Description

container

The present invention relates to a container having a container vertical axis and a side wall, which is closed at the bottom with a bottom and above an opening, wherein the container is made of at least one blank.

Furthermore, the present invention relates to a container, primarily with an axis and in particular a rotationally symmetrical shape, with a side wall which is closed at the bottom with a bottom and above an opening, wherein the container is made of at least one blank.

Furthermore, the invention relates to a container with a frusto-conical shape, wherein a side wall is closed at the bottom with an inserted bottom and above an opening with an outwardly directed mouth roll, wherein the container is made of at least one carton blank.

Furthermore, the invention relates to a tool for producing a container according to the present invention.

Containers for holding pourable products and liquids are known in practice. These containers have a container vertical axis or have primarily an axis or rotationally symmetrical shape, are made of at least one blank and have a side wall which is closed at the bottom with a bottom. Opposite the bottom, the side wall above defines an opening. This opening can be formed in many ways and, for example, have a rolled edge. This edge can also serve to receive a lid for closing the container. Different products in different consistencies can be filled into the container and kept in it permanently. Likewise, the container is usable without the lid. A consumer can grasp and remove the products in the container through the opening. It is also possible to pour the products by pivoting the container over the opening and the adjacent edge. The filling level of the container is limited over the entire container cross section by the opening arranged parallel to the bottom surface. For example, when the container is stored in a supermarket shelf at a height equal to a consumer's eye level, it can not look into the container due to the opening parallel to the bottom surface of the container, but only sees the outer peripheral surface of the container.

Containers with an oblique upper termination of the opening are known. The document DE 3329533 A1 shows a container with an obliquely arranged opening, wherein the container ^"is not formed from a blank but is produced from a plastic by deep-drawing process." Thus, this document is to be classified in a different genre, since with a deep-drawing method only containers made of plastic and not desired in practice container made of cardboard can be produced.

Object of the present invention is to develop a manufactured from a blank container according to the type mentioned in such a way that the product removal from the container and the insight into the container interior is made more user-friendly and at the same time a cost-effective production of the container is possible, especially without injection molding technology.

In addition, a suitable tool for producing a corresponding container should also be provided.

This object is achieved according to the invention with a container having the features of claim 1. As explained above, the opening in conventional containers, which are made of a blank, arranged parallel to the bottom surface of the container. From this concept, the present invention is fundamentally different in that it obliquely arranges the opening and / or the bottom with respect to a container vertical axis, so that a distance between the opening edge and the bottom varies over the circumference. This oblique arrangement of the upper container area allows a consumer to easily look into the interior of an eye-level container and visually detect the contents of the cup without touching the container.

Due to the obliquely arranged opening, the filling height of the container is limited to the point of the edge of the opening which is closest to the bottom of the container. The upper point created by the oblique arrangement of the edge, the farthest from the Bottom of the container is located, includes at the periphery of the container inside between itself and the lower point of the container edge, a visible surface in which no products are received in the container interior. Surprisingly, an additional printable area, which can be used, for example, as an advertising space to create an additional buying incentive, thus surprisingly results in this viewing area.

Furthermore, the product removal from the container is improved by the obliquely arranged opening.

The above object is further achieved according to the invention with a container having the features of claim 2. The opening and / or the bottom of the container having a predominantly axis-shaped and in particular a rotationally symmetrical shape, is inclined to a container vertical axis, in particular a rotation axis, at an angle. This oblique arrangement also results in an area in the container interior, which allows insight even when placed parallel to the eye level of the consumer container. The oblique arrangement of the removal area also improves the user-friendliness. Since the container is made of at least one blank, both the material costs and the manufacturing costs are minimized.

A particularly advantageous embodiment of the invention provides that the container is a rotationally symmetrical body, such as a truncated cone. As a result, the container tapers from the opening to the bottom and allows easy grasping on the container outside by the hand of a consumer.

It is conceivable that the container is a point-symmetrical body, for example, has a square or rectangular or polygonal cross-section. As a result, a wide variety of requirements for the container shape are executable.

Furthermore, the container may be a multi-axis body, e.g. has an elliptical cross-section.

The container may be circular in cross-section, quadrilateral, such as square, oval, elliptical or polygonal, to accommodate any desired container design. Advantageously, the container is stackable to be able to store it even in a small storage room in large quantities. Especially by the frusto-conical shape of the container this is easily stackable.

It has proved to be very advantageous that the bottom for the container consists of a bottom insert which is connected to the side wall. Thus, in addition to a quick joining process, a special tightness of the container can be achieved.

If the bottom insert is made from a separate blank, a variety of materials can be used for this, which may also differ from the sidewall material.

The bottom has a shape dependent on the container cross-sectional shape, and thus is round in a frusto-conical container. If the bottom is arranged obliquely to the container axis, it has an oval shape.

Advantageously, the shape of the opening corresponds approximately to the shape of the floor. If the bottom has a round shape, and the opening also has a round shape, the container is particularly easy and quick to produce.

In an advantageous embodiment of the invention, the area of the opening may be larger than the area of the floor, thus allowing a comfortable engagement of a user in the container interior.

Various variations of the container shape are conceivable for design purposes. For example, the shape of the opening cross section may be round and the shape of the bottom cross section may be polygonal.

