Description

The invention relates to a cup made of plastic, which has a thin-walled jacket, which is closed in the region of a first end portion by a bottom and in the opposite second end portion having a first opening with a closure element, and a transition region from the shell into the ground in a through a Central axis of the cup extending plane has a convex curvature with respect to the outer surface of the shell or bottom.

The production of cup-shaped packaging containers made of plastic for receiving dairy products has long been known. Here, plastic cups are deep-drawn with a more or less downwardly tapering body or produced by similar methods. The resulting cup shape is on both the outside and on the inside strictly conical with mostly sharp-edged transitions to a cylindrical or konterkonischen training in the upper, near the opening area and sharp or formed by small radii transitions from the conical region to the bottom region.

Due to these sharp-edged or small-radius transitions or edges, the removal of the contents, which preferably takes place by means of spoons or spoon-like objects, is made more difficult in these areas, especially during the transition from the bottom to the conical jacket and in the transition to the counter-conical part.

The patent US 5,628,453 A1 describes a packaging container from a cup-shaped plastic part, which has a thin-walled jacket. This cup-shaped plastic part is closed in the region of a first end region by a bottom and, in the opposite second end region, has a first opening which can be closed with a closure element. In a transition region from the shell into the ground, the cup-shaped plastic part has a convex curvature with respect to the outer surface of the shell or bottom in a plane passing through a central longitudinal axis.

The German utility model DE 81 07 433 U describes a packaging container from a cup-shaped plastic part with a thin-walled jacket. This cup-shaped plastic part is closed in its first end region by a bottom and has in its opposite second end region on a first opening which is closed by a closure element. On the bottom side, all wall sections of the oval-shaped cup pass over a curve into the likewise oval-shaped edge of the stand or floor.

The patent application JP 10 305861 A shows a cup-shaped packaging container, which has a convex curvature in the transition region from the jacket in the ground, wherein additionally a stand edge for the cup-shaped plastic part is still arranged in the bottom area. The patent application JP 10 324369 A merely describes a receptacle formed elliptical in cross-section, wherein on diametrically opposite sides of the container projections are formed, with which the cup for the opening process can be biased or compressed by the closure element and thus spilling or scattering of the stored medium in the interior is prevented ,

In the document AT 338 164 B described cup the beaker wall is slightly conical below the undercut and flanged cup rim and in the transition region towards the cup bottom part is a more conical ausgestalteter bottom area available. In this more conical recessed bottom area additional bulges are provided, which should prevent according to the stated object of the invention, the inclusion of air bubbles in the filling of such a cup in this area.

The invention is therefore an object of the invention to provide a packaging container whose configuration facilitates access to the content or its removal, while maintaining high stability, and also allows the axial fixation of a jacket-like outer part.

The object is achieved in that arranged in the region of the curvature in the transition region at least one at least over 50% of the circumference extending reinforcing region is whose convex curvature in the plane passing through the central longitudinal axis, a radius or a radius of an enveloping circle which is greater than 4 mm and that a wall thickness in the region of the shell between 10% and 40%, in particular between 15% and 30 %, a wall thickness in the region of the reinforcement region, wherein between the jacket and the reinforcement region a shoulder is formed, which protrudes exclusively on the outside of the cup.

The advantage here is that a packaging container can thus be made available in which no or only little residual material at edges or behind edges or sharp-edged radii or transitions of areas in the jacket change their diameter or transitions from the jacket area to the floor area. catch. Due to the large radii of these transitions, it is advantageously possible with customary on the market spoons, especially in the size of commercially available teaspoons, on the packaging container wall or in the region of the bottom, in particular in the transition between bottom region and jacket of the packaging container, adhering, in particular pasty Restgut easy and almost completely remove. The removal of the remainder can be done, as usual in the prior art cups, tedious and yet still mostly incomplete, "scraping" of the rest. In addition to a more complete utilization of the content, the smaller amount of residual material remaining in the cup further reduces the disadvantage that the problems of bacterial decomposition of the residual material and the corresponding odor nuisance associated with disposal in the garbage during possibly prolonged storage are reduced. Through the shoulder holding means for the axial support of a possibly placed around the cup shell-like outer part is formed at the same time.

