  However, the multi-chamber container proposed in Patent Document 1 is a container for mixing solids and liquids, and has a complicated shape. Therefore, when the contents stored in each storage space are mixed and the mixed mixture is discharged, the mixture may remain in the vicinity of a portion where one storage space and the other storage space are connected. Moreover, in this multi-chamber container, since the storage space is configured by a curved surface, when the mixed liquid is discharged, wrinkles are generated in the storage space and the contents remain.

  The multi-chamber container proposed in Patent Document 2 is formed by laminating a flat soft material. Also in this multi-chamber container, when the contents stored in the respective storage chambers are mixed and the mixed liquid is discharged, the contents remain in the peripheral portion of the storage chamber.

  The present invention has been made to solve the above-mentioned problems, and its purpose is to greatly reduce the amount of the mixture remaining in the storage chamber after the mixture formed by mixing the contents in each storage chamber is discharged. The object is to provide a multi-chamber container that can be reduced.

  The multi-chamber container according to the present invention for solving the above-described problem is formed by sealing two sheet materials each including a base material layer and a barrier layer, and at least one of the two sheet materials. The material is configured as a container main body formed with a plurality of storage chambers protruding from the one surface side to the other surface side, and the other sheet material is covered on the one surface side of the one sheet material, The storage chamber is configured as a lid member that is closed, and a high-strength seal portion in which the container body and the lid member are sealed with relatively high strength is formed outside the storage chamber, and the storage chamber Between the two, the container main body and the lid member are sealed with relatively low strength, and the container main body and the lid member are peeled off to form a low-strength seal portion that allows the storage chambers to communicate with each other. The lid member includes the one of the container body. Sealant layer is provided on a surface in contact with the side, on the bottom surface of the accommodating chamber, a polygonal line for bending the bottom surface, and wherein the extending direction of the accommodating chamber is contiguous.

  According to the present invention, a high-strength seal portion in which the container main body and the lid member are sealed with relatively high strength is formed outside the storage chamber, and the container main body and the lid member are provided between the storage chambers. Is sealed with a relatively low strength, and the container body and the lid material are peeled off to form a low-strength seal that allows the storage chambers to communicate with each other. Thus, the container main body and the lid member can be peeled only at the position of the low-strength seal portion, the storage chambers can be communicated with each other, and the contents respectively stored in the plurality of storage chambers can be mixed. When discharging the mixture produced by mixing the contents, the folding line for folding the bottom surface extends in the direction in which the accommodation chambers are connected. And can be made into a folded form. As a result, the mixture can be prevented from remaining in the storage chamber, and the mixture can be effectively discharged.

  In the multi-chamber container according to the present invention, the lid member may be formed of a flat sheet member.

  According to this invention, the volume of the storage chamber closed by the container main body and the lid member is larger than that in the case of using the lid member formed with a plurality of convex portions protruding from the one surface side to the other surface side. Can be small. Therefore, it can be set as the multi-chamber container suitable for accommodation of a small amount of contents.

  In the multi-chamber container according to the present invention, the storage chamber may be composed of a plurality of planes, and an angle formed between adjacent planes may be a right angle or an obtuse angle.

  According to this invention, it is composed of a plurality of planes forming the storage chamber, and the angle between the adjacent planes is set to a right angle or an obtuse angle, so that wrinkles can be prevented from entering the sheet material of the storage chamber at the time of overlapping folding. The residual amount of contents can be greatly reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The technical scope of the present invention is not limited only to the following description and drawings.

[overall structure]
As shown in FIGS. 1 to 3, the multi-chamber container 1 according to the present invention is configured by sealing two opposing sheet materials. At least one of the two sheet materials is configured as a container body 10 in which a plurality of storage chambers 11 are formed so as to protrude from one surface side to the other surface side, and the other sheet material is a container body. 10 is configured as a lid member 20 that covers one surface of one sheet material configured as 10 and closes the plurality of storage chambers 11. In the multi-chamber container 1 shown in FIGS. 1 to 3, the other sheet material configured as the lid material 20 is configured by a flat sheet material. “Flat” means that there are no projections or depressions in the thickness direction of the sheet material.

