Description

The present invention relates to a packaging tool for packaging an object to be packaged and a packaging box for storing the packaging tool.

With the spread of mail-order sales such as online shopping, the transportation of products using courier services is widely used. In the transportation of these products, there is a demand for packaging tools capable of stably transporting various packaging objects having different shapes and sizes.

As a packaging tool of this type, conventionally, one having a plate-shaped member and a tubular stretchable flexible film member in which the plate-shaped member is housed is known (see Patent Document 1).

In this packaging tool, the plate-shaped member has a mounting portion on which the object to be packaged is placed and standing portions arranged on both sides of the mounting portion, and the boundary between the mounting portion and the standing portion. A first folding curve that allows the upright portion to be valley-folded above the mounting portion is provided, and a second folding portion that is orthogonal to the first folding curve and that allows the mounting portion and the folded portion to be valley-folded. It has a fold curve.

When the packaging object is packaged with such a packaging tool, the plate-shaped member is valley-folded at the second folding curve to create a gap between the plate-shaped member and the flexible film member, and the packaging object is inserted. To do. Then, when each upright portion is bent upward from the first folding curve, the second folding curve that was previously bent is restored to the original unfolded state, whereby the flexible film member is tensioned. To do.

As a result, the object to be packaged is supported by being crimped to the mounting portion by the flexible film member. This packaging tool is housed in an outer box such as corrugated cardboard in a state of wrapping the object to be packaged and transported as a packaging box.

Special Table No. 9-501128

However, in this type of packaging tool, it is necessary to increase the crimping force of the flexible film member in order to prevent the object to be packaged from moving from the mounting portion when the outer box is impacted. is there. In order to increase the crimping force, for example, it is conceivable to design the tubular flexible film member to have a small circumferential dimension. However, if the size is reduced, there is a disadvantage that it becomes difficult to insert the object to be packaged between the mounting portion and the flexible film member.

In view of the above points, it is an object of the present invention to provide a packaging tool and a packaging box which can be easily packaged and can improve the bearing capacity to the object to be packaged.

In order to achieve such an object, the packaging tool of the present invention is formed of corrugated cardboard, and is connected to a mounting portion on which the object to be packaged is placed and on both sides of the mounting portion, respectively, via bending lines. A plate-shaped member having a pair of upright portions and a flexible thin film member which is tubular and into which the plate-shaped member is inserted so as to cover at least the above-mentioned mounting portion, and the plate-shaped member is flat. In a packaging tool that can be deformed from an unfolded state to an upright state in which the upright portion is bent upward, the above-mentioned resting portion has the edge from the length of both edges along the end edge of the plate-shaped member in the unfolded state. It is characterized in that the length of the central portion parallel to the portion is formed to be large, and the central portion is bent so as to be upward from both edge portions in the upright state.

Since the packaging tool of the present invention is inserted into the tubular thin film member so as to cover the mounting portion of the plate-shaped member, the packaging tool is packaged in the gap between the mounting portion of the plate-shaped member and the thin film member. The object to be packaged can be placed on the mounting portion of the plate-shaped member by inserting the object.

Further, since standing portions are continuously provided on both sides of the mounting portion via a folding line, the standing portion is bent upward from the bending line so that the standing portion is on the upper side with respect to the mounting portion. Stand up in.

Here, in the above-described mounting portion, the length of the central portion parallel to the edge portion is formed to be larger than the length of both edge portions along the edge of the plate-shaped member in the deployed state. The upright portion adjacent to the portion has a recessed lower end such that the central portion is located upward with respect to both ends including both edge portions when the upright portion is erected.

Therefore, when the erecting portion is erected, the previously described resting portion formed of corrugated cardboard is bent so as to follow the recessed shape, and the central portion is above the both edge portions. As a result, the packaging object on the mounting portion is pushed upward, so that the thin film member is pulled upward through the packaging object and becomes tense.

