Time-delay actuator assembly for an aerosol container

摘要

A time-delay actuator assembly is disclosed that can dispense chemicals from an aerosol container. The time-delay actuator assembly is mountable to the aerosol container and includes an inner cap, an outer cap adjacent the inner cap, a retainer coupled to the outer cap, a biasing member, and a time-delay member that resists essentially axial relative movement between the inner cap and the outer cap when the outer cap has been rotated to align a guide member with an essentially axial section of a guide track, thereby causing a time delay between when the guide member is aligned with the essentially axial section and when chemicals are dispensed from the aerosol container.

1. A time-delay actuator assembly suitable for dispensing a chemical to ambient environment from an aerosol container having a release valve, comprising:
an inner cap defining an opening and adapted to mount on the aerosol container; an outer cap adjacent the inner cap; a retainer coupled to the outer cap and extending through the opening in the inner cap; an actuator extending from at least one of the outer cap and the retainer, and adapted to selectively engage the release valve; a biasing member urging the actuator toward the release valve; a time-delay member resisting essentially axial relative movement between the inner cap and the outer cap; a guide track formed on one of the inner cap and the outer cap, and having a circumferential section and an essentially axial section; and a guide member formed on the other one of the inner cap and the outer cap adapted to engage the guide track; wherein rotating the outer cap relative to the inner cap moves the guide member along the circumferential section of the guide track; and wherein when the guide member is aligned with the essentially axial section of the guide track, the biasing member urges the actuator toward the release valve in a manner such that resistance of the time-delay member to essentially axial movement between the inner cap and the outer cap causes a time delay between when the guide member is first aligned with the axial section and when the actuator engages the release valve.
