Abstract

Abstract An applicator for impressing brands or medicaments on animals has a handle mounted for movement towards or from an applicator pad containing a liquid chamber communicating with a base, a part of which, having the configuration of the area over which liquid is to be applied to an animal, is liquid-permeable. A liquid container, which may serve as the handle, leads to the liquid chamber by way of a valve mechanism such that each movement of the handle towards the applicator pad as the pad base is pressed on an animal introduces to the liquid chamber liquid under pressure which is expelled through the liquid-permeable part of the applicator pad base.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 229 words
An applicator for impressing liquid brands or medicaments on animals including: an applicator pad having a liquid permeable base free of any needles for surface application to an animal, a chamber in the applicator pad communicating with the liquid-permeable base, a cylinder leading by way of a first non-return valve to the chamber, a replaceable liquid cartridge comprising a body serving as a handle for the applicator, and a neck slidable in the cylinder as a plunger, a second non-return valve normally closing a liquid outlet from the neck and adapted, when the plunger is retracted in the cylinder, to unseat allowing passage of fluid from the cartridge to the cylinder and, when the plunger is advanced in the cylinder, to close and force liquid from the cylinder, unseating the first non-return valve, and into the chamber in the applicator pad, the liquid cartridge being screw threadedly engaged in a sleeve slidable but non-rotatable on the cylinder, adjustable stop means being provided for said sleeve, said adjustable stop means including a stop nut threadedly engaged on the sleeve which when the plunger is in its advanced position abuts the applicator pad, the liquid-permeable base being liquid-permeable by virture of a plurality of holes therethrough, and a multiplicity of removable plugs blocking the holes whereby when appropriate plugs are removed, a flow of liquid can occur in a desired outline.
Claim 2
Dependent Claim 229 words
An applicator for impressing liquid brands or medicaments on animals including: an applicator pad having a liquid permeable base free of any needles for surface application to an animal, a chamber in the applicator pad communicating with the liquid-permeable base, a cylinder leading by way of a first non-return valve to the chamber, a replaceable liquid cartridge comprising a body serving as a handle for the applicator, and a neck slidable in the cylinder as a plunger, a second non-return valve normally closing a liquid outlet from the neck and adapted, when the plunger is retracted in the cylinder, to unseat allowing passage of fluid from the cartridge to the cylinder and, when the plunger is advanced in the cylinder, to close and force liquid from the cylinder, unseating the first non-return valve, and into the chamber in the applicator pad, the liquid cartridge being screw threadedly engaged in a sleeve slidable but non-rotatable on the cylinder, adjustable stop means being provided for said sleeve, said adjustable stop means including a stop nut threadedly engaged on the sleeve which when the plunger is in its advanced position abuts the applicator pad, the liquid-permeable base being liquid-permeable by virture of a plurality of holes therethrough, and a multiplicity of removable plugs blocking the holes whereby when appropriate plugs are removed, a flow of liquid can occur in a desired outline.
Claim 3
Dependent Claim 71 words
An applicator according to claim 1 wherein: there is applied to the liquid-permeable base a stencil sheet formed with said multiplicity of plugs entering and blocking certain of the holes through the base and with a part excised to form at least one channel into which the remainder of the said holes lead and defining the configuration of the area over which liquid is to be surface applied to an animal.
Claim 4
Dependent Claim 32 words
An applicator according to claim 1 wherein: spring loading means urge the sleeve and the cartridge engaged therewith to retracted position, and lugs limit the retraction of the sleeve on the cylinder.
Claim 5
Dependent Claim 37 words
An applicator according to claim 1 wherein: the stop nut limiting the advance of the sleeve on the cylinder is adjustable and adapted to vary the stroke of the handle and associated plunger relative to the cylinder.
