Description

  The present invention makes it easy to attach a basket composed of a net to a pallet, and once attached, the basket does not easily come off from the pallet, and it is also easy to put in and out a large plastic container containing a chemical solution. For mold box pallets.

  Conventionally, a net-type box pallet 100 in which a net basket is mounted on a pallet has been used as a means for storing and transporting dangerous materials such as chemicals because it is easily visible from the outside. In particular, the mainstream is that the door nets 101a and 101b have double doors because of ease of handling such as taking in and out of large plastic containers (Patent Document 1). However, there is a problem in strength because the mesh cage is composed only of a wire mesh, and there is a contrivance such as providing a bottom plate 103 separately from the pallet 102 and attaching both side nets 104 and 105 and a back mesh 106 to the bottom plate 103. It was.

Even if it is such a structure, the door nets 101a and 101b are hinged to the side nets 104 and 105, but the mesh cage is a wire net structure, so that the strength is insufficient and the door nets 101a and 101b scatter. In addition, there is a problem such as fixing the bottom plate 103 and the pallet 102 because it is necessary to provide the bottom plate 103, and handling is inconvenient. In addition, recently, a large plastic container containing powerful drugs or flammable drugs Since storage of such items has been carried out and strict management has been required, a sky net (in this case, none) is provided, and each net is fixed so that it is not easily separated. (Patent Document 1).
