Description

  The present invention relates to a piece of paper for forming a cushioning material, and more particularly to a cushioning piece of paper that can form a three-dimensional shaped cushioning material by bending.

  A cushioning material is used to fill a gap in the cardboard case that is generated when goods or the like are stored in the cardboard case for packing. Even if some vibration occurs when the cardboard case containing the product is transported, the cushioning material protects the product.

  As this cushioning material, a polyethylene air cap or the like has been used in the past, but recently, from the standpoint of environmental protection, a cushioning material formed three-dimensionally by folding a piece of paper such as cardboard is used. There are many cases.

There are various shapes of paper pieces assembled as such cushioning materials, that is, cushioning material paper pieces. For example, there is a cushioning paper piece to be assembled as a substantially triangular prism-shaped cushioning material (see, for example, Patent Document 1).

  However, the conventional cushion material sheet has many protrusions and notches. For this reason, in the process of manufacturing the cushioning paper sheet while cutting the cardboard base paper, a large number of missing parts are generated. In other words, the base paper cannot be used effectively without waste.

  Moreover, the conventional cushioning material paper piece is formed so that it can be assembled only in one specific shape. Therefore, it is necessary to prepare a buffer material sheet piece having a different configuration for each product to which the buffer material is applied and depending on the position where the buffer material is to be disposed.

  It is an object of the present invention to provide a shock-absorbing paper piece that has few missing parts in the process of manufacturing from base paper and can be assembled into various shapes.

  In order to solve the above problems, the cushioning paper piece according to the present invention is a substantially rectangular cushioning paper piece whose peripheral edge is composed of a left side, a right side, an upper side, and a lower side, and is substantially parallel to the left side. A plurality of substantially straight crease lines are formed and divided into a plurality of regions by the crease lines, and a locking tongue piece is formed between them by two cuts from the upper side in each region, and / or A locking tongue piece is formed between the two cuts from the lower side in the region, and each locking tongue piece is formed at a substantially central portion in the lateral width direction of each region, and is constituted by cardboard or paperboard. That is, a locking tongue piece may be formed between the two cuts from the upper side in each region, or a locking tongue piece may be formed between the two cuts from the lower side in each region. Good. Furthermore, the locking tongue piece may be formed between the two cuts from the upper side in each region, and the locking tongue piece may be formed between the two cuts from the lower side.

  In the buffer material sheet piece, one or more substantially perforated lines that are substantially parallel to the upper side may be formed.

  Moreover, in the cushioning material sheet piece, a locking tongue piece is formed between the two perforations in the upward direction from the perforation line in each region, or / and the downward direction from the perforation line in each region. A locking tongue piece may be formed between the two cuts, and each locking tongue piece formed by the cut from the perforation line may be formed at a substantially central portion in the lateral width direction of each region. That is, a locking tongue piece may be formed between the two perforations in the upward direction from the perforation line in each region, and between the two perforations in the downward direction from the perforation line in each region. A locking tongue piece may be formed. Further, in each region, a locking tongue piece is formed between the two notches extending upward from the perforation line, and is locked therebetween by two notches extending downward from the perforation line. A tongue piece may be formed.

  Further, in the cushion material sheet piece, five crease lines are formed, so that it is divided into six regions, and the third fold line from the left of the five crease lines is the cushion material sheet. It is arranged at a substantially central portion in the lateral width direction of the piece, and is arranged so that the five crease lines are left-right symmetric, and the locking tongue piece in the leftmost region and the locking tongue in the second region from the left The distance from the piece and the distance between the locking tongue piece in the rightmost region and the locking tongue piece in the second region from the right may be substantially equal.

It may be.

  According to the present invention, there are fewer missing parts in the process of manufacturing the buffer material sheet piece from the base paper, and one buffer material sheet piece can be assembled into various shapes.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  First, referring to FIG. 1, a schematic configuration of a cushioning paper piece 10 according to an embodiment of the present invention will be described.

  FIG. 1 is a plan view of a cushioning paper sheet 10 according to an embodiment of the present invention. The shape of the cushioning paper piece 10 is substantially rectangular. Its short side length (S0) is about 350 mm, and its long side length (W0) is about 450 mm. Further, the cushioning paper piece 10 is made of corrugated cardboard, and its thickness (t) is about 3 mm.

