Description

  The present invention relates to a cushioning member, and more particularly to a cushioning member that positions a packaged item when it is stored in a packaging box and protects the packaged item from an external impact.

  When the packaged item is stored in the packaging box, a buffer member is disposed between the packaged item and the storage box in order to prevent the packaged item from rattling and to protect the packaged item from external impact. As shown in FIG. 5, an excellent buffering action was obtained by disposing the cushioning members 8a, 8b, 8c, and 8d made of a foam material at the four corners of the packaging box 6 (for example, Patent Document 1).

However, in response to the recent increase in environmental awareness, it is strongly desired from the market that the cushioning member can be recycled. The buffer member has been widely used (for example, Patent Document 2).
Japanese Patent Laid-Open No. 2003-237846 JP 2002-332071 A

  6 is packed with cushioning members 9a, 9b, 9c made of corrugated paper or the like on the inner bottom surface or inner wall of the packaging box 6, and the packaged material 7 is stored in the space between the cushioning members. Is. However, in such a packing method, the number of parts increases, and at the same time, an operation of attaching a buffer member to the packing box 6 is required, resulting in an increase in production cost and a decrease in productivity. In addition, there is a problem that it takes time to separate and disassemble the cushioning member from the packaging box 6 after use.

  The present invention has been made in view of such a conventional problem, and an object of the present invention is to be installed in a packaging box without increasing the number of parts and without using an adhesive or an adhesive jig. It is in providing a buffer member.

  It is another object of the present invention to provide a shock-absorbing member that can be easily assembled, maintains the assembled state during packaging, and can be easily returned to the expanded state after use.

  According to the present invention, the cushioning member is attached to the inside of the packaging box, and has a flat plate-like base portion in the unfolded state, a square-shaped punch hole is formed in a substantially central portion of the base portion, and the two opposite sides of the punch hole are formed. From each end, a notch is formed so as to be perpendicular to the two opposite sides and connected to the punched hole, and by deforming the base so that the two opposite sides are in contact with each other, the buffer part protrudes from the base. A cushioning member for a packaging box is provided.

  Here, from the viewpoint of positioning and shape maintainability at the time of storing the object to be packed, the shape of the buffer portion is preferably a rectangular parallelepiped shape.

  In addition, from the viewpoint of protecting the side surface of the article to be packed and fitting the buffer member tightly in the packaging box, it is preferable that a side wall portion is provided continuously on the side sides facing the base portion via folding lines. Then, from the viewpoint of further improving the buffering action, the second cut is formed so that it is perpendicular to the folding line and the central part thereof is located at the folding line, and at both ends and the center of the second cutting. Forming a second folding line in a direction perpendicular to the second cut and reaching the side, folding the side wall portion substantially perpendicular to the base portion, and folding the second folding curve to form the base portion It is preferable that second buffer portions are formed at both ends.

  In the shock-absorbing member of the present invention, by deforming the base so that the two opposite sides of the rectangular hole formed in the substantially central portion of the base are in contact with each other, the shock-absorbing portion is formed so as to protrude from the base. The work of attaching the buffer portion to the base portion with an adhesive becomes unnecessary, and the productivity is remarkably improved. In addition, it can be easily assembled as compared with the prior art, and can be easily returned to the expanded state after use, and the working efficiency is dramatically improved.

  Further, when the shape of the buffer portion is a rectangular parallelepiped shape, positioning and shape maintainability at the time of storing an object to be packed are improved.

  If the side wall portion is continuously provided on the opposite sides of the base portion via a folding line, the side surface of the packaged item can be further protected. At the same time, the shock-absorbing member can be fitted in the packing box. Further, a second cut is formed so as to be perpendicular to the folding line and the central part thereof is located at the folding line, and perpendicular to the second cutting at both ends and the center of the second cutting. Forming a second folding line extending in the direction and to the side, folding the side wall part substantially perpendicularly to the base part, and folding the second folding line so that second buffer parts are formed at both ends of the base part. If formed, the buffering effect can be further improved.

  Hereinafter, although the buffer member concerning the present invention is explained based on a figure, the present invention is not limited to these embodiments at all.

