Description

The present invention relates to a side gusset bag with its own contents, a side gusset bag with a spout, a method for manufacturing a side gusset bag with contents, a carton for a side gusset bag with contents, and a carton storage body for a side gusset bag with contents.

A side gusset bag that expands into a rectangular parallelepiped shape when the contents are accommodated, and a side gusset bag with a spout in which the side gusset bag has a spout that serves as a pouring inlet are suitable for liquid beverages, seasoning liquids, jelly-like beverages, etc. It is widely used as a container for storing various contents such as viscous substances such as miso, ice cream, and frozen desserts such as frozen desserts.

In such a side gusset bag, the side gusset part is folded up before filling, and the entire container has a flat shape, so that it can be transported and stored in a small space. Further, when filling the contents, the folded side gusset portion opens to accommodate a large amount of contents. In addition, since it has self-supporting properties, by allowing the side gusset bags containing contents to stand up on their own when displaying them, it is possible to increase the number of items displayed per unit area and efficiently display them. Furthermore, the side gusset bag after the contents have been taken out contributes to reducing the volume of waste by folding the side gusset part again.

When such a content-containing side gusset bag stands on its own, the bottom part is formed by bending the lower parts of a pair of flat parts extending in the height direction at right angles so as to overlap each other when the bag is filled with contents. However, for example, when the contents are in liquid form, the thickness of the packaging material used for the bag must be increased in order to prevent liquid leakage and increase the strength of the bag when it is dropped. Therefore, the bending rigidity of the packaging material in the vicinity of the sealing part of the bottom part increases, making it difficult to bend, and even if the packaging material is bent, the force of trying to return it becomes large. As a result, the elasticity of the packaging material exerts a force on the bottom part to project it downward, and as a result, there is a problem in that the side gusset bag containing the contents tends to fall over. If a side gusset bag containing contents falls over while being displayed, for example, the product name or design printed on the flat surface becomes invisible, reducing the advertising appeal.

For this reason, for example, a side seal part that joins the flat part and the side gusset part and a lower seal part that joins the flat parts at the bottom are joined diagonally to form an inclined seal part. A side gusset bag containing contents is known in which the packaging material is cut on the outside of the bottom part to reduce the force of bending the bottom part to protrude downward, thereby preventing the bag from tipping over during free-standing display. Furthermore, a gusset pouch with a spout is also known in which a pleated self-supporting portion is formed at the position of the planned bottom shape retention line (for example, see Patent Document 1).

JP2008-254788A

[Side gusset bag with spout and contents]
FIG. 1 is a perspective view showing a side gusset bag with spout and contents according to the present invention in a self-supporting state. Moreover, FIG. 2 is a perspective view showing a state in which the spouted side gusset bag with contents according to the present invention is laid down. FIG. 3 is a plan view showing the spouted side gusset bag before being filled with contents.
As shown in FIGS. 1 and 2, the spouted side gusset bag 1 with contents according to the present embodiment includes a side gusset bag 2, a spout 3 liquid-tightly attached to the top of the side gusset bag 2, and a spout 3 attached to the spout 3. A cap 4 is provided. A storage space S is defined inside the side gusset bag 2, and the storage space S is filled with contents M such as a fluid.

As shown in FIG. 3, the side gusset bag 2 before being filled with the contents includes a pair of flat parts 12, 12 forming a pair of exterior sheets facing each other in the front and back, and left and right corresponding sides of the pair of flat parts 12, 12. Side parts 13, 13 forming a pair of left and right gusset sheets arranged between the parts and whose widthwise centers are folded inward along the fold line 13a, and these flat parts 12, 12 and the side parts 13, A cylindrical body 14 whose cross section is substantially square is formed when the contents are stored with the inside sealed by the cylindrical body 13 .

The pair of plane parts 12, 12 are formed of sheet materials that are substantially rectangular packaging materials of the same size, and the upper and lower edges are joined at the heat-sealed part in a mutually overlapping state. . However, since the side parts 13, 13 folded inward are interposed between the left and right sides of the pair of flat parts 12, 12, the upper edges and the lower edges are directly joined to each other. Only the parts excluding the upper and lower edges are included. Hereinafter, the heat-sealed portion at the upper edge of the flat parts 12, 12 will be referred to as an upper seal portion 17, and the heat-sealed portion at the lower edge will be referred to as a lower seal portion 18.

