JP 2011-08662A

  However, in the composite container as disclosed in Patent Document 1, the protruding portion 2204 is provided at the lower portion as shown in FIG. Further, the lower protrusion 2204 is useful only for maintaining the bag shape at the lower part. In FIG. 23, the bag 2202 protrudes from the sleeve 2201 also in the upper part, but the bag 2202 is easily deformed in the upper part because there is no support by the sleeve in the upper part. In particular, in a structure in which the weight is heavy such as pouring, in a structure in which the sleeve 2201 is not supported on the upper portion, the hot water is easily spilled due to deformation.

  In addition, it is difficult to form such a sleeve 2201 in a band shape in advance like gluing, and the sleeve has a first surface 2205 and a second surface 2206 on both sides of a back surface (not shown). It is connected, and the engagement portion 2208 of the first surface 2205 and the engagement portion 2207 of the second surface 2206 are engaged to form a band. However, it is difficult to easily form the band. In some cases, the engagement may be released if not completely engaged.

  When the content is heavy, such a simple configuration may not be able to bear the weight. In particular, in the case of a usage method in which the weight of the contents is increased so as to pour, there is a possibility that what has been appropriately engaged may be disengaged by the pouring, and particularly in the case of pouring, an accident is likely to occur. .

  According to a first aspect of the present invention, there is provided a sleeve having a front surface and a back surface connected at both ends, and a bag having a front surface and a back surface which can be stored in the sleeve connected at both ends by sealing portions. A composite container, characterized in that the bag has a protruding portion at a substantially central portion of a seal portion at both side ends and an opening at a substantially central portion of both side ends of the sleeve.

  An eighth invention is the composite container according to any one of claims 1 to 7, wherein the sleeve has a movable bottom plate on a bottom surface.

  The ninth invention is the composite container according to any one of claims 1 to 8, wherein strength maintaining ruled lines are provided on the front surface and the back surface of the sleeve.

  A tenth invention is the composite container according to any one of claims 1 to 9, wherein the bag is a standing pouch.

  An eleventh invention is the composite container according to any one of claims 1 to 10, wherein the base portion of the bag has a resealing mechanism.

  The twelfth invention has a bag body and a cut portion on the front surface and the back surface of the bag and has an opening line, and the bag body has a base portion, a front surface, and a back surface, each having a front mountain portion and a rear mountain portion. In addition, the base portion is covered with the sleeve in a state where the bag is stored in the sleeve, and the front mountain portion, the rear mountain portion, and the cut portion are exposed without being covered by the sleeve. A composite container according to any one of claims 1 to 11.

  According to the present invention, the bag has a protruding portion substantially at the center portion of the seal portion at both side ends, and has an opening at the substantially center portion of both side ends of the sleeve. In this case, it is easy to use the handle. In addition, since the protruding portion is located substantially at the center, it helps to maintain the bag shape. Further, with such a structure, it is easy to cover the bag from the sleeve up to the upper portion of the bag body, and deformation of the bag can be prevented even at the upper portion. In particular, by suppressing the deformation of the bag in a configuration in which the weight is large enough to be poured, it is possible to prevent accidents such as hot water scattered due to the deformation of the bag during the pouring.

  In addition, since it becomes possible to maintain the outer shape as a container for heavy contents only with such a composite container, it can be used even in a disaster where it is difficult to prepare another container.

It is a conceptual front view of a compound container showing a conventional embodiment. It is a conceptual front view of the bag of the composite container which shows a comparative example.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual front view of a composite container showing one embodiment of the present invention. In this embodiment, since the front and back are the same type, only the front view will be described. Note that, for a plane or bottom shape unknown from FIG. 1, FIGS. 7 and 8 are appropriately referred to.

  The composite container includes a bag and a sleeve 101. As shown in FIG. 5, the bag is a four-sided seal bag having a gusset 512 having a gusset fold 513 on the bottom surface and a seal portion 502 on all sides, but may be a three-sided seal bag having one side, for example, an upper side folded back. Absent.

This bag has an opening line. In this embodiment, the bag includes a horizontal opening line 503 and an end oblique opening line 504 in a diagonal straight shape that descends to the end of the bag from the middle of the horizontal opening line 503 to the left and right. With the horizontal opening line 503 and the end oblique opening line 504, the bag body and the primary cut portion 50 are opened.
7 and a secondary cut portion 508.

  In this case, the end diagonal opening line does not need to be 45 degrees, and can be appropriately selected such as 30 degrees or 60 degrees depending on the ease of folding, the condition of maintaining the fixed state, and the strength of the bag material. The optimum changes depending on whether or not easy folding processing such as ruled line processing is performed. Further, the horizontal opening line and the end oblique opening line do not necessarily have to be straight lines.

