Abstract

PURPOSE:To make a joining part having a strong structure against impact, by bending the joining part nearly parallel to the moving direction of molds and forming it to the side of a container. CONSTITUTION:Jointing parts 11A, 11B for forming a laminate material joining part of a pair of molds 10A, 10B which move to close and open along a straight line direction oppositely and form a container are provided so as to become parallel faces to the moving direction of the molds, and when molds being closed, jointing parts 11A, 11B are situated oppositely inside and outside respectively and a clearance W between jointing parts 11A, 11B is made to be in relation W<2t, being compared with a thickness (t) of a laminate material 20. Also, molds 10A, 10B have cutting parts 12A, 12B which are bent at a right angle outside from tips of jointing parts 11A, 11B and contact each other. Accordingly, improvement of cracking prevention is intended by making a pinch off part not to suffer tensile stress directly when being impacted.