According to one embodiment of the invention, provision is made for a second opening or a first weakening area formed to produce a second opening to be arranged in the area of the jacket and / or the floor. An arrangement of a second opening or a weakening area formed in the region of the jacket and / or the bottom for the purpose of producing a second opening is advantageous since it makes it possible on the one hand to create a further access area to the contents of the container, and on the other hand to specify further embodiments of the packaging container which facilitate the extraction or access to the content, such as the possibility created thereby is to arrange an additional receiving space behind the opening or the weakening area formed for the production of the opening and thus to provide the opportunity to easily remove a content contained therein or to pack this content separately from the rest of the content.

It is also advantageous if the radius of the convex curvature or the radius of the enveloping circle is greater than 6 mm, in particular greater than 8 mm, since thereby also with larger spoons, or spoons with larger radii, the residual material can be easily removed.

According to a variant embodiment, it is provided that a radius difference between the largest radius of the reinforcement region and the radius of the directly adjacent jacket region is between 0.4% and 10% and between 0.8% and 6% of the largest radius of the closure element, as this causes edges be avoided in the transitions of these areas and it is effectively prevented by the rounding that can catch residual or is facilitated removal with, for example, a spoon.

The fact that the largest radius of the reinforcement region is greater than the radius of the directly adjacent jacket region provides the advantage that a projecting region is created which simplifies the handling of the container.

According to an embodiment of the invention whereby the largest radius of the gain region is smaller than the radius of the directly adjacent cladding region, the advantage is achieved that transitions with tapered diameters can be better rounded.

Due to the configuration according to which the reinforcing region is arranged in the region of the jacket region close to the first opening, the advantage is achieved that the packaging container will lose a high stability in this upper region and thus there will be no or little deformation when holding the container.

It is also possible that the reinforcing region is arranged in the region of the jacket region located near the bottom, whereby in this region an increased stability of the packaging container is reached and a buckling and thus falling over when stacking or use of the cup is avoided.

Furthermore, it is advantageous that the difference in radius between the largest radius of the bottom and the largest radius of the reinforcement region is between 8% and 22%, in particular between 12% and 18% of the largest radius of the closure element, since this creates a round transition, thus providing a Removal of the remainder with a conventional spoon, such as a teaspoon, can be performed easily.

Characterized in that between the closure element and the reinforcing region is formed at least one recessed towards the central longitudinal axis of the packaging container receiving space, the advantage is achieved that it is possible to arrange accessories, such as spoon, in the cup separately from the rest of the content.

According to one embodiment, according to which it is possible for a receiving space recessed in the direction of the central longitudinal axis of the packaging container to be formed in the region of the base, identification features of the container can be arranged or accessories can be integrated which are visible or removable, for example, by turning the packaging container upside down are.

There is also the possibility that the recessed receiving space adjacent to the second opening or the first weakened area, which has the advantage that when removing the goods no edges interfere.

It is also advantageous if at least one jacket-like outer part surrounding the packaging container is arranged in the region of the jacket, since the container is thus given greater stability and deformation during use is reduced.

According to a further development, it is provided that a further opening or a further weakening area designed for producing a further opening is arranged in the shell-like outer part, whereby it is advantageously possible to selectively release or close the access to underlying areas by turning the jacket-like outer part.

Furthermore, there is the possibility that the further opening is designed to be resealable, whereby a protection of this content is ensured after return of the content in the receiving space.

Advantageously, a sealed seal is arranged in the region of the second opening and / or in the region of the further opening.

It is also advantageous if between the shell-like outer part and the jacket another coat-like outer part is arranged, as this information that is printed on the other coat-like outer part, can be passed.

It is also possible that the shell-like outer part consists of a cardboard material whereby an additional reinforcement or stiffening effect of the packaging container is achieved.

According to one embodiment, it is provided that the shell-like outer part consists of a plastic material, whereby a sorted disposal or low production costs are achieved.

It is also advantageous if the shoulder forms coupling or fixing elements for the jacket-like outer part, since this ensures that the jacket-like outer part does not have to be additionally fixed with, for example, an adhesive on the packaging container, but can be held positively and detachably in this area.

