Definitions

  • Embodiments of the invention relate to systems and methods for introducing chemical agents into aerosol containers.
  • Liquefied-gas aerosol dusters provide a safe, useful, convenient, and economically efficient means of cleaning dust and debris from hard to reach places, where it can be harmful or detrimental. This can be especially true for the multitude of electronic equipment used today, where small foreign particles can render expensive equipment inoperable or shorten its useful life.
  • These aerosol dusters provide an easily available source of pressurized gas that can be used to remove such debris.
  • the liquefied gas and aerosol package components can be chosen so as to deliver a pressurized burst of gas in a preferred cleaning pattern.
  • the aerosol valve and actuator can be configured to deliver the appropriate amount of gas at the right pressure in a range from broad to pinpoint spray patterns. Using liquefied gases provides an ample supply of material for a large number of cleaning tasks in a compact package.
  • duster products provide a safe and valuable function to the consumer, but sometimes are involved in inhalation abuse incidents, like numerous other consumer products.
  • bittering additive agent also referred to herein as a bittering agent, or bitterant
  • a bittering additive agent also referred to herein as a bittering agent, or bitterant
  • a dosing module, valve module and crimping module are all included on a single, automated apparatus. Because of this orientation, the time from when the bittering agent is added to the container, until a valve is placed on the container and subsequently crimped, is relatively short. For this reason, there is relatively little time when the bittering agent is exposed to the ambient environment.
  • the bittering agent by its nature, has a unsavory aroma and/or taste, and minimizing such exposure reduces the unwanted introduction of bittering agent to facility workers and the general facility environment.
  • embodiments of the invention provide for an efficient system and method for adding a bittering agent to aerosol containers.
  • Embodiments can include a method for introducing a bittering agent into an aerosol container.
  • the method can include the steps of: adding a dose of the bittering agent in the container, positioning a valve on the container, crimping the valve to the container, and adding an aerosol propellant to the container.
  • the method can further include the step of adding an actuator to the container.
  • the method can further include the step of testing the container in a bath.
  • the steps of adding a dose of the bittering agent in the container, positioning a valve on the container and crimping the valve onto the container can be performed by an automated device.
  • the time interval between adding a dose of the bittering agent in the container and positioning a valve on the container can be in the range of about 1 to 5 seconds.
  • a distance that the container travels between the steps of adding a dose of the bittering agent in the container and positioning a valve on the container can be in the range of about 2 to 16 inches.
  • Embodiments can include an apparatus for introducing a bittering agent into an aerosol container.
  • the apparatus can include a turntable for positioning the container, a dosing module for adding a dose of the bittering agent in the container when the turntable positions the container proximate the dosing module, a valve module for positioning a valve on the container when the turntable positions the container proximate the valve module, and a crimping module for crimping the valve to the container when the turntable positions the container proximate the valve module.
  • the time interval between when the container is positioned proximate the dosing module and when the container is positioned proximate the valve module can be in the range of about 1 to 5 seconds.
  • a distance between where the container is positioned proximate the dosing module and where the container is positioned proximate the valve module can be in the range of about 2 to 16 inches.
  • FIG. 1 is a flow diagram illustrating certain embodiments of a method of adding a bittering agent to a container
  • FIG. 2 is a schematic diagram illustrating a system for implementing the method shown in FIG. 1 ;
  • FIG. 3 is a schematic diagram illustrating a portion of system for implementing the method shown in FIG. 1 ;
  • FIG. 4 is a more detailed view of the portion of the system shown in FIG. 3 ;
  • FIG. 5 is a schematic diagram illustrating a portion of system for implementing the method shown in FIG. 1 .
  • Embodiments of the invention relate to a system and method for introducing a chemical agent into a container.
  • a method for adding a bittering agent to an aerosol container can include depositing a dose of bittering agent into a container (step S 10 ), adding a valve to the container (step S 12 ), and crimping the valve to the container (step S 14 ).
  • a dose module 220 can be used to add a dose of a bittering agent into a container 210 .
  • a valve module 230 can position a valve on the container 210 .
  • a crimp module 240 can crimp the valve to the container 210 .
  • a propellant module 250 can be used to add propellant to the container 210 .
  • the container 210 can be tested in a bath module 260 .
  • an actuator can be placed on the container 210 by the actuator module 270 .
  • Dose module 220 can include a dispenser and a syringe 222 , coupled by an air line.
  • the dispenser 224 causes a bitterent placed in the syringe 222 to be added to the container 210 in a relatively precisely determined amount.
  • dispenser 224 can be triggered, via, for example, switches, to initiate the addition of the dose of bitterent when container 210 is in a predetermined position.
  • position sensor mechanism 226 can include a combination of one or more limit switches, spring return cylinder switches, and track switches.
  • portions of the position sensor mechanism 226 , as well as the dispenser 224 can operate with the use of air system.
  • dose module 224 can include two dispensers 224 , two syringes 222 and two position sensor mechanisms 226 such that two containers can be dosed with bitterent simultaneously, or substantially simultaneously.
  • FIG. 5 there is shown a top partial schematic view of an embodiment of a system as described above.
  • Containers 221 are positioned on turntable module 300 .
  • Dispensers 224 initiate the dosing of bitterent from syringes 222 .
  • the turntable then indexes the containers 221 to the valve placer module 230 , where a valve is positioned on each of containers 221 .
  • the turntable module 300 indexes the containers to a position proximate the crimper module 240 .
  • the valves can be crimped to the containers 221 .
  • the syringe 222 of dosing module 220 , valve placer module 230 and crimper module 240 are all included on a single, automated apparatus. Because of this orientation, the time from when the bittering agent is added to the container 221 , until a valve is placed on the container and subsequently crimped, is relatively short. For this reason, there is relatively little time when the bittering agent is exposed to the ambient environment.
  • the bittering agent by its nature, has an unsavory aroma and/or taste, and minimizing such exposure reduces the unwanted introduction of bittering agent to facility workers and the general facility environment.
  • time T 1 (the time from when the container 221 is at the dosing module 220 to when the container is at the valve placer module 230 ) can preferably be in the range of 1 to 5 seconds, more preferably in the range of 1 to 3 seconds, and most preferably, about 2.5 seconds.
