Abstract
A blank and a container formed from the blank is disclosed which comprises a first member having a first thickness which includes a bottom field and a plurality of side fields which project upwardly from the bottom field to define a cavity when the blank is formed into a container. The side fields include side edges which define cut-out portions between adjacent side edges. A second member having a second thickness less than the first thickness is provided and arranged in overlying relation to the first member and extends beyond the side edges of the side fields to completely fill the cut-out portions. The portion of the second member that fills the cut-out portions can be folded upon itself to define sealing flap means when the blank is formed into a container, the sealing flap means being operative to seal adjacent side fields together along their side edges.