  However, the multi-chamber container 1 has a form using a lid member 20 in which a storage chamber 11 that protrudes from one side to the other side is formed in addition to the form shown in FIGS. 1 to 3. That is, the multi-chamber container 1 has two forms, that is, a form in which the storage chamber 11 is provided only in the container main body 10 and a form in which the storage chamber 11 is provided in both the container main body 10 and the lid member 20.

  A high-strength seal portion 31 in which the container body 10 and the lid member 20 are sealed with relatively high strength is formed outside the storage chamber 11. “Sealed with relatively high strength” means a region excluding the portion between the storage chambers 11 with respect to the strength at which the container body 10 and the lid member 20 are sealed at the portion between the storage chambers 11. This means that the strength of sealing the container body 10 and the lid member 20 is high. Further, the container main body 10 and the lid member 20 are sealed with relatively low strength between the storage chambers 11, and the container main body 10 and the lid member 20 are peeled off so that the storage chambers 11 communicate with each other. A seal portion 32 is formed. “Sealed with a relatively low strength” means a portion between the storage chambers 11 with respect to the strength at which the container body 10 and the lid member 20 are sealed in a region excluding the portion between the storage chambers 11. This means that the strength with which the container body 10 and the lid 20 are sealed is low. In addition, the term “communication” as used herein refers to a space formed by separating the container body 10 and the lid 20 at the position of the low-strength seal portion in the storage chamber isolated by the low-strength seal portion. It means to be in a continuous state. A peripheral surface 15 that is perpendicular to or substantially perpendicular to the lid member 20 is formed at a portion corresponding to the high-strength seal portion 31 on the periphery of the storage chamber 11.

  Further, as shown in FIG. 1, the multi-chamber container 1 is formed so that the width of the portion corresponding to the low-strength seal portion 32 is narrower than the width of the portion corresponding to the storage chamber 11. Furthermore, an opening start portion 40 is formed at a position corresponding to the low-strength seal portion 32 on the side portion of the multi-chamber container 1.

  When necessary, the multi-chamber container 1 causes the container main body 10 and the lid member 20 to be peeled at the position of the low-strength seal portion 32 so that the storage chambers 11 communicate with each other. Next, the contents stored in the storage chambers 11 are mixed to generate a mixture. Thereafter, the multi-chamber container 1 is torn and opened in the width direction of the multi-chamber container 1 in a form in which the side edge of the multi-chamber container 1 and the low-strength seal portion 32 are connected at the position of the low-strength seal portion 32, and then opened The mixture is discharged from the position. Therefore, in order to make it easier to open the multi-chamber container 1 at the position of the low-strength seal portion 32, as shown in FIG. 1, an opening start portion 40 is formed in a portion corresponding to the low-strength seal portion 32, The width of the portion corresponding to the low-strength seal portion 32 where the opening start portion 40 is formed is narrow. However, it is not essential to narrow the width of the portion where the opening start portion 40 is formed, and the width of the portion corresponding to the low-strength seal portion 32 and the width of the portion corresponding to the storage chamber 11 are formed to be the same width. May be.

  Further, it is not essential to provide the opening start portion 40 at a position corresponding to the low-strength seal portion 32. The opening start part 40 is provided, for example, on the side of the part corresponding to the storage chamber 11 or on the end of the multi-chamber container 1 in the longitudinal direction so that the peripheral edge of the multi-chamber container 1 and the storage chamber 11 are connected. You may make it cut in the form which connects.

  Examples of the opening start portion 40 include notches such as an I notch, a V notch and a U notch, and a rough surface processed portion made of a group of fine holes.

