Definitions

  • the present invention relates to an actuator cap for aerosol cans. More particularly, the invention relates to actuator cap for aerosol cans for the inflation of borehole plugs.
  • Inflatable borehole plugs usually comprise a sealed gas tight flexible bag containing a source of pressurized fluid which, when actuated has a time delay property to enable the flexible bag to be lowered into a borehole to a predetermined depth before expanding against the borehole wall to form a deck.
  • the source of pressurized fluid comprises an aerosol canister with a conventional valve stem and a mechanical actuator which, when actuated, holds the valve in an open position to discharge the entire contents of the canister in a manner similar to insecticide "bombs" or other aerosol fumigants.
  • actuator cap for controlling discharge of an aerosol canister is described in AU2007216888.
  • the arrangement disclosed therein relies upon the use of a valve control mechanism that includes a control member transversely positioned to the canister. This control member is transversely slidable relative to the canister so as to engage the discharge nozzle and effect discharge of the canisters contents.
  • the sliding control member however, has an inherent problem when subjected to extremes in environmental temperature commonly encountered on mine sites.
  • the pedestal of the valve may protrude as a result of the increased internal pressure of the canister and subsequently engage the underside of the sliding control member and thereby expelling the contents of the canister.
  • the ease with which a user actuates the slidable control member may be adversely affected such that it is more difficult to push in and activate the canister to discharge its contents.
  • an actuator cap for an aerosol canister comprising:
  • a base for engaging an end portion of the aerosol canister, the base further defining a longitudinal axis
  • control member hingedly mounted to the base at a pivot point; and a first locking element for retaining the control member in the activated position
  • control member is configured for internal pivotable movement relative to the base from a retracted position at which the control member is not engaged with the first locking element to an activated position at which the control member engages the first locking element.
  • control member comprises a base wall angularly attached to an outer wall so as to define an angled juncture therebetween, the angled juncture hingedly mounted to the base at the pivot point.
  • the actuator cap of the present aspect further comprises a second locking element for retaining the control member in a primed position adjacent the activated position, wherein the second locking element prevents or inhibits external pivotable movement of the control member while allowing for internal pivotable movement thereof to the activated position.
  • the second locking element comprises a pair of second locking elements disposed at spaced positions on the base and between which is disposed the first locking element.
  • first and/or second locking elements are positioned on the base opposite the control member.
  • first and/or second locking elements extend axially from a projection extending inwardly from the base.
  • the first and/or second locking elements include a hooked portion for engaging an end portion of the control member when in the respective activated and/or primed positions.
  • the end portion of the control member comprises a lip portion adapted to receive the hooked portion of the first and/or second locking elements.
  • control member further comprises a recessed portion positioned to engage a discharge nozzle of the aerosol canister when the control member is internally pivoted to the activated position.
  • the recessed portion is recessed from an outer surface of the base wall.
  • control member comprises an aperture configured to substantially overlie an outlet of the aerosol canister upon internal pivotable movement thereof to the activated position.
  • the actuator cap of the present aspect further comprises a skirt extending axially from the base, said skirt extending around a portion of the base so as to define a pair of free ends between which is disposed the control member and the pivot point.
  • the actuator cap is of a unitary structure.
  • the invention resides in an aerosol dispenser for inflation of a borehole plug comprising:
  • an aerosol canister including a discharge nozzle at an end portion thereof and having an outlet, wherein the discharge nozzle is biased to a closed position; and an actuator cap including:
  • a base engaged to the end portion of the aerosol canister and defining a longitudinal axis
  • control member is configured for internal pivotable movement relative to the base from a retracted position at which the control member is not engaged with the discharge nozzle to an activated position at which the control member engages the discharge nozzle to move said discharge nozzle to an open position and facilitate discharging of the aerosol canister.
  • the actuator cap is that of the first aspect.
  • the invention resides in a method of inflating a borehole plug, including the steps of:
  • a base for engaging an end portion of the aerosol canister, the end portion including a discharge nozzle having an outlet, wherein the discharge nozzle is biased to a closed position, the base further defining a longitudinal axis;
  • control member hingedly mounted to the base at a pivot point and configured for internal pivotable movement relative to the base from a retracted position at which the control member is not engaged with the discharge nozzle to an activated position at which the control member engages the discharge nozzle to move said discharge nozzle to an open position;

