The cap has a base portion fitted onto the neck of the container with an orifice opening through the top surface thereof. The contents of the container are dispensed through this orifice. A first groove is formed around the top surface of the base portion. A top portion removably fits over the base portion in the first groove and also has an opening therethrough. There may be a hinge connecting the top portion and said base portion.

Abstract: A child-resistant package for liquids consisting of a container and a cap therefor. The container has a narrow tubular neck and a protruding concentric spout of diameter less than that of the neck so there is a shoulder at the base of the spout connnecting the spout to the container neck. The spout has an annular lip and a circular rib on its exterior that is located between the shoulder and the end of the spout. The rib has conical upper and lower surfaces which meet at a circular apex. The lower conical surface defines with the neck an angle which is greater than the angle defined between the upper conical surface and the neck. The package includes a cup-shaped cap which fits over the end of the spout.

Abstract: A safety type cap for medicinal and similar containers capable of effecting a tight seal upon the container opening by means of a sealing flange extending laterally from the inner surface of the cap top, and which is deflected centripetally upon contact with the inner surface of the mouth of the container to result in resiliently bowing the top wall of the cap to result in increased outward pressure applied to the flange against the inner mouth surface. The radial thickness of the flange is substantially greater than the thickness of the cap top, so that the flange maintains a substantially undistorted shape during compression.

Abstract: A closure for a container having a neck with an access opening therein and means defining a locking rib on the outer surface of the neck interrupted at least at two circumferentially spaced locations to define gaps therein or predetermined differing arcuate dimensions, said closure including a cap having a top, a skirt depending from the outer edge of the top and at least a pair of primary locking lugs projecting radially inwardly from the skirt which in all positions, except one, engage under said locking rib to secure the cap in place, said primary lugs being of an arcuate span and circumferential spacing to register with said gaps in said one position and at least one auxiliary releasable locking lug of a shallower radial projection than said primary lugs engaging under said bead when said cap is in said one position, said auxiliary lug operable to snap over said bead in said one position when said cap is tilted relative to the neck of the container.

Abstract: A safety cap is adapted to assume a locked position on the neck of a container at which an annular cap rib rides within the concavity provided by an annular neck recess. In order to remove the cap, it must first be pulled outwardly to break this interengagement. Thereafter, the cap need only be rotated or turned to free the cap from neck threads. In order to mount the cap on the container neck, the cap is initially twisted to cause interengagement of the threads of the cap with the threads of the container neck. The threads are so arranged that when the cap rib engages the upper part of the neck recess, the last turn will force the rib into the recess and at the same time clear the threads from one another. In this position the cap will turn freely relative to the neck with the cap rib disposed within the neck recess.

Abstract: A dispensing type container closure having a lid pivotally mounted on the closure so as to be capable of being moved between a closed position in which the lid closes off an opening through the top of the container and an open position in which this opening is uncovered can be made child resistant in character by including a recess in the top of the closure into which the lid is adapted to fit so that in the closed position the lid cannot be manually engaged to be rotated from the closed position. A fulcrum is provided within the recess and the lid is made so that when the lid is in the closed position pressure can be applied to the lid in order to pivot or move a portion of the lid remote from where the lid is hinged on the closure to a sufficient extent so that this portion of the lid can be manually engaged and moved from the closed position. Preferably a toggle structure is employed to connect the lid and the closure so as to hold the lid in either the closed or the open position.

Abstract: A cap and container assembly which is both tamper-proof and child-resistant comprises a container neck with first and second external beads, the first bead extending only part way round the neck and having a lug midway between its ends, and the cap has an internal bead with a gap in it matching the lug and also has a tear-off strip connected to a shoulder that engages under the second bead on the neck so that even after removal of the strip the cap still has to be turned to bring the gap opposite the lug before it can be removed. The shoulder may be on an anchor band which fits permanently under the second bead. The cap may be permanently joined to this anchor band by a hinge web.

Abstract: The disclosure is directed to a child-resistant closure for a container which has a round dispensing orifice defined in a planar end member and one or more recesses defined in the end member adjacent the orifice. The closure member has one or more protruding lugs cooperating with the recesses. When the lugs of the closure are aligned with the recesses of the orifice, the closure may be removed with a relatively small force. When the lugs of the closure are rotated out of alignment with the recesses, a relatively large force is required to remove the closure. The closure need not be oriented with the container for sealing after factory filling.

Abstract: A safety closure for a container which is very difficult or virtually impossible for a child to open but can be easily opened by an adult. The safety closure and container are preferably integrally molded as one piece, and the closure comprises a cap adapted to be secured to the opening of the container by a snap-latch. The cap is released from the container by an inclined ramp on the container adjacent the outer periphery of a rim on the cap. In the method for opening the safety closure, the leading end of the inclined ramp is manually pressed inwardly by a thumb or the like toward the center of the cap and underneath the cap rim. While in this position, the thumb is progressively slid along the container causing the inclined ramp on the container to progressively cam the cap upwardly overcoming the snap-latch and releasing the cap.

