Description

  The present invention relates to a mixing container capable of mixing a first agent and a second agent separately accommodated during use.

  In containers that contain various beverages, etc., in addition to cleaning and disinfecting liquids, the first agent and the second agent can be separately contained in one container, and these can be mixed at the time of use. Container is used. As such a mixing container, for example, Patent Document 1 discloses that a second agent is accommodated between a base body having a housing space for storing a first agent, a base attached to the mouth of the main body portion, and the base. And a cap that is screwed to the base. When the cap is tightened, the partition held by the base is released, the second agent falls into the accommodation space, and the first agent and the second agent mix together. A mixing vessel is shown. According to such a mixing container, since the operation | work which throws in a 2nd agent in the container which accommodated the 1st agent can be skipped, there exists an advantage that it is convenient.

JP 2010-52786 A

  Although the conventional mixing container has such advantages, it has a problem that it is difficult to immediately determine from the outside of the container that the second agent has been added to the first agent. For example, in the mixing container disclosed in Patent Document 1, when the cap is tightened to add the second agent, the cap approaches the base. For this reason, although it can be known that the second agent has been added to the first agent by confirming the position of the cap, it is difficult to determine the difference in the position of the cap at first glance.

  An object of the present invention is to solve such problems, and to provide a mixing container that can immediately determine that the second agent has been added to the first agent even from outside the container. Objective.

The present invention, a container body having a storage space for storing the first agent,
A base having a top wall covering the mouth of the container body, and a base provided with a blade part standing upward and a communication port leading to the accommodation space on the top wall;
A filling body having a wall portion having a covered cylinder shape, and a seal portion that closes the bottom opening of the wall portion and accommodates the second agent between the wall portion;
A cap that is mounted so as to be vertically movable with respect to the base while supporting the filler in a state where the seal portion is positioned above the blade portion and the communication port by a connecting piece connected to the filler;
An identification body located above the filling body and held by the cap, and a mixing container comprising:
The identification body moves the cap downward, the blade portion breaks the seal portion, and when the second agent is introduced into the accommodation space through the communication port, the wall portion pushes against the top wall. In this case, it is a mixing container that drops from the cap as the filler moves upward with respect to the cap.

  It is preferable that the identification body is held on the cap by a claw portion hooked on a locking portion provided on the cap.

  The cap has an annular wall that surrounds the side wall of the identification body. When the identification body is held by the cap, the identification body bends toward the side wall by the annular wall, and when the cap is dropped from the cap. It is preferable to have an elastic piece that recovers in a direction away from the side wall.

  It is preferable that the identification body is held by the cap by being connected to the cap via a weakened portion.

  Preferably, a virgin ring is provided between the base and the cap to prevent the cap from moving downward relative to the base.

  In the mixing container of the present invention, by moving the cap downward toward the base, the base blade part breaks the seal part of the filling body containing the second agent, and thereby the container main body containing the first agent The second agent is introduced into the storage space. Further, at this time, the wall portion of the filling body presses against the top wall of the base and moves upward with respect to the cap, so that the identification body positioned above the filling body and held by the cap falls off from the cap. That is, since it can be immediately determined whether or not the identifier remains in the cap, it is possible to easily determine whether or not the second agent has been introduced.

  By the way, when holding the identification body in the cap, in order to prevent the identification body from dropping before the seal part of the filling body is broken, it is compared with the resistance force when breaking the seal part. It is assumed that the holding power of the identification body held by the cap is set high. Here, in the case where the identification body is provided with a claw portion that is hooked on the locking portion provided on the cap, the identification body can be held on the cap with a somewhat strong holding force, so that the seal portion is not broken. Therefore, it is possible to effectively prevent a problem that the identification body falls off.

