Abstract: A closure system for threaded containers wherein the closure is of the dispensing type and is child resistant in two aspects. Interengaging lugs on the closure skirt and container neck are so arranged that a squeezing force is required to permit the closure being unthreaded from the container. A dispensing opening in the closure top is closed by a hinged cap that meets with the upper rim of the closure in a parting line. At this parting line both the hinged cap and the top of the closure have matching protruberances that require the squeezing of the lower one in order to push up or release the cap. The plastic material of the cap and the closure are sufficiently strong that a child is unable to flex or squeeze the closure enough to open the cap or unthread the closure from the container.

Abstract: A container closure attachable directly or indirectly to a container neck sealed by means of a pierceable film seal. The provision of a film seal covering the container neck guarantees the user that the contents of the container are authentic and original as supplied by the manufacturer. The film seal is pierced as the closure is adjusted from an intact to an access position on the container neck. In the upper intact position, a safety band remains intact. The closure can be adjusted to the lower access position only after the safety band has been removed, and the film seal is pierced as the closure is adjusted to the lower access position. Ratchet-like serrations may be provided on the inner side of the safety band engaging the container, thus making it impossible to unscrew a screw-type closure without removing the safety band. The safety band may be provided on a separate intermediate piece which may be snap-fitted or screwed onto the container neck.

The container has a plurality of projecting anti-rotation teeth positioned below the bottom of the closure cap and an overcap is adapted to be snapped over the closure cap, the overcap having a skirt with inner diameter projecting anti-rotation ribs which index with the container teeth to prevent rotation of the overcap. The overcap is effective to prevent opening of the orifice and is provided with frangeable connecting portions allowing a part of the overcap to be removed from the assembly to provide access to the closure cap for an opening actuation of the closure cap. The overcap skirt is provided with an inner diameter ledge which abuts a closure cap outer diameter ledge to prevent removal of the overcap skirt.

Abstract: A two-piece dispensing closure in which a relatively soft inner seal member is positioned beneath a rigid outer closure member. The inner seal member effects a seal between the outer member and the neck of the container, and enables the parts to be snapped together. Further, the closure may be snap fitted to the container, which may have either an injection blow molded neck finish or an extrusion blow molded neck finish. In one form of the invention, a pivoted plug is carried by the outer member for insertion in an opening formed in the inner member. In another form of the invention, the plug is fixed relative to the outer member and the inner member flexes relative thereto. In a still further form of the invention, the outer member has a valve seat and the flexible inner member carries a plug for cooperation with the seat.

Abstract: A tamper evident closure for a container having a closed endcap with an overcap to coaxially rotate thereabout. The overcap is provided with an integrally formed knife blade which is constructed and arranged to engage a weakened annular band in the container wall near the endcap. The knife blade is located within a well which is an integral part of the overcap. As the overcap is rotated, the knife blade engages and severs the annular band, and separates the closure including the endcap and the rotatable cap from the body of the container. An annular channel may also be provided to support the overcap during rotation and thus maintain the alignment of the blade with the weakened annular band.

Abstract: A one piece plastic closure comprises a base which is attachable to a container and a cap attached to the base of the closure by a hinge. A safety band is molded together with the base, to which it may be attached by webs. The safety band overlays approximately half the perimeter of the cap and its height is generally the same as that of the cap itself. In this way, the cap cannot be grasped in the area opposite the hinge, and thus cannot be opened. A lug may additionally be provided on the cap which is engageable in a corresponding recess in the safety band to provide the closure in a closed and sealed condition, thus holding the closure and preventing it from opening under the effect of excess pressure in the container.

Abstract: An injection-molded thermoplastic closure with shake-and-spoon apertures and associated flaps for selectively closing and opening the apertures. The flaps are releasably retained in their closed positions by catch elements which provide retention forces that are relatively insensitive to dimensional and shape variations in the body resulting from the molding process. In one embodiment, the cap has "freeze points" and a gate location that reduce the tendency of the cap to assume an oval condition when cooled from molding temperatures. A wide sealing ledge cooperates with a central support for a liner seal positioned in the cap to seal the mouth of a container.

Abstract: A dispensing closure having a base cap with a top containing a dispensing orifice and a skirt adapted to be attached to a container so that dispensing of the container contents can take place only through the cap orifice. The orifice is sealed with an integrally molded removable disc having a spiral weakening groove which defines a tear strip. Lifting a pull ring attached to the tear strip removes the sealing disc as a spiral strip so that any attempt to hide a previous partial opening by pushing the lifted portion of the strip back in the plane of the disc will be easily detected. A lid attached to the base cap provides easy access to the seal for detecting tampering and removal for use as well as acting to close the orifice after removal of the sealing disc.

Abstract: A closure device for a container is described consisting of a cap for a container and a cap lid which is pivotably mounted on the cap. The cap lid has an encircling circumferential border which projects downwardly from the upper surface of the lid. The border is a curved spherical surface segment and the cap defines a cup-shaped recess which is complementary in shape to facilitate sealing. The center of curvature of the spherical surface segment is located on the pivot axis of the cap lid. A pair of supporting plates are formed on a base portion of the cap and are guided in the pivot plane of the cap lid by parallel guide ribs so that the cap is non-rotatably mounted and pivotably mounted reliably in the recess and is sealed in every operating position relative to the container cap.