The spout 3 is joined to the side gusset bag 2 by the upper seal part 17 so as to be sandwiched between the upper edges of the flat parts 12 and 12.

In addition, the left and right side surfaces 13, 13 have their respective side edges along the substantially vertical direction overlapped with the side edges of the front and rear planar sections 12, 12, and the side edges of these planar sections 12, 12 are thermally fused. The upper and lower edges are joined at the heat-sealed portion at the portions overlapping the upper and lower edges of the front and rear planar portions 12, 12. The heat-sealed part between the upper side edge of the flat part 12 and the side part 13 is continuous with the upper seal part 17 and is provided in a straight line, but the lower side edge of the flat part 12 and the side part 13 is The thermally fused portion is provided so that the fused portion continues from the lower seal portion 18 and is inclined obliquely upward to the left and right side portions of the plane portion 12. Note that the heat-sealed portions of the lower edges of the sides of the plane portion 12 and the side portion 13 are provided at two locations, front and rear, on either the left or right sides, so that the heat-sealed portions are provided at two locations, front and rear, on each side. A total of four plane parts 12 and four side parts 13 are overlapped.

Hereinafter, the heat-sealed portion between each side edge portion of the side surface portion 13 along the substantially vertical direction and the corresponding side edge portion of the plane portion 12 will be referred to as a side seal portion 19 . Further, a heat-sealed portion between the lower side edge of the side surface portion 13 and the corresponding lower side edge of the flat portion 12 is referred to as an inclined seal portion 16.

In addition, in the side part 13 of this embodiment, the outer edge of the inclined seal part 16, which is the heat-sealed part between the flat part 12 and the lower side edge of the side part 13, is cut obliquely along the outer edge of the inclined seal part 16. has been done.

As described above, the side gusset bag 2 has a pair of flat parts 12, 12, and side parts 13, 13 disposed between the left and right sides of the flat parts 12, 12, an upper seal part 17 and a lower part. The inner region of the cylindrical body 14, which is liquid-tightly joined to the seal portion 18, the side seal portion 19, and the inclined seal portion 16, and surrounded by these, is a storage space filled with contents such as liquid and viscous material. It is said to be S.

As shown in FIGS. 1 and 2, the side gusset bag 2 with contents in which the storage space S of the side gusset bag 2 is filled with the contents M is located near the upper edges of the left and right inclined seal parts 16 of the flat parts 12, 12. The lower portions of the lower seal portion 18 are bent in a direction in which they overlap with each other than the plane portion bending lines P1, P1 formed in the lower seal portion 18, and the lower seal portion By bending 18 in either the front or rear direction, a substantially rectangular bottom portion 21 is formed in which the boundaries of each side seal portion 19 and each inclined seal portion 16 are connected with a straight line. Such a bottom surface portion 21 is naturally formed by the weight of the contents M filled in the storage space S when the spouted side gusset bag 1 with contents is placed in a free standing position in the vertical direction with the spout 3 facing upward. .

In the content-containing side gusset bag 1 with a spout according to the present embodiment, a valley fold line P3 is formed in the center of the bottom part 21 so that the bottom part 21 protrudes toward the accommodation space S side. Two inclined surfaces 21a and 21b are formed on the bottom surface portion 21, respectively, from both side edge portions P4, P4 near the pair of side surfaces 13, 13 upwardly inclined toward the valley fold line P3.

As a result, the spouted side gusset bag 1 with contents comes into contact with a mounting surface such as a display shelf in the vicinity of both side edges P4, P4 of the bottom part 21 in the freestanding state. By forming the bottom part 21 in such a shape, even if the lower seal part 18 and the inclined seal part 16 that constitute the bottom part 21 have high bending rigidity, the force that causes the bottom part 21 to protrude downward can be suppressed. . As a result, the content-filled side gusset bag 1 with a spout comes to stand on its own in contact with the mounting surface near both side edges P4, P4 of the bottom part 21, and the bottom part 21 does not protrude downward. It is possible to suppress the flat parts 12, 12 from falling over in the front-rear direction.

