Special Table No. 9-501128

However, with the packing tool described in Patent Document 1, it is difficult to easily fix and pack a short (thin) article. For example, when packing a short (thin) article, the gap between the film and the plate-shaped member is large, so that the short article may not be fixed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a packing tool and a packing method capable of easily fixing and packing a short article.

The packing tool according to the present invention is used for packing an article. The packing tool includes a film and a plate-shaped member. The film is attached to the plate-shaped member. The film and the plate-shaped member form an opening having two opening ends. The plate-shaped member has a base portion and a pressing portion. The holding portion is arranged on the base portion. The holding portion is covered with the film. The base portion has a reference surface and a bent surface. The bent surface is adjacent to the reference surface and can be bent. The holding portion has a base end and a tip end. The holding portion can be bent with respect to the base portion via the base end. The article can be placed in the gap between the base portion and the film.

In a certain embodiment, as the bent state of the bent surface with respect to the reference surface changes, the film is stretched in a state of being in contact with the tip of the holding portion, so that the holding portion is brought into contact with the article. The article is pressed against the base by contacting the upper surface of the article and pressing one end of the upper surface of the article, and the film faces the one end of the upper surface of the article. It is configured to be in contact with at least a portion of the end.

In certain embodiments, the direction from the proximal end to the distal end is along the direction in which the film is pulled.

In certain embodiments, the holding portion is arranged on the reference plane.

In certain embodiments, the base end is located off-center of the base portion.

In certain embodiments, the distance from the proximal end to the distal end varies depending on the position of the proximal end.

In certain embodiments, the angle defined by the reference plane and the film is greater than the angle defined by the top surface of the article and the film in a cross-sectional view along the direction in which the tip extends.

In certain embodiments, there are a plurality of the holding portions.

In certain embodiments, the plurality of pressing portions have different directions from the proximal end to the distal end.

In certain embodiments, the distances from the base end to the tip of the plurality of holding portions are different.

In certain embodiments, the proximal ends of the plurality of retainers are located in a straight line.

In certain embodiments, the plate-like member further comprises a bending line. The bent surface can be bent through the bending line. The bending line includes a parallel bending line extending parallel to the direction in which the opening extends. The bent surface has a parallel bent surface that can be bent adjacent to the reference surface via the parallel bent line. The article can be placed in the gap between the base portion and the film in a state where the parallel bent surface is bent with respect to the reference surface. With the article placed in the gap between the base and the film, as the parallel bent surface unfolds with respect to the reference surface, the film moves to the tip of the holding portion. The article is pressed against the base portion by contacting the pressing portion with the upper surface of the article and pressing one end of the upper surface of the article by being stretched in contact with the article. The film is configured to be in contact with at least a portion of the top surface of the article that faces the one end.

In certain embodiments, the parallel bending line is located off-center of the base portion.

In certain embodiments, the base is partitioned by two parallel bending lines that do not intersect each other on the base. The base portion has one reference surface and two parallel bending surfaces adjacent to the reference surface via one of the parallel bending lines, respectively.

In certain embodiments, the plate-like member further comprises a bending line. The bent surface can be bent through the bending line. The bending line includes a crossing bending line extending in parallel with the direction in which the opening extends. The bent surface has a cross-folded surface that is adjacent to the reference surface and can be bent via the cross-folded line. With the article placed in the gap between the base portion and the film, the cross-folded surface is bent from a state where the cross-folded surface is flush with the reference surface via the cross-folded line. As a result, the film is stretched in contact with the tip of the holding portion, so that the holding portion comes into contact with the upper surface of the article and presses one end of the upper surface of the article. The article is pressed against the base and the film is configured to come into contact with at least a portion of the top surface of the article facing the one end.

In certain embodiments, the open end hangs on the cross-bent surface.

In certain embodiments, the cross-folding surfaces are provided on the base with two sections defined by each of the two non-intersecting cross-fold lines.

In certain embodiments, the film is a stretchable film.

In certain embodiments, the film is tubular.

The packing method according to the present invention is a packing method for packing an article using a packing tool. The packing tool includes a film and a plate-shaped member. The film is attached to the plate-shaped member. The plate-shaped member has a base portion, a pressing portion, and a bent surface. The holding portion is arranged on the base portion.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals and the description is not repeated.

