a second cylindrical portion 66 that extends from the closing portion 64 and can be fitted into the inner hole 44 a of the first cylindrical portion 44. Then, the accommodation chamber 34 formed in the second cylindrical portion 66 is sealed with a sealing film 36 adhered to the second cylindrical portion 66, and the sealing film 36 is placed in the inner hole 44 a of the first cylindrical portion 44. An unsealing projection 78 for unsealing is located. Thereby, the opening projection 78 can be brought into contact with the sealing film 36 from the outside of the storage chamber 34 with a simple configuration.

  Of course, the additive container according to the present invention and the mixing container set including the same can take various configurations without departing from the gist of the present invention.
