Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing box for a refrigerator, and more particularly to a packing box suitable for packing a small refrigerator used by single persons and the like. . 2. Description of the Related Art In general, refrigerators are packaged in a manner described in
As shown in Japanese Patent No. 7830 or the like, a packing box including a bottom box on which a refrigerator main body is mounted, and an outer box with a bottom open and covered from above so as to wrap the outer periphery of the refrigerator main body mounted on the bottom box. This is done using the body. [0003] The bottom box is provided with a cushioning material formed in accordance with the bottom surface of the refrigerator main body. After the refrigerator main body is placed on the bottom box, dust adheres or scratches on the refrigerator main body. Cover with vinyl for prevention. Then, a pair of cushions formed of styrene foam (expanded polystyrene) for fixing the upper end of the refrigerator main body is placed on two opposite corners of the upper end of the refrigerator main body so as to be fitted thereto. Cover the outer box with the bottom open from the top. Further, the upper opening of the outer box is closed with an inner flap and an outer flap formed at the upper end of the outer box, and a gap between the flap and the upper surface of the refrigerator main body secured by the buffer is used. The butted portions of the flaps are stapled, and finally two packing bands are wound vertically to complete the packing. [0005] As described above, by disposing a pair of cushions at the corners of two opposing sides of the upper end of the refrigerator body,
Since the upper end of the refrigerator main body is fixed by interposing the buffer in the gap between the inner surface of the outer housing and the outer surface of the refrigerator main body, it is possible to prevent the refrigerator main body from swaying in the outer housing. [0006] However, in the packaging of the refrigerator as described above, in addition to the bottom box and the outer box, a buffer for fixing the upper end of the refrigerator body is required as a separate member. Therefore, there has been a problem that packing costs increase accordingly. In order to prevent the shock absorber from slipping off from the upper end of the refrigerator body, a part of the cushion body is formed and arranged so as to be placed on the upper surface of the refrigerator body. Therefore, there is a problem that the packing volume (packing age) increases, and the distribution cost increases accordingly. Further, since styrofoam is used as the buffer, disposal after unpacking by the purchaser poses an environmental problem. Regarding the above environmental problems, Japanese Utility Model Publication No. 5
As disclosed in Japanese Patent Application Laid-Open No. 3-5033 and the like, it is conceivable to laminate a plurality of corrugated paperboards without using polystyrene foam for the above-mentioned buffer. However, even in this case, the above-mentioned problems of the packing cost and the distribution cost are not solved at all, and the cost and labor for separately forming the laminate of corrugated cardboard are further increased, and the weight becomes heavy. Packaging and distribution costs will increase.
The problem of packing and logistics costs, especially for small refrigerators,
Since the most important issue is how to sell at low prices, it is a problem that cannot be ignored. Therefore, the present invention has been made to solve such a problem, and a buffer body separately formed of styrene foam or the like for fixing the upper end of the refrigerator body is not required, and packing cost and cost are reduced. It is an object of the present invention to provide a refrigerator packaging box capable of effectively reducing distribution costs. In order to achieve the above object, the present invention provides a bottom box on which a refrigerator main body is mounted, and an outer periphery of the refrigerator main body mounted on the bottom box. A packaging box body for a refrigerator, wherein the packaging box comprises a bottom-open outer box that is covered so as to cover the outer box, and the upper opening of the outer box is closed by an inner flap and an outer flap formed at the upper end of the outer box. On the base side of the inner flap, a buffer portion interposed in the gap between the inner surface of the outer box and the side surface of the refrigerator main body is formed by bending, and the buffer portion is formed by bending the base side of the inner flap into a concave groove shape. And an intermediate bent portion formed to be located at a vertically intermediate portion of the side piece on the inner surface side of the outer case in the concave groove-shaped buffer portion. Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a state before the outer flap of the packing box according to the embodiment of the present invention is closed, FIG. 2 is a perspective view showing the packing state, FIG. 3 is a side sectional view, and FIG. Is an enlarged view of a main part thereof, and FIG. 5 is a development view of an outer box. As shown in the side sectional view of FIG. 3, the packing box 1 is provided so as to wrap the bottom box 2 on which the refrigerator main body 100 is mounted and the outer periphery of the refrigerator main body 100 mounted on the bottom box 2. It consists of an outer box 3 with an open bottom that is covered from above. The bottom box 2 is configured in the same manner as in the related art, and has a cushioning material (not shown) formed in accordance with the bottom surface of the refrigerator body 100.
