  However, because of the problem of restrictions on the loading height of the transport vehicle and the height of the ceiling of the loading platform or warehouse, a tall product cannot secure a sufficient thickness for the packaging top cover 42. There was a problem that the performance deteriorated.

  In order to prevent the vehicle from falling over, the loading platform of the vehicle is often hung and tied with a rope on the top, and there is a problem that the product is deformed by local stress caused by the rope.

  Further, even when the product falls, there has been a problem that the product is deformed due to ridgelines and corners around the top surface colliding with the wall surface.

  This invention solves the said subject, and it aims at providing the packaging member which packages the product which suppressed the deformation | transformation of the product at the time of transport.

In order to achieve the above object, the packaging member of the present invention fixes a packaging top cover that protrudes on the side surface of the product that is a substantially rectangular parallelepiped, a side cover that covers the side of the product, and a bottom surface of the product A packaging fixing base, and a ring-shaped packaging band for fastening the packaging top cover and the packaging fixing base, with a rigid reinforcing plate between the packaging top cover and the product, A packaging top cover is attached to the upper surface of the product , and the packaging top cover is composed of a single cardboard box having upper and lower flaps, and the upper flap is folded inward by 90 degrees to form the top surface of the outer box. The lower flap forms a side surface corresponding to the four side surfaces of the product from a double structure folded inward by 180 degrees, further folds the lower flap downward at the upper flap folding position, and further outwards of the lower flap Is bent so that the upper flap and the lower flap are in close contact with each other at the place where the lower flap abuts against the upper flap, By making the end faces of the four different lower flaps abut each other, the ridges and corners on the top part side are reinforced to ensure buffering performance against local stress on the product top part, and the thickness of the packaging top cover By reducing the height of the packaging and lowering the packaging height, the transporting workability can be improved.

  The present invention can provide a packaging member for packaging a product in which the product is prevented from being deformed during transportation.

A packaging member according to a first aspect of the present invention is a packaging top cover projecting on a side surface on a product upper surface that is a substantially rectangular parallelepiped, a side cover that covers the side surface of the product, and a packaging fixing base that fixes the bottom surface of the product. The packaging top cover and a ring-shaped packaging band for fastening the packaging fixing base, and the packaging top cover is attached to the product via a rigid reinforcing plate between the packaging top cover and the product. The packaging top cover is attached to the upper surface, and the packaging top cover has a single cardboard box with upper and lower flaps.
-The upper flap is folded inward 90 degrees to form the top surface of the outer box, and the lower flap is formed from a double structure folded inward 180 degrees to form side faces corresponding to the four side faces of the product. Further, the lower flap is folded downward at the upper flap folding position, and further, the reinforcing plate is formed by folding upward so that the outer surface of the lower flap is in contact with the side surface of the product. Reinforce the ridges and corners on the top side by bending the upper flap and the lower flap so that they come into close contact with each other at the place where they hit the upper flap, and by making the end faces of the four different lower flaps come into contact with each other. As a result, buffering performance against local stress at the top of the product can be secured, and the thickness of the packaging top cover can be reduced to lower the packaging height, thereby improving transport workability. Rukoto can.

Further, the packaging top cover and the reinforcing plate are integrally formed, so that resource saving of the packaging material can be realized.

Moreover, the packaging top cover which protrudes on the side surface side of the product is composed of four surfaces in an integrated manner and can be doubled, so that a very high strength against external impacts can be obtained. In addition, the number of parts is reduced, making assembly easier and contributing to productivity improvement.

  In addition, the cross section of the corrugated ball has a honeycomb structure, the portion where the end faces match is strong, and the impact applied to the packaging top cover is dispersed and transmitted to the place where the end faces match, leading to the product. Since the load is not applied, it is possible to reduce a problem that the product is deformed. In addition, when folding the packaging top cover from one cardboard box, it was necessary to prepare an adhesive tape fixing or a special tool in order to suppress the repulsion of the material, but different lower flaps had their own Since the shapes are held together by repulsive forces, assembly is easy, contributing to productivity improvement.

