  • certain embodiments of the present invention may prevent different and potentially incorrect product containers being erroneously or maliciously used with a particular type of actuator.
  • Certain embodiments of the present invention may provide an aerosol can or other dispensing device that includes an actuator/nozzle component which is securely attached to the valve assembly of the device to prevent the same being accidentally knocked off the device during transit, storage, use, or the like and eliminates the risk of children or pets swallowing a relatively small actuator/nozzle component which could otherwise be fatal.
  • the stem and/or actuator may snap and fail irrevocably rendering the aerosol device useless and thus preventing a different actuator being used with the device or the product container, e.g. can, of the device being used with the same or another actuator.
  • the stem will also be damaged preventing its reuse and/or product contained in the device being removed, refilled or tampered with.
  • the stem of a valve assembly according to certain embodiments of the present invention may include one or more frangible regions to allow the stem to fail or fracture when a predetermined force is applied to the actuator and/or stem.
  • Such a frangible region may include one or more fine annular recesses, regions of reduced thickness, die- cuts or the like in the wall of the stem which does not compromise the integrity of the stem during normal use and allows a substantially axial force to be applied to the stem via the actuator without failing when product is to be dispensed from the aerosol device, whilst allowing the stem to at least partially fracture when a predetermined shear force is applied to the stem and/or actuator during abnormal use.
  • the one or more recesses in the stem may provide a frangible portion to allow the stem to fracture when an excessive shear force is applied to the actuator or stem.
