Abstract: A package (1) of the two-material box type for packaging a product, advantageously a foodstuff, includes an outer envelope (2) which is made up of two envelope parts (5, 6) connected by hinge-forming elements (10) for moving them between—a closed position, so as to jointly define a closed storage volume (1?) intended to contain the product, and—an open position so as to allow access to the storage volume (1?), the two envelope parts (5, 6) being internally covered by one and the same sealed one-piece plastics film (3). The two envelope parts (5, 6) are made up of two separate parts; and the sealed plastics film (3) has an interposed strip (10), extending between the two separate envelope parts (5, 6), so as to form the hinge elements.

Abstract: Apparatus for making a pack tray includes a body with a strip of side walls, the body including an outer envelope lined on the inside with an added sealed plastic film. The apparatus includes at least one station provided with elements for applying glue on a portion at least of the inner surface of the side wall strip of the outer envelope, also called gluing area, before placing a plastic film. The gluing pads include at least one block of a porous material that can, one the one hand, be filled with glue by loading members through a diffusion phenomenon, and that can deposit glue by contact optionally combined with a compression force on the gluing area. The pad is mounted on a bearing structure via members for handling it between expanded positions in which the pad contacts the gluing area for applying glue thereon and a folded position in which the gluing pad is remote from the outer envelope of the pack tray.

Abstract: The invention disclosed herein relates to a packaging try with a thermoformed inner lining. The packaging tray includes, internally, in each corner, a corner panel which is inclined toward the bottom of the tray such that it approaches the center of the bottom. The corner panel is inclined at an obtuse angle with respect to the bottom and to the walls which define the corner. Also disclosed is a unitary packaging tray blank from which the packaging tray is constructed.

Abstract: The machine comprises a thermoforming box (116) which receives the container (126) and which is itself fitted into a cutting box (100), a heating die (148) mounted in vertically slideable manner above the said boxes and capable of squeezing a thermoforming film (44) or a closing film on the upper edge of the thermoforming box and of thermoforming the film (44) inside the container.

Abstract: A moisture-resistant package of the type which is in the form of a tray, constituted of a semirigid material such as corrugated cardboard, and including a bottom (10) and side walls (14, 16) articulated by fold lines to the bottom, and at least two horizontal flange members (24) articulated by fold lines along the upper edges of at least two of the side walls and extending toward the interior of the package in parallel with the bottom. The package includes an impermeable internal lining (28) constituted of a film of thermoplastic material which is applied by thermal molding against the interior faces of the bottom and side walls and which extends without discontinuity against the under face of the flange members (24) and folds over to apply against the upper face of the flange member.
