Description

[Technical field]

[0001] The present invention relates to a fixing sheet that can restrict the movement of items stored inside a packaging box and fix them in place. [Background technology]

[0002] Conventionally, in order to prevent items in a box from shifting and being damaged during transportation, cushioning materials have been used to fill gaps between the items, and sheet materials have been used to hold down the items from above. For example, the movement restricting member (corrugated cardboard) in Patent Document 1 below includes a first sheet portion having first fold lines formed in the center of both end edges parallel to the end edges, and a pair of second sheet portions.

[0003] When arranging the movement restricting member inside a box, the first fold line of the movement restricting member is folded in a mountain fold and the second fold line is folded in a valley fold into a substantial W shape, and the movement restricting member is placed over the stored items inside the box. As a result, the movement restricting member spreads due to the restoring forces of the first fold line and the second fold line, and each side edge of the second sheet portion is engaged with the inner side wall of the storage box, thereby fixing the movement of the stored items inside the box and restricting the movement of the stored items (Patent Document 1 / paragraphs 0024, 0026, 0039, Figure 1-2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility model registration No. 3168700 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the movement restricting member in Patent Document 1 is made of cardboard and can only be folded along the first and second fold lines, which causes a problem that the movement restricting member cannot fix stored items unless the stored items have a specific shape and number.

[0006] Furthermore, the movement restricting member of Patent Document 1 has a problem in that the fixing force is weak because each side edge of the second sheet portion is engaged with the inner wall of the packaging box.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide a fixing sheet that can securely fix items inside a packaging box regardless of the shape of the items. [Means for solving the problem]

[0008] The present invention is a fixing sheet made of a single rectangular piece of cardboard that holds down and fixes items stored inside a packaging box from above, and is characterized by having a holding portion whose length in one direction is less than or equal to the inner dimension of the bottom of the packaging box in one direction and whose length in the other direction is longer than the inner dimension of the bottom of the packaging box in the other direction, and locking pieces that are connected to both end edges of the holding portion in one direction and both end edges in the other direction via fold lines and are engaged with the inner wall of the packaging box.

[0009] The fixing sheet of the present invention is made of cardboard, and the length of the holding part in the other direction is longer than the inner dimension of the bottom of the packaging box in the other direction, so that the fixing sheet can be deformed according to the shape of the stored items and hold the stored items from above.

[0010] In addition, the fixing sheet of the present invention has locking pieces formed on both ends of the pressing part in one direction and both ends of the pressing part in the other direction, so that the periphery of the pressing part is locked to the inner wall of the packaging box by the locking pieces. Therefore, the fixing sheet can reliably fix the stored items in the packaging box.

[0011] In the fixing sheet of the present invention, it is preferable that the locking pieces provided on both end edges in the one direction are adjacent to each other in the other direction with gaps therebetween, forming a plurality of flaps that can be independently folded.

[0012] With this configuration, when the other direction of the retaining portion is deformed to match the shape of the stored item, the multiple flaps can be folded independently, so the valley-folded locking piece does not bulge and impede this deformation. Therefore, the fixing sheet with this configuration can deform the retaining portion to match the shape of the stored item, and can reliably fix the stored item with the multiple flaps.

[0013] Furthermore, in a fixing sheet having the above-mentioned configuration, it is preferable to have an imaginary line drawn parallel to the one direction from the gap formed at one side edge in the one direction toward the gap formed at the other side edge in the one direction.

[0014] According to this configuration, the retaining portion can be easily deformed along the imaginary line, so that the stored item can be securely fixed in place by the retaining portion in accordance with the shape, etc., of the stored item.

[0015] In addition, in the fixing sheet of the present invention, it is preferable that the length of the holding portion in one direction coincides with the inner dimension in one direction of the bottom of the packaging box.

[0016] A fixing sheet having this configuration can be engaged with the inner wall of a packaging box by the entire back surface of the engaging pieces formed on both end edges in one direction, thereby enabling stored items to be securely fixed. [Brief description of the drawings]

[0017] [Figure 1] FIG. 2 is a plan view of the fixed sheet according to the embodiment of the present invention. [Diagram 2] FIG. [Diagram 3] 3 is a cross-sectional view of the packaging box taken along line III-III in FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The fixing sheet according to the embodiment of the present invention will be described in detail below with reference to the drawings. Fig. 1 is a plan view of the fixing sheet 1 of the present embodiment as seen from above. Fig. 2 is an overall perspective view of a packaging box 10 including the fixing sheet 1 of the present embodiment.

