When the exterior sheet is provided, an insertion port for the support member 2 is formed in the exterior sheet, or an insertion port is formed between the wall surface sheet and the exterior sheet.

Each sheet constituting the pouch container 10 is usually composed of a resin film. The resin film constituting the sheet is required to have basic performance as a package such as impact resistance, abrasion resistance, and heat resistance. Further, since each of the above sealing portions is usually formed by heat sealing, the sheet is also required to have heat sealing properties. As the sheet, a multi-layer sheet having a base film layer and a sealant layer that imparts heat-sealing properties is suitable, and when high gas barrier properties are required, a gas barrier is provided between the base film layer and the sealant layer. It is preferable to provide a layer.

The base film layer itself may be provided with a gas barrier property. In this case, the barrier layer is used as the base film layer, and the multi-layer sheet has the barrier layer and the sealant layer. Further, when imparting heat-sealing property to both sides of the sheet, a single-layer film for forming a sealant layer described later may be used, and in the case of a multi-layer sheet, whether two layers of the same type or different types of sealant layers are provided. (At this time, one layer of the sealant layer is formally used as the base film layer), or a sheet having the sealant layers on both sides of the base film layer may be used.

Here, the constituent materials of the base film layer, the sealant layer, and the gas barrier layer will be illustrated. Lamination of each of these layers can be performed by a conventional laminating method, for example, dry lamination with an adhesive, thermal lamination in which a heat-adhesive layer is sandwiched and heat-bonded.

The thickness of the base film is, for example, 10 μm to 200 μm, preferably 10 μm to 100 μm.

Examples of the film constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. Can be exemplified by a stretched or unstretched film of. The thickness of the sealant layer is, for example, 20 μm to 200 μm, preferably 30 μm to 180 μm.

The gas barrier layer may be a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin film (for example, a base film layer). ), An example is a film obtained by depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica.

Each sheet may be provided with a printing layer (not shown) for displaying the product name of the contents, the product description such as raw materials and precautions for use, and other various designs. For example, the print layer can be formed on the inner surface of the base film layer by a known method such as gravure printing.

FIG. 2 is a perspective view of the support member 2 which is an example of the embodiment. As illustrated in FIG. 2, the support member 2 has a base portion 3 on which the pouch container 10 is placed and a standing wall portion 4 erected on the base portion 3. The base portion 3 and the standing wall portion 4 are formed of a flat quadrangular panel, and the standing wall portion 4 is formed substantially perpendicular to the upper surface of the base portion 3. The base portion 3 and the standing wall portion 4 are both rectangular in shape, but the base portion 3 is long in the lateral direction and the standing wall portion 4 is long in the vertical direction. The vertical wall portion 4 is formed substantially parallel to the short side of the base portion 3, and the lateral length of the vertical wall portion 4 is shorter than the lateral length of the base portion 3.

In the support member 2, for example, the base portion 3 is placed on a flat surface, and the standing wall portion 4 is inserted into the insertion portion 25 of the pouch container 10. Then, the pouch container 10 is placed on the upper surface of the base 3. The vertical wall portion 4 is preferably formed so that the bottom of the pouch container 10 is in contact with the upper surface of the base portion 3 in a state of being inserted into the insertion portion 25. The vertical wall portion 4 is preferably inserted to the back of the insertion portion 25 (upper side away from the insertion port 27), but for example, the upper and lower portions that do not come into contact with the edge sealing portion 28 formed at the upper end portion of the insertion portion 25, which will be described later. It is said to be the length of the direction.

The vertical length of the vertical wall portion 4 is preferably 30% to 80%, more preferably 50% or more, for example, 50% to 70% with respect to the vertical length of the pouch container 10. The vertical length of the vertical wall portion 4 is preferably 40% to 90%, more preferably 60% or more, with respect to the vertical length of the wall surface sheet (back surface sheet 12) to which the interior sheet 26 is joined. For example, 60% to 80%. The lateral length of the vertical wall portion 4 is preferably 30% to 85%, more preferably 50% or more, for example, 50% with respect to the lateral length of the wall surface sheet (back surface sheet 12) to which the interior sheet 26 is joined. % -80%.

