FIG. 1 is a front view of the pouch 10 which is an example of the embodiment, and also shows an AA line cross section. FIG. 1 shows a state in which the pouch 10 is folded flat and the top sheet 14 is bent toward the front sheet 11. 2 and 3 are views showing a pouch 10 filled with contents.

As illustrated in FIGS. 1 to 3, the pouch 10 is a refill container having a pouch main body 40 including a filling portion 15 of the contents and a spout portion for taking out the contents from the filling portion 15. is there. The pouch 10 is a flexible packaging material container formed by laminating resin sheets, and includes a spout 20 as a spout portion. In addition, instead of the spout 20, the joint portion of the resin sheet may be formed in a flow path shape to serve as a spout portion.

The pouch body 40 includes a front sheet 11 and a rear sheet 12 as wall sheets forming a front surface portion (first surface portion) and a rear surface portion (second surface portion) facing each other. Further, the pouch body 40 includes a bottom gusset sheet 13 forming a bottom gusset portion and a top surface sheet 14 forming a top surface portion. By laminating these sheets, a filling portion 15 which is a closed container space is formed. The pouch 10 is a standing pouch in which the bottom gusset sheet 13 is expanded by filling the contents and the independence is exhibited. In the pouch 10, the spout 20 is attached to the top sheet 14.

As will be described in detail later, the pouch body 40 is connected to the front sheet 11 and the rear sheet 12 in series, and includes a pair of gripping portions 30 for sandwiching and holding the dedicated container 100. As shown in FIGS. 2 and 3, the pair of gripping portions 30 are provided in the vicinity of the spout 20 and on one side of the front seat 11 and the rear seat 12 in the width direction with respect to the spout 20. It is composed of pieces 31A and 31B. By using the pair of gripping portions 30, it is possible to prevent the contents from spilling when the contents are refilled into the dedicated container 100.

The front sheet 11 and the rear sheet 12 are formed long in the vertical direction. The front sheet 11 and the rear sheet 12 may have different shapes from each other, but in the present embodiment, they have the same shape and the same dimensions. The pouch 10 has a long shape in the vertical direction corresponding to the shapes of the front sheet 11 and the rear sheet 12.

Side seal portions 16 are formed on both sides of the front sheet 11 and the rear sheet 12 in the width direction in which the end portions facing each other are joined to each other. The side seal portion 16 is formed, for example, with a constant width along the vertical direction. Each seal portion including the side seal portion 16 may be formed by using an adhesive, but is preferably formed by heat sealing.

The bottom gusset sheet 13 is provided between the front sheet 11 and the rear sheet 12, and is joined to the inner surface of each sheet to form a bottom gusset portion. The bottom gusset sheet 13 is inserted between the front sheet 11 and the rear sheet 12 in a folded state, and the peripheral edge portion thereof is deployably joined to the lower end portions of the front sheet 11 and the rear sheet 12. At the lower end of the pouch 10, a substantially boat-shaped bottom seal portion 17 for joining the front sheet 11 and the bottom gusset sheet 13 and the rear sheet 12 and the bottom gusset sheet 13 is formed.

At the lower end of the pouch 10, a non-seal portion 13a surrounded by a bottom seal portion 17 exists on both sides in the width direction, and a substantially semicircular notch 19 is formed in the non-seal portion 13a. The notch 19 is formed by cutting a part of the bottom gusset sheet 13. The front sheet 11 and the rear sheet 12 are directly joined via the notch 19.

The top sheet 14 is provided between the front sheet 11 and the rear sheet 12, and is joined to the inner surface of each sheet to form the top sheet portion. The top sheet 14 is inserted between the front sheet 11 and the rear sheet 12, and the peripheral edge thereof is joined to the upper ends of the front sheet 11 and the rear sheet 12. At the upper end of the pouch 10, a top seal portion 18 for joining the front sheet 11 and the top sheet 14 and the rear sheet 12 and the top sheet 14 is formed. The top sheet 14 has a through hole for attaching the spout 20. The spout 20 is joined to the inner surface of the top sheet 14, for example, at the periphery of the through hole.

Each sheet constituting the pouch 10 is usually composed of a resin film. The resin film 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, each sheet is also required to have heat sealing properties. Each sheet is preferably a multi-layer sheet having a base film layer and a sealant layer that imparts heat sealability, 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 sealability to both sides of the sheet, a single-layer film forming a sealant layer 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 will be formally used as the base film layer), or a sheet having 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.

Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( (PP), etc.), Polyethylene (Nylon-6, Nylon-66, etc.), Polyacrylonitrile (PAN), Polyethylene (PI), Polyvinyl Chloride (PVC), Polybutylene Chloride (PVDC), Polymethylmethacrylate (PMMA), and An example is a stretched or unstretched film having one or more layers composed of polyether sterephon (PES) or the like. 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.

The front sheet 11 and the rear sheet 12 are generally formed 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. Will be done. The print layer is formed on the inner surface of the base film layer by a known method such as gravure printing. The print layer may be further formed on the bottom gusset sheet 13 and the top sheet 14. Since the pair of extension pieces 31A and 31B extend in the direction in which the spout 20 protrudes from the upper portion of the pouch 10, the print area is expanded without hiding the prints formed on the front sheet 11 and the rear sheet 12. be able to.

In the pouch 10, the top seal portion 18 forms substantially the same plane along the non-seal portion 14a of the top sheet 14 in the folded state shown in FIG. 1, but when the filling portion 15 swells due to filling of the contents, As shown in FIG. 2, the top seal portion 18 stands up along the vertical direction. At this time, since the non-sealed portion 14a that is not joined to the wall surface sheet is in a state along the front-rear direction of the pouch 10, the top-sealed portion 18 is substantially perpendicular to the non-sealed portion 14a. The top seal portion 18 bends upward at a boundary position with the non-seal portion 14a in a state where the filling portion 15 is filled with the contents (filled state of the contents), and stands up at the peripheral edge of the non-seal portion 14a.

It is preferable that the spout 20 is biased to one side in the width direction of the pouch body 40 (front sheet 11 and rear sheet 12) in the top gusset sheet 14. The spout 20 may be attached to the center of the pouch body 40 in the width direction, but by unevenly distributing the spout 20 on one side in the width direction, the angle at which the pouch 10 is tilted when refilling the contents can be reduced. This makes it easier to refill using the grip portion 30. The spout 20 may be provided so that the entire spout 20 is located on one side in the width direction of the pouch body 40 with respect to the center α in the width direction.

The spout 20 is composed of a spout 21 and a cap 22 attached to the spout 21. The spout 21 has a tubular portion 21a that communicates the inside and outside of the pouch body 40, and a flange portion 21b that projects outward in the radial direction of the tubular portion 21a. The spout 21 is attached to the top gusset sheet 14 by heat-sealing the flange portion 21b to the peripheral edge of the through hole, for example, with the cylinder portion 21a inserted into the through hole of the top gusset sheet 14. The cap 22 is, for example, a screw cap screwed into the spout 21.

The front sheet 11, the rear sheet 12, and the top sheet 14 constituting the pouch 10 have a shape on one side in the width direction in which the spout 20 is provided and on the other side in the width direction, sandwiching the center α in the width direction of the pouch 10. Is different. A pair of extension pieces 31A and 31B forming a pair of gripping portions 30 are formed on one side of the pouch 10 in the width direction with respect to the center α in the width direction. In the present embodiment, the extension piece 31A is composed of the front sheet 11 and the top sheet 14, and the extension piece 31B is composed of the rear sheet 12 and the top sheet 14.

The extension pieces 31A and 31B may be composed of only the top sheet 14 or only the wall surface sheet, but preferably are composed of both the wall surface sheet and the top gusset sheet 14. Further, it is preferable that the extension pieces 31A and 31B are composed of a top seal portion 18 in which the wall surface sheet and the top surface sheet 14 are joined. In this case, the rigidity of the extension pieces 31A and 31B is increased so that the extension pieces 31A and 31B can easily stand up when the contents are filled, and the gripability of the dedicated container 100 is improved. The pair of extension pieces may be formed by joining another sheet to the wall surface sheet (see FIG. 10 described later).

The front sheet 11 and the rear sheet 12 constituting the wall surface of the pouch 10 and the extension pieces 31A and 31B have a substantially rectangular shape in the front view that is long in the vertical direction, but the upper end thereof is in a filled state of the contents. It is inclined diagonally upward from the center α in the width direction toward one end in the width direction. Further, the upper ends of the front sheet 11 and the rear sheet 12 are formed along the width direction from the center α in the width direction toward the other end in the width direction, and are inclined diagonally downward at the other end in the width direction and its vicinity. ing.