  As described above, the shape of the cushioning material sheet 10 is a rectangular shape having four sides. That is, the peripheral edge of the cushioning paper piece 10 is composed of the left side 21, the right side 22, the upper side 31, and the lower side 32. The left side 21 and the right side 22 are parallel, and the upper side 31 and the lower side 32 are parallel. The left side 21 is perpendicular to the upper side 31 and the lower side 32, and the right side 22 is also perpendicular to the upper side 31 and the lower side 32.

  As can be understood from the figure, the buffer sheet piece 10 is formed with five substantially straight crease lines B1, B2, B3, B4, and B5 substantially parallel to the left side 21. The crease lines B1, B2, B3, B4, and B5 vertically cut the cushioning material sheet piece 10 from the upper side 31 to the lower side 32. The cushioning paper piece 10 is divided into six regions from the first region R1 to the sixth region R6 by the crease lines B1, B2, B3, B4, and B5. These six regions R1, R2, R3, R4, R5, and R6 are all rectangular in shape.

  The five crease lines B1, B2, B3, B4, and B5 are arranged symmetrically in the cushioning paper piece 10. In other words, the crease line B3 is arranged at a substantially central portion in the width direction of the cushioning paper piece 10, and the crease line B1 and the crease line B5 are arranged symmetrically about the crease line B3, and the crease line B2 And the crease line B4 are arranged symmetrically about the crease line B3. Accordingly, the lateral width W1 of the first region R1 and the lateral width W6 of the sixth region R6 are the same, the lateral width W2 of the second region R2 and the lateral width W5 of the fifth region R5 are the same, and the third The lateral width W3 of the region R3 and the lateral width W4 of the fourth region R4 are the same.

  Further, the square value of the lateral width dimension W3 of the third region R3 is substantially equal to the sum of the square value of the lateral width dimension W1 of the first region R1 and the square value of the lateral width dimension W2 of the second region R2. Further, the square value of the lateral width dimension W4 of the fourth region R4 is substantially equal to the sum of the square value of the lateral width dimension W6 of the sixth region R6 and the square value of the lateral width dimension W5 of the fifth region R5.

  Further, the buffer sheet 10 is provided with a single substantially perforated line 41 substantially parallel to the upper side 31. The perforation line 41 crosses the cushioning material sheet piece 10 from the left side 21 to the right side 22. The distance S1 from the upper side 31 to the perforation line 41 is shorter than the distance S2 from the lower side 32 to the perforation line 41. The distance S1 is about 110 mm and the distance S2 is about 240 mm.

  The buffer paper sheet 10 has four locking tongue pieces G for each region. Therefore, 24 locking tongue pieces G are formed in the entire cushioning material paper piece 10.

  More specifically, first, in each region R1, R2, R3, R4, R5, R6, two cuts C from the upper side 31 are formed, and the locking tongue is provided between the two cuts C. A piece G is formed. In each region, two cuts C from the lower side 32 are formed, and a locking tongue piece G is formed between the two cuts C.

  Further, in each region, two incisions C directed upward from the perforation line 41 are formed, and a locking tongue piece G is formed between the two incisions C. Further, in each region, two cuts C are formed downward from the perforation line 41, and a locking tongue piece G is formed between the two cuts C.

  These locking tongue pieces G are formed in each region at a substantially central portion in the lateral width direction (of each region).

  As described above, since the five crease lines B1, B2, B3, B4, and B5 are arranged symmetrically in the cushioning paper piece 10, the locking tongue piece G and the second region in the first region R1 The distance La between the locking tongue piece G of R2 and the distance Lb between the locking tongue piece G of the sixth region R6 and the locking tongue piece G of the fifth region R5 are substantially equal.

  The cushioning paper piece 10 can be used without being cut at the perforation line 41, or can be used by being cut at the perforation line 41 and divided into two paper pieces.

  FIG. 2 shows a state in which the cushioning paper sheet 10 is cut at the perforation line 41 and divided into two paper sheets 11 and 12.

  FIG. 3 is a perspective view of the cushioning material 51 formed by bending the paper piece 11 obtained by cutting the cushioning material paper piece 10 along the perforation line 41. The buffer material 51 is formed as follows. That is, first, the paper piece 11 is bent at all five crease lines B1, B2, B3, B4, and B5, and the first region R1 and the sixth region R6 are overlapped. Then, a pentagonal cylinder is formed. Further, the latching tongue piece G in the first region R1 and the latching tongue piece G in the sixth region R6 are folded inward (inward of the cylinder) while being overlapped. Then, the first region R1 and the sixth region R6 are maintained in a state where they are overlapped. In this manner, the pentagonal columnar cushioning material 51 is completed.

