  • the absorbent paper absorbs the attractant composition, but does not readily yield the absorbed liquid on pressure. This is to be distinguished from a sponge or sponge-like matrix as is used in some prior art devices. These sponges yielded liquid absorbed when they are compressed.
  • the device 10 is more cost-effective than the prior art devices. It will be appreciated that any suitable dry absorbent material can be used instead of absorbent paper.
  • the attractant carrier 16 can thus, for instance, be provided by a gel or water retention matrix such as is used in baby diapers or for soil improvement.
  • the housing 12 can be of less sturdy construction than that of the prior art devices where a relatively heavy sponge has to be held in the housing 12.
  • the absorbent paper attractant carrier 16 does not leak during transportation, even when exposed to air pressure differences typically experienced during air travel.

  • the tablet well 76 is thus a shallow cavity adjacent to the upper end of the tube 66 for holding a gas release tablet 26.
  • An upper rim of the body 66 is provided with a circumferentially extending series of axially projecting pins or spacers 78 serving to space the rim from an inside of the housing 12 to ensure exposure of the tablet 26 to air in the trap chamber 14.
  • a radially outwardly directed cylindrical wall of the body member 66 provides the holding formation for holding the attractant carrier 16.
  • the sheet of absorbent paper 16 thus extends circumferentially about the body member, in use, girding the carrier unit 64, and a circumferentially extending ridge or lip 72 which projects radially outwardly from the lower end of the body member 66.
  • the lip 72 anchors the sheet 16 against slipping downwardly from the carrier unit 64 under gravity.
  • the radially outer surface of the body member 66 can be provided with axially extending ribs, to increase the exposed surface area of the attractant carrier 16.
  • the carrier unit further has a number of mounting formations for mounting the body member 66 in the trap chamber 14 such that it is selectively removable and replaceable.
  • the mounting formations are in the form of three resiliently deformable limbs 68 which projects radially outwardly from the body member 66 at the lower end of the body member 66.
  • the limbs 68 are downwardly inclined relative to the lengthwise direction of the body member 66.
  • the limbs 68 are inherently resilient, being made from a suitable plastics material.
  • the housing 12 is in the form of a bell shaped cowl 58 of transparent plastics material.
  • the cowl 58 has a circular cross-section of varying diameter, forming a constriction 62 adjacent to the entrance 24 to the trap chamber.
  • the constriction 62 is of a diameter which is smaller than that of the free ends of the limbs 68 relative to the longitudinal axis 71 of the carrier unit 64.
  • the carrier unit 64 is inserted into the cowl 58 through the entrance 24, the tablet well 76 leading. During such insertion, the limbs 68 bear against the inside of the cowl 58 at the constriction 62. If sufficient force is applied to the carrier unit 64 in an axial direction, the limbs 68 are deformed to retract radially inwardly, permitting passage of the carrier unit 64 into the trap chamber 14. Once the limbs 68 have passed through the constriction 62, they expand radially outwardly due to their inherent resilience, so that the carrier unit 64 effectively dilates to be held captive in the trap chamber 14. The orientation of the limbs 68 are such that the carrier unit 64 cannot be withdrawn from the cowl 58 simply by gripping and pulling the body member 66 towards the mouth 24. The limbs 68 also serve to centre the carrier unit 64 in the housing 12.

  • each limb 68 has a barb or spur 73 which faces operatively upwardly for hooking cooperation was one of the prongs 86.
  • the prongs 86 of the tool 80 is inserted into the trap chamber 14, so that each hook 88 engages one of the limbs 68.
  • a user then pulls downwardly forcibly, which results in radially inward contraction of the limbs 68 due to the orientation of the prongs 86.
  • the limbs 68 are thus anchored to the tool 80 by engagement of the prongs with the respective spurs 73.
  • the device 70 of Figure 6 it facilitates maintenance of the device 70, as the gas tablet 26 and the carrier 16 can be replaced on the carrier unit 64 when it is separated from the cowl 58. Furthermore, the carrier unit 64, and thus the gas tablet 26 and the attractant carrier 16 are securely located in the trap chamber 14. Not only is it highly unlikely that the carrier unit 64 will fall out of the cowl 58 accidentally, but the construction of the limbs 68, frustrates unauthorised removal of the carrier unit 64, for instance by children, without the necessary tool 80.
  • gas action tablets 26 will typically be distributed separately in a hermetically sealed sachet for point of use insertion.