Therefore, in the packaging tool of the present invention, the bearing capacity to the object to be packaged can be improved, and the circumferential dimension of the thin film member is designed to be a certain size larger than the circumference of the plate-shaped member to form a mounting portion. It is possible to facilitate the packing work of inserting the packaging object into the gap between the thin film member and the thin film member.

Further, in the present invention, it is preferable that the boundary between the above-mentioned placing portion and the standing portion on both sides is arcuate.

According to this, since the base end of the standing portion has an arc shape, the mounting portion in the standing state can be easily bent so that the central portion is above the both edge portions.

Further, in the present invention, it is preferable that the plate-shaped member has a second bending line capable of crossing the mounting portion and both standing portions and valley-folding the mounting portion and both standing portions.

According to this, when the object to be packaged is inserted into the gap between the plate-shaped member and the thin film member, the gap is created by valley-folding the mounting portion and both standing portions by the second bending line. Since it becomes large, it is possible to easily insert the object to be packaged.

Therefore, even if the circumferential dimension of the tubular thin film member is designed to be small, the packaging work of inserting the packaging object into the gap between the mounting portion and the thin film member is facilitated, and the crimping force of the thin film member is increased for packaging. It is possible to improve the bearing capacity for the object.

Further, the wrapping box of the present invention is a wrapping box including a wrapping tool and an outer box for storing the wrapping tool, and the wrapping tool is formed of a cardboard paperboard and is loaded with an object to be packaged. A plate-shaped member having a pair of standing portions connected to each side of the mounting portion and the mounting portion via bending lines, and the plate-shaped member having a tubular shape and covering at least the above-described resting portion. The plate-shaped member is provided with a flexible thin film member to be inserted, and the plate-shaped member can be deformed from a flat unfolded state to an upright state in which the upright portion is bent upward. In the above, the length of the central portion parallel to the edge portion is formed larger than the length of both edge portions along the edge of the plate-shaped member, and in the upright state, the central portion is formed from the both edge portions. It is bent so as to be upward, and the facing inner side surfaces of the outer box are in contact with the outer surfaces of both standing portions housed in an upright state.

According to this, since the outer surface of the upright portion of the stored packaging tool comes into contact with the inner side surface of the outer box, the packaging tool is supported by the outer box, so that the supporting force to the packaging object is improved. Can be made to.

The development view of the plate-shaped member which concerns on the modification of this invention.

An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the packaging tool 1 for transporting goods (hereinafter referred to as packaging tool 1) of the present embodiment has a plate-shaped member 2 and a flexible film (thin film member) 3. The packaging tool 1 holds the packaging object A between the plate-shaped member 2 and the flexible film 3, and accommodates the packaging object A in the outer box 4. The outer box 4 may be used as a packaging box as it is, or may accommodate two or more boxes in a larger packaging box.

As shown in FIG. 2, the plate-shaped member 2 is a substantially square plate divided into a mounting portion 21 and standing portions 22, 22 arranged on both sides of the mounting portion 21. The plate-shaped member 2 is made of, for example, thick paper or corrugated cardboard.

The mounting portion 21 is a portion on which the packaged article secured in the central region of the plate-shaped member 2 is placed, and the central portion 21t is longer than the vertical edge portion 21s along the edge of the plate-shaped member 2. It has a shape that bulges to the left and right. The upright portion 22 is a portion that is continuously provided on the left and right edge edges of the mounting portion 21 via a crease line (folding line) a and is folded upward.

The crease line a is an arcuate curve formed in a convex shape in the left-right direction from both sides of the mounting portion 21. The fold lines a and a are formed symmetrically in the vertical direction, and the pair of fold lines a are formed symmetrically in the horizontal direction.

As a result, the upright portion 22 can be bent to a position substantially vertically upward with respect to the mounting portion 21, and is prevented from being excessively bent toward the upper surface side of the mounting portion 21 beyond this position.