  Furthermore, since the side surface of the packaging top cover is doubled and strong, a hand hole can be provided, the product handling performance can be improved, and the occurrence of a fall accident or the like can be reduced.

According to a second aspect of the invention, in particular, in the first aspect of the invention, the foamed resinous cushioning material is disposed in a space surrounded by the lower flap that forms the reinforcing plate and the upper flap that forms the top surface. Further, the buffering property is improved against the vertical weight with respect to the top surface and the side surface, and the buffering performance is improved when products are stacked or placed horizontally.

According to a third aspect of the invention, in particular, in the first or second aspect of the invention, since the packaging top cover is formed by using a corrugated board having waterproofness and rigidity, the ridgeline and the corner have rigidity, so that the packaging In addition to ensuring the strength of the top cover, the top cover and the vertical surface are buffered against heavy loads, and the cushioning performance is improved when products are stacked or placed horizontally.

  And even if the heavens get wet with water, such as in rainy weather, not only can the buffering performance be maintained, but products that were impossible in the past can be stored aside in the outdoors. This is because the product can be supported by the sufficient strength of the packaging top cover and it can be stored for a long time without sucking moisture from the ground.

FIG. 6 is a front perspective structure assembly diagram, and FIG. 1 to 6, the product main body 1 of a CO2 heat pump water heater having a tall and substantially rectangular parallelepiped shape is used as a product in the present invention.

  The bottom has a flat bottom plate 2 and a convex leg 3 having an anchor bolt fixing hole 3-1, and the top part covers the entire side from above and is fixed from the side with screws. The top plate 4 has an edge, the front plate 5 is detachable and has the operation portion 5-1, and the exterior plate 7 is fixed by bending and screws. Further, the top plate 4 is designed to be thicker so that a seismic fixing bracket can be attached when the product body 1 is installed.

  The packaging top cover 7 is fitted to the top plate 4 of the product body 1. Reference numeral 9 denotes a packaging fixing base, which is a member on which the product main body 1 is mounted by fastening the convex leg 3 with bolts and nuts using the anchor bolt fixing holes 3-1, and is made of a wooden material. The shock applied during the fall is buffered, and it is prevented from being damaged even when grounded on the ground having moisture or soil containing gravel outdoors.

  Both side plates 10 cover the two sides and protrude forward and backward, and are configured to face each other.

  The U-shaped panel 11 disposed opposite to the front and rear has a tote hole 11-1 disposed so as to overlap with those of both side plates 10.

  A ring-shaped packaging band 12-1 fastened in the up-down direction fixes and fixes the packaging fixing base 9 and the packaging top cover 7 to the product main body 1 in the up-down direction.

  Moreover, the ring-shaped packaging band 12-2 fastened from the side is fastened facing the front and rear so as to cover both side plates 10.

  The tote hole 11-1 is used by a loader to hang a hand and move it, and is arranged in the vicinity of the ring-shaped packaging band 12-2 in order to transmit the power of the hand as efficiently as possible. There are two positions: a position where a person stands and works, and a position where the person leans a little to put power. As a result, it is possible to prevent a cut accident caused by gripping and operating the band. Further, since the front and rear surfaces and the side surfaces are integrated by the hole, the packaging member does not come off, and the safety and stability of the transportation work can be realized.

  The front plate 5 has an operation unit 5-1, and has a main body control component in the vicinity of the inside of the operation unit 5-1. In general, horizontal loading on the loading platform of the transport vehicle and application work to the loading platform Is performed on the rear surface, and not only the workability is improved by grasping the L-shaped reinforcing plate 8, but also a problem that the foamed resin body is gradually deformed by vibration is prevented.

  The packaging top cover 7 is composed of one cardboard box having flaps on the upper and lower sides of the side surface 8 corresponding to the four side surfaces of the product body 1, and the upper flap 7-1 is formed by At the boundary line 7-2 between them, it is folded 90 degrees to form the outer box top surface.

  Further, the lower flap 7-11 is folded inward by 180 degrees at a boundary line 7-3 between the lower flap 7-11 and the side surface 8 to form a double side surface by the side surface 8 and the lower flap 7-4. .

