Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a packaging box that allows easy loading and unloading of products, particularly a packaging box that can also be used for display purposes.

[Prior Art] For example, there is a packaging box shown in FIG. 6 that allows easy loading and unloading of products.

In this packaging box, a rear wall a, a bottom wall b, a front wall c, and a top wall d are successively connected along a fold line to form a rectangular cylindrical body that can be expanded. A side wall e is connected to the edge of the bottom wall b, and the rear edge of the side wall e is connected to the rear wall a via a gluing margin _e1 . Also, the front wall c
A triangular corner wall f is connected to both end edges of the . Its upper edge is connected to the top wall d via a glue f ₁ .

Therefore, when the box is opened, the top and front parts are open as shown in the figure, making it easy to put in and take out products.Moreover, the products can be clearly seen, so they can be used for display.

[The problem that the idea attempts to solve]

By the way, regarding the packaging box with the above structure,
Since the side wall e and the corner wall f must be glued to the rear wall a and the front wall d, respectively, it takes time and effort to assemble them. Furthermore, for the reasons described above, if a plurality of boxes are assembled in advance, the boxes themselves will become bulky, making it difficult to store them.

Furthermore, since this type of packaging box is assembled by gluing as mentioned above, the shape cannot be changed freely, and a part of it cannot be used as a display board for advertising. It's also difficult.

Therefore, the problem with this invention is that it can be easily assembled without using adhesives, and when displaying products, by changing the shape of the box, a part of the box can be used as a display board for advertising. The goal is to improve this type of packaging box so that it can be used.

[Means to solve the problem]

In order to solve the above problems, the packaging box of this invention has an expandable body in which a rear wall 11, a bottom wall 12, a front wall 13, and a top wall 14 are sequentially connected via fold lines 31, 32, and 33. A triangular corner wall 22 is formed at both ends of the bottom wall 12 via a fold line 42.
The rear edge of this corner wall 22 and the rear wall 1
1 by a connecting piece 21 that is folded in half at a diagonal fold line 51 starting from the end of the fold line 31, and the connecting piece 21 is folded in half and attached to the inner surface of the rear wall 11. A presser plate 11a is pressed and stacked on the upper edge of the rear wall 11 via a fold line 34, and
A fixing plate 22a that is folded inward and whose rear edge presses and fixes the end of the presser plate 11a is connected to the inclined edge of the corner wall 22 via a fold line 52, and the fixing plate 22a is connected to the upper wall 14 side walls 24 on both ends of the
are connected to each other via a fold line 44, and the front edge of the side wall 24 and the edge of the front wall 13 are connected inward by a diagonal fold line 53 starting from the upper end of the front wall 13. They are connected by a connecting piece 23 that is folded in half, and the presser plate 11 is attached to the rear edge of the upper wall 14.
The folded piece 14a that is superimposed on a is the fold line 3.
A configuration in which they are connected via 5 was adopted.

[Effect]

In the packaging box configured as described above, in the assembled state, the connecting piece 23 which is folded in half prevents the side wall 24 from falling inward, and
The two-folded connecting piece 21 is pressed against the rear wall 11 by the presser plate 11a, so that the rear wall 11 and the corner wall 22 are maintained in an upright state.

Furthermore, after opening the packaging box in which the product is packaged, the folded connecting piece 23 is unfolded, and the side wall 24 and the top wall 14 are folded over the inner surface of the connecting piece 23 and the front wall 13. Replace the packaging box with the rear wall 11 at the bottom. Then, the top wall 14 and side wall 24 stand up and can be used as a display board for product advertisement.

〔Example〕

Examples will be described below with reference to the drawings.

The packaging box shown in FIGS. 1 and 2 is assembled from a blank, as shown in FIG. 5, made of cardboard or other cardboard.

As shown in the figure, the rear wall 11, the bottom wall 12, the front wall 13, and the top wall 14 are arranged at fold lines 31, 32, 33.
are successively connected to each other via , thereby forming an expandable trunk.

A triangular corner wall 22 is connected to both ends of the bottom wall 12 via a fold line 42, and the rear edge of the corner wall 22 and the end edge of the rear wall 11 are
They are connected by a connecting piece 21 that is folded in half along a diagonal fold line 51 starting from the end of the lower edge of the rear wall 11 .

Further, on the upper edge of the rear wall 11, a presser plate 11a that presses down the connecting piece 21 folded in half on the inner surface of the rear wall 11 is continuously provided via a fold line 34. Further, a fixing plate 22a is connected to the inclined edge of the corner wall 22 via a fold line 52, and its rear edge presses and fixes the end of the presser plate 11a when folded inward. . Furthermore, bent pieces 22b and 11b are connected to the lower edges of the fixed plate 22a and the presser plate 11a through fold lines 47 and 36, respectively.

A side wall 24 is connected to both ends of the upper wall 14 via a fold line 44, and the front edge of the side wall 24 and the end edge of the front wall 13 are connected to the upper end edge of the front wall 13. They are connected by a connecting piece 23 that is folded in half along a diagonal fold line 53 starting from the section. Further, on the rear edge of the upper wall 14, a bent piece 14a which is overlapped with the presser plate 11a when forming the trunk is continuously provided via a fold line 35.

Note that a tongue piece 11d is formed on the rear wall 11 and the presser plate 11a, and is cantilevered on the rear wall 11 by a parallel cut 11c that crosses the fold line 34 at right angles and whose ends are connected to each other within the presser plate 11a. There is. Further, on the fold line 35, the tongue piece 11
A slit 14b is provided for inserting the tip of d.

The blank configured as above is first
As shown in the figure, the connecting piece 21 is folded in half along the fold line 51 to make the rear wall 11 and the corner wall 22 stand up. Next, the holding plate 11a is bent inward along the fold line 34, and the connecting piece 21 is attached to the rear wall 1.

When the fixing plates 22a are superposed one on top of the other, the rear edge of the fixing plate 22a comes into contact with the end of the presser plate 11a, and the bent state of each other is maintained. At this time, as shown in FIG. 4, the bent piece 22b is bent at the corner part.
By overlapping the folded piece 11b under the folded piece 11b, its shape retention is further improved.

In this state, the product is placed on the bottom wall 12, and the connecting piece 23 is folded in half to make the side wall 24 and the top wall 14 stand up from the front wall 13, as shown in FIG. Then, as shown in FIG. 3, with the side wall 24 inserted inside the corner wall 22, the folded piece 14a is stacked on the inside of the presser plate 11a, and the tongue piece 11d is inserted into the slit 14b to complete the packaging.

When opening the packaging box in which the product is packaged in this manner and displaying the product at a store, first, the connecting piece 23 and the side wall 24 are expanded. Next, the top wall 14 and the side walls 24 are folded over the front wall 13 and the connecting piece 23.

Then, as shown in FIG. 4, when the box is repositioned so that the rear wall 11 is at the bottom, the top wall 14 and side walls 24 will be in an upright state, so the top wall 14 and side walls 24 will be placed in an upright position. It can be used as a display board.

Note that, at this time, if the bent piece 14a is inserted under the bent piece 22b, the support stability of the display board will be increased.

In this way, the bent pieces 11b and 22b are useful not only for improving the shape retention of the rear wall 11 and the corner wall 22, but also for improving the support stability of the display board, but are not necessarily necessary. For example, when the packaging box is made of thin corrugated cardboard, a protrusion and a slit that engages with the protrusion may be provided in place of the bent pieces 11b, 22b.
