Tamper resistant closure member
First Claim
1. A tamper resistant closure member adapted to be affixed to a dispensing container having an opening therein, which container is for holding solid dosage forms comprising:
- an inner housing adapted to be fixedly mounted to an opening of the dispensing container, said inner housing having an end wall defining an interior surface towards said container and an exterior surface away from said container, said end wall including an opening therein through which the solid dosage form may pass, said exterior surface having a recess thereon, said recess having a forward wall and a terminal wall, said recess being positioned about said inner housing opening with said forward wall in close proximity to said inner housing opening and extending across said inner housing opening to said terminal wall positioned away from said inner housing opening,obstruction means cooperating with said inner housing opening within said recess, and resiliently fixed towards said forward wall of said inner housing, to permit said obstruction means to move from a first closed position over said inner housing opening to a second open position,an outer housing rotatably affixed to said inner housing, said outer housing having an end wall defining an interior surface towards said inner housing and an exterior surface away from said inner housing, said outer housing end wall having an opening axially positioned to cooperate with said inner housing opening on said inner housing end wall, said interior surface of said outer housing including projection means thereon adjacent to said outer housing opening and adapted to be received in said recess to engage and substantially close said obstruction means as said opening of said outer housing is rotated in communication with said recess to permit a dosage form to exit through said outer housing opening, said projection means for engaging foreign objects inserted in said outer housing opening and impacting said foreign objects upon said terminal end of said recess; and
,ratchet means affixed to said inner and outer housings thereby permitting said outer housing to rotate only in one direction relative to said inner housing.

Abstract
A tamper resistant closure member adapted to be affixed to a dispensing container includes an inner housing affixed to the opening of the container. The inner housing has an opening and a recessed portion about the opening. A leaf member is positioned over the opening within the recess and is secured about its edge surface to the inner housing. An outer housing is rotatably nested over the inner housing. The outer housing includes an opening and a projection adjacent the opening. The projection is adapted to be received within the recess to engage and substantially close a leaf member as the opening of the outer housing is rotated in communication with the recess.

16. A tamper resistant closure apparatus for holding at least one solid dosage form comprising:
-
a dispensing container having an opening and a rim; a cylindrical inner housing adapted to be affixed to the opening of said dispensing container, said inner housing having an end wall and a cylindrical wall, said end wall having an interior surface towards the container and an exterior surface away from said container, said end wall including an inner housing opening through which said solid dosage form may pass and said exterior surface having a recess therein, with said recess having a forward wall and a terminal wall, and said recess positioned about said inner housing opening, with said forward wall of said recess in close proximity to said inner housing opening and said recess extending across said inner housing opening to said terminal wall positioned away from said inner housing opening; inner housing affixing means including tongue and groove surfaces about the interior cylindrical wall of inner housing and the outer surface of said dispensing container rim; a leaf member having edge surfaces thereon positioned over said inner housing opening within said recess and resiliently affixed about one of said edge surfaces towards said forward wall to permit said leaf member to move from a first closed position to a second open position over said inner housing opening; an outer housing rotatably affixed to said inner housing, said outer housing having an end wall defining an interior surface towards said inner housing and an exterior surface away from said inner housing, with said outer housing end wall having an outer housing opening axially positioned to cooperate with said inner housing opening on said inner housing end wall and with said interior surface of said outer housing including projection means adjacent to said outer housing opening adapted to be received in said recess to engage and substantially close said leaf member as said outer housing opening is rotated in communication with said dispensing section to allow a dosage form to exit through said outer housing opening, said projection means for engaging foreign objects inserted in said outer housing opening and impacting said foreign objects upon said terminal end of said recess; and
,ratchet means affixed to said inner and outer housings allowing said outer housing to rotate in one direction relative to said inner housing, said outer housing opening preceding said adjacent projection as said outer housing is rotated past a fixed position on said inner housing. - View Dependent Claims (17)
