<P>PROBLEM TO BE SOLVED: To provide a spout of a paper container which is capable of being easily removed by the fingers of the hand for facilitating collection in collecting paper resources of the paper container with a spout, not does not permit mixture of different kinds of substance, and has an excellent liquid-tight performance. <P>SOLUTION: The spout includes a flange part having a mounting face provided on the outer periphery thereof to be welded or stuck liquid-tightly on an opening part of the paper container, a spout tube body formed of a pedestal part connected with the inner peripheral end of the flange part through a plurality of breakable bridges and a spout tube raised from the inner peripheral side of the pedestal part and a ring-shaped member weakly welded or weakly stuck on the lower end face of the pedestal part and the lower end face of the flange face to liquid-tightly close a plurality of space parts between the bridges. This ring-shaped member is formed of a material different from those of the spout tube body and the flange part. The bridges are broken to separate the ring-shaped member from the flange part, and thus removal together with the spout tube body can be done to solve the problem. <P>COPYRIGHT: (C)2010,JPO&INPIT |
