Abstract
Abstract An imbricated package of closed-end bags comprising a plurality of bags arranged so that each preceding bag overlies the top end of the following bag, an adhesive support member for the bags where each bag prior to the last, bottom bag is releasably adhered at its top end to the support member, each bag including (a) a seal for releasably sealing the bag at its top end and (b) adhesive means disposed on the outer surface of the bag above the seal, the adhesive means releasably securing each bag to the underside of the bag preceding it, the strength of the adhesive connection established by the adhesive means being greater than that of the seal so that as each preceding bag is removed from the package, the seal is peeled open to open the following package, and the strength of the adhesive connection between the following bag and the support member being greater than that established by the adhesive means so that the following bag is not removed from the support as the preceding bag is removed from the package.
