PROBLEM TO BE SOLVED: To provide a paper container for receiving and volatilizing aromatic, the paper container having rigidity, facilitating handling, enabling adjustment of the amount of volatilization, and enabling compacting after use thereof.SOLUTION: A double paper container includes two paper containers configured by bonding one end of a fan-shaped barrel material while being superposed on the other end to form a cylindrical body, curling outward a larger opening port of the body to form a curled section resulting in forming a top section, and bonding a bottom member to a small opening port to form a bottom section. In the double paper container, one paper container is provided inside the other paper container to form an inside paper container and an outside paper container, respectively. The inside paper container is sealed tightly by sealing the curled section with a lid material. The body section includes at least one inside opening forming section formed by an incising line. The outside paper container includes at least one outside opening capable of forming the inside opening forming section and a vent hole in the body.COPYRIGHT: (C)2014,JPO&INPIT【課題】芳香剤を収納し揮散させる容器であって、剛性を有し、取り扱いがし易く、揮散量の調節が可能で、かつ使用後も減容化ができる紙容器を提供することにある。【解決手段】扇形状の胴部材の一方の端部を他方の端部に重ね合わせ接合して筒状の胴部を形成し、該胴部の大きい開口口の端部を外側にカールしてカール部を形成し天部が形成され、小さい開口口に底部材を接合し底部が形成された紙容器を、二つ具備する二重紙容器であって、一方の紙容器を、他方の紙容器の内に設け、それぞれ内紙容器と外紙容器とし、前記内紙容器が、前記カール部を蓋材にてシールし密封され、胴部に、切り込み線により形成された内開口部形成部を一つ以上備え、前記外紙容器が、胴部に、前記内開口部形成部と通気口を形成し得る外開口部を一つ以上備えたことを特徴とする二重紙容器である。【選択図】図3