Are arranged. The refrigerator main body 100 is a so-called two-door type small refrigerator in which both the upper freezer compartment and the refrigerator compartment are openable and closable, and the left side in FIG. On the other hand, the outer box 3 is made of one piece of corrugated paper,
It is cut into a shape as shown in the developed view of FIG. 5 and formed into a bent portion as shown by a two-dot chain line or a broken line, and then assembled. That is, 4 forming each side surface of the outer box 3
Folded part 4 whose side walls 3a, 3b, 3c, 3d are indicated by two-dot chain lines
a, 4b, and 4c, and is provided so as to be freely bendable. On one side edge of the side wall 3a at one end, a folding piece 3e is provided via a bent portion 4d.
Are formed. Of the side walls 3a, 3c and 3b, 3d having the same shape which face each other at the time of assembling, the outer flaps 6a, 6c are provided at the upper ends of the longer side walls 3a, 3c via the bent portions 5a, 5c. Are formed to be freely bendable, and inner flaps 6b, 6d are formed to be freely bendable at upper end sides of the side walls 3b, 3d having a shorter lateral width via bent portions 5b, 5d. Further, in the present embodiment, in addition to the original bent portions 5b and 5d of the inner flaps, four bent portions 7b as shown by broken lines are provided at the roots of the inner flaps 6b and 6d. To 10b, 7d to 10d are respectively formed. These four bent portions 7b to 10b, 7d to 10d
Cooperates with the original bent portions 5b and 5d of the inner flap to form a concave groove-shaped buffer portion 11 as shown in FIGS. 1, 3 and 4 on the base side of the inner flaps 6b and 6d. It is provided in order to perform. Bent groove-shaped buffer portion 11 formed by bending
Is interposed in a gap between the upper end of the inner surface of the outer box 3 and the upper end of the side surface of the refrigerator main body 100 to fix the upper end of the refrigerator main body 100 so as to prevent the lateral sway or the like in the outer housing 3 during carrying or the like. ing. Note that the side wall 3 having the shorter width is used.
The horizontally long holes 12, 12 formed in the central portions of b, 3d are handle holes used for carrying. The four bent portions 7b to 10b, 7
of the original flaps 5b, 5d
The bent portions 7b and 7d which are closest to are formed so as to be located at the middle in the vertical direction of the side piece 13 on the inner surface side of the outer case in the grooved buffer portion 11 after being bent. If the intermediate bent portions 7b and 7d are not provided, in order to bend the side piece 13 on the inner surface side of the outer box 180 ° with respect to the inner surface of the outer box, the original bent portions 5b and 5d of the inner flap must be 18
It has to be bent at 0 °, which is not easy. On the other hand, the intermediate bent portion 7b,
By providing the intermediate bending portions 7b and 7d, the bending angles of the original bending portions 5b and 5d, which are inherent in the inner flap, are reduced by only slightly bending the intermediate bending portions 7b and 7d as shown in FIGS.
The side pieces 13 on the inner surface side of the outer box can be easily bent in the 180 ° direction. Accordingly, the concave groove-shaped buffer portion 11 can be easily formed by bending, and the workability at the time of packing is improved. In addition, by configuring as described above,
The original bent portions 5b and 5d of the inner flap and the intermediate bent portion 7b,
By cooperating with 7d, the degree of freedom in the thickness direction of the groove-shaped buffer portion 11 is increased and the buffering action is improved, and flexibly responds to the fluctuation of the gap between the inner surface of the outer box and the side of the refrigerator body.
The upper end portion of the refrigerator main body 100 can be fixed and held well. In assembling the outer box 3 as described above, first, the side walls 3a to 3d and the folding pieces 3e are connected to the respective bent portions 4a to 4e.
