The secondary bag-making product can be formed in-line using a bag-making machine equipped with a device for cutting off the outer portion of the oblique seal portion.

A diagonal seal is applied to the corner of the pouch,
By cutting off the outside of the oblique seal portion, a portion that becomes a dead space when the contents are filled can be reduced. The shape of the oblique seal portion may be a straight line or a curve.

In the pouch of the present invention, a tube film obtained by a method such as inflation may be used, and the side gusset member may be folded by pushing plates from the left and right of the film.

As a film material constituting the pouch of the present invention, for example, a tube-shaped single-layer film manufactured by an inflation film forming method or the like can be used, but a composite film mainly composed of plastic is more preferably used. preferable. The composite film is composed of at least a base material layer and a heat seal layer. Usually, as shown in FIG.
Is an intermediate layer 4 between the base material layer 41 and the heat seal layer 43.
6 (excluding the adhesive layer), four intermediate layers (42 (1) and 42 (2) as shown in FIG. 6B), or a plurality of layers. They may be stacked.

First, since the base layer 41 of the composite film constituting each surface member of the pouch of the present invention is a basic material constituting the pouch, it has excellent properties in mechanical, physical, chemical, etc. For example, a polyester-based, polyamide-based, polypropylene-based, polycarbonate-based, or polyacetal-based resin can be used. Further, as the film using these resins, any of unstretched or stretched film stretched in uniaxial or biaxial directions can be used, and the thickness of the film may be strength, rigidity, etc. as a basic material. Any thickness may be used as long as it can be held to the minimum necessary. If the thickness is too large, heat sealing takes time, productivity is reduced, and costs are increased. If the base material layer is too thin, strength, rigidity, etc. decrease, which is not preferable.

In the present invention, the thickness of the base material layer 41 is suitably about 12 to 30 μm for the above reasons. In addition, the film made of the synthetic resin is a film on which polyvinylidene chloride is applied as necessary or a film on which a vapor-deposited layer of aluminum, silicon oxide, aluminum oxide, indium oxide, tin oxide, zirconium oxide, or the like is formed. A configuration having a barrier property may be employed. In addition, when the base layer is printed, it is usually used as an outer surface layer, and is often printed on the back side (the surface on which the intermediate layer or the heat seal layer is bonded), so that printability is also required. . As the base material layer 41, a stretched film stretched in a uniaxial or biaxial direction is preferably used because of its rigidity and good workability including the printing.

The heat seal layer 43 of the composite film 40 constituting each surface member of the pouch of the present invention may be any material that can be heat-sealed (sealed) when the composite film is made. High-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, ethylene-α-olefin copolymer polymerized using a metallocene catalyst, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, Ionomer resins, ethylene-acrylic acid copolymers, ethylene-methyl acrylate copolymers, resins of one or more resins of ethylene-methacrylic acid copolymers, or sheets made of these can be used. . In particular, the ethylene-α-olefin copolymer polymerized using the metallocene catalyst has a narrow molecular weight distribution and a stable copolymerization ratio, and therefore has excellent low-temperature heat sealability and hot sealability, and gusset. It is a packaging material suitable for preventing poor sealing caused by a step in the film overlapping portion of the upper and lower seals.

The thickness of the heat seal layer 43 is 30
５００500 μm is appropriate. If the thickness of the heat seal layer 43 is less than 30 μm, there is a possibility that the sealing property may be poor, the sealing strength may be insufficient, and the bag may break due to a drop impact or the like. On the other hand, when the thickness of the heat seal layer 43 exceeds 500 μm, it takes a long time to heat seal and the workability is reduced.

An intermediate layer 42 may be provided between the base layer 41 and the heat sealing layer 43 of the composite film used for the pouch of the present invention.
This is provided when the function as a packaging bag cannot be sufficiently achieved with the two-layer configuration of the heat sealing layer 43 and the like. Further, the intermediate layer 42 may be two or more layers as described above. The functions of the intermediate layer 42 include gas barrier properties (gas barrier properties), mechanical toughness, rigidity, bending resistance, piercing resistance, impact resistance, abrasion resistance, cold resistance, chemical resistance, and the like. Yes, these functions required as a packaging bag are often achieved by providing the intermediate layer 42. Examples of the material used as the intermediate layer 42 include metal foils such as aluminum, iron, copper, and tin, or polyolefins such as polyethylene terephthalate, polyamide, polyethylene, and polypropylene, polyvinylidene chloride, polycarbonate, polyvinyl alcohol, and ethylene-propylene. Films of copolymers, ethylene-acrylic acid copolymers, saponified ethylene-vinyl acetate copolymers or films obtained by coating these films with polyvinylidene chloride, or aluminum, silicon oxide, aluminum oxide, indium oxide, oxidized A film on which tin, zirconium oxide, or the like is deposited can be used. Further, as the intermediate layer 42, one or more of these materials can be used in combination.
The thickness of the intermediate layer 42 is only required to satisfy the function required as a packaging bag.
It can be appropriately selected as needed.

