A hinged dispensing closure of unitary molded construction is disclosed which may be readily opened by an adult using one hand. A narrow slot of short length is molded near the periphery of the top wall of the snap-hinged cover cap opposite its hinged connection to the main closure. The sidewall of the cover cap includes axially extending parallel score lines from near its skirt edge to the ends of the slot to define a tab. Pressing by the thumb on the tab while holding the package in the same hand ruptures the scores and deflects the tab inwardly for ready access to an exposed edge of the formed slot; and pressure on the edge opens the cover cap. The deflected tab is held by an internal cam wall inwardly of the slot, which indicates that the package is opened when the tab is held in this deflected position. A second embodiment provides a hook and latch locking means between the main closure and cover cap opposite the hinge. This lock may be disengaged by the thumb for unlatching the cover cap by depressing its skirt wall at the hook and latch location and opening the cover cap with one hand. The main closure is threaded on the container. The main closure and container are provided with cooperating ratchet teeth to render the closure on the container a safety closure against accidental removal by children.

A non-reusable tamper indicating package comprising a container and a closure. The container has a body portion and a neck portion defining an opening and having an annular bead spaced from the end of the neck. The closure has a top wall and a peripheral skirt and a retention and holding bead on the skirt adapted to engage the annular bead on the container. The closure includes spaced score lines on the skirt and a portion of the top wall defining a severable portion of the skirt between the score lines such that when the severable portion is pulled outwardly and upwardly, the closure is severed along the score lines. A foil sheet having a layer of thermoplastic material on each surface thereof and is thermally bonded to the upper end of the container. A liner ring overlies the foil sheet and is thermally bonded to the thermoplastic material on the foil. The top wall has a depending portion thermally bonded to the thermoplastic material on the foil sheet such that when the severable portion of the skirt and top wall are severed along the score lines, the depending portion of the closure tears the foil sheet to provide access to the contents and the foil sheet can not be reused and the closure can not be reused to reseal a container.

Tamper indicating, non-resealable closure

The disclosure relates to a unitary molded article and a method for producing a multi-part closure for assembly on the neck of a container, the closure involving an axially shiftable valve element which is movable between open and closed position. All parts of the multi-part valve element are integrally molded in a common molding cavity and the various relatively movable parts are interconnected by thin annular webs which are severed and the parts placed in proper operative condition during the assembly of the closure to the neck of a container by a conventional applicating machine.

A child-resistant package comprising a container having a neck with threads thereon and a child-resistant closure. The closure comprises a cap made of organic plastic material and having a top wall and a peripheral skirt, having threads thereon adapted to engage the threads of the container. The skirt has a radial flange and a plurality of circumferentially spaced depressions on the upper surface of the radial flange. The closure also comprises a ring telescoped over the cap and surrounding the skirt of the cap. The ring has a plurality of lugs extending upwardly from the radial flange of the cap and adapted to engage the depressions upon application of a downward force on the ring. Each depression on the radial flange has a substantially vertical surface at one circumferential end adapted to be engaged by a lug on the ring when the ring is rotated in a direction to thread the closure onto the container. Each depression on the radial flange of the closure also has an inclined surface at the other circumferential end such that upon mere rotation of the ring in a direction to unthread the closure from the container results in the lugs on the ring sliding up the inclined surfaces so that the closure can only be removed by a combined downward force on the ring and rotational force in the direction of threading the closure off of the container.

Child-resistant package

A child-resistant closure assembly is disclosed which includes inner and outer cap members in a nested configuration. Leaf spring and ratchet elements are respectively provided on the cap members whereby torque can normally be transmitted from the outer cap member to the inner cap member only in the closure tightening direction. For transmission of torque in the closure removal direction, drive lugs on the inner cap member are engageable in non-concentric apertures formed in the panel of the outer cap member. The drive lugs and apertures are normally maintained axially out of engagement by the leaf springs formed on one of the cap members. When the leaf springs and ratchet elements are transmitting closure tightening torque, the non-concentric apertures are angularly displaced relative to the drive lugs. The apertures may be visually aligned with the driving lugs by reverse rotation of the outer cap and then the outer cap is axially shifted to engage the driving lugs in the apertures for removal of the closure assembly.

Child-resistant closure assembly

A child-resistant closure includes a tamper-proof band which engages an associated container finish, and which must be separated from the remainder of the closure for removal of the closure from the finish. A pull tab and weakening grooves are provided to permit manual separation of the tamper-proof band from the remainder of the closure. A resilient shield integrally formed with the tamper-proof band overlies the pull tab and normally prevents grasping thereof. Removal of the closure is possible only when the shield is manually deflected and held in position while the pull tab is grasped and the tamper-proof band torn away from the remainder of the closure.

