Abstract

(57) [Abstract] [Purpose] Pollution occurs when a packaging protective body that has an L-shaped cross section or a U-shaped cross section to be fitted on the outer edge of an article such as furniture is treated as garbage after use. Do not make it from paper so that when the packaged items are stacked, the protective body will not be crushed and deformed or broken by bending,
In addition, it should be possible to manufacture at low cost. [Structure] The protector 1 is formed of laminated paper in which kraft paper 3 is adhered to both front and back surfaces of flexible cardboard such as milk carton paper 2. Since the whole is cardboard-shaped, it is not crushed and deformed by the load of the article A, and since the cardboard 2 having flexibility is used as the core material, it does not break even when folded. In addition, since the front and back surfaces of the cardboard 2 as the core material may be printed or coated with the synthetic resin film 2b, waste paper generated in the manufacturing process of a paper container or the like can be used as a material. Therefore, the manufacturing cost can be reduced.

[Industrial applications]

 The present invention relates to an improvement of a protector which is fitted to an outer edge of an article such as wooden or steel furniture from the outside in order to protect the outer edge of the article from an external impact in packaging the article. Is.

[0002]

[Prior Art]

 As shown in FIG. 14, generally, a rectangular article A such as furniture is packaged in a corrugated cardboard packaging box B. However, since corrugated cardboard is easily crushed by an impact, it is packaged after the article A is packaged. If another object hits the edge of the box B, or the outer edge of the box B hits another object or the wall of the building during transportation or storage after packaging, the edge of the box B will be damaged. There is a case where it is crushed and damaged or deformed to the edge corner portion A1 of the article A. Therefore, when packaging the angular article A, generally, the protector 20 having an L-shaped cross section is attached to the edge corner portion A1 of the article A. I am trying to fit it.

The conventional protector 20 is made of a soft synthetic resin such as vinyl chloride or polyethylene, and is attached to the edge corner A 1 of the article A in a linearly extended state. A slit 21 having a longitudinal opening is formed on one side plate 20a of the protector 20 so that the other side plate 20b of the protector 20 can be bent at the base of the slit 21. As a result, as shown by the alternate long and short dash line in FIG. 11, the corner portion A2 of the article A is covered with one protector 20.

[0004]

[Problems to be solved by the device]

 By the way, the protective body 20 of this kind is treated as garbage after unpacking the article A, and is incinerated at the incineration site, or is disposed at a landfill or a garbage disposal site in the mountains. However, if the protector 20 is made of a synthetic resin such as vinyl chloride or polyethylene as in the conventional case, toxic gas is generated during incineration, which damages the environment and shortens the life of the incinerator, while at the same time, the landfill site. Just as there is a risk that toxic substances may flow out and pollute the water quality for many years if it is discarded in the mountains, there is a problem that pollution occurs when it is treated as garbage.

For this problem, it is considered that the protector 20 may be made of paper such as cardboard and thick kraft paper. However, forming the protective body 20 from cardboard has the advantage that it can be bent easily, but on the other hand, cardboard is weak in compressive force, so that a plurality of packaging boxes B containing the articles A are stacked. In this case, the weight of the article A located at the upper stage causes the protective body 20 for the article A located at the lower stage to be flattened and deformed, and the packaging box located at the lower stage as shown by the one-dot chain line in FIG. The side wall B1 of B is bulged outward in a convex shape or is deformed, or only a part of the plurality of protective bodies 20 arranged along the outer periphery of the upper surface or the lower surface of the article A is crushed. There is a problem in that the upper packaging box B is deformed and tilted.