Note that the valley fold line P3 of the bottom surface portion 21 may be a bent region having a predetermined width, and the sloped surfaces 21a and 21b do not necessarily need to be bent at an acute angle. A crease line or the like may be formed in advance on the side gusset bag 2 before being filled with the contents M at the position where the valley fold line P3 is formed.

As the packaging material constituting the plane part 12 and side part 13 of the side gusset bag 2, a sheet material made of a laminate is used. For the outer layer of the sheet material, a film made of synthetic resin such as polyester, polyamide, polypropylene, polycarbonate, or polyacetal can be used. Further, as these films, any of unstretched films and stretched films stretched in one or two axial directions can be used. It should be noted that the thickness of the film is not particularly limited and may be any thickness that can be maintained at the minimum necessary level, and is usually about 12 to 25 μm. Further, since the resin film used as the outer layer may be printed, printing suitability is required, and it is preferable to use a stretched film stretched in a uniaxial direction or a biaxial direction. Furthermore, synthetic paper, cellophane, paper, non-woven fabric, etc. can also be used as appropriate.

On the other hand, examples of the inner layer of the sheet material include low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, ethylene-vinyl acetate copolymer, ionomer resin, ethylene-acrylic acid copolymer, etc. Polymers, resins made of one or more of resins such as ethylene-methyl acrylate copolymer, ethylene-methacrylic acid copolymer, polypropylene, and ethylene-propylene copolymer, or films of these resins can be used. The thickness thereof is not particularly limited and is suitably 30 to 200 μm.

Furthermore, if necessary, an intermediate layer may be provided between the outer layer and the inner layer. The intermediate layer may be a metal foil such as aluminum, iron, copper, or tin, or a film such as polyethylene terephthalate, polyamide, polyvinyl chloride, polycarbonate, polyvinyl alcohol, saponified ethylene-vinyl acetate copolymer, or a polychlorinated film thereof. A film coated with vinylidene, a film coated with an inorganic material such as aluminum, silicon oxide, aluminum oxide, indium oxide, tin oxide, zirconium oxide, or magnesium oxide, or a film made of polyvinylidene chloride can be used. Moreover, one or more of these can be used in combination. The thickness of this intermediate layer only needs to satisfy the functions required for a side gusset bag, such as gas barrier properties, water vapor barrier properties, mechanical toughness, bending resistance, puncture resistance, and impact resistance. , a functional film that can ensure abrasion resistance, cold resistance, heat resistance, and chemical resistance can be appropriately selected as necessary. More specifically, although not particularly limited, a thickness of 6 to 50 μm is appropriate.

In order to ensure gas barrier properties and water vapor barrier properties, a vapor deposition layer may be provided on the outer layer of the sheet material instead of providing a functional film in the intermediate layer as described above.

As the deposited layer, for example, aluminum, silicon oxide, aluminum oxide, indium oxide, tin oxide, zirconium oxide, magnesium oxide, etc. are used.
These laminate films are laminated by a known method such as a dry lamination method or an extrusion lamination method.
Moreover, the plane part 12 and the side part 13 may each be formed from a single layer film.

In particular, in a sheet material in which a metal foil is provided as an intermediate layer of the sheet material, the plastically deformable metal foil suppresses the force of the elastically deformable synthetic resin that tends to bend and return the bottom part 21. The bending rigidity of the inclined seal part 16 is reduced, and the force of bending the bottom part 21 to protrude downward can be suppressed, and the valley fold line P3 and the inclined surfaces 21a, 21b can be stably formed on the bottom part 21. , and it is preferable because it becomes easier to maintain its shape.

[Method of manufacturing side gusset bag with contents]
Next, a method of manufacturing the above-mentioned spouted side gusset bag 1 will be described.
First, when manufacturing the side gusset bag 2, for example, the laminates constituting the pair of side parts 13, 13 are each folded in half along the fold line 13a, and arranged so that the fold lines 13a face each other. There, a pair of flat parts 12, 12 sandwich a pair of side parts 13, 13, and side seal parts 19, 19, a lower seal part 18, and an inclined seal part 16 are formed. Thereafter, in a spout attaching step, the spout 3 is held between the openings at the upper ends of the flat parts 12, 12 to form the upper end seal part 17.

