(box-shaped state)
As shown in FIGS. 1 and 3, the box-shaped packaging container 100 has an upper surface 110, a lower surface 130, and side surfaces 120 forming a gap (receiving space). A side seal portion 140 and a folded piece 150 are provided along the outer peripheral surface of the side surface 120 . In the packaging container 100, as an example, the side seal portion 140 extends along the side surface 120 with the edge facing the lower surface 130 side.

In the packaging container 100 , one or more folded pieces 150 extend from the side shared by the adjacent side surfaces 120 . Specifically, in the packaging container 100, two folding pieces 150 extend out from sides other than the side shared by the side 120 indicated by the arrow A and the side 120 indicated by the arrow D in FIG. 3(b) as an example. . One of the two folding pieces 150 is provided along each of the adjacent side surfaces 120 . Note that, as in the packaging container 100, a plurality of folded pieces 150 may be provided so as to extend only on some sides of the adjacent side surfaces 120, or on all sides shared by the adjacent side surfaces 120, You may provide so that it may extend in multiple sheets. Moreover, in the packaging container 100, the plurality of folded pieces 150 sharing one side are provided along another side surface 120, but the plurality of folded pieces 150 sharing one side are arranged on the same side surface 120. may be provided so as to overlap with each other.

(flat state)
As shown in FIG. 2, the flat packaging container 100 is composed of a first portion 170a and a second portion 170b that overlap each other. As shown in FIG. 4, the blank for forming the packaging container 100 is composed of a blank 101a corresponding to the first portion 170a and a blank 101b corresponding to the second portion 170b.

The first portion 170a includes the upper surface 110, a plurality of upper isosceles trapezoidal surfaces 120a extending from each side of the upper surface 110, and a plurality of upper folded surfaces formed between the adjacent upper isosceles trapezoidal surfaces 120a. 150a, and an upper sealing margin 140a forming a peripheral edge portion along the edge of the upper isosceles trapezoidal surface 120a and the upper folded surface 150a on the side opposite to the upper surface 110, along the entire circumference of the outer edge of the first portion 170a. .

The second portion 170b includes the lower surface 130, a plurality of lower isosceles trapezoidal surfaces 121b extending from each side of the lower surface 130, and a plurality of lower isosceles trapezoidal surfaces 121b formed between adjacent lower isosceles trapezoidal surfaces 120b. Along the side folded surface 150b, the lower isosceles trapezoidal surface 120b, and the edge opposite to the lower surface 130 of the lower folded surface 150b, the lower side that constitutes the perimeter of the outer edge of the second portion 170b. and a seal allowance 140b.

The upper surface 110 and the lower surface 130 are convex polygonal surfaces. In the packaging container 100, as an example, the upper surface 110 and the lower surface 130 are formed in a congruent shape. For example, the upper surface 110 and the lower surface 130 may have similar shapes with different areas. The shape of the upper surface 110 and the lower surface 130 is not limited as long as it is a convex polygonal shape. An opening 111 is formed in the upper surface 110 .

The plurality of upper isosceles trapezoidal surfaces 120a and the plurality of lower isosceles trapezoidal surfaces 120b are surfaces that constitute the side surfaces 120 of the packaging container 100 in the box-like state. In the packaging container 100, as an example, the upper isosceles trapezoidal surface 120a and the lower isosceles trapezoidal surface 120b are rectangular. At least one of the upper isosceles trapezoidal surface 120a and the lower isosceles trapezoidal surface 120b may have a non-rectangular isosceles trapezoidal shape.

As shown in FIG. 3 , the upper isosceles trapezoidal surface 120 a extends from each side of the upper surface 110 (convex polygonal surface), and one of the two parallel sides is defined as each side of the upper surface 110 . The lower isosceles trapezoidal surface 120 b extends from each side of the lower surface 130 (convex polygonal surface), and one of the two parallel sides is defined as each side of the lower surface 130 . Further, as shown in FIG. 3, the side of the upper isosceles trapezoidal surface 120a on the side of the upper sealing margin 140a and the side of the lower isosceles trapezoidal surface 120b on the side of the lower sealing margin 140b are formed to have the same length. .

The upper folded surface 150a and the lower folded surface 150b are surfaces forming the folded piece 150 of the box-shaped packaging container 100, and are surfaces that are folded in the deformation process described later.

Upper and lower folding surfaces 150a and 150b extend from each vertex of upper and lower surfaces 110 and 130, as indicated by dotted lines in FIG. A fold-back ruled line 151 extending toward the peripheral edge of the second portion 170b is provided.

At least one set of the upper folded surface 150a and the lower folded surface 150b that face each other among the upper folded surface 150a and the lower folded surface 150b has a folded ruled line group 151 consisting of three or more and an odd number of folded ruled lines 151. '. In the case of the packaging container 100, one set of the four pairs of the upper folding surface 150a and the lower folding surface 150b facing each other has the folding ruled line 151, and the three pairs have the folding ruled line group 151'. Although the details will be described later, the upper folding surface 150a and the lower folding surface 150b are provided with folding ruled line groups 151', so that a plurality of folded pieces 150 sharing one side can be formed in the process of deformation.

