Description

2 AT 503 832 B1

The invention relates to a packaging container made of a deep-drawn cup-shaped plastic part, which has a thin-walled jacket, which is closed in the region of a first end region by a bottom and in the opposite second end region has a first opening, and in the bottom of a recessed in the direction of a central longitudinal axis receiving space is formed which is bounded by a footprint formed by the ground.

From DE 202 08 068 U1 a packaging and food bowl for food with at least one food utensil has become known. In the bottom area elevations are formed, between which the food utensil is located. At the outer ends of one or all elevations are adhesive surfaces, wherein the at least one eating utensil is enclosed with a cover attached to the surveys. The cover has at least one tab, with which it can be detached from the packaging or feeding bowl and thus the access to the food utensil is released.

From WO 02/12078 A1 a receptacle has become known in which in the region of the bottom in the container casing an additional receiving chamber separate from the receiving chamber is arranged, in which different products formed to the filling material to be received. To limit the additional receiving chamber and thus to prevent inadvertent loss or removal of these objects from this chamber, a cover is provided which covers a portion of the chamber. This regional coverage of the chamber can be formed by a pivotable angular element, a push-in and lockable L-shaped element (FIG. 3d) or a jacket-shaped element enveloping the container jacket at least in regions.

JP 2002 045 046 A describes one or more receiving pots for young plants, in which an insertion slot for a marking strip is formed in the region of the upper edge of the container. In the vicinity of the Einsteckschlitzes the container wall is set back in the direction of the receiving space of the plant pot to separate that portion of the identification strip which extends through the slot from the receiving space for the young plant. This avoids direct contact of the identification strip with the soil surrounding the young plant and thus creates an area for arranging the insertion slot in the region of the open end of the plant pot. The identification strip has corresponding latching projections in order to hold these in the slot. Another section of the identification strip protrudes beyond the open end of the pot in the side facing away from the ground and is thus easy to see without any manipulation of the pot.

From WO 98/13 270 A1 a combination packaging container known which comprises an inner cup-shaped plastic inner part and a pushed over the plastic inner part and the plastic inner part outside surrounding coat-like outer part. The plastic inner part has in the region of its container shell on an inwardly recessed form for receiving additional items between the plastic inner part and the outer part pushed over it. In order to be able to remove the additional object received in the recessing recess, an engagement opening is left free at the upper edge and / or lower edge of the jacket-shaped outer part. The additional object is a consumption aid for the contents taken up in the combination packaging container and may be formed by a drinking straw or a spoon.

The production of cup-shaped packaging containers made of plastic for receiving dairy products has long been known. In this case, 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, as well as sharp or formed by 3 AT 503 832 B1 small radii transitions from the conical area to the floor area.

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 invention has for its object to provide an improved identification of the packaging container.

The object is achieved in that in the receiving space formed by a label planar information carrier is recorded with an identification feature which is circumferentially positively held by undercuts in the receiving space and the information carrier is arranged distanced to the ground formed footprint and while the information carrier is almost completely visible ,

It is advantageous that when using a code this can be used to identify the packaging container in terms of its origin, date of manufacture, date of filling, content, price, durability, etc. If the receiving space for receiving accessories, such as gift items, toys for children, recipes, cards for raffles, scratch cards or items that serve to remove the contents of the packaging container formed, these are visible, for example, by upside down the packaging container or removable. At the same time, the information carrier also prevents the accessories from falling out.

If the receiving space is still closed by a peelable seal, so that a tamper-evident closure can be achieved.

An arrangement of a second opening or a weakening area formed in the region of the bottom for the purpose of producing a second opening is advantageous, since according to the invention it is 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 is the removal or facilitate access to the content, as for example, the possibility is created 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 this content to be separated from the rest of the content.

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.

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 the circumference of the packaging container 1 can be 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 may be formed as shown in Fig. 1, but may also have the shape of a quarter circle, i. the curvature runs on the side of the reinforcing region 8, which is adjacent to the jacket 2, approximately parallel to a central longitudinal axis 10 of the packaging container 1 and can extend almost perpendicular to the central longitudinal axis 10 on the side of the reinforcing region 8 closer to the bottom 4. The advantage here is that the footprint of the packaging container 1, while maintaining high strength, is maintained. 5 AT 503 832 B1

Between these two regions, the curvature 9 can have 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. 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, does not run parallel to the central longitudinal axis 10, but substantially in the direction towards the first opening 6 conically expanded.

