PROBLEM TO BE SOLVED: To obtain a simple smoking box being excellent in water resistance and strength, capable of being used in rainy weather and used repeatedly, enabling a state of smoking and an amount of smoke to be confirmed from outside without opening an observation hole, and capable of being downsized for carriage convenience.SOLUTION: The simple smoking box is made of a paperboard material 3 laminating a thermoplastic resin 2 on front/rear faces of a paper layer 1, forms a quadrangle-cylindrical trunk part 11 with trunk panels 7, 8, 9, 10, and forms an upper lid part 26 of the quadrangle-cylindrical trunk part 11 with upper lid panels 22, 23, 24, 25 arranged continuously to upper edges of the trunk panels 7, 8, 9, 10. The paper layer 1 contains water resistant additives and water repellent agents. A window hole 34 is formed in at least one of the four trunk panels and four upper lid panels and an observation hole 36 is arranged by bonding a through-view film 35 so as to cover the window hole 34. Folding vertical lines 37, 38 for folding are formed in center parts of the trunk panels 7, 9 on both lateral face sides and upper lid panels 22, 24 arranged continuously to the upper edges of the trunk panels 7, 9 on both lateral face sides.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 耐水性、強度に優れ、雨天時での使用や繰り返しの使用を可能にし、覗き窓を開けること無く外から燻製の状況や煙の量の確認等を確認することができ、持ち運びに便利な小型化を可能にした簡易燻製ボックスを得る。【解決手段】 紙層1の表裏面に熱可塑性樹脂2を積層した板紙素材3からなり、胴部パネル7,8,9,10で四角の筒状胴部11を形成し、胴部パネル7,8,9,10の上端に連接した上蓋パネル22,23,24,25で筒状胴部11の上蓋部26を形成する簡易燻製ボックスであって、紙層1は耐水化剤及び撥水剤を含有し、4つの胴部パネルまたは4つの上蓋パネルのうち、少なくとも1つのパネルに窓用穴34を形成し、窓用穴34を覆うように透視フィルム35を貼着して覗き窓36を設け、両側面側の胴部パネル7,9及び両側面側の胴部パネル7,9の上端に連接する上蓋パネル22,24の中央部に折り畳み用縦折線37,38を形成した。【選択図】 図1
