Abstract
A method for economically manufacturing a water-resistant paper container having a thermoplastic film coating on the inner and/or outer wall surfaces by means of an ultrasonic wave welding technique. The paper container can be economically manufactured by the utilization of an ultrasonic wave welding technique without the use of any adhesive. According to the method of the present invention, a bottom panel and a body member can be interruptedly joined together at the interface between the panel and the container body. As a result, the inner wall surface of the container can be easily and rapidly lined with a thermoplastic film by a known method. Furthermore, according to the present invention, a container mouth edge which is capable of resisting to any deforming stress can be formed.
