[First Embodiment]
With reference to FIG. 1 to FIG. 3, a packaging tool 1 according to a first embodiment of the present invention will be described. 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. FIG. 3 is an enlarged 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. The Z direction (direction perpendicular to the XY plane) may be referred to as the vertical direction (the direction 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-like member) 10 and a plurality of films 30. In this embodiment, the film 30 is cylindrical. A plurality of films 30 are wound on the plate 10. The packing tool 1 can pack a plurality of articles including a first article and a second article.

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

In addition, in FIG. 1, the unfolded state of the packing tool 1 is shown. The dimensions of the unpacked packing tool 1 are, for example, about 300 millimeters in the left-right direction and about 180 millimeters 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 an article assumed as a packing target, various uses, and the like.

As shown in FIG. 2, the plurality of films 30 includes an inner film 31 and an outer film 32. Through holes 300 are formed in the plurality of films 30. Specifically, a through hole 311 is formed in the inner film 31. In addition, a through hole 321 is formed in the outer film 32. Each of the through hole 311 and the through hole 321 extends parallel to the left-right direction (parallel to the X axis). The outer film 32 is located outside the inner film 31.

As shown in FIG. 1, the packaging tool 1 has two openings (opening 331 and opening 332). The opening 331 is formed by the inner film 31 and the plate 10. The opening 331 has two opening end portions 31a. The opening 332 is formed by the inner film 31 and the outer film 32. The opening 332 has two opening end portions 32a.

1 and 2, the plate 10 is provided with three fold lines (folds; streaks) 21, 23, and 24. That is, one parallel fold line 21 and two

cross fold lines

23 and 24 are formed on the plate 10. These fold lines 21, 23, and 24 are formed, for example, by pressing a so-called creasing roller or a creasing blade. The bend lines 21, 23, 24 may be perforated.

The parallel fold line 21 is arranged in parallel in the left-right direction (parallel to the X axis). That is, the parallel fold line 21 extends parallel to the direction in which the opening 331 and the opening 332 extend. The plate 10 can be easily bent with respect to the parallel fold line 21 so that both front and rear ends are displaced upward.

The cross fold line 23 is arranged in the vicinity of the right end portion of the plate 10 in parallel to the front-rear direction (parallel to the Y axis). That is, the cross folding line 23 extends in parallel to the direction intersecting the direction in which the opening 331 and the opening 332 extend. Further, the cross folding line 24 is disposed in the vicinity of the left end portion of the plate 10 in parallel in the front-rear direction. The plate 10 can be easily bent with respect to the cross fold line 23 so that the right end portion is displaced upward. The plate 10 can be easily bent with respect to the cross fold line 24 so that the left end portion is displaced upward.

In the present embodiment, as shown in FIG. 3, the plate 10 is formed by a front liner 19a, a back liner 19b, and a center core 19c. The front liner 19a and the back liner 19b are plate-shaped. The center core 19c is wavy. The

cross fold lines

23 and 24 are formed so as to be parallel to the streak direction (so-called paper width direction) of the wavy portion of the center core 19 c of the plate 10. Further, the parallel fold line 21 is formed so as to be orthogonal to the direction of the central core 19c. That is, the parallel folding line 21 is formed so as to be parallel to the so-called flow direction. Accordingly, the parallel fold line 21 is formed so as to cross the wavy portion of the center core 19c. Therefore, when the plate 10 is bent by the parallel fold line 21, the restoring force for returning the plate 10 to the unfolded state becomes relatively large.

Since the plate 10 is provided with the parallel fold lines 21 and the

cross fold lines

23 and 24, the plate 10 is partitioned as follows.

The section of the plate 10 will be described with reference to FIG. FIG. 4 is a plan view schematically showing the plate 10.