The plate-shaped member 2 is formed with a fold line b that passes through the mounting portion 21 and the standing portions 22 and 22 and intersects the fold lines a and a. The fold line b is a fold line that can be folded in a valley parallel to the upper and lower end edges of the plate-shaped member 2. The fold line b corresponds to the second fold line of the present invention.

The flexible film 3 is formed of, for example, a flexible film made of a synthetic resin film such as polyethylene terephthalate, polyethylene, polypropylene, polycarbonate, and polyvinyl chloride. Further, the flexible film 3 has a tubular shape, and the plate-shaped member 2 is inserted from one of the openings in the direction along the crease line b.

The flexible film 3 needs to be formed so as to cover at least the packaging object A in the axial direction, and is formed so as to cover the mounting portion 21 in the present embodiment.

The length of the flexible film 3 in the circumferential direction is designed to be about the same as or slightly larger than the outer circumference of the plate-shaped member 2 in the lateral direction so that the plate-shaped member 2 can be accommodated. Since the flexible film 3 is flexible and stretchable, and the plate-shaped member 2 can be bent at the crease line b, it is more flexible than the outer circumference of the plate-shaped member 2 in the lateral direction. The film 3 can also be designed to be slightly smaller. That is, the length of the flexible film 3 in the circumferential direction can be appropriately selected depending on the size of the packaging object A to be stored.

In the present embodiment, the plate-shaped member 2 is only inserted into the flexible film 3 and is not fixed, but the present invention is not limited to this, and the packaging object A is not inserted. The plate-shaped member 2 and the flexible film 3 on the side can also be fixed by adhesive / heat welding.

Next, a procedure for packaging the object to be packaged A using the packaging tool 1 will be described with reference to FIGS. 3 to 5.

First, as shown in FIG. 3, the plate-shaped member 2 is folded into a valley fold along the crease line b. Next, the object to be packaged A is inserted between the mounting portion 21 of the plate-shaped member 2 and the flexible film 3. At this time, as described above, by bending the plate-shaped member 2 in advance, the flexible film 3 is loosened, so that the packaging object A can be easily inserted.

Next, as shown in FIG. 4, the plate-shaped member 2 bent along the crease line b is restored to a flat plate shape against the tension of the flexible film 3. As a result, the flexible film 3 is pulled and tense toward both end edges of the mounting portion 21, and presses the packaging object A against the mounting portion 21. As a result, the packaging object A is fixed in a predetermined position.

Further, as shown in FIG. 4, the standing portions 22, 22 are bent toward the surface side of the mounting portion 21 along the crease lines a and a (in the direction of the arrow in FIG. 4). As a result, as shown in FIG. 5, the packaging of the packaging object A using the packaging tool 1 is completed.

FIG. 6 is a sectional view taken along line VI-VI of the packaged tool 1 shown in FIG.

As shown in FIG. 6, the base ends (lower edges in FIG. 6) of the bent upright portions 22 and 22 have an arc shape in which the central portion is arranged above the left and right ends along the crease line a. To form.

At this time, since the mounting portion 21 is formed of corrugated cardboard, it is deformed by the proximal ends of the standing portions 22 and 22 so as to follow the arc shape of the proximal ends. As a result, as shown in FIG. 6, the mounting portion 21 is curved in an arch shape so that the central portion 21t is above the both edge portions 21s. As a result, the mounting portion 21 is curved upward, so that the packaging object A mounted on the mounting portion 21 is also moved upward.

At this time, as shown in FIG. 6, since the flexible film 3 is hooked on the lower side by the edge along the longitudinal direction of the plate-shaped member 2, it is to be wrapped with respect to the upper inner peripheral surface. The object A is moved upward and strongly pressed.

As a result, according to the packaging tool 1 in the present embodiment, the mounting portion 21 is deformed upward in a convex shape, so that the bearing capacity for the packaging object A can be further improved.

Finally, as shown in FIG. 1, the packaging tool 1 is stored in the outer box 4.

