[Embodiment 1]

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, a gusset container 100 according to the first embodiment has a pair of outer film 110 and a pair of gusset film 120, and has a bag shape having a slightly rectangular front view. A pair of exterior film 110 is used to form the surface 101 of the gusset container 100 and the inside (not shown). Of the side edge portions 111 of the exterior film 110, the upper side edge portion 111a (i.e., the portion from the upper end of the exterior 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 preferably, the size of the holder for holding the gusset container 100, etc., according to the entire size of the gusset container 100 and the step of filling the contents inward (described later). The data is preferably determined, for example, about 40 to 50 mm.

In the side edge portion 111 of the exterior film 110, the lower side edge portion 111b (that is, the portion from the lower end of the upper side edge portion 111a to the lower end portion of the side edge portion 111 in the side edge portion 111 of the exterior 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 widened portion side edge portion 121a is expanded 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 and the equal-width side edge portion 121b on both sides are almost in the same shape (see FIG. 3(b)). The width portion 123 is encapsulated in the exterior film by the side edge portion 121 of the gusset container 100 (that is, the flared side edge portion 121a of the widened portion 122 and the equal width portion side edge portion 121b of the equal width portion 123). In a state of the lower side edge portion 111b of the 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. The upper edge portion 112 (described later) of the gusset container 100 is encapsulated by filling the contents inwardly in the gusset container.

Further, when the side edge portion 121 of the gusset film 120 is packaged to the lower side edge portion 111b of the exterior film 110, the outer film 110 is directly sealed between the central portion 111e of the lower edge portion, and at the same time A substantially central portion of the package portion is preferably formed as a semicircular cutout portion 125 (see FIGS. 4 and 5). Thus, the gusset film 120 is relatively easy to fold inward. The size of each portion of the gusset container 100 is arbitrary.

Further, the material for forming the exterior film 110 and the gusset film 120 is also arbitrary, but a material for sealing the package for sealing can be used.

Hereinafter, according to a method of manufacturing the gusset container 100, 4 and 5 are used. The figure is explained. First, a bag body 130 for a gusset container 100 as shown below is produced. First, the pair of gusset film films 120 are bent outward (even if the fold line faces inward), and an external film 110 is sandwiched (see Figs. 4(a) and 4(b)). At this time, the gusset film 120 is mounted so as to be inclined toward the lower side, and a part of the upper side to the lower side is extended from the exterior film 110, even if the gusset film 120 is on the side of the exterior film 110. In the edge portion 111, the portion (side edge portion 111c) formed by the upper side edge portion 111a or the both end portions 111d or the center portion 111e of the lower edge portion are not provided in contact with the exterior film 110.

The encapsulation of the exterior film 110 and the gusset film 120 is performed below (see Fig. 4(b)). In this packaging process, the overlapping portion between the side edge portions 111 of the exterior film 110 (i.e., the side edge portion 111c) is packaged in the overlapping portion of the exterior film 120. The outer edge portion 111f of the continuously overlapping portion is packaged on the exterior film. Further, in the first embodiment, the package is mounted, and the package is also disposed between the central portion 111e of the lower edge portion and the exterior film 110. Thereafter, in the gusset film 120 and the exterior 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 planar shape is formed in the lower portion of the bag body 130. This can improve the standing 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 being 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.

First, the bag body 130 is provided with a portion 131 of the gusset film 120, Open before and after (refer to Figure 5 (a), (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 exterior 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 (upper edge portion) 132 of the bag body 130 is lifted up, and the side edge portions of both of them are sandwiched by a holder (not shown), and the injecting air opening portion is expanded, and then the contents are filled inward. As described above, the opening 132 is sealed to complete a product (food, medicine, etc.) contained in the gusset container 100 (see Fig. 1).

As described above, in the gusset container 100 of the first embodiment, the widened portion 122 is formed at the gusset film 120 on both sides, and the lower portion of the gusset film 120 is folded inwardly to form the bottom portion 124. Therefore, the gusset portion (side surface 102) can be sufficiently expanded to the left and right, so that it is possible to ensure sufficient volumetric efficiency while improving the standing property when the gusset container 100 is mounted.

In addition, since a portion (ie, an upper side edge portion 111a) that is provided between the side edge portions 111 of the packaged exterior film 110 is provided, a gusset container 100 having a flat shape in the upper portion and a three-dimensional shape in the lower portion is provided. The contents are filled inwardly into the inside of the gusset container 100 in a state where the upper side edge portion 111a is held by a gripper or the like. As a result, according to the first embodiment, a conventional filler for a standing bag can be used, so that the introduction cost is relatively low.

According to the first embodiment, the center portion 111e of the bottom surface portion 124 encloses the lower edge portion of the exterior film 110, and the gusset film 120 is packaged at the lower edge portion of the exterior film 110 except for the central portion 111e thereof. The gusset film 120 is easily folded inwardly, and it is easy to obtain sufficient standing stability. According to the first embodiment, the central portion 111e of the bottom surface portion 124 The slit portion 125 is provided, so that 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, sandwiching an exterior film 110, and thereafter, on the upper side edge portion of the package exterior film 110. At the same time as the 111a, the outer edge portion 111f of the portion where the pair of outer film 110 and the pair of gusset film 120 are overlapped can be manufactured, and a corner before filling the contents can be manufactured by a simple process.
