CORRUGATED FIBERBOARD INTERIOR MATERIAL AND ITS MANUFACTURING METHOD
To provide a corrugated fiberboard interior material capable of easily inserting male tongues into female tongues of another corrugated fiberboard interior material.SOLUTION: In a corrugated fiberboard interior material constituted by joining three corrugated fiberboards, a middle layer projecting part 20T forms a male tongue structure 40, and a surface layer projecting part 10T and a rear layer projecting part 30T form a female tongue structure 50, and at least one of a first inner part 10c of a liner on a middle layer corrugated fiberboard 20 side of a surface layer corrugated fiberboard 10, a second inner part 30c of a liner on the middle layer corrugated fiberboard 20 side of a rear layer corrugated fiberboard 30, a first outer part 20c and a second outer part 20d of a pair of liners of the middle layer corrugated fiberboard 20 are provided with curved parts 10m, 30m, 20m which curve in the direction in which the plate thickness of each projecting part becomes thinner toward the end in the projecting direction of each projecting part.SELECTED DRAWING: Figure 8
【課題】雄サネを、他の段ボール製内装材の雌サネに容易に挿入することが可能な段ボール製内装材を得る。【解決手段】三枚の段ボールが接合されることで構成された段ボール製内装材であって、中層突出部２０Ｔは雄サネ構造４０を形成し、表層突出部１０Ｔおよび裏層突出部３０Ｔは雌サネ構造５０を形成し、表層段ボール１０の中層段ボール２０側のライナーの第１内側部分１０ｃ、裏層段ボール３０の中層段ボール２０側のライナーの第２内側部分３０ｃ、中層段ボール２０の一対のライナーにおける第１外側部分２０ｃおよび第２外側部分２０ｄのうちの少なくとも一つには、各々の突出部の突出方向における端部に向かうにしたがって各々の突出部の板厚が薄くなる方向に湾曲する、湾曲部１０ｍ，３０ｍ，２０ｍが形成されている。【選択図】図８
