DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention includes a body and a glove.
It relates to a packaging device for accommodating a non-lighting fixtures in cardboard outer box inside.

[0002]

2. Description of the Related Art Conventional packaging devices for packaging lighting equipment and the like are disclosed in, for example, Japanese Utility Model Publication No. Sho 62-23730 and Japanese Utility Model Publication No. Sho 62-62.
As shown in, for example, Japanese Patent No. 40931, a pad formed by bending corrugated cardboard is used as a member for supporting a packaged body, or styrene foam having a shape along the outer shape of the packaged body is used. I was doing.

[0003]

However, a packaging apparatus using a support obtained by bending and molding corrugated cardboard requires steps such as cutting and bending of corrugated cardboard, which complicates the manufacturing process. There was an inconvenience.
Further, in a device using styrofoam, in particular, the volume must be increased in order to have sufficient strength in the pressure direction (vertical direction), and there is a disadvantage that the entire packaging device becomes large accordingly. Styrofoam was not a preferable member from the viewpoint of environmental protection.

[0004] On the other hand, a pulp mold body made of waste paper formed into a predetermined shape and dried, such as an egg pack, has been used as a part of a packaging apparatus. By using this pulp mold, no harmful gas is emitted during incineration, and since it has the same caloric combustion as paper, it can be handled in the same manner as a packaging apparatus body made of corrugated cardboard during combustion processing. However, the pulp mold body conventionally used covers the entire packaging apparatus as it is, and is merely molded into a shape that buffers external force. In other words, it has only the function of buffering external force in the thickness direction of the pulp mold body, and has the strength to withstand the load in the product pressure direction (vertical direction) like a pad formed by bending cardboard paper as in the past. Was not something with.

[0005] It is an object of the present invention to provide a packaging apparatus which can have sufficient strength against a load in the direction of pressure in the pulp mold itself and also supports a packaged object.

The present invention provides an illuminator including a main body and a glove.
A plurality of pulp molds are provided upright along the inner wall surface of the packaging device main body for accommodating the components so as to support a load in the direction of accumulation in the upper and lower surfaces, and the pulp molds are substantially L-shaped.
The side surface shape and at least the entire inner surface
Is also provided with three ribs in the direction of pressure,
Of the protrusion from the inner side of the middle rib.
Glove on the inner surface of the pulp mold body.
Support the outer surface with the glove floating from the packaging device body.
THIS wherein the Rukoto. Further, the parf mold body is provided with a notch in a pressure direction at a center portion of an outer surface .

Further, the pallet mold body is characterized in that it has a groove for holding and holding the peripheral part of the lighting fixture main body at the bottom, and a recess for fitting and holding the side of the glove on the inner surface.

[0008]

In the packaging apparatus of the present invention, a plurality of pulp molds are erected in the packaging apparatus main body, and each pulp mold is disposed along the inner wall surface of the packaging apparatus main body. In addition, the upper and lower surfaces of the pulp molded body directly or indirectly contact the bottom surface and the upper surface of the packaging device main body to directly support the load in the direction of the product pressure, and the inner surface is formed into a shape supporting the packaged object. ing. In addition, ribs are formed in the pulp mold body in the direction of the pressure in order to increase the strength in the direction of the pressure.

By using such a pulp mold body, it is not necessary to use a pad formed by bending cardboard paper as in the prior art, and it is not necessary to use a resin made of styrene foam. Since the ribs are formed in the pulp mold body in the direction of pressure, sufficient strength can be given to the load in the direction of pressure, and the inner surface of the pulp mold supports the package to provide cushioning. Since it is provided, it is possible to sufficiently provide a cushioning function against external force in the lateral direction.

Further, since the pulp mold is L-shaped, the same pulp mold can be used even if the size of the packaged object changes. In addition, the pulp mold body is on the outside.
By providing a notch in the direction of the product pressure in the center of the surface
Parep mold body by having a bendable structure
Can be installed at the corner of the packaging device body.

The packaging device in this embodiment is composed of an outer box (packaging device main body) 1 made of cardboard, four pulp molds 2, and another pulp mold 3 for supporting a lamp. ing.

The luminaire to be packaged here comprises a main body 4, a lamp 5 and a shade 6. To package the lighting device in the outer box 1, the main body 4 is placed on the bottom surface of the outer box 1, and the L-shaped pulp mold 2 is positioned at the center of the four inner walls of the outer box 1. Stand up. The pulp mold body 2 has a shape as shown in FIG. The overall shape is approximately the same height as the height of the inner surface of the outer box 1, and the upper surface and the lower surface respectively contact the top plate and the bottom plate of the outer box 1 when assembly is completed, and are L-shaped when viewed from the side. Yes, it is erected along the inner wall surface of the outer box 1. When viewed from the front, in the width direction, the ribs 2 extend along the pressure direction (vertical direction).
Nos. 0 to 22 are formed, and grooves 23 and 24 for notching a flange 40 formed around the main body 4 are cut out in the vicinity of the bottom end portions of 20 to 22 at both ends in the width direction. I have. The rib 21 at the center has a rib 2 at the bottom end.
It is cut off slightly inward as compared with those of 0 and 22, and is formed as a contact portion 25 for the flange portion 40. Further, the shape of the position of the bent portion on the inner surface of each of the ribs 20 to 22 is a concave portion R along the shape of the outer surface of the globe 6.

The pulp mold body is made from waste paper as a raw material.
It is formed by molding by using a mold and drying by an infrared heater or the like. The burned calories are almost the same as those of the cardboard paper of the outer box 1, no harmful gas is generated at the time of burning, and post-treatment (incineration, disposal) is extremely easy.

The pulp mold body 2 having the above structure
In a state in which a total of four pieces are erected along each wall surface of the outer box 1, the flange 40 on the peripheral surface of the main body 4 is
