PROBLEM TO BE SOLVED: To enable cooling by soaking even a paper container into iced water or the like, by providing an outer packaging body, made of shrink film, onto the outside of the paper container filled with drink and sealed hermetically, the paper container being formed from a laminated material comprising a paper layer, as a main body, and by hermetically sealing the seal parts of the outer packaging body with water-resistant protective tapes. SOLUTION: A paper liquid container 10 which is filled with drink such as juice or coffee and sealed hermetically consists of a laminate material comprising a paper layer, as a main body, and heat-sealable resin layers, such as polyethylene, provided on both sides of it. Also, in order to enhance the preservability of the contents, a barrier material is disposed on the inside of the paper. The outside of such a paper liquid container 10 filled with the drink and hermetically sealed is covered with an outer packaging body 11 made of shrink film. Then, onto the surfaces of seal parts 12 formed on the top and bottom of the outer packaging body 11, water-resistant protective tapes 14 are stuck and fixed. In such a paper liquid container 10, deterioration of the strength of the paper 10 can be prevented even if it is directly cooled by being soaked in cool water, for example, iced water or the like. |
