しうる。 (Industrial Application Field) The present invention is a container for storing liquids such as milk and alcoholic beverages, solids such as sugar and salt, and various other contents, and in particular, a container whose crown or bottom is constructed by overlapping folded flaps. Concerning containers. (Prior Art) Conventionally, containers of this type with various structures are known, but the overlapping crown or bottom portion of the fold-in flaps is such that the ends of the flaps are exposed inside the container and the contents are not contained. Penetration caused the liquid to leak and the container to lose its shape. Furthermore, since the sealability of the container is not sufficient, not only the contents may escape from the inside of the container, but also the contents such as liquids and solids may change due to the influence of humidity in the outside air. (Problem to be solved by the present invention) The problem to be solved by the present invention is that the shape of the folding flap and the configuration of the folding means prevent the end of the folding flap from being exposed to the inner surface of the container, allowing the contents to be removed from the top or bottom of the container. The purpose of the present invention is to provide a container that does not permeate or leak and has excellent sealing performance. Further, it is easy to mold, and the flatness of the folded-in crown or bottom is ensured to provide a stable container. (Means for solving the problem) In order to achieve this purpose, the container of the present invention has the following features:
Surrounded by a pair of long-side panels 1, long-side panels 3, and short-side panels 2 and 4 with a bonded part 6 in the center, the horizontal cross section is rectangular, and the crown or bottom is composed of overlapping folded flaps. In the container, the inner flap 9 of the extended part of the long side panel 1 has a base angle of 45 degrees, with the edge 11 of the long side panel 1 as the bottom side and the width of the bonded part 6 as the top side, and a height H forms a trapezoid K that is longer than one half of the edge 18 of the short side panel 2, and a trapezoid K is formed on the inside flap 9 of the extension of the long side panel 3, with the edge 13 of the long side panel 1 as the base and both bottoms. A trapezoid A is formed with an angle of 45 degrees and a height h that is half of the edge 18 of the short side panel 2, and the upper side 14 of the trapezoid A is one side.
and the end of the inner flap 9, a rectangle D surrounded by
Then, form a right isosceles triangle E with the short side 17 of the rectangle D as one side of the isosceles on both sides of the rectangle D, fold the rectangle D outward at the upper side 14 of the trapezoid A, and at the same time form a right isosceles triangle E. It is joined to the back surface of the rectangle D, then the tip of the trapezoid K is aligned with the back surface of the rectangle D, and both outer flaps 10 are overlapped and joined together. (Function) The unfolded drawing of the container is made by folding the long side panels 1 and 3 and the short side panels 2 and 4 outward from the vertical fold line 5, and pasting together the central bonding part 6 to form a square cylinder with a rectangular horizontal cross section. Formed on the body, internal flaps 9,9
and the outer flaps 10, 10 are folded in, respectively. One inner flap 9 is folded in first.
The rectangle D is folded outward at the upper side 14 of the trapezoid A, and the right isosceles triangle E is folded outward and inward from the vertical polygonal line 17 and the inclined polygonal line 16, respectively, and joined to the back side of the rectangle D, so the rectangle D,
The ends of the right isosceles triangle E and the quadrilateral M, that is, the ends of the inner flap 9, do not directly face the interior of the container. The other inner flap 9 to be folded in next is made by folding the tip of the trapezoid K inwards from the inclined fold line 12 and overlapping it on the back surface of the rectangle D. However, the height h of the trapezoid A included in one inner flap 9 is short. This is because the height H of the trapezoid K included in the other inner flap 9 is longer than the half of the edge 18 of the short side panel 2, whereas the height H of the trapezoid K included in the other inner flap 9 is longer than the half of the edge 18 of the short side panel 2. , the end portion including the bonded portion 6 does not directly face the inside of the container. Since the ends of the outer flaps 10 superimposed on the inner flaps 9, 9 do not directly face the inside of the container, the ends of the inner and outer flaps 9, 10 are never exposed inside the container. One inner flap 9 folds the rectangle D outward at the upper side 14 of the trapezoid A, and at the same time joins the right isosceles triangle E to the back side of the rectangle D. Therefore, the right isosceles triangle E on both sides of the rectangle D is , is folded between the folded rectangle D and the square M. The overlap between one inner flap 9 and the other inner flap 9 means that the other inner flap 9 overlaps with the other inner flap 9.
This is done with the tip of the trapezoid K entering the back side of the rectangle D of one of the inner flaps 9, but the trapezoid A that is continuous with the rectangle D and both base angles of the trapezoid K are both
45 degrees, and since the two right-angled isosceles triangles E are folded between the rectangle D and the quadrilateral F, the tip of the trapezoid K smoothly enters the back surface of the rectangle D. Since the right isosceles triangle E folded between rectangle D and quadrilateral M is joined to the back side of rectangle D, and the tip of trapezoid K is overlapped on the back side of rectangle D,
The number of overlapping layers in the central part of the inner and outer flaps 9, 10 can be reduced. Looking at the overlap at the center after molding, the right isosceles triangle E only overlaps with the trapezoid A, the rectangle D, the quadrangle M, and the outer flap 10, and the number of partially overlapped layers is five at most. In the case of the maximum number of overlapping layers (5 layers), the thickness is not very large, and these 5 layers exist in a planar shape with a considerable amount of space.
