Abstract: A laminated container structure in which a peelable coupon or the like forms an integral portion of the outer ply of the container wall and is defined by a perforated tear outline. In one embodiment, a release agent is coated on the back of the coupon area to prevent adherence of the coupon to the adhesive joining together the outer and inner plies of the container. In another embodiment, the inner ply is formed of cylinderboard adhesively fastened to the outer ply, the perforate coupon tear outline extending through the outer ply, adhesive and outermost layer of the inner ply so that peeling of the coupon will not remove the inner layers of the inner ply and thus not destroy the integrity of the container.

Abstract: A laminated carton comprising a paper board substrate and an outer paper ply including a peelable section in the paper ply defined by a perforated tear outline providing a leading edge, said ply being bonded to the substrate by a water soluble laminant coated with a release agent in a pattern which includes voids in the coating at said leading edge, said voids being shaped to provide variable adhesive bond between said plies as peeling of said section is initiated after application of moisture to the area of said leading edge to dissolve said laminant at said voids.

Abstract: A laminated or multiple-ply container structure comprising an inner wall of a substantially rigid material and an outer wall of a thin, generally pliant material, such as a glossy finished paper, adhesively fastened thereto by a suitable adhesive or glue. Formed in the outer wall of the container, as an integral component thereof, and through the intermediary of a tear outline constituted of perforations extending through at least the outer ply or wall is a section constituting a readily removable or peelable coupon-like panel, with the peeling off of the panel adapted to be effectuated without adversely affecting the integrity of the container structure or necessitating the use of special cutting instruments or tools.

Abstract: A laminated or multiple-ply structure comprising an inner wall of a substantially rigid material and an outer wall of a thin generally pliant material, such as a glossy finished paper, adhesively fastened thereto by a suitable adhesive or glue. A plurality of artifact receiving pockets are formed in the thin outer wall of the container, with each pocket being formed through the intermediary of a suitable perforation configuration formed therein. Each perforation configuration includes slits penetrating through the outer wall material and defining a pocket by a plurality of discontinuous slits extending along the semicircular peripheral edge of the pocket.

Abstract: A novel membrane-to-closure mouth structure is effected by causing a paraffin-based heat activatable peelable sealing ply on a thin metallic foil to adhere to a sealing face of a closure mouth composed of a polymer such as polyethylene by electromagnetically inducing intense abbreviated heat in the foil and consequent focusing of the heat activation necessary for resin migration under pressure to form a water and gas transmission barrier in a frangible sealing ply structure composed primarily of low tensile strength waxes complemented by tackifying materials.