The upper seal allowance 140a and the lower seal allowance 140b are belt-shaped surfaces provided to connect the first portion 170a and the second portion 170b at their peripheral edges. When connecting the first portion 170a and the second portion 170b, the first portion 170a and the second portion 170b are overlapped so that the upper sealing margin 140a and the lower sealing margin 140b face each other. The side seal portions 140 are formed by sealing, adhering, or the like the surfaces to be connected to each other. The shape of the upper sealing margin 140a and the lower sealing margin 140b can be arbitrarily set as long as there is a sealing margin that overlaps with each other in order to form the side seal portion 140 by overlapping.

Part of the perimeter of the upper folding surface 150a and the lower folding surface 150b with the folding ruled line group 151′ is, as shown in FIG. It is formed inside the extension of the other side (peripheral side side) of the two parallel sides. More specifically, the part of the peripheral edge is the peripheral edge of the upper folded surface 150a and the lower folded surface 150b having the folded ruled line group 151′, and is the upper isosceles trapezoidal surface 120a and the lower isosceles trapezoidal surface. This is the part sandwiched between the pair of fold-back ruled lines 151 closest to 120b.

By designing the shapes of the upper folded surface 150a and the lower folded surface 150b having the folded ruled line group 151', the upper folded surface 150a and the lower folded surface 150b can be made small. Therefore, the side surface 120 is not largely covered with the folded piece 150, and the design is less likely to be impaired. Also, the materials used for manufacturing the packaging container 100 can be reduced.

Also, as shown in the plan view of blank 101a in FIG. 4, each upper folded surface 150a and lower folded surface 150b is closest to the side shared by adjacent upper and lower isosceles trapezoidal surfaces 120a and 120b. The length (L1) of the folding ruled line 151 on the upper folding surface 150a and the lower folding surface 150b is longer than the side (L2) shared by the adjacent upper and lower isosceles trapezoidal surfaces 120a and 120b. is preferred.

By designing the length of the fold-back ruled line 151 in this way, when the packaging container 100 is changed from a flat state to a box-shaped state, the side seal portion 140 on the outer side of the fold-back ruled line 151 indicated by L1 is pulled apart. can be made difficult to remove. Further, when the packaging container 100 is in a box-like state, the edges of the side seal portions 140 can be aligned on a straight line parallel to each side of the upper surface 110 and the lower surface 130, thereby improving the design. .

FIG. 5 shows a perspective view of a packaging container 500 according to a comparative embodiment. The packaging container 500 does not include the fold-back ruled line group 151′, and extends to the extension of the peripheral side of the two parallel sides of the adjacent upper and lower isosceles trapezoidal surfaces 520a and 520b. It has an upper folded surface 550a and a lower folded surface 550b. FIG. 5(a) shows a box-shaped state, and FIG. 5(b) shows a flat state. As shown in FIG. 5, since the packaging container 500 does not have the above features, the folding piece 550 is formed large. Therefore, when the folded piece 550 is laid along the side surface 520, the side surface 520 is largely covered with the folded piece 150, which impairs the design.

The width of the side seal portion 140, that is, the width of the upper seal margin 140a and the lower seal margin 140b may be constant as long as the first portion 170a and the second portion 170b can be connected, or may be constant. It need not be, and the edge need not be straight. For example, the widths of the upper sealing margin 140a and the lower sealing margin 140b are set outward at a predetermined angle toward the folding ruled line 151 and the folding ruled line group 151' outside the upper folding surface 150a and the lower folding surface 150b, respectively. You may form so that it may spread to. By forming in this way, as will be described later, the plurality of upper isosceles trapezoidal surfaces 120a and the plurality of lower isosceles trapezoidal surfaces 120b are formed into a non-rectangular shape, and the side surface 120 is tapered to form a box-shaped packaging container. In the state of (2), the peripheral edges can be formed on straight lines parallel to the sides of the upper surface 110 and the lower surface 130, and the design can be improved.

The area to be sealed can be a belt-like area having a predetermined width, as shown by hatching in FIG. 4, for example. The packaging container 100 formed in this way has airtightness except for the opening 111 .

The blanks 101a and 101b can be formed by, for example, cutting a sheet material into a predetermined shape and providing ruled lines as indicated by thin and dotted lines in FIG.

The sheet material used for the blanks 101a and 101b is not particularly limited, but for example, a laminated film obtained by laminating a thermoplastic resin layer or a sealant layer on a paper base layer can be preferably used. In addition to these, a barrier layer, a functional film, or the like may be added as appropriate depending on the required functions.

(Deformation method)
Next, using the packaging container 100, an example of a method for transforming a flat packaging container into a box-like shape will be described. 6(a) to 6(d) are diagrams for explaining an example of a method for deforming the container body 100. FIG.

