ABSTRACT:
A package comprising a consumable product and a sealed container containing the consumable product. The container is made up of a folded and sealed sheet of carton material having an opening therein defining a product-viewing window and a sheet of clear film material disposed over the opening so as to close the opening while retaining the product-viewing capability of the window. The clear film sheet has a marginal periphery disposed in lapped relation to a marginal periphery of the carton sheet and a wave energy curable adhesive between the marginal periphery of the clear film sheet and the marginal periphery of the carton sheet in a cured by wave energy condition bonding the clear film sheet over the carton sheet opening so that the bond cannot be rebonded by the cured adhesive once the bond provided by the cured adhesive between the sheets has been broken. The container is erected from a flat blank consisting of the carton sheet, the film sheet and the cured adhesive. A method and apparatus is disclosed for making the flat blank.