  The primary cut portion 507 is a substantially rectangular region extending horizontally above the horizontal opening line 503, the secondary cut portion 508 is a substantially triangular region between the horizontal opening line 503 and the end oblique opening line 504, and the bag body is The next cut portion 508 has a rectangular shape lacking both upper ends of a portion below the horizontal opening line 503 and the end oblique opening line 504. In addition, although it can be deformed by the shape of the horizontal opening line and the end oblique opening line, it is necessary that both the front and rear sides project from the upper surface from at least both ends.

  Further, a horizontal opening line notch 505 is provided at both ends of the horizontal opening line 503, and an end diagonal opening line notch 506 is provided at both lower ends of the diagonal opening line 504.

  In this case, the opening line can be cut off from other portions by half-cutting, embossing, or the like. In addition, if the bag does not require a barrier property, it can be configured with perforations. The notch can be V-shaped, U-shaped, I-shaped, or the like, but is not necessarily provided. Further, the end oblique opening line notch 506 can have an angle corresponding to the inclination of the opening line.

  When a virtual line connecting both lower ends of the end diagonal opening line 504 is formed as a folding virtual line 510, a trapezoid surrounded by the horizontal opening line 503, the end diagonal opening line 504, and the folding virtual line 510 in the bag body. The region is referred to as a chevron portion 509, and a substantially rectangular region below the folding virtual line 510 is referred to as a base portion 501.

  As described above, if the chevron is gentle near the end, the opening is easy, but the function of fixing the bag when folded is reduced. On the other hand, if the angled portion is steep at the end, it is difficult to open the bag, but the function of fixing the bag when folded is improved.

  In addition, even if the opening line is formed by opening once so that the horizontal opening line and the end diagonal opening line are connected to each other, a single opening is performed so that the horizontal opening line, the vertical opening line, and the end horizontal opening line are connected. A mountain-shaped portion may be formed by opening.

  It is not necessary to provide an easy folding means for the folding virtual line 510 if the bag has sufficient flexibility, but it is also possible to provide an easy folding process by half cutting, embossing or the like as necessary. In this case, in the case where the easy folding process is provided, it is preferable to provide the easy folding process so that it is easy to fold outward, that is, on the front side on the front side, and on the back side on the back side.

  In the above-described embodiment, the opening line is completely cut. However, since there is a possibility that the cut portion may become garbage, the opening line is stopped halfway on one of the front and back sides so that such a cut portion is not completely separated. Structures are also possible. In particular, since the secondary cut portion is triangular and small, when the content is food such as noodles, there is a high need to prevent the content from being mixed.

  A semicircular projection 514 is provided substantially at the center of the left and right seal portions 502 of the bag, that is, slightly above the base portion 501, and a hole 515 is provided therein. This has the effect of contributing to stabilizing the shape of the bag not only at the top but also at the ends. The shape of the protruding portion can be appropriately selected.

  The shape of the protruding portion is not limited to a semicircular shape, and may be a rectangular shape as shown in FIG. 9 or a shape having a claw portion as shown in FIGS. 10 and 11. It is a preferred shape to round the part.

  In addition, if there is a hole in the protruding portion, it has an effect of making it difficult to slip when held by hand, and it is also useful to hook a rod or something in this hole as needed. Needless to say, as a configuration for preventing such slippage, an embossing or a half cut may be appropriately inserted instead of the hole, or a configuration in which a number of fine holes are provided instead of the hole may be used.

  When the movable bottom plate 1203 of the sleeve 101 described later is folded with the bottom center folding line 1308 down, the bag is lowered by the length from the bottom folding line 1307 to the bottom center folding line 1308. When the composite container is erected, the bag rises by that length, but at this time, if the upper claw 1603 is provided on the protruding portion 1602 as shown in FIG. The shape stability of the bag can be enhanced by being fitted.

  On the other hand, if the lower claw portion 1703 is provided on the protruding portion 1702 as shown in FIG. 11 to prevent the contents from becoming heavy due to the pouring and the bag being deformed downward and the hot water being spilled, as shown in FIG. Even if it is deformed, the projection is not further deformed by being hooked on the lower end of the cutout portion 1302, and at least the deformation of the bag portion below the projection 1702 can be suppressed by the sleeve, and the hot water is spilled. Accidents can be reduced.

  In addition, when the situation of providing such an upper claw portion and the situation of providing a lower claw portion conflict with each other, a configuration in which both the upper claw portion and the lower claw portion are provided in the same protruding portion may be considered. In any of these configurations, a configuration may be added in which embossing or half-cutting is appropriately inserted instead of the above-mentioned hole or hole, or a large number of fine holes are provided instead of this hole.