Since the standing wall portion 4 is arranged behind the pouch container 10, it is erected behind the center of the base portion 3 in the front-rear direction. In order to prevent the pouch container 1 with a support member from tipping backward, the standing wall portion 4 is preferably provided at a position away from the rear end of the base portion 3. That is, it is preferable that the base portion 3 extends not only to the front side of the standing wall portion 4 on which the pouch container 10 is placed but also to the rear side of the standing wall portion 4.

The shape of the support member 2 is not limited to the shape illustrated in FIG. For example, the shapes of the base portion 3 and the standing wall portion 4 may be trapezoidal, triangular, semicircular, or the like. Further, a plurality of vertical wall portions 4 may be provided, or the upper portion may be bifurcated (see FIG. 9 or the like described later). The vertical wall portion 4 may have a pole shape (for example, a cylindrical shape, a prismatic shape, etc.) as long as it can be inserted into the insertion portion 25 and can support the pouch container 10.

Hereinafter, with reference to FIGS. 3 and 4, the insertion portion 25 of the pouch container 10 into which the support member 2 is inserted, and related configurations (interior sheet 26, insertion port 27, edge seal portion 28, etc.) To elaborate on.

As shown in FIGS. 3 and 4, the insertion portion 25 is a space provided on the back side of the pouch container 10 into which the standing wall portion 4 of the support member 2 is inserted. The insertion portion 25 is an independent space that does not communicate with the filling space 15, and is provided between the interior sheet 26 and the back surface sheet 12 by joining the interior sheet 26 to the inner surface of the back surface sheet 12. Although the pouch container 10 is self-supporting, a more stable upright state is ensured by the vertical wall portion 4 of the support member 2 being inserted into the insertion portion 25 to support the pouch container 10.

The interior sheet 26 is provided over the entire lateral length of the back sheet 12, that is, over the entire lateral length of the pouch container 10. The lateral length of the interior sheet 26 is not particularly limited as long as the pouch container 10 can be stably supported by the support member 2, but the interior sheet 26 is provided over the entire width of the back surface sheet 12 in consideration of productivity. Is preferable. In this case, the pouch container 10 can be manufactured by an existing bag-making process using a long body such as a wall sheet. In addition, the pouch container 10 can be manufactured by using a general front and back sheet having a sealant layer on one side.

The vertical length of the interior sheet 26 is preferably half or more of the length of the wall surface sheet (back surface sheet 12) on which the insertion portion 25 is provided. A suitable range of vertical length is 50% to 80%. The interior sheet 26 is provided within a range that does not interfere with the bottom gusset sheet 13. In the example shown in FIG. 3, the interior sheet 26 is provided from the vicinity of the upper edge seal portion 17 to the vicinity of the bottom gusset sheet 13.

An edge seal portion 28 is formed on the interior sheet 26 so as to surround a range in which the standing wall portion 4 of the support member 2 is inserted. Then, the insertion portion 25, which is a space isolated from the filling space 15, is formed by the edge sealing portion 28. In the present embodiment, since the interior sheet 26 is provided over the entire length of the back surface sheet 12 in the lateral direction, the interior sheet 26 is joined to the inner surface of the back surface sheet 12 by the side seal portion 19 and the edge seal portion 28. .. In other words, a part of the side seal portion 19 functions as the edge seal portion 28. The edge seal portion 28 is formed in a strip shape over the entire length in the lateral direction at the upper and lower ends of the interior sheet 26.

The peripheral portion of the interior sheet 26 is joined to the inner surface of the back surface sheet 12 by the side seal portion 19 and the edge seal portion 28. On the other hand, the other parts are not joined to the back sheet 12. As a result, the insertion portion 25, which is a space for accommodating the standing wall portion 4 of the support member 2, can be widely formed between the back surface sheet 12 and the interior sheet 26. It is preferable to use a double-sided heat-sealing sheet for the interior sheet 26.

