Description

The present invention relates to a packaging mount.

Packaging containers assembled from corrugated cardboard sheets are used to pack goods such as products purchased at online shops. Among them, as a packaging container for relatively small and thin articles such as CDs, DVDs, and paperback books, a pedestal panel and a packing sheet having a lid panel connected to the pedestal panel via a folding line are known ( See Patent No. 5736080).

A packaging container using this packing sheet is formed by placing an article on a pedestal panel, folding the lid panel along a folding line of the pedestal panel, and covering it with a shrinkable film.

Japanese Patent No. 5736080

In the conventional packing sheet, the lid panel has a plurality of rows of slits composed of a plurality of slits, and the lid panel can be deformed based on the shape of the article at the time of packing. Due to this deformation, the packing container using the packing sheet has an excellent article holding function.

On the other hand, when the article to be packed becomes thicker, in the conventional packing sheet, a gap is likely to occur on the side perpendicular to the folding line, particularly at the corner. This gap may cause damage to the article during transportation and may reduce the confidentiality of the contents.

The present invention has been made in view of such circumstances, and when packing an article using a shrinkable film, a packaging mount that is unlikely to have gaps at corners regardless of the thickness of the article to be packed. Providing is an issue.

The wrapping mount according to one aspect of the present invention is a wrapping mount used when packing an article using a shrinkable film, and is a pair of pedestal panels that are foldably connected so as to sandwich the article. The pair of pedestal panels face each other with a rectangular body, a connecting flap extending from one side edge of the body and connecting the tip edges to each other, and the one side edge of the body. An end flap extending from the side edge, a pair of side flaps extending from the other pair of opposite side edges of the main body, and a pair of tongue pieces extending from both ends of the pair of side flaps. The tongue piece has a straight portion extending from the base end side of the side flap, and an arc portion connecting the tip of the straight portion and the tip of the side flap.

In the packaging mount of the present invention, when an article is packed using the shrinkable film, gaps are unlikely to occur at the corners regardless of the thickness of the article to be packed.

[Explanation of Embodiment of the present invention]
First, embodiments of the present invention will be listed and described.

The wrapping mount according to one aspect of the present invention is a wrapping mount used when packing an article using a shrinkable film, and is a pair of pedestal panels that are foldably connected so as to sandwich the article. The pair of pedestal panels face each other with a rectangular body, a connecting flap extending from one side edge of the body and connecting the tip edges to each other, and the one side edge of the body. An end flap extending from the side edge, a pair of side flaps extending from the other pair of opposite side edges of the main body, and a pair of tongue pieces extending from both ends of the pair of side flaps. The tongue piece has a straight portion extending from the base end side of the side flap, and an arc portion connecting the tip of the straight portion and the tip of the side flap.

In the packaging mount, when the article is packed using the shrinkable film, the pair of side flaps have their tips bent and abutted against each other, so that the gap between the pair of pedestal panels can be covered. At that time, the pair of tongue pieces extending from both ends of the pair of side flaps are further bent. At this time, the straight portion of the tongue piece closes the gap between the connecting flap and the side edge of the end flap, and is bent so that the arc portions of the facing tongue pieces are abutted against each other. It is possible to cover the gap generated at the corner of the. Further, since the pair of tongue pieces can cover the gaps formed at the corners regardless of the bending angle of the side flaps due to the arc portion of the tongue piece, the packaging mount depends on the thickness of the article to be packed. When packing articles using a shrinkable film, gaps are unlikely to occur at the corners.

It is sufficient that other tongue pieces do not extend from both ends of the connecting flap and the end flap. By preventing the other tongue pieces from extending from both ends of the connecting flap and the end flap in this way, when the article is packed using the shrinkable film, the tongue pieces interfere with each other and a gap is created at the corner. It can be prevented from occurring.

It is preferable that the side edges of the connecting flap and the end flap are inclined inward toward the tip end side in the extending direction. By inclining the side edges of the connection flap and the end flap inward toward the tip side in the extension direction in this way, the straight portion of the tongue piece is on the pair side in a state where the pair of side flaps are bent. The pair of side flaps tend to bend when packing the article with the shrinkable film because it comes into contact with the edges.

It is preferable that the main body has a bending guide portion formed of a bending guide line on the surface side sandwiching the article so that the main body bends following the article. By providing the bending guide portion in the main body so as to bend following the article in this way, when the article is packed using the shrinkable film, the pair of pedestal panels are deformed based on the shape of the article. Therefore, the article holding function can be enhanced.

