Definitions

  • the invention relates generally to the structure and use of applicators for substances, such as pesticides, more particularly to applicators using external cartridges and still more particularly to applicators having trigger activated pumps.
  • Pesticides, insecticides, fungicides, and other chemical are often applied to specific smaller targets as well as large fields.
  • hand-held applicators can be used to bring the product close to the target and apply a quantity of chemical product to the target.
  • Products in the form of a gel may be applied in this way using cartridges containing the product that are attached to the applicators.
  • Prior applicators often have disadvantages such as not being designed to avoid under- or over- application of pesticide, not delivering a controlled amount of substance, and/or difficulty in applying the correct amount of substance, resulting in product waste, increased product cost, or over use.
  • Gardos discloses an applicator using a powered motor to operate a push rod to push product out of the cartridge.
  • the cartridge is mounted on the front side of the applicator.
  • a trigger turns on the pump which pushes the rod into the product cartridge thus pushing out the product.
  • Gardos does not allow for a measured application of a product because the product is emitted from the applicator as long as the trigger is held.
  • the cartridge is held by a complex holding mechanism that must be disassembled and reassembled when an empty cartridge is replaced. Additionally, because the push rod is motorized, the applicator is likely to be expensive to assemble and purchase.
  • U.S. Patent No. 7,451,900 to Hornsby, et al. (“Hornsby”) discloses an electrically powered pump delivery system in which a gear pump is used to eject liquid substances, e.g. insecticide or cleaner, onto a target.
  • the gear pump and electric power source such as a battery, are enclosed within a gun shaped housing.
  • Hornsby does not provide for the delivery of a consistent quantity of liquid onto a target as the trigger may be held and the pump operated for varying lengths of time.
  • the Hornsby delivery system is not particularly useful when a consistent quantity of product is required to be delivered onto a target.
  • the electrical power system and the complex gear pump tend to make manufacture and assembly of the disclosed delivery system comparatively more expensive than similar devices that are purely mechanically driven.
  • U.S. Patent No. 9,623,427 to Gilpatrick, et al. discloses a chemical injector for a spray device.
  • the device is attached to a water hose and includes a container for the chemical to be injected.
  • the trigger controls the delivery of water which mixes with the chemical and ejects a combined water-chemical solution.
  • This device has the disadvantage of being tied to the water hose and also requires both manipulation of the trigger for the water and a separate control for the chemical container.
  • Barton discloses a fluid delivery system.
  • the Barton device is gun-shaped but lacks a typical trigger. It is activated by pressing two recessed plates that activate a circuit to power the system.
  • the device is connected to an electric line that is connected to a control system.
  • the Gilpatrick device the Barton device is limited in range as it is connected to an electric line that is ultimately connected to a work station. Similar to Gardos and Hornsby, Barton does not provide for the delivery of a consistent quantity of liquid onto a target as the recessed plates may be held and the pump operated for varying lengths of time. Thus, the Barton delivery system is not particularly useful when a consistent quantity of product must be delivered onto a target.
  • an applicator assembly for a gel product includes: a housing having a first end and a second end; a pump enclosed by the housing; a handle extending from the housing; a cartridge receiving orifice proximate the first end of the housing; an outlet formed at the second end of the housing; a trigger assembly housed in the handle and operatively attached to the pump.
  • the applicator assembly includes an aiming light which may be an LED.
  • a cartridge having a distal end and a proximal end containing the gel-based product is releasably attached to the first end of the applicator.
  • Also disclosed is a method of using the applicator including: inserting a cartridge into the cartridge receiving port of the housing; pulling the trigger of the trigger assembly to actuate the pump; drawing the product from the cartridge; and, pumping the product through the outlet.
  • the cartridge may be prefilled with a product which can be a gel or liquid.
  • a method of applying a product onto a target including: releasably attaching the cartridge onto the applicator; pointing the outlet of the applicator toward a target; pulling the trigger of the trigger assembly of the applicator; and, pumping the product through the outlet of the applicator onto the target.
  • the cartridge is prefilled with the product.
  • the product may be an insecticide, pesticide, fungicide, herbicide, or any combination thereof.
  • the target may be a specific location or may be an undesired organism such as weeds, insects, fungi, spiders and other living plants or animals.

Trigger assembly 110 is returned by expansion of trigger return spring 111. Alternatively, trigger assembly 110 can be directly attached to pump plunger 203 to form the operative attachment ⁇ In each pump cycle, pump plunger 203 is moved from its resting position the same distance toward cartridge 120 ensuring the same quantity of product is drawn from cartridge 120.

  • the vacuum is created, the desired effect is to have the vacuum filled by drawing product from cartridge chamber 124 into inlet 212. However, as product is removed it will collapse in the chamber, i.e., it will fall away from the walls of chamber 124 and away from inlet 212 preventing product from reaching pump 200.

  • an external cartridge with applicator 100 has advantages in that it is easy to replace an empty cartridge with a full one.
  • a distinct advantage of this easily interchanged cartridge is that the applicator can readily be switched between products, either between different types of applications or within the type of application.
  • the ability to easily switch products is a feature of importance in integrated resistance management programs.
  • Other advantages include that applicator 100 is easier to use than other applicators in the field, as it is not tethered to a power or product line, and a known quantity of product is ejected with each pump cycle, which reduces overuse of the product.
  • Applicator 100 can be easily manufactured with different pump travel distances resulting in different embodiments delivering different quantities of product while operating with the same mechanism.
  • Different products may be used with the same applicator 100 including using a cartridge filled with a neutral cleaning solution to clean pump 200 and its component parts.
  • cartridge 120 By using cartridge 120 with a movable piston 126 moving toward inlet 212, cartridge 120 may be removed with a cap placed over cartridge outlet 130 with the integrity of the gel-like product maintained by the smaller chamber created by the movement of movable piston 126.
  • the structure of applicator 100 also enables a specific quantity of product to be ejected as pump 200 moves a specific distance and therefore draws a specific quantity of product from cartridge 120 on each pump cycle.
  • Applicator 100 can be used to apply the product contained in cartridge 120 to a target by inserting cartridge 120 into cartridge receiving port 214 housing and then pulling trigger assembly 110 to actuate pump 200. Activation of pump 200 will draw the product from cartridge 120 and pumping the product through outlet channel 206.
  • applicator 100 will include LED 107 which can be used to more easily aim applicator 100 toward a target.
  • the gel product may be an insecticide, a pesticide, a fungicide, a weed killer, or any combination thereof. Possible targets include, but are not limited to, insects, worms, weeds, fungi, spiders, or any combination of these and other suitable targets.
  • Products that may be used in applicator 100 include, but are not limited to, gel bait formulations used in control of cockroaches, ants, flies and other insect pests. However, applicator 100 is designed so any and all gel formulations can be used. Cartridges 120 may range in size from about 30 to about 36 gm (30 to 35 cc) cartridges, however larger cartridges 120 containing more product may be used, as cartridges 120 can be lengthened and/or widened to contain more product.
