Description

  The present invention relates to a storage container for conveying a pre-processed inner box of a refrigerator.

  In the assembly of refrigerators, small component parts such as interior lamps and capillary tubes are easy to transport, and importing those produced overseas etc. is cheaper to manufacture. Was produced in another factory and brought into the final factory.

  In this case, a large amount of capital investment is required for the so-called urethane foaming work that forms a heat insulation cabinet by filling the gap between the inner and outer boxes of the refrigerator to form a heat insulation cabinet, but large equipment is required for other assembly work. Therefore, there is a case where it is possible to produce at a lower cost if it is carried out in another factory for the assembling work (hereinafter referred to as pretreatment) of the element parts to the inner box before urethane foaming.

As a cooling unit packing method, a configuration in which a wood bottom such as a plywood board is screwed to the bottom of the refrigerator unit 4 and stored in a cardboard box is known (for example, Patent Document 1).

  However, the inner box is generally formed of a hard synthetic resin, but it is large and thin, so it is easily deformed. Also, the inner box is a large semi-assembly such as a pre-processed inner box. Conveying goods has never been considered before.

  The present invention has been made in consideration of the above-mentioned problems, and it is intended to provide a transport container for an inner box that can be transported in a good state with its shape maintained without being deformed even in a pre-processed inner box. Objective.

  In order to solve the above-mentioned problem, a transport container for an inner box of a refrigerator according to the invention of claim 1 includes a packing box that covers a side surface and a bottom surface of a pre-processed inner box, and an inner box with a front opening facing upward. And a support member that contacts the back surface of the peripheral flange portion and supports the back surface of the inner box in a state of being separated from the bottom surface of the packing box.

  According to a fourth aspect of the present invention, there is provided a transport container for an inner box of a refrigerator, comprising: a lower lid on which a front surface of a peripheral flange portion of an inner box having a front opening portion directed downward is placed; and a side surface of the inner box. It is characterized by comprising a frame for covering and an upper lid for closing the upper surface of the frame.

  According to the above invention, since the inner box is supported or placed by the peripheral flange portion having a relatively strong strength, it is possible to prevent deformation of the back portion of the inner box having a relatively low strength, which is in a good state. Can transport the inner box.

  1 embodiment of this invention is described with reference to FIG. 1 which is sectional drawing which follows the AA-line of FIG. 1 and FIG. 1 which is an exploded view which shows the conveyance container for inner boxes of a refrigerator.

  1 is the inner box which performed the pre-processing which comprises the inner wall of a refrigerator. As this pretreatment, a polyurethane foam stock solution as a heat insulating material is injected into the gap between the inner and outer boxes, and this is foamed and solidified. After the so-called urethane foaming process is finished, component parts that cannot be attached, for example, freezing A capillary tube and a suction pipe that constitute a part of the cycle, and a drain hose that drains defrost water into the machine room are attached to the back of the inner box 1, and a rail that slides the support of the drawer door is installed inside the inner box 1. It is attached to the peripheral surface via a reinforcing plate. In addition, although it is attached after the urethane foaming step, an element part that strengthens the strength of the attachment part by foaming and filling urethane, for example, the partition plate 2 that partitions the storage space of the inner box 1, It is preferable to attach to the flange part 1a bent substantially perpendicularly from the front opening part of the inner box 2 toward the outside.

  The inner box 1 that has been subjected to these pre-treatments covers the outer surface with a sheet 3 made of, for example, a polyethylene sheet so that dust or the like does not enter from the opening when it is transported. For example, the groove of the shock-absorbing material 4 formed by foamed polystyrene is fitted to protect the end face of the flange and absorb vibration and impact during transportation.

  The inner-box transport container 50 includes a packing box 10, a cushioning material 20, and a support member 30, and the packing box 10 stores the inner box 1 that has been subjected to pretreatment, and is a cardboard box. The upper surface opening is opened and closed by a lid portion 11 which is formed in a rectangular shape by, for example, and extends from the four sides of the upper surface.

