Abstract: A tamper-resistant closure for a medical injection device such as a syringe includes a cap having both a blind bore sized to receive and seat tightly against the syringe tip, to prevent material from entering or being withdrawn from the device. The cap has a threaded connection to the syringe tip, and is entirely covered by a loose-fitting shield having a one-way drive mechanism which prevents the cap from being unscrewed from the device while the shield is in place. The shield has at least one internal, frangible tang protruding obliquely into the envelope of the cap, so that the shield and cap can be easily assembled, but cannot thereafter be disassembled without breaking the tang and thus providing an indication of tampering.

Abstract: A child-resistant, two-piece closure is formed with a resilient wedge in the outer cap member which can be pressed into interlocking relationship with an upstanding locking lug element of the inner cap member to facilitate rotational movement in the closure loosening direction by a healthy adult. An aperture is provided in the outer cap member so that a pencil may be radially inserted therein and into contact with the upstanding locking lug element so as to interlockingly couple the outer cap member and inner cap member for rotational movement in the closure loosening direction with the pencil by an elderly or handicapped individual. The child-resistant closure serves as a duel function device by allowing push-in and turn closure removal by healthy adults and easy removal with an inserted pencil or the like by elderly or handicapped adults while still being resistant to removal by young children.

Abstract: A two-piece child resistant closure having projections on the top of the inner cap. These projections are accessible through the open center of the outer cap top to assist the user in unthreading the container. This provides a user friendly closure for the elderly and arthritically impaired while still maintaining the usual child resistant opening feature, which can, for example, require a simultaneous push and turn movement.

Abstract: A captive key release closure structure includes a base ring for connection to a rim of a container, a closure member or cap integrally hinged to the base ring, latch indentations on an outer surface of a neck wall of the base ring, and latch pawls on an inner surface of a depending circumferential wall of the cap and aligned with the indentations. A key slot is formed in the cap wall at a position opposite the hinge, and a key receiving recess is formed in the base ring. The latch indentations and pawls are positioned in sets on opposite sides of the key slot and key recess. The closure structure is opened by insertion of a small keylike tool, such as a coin, spoon, or the like, and twisting against the surfaces forming the key slot and recess to separate and thereby release the pawls from the indentations.

Abstract: A tamper-proof closure 10 is inserted by means of positioning tool 20 into a nuclear fuel consolidation storage canister 30. The closure 10 includes a grooved weakened portion 44, which if it exceeds its elastic limit when the base 12 is flexed during removal attempts will indicate any attempts to remove or otherwise tamper with the thus closed canister. Locking tabs 18, on transverse legs 13 and 14 extending from base 12 are engaged in slots 40 in the wall of the opening of canister 30 when the closure 10 is in fuel storage position. Tool 20 has a portion 46 which enters a slot 48 in base 12 at 90.degree. to its working position and then twists to engage spanning portion 42's flanges 43 in slots of flanges 16 on the legs 13 and 14 to retract tabs 18. The base is prevented from flexing on insertion into the container opening by support it receives from portion 46.

Abstract: A floating container cap for liquid storage containers used adjacent to bodies of water or similar liquids, the storage containers having a cylindrical input port of a predetermined internal diameter with a threaded surface for interaction with the container cap, comprising a cylindrical housing which is fluid tight with an external diameter less than the container input port. A generally circular metallic top having a diameter larger than the remainder of the housing forms a top end of the housing and a foam material is disposed inside the housing. To removably secure the cap in place, a plurality of threads are disposed on the outside of the housing adjacent to the top for interfacing with the input port threaded surface.

Abstract: A bottle includes a mouth and a neck adjoining the mouth. The neck has helical ribs on the outside to permit application of a peripherally indented, screw-on crown. The main body of the bottle has a base, which is provided with an upward recess. A plurality of inwardly projecting ribs is provided around the periphery of the recess, each rib being convexly rounded and devoid of points, and having two concavely rounded shoulder portions on either side, so that stress concentration is minimized. The recess is sized to receive a peripherally indented crown of the same size as that receivable on the neck, so that the ribs register in at least some of the peripheral indentations. Thus, one bottle can serve as a crown remover for another, without a significant risk that the ribs will break or crack.

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 closure includes a plurality of tabs extending upwardly from its top wall to enable manual application of torque to the closure without gripping of the side wall thereof. The preferred tabs have surfaces defining a plane for supporting the closure in an inverted position for installation of a liner, and do not extend radially beyond the side wall of the closure.

