Description

The present invention relates to an improvement of a packaging device for packaging a packaging object such as a home appliance or a gas appliance. In particular, the object of the present invention is to reinforce the ridge line portion when the width of the top portion is narrower than the bottom portion as a packaging object and a large space exists in a rectangular parallelepiped packaging box body.

For example, when transporting or storing products such as electrical equipment, various cushioning materials are stored in a cardboard box together with the equipment to prevent damage when the equipment body is scratched or dropped. . Generally, heavy equipment is placed on a bottom member with a cushioning material so that it can be easily packed and unpacked, covered with a cardboard box from above, and packed with a cushioning material on the top. The form is taken.

  In recent years, however, there are an increasing number of devices having a tapered front surface from the viewpoint of space saving or design. For this reason, since the generally used corrugated packaging material is a rectangular parallelepiped shape, a large space is generated above the interior of the packaging material, and this portion of the packaging material is easily damaged and functions as a protective material. Had the problem of lowering.

Although the purpose of the packaging material is mainly to protect the equipment to be stored, if the packaging material itself is deformed or damaged, the value of the product is significantly reduced even if the stored equipment has no problem. In addition, stability during storage and transportation is reduced, and other products may be adversely affected.

  Therefore, the present inventor has achieved the present invention as a result of intensive studies in view of the above problems, and the feature of the present invention is that in the packaging material for packaging the packaging object such as home appliances, the packaging object is A packaging box main body that is to be accommodated and has a length side flap and a width side flap extended on each of the four sides of the upper opening end, and a cushioning member disposed on both width side sides of the packaging box main body to protect the corners of the packaging object The pair of the width surface flaps is formed by pressing at least one of the length surface flaps folded in half so that the tip reaches the base by a fold line parallel to the side.

  Alternatively, in a packing material for packing a packaging target object such as a home appliance, a packaging box main body that accommodates the packaging target object and has a length side flap and a width side flap extended on four sides of the upper opening end, and the packaging A cushioning member that is disposed on both width sides of the box body and protects the corners of the packaging object, and is formed by bending the length surface of the packaging box body and the cushioning member by bending it into an L shape. A reinforcing member in which a reinforcing material interposed therebetween is extended to at least one end is provided below either the length surface flap or the width surface flap.

  Here, the “packaging box body” in the present specification is a cardboard member that accommodates and packs a packaging object such as a home appliance, and is surrounded by a length surface and a width surface provided opposite to each other. It has a structure in which four surfaces are formed and the top surface is covered with a length surface flap and a width surface flap that extend on the four sides of the upper opening end. As for the bottom surface, it is common to place an object to be packaged on a separate cardboard tray, but it may be formed by extending a length surface flap and a width surface flap on the four sides of the lower opening end.

  In the first invention of the present invention, at least one of the length surface flaps provided at the upper opening end is folded in two so that a fold line parallel to the side is provided and the tip reaches the base. And this is taped and packed in the state pressed down with the width | variety surface flap. Thereby, since the length surface flap which comprises a top surface becomes a double structure, and the edge part has reached the ridgeline part, the span of the space part in which the buffer member etc. do not exist in the ridgeline part inside of a packaging box is long. Even in this case, the pressure strength on the top surface side can be maintained.

  For example, it is useful in a packaging form in which the buffer member is disposed only on both width surfaces of the packaging box body and the length of the length surface in the side direction is longer than the width surface. In particular, when the width of the top surface of the packaging object is narrow, the packaging box body does not impair the cushioning function of the cushioning member even if the upper space of the packaging box body is large and the free length of the cushioning member is increased. Can improve the shape retention. Usually, the two length surface flaps facing each other are provided with a fold line and folded in half, but only the length surface flap on the side where the upper space is larger may be folded in half. In this case, you may make it overlap on the length surface flap which folded the other length surface flap into two.

  A reinforcing material that is inserted between the length surface of the packaging box body and the buffer member may be further extended to the long surface flap that is folded in half. Since this reinforcing material is bent from the base portion of the length surface flap and exists in an L shape, the strength of the ridge line portion can be further increased.

  The “buffer member” refers to a member having a buffer function for protecting the device by contacting the device. The structure, material, and shape of the buffer member are not particularly limited, and a molded product such as foamed plastic or pulp mold may be used, or may be formed of corrugated cardboard. Usually, a buffer member is provided in the two ridgeline parts which the top | upper surface and bottom face of a packaging target object mutually oppose. In the case of packing the object to be packaged on a separate tray, the cardboard extending from the tray body can be bent and formed.

