Abstract

<P>PROBLEM TO BE SOLVED: To easily prevent a packaging box or the like from over-turning without reducing space efficiency during storage and transportation. <P>SOLUTION: In a pad 1 for preventing over-turning provided in the packaging box 21, coupling pieces 3 are connected to both sides of a base end of a rising piece 2 and stopper pieces 4 are connected to the outside of the respective coupling pieces 3 sequentially. Opposite ends of both coupling pieces 3 are inserted into a slit 27 provided on the bottom of the packaging box 21 so that they can be put in/out by slantly cutting outwardly from the center of the base end of the rising piece 2, making a base crease 5 at the border between the rising piece 2 and the coupling piece 3, and making an intermediate crease 6 from the center of the base end to the center of the tip of the rising piece 2. When pulled out from the slit 27, the rising piece 2 stands from the coupling piece 3 along the base crease 5 while bending in a V-shape along the intermediate crease 6 outside the packaging box 21. The opposite ends of the coupling piece 3 are butted and prevented from coming out of the slit 27 by the stopper piece 4. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

  The present invention relates to a flip-up prevention pad that can be freely inserted and removed to prevent the fall of a packaging box or the like having a small depth.

  In recent years, thin televisions such as liquid crystal televisions have a large screen size and a small depth. Therefore, the width of the end face corresponding to the depth of the television is also smaller in the packaging box than the width of the front and back surfaces. For this reason, when a packaging box containing a television is placed on a floor or a cargo bed in a standing state during storage or transportation, the packaging box may fall over even if it is touched slightly.

  In order to prevent such a packaging box from overturning, for example, a triangular cylindrical support leg as described in Patent Document 1 below is attached to the lower part of the front or back surface, which is the direction in which the packaging box is easy to overturn. It can be considered.

Japanese Utility Model Publication No.59-72971

  However, if the support legs as described above are attached to the packaging box, the packaging boxes cannot be arranged without gaps during storage or transportation, and there is a problem that the space efficiency in the warehouse or truck bed is reduced.

  Therefore, an object of the present invention is to make it possible to easily prevent the packaging box or the like from toppling over without reducing the space efficiency.

  In order to solve the above-described problems, the present invention provides a fall prevention pad provided on a support such as a packaging box, in which connecting pieces are sequentially provided on both sides of the base end of the undulating piece, and retaining pieces are provided on the outside of each connecting piece. Then, the opposite edges of the connecting pieces on both sides are cut obliquely outward from the base end center of the undulating piece, and a fold line is made at the boundary between the undulating piece and the connecting piece, and from the base end center of the undulating piece to the tip center Put a middle fold line, insert it in and out freely into the slit provided at the bottom of the supported object, pull it out from the slit, the undulating piece bends in a V shape along the middle fold line outside the supported object, It stands up from the connecting piece along the base fold line, the opposing edges of the connecting piece are abutted, and the retaining piece protruding from the connecting piece is prevented from coming out of the slit.

  Such a fall prevention pad is provided on a support such as a packaging box, and when the support is stored or transported, the fall prevention pad is pulled out from the slit of the support and the undulating piece is raised to prevent the fall. Because the pad is not pulled out of the slit and the raised piece is maintained by the load of the supported object, even if the supported object falls toward the raised piece, the supported object is dripped into the raised piece. It is possible to prevent the supported object from falling over.

  In addition, if the supported object is tilted slightly and the load on the supported object is released, the bent piece of the undulating piece extends and the undulated piece falls down while the connecting piece and the retaining piece that are abutted are separated from each other. The pad can be completely inserted inside the supported object.

  For this reason, during storage or transportation of the supported object, with the fall prevention pad completely inserted into the supported object, the supported object arranged at the back of the storage space is placed along the wall of the warehouse or loading platform, Sequentially arrange the supported objects to the front side without any gaps, pull out the fall prevention pad from the closest supported object, and raise the undulating piece, so that all the operations can be done easily without reducing the space efficiency. The supported object can be supported so as not to fall down.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2, the overturning prevention pad 1 is provided so as to be freely put in and out of a cardboard packaging box 21 for packaging a thin television.

  The packaging box 21 has a peripheral wall formed from a front plate 22, a back plate 23, and a pair of end plate 24, and overlaps flaps 25 and 26 extending from the lower end and the upper end thereof to form a bottom wall and a top wall. The width of the end face plate 24 corresponding to the depth of the television is smaller than the width of the front plate 22 and the back plate 23.

  A slit 27 is provided at the center of the lower end of the front plate 22, and the slit 27 is formed by cutting the flap 25 with the position shifted upward from the ridgeline between the front plate 22 and the flap 25 as a base end. Is opened by bending inward. At the center of the upper edge of the slit 27, a depressing piece 28 is cut and a pressing projection 29 is provided.

