Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to an assembled paper box.

[Conventional technology]

As a conventional assembled paper box, for example, as shown in FIG. 4, a part of a paper pattern 101 cut into a predetermined shape is glued 103' in advance, and each part of the paper pattern 101 is bent and engaged. Therefore, devices that are constructed so that they can be assembled into a predetermined shape are well known.

That is, the paper pattern 101 is as shown in FIG.
First to fourth peripheral wall portions 103a to 1 arranged in parallel in the horizontal direction
03d, and the first to fourth upper wall portions 104a to 104a, which are connected to one end edge in the longitudinal direction of each of the peripheral wall portions 103a to 103d, respectively.
104d, and the first to fourth lines connected to the other edges, respectively.
Bottom wall portions 102a to 102d and first peripheral wall portion 103
It is cut into a shape with a glue margin 103e continuous to the edge in the width direction of a, and folding lines 112 are carved on the boundaries of each part.

This paper pattern 101 has been prepared in advance by the second peripheral wall portion 103b.
and the third circumferential wall 103c along the folding line 112', and fold in the glue allowance 103e to attach the glue 10 to the edge in the width direction of the fourth circumferential wall 103d.
It is manufactured in a 3' folded form.

The paper box 101' shown in FIG. 4 is assembled by folding and engaging each part of the paper pattern 101 manufactured in the folded form as follows.

First, each of the peripheral wall portions 103a to 103d is bent along each bending line 112 to form a rectangular annular peripheral wall 104.
Assemble to.

Next, the bottom wall portions 102a to 102d are bent along the folding line 1.
12... and engage each other to assemble the bottom wall 102. That is, the first bottom wall portion 102a, the second and fourth bottom wall portions 102b, 1
02d is sequentially bent inward, and the engaging protrusions 102'b of the second and fourth bottom wall parts 102b, 102d,
102'd are respectively inserted into the peripheral wall 103 from the concave edge 102'a of the first bottom wall part 102a, so that the bottom wall parts 102a, 102b, and 102d are engaged with each other. Furthermore, the third bottom wall portion 102c is bent inward so that the engaging protrusion 102'c is connected to the concave edge 102'.
2′a to the first bottom wall portion 102a and the engaging protrusion 1
02'c, 102'd, bottom wall part 1
02a to 102d are engaged and integrated with each other.

Then, after storing an object such as a cake on the bottom wall 102, the upper wall portions 104a to 104d are bent along the folding lines 112 and engaged with each other to assemble the upper wall 104. That is, the second and fourth bottom wall parts 102c and 102d are bent inward, and the third top wall part 104c and the first top wall part 104a are bent inward.
The engaging projections 104'a of the first top wall 104a are inserted into the slits 104'c of the third bottom wall 104c.

[The problem that the idea aims to solve]

However, for such a paper box 101',
Since the bottom wall 102 is constructed by mutual engagement of the bottom wall parts 102a to 102d, its strength is weak, and if it is carried around roughly, the bottom wall part 102
There is a risk that the engagement between a to 102d will be released and the object to be accommodated will fall off. Moreover, not only the top wall 104 but also the bottom wall 102 are assembled by engagement, and this bottom wall portion 102 is assembled with the bottom wall portion 102.
Since it has a complicated engagement structure in which the elements a to 102d are superimposed on each other, it is difficult to assemble it easily, and only a certain level of skill is required to quickly assemble it.

Further, the peripheral wall 104 is glued, and the bottom wall 10
Since the top part 2 cannot be completely opened, the peripheral wall 104 becomes an obstacle, making it difficult to store and take out the stored items. In particular, when the object to be accommodated is a fragile cake or the like, or when the object is accommodated in close contact with the peripheral wall 104, it is extremely difficult to accommodate and take out the object.

The object of the present invention is to solve all of these problems and provide an assembled paper box that is easy to assemble and has excellent ease of accommodating, taking out, and transporting items.

