Abstract

PROBLEM TO BE SOLVED: To divide easily while maintaining cushioning function, eliminate storage-space limit, and improve the rate of storage or the rate of recycling recovery for reusing resources. SOLUTION: In both top packing cushioning-medium 11 and bottom packing cushioning-medium 21, notches 16 and 26, respectively, are made in parts where shock absorption effect is not required, they are not locked into the position of a television-receiving machine 1, an item to be packed, in contact with it, and shock absorption exerts an adverse effect on the product, and thin parts 12a and 24a, respectively, are also made in them. Thus, they can sufficiently withstand shock caused during transportation, and because dividing into two reduces volume before the division to half, each takes up only 1/2 storage space. Therefore, even in the case the packing box 4 is folded into a compact form and only the packing cushioning-mediums 11 and 21 are stored separately from it, they take up little space and also it is easy to send for recycling recovery.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing cushioning material which is space-saving, has excellent recoverability, improves reusability of resources, and can be used to promote recycling.

[0002]

2. Description of the Related Art Electrical products such as a television receiver, a video tape recorder, and a personal computer are assembled in a manufacturing plant and then packed and shipped in a cardboard box. It is common practice to apply cushioning material made of an elastic material such as styrofoam material to the corners of the four corners of the product with a suitable gap between them, and to firmly secure the product so that the product does not play in the cardboard box. is there. As a result, the product in the cardboard box is protected from external shocks during transportation or storage, and at the same time, damage to the outer casing is prevented.

FIG. 3 is an exploded perspective view exemplifying a combination of packing cushioning materials used for housing a television receiver in a cardboard box. In the figure, the cabinet of the television receiver 1 includes a front housing 2 for accommodating most of the screen portion of the picture tube, and a rear housing 3 protruding in the shape of a truncated square pyramid behind the front housing 2. Here, the packing cushioning material is addressed to the four corners of the front housing 2 and is accommodated in a packing box 4 such as a cardboard box. In the case of the present example, as the packing cushioning material, the top surface packing cushioning material 5 which is engaged with the left and right ends of the upper surface of the front housing 2 of the television receiver 1 and the left and right ends of the bottom surface of the front housing 2 are used. A bottom packing cushioning material 6 to be stopped is used.

The cushioning material 5 for packing the top surface is made of a polystyrene foam material molded into a rectangular parallelepiped shape having grooves to be engaged with left and right ends of the upper surface of the front housing 2 of the television receiver 1. The dimensions are substantially equal to the depth dimension of the bottom surface of the packing box 4. On the other hand, the bottom packing cushioning material 6 is made of a styrofoam material molded into a rectangular parallelepiped shape having grooves that engage with left and right ends of the bottom surface of the front housing 2 of the television receiver 1, and has a longitudinal dimension. Is substantially equal to the depth dimension of the bottom surface of the packing box 4.

[0005]

The above-mentioned conventional packing cushioning materials 5, 6 take out the television receiver 1, which is a product to be packed, from the packing box 4 and store it together with the empty packing box 4 in a warehouse or the like. In some cases, the storage space is limited due to the considerable volume itself, and most of the general users with limited storage space discard the storage while avoiding storage. However, there was a problem that the water content was reduced. Also, for a user who wants to store the packing cushioning materials 5 and 6 together with the packing box 4 in preparation for moving or warehouse consolidation, the packing box 4 can be folded and compactly stored, while the packing cushioning material 5 and 6 can be stored compactly.
Since 6 itself cannot be compressed to the initial volume or less, it is difficult to secure a storage space until it is used for repacking, and in some cases, it has to be discarded without stopping. Even if you choose to discard the packing cushioning materials 5 or 6 or recycle them for recycling, to cut the packing cushioning materials 5 and 6 to a size that is convenient for carrying them to a distant place, use styrofoam. It is necessary to perform operations such as chopping using a sharp cutter, and such work is unexpectedly troublesome and easy to be avoided. There was a problem to do.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and enables easy division while maintaining a buffer function, eliminates storage space limitations, and improves a storage rate or a recycling and recovery rate of resource reuse. It is an object of the present invention to provide a packing cushioning material.

[0007]

In order to achieve the above-mentioned object, the present invention relates to a method in which a packaged product is interposed between a packaged product and an inner wall of a packing box, and the packaged product is locked to an outer shell portion of the package and cushioned. In the holding cushioning material to be held, a portion which is not required to have a shock absorbing effect is formed by cutting out a part thereof, and a thin portion which is broken by concentrating a bending stress applied from outside after unpacking is provided. It is.

The present invention also relates to a packing cushioning material inserted between a packaged article and an inner wall of a packing box, and the cushioned article is latched to an outer shell portion to buffer and hold the packaged article. It is characterized in that it has a thin-walled portion formed by partially cutting out a portion that does not abut and lock, and that breaks by concentrating bending stress applied from the outside after unpacking.

