A child resistant closure and container having a lid base recess. A closure includes an annular inner member defining an opening, the inner member having a camming recess. The closure also includes an outer member engageable with the inner member, the outer member including a lid base, a lid hingably connected to the lid base, and an annular guard ring surrounding the lid and lid base. The annular guard ring is frangibly connected to at least one of the lid and lid base, preferably along a frangible line formed by a plurality of bridges. The outer member can be formed integrally as one piece. When the inner member and outer member are joined, the guard ring preferably separates from the lid and lid base, and the lid base is at least partially retained within the camming recess. Once separated from the lid and lid base, the guard ring is movable between a guarding position in which it obstructs access to the lid, and a revealing position in which the lid can be rotated or lifted upward, away from the opening.

The closure has moveable panels on the side wall which, when depressed, allow the unscrewing of the closure from the neck of the jar or vial. The moveable panels include tabs engaging stationary locking lugs on the neck finish annulus, which prevent removal of the closure without depressing the tabs. The annulus and stationary locking lugs can be an integral part of the jar or vial.

Child-resistant one-piece container and one-piece closure assembly

Combined container and child-resistant closure

A threaded closure is provided with a snap-fit ring. A snap-fit tamper-evident band with three concentric portions is provided such that the first portion engages the closure's snap-fit ring and is removed from the rest of the band when the closure is rotated off of the container neck. A second portion includes tabs for engaging, e.g., an annular ring on a container neck. A third portion remains on the container neck when the first portion and the cap are rotated off. A number of frangible posts are also provided for connecting the first portion to the second and third portions.

Snap-band tamper evident

A tamper-evident closure for sealing an open-topped container. The closure is of one-piece molded construction and includes a cap having an annular top wall and an annular skirt dependent therefrom and joined thereto about the periphery of the top wall. The skirt has an internal thread for cooperation with the thread on the finish of the container. The closure further includes a tamper-indicating assembly including a band spaced from the skirt by a number of frangible bridges. The assembly also includes a segmented ring connected to the bottom of the band and extending upwardly and inwardly therefrom with the ring including a number of segments with adjacent segments being separated by a slot. The assembly also includes a number of resilient tabs connected to the upper end of each segment and extending upwardly and inwardly therefrom for engaging the breaker ledge of the container finish upon attempted removal of the closure from the container.

Tamper-evident closure

A child-resistant, tamper-evident closure having nested inner and outer caps with ratchet teeth on the interfacing skirt walls of the respective caps to cooperate to fasten the closure onto the container, and ratchet teeth on the interfacing top walls of the respective caps for removal of the closure upon simultaneous application of torque and a downward force. The inner cap further includes a tamper-indicating ring depending from the lower edge of its skirt, the ring including a breakable connection for detachably securing the lower portion thereof to the inner cap skirt. A plurality of tabs extending upwardly and radially inwardly from the ring engage an annular shoulder on the container during the removal of the closure to break the ring away from the inner cap skirt.

Tamper-evident child-resistant closure

A tamper-evident closure is provided which includes a threaded cap and tamper-indicating means having upwardly and inwardly folded tabs which lock against the lower surface of an annular shoulder on a container neck to retain the tamper-indicating means on the neck as the cap is removed. The tamper-indicating means includes a ring to which the tabs are integrally connected at their lower outer ends. The tabs are resilient and are flexed by the container finish at the joints where they are joined to the ring. The closure of the present invention may be installed simply by screwing it onto a container neck in a one-step process. The flexible tabs assist in guiding the closure and centering it as it is lowered onto the container neck for installing and do not require the holding of the closure or the container finish to close tolerances in order to be consistently effective. The method of manufacturing the closure of the present invention includes the steps of molding a plastic blank which includes a cap, a ring, and tabs extending vertically downwardly from the ring; bending the tabs radially inward and upward; and heating the folded joints formed where the tabs are bent upward from the ring to set the tabs in their upwardly and inwardly inclined positions.

Method of manufacturing a tamper evident closure

A child-resistent, moisture-tight safety closure having an end wall with an annular depending skirt, the skirt having a plurality of locking lugs disposed on the inside thereof. The locking lugs cooperate with retaining notches adjacent to the open mouth of an associated container to releasably retain the closure on the container. A sealing plug integral with the end wall of the closure and concentric with the annular skirt effects a moisture-tight seal with the inner wall of the container. A plurality of resilient members are integral with the interior of the closure at the junction of the top wall and the skirt, the resilient members extending downwardly and inwardly so as to engage the end surface of the container opening. The compression of the resilient members serves to bias the locking lugs on the closure into locking relationship with the retaining notches on the container with a force sufficient to ensure the child-resistant characteristics of the closure.

One-piece moisture-tight safety closure and container

A moisture proof vial and closure system are provided which may be used in a child-resistant mode or in a non-child resistant mode. In the child-resistant mode locking lugs 22 on the closure are interlocked with bayonnet slots on the vial. A non-child resistant operation in a moisture proof system may be achieved by providing an integral sealing plug 21 extending from the top of the closure and by adding a detenting means 51 inside of the container to engage and hold the sealing plug 21 against sliding outwardly of the container. A simple push inward will force the sealing plug 21 home to its sealing position to seal the medicine in the vial, and a simple push or pull on the closure to force the fitment from the detenting means is needed to remove the closure. The preferred detenting means 51, 15 is in the form of radially inwardly directed projections 52 formed on the interior container wall to abut and restrain the sealing plug against inadvertent sliding from the container. For the child-resistant mode, the sealing bead 50 on closure 10 is carried on sealing plug 39 which is formed on a discrete and separable fitment 40, while in the non-child resistant mode, the sealing plug 21 is integral with the top wall 18 of the closure.

Moisture tight closure and container

A moisture proof vial and closure system are provided which may be used in a child-resistant mode or in a non-child resistant mode. In the child resistant mode locking lugs 22 on the closure are interlocked with bayonnet slots on the vial. A non-child resistant operation in a moisture proof system may be achieved by leaving the locking lugs 22 off of the closure skirt wall 20 and by adding a detenting means 51 inside of the container to engage and hold a sealing plug 39 against sliding outwardly of the container because of the lack of locking lugs on the closure 10A. A simple push inward will force the sealing plug 39 home to its sealing position to seal the medicine in the vial, and a simple pull on the closure to pull the fitment from the detenting means is needed to remove the closure. The preferred detenting means 51 is in the form of radially inwardly directed projections 52 formed on the interior container wall to abut and restrain the sealing plug against inadvertent sliding from the container. The sealing bead 50 on closure 10B is carried on sealing plug 39 which is formed on a discrete and separable fitment 40. For the closure 10A, the sealing plug 39 is integral with the top wall 18 of the closure.
