Improvements relating to cartridge for dispensing flueht material

Abstract

The invention provides a cartridge for dispensing fluent materials into creases of garments to render them more permanent. The cartridge comprises a plastic elongated body having an integral tongue projecting laterally of the body at one end and through which the fluent composition is dispensed by passing a piston along the inside of the body.The tongue is a narrow member and is aligned with integral laterally projecting fins 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.

Description

technical field [0001] The present invention relates to a cartridge and cartridge / nozzle assembly for applying fluid material into the creases of garments or fabrics. The cartridge and cartridge / nozzle assembly has an applicator aperture, and the fluid material has a viscosity such that a certain pressure is required to force the material to be extruded through the applicator aperture. Background technique [0002] Cartridges of this type have been known for at least fifteen years, and a now known cartridge is described in European Patent No. The ingredients that make up the fluid material) are applied to the creases of the garment, making the creases more durable. The original crease-setting composition was usually a synthetic resin-based material that was thermoset, so that it would cure when exposed to heat to make the crease more durable, but is now more commonly used as a natural-setting composition that Still resin based. The known cartridge comprises an elongated p...

Problems solved by technology

This causes a problem and requires a special connection

These connections are difficult to insert and remove properly, and operators find them difficult to use because they are tight or become tight quickly

[0011] Finally, if the mount to connect the air supply is made by using a detachable joint, then by removing the joint it is possible for the cartridge to be refilled

We do not recommend refilling the cartridge, as there will inevitably be residual resin in the cartridge that has cured from the first fill, and this will cause the cartridge to work inefficiently, leading to unsatisfactory results

Additionally, air can become trapped in the cartridge, causing resin quality issues, and for best results, a used cartridge should always be cleaned before being reused