  In addition, the cap is provided with an annular wall surrounding the side wall of the identification body, and when the identification body is held by the cap, it bends toward the side wall by the annular wall, while when it is detached from the cap, it moves away from the side wall. In the case where an elastic piece to be restored is provided, even if the discriminating identification body is to be attached to the cap, the elastic piece can obstruct the attachment to the cap. As a result, the discriminating body does not remain in the cap even though the second agent has been introduced, so that it is always possible to correctly determine whether or not the second agent has been introduced.

  Further, by connecting the identification body to the cap via the weakening portion, it is possible to prevent reattachment of the identification body that has fallen.

  If a virgin ring that prevents the cap from moving downward relative to the base is provided between the base and the cap, the cap will not be moved inadvertently, preventing unintentional injection of the second agent. can do.

  The filling body 4 includes a wall portion 4a having a covered cylinder shape, and a filling space S2 for accommodating the second agent is formed inside the wall portion 4a. The wall portion 4a of the present embodiment has a cylindrical portion having a cylindrical shape and an upper portion having a disk shape corresponding thereto, but is not limited to this shape. The shape portion may be a polygonal cylindrical shape, and the upper portion may be a polygonal plate shape corresponding to this. Further, a seal portion 4b formed of a thin sheet is fixed to the bottom opening of the wall portion 4a to close the filling space S2.

  The cap 5 includes a cylindrical inner peripheral wall 5a located on the radially inner side of the cylindrical wall 3e. On the radially inner side of the inner peripheral wall 5a, a thin connecting piece 5b that is integrally connected to the wall portion 4a is provided. Further, a flange portion 5c extending outward in the radial direction is provided at the upper end portion of the inner peripheral wall 5a, and a cylinder positioned on the outer side in the radial direction of the cylindrical wall 3e is provided at the outer edge portion of the flange portion 5c. An outer peripheral wall 5d is provided. Here, on the inner peripheral surface of the outer peripheral wall 5d, a female screw portion 5e that fits the male screw portion 3f is provided. A step wall 5f is provided at the lower end of the outer peripheral wall 5d, extending outward in the radial direction and then extending downward. Further, as shown in the enlarged view of FIG. 1 (b), the flange portion 5c is provided with an inner annular wall 5g that rises upward from its central portion, and the outer peripheral surface of the inner annular wall 5g has a diameter on the outer peripheral surface. A locking portion 5h that protrudes outward in the direction is provided. An outer annular wall 5j is provided on the radially outer side of the inner annular wall 5g.

  The discriminator 6 includes a disc-shaped inner top wall 6a and an outer top wall 6b that is located on the radially outer side of the inner top wall 6a and is integrally connected to the outer edge of the inner top wall 6a over the entire circumference. I have. On the lower surface of the inner top wall 6a, a downward projection 6c that protrudes toward the upper surface of the wall portion 4a is provided. Further, at the outer edge of the outer top wall 6b, as shown in the enlarged view of FIG. 1B, a side wall 6d extending downward and positioned between the inner annular wall 5g and the outer annular wall 5j. Is provided. And the nail | claw part 6e which protrudes toward radial inside and is hooked on the latching | locking part 5h is provided in the internal peripheral surface of the side wall 6d.

  The virgin ring 7 is provided between the base 3 and the cap 5. In the present embodiment, it is provided between the peripheral wall 3 g of the base 3 and the step wall 5 f of the cap 5. As shown in FIG. 2A, the virgin ring 7 of the present embodiment includes a ring main body 7a that surrounds the outer edge of the top wall 3a, and the inner peripheral surface of the ring main body 7a conforms to the convex portion 3j. A recess 7b is provided. Further, an arcuate finger-hanging portion 7c is provided on the radially outer side of the ring body 7a. As shown in FIG. 2 (a), the ring main body 7a is locally thin at the portion where the ring main body 7a and the finger hook 7c are connected. For this reason, if it pulls so that the finger-hanging part 7c may be reversed, the ring main body 7a can be fractured | ruptured from a thin part.

