Abstract: A twist-off closure is disclosed for all kinds of containers having a head and a closure cap. The container head has at its top end a sealing lip shaped as a circumferential bead. A steep, multiple-start thread is located below the sealing lip. A fin is arranged between each winding of the steep thread and the container shoulder. The closure cap has a corresponding inner thread that co-operates in the closed state with the fins of the container head causing the closure cap to be clamped, so as to prevent the container from being unintentionally opened by itself. In the closed state, the first part of the windings of the thread of the closure cap engage the fins of the container head, and this is clearly perceived as a pressure point when twisting the cap by hand. All that is required to open and close the closure cap is to twist it through a half turn.

Abstract: An anti-backoff screw cap construction for a container neck having a thread with a downwardly-facing pressure face and an upwardly-facing relief face. The cap has a depending skirt having an internal thread with an upwardly-facing pressure face for engagement with the downwardly-facing pressure face of the container neck thread. Engagement results in tightening of the cap on the container neck when the cap is turned in a screwing-on direction. The cap thread has a downwardly-facing relief face having as an anti-backoff structure, an elongate, substantially helical, resilient projecting bead which is integral with the cap thread, the bead being coextensive with an uppermost portion of its downwardly-facing relief face and being directly engageable by the upwardly-facing relief face of the container neck thread. The projecting bead is resiliently deformed by its engagement with the upwardly-facing relief face of the container neck thread when the cap is turned in its screwing-on direction.

Abstract: A container closure system includes a plurality of equally circumferentially distributed pins extending outwardly from the tubular neck of the container near the opening. A detachable cap consists of nested inner and outer cap members. The inner cap member is dimensioned to receive the container neck and includes a plurality of sidewall openings for receiving the pins. The outer cap member has a plurality of locking wedges disposed on its inner surface. The inner and outer cap members are assembled so as to permit mutual rotation. Thus, when the cap is emplaced over the open end of the container, the pins are received in the openings to thereby inhibit mutual rotation between the inner cap member and the container. Then, a twist of the outer cap member in a clockwise direction brings the ramp portion of each locking wedge into engagement with one of the pins, thereby drawing the cap and the tubular member together to effect a secure closure.

Abstract: A plastic container closure has a skirt which is connected to a tamper-evidencing band by frangible bridges, all molded in a single unit. Where the closure is a cap for a container neck, there is at least one retaining means on the skirt and another on the band. The neck has two retaining means which cooperate with those on the cap to prevent upward movement of the cap without fracture of the bridges. To reduce the likelihood of unintentional fracture of the bridges, particularly during installation of the cap on the neck, plural ejection bumpers of extended arcuate lengths are located on the top edge of the band and or from the bottom edge of the skirt and the bridges are located between the bumpers. This snap lock ring functions to replace the conventional retaining means located centrally of the band. The invention is applicable to tamper-evidencing bands of closures and of push/pull closures of sports-type cap spouts.

Abstract: A removal resistant closure cap for a container having a standard threaded neck is disclosed. The cap does not have a thread complementary to the container neck thread but has an inwardly projecting circumferential bead with an intersecting projection extending downwardly from the bead at the helix angle of the container neck thread. When the container neck is engaged by the cap with a threading rotation, the cap projection will engage the container neck thread, and the cap bead will snap over the container neck thread, permanently retaining in the cap on the container neck.

Abstract: An anti-backoff, removable closure for connecting a manually actuated liquid dispenser to a container includes a closure cap having internal threads for mating engagement with similar threads on the outside of the container neck finish, both the cap and the neck finish having mutually engageable ratchet teeth mechanically retaining the closure to the container. The teeth inside the cap each have a trailing face lying in a plane sloping in a loosening direction of the cap relative to the central axis of the cap for producing a camming action between the cap teeth and the neck finish teeth, tending to cam the cap off the container in response to closure unthreading rotation.