  Since it is preferable that such a protruding portion has strength, it is preferable that the protruding portion is formed not only with one sheet but also with both sides sealed, and embossed for maintaining strength as necessary. It is often preferable to add strength maintaining means.

  As the material of the bag, as a base material layer, polyethylene, polypropylene, polyethylene terephthalate, polyamide, or a laminate of these synthetic resin layers in a plurality of layers, and a barrier layer formed thereon by vapor deposition aluminum, aluminum foil, silicon oxide vapor deposition, or the like. It is also possible to add those provided, but biaxially stretched polyethylene terephthalate, biaxially stretched polypropylene, biaxially stretched nylon with aluminum oxide deposited thereon, and the like, and further, as a heat adhesive resin layer as a sealant, low density polyethylene , Medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, ethylene-vinyl acetate copolymer, biaxially oriented polypropylene, unoriented polypropylene, ethylene-propylene copolymer, and the like are preferable, and urethane resins and low-density polyethylene are more preferable. Contact Adhesive layer, and other light-shielding layer, the printing layer such as described in the instructions, may be provided with a functional layer such as a surface protective layer.

  A line fastener 511 as a reseal mechanism is provided in parallel above the base portion 501 and below the folding virtual line 510. This is a structure in which the concave material on the front surface and the convex member on the rear surface can be easily fitted, and can be temporarily sealed by pressing from both sides.

  Such a reseal function is used when steaming after pouring or when it is not eaten, but it does not matter if cooking is left open and such a reseal function is not necessary when eating. . Further, the resealing function can be appropriately selected according to the intended use, not only for the wire fastener but also for a simple engagement or a structure using a hook-and-loop fastener.

  A lower portion of the base portion 501 is sealed with a gusset portion 512 in which a gusset fold 513 is formed in advance.

  Of course, the bottom does not need to have a gusset structure, but in order to stably form the bottom when it is heavy, it is preferable to use means such as induction crease processing that forms the bottom naturally.

  The sleeve 101 has a cylindrical shape in which the front surface and the back surface are connected by pasting a margin (not shown) at both ends, but the sleeve 101 can be folded at both sides and crushed into a flat shape. This state is shown in FIG.

  In the crushed state, the sleeve surface 1201 is provided with a cutout portion 1202 in the middle of the folding line at the left and right ends and slightly above the center, and forms a square hole when standing.

  Further, a movable bottom plate 1203 is provided which connects the front surface of the sleeve 1201 and the back surface of the sleeve at the center of the bottom surface. Because of the line 1308, the movable bottom plate 1203 can be broken and crushed into a substantially flat plate shape as shown in FIG.

  The bottom structure has such a structure that the bottom width is variable so that the thickness can be changed to reduce the volume at the time of transportation. However, if the bottom width can be fixed, the bottom member may be formed entirely. Strength can be further increased.

  On the front surface and the back surface of the sleeve, a quarter circle strength maintaining ruled line 1204 is provided as a strength maintaining means from the center of the upper end 1808 of the sleeve toward the left and right ends. This has been subjected to press ruled line processing like other folding lines.

  If the strength is sufficient, such strength maintaining processing as such strength maintaining means is not necessary, and if necessary, the shape such as crease processing may be changed according to the required strength, or a resin for reinforcing strength may be used. It may be reinforced by printing.

  Further, when the sleeve 101 is erected in a boat shape, the movable bottom plate 1203 is opened, and the strength maintaining ruled lines 1204 provided on the front and rear surfaces of the sleeve help to further maintain the erected shape.

  A high-strength material such as a cardboard is preferable as the material of the sleeve. However, when a large-sized material requiring high strength is required, a rigid plastic or a honeycomb structure can be used. If the material is paper quality, if water resistance is required, perform a water-repellent surface treatment such as printing with a resin coat or water-repellent ink as necessary, or laminate a film-attached resin layer on the surface. Although it is also possible to perform printing, it is also possible to simply print the content display and usage method.

  Such a bag is stored in the sleeve 101, but as shown in FIG. 1, the height of the cutout 1008 of the sleeve 101 and the height of the protrusion 514 of the bag are substantially the same, and the cutout 1008 is slightly larger. The protruding portion 514 of the bag can be protruded from the notch 1008, which helps to improve the shape stability of the bag.

  A locking cut 1802 is provided in the center of the upper part of the sleeve 1801 as shown in FIG. 14, a locking hole 1805 is provided in the chevron 1803, and a locking tongue 1905 formed by the locking cut as shown in FIG. The hook portion 1902 is hooked on the locking hole 1903 to securely fix the angled portion 1902 in a folded state, which helps to ensure the shape stability of the bag.

  In this case, there is a disadvantage that the gas barrier property of the bag is lost. However, if a weakening process such as half cutting is used instead of the locking hole, it is possible to have a certain degree of gas barrier performance. Can be selected appropriately depending on the contents.

