Description

(54) IMPROVED DE-LOUSING CONTAINER AND METHOD (71) I, Louis LESLIE PHILLIPS, British subject of 206, Bridgewater Road, Wembley, Middlesex, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to performed, to be particularly described and and by the following statement: This invention relates to a method of de-lousing an animal, particularly a domestic cat or dog, and to a container for use in carrying out the method.

According to the invention, the animal is placed within a container having a mouth through which protrudes the head of the animal, or at least the mouth and nose portion thereof; the mouth of the container is secured about the animal, and the portion of the body of the animal within the container is subjected to the effect of a delousing agent contained within the container.

Preferably, the de-lousing agent is a pesticide in solid or liquid form contained within a pocket or other enclosure within the container. The pesticidal material should form a vapour within the container and the material sold under the trade mark "Vapona" is an example of a material which has been found to be especially efficacious.

The invention also provides a container for carrying out the de-lousing method referred to above, said container being in the form of a bag having a mouth which is provided with means for securing it around the neck portion of an animal to be treated, and a pocket or other receptacle within the bag for retaining the de-lousing agent. The mouth of the bag may, for example, be provided with draw strings, press-studs, a tongue and groove closure or any convenient form of sliding clasp fastener to enable it to be sealed about the neck of the animal. Preferably the container comprises a relatively rigid base (e.g. of wood, cardboard or fibre glass) and a flexible side wall. The material forming the flexible side wall or bag may be of any suitable material which restricts escape of the vapour of the pesticide and which is capable of withstanding the struggles of an animal. Examples of materials from which the bag or flexible wall of the container may be constructed include, fabrics, eg. canvas (which may be proofed or unproofed), and plastics materials, e.g. P.V.C. which may be reinforced with nylon or other fibrous material.

The invention will now be described in greater detail but by way of example only with reference to the accompanying draw ing, - which shows a partially cut-away view of a container embodying the invention and into which an animal has been placed for treatment.

As shown in the drawing; the container has a cardboard base 1 sealed to a side or peripheral wall 2 of polyvinylchloride reinforced with nylon mesh or other fibre.

At the upper end of the wall 2 is a mouth 3. Draw strings 4 enable the mouth of the bag to be drawn sufficiently tightly about the neck of the animal to be de-loused to prevent the escape of fumes from the delousing agent.

The de-lousing agent consists of a block of solid pesticide contained in a pocket 5 in the inside wall of the bag. The pocket has perforations 6 to allow vapour or fumes to escape from the pocket and pervade the interior of the bag, thereby destroying insect or other pests contained on the fur or skin of the animal. A device may be provided to prevent the escape of fumes when the container is not in use.

The pesticide is preferably the insecticide sold under the trade mark "Vapona", which is described more particularly in United States patent No. 2956073 and con sists of the dimethyl ester of 2,2-dichlorovinyl phosphoric acid. The pesticide is normally formulated in solid or liquid form with an inert carrier or diluent. Other pesticidal formulations, in solid or liquid form, including granules or powders may be used instead of the specific material referred to above.

Other arrangements for securing the mouth of the bag may be employed, and the de-lousing agent be containein some other form of receptacle either attached to or separate from the bag.

It will be appreciated that a particular advantage of the present invention is that solid or liquid pesticide does not directly contact the fur or skin of the animal. Instead the animal is maintained for a relatively short period, (usually about 20 minutes is sufficient) in an atmosphere containing vapor of the insecticide. As a result the animal is effectively de-loused in one or more treatments without causing skin rashes or sores by direct contact with the insecticide.

WHAT I CLAIM IS: - 1. A method of de-lousing an animal wherein the animal is placed within a container having a mouth through which protrudes the head of the animal or at least the mouth and nose portion of the animal, the mouth of the container is secured about the animal, and the portion of the body of the animal within the container is subjected to the effect of de-lousing agent contained within the container.

2. A method as claimed in Claim 1, wherein the de-lousing agent is the dimethyl ester of 2,2-dichlorovinyl phosphoric acid.

3. A method as claimed in Claim 1 or Claim 2, wherein the de-lousing agent is in solid form contained within a receptacle within the container.

4. A container for use in de-lousing an animal, said container being in the form of a bag having a mouth adapted to be secured around the neck portion of an animal to be treated and a pocket or other receptacle within the bag, said pocket containing a de-lousing agent, fumes from which pervade the interior of the bag.

5. A method of de-lousing an animal as claimed in Claim 1 and substantially as hereinbefore described.

6. A container for use in de-lousing an animal substantially as hereinbefore described with reference to and as illustrated in the accompanying drawing.
