Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging container suitable for accommodating cakes and the like.

[Prior Art] Various types of assembly-type packaging containers have been known in the past.

Most of these packaging containers are folded and flat before being assembled, but most of them have a rectangular parallelepiped shape when assembled.

Furthermore, the handle is simply cut and raised from the top of the container.

[Problems to be solved by the invention] Conventional containers such as those described above have a rectangular parallelepiped shape when assembled, are difficult to change in external shape, and are difficult to distinguish from other containers except for the printed pattern.
The product value as a container is low.

Another problem was that the handle had no other function and hardly contributed to changing the external shape of the container.

The present invention aims to provide a packaging container that takes a truncated pyramid shape when in use and can be easily distinguished from other containers, and that can accurately retain its truncated pyramid shape by overlapping handles. It is something.

[Means for solving the problem] In the present invention, a piece of paper is punched out from a continuous piece of cardboard, two sets of opposing side plates are made into a trapezoid shape, and the top plate part is divided into left and right parts, which are continuous at the handle part. ,
By cutting and raising the handle, the separated parts of the top plate are overlapped to form a similar shape that is one size smaller than the bottom plate, resulting in a truncated pyramid-shaped packaging container as a whole.
The bases of the handles, which are cut up and stacked one on top of the other, are guided into the elongated holes on the side plate side through bent cuts.

[Effect]

If the structure described above is adopted, the container will have a truncated pyramid shape when assembled, and its appearance will be completely different from other containers, making it easy to distinguish it from other containers.By giving the handle the function of changing the shape of the container, The commercial value of the container can be improved.

〔Example〕

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 and subsequent figures illustrate one embodiment of the present invention, and FIG. 1 shows the packaging container of the present invention in an unfolded state.

The container 1 of the present invention is continuously punched out of a piece of cardboard, and a square bottom plate 2 is formed at one end thereof.

An adhesive margin 4 is continuous to the outer edge of the bottom plate 2 via a fold line 3.

Moreover, trapezoidal side plates 6 are continuously formed on both left and right edges of the bottom plate 2, and on both upper and lower edges in FIG. 1, via fold lines 5, 5.

A triangular bent piece 8 is continuously formed at the outer end of the trapezoidal side plates 6, 6 via a fold line 7 parallel to the fold line 5. A long hole 9 is formed in the center of each bent piece 8 over a predetermined length on a straight line connecting the apex of the triangle and the center of the base.

A notch 9a is formed from the outer end of each elongated hole 9 toward one of the oblique sides of the bent piece 8.

The cuts 9a, 9a are formed in opposite directions and slightly inclined outward.

Further, a trapezoidal side plate 1 having the same size as the side plate 6 is provided at the inner end of the bottom plate 2 via a broken line 10.
1 are formed consecutively.

The left and right edges of this side plate 11 form fold lines 12, and a folded piece 13 is continuously formed through these fold lines 12.

The side of this bent piece 13 on the side plate 6 side is
The length of the opposite side is shorter than the length of this side, and the side connecting the outer ends of both pieces is not parallel to the fold line 12.

A top plate 15 is continuously formed on the side plate 11 via a broken line 14.

This top plate 15 is formed in a rectangular shape with a short side having the length of the broken line 14, and the length of the long side is equal to the length of one side of the bottom plate 2.

A handle 16 is punched out in the center of the top plate 15.

This handle 16 has a substantially E-shape in which U-shapes are joined back to back, and is formed symmetrically, with a fold line 17 formed on its axis.

Further, the upper, lower, left and right leg-like ends of the handle 16 are continuous to the top plate 15 via fold lines 18 parallel to the fold lines 17.

Furthermore, flat triangular openings 19 are formed at the upper and lower ends of the handle 16.

On the other hand, each of the long side edges of the top plate 15 has a fold line 2.
The side plate 21 is formed continuously through the side plate 0.

The base of each side plate 21 has oblique sides 22 on its left and right sides, and its tip extends linearly.

This side plate 21 is divided into two symmetrical bent pieces 21a and 21b by a notch 21c formed on a straight line passing through the fold line 17 of the handle 16.