The insertion port 27 is an opening that allows the support member 2 to be inserted into the insertion portion 25, and is formed at a portion of the back surface sheet 12 that overlaps with the interior sheet 26. More specifically, the insertion port 27 is formed in a portion of the back surface sheet 12 that overlaps with the interior sheet 26 and is surrounded by the side seal portion 19 and the edge seal portion 28. The insertion port 27 is formed in a range that does not interfere with each of the seal portions, but is preferably formed at the lower portion of the insertion portion 25 (the lower portion of the back surface sheet 12). In the example shown in FIG. 2, a horizontally long insertion port 27 is formed in the vicinity of the edge seal portion 28 along the seal portion.

The insertion port 27 may be a slit-shaped opening, but is preferably formed by cutting a part of the back surface sheet 12 in order to facilitate insertion of the support member 2. Since the vertical wall portion 4 of the support member 2 is inserted into the insertion portion 25 from the lower side of the pouch container 10, the insertion port 27 is preferably an elongated hole longer in the lateral direction than the vertical wall portion 4. The insertion port 27 is formed, for example, 5% to 10% longer in the lateral direction than the lateral length of the vertical wall portion 4. As described above, since the vertical wall portion 4 is preferably formed with 30% to 85% of the lateral length of the back surface sheet 12, the lateral length of the insertion port 27 is the lateral length of the back surface sheet 12. 35% to 90% of the above is preferable.

The insertion port 27 is preferably formed on the center line α extending in the vertical direction through the center in the lateral direction of the back surface sheet 12, and is particularly preferably formed symmetrically with respect to the center line α. That is, the lateral center of the insertion port 27 is located on the center line α. As a result, the support member 2 can be arranged without being biased to the left or right of the pouch container 10. In the example shown in FIG. 2, the insertion port 27 is formed along the lateral direction of the pouch container 10, but the insertion port 27 may be inclined with respect to the lateral direction and the vertical direction of the pouch container 10.

FIG. 5 is a diagram showing a usage state of the pouch container 1 with a support member. As illustrated in FIG. 5, the pouch container 1 with a support member is used by attaching the dispenser pump 5 to the spout 20 of the pouch container 10. When using the pouch container 1 with the support member, the cap 21 is removed from the spout portion 20 and the dispenser pump 5 is attached to the spout portion 20 instead. That is, the pouch container 10 is used as it is without refilling the contents of the pouch container 10 into another container.

As described above, the pouch container 10 to which the dispenser pump 5 is attached is placed on the base portion 3 of the support member 2 arranged on a flat surface, and the standing wall portion 4 of the support member 2 is inserted into the insertion portion 25. As a result, it is stably supported by the support member 2. According to the pouch container 1 with a support member, a stable use state can be obtained without the pouch container 10 easily tipping over, while having a simple structure and low manufacturing cost. Although the pouch container 10 is self-supporting, it is supported by the support member 2 to ensure a more stable upright state.

The above-described embodiment can be appropriately redesigned as long as the object of the present invention is not impaired. For example, the pouch container may be a standing pouch having only a bottom gusset sheet or a side gusset pouch having a side gusset sheet, and one sheet is used to form the first surface and the second surface. It may be a so-called one-seam pouch. Further, it may be a flat pouch that does not have independence. Even if the pouch container does not have self-supporting property, it can stand upright stably with the spout portion facing vertically upward by the support member.

6 to 10 show another example of the embodiment. In the following, the differences from the above-described embodiment will be mainly described, and the same reference numerals will be used for the same components as those in the above-described embodiment, and duplicate description will be omitted.

The pouch container 10A of the pouch container 1A with a support member shown in FIG. 6 is different from the pouch container 10 in that the interior sheet 26A is joined to the inner surface of the surface sheet 11A and the insertion portion 25A is provided on the surface sheet 11A side. .. Further, in the pouch container 1A with a support member, the support member 2A has a plurality of vertical wall portions 4, and one of them is inserted into the insertion portion 25A. Further, the insertion port 27A formed in the portion of the surface sheet 11A that overlaps with the interior sheet 26A is inclined with respect to the lateral direction and the vertical direction of the pouch container 10A. The insertion port 27A is formed from the vicinity of the edge seal portion 28A formed at the lower end portion of the insertion portion 25A to the vicinity of the edge seal portion 28A formed at the upper end portion of the insertion portion 25A, and is formed from the bottom to the top. It is gradually inclined so as to approach one end in the lateral direction of the pouch container 10A.

