Description

[Detailed description of the invention] <Industrial field of application> The present invention is designed to provide a barrier between each corner of a product placement surface that covers the bottom of the product and an adjacent side surface that stands upright on the periphery of this product placement surface. This invention relates to a packaging container in which corner cushioning material is temporarily fixed to each corner.

<Prior Art> Conventionally, as disclosed in Japanese Utility Model Publication No. 55-56154, as a packaging container of this type, a corner portion of an inner flap constituting a product placement surface of a box-shaped container has been used. By providing fold lines parallel to each side surface at appropriate intervals from the adjacent side surfaces, and providing cut lines in a planar U-shape from both ends of these fold lines toward each side surface, a pair of upright pieces can be formed. There is a structure in which the corner cushioning material is formed so as to be bendable, and the corner cushioning material is pressed against the adjacent side surface by the restoring force of these two upright pieces, and is temporarily fixed.

<Problems to be solved by the invention> However, in such conventional packaging containers, the bottom plate of the container is laminated and fixed below the inner flap where the upright piece is formed when the container is assembled. However, after the container is assembled, the upright piece cannot be pushed up from below the inner flap, making it difficult to raise the upright piece, which makes the work time consuming.

In view of such conventional circumstances, the present invention has been proposed to allow a finger or the like to be inserted around the upright piece from above, and to make it easy to raise the upright piece even after the container is assembled by forming the upright piece on the inner flap of the box-shaped container. With the goal.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to create fold lines parallel to each side surface at appropriate intervals from both sides adjacent to each corner part. A cut line is provided from the corner of this fold line toward the corner of the product placement surface, and a cut line is provided from the tip of the score line to both ends of the fold line. A pair of upright pieces are formed so as to be bendable, and an insertion hole is drilled through the joint between the two cut lines and the cut line.

<Function> The function of the present invention is to bend and stand up the upright piece along the crease line by inserting a finger or the like from above into the insertion hole of each corner and pulling up the tip of the upright piece. .

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

In this embodiment, as shown in Fig. 1, the packaging container is a packaging tray, and in the figure, 1A is the original plate forming the tray body A, which is cut out to a desired length using cardboard or the like. are doing. This original plate 1A
It is composed of a central bottom plate 2 that constitutes a product placement surface, and side plates 1 surrounding the bottom plate 2.

The bottom plate 2 has a rectangular shape from the front, and has upright pieces 3 formed at its four corners 8 and at the center of its longitudinal periphery.

The side plate 1 is continuous from the periphery of the bottom plate 2 via a fold line 1c, and on both end faces of the side plate 1a in the longitudinal direction, there are folding pieces 7 that are fixed to the inner surface of the side plate 1b in the transverse direction when folded. They are formed in a continuous manner via 7a.

Upright pieces 3 formed at corner portions 8 of the bottom plate 1
... is provided with fold lines 3a, 3a parallel to each side plate 1b, 1a at right angles to the plane at appropriate intervals from the side plates 1b, 1a adjacent to each corner part 8, and from the corner of the fold lines 3a, 3a to the bottom plate. A score line 3b is provided toward the corner of 1, and a score line 3c is provided from the tip of the score line 3b to both ends of the crease lines 3a, 3a.
3c, respectively, to form a pair, and an insertion hole 4a is drilled through the joint between the cut lines 3c and the cut line 3b.

A fold line 3d parallel to the side plate 1a that faces the upstanding pieces 3a formed at the center of the longitudinal periphery of the bottom plate 1, and a fold line 3d parallel to the side plate 1a from both ends of the fold line 3d.
Fold lines 3e, 3e extending at right angles to the direction, cut lines 3g, 3g extending obliquely from the corners of the fold lines 3d, 3e, 3e, respectively, and both ends of the fold lines 3e, 3e. Three pieces are formed by a cut line 3g and a cut line 3f through which the tip of the cut line 3g passes in the middle, and an insertion hole 9a is drilled through the joint between both cut lines 3g and 3g and the cut line 3f. are doing.

The corner cushioning material 4... and the center cushioning material 9... are folded along the fold lines 3a, 3a and the fold line 3 from each side surface 1b, 1a.
It is made of cardboard, styrofoam, etc. and has approximately the same dimensions as the dimensions up to d, 3e, and 3e, and is placed at the top to prevent product B from moving or wobbling when it receives the bottom part 1B of product B placed above. A fitting notch 10 is formed therein.

Then, by inserting a finger or a tool, etc. into each insertion hole 4a...9a... from above, or by pushing up from below, each upright piece 3... is erected, and then the corner cushioning material 4... and the center cushioning material 9... Insert and fit them respectively.

At this time, the upright pieces 3... are respectively opposed to the side plates 1.
Since it is bent from the a and 1b sides, that is, from the outer side, its restoring force is applied to the corner and central cushioning materials 4...9.
... acts in the direction of pressing the side plates 1a, 1b, and firmly temporarily fixes the cushioning materials 4, 9.

Then, the product B is loaded from above, and the tray body A is further placed upside down on top of the product B, and the outer box 11 is inserted from above, and then tied with cable ties 12 for packaging and transportation. do.

Incidentally, if the product B is small-sized, the upright piece 3 at the center of the longitudinal circumferential end of the bottom plate 2 is intentionally unnecessary.

<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

By inserting a finger etc. from above into the insertion hole of each corner part and pulling up the tip of the upright piece,
Since the upright piece is bent along the fold line to stand up, the upright piece is formed on the inner flap of the box-shaped container, and even after the container is assembled, the upright piece can be easily raised, making the work less time-consuming. do not have.