  In the mixing container 1 having such a configuration, the cap 5 is prevented from moving downward by the virgin ring 7 described above. That is, it is possible to prevent a problem that the cap 5 moves inadvertently during distribution.

  When the second agent is introduced, first, an operation for removing the virgin ring 7 is performed. In the present embodiment, the virgin ring 7 can be removed because the thin portion of the ring main body 7a is broken by pulling the finger rest 7c. As shown in FIG. 2 (a), the ring body 7a is fitted to the recess 7b, and even if the ring body 7a is pulled so as to invert the finger hook 7c, There is no rotation. For this reason, even if the force applied to the finger-hanging portion 7c is small, the thin portion can be broken.

  Thereafter, the cap 5 is rotated in such a direction that the male screw portion 3f and the female screw portion 5e are tightened. As a result, the cap 5 moves downward toward the base 3 as shown in FIG. At this time, since the filler 4 connected to the cap 5 by the connecting piece 5b also moves downward while rotating, the seal portion 4b is broken by the blade portion 3c. Thereby, since the 2nd agent flows out of filling space S2 and is introduced into storage space S1 through communicating port 3b, the 1st agent and the 2nd agent can be mixed.

  Further, by rotating the cap 5 in such a direction that the male screw portion 3f and the female screw portion 5e are tightened, the lower end portion of the wall portion 4a comes into contact with the upper surface of the top wall 3a and the wall portion 4a stays at that position, while the cap 5 Moves downward, a relatively upward force acts on the filler 4. Therefore, as shown in FIG. 2B, the filler 4 moves upward with respect to the cap 5 while inverting the connecting piece 5 b. As a result, an upward force also acts on the identification body 6 that has been in contact with the upper surface of the wall portion 4 a, the engagement between the locking portion 5 h and the claw portion 6 e is released, and the identification body 6 is removed from the cap 5. take off. That is, since the identification body 6 falls off as the second agent is introduced, whether or not the second agent is introduced can be determined depending on whether or not the identification body 6 remains in the cap 5. By the way, when holding the identification body 6 in the cap 5, in order to prevent the identification body 6 from dropping before the seal portion 4b is broken, it is compared with the resistance force when the seal portion 4b is broken. Thus, the holding force of the identification body 6 held by the cap 5 is set high. When the identification body 6 is held on the cap 5 by the locking portion 5h and the claw portion 6e as in the present embodiment, the identification body 6 can be held with a somewhat strong holding force, and therefore the seal portion 4b. It is possible to effectively prevent the problem that the identification body 6 falls off before the rupture is broken. In order to hold the identification body 6 in the cap 5, various methods such as a configuration in which the side wall 6d is press-fitted into the inner annular wall 5g can be employed.

  Next, 2nd Embodiment of the mixing container according to this invention is described, referring FIGS. 3-4. The mixing container 11 of the present embodiment includes an identification body 16 instead of the above-described identification body 6.

  The discriminator 16 includes a disc-shaped inner top wall 16a and an outer top wall 16b positioned on the radially outer side of the inner top wall 16a. Here, between the inner top wall 16a and the outer top wall 16b, there is provided a weakening portion 16f that intermittently connects them in the circumferential direction. The weakened portion 16f only needs to connect the inner top wall 16a and the outer top wall 16b so that they can be broken. For example, the weakened portion 16f can be thinned so that the inner top wall 16a and the outer top wall 16b extend over the entire circumference. You may connect. The identification body 16 includes a downward projection 16c, a side wall 16d, and a claw portion 16e having the same configuration as the downward projection 6c, the side wall 6d, and the claw portion 6e described above.

  Even in the mixing container 11 having such a configuration, when the second agent is introduced, first, an operation of removing the virgin ring 7 is performed. When the cap 5 is tightened, the seal portion 4b is broken by the blade portion 3c, the second agent flows out from the filling space S2, and can be mixed with the first agent in the accommodation space S1 through the communication port 3b. .

