BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging device having a function of cushioning and holding contained articles with corrugated board.

[0002]

2. Description of the Related Art Generally, articles such as electric appliances and other equipment are contained in cardboard packaging boxes for distribution.
A cushioning material is inserted in the packaging box in order to protect the contained articles from impacts during the distribution process.

Styrofoam is often used as the cushioning material, but this styrofoam cannot be recycled, the disposal cost is high, and high heat is generated during incineration, which damages the incinerator. There was a problem in its disposal, such as requiring a large incinerator.

Therefore, various cushioning materials made of corrugated cardboard which can be recycled instead of polystyrene foam have been developed.

[0005]

By the way, in order to cushion the articles to be accommodated by the cushioning material of corrugated cardboard and to hold it stably, a cushioning material composed of a plurality of corrugated cardboards is required, and its manufacture and assembly are not easy. There were difficulties in manufacturing.

The present invention takes note of such conventional problems,
The number of cardboard cushions is small, and its assembly is easy,
Moreover, it is an object of the present invention to provide a packaging device for stably holding and containing contained articles.

[0007]

In order to achieve the above-mentioned object, the present invention is a rectangular parallelepiped and has flaps on four sides of an upper opening, and an outer box made of corrugated cardboard and inserted in the outer box. A buffer holder made of a single cardboard for holding the contained article, and an upper buffer body made of a single cardboard arranged above the accommodated article are provided, wherein the buffer holder is a bottom plate, a side plate, and the side plate. And a corner pad plate that forms a buffer gap between the side plates of the outer box and the side walls of the buffer holder are bent inward and inclined so that the both ends contact the corners of the outer periphery of the contained article. The packaging device is configured as described above.

[0008]

In the above structure, the buffer holder placed in the outer box holds the articles to be housed, but the corner pad of the buffer holder contacts two inner corners of the outer box to position the buffer holder. At the same time, a space is formed between the side plate of the buffer holder and the side plate of the exterior box to protect the contained article from a side impact. Further, both ends of the side plate of the buffer holder are bent so as to incline inward, and since the outer corners of the contained article hit the both ends, it is possible to position the contained article and at the same time with respect to the corners. The shock is alleviated. Furthermore, the upper cushion protects the contained article from impacts from above.
Each of these constituent members is made of corrugated cardboard and has a small number of constituent parts, which is advantageous in terms of recycling and manufacturing.

As shown in FIG. 1, the packaging apparatus of this embodiment has a rectangular parallelepiped outer box 1 made of corrugated cardboard, and a buffer holder 2 made of corrugated cardboard fitted in the outer box 1.
And an upper cushioning body 4 made of corrugated cardboard covering the upper portion of the housed article 3 held by the cushioning holder 2.

The outer box 1 has a flap 5 for sealing on each of the four sides of the upper opening, and two corresponding flaps 5 are provided.
The engagement holes 6 are formed in a and 5b, and the insertion pieces 7 are formed in the other two corresponding flaps 5c and 5d. By inserting the insertion pieces 7 into the engagement holes 6, , Each flap 5 is kept in a sealed state. Also,
When flaps 5c and 5d are folded for sealing, 2
The two leading edges are joined together, and a handle exposed hole is formed by a recess 8 in this joined portion.

2A and 2B are a top view and a perspective view showing a state in which the buffer holder 2 is fitted in the outer box 1 and the article 3 is contained. In this figure, the upper cushion 4 is omitted, and the flap 5 is open. further,
In the present embodiment, the rice-containing rice warmer having a substantially rectangular parallelepiped shape is used as the housed article 3, but the housed article is not limited to the rice-rice warmer.

FIG. 3 is a development view of the buffer holder 2 made of a single cardboard. The buffer holder 2 includes a bottom plate 9 and a bottom plate 9
Two side plates 10 connected to two opposite sides of the bottom plate 9
It is composed of two seat plates 11 connected to the other two opposite sides.

The width a of the bottom plate 9 in the longitudinal direction is about 10 cm shorter than the inner width of the outer box 1 in the longitudinal direction, and the lateral width b of the bottom plate 9 is the same as the inner width of the outer box 1 in the lateral direction. I am sorry.

The side plate 10 has both end portions 12 which are inwardly folded by a ruled line, and a substantially triangular corner contact plate 13 is connected to the tip and the inner end of each end portion 12. Of the corner contact plates 13, the ones on the inner end sides of the both end portions 12 are formed by notches formed in the bottom plate 9 and the seat plate 11.

A projecting piece 14 projecting toward the bottom plate 9 by cutting is formed at a ruled line portion for bending the inner end side corner contact plate 13, and a locking recess 15 is provided near a side part of the seat plate 11. Is forming.

A notch 16 is formed on the front edge of the seat plate 11 by cutting, and a notch hole 17 is formed at a position corresponding to the notch 16 of the bottom plate 9 when the seat plate 11 is folded back. I am doing it. A folding assisted notch 18 is formed in the ruled line portion for folding back the seat plate 11.

The buffer holder 2 is formed as shown in FIGS. 4 and 5 by bending the single cardboard shown in FIG. First, the seat plate 11 is folded back so that it overlaps with the back side of the bottom plate 9 at the ruled line portion at the boundary with the bottom plate 9. Then, the locking piece 16 on the front edge of the seat plate 11 is bent upward to lock the locking hole 11 of the bottom plate 9.
To fix the bent state of the seat plate 11 (FIG. 5).