Further, the present invention provides a packing cushioning material which is interposed between an article to be packed and an inner wall of a packing box, and which holds the article to be latched on its outer shell to absorb shock. It is characterized in that it has a thin-walled portion formed by partially cutting out a portion that gives an adverse effect to a packaged product, and ruptures by concentrating a bending stress applied from the outside after unpacking.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
This will be described with reference to FIG. FIG. 1 is an exploded perspective view showing one embodiment of a packing cushioning material of the present invention together with a packing example, and FIG.
It is a perspective view which shows the example of packing when the divided packing cushioning material is reused.

The packing cushioning materials 11 and 21 shown in FIG. 1 are interposed between the television receiver 1 to be packed and the inner wall of the packing box 4 made of a cardboard box, and the outer shell portion of the television receiver 1 is provided. To hold the buffer. In this case, two packing cushions 11 and 21 are respectively applied to the four corners of the front housing 2 of the television receiver 1 and the packing box 4 is provided.
Housed within. Reference numeral 11 denotes a top surface cushioning material, which is locked to left and right ends of the upper surface of the front housing 2. Reference numeral 21 denotes a bottom packing cushioning material, which is engaged with left and right ends of the lower surface of the front housing 2.

The cushioning material 11 for packing the top surface is made of a polystyrene foam material formed into a rectangular parallelepiped, and its longitudinal dimension is equal to the depth dimension of the bottom surface of the packing box 4. The top surface packing cushioning material 11 includes an upper surface portion 12, a front surface portion 13, and a side surface portion 14.
And a back portion 15, and a notch 16 having an inverted trapezoidal cross-sectional shape is formed in a horizontal direction at a substantially central portion of the upper surface portion 12. The location where the notch 16 is formed is set at a location where the shock absorbing effect is not required, that is, at a location substantially in the middle of the upper surface portion 12 which is sufficiently away from the front portion 13 and the rear portion 15 or its peripheral portion which contributes to shock absorption. It is. In addition, this part is also a connecting part between the front housing 2 and the rear housing 3, that is, a part where the impact absorption has an adverse effect on the product, and a part which does not abut and lock the packaged product, that is, the television receiver 1 It does not come into contact with the outer shell. In addition, the thickness t1 of the thin portion 12a formed by providing the notch 16 and reducing the thickness thereof so that the bending stress is concentrated on the top surface cushioning material 11 after unpacking so as to be easily broken is about 8 mm here.
The width w1 of the thin portion 12a is about 1/2 of the notch width w, about 8 mm in this case, with respect to the notch 16 having the width w of about 20 mm.

The bottom packing cushioning member 21 is made of a styrofoam material molded into a rectangular parallelepiped, and its longitudinal dimension is equal to the depth dimension of the bottom surface of the packing box 4. The top surface cushioning material 11 includes a bottom surface portion 22, a front surface portion 23, a side surface portion 24, and a back surface portion 25. A notch 26 having an inverted trapezoidal cross section is formed in a substantially central portion of the side surface portion 24 in the vertical direction. It is. The notch 26 is formed at a portion where the shock absorbing effect is not required, that is, at a substantially intermediate portion between the front portion 23 and the back portion 25 or the side portion 24 which is sufficiently far from the peripheral portion which contributes to shock absorption. It is. In addition, this part is also a connecting part between the front housing 2 and the rear housing 3, that is, a part where the impact absorption has an adverse effect on the product, and a part which does not abut and lock the packaged product, that is, the television receiver 1 It does not come into contact with the outer shell. In addition, the thickness t2 of the thin portion 24a formed by providing the notch 26 and reducing the thickness so that the bending stress is concentrated on the bottom packing cushioning material 21 after unpacking so as to be easily broken is about 8 mm here. The width w2 of the thin portion 24a is about 1/2 of the notch width w of the notch 26 having a width w of about 20 mm, here, about 8 mm.

As described above, both the top-side packing cushioning material 11 and the bottom-side packing cushioning material 21 are parts where the shock absorbing effect is not required.
Notches 16, 16 that are not in contact with and locked to the packaged item and that have a reverse effect on the product due to shock absorption.
Since the thin portions 12a and 24a are formed by providing 26, it is possible to sufficiently withstand the impact applied during transportation. Moreover, after unpacking, by applying a bending stress from the outside, this bending stress is concentrated on the notches 16 and 26, and the notch 1
It can be easily torn along 6, 26 and divided into two parts. Since the packing cushioning materials 11 and 21 divided into two are less than half of the volume before the division, each accommodating space is １ ／.
In particular, even if the packing box is folded and compacted, and only the packing cushioning materials 11 and 21 are separately stored, there is no trouble in the storage space. As a matter of course,
Whether collected or discarded for recycling, handling of the packing cushioning materials 11 and 21 is easy.