Of course, 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 known from the prior art packaging container 1 or cups very small or the transition from the shell area in the bottom area is very sharp, a complete or nearly complete removal of the contents was difficult to perform and a tedious "scraping "With a spoon, for example. 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 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 provides (not shown in Fig. 1). 6 AT 503 832 B1

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

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 measured perpendicular 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 approximately cylindrically or counter-conically in the second end region 5, that the largest radius 51 of the reinforcing region 8 is smaller than the radius 52 of the directly adjacent jacket region 2. This results in 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 reinforcement 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 has already been stated, the curvature 9 can be any convex shape, e.g. also take the form of a quarter circle. However, the curvature 9 may also have other convex curvature shapes and e.g. also 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. 2 by the hatched area indicated). 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 injection-stretch blow molding, however, is also possible 7 AT 503 832 B1.

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 variant of the packaging container 1 according to the invention, with an additional weakening region 16 or a second opening 15 arranged in the region of the jacket 2.

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 weakened area 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 °. As a result, it is advantageously possible to optimally adapt the second opening 15 or the weakened area 16 to the respective content of the packaging container 1. Also, the shape of the second opening 15 and the 8 AT 503 832 B1

Weakening portion 16 not limited to the Fig. 3 shown rectangular shape, but are erfindungemäß, as shown in Figs. 4 and 5, also 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 (not shown in FIG. 6). 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 shown in Fig. 6 only by way of example 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 may be both 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 reinforcing area 8 arranged in the first end area 3 and the reinforcing area 8 arranged in the second end area 5 (not visible in FIG. 7). 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 is arranged in the region of the jacket 2 in a region with the wall thickness 54 thinner than the wall thickness 55 (see FIG. 2).

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.

Further possible embodiments of the outer contours of the packaging container 1 are shown in FIG. 8 and FIG. 9.

In Fig. 8, the packaging container 1 is formed 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 is even better ergonomically adapted and thus a secure hold at the same time pleasant feeling 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 a perspective view.

Shown is in the region of the bottom 4 in the direction of the central longitudinal axis 10 of the packaging container 1 rückversetzter, 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 delimiting 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, one or more reinforcement regions 8 can 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 e.g. be made of a cardboard strip.

10 shows a jacket-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. 1 0 AT 503 832 B1

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 weakening region 20 or behind the further opening 19, a receiving space 17 with a second opening 15 may be arranged (not shown in FIG. 10, see FIGS. 6-9). According to the invention, the further opening 19 can have the same size as the second opening 15 located behind it, 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 such that the small 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 a tamper-evident closure, for example a sealing foil, fitted over the receiving space 17 has already been removed after first use since a simple re-closing by rotating the jacket-like outer part 18 is thus 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 limited to the shape shown in FIG. 10 according to the invention. 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 weakening region 20 to form separable 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 wider opening 19 or the further weakening region 20 extends up to 50% of the scope can extend. 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 jacket 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 jacket-like outer part or its Printing is visible.

Due to the fact that a plurality of reinforcing regions 8 can be arranged distributed over the height of the packaging container 1, it is also possible to arrange a plurality of jacket-like outer parts 18 and also several further jacket-like outer parts with different colors or imprints and several openings or areas of weakness associated with each of these 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 embodiment of the further opening 19 or of the further weakening area 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, that described under FIG. 10 applies.

FIG. 12 shows the further opening 19 in section XII-XII of FIG. 11. 12 AT 503 832 B1

It should be understood that the embodiment described herein can of course be applied to other forms of packaging container 1, for example of rectangular or triangular cross-section or cylindrical or conical shape.

Sheath 2 of packaging container 1 is shown in a section perpendicular to its central longitudinal axis 10. Sheath-like outer part 18 surrounds sheath 2 of packaging container 1. The further opening 19 is delimited by the further weakened area 20, wherein the further weakened area 20 is formed by, for example, a perforation may be and by severing the perforation, the further opening 19 is released. 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 (not shown in FIG. 12) takes place by means of the second opening 15 or by severing the first weakened area 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.

FIG. 13 shows a variant embodiment of the reinforcement region 8 of the packaging container 1 according to the invention, with radially extending grooves 22 arranged in the reinforcement region 8.

These grooves 22 may be distributed distributed in the amplification area 8 at uniform intervals distributed over the circumference. They run radially with a depth or elevation which is at least twice the wall thickness, preferably at least three times the wall thickness. According to the invention, the grooves 22 can also run only over partial regions of the reinforcement region 8. In addition, a further reinforcement region 8 may be arranged in the second end region.

