Description

  The present invention relates to a packaging material for transportation which is a composite of a paperboard box or the like and a molded receiving material.

  Conventionally, a pulp mold cushioning material opposed to the inner facing end face of the cardboard packaging box is disposed, and this is accommodated in one rectangular packaging box (hexahedral box) in a state where both ends of the packaged product are supported by the cushioning material. A packaging apparatus has been developed that closes the upper surface of the packaging box with an upper lid and packs the packaging box.

  However, if one packaged product is accommodated in one packaging box, the size of the box (size), strength and safety is limited and the packaging of large heavy weight packaged products is limited and limited. Not only is there a problem in the properties, but it is difficult to visually confirm the packaged product from the outside by customs or the like (for example, Patent Documents 1, 2, 3, and 4).

  An object of the present invention is to obtain a packaging material that is excellent in strong safety packaging such as large heavy products such as home appliances, and that is excellent in integration and detachability of a cushioning material and a paperboard box.

In order to achieve the above object, the present invention
Connect the trapezoidal upright outer end plates at both ends of the opposite inner and outer side plates and the bottom plate folded from a double folding line long edge of the rectangular bottom plate in the first and consecutively provided through a double folding line at both ends At each corner of a pair of paperboard boxes composed of opposed inner end plates , both end portions of the opposed inner and outer plates are extended to form a connection plate having a low height that intersects the side plates and the end plates . The inner end plate is folded inside, the molded receiving material is detachably fitted inside the opposing end plate and the connecting plate, and the receiving material is supported on the upper edge of the connecting plate, and the connection A packaging material provided with a protrusion that engages the outer surface of the plate,
Secondly, the packaging material according to the first invention, in which the side plate, the end plate and the connection plate are each formed of a multilayer plate,
Third, the packaging material according to the first or second invention, wherein the cardboard box is a cardboard box and the molded receiving material is a cushioning material formed by pulp mold,
Consists of.

  Therefore, a set of the paperboard or cardboard box is arranged oppositely on the upper and lower sides or both sides of the product to be packaged, and the upper and lower sides or both sides of the product are supported and fixed in a buffered state by opposing molding receiving materials.

  The molded receiving material is detachably fixed to the opposite end portion of the box by the engagement of the connecting plate and the protruding portion.

  In this state, the product to be packaged is exposed between the set of boxes disposed opposite to each other on the top and bottom or both sides and the molded receiving material in the set of the boxes, and can be visually confirmed from the outside.

  Of course, the upper and lower or both sides of the box are tightened by winding a synthetic resin band.

  Since the present invention is configured as described above, it can wrap large heavy products such as home appliances in a strong and safe manner, and the cushioning material is excellent in integration and detachability with the box, and the packaged product can be visually confirmed from the outside. There is no need to open or break the packaging material.

  As shown in FIG. 6 (a), opposed outer plates 2 'and 2' are provided on the long edge of the rectangular bottom plate 1 made of cardboard or corrugated board via parallel folding lines 1 'and 1', and the side plate 2 ' , 2 'are connected to the opposite inner side plates 2 ", 2" via double fold lines 2a, 2a, and folded from the double fold lines 2a, 2a to face the opposite inner and outer side plates 2 ", 2'. (B) As shown in the figure, the opposing side plates 2 and 2 are erected in parallel to each other.

  The opposite inner and outer plates 2 ", 2 'are extended at both ends, and cut lines 1", 1 "are formed along the parallel fold lines 1', 1 'from the extensions 2b, 2b. Rectangular cut spaces s, s and cut grooves 2c, 2c along the double fold lines 2a, 2a from the spaces s, s toward the extended ends are formed at both ends of the fold lines 2a, 2a.

  Trapezoidal standing outer end plates 3 'and 3' are connected to both ends of the rectangular bottom plate 1 via fold lines 1a and 1a, and opposite inner end plates 3 "and 2 'are connected to both ends via double fold lines 3a. 3 ”is connected continuously.

