LIQUID STORAGE VESSEL, INKJET RECORDING APPARATUS USING LIQUID STORAGE VESSEL, AND MANUFACTURING METHOD FOR LIQUID STORAGE VESSEL

摘要

PROBLEM TO BE SOLVED: To prevent the thickness of the thinnest part of a protrusive sheet constituting an ink storage part of an ink tank from being decreased by its molding.;SOLUTION: A folded part 3A is formed on the protrusive sheet 3. The provision of the folded part 3A enables a molding depth in the molding to be almost dimidiated so that a protrusive shape is twice higher. Thus, a decrease in the thickness due to elongation in the molding is reduced, and the sheet is made as thick as possible.;COPYRIGHT: (C)2007,JPO&INPIT
