DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a disposable package, designed particularly for fast food, such as hamburgers with french fries.
Whenever possible packages of this kind should be manufactured from paper, cardboard, corrugated board, porous cellulose or any other material which is easily decomposed, i.e. compostable. Further, the material should be a porous material or a material with several layers with air spaces in between. In some cases the package should be provided with a lid, and in certain cases divided up into two sections, if a sauce, french fries or similar items are served with the fast food. In addition, the package must readily facilitate easy eating of its contents and prevent spillage.
Several varieties of containers or packages of this kind have been proposed for the above mentioned purposes, resulting in major storage requirements for packages and adding to the cost of handling.
SUMMARY OF THE INVENTION
The objective of the invention is to provide a disposable package which meets all the above demands, so that it is necessary to store only one single type of package, and one which is, particularly suited for eating from.
A disposable package, particularly for fast food, such as hamburgers with french fries, is provided comprising two deep bowl-shaped sections which are interconnected along a common edge line and have each an outer edge line of one package wall, parallel to the common edge line, which outer edge lines, together with the common edge line and intermediate, uppermost, essentially longer side edges of the longitudinal walls of the package sections are disposed essentially in one and the same plane. According to the present invention the two bowl-shaped sections are foldable along the common edge line, and the two package walls, which are defined by the said outer edge lines, are extended upwards by means of flaps or tongues which form a coupling pair, e.g. of the male and female type, so that both bowl-shaped sections, when folded together, may be locked by means of the coupling pair or, when needed, an additional disposable package of an identical type, disposed upside down, may be placed on the package, and connected thereto by means of the coupling pairs.
According to the invention it is preferable that the longitudinal sides of at least one of the package sections are provided with two slots and/or tearing lines that extend from the uppermost side edges and along the major portion of the height of the side walls at a distance from each other of at least two to three thumb widths.
The two slots and/or tearing lines of each one of the said longitudinal walls are designed to define a tearing flap, preferably tapering downward.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention and the advantages attained thereby are illustrated in more detail below with reference to the accompanying drawings, which diagramatically show one embodiment of the invention, picked as an example, and wherein
FIG. 1 is a perspective view of the disposable package, intended to be used for a hamburger with french fries, and
FIG. 2 is a frontal view of the same package, completed by a further, identical package, turned upside down, applied as a lid; whereas
FIG. 3 is a perspective view, resembling FIG. 1 but illustrating a slightly modified embodiment, and wherein, finally,
FIG. 4 is a perspective view of the disposable package of FIG. 3, completed by a further, identical package, turned upside down, applied as a lid, and completed with a carrier device.
DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 shows the disposable package, which is made from very finely dimensioned corrugated cardboard with a bowl-shaped container section 1 for a hamburger and another equally large bowl-shaped container section 2 for french fries. The two sections 1 and 2 of the package are integrated along a common edge line 3, which constitutes an uppermost boundary for one of the end walls 4, 5, of each package section 1, 2. The other end walls 6, 7 of the package sections are defined upwardly b
