By way of introduction, it should be noted that in the differently described embodiments the same parts with the same reference numerals or the same component designations provided with the disclosures contained throughout the specification the same parts with the same reference numerals or the same component designations transmitted can be. Also, the location information chosen in the description, such as above, below, laterally, etc. related to the immediately described and illustrated figure and should be transferred to the new situation in the event of a change of position. Furthermore you can also individual features or combinations of features from those shown and described different embodiments of their own, inventive or inventive Represent solutions.

1 shows a first embodiment of a packaging container 1 according to the invention.

Shown is a packaging container 1 with a formed by a hollow truncated cone Mantle 2, which is closed by a bottom 4 in the region of a first end region 3 and in the opposite second end region 5, a first opening 6 with a closure element 7 has.

In the region of the first end region 3, one can extend over the circumference of the packaging container 1 extending reinforcing region 8, which is a transition between the shell 2 and the bottom 4 of the packaging container 1 forms. The reinforcement area 8 has a convex with respect to the outer surface of the shell 2 or the bottom 4 Curvature 9 up. The shape of the curvature 9 can, as shown in Fig. 1, formed but may also be in the shape of a quarter circle, i. the curvature runs on the side of the gain region 8 which is the jacket 2, adjacent, approximately parallel to a central longitudinal axis 10 of the packaging container 1 and can at the Floor 4 nearer side of the gain region 8 almost in the vertical direction to the central longitudinal axis 10 run. The advantage here is that the footprint of the packaging container 1, while maintaining high strength, is maintained.

Between these two regions, the curvature 9 can approach a radius of curvature 11 or a radius of an enveloping circle, which is greater than 4 mm, preferably greater than 6 mm, in particular greater than 8 mm, is. According to the invention, it is also possible that the curvature 9 has any other shape of a convex curvature, for example in the region of the reinforcing region 8 which is adjacent to the jacket, not parallel to the central longitudinal axis 10 expires, but in the direction of the first opening 6 out in the essentially conically widened.

Of course, the curvature 9 may also consist of several "partial curvatures". such that curvatures of different radii of curvature 11 to each other connect and thus obtain an optimal for the particular application form.

If the closure element 7 is formed by a peripheral, planar sealing flange, It is possible by the methods known from the prior art, the packaging container with a sealing foil, preferably a metal foil to close. By a corresponding design of the closure element 7, for example by a circumferential curved flange or a circumferential bead, it is also possible elastically deformable cover, for example made of plastic, on the closure element. 7 to snap in a form-fitting manner so as to provide a resealable packaging container 1 to create.

Such packaging container 1 are often in the empty state for the purpose of transport stacked. It can be just in versions that are known in the art are, in the region of the first end portion 3, due to the stacking caused high weight or due to the relatively sharp curves and edges damage caused or may lead to buckling and deformation of the packaging container 1 come. Due to the inventive design of the packaging container 1, such damage can be reduced and due to the higher strength more containers are stacked without damage.

Due to the arrangement of the gain region 8 is further access to the content or the removal of the contents of the packaging container 1 facilitates. Because the radius of curvature 11 in the known from the prior art packaging container 1 or cups very small or the transition from the shell area in the bottom area formed very sharp is, a complete or nearly complete removal of the content was difficult durchzusiihren and a tedious "scraping" with, for example, a spoon needed. The inventive design, the removal of the content can be substantially facilitated be when the curvature 9 or at least parts of the curvature 9 to the one usual spoon, especially teaspoons, is adjusted.

It also proves to be advantageous if the radius of curvature 11 or the radius of a Hüllkreises greater than 6 mm, in particular greater than 8 mm. This is, if larger spoons For example, when common teaspoons are used, ensure that the removal the good or the rest is easily possible.

Furthermore, this embodiment leads to an increase in strength or stiffening in these areas, whereby the handling, especially when filling or in the later use, safer and also buckling stacking is prevented.

The jacket 2 can also be between the first end region 3 and the second end region 5 at least partially by grooves or ribs in the direction of the central longitudinal axis 10, along the circumference are arranged to be provided, which has the advantage of an additional Stiffening and better orientation or fixing the position when stacking the Packaging container 1 provides (not shown in Fig. 1).

Fig. 2 shows a further embodiment of the packaging container according to the invention 1, with a reinforcing region arranged in the second end region 5 in this exemplary embodiment 8th.

The reinforcement region 8 can be used alone or in combination with further reinforcement regions be arranged.

