Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a packaging box that can be divided.

[Conventional technology]

2. Description of the Related Art Conventionally, there are packaging boxes that are made by bending a single punched board, and are sold after being divided into pieces as needed. As shown in FIGS. 9 to 11, this divisible packaging box has opposing side walls 31 and opposing end walls 32 alternately connected via vertical fold lines 33, and other side walls 31. Glue allowance on edge 34
A lid flap 36 is connected to the upper edge of each side wall 31 and each end wall 32 through a horizontal fold line 35, and a lid flap 36 is connected to the lower edge of each side wall 31 through a horizontal fold line 37. The flaps 38 are arranged in a row, and the inner bottom flaps 39 are arranged in a row at the lower edge of each end wall 32 and abut against each other through the transverse fold line 37, and the inner bottom flaps 39 stand up on the abutting edges of the inner bottom flaps 39. Wall 40 and inner end wall 40
A folding piece 41 that is bent in a relative direction from the tip edge and inscribed in the lid flap 36 is extended and connected, and the side wall 31 and the lid flap 36 and outer bottom flap 38 that are connected thereto are connected to each other.
A perforation 42 is provided at the center of each of the two parts to divide the parts into two equal parts.

[Problem that the invention attempts to solve]

However, as shown in FIG.
When the divided small box is divided into two parts using the dividing means 2, the inner end wall 40 of the dividing surface of the divided small box is secured by the folding piece 41, but this is not sufficient and the part is tilted downward. and the inner end wall 4 depending on the weight of the stored items.
0 opened (see the direction of the arrow in FIG. 12), and there was a problem that the stored items would fall out. Furthermore, when inserting an item into this packaging box, the central overlapping inner end wall 40 tends to tilt when the lid flap is open, making it difficult to insert the item.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention has a folding flap that is connected to the edge of the inner end wall and has approximately the same height as the inner end wall, and the folding flap is overlapped with the inner surface of the side wall. It is something.

[Effect]

According to this invention, when the divided small box is divided into two by the dividing means, the inner end wall which becomes the outer wall at the dividing surface of the divided small box is folded in, and the fold-in flap overlaps the inner surface of the side wall, and the upper end thereof touches the lid flap. Since they are in contact with each other, they will not open accidentally.

Further, when inserting an item, the lower end of the folding flap is in contact with the inner bottom flap, thereby preventing the overlapping state end wall in the center from tilting.

〔Example〕

1 to 5 show an embodiment of this invention. The packaging box of this embodiment is made of thick paper such as corrugated cardboard, and has opposing horizontally long side walls 1 and opposing end walls 2 that are slightly shorter than these, which are alternately connected via a vertical fold line 3. A glue allowance 4 is provided continuously at the edge of the end wall 2, and a lid flap 6 is provided at the upper edge of each side wall 1 and each end wall 2 via a horizontal fold line 5.
An outer bottom flap 8 is connected to the lower edge of each side wall 1 through the horizontal fold line 7, and an inner bottom flap 8 is connected to the lower edge of each end wall 2 through the horizontal fold line 7. 9
, an inner end wall 10 which becomes an outer wall after division at the same height as the end wall 2, and a folding piece 11 bent in the relative direction and overlapped with the lid flap 6 are extended and connected, and the side wall 1 and the lid connected thereto are extended. A perforation 12 is formed in the center of the flap 6 and the outer bottom flap 8 to divide the flap into two equal parts, and a perforation 12 is formed at one end edge of the inner end wall 10 at approximately the same height as the perforation and approximately 1 the horizontal dimension of the side wall 1. A rectangular folding flap 13 having a length of /2 is continuously provided.

Further, the folding flap 13 is provided with a small locking protrusion 14 protruding from the center part which becomes the lower edge when assembled and comes into contact with the inner bottom flap 9, and the small protruding piece 14 is provided at the end edge of the inner bottom flap 9 which the folding flap 13 comes into contact with. A small notch 15 into which the projection 14 is inserted is provided to prevent the folding flap 13 from moving. In the center of the free end of the lid flap 6, where the perforation 12 is provided, a semicircular notch 16 for insertion of a fingertip is provided to facilitate opening of the inner end wall 10 of the small box after division.

In this embodiment, perforations 12 are used as dividing means, but cut tape or the like may also be used. Further, if the connecting portion between the inner end wall 10 and the folding flap 13 is perforated, the two can be easily separated, so that the inner end wall 10 can be easily opened after being divided.

This packaging box uses a single die-cut patterned board (see Figure 4) to store items while manufacturing the box. (2) While folding the inner bottom flap 9, the inner end wall 10 is erected, and at the same time the folding flap 13 is inscribed in the side wall 1. (3) The outer bottom flap 8 is folded inward. Assemble the bottom by gluing it to the bottom flap 9, (4) store items from the top opening,
(5) The folding piece 11, each lid flap 6, and both lid flaps that are successively folded and overlapped are glued to complete the sealing.

This packaging box can be easily divided into two parts by separating the perforations 12, and the inner end wall 1 of the dividing surface of the divided small box
0 will not open accidentally due to the function of the folding flap 13 connected thereto, and will not open due to the weight of the stored items even if it is tilted downward.

6 to 8 show other embodiments of this invention. In this embodiment, a folding flap 13 having approximately the same height and approximately half the horizontal dimension of the side wall 1 is provided on one end edge of the inner end wall 10, and a small folding flap 13 is provided on the other end edge. The folding flaps 17 are arranged in series, and when the box is assembled, the folding flaps 13 and 17 are bent in the same direction (see FIG. 7). This embodiment has the advantage that the inner end wall 10 becomes more stable.

〔effect〕

As mentioned above, the packaging box according to this invention has a folding flap connected to the edge of the inner end wall, and when the box is torn into two by the dividing means, the dividing surface of the divided small box is The inner end wall, which has become an outer wall, is stably locked and prevented from coming off via the folding flap connected thereto, and the stored articles will not fall out even if the dividing surface is tilted downward. Further, since there is a fold-in flap, it is possible to prevent the stacked inner end wall from tilting when the lid flap is opened, thereby making it easier to insert items.
