Definitions

  • This invention relates to a cartridge of adhesive for use in an adhesive dispensing machine and in particular, though not exclusively, to a cartridge of tiling adhesive for securing tiles to a substrate.
  • a cartridge holding an adhesive as described above is not suitable for use in tiling a wall or floor, since the volume of adhesive within the cartridge would be sufficient for only very few tiles.
  • Pre-mixed adhesive for tiling often is supplied in tubs holding typically 10 or 15 litres but must be applied manually to the surface to be tiled. This is usually done by trowelling the adhesive on to the surface, spreading the adhesive and then scraping it into a series of parallel beads using a toothed spreader. This takes significant skill in order to generate uniformly spaced beads of more or less constant profile and also is relatively time consuming.
  • a cartridge of adhesive for use in an adhesive dispensing machine comprising a substantially cylindrical reservoir having an open end and a discharge end provided with an end wall formed with a neck, a piston slidably mounted in the reservoir for discharging adhesive through the neck, a first catch disposed internally at the open end of the reservoir to restrain the piston from leaving the reservoir through the open end thereof, and a second catch disposed internally adjacent the discharge end of the reservoir to restrain the piston adjacent the end wall once moved there to discharge the adhesive.
  • the first catch may comprise at least one projection formed in the open end of the cylindrical reservoir, either at the end of the reservoir or immediately adjacent that end.
  • the projection may be wholly continuous and thus in the form of an annular rib, or may consist of a series of individual ribs, each extending circumferentially for a limited extent, so long as there are sufficient ribs to prevent removal of the piston once inserted into the reservoir.
  • the annular rib or each projection advantageously is barb-shaped in cross-section, to permit the piston to be inserted into the reservoir by being snapped past the projection, but which projection then prevents removal of the piston rearwardly out of the reservoir.
  • the second catch may be similarly formed to the first catch and so may comprise at least one projection or an annular rib formed in the reservoir, but spaced from the discharge end of the reservoir by a distance not less than the axial thickness of the piston, so that the piston may be moved fully to the discharge end of the reservoir but then may not be moved rearwardly again.
  • a cartridge having a volume of perhaps 15 litres will be relatively heavy, when filled with tiling adhesive.
  • a handle arranged either at the open end or the discharge end of the reservoir.
  • Such a handle may preclude the insertion of the cartridge into a holder provided as a part of a dispensing machine and so it is preferred for the handle to be removable from the cartridge.
  • the handle may extend from a removable cap for the discharge end of the cartridge and in this case the cap may have a relatively large external diameter, more or less equal to that of the reservoir itself, whereby the reservoir may be stood on the cap for filling and storage purposes.
  • the handle is connected to a pair of diametrically opposed tabs each projecting axially from the periphery of the reservoir and each having an opposed opening in which an end portion of the handle is received.
  • a removable seal may be attached to the mouth of the neck, at the discharge end of the reservoir, both to protect adhesive loaded into the reservoir from deterioration and to provide quality assurance for the end user.
  • Such a seal may comprise a foil sealed to the end of the neck, over the mouth.
  • a similar seal may be provided over the open end of the cartridge, once filled and the piston has been inserted into the reservoir.
  • air may be trapped between the surface of the adhesive and the piston.
  • air may be eliminated by providing an air release port in the piston; the port may be open during insertion of the piston to allow the escape of air as the piston is brought into engagement with the surface of the adhesive. Then, the port may be sealed to prevent escape of adhesive, or the port may be fitted with a valve which is closed, for this purpose.
  • a notch or keyway may be formed in the external surface of the reservoir, to allow the correct orientation of the cartridge when fitted to a dispensing machine. Such a notch or keyway may also be used to restrain the rotation of the cartridge during filling with adhesive or even perhaps while adhesive is mixed in the reservoir during the manufacture of the finished cartridge.
  • Figure 1 is a cross-section of a first embodiment of cartridge
  • Figure 2 shows a connector for a flexible hose, for use with the cartridge of Figure 1 ;
  • Figure 3 is a cross-section through an alternative embodiment of cartridge, shown connected to a flexible hose;
  • Figure 4 is a detail view on an enlarged scale of the neck region of the cartridge of Figure 3.
  • Figures 5 and 6 show the neck region of the cartridge of Figure 3, together with a foil seal for the mouth of the neck.