Hereinafter, the packaging tool according to the embodiment of the present invention will be described.

The packing tool is composed of a combination of a film and, for example, a corrugated cardboard plate-shaped member. The plate-shaped member has a base portion, a pressing portion, and a bending line. The packing tool can fix the article in a fixed position by pressing the article against the plate-shaped member by the pressing portion and the film. The article can be placed in the gap that extends between the ground plane of the plate-shaped member and the film in the state where the plate-shaped member is bent. As the bent state of the plate-shaped member changes, the film can be stretched and the article can be fixed by the pressing portion and the film.

The packing tool has a simple structure in which a film is attached to a plate-shaped member. Packing tools can be easily manufactured. The packing tool can also be manufactured by attaching a film to a plate-shaped member and fixing the films to each other.

By using the packing tool, manual packing can be easily performed. The packing tool can also be used, for example, when a large number of articles are continuously packed in a packing line. Thereby, packing in the packing line can be easily performed.

[First Embodiment]
The packing tool 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a packing tool 1 according to a first embodiment of the present invention. FIG. 2 is an exploded perspective view of the packing tool 1 according to the first embodiment.

In the following description, the X-axis direction of the coordinates shown in FIG. 1 is the left-right direction (the direction that is positive on the X-axis when viewed from the origin is the right direction), and the Y-axis direction is the front-back direction (the Y-axis is positive when viewed from the origin). The direction is the rear direction), and the Z-axis direction (the direction perpendicular to the XY plane) is the vertical direction (the direction that is positive on the Z-axis when viewed from the origin is the upward direction).

As shown in FIG. 1, the packing tool 1 includes a plate (an example of a plate-shaped member) 10 and a film 30. In this embodiment, the film 30 has a tubular shape. A film 30 is wound around the plate 10. The packing tool 1 can pack an article.

In the present embodiment, the plate 10 is made of, for example, a single corrugated cardboard having a thickness of about 5 mm. The film 30 is, for example, a film made of polyethylene and having elasticity (flexibility). The film 30 is colorless and transparent, but is not limited to this, and may be so-called translucent, opaque, or colored.

Note that FIG. 1 shows the unfolded state of the packing tool 1. The dimensions of the packing tool 1 in the unfolded state are, for example, about 300 mm in the left-right direction and about 180 mm in the front-rear direction. The dimensions of the packing tool 1 are not limited to this, and are set according to the size of the article assumed to be packed and various uses.

The plate 10 has a base portion 18, a pressing portion 40, and three bending lines (creases; streaks) 21, 23, and 24.

The base portion 18 has a flat plate shape. The base portion 18 is partitioned via the bending lines 21, 23, 24. Specifically, the base portion 18 has a reference surface 11 and a bending surface (parallel bending surface 12 and cross bending surfaces 15 and 16). The section of the base portion 18 will be described later with reference to FIG.

The pressing portion 40 has a base end 41, a tip end 42, an upper surface 43, and a lower surface 44. The holding portion 40 has a substantially rectangular shape. The base end 41 is linear. Both ends of the tip 42 are arcuate. The pressing portion 40 can be bent with respect to the base portion 18 via the base end 41. That is, the pressing portion 40 can rotate in the direction D1 about the base end 41. The pressing portion 40 is covered with a film 30.

As shown in FIG. 2, a through hole 300 is formed in the film 30. The through hole 300 extends parallel to the left-right direction (parallel to the X-axis).

As shown in FIG. 1, the packing tool 1 is formed with an opening 33. The opening 33 is formed by the film 30 and the plate 10. The opening 33 has two end portions 30a.

As shown in FIGS. 1 and 2, the plate 10 is provided with three bending lines (creases; streaks) 21, 23, and 24. That is, one parallel bending line 21 and two cross bending lines 23 and 24 are formed on the plate 10. These bending lines 21, 23, and 24 are formed, for example, by pressing a so-called reinforced roller or reinforced blade. Perforations may be performed on the folding lines 21, 23, and 24.

The parallel bending lines 21 are arranged parallel to the left-right direction (parallel to the X-axis). That is, the parallel bending line 21 extends parallel to the direction in which the opening 33 extends. The plate 10 can be easily bent with respect to the parallel bending line 21 so that both front and rear ends are displaced upward.