[0019] The fixing sheet 1 shown in FIG. 1 is made of cardboard, and has a rectangular holding portion 2 that holds down the stored object from above, and a fold line L on the periphery of the holding portion 2. A ~L D The locking pieces 3 to 6 are connected to each other via locking pieces 3 to 6. The locking pieces 3 to 6 are members that are locked to the inner side walls of the packaging box 10 (see FIG. 2) and fix the position.

[0020] The pressing portion 2 of this embodiment has a length (width S) of 242 mm in the short direction, which is the "one direction" of the present invention, and a length (width T) of 342 mm in the long direction, which is the "other direction" of the present invention.

[0021] As shown in the figure, the retaining portion 2 has locking pieces 3 to 6 each having a height (width U) of 10 mm formed on both ends in the short direction and both ends in the long direction. A ~L D 2 in a direction rising from the plane of the pressing portion 2. This allows the periphery of the pressing portion 2 to be locked to the inner side wall of the packaging box 10 by the locking pieces 3 to 6, so that the fixing sheet 1 can reliably fix the contents inside the packaging box. The sizes of the pressing portion 2 and the locking pieces 3 to 6 can be changed as appropriate according to the size of the packaging box 10.

[0022] In addition, since the locking piece 3 has four gaps 7, the locking piece 3 is composed of five flaps 3a to 3e. The flaps 3a to 3e formed adjacent to each other are aligned along the fold line L. A It can be bent independently of the other.

[0023] Similarly, the locking piece 4 is composed of five flaps 4a to 4e (the fold lines are L B ), and the locking piece 5 is composed of five flaps 5a to 5e (the fold lines are LC ), the locking piece 6 is composed of five flaps 6a to 6e (the fold lines are L D In this embodiment, each of the locking pieces 3 to 6 has five flaps, but the number of flaps can be changed as appropriate.

[0024] When the longitudinal direction of the pressing portion 2 is deformed to match the shape of the stored item, the flaps 3a-3e, 5a-5e can be folded independently. Therefore, the valley-folded locking pieces 3, 5 are not stretched and hinder this deformation. Therefore, the fixing sheet 1 can deform the locking pieces 3, 5 to match the shape of the stored item, and can reliably fix the stored item with the multiple flaps.

[0025] In addition, the flaps provided on one side of the fixing sheet 1 may be provided with a large gap therebetween. For example, the locking pieces 3 may be provided with flaps on every other side (constituted by flaps 3a, 3c, and 3e in FIG. 1).

[0026] As shown in the figure, the gap 7 is provided at the same position on opposing sides (for example, the locking pieces 3 and 5) of the fixing sheet 1. That is, an imaginary line M (dashed line) parallel to the short side direction can be drawn from the gap 7 formed on one side edge (the side on which the locking piece 3 is formed) of the sides extending in the longitudinal direction of the fixing sheet 1 to the gap 7 formed on the other side edge (the side on which the locking piece 5 is formed).

[0027] Therefore, the imaginary line M connecting the gaps 7 tends to be a bending point when the holding portion 2 is deformed, making it easier to deform. As long as the imaginary line M can be drawn, the number and spacing of the flaps on the opposing sides of the fixing sheet 1 can be arbitrary. Since the holding portion 2 is more easily deformed along the imaginary line M, the stored item can be reliably fixed by the holding portion 2 in accordance with the shape, etc., of the stored item.

[0028] The length (242 mm) of the pressing portion 2 in the short side direction is equal to or smaller than the inner dimension (width s in FIG. 2) of the short side direction of the bottom of the packaging box 10, but at least the distance from the tip of the locking piece 3 to the tip of the locking piece 5 exceeds the inner dimension (width s in FIG. 2) of the short side direction of the bottom of the packaging box 10. Therefore, the tips of the locking pieces 3 and 5 are locked to the inner side walls of the packaging box 10 in the short side direction.

[0029] It is desirable that the length of the pressing portion 2 in the short side direction coincides with the inner dimension in the short side direction of the bottom of the packaging box 10. In this way, the locking pieces 3, 5 formed on both ends of the pressing portion 2 in the short side direction are raised, and the entire back surfaces of the locking pieces 3, 5 are locked to the inner side wall of the packaging box 10. Therefore, the fixing sheet 1 can reliably fix the contents in the packaging box 10.

[0030] The length (342 mm) of the pressing portion 2 in the longitudinal direction is longer than the inner longitudinal dimension (width t in FIG. 2) of the bottom of the packaging box 10. The longitudinal direction of the pressing portion 2 is limited to the length when it is bent in the longitudinal direction to the height of the top plate of the packaging box 10, together with the bottom end surface of the packaging box 10, to draw an arch.

