IMPROVEMENTS RELATING TO CARTRIDGES FOR DISPENSING FLUENT MATERIAL

摘要

The invention provides a cartridge (10) for dispensing fluent materials into creases of garments to render them more permanent. The cartridge comprises a plastic elongated body (50) having an integral tongue (16) projecting laterally of the body at one end and through which the fluent composition (40) is dispensed by passing a piston (32) along the inside of the body. The tongue is a narrow member and is aligned with integral laterally projecting fins (18, 20) which fit into the crease of a garment to be rendered permanent. The tongue has a narrow rectangular bore into which fits a nozzle also having a narrow rectangular bore. The tongue bore and the nozzle bore are aligned with the fins, so as to provide maximum exactness in alignment of the body, crease and ribbon of composition which is dispensed from the nozzle. The design maximises application efficiency by ensuring registry with the crease and nozzle. The invention also discloses other aspects of the cartridge including a means for preventing refilling and an improved arrangement of a cartridge adapted so that the piston is propelled by compressed air.
