Abstract: A fuel additive bottle has a neck and thread pattern that allows insertion into a capless fuel system so the bottle's contents can be poured by gravity into a fuel tank. The neck of the bottle is elongated and has a diameter of approximately 0.854?, and the novel thread pattern includes thread interruptions that form at least one threadless path. In use, the spring loaded tabs of a capless fuel system are depressed by the threadless path portion of bottle, thereby triggering the self-sealing mechanism to open, so the fluid receiving aperture is exposed. The use of the threadless paths facilitates the safe and easy entry and removal of the bottle from the capless fuel system.

Abstract: A stackable container, including a body and a cap threadingly engageable with a neck portion of the body and having a vaulted interior and a top portion formed with a frustrum-shaped depression for snap-registered engagement with a base portion of a counterpart of the body, the cap further including handle projections and a skirt. Opposite stop structures prevent rotation of the cap relative to the body beyond predetermined threaded engagement; a detent releasably captures the body in the predetermined threaded engagement. A base portion of the body having inclined side walls facilitates rotation of the body with respect to the cap. The skirt guides the body into alignment with the cap. The base can have four of the side walls forming a square, the containers of a stack having any of four relative orientations. A consumable product such as a cosmetic can extend into the cap from the body.

Abstract: A screw closure (10) has a screw cap (1) and a tamperproof band (5). The screw cap (1) has a head plate (2) with a cylindrical lateral cap surface (3,provided with an internal thread (4) and wherein the tamperproof band (5) has a flexible band (6) and is connected to the lower periphery of the lateral cap surface (3) via one or more easy-tear elements (7). In order to create a screw closure which has a flexible band and, even with relatively large tolerance deviations between the closure and container neck, still ensures that the tamperproof band can be reliably torn off is thus providing enhanced functional reliability. The flexible band (6) is a continuously encircling flexible band which, distributed over its circumference, has portions (8) which can be extended easily and, therebetween, portions (9) which are less easy to extend.

Abstract: A plastic closure is disclosed which is configured for enhanced performance and reduced closure weight. Notably, the closure includes a compound, internal helical thread formation including an upper retention portion which provides desired closure hoop strength and sealing performance, and a lower guide portion which is configured for light weight while functioning to guide the closure onto an associated container during application. The closure can further include a stepped top wall portion having a relatively thick outer region, and a relatively thin central region. A tamper-evident band of the closure can be configured to include a deformable free edge portion for enhanced tamper-resistance.

Abstract: The invention relates to a screw cap (10) capable of being screwed onto the neck (44) of a container body (40), the screw cap comprising a substantially cylindrical screw section (17) comprising a screw thread (16) on its inner face, at least one tamper evidence member (18) for indicating an initial opening of the screw cap (10), and a desiccant chamber (24) located radially inwardly to the screw section, wherein the screw section (17) is radially resilient.

Abstract: A safety closure including a top wall having a first diameter, an outer cylindrical shell depending downwardly from the top wall first diameter, an inner cylindrical shell depending downwardly from a second diameter of the top wall, and a retaining flange projecting inwardly and downwardly from a lower edge of said inner shell opposite said top wall. The inner shell second diameter is less than the top wall outer diameter, and the inner shell is coaxial with the outer shell. The retaining flange is engageable with an underside surface of a locking bead provided on an external surface of the container neck, thereby maintaining a constant downwardly-directed axial force being imposed on the safety closure, which results in a constant upwardly-directed radial force being imposed on the sealing gasket by an upper terminal lip of the container neck.

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: The packing device has a cap insidely containing a cover provided with a seal corresponding to a bearing surface of the body of the packing device. The body forming lateral studs cooperates with protruding bearing surfaces formed by lugs defined by the cap.

Abstract: A dispensing closure in which the discharge passage is provided in an opening or openings in the side wall of the closure. The dispensing position of the closure is accomplished by it's elevation above the upper end of the container by a twist motion when equipped with threads to unscrew, or by a pull-up slide arrangement designed into the container and closure. It is returned by a reverse procedure to a closed and full sealing position for complete protection of the containers ingredients.

Abstract: In convention lug caps or pre-threaded caps to be screwed onto a threaded neck ring of a bottle or jar, it sometimes happens that the lugs or threads become hooked under the threads during application of the cap. This can lead to damage to the lugs or threads and failure of the closure. According to the invention, a lug cap or pre-threaded cap is provided with a formation such as a wall to prevent the cap being applied to the neck of the bottle when such hooking is threatened.

Abstract: A container closure having a skirt portion provided with an inwardly rolled, continuous, reinforcing bead on the lower edge thereof and engageable with locking projections or threads provided on the container neck portion.
