Description

[Detailed Description of the Invention] The present invention relates to a packaging corner part for collectively packaging a plurality of products of the same shape in a continuous manner.

Conventionally, when shipping products, it has been necessary to respond flexibly to shipping quantities depending on customer and market demands, factory production conditions, etc. Therefore, in packaging as well, it is essential to take reasonable measures for packaging shapes that can accommodate any number of items to be packaged. Therefore, when group packaging multiple products of the same shape using corner parts, if the corner parts have the same common shape, the wall thickness sandwiched between adjacent items to be packaged will overlap, making it difficult to package a single product. As a means to avoid this problem, a continuous corner part is often used in which the thick part is shared between the parts. However, this type of continuous corner part is generally made by laminating integral parts according to the number of package contents, or by molding with injection molding.
For example, if there are three articles, three continuum corner parts are used, and if there are five articles, five continuum corner parts are separately molded and used.
However, the above-mentioned continuous corner parts have to be prepared in a variety of types depending on the number of shipments, are large in size, significantly increase manufacturing costs, and are bulky to manage when not in use. This method requires a lot of time and effort, and has various drawbacks, such as loss of use if the number of packages does not match.

The present invention was developed in view of the above points, and by continuously combining and joining two types of regular shapes, corner parts corresponding to the quantity of package contents can be assembled and molded, thereby greatly reducing manufacturing costs. The present invention proposes a packaging corner part which is reduced in width, extremely convenient to manage when not in use, and completely eliminates usage loss.

The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is a perspective view showing the smallest basic combination unit of the corner putt of the present invention, and the basic combination unit is hereinafter referred to as one corner putt. Here, contents 1
When packaging the stand, four corner pieces are used because they are attached to each square of the contents.

As shown in Fig. 1, one corner part consists of one central part 1 located in the center and one central part 1.
It is composed of two side parts 2 on both sides sandwiching it, and one corner part 10 is formed in the center. This central part 1 and side part 2
Common parts with two types of regular shapes are constructed depending on the shape. As shown in the developed view of FIG. 2, the central part 1 is formed into a flat plate, bent at the center, and assembled with the side parts 2.

Here, the central part 1 is provided with a cut groove 5 for bending in the center. This groove 5 is stopped in the middle by providing an appropriate uncut piece 6 according to the characteristics of the material that provides the bending hinge part. Next, protrusions 7, 7 are provided on both end faces to be connected to the side part 2 for connection to the side part 2. It is desirable that the number of the protrusions 7, 7 be two or more for one bonding side.

Next, the side part 2 has a triangular shape as shown in FIG. 3, and recesses 8, 8 are formed in the position where the convex part 7 of the central part 1 bent into an L shape is fitted. Here, a feature is that the protruding length t/2 of the convex part 7 of the central part 1 is half the depth t of the concave part 8 of the side part 2. This is to leave enough depth for the next adjacent convex portion 7 of the central part 1 to be fitted when constructing the continuous type. Furthermore, the central part 1 and the side parts 2 are each formed with the same thickness t. Two convex portions 7 provided on both side surfaces of the central component 1 are formed with a predetermined gap 6 in the center and the same width a. Furthermore, the protruding widths c and c at both ends of the central part 1 are
Each is formed with the same width. The concave portions 8 of the side part 2 correspond to the convex portions 7, and are formed to have the same width a with gaps b at corresponding locations so that they fit properly. The protruding width c of the ends is also the same as that of the central part 1, so that when connected, each end becomes flush, improving the appearance.

Next, the mechanism of the assembled configuration will be explained based on the assembled perspective view of FIG. Bend the other center part 1 into an L-shape on the right corner part of Fig. 4 and side part 2.
into any one of the The other side parts 2 are then inserted into the central part 1. By successively inserting and assembling other central parts 1 and side parts 2 in this order, any combination of continuous corner parts can be formed.

FIG. 5 shows an example of a completed three-corner continuous body, and FIG. 6 shows an example of cardboard packaging using the three-corner continuous body shown in FIG. 5. A 3-corner continuous body is attached to three packaged body models 3, 3, and these are housed in a packaging container 4.

Here, a specific example of the manufacturing method of the present invention will be described. The following manufacturing method can be considered for the basic parts of the central part 1 and the side parts 2 shown in FIGS. 2 and 3.
Firstly, when using a cushioning material such as an extrusion molded product or a flat material such as cardboard, one-piece cutting is performed using a press, and secondly, when using a foam molded product raw material or a thermoplastic raw material, an in-die excision is performed. There is mold molding processing, etc.

As described above, according to the continuous packaging corner part of the present invention, it is possible to produce corner packaging that corresponds to the quantity of all package contents by manufacturing two types of regular small parts, so it is possible to produce small quantity and large quantities of products. This has the effect of suppressing the increase in manufacturing costs, which was a drawback of conventional products, and significantly reducing manufacturing costs. Moreover, inventory management can be done with small parts, which significantly reduces management costs.Furthermore, by making it possible to use an appropriate number of parts and eliminating usage losses, total costs can be significantly reduced. This has the effect of achieving