The internal space of the outer box 4 is designed to be slightly larger than the upright packaging tool 1 so that the packaging tool 1 can be stored.

Therefore, when the upright packaging tool 1 is stored in the outer box, both outer surfaces of the upright standing portions 22, 22 come into contact with the inner side surfaces of the outer box, respectively. In particular, since the upright portion 22 is deformed into the upright state by forcibly bending the corrugated cardboard, the outer surface is pressed against the inner side surface of the outer box because it tries to return to the unfolded state.

As a result, the packaging tool 1 is supported inside the outer box 4, so that the packaging object A can be supported.

In the above description, in FIG. 4, after returning the plate-shaped member bent along the crease line b to the original state in which it is not bent, the standing portions 22 and 22 are placed on the fold lines a and a. It was explained that it was bent toward the surface side of. However, since the fold line b and the fold line a intersect, both fold lines cannot be bent at the same time. Therefore, when the fold line a is forcibly bent, the fold line b that has been bent earlier becomes , It is automatically restored to its original unfolded state.

That is, as shown in FIG. 3, in a state where the packaging object A is inserted between the mounting portion 21 of the plate-shaped member 2 and the flexible film 3, the standing portions 22 and 22 are placed on the mounting portion 21. By bending it toward the surface side, the state shown in FIG. 4 can be omitted and the packaging shown in FIG. 5 can be completed.

In the present embodiment, the arcuate crease line a has been described as the crease line of the plate-shaped member, but the present invention is not limited to this, and the modifications 1 to 2 as shown in FIGS. 7A to 7C are not limited thereto. It may be 3.

As shown in FIG. 7A, the crease line a2 according to the modified example 1 is a mountain-shaped straight line formed convexly in the left-right direction from both sides of the mounting portion 21, with respect to either the up-down direction or the left-right direction. Is also formed line-symmetrically. At this time, the mounting portion 21 can be further easily deformed by providing an auxiliary fold line connecting the mountain-shaped vertices (bending points) of each fold line a1. The auxiliary crease line may be provided in the following modifications 2 and 3.

As shown in FIG. 7B, the crease line a3 according to the modified example 2 includes a first straight line portion extending in the vertical direction parallel to the left and right edge edges of the plate-shaped member 2, and the end portion and the plate-shaped member of the first straight line portion. It is formed from an inclined portion that is connected to two adjacent upper and lower end edges and is inclined in a direction away from the adjacent left and right end edges. As a result, the central portion of the mounting portion 21 on which the packaging object A is actually mounted can be flattened, so that the packaging object A can be reliably moved upward to further improve the bearing capacity. Can be done.

As shown in FIG. 7C, the crease line a4 according to the modified example 3 is parallel to the first straight line portion extending in the vertical direction parallel to the left and right edge edges of the plate-shaped member 2 and the extension line of the first straight line portion. An inclined portion that connects the second straight portion extending in the linear direction inside the first straight portion above or below the first straight portion and the end of the second straight portion adjacent to the end of the first straight portion. It is formed from and. As a result, the central portion of the mounting portion 21 on which the packaging object A is actually mounted can be flattened, so that the packaging object A can be reliably moved upward to further improve the bearing capacity. Can be done. Further, since the lower side of the packaging tool 1 and the inner floor surface of the outer box 4 can be brought into surface contact with each other, the packaging tool 1 can be stably placed.

In the present embodiment and the above-described modification, a curved line and a straight line having a bending point have been described as the fold line a, but the present invention is not limited to this, and one fold line a is not limited to this. However, it may have a straight line region and a curved region.

In the present embodiment and the above-described modification, the case where the central portion 21t of the mounting portion 21 is arranged in the center in the vertical direction has been described as an example, but the present invention is not limited to this. That is, the longest portion of the mounting portion 21 in the left-right direction may be upward or downward from the center instead of the center in the vertical direction.
