Title:
INK CARTRIDGE
Document Type and Number:
Japanese Patent JP3837877
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve a contacting property between an ink supplying needle and an elastic seal material and an airtight property therebetween after the pulling-out of the needle by a constitution wherein the elastic seal material is readily inserted into a cylindrical member so that the elastic seal material is made to be in the compressed condition.
SOLUTION: A cylindrical member 5 of an ink bag body 2 comprises an ink supplying hole 5a and a housing section 5b that houses an elastic seal material 6 made of a rubber. A total length of the elastic seal material 6 and a pressing member 7 in an axis direction is greater than a length of the housing section 5b in the same direction. The elastic seal material 6 is inserted into the housing section 5b and is compressed by the pressing member 7 in the axis direction so that the diameter of the elastic seal material 6 is extended, then it is brought into intimate contact with the inner wall of the housing section 5b. After that, the pressing member 7 is welded to the end face of the cylindrical member 5. Thereby, a compressing force of the elastic seal material 6 with respect to an ink supplying needle is raised, thus improving a contacting property between the ink supplying needle and elastic seal material 6 and an airtight property therebetween after the pulling-out of the needle.