[0031] Furthermore, since the fixing sheet 1 has the locking pieces 4 and 6, when the fixing sheet 1 is placed in the packaging box 10, it can be fixed. The fixing sheet 1 is deformed according to the height and unevenness of the stored items, and the locking pieces 4, 6 are securely locked to the inner side walls of the packaging box 10 in the longitudinal direction.

[0032] In this way, one side of the pressing portion 2 is long enough not to exceed the above-mentioned upper limit in the corresponding direction of the bottom of the packaging box 10 so that the fixing sheet 1 can deform according to the shape of the stored item. For example, it is more preferable that the length of the side of the pressing portion 2 is 1.2 times or more the inner dimension of the corresponding direction of the bottom of the packaging box 10. This allows the locking pieces 4, 6 of the fixing sheet 1 to contact the inner wall of the packaging box 10 at a relatively deep position at both end edges in that direction. Therefore, the stored item can be reliably fixed by the fixing sheet 1.

[0033] In addition, holes 8a and 8b (diameter 20 mm) are provided on a straight line (center line) extending in the longitudinal direction of the retaining portion 2 of the fixing sheet 1. The holes 8a and 8b make it easy for an operator to curve the fixing sheet 1 with his / her fingers to match the shape of the stored object when placing the fixing sheet 1 in the packaging box 10. The holes 8a and 8b are also useful for checking the type of the stored object without removing the fixing sheet 1.

[0034] In addition, an operator can easily remove the fixing sheet 1 by inserting his / her fingers into the holes 8a and 8b. The holes are not limited to being circular, and may be polygonal, for example. The number of holes is not limited to two, and the diameter of the holes can be changed according to the purpose.

[0035] 2 is made of, for example, cardboard, and is a rectangular box having a short side direction and a long side direction corresponding to the shape of the fixing sheet 1. The packaging box 10 may be a cube, and may be made of a material other than cardboard, such as paper or acrylic.

[0036] After storing the items P1 to P3 inside the packaging box 10, the worker presses the fixing sheet 1 from above to fix the position. As described above, the longitudinal direction of the fixing sheet 1 (retaining portion 2) is made longer than the longitudinal inner dimension (width t) of the bottom of the packaging box 10, so that the fixing sheet 1 can be freely deformed according to the height and unevenness of the stored items.

[0037] After the items P1 to P3 are stored inside the packaging box 10, the fixing sheet 1 may be placed on the upper surfaces of the items P1 to P3 and pressed and fixed by a pressing device (not shown) until a preset pressure is reached.

[0038] In this case, it is preferable that the pressing device has a function of moving the pressing part to a target position, or that a conveyor device is used to move and press the packaging box 10. In this way, by using the fixing sheet 1, the movement of the stored items P1 to P3 inside the packaging box 10 can be restricted, and the stored items P1 to P3 can be fixed securely.

[0039] FIG. 3 shows a cross-sectional view of the packaging box 10 of FIG. 2 taken along line III-III (longitudinal direction).

[0040] Items P1 to P3 of different heights are stored inside the packaging box 10. As shown in the figure, the fixing sheet 1 deforms to match the heights and irregularities of the items P1 to P3, and holds down and fixes the items P1 to P3 from above.

[0041] The top surfaces of the stored items P1 to P3 are covered by the retaining portion 2 of the fixing sheet 1, and both ends in the longitudinal direction of the packaging box 10 are locked by the locking pieces 4 and 6. In addition, the short side (rear side) of the packaging box 10 is locked by the locking piece 3, so that the stored items P1 to P3 can be securely fixed.

[0042] As the storage item, a cylindrical container such as a can or a plastic bottle is placed in the center of the packaging box 10. In this case, both longitudinal ends of the pressing portion 2 are aligned with the bottom end surface of the packaging box 10 to form the fixing sheet 1 in an arch shape. This allows the cylindrical container to be fixed in place by pressing it from above in the center of the packaging box 10.

[0043] Furthermore, when two cylindrical containers are laid down on the longitudinal ends of the packaging box 10, both longitudinal ends of the pressing part 2 are locked to the inner wall of the packaging box 10 (above the cylindrical containers) by the locking pieces 4, 6. At this time, the longitudinal center of the pressing part 2 is partially in contact with the bottom plate of the packaging box 10, so that the two cylindrical containers can be pressed down from above and fixed in place.
