Abstract: The utilitarian function of the engagement features on a lidded vessel is at least partially camouflaged so that the engagement features' utilitarian function is less apparent to the consumer after the lid is removed. The lidded vessel may be, for example, a lidded drinking glass—such as a lidded wine glass, beer glass, whiskey tumbler or soda glass—that is sold pre-filled and sealed with the wine, beer, whiskey or soda already inside. The camouflaging may be accomplished using one or more camouflaging techniques, some or all of them involving the presence of non-engagement elements.

Abstract: A storage and drinking container for pressurized beverages includes a drinking vessel 1 having a lip 3 and a lid formed from a cap 5 and retaining ring 12. The cap 5 seals with a surface 4 on the inside neck of the vessel and is retained in place by fingers 8 engaging under a lip 3. The fingers 8 are retained in position by a retaining ring 12. Cooperating sets of cammed surfaces 10 and 13 on cap 5 and ring 12 act on rotation of the ring to axially separate the ring 12 from the cap 5, releasing the fingers 8 from under the lip 3 and permitting the lid to be removed. A drinking vessel with a wide neck can be reliably sealed without the necessity to provide screw threads on the outer surface of the vessel 1.

Abstract: This invention provides a bottle that allows for easy and efficient application of shrink sleeves. The ease of application is partly a result of the invention's wall thickness along its body-forming portion. The body-forming portion of the invention has thick walls and thus exhibits negligible expansion during a hot-filling process. This permits a shrink sleeve to be placed onto the body-forming portion of the resistant bottle prior to filling. If the resistant bottle is hot-filled, the sleeve shrinks as a result of radiant heat emanating outwardly from the high temperature product, without the aid of an external heat source, such as a heat tunnel.

An important feature of the present invention is that the cap frictionally engages a top portion of the spout. No screw threads or similar securing means are required to retain the cap on the spout.

Abstract: A cap with a tamper-evident ring is designed to snap engage a container that is provided with an upper and lower bead. A ring of teeth provided along an inside skirt of the cap engage teeth located along an inside wall of the container. When the cap is snapped onto the container, both sets of teeth automatically engage and a plug seal provided on the cap engages the container upper bead. By turning the cap clockwise or counterclockwise, the side angles of the teeth force the cap to disengage upwards over the upper bead and unsnap from the container. When the closure is opened for the first time, the ring breaks away from the cap and slides down the container below the lower bead, which keeps the ring from coming off the container and provides evidence that the cap had been opened.

Abstract: A cap for sealing a container having a threaded spout. The cap is arranged so that it can be snapped onto and off the spout and so that it can also be screwed on and off the spout.

Abstract: A closure for a container for holding contents therein generally comprises a surface for gripping the closure in order to twist it in either direction to open it. The closure has downwardly projecting teeth on its underside; the container has upwardly projecting teeth, which mate with the downwardly projecting teeth of the closure. An outer ring on the closure circumscribes and holds in place the upper lip of the container in the closed position. Twisting of the closure in either direction causes the closure to be released from the container.

Abstract: A simple structure for a container closure system that allows for ease in closure and removal of a cap from the container is disclosed. The container closure comprises a cap having a skirt of substantially rectangular cross-section. Disposed in a central location on each of the internal surfaces of the skirt are rim-engaging members that are substantially coplanar. The container has a neck portion terminating in an outer peripheral rim surrounding an oval-shaped opening in one end of the container through which the container contents may be dispensed. Cap-engaging portions on the outer portion of the peripheral rim engage with the rim-engaging members disposed on the skirt internal surface when the cap is in a closed position over the container opening. The rim-engaging members of the present invention can be in the form of small ridges or grooves and can engage with cap-engaging portions formed by small ribs.

Abstract: An insert (1) for a closure provides, in a single component, a gasket function between the end panel (12) of the closure and the end sealing surface (22) of a container neck finish (20), a thread forming feature (3) and a tamper evident band (5). The sealing portion (gasket (2) and thread forming feature (3)) of the insert is formed from soft pliant material so as to provide excellent sealing. The tamper evident band (5) is made from much stiffer material than that of the sealing portion, thereby providing rigidity to the entire component. During assembly the integral tamper evident band (5) thus maintains the insert in a circular and non-twisted shape, ensuring ease of handling of the insert.
