Abstract:
A child resistant package including a container having an open end and multiple threads on the external surface of the container adjacent the upper end. A closure having a base wall and a peripheral skirt has an inner surface formed with multiple threads corresponding in number to the multiple threads on the container for engaging the threads on the container. A release element formed integrally on the exterior surface of the container below the threads. The release element includes an integral axial lug extending upwardly toward the open end of the container. The closure has a plurality of circumferentially spaced stops on the inner surface of the skirt of the closure below the threads corresponding in number to the threads on the closure and the number of threads on the container. The lug on the release element normally extends upwardly for engagement with at least one of the stops such that when the release element is pressed radially inwardly, the lug is disengaged from engagement with a stop and the closure can be removed by unthreading the closure from the container.
Abstract:
A squeeze and turn child resistant package including a container having a finish and a closure having a base wall and an outer peripheral flexible wall depending from the base wall. The wall has an internal thread on the inner surface thereof, the finish has an external thread thereon. The closure has an internal surface with spaced flexible chordal lugs extending circumferentially in the direction of removal of the closure. The container finish has opposed radially extending abutments. Each abutment includes a radial abutting surface. The finish of the container includes an integral radial projection adjacent the radial abutting surface of the abutment which has a lesser radial extent than the abutment. The radial projection has a chordal surface extending to the intersection of the radial abutting surface on he finish such that the chordal lug on the closure is forced toward the intersection when a closure is rotated in a retrograde direction to remove the closure without flexing the peripheral wall. The finish has stops below the threads engaging a blunt end leading end of the thread on the closure to limit the movement of the closure and orient the closure.
Abstract:
A child-resistant package comprising a container having an exteriorly threaded finish portion, and a closure comprising an inner cap member having a top panel integrally formed with a depending skirt portion having threads formed on the interior surface thereof for engagement with the finish portion of the container, and an outer member having a peripheral skirt portion surrounding the skirt portion of the inner cap member. Interengaging members between the inner cap member and the outer closure member are operable upon relative axial movement between the members to interengage the members such that rotation of the outer member will also rotate the inner member to disengage the threads of the inner member from the threads of the container. A tamper-indicating member comprising an annular ring has portions extending between the lower edge of the skirt portion of the outer closure member and a portion of the container which are operable to prevent axial movement of the outer closure member relative to the inner closure member.
Abstract:
A child resistant closure and container comprising a container, a finish fitment rotatably mounted on the open end of the container, and a closure having a top wall and a skirt. Threads between the finish fitment and the skirt require relative rotation to disengage the closure from the finish fitment. The finish fitment includes a top portion interposed between the top wall of the closure and the container such that the top wall of the container engages the top portion of the finish fitment. The fitment and the closure are rotatable relative to said container and said threads are disengageable only when said fitment is manually grasped and prevented from rotating relative to the container. The container includes projections that engage notches in the fitment to prevent rotation of the fitment during threading of the closure so that the fitment need not be held manually during the application of the closure.
Abstract:
A method of constructing a lined closure in which a liner having a circular base, a liner membrane and a thermoplastic adhesive securing the liner membrane to the base, is press fitted into a closure having a skirt with internal threads such that the liner engages and rides over the threads and is positioned against the internal base of the closure. Heat is applied to the liner at least around the periphery of the liner so as to melt the thermoplastic adhesive and resecure the liner membrane to the liner base. In this way, the liner membrane is resecured to the liner base so as to correct any separation between the membrane and base that might have occurred as the liner was press fitted into the closure.
Abstract:
A child resistant reminder closure comprising an outer closure member having a base wall and a peripheral skirt, an inner closure member having a base wall and a peripheral skirt with a bead on the outer closure member retaining the inner closure member against limited axial outward movement relative to the outer closure member. An assembly of a day disk and an indexing disk is provided in the outer closure member and is rotatable relative thereto. A first set of flexible radial ratcheting fingers extend radially from the day disk and engage radial lugs on the undersurface of the base wall of the outer closure member. A second set of flexible radial ratcheting fingers extend radially from the day disk and engage circumferentially spaced lugs on the upper surface of the indexing disk. Axially interengageable lugs and recesses are provided on the outer closure member and the indexing disk and interengaging lugs and recesses are provided between the indexing disk and the inner closure member which are interengaged to remove the closure or to apply the closure to a container thereby providing a child resistant feature. A window is provided on the outer closure member and is associated with indicia on the day disk to indicate the circumferential position of the outer closure member relative to the day disk.
Abstract:
A child resistant closure comprising outer and inner nested closure members each of which has a base wall and a peripheral skirt with sets of lugs on the inner surface of the outer base wall and the outer surface of the inner base wall adapted to engage each other when the outer closure is rotated for application to a container, but slip or cam past each other on inclined surfaces when the outer closure is rotated for removal. At least one integral spring finger extends from one base wall toward the other base wall such that the outer closure member is held out of engagement with the inner closure member. To remove the closure, the outer closure member must be pressed downward, while simultaneously being rotated. The camming action of the lugs is then resisted by a frictional engagement of corners of the lugs on the outer closure with inclined surfaces on the lugs on the inner closure.
Abstract:
A tamper-indicating package that includes a blown glass container or blow molded plastic container, and a molded thermoplastic closure that is affixed to the finish portion of such container. The finish portion of the container has a radially outwardly projecting bead at the bottom portion of such finish portion. The closure has a flexible tab that originally extends outwardly and downwardly from the top of a notch in the skirt of the closure, and is foldable through the notch in the skirt of the closure to engage the underside of the bead in the finish of the container. The closure tab is attached to the closure skirt by a frangible connection, and separates from the closure skirt by the fracture of such frangible portion during the removal of the closure from the container, since the tab is prevented by its engagement with the container bead from being removed with the other elements of the closure.
Abstract:
Five embodiments of a tamper indicating molded plastic band that locks over a ledge on the closure and beneath a flange on the container. The cylindrical band is molded with continuous locking rings or interrupted tabs joined adjacent the top end bottom edge thereof and which extend inwardly and generally toward each other to form mechanical locking members. Depending upon the particular arrangement of the locking rings on the tamper indicating band, the band would be applied to the closure before or after threaded application to the container. The band may be used with a plastic or metal closure and with a plastic, metal or glass container having a threaded neck and outwardly extending radial flange therebelow beneath which the ring or tab will lock.
Abstract:
A child resistant package comprising a container and a closure. The container has an open end, a thread on the inner surface of the open end, diametrically opposed lugs on the outer surface of the open end having a radially extending surface. The closure has a top wall, a peripheral skirt and an annular wall spaced radially inwardly from the peripheral skirt, and having an external thread on the outer surface thereof interengaging the thread on the inner surface of the upper end of the closure. The skirt has radially engageable lugs extending radially inwardly from the skirt. The skirt is flexible such that the closure can be engaged with the container by interengagement of the threads and rotation of the closure in one direction until the lugs on the skirt engage the lugs on the container and the closure may be removed by radially compressing portions of the closure at about 90.degree. between the lugs on the closure to disengage the lugs on the closure from the lugs on the container such that the closure can be removed by rotation relative to the container in the opposite direction.
