<P>PROBLEM TO BE SOLVED: To provide a tetrahedral package body which is formed at a tetrahedral shape and can simply and surely open at a tearing-up state when opening a sealed package container and can utilize it as a container as it is when it is served for a meal after opening. <P>SOLUTION: An upper opening section is sealed by making end sections c, d of the upper opening section come in contact with each other on a bag material 2 which includes a bottom side ab and right and left side sides ac, bd and shows a rectangular shape on a plane, and a blocked section 3 arranged and crossed at right angles to a bottom side ab of the bag material 2 is formed. Thus, a tetrahedral container body 1 consists of a triangular bottom side face section A and a triangular upper side face section B which make the bottom side ab as one common side, and triangular right and left side face sections C, D which make the blocked section 3 as one common side. Further, an opening fracture tape 4 is pasted and arranged on an inner side face of the bag material 2 along an opening port 6 so as to form the opening port 6 which extends from end sections a, b of the bottom side ab to the end sections c, d of the upper opening section of the bag material 2 which are center sections of the blocked section 3. A handle 4A is connected with and formed at end sections a, b positions of the opening fracture tape 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