Further, as shown in FIG. 2, even when the television receiver 1 is repackaged in the packaging box 4 using the packaging buffer materials 11 and 21 divided into two parts, the packaging buffer parts divided into two parts are used. Although the parts of the materials 11 and 21 are not integral structures, they are weak in strength, but can withstand practical use in temporary storage and short-distance transportation. Can help. In addition, the packing cushioning materials 11 and 21 integrally molded from the styrofoam material are:
Select a part that does not require a shock absorption effect and cut it out.
6 and 26, the thin portions 12a and 24a are inherently exempt from the role of shock absorption, and therefore do not affect the cushioning capacity of the packaged articles, and have cutouts 16 that are easily torn. , 26 with a certain degree of freedom. Also, notch 1
6 and 26 are formed at portions that do not abut and lock on the packaged article, so that the contact areas of the packing cushioning materials 11 and 21 with the packaged article are not reduced, and the buffer capacity for the packaged article is temporarily reduced. Even if there is some influence, it is possible to reliably eliminate the possibility that the surface of the article to be packaged is damaged. Furthermore, since the cutouts 16 and 26 are formed at locations where the impact absorption has an adverse effect on the packaged product, the thin portions 12a and 24a are originally exempted from the role of the impact absorption, and therefore, are not packaged. There is no effect on the cushioning ability of the product, and the notches 16 and 26 having a shape that is easily torn can be formed with a certain degree of freedom and with confidence.

In the above embodiment, the packing cushioning material 1 is used.
Although the case where a molded article of a styrene foam material is used as the example 1 and 21 is taken as an example, the packing cushioning materials 11 and 21 may be formed of a resin molded article other than the styrene foam material. Also,
When the dimensions of the packing cushioning materials 11 and 21 are large, the cutouts 16 and 26 are formed at two or more locations to form the packing cushioning materials 11 and 21.
21 can be divided into three or more.

[0017]

As described above, the packing cushioning material of the present invention is formed by partially cutting out a portion where the shock absorbing effect is not required, and is ruptured by concentrating the bending stress applied from outside after unpacking. The thin-walled section provides almost the same drop impact resistance as conventional packaging cushioning materials, and can withstand the impact applied during transportation.Moreover, after unpacking, it can withstand external bending stress. By adding this bending stress to the notch, it easily tears along the notch and
Since it can be divided, the storage space of each packing cushioning material divided into halves having only half the volume before dividing into two is only required to be 、, so the packing box is folded and compacted, and only the packing cushioning material is separately stored. Nevertheless, there is no problem with the storage space, and even if it is collected or discarded for recycling, the handling of the packing cushioning material is easy, so the recycling and collection rate of storage and resource reuse is reduced. It is possible to improve the space merit and promote resource recycling. Furthermore, even when repacking the packaged goods in the packing box using the packing cushioning material divided into two, the packing cushion divided into two parts Although each part of the material is not integral, it is weak in terms of strength.However, it can withstand practical use in temporary storage and short-distance transportation, and can be used for repacking after achieving space-saving storage. It is possible to provide a packaging cushioning material that eliminates storage space restrictions and improves the recycling and recovery rate of resource reuse, and the notch formed in the area where shock absorption effect is not required plays the role of shock absorption. It is inherently exempted from this, so it does not affect the cushioning capacity for the packaged goods, and has excellent effects such as being able to form a notch of a shape that is easily torn with some degree of freedom and with a certain degree of freedom. Play.

According to the present invention, there is provided a packing cushioning material interposed between an article to be packed and an inner wall of a packing box, wherein the article to be packed is locked to an outer shell portion of the packing cushioning material. A part that does not abut and lock is formed by cutting out a part of the part that does not abut and lock, because it has a thin-walled part that ruptures by concentrating bending stress applied from the outside after unpacking. The notch does not reduce the contact area of the packing cushioning material with the packaged item, and even if the cushioning capacity for the packaged item may be affected somewhat, the surface of the packaged item may be damaged. Excellent effects such as the possibility of sticking can be reliably eliminated.

The present invention is also directed to a packing cushioning material which is interposed between an article to be packed and an inner wall of a packing box and which holds the article to be buffered by holding it on an outer shell portion thereof. It has a thin-walled part that is formed by partially cutting out the part that gives an adverse effect to the package, and it breaks by concentrating the bending stress applied from the outside after unpacking, so that the part where the impact absorption gives the packaged product an adverse effect is provided. Due to its formation, the thin-walled part is originally exempted from the role of shock absorption, so it does not affect the cushioning capacity for the packaged goods, and has a notch with a shape that is easily torn with some degree of freedom. It has excellent effects such as being able to be formed with confidence.