Abstract: A molded cap is disclosed having a sealing ring groove just below the cap handle in order to seal crank case gases in an internal combustion engine. The cap includes two spiral grooves for engaging a respective protrusion formed on the inner annular surface of an oil fill snout which receives the cap. A recess is formed at the end of each spiral groove for receiving a respective protrusion to lock the cap into the oil fill snout. The oil fill snout has a draft angle to provide an outside vertical force component on the cap and sealing ring. The vertical force locks the protrusions into the respective recesses and provides a positive sealing force to the sealing ring when the cap is twisted into the snout and into the closed position. The two spiral grooves increase the resistance to back out and create symmetric force components. At the entrance of each groove, a lead-in angle is used to free the cap from the cover by continuing to turn the cap in a counter-clockwise motion.

Abstract: A removal torque-resistant closure and container assembly is provided with the container having a thread extending around the opening. The closure includes a thread for engaging the container thread. The container includes a projection that extends from the thread root between two adjacent thread crests on the container and that defines an outer edge for temporarily deforming the closure thread during relative rotational movement of the container and closure when the container and closure are screwed together. Upon termination of the screwing action, the container projection edge is engaged with a deformed region of the closure thread so as to resist closure removal by unscrewing.

Abstract: The present invention employs a plastic snap-on cap which engages the neck crown and is internally threaded to engage the neck threads of a conventional container. A foam gasket under the top of the cap prevents leakage by sealing against the neck lip. The cap has internal threads which snap over and then engage under the neck threads. Vertical "barriers" below the cap threads prevent unscrewing the cap so long as the cap skirt is intact. Score lines extend from the bottom edge of the cap skirt to above the internal cap bead which engages the neck crown and extend up to the cap threads. A tear tab is used to tear a vertical strip of the skirt which extends up between the score lines. The cap is thus tamper-evident since it cannot be removed so long as the cap is intact but can be removed by tearing the aforementioned strip. In one modification, a well is formed in the center of the cap.

Abstract: A lid is rotatable relative to the upper end of a container. The container carries at least two circumferentially spaced ribs tapered longitudinally in thickness from a relatively narrow rib end to a relatively wide rib end in a given circumferential direction. The lid may have an equal number of lugs, each defining a tapered passageway having a relatively wide end sufficiently large to provide clearance around the relatively narrow end of the corresponding rib and to permit rotation of increments of successively smaller cross section past increments of successively larger cross section of the ribs until the lugs and ribs jam against each other radially, axially and circumferentially to provide a relatively rigid structure where the ribs and lugs overlap. At least three exterior walls of the ribs simultaneously engage three interior walls of the lugs when the ribs and the lugs simultaneously engage. At least one of the jamming surfaces and an engaged surface is in an oblique plane.

Abstract: A container and closure assembly for storing fluids under pressure has cooperating screw threads on the neck of the container and the closure. Mutually engageable elements on the neck and closure block the rotation of the closure in the unscrewing direction beyond an intermediate position when the closure is under pressure. The neck of the container and the closure are constructed to provide a vent for releasing this pressure to allow the closure to be fully removed.

Abstract: A closure for a container, comprising a lower closure part and a screw cap. The lower closure part has a pouring spout and can be connected with a container opening by a base element. The screw cap comprises a cap bottom and a cap shell having an interior thread. The screw cap can be screw-fastened and unfastened from the pouring spout, which is provided with an exterior thread. The screw cap is secured against being unfastened by engaged connections. The screw cap can be released for being unfastened by releasing the engaged connections. A child safety device is provided by a special design of the engaged connections between the screw cap and the lower closure part, so the body of the container is no longer a part of the child safety device and therefore can be optimally adjusted to its specific function.

Abstract: The present invention employs a plastic snap-on cap which engages both the neck crown of a container having a rectangular body and a neck having screw threads and is internally threaded to engage the neck threads of the conventional container. A foam gasket under the top of the cap prevents leakage by sealing against the neck lip. The cap has internal threads which snap over and then engage under the neck threads. Vertical "barriers" below the cap threads prevent unscrewing the cap so long as the cap skirt is intact. Score lines extend from the bottom edge of the cap skirt to above the internal cap bead which engages the neck crown and extend up to the cap threads. A tear tab is used to tear a vertical strip of the skirt which extends up between the score lines. The cap is thus tamper-evident since it cannot be removed so long as the cap is intact but can be removed by tearing the aforementioned strip. In one modification, a well is formed in the center of the cap.