The fact that a cone angle of the shell is greater than 4 °, in particular greater than 5.5 °, the advantage is achieved that can be stacked space saving by this large opening angle of the packaging container.

According to one embodiment, it is provided that the jacket is at least substantially cylindrical, whereby the manufacturing process and the printing is simplified.

Another advantage is that the packaging container is formed from a plastic film, whereby a cost-effective production of the container is possible.

According to one embodiment, it is provided that the material for forming the plastic film from the group of polypropylene (PP), polystyrene (PS) or polyesters is selected, whereby the advantage is achieved that in addition to the low material costs a simple processability and good performance characteristics are ensured ,

It is also possible that the wall thickness of the packaging container in the region of the shell is between 10% and 40%, in particular between 15% and 30% of the wall thickness in the region of the reinforcement region, since a higher strength is achieved by the stiffening shaping and thereby saves material and thus costs can be reduced.

It is also advantageous if the reinforcing region has a plurality of radially extending grooves distributed over its circumference, with a depth which is at least twice the wall thickness, preferably at least three times the wall thickness, since an additional reinforcing or stiffening effect of the packaging container is thereby achieved ,

According to one embodiment, it is possible that the closure element is formed by a sealing flange, whereby it is possible in a simple manner to securely close the packaging container by means of a seal.

According to one embodiment, it is also possible that the closure element is formed by a thread, whereby the advantage is achieved that after removal of the contents or parts thereof, a simple resealing is possible.

The invention further includes the use of the packaging container for receiving, for example, dairy products, in particular yoghurt and other accessories, such as spoons or gifts.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

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

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

In the region of the first end region 3, a reinforcing region 8 extending over at least 50% of the circumference of the packaging container 1 is arranged, which forms a transition between the jacket 2 and the bottom 4 of the packaging container 1. The reinforcing portion 8 has a convex curvature 9 with respect to the outer surface of the skirt 2 or the bottom 4. The shape of the curvature 9 can, as in Fig. 1 illustrated, be formed, but may also have the shape of a quarter circle, ie the curvature runs on the side of the reinforcing region 8 which is the jacket 2, adjacent, approximately parallel to a central longitudinal axis 10 of the packaging container 1 and at the bottom 4 closer lying side of the gain region 8 almost in the direction perpendicular to the central longitudinal axis 10. The advantage here is that the footprint of the packaging container 1, while maintaining high strength, is maintained.

Curvature 9 has approximately 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, between these two regions.

The curvature 9 can also be composed of a plurality of "partial curvatures" such that curvatures of different radii of curvature 11 adjoin one another and thus obtain an optimum shape for the respective application.

If the closure element 7 is formed by a circumferential, planar sealing flange, it becomes possible, according to the methods known from the prior art, to close the packaging container with a sealing film, preferably a metal foil. By a corresponding design of the closure element 7, for example by a circumferential curved flange or a circumferential bead, it is further possible to have elastically deformable lid, for example made of plastic, snap fit over the closure member 7 so as to provide a resealable packaging container 1.

Such packaging containers 1 are often stacked in the empty state for the purpose of transport. In the case of embodiments which are known from the prior art, damage may be caused in the region of the first end region 3, due to the high weight caused by the stacking or due to the relatively sharp curves and edges, or may result in buckling and deformation of the packaging container 1 come. Due to the inventive design of the packaging container 1, such damage is reduced and more containers can be stacked without damage due to the higher strength.

The arrangement of the reinforcing region 8 further facilitates access to the contents or the removal of the contents of the packaging container 1. Since the radius of curvature 11 in the packaging container 1 known from the prior art or cups very much small or the transition from the jacket area in the bottom area is very sharp-edged, a complete or nearly complete removal of the contents was difficult durchzufiihren and a tedious "scraping" with, for example, a spoon needed. The inventive design, the removal of the content can be substantially facilitated if the curvature 9 or at least parts of the curvature 9 is adapted to that of a conventional spoon, in particular teaspoon.

It also proves to be advantageous if the radius of curvature 11 I or the radius of an enveloping circle is greater than 6 mm, in particular greater than 8 mm. This ensures that, if larger spoons are used than, for example, common teaspoons, it is easy to remove the goods or the residual material.

