Description

本発明は、包装した内容物を固定できるようにして保管、輸送中における取扱時に破損したり損傷を受けるのを防止した紙箱に関する。   The present invention relates to a paper box capable of fixing packaged contents so as to prevent breakage or damage during handling during storage and transportation.

従来、段ボール箱等に包装した内容物を段ボール箱等の内面に取り付けたフイルムにより固定する包装材としては、例えば、特公昭５８−３９０４号に記載されているものが知られている（例えば、特許文献１参照）。上記の包装材は、品物を載置する面と、品物がほぼ封入される所定の大きさの空間を限定する対向して配置されたほぼ平行な側壁の対とを有する板材と、品物を載置する面と対向する側壁との合体部に隣接する部分、即ち、側壁の下部に沿ってホイルシートからなる熱収縮材の一端が接合されると共に他端が自由端の方へ伸長する少なくとも１枚のホイルシートからなる熱収縮材を備えた構成からなり、包装材の品物を載置する面に品物を載置して、品物の上に熱収縮材の伸長する部分を折り重ねて熱収縮させることにより、包装される品物の数や満たされる空間の大きさに関係なく、品物を固定できるようにした包装材である。しかしながら、この包装材の場合、ホイルシートからなる熱収縮材を側壁の下部に接着して取り付けられているので、包装材の載置面に載置された品物の上にホイルシートを折り重ねて熱収縮させた際に、ホイルシートの接着部が剥離して、側壁から分離してしまうおそれがあるために、品物を確実に固定することができないという欠点があった。
特公昭５８−３９０４号公報 Conventionally, as a packaging material for fixing a content packaged in a cardboard box or the like by a film attached to the inner surface of the cardboard box or the like, for example, the one described in Japanese Patent Publication No. 58-3904 is known (for example, Patent Document 1). The packaging material includes a plate member having a surface on which the product is placed, a pair of substantially parallel side walls arranged opposite to each other, which defines a space of a predetermined size in which the product is almost enclosed, and the product. At least one portion of the heat shrink material made of a foil sheet is joined along the lower portion of the side wall adjacent to the united portion of the surface to be placed and the opposite side wall, that is, the other end extends toward the free end. It consists of a heat-shrink material consisting of a single sheet of foil. The product is placed on the surface of the packaging material on which the product is placed, and the heat-shrink material stretches over the product to heat-shrink. Thus, the packaging material can fix the product regardless of the number of products to be packaged and the size of the space to be filled. However, in the case of this packaging material, since the heat shrink material made of a foil sheet is attached to the lower portion of the side wall and attached, the foil sheet is folded on the product placed on the packaging material placing surface. When heat shrinking, the adhesive part of the foil sheet may be peeled off and separated from the side wall, so that there is a drawback that the product cannot be fixed securely.
