Description

  The present invention relates to a multi-chamber container having a plurality of storage chambers and capable of mixing the contents of the respective storage chambers as necessary.

  Conventionally, a container having a plurality of storage chambers is known in order to store a preparation or the like to be mixed and used at the time of use (Patent Documents 1 to 4).

  The containers described in Patent Documents 1 and 2 are formed by forming two storage chambers with a fold between sandwiched foldable substrates, and tearing a part of the substrate and taking out the contents of the two chambers when in use. It is configured to mix outside the container.

The containers described in Patent Documents 3 and 4 are formed by bonding two members together to form a plurality of storage chambers, and forming a weak seal portion that can be peeled between the two chambers, and peeling the weak seal portion during use. The contents can be mixed inside.
Japanese Utility Model Publication No. 6-49381 (FIGS. 1 to 3) JP 2002-128040 (FIGS. 1 to 5) JP-A-11-227843 (FIGS. 1 to 5) JP 2002-160771 (FIGS. 1 to 4)

  The problem that the containers described in Patent Documents 1 and 2 must be mixed outside the container can be solved by the container described in Patent Documents 3 and 4, but is described in Patent Documents 3 and 4. However, there is a problem that the manufacturing process of the container and the product manufacturing process such as content injection become complicated and the cost becomes high. In addition, there is a problem that it is difficult to handle because operations such as crushing one storage chamber are necessary for mixing the contents.

  Accordingly, a first object of the present invention is to facilitate handling for mixing and simplify a product manufacturing process in a multi-chamber container capable of mixing contents inside the container.

  Furthermore, the second object of the present invention is to provide an easily manufactured multi-chamber container that is completed simultaneously with the achievement of the first object.

The first invention made to achieve the first object is as follows:
(1-0) A plurality of compartments are provided in a synthetic resin container body formed by blow molding, and the contents stored in the compartments are mixed in the container body as necessary. A multi-chamber container that can be constructed and has the following configuration.
(1-1) The container body has mouths at both ends, has a constriction part in the middle, and can be bent at the constriction part.
(1-2) The fitting part for maintaining the state bent by the said constriction part is provided in the outer surface of a container main body.
(1-3) The constricted portion is formed so that the inner walls are in close contact with each other when the fitting portion is fitted.

  According to the multi-chamber container of the first aspect of the invention, when the container is bent at the constricted portion and the fitting portion is fitted by providing the above-described configurations (1-0) to (1-3). The container body is divided by the constricted portion to form a plurality of compartments. Since the container body is provided with mouths at both ends, each compartment formed by being divided at the constricted portion has a mouth. Therefore, liquid, powder or the like to be stored in each compartment is injected from this port. After storing the contents, close the mouth of each compartment. In the folded state, the inner walls of the constricted portion are in close contact with each other, so that even if different types of contents are stored in the respective compartments, they are not mixed. On the other hand, when the fitting part is unfitted and the container body is extended, the compartments communicate with each other through the constricted part. As a result, the contents can be mixed in the container body. After that, open the mouth and take out the contents for use. It should be noted that a detachable cap may be used for the extraction port. The other mouth may be closed by heat sealing.

Similarly, the second invention made to achieve the first object is as follows:
(2-0) A plurality of compartments are provided in a synthetic resin container body formed by blow molding, and the contents stored in the plurality of compartments are mixed in the container body as necessary. A multi-chamber container that can be constructed and has the following configuration.
(2-1) The container body has a mouth at least at one end, and is provided with a constriction part in the middle, and can be bent at the constriction part.
(2-2) The fitting part for maintaining the state bent by the said constriction part is provided in the outer surface of a container main body.
(2-3) The constricted part is formed so that the inner walls are in close contact with each other in a state where the fitting part is fitted.
(2-4) The said container main body shall be divided | segmented into the length direction by the division wall extended from this constriction part to the said mouth in the one side of the said constriction part.

  According to the multi-chamber container of the second invention, by providing the above (2-0) to (2-4), similarly to the first invention, the container is bent at the constricted part, and the fitting part is formed. When in the fitted state, the container body is divided by the constricted portion to form a plurality of compartments. At this time, one of the compartments is further divided by a partition wall. If there is one partition wall, it can be divided into two chambers, and if it is two, it can be divided into three chambers. The second invention is (a) a usage method in which three or more kinds of contents are mixed as required by injecting the contents into each compartment formed by bending at the constricted portion, and (b) the compartment. There is a usage method in which nothing is poured into the compartment on the side not provided with the wall, and it functions as a mixing chamber. In the case of the usage method (b), by providing the compartment functioning as a mixing chamber, even if the sealing due to the close contact between the inner walls of the constricted portions is insufficient, mixing of the contents hardly occurs. This is because the air in the mixing compartment suppresses the leakage of the contents, and even if it leaks, the air remains in the mixing compartment. In addition, heat sealing is simple as a method of closing the mouth after storing the contents, and it is more suitable for exhibiting the mixing prevention effect by the partition wall. On the other hand, an outlet for taking out the contents after mixing is provided on the side which becomes the mixing compartment. In this case, the take-out port may be a detachable cap, or may be formed by providing a knob that can be easily threaded. A structure including a knob that can be easily twisted is more preferable in that a multi-chamber container can be formed by only one step of blow molding.