  Each of the storage chambers 11 stores a liquid, the storage chamber 11 stores a liquid, and the other storage chamber 11 stores a powder. It is done. Moreover, the mixture produced | generated by mixing the contents in each storage chamber 11 is a liquid or a jelly-like substance.

  According to the multi-chamber container 1 according to the present invention, the amount of the mixture remaining in the storage chamber 11 after the mixture formed by mixing the contents in each storage chamber 11 is discharged can be greatly reduced. There is a specific effect that the contents stored in the storage chamber 11 can be used up efficiently. In particular, the multi-chamber container 1 effectively suppresses the mixture from remaining in the storage chamber 11 when the mixture produced by mixing the contents is a highly viscous liquid or jelly-like substance. be able to.

  Hereinafter, each structure of the multi-chamber container 1 which concerns on this invention is demonstrated concretely.

[Container body]
The container main body 10 includes a plurality of storage chambers 11 as shown in FIGS. 1 to 3. 1 and 2 show an example of a multi-chamber container 1, and a container body 10 of the multi-chamber container 1 includes two storage chambers 11. The container body 10 is composed of two storage chambers 11 projecting from one side of the container body 10 toward the other side, and a flat flange projecting toward the outside of the container body 10 outside the storage chamber 11. Part 13. Further, the 10 parts of the container body has a flat surface 12 formed between the two storage chambers 11. The flange portion 13 is configured as a high-strength seal portion 31 that is sealed with relatively high strength to the lid member 20 described later, and the flat surface 12 formed between the storage chambers 11 is relatively to the lid member 20. It is configured as a low-strength seal portion 32 that is sealed with low strength.

  As shown in FIG. 2, the storage chamber 11 has a shape in which a part of the sheet material protrudes from the one surface side toward the other surface side. In other words, as for the cross-sectional shape of the sheet material, one surface (one surface side) has a concave shape, and the other surface (the other surface side) has a convex shape. A space is formed on one side of the protruding portion, and the contents are accommodated in this space.

  A fold line 18 for bending the bottom surface 16 extends in a direction in which the storage chambers 11 are connected to the bottom surface 16 constituting each storage chamber 11. The broken line 18 is a structure for folding the bottom surface 16 when the contents stored in the storage chamber 11 are discharged.

  As shown in FIGS. 1, 3, and 4, the broken line 18 connects the outer end of each storage chamber 11 and the center end of the multi-chamber container 1 in the direction in which the storage chambers 11 are connected. Is formed. In the example of the multi-chamber container 1 shown in FIGS. 1, 3, and 4, a broken line 18 is formed at the center position in the width direction of the multi-chamber container 1. The width direction of the multi-chamber container 1 is a direction orthogonal to the direction in which the storage chambers 11 are connected.

  As shown in FIG. 3, the bottom surface 16 is configured as a surface in which the position of the polygonal line 18 is located on the outermost side and the space between the polygonal line 18 and the peripheral surface 15 is inclined. In other words, the bottom surface 16 is bent at the position of the broken line 18, and the position of the broken line 18 forms the top of the bottom surface 16.

  In the example of the multi-chamber container 1 shown in FIGS. 1, 3, and 4, a broken line 18 is formed on the inclined surface 17 in addition to the bottom surface 16 of each storage chamber 11. The inclined surface 17 is an inclined surface provided closer to the center of the multi-chamber container 1 than the bottom surface 16 of each storage chamber 11. The broken line 18 formed on each inclined surface 17 is formed at a position that is aligned with the broken line 18 formed on each bottom surface 16 in the width direction of the multi-chamber container 1. Specifically, the polygonal line 18 of the inclined surface 17 connects the bottom surface 16 of the storage chamber 11 and the flat surface 12 provided at the center of the multi-chamber container 1 at the center position in the width direction of the multi-chamber container 1. It is out. Similarly to the polygonal line 18 formed on the bottom surface 16, the polygonal line 18 formed on the inclined surface 17 is also formed on the inclined surface 17 when the contents accommodated in the storage chamber 11 are discharged. It is the structure for folding in position.

