Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging device for an outdoor unit of a wooden single-piece air conditioner, etc., which is an industrial field of application.

Conventional configurations and their problems Generally speaking, among packaging devices used for packaging goods, such as the outdoor unit of a separate air conditioner,
Resource-saving packaging equipment is used.

As shown in Fig. 3, this resource-saving packaging device stores 1. A lower cushioning material is also provided, which is made of corrugated paper, wood, etc., and is made by bonding a cushioning material that supports the article and protects it from external forces.
Place the goods to be packaged in the lower part of this a-shock material aKIO. Furthermore, pillars c1, c2, c3, and c4 are erected at each corner of this lower cushioning material a to provide support during storage, and the outer parts of the goods to be packaged are placed in a box d and the cushioning material. Incorporate the upper cushioning material 1, which is made of corrugated paper in the same way as the lower cushioning material d and has a cushioning material adhered inside it, which supports the goods and buffers it from external forces. g
It was to be tied and packaged. However, with this shaped packaging device, the upper FGB relaxation phase f is as shown in Figure 4.
It is necessary to throw one piece of B new material to support and protect the goods into the inner box 11111 formed in the shape of a tray.
This processing work becomes essential. Furthermore, when handling goods during the logistics process, the rising part i of the tray-shaped outer box of the L part cushioning material f and the band g are used as handles.
In particular, it is necessary to designate the handle part, and by folding the corrugated paper on the rising edge of the outer box that forms the handle twice, it is made thicker so that it can be easily grasped, and the end surface of the corrugated paper is Therefore, care must be taken to avoid injury during cargo handling work. In addition, reinforcing tape or the like is attached to the corrugated cardboard to prevent the corner k of the upper cushioning material f from tearing when the handle i is held and pulled in the X direction during cargo handling. There were drawbacks such as an increase in the number of parts required, poor workability, increased costs, and poor workability when handling cargo.

OBJECT OF THE INVENTION Therefore, the present invention aims to eliminate such conventional drawbacks.
To provide a packaging device that can be obtained at low cost by reducing the amount of materials used for packaging, has excellent workability, and can handle cargo safely and efficiently during the logistics process.

Composition of the Invention The present invention consists of forming a hollow prismatic side wall by alternately folding two opposite sides of the four-sided rising portion of the upper cushioning material inward, and inserting a plate-like top plate into the inside surrounded by the side wall. By doing so, by fixing the hollow prismatic side wall and configuring the upper cushioning material, it is possible to provide the function of supporting the article to be packed and buffering against external force, and furthermore, it is possible to form the handle portion at the same time. This facilitates the processing of the packaging material, reduces the number of parts, and provides a packaging device that can be manufactured at low cost and has excellent workability during cargo handling.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In Fig. 1, 1 is an outer box made of corrugated paper in the shape of a tray, with rising parts 2, 3, 4, and 5 on the four sides extended, and several square holes in the rising parts 4 and 5 in the longitudinal direction. 6 to form cast portions 7 at the tips of both ends. The eight top plates are also made of corrugated paper, and protrusions 9 are provided on the end faces in the longitudinal direction at the same intervals as the square holes 6 provided in the rising parts 4 and 5 of the outer box 1. Therefore, the two opposite sides 2, 3 and 4, 5 of the outer box 1 are alternately folded inward to form a hollow prismatic portion 10 as shown in detail in FIG.

At this time, when the end faces of the cut portions 7 provided in the upright portions 4 and 5 come into contact with the inner walls of the upright portions 2 and 3, the rebound of the corrugated paperboard in the upright portions 2 and 30 is suppressed. Furthermore, the top plate 8 is pushed into the inside formed by the rising parts 2, 3, 4, and 5 of the outer box 1, and the square hole 6 provided in the rising parts 4 and 5 and the convex part provided in the top plate 8 are inserted. By interlocking with 9, the repulsion of the corrugated paper of the rising parts 4 and 5 is suppressed by the top plate 8, thereby forming an upper cushioning material. A product packed using this new upper PJ material and using the same packaging procedure as before supports the article 11 with the hollow prismatic section 10 formed inside the cushioning material, and at the same time buffers against external forces. This hollow prismatic portion 10 serves as a handle when handling cargo, allowing stable transportation.

As mentioned above, in this packaging device, the rising part of the tray-shaped outer box is folded into the inner 1111U into a hollow prismatic shape, thereby greatly reducing the number of parts that make up the cushioning material.
It can be produced at low cost and has extremely good workability. or,
The handle has a prismatic shape, allowing for reliable cargo handling, preventing accidents, and reducing the burden on workers. Since the article is supported by the entire circumference of the inner wall of the cushioning material, it has divine advantages such as high reliability in protecting the article.

Effects of the Invention As is clear from the above embodiments, the present invention involves folding the rising portions of a tray-shaped outer box into a hollow prismatic shape, and fixing the raised portions together by tensioning the top plate. This reduces the number of parts and eliminates the need for fixing parts such as adhesives, which improves workability. In addition, this packaging device can handle cargo safely and efficiently during the logistics process.
