Description

[Detailed Description of the Invention] <Technical Field> This invention relates to a cushioning packaging material for automobile heater units, etc., and more particularly, to a cushioning packaging material for articles with protruding parts such as heater units, which are automobile parts.

<Background and Prior Art> Conventionally, when packaging various mechanical parts that have thin pipes or rods protruding from their outer surfaces, such as heater units for automobiles, it has been necessary to sufficiently protect the thin and easily damaged protruding parts. For this purpose, the entire product with protruding parts was individually wrapped in a buffer sheet to protect the protruding parts, or only the protruding parts were specially wrapped, but these methods were time-consuming and time-consuming. Therefore, packaging a large number of articles with protrusions is extremely wasteful in terms of storage efficiency and packaging cost, and improvements have been desired.

<Purpose> This invention solves the above-mentioned problems with conventional packaging for articles with protrusions, and provides cushioning packaging for automobile heater units, etc., which is efficient in storage, economical in terms of packaging cost, and convenient to use. The purpose is to provide materials.

<Structure> The structure of this invention to achieve the above object consists of an upper packaging material, an intermediate packaging material, and a lower packaging material, which are entirely made of synthetic resin foam, and are suitable for heating units, etc. At least two articles with protruding parts are stored horizontally between each packaging material in pairs with the middle part of the article exposed, and the upper surface of the lower protruding article is placed on the lower surface of the upper packaging material. A storage recess is formed on the upper surface of the intermediate packaging material, and a storage recess is formed on the upper surface of the intermediate packaging material. A storage recess is formed on the lower surface of the packaging material to fit only the upper surface side of the article with the lower protrusion to an appropriate depth, and furthermore, the upper surface of the lower packaging material is formed with a storage recess that can be fitted only to the appropriate depth on the lower surface side of the article with the upper protrusion. A storage recess is formed into which the packaging material can be fitted, and the storage recesses of each of the packaging materials are shifted diagonally from each other so that the protrusion sides of the left and right protrusion-equipped articles stored horizontally face each other alternately. It consists in that the two pieces are formed symmetrically.

<Example> Next, an example of this invention will be illustrated below with reference to the drawings.

The buffer packaging material of this invention uses a combination of three types of packaging materials: an upper packaging material 1, an intermediate packaging material 2, and a lower packaging material 3.
3 is also generally rectangular in shape and is entirely molded from a synthetic resin foam such as expanded polystyrene.

A pair of heater units H are housed between each packaging material with the middle part exposed, and a pipe P for hot water protrudes from a part of the heater unit H. Two heater units H are arranged with their protruding pipe P sides facing each other alternately (see FIG. 12).

Of each packaging material, on the upper surface of the intermediate packaging material 2 and the lower packaging material 3, reference numerals 20 and 30 are storage recesses on the lower surface side of the heater unit H, which is an article with a protrusion. 30,3
0 are formed symmetrically with each other diagonally shifted.

Reference numerals 21 and 31 are storage portions for the pipes P which are the protruding portions of the storage recesses 20 and 30, and these storage portions 21 and 31 for the protrusion do not interfere with the opposing storage recesses 20 and 30, and are sufficiently spaced. It is located close to.

Next, on the lower surfaces of the upper packaging material 1 and the intermediate packaging material 2, reference numerals 10 and 20' are storage recesses on the upper surface side of the heater unit H;
A pair of recesses 10 and 1 are provided at positions facing 0, respectively.
0 or 20', 20' are formed symmetrically and offset from each other in the diagonal direction as described above. Note that, although no storage space for the protrusion is formed in the storage recesses 10, 20', depending on the shape of the article such as the heater unit H, a storage space for the protrusion may be formed on the side of the storage recesses 10, 20'. may form.

Each of the storage recesses 10, 20', and 30 is formed so that it can be fitted only to an appropriate depth on the upper surface side or lower surface side of the heater unit H, so that the middle portion of the heater unit H is exposed. It will be sandwiched between the upper and lower packaging materials (see Figure 11). Reference numerals 12 and 22 are gripping recesses, which are recessed below the side ends of the upper packaging material 1 and the intermediate packaging material 2, and are used for removing or lifting the respective packaging materials 1 and 2.

The detailed shape of each packaging material 1, 2, 3 described above,
In particular, the shape of the storage recesses 10, 20, 20', and 30 can be freely changed depending on the form of the protrusion-equipped article to be stored, and is not limited to what is shown in the drawings. In addition, storage recesses 10, 20, 2
In addition to forming only two pairs of 0' and 30 on each surface of the packaging materials 1, 2, and 3, multiple pairs of storage recesses 10...
By arranging them in parallel, a larger number of heater units H etc. can be packaged at the same time.

Furthermore, in the illustrated embodiment, two intermediate packaging materials 2 are arranged between the upper packaging material 1 and the lower packaging material 3, but the number of intermediate packaging materials 2 used may be one or three. It is possible to freely increase or decrease the number.

<Effects> According to the cushioning packaging material of this invention constructed as described above, an article with a protruding part such as a heater unit is stored between the upper and lower packaging materials in a sandwiched state with the middle part of the article exposed. , as if the packaged goods were
It looks as if it is integrated with the packaging material, and compared to the conventional case of packaging the entire product with protrusions, it is possible to save much material on the packaging material, and the packaging process can be stored sequentially, making it very easy. , which can be protected with good cushioning properties by the synthetic resin foam.

In each packaging material, a pair of items can be stored with the protruding parts facing each other and being shifted diagonally from each other, so there is no wastage of storage space, it can be stored compactly, and the protruding parts that are easily damaged can be stored. The heater unit can be suitably protected without interfering with or coming into contact with adjacent heater units.

Moreover, since the packaging material is divided into an upper packaging material, an intermediate packaging material, and a lower packaging material and is used in combination, handling and manufacturing of the individual packaging materials is easy. By increasing or decreasing the number of intermediate packaging materials, the number of heater units to be stored can be changed freely, and it has various advantages such as being highly flexible and convenient, and is of high practical value.