The outer box 3 is assembled by bending each at a right angle at 4d and fixing the folded piece 3e and the end of the other side wall 3d by stapling or the like to form a tubular body. On the other hand, when packing the refrigerator, the refrigerator main body 100 is placed on the bottom box 2 as in the conventional case, and then a transparent vinyl cover (shown in FIG. ) And cover the outer box 3 with the open bottom as assembled above. When the outer box 3 is put on, the inner flap 6 out of the flaps 6a to 6d formed on the upper end of the outer box 3
bent portions 7b to 10b formed on the base side of b, 6d,
7d to 10d are appropriately bent to form grooved buffer portions 11, 1
1 is formed for each. Then, the inner flaps 6b and 6d are folded inward so that the formed grooved buffer portion 11 enters the gap between the inner surface of the outer box 3 and the side surface of the refrigerator body 100 as shown in FIGS. . As a result, the buffer portion 11 at the base of the inner flaps 6b and 6d is interposed in the gap between the inner surface of the outer box 3 and the side surface of the refrigerator main body 100, and the other flat portion is placed on the upper surface of the refrigerator main body 100. Become. Thereafter, the warranty card 14 is placed on the inner flap so that the end protrudes outward, and the outer flaps 6a and 6c are folded inward to close the upper opening of the outer box 3. Then, as shown in FIG. 2, the butted portions of the outer flaps 6a and 6c are stuck with a sealing tape 15 such as a gum tape instead of a staple, and finally two packing bands 16 are wound in a vertical direction to complete the packing. I do. In the above description, the reason that the end portion of the warranty card 14 is protruded outside and sandwiched between the inner and outer flaps is to take out the warranty card 14 without unpacking at the time of sale and the like so that the date of sale and the name of the store can be entered. . In the above description, the buffer portion 11 is bent before the inner flaps 6b and 6d are folded inward. However, if the user gets used to it, first the inner flaps 6b and 6d are folded inward. By simply bending the side piece 13 on the base side so as to be pushed into the gap between the inner surface of the outer box 3 and the side face of the refrigerator body 100, the groove-shaped buffer portion 11 interposed in the gap is formed, which is extremely simple. Work. As described above, by forming the concave groove-shaped buffer portion 11 on the base side of the inner flaps 6b and 6d, a separate buffer member made of styrene foam or the like as in the related art becomes unnecessary. Therefore, the number of parts is reduced, and the packaging cost can be reduced. In addition, since it is not necessary to place a part of the buffer body as a separate member on the upper surface of the refrigerator main body, the height of the outer box 3 can be reduced to the height of the refrigerator main body 100,
Since the packing volume (packing age) can be reduced, distribution costs can be reduced accordingly. According to the present embodiment, the inner flaps 6b,
The buffer portion 11 bent in 6d is weaker in strength than a conventional buffer member made of styrene foam or the like, but the packing box 1 of the present embodiment is mainly used for packing small refrigerators. Therefore, it can function sufficiently as a buffer for fixing the upper end of a lightweight small refrigerator. As described above, according to the present invention, the buffer portion interposed in the gap between the inner surface of the outer box and the side surface of the refrigerator body is bent at the base of the inner flap of the outer box. Conventionally, a buffer body separately formed of styrofoam or the like for fixing the upper end of the refrigerator main body is not required, and the height of the outer box can be reduced to the height of the refrigerator main body. It is possible to effectively reduce distribution costs by reducing costs and packing volume. Further, the buffer portion is formed by bending the base side of the inner flap into a concave groove shape, and is formed so as to be located at a vertically intermediate portion of the side piece on the inner surface side of the outer box in the concave groove buffer portion. Because of the provision of the intermediate bent portion, the function of this bent portion allows the buffer portion side piece 18 located at the root side of the inner flap to function.
It is easy to bend in the 0 ° direction, and the buffer part can be easily formed by bending. This improves the workability during packing and contributes to the reduction of packing costs. Cooperating with the middle bent part increases the degree of freedom in the thickness direction of the groove-shaped buffer part, improves the buffering action, and flexibly responds to changes in the gap between the inner surface of the outer box and the side of the refrigerator body Thus, the upper end of the refrigerator body can be fixed and held in a good condition.
