Hereinafter, the present invention will be described with reference to Figs. 1 to 5 according to a specific embodiment 1 of the invention.

As shown in FIGS. 1 to 3, the gusset container 100 of the first embodiment has a pair of wrapping film 110 and a pair of gusset film 120, and is formed in a bag shape having a rectangular front view and a rectangular shape. A pair of wrapping films 110 are used to form the surface 101 and the inside of the gusset container 100 (not shown). In the side edge portion 111 of the packaging film 110, the upper side edge portion 111a (i.e., a portion covering the upper end of the package film 110 to a predetermined length) is sealed to each other by heat sealing or the like. The length of the upper side edge portion 111a is arbitrary, and is preferably determined by the overall size of the gusset container 100 and the step of filling the contents (described later) by sandwiching the size of the holder of the gusset container 100, for example, about 40 to 50 mm.

Further, in the side edge portion 111 of the packaging film 110, the lower side edge portion 111b (that is, a portion from the lower end of the upper side edge portion 111a to the lower end of the side edge portion 111 in the side edge portion 111 of the packaging film 110) The side edge portions 121 corresponding to the gusset film 120 are sealed to each other in a heat seal manner. The side surface 102 formed by the pair of gusset films 120 has a widened portion 122 and an equal width portion 123. The widened portion 122 has a shape in which the side edge portion 121a extends downward from the upper end portion (the apex portion) (see FIG. 3(b)).

Further, the equal width portion 123 is continuous with the widened portion 122 below the widened portion 122. The equal width portion 123 is almost in the same state as the side edge portion 121b on both sides in the shape structure (see FIG. 3(b)). The width portion 123 The side edge portion 121 of the gusset container 100 (that is, the side edge portion 121a of the widened portion 122 and the side edge portion 121b of the equal width portion 123) is in a state of being packaged on the lower side edge portion 111b of the packaging film 110. A part of the lower portion of the equal width portion 123 is folded inward. Therefore, the folded-in portion constitutes the bottom surface portion 124 of the gusset container 100 (details will be described later). After filling the contents in the gusset container, the upper edge portion 112 (described later) of the gusset container 100 is sealed.

Further, when the side edge portion 121 of the gusset film 120 is packaged to the lower side edge portion 111b of the packaging film 110, the package film 110 assembly is directly packaged with the central portion 111e of the lower edge portion while being in the portion of the direct package It is preferable that the substantially central position is formed as a semicircular notch portion 125 (see FIGS. 4 and 5). Thereby, the gusset film 120 is easily folded inward (details will be described later). The size of each portion of the gusset container 100 is arbitrary.

Further, the constituent materials of the packaging film 110 and the gusset film 120 are not arbitrary, but materials for soft can packaging may be used.

Hereinafter, a method of manufacturing the gusset container 100 will be described with reference to FIGS. 4 and 5. First, the bag body 130 for the gusset container 100 shown below is produced. First, the pair of gusset film films 120 are bent outward (even if the fold lines are directed inward), and a pair of wrapping films 110 are inserted (see FIGS. 4(a) and 4(b)). At this time, the gusset film 120 is mounted in an inclined state in which the lower sides are close to each other, and a part of the upper side to the lower side protrudes from the packaging film 110. Even if the gusset film 120 is in the side edge portion 111 of the packaging film 110, the portion (side edge portion 111c) formed by the upper side edge portion 111a and the both end portions 111d and the center portion 111e of the lower edge portion do not The packaging film 110 is in contact.

The packaging of the packaging film 110 and the gusset film 120 is performed below (see Fig. 4(b)). This encapsulation step encloses the portion where the 111 components overlap, that is, the side edge portion 111c, on the side edge portion of the packaging film 110. Further, the outer edge portion 111f of the continuously overlapping portion is encapsulated in a portion where the wrapping film 110 and the gusset film 120 overlap. Further, in the first embodiment, while the package is being carried out, the package film 110 assembly is also packaged at the central portion 111e of the lower edge portion. Thereafter, in the gusset film 120 and the packaging film 110, the portions projecting from the side edge portions 111c, 111f are cut away to complete the shape of the bag body 130 (see Fig. 4(c)). As shown in FIG. 4(c), in the first embodiment, a portion 131 having a trapezoidal plane of view is formed in a lower portion of the bag body 130. This can improve the independent stability of the gusset container 100 when it is manufactured. Further, in the first embodiment, the cutout portion 125 is formed at the central portion 111e of the lower edge portion while the cutting is performed. The shape of the notch portion 125 is arbitrary, and although it may be a triangle, a quadrangle, a line, or the like, it is preferably semicircular. Since the notch portion 125 is formed in a semicircular shape, the notch portion 125 can be prevented from being broken by external pressure after the gusset container 100 is completed.

As described above, the bag body 130 for the gusset container 100 is completed. The bottom surface portion 124 is then assembled as follows. First, the portion 131 of the bag body 130 on which the gusset film 120 is attached is opened back and forth (see Figs. 5(a) and (b)). Thereafter, the opened portion 131 is folded inward at a predetermined position (see FIG. 5(c)). At this time, since the slit portion 125 is provided in the first embodiment, the central portion 111e of the lower edge portion of the packaging film 110 is easily bent, so that the gusset film 120 can be easily folded inward. As described above, the assembly of the bottom surface portion 124 of the bag body 130 is completed (see Fig. 5(c)). Then, the opening portion (upper edge portion) 132 of the bag body 130 is lifted up, and the side edge portions of both sides are sandwiched by a holder (not shown), and the air is opened into the opening portion, and then the contents are filled. As described above, the opening 132 is sealed, and the product (food or medicine, etc.) of the gusset container 100 is completed (see FIG. 1).

