Abstract: A package with a food product therein is provided and, in particular, with a coffee product, comprising at least an inner package and at least an outer package, and having at least one means for reclosing provided on the inner package and/or on an inner side of the outer package. Alternatively, the inner package may comprise a vacuum-packed inner package with an outer package. A machine for producing a packaged food product is also provided and, in particular, for producing a packaged coffee product. The machine comprises at least one device for applying a means for reclose to the inner package and/or to the inner side of the outer package, the device provided in the machine direction upstream of a device for providing the at least one outer package around the at least one inner package.

Abstract: A process for producing composite bodies from a plurality of molded pieces made from quartz materials of different or identical structure, preferably fused quartz and/or fused silica. Also, composite bodies produced according to this process. A prismatic molded piece with a rectangular bottom surface and top surface and four plate-shaped molded pieces whose dimensions are tailored to the outer surfaces of the prismatic molded piece are produced in a first step, the plate-shaped molded pieces are then fixed to the outer surfaces of the prismatic molded piece, the prismatic molded piece and the plate-shaped molded pieces are heated together under protective gas to a predetermined temperature T&egr; above the softening temperature of the quartz material and then cooled, resulting in a prismatic composite body which is joined thermally in a material engagement and which can be severed to form a series of plate-shaped composite bodies.
