JP 2013-159341 A

  Since the hot water storage type hot water heater has a substantially rectangular parallelepiped shape, the packaging form covers the front, back, left and right side surfaces of the packaged body with hollow prismatic cardboard. And especially in the models with large tank capacity of hot water storage hot water heaters, the product height increases in addition to the width and depth dimensions, so the amount of cardboard used as the packing material increases, and the packing material mass also increases proportionally. Become. Therefore, in the product packaging line, the work is performed in such a manner that the product is dropped while being covered with a hollow prismatic cardboard from the top of the elevated platform toward the product flowing on the lower production line. However, in the packing operation, due to the impact caused by the drop when the corrugated board reaches the assembly surface, particularly, the four corners at the lower part of the prismatic shape are likely to be significantly crushed, rubbed, torn or the like. Moreover, since the delivery form of the corrugated cardboard in the shape of a hollow prism is folded and delivered from the viewpoint of transportation and storage, the packing operator opens the covering material just before it covers the packed body and covers it. . When opening the packing material, it is difficult to lift and open it because the packing material is heavy, so it is necessary to open it against the floor surface with one of the corners of the lower four corners of the prismatic shape as a fulcrum, In that case, damage such as breakage or crushing is likely to occur at the corner portion serving as a fulcrum.

  The product name is displayed on the packing material of the hot water storage water heater, but there are many product model names for the same external dimensions, so the model name display section is a large printer dedicated to cardboard printing. Is used for printing. In the printing work, when setting the packaging material in the printer, it is folded upside down and set in the printer, but at that time also the four corners of the upper and lower sides are damaged or crushed due to bumps, rubbing, etc. There is concern about deformation. These points are factors that impair the aesthetics of the packaged state.

  The present invention has been made in order to solve the above-described problems, and external stress such as dropping, impact, friction, etc. to the load concentrating portion at the time of printing the packaging member or assembling the packaging member. An object of the present invention is to provide a packaging member that suppresses deformation due to breakage, crushing, and the like by dispersing and absorbing, and does not impair the aesthetic appearance.

  A hollow prismatic packing body configured to cover a side surface of a rectangular parallelepiped packaged body whose vertical direction is the long side, and a lower opening of the hollow prismatic packing body which is the lower side in the packing state The corner, which is the intersection of the edge, the lower opening end and the ridgeline of the hollow prismatic package, and the corner when the package is raised on the floor with the corner as a fulcrum And a collapsing prevention part formed so as to be in contact with each other or in line contact.

  According to the present invention, deformation due to breakage, crushing, etc. can be achieved by dispersing and absorbing external stresses such as dropping, impact, friction, etc. to the load concentration part during the printing operation of the packing member or when assembling the packing member. It is possible to provide a packaging member that is suppressed and does not impair the beauty.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same portions or corresponding portions are denoted by the same reference numerals, and redundant descriptions are omitted.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view of a hot water storage water heater (packed state) 100 according to Embodiment 1 of the present invention in a state in which a packaging member is assembled to a hot water storage hot water heater 10, and shows the front and right side surfaces. Yes. FIG. 2 is an exploded view showing the component configuration position of each packing member with respect to the hot water storage type hot water heater 10 according to Embodiment 1 of the present invention in an expanded state.

  The packing member is the lower wooden frame 20, the lower cushion 30 made of corrugated cardboard, the trunk packing member (b) 40 made of corrugated cardboard (corresponding to the packing body of the present invention, and the same as that corresponding to the present embodiment in the following embodiments) The hot water storage type water heater 10 is locked to the lower wooden frame 20 with bolts and nuts. The upper cushion 80 is made of polystyrene foam, and the upper cover 90 is made of cardboard. The first embodiment of the present invention relates to the body packaging member (A) 40 shown in FIG.

  FIG. 3 is a detailed view of the body packaging member (A) 40, which is a component of the packaging member shown in FIG. The body packing member (a) 40 has a hollow prismatic shape as a completed form, and its material is corrugated cardboard, and is formed by stapling two corrugated cardboards of the same shape at diagonal positions. doing. As for the flute direction, both vertical and horizontal cases are considered for reasons such as material dimensions and productivity of the packaging material. Although FIG. 3 shows the opened state, which is the assembled state of the body packaging member (a) 40, two corrugated boards of the same shape stapled at the aforementioned diagonal positions during transportation and storage In this state, the operator opens the trunk packing member (A) 40 to the state shown in FIG. 3 and covers the hot water storage type hot water heater 10. At that time, it is difficult to lift and open the trunk packing member (a) 40 because it is heavy, and it is necessary to open it by abutting against the floor surface using one of the lower corners as a fulcrum.