In addition, the third invention, which is made energetically from the first invention and achieves the second object,
(3-0) A multi-chamber container including a plurality of compartments in a synthetic resin container body formed by blow molding, and having the following configuration.
(3-1) The container body has mouths at both ends, is provided with a constriction part in the middle, and can be bent at the constriction part.
(3-2) The fitting part for maintaining the state bent by the said constriction part is provided in the outer surface of a container main body.
(3-3) The constricted portion is formed so that the inner walls are in close contact with each other when the fitting portion is fitted.

  The multi-chamber container of the third invention is the same as the multi-chamber container of the first invention when used for the purpose of performing internal mixing. However, for example, both ends have screw caps and the screw caps can be removed in the folded state to mix the contents outside the container, or only one screw cap can be removed to remove the contents of one side. It can also be used for the purpose of taking out and using only things. Of course, instead of using the screw cap type, a method may be adopted in which both ends are closed by heat sealing and the contents are taken out by scissors. For example, the soy sauce and mustard attached to Shumai may be stored separately, and only soy sauce or both soy sauce and mustard may be taken out according to preference. The fact that the container is easy to manufacture has sufficient effectiveness over the prior art.

The fourth invention, which is also made energetically from the first invention and achieves the second object,
(4-0) A multi-chamber container comprising a plurality of compartments in a synthetic resin container body formed by blow molding, wherein the multi-chamber container has the following configuration.
(4-1) The container body has a mouth at least at one end, and is provided with a constriction part in the middle, and can be bent at the constriction part.
(4-2) The fitting part for maintaining the state bent by the said constriction part is provided in the outer surface of a container main body.
(4-3) The constricted portion is formed so that the inner walls are in close contact with each other when the fitting portion is fitted.
(4-4) The said container main body shall be divided | segmented into the length direction by the division wall extended from this constriction part to the said mouth in the one side of the said constriction part.

  The multi-chamber container according to the fourth aspect of the invention can be used in the same manner as the second aspect of the invention if the fitting part is unfitted before the container is opened. The contents of each compartment can be taken out and mixed outside, or only a part of the contents can be taken out and used.

Also in these first to fourth inventions, it is preferable to have the following configuration.
(5) The fitting portion is composed of a convex portion in which a part of the outer wall of the container main body protrudes and a concave portion in which a part of the outer wall of the container main body is depressed.

  By using the unevenness of the outer wall as the fitting portion, the shape is more suitable for blow molding.

  The constricted portion may be constituted by a depression from the front or back surface of the container body and a depression from the side surface. By providing the depression from the side surface, it is possible to prevent a state in which the sealing performance is impaired due to bulging to the side when bent.

  As described above, according to the first and second inventions, the contents can be easily handled, and can be manufactured with a small number of processes by blow molding, and the contents can be easily injected. is there. In addition to the above effects, the third and fourth inventions can also be used for applications such as out-of-container mixing and removal of only a part of the contents. The same effect as the first and second inventions is exhibited.

  Embodiments of the present invention will be described below with reference to the drawings. First, the multi-chamber container 10 of 1st Embodiment corresponding to 1st, 3rd invention is demonstrated based on FIG. In the multi-chamber container 10 of the first embodiment, as shown in FIGS. 1A to 1C, as a container body 11, a heat sealing port 12 is provided at one end and a screw cap port 13 is provided at the other end. And having a constricted portion 14 in the middle. The container body 11 is manufactured by blow molding. Here, the constricted portion 14 is formed by a depression 14 a provided on the surface of the container body 11 and depressions 14 b and 14 b provided on the side surface of the container body 11. In addition, the back surface of the container body 11 has a flat shape, and a cylindrical convex portion 15 in which a part of the outer wall protrudes and a part of the outer wall are depressed in a symmetrical position with the constricted portion 14 in between. And a cylindrical recess 16. The convex portion 15 and the concave portion 16 can be fitted to each other, and once fitted, the convex portion 15 and the concave portion 16 function as a fitting portion having a size and shape so that the fitting cannot be released unless a certain amount of force is intentionally applied. The recesses 14a and 14b are sized and shaped so that the inner walls of the constricted portion 14 are in close contact with each other when the convex portion 15 and the concave portion 16 are fitted.

  According to the multi-chamber container 10 of the first embodiment, as shown in FIG. 1D, when the convex portion 15 and the concave portion 16 are fitted to each other by bending at the constricted portion 14, the container main body 11 is constricted. Divided by the section 14, two compartments of an A chamber 17 and a B chamber 18 are formed. Since the container body 11 is provided with the mouths 12 and 13 at both ends thereof, each of the compartments 17 and 18 formed by being divided by the constricted portion 14 has a mouth. Therefore, contents such as liquid and powder are injected into the A chamber 17 and the B chamber 18 from the ports 12 and 13. When the contents are injected, the heat sealing port 12 is closed by heat sealing. Further, the screw cap mouth 13 is closed with a screw cap.