  The cushioning material 20 absorbs vibrations and shocks during conveyance, is formed by foamed polystyrene, and is placed on the bottom surface 12 of the packaging box 10. As shown in FIG. 2, the cushioning material 20 is disposed in a plate shape over the entire lower surface of the inner box 1, and slits 21 are formed in the vicinity of the corner portion of the inner peripheral edge of the upper surface. Moreover, since the back surface of the inner box 1 that has been subjected to the pretreatment is uneven with element parts or the like, the uneven portion 22 is formed on the upper surface of the cushioning material 20 in accordance with the uneven shape.

  The support member 30 supports the inner box 1, and 30a and 30b, which are bent in an L shape by a corrugated cardboard board or the like according to the depth and lengthwise dimension of the inner box 1, are connected by gum tape or the like. And it forms so that the outer periphery of the inner box 2 may be covered. Further, since the side surface of the inner box 1 that has been pre-processed has irregularities due to the attachment of element parts or the like, relief holes 31 are provided on the side surfaces of the support member 30 in accordance with the convex shape.

  The support member 30 is installed so that the lower end surface 33 is fitted into the slit 21 of the cushioning material 20 so as not to be laterally shifted due to vibration during transportation, and the upper end surface 32 is brought into contact with the rear side surface of the flange portion 2 of the inner box 1. The inner box 1 is supported by contacting. Further, the height of the support member 30 is set so that a gap of, for example, about 5 mm is formed between the back surface of the inner box 1 and the upper surface of the cushioning material 20 as shown in FIG. In this case, they are not in contact with each other and are separated so as to come into contact with each other when an impact is received.

  The support member 30 may be integrally formed with 30a and 30b, and even if the outer periphery of the inner box 1 is not entirely covered, a predetermined gap is formed between the upper surface of the cushioning material 20 and the inner box 1 as described above. As long as the shape is such that it can be supported. Moreover, in the form which does not provide the shock absorbing material 20, you may make it mount on the bottom face of the packaging box 10, and may attach to the side surface of the packaging box 10 with an adhesive agent.

  Next, the operation of the present invention will be described. The inner-box transport container 50 is set in a state where the cushioning material 20 is previously placed on the bottom surface of the packing box 10 and the support member 30 is fitted in the slit 21. The inner box 1 that has been subjected to the pretreatment is placed with the front opening portion facing upward and the rear surface side of the flange portion 1 a on the upper end surface 32 of the support member 30 with the sheet 3 and the cushioning material 4 attached as described above. To do.

And it will be in the state which can be conveyed by covering the cover part 11 and sealing an opening part with a gum tape etc.

  According to the above-described invention, the flange portion 1a of the inner box 1 having a relatively strong strength is bent by the thickness of the raw material before vacuum forming. Since the inner box 1 is supported by being separated from the upper surface of the material 20, no load is applied to the back surface of the inner box 1 having relatively low strength, and deformation can be prevented.

  In the past, large items such as the inner box 1 were transported only by the inner box 1, and small element parts had to be transported separately. In the present invention, the element parts are assembled. Since the transportation cost can be greatly reduced because of the transportation, as described above, the deformation of the inner box 1 can be prevented, so that the inner box that has been pre-processed can be transported well in a state in which the shape is maintained. And manufacturing bases overseas.

  On the other hand, since the shock absorbing material 20 is provided between the back surface of the inner box 1 and the bottom surface 12 of the packing box 10, when the shock is received, the shock is applied by the shock absorbing material 20 to deform the inner box 1. Can be prevented.

  Furthermore, the support member 30 is provided over the inner peripheral edge of the packaging box 1, the upper end surface 32 thereof is brought into contact with the rear surface of the peripheral flange portion 1 a of the inner box, and the lower end surface 31 is attached to the cushioning material 20 or the packaging box 10. Since it is arranged, the inner box 1 can be reliably supported without the support member 30 being laterally displaced.

  Next, another embodiment will be described with reference to FIGS. In addition, about the thing of the same structure as the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 3 which is an exploded view of the inner-box transport container 60 of this embodiment and FIG. 4 which is a cross-sectional view along the line BB in FIG. 3, the inner-box transport container 60 is made of plastic cardboard. The upper lid 61, the frame body 62, and the lower lid 63 are formed.

