Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to an assembled paper box using cardboard. However, in the present invention, cardboard is a general term for cardboard and similar plate-like materials, and includes resin-treated cardboard and synthetic resin sheets molded into cardboard shapes.

[Background of the idea]

Assembled paper boxes are widely used for packaging products, etc., and hollow polygonal column-shaped boxes and semi-cylindrical boxes are in practical use. Among these, hollow hexagonal cylindrical assembled paper boxes have an interesting design and are suitable for packaging products for sale in stores.

The common advantages of these assembled paper boxes are that they can be cut out from a single piece of cardboard (including press punching) and quickly and easily assembled into a three-dimensional shape;
It should not be bulky during storage and transportation.

However, although the hollow hexagonal cylindrical assembled paper box has the above-mentioned advantages and is excellent in terms of design, it has the disadvantage that it is not strong enough to hold its shape in the assembled state.

If the contents can maintain their shape by themselves, such as yokan, the above drawbacks will not be much of a problem, but when used to package products that are difficult to maintain a fixed shape by themselves, such as green tea, for example. The above-mentioned drawbacks are a problem.

[Purpose of invention]

This idea was created in view of the above-mentioned circumstances.
To provide a hexagonal cylindrical assembled paper box that has a strong shape retention force in an assembled state without impairing the inherent advantages of an assembled paper box such as easy manufacture, storage, transportation, and assembly.

[Summary of the idea]

In order to achieve the above object, the assembled paper box of the present invention has a bottom side, a pair of side sides that are substantially perpendicular to both ends of the base side, and a pure angle to the upper end of the pair of side sides. Assuming a hexagon consisting of a pair of touching hypotenuses and an apex that is parallel to the base and shorter than the base connecting the pair of hypotenuses, and assuming a pentagonal prism whose end face forms the above hexagon, A hexagonal cylinder consisting of a bottom surface, a pair of side surfaces, a pair of slopes, and a top surface of the hexagonal cylinder is developed, and a shape in which six rectangles and overlapping parts are connected is set on cardboard, and the above-mentioned hexagonal cylinder is Continuous bent pieces are provided on both ends of the side, slope, and top surfaces, and among the above bent pieces, the bent pieces that are continuous on the top surface have a hexagonal end surface when folded. A side is provided that touches the bottom side, and a sandwiched piece that comes into contact with the bottom surface is provided on the side that touches this bottom side, and among the above-mentioned folded pieces, a pair of folded pieces that are continuous with the slope are these. When bent, the shape intersects on the hexagonal surface of the end face, and the tip thereof has a side touching the base, and the side touching the base is provided with a sandwiching piece that comes into contact with the bottom, and the outline of the above shape is formed. It is characterized in that a cardboard is cut out along the lines, this is bent to form a hexagonal tube shape, and the bent pieces provided at the ends are respectively bent to cover the hexagonal openings at the ends.

[Example of idea]

Next, one embodiment of the present invention will be described with reference to FIGS. 1 to 8.

FIG. 1 is an explanatory diagram of the basic structure of the assembled paper box of the present invention, and A is a hexagonal end face thereof.

For convenience of explanation, a state in which the base a of the hexagon A is horizontal will be described.

A pair of sides b and b' that touch both ends of the base a are set vertically.

The apex c, which is shorter than the base a, is set parallel to the base a and higher than the upper ends of the sides b and b'.

The upper ends of the sides b and b' and the upper end of the apex c are connected by the hypotenuses d and d', respectively, to define a hexagon A. The dimensions of each side can be set arbitrarily, but the sides b and
b' is set to form an obtuse angle with the hypotenuse d, d'.

Assume a hexagonal prism 1 whose end faces are the hexagons A described above. 1a is a bottom surface, 1b and 1b' are side surfaces, 1c is a top surface, and 1d and 1d' are slopes.