The cross-bending line 23 is arranged parallel to the front-rear direction (parallel to the Y-axis) at a position near the right end portion of the plate 10. That is, the cross bending line 23 extends parallel to the direction in which the opening 33 extends. Further, the cross bending line 24 is arranged parallel to the front-rear direction at a position near the left end portion of the plate 10. The plate 10 can be easily bent so that the right end portion of the cross bending line 23 is displaced upward. The plate 10 can be easily bent so that the left end portion of the cross bending line 24 is displaced upward.

The plate 10 is further provided with a pressing portion 40. A crease is formed in the base end 41 by pressing a so-called reinforced roller or reinforced blade. The holding portion 40 is formed by forming a notch in the plate 10 leaving the base end 41. The base end 41 may be perforated. An opening 48 is formed in the plate 10. The opening 48 corresponds to the shape of the holding portion 40. Therefore, the plate 10 can be flattened by inserting the pressing portion 40 into the opening 48. As a result, it is possible to pack the product without using the holding portion 40. In addition, the space for storing the packing tool 1 can be reduced. The pressing portion 40 is not provided by forming a notch in the plate 10, but may be provided by attaching another plate to the plate 10.

Since the plate 10 is provided with the parallel bending lines 21 and the cross bending lines 23 and 24, the plate 10 is partitioned as follows.

The section of the base portion 18 will be described with reference to FIG. FIG. 3 is a plan view schematically showing the plate 10.

In FIG. 3, the portion surrounded by various hatchings corresponds to one section referred to here. In FIG. 3, the film 30 is shown by an alternate long and short dash line. Further, the parallel bending line 21 and the cross bending lines 23 and 24 are indicated by alternate long and short dash lines, respectively. As shown in FIG. 3, the base portion 18 is provided with four sections, that is, a reference surface 11, a parallel bending surface 12, and two intersecting bending surfaces 15 and 16. The article 50 to be packed is arranged on the reference surface 11. The parallel bending surface 12 is adjacent to the reference surface 11.

A parallel bending line 21 is arranged between the reference surface 11 and the parallel bending surface 12. In other words, the reference surface 11 and the parallel bending surface 12 are partitioned by the parallel bending line 21. The reference surface 11 is arranged on the front side of the base portion 18, and the parallel bending surface 12 is arranged on the rear side of the base portion 18. The cross-folded surfaces 15 and 16 are partitioned via the cross-folded lines 23 and 24 so as to be adjacent to the reference surface 11 and the parallel bent surface 12, respectively. The cross-folding surface 15 is a portion of the base portion 18 on the right side of the cross-bending line 23. The cross-folding surface 16 is a portion of the base portion 18 on the left side of the cross-folding line 24. In other words, the reference surface 11 is a portion in front of the parallel bending line 21 and is a portion between the cross bending line 23 and the cross bending line 24. Further, the parallel bending surface 12 is a portion behind the parallel bending line 21 and is a portion between the cross bending line 23 and the cross bending line 24.

The pressing portion 40 is arranged on the base portion 18. In the present embodiment, the pressing portion 40 is arranged on the reference surface 11. The base end 41 is parallel to the parallel bending line 21. The direction from the base end 41 to the tip end 42 intersects in the direction in which the opening 33 extends. In the present embodiment, the direction from the base end 41 to the tip end 42 is orthogonal to the direction in which the opening 33 extends (X-axis direction). The pressing portion 40 can be bent with respect to the base portion 18 via the base end 41.

In the plate 10, the parallel bending surface 12 and the portion behind the cross bending surfaces 15 and 16 are parallel bending lines 21 with respect to the reference surface 11 and the portion in front of the cross bending surfaces 15 and 16. It can be folded.

The open end portion 30a hangs on the cross-bent surfaces 15 and 16. In other words, the length of the film 30 (the length of the cylinder) is longer than the width of the reference surface 11 in the left-right direction or the width of the parallel bent surface 12 in the left-right direction.

Each of the pair of edges 10 m of the plate 10 is linear. The reference surface 11 has a rectangular shape. The parallel bending surface 12 has a rectangular shape.

Returning to FIG. 1, the film 30 is arranged so as to mainly surround the reference surface 11 and the parallel bent surface 12 of the plate 10. The film 30 is arranged so that the width direction (direction orthogonal to the circumferential direction) of the film 30 is the left-right direction. In other words, the film 30 is wound around the plate 10 so that the parallel bending wire 21 penetrates the inside of the cylinder formed by the film 30.