  The fall prevention pad 1 is formed from a cardboard blank as shown in FIG. In this blank, the connecting piece 3 is connected to both sides of the base end of the undulating piece 2, and the retaining piece 4 is connected to the outside of each connecting piece 3. Opposing edges of the connecting piece 3 and the retaining piece 4 on both sides are obliquely cut outward from the center of the base end of the undulating piece 2.

  A ruled fold line 5 is placed at the boundary between the undulation piece 2 and the connecting piece 3, and a fold line 6 is placed in the undulation piece 2 from the base end center to the tip center. At the boundary between the connecting piece 3 and the retaining piece 4, a side fold line 7 of a lead ruled with a cut intermittently connected to the stamped rule is entered.

  A stopper edge 8 is formed on the outer side of the end edge portion of the retaining piece 4 near the undulating piece 2, and a gap projection 9 is provided on the inner side through a step. Further, a finger insertion hole 10 is provided in the central portion on the front end side of the undulating piece 2.

  In order to use the fall prevention pad 1 for packaging a television in the packaging box 21, as shown in FIG. 3, the fall prevention piece 4 is folded on the upper surface of the connection piece 3 along the side folding line 7 to prevent the fall. The pad 1 is inserted from the outside to the inside of the packaging box 21 through the slit 27.

  Then, as shown in FIG. 4, when the retaining piece 4 completely enters the packaging box 21, the retaining piece 4 spreads outward due to the repulsion of the bent portion, so that the fall prevention pad 1 is prevented from coming off from the slit 27. The tip of the retaining piece 4 comes into contact with the back plate 23 and is prevented from entering the box.

  On the other hand, when a flat-screen television is packaged by the packaging box 21 with the fall prevention pad 1 inserted in this way and the packaging box 21 is placed on a warehouse or a truck bed, as shown in FIG. Slightly tilt the front side so that it floats, put your finger into the finger insertion hole 10, and pull out the fall prevention pad 1 from the slit 27.

  As a result, the undulation piece 2 rises from the connecting piece 3 along the base fold line 5 while the undulation piece 2 bends in a V shape along the middle fold line 6 on the outside of the packaging box 21, and as shown in FIG. When standing upright, the opposing edges of the connecting piece 3 and the retaining piece 4 are abutted, the stopper edge 8 comes into contact with the inner surface of the front plate 22 at the side of the slit 27, and the fall prevention pad 1 is prevented from coming off from the slit 27.

  At this time, the gap projections 9 are inserted into the gaps of the slits 27 formed on both sides of the undulating piece 2 to prevent the tipping prevention pad 1 from moving in the width direction, and the connecting piece 3 and the retaining piece. 4 is pressed from above by the restraining piece 28 and the pressing protrusion 29, so that the overturning prevention pad 1 is prevented from rattling in the vertical direction.

  In this way, when the fall prevention pad 1 is pulled out from the slit 27 to raise the undulating piece 2 and the inclination of the packaging box 21 is returned, as shown in FIG. Since the repulsion of the folding at the folding line 6 is suppressed and the standing state of the undulating piece 2 is maintained, even if the packaging box 21 tries to fall in the direction of the undulating piece 2, the packaging box 21 is dripped into the undulating piece 2. It is possible to prevent the packaging box 21 from falling.

  Further, when the packaging box 21 is slightly tilted so that the front side is floated and the load of the packaging box 21 is released, as shown in FIG. 2, the connected piece 3 and the retaining piece 4 that are abutted are separated by the repulsion of the fold. However, since the bending of the undulation piece 2 extends and the undulation piece 2 falls, the fall prevention pad 1 can be completely inserted inside the packaging box 21.

  For this reason, when the packaging box 21 is stored or transported, the packaging box 21 disposed at the innermost part of the storage space is placed along the wall of the warehouse or the loading platform with the fall prevention pad 1 completely inserted into the packaging box 21. The packaging boxes 21 are sequentially arranged on the front side without any gaps, and by pulling out the fall prevention pad 1 from the packaging box 21 that is closest to the front and raising the undulating pieces 2, a simple operation is performed without reducing space efficiency. Thus, all the packaging boxes 21 can be supported so as not to fall down.

  In the above-described embodiment, the case where the fall prevention pad 1 prevents the flat TV packaging box 21 from falling is exemplified. However, the fall prevention pad 1 can also be used to prevent falls such as partitions. In this case, it is preferable to provide a slit in the lower part of a vertical plate such as a screen, and pull up the undulating piece 2 on the opposite side of the stand.