  Moreover, since the trunk | drum packing member (I) 40 depends on the magnitude | size of the hot water storage type hot water supply machine 10 and a height dimension may exceed 2 meters depending on the kind, the hot water storage type hot water supply machine 10 is packed. In the product packaging line, the packaging work is performed in such a manner that the product packaging line is dropped from the elevated platform toward the hot water storage type water heater 10 flowing on the lower production line. At that time, due to the impact caused by the drop when the body packing member (a) 40 reaches the lower wooden frame 20 that is the assembly surface, particularly the four corners at the lower part of the prismatic shape are significantly crushed, rubbed, torn, etc. As shown in FIG. 3, the lower notch 40a (corresponding to the collapsing prevention portion of the present invention, which is described below, is cut by chamfering across the ridge at the lower four corners as shown in FIG. The same applies to this configuration), and eliminate the vertices that have been intensively loaded so far and receive the load on the chamfered surface to distribute the load and prevent deterioration of the appearance due to crushing Can do.

  Also, conventionally, when the flute direction of the body packaging member (a) 40 is the same vertical direction as the direction in which the load is applied, it is advantageous in terms of strength against crushing of the lower portion, and the flute direction has When the horizontal direction is added to the direction of addition, there is a problem that it tends to be weak against the crushing of the lower part. However, the lower notch 40a shown in FIG. Since it is cut obliquely by chamfering, whichever flute direction is specified, there is an advantage that almost the same effect can be obtained against crushing and almost the same effect can be obtained.

  In addition, the lower notches 40a in the body packing member (a) 40 may be provided only at the corners on the diagonal position on the outer side during transportation and storage, for example, without being provided at all four locations. You may provide only in arbitrary places, such as providing only in the part used as a fulcrum when opening by abutting against a floor surface.

  Further, as shown in FIG. 3, the body packaging member (a) 40 has an upper notch 40b of the cut portion by chamfering at the four corners on the upper opening side as well as the lower opening (the collapse prevention of the present invention). Corresponding to this part, and the same as those corresponding to this configuration in the following embodiments). During normal packing operation, no load is applied to the upper part of the body packing member (a) 40, but in the product type name printing operation applied to the packing member, it is folded when set on a large printer. This is because the upper and lower corners are set in the printer so that the upper four corners are liable to be damaged or crushed by deformation or the like.

  In addition, the upper notch 40b in the body packing member (b) 40 is not provided in all four places, for example, provided only in the corner of the diagonal position on the outer side during transportation and storage. You may provide only in arbitrary places.

The upper folding portion is provided at the four corners on the upper opening side of the body packaging member (d) 70. 70b is shown. The reason for the attachment is the same as in the first embodiment. The lower folding portion 70a and the upper folding portion 70b in the trunk packaging member (d) 70 may not be provided at all four locations, but may be provided only at arbitrary locations as described in the first embodiment.

  In addition, the cut part and folding part (collapse prevention part of this invention) which were provided in each trunk | drum packaging member in the above-mentioned Embodiment 1-4 can also be attached by mixing multiple types.

  In each trunk | drum packing material shown by Embodiment 1-4 demonstrated above, an effect is included including the operation | movement at the time of expand | deploying from the folded state. For example, in the case of the first embodiment, as shown in FIG. 7 (A), from the state in which the body packaging member (a) 40 is folded, the A portion fulcrum is abutted against the floor surface and the arrow in the figure 7B, as shown in FIG. 7B, the lower notch 40a of the body packaging member 40 (a) is formed so as to be in line contact with the floor surface. The load generated at the contact portion is dispersed and the deterioration of the appearance due to crushing can be prevented. Similarly, in the case of external stress such as dropping, impact, friction, etc., the load is distributed by the lower notch 40a and the upper notch 40b, so that deformation due to breakage, crushing, etc. can be suppressed and the aesthetics can be impaired. No packaging member can be provided. This effect is the same when applied to the second to fourth embodiments.

  Further, in the first to fourth embodiments, the structure corresponding to the collapse preventing portion of the present invention provided on the lower side of each body packaging material (lower notch portion 40a, lower notch portion 50a, lower notch portion 60a, lower portion The folding part 70a) may be formed only in one place. For example, in the case of the first embodiment, as shown in FIG. 8, by forming the lower notch 40a only at one lower portion, the following effects can be obtained in addition to the effects described above. That is, when the trunk packaging member (a) 40 is set on the lower wooden frame 20 during the packing operation, the positioning convex portions 20a and 20b with the trunk packaging member (a) 40 provided on the lower wooden frame 20 are arranged. Since the fitting portion is not sweetened by the lower notch 40a only in one of the four corners of the body packing member (a) 40, the body packing member (a) 40 and The problem that positioning with the lower wooden frame 20 becomes ineffective can be solved. This effect is the same when applied to the second to fourth embodiments.