The film 30 may be attached to the plate 10 by various methods. For example, the film 30 is attached to the plate 10 by passing the plate 10 through the film 30 formed in an annular shape in advance. Further, for example, the film 30 is attached to the plate 10 by winding the film around the plate 10 once using a band wrapping machine or the like and adhering the films to each other. With the film 30 attached to the plate 10, the plate 10 can be bent at the bending lines 21, 23, 24, respectively.

In the present embodiment, the parallel bending line 21 is offset to the rear side of the front-rear center of the base portion 18. That is, the parallel bending line 21 is located at a position deviated from the center of the base portion 18. The area of the reference surface 11 is larger than the area of the parallel bent surface 12.

The following effect is produced by the parallel bending line 21 being offset to the rear side. That is, since the reference surface 11 is wide and the center of gravity of the packing tool 1 is in front of the parallel bending line 21, the reference surface 11 is on the table when the packing tool 1 is bent on a substantially horizontal table or the like. It is possible to easily maintain the state of being installed in the like. Therefore, the packing work can be easily performed without using a dedicated jig or the like.

Next, a method of packing the article 50 using the packing tool 1 will be described with reference to FIG. FIG. 4 is a schematic view showing a packing method using the packing tool 1 according to the present embodiment. 4 (a) to 4 (c) show the cross section taken along line IV-IV of FIG. In FIG. 4C, the angle θ1 is the angle defined by the reference surface 11 and the film 30, and the angle θ2 is the angle defined by the upper surface 53 of the article 50 and the film 30. In this embodiment, the article 50 is a relatively short (thin) article.

As shown in FIG. 4B, the packing tool 1 is in a bent state (hereinafter referred to as a bent state) by bending the parallel bending surface 12 with respect to the reference surface 11 at the parallel bending line 21. There is). When the packing tool 1 is in the bent state, the article 50 can be arranged in the gap A between the film 30 and the upper surface (here, the reference surface 11) of the base portion 18. That is, in the bent state, the length of the path connecting the front end portion, the rear end portion, and the crease portion of the parallel bending line 21 with a straight line is smaller than that in the unfolded state in the side view. In the bent state, the difference between this path and the peripheral length of the film 30 becomes large. Therefore, a gap A is formed between the parallel bending surface 12 and the reference surface 11 and the film 30. The article 50 to be packed can be arranged in this gap A.

The larger the bending angle (the smaller the angle formed by the parallel bending surface 12 and the reference surface 11), the larger the difference between the length of the path and the peripheral length of the film 30, but the parallel bending surface 12 and the reference surface 12 and the reference surface. The space between the surface 11 and the surface 11 is narrowed. Therefore, the parallel bending surface 12 may be bent with respect to the reference surface 11 to an appropriate angle at which the article 50 can be arranged in the gap A.

A method of packing the article 50 using the packing tool 1 will be further described with reference to FIGS. 4 (a) to 4 (c) showing the cross section of the cross section taken along the line IV-IV of FIG. In FIG. 4, packing using the packing tool 1 is performed by following steps S11, S12, and S13 in order from top to bottom.

As shown in FIG. 4A, the packing tool 1 is prepared (S11; step to prepare). The unfolded packing tool 1 has a flat plate shape. From this state, as shown by the upward arrow in the figure, the plate 10 is bent at the parallel bending line 21 to bring the parallel bending surface 12 closer to the reference surface 11 to bring it into a bending state (folding step).

Next, as shown in FIG. 4B, the article 50 is arranged in the gap A between the reference surface 11 and the film 30 in a state where the plate 10 is bent (S12; article arrangement step).

After that, as shown by the downward arrow in FIG. 4C, the parallel bending surface 12 is unfolded with respect to the reference surface 11 to bring it into the unfolded state (S13). Then, the film 30 is stretched in contact with the tip 42 of the pressing portion 40. Therefore, the pressing portion 40 comes into contact with the upper surface 53 of the article 50 and presses one end 54 of the upper surface 53 of the article 50. As a result, the article 50 is pressed against the base portion 18. Further, the film 30 is stretched in contact with at least a part of the end portion 55 of the upper surface 53 of the article 50. As a result, the article 50 is pressed against the base portion 18 (deployment step). The end 55 faces one end 54. In the present embodiment, the direction D2 from the base end 41 to the tip end 42 is along the direction in which the film 30 is pulled (Y-axis direction).

