Abstract: This invention is one or more integral molded pull-up ring extended either vertically or horizontally from the top and the rim of the plastic bottle top. The end of the pull-up ring is free end and the other is the connecting end which connects to the bottle top. The free end forms a bigger and wider ring and the connecting end can be one or two. Moreover, at the connecting end, users can add one narrow space. When the pull-up ring is horizontal, users can install at both ends of the narrow space a protruding block and a withholding restrainer. When the pull-up ring becomes a perpendicular angle, it becomes easier for users to carry the container.

Abstract: This innovation is a plastic pull-up ring which is part of the bottleneck ring. As a result, the pull-up ring enables users to hold and carry containers. The narrow space at the connecting end of the pull-up ring helps the ring to turn freely. The protruding block can match with the withholding restrainer closely when it turns 90 degrees. Moreover, a push will turn the pull-up ring to a perpendicular angle so that users can carry containers or bottles easily. When users want to connect two bottleneck rings, the narrow space on the pull-up ring enables the pull-up ring to turn freely. Two blocks can block each other once they are turned 90 degrees. The continuing convex and concave parts at the free end of the pull-up ring enable the pull-up rings on both the right and left to match and form a handle bar.

Abstract: An improved, easy opening, screw-cap for threaded opening type containers is disclosed, consisting of a plastic or metal cap of generally cylindrical shape. Located along the upper section of the cap's outer circumferential surface are three, equally spaced, grasping protrusions, that extend radially outward from the radial center of the cap, so as to form a cap of a generally rounded, triangular configuration as seen from above. These grasping protrusions provide torsional, mechanical interference for the hand and it applies rotational force to screw on or off the cap. A series of vertically extending, gripping ribs, are equally spaced along the outer circumferential surface of the upper section of the cap, and are designed to make it easier to screw the cap on and off the neck of a conventional container, such as a bottle. Conventional internal screw threads are used on the internal cavity of the cap to attach the cap to the neck of a conventional container, such as a bottle.

Abstract: A lidded insulator for a beverage container comprising an insulator lid hingedly attached to an insulator body by means of a hinge. An insulator top ring having an insulator top ring bore is attached to the insulator lid. The hinge is made of resilient material possessing material memory tending to urge the hinge into a straight position. This hinge material memory tends to urge the insulator lid into a closed position. The lidded insulator for a beverage container is sized to frictionally admit a standard sized beverage container. Thus the beverage container is held securely within the insulator body, and when the insulator lid is closed on the beverage container, the frictional fit between the insulator lid and the beverage container holds the top closed, and together with the hinge material memory, urges the insulator lid top into sealing relationship with the beverage container opening.

Abstract: A bottle closing cap is disclosed that is openable merely by a finger pressure on a domed top side of the cap, whereby it is possible to provoke an expansion of a depending, axially preslit cap skirt portion of the cap. The cap can resist overpressure in the bottle because the ends of the skirt segments are stabilized against overlapping, e.g. in that at each slit (6) they are shaped with respective counterphased edges (12,14). Hereby the caps will be mountable by a fully conventional equipment and, despite being easy to open, they will resist a considerable pressure in the bottles.

Abstract: A tamper-indicating, child resistant closure for a threaded bottle includes an inner cap and an outer driver telescoped over the inner cap. The inner cap includes a top wall having spaced apart upstanding ribs. The outer driver includes a top wall having a pair of top wall segments hinged for pivotal movement to, and being spaced apart from each other by a spacing rib also forming part of the top wall of the driver. Each of the top wall segments initially is secured to contiguous sections of the outer driver by frangible, tamper-indicating tabs, and the top wall segments are moved from a generally horizontal position to a generally vertical position after the tamper-indicating tabs have been broken to form a driving section in the top wall of the driver. This driving section then is directed into the space between the upstanding ribs associated with the top wall of the inner cap by moving the inner cap and outer driver axially toward each other.

Abstract: A closure is provided for an opening to a container interior. The closure has a base for attachment to the container at the opening and defines a discharge aperture communicating with the opening. A lid is hingedly connected to the base for movement between a closed position occluding the aperture and an open position away from the aperture. A manually releasable latch is defined cooperatively by the base and lid to hold the lid closed. The lid has an outwardly projecting engaging member whereby the user can release the latch and apply a force to the member to lift the lid via the member.

Abstract: In a container cap, comprising a primary cap provided with an outlet opening in a top wall thereof, and fitted to a mouth of a container, and a secondary cap having an end hinged to the top wall of the primary cap, a slide member slidably overlies an upper surface of the primary cap, and includes a ramp projection projecting vertically therefrom and a lateral projection extending laterally therefrom, and a cover member overlies the slide member. The ramp projection is adapted to move the secondary cap vertically in an opening direction by engaging the secondary cap via the cover member while the lateral projection is adapted to engage an inner surface of the hinge to force the secondary cap in an opening direction. Because the cover member overlies the slide member, the content of the container dripping or spilled from the outlet opening is shielded from the slide member by the cover member.

Abstract: A closure for a container is provided which includes a collar engaging the opening of the container, and a removable cap pivotally hinged to the collar by means of a double-fold hinge.
