Estimating the term…
The invention relates to a nozzle having a piercing projection for safe and efficient release of viscous material from a collapsible tube sealed at a front end and a rear end by tie clips when housed within a dispensing tool. The piercing projection extends from the nozzle interior surface. The piercing projection is arranged to pierce the front end of the collapsible tube along a tear line to form a flap of the collapsible tube to which the front end tie clip remains attached. An upstanding wall extends from the nozzle interior surface to define a retention shelf between the upstanding wall and the nozzle interior surface. The retention shelf is configured to receive and retain therein the flap and the front end tie clip during dispensing to enable unobstructed flow of the viscous material through the dispensing end opening.
A nozzle for dispensing a viscous material from a collapsible tube positioned on a dispensing device, the collapsible tube formed of a thin wall casing, the dispensing device having a compression assembly arranged to compress the collapsible tube towards the nozzle, the nozzle comprising:
A nozzle for dispensing a viscous material from a collapsible tube positioned within a dispensing device, the collapsible tube formed of a thin wall casing, the dispensing device having a compression assembly arranged to compress the collapsible tube towards the nozzle, the nozzle comprising:
A kit for converting a device for dispensing viscous material from a cartridge to a device for dispensing viscous material from a collapsible tube, the dispensing device including a carriage assembly arranged for housing the cartridge when configured for dispensing from the cartridge, and a drive member for moving an ejector in a forward direction, the kit comprising:
A dispensing device for dispensing viscous material from a cartridge which is convertible to a device for dispensing viscous material from a collapsible tube, the dispensing device including a carriage assembly arranged for housing the cartridge when configured for dispensing from the cartridge, and a drive member for moving an ejector in a forward direction, wherein components for converting the dispensing device include a rigid sleeve having a tubular thin-walled body portion, and a piston ring sized for fitting over the ejector and having an outer periphery configured to abut an inner wall of the rigid sleeve to provide a seal with the inner wall, wherein when the dispensing device is configured for dispensing from the collapsible tube, the collapsible tube and the piston ring are inserted into the rigid sleeve, the rigid sleeve is registered within the carriage assembly with the piston ring located adjacent the ejector, and the piston is fitted over the ejector to avoid pinching of the collapsible tube during dispensing.