  FIG. 1 is a development view showing an example of a buffer member according to the present invention. FIG. 2 is a perspective view in the middle of assembling (deforming) the buffer member of FIG. In the buffer member of FIG. 1, a rectangular hole 11 is formed in a substantially central portion of the rectangular base 1. Cuts 12a, 12b, 12c, and 12d (generally referred to as “cuts 12”) are perpendicular to the two sides 111a and 111b at both ends of the two opposite sides 111a and 111b of the left and right sides of the punched hole 11. Is formed). By the cuts 12 and the cutout holes 11, crosspieces 10 a and 10 b are formed on both sides of the cutout holes 11. When the base portion 1 is deformed so as to close the punch hole 11, the crosspiece portions 10a and 10b protrude from the base portion 1 to form buffer portions 2a and 2b (shown in FIG. 2). The shapes of the buffer portions 2a and 2b are determined by the length (X) of the cut 12, the length (Y) of the side of the punched hole 11, and the bending position. The shape of the buffer portions 2a and 2b will be described later.

  On the other hand, side walls 3a and 3b are formed integrally with the base 1 on both the left and right sides of the base 1 via folding lines 41a and 41b. The second cuts 13a, 13b, 13c, 13d (collectively "second cut 13") are perpendicular to the folding lines 41a, 41b and the center portions thereof are located at the folding lines 41a, 41b. Are formed on both side portions of the respective side wall portions 3a and 3b. Valley fold lines (second fold lines) 42a and 42c and mountain fold lines (second fold lines) 42b reaching the side edges are formed at both ends and the center of the second cut 13.

  When the buffer member having such a structure is attached to the packing box 6 (shown in FIG. 3), the buffer member is deformed to form the buffer portions 2a and 2b. Specifically, as shown in FIG. 2, the left and right sides 111 a and 111 b of the punch hole 11 are brought into contact so as to close the punch hole 11 formed in the base 1. Then, the crosspieces 10a and 10b protrude from the base portion 1 to form the buffer portions 2a and 2b. In the buffer member of this embodiment, since the length (X) of the cut 12 is ½ of the deformation (Y) of the buffer member, the length (X) of the cut 12 is just the buffer portion 2a, Since the height is 2b, the buffer portions 2a and 2b are rectangular in side view.

  Then, the side wall portions 3a and 3b connected to the base portion 1 are bent substantially perpendicularly to the base portion 1 by folding lines 41a and 41b. At this time, the second buffer portions 5a, 5b, 5c, and 5d are formed at the four corners of the base portion 1 by being bent at the valley fold lines 42a and 42c at both ends of the second cut 13 and the mountain fold line 42b at the center portion. The

  FIG. 3 shows a completed assembly of the buffer member. Buffer portions 2a, 2b, 5a, 5b, 5c, and 5d are formed at the center and both ends of the opposite sides of the base 1. Then, the assembled cushioning member is inserted into the packing box 6. The outer shape of the base 1 of the buffer member is substantially the same as the inner bottom surface of the packing box 6, and the side surface of the buffer member is set to be the same as or slightly lower than the inner wall of the packing box 6. When inserted, the packing box 6 prevents the buffer member from returning to the expanded state, and the buffer member stably maintains the assembled state.

  And the to-be-packaged object 7 is inserted in the area | region between the buffer parts of the buffer member inserted by the packing box 6. FIG. The packed member 7 is positioned by the side surfaces of the buffer portions 2a, 2b, 5a, 5b, 5c, and 5d, and rattling is prevented. In addition, the shock absorbers 2a, 2b, 5a, 5b, 5c, and 5d absorb the shock against the external shock, and the packaged item 7 is prevented from being damaged.

  The shape of the buffer portion is not particularly limited, and may be determined as appropriate from the gap between the packed object 7 and the packing box 6, the shape, size, weight, and the like of the packed object. The shape of the buffer portion can be changed into various shapes depending on the length (X) of the notch 12 and the length (Y) of the side of the hole 11 shown in FIG. In the above-described embodiment, the buffer portions 2a and 2b have a rectangular parallelepiped shape. For example, as shown in FIG. ((B) in the figure) or an arc-shaped buffer part 23 ((c) in the figure) may be used. Further, the size (length) of the buffer portion is determined by the length (X) of the cut and the length (Y) of the side of the punched hole 11. Further, the wider the buffer portion, the higher the buffering effect, but the larger the outer shape of the packaging box. Therefore, the width of the buffer portion may be determined including the material of the buffer member in consideration of the outer shape of the packing box and the size / weight of the packaged item.

  Further, the material of the buffer member may be appropriately determined from the weight of the object to be packed, and examples thereof include cardboard paper and hard paper.

  In the embodiment shown in FIG. 3, the positioning and buffering action in the front-rear direction is achieved by one buffer member. However, another buffer member is arranged such that the buffer portion is positioned in the left-right direction in the drawing. Of course, it may be installed on the existing buffer member so as to achieve front-rear / left-right positioning and buffering action. Of course, the buffer member may have only the base portion without the side wall portion.