Furthermore, this embodiment leads to an increase in strength or stiffening in these areas, as a result of which the handling, especially during filling or later use, becomes more secure and buckling during stacking is also prevented.

The jacket 2 can also be provided between the first end portion 3 and the second end portion 5 at least partially by grooves or ribs in the direction of the central longitudinal axis 10, which are distributed along the circumference, which have the advantage of additional reinforcement and better orientation or Fixing the situation when stacking the packaging container 1 offers (in Fig. 1 not shown).

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

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

According to the invention, a radius difference 12 between a maximum radius 51 of the reinforcement region 8 and a radius 52 of the jacket region directly adjacent thereto is 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 perpendicular measured with respect to the central longitudinal axis 10. According to the invention, it is also possible for this radius difference 12 to be 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, whereby no or only a 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 reinforcement region 8 may be larger 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 is formed in the second end portion 5 approximately cylindrical or konterkonisch that the largest radius 51 of the gain region 8 is smaller than the radius 52 of the directly adjacent shell region 2. This causes the transition of the arranged in the second end region 5 shell 2 softens the conical jacket and prevents or reduces a catch of residual and thus facilitates the removal of the contents.

In addition, by means of the reinforcing region 8 arranged in the second end region 5, a structural reinforcement of the packaging container 1 or a deformation during the lifting of the container by a user is reduced.

The packaging container 1 has, in the first end region 3, the reinforcement region 8 with a curvature 9. This curvature 9 of the reinforcing region 8 has a radius of curvature 11 with respect to a cutting plane contained in the central longitudinal axis 10, which radius of curvature may be different at different points in the curvature 9. As already stated, the curvature 9 can take on any convex shape, such as the shape of a quarter circle. However, the curvature 9 can also have other convex curvature forms and, for example, be formed by an elliptical section. It is particularly advantageous if tangents to surface points of an inner side 53 of the packaging container 1 show a steady, non-erratic course of their inclination during the transition from the bottom 4 into the reinforcement region 8 or from the reinforcement region 8 into the jacket 2. In the transition regions between the bottom 4 and the reinforcing region 8 or between the reinforcing region 8 and the sheath 2 no edges or pointed throats are present on the inside 53 in this case.

According to the invention, it is further possible for a wall thickness 54 of the packaging container 1 in the region of the jacket 2 to be between 10% and 40%, in particular between 15% and 30%, of a wall thickness 55 in the region of the reinforcement region 8 (in FIG Fig. 2 indicated by the hatched area). This offers the advantage of a material saving and thus lower production costs. The necessary structural strength is nevertheless given since an increase in the strength is achieved on account of the reinforcement regions 8 or closing element 7 arranged in the first end region 3 or in the second end region 5.

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

The material for forming the plastic film may 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 authenticity, a relatively uncomplicated processing.

Polypropylene packaging containers have good strength and rigidity at low density, while having good stress cracking resistance. They retain their properties even at higher temperatures, whereby a packaging of warm material or heating of the content in the packaging container 1 according to the invention is possible.

Polystyrene in its basic form is clear-sighted with high rigidity and hardness. However, it is also possible according to the invention to color the material in order to adapt the appearance of the packaging container to the respective requirements. Due to the high strength, the use of these materials makes it possible to reduce the wall thicknesses of the packaging container to a minimum, which not only reduces costs but also reduces weight and thus brings advantages, inter alia, during transport of the containers.

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

It should be noted at this point that individual components of the individual variants are transferable to the other alternative embodiments, e.g. the arrangement of reinforcing regions 8 or the arrangement or formation of openings on the packaging container 1 or training with rectangular or triangular cross-section or cylindrical or counter-conical shapes, so that these parts of description are transferable accordingly, even if not explicitly taken in the individual embodiments thereof reference ,

According to the invention, it is possible for a second opening 15 or a first weakened area 16 designed to produce a second opening 15 to be arranged in the region of the jacket 2 of the packaging container 1. By such a configuration, it is possible according to the invention not only to gain access to the contents of the packaging container 1 through a first opening 6, but also, if necessary, to remove the contents through this second opening 15. The production of the second opening 15 can already take place during the actual forming process of the packaging container 1, for example by arranging gaps 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, to prevent the unwanted falling out of the content or the view of the content, it is possible according to the invention to form the second opening 15 initially closed. This can be done for example by a seal with a foil or a punch along a line of weakness in the weakened region 16. If necessary, access to the content can be released by tearing open or tearing off a first weakening region 16.