In FIG. 4, a part surrounded by various hatchings corresponds to one section here. In FIG. 4, the inner film 31 is indicated by a two-dot chain line, and the outer film 32 is indicated by a chain line. Moreover, the parallel fold line 21 and the

cross fold lines

23 and 24 are each shown with the dashed-dotted line. As shown in FIG. 4, the plate 10 is provided with four sections of a reference surface 11, a parallel bent surface 12, and two

cross-folded surfaces

15 and 16. An article 50 to be packed is disposed on the reference surface 11. The parallel bending surface 12 is adjacent to the reference surface 11. The article 50 to be packed may be disposed across the reference surface 11 and the parallel bent surface 12.

A parallel fold line 21 is disposed between the reference surface 11 and the parallel fold surface 12. In other words, the reference surface 11 and the parallel folding surface 12 are partitioned via the parallel folding line 21. The reference surface 11 is disposed on the front side of the plate 10, and the parallel bent surface 12 is disposed on the rear side of the plate 10. The cross-bending surfaces 15 and 16 are partitioned so as to be adjacent to the reference surface 11 and the parallel bending surface 12 via the

cross-bending lines

23 and 24, respectively. The cross-bending surface 15 is a portion on the right side of the cross-bending line 23 in the plate 10. The cross-bending surface 16 is a portion on the left side of the plate 10 with respect to the cross-bending line 24. In other words, the reference surface 11 is a portion in front of the parallel fold line 21 and is located between the cross fold line 23 and the cross fold line 24. In addition, the parallel folding surface 12 is a site behind the parallel folding line 21 and between the cross folding line 23 and the cross folding line 24.

In the plate 10, the parallel folding surface 12 and the rear part of the

cross-bending surfaces

15 and 16 are parallel folding lines 21 with respect to the reference surface 11 and the front part of the

cross-bending surfaces

15 and 16. It can be bent.

The open end 31a is hung on the cross-bending surfaces 15 and 16. Further, the opening end portion 32 a is hung on the cross-bending 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 edge portions 10m of the plate 10 is linear. The reference surface 11 has a rectangular shape. The parallel folding surface 12 has a rectangular shape.

Referring back to FIG. 1, the film 30 is disposed 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 of the film 30 (direction orthogonal to the circumferential direction) is the left-right direction. In other words, the film 30 is wound around the plate 10 so that the parallel fold line 21 penetrates the inside of the cylinder formed by the film 30.

The inner film 31 and the outer film 32 may be attached to the plate 10 by various methods. For example, the inner film 31 is attached to the plate 10 by passing the plate 10 through the inner film 31 formed in a ring shape in advance. Further, the outer film 32 is attached to the outer side of the inner film 31 with respect to the plate 10 by passing the plate 10 to which the inner film 31 is attached into the outer film 32 formed in a ring shape in advance. Further, for example, the inner film 31 is attached to the plate 10 by winding the film around the plate 10 once by using a band wrapping machine or the like and bonding the films together. After the inner film 31 is attached to the plate 10, the film is further wound around the plate 10 to which the inner film 31 is attached using a band wrapping machine or the like, and the films are adhered to each other, whereby the outer film is adhered. 32 is attached to the outside of the inner film 31 with respect to the plate 10. With the film 30 attached to the plate 10, the plate 10 can be bent along the

folding lines

21, 23, and 24.

In the present embodiment, the parallel folding line 21 is offset to the rear side of the front and rear center of the plate 10. That is, the parallel fold line 21 is located at a position shifted from the center of the plate 10. The area of the reference surface 11 is larger than the area of the parallel bent surface 12.

The following effects are produced by the parallel folding 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 folding line 21, when the packing tool 1 is folded on a substantially horizontal table, the reference surface 11 is on the table. It is possible to easily maintain the state of being installed in the Therefore, the packing operation can be easily performed without using a dedicated jig or the like.

Next, a method for packing a plurality of articles 50 using the packing tool 1 will be described with reference to FIG. FIG. 5 is a schematic diagram illustrating a packing method using the packing tool 1 according to the present embodiment. In the present embodiment, the plurality of articles 50 includes a first article 51 and a second article 52. The height of the second article 52 is higher than the height of the first article 51.