The “reinforcing member” is a cardboard member provided over almost the entire top surface side of the packaging box main body in the second invention of the present invention, and is bent into an L shape and the length surface of the packaging box main body and the buffer member The reinforcing material interposed between the two is provided at at least one end. With this reinforcing member, it is possible to increase the strength from the top surface to the ridge line portion where the reinforcing material is provided, as in the first invention of the present invention. The reinforcing member is usually provided so as to be sandwiched between the width surface flap and the length surface flap, but may be placed directly on the buffer member. Moreover, you may extend the member which makes a L-shaped part double from the reinforcing material provided in the edge part.

  In the packaging device according to the present invention, the length surface flap is folded in half so that the tip reaches the base by a fold line parallel to the side. Alternatively, a reinforcing member having a reinforcing material which is bent in an L shape at at least one end portion and interposed between the length surface of the packaging box body and the buffer member is provided on the top surface side of the packaging box body. Thereby, the intensity | strength of the part in which the buffer member etc. in a top surface side ridgeline part does not exist can be raised.

In particular, when packaging a packaging object that creates a large space on the top side of the packaging box body, a large cushioning is required due to structural reasons, such as when the cushioning member cannot be provided in the space, or due to costs or post-processing. When a member cannot be provided, an extremely beneficial effect is obtained.

By increasing the strength from the top surface of the packaging box body to the ridge line on the top surface where no buffer member or the like is present, a predetermined strength is ensured with a small number of parts without depending on the costly buffer member.

  FIG. 1 is an example of a packaging apparatus 1 according to the first aspect of the present invention, and shows a state in which a dishwasher T having a shape with an inclined front surface is packed. The packaging device 1 has a structure in which a dishwasher / dryer T is placed on a cardboard tray 3 provided with a buffer member 2 and a packaging box body 4 is covered from above and packed. A cushioning member 2 made of polystyrene foam is further provided at the upper corner of the dishwasher T, and the upper opening is closed with a length surface flap 41 and a width surface flap 42 extending from the four sides of the upper end of the packaging box body 4 and taped. Pack it.

  In the present invention, as shown in the illustrated dishwasher T, the front surface is inclined, so that the packaging material having a larger internal space is protected in order to protect the packing material substantially in the center of the length surface flap 41 and parallel to the side. It is folded in two at a broken line 43. Thus, as shown in FIG. 2, when packed by the packaging device 1, not only the top surface of the packaging box body 4, but also the tip of the folded-up length surface flap 41 reaches the base, so the strength of the ridge line portion is high. Become. And it leads also to aiming at the protection of the buffer member 2 whose free length becomes long inevitably, and the function as a packing material can be improved.

The packaging box main body 4 has a structure shown in the blank sheet of FIG. 3A, and includes a length surface flap 41 and a length surface flap 41 respectively from one end of each length surface 44 and each width surface 45 constituting the peripheral surface of the rectangular parallelepiped. The width surface flap 42 is extended. The folding line provided at the substantially central portion of the length surface flap 41 is doubled as shown in the figure, thereby forming a surface orthogonal to the length surface flap 41 when bent, thereby increasing the surface pressure strength. . The cardboard tray 3 on which the dishwasher / dryer T is placed and packed has a structure in which a foamed cushioning member 2 is disposed at an opposed position inside as shown in FIG.

FIG. 4 is another example of the packaging device 1 according to the first invention, in which a reinforcing material 46 is extended at the tip of the length surface flap 41. The reinforcing material 46 is interposed between the length surface 44 of the packaging box body 4 and the buffer member 2, and can be further increased in strength at the ridge line portion by being bent in an L shape.

FIG. 5 is an example of the packaging device 11 according to the second invention of the present invention, and shows a state where the dishwasher T is packed. The packaging device 11 has a structure in which a reinforcing member 5 made of corrugated cardboard having a size covering almost the entire top surface of the packaging box body 4 is provided, and a reinforcing member 46 extending at one end is bent into an L shape. Then, it is interposed between the length surface 44 of the packaging box body 4 and the buffer member 2. The reinforcing member 5 of this example is placed on the upper surface of the width surface flap 42 and is provided so as to be sandwiched by the length surface flap 41 from above. By bending the reinforcing material 46 at the end into an L shape, the same strength as in the first and second embodiments described above can be obtained, and the number of parts increases, but the assembly is simple and the packaging work is facilitated. There are advantages.