The bottom, sides, and top of the hexagonal prism as described above,
Assuming a hexagonal prism made of slopes, if you expand it onto a plane, it will become six rectangles 2a, 2b, 2d, 2c, 2d', 2b' with spots as shown in Figure 2. 2a' is the tongue piece that overlaps the bottom surface 2a,
2b'' shown with spots is a folded piece that overlaps the side surface 2b', and 2a'' is a hole for inserting the tongue piece 2a.

FIG. 3 shows an end view of a paper cylinder 3 made by cutting out a cardboard along the developed figure as described above and folding it into a cylinder. 3a is a bottom plate, 3b and 3b' are side plates, 3d and 3d' are slope plates, and 3c is a top plate.

As shown in FIG. 2, bent pieces are provided at both ends of each of the six rectangles.

2 _b-1 is a bent piece connected to both ends of the expanded side surface 2b.

2 _d-1 is a bent piece connected to both ends of the unfolded slope 2 d, and 2 _d-2 is a sandwiched piece connected to the tip thereof.

2 _c-1 is a folded piece continuous to both ends of the unfolded top surface 2 c, and 2 _c-2 is a sandwiched piece continuous to the tip thereof.

2 _d-1 ′ is a bent piece continuous to both ends of the developed slope 2 d′, and 2 _d-2 ′ is a sandwiched piece continuous to the tip thereof.

2 _b-1 ′ is a bent piece connected to both ends of the expanded side surface 2 b ′.

As mentioned above, the bent pieces 2 _b-1 , 2 _d-1 , 2 _c-1 , 2 _d-
1 ′, 2 _b-1 ′ and sandwiched pieces 2 _d-2 , 2 _c-2 , 2 _d-2 ′ are provided, and cardboard is cut out along the outline of these connected figures to form a cylinder. The end view of the above-mentioned folded pieces in a state in which they are not folded looks like the hexagonal paper cylinder 3 shown by solid lines in FIG. The imaginary line shows the shape of the bent piece when it is bent outward. The details of the shape of these bent pieces will be described later with reference to FIGS. 5 to 7.

From the state shown in FIG. 3, when the bent pieces 3 _b-1 and 3 _{b-1' connected to the side plates 3b and 3b} ' are bent inward by about 90 degrees, the state shown in FIG. 4 is obtained.

FIG. 5 further shows a state in which the bending plate 3 _d-1 connected to the slope plate 3 d is bent inward at right angles.
This bending plate 3 _d-1 is preset in a shape such that its tip touches the bottom plate 3a when bent.Furthermore, the bending plate 3 d-1 is connected to the slope plate _3d on the right side in this figure. ₁ is preset in such a shape that when bent inward, it diagonally crosses the hexagonal end face and contacts the left half of the bottom plate 3a.

A sandwiching plate 3 _d connected to the tip of the bending plate 3 _d-1
-2 is inserted between the bottom plate 3a and the contents B to be clamped.

When the other bent plate 3 _d-1 ′ is further bent, the pair of bent plates 3 _d-1 and 3 _d-1 ′ intersect as shown in FIG. 6, and the cross-sectional shape of the hexagonal paper cylinder 3 is changed. We will firmly support them so that they do not change.

Fig. 7 shows an end view of the state in which the folding plate 3c _-1 connected to the top plate 3c is further folded back inward and the sandwiching plate 3c _-2 is inserted, and Fig. 8 is a perspective view of the above state. It is a diagram.

The folding plate 3 _c-1 is set in advance so that when folded back, its tip touches the bottom plate 3a. This folding plate 3 _c-1 is the above-mentioned folding plate 3 _d-1 ,
3 _d-2 is pressed down and held, and the folding plate 3 _c-1 itself also firmly holds the hexagonal cylindrical shape of the paper tube 3.

The assembled paper box of the embodiment described above can be easily constructed by cutting out a piece of cardboard (or punching it out with a press) as shown in Figure 2, and can be stored or transported as is. It is convenient and not bulky. It can be quickly and easily assembled as shown in FIGS. 3 to 7, and in the assembled state, a pair of bent plates (one The hexagonal cylindrical shape is firmly maintained by the action of 3 _d-1 and 3 _d-1 ' (two pairs are provided per assembled paper box).