First, as shown in (a) of FIG. 6, the first portion 170a and the second portion 170b of the packaging container 100 in a flat state are attached at the periphery (specifically, the side seal portion 140 and the upper side, etc.). (along the crease between the leg trapezoidal surface 120a and the lower isosceles trapezoidal surface 120b) to pull the first portion 170a and the second portion 170b apart. Thereby, a gap is formed between the first portion 170a and the second portion 170b, and the upper surface 110, the lower surface 130, and the side surface 120 are formed. At the same time, the sides of upper and lower folded surfaces 150a and 150b that are shared by adjacent upper and lower isosceles trapezoidal surfaces 120a and 120b are brought closer together. As a result, the upper folding surface 150 a and the lower folding surface 150 b having one folding ruled line 151 are folded along the folding ruled line 151 to form the folded piece 150 .

Further, the folding surface 150a and the folding surface 150b having the folding ruled line group 151' become a plurality of folding pieces 150 that are folded along the folding ruled line group 151' and share one side. Specifically, for example, when the folding ruled line group 151′ is composed of three folding ruled lines 151, the central folding ruled line 151 is folded toward the gap, and the two folding ruled lines 151 sandwiching the folding ruled line 151 are formed in the gap. Two folding pieces 150 are formed by being folded outward. The same applies to the case where the group of folding ruled lines 151' is five or more. Two or more folding ruled lines 151 folded toward the gap and two folding ruled lines 151 sandwiching the folding ruled line 151 extend outward from the gap. Three or more folded pieces 150 are formed by being folded toward each other.

Next, as shown in FIG. 6B, the side seal portion 140 is made to face the lower surface 130 along the side surface 120 . Note that the side seal portion 140 may extend along the side surface 120 toward the upper surface 110 .

Next, as shown in (c) of FIG. 6 , the folded piece 150 is placed along the outer peripheral surface of the side surface 120 . The direction along which the folded pieces 150 are arranged is not limited, and as shown in FIG. Each folded piece 150 may be along a different direction.

At this time, the folding piece 150 may be attached to the surface of the side surface 120 . As a method for attaching the folded piece 150 to the side surface 120, for example, there is a method using a heat seal, a hot melt adhesive, or the like. Moreover, by attaching the packaging container 100 using a detachable joining member such as a hook-and-loop fastener or a snap button, the packaging container 100 that has been deformed from the box-shaped state to the flat state can be used again in the box-shaped state. It becomes possible to reuse the packaging container 100 in a good state.

By the above procedure, as shown in (d) of FIG. 6, the flat packaging container 100 can be transformed into a box shape.

The box-shaped packaging container 100 can be flattened by performing the procedure opposite to that described above.

Specifically, first, the folding piece 150 of the box-shaped packaging container 100 is separated from the side surface 120 .

Next, the first portion 170a and the second portion 170b are extended in the side seal portion 140 (more specifically, along the ruled line between the side seal portion 140 and the side surface 120).

Next, by eliminating the gap between the first portion 170a and the second portion 170b and overlapping the first portion 170a and the second portion 170b, the packaging container 100 is transformed into a flat state. can do.

<Modification>
In the above embodiment, an example of forming a packaging container using two blanks 101a and 101b corresponding to the first portion 170a and the second portion 170b was shown. good too. FIG. 7 shows a blank 102 according to a modified example. As shown in FIG. 7, the blank 102 is connected by a connecting portion 180 at a portion of the peripheral edge of the blank corresponding to the first portion 170a and the second portion 170b.

When forming the packaging container 100 using the blank 102, for example, by folding back at the connecting portion 180, the first portion 170a and the second portion 170b having circular peripheral edges are overlapped, and then, The upper sealing allowance 140a and the lower sealing allowance 140b are sealed. By integrally forming the blanks in this way, for example, when blanks are formed by punching sheet materials, many blanks can be punched from one sheet material, so that packaging containers can be manufactured at low cost. can be done.

When the first portion 170a and the second portion 170b of the packaging container 100 formed using the blank 102 are pulled apart to deform into a box shape, the connecting portion 180 is extended. Also, when deformed into a flat state, the connecting portion 180 is folded back.

Further, in the above-described embodiments and modifications, at least one of the upper isosceles trapezoidal surface 120a and the lower isosceles trapezoidal surface 120b may be formed as a non-rectangular isosceles trapezoidal surface. By forming the upper isosceles trapezoidal surface 120a and the lower isosceles trapezoidal surface 120b in this manner, at least one of the side surfaces 120 above and below the side seal portion 140 of the box-shaped packaging container can be forward tapered or reverse tapered. As a result, it is possible to provide a packaging container having a more highly designed shape.

Also, a spout may be attached to the opening 111 of the packaging container of the present invention. By attaching a spout to which a cap can be attached to the opening 111, the opening 111 can be easily sealed. In addition, by attaching the spout, for example, the packaging container folded flat can be transformed into a box shape, filled with a content such as a liquid, and then the opening 111 can be sealed using a cap or the like. For this reason, for example, there is no need for a sealing process for ensuring hermeticity in the filling line of contents, and it becomes unnecessary to guarantee sealing performance in the filling line. Therefore, by using the packaging container of the present invention, it is possible to efficiently fill the contents.

Moreover, according to the packaging container of the present invention, the packaging container can be transported in a flat state, so that the loading efficiency of the packaging container is good, and transportation and storage costs can be reduced.