[Means for Solving the Problem] The assembled paper box of the present invention that solves this problem has a quadrilateral bottom wall portion and a quadrilateral first wall portion rising from one opposing edge of the bottom wall portion in an opposing manner. a peripheral wall portion, a quadrilateral second peripheral wall portion that rises in opposing directions from the other opposing edge of the bottom wall portion, and whose opposite end portions abut against the side ends of each of the first peripheral wall portions; A first upper wall portion extending in opposing directions from the upper end edge of the first peripheral wall portion; and a quadrilateral second upper wall portion extending in opposing directions from the upper end edges of both second peripheral wall portions and overlapping the first upper wall portion. and a handle portion rising from opposing edges of both second upper wall portions and abutting each other;
A slit bored at the boundary between each first peripheral wall and the first upper wall, and an engaging tongue hanging from both side edges of each second upper wall and inserted into each of the slits. a handle holder extending in opposite directions from each side edge of both second peripheral wall parts and having at least the tip portions overlapped with each other; and an engagement hole bored in the tip portion of each handle holder; and an engaging protrusion formed on each side end of the handle part and inserted into and engaged with each of the engaging holes in an abutting state, and each engaging tongue and engaging protrusion and each engaging protrusion. The structure is such that each part can be unfolded on the same plane by releasing the engagement with the slit and the engagement hole.

[Effect]

It can be assembled into a predetermined box shape by bending each part along the boundary lines with other parts and inserting and engaging each engaging tongue into each slit. Such insertion engagement can be easily performed, unlike the overlapping engagement of the peripheral wall portions of conventional paper boxes. Therefore, even an unskilled person can quickly and easily assemble the paper box.

In addition, since the bottom wall consists of one bottom wall part and each handle part is connected to the bottom wall part via the second peripheral wall part, when carrying the paper box with the items stored therein, There is no possibility that the stored object will fall out. Furthermore, since the paper box itself is provided with a handle, it can be easily carried.

Then, when each of the above-mentioned engagements is released, each part is developed on the same plane. In other words, since the peripheral wall is not made of glue, each peripheral wall can be expanded around the bottom wall. Therefore, even when the stored object is a fragile cake or the like or when the stored object is stored in close contact with the peripheral wall, it is possible to easily take out the stored object. Similarly, objects to be accommodated can be easily accommodated without the surrounding wall getting in the way.

〔Example〕

Hereinafter, the structure of the present invention will be specifically explained based on the embodiments shown in FIGS. 1 to 3.

The assembled paper box 1' of this embodiment is made by assembling paper patterns 1 cut into shapes as shown in FIG. In the explanation regarding FIG. 1, for convenience, the terms "up and down" and "left and right" refer to the top, bottom, left and right in the same figure.

As shown in FIG.
Peripheral wall portions 3a, 3a, rectangular second peripheral wall portions 3b, 3b continuous to the upper and lower edges of the bottom wall portion 2, and a first peripheral wall portion on the left side.
Rectangular first upper wall portions 4a, 4a continuous to the left end edge of the surrounding wall portion 3a and the right end edge of the first surrounding wall portion 3a on the right side
and the small piece-like engaging tongues 5, 5 connected to the left and right edges of each second peripheral wall 4b, the upper edge of the upper second peripheral wall 3b, and the lower edge of the lower second peripheral wall 3b. Continuous U-shaped handle parts 6, 6 with engaging protrusions 6a, 6a formed on the left and right ends, engaging protrusions 7, 7 fitted therein, and left and right edges of each second peripheral wall part 3b. Handle holding parts 8, 8 connected in an inclined manner and each first peripheral wall part 3a
Triangular first folded portions 9, 9 connected to the upper and lower edges of
and rectangular second folded portions 10, 10 continuous to the upper and lower edges of each first upper wall portion 4a, and the boundary between each first peripheral wall portion 3a and the first upper wall portion 4a. Slits 11, 11 are formed in the portions, and engagement holes 8a are formed in each handle portion 8. In addition,
The length of the slit 11 substantially matches the vertical width of the engaging tongue portion 5.

