Abstract

A device for despensing liquid pesticide which comprises a reservoir of liquid pesticide which can be attached to an animal, a fibrous wick having a diameter of less than three millimetres communicating with the liquid in the reservoir, said wick extending outwardly and sealably from the reservoir, whereby liquid can be passed out of the reservoir only along the wick, and venting means in the reservoir to prevent negative pressure developing inside the reservoir, venting is provided by having both ends of the wick passing out of the reservior and being exposed to the atmosphere.

Description

DEVICE FOR CONTROLLING ECTOPARASITES
This invention relates to a device to be attached to animals for the control of insects,acarids and other ectoparasites.
In US Patent 3,925,835 a device is disclosed for repelling face-flies from an animal's face in which liquid insecticide is dispensed from a container attached to the animal's ear via a wick. The wick shown in this patent is very large and flat and causes liquid to be depleted very rapidly. In US Patent
4,023,532, the inventor has attempted to overcome this problem by having a knot in the wick in the reservoir to restrict the flow of liquid. However, the devices disclosed in this patent are not practical and still show a relatively thick wick which will not give a controllable and sufficiently low rate of flow of liquid.
To achieve a sufficiently low rate of flow a very fine wick is required, i.e. comprising a fibre having a diameter of less them mm. The release rate can be regulated by the diameter and length of the exposed wick. However, the use of such a fine wick results in negative pressure building up inside the reservoir of liquid as liquid moves along the wick and after a short time little or no more liquid will pass along the wick.
Thus according to the invention, there is provided a device for dispensing liquid pesticide which comprises a reservoir of liquid pesticide, the said reservoir being in the form of a bulbous sachet, a fibrous wick extending completely through said reservoir in communication with said liquid pesticide and extending through the wall of said sachet, said wick having a first end and a second end remote from said first end, said first end extending sealably outwardly beyond said sachet wall to comprise a means for applying the pesticide to an animal by means of a wicking action, said second end being exposed to the atmosphere through wicking action, said second end being exposed to the atmosphere through said sachet wall to prevent a negative pressure developing inside said reservour, said wick being a diameter of less than three millimetres, and wherein said second end of said wick is at the top of said sachet in communication with the portion of
BAD ORIGINAL
-2said reservoir which contains no liquid pesticide as said liquid pesticide is being despensed from a location remote from said second end of said wick.
Alternatively, the reservoir can be provided with valve means to provide a vent. Another arrangement is to have a small piece of fibrous material, which allows passage of air but not liquid, to be positioned in the outer section of the reservoir.
To prevent soiling of the wick, it is preferably made of a synthetic material, e.g., polytetrafluoroethylene. Another suitable fibre is glass. Natural fibres such as cotton may also be suitable. The reservoir is preferably retained on the animal's body by means of an ear tag to which the reservoir can be attached. If desired, the reservoir can be an integral part of the tag or alternatively be separable and a new reservoir attached to the tag when the previous one is depleted.
It may be desirable for the reservoir to be divided into two or more sections, each with its own wick so that two or more chemicals may be dispensed separately.
The invention is illustrated with reference to the accompanying drawings in which:
Figure 1 shows a reservoir according to the invention;
Figure 2 shows a tag for holding the reservoir of Figure 1; Figure 3 is a section view of the reservoir held in position in the tag; and
Figures 4 and 5 are alternative embodiments of tag for holding a reservoir.
Referring to the drawings, the reservoir consists of a thin sachet usually of clear plastic material having a bulbous or thicker portion 2 for containing the major amount of an insecticide in luquid form. Wick 3 passes through the luquid and through heat sealed sections 4 and 5. A lower section of the sachet 6 can be cut away to expose the wick when the device is to be used. An alternative arrangement is to have the wick covered by an adhesive strip of material which can be removed to expose the wick. The other end of the wick does <

-3not protrude beyond its top of sachet but its end is exposed to the atmosphere to provide a vent. Liquid can thus pass out of the reservoir slowly along the lower part of the wick.
Although the wick is shown extending beyond the heat seal section 5, in an alternative arrangement this end of the wick can terminate at the edge of the reservoir, as shown for the upper end of the wick. This arrangement still allows insecticide to be dispensed from the reservoir. The wick is very thin, being
Less than 1 mm in diameter.
In Fugure 2 a tag 9 has a conventional opening 10 in the upper part to allow it to be attached to a cow's ear. The tag consists of two parts 22 and 12 which can be folded together along line 13 and held together by means of studs 14 which clip into holes 15. A section 16 is cut away to allow the lower section 6 of the sachet to pass through and hence enable the lower end of wick 3 to be exposed. Part 12 of the tag has a cut away portion 17 to receive the bulbous section 2 of the sache
Fugure 3 shows the schet in position with tag folded together. When the sachet is empty the tag can be opened and the halves of the tag can be separated and the old sachet replaced by a new one.
In an alternative arrangement the reservoir is integral with the tag, e.g. by heat sealing the two portions 11 and 12 together. If desired, the back of the reservoir can be integral with the tag portion 11.
Although the drawings show the wick exposed at the bottom of the tag, the wick can be exposed at another part of the tag, e.g. at the sides or the top.
In a further arrangement shown in Fugures 4 and 5, the tag consists of a back part 21 and a front part 22. The two parts can be folded along line 23 to give the configuration shown in figure 5. The two parts are held together by studs 24 which clip into holes 25. The front part 22 has a bulbous portion 26 to receive the bulbous section of the sachet of ...
BAD ORIGINAL A . . ./4
-4Figure 1. The bulbous portion has sections 27 cut out to enable the contents of the sachet to be seen. The ribs 28, which remain, give protection to the sachet. A section extends beyond the front part of the tag and has a hole to enable the tag to be attached to an animal's ear, e.g., by means of a conventional stud.
The tags may be made of any suitable material, usually a plastic, such as polyethylens.
The device of the invention can be used for treating ectoparasitic infection on animals, e.g., cats, dogs, pigs, sheep, goats and especially cattle. The infections which can be controlled depend on the nature of the chemical agent. Suitable agents include one or more of the following: amitraz; chlordimeform; carbamates, such as bendiocarb, propoxur and carbaryl; organophosphates, such as naled, dioxathion, phosmet, diazinon and dichlorvos; and pyrethroids such as permethrin, cypermethrin, fenvalerate, deltamethrin, cyhalothrin, flumethrin, and cyfluthrin.-----------—..... ._