A folded crown or bottom can easily maintain flatness.

ある。 Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a developed view of a container showing one embodiment of the present invention, which is made of, for example, paperboard surface-coated with thermoplastic synthetic resin, and has a pair of long-side panels 1 and a long-side panel 1 having a bonding portion 6. Panel 3 and short side panels 2 and 4 are divided by vertical fold lines 5. Further, with respect to a box-shaped trunk forming portion made up of long side panels 1, 3, short side panels 2, 4, and bonded portion 6, flaps that form a crown or bottom portion by folding are arranged at upper and lower positions. One long-side panel 1 consists of half-cut panels 1a and 1b divided into two at the center, and has bonded parts 6 at the edges of the half-cut panels 1a and 1b. In addition, one of the long side panels 1 has an inner flap 9 in its extension, which includes an edge 11 of the long side panel and a direction extending from the edge of the edge 11 to the edge of the inner flap 9. The inclined fold line 12 allows the edge 1 of the long side panel to
A trapezoid K of height H is formed with 1 as the base and the width of the bonded portion 6 as the top. This trapezoid K has both base angles of 45 degrees, and the height H is the edge 1 of the short side panel 2.
It is set longer than 1/2 of 8. The other long side panel 3 also has an inner flap 9 on its extension, which has an edge 13 of the long side panel as its base and a bottom edge 13 of the long side panel.
The upper side 14 is a horizontal line parallel to , and the inclined line 15 from both ends of the edge 13 of the long side panel to the upper side 14 makes both base angles 45 degrees and the height h is 2 of the edge 18 of the short side panel 2. A trapezoid A is formed. A rectangle D is formed outside the upper side 14 of the trapezoid A and is surrounded by the upper side 14 of the trapezoid A and the end of the inner flap 9, with the upper side 14 of the trapezoid A as one side. That is, the rectangle D has a pair of long sides that are opposite to each other, the upper side 14 of the trapezoid A and the end of the inner flap 9, and a short side 17 that is a vertical line connecting the two ends. A right isosceles triangle E having the short side 17 as one isosceles side is formed on both sides of the short side of the rectangle D.
That is, from the short side 17 of the rectangle D, the edge of the inner flap 9, and both ends of the upper side 14, the inner flap 9
A right-angled isosceles triangle E, which has a right angle opposite to the inclined polygonal line 16 and has the short side 17 of the rectangle D as one isosceles side, is formed by the diagonal polygonal line 16 toward the edge of the rectangle. A quadrilateral M is formed on both outer sides of the trapezoid A and the right isosceles triangle E by inclined polygonal lines 15, 16 and vertical polygonal lines 5. and inner flaps 9, 9 and outer flap 1
0 and 10 are respectively folded outward from the edges 11 and 13 of the long side panel and the edge 18 of the short side panel, and then folded inside each other. That is, first, one of the inner flaps 9 is turned inward, and the rectangle D of the inner flap 9 is folded inwards at the upper side 14 of the trapezoid A to be folded outward, and at the same time, the right isosceles triangle E is folded outward from the vertical fold line 17. At the same time, the inclined polygonal line 16
It is further folded inward and folded between rectangle D and quadrilateral M, and the thus folded isosceles right triangle E is joined to the back surface of rectangle D. The other inner flap 9 is directed inward, and the tip of the trapezoid K of the other inner flap 9 is overlapped with the back surface of the rectangle D of one inner flap 9. Then, both outer flaps 10, 10 are folded into the inner flaps 9, 9, overlapped with the inner flaps 9, 9, and joined together. This integral joining closes the bottom of the container consisting of the inner flaps 9, 9 and the outer flaps 10, 10 and forms a bottom of the container with a flat surface. In addition to heat sealing, gluing, etc., various known fixing methods can be used for joining.
Furthermore, the paperboard constituting the container can be made of various other materials and structures. In addition, although in the illustrated embodiment the container top has a gable-shaped closure structure, which is well known in the art, the container top can also have the same structure as the bottom. As shown in FIGS. 4 and 5, the section J can be configured in various shapes provided that the height H of the bonded portion 6 of the inner flap 9 is regulated. (Effect of the invention) In the container of the present invention, due to the shape of the folding flap and the configuration of the folding means, the end of the folding flap is not exposed to the inner surface of the container, and the contents do not permeate or leak from the crown or bottom. It has the effect of excellent sealing performance. Furthermore, since the number of overlapping flaps in the crown or bottom can be reduced, molding is easy, and the flatness of the folded-in crown or bottom is ensured, resulting in excellent stability in container arrangement. Therefore, not only can the contents be removed from the inside of the container, but the contents, such as liquids and solids, cannot be affected by moisture in the outside air, and the contents can be kept sealed and stored in a stable state. It is particularly effective for