  • the actuator cap 100 includes a hollow or open ended cylindrical base 1 10 which is configured to be able to be rigidly and reversibly mounted to the upper rim of an aerosol canister.
  • the actuator cap 100 is of dimensions to be operably coupled to one or more of the various designs of aerosol canister known in the art that include a standard aerosol gas release valve disposed in the upper end wall or pedestal of the body of the canister.
  • the upper end wall of the canister typically includes a rim which surrounds the release valve for reversibly receiving and engaging the cylindrical base 1 10 of the actuator cap 100.
  • the actuator cap 100 further includes a triangular prism-shaped control member 120 comprising a base wall 121 having a first end 121 a and a second end 121 b and a planar outer wall 122 extending substantially perpendicularly from the first end 121 a of the base wall 121 so as to define a substantially right angled juncture 123 therebetween.
  • a triangular prism-shaped control member 120 comprising a base wall 121 having a first end 121 a and a second end 121 b and a planar outer wall 122 extending substantially perpendicularly from the first end 121 a of the base wall 121 so as to define a substantially right angled juncture 123 therebetween.
  • the right angled juncture 123 between the base wall 121 and the outer wall 122 is hingedly or pivotably connected to an outer edge portion of the cylindrical base 1 10 at a pivot point 130 so as to allow for pivotable movement of the control member 120 relative to the cylindrical base 1 10 between open, primed and activated positions, as shown in Figures 1 , 3 and 4 respectively.
  • the actuator cap 100 is preferably composed of a resiliently deformable material, including suitable plastic materials as are known in the art, like polypropylene, such that the control member 120 is resiliently biased towards the open position by the pivot point 130.
  • the control member 120 further includes a pair of opposed side walls 124a-b connecting outer edge portions of the base wall 121 and the outer wall 122 so as to define an opening therebetween.
  • the base wall 121 further includes a recessed portion 126 disposed therein.
  • the recessed portion 126 is recessed from an outer surface 121 c of the base wall 121 and positioned adjacent an end portion of the second end 121 b thereof so as to define a semicircular or triangular step or lip 127 at a portion of a free end 128 of the base wall 121 .
  • the recessed portion 126 includes a bottom portion 126a being substantially planar and having a through-hole or aperture 129 therein, which is configured to be aligned with or overlie the opening of a valve of an associated aerosol canister (not shown) upon movement of the control member 120 to the activated position.
  • the actuator cap 100 further includes an outer skirt 140 proximally or axially extending from a portion the cylindrical base 1 10.
  • the skirt 140 circumferentially extends around a substantial portion of the outer diameter of the cylindrical base 1 10 so as to define a pair of free ends 141 a-b thereof, between which is disposed the control member 120 and the pivot point 130.
  • respective end portions of the skirt 140 flare outwardly so to define a pair of opposed skirt wall portions, between which is defined a space to allow for uninterrupted pivotal movement of the control member 120 therein.
  • the skirt 140 is suitably of dimensions to inhibit or prevent accidental pivotal movement of the control member 120, such as during transport, from the open or primed position to the activated position.
  • the actuator cap 100 further comprises a semi-circular planar projection 150 extending radially inward from a portion of the base 1 10. Extending axially or upwardly from the upper surface of the projection 150 are a pair of first latch elements 160, 170, which are at spaced positions along an inner edge portion of the projection 150 and positioned opposite the control member 120. Each of the first latch elements 160, 170 includes a respective hook portion 161 , 171 at a distal end thereof adapted to slide over and engage a respective portion of the free end 128 of the base wall 121 when the control member 120 is internally pivoted to the primed position.
  • first latch elements 160, 170 act to retain the control member 120 in the primed position (i.e., prevent external pivotable movement of the control member 120 to the open position), but allow for further internal (i.e., inward and/or downward) pivotable movement of the control member 120 to the activated position.
  • each of the first latch elements 160, 170 include a first portion 162, 172 and a second portion 163, 173 said second portion 163, 173 angularly disposed relative to said first portion 162, 172 so as to allow for passage of the control member 120 from the primed to the activated position without further contacting the first latch elements 160, 170.
  • a second latch element 180 Disposed between the pair of first latch elements 160, 170 is a second latch element 180 extending axially or upwardly from the projection 150.
  • the second latch element 180 is shorter in height and wider in dimension than each of the first latch elements 160, 170, such that further internal pivotal movement imparted on the control member 120 results in the control member 120 disengaging from the first latch elements 160, 170 and the lip 127 subsequently contacting and sliding over a leading face of a hook portion 181 of the second latch element 180 and then underneath so as to abut a lower surface of the hook portion 181 and be engaged thereby and retained in the activated position.

  • other locking means or locking elements such as pawl elements, cam locks, locking rods or bars, that are configured to abut and/or engage the control member 120, may be used as alternatives or in addition to said latch elements 160, 170, 180 when retaining said control member 120 in the primed and/or activated positions.
  • the release valve of an aerosol canister generally includes a tubular nozzle open at its upper end and associated with a valve element disposed within the upper end wall of the canister which is operably coupled to a valve seat further provided therein.
  • the valve and nozzle are biased upwardly by a spring element within the canister such that the valve interacts with the valve seat to keep it in closed position and in so doing define a deactivated state.
  • the valve element When the nozzle is contacted and depressed by internal pivotable movement of the control member 120 against the action of the spring element, the valve element disengages from the valve seat, thereby allowing the contents of the aerosol canister, which comprises a pressurized or liquefied gas or similar, to pass through the open upper end of the nozzle. As noted earlier, release of the contents from the aerosol canister is further facilitated by the aperture 129, which is configured to overlie the opening of the nozzle when the control member 120 has been internally pivoted to the activated position.
  • the actuator cap 100 is attached to a suitable aerosol canister as required.
  • the control member 120 Prior to use, the control member 120 is preferably in the primed position so as to not only allow for easy actuation to the activated position, but also to inhibit or prevent accidental activation by virtue of the encompassing skirt 140.
  • the aerosol canister together with the actuator cap 100 may then be placed into a bag which is subsequently closed or sealed that would be understood to comprise the borehole plug.
  • the control member 120 of the actuator cap 100 Prior to lowering the borehole plug into a borehole, the control member 120 of the actuator cap 100 is manipulated through the flexible sides of the still deflated borehole plug by a user to pivotably move the control member 120 from the primed position to the activated position.
  • the borehole plug is then inserted into the borehole to fall freely with the second latch element 180 ensuring that the control member 120 is retained in the activated position and by extension the discharge nozzle remains depressed thereby so that discharge from the aerosol canister continues until it is exhausted.
  • One particular advantage of the above described embodiment is that it allows for single-handed activation of the actuator cap 100 and subsequent discharge of the aerosol canister.
  • a further advantage of the present embodiment is that if the valve stem of the canister to which the actuator cap 100 is engaged rises under hot conditions or lowers under cold conditions, there is typically sufficient flexibility in the position of the control member 120 when in the primed position to allow for this up and down movement of the valve stem with such temperature changes without activating the aerosol canister to discharge its contents.