  As shown in FIG. 1D, in the folded state, the inner walls of the constricted portion 14 are in close contact with each other, so that even if different types of contents are stored in the A chamber 17 and the B chamber 18, they may be mixed. Absent. On the other hand, when the container body 11 is extended by releasing the fitting, the A chamber 17 and the B chamber 18 communicate with each other through the constricted portion 14. In this state, by pushing the outer wall of the B chamber 18 on the side closed by heat sealing several times, the contents in the B chamber 18 can be pushed out to the A chamber 17 side to be in a two-component mixed state. . Since the container body 11 is made of blow molding, the mixing operation by pressing with such a finger is easy. After the contents are mixed together in this way, the screw cap is removed, the mouth 13 is opened, and the mixed contents are taken out and used. In the relationship with the third invention, the screw cap is removed and the contents are taken out in the bent state, and the heat-sealed mouth is cut with a pinch or the like to take out the contents for use.

  Next, the multi-chamber container 20 of 2nd Embodiment corresponding to 2nd, 4th invention is demonstrated based on FIG. In the multi-chamber container 20 of the second embodiment, as shown in FIGS. 2 (A) to (C), as the container body 21, a heat sealing port 22 is provided at one end and a threaded knob 23 is provided at the other end. In addition, a device having a constricted portion 24 in the middle is employed. The container body 21 is further divided in the length direction by a partition wall 25 extending from the constricted portion 24 to the heat sealing port 22. As a result, two heat sealing ports 22 a and 22 b are formed at the upper end of the container body 21. The container body 21 is manufactured by blow molding. The constricted portion 24 is formed by a recess 24 a provided on the back surface of the container body 21 and recesses 24 b and 24 b provided on the side surface of the container body 21. In addition, the container body 21 includes a recess 21 a on the surface above the constricted portion 24 that can receive a portion below the constricted portion 24. A cylindrical convex portion 26 is formed in the recess 21 a of the container body 21 with a part of the outer wall protruding from the partition wall 25. In addition, a cylindrical concave portion 27 in which a part thereof is depressed is formed on an outer wall of a portion below the constricted portion 24 of the container main body 21. The concave portion 27 is provided at a position symmetrical to the convex portion 26 across the constricted portion 24. The convex portion 26 and the concave portion 27 can be fitted to each other, and once fitted, function as a fitting portion having a size and shape so that the fitting cannot be released unless a certain amount of force is intentionally applied. The recesses 24a and 24b are dimensioned and shaped so that the inner walls of the constricted portion 24 are in close contact with each other when the convex portion 26 and the concave portion 27 are fitted.

  According to the multi-chamber container 20 of the second embodiment, as shown in FIG. 2 (D), the container main body 21 is constricted when the convex portion 26 and the concave portion 27 are fitted to each other by being bent at the constricted portion 24. Divided by the section 24 and the partition wall 25, three partition chambers A chamber 28, B chamber 29, and chamber 30 are formed. The A chamber 28 and the B chamber 29 are provided with ports 22a and 22b, respectively. Therefore, contents such as liquid and powder are injected into the A chamber 28 and the B chamber 29 from the ports 22a and 22b. When the contents are injected, the ports 22a and 22b are closed by heat sealing.

  As shown in FIG. 2D, in the folded state, the inner walls of the constricted portion 24 are in close contact with each other and are sealed, so that different types of contents are stored in the A chamber 28 and the B chamber 29. But they never mix. On the other hand, when the container body 21 is extended by releasing the fitting, the A chamber 28, the B chamber 29, and the C chamber 30 communicate with each other through the constricted portion 24. In this state, the outer walls of the A chamber 28 and the B chamber 29 are pushed, and the respective contents are pushed out to the C chamber 30. As a result, a two-liquid mixed state can be achieved in the C chamber 30. Since the container body 21 is made of blow molding, the mixing operation by pressing with such a finger is easy. After the contents are mixed together in this way, the knob 23 is threaded to open the mouth of the C chamber 30, and the mixed contents are taken out and used. In relation to the fourth invention, the heat sealed mouth is opened and the contents are individually taken out and used in the folded state.

  According to each embodiment described above, since the constricted portions 14 and 24 are provided with the depressions 14b and 24b from the side surfaces, they do not swell laterally when bent and do not impair the sealing performance.

  In addition, according to the second embodiment, since the C chamber 30 functioning as a mixing compartment is provided, the air in the C chamber 30 prevents leakage of the contents of the A chamber 28 and the B chamber 29. Even if it leaks, the effect of staying in the leakage into the C chamber 30 is also exhibited.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the scope of the invention.

  For example, in the first embodiment, only one port is a screw cap type, but both may be a screw cap type, and conversely, both ports may be closed by heat sealing.
