Abstract
Embodiments of the present invention include food and beverage packaging utilizing heat seal technology, and specifically include food and beverage containers with end closures having seals or liners and snap-fit closure mechanisms. In some embodiments, the food and beverage containers and the end closures are metal. In further embodiments, the food and beverage containers include a domed portion on the bottom closed end. The end closures can snap onto the food and beverage containers such that the packaging is reclosable. Moreover, the sealed packaging with reclosable features can retain a variety of internal pressures including pressures higher than possible with the heat seal alone.