The support member 2A has a base portion 3 and vertical wall portions 40, 41, 42 erected on the base portion 3. Each standing wall portion is erected substantially perpendicular to the upper surface of the base portion 3 so as to surround the three sides of the pouch container 10A. In other words, the pouch container 10A is housed in the concave portion surrounded by each vertical wall portion. The vertical wall portion 40 is erected at a position away from the front end of the base portion 3. The vertical wall portion 40 is located on the front side of the pouch container 10A, and a part thereof is inserted into the insertion portion 25A from the insertion port 27A formed in the surface sheet 11A. The standing wall portion 42 is erected at the rear end portion of the base portion 3 and supports the pouch container 10A from the back side. However, the standing wall portion 42 is not inserted into the insertion portion. The standing wall portion 41 is provided substantially perpendicular to the standing wall portions 40 and 42, and connects the respective standing wall portions.

The pouch containers 10B and 10C shown in FIGS. 7 and 8 are joints formed by joining the back surface sheet 12 and the interior sheet 26, and are seals that restrict the lateral movement of the support member in the insertion portion. It differs from the pouch container 10 in that the portions 50 and 51 are provided, respectively.

In the pouch container 10B, seal portions 50 are formed on the left and right sides of the insertion portion 25B. The seal portion 50 is formed in the upper portion of the insertion portion 25B in a vertically long strip shape symmetrically with respect to the center line α. The seal portion 50 is not connected to the edge seal portion 28, but both seal portions may be connected. Each seal portion 50 is preferably formed directly above the left and right end portions of the insertion port 27, and the standing wall portion 4 of the support member 2 is inserted between the seal portions 50.

In the pouch container 10C, one seal portion 51 is formed in the lateral central portion of the insertion portion 25C. The seal portion 51 is formed in the upper portion of the insertion portion 25C in a semicircular shape that is symmetrical downward with respect to the center line α. The seal portion 51 is connected to the edge seal portion 28, and is formed by bulging a part of the edge seal portion 28 downward. That is, it can be said that the seal portion 51 is a part of the edge seal portion 28. In this case, the vertical wall portion 4C of the support member 2C preferably has a recess 52 into which the seal portion 51 can be fitted. The recess 52 is a semicircular recess formed at the upper end of the standing wall portion 4C, and by inserting the standing wall portion 4C so that the seal portion 51 fits into the recess 52, the standing wall portion within the insertion portion 25C is inserted. The lateral movement of 4C is suppressed.

The pouch containers 10D and 10E illustrated in FIGS. 9 and 10 are formed above the insertion port 27 and are provided with openings 60 and 61 for projecting the upper part of the support member from the insertion portion, respectively. Different from. When an exterior sheet (additional sheet) is joined to the outer surface of the wall surface sheet to provide an insertion portion instead of the interior sheet 26, such an opening is formed between the exterior sheet or the wall surface sheet and the exterior sheet. ..

The pouch container 10D has two openings 60 at the top of the insertion portion 25D. Each opening 60 is a horizontally long elongated hole formed symmetrically with respect to the center line α just above the insertion port 27. In the embodiment illustrated in FIG. 9, the upper portion of the vertical wall portion 4D of the support member 2D has a bifurcated shape, and the bifurcated portions protrude from the insertion portion 25D through each opening 60. By projecting the standing wall portion 4D from the opening 60, lateral movement of the standing wall portion 4D within the insertion portion 25D is suppressed, as in the case of the pouch containers 10B and 10C, for example.

The pouch container 10E has one opening 61 at the top of the insertion portion 25E. The opening 61 is a long hole formed in the lateral direction symmetrically with respect to the center line α just above the insertion port 27. In the embodiment illustrated in FIG. 10, the standing wall portion 4E of the support member 2E protrudes from the insertion portion 25E through the opening 61 and is in contact with the spout portion 20. The vertical wall portion 4E abuts on, for example, the flange portion 20b of the spout portion 20 to support the spout portion 20.
