Abstract: An animal proof container is set forth. The container comprises a can having a bottom, a sidewall having an inside surface having a plurality of substantially flat portions each having a recess defined thereby, an outside surface having a corresponding plurality of holes communicating to the recesses and a rim defining an open top. A lid of the container has a cover portion adapted to cover the open top of the can and a plurality of members extending downwardly peripherally from the cover portion, fitting adjacent the inside surface of the can and having lower end portions adjacent the flat portions of the inside surface, the lower end portions being biased outwardly towards the flat portions sufficiently to proceed into the recesses when the lid is pushed fully downwardly onto the can. The lid is biased normally upwardly relative to the can sufficiently for preventing the lower end portions from entering the recesses.

Abstract: A screw top closure is provided with a freely rotating ring surrounding its periphery thus preventing the user from rotating the closure by gripping the periphery. The ring is captivated on the closure and cannot easily be removed. The closure is provided with a key way on its upper surface which the user can engage with a key which is accessible only to authorized users.

Abstract: A two-piece, press-twist, child resistant closure is formed with upwardly extending lugs, protrusions, ribs or channels on the upper surface of the outer closure member. The lugs assist in holding the outer closure against rotation while being axially depressed to engage the inner closure so that rotation of the container relative to the closure will effect removal of the closure. The closure system serves as a convenient system for arthritic or manually handicapped adults to use and still retain the child resistant nature of the closure for bottles containing harmful products.

Abstract: The tube has a peg-shaped neck extension (3) at its upper end, which contains a predetermined breaking point (4). The neck extension (3) is generally positioned under the removable protective cap (7). A short socket (9) is formed on the upper side of the cap (7) in an axial direction, the interior diameter of which is slightly greater than the diameter of the neck extension (3). The inner surface of this socket (9) and the outer surface of the neck extension (3) are provided with corresponding notch flanges (5) or notch grooves (10), such that the cap (7) and the neck extension (3) are non-positively connected to each other when rotated about the longitudinal axis, when the cap (7) with the socket (9) is positioned on the peg-shaped neck extension (3). If the cap (7) is rotated in this position about the longitudinal axis with slight pressure simultaneously exerted then the peg-shaped neck extension (3) is sheared off at the predetermined breaking point (4) and the tube is thereby opened.

Abstract: A cap for a fuel tank has a cap body for screwing into the filler neck of the fuel tank with an "O" ring interposed therebetween, and a lid member for mating to the cap body, both the lid member and the cap body having coacting structure for mutual interengagement to maintain the lid member normally mated to the cap body but separable in break-away relationship from the cap body to leave the cap body intact within the filler neck upon application of external force, such as through collision, to the lid member. The coacting structure may take the form of engaging recesses, holes or grooves on one member and of engaging projections, tabs or pins on the other member.

Abstract: The present invention provides a closure for a container. The closure is provided with a tunnel member into which any appropriate implement such as the handle of a teaspoon can be inserted when it is desired to manipulate the closure e.g. for opening. The provision of the tunnel member is of great assistance to people lacking in manual dexterity.

Abstract: A tamper-indicating closure comprising a disc-shaped top with an upper skirt extending downwardly from the top; an annular upper bead around the inner surface of the upper skirt; a lower skirt proximate to and in center alignment with the upper skirt, the upper skirt being disposed between the top and the lower skirt; an annular retention bead around the inner surface of the lower skirt; a breakable bridge means between the skirts as the sole connection between the skirts; and a tool aperture between the skirts adapted to accept a tool means for breaking the bridge means so as to part the skirts.

Abstract: This bottle has a projection or "latch" from its neck, just below the thread, and along and near the lower end of that thread. There is a gap in the cap thread, that lines up with the "latch" when the cap is fully screwed on. The cap deforms when screwed on, passing the "latch" over the end of the cap thread and into the gap. The "latch" then resists cap removal. Only torque beyond the ability of a small child (or even requiring use of a tool) frees the cap. A second projection from the neck, a "flag", is breakable. It is below the bottom end of the neck thread, just above (measured along the thread) the "latch". The "flag" can fold against the neck, but springs out if released. It catches in the cap-thread gap when the cap is unscrewed, and is torn off or broken by forcible removal of the cap. Its removal or breakage evidences that the bottle has been opened.

Abstract: A key operated security cap structure for a container, such as a medicine bottle, having a neck defining an opening for the container comprises a cap member for fitting over the neck of the container in a manner precluding removal of the cap member during normal usage of the container, the cap member having an internally threaded cylindrical portion extending above the rim of the container, a cylindrical externally threaded plug for threading into the cap member to a terminal position wherein the outer surface of the plug is substantially flush with the rim of the cap member, the outer surface of the plug being formed with a pair of diametrically spaced key-receiving recesses, and a key having a pair of projections fitting in the plug recesses to provide a means for removing the plug and opening the container.

Abstract: A child proof medicine vial is provided having a bead for mating in a recess in a flange in the cap whereby the cap is tightly secured to the vial. The cap is provided with a recess and complimentary slots and inner chamber whereby a panel may be slidable into and out of the cap. When the panel is fully inserted in the cap, there are no projections on the cap for facilitating removal of the cap from the vial. When fully retracted from the cap, the panel permits the user to raise the cap thus permitting access to the vial. When fully retracted, the panel may have indicia to the effect that the vial is nonchild proof.

Abstract: A reusable childproof container closure is disclosed for closing the nozzle of a plastic container wherein the container terminates upwardly in a nozzle including a peripheral groove. A plastic closure includes an inserting member having a cooperating, peripheral lip formed therein for removable engagement in the peripheral groove.

Abstract: A single service childproof container closure for closing the nozzle of a plastic or other container comprising a non-removable closure having a non-replaceable breakaway cap for implant into the nozzle of a container.

