Document Type and Number:
Japanese Patent JP2989028
Kind Code:
B2
Abstract:
PURPOSE: To form an opening part as if a paper is torn up with a ruler by providing a specific sticking or heat-sealing part, forming a boundary line part coincident with the tearing up direction of a seal-breaking part, and making both edges of an seal-breaking part with a boundary line in the vicinity of a folding part.
CONSTITUTION: In this developer container, the opening part 8 of a container main body 6 is sealed with a sealing member 9 and a heat seal 10, the sealing member 9 is turned down on a start end part 13 to overlap the unseal-operating part 12 on a sealing part 11, and the unseal-operating part 12 is pulled to tear up the seal-breaking part 16, in use. At this time, in the shape of the sticking or heat-sealing part 10 of the unsealing start end part 13 of the sealing member 9, the boundary line 18 of the sticking or heat-sealing part and a nonsticking or a nonheat-sealing part, which face each other, on the extension of the unsealing part 16 in its longitudinal direction, is provided, and the basal width of the seal-breaking part 12 is almost coincident with the interval of the boundary lines 18. Thus, the opening part 8 of desired equal width is formed on the sealing part 11 of the sealing member 9 with which the developer container is sealed.
