Definitions

  • THIS INVENTION relates to a sealing arrangement for adhesive dispensers and, more particularly, an arrangement for sealing adhesive dispensers without the use of rubber o- rings.
  • the sealing is carried out by first inserting a plug into the open end of the barrel of the dispenser after the barrel has been charged with produce, the plug having a rubber o-ring co-operating with the internal wall of the barrel to seal the adhesive within the dispenser from the atmosphere outside the plug. Mechanical pins are then forced between the rubber o-ring of the plug and the internal wall of the barrel. Any air trapped between the adhesive or resin and the plug is bled from around the sides of the rubber o-ring which recovers its full sealing capability once the pins are withdrawn.
  • a further disadvantage of the above prior art methods is that it is difficult to ascertain when all the air trapped between the adhesives or resin and the sealing plug in the barrel has been removed. With many adhesives or resins it is imperative to remove all the air in order to stop the adhesive or resin from reacting with the air and undergoing an irreversible transformation.
  • the present invention aims to overcome or at least mitigate the above problems presented by the prior art by providing a sealing arrangement which will not damage the internal wall of the dispenser barrel and does not react with an adhesive or resin within the dispenser.
  • the invention provides a sealing arrangement for sealing a dispenser having a cylindrical barrel with an open charging end through which a flowable product is introduced into the dispenser, which arrangement comprises a plug for inserting into the barrel after introduction of the product and formed with a bleed aperture through which air trapped between the plug and the product escapes, and a stopper engagable with the plug to seal the aperture in the plug without forcing air back through the plug and without allowing the contents of the dispenser to escape.
  • a method of sealing a dispenser having a cylindrical barrel with an open charging end through which a flowable product is introduced into the dispenser comprising the steps of introducing into the open end of the barrel a sealing plug with a bleed aperture through which the air trapped between the plug and the product escapes, and engaging a stopper with the plug so that no air is forced back through the plug and no product escapes through the plug, and locking the second sealing member in engagement with the first sealing member.
  • an apparatus for introducing a sealing arrangement as described above into a dispenser having an open charging end through which a flowable product is introduced into the dispenser comprises: means for storing sealing arrangements to be inserted into successive dispensers; means for supplying a charged dispenser to a capping station of the apparatus and for supporting the dispenser in the capping station; means for feeding a sealing arrangement from the storing means to the open charging end of the dispenser; means for inserting the plug of the sealing arrangement into the dispenser, and means for engaging the stopper of the sealing arrangement after insertion of the plug in the dispenser.

  • a sealing arrangement comprises a plug 7 of plastics material which is inserted into the open end 3 of the dispenser 2 after the barrel 1 has been charged with the product to be dispensed.
  • the plug 7 forms a tight fit within the barrel 1 and has a concave leading surface 7A.
  • the plug 7 has an axially extending peripheral skirt 9 having a slightly concave outer surface 11.
  • a central region of the outer surface 11 of the skirt 9 is provided with one or more (in this case three) radially projecting circular ribs 13.
  • the plug is formed with a central circular bleed aperture 15 surrounded by an axially extending annular wall 17.
  • the axial length of the wall 17 is approximately half that of the peripheral skirt 9-
  • a conical portion of the internal surface 19 of the wall 17 flares towards a free end of the wall 17 so as to interconnect the aperture 15 with a portion of the wall 17 having an internal diameter which is greater than the internal diameter of the aperture 15.
  • the free end of the wall 17 is formed with axial projections in the form of castellations 21 which are shown in phantom in Figures 1 and 2.

  • the castellations have approximately the same axial length as the wall 17.
  • a stopper plug generally indicated at 23 and shown in detail in Figure 5 is provided for sealing the aperture 15 of the plug 7.

  • the intermediate portion 27 terminates in an axially extending cylindrical stem portion 33 which has a smaller diameter than the intermediate portion 27 to which it is connected by a topped conical shoulder 31 intended to cooperate with the conically tapered portion of the internal surface 19 of the upstanding wall 17.
  • the stem portion 33 of the stopper 23 is formed at its free end with a conical head 35 defining with the stem a radially extending annular sealing surface 37 of greater external diameter than the diameter of the aperture 15.
  • the sealing surface 37 is intended to engage the underside of the plug 7 around the aperture 15 when the sealing plug 23 is in place as shown in Figure 2.

  • the concave outer surface 11 of the skirt 9 and annular ribs 13 provided thereon ensure that the plug 7 grips the internal wall of the barrel 1 in order to provide an effective seal between the plug 7 and the barrel.
  • the plug 7 is inserted further into the container until the adhesive within the bore 19 rises to the level of the flared portion of the bore.
  • the stopper 23 is then inserted into the bore as shown in Figure 1.
  • the adhesive which has risen in the bore is displaced by the head 35 of the stopper 23 and is forced to rise further between the bore 19 and the stopper 23. This causes the air above the adhesive in the bore 19 to be expelled from the bore between the casellations 21.
  • the head 35 of the stopper engages in the aperture 15 of the plug 7 and prevents further adhesive being drawn into the bore 19.
  • the main portion 25 of the sealing plug 23 moves into cooperation with the bore 19 as shown in Figure 2, thus effectively isolating the adhesive within the annular gap 39 from the reservoir within the container 1 and the free end of the container.
  • the radial sealing surface 37 of the head 35 snaps into engagement with the underside of the plug 7 around the aperture 15 and prevents the stopper 23 from being removed from the bore 19•
  • the plug 7 can then be advanced within the barrel 1 in order that the adhesive or resin in the reservoir in the container is delivered through a nozzle connected to the end of the barrel 1 remote from the free end thereof.
  • stopper 23 could be provided at the foot of a hand plunger wherein the upper portion 25 of a sealing plug 23 would be extended in order to form a handle upon which pressure would be exerted in order to advance the plug 7 within the container and force adhesive from the nozzle end of the container.
  • the wall 17 is extended to approximately the same axial length as the skirt 9.
  • the castellations 21 which allows air to escape from the bore 19 as the sealing plug 23 is inserted into the bore in the first embodiment, are replaced in this second embodiment by one or more channels 41 through the wall 17 such that air in the bore 19 may escape as the stopper 23 is inserted into the bore.
  • the apertures 41 are completely covered by the main portion 25 - 9 -
