Safety sealed bottle stopper
View Patent ↗A safety sealed bottle stopper in the form of a one-piece unitized fusion over-molded injection molded component comprising an exterior housing having multiple sealing fins forming an internal liquid leakproof engagement with the interior bottle neck of a liquid medication bottle container and having an upper entrance port and a lower fluid flow path with a valve positioned between the lower fluid communication path and the upper entrance port. The upper entrance port is configured to form a liquid tight engagement fit only with an oral/enteric tip syringe and not with an I.V. (intravenous) luer slip tip syringe to indicate to the user that the stopper is only to be used with an oral/enteric syringe and not an I.V. luer slip tip syringe as a safety feature which is especially useful when the stopper is used as part of an infant's or child's liquid medication bottle container.
1. A safety sealed bottle stopper for use with a liquid filled bottle container having a cylindrical neck opening, said stopper comprising:
a rigid exterior housing forming a liquid tight engagement with said cylindrical neck opening;
said housing having an upper entrance port;
a lower communication path; and
a resilient split septum valve having a valve slit which defines two valve edge surfaces that are in face-to-face sealing contact with each other, said valve positioned between said lower communication path and said upper entrance port, said valve slit biased to a compressive back pressure resistant normally closed sealed position by said stopper exterior housing including means in conjunction with said cylindrical neck opening for applying an inward compressive force to said valve edge surfaces so as to bias said valve slit to a closed position wherein said valve prevents spillage or leakage from said bottle when said liquid filled bottle is inverted and/or squeezed.
2. The stopper of claim 1 , wherein said valve comprises a resilient synthetic rubber material.
3. The stopper of claim 1 wherein said stopper is utilized in conjunction with an oral enteric syringe having a conically tapered tip dimensioned greater in diameter than an I.V. luer conically tapered tip.
