Resealable container lid and accessories including methods of manufacturing 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.
Coating composition for metal substrates
The present invention provides novel packaging articles, 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 (T.sub.g) 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.
Sealing cap having tamper evidence ring for sealing resealable container and method of use
A plug styled closure cap for resealing a resealable container. The cap includes a body comprising a sidewall, a motion translating feature formed on an exterior surface of the sidewall of the plug style closure cap body that translates a rotational motion to an axial motion when engaged with a mating translating feature formed on an interior surface of a container opening, a sealing surface that engages with a mating sealing surface of the container opening, and a tamper evidence feature integral with the cap body. The sealing surface can include an elastomeric element. The tamper evidence feature can include at least one segment defined by frangible elements. A method of use enables resealing of the container and indication when the container is no longer factory sealed.