  The storage chamber 11 is formed by deep drawing using a mold. As a deep drawing method, for example, a method of pressing the multilayer sheet 10a using the male mold 51 and the female mold 52 shown in FIG. The method etc. which attract | suck the sheet | seat 10a to a female type | mold can be mentioned. When the multilayer sheet 10a is pressed using the male mold 51 and the female mold 52, for example, deep drawing is performed as shown in FIG. That is, the multi-layer sheet 10a is pressed by the male mold 51 from one side to the other side where the female mold 52 is disposed, thereby forming the storage chamber 11.

  When the storage chamber 11 is formed by pressing the multilayer sheet 10a using the male mold 51 and the female mold 52, the bottom surface 16 of the storage chamber 11 and the broken line 18 of the inclined surface 17 are formed simultaneously. . As shown in FIG. 5, the male mold 51 is configured such that a center 51 a at the tip protrudes outward, and both sides of the center 51 a are inclined. On the other hand, the female mold 52 has a depressed center 52a at the bottom, and both sides of the center 52a are inclined.

  When the multilayer sheet 10a is pressed by such a male mold 51 and a female mold 52, the center 51a of the male mold 51 and the center 52a of the female mold 52 are aligned. As a result, a polygonal line 18 is formed in the multilayer sheet 10a.

The volume of the storage chamber 11 is not particularly limited, and the storage chamber 11 is formed according to the capacity of the contents stored in the storage chamber 11. However, when the absolute capacity of the contents is small, when a certain amount of the mixture obtained by mixing the contents accommodated in each accommodation chamber 11 remains in the accommodation chamber 11 without being discharged from the multi-chamber container 1. The ratio of the remaining amount to the total amount of the mixture is increased. Therefore, when the content volume is relatively small, it is more important to reduce the remaining amount than when the content volume is relatively large. In the container main body 10 of this embodiment, the volume of the storage chamber 11 is formed so as to be applied to a volume with a small content. Specifically, the volume of the storage chamber 11 is 1 cm ³ or more and 30 cm ³ or less.

  As for said container main body 10, the storage chamber is comprised by the several plane, and the angle formed by adjacent planes has comprised the right angle thru | or the obtuse angle.

  Specifically, as shown in FIG. 2, an angle θ formed by the rear portion of the peripheral surface 15 and the high-strength seal portion 31 forming the outside thereof, an angle θ formed by the rear portion of the peripheral surface 15 and the bottom surface 16, The angle θ formed by the bottom surface 16 and the inclined surface 17 and the angle θ formed by the inclined surface 17 and the low-strength seal portion 32 form a right angle or an obtuse angle. Similarly, as shown in FIG. 3, the angle θ formed between the side portion of the peripheral surface 15 and the high-strength seal portion 31 forming the outside thereof, and the angle formed between the side portion of the peripheral surface 15 and the bottom surface 16. θ is a right angle or an obtuse angle. Further, the bending angle θ formed by the bottom surface 16 forming both sides of the broken line 18 is also a right angle or an obtuse angle.

  When said angle (theta) is an obtuse angle, there is no limitation in particular in the magnitude | size of the angle. In particular, the bending angle θ is preferably smaller than 180 degrees and within a range of 170 degrees or less. However, the bending angle θ may be formed to be smaller than 170 degrees.

  The container body 10 having the above-described configuration described above is configured by a multilayer sheet including a base material layer and a barrier layer.

  The base material layer preferably has mechanical strength such as tensile strength, impact strength, and scratch resistance required in normal applications. The base material layer may be a film material or sheet material having a single layer structure or a film material or sheet material having a multilayer structure as long as it has such properties. As a material for the base material layer, for example, polyolefin such as chain polyolefin and cyclic polyolefin is used. Examples of the polyolefin include polyethylene or polypropylene.

