Abstract

See full text

A package comprising a paperboard carton having an open end which is closed by a hingedly connected plastic lid, the lid and the carton together forming a latch to hold the lid in its closed position prior to initial opening of the package and between dispensing cycles. In a particularly preferred embodiment, the plastic lid includes a 'U' shaped channel about its periphery, the channel having a projection located on one of the innermost surfaces of the 'U'. The open end of the paperboard carton includes a folded over flap. Either the flap or the carton sidewall to which it is attached includes an aperture which is complementary in size and shape to the projection on the plastic lid. The lid is maintained in its closed position by entry of the projection on the 'U' shaped channel of the plastic lid into the aperture in the paperboard.