The heat sealing temperature of the lower seal portion 18 and the inclined seal portion 16 is preferably 120° C. or more and 250° C. or less. If the heat sealing temperature is 120° C. or higher, sufficient heat sealing strength and sealing performance are likely to be obtained. On the other hand, if the heat sealing temperature is 250° C. or lower, the seal portion will expand due to the residual heat of the heat seal, resulting in the formation of the lower seal portion 18 and the inclined seal portion 16 that are wider than the intended heat seal width. easy to suppress. This makes it easier to prevent the expansion of the bottom portion 21 from being inhibited when the contents M are filled.
Further, the preferable range of the heat sealing temperature of the side seal portion 19 and the upper seal portion 17 is the same as the preferable range of the heat sealing temperature of the lower seal portion 18 and the inclined seal portion 16.

Thereafter, the laminate is cut obliquely along the outer edge of the inclined seal portion 16, or if the packaging material is made from a wide packaging material, the packaging material is punched out along the overall external shape using a die set or the like. Then, side gusset bag 2 is manufactured.

Next, as a filling process, the contents M are filled into the storage space S of the cylindrical body 14 through the spout 3 of the side gusset bag 2, and then the cap 4 is attached to the spout 3 and the spouted side A gusset bag 1 is formed.

In this filling process, in order to efficiently fill the side gusset bag 2 with the content M from the spout 3 having a small diameter, in order to increase the filling speed, if the content M is distributed at room temperature, the content M is The viscosity of the contents M is reduced by heating the contents M to a temperature higher than room temperature, for example, 80° C. or higher and lower than the deterioration temperature of the contents. The contents to be filled include fluid foods and drinks, such as liquid drinks, jelly, and soup.

In such a filling process, a jig 25 as shown in FIG. 4 is placed at the bottom of the side gusset bag 2. The jig 25 is, for example, a member forming an isosceles triangle. When the contents M are filled into the accommodation space S of the cylindrical body 14, the space between the pair of flat parts 12, 12 expands, and accordingly, the pair of side parts 13, which had been folded along the fold line 13a, 13 spreads.

Then, the lower portions of the flat portions 12, 12 are bent in a direction in which they overlap with each other, thereby forming the bottom portion 21. When the jig 25 is pressed against the bottom part 21, the center part of the bottom part 21 is lifted upward, and a shape that follows the two sides of the isosceles triangle of the jig 25 is given to the bottom part 21. be done. As a result, a valley fold line P3 is formed on the bottom part 21, and two inclined surfaces 21a and 21b are formed that are inclined upward from both side edges P4 and P4 of the bottom part 21 toward the valley fold line P3, respectively. be done.

The shaping of the bottom part 21 using the jig 25 is achieved by filling the contents M at a temperature higher than room temperature, so that the laminate forming the flat parts 12, 12 and the side parts 13, 13 is thermally softened. This can be easily done by doing this.

Thereafter, as a cooling step, the spouted side gusset bag 1 with contents is cooled down to room temperature or lower, for example, 40° C. or lower, with the jig 25 in contact with the bottom surface 21. Through such a cooling process, the bottom surface portion 21 is shaped and fixed into a shape that follows the jig 25, that is, a shape in which inclined surfaces 21a and 21b are formed on the left and right sides of the valley fold line P3.
Through the above steps, the spouted and content-filled side gusset bag 1 of this embodiment is manufactured.

Note that the shape of the jig for forming the valley fold line P3 and the inclined surfaces 21a and 21b on the bottom part 21 may be other than the above-mentioned isosceles triangle, and may also have a shape that lifts the center part of the bottom part 21 upward. For example, the shape may be as follows. For example, it may be a rod-shaped member that comes into contact with the center portion of the bottom portion 21.

In addition, the filling process is performed before the spout attaching process, that is, the spout 3 is held between the openings at the upper ends of the flat parts 12, 12, and the contents M are filled into the side gusset bag 2 before the upper end seal part 17 is formed. After that, a spouting step may be performed.

