2. Description of the Related Art Conventionally, as a buffer packaging material for various instruments such as automatic faucets, devices and other products, a foamed resin molded article such as styrene foam has been generally used. It is a target. However, for products that cannot be received on one side only, or when the number of parts is reduced due to the destination or product specifications, products that cannot be used with a four-point corner cushion pad in terms of strength are used for exterior packaging. A combination of a lower cushioning material corresponding to substantially the entire bottom of the case and an upper cushioning material corresponding to substantially the entire top of the case, each integrally molded with a foamed resin,
Alternatively, in many cases, a combination of the lower cushioning material formed by integral molding and the upper cushioning material separately formed in two portions disposed on opposite sides is used.

However, the lower cushioning material and the upper cushioning material integrally formed as described above use a large amount of resin,
There are drawbacks that lead to mass consumption of petroleum resources, high material costs, and bulky bulky handling.

[0004] Therefore, it is desired that this type of cushioning material minimize the amount of foaming resin used and have sufficient cushioning properties and shape retention strength in use.

As a cushioning wrapping material for solving such a problem, there has been proposed a structure having a structure in which separated and formed cushioning materials are attached to opposing sides of a support bottom plate at an interval (for example, Japanese Utility Model Application Laid-Open Publication No. H10-163686). 58-180167, Japanese Utility Model Application Laid-Open No. 62-34.
No. 64).

However, in each of these cases, the cushioning material is attached to the support bottom plate, which makes the attaching operation troublesome, and depending on the stored articles, the cushioning material may float from the bottom plate. There is a problem that the stability is poor, the bending strength of the support bottom plate itself is poor, and sufficient strength to withstand a drop test cannot be obtained.

[0007] The present invention has been made in view of the above,
In order to reduce the amount of resin used, two sets of cushioning materials are arranged at intervals on opposite sides in the outer case,
In addition, the two sets of cushioning materials can be reliably held at a fixed interval by the reinforcing connecting material arranged between them, and have sufficient strength to withstand the drop strength, so that they can sufficiently withstand their use. To provide.

[0008]

According to the present invention, there is provided a cushioning wrapping material comprising upper and lower pads made of a synthetic resin foam, which are vertically opposed to each other and hold an article to be wrapped therebetween. A combination of two sets of cushioning materials arranged at intervals on opposite sides in the case and a reinforcing connecting material interposed between the two sets of cushioning materials, wherein the reinforcing connecting material is a cardboard cardboard. A three-dimensional shape with a height approximately equal to or slightly lower than the height of the upper and lower pads is formed by a paperboard or other stiff sheet material, and the opposing surfaces of the two sets of cushioning materials are respectively
Continuous by combining both pads on the lower pads
A fitting recess forming a recessed portion is provided, and both end portions of the reinforcing connecting member are fitted into the fitting recess and held between the two cushioning members.

[0009] In the above, the two sets of cushioning materials have a protruding edge formed at the lower end of the fitting recess of the lower pad and the upper end of the fitting recess of the upper pad, respectively. It is particularly preferable that the pad is formed so as to be sandwiched from above and below by the protruding edge of the pad.

The reinforcing connecting member has a three-dimensional shape having a substantially concave cross section having a bottom plate portion and a winding portion formed by winding a continuous portion from the bottom plate portion into a rectangular tube shape. The upper pads of both cushioning members are provided with two fitting recesses into which the ends of the winding portions on both sides are fitted, and a convex portion between the two fitting recesses is sandwiched between the winding portions of the reinforcing connecting member. It is also possible to adopt a configuration in which it is inserted.

[0011]

According to the above cushioning packaging material, the two lower pads of the two sets of cushioning materials are arranged separately at opposing sides in the outer case, and the lower pads are opposed to each other. The end of the reinforcing connecting member having a three-dimensional shape is fitted into the fitting concave portion provided on the surface. Then, the article to be packaged is housed by being fitted into a housing recess provided on the upper surface of both pads. Those having a length are stored so as to be bridged over both pads. Thereafter, the upper pad of both cushioning materials is brought into contact with the lower pad, and the article to be packaged is held between the upper and lower pads. Also, at this time, the fitting concave portion provided on the opposing surfaces of the upper pads is fitted to the end of the reinforcing connecting member, thereby holding the reinforcing connecting member interposed between the opposing surfaces of both cushioning members.

The movement is restricted by the three-dimensionally shaped reinforcing connecting member fitted and held in the fitting concave portion forming a continuous concave portion between the two . Further, the reinforcing connecting member between the cushioning members is strong against bending due to its three-dimensional shape, so that bending between both cushioning members can be prevented, and both cushioning members can be reliably held at a constant interval, and the drop strength It has enough strength to withstand the test.

In particular, when the reinforcing connecting member fitted into the fitting concave portion is sandwiched from above and below by the protruding edges provided at the upper and lower ends of the fitting concave portion, the reinforcing connecting material during transportation can be reduced. The connected and combined state can be favorably maintained without fear of floating or the like.

Further, the reinforcing connecting member is formed into a three-dimensional shape having a rectangular cylindrical winding portion on both sides, and the winding portion is fitted into the two fitting recesses of the upper pad. When the convex portion between the fitting concave portions is sandwiched between both winding portions, the bonding strength between the reinforcing connecting material and the upper and lower pads is increased, and the shape-retaining strength is further increased by the reinforcing action of the winding portion. The cushioning material can be securely fixed to both sides in the outer case.