The notch 21c extends from the outer end of the side plate 21 to the opening 1.
It has reached 9.

That is, the top plate 15 is divided into two continuous parts, right and left, only through the fold line 18 of the handle 16.

There is a fold line 2 on the short side of the top plate 15 opposite to the fold line 14.
A side plate 24 is formed continuously through the side plate 3.

This side plate 24 is formed into a trapezoidal shape like the side plate 11, and is arranged symmetrically with the side plate 11 with the top plate 15 in between.

A substantially trapezoidal bent piece 26 is continuously formed at both left and right ends of the side plate 24 via a folding line 25 .

Next, a method for assembling the container according to the present invention, which has been punched out as described above, will be explained.

First, from the state shown in FIG. 1, the top plate 15 is turned over at the fold line 15 so that it overlaps the side plates 11 and the bottom plate 2, and the adhesive margin 4 is attached to the back surface of the tip of the side plate 24.

At this time, the adhesive margin 4 is valley-folded from the fold line 3 and pasted. This state is shown in FIG.

In this state, the container is folded flat and is stored or transported in this state.

To assemble the container at a store, etc., from the state shown in FIG. 2 to the left and right side plates 11 and 2 as shown in FIG.
Raise 4 at a right angle.

Next, bend pieces 1 at both ends of the left and right side plates 11 and 24.
3 and 26 inward from fold lines 12 and 25.

At the same time, when the handle 16 is mountain-folded from the fold line 17, the top plate 15 is divided into left and right halves by the notch 21c, so the divided parts are attracted.
One side will be overlaid on top of the other.

The handle 16 is then completely folded in half and overlapped, as shown in FIG.

As a result, the left and right side plates 11, 24 are inclined with their upper ends approaching each other, and the fold lines 12, 1
The space surrounded by 4, 23, 25 and the bottom plate 2 has a trapezoidal shape.

The size of the trapezoid at this time is the same size as the trapezoid of the side plate 6 which is continuous with the bottom plate 2.

In this state, the bent piece 21 continuous to the top plate 15
a and 21b are also in an overlapping state.

Subsequently, the overlapping folded pieces 21a and 21b are mountain-folded from the fold line 20, and stacked on the outside of the folded pieces 13 and 26.

Then, the trapezoidal side plates 6, 6 are stacked on the outside of the folded pieces 21a, 21b, which are each bent from the fold line 5 in a valley fold.

Next, bend the bent piece 8 from the fold line 7 to form the top plate 1.
5, and push the base of the handle 16 into the elongated hole 9 while pushing out the notch 9a.

Then, the long hole 9 is located at the back of the bent piece 8, the notch 9a is linear, and the long hole 9 and the notch 9a are
Since the handle 16 has a continuous bent structure, the base of the handle 16 is extremely difficult to come off, and the container maintains its truncated pyramid shape and does not lose its shape.

In this embodiment, the notches 9a and 9b face in opposite directions, so that even if force is applied from either direction, a force is applied that prevents one from coming off, resulting in a container that is extremely resistant to deformation. ,
Safely protect stored cakes, etc.

In addition, when storing cakes or the like, it is sufficient to do so when the side plates 11 and 24 are erected as shown in FIG.

Incidentally, when it is desired to take out the contents, the base portions of the overlapping handles 16 can be pulled out from the elongated hole 9 through the notch 9a.

〔effect〕

As is clear from the above description, according to the present invention, each part constituting the container is punched out of a single continuous piece of cardboard, the two sets of opposing side plates are shaped like a trapezoid, the top plate is divided into left and right parts, and the handle is separated. By cutting and raising the handle, the separated parts of the top plate can be overlapped to create a similar shape that is one size smaller than the bottom plate, so the overall shape is a truncated pyramid, and it fits securely with other containers. A distinguishable packaging container is obtained.

In addition, the bases of the handles, which are cut and raised and stacked one on top of the other, are guided into the long holes on the side plate through bent cuts, so they are extremely difficult to fall off, and the handles are also stacked on top of each other. Since the container is strongly held in its original state, the overlapping handles do not spread out, and a packaging container that does not lose its shape as a whole can be obtained.