In the packing method of the present embodiment, the film 30 is stretched in contact with the tip 42 of the pressing portion 40 in the unfolding step. Therefore, the contact point between the film 30 and the tip 42 is located above the article 50. Therefore, the angle θ2 can be increased. As a result, the film 30 comes into contact with the end 55. The angle θ1 is larger than the angle θ2 in the cross-sectional view along the direction in which the tip 42 of the pressing portion 40 extends.

The packing tool 1 will be further described with reference to FIGS. 5 to 6. FIG. 5 is a perspective view showing the packing tool 1 which has been packed and is in the unfolded state. FIG. 6 is a perspective view showing a state in which the cross-bent surfaces 15 and 16 are raised.

The packing tool 1 is stretched with the film 30 in contact with the tip 42 of the pressing portion 40 as the bent state of the parallel bent surface 12 (bent surface) with respect to the reference surface 11 changes. The pressing portion 40 is configured to come into contact with the upper surface 53 of the article 50 and press one end 54 of the upper surface 53 of the article 50 so that the article 50 is pressed against the base portion 18. Specifically, as shown in FIG. 5, when the unfolding step is performed, the front end portion, the rear end portion, the crease portion of the parallel bending line 21 portion, and the tip 42 of the holding portion 40 are straight lines in the side view. The length of the path connected by is larger than the initial unfolded state due to the arrangement of the article 50. Therefore, the film 30 is stretched while being slightly stretched in a state of being in contact with the tip 42 of the pressing portion 40. Therefore, when the film 30 presses the pressing portion 40, the pressing portion 40 comes into contact with the upper surface 53 of the article 50 and presses one end 54 of the upper surface 53 of the article 50. As a result, the article 50 is pressed against the base portion 18.

Further, in the packing tool 1, the film 30 faces one end 54 of the upper surface 53 of the article 50 as the bent state of the parallel bent surface 12 (bent surface) with respect to the reference surface 11 changes. It is configured to be in contact with at least a portion of the end 55. Therefore, the article 50 can be fixed to the plate 10 with the film 30 stretched.

Here, in the present embodiment, when the unfolding step is performed as described above, the cross-folding surfaces 15 and 16 are bent with respect to the reference surface 11 at the cross-folding lines 23 and 24 to stand up. Can be. As a result, the parallel bending surface 12 can be developed with respect to the reference surface 11, whereby the film 30 can be stretched. After performing the unfolding step, the intersecting bent surfaces 15 and 16 may be raised (starting step).

As shown in FIG. 6, since the cross bending lines 23 and 24 intersect the parallel bending lines 21 on the plate 10, when the cross bending surfaces 15 and 16 are bent at the cross bending lines 23 and 24, the plate 10 is formed. , It is held in the unfolded state at the portion between the reference surface 11 and the parallel bending surface 12 (the parallel bending surface 12 remains unfolded so as to be substantially parallel to the reference surface 11). .. In other words, the intersecting bent surfaces 15 and 16 cannot be bent unless the reference surface 11 and the parallel bent surface 12 are in a state of being substantially parallel to each other. In the present embodiment, since the two cross-folding surfaces 15 and 16 are provided via the two cross-folding lines 23 and 24 that do not intersect each other on the plate 10, the both cross-folding surfaces 15 By bending 16 and 16 to bring them into an upright state, the state in which the plate 10 is unfolded at the portion between the reference surface 11 and the parallel bent surface 12 is reliably maintained.

The package 80 will be described with reference to FIGS. 7 to 9. FIG. 7 is an exploded perspective view of the package 80. FIG. 8 is a diagram showing a packing body 80 in a state where the packing tool 1 is housed in the outer box 70. FIG. 9 is a side sectional view showing the package 80.

As shown in FIGS. 7 and 8, the packing body 80 includes a packing tool 1 and an outer box 70. The packing tool 1 is housed in the outer box 70 in a state where the cross-bent surfaces 15 and 16 are bent substantially perpendicular to the reference surface 11. In other words, the dimensions of the outer box 70 are set so that the packing tool 1 in the state where the cross-folded surfaces 15 and 16 are bent in this way can be accommodated exactly. Since the packing tool 1 is housed in the outer box 70 in a state where the cross-folded surfaces 15 and 16 are bent with respect to the reference surface 11, the cross-folded surfaces 15 and 16 are housed with respect to the reference surface 11. The folded state is maintained. Therefore, the stretched state of the film 30 is maintained, and the article 50 is securely held in place on the plate 10.

