Total Claims: 15
Claim 1
Independent Claim
160 words
IN AN ANIMAL COLLAR HAVING A BUCKLE ATTACHED THERETO, OPTIONALLY PUNCHED WITH HOLES FOR THE CONTROL FLEAS AND TICKS ON CATS AND DOGS, THE IMPROVEMENT CONSISTING OF A SOLID PESTICIDAL COMPOSITION IN THE FORM OF AN ELONGATED BAND SUITABLE FOR FORMING SAID ANIMALS FOR THE CONTROL FO FLEAS AND TICKS ON CATS AND DOGS, WHICH CONSISTS ESSENTIALLY OF 5 TO 15 PERCENT OF A CARBAMATE SELECTED FROM 1-NAPHTHYL N-METHYL CARBAMATS AND 2-ISOPROPOXYPHENYL N-METHYL CARBAMATE; 40 TO 70 PERCENT OF A SOLID THERMOPLASTIC VINYLIC RESIN; AND FROM 10 TO 50 PERCENT PLASTICIZER SELECTED FROM THE PHTHALIC ESTERS, ADIPIC ESTERS AND PHOSPHORIC ESTERS, SAID PERCENTAGE BY WEIGHT OF THE TOTAL COMPOSITION SAID COMPOSITION CHARACTERIZED BY BEING ESSENTIALLY DRY AND THE PROPERTY OF PROVIDING A SELFREPLENISHING COATING OF PARTICLES OF THE CARBAMATE ON THE SURFACE OF THE COMPOSITION BY MIGRATION OF THE CABAMATE FROM THE BODY OF THE COMPOSITION, SAID MIGRATION OCCURING WHENEVER CARBAMATE PARTICLES ARE DISPLACED FROM THE SURFACE OF THE CMPOSITION.

Claim 3
Dependent Claim
46 words
The improvement according to claim 1 wherein the vinyl resin is a homopolymer of vinyl chloride or a copolymer of vinyl chloride and the plasticizer is selected from phthalic esters and adipic esters, said plasticizer being present in the amount of from 25 to 50 percent.
Claim 4
Dependent Claim
13 words
The improvement according to claim 2 wherein the carbamate is 1-naphthyl N-methyl carbamate.
Claim 5
Dependent Claim
13 words
The improvement according to claim 2 wherein the carbamate is 2-isopropoxyphenyl N-methyl carbamate.
Claim 6
Dependent Claim
12 words
The improvement according to claim 3 wherein the resin is polyvinyl chloride.
Claim 7
Dependent Claim
12 words
The improvement according to claim 4 wherein the resin is polyvinyl chloride.
Claim 8
Dependent Claim
146 words
In a method for the control of fleas and ticks on cats and dogs by the step of providing a buckled collar around the neck of the cat or dog formed of a solid pesticidal composition, the improvement wherein said composition consists essentially of 5 to 15 percent of a carbamate selected from 1-naphthyl N-methyl carbamate and 2-isopropoxyphenyl N-methyl carbamate; 40 to 70 percent of a solid thermoplastic vinylic resin; and from 10 to 50 percent plasticizer selected from the phthalic esters, adipic esters and phosphoris esters, said percentages, by weight of the total composition, said composition characterized by being essentially dry and the property of providing a self-replenishing coating of particles of the carbamate on the surface of the composition by migration of the carbamate from the body of the composition, said migration occuring whenever carbamate particles are displaced from the surface of the composition.
Claim 9
Dependent Claim
146 words
