Description

  The present invention relates to a packaging structure for protecting a packaged body and improvement of the package.

In a corrugated cardboard tray box for a bottom used in a conventional outdoor unit of an air conditioner, etc., the flaps extended from the long side surface are bent at 90 degrees at four corners, and this and the short side surface are A tray box shape is formed by fixing by glue bonding or the like. Inside the tray box, foam foams for cushioning are mainly disposed at both short ends, and a convex part is provided on the bottom and short side parts of the foam foam for cushioning, and the bottom surface of the cardboard and A hole is provided in the short side surface and the like, and these are fitted and temporarily fixed without using an adhesive or the like.
In addition, the upper surface of the foam foam for cushioning is provided with a notch for fitting the mounting leg of the packaged body, and by placing the packaged body positioned thereby, depending on the weight of the product from above In combination with the above-described two temporary fixings, the final fixing is performed.
Also, various types of cardboard tray boxes have been put to practical use. (For example, see Patent Document 1)
Japanese Patent Laid-Open No. 10-194285 (paragraph numbers [0002] and [0003], FIGS. 5, 8, and 9)

  A conventional packaging structure for protecting a packaged body (such as an outdoor unit of an air conditioner) is configured as described above, so that the upper surface opening part of the cardboard tray box is inevitably opened to the outside during the box making operation. There is a problem that the foamed foam for cushioning that is fitted and temporarily fixed is detached from the corrugated cardboard tray box due to vibration and handling during transportation before the product is placed.

Further, in the structure of the corrugated cardboard tray box shown in the technical document 1, the reinforcing plate and the reinforcing column are formed by corrugated cardboard on the inner side of the four corners, so that the corners of the shock absorbing foam polystyrene are avoided from the reinforcing plate and the reinforcing column. There was a problem that it had to be installed in the shape.
The appearance of a packaging structure that solves these problems is strongly desired.
In view of the above, the present invention is a structure that is strong in vibration and handling during transportation and maintains the strength in the corner portion, and the corrugated cardboard tray box can be assembled without using wire punching, glue bonding, etc., and cost reduction In addition, an object of the present invention is to provide a packaging structure and a packaging body that can save labor in unpacking after use.

  The packaging structure according to the present invention is such that, in a cardboard tray box for a bottom surface of a packaging material disposed on a packaged body, the upper opening after boxing is made narrower than the area of the bottom surface, and at the time of transportation In order to prevent the shock-absorbing foam polystyrene from popping up and coming off due to vibrations, load handling, etc., the rising angles of the four side surfaces are made to be less than 90 degrees inward of the cardboard box. The inclined four side surfaces of the corrugated cardboard tray box are configured to press against the side surfaces of the shock-absorbing polystyrene foam and prevent the cardboard tray box from coming off.

  Further, in order to fix the inward inclination of the four side surfaces, a convex portion is provided at the tip of the flap portion extended from both ends of the short side surface, and a hole for fixing the insertion of the convex portion is provided in the long side surface portion. These are inserted and fitted. The projecting tip portion of the convex portion has a structure in which a return portion is provided so as not to come out of the fixing hole.

  The packaging structure according to the present invention prevents the cardboard tray box from opening outside the open top surface of the corrugated cardboard tray box, and the foamed foam for cushioning temporarily fixed by the fitting structure is used when transporting the product in a stage before placing the product. This solves problems such as detachment from the cardboard tray box due to vibration and cargo handling. In addition, the corrugated cardboard tray box is assembled without using wire punching, glue bonding, or the like, thereby reducing costs and saving labor for unpacking after use.

[Embodiment 1]
FIG. 1 is a perspective explanatory view of a packaging structure according to Embodiment 1 of the present invention.
FIG. 2 is a fitting explanatory view of the corrugated cardboard tray box and the shock-absorbing polystyrene foam according to the first embodiment.
FIG. 3 is a development view of the cardboard tray box according to the first embodiment.
In the figure, 1 is a corrugated cardboard tray box, 2 is a cushioning foamed polystyrene that protects the bottom surface of the packaged body, 3 is a convex part for fitting with the cardboard tray box provided on the foaming foam for cushioning, and 4 is a cushioning provided on the cardboard tray box Fitting holes with foamed polystyrene for use, 5 is a flap portion for fixing the tray box form, 6 is a folding ruled line, 11 is a long side surface portion, and 12 is a short side surface portion.