The outer box 70 is, for example, a general corrugated cardboard box. In the state shown in FIG. 8, the upper lid of the outer box 70 is open. When the upper lid of the outer box 70 is closed, the substantially rectangular parallelepiped packing body 80 is completed.

FIG. 9 shows a cross section of the package 80 in a state where the upper and lower lids of the outer box 70 are closed, parallel to the XZ plane. As shown in FIG. 9, in the present embodiment, with the packing tool 1 housed in the outer box 70, the bottom portion of the packing tool 1, that is, the reference surface 11, the parallel bending surface 12, and the cross-folding surface 15 , 16 is in contact with the inner surface of the outer box 70. In particular, the bottom of the packing tool 1 is in contact with the bottom surface of the inner surface of the outer box 70, and the upper ends of the cross-bent surfaces 15 and 16 are in contact with the inner surface of the upper surface of the outer box 70. That is, the width dimension (height dimension in the rising state) of the cross-folding surfaces 15 and 16 shown by h1 in FIG. 7 from the cross-folding lines 23 and 24 and the outer box 70 shown by h2 in FIG. The height dimension of is set to be substantially equal.

As a result, the outer box 70 is maintained in a state of being supported in the vertical direction by the cross-bent surfaces 15 and 16, and the package 80 becomes sturdy. Further, the position of the packing tool 1 is fixed inside the outer box 70 without using an adhesive or the like. Therefore, even if vibration or an external force is applied to the package 80 during transportation or the like, or the package 80 is tilted, the article 50 can be firmly fixed. The bottom of the packing tool 1 may be close to the bottom surface of the outer box 70, and the upper ends of the cross-bent surfaces 15 and 16 may be close to the top surface of the outer box 70. Even in this case, the same effect can be obtained.

Further, the cross-bent surfaces 15 and 16 are bent upward, and the upper ends of the cross-bent surfaces 15 and 16 are located above the article 50. That is, the state in which the upper surface of the outer box 70 and the article 50 are separated from each other is maintained. Therefore, for example, when the user unpacks the packing body 80, even if a sharp tool such as a knife is used to open the upper lid of the outer box 70, the tool and the article 50 come into contact with each other. This is prevented and the article 50 is protected.

As the plate 10 of the packing tool 1, it is preferable to use a cushioning material such as corrugated cardboard having a certain thickness. As a result, even if vibration or an external force is applied to the package 80, the magnitude of the impact transmitted to the article 50 can be reduced, and the article 50 can be protected more reliably. Further, the thicker the plate 10, the greater the restoring force for returning from the bent state to the natural state close to the unfolded state, so that the article 50 can be easily fixed.

As described above, in the first embodiment, the film 30 is stretched in contact with the tip 42 of the pressing portion 40 as the bent state of the bent surface with respect to the reference surface 11 changes. As a result, the pressing portion 40 comes into contact with the upper surface 53 of the article 50 and presses one end 54 of the upper surface 53 of the article 50, whereby the article 50 is pressed against the base portion 18, and the film 30 presses the upper surface of the article 50. It is configured to be in contact with at least a part of the end 55 facing the one end 54 of the 53. Therefore, the article 50 can be fixed to the plate 10 with the film 30 stretched while pressing the article 50 with the pressing portion 40. As a result, the short (thin) article 50 can be easily fixed and packed.

Further, in the packing tool 1, the article 50 can be held in a fixed position by arranging the article 50 in the bent state of the plate 10 and putting the plate 10 in the unfolded state again. Therefore, the article 50 can be easily packed. Even after the plate 10 is once bent, it generates a restoring force that tries to return to a natural state close to the unfolded state. Therefore, a complicated procedure is not required to stretch the film 30, and the plate 10 can be easily put into the unfolded state.

The packing tool 1 has a simple structure in which the plate 10 and the film 30 are combined. Therefore, it is not necessary to use a device that consumes a large amount of energy or a large-scale device for fixing the article 50, and the cost required for packaging can be reduced.