As described above, the gusset container 100 of the first embodiment constitutes the widened portion 122 at the gusset film 120 on both sides, and the lower portion of the gusset film 120 is folded inwardly to constitute the bottom portion 124, and thus the gusset portion The (side surface 102) can be fully deployed to the right and left, so that sufficient volumetric efficiency can be ensured while improving the independence in mounting the gusset container 100.

Further, since the portion (i.e., the upper side edge portion 111a) provided with the side edge portion 111 of the package wrap film 110 constitutes the gusset container 100 having the upper flat shape and the lower portion in a three-dimensional shape, it can be clamped by a holder or the like. The contents are filled into the gusset container 100 while the upper side edge portion 111a is held. As a result, according to the first embodiment, a conventional filler for a stand-up pouch can be used, and the introduction cost is relatively low.

According to the first embodiment, the lower edge portion of the package film 110 is packaged in the central portion 111e of the bottom surface portion 124, while the gusset film 120 is packaged at the lower edge portion of the packaging film 110 outside the central portion 111e thereof, so the gusset film 120 It is easy to fold inward and it is easy to obtain sufficient stable independence. According to the first embodiment, since the notch portion 125 is provided in the central portion 111e of the bottom surface portion 124, it is easier to fold the gusset film 120 inward.

According to the first embodiment, the cutout portion 125 has a nearly semicircular shape, so that the cutout portion 125 is less likely to be broken by external pressure.

According to the manufacturing method of the gusset container 100 of the first embodiment, the pair of gusset film films 120 are respectively bent and inclined, and a pair of wrapping film 110 is inserted, and thereafter, the upper side edge portion 111a of the package wrapping film 110 is assembled. At the same time, by enclosing the outer edge portion 111f of the portion where the pair of wrapping film 110 and the pair of gusset film films 120 are overlapped, the gusset container 100 before filling the contents can be manufactured by a simple procedure. Further, according to the first embodiment, a conventional filler for a stand-up pouch can be used, so that the introduction cost is low.

Hereinafter, a specific embodiment 2 of the present invention will be described with reference to Figs. 6 to 8 . In FIGS. 6 to 8, the same reference numerals as those of FIGS. 1 to 7 respectively show the same compositions as those of FIGS. 1 to 8.

As shown in FIGS. 6 and 7, the shape of the side surface portion and the bottom surface portion of the gusset container 200 according to the second embodiment is different from that of the first embodiment described above. The gusset container 200 of the second embodiment has a configuration in which the side surface 102 formed by the pair of gusset films 120 has only the widened portion 211 and does not have an equal width portion. That is, in the second embodiment, the widened portion 211 has a shape that goes straight to the bottom surface portion 220 of the gusset container 200. Further, in the bottom surface portion 220 of the gusset container 200, a spreader portion 221 having a substantially triangular viewing angle is provided to extend outward in the front and rear directions. Hereinafter, a method of manufacturing the gusset container 100 will be described. First, in the same manner as in the case of the first embodiment (see FIG. 4(a)), the pair of gusset film films 120 are inserted into the pair of wrapping films 110 in a state of being bent outward. At this time, in the same manner as in the first embodiment, the gusset film 120 is mounted in an inclined state in which the lower sides are close to each other, and a part of the upper side and the lower side are projected from the packaging film 110. However, the manufacturing steps of the second embodiment differ from the first embodiment in that the package film 110 is entirely in contact with the lower edge portion 215 except the central portion 214 when the gusset film 120 is attached (refer to FIG. 8(a)). . Then, the packaging film 110 and the gusset film 120 are packaged. Also in the second embodiment, as in the first embodiment, the side edge portion overlapping portion 212 of the packaging film 110 is sealed by heat sealing or the like. The continuously overlapping partial outer edge portions 213 are enclosed in a portion where the wrapping film 110 and the gusset film 120 overlap (refer to Fig. 8(a)). Further, as in the first embodiment, the package of the packaging film 110 is also carried out at the central portion 214 of the lower edge portion while the package is being carried out. Then, in the gusset film 120 and the packaging film 110, the portion protruding from the side edge portion 212 is cut away to complete the shape of the bag body 230 (refer to Fig. 8(b)). At this time, in the same manner as in the first embodiment, at the time of this cutting, the notch portion 125 is formed at the central portion 214 of the lower edge portion.

Hereinafter, the bottom surface portion 220 of the bag body 230 is assembled in the same manner as in the first embodiment (see FIG. 5). In the second embodiment, when the gusset film 120 is inserted into the packaging film 110, the gusset film 120 is brought into contact with the packaging film 110 at the entire lower edge portion 215 except the central portion 214 (refer to FIG. 8(a) Therefore, when the bottom surface portion 220 is assembled, the corner portion 216 of the lower portion of the bag body 230 constitutes the wing portion 221 as it is (see FIG. 8(b)). Thereafter, in the same manner as in the first embodiment, the contents of the bag body 230 are filled, and the product of the gusset container 200 is completed (see FIG. 1). According to the second embodiment, the same effects as those of the first embodiment described above can be obtained. Further, according to the second embodiment, the wing portion 221 extending outward along the front and back directions of the bottom surface portion 220 is attached, so that the independent stability of the gusset container 200 can be higher than that of the gusset container 100 of the first embodiment.

Further, the first and second embodiments described above are described as an example of a container that is applied to the upper portion to be opened and opened, but may be applied to a container with a nozzle.
