Description

  The present invention relates to a product packaging tool for rectangular product packaging produced by processing a cardboard material.

In order to protect products such as preventing scratches, commercial and industrial products are generally shipped and transported in a state of being packed in a packaging box made of corrugated cardboard having cushioning properties. In particular, a product packing tool for a rectangular parallelepiped product (rectangular product) is often formed in a flat plate shape so that the product can be packed while being wrapped like a wrapping paper. The tabular products packing implement is, to be assembled into a box-like simplicity, corner or corner vicinity is cut, are cut and fold formation (e.g., see Patent Document 1).

  If such a flat product packing tool is used, the product packing tool can be folded and folded so as to wrap the product along the outer shape of the product, like a wrapping paper. By doing so, the gap space between the product and the packaging box can be made as small as possible so that the product can be packaged so as not to rattle and not bulky. Moreover, since it is flat, it is easier to form than a box-shaped one, and there is an advantage that a product packing tool can be manufactured at low cost.

Japanese Patent Laid-Open No. 11-105859

By the way, even if it is a flat product packing tool as described above, there may be a slight gap between the product and the product. Further, in order to enhance the protection by applying a pad material (buffer material, protective material) to the side end face or corner portion of the rectangular product, a gap space may be provided so that the pad material can be easily packed. Furthermore, in the case of packing a piece of furniture having different dimensional specifications, for example, different height dimensions, with a single type of product packing tool, there is naturally a gap space depending on the dimensions. Don't be.

  However, if such a pad material is prepared separately, the packaging cost will increase, and even if it is substituted with a handy one at the time of packing, an appropriate one may not be found, or if the pad material is processed and formed on site There is also a risk that the working efficiency is significantly lowered.

  The present invention has been proposed in view of such circumstances, and the purpose thereof is to efficiently package a rectangular product at low cost, and to easily prepare a pad material to be packed in the packaging. An object of the present invention is to provide a product packing tool that can ensure product protection.

In order to achieve the above object, a product packaging tool according to the present invention is a product packaging tool for rectangular product packaging manufactured by processing a cardboard material, wherein the rectangular product is a plate-like body, and the cardboard material is a rectangular shape. and none of the packaging component body provided with a bottom portion disposed in the center and side portions that projects continuously provided in each of the four sides of the bottom portion, of the cardboard material in order to form the packaging component body is configured obtained by cutting and separating the four corners four scraps each having a pad material made to deform bent, in a state that held against the pad material to the four corners of the rectangular product, the bottom surface of the packing device main body One side of the rectangular product is covered with a portion, and the other side of the rectangular product is covered by bending the four side surfaces of the packing tool body.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  Fig.1 (a) is a top view of the packing tool main body which is a structural member of the product packing tool concerning this embodiment, FIG.1 (b) is an enlarged plan view of the end material cut out in order to form a packing tool main body. is there. FIGS. 2A to 2D are views showing a procedure for generating a pad material, which is another component of the product packing tool. In addition, the product packing tool shown in this embodiment is intended for packing folding doors.

The packaging main body 10 which is the main component of the product packaging 1 is obtained by cutting the rectangular corrugated cardboard material 2 and separating the end materials 3 at the four corners by a forming method such as die cutting. It has a flat plate shape (see FIG. 1A).

  As will be described later, the packing body 10 is formed in a flat plate shape so that it can be assembled while wrapping a rectangular product like a wrapping paper, and a corner portion is cut off and a crease A is given. The fold A may be formed by a mark line by printing or the like, a perforation, or the like.

  As shown in FIG. 1A, a rectangular bottom surface portion 11 is disposed at the center of the packaging body 10. Each of the four sides of the bottom surface portion 11 is provided with a side surface portion 12 projectingly connected to the side surface portion 12, and a folded portion 13 that can be folded and used is continuously disposed. 14 is formed. In addition, it cannot be overemphasized that the shape, dimension, and structure of this packing implement main body 10 are formed so that it may correspond in general with the shape, dimension, classification, etc. of the folding door 30 (refer FIG. 4) which is a packing object.

  As shown in FIG. 1B, each end member 3 cut from the four corners of the corrugated cardboard material 2 has a substantially T-shape in which the horizontal piece 3a is longer than the vertical piece 3b.

  The cardboard material 2 is formed with a plurality of strip-shaped hollow portions 2 a (see FIG. 3) that are partitioned, but in the present embodiment, the hollow portion 2 a extends along the short direction of the cardboard material 2. Is formed. That is, the hollow portion 2 a is formed along the longitudinal direction of the horizontal piece portion 3 a of the end material 3.

The end material 3 is a material for forming the pad material 20 applied to the four corner portions 33 of the folding door 30 when the folding door 30 (see FIG. 4) in a folded state is packed with the packing body 10. It is. In order to make it easy to mold the pad material 20, a crease A is provided on the surface of the end material 3.