  If such a bag has a gusset with a four-sided seal, it is sealed three-sided with a gusset piece in a gusset-folded state, and if there is a protrusion, it is appropriately punched at the same time as notch punching. Next, each opening line is weakened by an appropriate means such as laser processing.

  The sleeve is formed by applying a ruled line process to a cardboard or the like in a shape including a margin, performing a punching process, and then bonding with a margin.

  Finally, the bag is fitted into such a gusset to complete the composite container of the present application.

(Example 1)
A four-sided seal bag having a gusset 512 having a gusset fold 513 on the bottom surface and having a seal portion 502 on all sides. It consists of an oblique straight line end diagonal opening line 504 descending at 45 degrees. At both ends of the horizontal opening line 503, a horizontal opening line notch 505 is provided, and at both lower ends of the end oblique opening line 504, V-shaped end oblique opening lines notches 506 are provided.

  A semicircular protrusion 514 formed by a seal is provided substantially at the center of the left and right seal portions 502 of the bag, that is, at a portion slightly above the base portion 501, and at the center of the inside thereof, each half is about half of the protrusion. A circular hole 515 is provided.

  A line fastener 511 is provided slightly below the strength maintaining ruled line 1204 above the base portion 501, and a lower portion is sealed by sandwiching a gusset portion 512 in which a gusset fold 513 is previously formed.

  The sleeve has a front plate and a rear plate that are slightly larger than the bag and are adhered with extra margins, and cutouts that are slightly larger than the protrusions from the folds are provided from the front surface to the back surface at the center of both ends.

  On the other hand, there is provided a movable bottom plate 1203 having an appropriate folding width capable of maintaining strength and connecting the sleeve front surface 1201 and the sleeve back surface to the center of the bottom surface. The movable bottom plate 1203 is connected to the front surface and the back surface by a bottom fold line 1205. ing.

  On the front and rear surfaces of the sleeve, a quarter circle strength maintaining ruled line 1204 is provided from the center of the upper end 1808 of the sleeve to the end of a point slightly above the lower end of the left and right ends.

  When the sleeve 101 is erected in a boat shape, the movable bottom plate 1203 is opened, and when the bag is stored in the sleeve 101, the protruding portion 514 of the bag can be brought out from the notch 1008 as shown in FIG.

  Next, in the composite container as shown in FIG. 1, the primary cut portion 105 is cut off by cutting the horizontal opening line 103 from the horizontal opening line notch 505, and the horizontal opening line 103 becomes a linear primary opening end 203. It looks like 2.

  Next, from the state of FIG. 2, the secondary cut portion 106 is cut off by cutting the horizontal opening line 103 from the left and right end diagonal opening line notch 506, and a mountain portion 303 having a height of 20 mm is formed. Looks like

  Next, the state shown in FIG. 3 is obtained by folding the front mountain-shaped portion 303 on the front surface and the rear mountain-shaped portion 303 on the rear surface from the state shown in FIG.

  In this state, as shown in FIG. 8, hot water 1408 is poured from the bottom to a height of 80%, but the shape is maintained without sagging due to the protruding portion, and the folded shape of the chevron 303 is maintained. We were able to.

  In addition, since the projection 404 has the hole 405, the user can easily move the camera by holding both the projections 404 with both hands.

(Example 2)
Example 1 was the same as Example 1 except that the protruding portion of the bag was not provided with a hole and the upper claw portion 1603 was provided. When this composite container was raised, the upper claw portion 1603 was hooked on the upper end of the notch 1008 and stood up in a stable shape.

(Example 3)
Example 1 was the same as Example 1 except that a hole was not provided in the protruding portion of the bag and a lower claw portion 1703 was provided. In this condition, hot water was poured from the bottom until the height reached 80%. Although the bag is slightly bent, the lower claw portion 1703 is caught by the lower end of the notch portion 1008, whereby the bag is supported by the sleeve so that the bag does not deform any more and maintains a stable shape. Was able to maintain.

(Comparative Example 1)
It was the same as Example 1 except that a bag having no protrusion was used as shown in FIG. Since only the movable bottom plate 1203 defines the positional relationship between the sleeve and the bag, the movable bottom plate 1203 can be moved as much as possible. Therefore, when the chevron 402 is folded, the sleeve 401 cannot be folded with the sleeve 401 interposed therebetween. It was difficult to maintain the open state.

  Also, since the opening state is maintained only by folding the angled portion 402, the angled portion is wrinkled according to the pouring, and the opening state was not removed. Was hesitated for a moment.

  Further, when transporting such a composite container, the entire composite container is heated by hot water, and it is not preferred to transport the composite container until it is cooled.