The composite film can be obtained by laminating the base material layer 41, the heat seal layer 43, the intermediate layer 42 and the like as required by a known dry lamination, a T-die pressing method or the like. When the T-die extrusion method is used, an anchor coat agent may be applied in advance to a film to be extruded or the like as necessary in order to improve the adhesiveness.

The spout assembly attached to the pouch with spout, which is the primary container in the bag-in-carton of the present invention, has a shape as shown in FIG.
At least an adhesive base 53 thermally fused to the edge of the pouch.
And a tubular portion 54 which is located outside the pouch when attached to the pouch and serves as an outlet for taking out contents. A cap 52 is mounted on the cylindrical portion by screwing or the like. Further, it is desirable that the adhesive base 53 has a shuttle-shaped cross-section so that heat fusion and sealing can be reliably performed when the adhesive base is mounted on the pouch. As shown in FIG. 5C, the spout outlet assembly 50 is mounted on the pouch by opening the unsealed portion 38 provided on the above-mentioned pouch,
Inserting the connecting portion 56 and the blocking prevention rib 57 into the pouch,
It is obtained by applying pressure and heating to the surface of the adhesive base 53 and the inner surface of the unsealed portion of the pouch, and performing thermal fusion.

FIG. 5 shows the outer surface of the cylindrical portion 54.
(B) As shown in FIG.
5. A flange 59 or the like for ensuring the transfer of the pouch with a spout may be provided. Further, as shown in FIG. 5A, the blocking prevention rib 5 is connected to the adhesive base 53 via the connecting portion 56.
7 is desirably provided. Blockage prevention rib 5 in this case
Numeral 7 is a cross section of the shape ∈, which shows not only the function of preventing the pouch from being clogged in the final stage of taking out the contents but also the function as a flow path when sucking the liquid remaining in the back of the pouch. By providing such a blocking prevention rib 57, the contents can be taken out stably to the end.

The resin used for molding the spout body of the spout assembly in the bag-in-carton of the present invention is preferably a resin that can be thermally bonded to the inner surface of the pouch and has good screwing properties with the lid. Are resins such as low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, α-olefin copolymer polymerized using a single-site catalyst, and polypropylene.

The cap constituting the spout combination is formed separately from the spout body and can be obtained by injection molding a thermoplastic resin, for example, polyethylene, polypropylene, polyamide or the like. The spout assembly is inserted with the unsealed portion of the pouch main body opened, is sandwiched by the unsealed portion, and is pressurized and heated from the outside of the pouch, so that the pouch and the adhesive base are thermally fused.

In the bag-in-carton of the present invention,
By attaching the spout combination having the obstruction preventing rib to the pouch with the spout of the primary container, the pouch is not obstructed in taking out the contents, and the obstruction preventing rib also forms the flow path, so that the final It is possible to take out almost no residual liquid. Further, the used bag-in-carton can be separated into a primary container, a pouch with a spout and a carton, so that disposal treatment is easy.

Further, in the carton according to the present invention, in the assembled state, the front wall and the rear wall form a gradient (hereinafter, inversely tapered) in which the front wall and the rear wall are narrowed downward. In such applications, even if the contents stored in the primary container become heavy, the contents can be carried with one hand, and the outer container does not slip off from the hand and is easy to hold. Further, as shown in FIG. 7, the shape of the cartridge receiving portion 60 of the device has a gradient (hereinafter referred to as forward taper) having the same angle as the reverse taper angle of the front wall and the rear wall of the carton of the present invention. This allows the ink cartridge or the like to be stably mounted or mounted when set. Further, the carton of the present invention is lightweight when used as a concentrated fruit juice for a vending machine or as an exterior of an ink cartridge, and can be separated from the primary container for disposal after use, and is environmentally friendly.