On the other hand, if the protector 20 is formed of thick paperboard such as kraft paper, the protector 20 will not be crushed and deformed due to the weight even if the packaged articles A are stacked, but the protector 20 and so-called horse manure paper will not be deformed. Since the flexibility of the paperboard is extremely reduced when the thickness thereof is increased, the band-shaped material plate is bent to have an L-shaped cross section to form the protective body 20, or the other side plate 20b of the protective body 20 is used at the time of use. When it is bent as shown by the alternate long and short dash line in FIG. 14, as shown in FIG. 16, the bent portion is broken and cut into pieces, which is a fatal defect that the protective function of the article A cannot be fulfilled. There is.

According to the present invention, it is possible to inexpensively manufacture a paper-made protector that does not cause problems such as stacking of articles after packaging and loss of a protective function for the articles. It is intended to be provided by.

[0008]

Means for Solving the Problems To achieve this object, the present invention provides a protective body for packaging which is formed into an L-shaped cross section or a U-shaped cross section so as to be fitted from the outside to an outer edge portion of an article such as furniture. Is made of laminated paper made by sticking kraft paper on both front and back sides of flexible cardboard such as milk carton paper.

[0009]

[Operation and effect of the device]

 With this structure, since the protector is made of paper, it does not generate toxic gas when it is incinerated as waste after use, nor does it leak toxic substances when buried in the soil. No pollution will occur during processing. In addition, both thick paper such as milk carton paper and kraft paper have high density, and the laminated paper that is the material is in the form of thick paper as a whole.Therefore, the protector is fitted on the outer edge of the article and the articles are stacked in multiple stages. However, since the protector does not collapse and deform, and because flexible cardboard such as milk carton paper is used as the core material, the strip-shaped laminated paper of the material is L-shaped or U-shaped in cross section. The material laminated paper is not broken when the protective body is formed by folding it into a sheet or the like, and the side plate is not broken when the side plate of the protective body is bent during use.

[0010] According to the present invention, therefore, even though it is a paper-made protector, it does not crush and deform due to the weight of the articles or break when folded, so that the stacking function of the articles after packaging is impaired, It has the effect of reliably preventing the occurrence of pollution when treating it as waste after use without impairing the protection function of.

Further, since waste paper generated when manufacturing a packaging container or the like made of milk carton paper can be used as a raw material, there is an effect that it can be manufactured at a low cost. That is, in order to manufacture a box-shaped container for packaging liquids such as milk, soft drinks, or sake with milk carton paper, a wide roll of paper is rolled out in the longitudinal direction. First of all, various indications such as quality indications and trademarks are printed in advance at multiple points along the width direction of the original sheet of paper, and the container is expanded at each of the printed points. It is performed in the process of punching out into a single sheet of paper, assembling and pasting this single sheet of paper, and when manufacturing this container, since it is necessary to transfer the original sheet of paper, In addition, both side edges remain with a considerable width without being used, and due to misalignment of printing spots, some defective single paper cannot be manufactured in the container.

The side edges and defective products of a raw paper sheet, which are generated in large quantities in the manufacturing process of these containers, have been conventionally melted and used for recycled paper. Good products have a considerable area, and because milk carton paper is required to be waterproof and processable, it is manufactured by a special manufacturing method using high quality long fibers, and it has high flexibility even if it is thick. Therefore, the side edges of the paper roll and the defective products in these milk carton papers are suitable as the material of the protector.

However, the side edges and the defective products of the paper rolls of these milk carton papers have various indications that form the outer surface of the container printed on one surface thereof and the other surface thereof. Since a synthetic resin film for waterproofing is laminated, if these side edges of paper stock or defective products are directly used as a protective body, the protective body will adhere to the surface of the article, so printing will be performed on the surface of the article. However, there is a problem that the synthetic resin film adheres to the surface of the article.