According to the invention, the second opening 15 or the weakening area 16 forming this opening can extend between the reinforcing area 8 arranged in the first end area 3 and the reinforcing area 8 arranged in the second end area 5. Furthermore, according to the invention, the extent of the second opening 15 or of the weakened region 16 in the circumferential direction can be up to 120 °. Thus, it is advantageously possible, the second opening 15 and the weakening region 16 optimally to the respective contents of the Packaging container 1 adapt. Also, the shape of the second opening 15 and the weakening area 16 is not on the Fig. 3 Rectangular shape shown to be limited, but are erfindungemäß, as shown in the 4 and 5 is shown, even circular or oval shapes or polygons as training the second opening 15 possible. Also encompassed by the invention are complex shapes, such as the silhouette of objects or figures, in particular comic figures.

Fig. 6 shows the packaging container 1 according to the invention in a view along the central longitudinal axis 10 in a circular configuration. The bottom 4 or its contour in the region of the first end region 3 is not shown.

Shown is a receiving space 17 recessed in the region of the second opening 15 in the direction of the central longitudinal axis 10 of the packaging container 1.

The receiving space 17 can be mitgeformt already during the manufacture of the packaging container 1, but can also be formed, for example, for more complex forms of the receiving space 17 by prefabricated moldings and subsequently connected to the packaging container 1, for example, welded or glued, be. Since the receiving space 17 is only connected to the packaging container 1 immediately before filling, a high stack density is achieved, as a result of which high transport quantities and thus lower costs are achieved as a consequence.

Due to the design of the packaging container 1 with a receiving space 17, it is possible to integrate an additional content to be packaged separately from the remaining contents of the packaging container 1. The size of the receiving space 17 corresponds to the size of the second opening 15 and the first weakening region 16 (in Fig. 6 not shown). It is preferably provided that the recessed receiving space 17 adjoins the second opening 15 or the first weakening area 16. The shape of the receiving space 17 itself is in Fig. 6 shown as an example only approximately rectangular. However, it is inventively possible to form the receiving space 17 in any desired, adapted to the application form.

The outer contour of the packaging container 1 along the central longitudinal axis 10 can both be cylindrical and conically tapered or widening.

Fig. 7 shows the packaging container 1 according to the invention in a view along the central longitudinal axis 10 in a rectangular configuration.

In this embodiment, the contour of the shell 2 of the packaging container 1 is designed rectangular. The predominantly rectangular receiving space 17 is arranged in one of the corners of the packaging container 1. Access to the receiving space via the second opening 15. The corners of the packaging container 1 and the receiving space 17 can also be rounded according to the invention. Likewise, the cross sections of the packaging container 1 and the receiving space 17 may be square.

According to the invention, the receiving space 17 can extend along the central longitudinal axis 10 between the reinforcement area 8 arranged in the first end area 3 and the reinforcement area 8 arranged in the second end area 5 (in FIG Fig. 7 not visible). In this case, the receiving space 7 can be arranged both in the lower, first end region 3 and in the upper, second end region 5. Preferably, the receiving space 17 in the region of the jacket 2 in an area with the thinner than the wall thickness 55 wall thickness 54 (see Fig. 2 ) arranged.

The outer contour of the packaging container 1 along the central longitudinal axis 10 may be both rectangular or square and conically tapered or widening. That the jacket 2 of the packaging container 1 is preferably conical, with the jacket 2 facing upwards, i. in the direction of the first opening 6, expanded.

Other possible embodiments of the outer contours of the packaging container 1 show FIGS. 8 and 9 ,

In Fig. 8 the packaging container 1 is approximately elliptical or oval.

If the shape of the packaging container 1 is further formed in the direction of a narrow ellipse (boat shape), this has the advantage that this shape of the human hand when gripping and holding the container even better ergonomically adapted is and thus a secure grip while maintaining a comfortable hold is given.

The receiving space 17 may be arranged, for example, on the longitudinal side and formed in cross section in the form of a half ellipse.

