An automatic opening and closing device for a container comprises a closure flap within the container and a pivot arm with a weighted portion. When the container is in a first position, the centre of mass of the weighted portion is offset horizontally and vertically from the pivot point of the pivot arm and acts to bias the closure flap to close an opening in the container. When the container is rotated in a first direction to a second position, the weighted portion causes the pivot arm and closure flap to rotate relative to the container in a second direction opposite to the first direction, to bias the closure flap away from the opening. In the first position, the weighted portion is offset vertically by a greater distance than it is offset horizontally. A locking mechanism may also be provided, which is operable to the user to keep the container closed even when tilted.

The present invention provides an anti-theft container having a body, a first cover, a second cover, a pulling structure, and an accommodating recess. The body comprising a convex fastening portion; the first cover comprising a plurality of first coupling portions and a tab; the second cover comprising a top, a bottom, a groove portion, a plurality of second coupling portions and a tear line; the tear line enclosing a shaped area along the second cover and the pulling structure is able to be randomly disposed within the circumferential region. When the convex fastening portion is inserted to the retaining groove portion relative to each other, the convex fastening portion is disabled to be separated from the retaining groove portion, an external force is required to be applied to the pulling structure in order to lift the pulling structure along with the circumferential region so as to be separated from the second cover. When the first cover combined with a plurality of the second coupling portions of the second cover through a plurality of the first coupling portions, the tab which needs to be applied to an external force in order to lift the first cover and separated from the second cover.

A tamper-evident container including: a container body having a first hollow convex loop on a periphery of an opening thereof; and a lid having a second hollow convex loop and a force application structure, where the second hollow convex loop is used to engage with the first hollow convex loop, and a loop-shaped breakable line is provided on a loop-shaped top surface of the second hollow convex loop; where, when an illegitimate user applies a lifting force on any local area of the second hollow convex loop of the lid to make the local area moving upward with a displacement exceeding a threshold, a corresponding local area of the loop-shaped breakable line will be broken to show that the tamper-evident container has been tampered with.

A cover for a beverage can includes a circular disc, an opening within the circular disc, and a raised lip fixedly attached to a circumference of the circular disc. The cover for a beverage can is useful for providing a means for covering a beverage can when in an opened condition, so as to prevent insects and debris from entering the beverage, to prevent release of carbonated gas from the beverage and to prevent premature warming of the beverage.

Lid caps outfit lid assemblies thereby providing lid-cap combinations for beverage cans. The lid assemblies include a lid rim portion, a lid capping plate, and a can opener element and are attached to a lower can body for forming a beverage can. The lid caps include a cap plate centrally located relative to an outer cap periphery. A cap groove is configured to firstly attach the lid cap to the lid assembly by mated engagement, and may include a pivot structure for providing a can-opening access aperture and closing the can-opening access aperture. In certain embodiments, the cap plate includes a fastener-letting aperture. The can opener element is attached to the lid capping plate via a fastener as extended through the fastener-letting aperture thereby sandwiching the cap plate intermediate the can opener element and the lid capping plate for secondly attaching the lid cap to the lid assembly.

An illustrated view of an exemplary lid for protecting a top of a beverage can is presented. The lid is useful for protecting the top of the beverage can from dirt, grime and bacteria which may be inadvertently gathering on the top of the beverage can. The dirt, grim and bacteria may cause disease, illness, a distasting of a beverage of the beverage can, etc. The lid has a bottom surface and an interior side surface. The interior side surface of the is an opposite side of the side surface of the top of the lid. The interior side surface of the lid is preferably has a ribbed pattern. The bottom surface of the lid has an opener which is also used to secure the lid to the top of the beverage can.

A tamper-resistant lid assembly for dispensing a premeasured amount of liquid from a beverage container and a method of providing a tamper-resistant lid assembly for use in dispensing a premeasured amount of liquid. The assembly includes a cup and a ring that are secured to one another using a snap-fit connection, as well as a lockable connection enabled by a selectively twistable rotation of the cup and the ring once the snap-fit connection is established.

A container lid assembly including a rotational and axial guide feature extending radially from an interior surface of a lid sidewall. The rotational and axial guide feature is designed to provide axial translation and retention of a cap or other accessory when the cap (accessory) is rotationally engaged with the lid sidewall. The cap and lid can include an interface that creates a liquid and gas impervious seal therebetween. The seal can be provided between a bottom surface of the cap and the top surface of the lid, a feature of the sidewalls of the cap and the lid, or any other sealing interface. The lid can include a score line defining a tear panel, wherein the tear panel can be opened when the score line is fractured. The score line can be fractured using a stay-on-tab, an incisor, a shearing force, etc.

A lid assembly for a beverage can has a base and a closure member that can be swiveled relative to the base between a position in which a drinking port in the top of a can is exposed to allow drinking through the port and a position in which the drinking port is covered. The base is snap fitted over a rim at the top of the can.