However, the protector according to the present invention is a laminated paper having a three-layer structure in which both front and back surfaces are made of kraft paper, and is printed on the front surface or the back surface of the cardboard such as milk carton paper as the core material. Even if it is coated or laminated with a synthetic resin film, the printing and the synthetic resin film will not adversely affect the products at all, so protect the products that were previously treated as waste. It can be used as a material for the body, thus saving significant material costs and significantly reducing manufacturing costs.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. 1 to 7 show a first embodiment, and in the drawings, reference numeral 1 is an L-shaped cross-section that is appropriately fitted to an edge corner A1 as an example of the outer edge of the article A. As shown in FIG. 2, the protective body 1 has a length, and the protective body 1 includes a paper 2 for a milk carton, which is formed by coating a synthetic resin film 2b such as polyethylene on one surface of a flexible paperboard 2a, The milk carton paper 2 and the kraft paper 3 attached to both front and back sides are formed into three layers, and slits 4 extending in the direction orthogonal to the longitudinal direction are formed at the left and right ends of the side plate 1a of the protective body 1. The other side plate 1b of the protector 1 can be bent at the slit 4 by forming a cutout.

The method of using the protector 1 is the same as the conventional method, and when the article A is stored in the corrugated cardboard packaging box B, as shown by the solid line in FIG. As it is, it is fitted on the edge corner A1 of the article A, or the other side plate 1b of the protective body 1 is bent at the slit 4 and the corner A2 of the article A is covered at the bent point, and then the packaging box. By fixing the flap B2 of B with an adhesive tape or the like, each protector 1 may be maintained so as not to fall between the outer surface of the article A and the inner surface of the packaging box B.

When the article A is not stored in the packaging box B, the protector 1 is fitted on the edge corner portion A1 of the article A in the same manner as described above, and then, as shown by a chain double-dashed line in FIG. Then, the band tape C may be wound around the article A so as to overlap the protection body 1, and the protection body 1 may be fixed to the article A by the band tape C. Since the protector 1 is made of flexible cardboard such as milk carton paper 2 with a core material and the kraft paper 3 attached to both front and back sides thereof, a belt-shaped material plate is L-shaped in cross section. When the protective body 1 is formed by bending it in a circular shape or when the other side plate 1b of the protective body 1 is bent during use, it is not broken at the folding point and is not torn. Even if A is stacked in a plurality of stages, the protective body 1 will not be crushed and deformed.

By the way, in order to manufacture a box-shaped container D for packaging milk, sake or the like in milk carton paper, as shown in FIG. First, various indications 6 such as a quality indication and a trademark are printed on the surface of the original sheet 5 in advance along the width direction of the original sheet 5, and then printed. This is done in the process of punching the container D into the expanded shape at each printed location (the punching shape is simplified in the drawing), then assembling and pasting the punched paper unit 7. During the manufacture of the container D, since the raw paper sheet 5 is transferred, both side edges 5a along the longitudinal direction of the raw paper sheet 5 are left with a considerable width without being used, and a printing portion and a punching portion are formed. Can be assembled into container D due to misalignment etc. A defective single sheet 7 is also generated.

The side edge portions 5a of the raw paper sheet 5 and the defective products have a considerable area and can be used as a material for the protective body 1, but the side edge portions 5a of the raw paper sheet 5 and The defective product has various indications 6 printed on one surface thereof, and the synthetic resin film 2b is coated on the other surface thereof. If is used as the protective body 1 as it is, since the protective body 1 adheres to the outer surface of the article, various indicators 6 may be transferred to the surface of the article A or the synthetic resin film 2b may be attached to the surface of the article. Occurs.

However, the protector 1 according to the present invention has a structure in which the milk carton paper 2 or the like is used as a core material and the kraft paper 3 is attached to both front and back surfaces of the milk carton paper 2. Even if the synthetic resin film 2b remains, the printing and the synthetic resin film 2b do not have a bad influence on the article A at all. Alternatively, the used container D or the like can be used as a material, and therefore, the material cost can be saved and the manufacturing cost can be remarkably reduced.