  Protruding edges 7, 7 are provided at the outer ends of the opposed inner end plates 3 ″, 3 ″, and long holes for inserting the protruding edges 7, 7 along the center portions of the both-end fold lines 1 a, 1 a of the rectangular bottom plate 1. 8 and 8 are drilled.

The parallel fold lines 1 ′ and 1 ′ of the cardboard or corrugated board formed in this way are folded by 90 degrees and the double fold lines 2a and 2a are folded by 180 degrees and formed at both ends of the opposed inner and outer plates 2 ″ and 2 ′. The space portions s, s are folded 45 degrees in the opposite direction from the first fold lines s ', s', and further, the second fold lines s ", s" are parallel to the first fold lines s ', s'. Fold 45 degrees in the opposite direction,
Further, the trapezoidal upright outer end plates 3 ', 3' stand upright from the fold lines 1a, 1a, and the opposite inner end plates 3 ", 3" from the double fold lines 3a, 3a from the double fold lines 3a, 3a. Folded 180 degrees inward, folded back to the inside of the extended portions 2b, 2b from the second fold lines s ", s", and the protruding edges 7, 7 were inserted into the elongated holes 8, 8 as shown in FIG. ) (B) and FIG. 6 (b) A pair of opposing end plates 3 and 3 and a box 4 made of paperboard or corrugated board can be formed.

At the four corners of the box 4, the height from the cut line 1 "to the space s is short, from the parallel fold lines 1 ', 1' to the double fold lines 2a, 2a, that is, the opposing side plates 2, 2 and A connection plate 5 is formed which is lower than the height of the opposed end plates 3 and 3 by ½ width of the space s .

  Each of the pair of boxes 4 and 4 thus formed has opposing inner end portions in contact with the opposing end plates 3 and 3, the connection plates 5 and 5, and the opposing side plates 2 and 2 so as to be freely detachable. Mating.

The receiving material 6 is a cushioning material formed by pulp mold,
Protruding portions 6 ′ and 6 ′ that engage with the outer surfaces of the connecting plates 5 and 5 are provided at both corners of the receiving member 6.

  The opposing side plates 2 and 2 and the connecting plates 5 and 5 of the boxes 4 and 4 thus formed are double-layered by paperboard or corrugated board, and the counter-end plates 3 and 3 are triple-layered (FIG. 6 (B)). ).

  Further, a synthetic resin packaging film 9 is brought into contact with the inner surface of the pair of boxes 4 and 4, that is, the inner surfaces of the bottom plate 1, the opposing side plates 2 and 2, and the molded receiving materials 6 and 6, and the television 9 and other large home appliances through the film 9 As shown in FIGS. 1 and 2, the lower end portion of the product 10 is inserted into the box 4 facing upward, and the lower surfaces 10 ′ and 10 ′ of the both ends of the product 10 are placed below the opposing inner surfaces of the molded receiving materials 6 and 6. The product 10 is supported on the receiving steps 6 "and 6", both side surfaces of the product 10 are supported by the opposed upright receiving surfaces 6a and 6a (FIGS. 1, 2 and 3), and both end surfaces of the product 10 are supported. It is supported by the upright receiving surfaces 6b and 6b.

  The upper end portion of the home appliance 10 is also inserted into the downward box 4 as shown in FIG. 1, the middle portion of the upper and lower boxes 4 and 4 exposes the product 10, and the exposed portion is the upper and lower synthetic resins. The packaging films 9 and 9 are heat-welded and coated.

  The upper and lower paperboard boxes 4 and 4 are fastened together by several synthetic resin bands 11 and conveyed.

  In addition, the unevenness | corrugation shown by 6c, 6c 'in FIG. 3 reinforces the shaping | molding receiving material 6, 6d is an upper edge flange and engages with the upper edge of the said box 4, and 6e is the shaping | molding receiving material 6.