The bending guide portion passes through a plurality of square first bending guide lines whose vertices are concentric with the center of the main body and whose vertices are on the diagonal line of the main body, and the closest vertices of each of the plurality of first bending guide lines. , It is preferable to have four linear second bending guide lines extending toward the apex side of the main body. In general, many articles are square, and by configuring the bending guide portion as described above, the deformation of the pedestal panel can easily follow the shape of the article.

Here, the "shrinkable film" is a general term for films that shrink when heat is applied.

[Details of Embodiment of the present invention]
Hereinafter, the packaging mount according to the embodiment of the present invention will be described with reference to the drawings as appropriate.

The wrapping mount shown in FIG. 1 is a wrapping mount used when packing an article using a shrinkable film. The packaging mount includes a pair of pedestal panels 1 that are foldably connected so as to sandwich the article.

The packaging mount can be composed of, for example, one corrugated cardboard sheet. The corrugated cardboard sheet may be not only one in which both sides of one core are sandwiched between a pair of liners, but also a so-called double flute in which the cores are sandwiched between three liners. It may be a so-called single-sided corrugated cardboard in which a liner is attached only to one side of the core.

The lower limit of the thickness of the corrugated cardboard sheet is preferably 1 mm from the viewpoint of strength. On the other hand, the upper limit of the thickness of the corrugated cardboard sheet is not particularly limited, but is preferably 3 mm from the viewpoint of ease of assembly into a package.

The pair of pedestal panels 1 face the rectangular main body 10, the connecting flap 11 extending from one side edge 10a of the main body 10 and connecting the tip edges to each other, and the one side edge 10a of the main body 10. An end flap 12 extending from the side edge 10b, a pair of side flaps 13 extending from the other pair of opposite side edges 10c of the main body 10, and a pair extending from both ends of the pair of side flaps 13. Tongue piece 14 and.

<Main body>
When the pair of pedestal panels 1 are folded back, the main body 10 comes into contact with the article to be packed and sandwiches it.

The size of the main body 10 is appropriately selected according to the size of the article to be packed. For example, one side edge 10a is 20 cm or more and 50 cm or less, and the other side edge 10c extending perpendicular to the one side edge 10a. Can be 15 cm or more and 40 cm or less.

The main body 10 has a bending guide portion 15 formed of a bending guide line on the surface side sandwiching the article so as to bend following the article. By providing the bending guide portion 15 so as to bend following the article in the main body 10 in this way, when the article is packed using the shrinkable film, the pair of pedestal panels 1 are deformed based on the shape of the article. Therefore, the article holding function can be enhanced. The bending guide line can be composed of, for example, a ruled line formed by pressing a muscle.

In the present embodiment, as shown in FIG. 1, the bending guide portion 15 is concentric with the center of the main body 10 and has two square first bending guide lines 15a having vertices on the diagonal line of the main body 10. It has four linear second bending guide lines 15b that pass through the nearest vertices of the first bending guide lines 15a and extend toward the apex side of the main body 10. Further, the bending guide portion 15 has a pair of third bending guide lines 15c connecting the pair of long sides of the outer first bending guide line 15a facing each other. The third bending guide line 15c is combined with a part of the long side of the first bending guide line 15a to form a square. In general, many articles are square, and by configuring the bending guide portion 15 as described above, the deformation of the pedestal panel 1 can easily follow the shape of the article.

The bending guide portion 15 shown here is an example, and depending on the shape of the article to be packed, for example, a bending guide portion 15 having no third bending guide wire 15c or a bending guiding portion 15 having another configuration is adopted. You can also do it. Further, although the pair of main bodies 10 shown in FIG. 1 both have a bending guide portion 15, they may be provided only on one main body 10.

<Connection flap and end flap>
The tip edges of the two connecting flaps 11 provided on the pair of pedestal panels 1 are connected to each other. A folding line 1a is formed at the boundary line between the pair of connecting flaps 11.

Examples of the folding line 1a include ruled lines, perforations, half-cut lines, and combinations thereof. Among them, as the wrapping line 1a, as shown in FIG. 1, a plurality of ruled lines 1b composed of two parallel straight lines and arranged at equal intervals at both ends and the center of the wrapping line 1a, and the plurality of ruled lines 1b. It is preferable that the lead ruled line is arranged between them and has a plurality of perforations 1c having a Y-shaped notch toward the ends of the two parallel straight lines at the ends. By forming the ruled line 1b with two parallel straight lines in this way, the ruled line 1b can be bent in two steps, so that the repulsive force when the ruled line 1b is folded back can be reduced, and the article can be easily packed. Further, the perforation 1c is provided with a Y-shaped notch toward the end of the two parallel straight lines of the ruled line 1b to prevent protrusions when bent, and the packaging mount is made of a shrinkable film. It is possible to prevent the shrinkage film from being torn when it is coated with.