The top sheet 14 constituting the top surface portion of the pouch 10 and the extension pieces 31A and 31B is formed long in the width direction of the pouch 10. Since the peripheral ends of the top sheet 14 are joined along the upper ends of the front sheet 11 and the rear sheet 12, they have a shape corresponding to the shapes of the upper ends of the front sheet 11 and the rear sheet 12. The top sheet 14 is formed so that the width becomes wider as it approaches one end in the longitudinal direction from the center in the longitudinal direction, and the width becomes narrower as it approaches the other end in the other end in the longitudinal direction.

The front sheet 11, the rear sheet 12, and the top sheet 14 have a portion located on one side in the width direction with respect to the center α in the width direction and a portion located on the other side in the width direction when the pouch 10 is folded. It has overhanging portions 33A and 33B extending in the vertical direction when viewed from the front. The overhanging portions 33A and 33B extend in the vertical direction beyond the virtual line β extending in the width direction along the end of the portion of each sheet located on the other side in the width direction. The overhanging portions 33A and 33B extend in the direction in which the spout 20 protrudes in the filled state of the contents, and form a part of the extending pieces 31A and 31B, respectively.

The top seal portion 18 which is the joint portion between the front sheet 11 and the top sheet 14 and the rear sheet 12 and the top sheet 14 is substantially constant along the edge of the top gusset sheet 14 on the other side in the width direction of the pouch 10. It is formed in width. On the other hand, on one side of the pouch 10 on which the spout 20 is provided in the width direction, the top seal portion 18 is formed wider than the other side in the width direction.

The pair of extension pieces 31A and 31B are preferably formed by a wide top seal portion 18 formed on one side in the width direction of the pouch 10. Hereinafter, the wide portion of the top seal portion 18 constituting the extension pieces 31A and 31B may be referred to as a “widening seal portion 18”.

The widening seal portion 18 constituting the extending pieces 31A and 31B is formed so as to greatly project inside the top surface sheet 14. Therefore, the unsealed portion 14a of the top sheet 14 is narrower on one side than the other side in the width direction of the pouch 10. The top seal portion 18 projects larger toward the inside of the top sheet 14 as it approaches one end in the width direction from the center α in the width direction of the pouch 10, and thus the width gradually increases as it approaches one end in the width direction.

As described above, the top seal portion 18 bends upward at the boundary position with the non-seal portion 14a in the filled state of the contents, and stands up substantially perpendicular to the non-seal portion 14a. In particular, the widening seal portion 18 constituting the extension pieces 31A and 31B has a long length from the inner end to the outer end, which is the boundary position of the non-seal portion 14a, and therefore extends greatly upward. That is, the widening seal portion 18 greatly extends upward from the upper surface (the surface facing upward) of the non-seal portion 14a, and the degree of extension does not constitute the extension pieces 31A and 31B of the top seal portion 18. It is larger than the part. In other words, since the widening seal portion 18 greatly extends upward from the upper surface of the non-seal portion 14a, it functions as a grip portion 30 that sandwiches and holds the special container 100.

In the present embodiment, the height of the non-seal portion 14a in the filled state of the contents is the lowest at both ends in the width direction of the pouch 10, and the inner end of the top seal portion 18 is formed along the width direction of the pouch 10. It is highest in the portion, that is, on the other side in the width direction than the portion to which the spout 20 is joined. The one-sided portion in the width direction of the unsealed portion 14a to which the spout 20 is joined is inclined so that the height becomes lower as it approaches one end in the width direction. The tip of the spout 20 is tilted from vertically above to one side in the width direction of the pouch 10 in the filled state of the contents, and protrudes diagonally upward to the right in front view.

The extension pieces 31A and 31B are provided with the spout 20 interposed therebetween. As illustrated in FIGS. 2 and 3, the extension pieces 31A and 31B have the spout 20 sandwiching the spout 20 from both the front and rear sides of the front sheet 11 side and the rear sheet 12 side in the filled state of the contents. It extends in the direction of protrusion. Since the spout 20 projects diagonally upward to the right in front view, the extension pieces 31A and 31B also extend diagonally upward to the right from the peripheral edge of the unsealed portion 14a. The extension pieces 31A and 31B preferably have the same shape and the same dimensions from each other from the viewpoint of productivity, gripability of the dedicated container 100, and the like. In the present embodiment, the widening seal portion 18 for joining the front surface sheet 11 and the top surface sheet 14 and the widening seal portion 18 for joining the rear surface sheet 12 and the top surface sheet 14 have the same shape and the same dimensions. ..

