Resealable container lid and accessories including methods of manufacture and use
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.
COATING COMPOSITION FOR METAL SUBSTRATES
The present invention provides novel packaging coating compositions, e.g., food and beverage cans. Preferred cans typically comprise a body portion and an end portion, wherein at least one of the body and end portions are aluminum and are coated on at least one major surface with a coating composition of the present invention. Suitable coating compositions of the present invention comprise: one or more polyester resins, wherein at least one of the polyester resins has a glass transition temperature (Tg) less than about 50 C., and wherein the polyester resin is formed by the reaction of one or more polyacid molecules and one or more polyol molecules; and a crosslinker. Preferred compositions are substantially free of mobile BPA and aromatic glycidyl ether compounds, e.g., BADGE, BFDGE and epoxy novalacs (e.g., NOGE) and more preferred compositions are also substantially free of bound BPA and aromatic glycidyl ether compounds. In more preferred embodiments (e.g., alcoholic beverage cans), the polyol molecules used to make the polyester resin are substantially free of NPG. The present invention also provides a method of making such cans.

Resealable container lid and accessories including methods of manufacture and use
A container assembly including a body and a lid, the lid comprising a rotational and axial guide feature extending radially from a radially interior surface of a lid sidewall. The rotational and axial guide feature is designed to provide axial translation/retention of an accessory when the accessory is rotationally engaged with the lid sidewall. The container and accessory can include an interface that creates a gas impervious/liquid impervious seal therebetween. The seal can be provided between sealing surfaces of the container and the accessory. The lid can include or exclude a bottom wall. The lid can include a score line defining a tear panel in the bottom wall, wherein the tear panel can provide an opening through the bottom wall when the score line is fractured.

Resealable container lid assembly and accessories including methods of manufacture and use
A resealable container lid assembly including a cap rotationally assembled to a lid. The cap rotates between storage, opening, removal and resealing positions. Operation between the cap and the lid employs any suitable mechanical interface, such as cam tracks and cam followers. The lid includes a tear panel defined by a score line. Features of the cap are used to impinge upon the lid to fracture the score line and open the tear panel. Once opened, the cap can reseal the container. 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 cap can include a tamper indicator. The cap can be replaced with any of a variety of specialized caps and/or accessories designed for different functions.
Method and apparatus for controlling an operation performed on a continuous sheet of material
A system and method of performing an operation on a continuous sheet of stock material is provided. More specifically, the present invention relates to a system and method used to perform an operation on a continuous sheet of stock material in a high speed manufacturing system. The continuous sheet of stock material can subsequently be received by a second system that performs a different operation on the continuous sheet of stock material. In one embodiment, the second system forms the continuous sheet of stock material into tabs for container end closures. The system can include an infeed accumulation device and an outfeed accumulation device. The infeed and outfeed accumulation devices enable the system to operate at a variable rate and out of phase with a high speed, coil fed manufacturing system to which the system may be removably integrated. The system can determine if the operation has been performed in at a predetermined location of a portion of the continuous sheet of stock material.