Each of the first and second parts comprises a base wall and a peripheral skirt. A pair of hinge straps extends from the skirts and are positioned on opposite sides of the integral hinge. The radial length of the pair of hinge straps is less than the length of the arc through which the second cap part moves to and from and closed position relative to the first part such that the pair of straps stretch to function as springs. The ends of the pair of straps are attached to the skirts radially inwardly of the periphery of the skirts.

Abstract: A generally cylindrical closed ended molded plastic cap for use in a liquid storing container includes a planar sealing surface at the closed end which defines a tab recess. A substantially planar molded plastic tab configured to be pivotally mountable within the tab recess is snap fitted to the cap and is pivotable between a first position in which the cap seals the liquid storing container and a second position in which the liquid may be removed from the container. A pair of tines on the tab cooperate with a corresponding pair of grooves in the tab recess to resist stresses which tend to separate the tab from the tab recess.

Abstract: This invention comprises a two part closure, for a container, comprising a top cap hingedly connected to an inner cap which is adapted to be semi-permanently positioned over the mouth of an associated container, a depending skirt on the inner cap and a trigger forming part of the skirt of the inner cap, actuation of the trigger normally being prevented by engagement of the trigger with an arcuate bead on the outside of the associated container whereby the trigger forms a locking means to hold the top cap in its closed position until the closure is angularly displaced relatively to the container into a predetermined position in which the trigger is unlocked and can be actuated manually to release the top cap for opening.

Abstract: An integrally molded, unitary, plastic dispensing closure comprising a body, a lid, and a "living" hinge that joins the lid to the body. Cams and cooperating wall surfaces in the vicinity of the hinge provide forces that temporarily deform the hinge, within its plastic limits, and facilitate the movement of the lid to either an opened, or a closed, position. In one embodiment, recesses are formed at the rear of the closure body to accommodate the cams when the closure is in its closed position. In another embodiment, recesses are formed in the skirt of the lid to accept upwardly extending posts, and a cavity is defined in the upper surface of the closure body to accept cams, or lugs, depending below the lid. An efficient, aesthetically pleasing, low profile dispensing closure is achieved in each instance.

Abstract: A one-piece molded thermoplastic child-resistent dispensing closure in which the dispensing opening in the closure is sealed by the downwardly extending projection of a locking flap that is foldably attached to an edge of the closure, in which the top of the closure comprises a recess to receive the sealing flap when it is in its closing position and in which the portion of the recess which is adjacent the free end of the locking flap is deeper than the thickness of the locking flap so that the free end of the locking flap can be depressed within the recess to facilitate the opening of the closure. Certain embodiments are described in which the locking flap is provided with a downwardly depending tab which is received in a recess in the skirt of the closure when the locking flap is in the closed position and which is deflected outwardly from the recess by the depression of the locking flap into the recess in the top of the closure to further facilitate the opening of the closure.

Abstract: A biasing hinge is disclosed which is made up of a first hinge member and a second hinge member integrally hinged together along a curved line. The hinge members are shaped so that when one hinge member is swung relative to the other, the members are resiliently deformed or stressed and energy is stored in said hinge members. This stored energy will bias the hinge members to swing to an open or a closed position depending on which position is nearest said hinge member at a particular time. The hinge can be molded with the hinge members having the desired shape to provide the necessary stresses to provide the desired biasing. The hinge can also be molded as an integral part of a cap or closure.

A tamper-indicating removable strip is integrally formed with the closure and is secured to one of the closure body and closure cover via frangible bridging means. The closure hingedly connects the cover and body. The body defines a dispensing orifice and the cover seals the orifice. The strip defines spaces and the other one of the body and cover defines projections which extend into the spaces to resist relative movement of the body and cover unless the frangible bridging means are severed and thereby shows that access has been gained to the dispensing orifice. The closure is preferably generally circular and the tamper-indicating means are preferably within the perimeter of the closure.

Abstract: This relates to closure assemblies for containers which are subject to tampering. This particularly relates to closure assemblies of the type which include a lever type actuator wherein the lever must be lifted to apply leverage to a closure plug portion to facilitate opening of the closure assembly. Such levers are customarily retained in place by rivets which include frangible portions. This particularly relates to the configuration of such rivets and the details of the lever wherein, once the lever has been pried from its original position and disengaged from the rivet, the lever or an end portion only thereof tilts upwardly due to the non-returnability of the rivet through its original opening thereby to present a visual indication of tampering which can be readily ascertained.

Abstract: A lid made of a synthetic resin and swingable like a cover for a book to open or close the opening of a container. A leg or legs of desired length extending rearwardly from the rear end of a lid plate renders the lid plate capable of maintaining a desired open position, and moving automatically into its open and closed positions. Such capabilities of the lid plate depend on the force created by a flat surface carrying a hinge base to urge the free end of the leg upwardly, the elasticity of a hinge and the hinge base, and the distance defined between the hinge and the free end of the leg which has been moved. The lid is particularly suitable for a compact for a cosmetic, or the like.