This paper pattern 1 is engraved with folding lines 12 as shown by dashed lines in FIG. That is, these folding lines 12...
On the boundary line between each peripheral wall portion 3a, 3b and the upper wall portion 4
a, 4b, on the boundary line between each second upper wall portion 4b and each engaging tongue portion 5, on the boundary line between each second upper wall portion 4b and handle portion 6, on each second peripheral wall portion 3b. On the boundary line with each handle holding part 8, on the extension line of the boundary line between the second peripheral wall part 3b and the second upper wall part 4b, and on the line that crosses this in each handle holding part 8, on each first peripheral wall part 3a on the boundary line between and each first folding part 9, and each first
On the boundary line between the upper wall portion 4a and each second folded portion 10,
are formed respectively. In addition, each engagement hole 8a is provided in the tip part 8b of the handle holding part 8 so as to be perpendicular to the folding line 12 that crosses the tip part 8b.

Therefore, each part of this paper pattern 1 is folded along each folding line 1.
The paper box 1' is assembled into a paper box 1' as shown in FIG. 2 by folding it along the lines 2 and then engaging a portion of the folded portion.

That is, as shown in FIG.
The peripheral wall portions 3a, 3b are bent to rise from the bottom wall portion 2, and the side ends of the peripheral wall portions 3a, 3b are abutted against each other.
The first upper wall portions 4a and the second upper wall portions 4b are successively folded inwardly to overlap the second upper wall portions 4b, 4b on the first upper wall portions 4a, 4a. At this time, the folded-in portions 9, 10 are folded toward the inner surface of the second peripheral wall portions 3b.

Then, each engaging tongue portion 5 is bent downward and inserted into each slit 11, and the handle portions 6 are bent upward to abut each other. At this time, the engagement protrusion 7 provided protrudingly on one second upper wall part 4b passes through the handle part 6 connected to the other second upper wall part 4b and is superimposed on the second upper wall part 4b. Ru.

Finally, as shown in FIG. 2, each handle holding portion 8 is bent to abut against the outer surface of each first peripheral wall portion 3a, and further, its tip portion 8b is bent toward the handle portion 6 so that the engagement hole 8a is engaged with the abutting engagement protrusions 6a, 6a.

Such assembly does not require complicated engagement operations and requires only a small number of operations, so even an unskilled person can perform it quickly and easily.

Since the bottom wall of the paper box 1' is made up of one bottom wall portion 2, there is no possibility that the stored items will fall out when being carried. Moreover, since the handles 6, 6 are integrally provided on the paper box 1' itself, it is extremely easy to carry the paper box 1'.

Moreover, the assembled paper box 1' has each engaging tongue part 5.
and the engaging protrusion 6a, each slit 11, and the engaging hole 8
When the engagement with a is released, each part can be expanded in all directions around the bottom wall part 2 (see FIG. 3).
Therefore, even when the stored object is a fragile cake or the like or when the stored object is stored in close contact with the peripheral wall, it is possible to easily take out the stored object.

Furthermore, since the paper pattern 1 in the developed form can be immediately assembled into a paper box shape, there is no need for a gluing process as in the case of conventional paper boxes, and the production can be carried out efficiently. Furthermore, since the paper pattern 1 can be stored in the form of paper pattern 1, it is advantageous in terms of storage compared to the conventional case where it is stored in a folded state with glue, such as in a paper box. Of course, it is also advantageous from a sanitary standpoint since no glue is required.

It should be noted that the assembled paper box according to the present invention is not limited to the above-mentioned embodiment, but can be made into various box shapes by changing the shape and dimensions of each part. For example, each second peripheral wall portion 3b can be made into a trapezoidal shape, and the box shape can be made into an inverted trapezoidal columnar shape.

[Effect of idea]

As can be easily understood from the above explanation, the assembled paper box of the present invention has a bottom wall having one bottom wall section, and a handle section connected to the bottom wall section via the peripheral wall section. , the strength of the paper box when being carried can be greatly improved, and the handle allows for easy carrying. In addition, it is possible to assemble and disassemble each engaging tongue and engaging protrusion by engaging and disengaging each slit and engaging hole,
Moreover, since each part can be expanded around the bottom wall part, even an unskilled person can assemble it quickly and easily, and objects to be stored can be easily stored and taken out.