  • a tiling adhesive cartridge which comprises a moulded plastics material reservoir 10 having a cylindrical side wall 11 and an end wall 12. The end wall defines a central neck 13 which has external threads 14, for a purpose to be described below.
  • Rib 15 is at the open end 17 of the side wall 1 1 and rib 16 is adjacent the end wall 1 2, spaced therefrom by a d istance equal to the thickness of a piston 18, shown in part adjacent the rib 15, in broken lines.
  • the piston has a grooved peripheral wall and, when inserted into the side wall 11 , is a close sliding fit therein.
  • a closure 20 is fitted to the neck 13, that closure having a central cap 21 with an internally-threaded circular wall 22 engageable with the threads 14 of the neck 13, and also having an end wall 23.
  • An O-ring 24 is fitted into a groove formed at the junction between the walls 22 and 23 of the cap.
  • the cap is moulded integrally with the closure 20, the external periphery of which is of the same diameter as the side wall 1 1 , and a wire handle 26 is connected to that closure such that the cartridge may easily be handled by using the handle.
  • the cartridge may normally stand on the closure 20, both during filling (as shown in Figure 1 ) with adhesive and subsequently during storage.
  • the reservoir of the cartridge is filled with adhesive 28 from the open end 17 of the reservoir, with the reservoir standing on the closure 20.
  • the piston 18 is fitted into the side wall 11 , by being snapped past the annular rib 15 to the position shown in Figure 1 .
  • any air trapped between the surface of the adhesive and the piston is allowed to escape through a port 29 in the piston.
  • that port is closed by way of a taper plug 30, driven into the port.
  • an air valve may be fitted to the piston such that air may escape while the valve remains open and then, following assembly of the piston to the reservoir, the valve may be closed.
  • the closure 20 When the cartridge of Figure 1 is to be used in an adhesive dispensing machine, the closure 20 is removed from the neck 13. This allows the handle 26 to be discarded and also opens the mouth of the neck 13. The cartridge is then inserted into a holder therefor (not shown) and which forms a part of the dispensing machine, and a flexible hose 32 (Figure 2) is secured to the neck by means of a connector 33.
  • Th is connector has internal threads 34 for engagement with the threads 14 of the neck 13 and also has a central opening within which is rotatably received the end portion of the flexible hose 32. This allows the connector 33 to be turned to inter-engage its threads 34 with corresponding threads 14 of the neck, without the hose 32 also turning.
  • the connector 33 has an O-ring 35 to effect a seal to the end face of the neck 13.
  • Figures 3 to 6 show a second embodiment of cartridge which is generally similar to that described above, but which differs in certain details.
  • like parts with those of the first embodiment are given the same reference numerals.
  • the reservoir 36 differs from that of the first embodiment in that the neck 37 is provided with internal threads 38 for receiving a connector 39 of a flexible hose 40, and is closed by a foil 41 ( Figures 5 and 6) heat-sealed to the end face of the neck. Before filling, the foil is sealed to the neck but when the cartridge is to be used, the foil is stripped away from the neck so opening the reservoir. Then, the connector 39 may be threaded into the cartridge neck, to allow adhesive to be driven out of the reservoir into the flexible hose 40.
  • FIG. 3 Also shown in Figures 3, 4 and 5 is an O-ring 42 fitted into an external groove 43 formed around the neck 37.
  • the O-ring effects a seal to that holder both locating the cartridge and preventing leakage of adhesive, as shown on the left hand side of Figure 4, where part of the holder is diagrammatically illustrated at 44.
  • F ig u re 3 also shows a wire hand le 45 con nected to a pa ir of diametrically opposed tabs 46 projecting from the end wall 12 of the reservoir. Those tabs typically have openings into which the end portions of the handle are pressed. When the cartridge is to be used, the handle 45 is pulled away from the tabs 46 and is discarded, such that the handle does not interfere with the fitting of the cartridge to the dispensing machine. Also as shown in Figure 3, the handle could instead be fitted to the open end of the reservoir, tabs 47 being instead provided for that purpose.
  • the piston 48 of the second embodiment is shown having a valve 49 fitted to a port 50 extending therethrough, for the same purpose as has been described above with reference to port 29 of the first embodiment.
  • the open end of the cylindrical side wall of the cartridge may be provided with a rectangular notch 53 as shown in Figure 7, for engaging a corresponding peg 54 within a cylindrical holder 55 for the cartridge.
  • a corresponding peg 54 within a cylindrical holder 55 for the cartridge.
