Publication number: 20220142145Abstract: An actuation valve for a pest control device, the actuation valve including a primary valve seat; a secondary valve seat; a valve seal, a recess between the primary and secondary valve seats, and an actuation arm. The actuation valve includes primary and secondary valves. The recess is located between primary and secondary valve seats to receive gas from the primary valve and promote displacement of the valve seal from the secondary valve seat. Also provided are an actuation valve with magnetic elements, an actuation valve with a trigger, a pest control device, a piston assembly for a pest control device, and a pest control assembly.Type: ApplicationFiled: February 24, 2020Publication date: May 12, 2022Inventors: Craig Richard BOND, Robert Blair VAN DAM

Publication number: 20200396981Abstract: An animal trap includes: a bait, a support, and an elastic band, wherein in a set state the support supports the elastic band in an expanded state, and wherein removal, consumption or destruction of the bait by an animal: causes the elastic band to contract around the animal to kill the animal; or causes the elastic band to drive a kill mechanism to kill the animal. Animal traps may be formed substantially or entirely of biodegradable materials. Animal traps may be adapted for aerial distribution. A trap dispenser may dispense traps as they are triggered.Type: ApplicationFiled: September 8, 2020Publication date: December 24, 2020Applicant: GOODNATURE LIMITEDInventors: Craig Richard BOND, Robert Blair VAN DAM, Stuart William BARR

Publication number: 20170202206Abstract: An animal trap may include a source of compressed gas; a trigger mechanism configured to be actuated by an animal, and a kill mechanism powered by compressed gas. The trap may include two or more trigger valves connected in series. At least one trigger valve may include an opening, a valve seat surrounding the opening, a valve member having a sealing surface, and an O-ring arranged to seal between the sealing surface and the valve seat. One or more flow paths may allow gas to flow along at least part of an internal periphery of the O-ring. The trigger may include a trigger rod extending in a rest position from a mount at or near a first end thereof. The trigger rod may be mounted for pivoting movement about the mount, and may have two rotational degrees of freedom. Pivoting movement of the trigger rod in any direction away from the rest position may result in actuation of the trigger.Type: ApplicationFiled: April 5, 2017Publication date: July 20, 2017Applicant: Goodnature LimitedInventors: Craig Richard Bond, Stuart William Barr, Robert Blair van Dam

Patent number: 9468204Abstract: An animal trap is powered by compressed gas and includes a trigger mechanism and kill mechanism. The trap is preferably self-resetting. A variety of sources of compressed gas may be used, and different kill mechanisms may also be used. The trap is particularly suited to applications where low-maintenance traps are required, because it uses a simple, reliable mechanism which can kill a number of animals over a long period of time without requiring maintenance or manual resetting.Type: GrantFiled: March 3, 2010Date of Patent: October 18, 2016Assignee: Goodnature LimitedInventors: Craig Richard Bond, Robert Blair van Dam, Stuart William Barr