As shown in FIG. 5 (b), the packaging tool 1 is folded (hereinafter referred to as a folded state) by folding the parallel folding surface 12 with respect to the reference surface 11 at a parallel folding line 21. There is). When the packing tool 1 is in a bent state, the first article 51 can be disposed in the gap A between the inner film 31 and the upper surface of the plate 10 (here, the reference surface 11). That is, in the folded state, the length of the path connecting the front end portion, the rear end portion of the plate 10 and the fold portion of the parallel folding line 21 portion with a straight line is smaller than that in the expanded state in a side view. In the bent state, the difference between this path and the circumference of the inner film 31 increases. For this reason, a gap A is formed between the parallel folded surface 12 and the reference surface 11 and the inner film 31. The first article 51 to be packed can be placed in the gap A.

The larger the bending angle (the smaller the angle formed between the parallel folding surface 12 and the reference surface 11), the greater the difference between the path length and the circumference of the inner film 31. The space between the reference 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 first article 51 can be disposed in the gap A.

Moreover, as shown in FIG.5 (c), when the packing tool 1 is a bending state, the 2nd article | item 52 can be arrange | positioned in the clearance gap B between the inner side film 31 and the outer side film 32. FIG. That is, in the folded state, the length of the path connecting the front end portion, the rear end portion of the plate 10 and the fold portion of the parallel folding line 21 portion with a straight line is smaller than that in the expanded state in a side view. In the bent state, the difference between this path and the circumferential length of the outer film 32 increases. For this reason, a space is formed between the parallel folding surface 12 and the reference surface 11 and the outer film 32. Therefore, a gap B is formed between the parallel folding surface 12 and the reference surface 11, and the inner film 31 and the outer film 32. The second article 52 to be packed can be disposed in the gap B.

FIG. 5A shows a cross section taken along line VA-VA in FIG. In FIG. 5, packing using the packing tool 1 is performed in such a manner that steps S11, S12, S13, and S14 are followed in order from the top to the bottom.

As shown in FIG. 5 (a), the packing tool 1 is prepared (S11; preparing step). The unpacked packing tool 1 has a flat plate shape. From this state, as indicated by an upward arrow in the figure, the plate 10 is bent at the parallel fold line 21 to bring the parallel fold surface 12 closer to the reference surface 11 to be in a fold state (bending step).

Next, as shown in FIG. 5B, the first article 51 is disposed in the gap A between the reference surface 11 and the inner film 31 in a state where the plate 10 is bent (S12; first). Article placement step).

Next, as shown in FIG.5 (c), the 2nd article | item 52 is arrange | positioned in the clearance gap B between the inner side film 31 and the outer side film 32 in the state by which the board 10 was bent (S13; 2nd). Article placement step). Here, the second article 52 is arranged in front of the first article 51.

Thereafter, as shown by the downward arrow in FIG. 5 (d), the parallel bent surface 12 is developed with respect to the reference surface 11 to be in a developed state (S14). Then, the inner film 31 is stretched while being in contact with the upper part of the first article 51. As a result, the first article 51 is pressed against the plate 10. Further, the outer film 32 is stretched while being in contact with the upper part of the second article 52 (deployment step).

The packaging tool 1 will be further described with reference to FIGS. FIG. 6 is a perspective view showing the packing device 1 that has been packed and opened. FIG. 7 is a perspective view showing a state where the cross-bending surfaces 15 and 16 are raised.

The packing tool 1 is stretched in a state in which the inner film 31 is in contact with the first article 51 as the folding state of the parallel bending surface 12 (folding surface) with respect to the reference surface 11 changes. One article 51 is pressed against the plate 10. Specifically, as shown in FIG. 6, when the unfolding step is performed, the front end portion and the rear end portion of the plate 10, the fold portion of the parallel folding line 21, and the upper portion of the first article 51 are straightened in a side view. When the first article 51 is arranged, the length of the route connected with the line becomes larger than the initial deployed state. Therefore, the inner film 31 is stretched while slightly extending in a state of being in contact with the upper portion of the first article 51. Therefore, the first article 51 is pressed against the plate 10 by the inner film 31.