Further, the extension pieces 31A and 31B (widening seal portion 18) do not extend in the width direction beyond one end in the width direction of the wall surface sheet along the vertical direction of the pouch body 40 at the upper end portion of the pouch body 40. Is preferable. Since the pouch body 40 is manufactured using a long wall sheet that is long in the width direction, the wall sheet can be used efficiently by forming the extension pieces 31A and 31B so that they do not extend in the width direction. Material costs can be reduced.

The extension pieces 31A and 31B (widening seal portion 18) are formed to have a length that can be held by sandwiching the special container 100 between them. Specifically, the extension pieces 31A and 31B abut on the side surface 102a of the container body 102 in a state where the tip of the spout 21 and the edge of the filling port 101 of the dedicated container 100 (the tip of the neck 103) are in contact with each other. Formed as long as possible. Since the pouch 10 has a top sheet 14 along the front-rear direction when the contents are filled, the extension pieces 31A and 31B stand up at intervals in the front-rear direction. Therefore, it is easy to insert the special container 100 between the extension pieces 31A and 31B.

The extension pieces 31A and 31B are formed so as to cover about half of the base side portion of the spout 20 when viewed from the front in the filled state of the contents. On the other hand, the tip of the spout 20 projects upward from the extension pieces 31A and 31B. The extension pieces 31A and 31B extend more in the direction in which the spout 20 protrudes on one side in the width direction of the pouch 10 than in the position where the extension pieces 31A and 31B overlap the spout 20 in the front-rear direction. Since the special container 100 is inserted between the extension pieces 31A and 31B from one side in the width direction of the pouch 10, the extension pieces 31A and 31B are more pouches than the spout 20 as shown in FIGS. 2 and 3. It is preferable to extend a large amount on one side in the width direction of 10.

In the present embodiment, the widening seal portion 18 constituting the extending pieces 31A and 31B is formed so that the width gradually increases as it approaches one end in the width direction of the pouch 10, so that the extending piece 31A stands up upward. , 31B gradually increases as it approaches one end in the width direction of the pouch 10. Since the widening seal portion 18 is formed from a position overlapping the spout 20 in the front-rear direction to one end in the width direction of the pouch 10, it is easy to stand up when filling the contents, and good grip of the dedicated container 100 can be obtained.

Further, the extension pieces 31A and 31B preferably have through holes 32A and 32B. The through holes 32A and 32B are formed in a size capable of exposing, for example, the pad of the finger holding the special container 100. The dedicated container 100 is gripped with one hand via the gripping portions 30 (extending pieces 31A and 31B), but the pad of the finger that grips the dedicated container 100 through the through holes 32A and 32B comes into contact with the dedicated container 100. , The special container 100 is less likely to slip off, and the gripability is improved. The through holes 32A and 32B are formed so as to penetrate the widening seal portion 18, and are surrounded by the seal portion.

The through holes 32A and 32B need only be formed so that the pad of the finger protrudes from the outside to the inside of the extension pieces 31A and 31B through the holes, and must be large enough to allow the finger to be inserted. Absent. It is easier to handle the extension pieces 31A and 31B and the gripability of the special container 100 is improved by making the holes so that the fingers cannot pass through. The shapes of the through holes 32A and 32B are not particularly limited, but a preferable example is a perfect circular shape.

In the front view of the pouch 10, the distance from the tip of the spout 21 of the spout 20 to the through holes 32A and 32B is preferably equal to or longer than the axial length of the neck 103 of the dedicated container 100. In this case, the side surface 102a of the container body 102 can be pressed with a finger while the tip of the spout 21 and the tip of the neck 103 are in contact with each other, and the gripability of the dedicated container 100 is improved.

In the present embodiment, through holes 32A and 32B are formed below the tip of the spout 20 on one side of the pouch 10 in the width direction of the spout 20. The upper ends of the extension pieces 31A and 31B are the highest at one end in the width direction of the pouch 10, but the position is lower than the upper end of the spout 20. The through holes 32A and 32B are the upper end portions of the extension pieces 31A and 31B, and are formed in the overhanging portions 33A and 33B, respectively.

