Abstract
A bowl package, specially to contain portions of food, e.g.
animal foods or the like, requiring sterilisation, with a lower part open at the top made of sheet metal like aluminium or steel, in the shape of a bowl, a hollow cylinder or the like, on the upper edge of which there is a circumferential sealing edge formed in one piece with the lower part, the upward-facing sealing surface of which is substantially parallel to the bottom surface of the lower part, a continuous internal coating covering the inside of the lower part and its sealing surface as corrosion protection preventing contact between the package contents and the sheet metal of the lower part and a sealing foil of metal foil, paper or the like which has a sealing foil coating on the underside facing the lower part, whereby the choice of material for the internal coating and the sealing foil coating is made using a plastic and a sealing lacquer component like polypropylene, polyethylene, polyethylene terephthalate or polycarbonate or a sealing lacquer compatible therewith in such a way that, when the sealing foil is pressedagainst the sealing edge in a sealing tool or the like with the application of heat and pressure, a substantially gas and damp-proof sterilisable seal is obtained between the sealing foil and the lower part, in which the internal coating of the lower part consists of a sealing lacquer layer and the sealing foil coating (16) of a plastic foil.

plastic foil of the above-noted type, as a result of which it is prevented that the package content comes into direct contact with the corrosion-sensitive sheet metal of the lower part, which can e.g. also ~ be an especially thin steel plate. The sealing foil coating consists of a sealing wax, which is applied in flat layers to the sealing foil and ensures that the sealing foil is sealed with the lower part so as to be impermeable to gas or fluids by pressing on the sealing edge of the - lower part using appropriate pressure and appropriate heat.
Bowl-shaped packages of this type have proved quite successful.
However, it has been found to be disadvantageous that the choice of material for the sealing foil could not as yet be satisfactorily solved.
This is due to the fact that the sealing foil is covered, in conventional bowl-shaped packages, with a very thin sealing wax layer on its side facing the lower part and this layer cannot, for its part, absorb any mechanical stresses in the foil plane and it must also be made so as to be relatively tear-resistant as well as flexible and rollable. As a result of this, the possible choices of material are restricted since neither especially thin e.g~ aluminum foils can be used which could otherwise tear easily when transported or even at the point of sale when the sealing foil is subjected to e.g. an impact stress, nor can any relatively inexpensive materials be used, such e.g. paper or the like.
'' It is the object of the invention to further develop the conventional bowl-shaped package in such a way that, while retaining the ability to sterilize, a greater flexibility is attained with respect to the choice of material for the sealing foil, whereby the bowl-shaped package should be sturdy and dependable when used.

coating of the lower part consists of a sealing wax layer and the sealing foil coating consists of a plastic foil.
It can thereby be provided that the sealing foil coating is applied to the inner surface and the sealing edge of the lower part as molten or solvent film.
It can also be provided, according to the invention, that the sealing foil coating consists of a uniaxially or multiaxially (highly) stretched plastic material.
The invention is based on the surpising realization that it is possible to solve the object of the invention by shifting the function of the plastic foil, which is used as a corrosion coating for the lower part in the prior art and can merely "act out" its corrosion-resistant properties without using the additional inherent property of plastic foil, namely its viscosity and high mechanical stability, to a more proper position, namely, by developing it as a sealing foil coating, whereas the sealing wax, which was thusfar provided in the prior art on the sealing foil, is used as inner protective coating for the lower part.
In the invention, the sealing wax which is not in a position to assume mechanical functions thus serves two functions as inner coating for the lower part, namely, on the one hand, to ensure a reliable protection against corrosion of the lower part, in addition, however, also, as in the prior art, to enable a reliable sealing in connection with the plastic foil, whereas the plastic foil, as sealing foil coating, brings to bear its properties which are not used in conventional bowl-shaped packages, namely viscosity and high lateral mechanical strength. Since, as a result, the actual sealing foil material is relieved, for the :
:~ :

:
: :
' .
greatest part, of the functions of mechanical viscosity and lateral strength, the sealing foil material, for example then the aluminum or steel sheet used, can be made essentially thinner than in conventional ~ -bowl-shaped packages, including having all the cost advantages associated therewith. Also, materials can be used which could thusfar not be used, such as e.g. paper or the like, i.e. materials having only slight mechanical strength.
On the whole, it is hereby made possible to create an essentially less expensive bowl-shaped package which possesses, moreover, improved strength properties with respect to the sealing foil.
Additional features and advantages of the invention can be seen in the following description in which an embodiment of the invention is explained in greater detail with reference to the schematic drawing.
The drawing, which consists of only one figure, thereby shows a `
bowl-shaped package according to the invention, in a vertical section through the longitudinal axis.
As can be seen in the drawing, the bowl-shaped package of the invention has, in the embodiment shown there, a lower part 10 which here consists of sheet steel with a thickness of O.l mm and is produced in a cupping process. The lower part 10 is, on its inner surface, including a sealing edge extending essentially parallel to its base surface, coated with an inner coating 12 of sealing wax which is made so thick that the sheet steel of the lower part 10 is protected against corrosion and a reliable seal is also made possible. A sealing foil 14, consisting of very thin aluminum foil, is provided on its lower side with a sealing foil coating 16 in the form of a polypropylene foil. By means of a sealing tool, the sealing foil 14 can be joined in a known manner with ' ' ', , " , ', , ; ' , ' ' ' ;' ' ' .
the lower part 10, along the sealing edge, by using pressure and heat so as to be impermeable to gas and fluids, whereby it can be ensured, by appropriately selecting the sealing wax for the inner coating 12 and the material for the sealing foil coating 16, that the filled and sealed package can be sterilized.
Of course, the basic idea of the invention, to provide the corrosion-sensitive lower part with an inner coating of sealing wax, simultaneously serving as a corrosion layer, to furnish, on the other hand, the sealing foil 14 covering the lower part with a sealing foil layer which can be mechanically stressed and is compatible with the sealing wax of the inner coating 12 of the lower part 10 in the form of r a mechanically stressable plastic foil, cannot only be used in bowl-shaped packages of the above described type but also e.g. in can-like containers and the like.