Furthermore, the packing tool 1 is stretched in a state in which the outer film 32 is in contact with the second article 52 as the bending state of the parallel bending surface 12 (the bending surface) with respect to the reference surface 11 changes. The second article 52 is configured to be pressed against the plate 10. Specifically, when the unfolding step is performed, the length of the path connecting the front end portion, the rear end portion of the plate 10, the fold portion of the parallel fold line 21 portion, and the upper portion of the second article 52 in a side view is straight. By arranging the second article 52, it becomes larger than the initial deployed state. Therefore, the outer film 32 is stretched while being slightly stretched while being in contact with the upper part of the second article 52. Therefore, the second article 52 is pressed against the plate 10 by the outer film 32.

Further, the packing tool 1 is configured such that the inner film 31 is pressed against the plate 10 by the second article 52 as the folding state of the parallel folding surface 12 (folded surface) with respect to the reference surface 11 changes. Has been. Since the inner film 31 is pressed against the plate 10 by the second article 52, the gap A between the parallel folding surface 12 and the reference surface 11 and the inner film 31 is removed from the packing device in which the film is wound in a single layer. Can also be narrowed. Therefore, the inner film 31 is stretched while slightly extending in a state of being in contact with the upper portion of the first article 51. Therefore, the first article 51 is pressed against the plate 10 by the inner film 31.

Here, in this embodiment, when the unfolding step is performed as described above, the

cross-folded surfaces

15 and 16 are raised by bending the

cross-folded lines

23 and 24 with respect to the reference surface 11. Can be. Thereby, the parallel folding surface 12 can be developed with respect to the reference surface 11, whereby the inner film 31 and the outer film 32 can be stretched. In addition, after performing an expansion | deployment step, you may raise the cross-bending surfaces 15 and 16 (startup step).

As shown in FIG. 7, since the

cross fold lines

23 and 24 cross the parallel fold line 21 on the plate 10, when the cross fold surfaces 15 and 16 are bent at the

cross fold lines

23 and 24, the plate 10 is And held in a state of being developed at the portion of the reference surface 11 and the parallel bent surface 12 (while being expanded so that the parallel bent surface 12 is substantially parallel to the reference surface 11). . In other words, the cross-bending surfaces 15 and 16 cannot be bent unless the reference surface 11 and the parallel bending surface 12 are in a substantially parallel state. In the present embodiment, the two

cross-bending surfaces

15 and 16 are provided via the two

cross-bending lines

23 and 24 that do not intersect with each other on the plate 10. , 16 are bent and brought into a raised state, the state in which the plate 10 is unfolded at the reference plane 11 and the parallel bent plane 12 is reliably maintained.

The package 80 will be described with reference to FIGS. FIG. 8 is an exploded perspective view of the package 80. FIG. 9 is a view showing the packing body 80 in a state where the packing tool 1 is housed in the outer box 70. FIG. 10 is a side sectional view showing the packing body 80.

As shown in FIGS. 8 and 9, the packing body 80 includes a packing tool 1 and an outer box 70. The packaging tool 1 is stored in the outer box 70 in a state where the cross-bending surfaces 15 and 16 are bent substantially perpendicularly to the reference surface 11. In other words, the dimension of the outer box 70 is set so that the packaging tool 1 in a state in which the cross-bending surfaces 15 and 16 are bent in this way is stored exactly. The packaging tool 1 is stored in the outer box 70 in a state in which the cross-bending surfaces 15 and 16 are bent with respect to the reference surface 11, so that the

cross-bending surfaces

15 and 16 are with respect to the reference surface 11. The folded state is maintained. Therefore, the state in which the film 30 is stretched is maintained, and the article 50 is reliably held at a fixed position on the plate 10.

The outer box 70 is, for example, a general cardboard box. In the state shown in FIG. 9, the upper cover of the outer box 70 is open. When the upper lid of the outer box 70 is closed, a substantially rectangular parallelepiped package 80 is completed.