In the first embodiment, the packing tool 1 can more reliably maintain the state in which the article 50 is held by setting the two cross-bent surfaces 15 and 16 in the upright state.

At the time of unpacking, the cross-folded surfaces 15 and 16 may be returned to their original positions in the reverse procedure of packing, and the plate 10 may be changed from the unfolded state to the bent state. As a result, the tension of the film 30 can be relaxed and the article 50 can be easily removed. The packaging process does not include irreversible processes such as heat shrinking the film or using an adhesive. Therefore, it can be easily packed and unpacked in this way. Further, the packing tool 1 once used for packing can be reused to pack another article 50, which is economical. No adhesive or the like is used in the combination of the film 30 and the plate 10. Therefore, for example, even if only the film 30 is damaged, it can be reused as the packing tool 1 by replacing it with a new film 30.

Further, the open end portion 30a of the film 30 hangs on the cross-bent surfaces 15 and 16. Therefore, when the cross-folding surfaces 15 and 16 are bent with respect to the reference surface 11, the portion near the opening end 30a is also bent along with the cross-folding surfaces 15 and 16 at the cross-folding lines 23 and 24. .. As a result, a space surrounded by the reference surface 11 and the parallel bending surface 12 of the plate 10 and the film 30 is formed. Since the airtightness of this space can be maintained to a certain extent, it is possible to prevent large dust or the like from adhering to the articles 50 arranged in the space with a simple configuration.

As shown in FIG. 11, the base portion 18 has two pressing portions 40a and 40b. Therefore, the packing tool 1 can pack two articles 50. Further, the directions D3 and the direction D4 are facing in opposite directions. Therefore, the two articles 50 can be arranged at positions that do not interfere with each other. As a result, it is possible to prevent the two articles 50 from colliding with each other during transportation.

As shown in FIG. 12, since the cross bending lines 23 and 24 intersect the parallel bending lines 21 on the plate 10, when the cross bending surfaces 15 and 16 are bent at the cross bending lines 23 and 24, the plate 10 is formed. , Hold in the unfolded state at the portion between the reference surface 11 and the parallel bending surface 12 (the parallel bending surfaces 12 and 13 remain unfolded so as to be substantially parallel to the reference surface 11).

The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 24). However, the present invention is not limited to the above-described embodiment, and can be implemented in various aspects without departing from the gist of the present invention (for example, (1) to (8) shown below). The drawings are schematically shown mainly for each component for easy understanding, and the thickness, length, number, etc. of each component shown are different from the actual ones for the convenience of drawing creation. .. Further, the material, shape, dimensions, etc. of each component shown in the above embodiment are merely examples, and are not particularly limited, and various changes can be made without substantially deviating from the effects of the present invention. be.

(1) The material of the plate or film is not limited to the above-described embodiment. In addition to corrugated cardboard, thick paper may be used as the board. Further, the plate is not limited to paper, and may be made of resin such as polyethylene or rubber. When the plate is made of rubber, when the plate is in the unfolded state, it is possible to apply tension to the film by the repulsive force of the plate. The plate may be a plate-like member that can be bent and then redeployed. The film is not limited to polyethylene, and may be made of rubber. Alternatively, the material is not limited to resin such as polyethylene or rubber, and may be made of fiber such as cloth or paper. The film may or may not have elasticity. When the plate is in the unfolded state, the film is preferably stretchable so that tension is applied to the film.

(2) The dimensions of the plate and the circumference of the film can be changed as appropriate according to the articles to be packed. The plate is not limited to a rectangle, and may be a triangle or a pentagon or more. Alternatively, the plate may have a shape in which a notch is provided in a rectangular plate. FIG. 25A is a perspective view showing a packing tool 1 according to a modified example of the present invention. FIG. 25B is a plan view schematically showing the packing tool 1 according to the modified example of the present invention. In FIG. 25B, the length d4 indicates the length of the pressing portion 40 along the X-axis direction. The length d5 indicates the length of the article 50 along the X-axis direction. The length d6 indicates the length of the film 30 along the X-axis direction. The length d7 indicates the length of the notch 14 along the X-axis direction. The length d8 indicates the length from the cross-folding line 23 to the cross-folding line 24. The length d9 indicates the length from the tip 42 of the pressing portion 40 to the end of the plate 10. The length d10 indicates the length from the article 50 to the end of the plate 10. Since the packing tool 1 has the same configuration as the packing tool 1 according to the first embodiment except that the plate 10 is provided with the notch 14, the overlapping portion will be omitted.