  The shape and structure of the pad material 20 will be described with reference to the formation procedure shown in FIGS. 2A to 2D and the side view shown in FIG.

  First, the T-shaped horizontal piece 3a of the end material 3 is folded in accordance with two lateral folds A in the vertical direction (the direction of the white arrow in FIG. 2A) to form a multilayer structure. (See FIGS. 2 (a), (b) and FIG. 3). At the time of folding, as described above, since the band-shaped hollow portion 2a is formed along the longitudinal direction of the horizontal piece portion 3a, it can be folded smoothly (see FIG. 3).

  Next, the T-shaped horizontal piece 3a having a multi-layer structure is bent and wound according to the four folds A to form a substantially cylindrical (quadrangular in the illustrated example) main body 21 (FIG. 2 (b) and (c)). Furthermore, the end portions of the overlapping horizontal piece portions 3a of the main body portion 21 are connected with an adhesive tape T (or adhesive or the like).

  In this state, the vertical piece 3 b of the end member 3 is in a state of being extended from one edge of the rectangular cylindrical main body 21, and this vertical piece 3 b constitutes the auxiliary piece 22 of the pad material 20.

  Then, from the edge of the auxiliary piece 22, a notch 22a is made to the middle in a direction substantially parallel to the horizontal piece 3a, and the notched piece is bent toward the main body 21 to form a bent piece 23 (FIG. 2 (c) and (d)).

  In this way, four pad materials 20 are formed.

  In this embodiment, the pad material 20 has a substantially cylindrical main body 21, an auxiliary piece 22, and a bent piece 23 formed by bending a part of the auxiliary piece 22, Needless to say, it is formed so as to match the shape, size, type, etc. of the object to be packed. For example, it is not always necessary to have a substantially cylindrical shape, and the bent piece 23 may not be provided.

  Moreover, you may form the main-body part 21 of the pad material 20 in a substantially cylindrical shape, without making it a multilayer structure. In addition, in order to form the main-body part 21 firmly, it is desirable to set it as a multilayer structure like the example of this figure.

  In the present embodiment, the width dimension of the auxiliary piece 22 of the pad material 20 (the vertical piece portion 3b of the end material 3) (that is, the dimension of one side of the main body portion 21 from which the auxiliary piece 22 is extended) is the packing target. It is substantially the same as the thickness dimension of the folding door 30 in the folded state.

  As described above, the pad material 20 is formed by using the end material 3 obtained by cutting and separating the cardboard material 2 in order to form the packaging body 10, so that the packaging cost can be reduced. Moreover, since the scrap 3 can be used without being discarded, it can contribute to resource saving.

  Further, since the pad material 20 is formed from the end material 3, it may be formed in advance when the packaging tool body 10 is formed. Therefore, it is not necessary to search for a familiar pad material at the packing site or to form a new pad material, and the packing work can be performed efficiently.

  Next, the packing mode of the folding door 30 by the packing tool body 10 and the four pad members 20 formed by the forming procedure shown in FIG. 2 will be described along the packing procedure shown in FIGS. In FIG. 4, the pad material 20 is shown in an enlarged manner.

  First, the folding door 30 is placed at the center of the bottom surface portion 11 of the packaging body 10 so that one surface of the folded folding door 30 (the outer surface of the one door plate 30 a) is covered with the packaging body 10. At this time, a slight gap space S is formed between the bottom door 11 and the folding door 30 at both ends in the longitudinal direction.

Next, the pad material 20 (the main body portion 21) is disposed in the gap space S formed outside the side end surface 31 in the longitudinal direction of the folding door 30 so as to be applied to each of the four corner portions 33 of the folding door 30. In the present embodiment, as shown in FIG. 5, the pad material 20 is applied over the entire height of the side end surfaces 31 and 32 in the corner portion 33 of the overlapped door plates 30 a, so that the pad material 20 is more than the end material 3. The four generated are used.

In addition, the pad material 20 corresponds to each of the four corner portions 33 of the folding door 30, and has different directions so that the folding piece 23 is inserted between the two door plates 30 a constituting the folding door 30. , Respectively.

Specifically, as shown in FIGS. 5 (a) and 5 (b), the folded piece 23 that protrudes in the lateral direction is inserted between the door plates 30 a, and the auxiliary piece 22 is side end face in the width direction of the folded door 30. The pad material 20 is disposed so that the opening of the main body 21 is assigned to the side end face 31 in the longitudinal direction of the folding door. The pad material 20 is disposed on the other corner portions 33 in the same procedure. In addition, in FIG. 5, the mounting | wearing aspect of the pad material 20 with respect to one corner part 33 of the side combined with the hinge 30b of the doorplate 30a is illustrated.

