Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a packaging box that allows items to be easily taken out when opened and that can be transformed into a display stand.

[Conventional technology]

Conventionally, for example, when packaging cameras and small electrical appliances, large packaging boxes are often used and cushioning material is used around them in order to protect the stored items and make them easier to take out. A packaging box is known in which a part of the side wall can be cut out along a perforation or folded back along a fold line to be used as a display stand for displaying removed items.

[Problem that the invention aims to solve] However, today, as transportation conditions have improved, there is a demand for lighter packaging, more efficient transportation, and ease of packing and unpacking. They have disadvantages such as requiring a large amount of packaging materials, having a relatively complex structure, requiring time to pack and take out the box, and requiring considerable effort to transform into a display stand.

This idea was made in view of these problems, and its purpose is to bend and form a single punched board, and use it to package items in boxes.
To provide a packaging box that is easy to take out and can be transformed into a sturdy display stand.

[Means to solve the problem]

In order to achieve the above object, the packaging box in this invention has a pair of side walls and a pair of end walls connected around the bottom wall, a lid flap connected to the edge of one side wall, and a lid flap connected to the edge of the other side wall. An inner wall that is folded inward, an inner bottom wall, and a connecting wall with an adhesive margin for adhering to the lid flap are successively installed on the edge of the flap, and a center fold line is provided on the lid flap, and a gap is formed on the edge of the flap. The lid flap is provided with a protruding piece, and a slit for inserting the insertion piece is provided on the bottom wall.The lid flap is folded over the outer surface of the box body, and the insertion piece of the lid flap is inserted and locked into the slit on the bottom wall for display. It can be transformed into a stand.

[Effect]

In a packaging box constructed in this way, the inner bottom wall is fixed to the middle of the lid flap via a connecting wall, so when the lid flap is opened, the product is lifted up along with the inner bottom wall. It becomes easier to take out items.

In addition, in stores, by folding the lid flap over the outside of the box and inserting and locking the insert into the slit in the bottom wall, it becomes a stylish display stand with the middle bottom wall raised, and it also has a load-bearing capacity. Even if the item is heavy, the bottom wall will not fall down.

〔Example〕

An embodiment of this invention will be described based on the accompanying drawings. As shown in FIG. 1, this packaging box has a middle bottom wall 12 connected to the middle of a lid flap 5 that closes the upper opening of the box, and when the lid flap 5 is raised, the middle bottom wall 12 is attached. It is assembled from a punched board made of cardboard or other thick paper, as shown in Figure 2.

The punched board has paired side walls 2 on the four sides of a rectangular bottom wall 1.
A lid flap 5 of approximately the same size as the bottom wall 1 is connected to the edge of one side wall 2 via two fold lines 4, and a lid flap 5 of approximately the same size as the bottom wall 1 is connected to the edge of the other side wall 2. An inner wall 9 is connected to the edge through a central slit 7 and two fold lines 8 at both ends, and a tongue piece smaller than the bottom wall 1 and at the center of the end is attached to the edge of the inner wall 9 via a fold line 10. A middle bottom wall 12 having a diameter of 11 is connected in a row, and the side wall 2 has approximately the same size as the side wall 2 which has a glue allowance 16 at the free end through the fold line 13 at both ends located at the base of the tongue piece 11 on the edge of the middle bottom wall. An inner end wall 19 having a small protruding edge 18 at the free end is connected to the end edge of both end walls 3 via two fold lines 17, and a corner of the side wall 2 and end wall 3 is connected to each other. A folding wall 21 having a diagonal center fold line 20 of 45° is continuously provided at the portion.

Further, an insertion piece 6 is provided protruding from the center of the free edge of the lid flap 5, and a U-shaped slit 15 is provided along the tongue piece 11 between the middle bottom wall 12 and the connecting wall 14, so that the lid flap 5 has a distance m from the broken line 4 (side wall 2
A center folding line 24 for forming an exhibition stand is provided along the height m).

Assuming that the distance from the center fold line 24 of the lid flap 5 to the free end is l, the bottom wall 1 has a slit 22 for inserting the insertion piece 6 at a distance l from the side wall 2 continuous to the lid flap 5 and along this. A slit 23 for inserting the small protruding edge 18 is provided at the boundary with the end wall 3.

Fold the folding wall 21 in half from the center fold line 20 and insert it between the end wall 3 and the inner end wall 19, and make the slit 23.
When the projecting edge 18 of the inner end wall 19 folded inward is inserted, a stable upper part is assembled into a box with an open double peripheral wall.

The connecting wall 14 is joined to the middle of the back surface of the lid flap 5 (see FIGS. 1 and 3) via a glue margin 16 so as to be substantially parallel to the side wall 2 during sealing. Furthermore, the connecting wall 14 is provided with a center fold line 25.
From there, it is folded in half (see Figure 1).

When the lid flap 5 is bent backwards when transformed into an exhibition stand (see Fig. 4) and overlapped with the outer surface of the box body, the insert piece 6 can be inserted into the slit 22 of the bottom wall 1. .

As shown in FIG. 1, in this packaging box, when the opened lid flap 5 is tilted back approximately 45 degrees, the connecting wall 14 and the middle bottom wall 12 are lifted up and the slope along the lid flap 5 is lifted. It forms a display stand, on which the item A taken out can be displayed diagonally.

On the other hand, the lid flap 5 is provided with two mid-fold lines 26 that are offset from the mid-fold line 24 toward the fold line 4, and when the lid flap 5 is bent forward from the mid-fold line 26 (see Fig. 5), Adjacent center fold line 2
4, the lid flap 5 is bent into a mountain shape, and an insert piece 6 is inserted into the U-shaped slit 15 to allow the lid flap 5 to be transformed into another display form.

A case in which the packaging box of this invention is used will be explained. First, when packaging an item, the upper opening is closed with the lid flap 5 and the insert piece 6 is inserted into the slit 7 at the upper end of the side wall 2 to seal the item, as shown in FIG.

Next, as a first usage example when used as a display stand in a store, as shown in FIG. When stopped, the V-shaped cross section formed by the sloped middle bottom wall 12 from which the tongue piece 11 projects upward and the sloped inner wall 9 connected thereto becomes a stable place for storing items. In this form, even if the item is heavy, the insertion piece 6 is locked to the bottom wall, so there is no risk of the middle bottom wall 12 falling.

Please note that when repackaging this packaging box after display, please use the bottom wall 1.
and the bent lid flap 5 (first usage example), and the middle bottom wall 12 and the bent lid flap 5 (second usage example) are disengaged, and the product is placed and the middle bottom wall 12 is moved downward. It is preferable to press down and insert the insert piece 6 into the middle slit 7.

[Effect of idea]

This idea is structured as described above, so
This produces the following effects.

It is made by bending a punched board made of a thick plate such as cardboard, and it does not require a separate cushioning material and can be provided at a relatively low cost.The inner bottom wall lifts up as the lid flap is opened. This makes it easy to take out items.

At a store, if the lid flap is later folded down and overlapped with the outer surface of the box body and bent to form a display stand, the lid flap will be locked to the bottom wall via the insertion piece at the free end, so it will not be durable. It becomes an exhibition stand with excellent loadability, can be transformed into a stable exhibition stand even when items are heavy, and can be easily resealed.