Fig. 9 shows the packaging container 1 according to the invention in a triangular configuration.

The semicircular receiving space 17 is located on one of the sides of the triangle.

An advantage of this embodiment is a simplified emptying process through the formation of a "gutter" through the acute angle of two adjacent triangular sides of the packaging container 1.

Fig. 10 shows a further embodiment of the packaging container 1 according to the invention, in perspective view.

Shown is in the region of the bottom 4 a set back in the direction of the central longitudinal axis 10 of the packaging container 1, adjacent to the second opening 15 receiving space 17. However, it is erfindungemäß also possible that in the region of the bottom 4, a weakening region is arranged, which after its removal Access to the receiving space 17 allows. In the receiving space 17, an identification feature, such as a label with attached barcode or similar codes or other support elements for a code, can be arranged.

Furthermore, it is also possible to attach the barcode, for example, directly to a wall bounding the receiving space 17, for example by means of an offset printing process or by embossing or depressions in the container wall itself. In the case of the attachment of a label, it is possible according to the invention to fix it to the packaging container 1 by, for example, a hot pressing process or by means of an ultrasonic welding process or a wide variety of adhesives or adhesives suitable for secure adhesion.

In the region of the first end region 3 and / or in the region of the second end region 5 can one or more reinforcing regions 8 may be arranged. The shoulders of the reinforcing regions 8 form coupling elements 14 for fixing a jacket-like outer part 18. The outer part 18 is wrapped around the jacket 2 of the packaging container 1 in the form of a sleeve or sleeve. The outer part 18 may for example be made of a cardboard strip.

Further shows Fig. 10 a shell-like outer part 18 surrounding the packaging container 1 and located between the region of the reinforcing region 8 in the region of the first end region 3 and the region of the reinforcing region 8 in the region of the second end region 5.

The shell-like outer part 18 assumes the function of a support jacket and gives the packaging container in the region of the shell 2 a high stability.

According to one embodiment of the invention, a further opening 19 or a further weakening area 20 designed to produce a further opening 19 can be arranged in the shell-like outer part 18. The further opening 19 may be reclosable. This can be done for example by a protruding tab 21 which can be clamped between the shell-like outer part 18 and the jacket 2 of the packaging container 1. It is also possible a glue point at the location of the outer shell-like part which is covered by the tab 21.

Furthermore, behind the region of the further weakened region 20 or behind the further opening 19, a receiving space 17 with a second opening 15 can be arranged (in FIG Fig. 10 not shown, see Fig.6 - 9 ). The further opening 19 can according to the invention have the same size as the underlying second opening 15, which allows access to the receiving space 17. It is also possible that the receiving space 17 is formed by corresponding wall parts of the shell-like outer part 18. In the embodiment of the jacket-like outer part 18 made of a plastic material, for example in the form of a bag, the advantage of a cost-effective manufacturing process is achieved because, for example, an additional content is integrated in the bag of the shell-like outer part 18, the bag, for example, sealed with a seal, and the shell-like outer part 18 is arranged around the packaging container 1, that the bag is arranged in or behind the second opening 15.

The shell-like outer part 18 may be formed according to the invention by a cardboard material. By forming fixing or coupling elements 14 through the reinforcement region 8 in the region of the first end region 3 and the reinforcement region 8 in the region of the second end region 5, it is possible according to the invention to fix the jacket-like outer part 18 to the packaging container 1. Special advantages of the shell-like outer part 18 when no adhesive or the like must be used by the coupling elements 14, since it is rotatable about the central longitudinal axis 10 of the packaging container 1 and can form a resealable closure element 7 for a receiving space 17. This is advantageous if an attached over the receiving space 17 tamper-evident seal, such as a sealing film, after first use has already been removed, since thus a simple re-closing by rotating the shell-like outer part 18 is possible.

By rotating the shell-like outer part 18, furthermore, the entire information or images, for example instructions for use, arranged over the circumference of the packaging container 1 can be made visible. The shape of the further opening 19 is not according to the invention on the Fig. 10 shown limited form. For example, rectangular or more complex geometric shapes or silhouettes of figures, in particular comic figures, may be formed. Furthermore, it is possible for the further weakened area 20 to form detachable elements which form, for example, elements of a puzzle.