  The barrier layer has an oxygen barrier property and a water vapor barrier property. As the material for the barrier layer, it is possible to use a stretched sheet such as polyester such as polyethylene terephthalate or polyamide, or an organic material such as ethylene-vinyl alcohol copolymer, polyvinylidene chloride (PVDC), or polychlorotrifluoroethylene (PCTFE). it can. In addition, as a material for the barrier layer, an inorganic material such as aluminum foil or vapor-deposited silica can be used. In particular, PVDC or PCTFE is preferably used as the barrier layer used for the multilayer sheet of the container body 10.

  The multilayer sheet is formed, for example, by sandwiching a material configured as a barrier layer between resins configured as resin layers and co-extrusion.

  The multilayer sheet constituting the container body 10 can be provided with an unstretched nylon layer in addition to the resin layer and the barrier layer. By providing an unstretched nylon layer, the stretchability of the multilayer sheet can be improved.

  The container main body 10 composed of a multilayer sheet preferably has a thickness of the storage chamber 11 of 400 μm or less. As described above, the storage chamber 11 is formed by deep drawing a multilayer sheet. The portion of the storage chamber 11 formed by deep drawing is slightly thinner than the other portions of the multilayer sheet. For this reason, even if the thickness of the multilayer sheet itself exceeds 400 μm, it is sufficient that the thickness of the portion of the storage chamber 11 is 400 μm or less after being formed by deep drawing. The lower limit of the thickness is not limited, but is preferably 100 μm or more.

  When the thickness of the storage chamber 11 portion of the container body 10 exceeds 400 μm, the flexibility of the storage chamber 11 is slightly lowered. Therefore, it becomes difficult to slide the finger from one storage chamber 11 toward the other storage chamber 11 in a state where the storage chamber 11 is pressed and crushed. In other words, it becomes difficult to squeeze the storage chamber 11 with a finger. On the other hand, when the thickness of the portion of the storage chamber 11 of the container body 10 is 400 μm or less, the storage chamber 11 is formed flexibly. Therefore, when the contents stored in the storage chambers 11 are mixed with each other, the storage chamber 11 can be easily crushed with a finger, and the fingers can be crushed from one storage chamber 11 to the other storage chamber 11. It can be easily slid toward. In other words, the storage chamber 11 can be easily rubbed with a finger.

[Cover material]
The lid member 20 is composed of a multilayer sheet including a base material layer, a barrier layer, and a sealant layer.

  The base material layer is composed of a resin film. Examples of the resin film include a biaxially stretched polyethylene terephthalate (O-PET) film, a biaxially stretched nylon (O-Ny) film, and a biaxially stretched polypropylene (O-PP) film. Moreover, what laminated | stacked polyolefin etc. on paper other than the resin film can also be used for a base material layer.

  The barrier layer has an oxygen barrier property and a water vapor barrier property. As the barrier layer, for example, a metal foil or a vapor deposition layer can be used. As the metal foil, an aluminum foil can be preferably used. Moreover, as a vapor deposition layer, the vapor deposition layer of aluminum or an inorganic oxide can be used preferably. As the barrier layer, an ethylene-vinyl alcohol copolymer (EVOH), vinylidene chloride, or the like can be used in addition to the metal foil and the vapor deposition layer.

  The sealant layer is configured as an easy peel layer. As a material constituting the easy peel layer, for example, a polypropylene resin, a mixed resin of a polyester resin and a polyethylene resin can be used.

[Seal between container body and lid]
The container body 10 and the lid member 20 are sealed by heat sealing. A method for forming the high-strength seal portion 31 having a relatively high seal strength and the low-strength seal portion 32 having a relatively low seal strength is not particularly limited. For example, when sealing the container body 10 and the lid member 20, the pressure for pressing the container body 10 and the lid member 20 by the sealing means is changed, the temperature for crimping is changed, or the number of times of crimping is changed. The high-strength seal portion 31 and the low-strength seal portion 32 are formed respectively. That is, the high-strength seal part 31 presses the container body 10 and the lid member 20 with a higher pressure than the low-strength seal part 32, or presses the container under a high temperature, or increases the number of times it is pressed. Formed by.

