Patent

CA 2172427

A container for packaging a particulate product under pressure or vacuum conditions with an easy opening closure structure which allows venting prior to uncovering of the product opening. In one form, an easy peel flexible lid covers a shelf area and a product opening in the top of the can. Peeling back the lid first uncovers the vent opening, permitting the flow of gases but preventing the flow of particulate product, and then uncovers the product opening. Alternatively, the closure structure may be formed by multiple layers of a flexible material, the lower layer of which has the vent opening which is uncovered by peeling back the top layer, after which the product opening is uncovered.
