Description

[Detailed description of the invention] Industrial field of application This invention relates to the structure of a medium boat with vertical partitions, and is intended to save materials for containers.

Conventional technology In general, in a packaging container consisting of an outer box and an inner boat, in order to vertically partition the inside of the inner boat with a width corresponding to the size of the contents, a partition plate with such width is placed on the inner boat. It depended on what I was doing. This will be explained with reference to the accompanying drawings, which are given by way of example.

Figure 5 shows a conventional blank for a medium boat. The base line (folding line) of the inner locking piece 56 is folded into a mountain fold (folding the fold so that it is convex upward is called a mountain fold, and folding it so that the fold is convex downward is called a valley fold. The same applies hereinafter).
The middle boat is completed by valley-folding all the plates and pieces except for this, and pressing the inner piece 57 with the left side plate 55 and the right side plate 55', respectively.

FIG. 6 shows a blank vertical partition plate. A mountain fold is made between the front partition surface 51 and a rear partition surface 51', and the other portion is valley folded, and then it is placed on the bottom plate 53 of the middle boat.

The outer box is for the left half (Fig. 4, 1), as shown by the blank in Fig. 4, Fig. 4, and Fig. 4, 2.
and the outer box for the right half (Fig. 4, 2).
Needless to say, the shape is not limited to this. For these two outer boxes, all the plate pieces were mountain-folded, the pasting piece 39 was glued to the back side of the front plate 31, and the folding piece 37 was completed by pressing the inner piece 38 with the left side plate 36 or the right side plate 36'. Fold it inward to the outer box and it is completed. The lump-like or stick-shaped items to be stored in the container are stored on a partition plate placed on the middle boat, and the outside of the middle boat is covered with an outer box. At this time, the outer locking piece 35 and the inner locking piece 56 will be sandwiched between the outer box and the middle boat, respectively.

Problems to be Solved by the Present Invention By the way, in order to make the vertical partition plate stand upright, it is necessary to have the front bottom plate 50 and the rear bottom plate 50' as a base extending over the middle boat bottom plate 53, which results in waste in terms of materials. many.

Measures to solve the problem Therefore, in this proposal, the vertical partition board itself was abolished and the middle boat itself was given that function, thereby solving the above-mentioned drawbacks. The structure of this proposal will be explained below.

As an example of the middle boat is shown in Figure 1, the bottom plate 1
1, a front plate 10 and a rear plate 12 are arranged in order on the left side, a left side plate 13 and a folding piece 15 are arranged in order on the left side, a right side plate 14 and a folding piece 15 are arranged in order on the right side, and furthermore, a left side plate 13 and a right side plate Inner pieces 16 are arranged at the front and rear of each plate 14, and partition pieces 19 are provided in the bottom plate 11 by cuts 18. As shown in FIGS. 2 and 3, inner locking pieces 17 may be provided in the left side plate 13 and the right side plate 14 by cuts 21, respectively.

This partition piece 19 is a characteristic feature of the present invention. The partition pieces 19 are continuously formed along an imaginary straight line drawn in the length direction of the boat, such as the central axis, by cuts 18 at alternating left and right positions of the line (or axis). The number of rows and the number of partition pieces 19 constituting one row depend on the quality of the articles to be stored.
It may be determined as appropriate, taking into consideration the size, etc. The base of the partition piece 19 can be bent along the crease 20, but in some cases, the second notch 18' may be used to partially form a straight line (FIG. 2) or a curved line to expose the side edge 23. It is also possible to make a cut with (Figure 3, 1) and reduce the portion of the fold 20. The left and right ends of the partition pieces 19 are formed into protruding parts 22 that protrude toward the adjacent partition pieces 19. The shape of the protrusions 22 is not particularly limited, and may be any shape such as a semicircular shape or an acute angle protrusion, as long as they can be mutually locked.

For a medium boat blank having the above-mentioned structure, the inner locking piece 17 is mountain-folded, and all other parts are valley-folded.
When the partition pieces 19 are engaged with each other at the protruding portions 22, the desired middle boat is formed. It is a good idea to store items in this and place them in an outer box.

Function and Effect In this case, since the partition pieces 19 are formed by making cuts alternately on the left and right sides, holes will be made in the bottom plate 11 of the middle boat, but the pressure resistance of the bottom plate 11 will be stronger than when holes are provided only on either the left or right side. We were able to significantly reduce the decline in When the second notch 18' is provided, the area of the fold 20 is reduced, so the restoring force due to bending is alleviated, and the engagement between the two protrusions becomes easier and more secure, and the partition piece 19 It becomes easier to stand upright. Note that when the side edge 23 is provided by the second notch 18', the hole in the bottom plate 11 is naturally smaller than that in the case where the side edge 23 is not provided, so the pressure resistance of the bottom plate 11 is also large, and contents can be accommodated more reliably. There are advantages to this.

In addition to the above-mentioned effects, this project has the effect of reducing the need for two plates, a medium boat and a partition plate, to just one, which not only saves on materials, but also simplifies and improves efficiency in the work process. It became.

Claims (1)

[Scope of utility model registration request] In a packaging container consisting of an outer box and a middle boat, two partition pieces are made by making cuts along an imaginary straight line drawn in the length direction of the middle boat through a part of the bottom plate of the middle boat, at alternate positions on the left and right of that line. A medium boat for a packaging container having inner partitions which are spaced apart from each other and have the ends of the partition pieces projecting to one side of the adjacent partition.