  The upper lid 61 is formed wider than the outer peripheral edge of the lower lid 63, and a side wall 61c extending downward is provided on the outer peripheral edge. As shown in FIG. 4, ribs 61 a that prevent the lateral displacement of the frame body 62 are erected on the back surface. Grooves 61b are provided on the back surfaces of the outer rib 61a and the side wall 61c. When the upper lid 61 is overlaid on the lower lid 63 as shown in FIGS. 6 and 7, the lower lid 63 is placed in the groove 61b. The side wall 63b can be inserted.

  The frame 62 is disposed so that the outer wall is along the inner peripheral edge of the lower lid 63, and the height dimension is set so as to be longer than the depth dimension of the inner box 1 after the pretreatment. .

  In a state where the frame body 62 is set on the lower lid 63, it is possible to reliably prevent a lateral shift or the like by bringing the lower end surface into contact with the back surface side of the flange portion 1a of the inner box 1. Since there is a risk of deformation due to the weight of 62, the gap between the inner peripheral edge of the frame body 62 and the outer peripheral edge of the flange 1a is reduced, and as shown in FIG. By attaching, a lateral shift etc. can be prevented, without the inner box 1 deform | transforming.

  The front and rear surfaces of the side wall of the frame body 62 are provided with bent portions 62a in the vertical direction. As shown in FIG. 6, when the transport container 60 is folded, the frame body 62 is rotated by 90 degrees. The frame 62 is deformed into a flat plate shape by bending the bent portion 62a inward.

  The lower lid 63 is formed along the outer periphery of the flange portion 1a of the inner box 1, and a side wall 63b extending upward is formed on the outer peripheral edge thereof. Further, the lower cover 63 is provided with a stopper 63a that prevents the element part 65 from moving due to vibration or the like so that other element parts 65 packed in the box can be transported using the opening space of the inner box 1. It stands up from the top.

  Next, the operation of the present invention will be described. When packing the inner box 1 with the inner-box transport container 60, the bent portion 62a of the frame body 62 is spread in advance and rotated 90 degrees to stand upright in the side wall 63b of the lower lid 63. The pre-processed inner box 1 is placed on the lower lid 63 with the front opening facing downward. At this time, when the other component parts 65 are also transported, they are disposed on the stopper 63a before the inner box 1 is placed.

  Then, the upper end surface of the frame body 62 is fitted between the ribs 61a, the upper surface opening of the frame body 62 is closed by the upper lid 61c, and as shown in FIG. Thus, the upper lid 61 and the lower lid 63 are prevented from being removed.

  After transporting the inner box 1 and taking out the inner box 1 from the transport container 60, the frame 62 is folded as shown in FIG. 6 to send the inner box transport container 60 to the transport source again. It is placed in the space between the upper lid 61 and the lower lid 63, and the upper lid 61 is put on the lower lid 63 as shown in FIG. 7 so that the upper lid 61 and the lower lid 63 are not removed by the band 64.

  According to the above-described invention, since the flange portion 1a of the relatively strong inner box is placed in the lower lid 63 and the inner box 1 is supported by the frame body 62, the inner box having a relatively low strength. Since the upper cover 61 is disposed with a gap formed on the back surface of 1 and held by the cushion material 66, deformation or the like can be prevented with a simple configuration.

  In addition, since the deformation of the inner box 1 can be prevented, the inner box that has been subjected to the pretreatment can be transported satisfactorily while maintaining its shape, and a manufacturing base can be obtained overseas.

  Furthermore, the other element components 65 can be transported together using the opening space of the inner box 1, and the transportation cost can be greatly reduced. In this case, by providing the stopper 63 a on the lower lid 63, the element part 65 does not easily move due to vibration, and damage to the inner box 1 can be prevented.

  The above-described configuration is an embodiment of the present invention, and various changes can be made. For example, the shape, dimensions, material, and the like of the inner box transport container can be changed as appropriate according to the shape of the inner box and the number of uses.