Closure with child-resistant tamper-proof band

A tamperproof press-on, snap cap for closing a container having a neck defining the mouth opening. The container has an upper cap retaining bead and lower, enlarged annular ledge. The snap cap includes an enlarged end wall and a downwardly depending skirt inwardly of the end wall periphery which has an inwardly directed radial annular bead for cap retaining engagement with the container bead. A cylindrical tear sleeve depends downwardly from the peripheral edge of the end wall of the cap, is spaced radially outwardly from the skirt, is longer than the skirt and sized for encircling and snugly engaging the annular ledge. The tear sleeve has a peripherally weakened annular tear zone at the cap end wall juncture and includes an axial tear groove extending from the weakened tear zone to the lowered edge of the sleeve. Adjacent the tear groove is shortened section to enable grasping and tearing the sleeve. Two alternative forms of cap end wall are shown, the first a solid end wall providing a one-piece cap, the second, an apertured end wall useable with a two-piece closure wherein an underlying lid seals off the mouth of the container and is held by the overlying cap.

Closure

A child-resistant, safety closure for a container having a dispensing end including a threaded neck portion onto which the closure is adapted to be threadably assembled. The closure is of the type having an annular sidewall section having a flexible distal end portion provided with at least one interlocking member adapted to interlockingly engage at least one complementary interlocking member on the dispensing end of the container in such manner that interlocking engagement is achieved when the closure is in a fully closed position on the container neck portion. Removal of the closure requires manual compression of the sidewall at locations straddling the interlocking members coupled with concurrent retrogressive turning movement of the closure. An additive safety feature embodies providing a secondary interlocking engagement when the closure is partially removed. Thus, such manual manipulation ordinarily must be repeated at each successive interlocking position of the closure and is both beyond the ordinary capability of a child or other person of similar mental capabilities. The closure features a frictionally slidable, fluid-tight sealing arrangement which in one aspect is operative to prevent leakage of the container's contents when the closure is in a fully closed position, and which in another alternative aspect is operative to prevent such leakage at and between both the fully closed and the succeeding partially removed interlocking locations of the closure on the container dispensing end.

Child-resistant safety closure

An improved home canning closure system is provided for a home canning jar featuring a plastic ring and a metal lid combination which is adapted to allow excess pressure to escape while preventing the escape of the contents from the container. The plastic ring includes an annular top panel portion and a skirt portion depending downwardly from the outer periphery of the top panel portion. The skirt portion incorporates buttress threads on its inner surface to engage threads on the external neck of the home canning jar. The plastic ring features an upwardly and outwardly inclined ramp portion on its lower surface and a thin section at the junction of the top panel and skirt portions which combine to form a spring member to maintain a constant force to bias the metal lid into sealing engagement with the upper rim on the home canning jar.

Home canning system

A linerless closure for a container having a neck portion terminating at its end in an annular rim defining the periphery of an open mouth, the closure including a top panel with a depending cylindrical skirt adapted to engage the neck of the container. A downwardly and outwardly depending annular sealing fin is provided on the inside of the top panel of the closure and is adapted to engage the annular rim of the container to close and seal the open mouth of the container. An annular wedge or stop member depends downwardly from the inside of the top panel at a location radially outwardly from the annular sealing fin and has and inwardly inclined lower surface adapted to bias or wedge the sealing fin into firm engagement with the annular rim of the container.

Linerless closure

This disclosure relates to a tamper-indicating press-on, pull-off closure for maintaning pressure in a container whereby the closure and container provide a package which may be readily opened by a consumer without the use of tools and without the creation of dangerous sharp edges. This closure includes a cap and a unique cap liner which fits within the cap and is formed integral with a pull ring for removal of the cap from a container. A plurality of severable tamper-indicating webs are formed between the pull ring and the cap liner and sever upon actuation of the ring pull to indicate tampering with the package. The cap incorporates a plurality of scores in its skirt portion which fracture when the pull ring is actuated to thereby release the cap from engagement with the container.

Easy-open, tamper-indicating closure

A child-resistant liquid seal closure and container combination featuring one or more camming projections on the container neck and one or more locking lugs on the interior surface of the closure which engage the camming projections to prevent rotational removal of the closure from the container. The closure may be removed from the container only by squeezing the closure on opposite sides to force the locking lugs radially outwardly beyond the camming projections to permit rotation of the closure relative to the container. The camming projections on the container neck are of sufficient axial height to prevent rotation of the closure relative to the container both when the closure is fully tightened onto the container and when the closure has been rotated 180.degree. relative to the container, thereby necessitating two separate squeezing actions to remove the closure from the container. The closure of this invention has an outwardly tapered skirt which, when threadingly engaged on a straight cylindrical neck, provides sufficient space and resiliance to allow for squeezing of the closure to disengage the locking lugs from the camming projections.
