Abstract: An apparatus for transporting and storing cooked food and one-course meals includes a box-shaped, upright container with wheels and at least one pivoting front door. The container can be closed by the front door in an air-tight manner. The container has at least one air valve toward the outside that can be closed and opened, in addition to a device for measuring and storing and displaying the temperature and pressure inside the closed container, so that temperature and pressure can be read from outside of the container. Data can be read by a personal computer and presented in the form of diagrams, as a function of time, over a period of at least 14 days. The cooked food is, initially, cooled at a temperature of between 2° C. and 4° C., and is then exposed to a vacuum for enabling the cooked food to be kept fresh for up to 14 days.

Abstract: As part of a method for producing a combination packaging container (28), which combination packaging container (28) comprises a beaker-shaped plastic inner part (15) and a casing-type outer part (14) surrounding the plastic inner part (15) and retained on the external face of the plastic inner part (15) in an interlocking arrangement, and by which method the two parts (14, 15) are pushed one in the other in an interlocking arrangement, the assembly process is improved due to the fact that the outer part (14) is retained in a holder (13) and the plastic inner part (15) is introduced into the outer part (14) retained in the holder (13) and then pushed down into the outer part (14) so as to interlock.

Abstract: A deep drawn plastic packaging cup which includes a wall having a bottom, a round cross section wall part being one of cylindrical and truncated-cone shaped, and a round radially protruding outward flanged top rim. A flat wall part extends through a chord of the round cross section of the deep drawn plastic packaging cup wall, and a circulate segment section is formed with the top rim and joined to the flat wall part.

Abstract: The packing container has an outer container shaped from a card blank (7) and an inner container deep drawn from a plastic sheet. The strong, but manually detachable connection between the outer and inner containers of the packing container takes place positively, in that during the deep drawing of the inner container bulges are formed in its wall, which penetrate cutouts (39 to 44) of the outer container. Thus, for separate waste disposal purposes, the outer container can be completely and easily separated again from the inner container.

Abstract: For a separate waste disposal of the aluminum foil inner coating (9) of a packing container produced in a winding process, the overlapping foil edges (16, 17) are only glued together at a distance from a foil outer edge (18). The unglued overlapping foil edge (21) makes it possible to peel the inner coating (9) from the cardboard body, after removing the bottom diaphragm of the packing container. The peeling movement starts on removing the bottom diaphragm, in that its rim is glued to the unglued, overlapping foil edge. A gripping tab is provided on the bottom diaphragm to permit the removal thereof.

Abstract: Container (1) comprises a relatively rigid outer container (2) and an inner container (3) forming an inner lining. Inner container (3) is manufactured from blanks of thin, plastic-coated aluminum foil and has welded overlap seams running along a fold. The outer container protects the inner container (3) ensuring the necessary tightness against damage leading to leaks. Except for an aluminum coating of less than 0.02 mm thick, which ensures the tightness and light protection, the container is made from plastic, or in the case of outer container (2) from some other combustible material. Its temperature loading and tightness characteristics make container (1) suitable for packing foods to be sterilized, as well as for carbon dioxide-containing drinks. The container is conical for space-saving transportation purposes.

Abstract: For separate waste utilization of the plastic and cardboard parts of a used packing container (1), the cardboard sleeve (5) reinforcing its circumferential wall (2) and only positively connected thereto has a desired separation strip (10), whose operation leads to the separation thereof. The desired separation strip (10) is formed on the overlap area of the cardboard sleeve (5). It only has one weakening line (16) bounding it on one side and concealed by the overlap. On tearing, the inner overlap edge (13) acts as a cutting edge for the outer overlap layer.

Abstract: The flange-like lid rim of a packaging container, including the outwardly projecting gripping part shaped thereon, is laterally enclosed by an all-round rim portion, so that it is not accessible for opening the packaging container. The actuation of the gripping part leads to the separation of a rim extension of the container body engaging below the gripping part and to which the latter is non-detachably connected by a pushbutton connection. The sealing fixing of the lid to the container body takes place by interlocking engagement beads. The packaging container avoids any hot sealing joint as a guarantee seal and is made from completely burnable plastic.

Abstract: The packing container comprises a cylindrical cardboard body produced in a wrapping process and whose inside is lined with an aluminum foil and is provided with container bases fixed to its ends. The container bases comprise an aluminum foil with a cylindrical border and a cardboard plate or board fixed to the planar part of the container base. This cardboard plate protects the thin aluminum foil. A tear-open grip is provided on one of the container bases and is shaped through a u-shaped punching line from the cardboard plate and the aluminum foil fixed thereto. The opening formed by the punching line is closed by a foil portion, which is stuck to the bottom of the container base. On opening the packing container, the connection between the cylindrical border of the container base and the inner face of the container body is torn apart.

Abstract: During the deep drawing of a cup-shaped container from a plastic sheet, its wall is surrounded by a sleeve of cardboard material or the like which reinforces and insulates the container and can be used to carry decorations. The upper and lower edges of the sleeve are enclosed by radial protrusions of the plastic of the container so that they cannot come into contact with the moisture of a base surface. Positive engagement between sleeve and container is ensured and the sleeve supports the wall which can be made very thin.

Abstract: A seal and closure for a container end includes a metal foil seal having a cylindrical part sealed to the inner surface of the container adjacent the end, a transverse diaphragm part recessed inwardly from the end, and a tear tab on the diaphragm. An annular groove is formed in the cylindrical part between the container end and the diaphragm, the groove defining a tear line so that the membrane and the inward portion of the cylindrical part separate from the remainder thereof when the tear tab is pulled. An insertable lid covers the seal.

Abstract: A pull-tab can closure of a thin metal foil membrane less than 0.15 mm. thick is provided with a peripheral scoreline for easy opening. The provision of a peripheral scoreline in a thin metal foil membrane is made possible by providing a flexible portion of the membrane parallel to and inside the radius of the scoreline. The flexible portion may be in the form of an inclined area relative to the scoreline or in the form of one or more concentric groove-like convex areas inside the radius of the scoreline. A method of making the closure and stamping means having a beveled score-forming edge are also disclosed.

Abstract: The exposed edge of a box is covered by placing a strip of heat-shrinkable PVC around the box so that it projects axially beyond the box edge and heating the strip so that the projecting portion shrinks and bends over the box edge, covering it. The projecting portion can be made to project far enough so that, when the strip shrinks and bends, a portion protrudes inwardly beyond the box edge. That protruding portion is then pressed against the inner box wall by a fitted lid or mandrel. A second strip can then be applied in similar fashion and shrunk to form a guarantee seal between the box and lid. An end of the second strip is left free to provide a seal tearing grip.

Abstract: A rupturable seal for a container of the type having an insertable lid wherein the seal constitutes a membrane having a cylindrical portion extending into the open end of the container to beyond the insertion depth of the lid, the upper edge of the cylindrical portion being adhered to the inner surface of the container, the seal having a transverse portion extending across the interior of the container to close it. A tear strip surrounds the cylindrical portion between it and the inner surface of the container and protrudes through an opening in the cylindrical portion to form a holding flap which can be pulled, after the lid is removed, to rupture the membrane which is then removed. An upper portion of the membrane wraps over the open edge of the box to form a protective covering therefor which remains. In an alternative embodiment the tear strip extends around the inner surface of the cylindrical portion and is adhered thereto.