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 decomposition vessel comprises a rigid bucket of a plastic material resistant to chemical attack, totally enclosed in a supporting metal vessel which consists of a cylindrical supporting member and of a flat cap adapted to be screwed onto the supporting member so as to close the vessel tightly. Sealing means are provided between the opposed flat faces on the cap and the supporting member in the form of a sealing disc adjacent the flat cap and an outwardly exending flange integral with the rigid bucket in contact with the disc and with an upper planar face of the supporting member.

Abstract: A toilet bowl cleaning means wherein a container is located within a water tank associated with the bowl with a cleaning compound such as calcium hypochlorite included within the container. A plurality of openings are provided, and this provides exposure to water in the tank so that the compound will be dissolved in the water and thereby delivered to the bowl when the toilet is flushed. The openings may be formed in a centrally located cylinder with the compound located within the cylinder and with a water space between the cylinder and the outer container walls. Controlled amounts of compound are thereby released to the water in this area.

Abstract: A threaded lid for closing the opening in a pump housing having a body portion and a gripping formation defined by a ridge on the body portion having a central portion and projections extending beyond the central portion. A juncture between the central portion and each of the projections varies gradually from a rounded angle at one terminus of the juncture to a gently sloping ramp at the other terminus of the juncture, so that a simple elongated tool such as a stick may be placed between the projections of the gripping formation and rotated to loosen the lid, but not to tighten it. Furthermore, the mildly curved S-shape provides surfaces which conform to the hand to enable substantial manual loosening force to be applied comfortably to the lid, whereas the surfaces of the gripping formation engaged by the hand to tighten the lid are not conducive to the application of a substantial amount of manual force.

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: In a stopper arrangement for bottles of the type having an externally threaded neck closable by a synthetic plastic screw cap, the screw cap has an approximately cylindrical internally threaded wall part which is closed by an upper lid surface. The screw cap is so dimensioned and configured, and is formed of such an elastic plastic material, that the cap can be removed by unscrewing, or can be removed by a conventional crown cork opener. In either case, the cap can be used to re-close the bottle, since it is specially constructed so as not to be destroyed if removed by a crown cork opener.

Abstract: A base is securable to the lid of a conventional container assembly which also includes a vessel. The base includes an inwardly directed flange which abuts the top panel of the lid and a downwardly directed flange which encircles the skirt of the lid. Upstanding from the base are lugs which provide diametrically opposed shoulders for receiving a leverage tool for the purpose of rotating the lid relative the vessel.

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 screw-on jar top having opposing ears formed from jar top side material and protruding above the edge of the top is disclosed, while the seal between the top and the jar is maintained. The ears are shaped to receive a leverage-applying member to permit easier opening of the top when it is tightly screwed on, and to permit stacking of jars without interference from the ears.

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.

Abstract: Plugs are fitted in the thumb and fingerholes of a bowling ball so that when the fingertip enters it will touch the plug at the precise time that the finger has reached the depth found by the bowler to be most comfortable and satisfactory. The plug has a spiral passageway therein useful with a spiral removal tool for repeated non-destructive removal of the plug for cutting it to shorten it, followed by re-installation of the plug and eventual sealing in the hole when the proper fit is achieved.

Abstract: A plastic stopper is used for small-diameter bottle necks such as are conventionally closed by corks. A top disk is annular in that a central hole is formed and below the disk is a pocket having an inside diameter coinciding with the central hole. The pocket is closed at the bottom. The pocket is dimensioned to receive a standard corkscrew with a tight enough grip to permit the stopper to be drawn. The disk also has a peripheral depending skirt having an outside diameter such that it fits tightly in the bottle neck. The lower outer edge of the skirt is tapered to facilitate seating. An annular space below the disk between the skirt and the pocket affords flexibility to the stopper for seating and pulling and also can be partially filled with liquid to reduce the amount of air in the headspace of the bottle.

Abstract: A cap, which in addition to serving to removably seal a container, also acts as a carrier for torque-applying means that permit the cap to be released from a stuck position. The cap of the present invention is particularly well adapted for use on containers holding a lacquer based fingernail polish, although not restricted to such use. Caps on containers holding a lacquer base fingernail polish are notorious for tending to remain in a stuck position thereon, and to such an extent that pliers must be used to grip the cap and initially rotate the latter relative to the container on which it is mounted.

Abstract: A safety container closure for small plastic medicine bottles. A plug is inserted into the top or neck, in a tight friction-fit. The plug carries a key recess. An outer cap fits over the top of the container, and carries a key molded to it. The key is placed into the recess, and the plug engaged for withdrawal.