The first embodiment of the present invention will be described below with reference to FIGS.
In these figures, the rising angle θ is less than 90 degrees (70) so that the opening is narrowed with respect to the bottom surface portion, with the four side surfaces facing inward from the corrugated cardboard box by bending from a single corrugated board. The cardboard tray box 1 is configured to be fixed to the short side surface portion 12 by wire-bonding or glue bonding using the fixing flap 5 installed on the long side surface portion 11. At this time, the rising angle θ of the side surface portions 11 and 12 is bent so as to be determined by the inclination angles previously provided to the long and short side surface portions 11 and 12 in the four directions extracted by the punching die of the corrugated board. A ruled line 6 is inserted.
The rising angle θ is less than 90 degrees, preferably 70 degrees or more and 85 degrees or less. If it is 85 degrees or more, the tendency of the long side surface portion 11 to fall to the outside increases, and if it is less than 70 degrees, the degree of freedom of fitting with the expanded polystyrene 2 is greatly reduced. The degree of detachment of the cushioning foamed polystyrene 2 from the corrugated cardboard tray box is determined by the degree of fitting between them and the coefficient of friction, and the degree of fitting is preferably selected within a range that does not cause permanent deformation of the foamed polystyrene. The rising angles θ of the side portions in the four directions do not have to be the same, and there is no problem even if they are different within the above angle range.

  The shock-absorbing polystyrene foam 2 is disposed in parallel with both ends of the short side surface portion 12 inside the cardboard tray box 1. The upper opening of the cardboard tray box 1 is narrower than the bottom surface of the shock-absorbing foamed polystyrene 2, but due to the slight springiness of the cardboard, the upper opening is inserted while being expanded and placed. Further, the shock-absorbing foamed polystyrene 2 may be slightly different depending on the appearance shape of the package 100, but the basic structure is a rectangular parallelepiped having substantially the same width as the bottom side surface of the cardboard tray box 1 (corrugated cardboard tray box 1 The length direction of the bottom long side surface portion 11 is arbitrary, and the height direction is approximately the same as the length of the side surface portion of the cardboard tray box 1). A hole 4 is provided on the bottom surface of the corrugated cardboard, and this is used as the first fixing, and this is fixed by pressing the short side surface portion 12 of the corrugated cardboard tray box 1 and the foam foam 2 for buffering. The movement in the direction along the long side surface portion 11 is suppressed. Further, as the third and fourth fixations, the long side surface portion 11 is also symmetric with the two surfaces, and the movement in the direction along the short side surface portion 12 is suppressed by being pressed together. The And since the 2nd-4th side surface part has stood up so that it may become less than 90 degree | times inward, it becomes a form which pinches | interposes the side surface of the three directions of the foaming foam 2 for buffering, and, thereby, comes off upwards These can be prevented, and it is possible to fix them by simply fitting the shock-absorbing polystyrene foam 2 into the cardboard tray box 1 without using an adhesive or the like.

[Embodiment 2]
FIG. 4 is a perspective explanatory view of a packaging structure according to Embodiment 2 of the present invention.
FIG. 5 is a development view of a cardboard tray box according to Embodiment 2 of the present invention.
FIG. 6 is an enlarged view of the assembly of the insertion convex part 8 and the insertion hole part 9.
FIG. 7 is an overall view of a package body in which a package body (such as an outdoor unit of an air conditioner) is packed using the second embodiment of the present invention.
In the figure, 7 is a flap part for fixing the tray box form, 8 is a protrusion for insertion provided at the tip of the flap part 7 for fixing the tray box form, 81 is a return part of the insertion convex part, and 9 is an insert. Insertion hole portions 10 for the convex portions 10 are binding bands for binding the entire packaging structure, and 100 is a packaged body.

The second embodiment of the present invention will be described below with reference to the drawings.
FIG. 4 shows the corrugated cardboard tray box 1 according to Embodiment 1 of the present invention, in which the flap 7 with the short side surface portion 12 extended is further extended, the insertion convex portion 8 is provided at the tip, and the convex portion 8 is inserted and fixed. Holes 9 are provided at the relative positions of the long side surface portion 11. The convex part 8 has a shape with an inclined angle so that it can be easily inserted into the hole 9 at the time of assembly, and has a return part 81 to prevent it from coming off easily when inserted, Once inserted, the dimension of the return portion 81 is slightly longer than the length of the hole 9 so that the return portion 81 is caught by the edge of the hole 9. Further, the convex portion 8 is arranged at a position where the flap 7 is extended to a place where the buffering foam polystyrene 2 does not exist in the long side surface portion 11, and the hole 9 is also arranged at a position corresponding to this, so that the foaming foam polystyrene is provided. Even if it does not change the shape of 2 etc., it becomes a structure which does not inhibit the fitting to the corrugated cardboard tray box 1.

  Further, the flap 7 may be detached or slack due to an external action caused by physical distribution or cargo handling. However, in the final packaging form in which all the packages such as the package body 100 and the top surface portion are combined, the binding band 10 is held at the position where the binding band 10 is held down when the binding band 10 is circulated and fixed. By hanging on, it is possible to prevent the insertion convex portion 8 from being detached or slack.

  The embodiment of these inventions is not only an outdoor unit of an air conditioner, but also a cushioning material such as polystyrene foam 2 having the same width as the side surface portion 12 of the cardboard tray box is arranged in the cardboard tray box. It can be applied to anything, if any.