  Further, the lower flap 7-4 is bent downward at the boundary line 7-5 at a position substantially close to the boundary line 7-2 to form the lower flap 7-6. By bending upward at the boundary line 7-7 so as to contact the product main body 1, a reinforcing plate composed of the lower flap 7-6 and the lower flap 7-8 is formed.

  Then, the lower flap 7-8 and the upper flap 7-1 are bent so that the lower flap 7-10 and the upper flap 7-1 come into close contact with each other at a location 7-9 where the lower flap 7-8 and the upper flap 7-1 meet.

  With the configuration of the packaging member as described above, a product loading operation on a carrier bed of a transport vehicle, which is a problem particularly in a work environment with few human hands, will be described.

  In recent years, labor has been reduced in labor for equipment construction, and there are few workers, and in the current situation, transportation is carried out by a single person even in a tall and heavy CO2 heat pump water heater. As shown in FIG. 6, the worker holds the hand hole 8-1 of the packaging top cover 7 and lowers or raises the product body 1 from the loading platform in the manner of the operation A.

  At this time, a force a is applied from the loading platform at the contact portion between the product body 1 and the loading platform, which is supported by the joint between the U-shaped panel 11 and both side plates 10, and stress is transmitted to the product 1. It is the composition which is not done.

  In addition, if the worker is in the state of work B by an accidental hand slip, a large impact b is applied to the opposite surface. The impact b occurs at the boundary line 7-5, but the reinforcing plate prevents the deformation of the top surface of the outer box, disperses the stress and transmits it to the inner box, and the deformation of the product main body 1 that occurs due to local concentration of the stress. To prevent.

  Moreover, the packaging top cover 7 has a simple configuration with few bonded portions by integrating the inner box and the outer box, and can obtain very high strength. In addition, the number of parts is reduced, making assembly easier and contributing to productivity improvement, as well as resource saving of packaging materials.

  Furthermore, the side surface 8 can be doubled and provided with a hand hole 8-1, so that the handling performance of the product can be improved and the occurrence of a fall accident or the like can be reduced.

  In addition, by using a corrugated box, not only is the bent part rigid, but it is also buffered against heavy loads perpendicular to the top and side surfaces, and products can be stacked or placed horizontally. In such a case, the buffer performance is improved.

  In addition, the locations 8-2 and 8-3 where the end faces of the lower flaps 7-10 abut each other hold the shapes of the different lower flaps by their own repulsive forces, which facilitates assembly and improves productivity. .

  Furthermore, since the cross section of the corrugated ball has a honeycomb structure, the locations 8-2 and 8-3 where the end faces coincide with each other have strength, and the strength is maintained for a long time after assembly, and the impact during transportation is ensured. Buffered.

  Further, the foamed resin 13 can be provided as a cushioning material in a space surrounded by the upper flap 7-1 and the reinforcing plate. By doing so, the cushioning performance is improved when products are stacked or placed horizontally, in which vertical static weight is applied to the top and side surfaces.

  The packaging top cover 7 may be made of a waterproof corrugated board, and even if it gets wet in the rain, it will not only be able to maintain the shock-absorbing performance, but this is not possible in the past. Even if the product body 1 is stored while lying down outdoors, it will not absorb water from the ground, and can be stored for a long time.

As described above, spreading the heat pump water heater in the example of the present invention contributes to the prevention of global warming, and for heavy products such as hot water storage units of heat pump water heaters, Improving work efficiency is a major issue. It has been found that many of the failure factors of product deformation that occur during transportation are impacts on the ridges and corners on the top side, and the packaging member of the present invention reinforces the ridges and corners on the top side, In addition to securing the buffering performance against local stress of the part, the workability of transportation is improved by reducing the thickness of the packaging top cover and reducing the packaging height as much as possible, thereby solving the above-mentioned problems.

  In addition, since the packaging material of the present invention has a configuration in which the packaging material is folded up from one recyclable corrugated paper, it is possible to realize resource saving of the material.