In addition, in the case of frozen desserts whose content M is chilled and distributed in a frozen state, as long as the content M maintains its fluidity, the fluidity may be reduced after filling at 0°C or lower, for example, around -5°C. By bringing the jig 25 into contact with the bottom part 21 during the cooling process to the extent that it disappears, the bottom part 21 has a shape that follows the jig 25, that is, inclined surfaces 21a and 21b are formed on the left and right sides of the valley fold line P3. The shape is shaped and fixed. In this way, when the content M is a frozen dessert, the laminate is not thermally softened, but the fluidity is lost to the extent that the content M solidifies, thereby changing the shape of the shaped bottom part 21. is fixed by the solidification of the contents M, and there is no possibility that its shape will return to the state before shaping as time passes. Conversely, when the contents M solidify, it is impossible to make the side gusset bag 1 self-supporting unless the shape of the side gusset bag 1 containing the contents is fixed according to the present invention before the contents M solidifies.

[Carton for side gusset bags with contents, carton storage body for side gusset bags with contents]
FIG. 5 is a perspective view showing a carton storage body for side gusset bags with contents, in which a side gusset bag with contents and a spout is housed in a carton for side gusset bags with contents.
A carton storage body (hereinafter referred to as a carton storage body) 30 for a side gusset bag with contents includes a plurality of side gussets with a plurality of spouts, for example, six, in a carton (hereinafter referred to as a carton) 31 for side gusset bags with contents. This is a bag containing bag 1.

This carton 31 is a rectangular parallelepiped box, and has an isosceles triangular cross section with a bottom surface 31a protruding toward the center. When the spouted side gusset bag 1 with contents is placed in the carton 31, the bottom part 21 comes into contact with the bottom face 31a of the carton 31, and due to the weight of the contents M, the bottom part 21 is folded as shown in FIG. A line P3 and two sloped surfaces 21a and 21b that slope upward toward the valley fold line P3 are formed. In particular, after the side gusset bag 1 with contents is stored in the carton 31, by adjusting the atmosphere so that the ambient temperature is lower than before storage, the valley fold line P3 and the sloped surfaces 21a, 21b are more reliably aligned with the bottom surface 31a. It is formed by being shaped by.

The carton 31 may be made of, for example, a member made by folding paper such as cardboard, a member made by vacuum forming a synthetic resin sheet, or the like.

In this way, depending on the shape of the bottom surface 31a of the carton 31, the bottom surface portion 21 of the content-filled side gusset bag 1 with a spout has a valley fold line P3 and two inclined surfaces 21a that are inclined upward toward the valley fold line P3. 21b, the spouted side gusset bags 1 are stored in close contact with each other, so that the flat parts 12, 12 are prevented from expanding in the front-rear direction near the end of the valley fold line P3. Ru.

As a result, compared to the content-containing side gusset bag 1 with a spout in which a valley fold line P3 is formed in advance, the vicinity of the end of the valley fold line P3 may rub against the inner surface of the carton due to vibration during transportation, or the adjacent side gusset bag It is possible to prevent pinholes from occurring due to friction such as rubbing against 1. Furthermore, if this carton 31 is provided with a tear line C or the like so that the upper part can be separated from the lower part, it can be used as is for display at a store, and this also contributes to preventing the spouted side gusset bag 1 with contents from falling over. do.

In each of the above embodiments, a side gusset bag containing a spout and a spout has been described, but the present invention can be similarly applied to a side gusset bag containing a content that does not have a spout.

Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included within the scope and gist of the invention as well as within the scope of the invention described in the claims and its equivalents.

For example, in the embodiment described above, the valley fold line P3 and the two inclined surfaces 21a and 21b may be provided in directions different by 90 degrees when viewed from the bottom side. The two sloped surfaces may extend in parallel to the flat surface in a direction connecting the pair of side surfaces, and the two sloped surfaces may be sloped surfaces extending from the flat surface bending line P1 toward the valley fold line. Furthermore, the valley fold line is a valley fold line whose length is close to a dot shape, and the slope is a slope facing the valley fold line from the both side edges P4, P4 and the flat part bending lines P1, P1. It's okay.