FIG. 10 shows a cross section parallel to the XZ plane of the packaging body 80 in a state where the upper and lower lids of the outer box 70 are closed. As shown in FIG. 10, in the present embodiment, the bottom of the packing tool 1, that is, the reference surface 11 and the parallel bending surface 12, and the cross-folding surface 15 in the state where the packing tool 1 is stored in the outer box 70. , 16 are in contact with the inner surface of the outer box 70. In particular, the bottom portion 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-bending 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 raised state) of the

cross-bending surfaces

15 and 16 from the

cross-bending lines

23 and 24 shown by h1 in FIG. 8 and the outer box 70 shown by h2 in FIG. Are substantially equal to each other.

Thus, the outer box 70 is maintained in the vertical direction by the cross-bending surfaces 15 and 16, and the packing body 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, the article 50 can be firmly fixed even if vibration or an external force is applied to the package 80 during transportation or the package 80 is tilted. Note that 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-bending 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.

The cross-bending surfaces 15 and 16 are bent upward, and the upper ends of the

cross-bending surfaces

15 and 16 are located above the first article 51 and the second article 52. . That is, the state where the upper surface of the outer box 70 and the article 50 are separated is maintained. Therefore, for example, when the user unpacks the package 80, even if a sharp tool such as a knife is used to open the lid on the upper side of the outer box 70, the tool and the article 50 come into contact with each other. Is prevented and the article 50 is protected.

In addition, as the board 10 of the packing tool 1, it is preferable to use a cushioning material such as a corrugated cardboard having a certain thickness. Thereby, 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 more reliably protected. 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 inner film 31 is stretched in contact with the first article 51 as the bending state of the bending surface with respect to the reference surface 11 changes. Thus, the first article 51 is pressed against the plate 10 and the second article 52 is pressed against the plate-like member by being stretched while the outer film 32 is in contact with the second article 52. . Therefore, both the first article 51 and the second article 52 can be fixed to the plate 10 with the film 30 stretched. As a result, the plurality of articles 50 can be easily fixed and packed.

Also, the inner film 31 is configured to be pressed against the plate 10 by the second article 52 as the bending state of the bending surface with respect to the reference surface 11 changes. Therefore, the gap between the reference surface 11 and the inner film 31 can be reduced. Therefore, both the first article 51 and the second article 52 can be fixed to the plate 10 with the film 30 stretched. As a result, the plurality of articles 50 can be easily fixed and packed.

Further, in the packing tool 1, the article 50 can be held in a fixed position by placing the article 50 with the plate 10 bent and placing the article 10 again in the unfolded state. Therefore, the article 50 can be easily packed. Even after the plate 10 is once bent, it generates a restoring force to return to the natural state close to the unfolded state. Therefore, no complicated procedure is required to stretch the film 30, and the plate 10 can be easily set in the unfolded state.

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

In the first embodiment, the packing tool 1 can maintain the state in which the article 50 is held more reliably by bringing the two

cross-bending surfaces

15 and 16 into a raised state.

When unpacking, the cross-bending surfaces 15 and 16 may be returned to the original state and the plate 10 may be changed from the unfolded state to the folded state by the reverse procedure of packing. Thereby, the tension | tensile_strength of the film 30 can be eased and the articles | goods 50 can be removed easily. The packaging process does not include irreversible processes such as heat shrinking the film or using an adhesive. Therefore, packing and unpacking can be easily performed in this way. In addition, it is economical because the packing tool 1 once used for packing can be reused to pack another article 50. No adhesive or the like is used for 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, each of the opening end portion 31 a of the inner film 31 and the opening end portion 32 a of the outer film 32 hangs on the cross-bending surfaces 15 and 16. Therefore, when the

cross-bending surfaces

15 and 16 are bent with respect to the reference surface 11, the portions near the opening end portion 31 a and the opening end portion 32 a are also cross-folded lines 23 together with the

cross-bending surfaces

15 and 16. , 24. Thereby, a space surrounded by the reference surface 11 and the parallel bent surface 12 of the plate 10 and the film 30 is formed. Since the airtightness of the space can be maintained to some extent, it is possible to prevent the dust 50 from adhering to the article 50 arranged in the space with a simple configuration.