Next, the side plate 10 is bent upward with respect to the bottom plate 9 along its ruled line and at a right angle. Then, each corner contact piece 13 is bent horizontally so as to project outward. Further, both ends 12 of the side plate 10 are bent inward at about 45 °. At this time, due to the bending of the corner contact piece 13 on the inner end side, the protruding piece 14 protruding downward fits into the locking recess 15 on the side portion of the seat plate 11 to fix the bent state of both end portions 12. . The buffer holder 2 thus formed as shown in FIG. 4 is fitted into the outer box 1 as shown in FIG. At this time, the two sides of each corner contact plate 13 come into contact with the upper and lower two side plates of each corner portion inside the outer box 1, and both end portions 12 of the side plate 10 are oblique with respect to the corner portion of the outer box 1. Thus, the leading edge contacts the inside of the outer box 1, and the buffer holder 2 in the outer box 1 is positioned and stabilized. And
The seat plate 11 holds the bottom plate 9 of the buffer holder 2 in a floating state with respect to the inner bottom of the outer box 1 (FIGS. 9 and 10), and
The length of the bottom plate 9 in the buffer holder 2 in the longitudinal direction is set to be considerably shorter than the length of the outer box 1 in the longitudinal direction, and the respective corner contact plates 13 serve as spacers to serve as side plates of the outer box 1 and the buffer holder. A sufficient buffer gap is obtained between the two side plates 10.

In this state, as shown in FIG. 2, the rectangular parallelepiped accommodation article 3 is put into the buffer holder 2, but the lateral width of the accommodation article 3 is made slightly smaller than the lateral width of the bottom plate 11 of the buffer holder 2. As a result, the corners of the outer periphery of the housed article 3 come into contact with the substantially central portions of the surfaces of the end portions 12 of the side plate 10 that is inclined. Therefore, a buffer gap is secured between the side surface of the housed article 3 and the inner side surface of the exterior box 1. As described above, when the contained article 3 is held by the buffer holder 2, the buffer gap exists in the lower portion and the entire outer circumference, and the buffered article 3 is sufficiently buffered.

FIG. 6 is a development view of the upper cushioning member 4 made of a single cardboard. The upper shock absorber 4 is composed of a rectangular holding plate 19 as shown in the figure, and two contact plates 20 connected to opposite sides of the holding plate 19. Here, the width C in the longitudinal direction of the holding plate 19 is made larger than the width in the lateral direction of the outer box 1, and the width d in the short direction of the holding plate 19 is in the longitudinal direction of the bottom plate 9 of the buffer holder 2. Is almost equal to the width a. The pressing plate 19 is parallel to the short direction and has two ruled lines at equal intervals, and the corner portions are also ruled to form four triangular corner pieces 21.

As shown in FIG. 7, the holding plate 19 is folded into a trapezoidal shape with two ruled lines, and the backing plate 20 and the corner piece 21 are bent upward to stand upright. By fitting the upper cushioning body 4 on the upper portion of the cushioning holder 2, the central portion of the trapezoidal holding plate 19 as shown in FIG. The part hits the upper corner of the housed article 3 and is inserted between the side part of the housed article 3 and the side plate of the outer box 1. Then, the contact plate 20 comes into surface contact with the side plate of the outer box 1, and the corner pieces 21 come into surface contact with both inclined end portions 12 of the side plate 10 of the buffer holder 2 to stabilize the upper buffer body 4. As described above, since the inclined both sides of the trapezoidal holding plate 19 press the upper corners of the housed article 3, the impact from above the housed article 3 is buffered.

As shown in FIG. 7, a strip-shaped handle 22 which is long in the width d direction is attached to the central portion of the holding plate 19 of the buffer body 4. This handle 22 has stopper seats 2 at both ends.
3, the stopper seat 23 is passed through two guide holes 24 formed in the central portion of the pressing plate 19, and the end of the handle 22 is slid into a cut groove 25 connected to the guide hole 24 to be fixed. .

After mounting the above-mentioned upper shock absorber 4, FIG.
Close each flap 5 of the outer box 1 as shown in Fig.
Is inserted into the engaging hole 6 to fix each flap 5 and complete the packaging. At this time, a strip-shaped handle 2 is formed from the handle-exposing hole formed by the recess 8 formed at the tips of the flaps 5c and 5d.
2 is exposed, and this handle 22 can be carried around. Since the upper cushioning body 4 is in contact with the flap 5 on its surface, the load is not locally applied, and the end portion to which the handle 22 is fixed is less likely to be damaged.

As described above, the packaging apparatus of this embodiment is accommodated by the buffer holder formed by bending one corrugated board and the upper buffer formed by bending one corrugated board. The article can stably and surely hold the buffer, the number of the buffer bodies is small, and the assembly is easy.

In addition, in the embodiment, since the article to be housed has a rectangular parallelepiped shape, the outer box and the buffer holder have a rectangular parallelepiped shape to which they are applicable, but the present invention is not limited to this. If the contained article is a square, the outer box, the buffer holder, and the upper buffer may be shaped accordingly. Further, the seat plate connected to the bottom plate may be omitted.

[0026]

As is clear from the description of the above embodiment,
The present invention has a structure in which a buffer holder constituted by bending a piece of cardboard is inserted into an outer box, and the buffer holder holds an article to be housed. A buffer gap is formed between the side plate and the side plate of the buffer holder, and both ends of the side plate of the buffer holder are tilted and applied to each corner of the outer periphery of the stored article to position the stored article and buffer the corner. Since it is performed, the contained article is stably held and sufficient cushioning is obtained.

Further, an upper shock absorber made of a piece of corrugated board fitted to the upper part of the shock absorber holder is provided, and the holding plate of the upper shock absorber is bent and inclined at both sides so as to have a trapezoidal shape. Since the corners of the upper part of the contained article hit both sides, the shock from above is buffered, and the pressing plate and the corner plate are further provided to stabilize the mounting state of the upper buffer.

As described above, the packaging apparatus of the present invention is capable of buffering and holding contained articles without using styrofoam and using a small number of cushioning bodies made of corrugated cardboard, and its value is great.