FIG. 4 is an enlarged view showing the vicinity of the spout 20 and the grip portion 30 of the pouch 10, and shows a state in which the cap 22 is removed from the spout 21. In FIG. 4, the point located at the base of the spout 21 (the intersection of the spout 21 and the top sheet 14 (non-sealed portion 14a) and located at the center of the spout 21 in the radial direction) is P1 in the front view. The point located at the center of the spout 21 in the radial direction is referred to as P2, and the point located at the center of the through holes 32A and 32B is referred to as P3.

As illustrated in FIG. 4, the through holes 32A and 32B are formed at positions where the distance from P1 to P2 and the distance from P1 to P3 are substantially the same. In the present embodiment, the length of the straight line L1 connecting P1 and P2 and the length of the straight line L2 connecting P1 and P3 are substantially the same, and are formed by the straight line L1, the straight line L2, and the straight line L3 connecting P2 and P3. The spout 21 and the through holes 32A and 32B are arranged so that the triangle to be formed becomes a substantially isosceles triangle. The lengths of the straight lines L1 and L2 may be different, but in that case, it is preferable that the straight line L1 <the straight line L2. In particular, in the case of a pouch having no top surface gusset like the pouch 10Y shown in FIG. 8 to be described later, the distance to the gripping position of the dedicated container 100 becomes long, so that L2 inevitably becomes long. The angle θ formed by the straight line L1 and the straight line L2 is preferably an acute angle, for example, 10 ° to 70 °, preferably 20 ° to 45 °.

The extension pieces 31A and 31B may have a non-slip portion instead of the through holes 32A and 32B. The non-slip portion is made of a material having a larger coefficient of friction than the sheets constituting the extension pieces 31A and 31B (top sheet 14 facing the dedicated container 100 side), for example, a sheet having a surface roughness larger than that of the top sheet 14. Consists of. The non-slip portion can be formed in the extension pieces 31A and 31B at the same position as in the case of the through holes 32A and 32B, and is formed at a position where it comes into contact with the special container 100.

Here, with reference to FIGS. 5 and 6, a method of refilling the contents from the pouch 10 into the dedicated container 100 by using the grip portion 30 composed of the pair of extension pieces 31A and 31B will be described. As described above, the dedicated container 100 has a container body 102 having a substantially cylindrical shape, and a neck portion 103 protruding from one end in the axial direction of the container body 102 and having a diameter smaller than that of the container body 102, and a filling port 101 is provided in the neck portion 103. It is a formed resin bottle.

As illustrated in FIGS. 5 and 6, when the contents are refilled from the pouch 10 into the dedicated container 100, the dedicated container 100 is placed through the grip portion 30 of the pouch 10 from which the cap 22 (see FIG. 1 and the like) has been removed.

The dedicated container 100 is inserted between the pair of extension pieces 31A and 31B constituting the grip portion 30 from one side in the width direction of the pouch 10 and sandwiched from both front and rear sides. Specifically, the container body 102 of the dedicated container 100 is sandwiched between the upper ends of the extension pieces 31A and 31B in which the through holes 32A and 32B are formed. At this time, the belly of the right hand finger (for example, the thumb and the index finger) protruding toward the container body 102 through the through holes 32A and 32B abuts on the side surface 102a of the container body 102, and the special container 100 is firmly gripped.

Then, with the tip of the spout 21 in contact with the edge of the filling port 101 of the dedicated container 100, that is, the tip of the neck 103, the pouch 10 is slowly tilted so that the tip of the spout 21 faces vertically downward. The contents of the pouch 10 can be transferred to the special container 100. The pouch 10 is lifted by the left hand so as to rotate about the through holes 32A and 32B pressed by the thumb and index finger of the right hand, that is, as a fulcrum of the pouch 10 and the special container 100.

By rotating the pouch 10 around the through holes 32A and 32B in this way, the contents can be refilled while keeping the distance between the spout 21 and the filling port 101 constant, and the contents can be prevented from spilling. .. Further, since the front and rear surfaces can be gripped from the other side in the width direction of the pouch 10, it is easy for women and children with small hands to grip it, and the refilling work of the contents becomes easy.

The above-described embodiment can be appropriately redesigned as long as the object of the present invention is not impaired. For example, as in the pouch 10X shown in FIG. 7, in the filled state of the contents, the grip portion 50 is formed by the pair of extending pieces 51A and 51B provided only on one side in the width direction of the pouch body 54 with respect to the spout 20.