FIG. 8 shows that when the other side plate 1b of the protector 1 is bent so that one protector 1 can cover the corner A2 of the article A, the protector 1 The V-groove 11 is cut open in the one side plate 1a, and the other side plate 1b is configured to be bendable with both end surfaces of the V-groove 11 in contact with each other. On one side edge 1c of the V-shaped groove 11, a circular engagement protrusion 8 is provided so as to project, while on the other side edge 1d of the V-shaped groove 11, a circular engagement groove 9 for the engagement protrusion 8 is cut out. By bending the other side plate 1b by 90 degrees and fitting the engaging projections 8 into the engaging grooves 9, the bent state of the other side plate 1b is maintained.

According to this structure, when the corner portion A2 of the article A is covered with one protective body 1, the upper surface of the protective body 1 becomes flat, in other words, the thickness of the upper portion of the protective body 1 is measured. Therefore, when stacking the packaged articles A, the stability of the article A positioned in the upper stage can be further improved, and the other side plate 1b is bent to engage the engagement projections 8 with the engagement grooves. Since the protector 1 can be held in a state of being bent at a right angle in a plan view only by fitting it in 9, it has an advantage that the efficiency of the packaging work can be improved.

As shown in FIG. 9, a V groove 11 is formed by cutting out the end portions of the side plates 1 a and 1 b of the protective body 1, and the side plates 1 a and 1 b are formed at the root portions of the V groove 11. It can be bent inward along the crease line 10 so that both side edges 1c and 1d of the V groove 11 can be brought into contact with each other so as to cover the three surfaces of the corner angle portion A2 of the article A. Further, the left and right side edges 1c and 1d of the V groove 11 are formed with a pair of engaging protrusions 8 and pair of engaging grooves 9 capable of holding the contact state of the both side edges c and 1d. It is a thing.

Further, FIG. 10 shows a modified example of the embodiment of FIG. 8, in which a V-shaped groove 11 is cut open in one side plate 1 a of the protective body 1, and the left and right side edges 1 c of the V-shaped groove 11 are formed. In FIG. 1d, an engaging projection 8 having a rectangular shape in plan view and an engaging groove 9 having a rectangular shape in plan view in which the engaging projection 8 is fitted are formed in pairs. FIG. 11 shows that the protective body 1 is formed in a U-shaped cross section, and the outer edge portion of a plate-like member that constitutes an article such as a top plate A 1 or a leg A 2 of a desk A ′ or a kotatsu plate. It is designed to be fitted on the outer edge of such a plate-like article.

In this case, by forming the two sandwiching plates 1e of the protective body 1 extending in opposition to each other so that the interval E between the two sandwiching plates 1e, 1e becomes narrower toward the free end, A plurality of types of top plates A1 and the like having different thicknesses T can be elastically sandwiched by one type of protective body 1. With this structure, the protective body 1 is fitted onto the top plate A1 and the like. Since the condition can be maintained, the efficiency of the packaging work can be improved.

Further, the V-grooves 11 are formed at one place or a plurality of places on both the sandwiching plates 1e, 1e so that the protective body 1 can be bent into a U-shape or an L-shape. Since the top plate A1 and the like can be sandwiched between the two sandwiching plates 1e and 1e in the width direction thereof, the protector 1 can be secured to the V-groove 11 at the location of the V-groove 11 without providing an engaging projection and an engaging hole at the V-groove 11. It can be held in a bent state.

When the protector 1 is formed in a U-shaped cross section, as shown in FIG. 13 (A), the V groove 11 may not be provided, or as shown in FIG. 13 (B). Part of the protector 1 is formed by forming only the portion outside the two V-shaped grooves 11 in a U-shaped cross-section and forming the portion between both V-shaped grooves 11, 11 in an L-shaped cross-section. It may be formed in a U-shaped cross section.

In the above-mentioned embodiment, the protective body is formed in an L-shape or a U-shape in cross section. It should be in a form that suits to. In the present invention, a plurality of flexible cardboards such as milk carton papers may be stuck together, and kraft paper may be stuck on both front and back surfaces thereof.