The survey or the depression results in an additional stiffening of the gain region, whereby loads when stacking several packaging container 1 can be better absorbed.

The bottom 4 is rounded by a curvature 9 with raised central region such that the radius of curvature 11 is more than 4 mm, preferably more than 6 mm, in particular more than 8 mm.

This can on the one hand be prevented that can catch residual material in sharp corners or the removal of the contents can be simplified, on the other hand, a further reinforcing effect of the bottom 2 is achieved.

Of course, it is also possible to arrange a further reinforcement region 8 in the region of the second end region 5. The description of this and the other embodiments can be taken from the corresponding points in the further description of the figures.

FIG. 14 shows a variant embodiment of the bottom region of the packaging container 1 according to the invention.

Shown is a section through the first end portion 3 of the packaging container 1. In the bottom 4, a receiving space 17 is formed, which can receive an information carrier 23, such as a label with attached thereto barcode or similar codes or other support elements for a code. The code can be used to identify the packaging container 1 in terms of its origin, date of manufacture, date of filling, contents, price, shelf life, etc. The label can be positively held by undercuts or adhesives.

Furthermore, it is also possible to attach the barcode, for example, directly to a wall delimiting the receiving space 17, for example by means of an offset printing process or by embossing or depressions in the container wall itself.

As shown in FIG. 14, in the region of the receiving space 17, a second opening 15, which is delimited by weakened areas 16, can also be formed. Thus, it is possible to remove the contents of the packaging container 1 through the opening 15 after removal of the information carrier 23, which covers the receiving space 17. In addition, it may also be provided that this opening 15 is protected by a tamper-evident closure such as this. a sealing film, is closed.

FIG. 15 shows a further embodiment variant of the bottom region of the packaging container 1 according to the invention.

Compared to FIG. 14, FIG. 15 shows a larger receiving space 17. The receiving space 17 can serve in addition to receiving the information carrier 23, for example, for receiving accessories 24, such as small gifts or toys for children or similar items. Also possible according to the invention are recipes, in particular preparation recipes, or also cards which are used for competitions, in particular scratch cards.

Also possible are contents that serve to remove the remaining contents of the packaging container, for example spoons, skewers or forks or similar objects.

According to the invention is also possible that the information carrier 23 is formed by, for example, a scratch card. At the same time, the information carrier 23 prevents the accessory 24 from falling out.

Of course, it is also possible to arrange a further reinforcement region 8 in the region of the second end region 5. The description of this and the other embodiments can be found in the corresponding parts of the further description of the figures.

FIG. 16 shows a further embodiment of the packaging container 1.

Shown is the packaging container 1 according to the invention with parallel to the central longitudinal axis 10 extending coat 2. The first end portion 3 is closed with a bottom 4 and a reinforcing region 8 is provided which forms a curvature 9, which has approximately a radius of curvature 11 and a radius of an enveloping circle, which is greater than 4 mm, preferably greater than 6 mm, in particular greater than 8 mm.

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 AT 503 832 B1.

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 specific shape of the receiving space should not be limited to the shape shown in FIG. 16, but shapes other than the rectangular shape are also possible, as 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.

According to the invention, a jacket-like outer part 18 can also be arranged in the region of the jacket 2 of the packaging container 1, as a result of which an additional stiffening effect can be achieved. In addition, a further opening 19 or a further weakening area 20 may be arranged which allows access to the contents of the receiving space 17. The shell-like outer part 18 is fixed by the coupling elements 14 in the axial direction and can thus be rotated in the tangential direction.

The shell-like outer part 18 may further be provided with a tear strip, whereby it can be separated from the packaging container 1 and also an access to the contents of the receiving space 17 is made possible (not shown in Fig. 16).

A further exemplary embodiment of a packaging container 1 having a receiving space 17 will be described below with reference to FIGS. 17 and 18.

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 without patch cover 56 nested and thus can be 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 has already been stated for the radius of curvature 11, it is also provided for these radii of curvature 59 and 60 to be 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 receiving space 17 recessed in the direction of the central longitudinal axis 10 of the packaging container 1 is bounded on the one hand by a side wall 58 formed in continuation of the jacket 2 from a part of the jacket 2 and on the other hand by the cover 56. The transition regions between the region concentric with the central longitudinal axis 10 of the jacket 2 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.
