Child Resistant Dosing Adapter Cap

Abstract

A child resistant cap of the type where a first cap is threaded onto a medication bottle and a second cap is normally freely rotatable over the first cap is provided with an elastomeric closure penetrable by the orificed blunt end of a liquid transfer implement such as an oral syringe to allow a dose of medication to be drawn by the syringe from the bottle in an inverted condition of the bottle without significant leakage.

1 . A child resistant self-resealing dosing adapter cap comprising:
 an inner cap having a thread engageable to a threaded bottle neck, a top cap rotatably retained to said inner cap, said top cap being engageable for transferring rotation to said inner cap thereby to screw or unscrew said inner cap to and from a said threaded bottle neck, a self sealing closure through said inner cap and penetrable with the blunt orificed end of a liquid transfer implement such as an oral syringe, and an access hole in said top cap and rotatable therewith into overlying relationship with said closure thereby to permit access to said closure by a said oral syringe.   
     
     
         2 . The child resistant self-resealing dosing adapter cap of  claim 1  wherein said self sealing closure is of elastomeric material and has a septum including a dished central area of minimum thickness sized, shaped and configured to substantially self-reseal following penetration with the blunt orificed end of a liquid transfer implement where said orificed end is of diameter smaller than said septum. 
     
     
         3 . The child resistant self-resealing dosing adapter cap of  claim 2  wherein said closure is pre-slit or pre-cut through said central area of minimum thickness to facilitate penetration by said blunt orificed end. 
     
     
         4 . The child resistant self-resealing dosing adapter cap of  claim 1  wherein said closure is pre-punched or pre-slit through said elastomeric closure from an outer surface of said septum to an undersurface of said closure. 
     
     
         5 . The child resistant self-resealing dosing adapter cap of  claim 1  wherein said closure has a disk shaped interior end operative as a liner between said inner cap and a rim of a said bottle neck. 
     
     
         6 . The child resistant self-resealing dosing adapter cap of  claim 1  wherein said closure has a top rim near to or in contact with an underside of said top cap to help contain any residual liquid against spillage from said closure. 
     
     
         7 . The child resistant self-resealing dosing adapter cap of  claim 1  further comprising a post rising from said cap for generally blocking said access hole in a closed position of said top cap. 
     
     
         8 . The child resistant self-resealing dosing adapter cap of  claim 7  wherein said post is diametrically opposed to said closure on said inner cap to help support said top cap against wobbling on said inner cap. 
     
     
         9 . The child resistant self-resealing dosing adapter cap of  claim 7  wherein said post has a tapered upper edge and said access hole has a tapered inner edge complementing said tapered upper edge for facilitating turning displacement of said top cap over said post. 
     
     
         10 . The child resistant self-resealing dosing adapter cap of  claim 1  wherein said self sealing closure has an upper portion above a top side of said inner cap and a lower portion below an underside of said inner cap, said upper and said lower portion being of diameter larger than said closure hole for fastening said closure to said inner cap. 
     
     
         11 . The child resistant self-resealing dosing adapter cap of  claim 10  wherein said upper and said lower portions are integrally formed with each other as by molding of said closure onto said inner cap. 
     
     
         12 . The child resistant self-resealing dosing adapter cap of  claim 1  wherein said lower portion of said cap is enlarged to serve as a liner between said inner cap and a rim of said threaded bottle neck. 
     
     
         13 . A child resistant self-resealing dosing adapter cap comprising:
 an inner cap having a thread mateable to a threaded bottle neck and a self-sealing elastomeric closure through said inner cap, said closure being penetrable with a blunt tipped liquid transfer implement such as a pipette or the neck of an oral syringe for drawing liquid from a bottle or container mated to said cap, an upper cap rotatably retained to said inner cap, an access hole in said upper cap overlying said closure in a first position of said upper cap; and a post rising from said upper cap for generally blocking said access hole in a second position of said upper cap, wherein said upper cap is normally locked against rotation in one direction relative to said inner cap and releasable from said lock by lifting said upper cap away from said inner cap.   
     
     
         14 . The child resistant self-resealing dosing adapter cap of  claim 13  wherein said closure has a top rim in proximity to or contact with an underside of said upper cap for containing any residual liquid against spillage from said closure. 
     
     
         15 . The child resistant self-resealing dosing adapter cap of  claim 14  further comprising a post rising from said inner cap and diametrically opposed to said closure for generally blocking said access hole in a closed position of said top cap and help support said top cap against wobbling on said inner cap.