When the folded line 1a is used as the lead ruled line, the lower limit of the length of the ruled line 1b is preferably 10 mm, more preferably 15 mm. On the other hand, as the upper limit of the length of the ruled line 1b, 25 mm is preferable, and 20 mm is more preferable. If the length of the ruled line 1b is less than the above lower limit, the ruled line 1b may be broken. On the contrary, if the length of the ruled line 1b exceeds the above upper limit, the repulsive force when folded back becomes large, and there is a possibility that it becomes difficult to pack.

When the folded line 1a is used as the lead ruled line, the lower limit of the length of the perforation 1c is preferably 65 mm, more preferably 70 mm. On the other hand, the upper limit of the length of the perforation 1c is preferably 80 mm, more preferably 75 mm. If the length of the perforation 1c is less than the above lower limit, the ratio of the ruled line 1b becomes relatively large, so that the repulsive force when folded back becomes large, and packing may become difficult. On the contrary, if the length of the perforation 1c exceeds the above upper limit, the strength of the folding line 1a may be insufficient and the perforation line 1a may be easily broken.

One side edge 10a of the main body 10 that defines the boundary of the connecting flap 11 is composed of an easily bendable line. Examples of the easily bendable line include a ruled line, a perforation, a half-cut line, or a combination thereof. The easily bendable line may be a lead ruled line similar to the turnaround line 1a. Further, among the lead ruled lines, the length of the ruled line may be longer than the ruled line 1b of the folding line 1a, and the difference is preferably 3 cm or more and 8 cm or less. By increasing the length of the ruled line in this way, a difference in repulsive force is generated between the folded line 1a and the side edge 10a, and the folded line 1a is more easily bent. Due to this difference in easiness of bending, it is possible to easily assemble an article packaging body using the packaging mount.

The width of the connecting flap 11 (the length in the extending direction from the main body 10) is appropriately determined according to the thickness of the article to be packed, and can be, for example, 0.5 cm or more and 3 cm or less.

The end flap 12 is configured in the same shape as the connecting flap 11 on the side edge 10b facing one side edge 10a of the main body 10 except that the tip edges are not connected to each other.

As shown in FIG. 1, it is preferable that the other tongue pieces do not extend from both ends of the connecting flap 11 and the end flap 12. By not extending other tongue pieces from both ends of the connecting flap 11 and the end flap 12 in this way, when the article is packed using the shrinkable film, the tongue pieces interfere with each other and a gap is created at the corner. It can be prevented from occurring.

Further, as shown in FIG. 1, it is preferable that the side edges 11a and 12a of the connecting flap 11 and the end flap 12 are inclined inward toward the tip end side in the extending direction. By inclining the side edges 11a and 12a of the connecting flap 11 and the end flap 12 inward toward the tip end side in the extension direction in this way, the pair of side flaps 13 are bent and the tongue piece 14 described later Since the straight portion 14a comes into contact with the pair of side edges 11a and 12a, the pair of side flaps 13 are easily bent when the article is packed using the shrinkable film.

<Side flap>
The pair of side flaps 13 are square.

The other side edge 10c of the main body 10 that defines the boundary of the side flap 13 is composed of an easily bendable line. It is preferable that the easy-to-bend line forming the side edge 10c is of the same type as the easy-to-bend line forming the one side edge 10a of the main body 10 that defines the boundary of the connecting flap 11.

The width of the side flap 13 (the length in the extending direction from the main body 10) is the same as the width of the connecting flap 11.

<Tongue piece>
As shown in FIG. 2, the tongue piece 14 has a straight portion 14a extending from the base end side of the side flap 13 and an arc portion 14b connecting the tip of the straight portion 14a and the tip of the side flap 13. ..

The straight portion 14a is continuous with the side edge 10c of the main body 10 that defines the boundary of the side flap 13. Further, the straight portion 14a has a length equal to or slightly shorter than the width of the side flap 13.

As shown in FIG. 2, the arc portion 14b is preferably formed of 1/4 of a circle or an ellipse and has a squared tip. The arc portion 14b is not limited to a circle or an ellipse, and may be formed by a curve that bends in the same direction.

