DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a deep-drawn plastic packaging cup.
2. Description of the Related Art
Packaging cups are known in great number and serve, e.g., in the packaging of dairy products, such as yogurt, cottage cheese, sour cream and the like. The objective involved here is to produce such packaging cup, for cost and/or environmental reasons, of a minimal amount of material, that is, with a wall as thin as possible, while nevertheless guaranteeing sufficient stability and/or labelability. Known from EP-B-0 408 515, is a packaging cup whose wall is surrounded by a cardboard sleeve which, by narrow form-fit, is in contact with the plastic part. A disadvantage here is that the cardboard sleeve must be inserted into the mold ready for the fabrication of the packaging cup. The plastic cup is then molded to the cardboard. Furthermore, the cardboard sleeve represents a relatively high material consumption. In turn, this results in the need to produce at the manufacturer's, a correspondingly great number of packaging cups with appropriately changing labeling, and to stock them in keeping with the plurality of goods to be packaged. A correspondingly high stocking is also required at the customer's filling facility.
Known from DE-A-24 03 935, moreover, is a packaging cup whose wall features a flat wall part and an otherwise cylindrical or truncated-cone-like round wall part. The packaging cup has molded to its top rim a flanged rim that protrudes radially outward. Since the flanged rim has along the flat wall part the same width, the packaging cup is relatively unstable in the area of the flat wall part. Furthermore, the packaging cup features in its center area, outside the flat wall part, a shoulder serving as a stacking rest, which imparts a certain stiffness to the packaging cup, but causes a relatively large stacking interval between two adjacent, stacked packaging cups.
SUMMARY OF THE INVENTION
The objective underlying the invention is to create a packaging cup of the initially named type whose strength properties are sufficient while its material consumption is low.
This objective is satisfied by retaining a round flanged rim even along the flat wall part which surprisingly gives a considerable strength of the packaging cup, even with reduced wall thicknesses, thereby, lowering material consumption. The flat wall section lends itself more easily to labeling the packaging cup, e.g., by imprinting or affixing, for example gluing a blank to it, for example a labeling sticker or band. Additionally, it is possible for the labeling to take place not at the manufacturer's of the packaging cup, but at the user's, that is, the filling facility. This creates considerable advantages, since the manufacturer may produce such packaging cups irrespective of subsequent labeling in one style and, consequently, labeling may take place individually at the filling facility. The benefit to both the manufacturer of the packaging cup and the user is considerable economization by inventory reduction and simplified handling. The stable design of the flanged rim, and thus of the flat wall part, also allows a small stacking interval between adjacent nested packaging cups thereby improving stacking and further handling.
The expression "labeling" as used here and hereafter is to be understood in its most general form and is meant to include any kind of notably visual design and decoration and/or marking of the cup contents and/or marking for other references.
The stability of the cup part can be improved by the wall including a reinforcement shoulder. Basically, it is possible for the packaging cup to have a cylindrical basic shape, which may be tapered conically downward, which allows economical stacking of the packaging cup. The stability of the packaging cup allows improvement by a flanged rim having a segment section which features a downward beading, since not only the surrounding round flanged rim contributes considerably to the stability of the packaging cup, but addition
