Definitions

  • This invention relates to dispensers for flowable compositions which use disposable cartridges of which one type is described in European Patent No. 0059413, and another type is disclosed in United States Patent No. 4,182,264.
  • Cartridges of the type disclosed in said European patent, and referred to herein as "cartridges of the first type" are normally of plastics material and comprise an elongated hollow body for receiving the composition to be dispensed, and at one end they have a discharge outlet and at the other end they have or are for receiving a piston which, when displaced along the interior of the cartridge body displaces the composition out of the discharge outlet into a bore which lies transversely to the length direction of the cartridge body.
  • This transverse bore is for receiving a nozzle tube, the nozzle tube having a tube body which is received in said bore, and is arranged to receive the displaced composition and to discharge it to a nib end of the nozzle tube from which the composition ejects laterally of the cartridge into, for example, a crease of a garment, the composition in such case being crease setting composition.
  • U.S. Patent Serial No. 4,182,264 there is disclosed an applicator for depositing a crease setting composition on the line of an intended crease or an actual crease in a textile fabric or garment, the applicator comprising a cartridge of the second type for the composition, with associated nib end, a rotatable member arranged so as to be engageable with the fabric or garment surface on both sides of the crease line and rotatable by a relative movement between the surface and the applicator, and a mechanism responsive to rotation of the member to urge the composition from the reservoir through the nib end.
  • the said cartridges of the first type, with a nozzle tube can be fitted to the applicators of U.S. Patent No. 4,182,264 and can be used in like fashion.
  • the applicator may be adapted to be driven by gas under pressure which is used for expelling the composition through the nib end.
  • the nozzle tube as disclosed in said European Patent is a metallic component which is push fitted into the transverse bore.
  • the cartridge When the cartridge is exhausted of composition it is disposed of, but the nozzle tube is removed and cleaned so that it can be re-used.
  • the present invention is concerned with the provision of a disposable nozzle tube, and in accordance with the invention there is provided a nozzle tube for use with a flowable composition cartridge of the first type and comprising
  • the nozzle tube has an end which is of non-circular shape, which engages a section of the transverse bore which is of similar shape in order to align the nozzle tube with the cartridge body, and also to prevent the nozzle tube from turning in use.
  • the nozzle tube includes a plug closing the end of the nozzle tube portion remote from said nib portion, and the nozzle tube may include a cranked portion so that the nib portion will lie at the desired angle relative to the crease.
  • the plug may have a rib and the tube portion may have a slot receiving said rib to ensure that the flat of the plug lies in the same plane as the flat on the tube portion.
  • the nib portion has a cap portion which receives the end of the tube portion, said cap portion being connected to the end of the tube portion received therein.
  • the cartridge or the dispenser is provided with a guide means which runs in the crease, said guide extends close to the nib portion, and said nib portion is provided with engagement means which fits to the guide means in order to keep the nib portion in alignment with the guide means and to enhance the rigid support of the nib portion.
  • a complete applicator or dispenser is shown in Figs. 1 and 1A and comprises a body 10 in which is rotatably mounted a two flange roller 11 which incorporates a worm gear 12.
  • a threaded rod 13 passes slidably through the body 10 and carries an internally threaded and externally toothed annular pinion 14, the external teeth of which mesh with worm gear 12 and the internal teeth of which engage with threaded rod 13.
  • a mounting block 15 surrounding the rod 13 and adjacent the body 10 has a cylindrical portion 16 over which a disposable plastics material cartridge 17 containing crease setting composition to be dispensed is removably fitted. The cartridge 17 is locked by a pivoted locking member 18.
  • a rocking link 20 is pivoted on block 15 at 21 and has a surface 20A acting against a pin 22 on the body so that rocking of the link causes the body 10 to be brought into greater proximity with the block 15 in the direction of arrow X against the action an an internal spring.
  • Fig. 1A shows how the two flanges of roller 11 engage the edges of a table member 12A having a central groove 13A.
  • a garment 14A with a crease therein e.g. a trouser leg is trapped between the roller 11 and table member 12A so that the crease lies in said groove 13A and exactly registers with a nozzle tube as explained herein so that as the applicator is moved in the direction of arrow X; crease setting composition is exuded from the nozzle tube into the crease in a controlled fashion.
  • the cartridge 17 is better seen in Figs. 2 to 4 and comprises a body including a hollow cylindrical portion 25 which is open at one end but is provided at the other end with a nozzle tube supporting body in the form of a transverse dispensing housing 26 which is of rigid plastics material and is much thicker than the cylindrical portion 25, and is also formed with a transverse bore 27 extending perpendicularly to the longitudinal axis of the portion 25 intersecting the interior of the body at a discharge opening 28.
  • the opening 28 is of circular shape and the interior of the portion 25 is conical at the nozzle end.
  • the bore is made to intersect the apex of the cone so that the diameter of the discharge opening 28 is less than the diameter of the bore 26.
  • the body is preferably moulded integrally with the housing (which is solid plastics material) from a suitable synthetic resin, such as polypropylene.
  • a suitable synthetic resin such as polypropylene.
  • An integrally mounted flange 29 with fins 29A at the open end of the body strengthens the end and provides convenient purchase when fitting the cartridge to and removing it from the applicator mechanism.
  • a hole 31 is provided to receive the locking member 18 to retain the cartridge in position.
  • a piston seal 32 of generally conical form is slidable but is a tight fit inside the body 17 and serves as a closure for the open end of the body to retain the contents of the body out of contact with the air.
  • the seal 32 may be of the non-reversible type to prevent the cartridge from being re-filled. It is shaped to co-operate with the piston body 23 when the latter is inserted into the cartridge as the cartridge is fitted to the dispenser mechanism, and then serves to expel composition from the body as the piston 23 is driven along the body by the applicator mechanism, in the manner as described in the said U.S. patent.
  • Fig. 2 shows that according to the arrangement in the said European Patent, the cartridge is sealed during storage by a closure plug or peg 33 (fig. 2A) which is a tight fit in the bore 27 and thus closes off the opening 28.
  • the peg is in fact made of a somewhat less rigid material than the body 26, for example being moulded from plasticised polyvinyl chloride, and therefore the plug 33 bulges into the opening 28 and thus will form an excellent seal at the opening 28.
  • the cartridge 17 When the known applicator is to be used, the cartridge 17 is fitted on the block 15 and locked into position by member 18.
  • the piston 23 is then advanced down the body 25 by rotation of threaded rod 13 until it engages and then seats firmly in the seal 32.
  • the peg 33 is then removed from the bore and replaced by a steel nozzle tube 34 which simply plugs into the end of the bore 26 as shown in Fig. 2B.
  • the tube 34 is closed at its upper end, but at its lower end it is formed with a broadened nib portion 36 terminating in a straight, narrow slot.
  • Fig. 1A shows how the nib portion 36 registers with the table groove 13A, which is important for the accurate dispensing of the composition.
  • An opening in the side wall of the tube 34 is provided at a position where it will register with the opening 28 into the body 25.
  • the applicator is then ready for use, but a desirable degree of pressure on the contents of the cartridge can be applied by actuating the rocking link 20.
  • a pneumatic actuator may be used for driving a piston member 32 along the inside of the cartridge body 25.
  • the body portion 50 is provided with an access aperture 74, corresponding to and which registers with aperture 28 to enable composition to flow from the interior of the body 17 into the body portion 50.