Abstract: An openable discharge closure is provided, for silo bottom unloaders, in which the closure comprises a door-like member that is moved vertically downwardly and transversely away from the discharge opening. A sweeper or broom may be mounted for engagement by the upper surface of the closure as it moves laterally away from the opening. The motion of the closure is controlled by a single drive mechanism that provides both vertical and pivotal movement, with the vertical movement enabling the door to move upwardly or downwardly, and the pivotal movement enabling the door or closure to move transversely.

Abstract: A one-piece child-resistant dispensing closure for a container which has an open end. The closure has a skirt which mates with the end of the container and a top which spans the space defined by the skirt. Preferably there are two dispensing openings through the top, each of which is surrounded by an upwardly extending rim. The closure also comprises a lid for each opening and a hinge for each lid. The hinges and lids are integral parts of the closure. The lids have similar rims which fit around the rims on the closure top when the lids are swung over to close the dispensing openings. In the closed position, ribs on the edges of the pairs of opposed rims snap over each other and ears on the inner sides of the lids are closely spaced from a fulcrum on the closure top. The engagement of the ribs holds the lids closed. Pry means, such as a coin or blade, may be inserted between the fulcrum and a lid ear to pry the particular lid open.

Abstract: A child-resistant/non-child-resistant dual function double cap closure with incorporated means for over-ride of conventional normally disengaged torque couplings includes a hole formed in the top surface of the outer cap, a formed plug having a locking protuberance and removal ring, and a plurality of spaced stop lugs formed annularly on the top surface of the inner cap. The free and separate movement of the outer cap is prevented in either direction of rotation by the plug's insertion into the hole of the outer cap as to place the base of the plug in the space between the stop lugs of the inner cap rendering the cap non-child-resistant at the time of consumer purchase. The consumer may use the cap in a non-child-resistant mode or remove the plug thus converting the cap to a child-resistant mode.

Abstract: A child-resistant closure and container system is provided with a snap on and off closure requiring a coin or tool to remove the closure. A skirt wall on the closure is positioned sufficiently close to a shoulder on the container that the gap between the bottom edge of the skirt wall and adjacent shoulder is insufficient to admit a tool or to allow the teeth of a child to enter and to be used to pry off the closure. The shoulder diameter is equal to or greater than the diameter of the skirt wall to prevent the child's teeth from engaging and prying off the cap. A small notch is formed in the skirt wall to allow a coin or tool to be inserted and to be twisted against the shoulder to pry off the closure.

Abstract: The present invention pertains to releasable locking mechanism for a hollow circular member such as a fill pipe for an oil tank and cup-shaped closure cap of non-magnetic material which is connectable to the hollow circular member, in combination with a locking member of ferrous material supported by said cap for axial movement vertically relative to the cap and hollow circular member but non-rotatable relative to the cap, one end of the locking member having a configuration that is engageable with the hollow circular member in non-rotatable relationship to prevent rotation of the cap with respect to the hollow circular member when the locking member is in the latter position, the locking member being adapted to be raised from said locking engagement with the hollow circular member by a magnet which may be mounted within a wrench for use with the cap to remove the same from the hollow circular member.

Abstract: A closure assembly for a bottle or container which has a cylindrical neck portion and a lid with a skirt. The lid skirt is detachably fitted to the neck portion by cooperating beads on it and a cylindrical collar which is securely mounted on the neck portion by transverse members. The collar is disposed at a radial distance from the neck portion and encloses at least part of the skirt. The transverse members are adapted to cooperate in a camming manner with one or more projections on the skirt so that turning of the fitted lid relatively to the neck portion results in an axial displacement of the lid. The lid is constructed to be turned by an implement such as a T-shaped handle key or a coin. For this a slot can be provided disposed along a diameter. The inside of the lid can be formed with projecting wall members defining an inwardly closed cavity around the slot with shape of a narrow cylindrical section.

Abstract: A child-resistant container, e.g. a child-resistant medicine bottle, comprises in combination a container having a neck, a plug or other closure insertable in the neck with the plane of its upper surface extending not substantially beyond the plane of the upper surface of the neck, and rotary interengaging means interengaging the closure and the container neck. A key adapted to overlie the closure has gravity-actuated pin and socket means capable of releasably interengaging the closure and the key. Upon application, the key is operative to engage the closure with the neck and to disengage it therefrom.

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 plug fitment adapted to be removably inserted in a circular port to seal same in a substantially air tight manner comprises a somewhat flexible body of generally cylindrical shape. The body has an open upper end and an interior region bounded by an inner wall and communicating with the open end and has a vertical axis. The upper end has a circular peripheral lip lying in a horizontal plane and having an inner periphery defining the periphery of a circular opening centered on said axis. Slightly flexible means disposed in said upper end and said region includes a vertical member spaced from the inner wall and aligned with said axis. The member has a top end disposed below said horizontal plane. The member has a vertical slit extending downwardly from the top end to a bottom position intermediate the top end and the bottom of said member. A circular generally flat slightly flexible key disc is disposed horizontally and removably in said opening.

Abstract: A child proof medication bottle including a female, interiorly threaded opening adapted for dispensing medication in pill form or similar use, provided with a male, externally threaded cap, inserted into the female opening. On insertion, the male cap or plug is received within the opening to a depth wherein only a hemispherical projection is exposed outside the confines of the bottle. This smooth hemispherical projection lacks the necessary grasping surfaces for withdrawal thereof and is thus rendered child proof. The bottom end of the bottle is similarly shaped in the form of a hemisphere adapted for receipt in the interior of the cylindrical key structure provided with a flat end for upright support and including two key elements insertable into corresponding slots formed in the hemispherical surface of the cap. Thus the cylindrical key structure may be utilized to open providing a reminder to the user to return the key to its stored position.