  Further, when the cap 5 is tightened, the lower end portion of the wall portion 4a comes into contact with the upper surface of the top wall 3a, and the filling body 4 moves upward with respect to the cap 5, and is pushed onto the downward projection 16c of the identification body 16. Therefore, an upward force acts on the inner top wall 16a. As a result, the weakened portion 16f breaks and the inner top wall 16a falls off. That is, in the present embodiment, it is possible to determine whether or not the second agent has been charged depending on whether or not the inner top wall 16a has fallen off. Furthermore, in the identification body 16 of the present embodiment, the weakened portion 16f breaks and the inner top wall 16a falls off, so that the inner top wall 16a cannot be attached to the cap 5 again. For this reason, there is no state in which the inner top wall 16a remains even though the second agent is charged, and it is possible to always correctly determine whether or not the second agent is charged.

  In the mixing container according to the present invention, still another embodiment is possible. 5 to 6 show a third embodiment of the mixing container according to the present invention. The mixing container 21 of this embodiment is provided with an identification body 26 instead of the identification body 6 of the first embodiment.

  The identification body 26 includes an inner top wall 26a, an outer top wall 26b, a downward projection 26c, and a side wall having the same configuration as the inner top wall 6a, the outer top wall 6b, the downward projection 6c, the side wall 6d, and the claw portion 6e described above. 26d and a claw portion 26e. Here, as shown in the enlarged view of FIG. 5 (b) and FIG. 6 (b), the side wall 26d is provided with a recess 26g partially cut away from the side wall 26d. The upper part is integrally connected to the side wall 26d, and an elastic piece 26h is provided that spreads radially outward as it goes downward. A total of eight elastic pieces 26h of the present embodiment are provided at equal intervals in the circumferential direction. When attaching the identification body 26 to the cap 5 at the time of assembly, for example, the elastic pieces 26h are all bent inward by, for example, an annular jig, and in this state, between the inner annular wall 5g and the outer annular wall 5j. The side wall 26d may be inserted.

  Even in the mixing container 21 having such a configuration, first, an operation of removing the virgin ring 7 is performed. When the cap 5 is tightened, the seal part 4b is broken by the blade part 3c, and the second agent flowing out from the filling space S2 is introduced into the accommodation space S1 through the communication port 3b and mixed with the first agent.

  Further, when the cap 5 is tightened, the lower end portion of the wall portion 4 a comes into contact with the upper surface of the top wall 3 a and the filler 4 moves upward with respect to the cap 5. As a result, the upper surface of the wall portion 4a presses against the downward projection 26c, so that an upward force also acts on the identification body 26, the engagement between the locking portion 5h and the claw portion 26e is released, and the identification body 26 is released. Falls off the cap 5. That is, also in the present embodiment, it is possible to determine whether or not the second agent has been introduced depending on whether or not the identifier 26 remains in the cap 5. Furthermore, the identification body 26 of the present embodiment is detached from the cap 5 so that the elastic piece 26h is restored in the direction away from the side wall 26d as shown in FIG. 6B. Therefore, the identification body 26 is attached to the cap 5 again. Even if it tries, the elastic piece 26h will interfere with the outer side annular wall 5j. For this reason, the reattachment of the identification body 26 is prevented, and the presence / absence of the second agent can always be correctly determined.

  The mixing container according to the present invention is not limited to the embodiments described so far, and includes those modified in various ways within the scope of the claims. For example, the cap 5 is not limited to the one that moves downward by a screw as in the above-described embodiment. For example, the base 3 is provided with a groove extending in the vertical direction, and the cap 5 is provided with a convex portion that matches the groove. It may be configured to move downward by sliding. Further, in the embodiment described above, the locking portion 5h is provided on the inner annular wall 5g, but this is provided on the outer annular wall 5j, and the claw portions 6e, 16e, 26e of the identification bodies 6, 16, 26 are provided.