Abstract: A pilferproof closure is disclosed having an inner cap and an outer cap. The inner cap is joined together with the outer cap and thus the closure is not removable from a container before the connection between the inner cap and the outer cap has been broken. Inwardly directed projections are provided on said inner cap and arranged to be brought into engagement with the neck of the container to form a childproof reusable closure after the original closure has been broken.

Abstract: An improved package is described of the type used for packaging food products and other products. A molded plastic container is sealed with a closure cap. In order to prevent unauthorized or undetected opening of the container, a tamperproofing means is provided in the form of a tamperproofing band molded integrally with the container. This band is positioned so that it encloses at least the bottom edge of the closure cap skin when the cap is applied to the container. This requires at least a portion of the band to be removed before the cap can be removed from the container.

Abstract: Child-resistant locking means for a twist-action cap for a container. The locking means has two cooperating parts. There is an abutment on the container near, but spaced radially from, the container neck and a tab on the cap which engages the abutment and prevents retrograde rotation of the cap. The tab is flexed inwardly in order to be moved past the abutment both when the cap is screwed onto the container neck and when it is desired to remove the cap from the container neck.

Abstract: A combination threaded cap and neck finish for a liquid container having mating threads on the cap interior and the exterior of the neck and also having second cooperating cam means on the cap and the container neck for applying downward thrust to the cap to maintain liquid tight sealing of the container neck even when the cap is rotated in the loosening direction through an angle relative to the container neck so as to disengage the downward thrusting surfaces of the mating threads. Some embodiments of the invention also have child-resistant cooperating means which prevent removal of the cap unless such means are disengaged by a separate and different manipulation.

Abstract: There is disclosed a safety closure cap for use with a bottle or other container having a neck portion. The closure cap is made of an elastically deformable or expandable synthetic plastic material. The neck portion of the bottle has on its outside a ring-shaped rib flattened at a portion of its circumference. The inside of the skirt of the cap has thereon several radially inwardly protruding lugs. These lugs can be forced to pass the rib on the neck portion in any angular position of the cap relative to the bottle neck by applying axially directed pressure to the closure cap thereby effectively locking the cap to the bottle. There is further provided on the inside of the cap a liner of moisture-absorbing material which is held in position by circumferentially spaced further lugs.

Abstract: A child resistant safety cover for a cylindrical container having a generally annular undersurface located adjacent the top thereof. A cover of this invention can be used with aerosol containers. The safety cover of this invention is formed of a resilient and flexible plastic and has a circular top wall and a tubular wall formed integrally with and depending from the circular top wall. Inwardly extending locking flanges are formed on the lower edge of the tubular wall and are positioned to engage the undersurface of the container when the cover is positioned thereon. Generally diametrically opposed slits are formed in the tubular wall and extend through the lower edge thereof to allow distortion and movement of the locking flanges. Wedging means are carried by the safety cover and are located adjacent to and outwardly of the slits.

Abstract: A bottle or similar container is provided with a safety closure comprising a push-on cap having a sealing plug on its base penetrating into the bottle mouth and having projections on the inside of its peripheral wall which engage behind an annular beading on the bottle neck to retain the cap on the bottle. In addition to the beading, mutually opposite cams project from the bottle neck each providing an upper surface which ascends in a circumferential direction towards the bottle mouth. The peripheral wall of the cap, which is made of a slightly flexible material, is spaced from the bottle neck and at mutually opposite positions on its inside there are inwardly projecting cam followers which clear the cams when the cap is rotated normally but which engage and ride up the upper cam surfaces when the cap is pressed inwards in the regions of the followers and the cap is simultaneously rotated in the same direction as the cam surfaces ascend, thereby pushing the cap off the bottle.

Abstract: A safety closure cap for wide mouth bottles or jars comprising a domed central portion with a depending inwardly directed flange at the periphery thereof, a series of mutually spaced circumferentially arranged slots in said flange; the bottle having a rim and below the rim there is an annular groove defined at both sides by lips sloping up to the edges of the groove, the edge of the flange on the safety cap snapping into said groove and being located in overlapped relation to one of said lips so that it is substantially protected thereby against prying.

Abstract: A unitary reversible closure for containers of medicine and the like is applied in one position to the container to render the container child-resistant and in such position requires a complex manipulation .[.of the closure.]. to release it from the container. In a second position of application to the same container, the closure seals the container but requires only a simple manipulation by the pharmacist to release it from the container, thereby lessening irritation and discomfort to the pharmacist's fingers cause by manipulating closures or caps over a period of time and saving the pharmacist considerable time in removing closures over a period of time to fill the containers.