  4 is a longitudinal sectional view of the cushioning material 51 shown in FIG. As shown in this cross-sectional view, the locking tongue G of the first region R1 and the locking tongue G of the sixth region R6 are folded inward while being overlapped. Such a coupling mechanism by the locking tongue piece G is formed in two places at the top and bottom.

  3 and 4, it has been explained that the pentagonal prism-shaped cushioning material 51 can be formed by the paper piece 11, but according to this paper piece 11, not only the pentagonal prism-shaped cushioning material but also other shape cushioning materials can be used. Can be formed.

  5 to 7 are diagrams showing various cushioning materials that can be formed by the paper piece 11.

  5A and 5B are views of the above-described pentagonal cushioning material 51, where FIG. 5A is a plan view thereof and FIG. 5B is a perspective view thereof.

  FIGS. 6A and 6B are diagrams of a triangular prism-shaped cushioning material 52 formed by the paper piece 11. FIG. 6A is a plan view thereof, and FIG. 6B is a perspective view thereof.

  The triangular prism-shaped cushioning material 52 is formed as follows. That is, first, the paper piece 11 is not folded at the crease lines B1, B5, but is folded at the crease lines B2, B3, B4, and the first region R1 and the second region R2 are overlapped with the fifth region R5 and the sixth region R6. Then, a triangular columnar cylinder is formed. Further, the latching tongue piece G of the first region R1 and the latching tongue piece G of the fifth region R5 are folded inward (inward of the cylinder) while overlapping, and the latching tongue piece of the second region R2 is folded. G and the latching tongue piece G in the sixth region R6 are folded inward (inward of the cylinder) while being overlapped. As a result, the first region R1 and the second region R2, and the fifth region R5 and the sixth region R6 are maintained in an overlapped state. In this way, the triangular prism-shaped cushioning material 52 is completed.

  FIGS. 7A and 7B are views of a triangular prism-shaped cushioning material 53 formed by the paper piece 11, where FIG. 7A is a plan view and FIG. 7B is a perspective view thereof.

  The triangular prism-shaped cushioning material 53 is formed as follows. That is, first, the paper piece 11 is bent at all the crease lines B1, B2, B3, B4, and B5, and the first region R1 is overlaid on the sixth region R6. Further, the latching tongue piece G in the first region R1 and the latching tongue piece G in the sixth region R6 are folded and folded in either direction. Then, the first region R1 and the sixth region R6 are maintained in a state where they are overlapped.

  As described above, the square value of the lateral width W3 of the third region R3 is substantially equal to the sum of the square value of the lateral width W1 of the first region R1 and the square value of the lateral width W2 of the second region R2. The square value of the lateral width dimension W4 of R4 is substantially equal to the sum of the square value of the lateral width dimension W6 of the sixth region R6 and the square value of the lateral width dimension W5 of the fifth region R5.

  Therefore, the triangular prism-shaped bottom formed by the first region R1, the second region R2, and the third region R3 forms a substantially right triangle. In addition, the triangular prism-shaped bottom formed by the fourth region R4, the fifth region R5, and the sixth region R6 also forms a substantially right triangle.

  The angle formed by the first region R1 and the second region R2 is substantially a right angle, and the angle formed by the fifth region R5 and the sixth region R6 is also a substantially right angle. Further, the lateral width W1 of the first region R1 and the lateral width W6 of the sixth region R6 are substantially equal. Therefore, in the buffer material 53, the surface of the second region R2 and the surface of the fifth region R5 exist on the same plane. Therefore, the buffer material 53 has a triangular prism shape.

  As can be understood from FIGS. 5 to 7, the paper piece 11 is bent at any one of the five crease lines B1, B2, B3, B4, and B5 formed on the paper piece 11, and any region and any region. Depending on whether or not, the buffer material of various shapes can be formed.

  As described above, it has been shown that various cushioning materials can be formed by one piece of paper 11. However, by combining a plurality of such cushioning materials, various shapes of cushioning materials can be formed.

  8 and 9 are diagrams showing various cushioning materials formed by combining a plurality of cushioning materials.

  FIG. 8 is a diagram of a quadrangular prism-shaped cushioning material 54 formed by combining two cushioning materials 53a and 53b having the same structure as the cushioning material 53 shown in FIG. 7, and FIG. FIG. 2B is a perspective view thereof.

