ABSTRACT:
A package includes a peripheral flange around a blister defining an open cavity for receiving a product and a compressible insert for securing the product against movement in the cavity. At least one projection on the insert extends laterally from the cavity over the peripheral flange, and a lid covering the cavity is continuously sealed to the peripheral flange and the projection along a single seal. A method for sealing products in the package includes supporting the peripheral flange on a rigid support surface, and compressing the lid against the peripheral flange with heat and pressure to compress the projection between the lid and the peripheral flange and heat seal the projection to the lid simultaneously with sealing of the lid to the peripheral flange along the peripheral seal.
