Abstract: A safety cap assembly for bottles is of the type which permits unscrewing only when the cap is axially depressed and rotated to unscrew it, thereby disengaging a locking mechanism from a container thread abutment. This "push to turn" requirement makes the cap difficult for a child to remove. When the cap is rotated to unscrew it, a tamper film is marked or scored which mark is clearly visible through a clear area of the cap or through an aperture to indicate tampering. In addition, the locking mechanism is arranged to permit removal of elements which render the locking mechanism inoperative. This permits the cap to be used in a normal manner by persons that may have arthritis or other crippling diseases. Further, the cap may be utilized as a tamper indicating means alone without the child resistant feature for edible foodstuffs and liquids.

Abstract: A safety closure of the type having a unitary construction with a closed top from which an interiorly threaded skirt depends and a container having an exteriorly threaded neck on which the closure is mounted in sealing relationship. The safety closure has at least one locking member formed integrally therewith which is movable under the action of actuating apparatus between a non-locking position and a locking position in which the locking members engage appropriate corresponding locking elements provided on the neck of the container. The actuating apparatus is constituted by the top of the closure which has a dish-like configuration formed such that the application of a sufficient finger pressure on the top will result in the movement of the locking members from the locking to the non-locking position.

Abstract: This bottle has a projection or "latch" from its neck, just below the thread, and along and near the lower end of that thread. There is a gap in the cap thread, that lines up with the "latch" when the cap is fully screwed on. The cap deforms when screwed on, passing the "latch" over the end of the cap thread and into the gap. The "latch" then resists cap removal. Only torque beyond the ability of a small child (or even requiring use of a tool) frees the cap. A second projection from the neck, a "flag", is breakable. It is below the bottom end of the neck thread, just above (measured along the thread) the "latch". The "flag" can fold against the neck, but springs out if released. It catches in the cap-thread gap when the cap is unscrewed, and is torn off or broken by forcible removal of the cap. Its removal or breakage evidences that the bottle has been opened.

Abstract: The invention is directed to a threaded closure for a fuel tank and includes a thread formed on a fuel inlet stub of the tank.

At least one set of threads 3a of the stakes must be brought into mesh with the outer threads by axial pressure when the stake passes a clearance (6) and a stop is provided at the bottom of a clearance at the closed position to reverse the thrust of the axial pressure to demesh the threads and prevent turning.

Abstract: A child resistant container and cap assembly requiring simultaneous tilting of a lock element in the form of a ring relative to a cap and rotation of the cap relative to the container to disengage complementary lock elements on the ring and container to permit disengagement of threads normally holding the cap in sealed relationship on the neck of a container.

Abstract: The invention contemplates safety-closure structure involving threaded engagement of cap and bottle-neck members, wherein coacting lug formations on the respective members have compliantly yieldable cammed latching engagement in approach to a fully-closed relation of the members and wherein, once in the fully-closed relation, a positive-lock relation prevents unthreading rotation of the members. The engaged threads are sized for a quantum of axial lost-motion, and resilient action of a seal which reacts axially between the members is operative to constantly load the cap member to its axially upper limit of the lost motion. The lug formations are of such axially limited extent that, when the members are in their fully-closed relation, an axial depression of the cap member through the lost motion and against the resilient seal action is necessary to free the positive-lock relation of the lugs formations, thus then permitting a thread-off rotary manipulation of the cap member.

Abstract: A tamper-proof closure for a container including an endwall and an annular, threaded sidewall. The sidewall includes an internal projection for mating with a part of the container to prevent turning of the closure when the closure is mounted on said container. A tear tab is provided on the sidewall radially outwardly of the projection. The sidewall includes tear facilitating portions on circumferentially opposite sides of the tear tab to enhance tearing of the sidewall on opposite sides of the tear tab to permit the tear tab and the projection to be swung outwardly to a removed position in which the closure can be turned. Another aspect of the invention includes a method of making the closure.

Abstract: The invention contemplates a safety closure cap having axially compliant connection between two concentric parts, the inner of which has rotatable connection to a bottle neck or the like. The outer concentric part has ratcheting one-way engagement with coacting ratchet means on the bottle, the engaging direction being such as to oppose disengagement of the rotatable connection. Only by performing the extra operation of axially lifting the outer part of the cap, against the stiffness of the compliant connection, can the ratchet engagement be dislodged, to the extent permitting rotated disengagement of the bottle closure.

Abstract: 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.
