US12429316 - Dosage projectile and method of manufacture
The patent describes a polycell designed for creating dosage projectiles that can remotely deliver biologically active agents to animals, consisting of two semispherical polymer shells that form a hollow body. The components are manufactured through injection or blow molding and are engineered to enhance compatibility and fragmentation characteristics for effective agent delivery.
Claim 1
- A polycell for forming a dosage projectile suitable for administering a biologically active agent to an animal remotely, the polycell comprising: a first component having a semispherical shell formed from a polymer selected from polyamide polymers including those derived from sebacic acid, polymers derived from vegetable oil acids with or without dimerization, terephthalic acid and/or ethylenediamine, polypropylene homopolymers or copolymers, polyphenylene sulphide, polylactic acid, or monomers of ethylene and a structural agent selected from silicon dioxide, sodium carbonate, calcium oxide, magnesium oxide, aluminium oxide, glass spheres, glass bubbles, glass fibres, glass rods, calcium carbonate, and talcum powder; a second component having a semispherical shell formed from a polymer selected from polyamide polymers including those derived from sebacic acid, polymers derived from vegetable oil acids with or without dimerization, terephthalic acid and/or ethylenediamine, polypropylene homopolymers or copolymers, polyphenylene sulphide, polylactic acid, and monomers of ethylene and a structural agent selected from silicon dioxide, sodium carbonate, calcium oxide, magnesium oxide, aluminium oxide, glass spheres, glass bubbles, glass fibres, glass rods, calcium carbonate, and talcum powder; and a filling port in the first component or the second component; wherein the first and second components are formed by injection moulding or blow moulding; wherein the first and second components when joined form a polycell having a substantially spherical hollow body adapted to receive an agent to treat an animal; wherein the polymer of the first and second components is processed to deliver atactic, syndiotactic or isotactic polymerization, subjected to ultra-violet light and/or mechanically stretched in order to develop polymer crystallization and compatibility with the structural agents to produce hydrodynamic fragmentation characteristics in the polycell. a first component having a semispherical shell formed from a polymer selected from polyamide polymers including those derived from sebacic acid, polymers derived from vegetable oil acids with or without dimerization, terephthalic acid and/or ethylenediamine, polypropylene homopolymers or copolymers, polyphenylene sulphide, polylactic acid, or monomers of ethylene and a structural agent selected from silicon dioxide, sodium carbonate, calcium oxide, magnesium oxide, aluminium oxide, glass spheres, glass bubbles, glass fibres, glass rods, calcium carbonate, and talcum powder; a second component having a semispherical shell formed from a polymer selected from polyamide polymers including those derived from sebacic acid, polymers derived from vegetable oil acids with or without dimerization, terephthalic acid and/or ethylenediamine, polypropylene homopolymers or copolymers, polyphenylene sulphide, polylactic acid, and monomers of ethylene and a structural agent selected from silicon dioxide, sodium carbonate, calcium oxide, magnesium oxide, aluminium oxide, glass spheres, glass bubbles, glass fibres, glass rods, calcium carbonate, and talcum powder; and a filling port in the first component or the second component; wherein the first and second components are formed by injection moulding or blow moulding; wherein the first and second components when joined form a polycell having a substantially spherical hollow body adapted to receive an agent to treat an animal; wherein the polymer of the first and second components is processed to deliver atactic, syndiotactic or isotactic polymerization, subjected to ultra-violet light and/or mechanically stretched in order to develop polymer crystallization and compatibility with the structural agents to produce hydrodynamic fragmentation characteristics in the polycell.