Thus, the pad material 20 is disposed at each of the four corner portions 33 of the folding door 30 so as to protect the corner portion 33. In particular, the continuous edge portion 33a of the two door plates 30a in the corner portion 33 of the two overlapping door plates 30a is hidden by the pad material 20 over its entire length.

  In addition, when wrapping the folding door 30 with a protective sheet (not shown), after laying the protective sheet on the bottom surface portion 11 in advance, placing the folding door 30 thereon, and disposing the pad material 20, The upper surface of the product may be wrapped with a protective sheet.

  And in the state which attached the pad material 20 to the folding door 30, the four side parts 12 and the folding | returning part 13 of the packing tool main body 10 are folded in order along the shape of the folding door 30, and it becomes the external shape of the folding door 30. A package body is formed (see FIG. 6).

  The folding order is not particularly limited. In FIG. 6, the side surface portion 12, the folded portion 13, and the folded piece 14 corresponding to the side end surface 32 side in the width direction of the folding door 30 are first folded, and then the side surface portion 12 corresponding to the side end surface 31 side in the longitudinal direction. The example which folded the folding | returning part 13 is shown.

  Thus, the side surface portion 12 of the packaging tool body 10 is applied to the side end surfaces 31 and 32 of the folding door 30, and the folded portion 13 is arranged on the upper surface of the folding door 30. In this example, the folded pieces 14 provided continuously on both side ends of the folded portion 13 are applied to the side end surface 31 in the longitudinal direction of the folding door 30, and further, a side surface portion provided continuously from the bottom surface portion 11. 12 is applied to overlap.

  And several places are fixed with the band B so that the folding | returning part 13 of the packing tool main body 10 folded on the upper surface of the folding door 30 may not open so that the packing tool main body 10 may not remove from the folding door 30.

In this way, the folding door 30 is packed in the packing body 10 with the corner portion 33 being applied by the pad material 20.

According to such a product packaging tool 1, since the four corner portions 33 of the most fragile folding door 30 are in the state where the pad material 20 is applied, the pad material 20 acts as a protective material, and the corner portion 33 is prevented from being scratched. In particular, since the continuous edge portion 33a of the two door plates 30a in the corner portion 33 of the two overlapping door plates 30a is reliably covered with the pad material 30, the edge portion 33a is hardly damaged.

  In addition, when the folded folding door 30 is leaned against a wall or the like, a load is applied to the lower end of the folding door 30 and the lower end surface is easily damaged. However, in the box in which the main body portion 21 of the pad material 20 is packed. Since it acts as a cushioning material like the leg portion, it is possible to reliably prevent damage to the lower end surface.

  Furthermore, since the pad material 20 is packed in the gap space S so as not to move the folding door 30 in the packing box formed by the packing tool body 10, rattling during transportation or the like can be prevented. Moreover, it can also prevent that the packaging box loses its shape.

  Furthermore, according to the structure of this embodiment, since the bending piece 23 for interposing between the door plates 30a is formed in the pad material 20, it can also prevent that the door plates 30a collide and rattle.

  In this embodiment, the example of the folding door 30 is shown as a rectangular product. However, a thick rectangular parallelepiped product may be used as a packaging target, and in that case, the packaging body and pad material having different shapes, dimensions, and structures may be used. Used.

  FIG. 7 is an explanatory diagram of a product packing tool for a rectangular product that is thicker than the folding door 30, FIG. 7 (a) is a plan view of the packing tool body, and FIG. 7 (b) is the packing tool body. It is a top view of eight end materials obtained at the time of formation of.

Packaging component body 10 includes a bottom portion 11, and continuously provided by four sides 12 to the bottom surface portion 11, becomes more and four folded portion 13 provided continuously on each side portions 12, four corner portions from cardboard material 2 Is obtained by removing

Further, the end material 3 has a rectangular shape, and is obtained by further cutting each of the removed four corner portions into two of the same shape and the same size.

  Each of these end materials 3 is formed into a multi-layer structure by bending along a crease A made in the longitudinal direction, and further folded along a crease A in the width direction to form a square cylinder, The pad material 20 is formed by bonding the end portions with the adhesive tape T. In addition, the pad material 20 of this embodiment consists only of the main-body part 21, and the auxiliary piece and the bending piece are not formed.

These eight pad materials 20 may be applied in the vicinity of the eight corners on the side end face side of the rectangular product (not shown in FIG. 7), and packed in the packing tool body 10 in that state. .

  As the packing tool main body 10 and the pad material 20 constituting the product packing tool 1, various shapes other than those shown in the above embodiment can be assumed. The packaging body 10 may have any shape as long as it has at least the bottom surface portion 11 and the four side surface portions 12, and the pad material 20 is cut from the corrugated cardboard material 2 to form the packaging material body 10. Any shape may be used as long as the end material 3 is bent and deformed. In addition, the pad material 20 does not need to use all the cut off end materials 3.
