Tintenpatrone und Lademechanismus für die Tintenpatrone

摘要

An air impermeable but soft polypropylene ink cartridge 1 has reinforcing ridges 6 projected from corner portions of peripheral walls 2,3 and a thick-walled opening end edge 4. A cover 20 is sealed to the cartridge by welding and has longitudinal ridges 21 formed on an inner surface thereof, and shape retaining ridges (23,Fig.3(a)) which project integrally from an outer surface of the ridges 21 so as to engage the body walls, so that deformation of the cartridge is suppressed during welding - any burrs thus formed are collected in a groove 25 of the cover. A cartridge (120,Fig. 12(a)-(d)) may be loaded onto a carriage without breaking an ink supply needle (119) by engaging a recess 15 in the lower surface of the cartridge with a support rod (117) of a lifter (115), and closing a pivotable carriage cover body (110) while guiding the lifter with a guide groove (106) parallel to the axial centre of the needle.