The insert is screwed into the upper end of the pail. Mating locking detents are provided on the pail and on the insert so that the insert, once screwed into the pail, cannot be thereafter unscrewed from the pail. The insert allows ready withdrawal of the liquid from the pail. A child in the vicinity of a pail equipped with the aforesaid insert is protected from drowning in a liquid contained in the pail because insert prevents a child from accidentally, or intentionally, inserting his or her head into the pail.

Abstract: A removal resistant closure and container assembly is provided. The container defines an opening. The closure is applied to the container to occlude the opening. A first thread is defined by the container and extends at least partially around the opening from a leading end to a trailing end. A second thread is defined by the closure and extends at least partially around the closure form a leading end to a trailing end. A projection is defined adjacent one of the first and second threads. The projection and the one thread define a space between them which is less than the width of the other of the threads. Either the projection or the other thread, or both, are resilient to accommodate deformation during relative rotational movement of the container and closure. When the closure and container are screwed together, the threads are relatively axially displaced from a threadingly engaged condition to a disengaged condition which resists re-engagement.

Abstract: A mating closure and finish system particularly adapted for use with containers, e.g. bottles containing carbonated beverages which generate gas in the bottle headspace and where the bottle finish incorporates at least two equally spaced helical cam tracks. The closure is comprised of plural sets of cam followers which fit into the cam tracks and where the cooperation between the cam tracks and cam followers produces an axial movement of the closure as it is rotated on the finish. For a two track system, which is the preferred embodiment, each track starts 180.degree. from each other and makes at least one full turn around the circumference of the finish. Also included are intervening stops and tapered speed bumps that contact and impede the cam follower(s) in the cam tracks during closure removal to effect a delay. Raised thread segments which define the cam tracks are intersected by a plurality of vertical venting slots or pathways along their helical length to vent headspace gas.

Abstract: A container neck (14) and a container closure comprises a first thread (15) on one of the neck and the closure, a complementary second thread on the other of the neck and the closure such that the closure is moveable from fully disengaged from the neck to fully closed by turning the closure relative to the neck by less than 360.degree., at least one stop formation (17,18) carried by said one of the neck (14) and the closure, and stop means on said other of the neck and the closure engageable with the stop formation or at least one of the stop formations to hold the closure in a closed position on the neck.

Abstract: First and second engaging projected portions are formed on opposing circumferential surfaces of a tubular casing and a hollow lead portion which are rotated relative to each other so as to be coupled with, thereby spirally engaging external and internal threads formed on the respective opposing circumferential surfaces. A forward side face of the first engaging projected portion with respect to a spiral rotating direction is formed into a slanting face so as to allow the second engaging projected portion to move over the first engaging projected portion when the casing and the lead portion are completely coupled with each other. Further, backward side faces of the first and second engaging projected portions are formed into upright faces, such that the second engaging projected portion cannot move over the first engaging projected portion in an opposite direction once moving over the same. This arrangement reliably prevents the spiral engagement of the casing and the lead portion from loosening.

Abstract: A package suitable for storing and dispensing potentially dangerous material, which is resistant to opening by children yet readily openable by adults. The package is preferably a bottle which has a body and a finish portion. The finish portion has a threaded outer end for mating with a closure. A resiliently deformable cantilevered beam is connected to the finish portion between the threaded outer end and the body of the bottle. The beam is angled outward and downward from the finish portion. The beam has a substantially vertical locking surface and a pushtab spaced along the beam. The angle of the beam is such that the pushtab may be depressed substantially radially toward the finish portion. The locking surface is located between the finish portion and the pushtab so that depression of the pushtab results in a greater beam deflection and lower deflection force at the pushtab than at the locking surface. A bottle closure has threads for rotatably securing the closure to the finish portion of the bottle.