  The engagement tongue piece G in the second region R2 of the cushioning material 53a and the latching tongue piece G in the fifth region R5 of the cushioning material 53b are folded and overlapped, and further, the engagement of the fifth region R5 of the cushioning material 53a. The tongue piece G and the locking tongue piece G in the second region R2 of the cushioning material 53b are bent while being overlapped. As a result, the buffer materials 53a and 53b are coupled to each other, and the quadrangular prism-shaped buffer material 54 is formed.

  9 is formed by combining the buffer material 51a having the same structure as the buffer material 51 shown in FIG. 5 and the two buffer materials 53a and 53b having the same structure as the buffer material 53 shown in FIG. 5 is a plan view of a prismatic cushioning material 55. FIG. The three cushioning materials 51a, 53a, 53b are coupled to each other by the locking tongue piece G, so that a pentagonal prism-shaped cushioning material 55 is formed as a whole.

  In this way, by combining a plurality of cushioning materials formed by the paper piece 11, cushioning materials of various shapes and sizes can be formed. Since the locking tongue piece G is formed in each region of the cushioning material, various coupling forms can be adopted when coupling a certain cushioning material to another cushioning material. There are an infinite number of cushioning material shapes that can be formed by a combination of a plurality of cushioning materials.

  In the above, the buffer material of the various shapes which can be formed using the paper piece 11 was demonstrated.

  The heights of the cushioning materials 51, 52, 53, 54, and 55 shown in FIGS. 5 to 9 are all S1. However, when it is desired to obtain a cushioning material having a height higher than this, the paper piece 12 may be used instead of the paper piece 11 (see FIG. 2). By using the paper piece 12, a cushioning material having a height of S2 can be formed. Further, when it is desired to obtain a buffer material having a higher height, the buffer material sheet piece 10 may be used without being cut at the perforation line 41 (see FIG. 1). As a result, a cushioning material having a height of S0 can be formed.

  In addition to combining a plurality of cushioning materials having the same height, it is also possible to combine a plurality of cushioning materials having different heights. For example, the cushioning material having the height S1 formed by the paper piece 11 and the cushioning material having the height S2 formed by the paper piece 12 can be combined using the locking tongue pieces G of the respective cushioning materials.

  As described above, the buffer material sheet 10 (see FIG. 1) has a substantially rectangular shape. In addition, the shock-absorbing paper piece 10 is not formed with a protrusion or a notch. Since the buffer material sheet piece 10 is formed with a plurality of locking tongue pieces G, the buffer material sheet piece 10 can be assembled as a buffer material even if no protrusion or notch is formed. Since the shape of the shock-absorbing paper piece 10 is substantially rectangular and it is not necessary to form protrusions or notches, the shock-absorbing paper piece 10 can be manufactured from cardboard base paper without producing many missing parts. it can.

  In the above, the cushioning material paper piece 10 which is one embodiment of the present invention has been described.

  In the said embodiment, the buffer material paper piece which has the latching tongue piece formed by the notch from an upper side, and the latching tongue piece formed by the notch from a lower side was demonstrated. However, the buffer material sheet piece may have only a locking tongue piece formed by cutting from the upper side or only a locking tongue piece formed by cutting from the lower side. This is because the cushioning paper sheet piece can be formed as a cushioning material such as a triangular cylinder only by the coupling of the locking tabs on the upper side or the coupling of the locking tabs on the lower side.

  Moreover, although the said embodiment demonstrated the buffer material paper piece made from a cardboard, the buffer material paper piece may be made from paperboard.

  Moreover, although the substantially rectangular buffer material paper piece was demonstrated in the said embodiment, a substantially square shape may be sufficient.

  Moreover, although the said embodiment demonstrated the buffer material paper piece in which 6 area | regions are formed with five crease lines, the number of crease lines is not restricted to five. The number may be smaller (for example, 3 or 4), or may be larger (6 or more).

  In the above-described embodiment, the cushioning paper sheet having one perforation line has been described. However, it is not always necessary to provide the perforation line.

  Further, a larger number of perforation lines parallel to the upper side may be formed. Then, it becomes possible to divide into more pieces of paper. Further, depending on which perforation line is used for cutting, buffer materials having various heights can be formed.

  According to the present invention, in producing the buffer material paper piece, the number of dropping parts from the base paper is reduced, and the buffer material paper piece can be assembled as a buffer material of various shapes. Is beneficial in