According to the invention, the reinforcing regions 8 need not be restricted to the region of the first end region 3 or of the second end region 5, but a plurality of reinforcing regions 8 can be distributed over the entire jacket 2 of the packaging container 1. Accordingly, a plurality of shell-like outer parts 18 may be arranged between the respective reinforcing regions 8. It is also possible for the closure element 7, in particular a sealing flange, to form the coupling element 14.

According to the invention, it is possible that the packaging container 1 is printed directly in the region of the jacket 2, for example with an offset printing method, whereby it is possible to make this information or images visible through the further opening 19.

The height of the further weakening region 20 or the further opening 19 can extend to up to 95% of the jacket-like outer part 18, whereas the width of the further opening 19 or of the further weakened region 20 can extend up to 50% of the circumference.

It is also possible that the shell-like outer part 18 consists of a plastic material, wherein the fixing of this outer part in the region of the first end portion 3 by a arranged in this area reinforcing region 8 or by the closure member 7 can take place or a plastic hose over the desired area of the packaging container 1 is pushed and eg can be shrunk under heat.

As a material for the shell-like outer part 18, as already stated, cardboard but also plastic can be used. In particular, it is also possible to use a composite material which is composed of several layers of different materials, such as cardboard, plastic, but also metal foils. In the case of using a cardboard material is provided to provide the corresponding outer part 18 with a water-repellent layer. This can e.g. by using a laminated with a plastic film cardboard strip, which is tailored to take place. It can also be provided in particular that the cardboard is additionally sealed in the region of the cut edges with a water-repellent material. This is particularly advantageous when the packaging container 1 are exposed to increased moisture access. The coating of the cardboard used for the outer part 18 with a water-repellent layer is namely prevented that one of the moist environment to swelling of the carton and finally comes to a detachment from the jacket 2 of the packaging container 1.

Furthermore, it is possible to arrange a further shell-like outer part between the casing 2 of the packaging container 1 and the shell-like outer part 18, so that by turning the shell-like outer part 18 and thus the further opening 19 and the further weakening region 20, the further shell-like outer part or its Printing is visible.

Characterized in that a plurality of reinforcing regions 8 over the height of the packaging container. 1 can be arranged distributed, it is also possible to arrange a plurality of shell-like outer parts 18 and also several other shell-like outer parts with different colors or imprints and a plurality of each of these areas associated openings or weakening areas.

The holder of the shell-like outer part 18 is effected by the coupling elements 14 positively and releasably. The further shell-like outer part can according to the invention be permanently attached, in particular by an adhesive, to the shell 2 of the packaging container 1.

The conicity of the cup or the cone angle of the shell 2 may be greater than 4 °, in particular greater than 5.5 °, but may in particular in the second end portion 5 cylindrical or slightly konterkonisch, since thereby the manufacturing or filling process by an improved handling or recording in the filling station is simplified.

Fig. 11 shows a variant of the further opening 19 and the further weakening region 20, in a rectangular configuration.

The further opening 19 may extend over more than 50% of the height of the packaging container 1. It is again possible that a same size receiving space 17 is arranged for receiving an additional content. Otherwise, the under Fig. 10 described.

Shown is the jacket 2 of the packaging container 1 in a section perpendicular to its central longitudinal axis 10. The shell-like outer part 18 surrounds the jacket 2 of the packaging container 1. The further opening 19 is limited by the further weakening region 20, wherein the further weakening region 20 may be formed by a perforation, for example, and the further opening 19 is released by severing the perforation. It is also possible that the perforation is interrupted at least over parts of the further weakened area, so that the further opening 19 remains after severing the remaining perforation on the jacket-like outer part and is thus reclosable. In order to fix the further opening 19 in the closed state, the tab 21 is arranged, which can be clamped, for example, between the jacket 2 and the jacket-like outer part 18.

The shell-like outer part 18 may be formed entirely from a cardboard material. However, it is also possible that the further opening 19 made of a plastic material, in particular of a transparent plastic material and the remaining part of the shell-like outer part 18 is formed from a cardboard material. The plastic material can be connected by, for example gluing or welding with the cardboard material.