The proximal edge 14c that defines the boundary of the tongue piece 14 is composed of an easily bendable line. This easy-to-bend line can be formed of, for example, a ruled line formed by pressing a muscle, similarly to the above-mentioned bending guide line.

<Assembly method of article packaging>
Hereinafter, a method of assembling the article packaging body using the packaging mount will be described with reference to FIGS. 3 and 4.

First, as shown in FIG. 3, the article X is placed on one of the pedestal panels 1 of the packaging mount. When the other pedestal panel 1 is folded back, the article X is placed so as to be sandwiched between the pair of pedestal panels 1.

As the placement position of the article X, the center position in a plan view on the inner surface of the main body 10 of the pedestal panel 1 is preferable. Further, the article X may be arranged in a square formed in combination with any one of the first bending guide lines 15a constituting the bending guiding portion 15 or a part of the long side of the first bending guiding line 15a. More preferred.

Next, the other pedestal panel 1 is folded back along the folding line 1a, and the article X is sandwiched between the pair of pedestal panels 1 as shown in FIG.

At this time, the connecting flap 11, the end flap 12, the side flap 13, and the tongue piece 14 may be partially or completely bent along the easy-to-bend line, but not all of them may be bent. When it is bent, it is preferable that all of it is bent toward the inner surface side.

Subsequently, with the article X sandwiched between the pair of pedestal panels 1, the wrapping mount is passed through a shrink mounting machine (not shown) and the wrapping mount is covered with a shrinkable film. As a result, a packing body in which the article X is packed is formed.

When coated with the shrink film, the shrinking force causes the connecting flap 11, the end flap 12, the side flap 13 and the tongue piece 14 to be bent inward. FIG. 4 shows the state of the packaging mount after being covered with the shrink film. In FIG. 4, the shrink film is not shown.

Specifically, as shown in FIG. 4, the end flaps 12 and the side flaps 13 extending from the main body 10 of the respective pedestal panels 1 are in contact with the tips of the opposing flaps, and the article X It protrudes into a triangular columnar shape that is determined according to the thickness of the. The connection flap 11 in which the tip edges are connected to each other has the same shape.

As shown in FIG. 4, the tongue piece 14 is bent inward at the base end edge 14c that defines the boundary of the side flap 13, and the tongue pieces 14 and the arc portions 14b that face each other are abutted against each other. Further, the straight portion 14a of the tongue piece 14 and the side edge 12a of the end flap 12 are abutted against the end flaps 12 adjacent to each other at the corners of the package. With this configuration, the corners of the package are covered with the tongue piece 14.

As the article X becomes thicker, the angle formed by the opposing flaps becomes larger at the portion where the tips of the opposing end flaps 12 and the side flaps 13 abut each other. In this case, the tongue piece 14 is in a state of being rotated clockwise about the base end 14d of the straight line portion 14a shown in FIG. In this state, the straight portion 14a enters the inner surface side of the connecting flap 11 and the end flap 12, or overlaps along the outer surface. Further, since the arcuate portion 14b has an arcuate shape, the arcuate portions 14b facing each other maintain the abutted state. That is, even if the thickness of the article X changes, the state in which the corners of the package are covered with the tongue piece 14 is maintained. If the side edges 11a and 12a of the connecting flap 11 and the end flap 12 are inclined inward toward the tip side in the extension direction, the tongue piece 14 is unlikely to interfere with the connecting flap 11 and the end flap 12. , Can rotate smoothly.

<Advantage>
In the packaging mount, when the article X is packed using the shrinkable film, the pair of side flaps 13 have their tips bent and abutted against each other, so that the gap between the pair of pedestal panels 1 can be covered. .. At that time, the pair of tongue pieces 14 extending from both ends of the pair of side flaps 13 are further bent. At this time, the straight portion 14a of the tongue piece 14 closes the gap between the connecting flap 11 and the side edge of the end flap 12, and the arc portions 14b of the facing tongue pieces 14 are bent so as to be abutted against each other. It is possible to cover the gap generated at the corner between the pedestal panels 1. Further, since the pair of tongue pieces 14 can cover the gaps generated at the corners regardless of the bending angle of the side flaps 13 by the arc portion 14b of the tongue pieces 14, the packaging mount is the thickness of the article X to be packed. Regardless, when packing the article X using the shrinkable film, gaps are unlikely to occur at the corners.