According to the invention, a difference in radius 12 between a largest radius 51 of the Reinforcement region 8 and a radius 52 of the directly adjacent jacket region between 0.4% and 10% of a closure element radius 13. The radii 51, 52, the Closure element radius 13 and the radial differences 12 are understood to be vertical measured with respect to the central longitudinal axis 10. According to the invention it is also possible that this radius difference 12 is between 0.8% and 6% of the closure element radius 13. As a result, transitions in the radius of the packaging container 1 can be rounded off, whereby no or only little residual material can catch at these transitions and thus easier removal is possible.

In this case, according to the invention, the largest radius 51 of the gain region 8 is greater than the radius 52 of the directly adjacent jacket region 2. According to one embodiment However, it is also possible, especially when the jacket 2 in the second end portion 5 approximately is formed cylindrical or konkonkonisch that the largest radius 51 of the gain region 8 is smaller than the radius 52 of the directly adjacent cladding region 2 the transition of the arranged in the second end region 5 shell 2 to the conical running Mantle softens and prevents or reduces catching of residual material and facilitates thus the removal of the content.

By arranged in the second end region 5 gain region 8 also takes place a structural reinforcement of the packaging container 1 or is a deformation in the Lifting of the container by a user reduces.

The packaging container 1 has the reinforcing region 8 in the first end region 3 a curvature 9. This curvature 9 of the gain region 8 has respect a cutting plane contained in the central longitudinal axis 10 on a radius of curvature 11, the 9 may be different in size at different points of curvature. As already the curve 9 may have any convex shape, e.g. also the Shape of a quarter circle, accept. The curvature 9 can also be other convex Have curved shapes and e.g. also be formed by an elliptical section. Advantageous This is especially true when tangents to surface points of an inner side 53 of the Packaging container 1 a steady, non-erratic course of their tendency to transition from the bottom 4 in the gain region 8 and the gain region 8 in the Coat 2 show. In the transition areas between the floor 4 and the reinforcement area 8 or between the gain region 8 and the jacket 2 are in this case on the inside 53 no edges or pointed throats available.

According to the invention it is further possible that a wall thickness 54 of the packaging container 1 in the area of the shell 2 between 10% and 40%, in particular between 15% and 30% a wall thickness 55 in the region of the gain region 8 amounts (in Fig. 2 by the hatched area indicated). This offers the advantage of material savings and thus lower production costs. The necessary structural strength is nevertheless given because of the reinforcement areas arranged in the first end area 3 and in the second end area 5, respectively 8 and closing element 7 an increase in strength is achieved.

According to the invention, the packaging container 1 can be made of a plastic film, in particular be formed by a deep drawing process. The production or molding by injection molding However, spray-stretch blow molding is also possible.

The material for forming the plastic film can be selected from the group of polypropylene, polystyrene or polyesters. As a result, the raw material costs can be kept low and allows the use of these materials in addition to food safety one relatively uncomplicated processing.

Polypropylene packaging containers have good strength and lower rigidity Density, at the same time good stress cracking resistance. They retain their characteristics Also at higher temperatures, which also provides a packaging of warm Good or a heating of the content in the packaging container 1 according to the invention possible is.

Polystyrene in its basic form is clear-sighted with high rigidity and hardness. However, it is According to the invention also possible to color the material to the appearance of the Packaging container to adapt to the respective requirements. By use Due to the high strength of these materials, the wall thicknesses of the packaging container are possible to a minimum, which in addition to the costs and the weight reduced and thus brings advantages among other things in the transport of the container.

Fig. 3 shows a further embodiment of the packaging container according to the invention 1, with an additional, arranged in the region of the shell 2 weakening range 16th or a second opening 15.

It should be noted at this point that individual components of the individual design variants are transferable to the other embodiments, e.g. the arrangement of Reinforcement areas 8 or the arrangement or formation of openings on the packaging container 1 or formations with rectangular or triangular cross-section or cylindrical or konkonkonische forms, so that these parts description accordingly are transferable, even if not explicitly in the individual embodiments Reference is made to this.

According to the invention, it is possible that in the region of the jacket 2 of the packaging container 1 a second opening 15 or a trained for producing a second opening 15 first weakening region 16 is arranged. By such a configuration it becomes According to the invention possible, not only through a first opening 6 access to the contents of the packaging container 1, but if necessary, through this second opening 15th to take the contents. The preparation of the second opening 15 can already at the actual Forming process of the packaging container 1 done by, for example, Aussparrungen are arranged in the mold. Also subsequent punching a second opening 15 is possible, which is advantageous in more complicated forms of the second opening 15.

For example, the unwanted falling out of the content or the view of the content To prevent is possible according to the invention, the second opening 15 initially closed train. This can, for example, by a seal with a foil or a Punching along a line of weakness in the weakened area 16 done. If necessary can by tearing up or tearing off a first weakening area 16, the access to the content be released.