The access to the packaging container 1 or to a receiving space 17 (in Fig. 12 not shown) takes place by means of the second opening 15 or by severing the first weakening region 16.

The weakened region 16 can be formed by a perforation along its weakening line or by a seal which is applied, for example, by an adhesive, in particular by a hot-melt adhesive.

In the region of the second end region 5, a further reinforcing region 8 is arranged. Fixing or coupling elements 14 for holding a jacket-like outer part 18 are formed by the reinforcing regions 8 in the region of the first and second end regions 3, 5.

The second end region 5 can be provided with a closure element 7, in particular a screw thread or a snap closure, with a closure element radius 13. As a result, a repeated removal or a safe resealing of the content is easily possible.

According to the invention, the closure element radius 13 may also be smaller than the radius in the jacket region, for example of the order of magnitude of commercial drinking bottles.

However, the closure element 7 can also be designed as a sealing flange, if a multiple closure of the packaging container is not required in a specific application.

In the region between the closure element 7 and the reinforcement region 8 in the region of the first end region 3, at least one second opening 15 can be arranged with a receiving space 17 recessed in the direction of the central longitudinal axis 10. The special form of the receiving space should not be on the in Fig. 16 be limited shown shape, but are also deviating from the rectangular shape forms possible, as has been described in the preceding figures.

Furthermore, it is possible in the region of the bottom 4 to arrange a second opening 15 with a recessed along the central longitudinal axis 10 receiving space 17, which may be closed, for example, by a peelable seal.

Based on Fig. 17 and 18 In the following, another embodiment of a packaging container 1 with a receiving space 17 will be described.

The Fig. 17 shows a packaging container 1 with a receiving space 17 in side view, shown partially in section. The receiving space 17 extends from a region of the shell 2 to the bottom 4 of the packaging container 1. With the exception of the area of the receiving space 17, the outer shape of the packaging container 1 is rotationally symmetrical. The receiving space 17 is closed by a cover 56. This cover 56 is shaped so that it is complementary to the other, with respect to the central longitudinal axis 10 rotationally symmetrical shape of the packaging container 1 is formed and in the patch, the receiving space 17 occluding state the packaging container 1 a total of a rotationally symmetrical shape. The shape of the receiving space 17 or the shape of a top wall 57 and a side wall 58 are designed so that a plurality of packaging container 1 can be nested without patch cover 56 and thus stacked. The transition region between the side wall 58 and the bottom 4 of the packaging container 1 is formed with a radius of curvature 59. Likewise, the transition region between the top wall 57 of the receiving space 17 and the jacket 2 is formed with a radius of curvature 60. Likewise, as already stated for the radius of curvature 11, it is also provided for these radii of curvature 59 and 60 that they are greater than 6 mm, in particular greater than 8 mm. As a result, as already with the radius of curvature 11, the advantage is achieved that in this area adhering content of the packaging container 1 with conventional spoons or a teaspoon can be easily removed.

However, the design of a stackable packaging container 1 having a cover 56 formed in the manner described above to be complementary to the outer shape of the packaging container 1 is not limited to a rotationally symmetrical outer shape but may be applied to packaging containers 1 having other cross sections.

The Fig. 18 shows a cross section of the packaging container 1 according to Fig. 17 , The recessed in the direction of the central longitudinal axis 10 of the packaging container 1 receiving space 17 is bounded on the one hand by a continuation of the jacket 2 formed from a part of the shell 2 side wall 58 and on the other hand by the cover 56. The transition regions between the center longitudinal axis 10 of the shell. 2 Concentric region and the side wall 58 are formed with a radius of curvature 61. Also for the values of the radii of curvature 61 apply the statements already made, as for the radii of curvature 11, 59 and 60. The connection of the cover 56 with the packaging container 1 can be done for example by gluing. But between the cover 56 and the jacket 2 of the packaging container 1 can also be formed, for example, a snap connection, so that the receiving space 17 can be reversibly opened and closed again. Due to the configuration of the packaging container 1 and the cover 56 according to this embodiment is achieved in an advantageous manner that the empty packaging container 1 can be nested or stacked and on the other hand is ensured by the formation of the cover 56 that the filled and sealed packaging container 1 via has sufficient stability.