As shown in FIGS. 25 (a) and 25 (b), the plate 10 is provided with a notch 14. The notch 14 has a rectangular shape. The corners of the notch 14 may be rounded. The length d7 of the notch 14 is preferably the length d4 or more and the length d8 or less of the pressing portion 40. The length d6 of the film 30 is preferably the length d4 or more of the pressing portion 40 and the length d7 or less of the notch 14. In this embodiment, the length d6 and the length d7 are substantially the same. The length d7 of the notch 14 is preferably equal to or greater than the length d5 of the article 50. When packing the article 50 with the packing tool 1, in order to stretch the film 30 to fix the article 50, it is preferable that the article 50 is arranged close to the end of the plate 10. The plate 10 is provided with a notch 14. Therefore, the length d9 from the tip 42 of the pressing portion 40 to the end of the plate 10 can be shortened. That is, the length d10 from the article 50 to the end of the plate 10 can be shortened. Therefore, the article 50 can be arranged close to the end of the plate 10 without changing the width and length of the plate 10. Since it is not necessary to change the width and length of the plate 10, an outer box 70 (see FIG. 8) having a specified size can be used. Further, since the plate 10 is provided with the notch 14, the peripheral length of the film 30 can be shortened. As a result, the amount of film 30 used can be suppressed. Further, by shortening the peripheral length of the film 30, the tensioning force of the film 30 can be increased.

The plate 10 may be provided with two notches 14. FIG. 26 is a plan view schematically showing the packing tool 1 according to the modified example of the present invention. Since the packing tool 1 has the same configuration as the packing tool 1 shown in FIGS. 25 (a) and 25 (b) except that the plate 10 is provided with two notches 14, the overlapping portion is provided. Omits the explanation. The plate 10 is provided with a notch 14a and a notch 14b. The notch 14b is provided on the parallel bending surface 12. The notch 14b is preferably provided behind the parallel bending line 21. In the packing tool 1, the plate 10 is provided with two notches 14. Therefore, the peripheral length of the film 30 can be further shortened as compared with the packing tool 1 shown in FIGS. 25 (a) and 25 (b). As a result, the amount of the film 30 used can be suppressed, and the tensioning force of the film 30 can be increased.

Further, the peripheral length of the film can be appropriately set within a range in which the article can be arranged when the plate is in the bent state and then the film is in the unfolded state so that tension is applied to the film. Further, the shape of the film is not limited to the band shape, but may be a mesh shape. Alternatively, the shape of the film is not limited to a flat shape, and may have irregularities such as a bubble wrap.

(3) The plate 10 is formed by a front liner 19a, a back liner 19b, and a core 19c, but the present invention is not limited thereto. The plate does not have a core 19c and may be formed of a single plate-shaped member.

(4) Instead of the stretchable film, a tubular member may be used. A plurality of films may be arranged side by side in the longitudinal direction of the parallel bending line.

(5) The outer box is not limited to the one made of corrugated cardboard as described above, and various forms can be used. For example, a thin article may be fixed to a plate by using the packing tool 1 of the above-described embodiment, and then put in an outer bag such as an envelope and sealed to form a packing body. .. In addition, various articles can be packed in various forms by using the packing tool 1.

(6) In the packing tool 1 described with reference to FIGS. 1 to 9, the parallel bending line 21 is located at a position deviated from the center of the plate 10, but the present invention is not limited thereto. For example, the parallel bending line 21 may be located at the center of the plate 10. In this case, the area of the reference surface 11 and the area of the parallel bending surface 12 are equal to each other.

(7) In the packing tool 1 described with reference to FIGS. 13 to 15, the article 50 is fixed by raising the cross-bent surfaces 15 and 16 with respect to the reference surface 11, that is, bending them upward. However, the present invention is not limited to this. For example, the article 50 may be fixed by lowering the cross-bent surfaces 15 and 16 with respect to the reference surface 11, that is, by bending downward. When the article 50 is packed using the outer box 70 as in the packing body 80 shown in FIGS. 7 and 8, the cross-bent surfaces 15 and 16 are bent downward to be between the plate 10 and the outer box 70.
