Patent attributes
A closure assembly for a medical dispenser having tamper evident characteristics including a flexible tip cap dimensioned to be independently used with different sized medical dispensers. The tip cap is operatively disposed in enclosing relation to a discharge port of the medical dispenser and a retainer is disposed in surrounding relation to said tip cap concurrent to the operative disposition thereof relative to the discharge port. The retainer includes a clamping structure disposed in clamping relation to an exterior of said tip cap, wherein the clamping relation disposes the interior of the tip cap into fluid sealing engagement with the discharge port. After removal of the discharge port, reinsertion thereof is prevented by deformation of the tip cap into an insertion blocking concurrent to maintenance the clamping relation.