  The seal strength of the high-strength seal portion 31 is preferably, for example, 10 N / 15 mm or more, more preferably 15 N / 15 mm or more, and the seal strength of the low-strength seal portion 32 is, for example, 5 N / 15 mm or less, and further preferably 2 N / 15 mm or less.

  Since the container body 10 and the lid member 20 are sealed by heat-sealing, the shape to be sealed can be freely set, and the width of the low-strength seal portion 32 indicated by the symbol H in FIG. Can be formed to dimensions. The seal shape is set by changing the width of the roller used for heat sealing or the shape of the seal bar.

[Operation of multi-chamber container]
In this multi-chamber container 1, the contents accommodated in the respective accommodating chambers 11 are mixed to generate a mixture, and the generated mixture is discharged from the multi-chamber container 1 to the outside.

  When mixing the contents of the storage chambers 11, one or both of the storage chambers 11 is compressed by hand to increase the internal pressure of the storage chamber 11. When the internal pressure of the storage chamber 11 increases, a force is applied in a direction in which the container body 10 and the lid member 20 are separated. Since the low-strength seal portion 32 provided between the storage chamber 11 and the storage chamber 11 has a lower seal strength than the high-strength seal portion 31, the container body 10 and the lid member 20 are the low-strength seal portion 32. Peel off. That is, before the internal pressure of the storage chamber 11 rises, the container body 10 and the lid member 20 are sealed by the low-strength seal portion 32 as shown in FIG. When the internal pressure of the storage chamber 11 rises, as shown in FIG. 6B, the container body 10 and the lid member 20 are peeled and separated by the low-strength seal portion 32. On the other hand, in the high-strength seal portion 31, the sealed state between the container body 10 and the lid member 20 is maintained. Therefore, the storage chamber 11 and the storage chamber 11 are communicated with each other at the low-strength seal portion 32.

  After the storage chambers 11 communicate with each other at the position of the low-strength seal portion 32, the finger is slid toward the other storage chamber 11 while holding the one storage chamber 11 with a finger, and the contents in each storage chamber 11 are moved. Mix together.

  Thereafter, the multi-chamber container 1 is cut so as to cross the low-strength seal portion 32 at the position of the low-strength seal portion 32, and the multi-chamber container 1 is opened. After opening, the generated mixture is discharged to the outside from the position of the cut low-strength seal portion 32. In this multi-chamber container 1, the opening start portion 40 is provided on the periphery of the multi-chamber container 1, and the multi-chamber container 1 can be torn and opened from the opening start portion 40. 10 can be opened without peeling.

  When the mixture is discharged from the multi-chamber container 1, the mixture is discharged as follows in the multi-chamber container 1 in which the broken line 18 is formed on the bottom surface 16 and the inclined surface 17 of the storage chamber.

  In the multi-chamber container 1 in which the broken line 18 is formed, as shown in FIG. 7, the storage chamber 11 is bent at the position of the broken line 18 so that the broken line 18 protrudes outward. When the storage chamber 11 is bent at the position of the broken line 18, the lid member 20 is folded inward at a position 21 corresponding to the broken line 18. As a result, the inner surface of the lid member 20 and the inner surface of the housing portion 11 are opposed to each other or overlapped. Moreover, only the relative position of the thickness direction of the multi-chamber container 1 moves between the broken line 18 and the position 21 corresponding to this broken line 18, and the position of both width direction is maintained as it is. The folded storage chamber 11 is crushed by hand, and the mixture is moved from the position of the cut low-strength seal portion 32 by moving the hand toward the low-strength seal portion 32 cut from the end side of the storage chamber 11. It can be discharged.