In an advantageous embodiment of the invention, the opening may have an outwardly projecting outer edge flange which at least partially surrounds the opening. This outer rim flange improves not only the design of the container but also its dimensional stability and ease of use. The outer edge flange may be formed as a bent, folded or rolled-up mouth roll, thus protecting the user or consumer from possible injury from a sharp-edged container edge.

It is advantageous if the opening has a closure, such as a transparent cover, so that a consumer can view the goods located in the container, but this is at the same time hygienically packed.

On the other hand, the container may also have a tamper-proof lid, which is transparent, for example, to thus on the one hand to securely close the container and on the other hand to allow the insight into the container interior.

The container vertical axis may be a rotationally symmetrical axis, for example a cylindrical or conical container.

On the other hand, the container vertical axis can also be a point-symmetrical axis, for example of a square container.

Furthermore, the container may also have a plurality of container high axes, for example in an elliptical container shape.

In a preferred embodiment of the present invention, the angle between the aperture and the container vertical axis is about 70 ° to 88 ° and preferably 80 °. The angle of about 88 ° is particularly suitable for drinking vessels. An angle of 70 ° can cause a particularly large presentation area between the filling level of the container and the uppermost container edge and thus make the container for candies, chocolate, biscuits and the like appear particularly suitable.

The opening and / or the floor can also have different shapes. The tangents are then arranged at different angles to the container vertical axis, thus forming a variable plane or an opening with a concave surface. It is particularly favorable if the inside of the container has a printable surface which allows a special design, such as advertising, product or user information.

In a particularly advantageous embodiment of the present invention, the container has a frusto-conical shape, wherein a side wall is closed at the bottom with an inserted bottom and above an opening with an outwardly directed mouth roll, wherein the container is made of at least one carton blank and the opening is arranged obliquely to a container axis at an angle of 76 ° to 83 °. In this embodiment, the simple but effective container shape can be combined with a consumer-friendly designed opening and manufactured in a cost effective process.

Advantageously, the blank for the container made of paper, cardboard or similar cuttable, dimensionally stable material. This cost-effective and environmentally friendly material and the simple and fast production of a container made of this material allows the realization of very low production costs for the container. At the same time the container is sufficiently stable.

The object mentioned above is further achieved with a tool having the features of claim 26.

The tool consists of a punch and a die. The die may have a tool face inclined to a rotational axis of the tool at an angle to form an outer peripheral flange at an opening of the container. As a result, the tool according to the invention can be used for cost-effective production of the container in a production method known from practice.

The tool also includes a die having a portion complementary to the tool face of the punch for forming a mouth roll. With this tool design, it is possible to produce the mouth roll also at an obliquely arranged opening. Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In detail show:

The invention relates to a container 1 for receiving liquid or pourable products. Such containers are known in the art and are commonly used to hold food and drink.

The first embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3.

The container 1 has a container vertical axis 5 and a tapered shape. The container 1 has a side wall 2, which is closed at the bottom with a round bottom 3. At the top, the side wall 2 defines a round opening 4. The container 1 consists of a two-dimensional blank 10. The opening 4 in the container 1 shown in FIG. 1 is arranged obliquely with respect to a container vertical axis 5 at an angle α. The container vertical axis 5 is perpendicular to the bottom 3. The container 1 has the shape of a truncated cone with a slope ß, which tapers from the opening 4 to the bottom 3 from top to bottom. The side wall is closed at the bottom with a bottom 3, which consists of a bottom insert 6, as shown in FIG. The geometric construction of this container 1 is shown in FIG. 8.

Due to the obliquely arranged opening of the container, the side wall 2 has different distances between the opening edge and the bottom over the circumference. Furthermore, the side wall 2 in the lower region of the container 1 on a circumferential folded-over area, in which the bottom insert 6 is inserted. The side wall 2 has a dimensionally stable stiffness, which is achieved due to the container material, the frusto-conical shape, the shape of the opening 4 and the bottom 3. The side wall 2 is at least partially coated. The side wall surface directed towards the container interior consists of a food-safe material. Both the inside and the outside of the side wall 2 is provided with an imprint, which is already applied to the blank 10 before the shaping process.

The container is formed of a two-dimensional blank 10 in the shape of a truncated cone with the inclination angle ß. Along the lateral surface of the truncated cone of the container 1 is overlapping firmly connected to itself, preferably glued. The design of the Container 1 in the form of a truncated cone allows the container 1 is stackable. The material of the blank 10 is paper and printing on both sides and coatable. The combination of material and shape of the container provides a particularly good haptic property of the container. 1

The material of the bottom insert 6 corresponds to the material of the container 1. The directed to the container interior surface of the bottom insert 6 is made of a food-safe material. The bottom insert 6 is made of a separate blank and has a surface with a circumferential flange. This flange of the bottom insert 6 connects to the inner surface of the side wall of the container and thus provides a closed container bottom, which is also fluid-tight. The bottom 3 and thus also the bottom insert 6 is dependent on the container cross-sectional shape in the area to be introduced. Thus, the bottom 3 is round when the container 1 has a round container cross-sectional shape in the area provided for the bottom 3.

As shown in Fig. 1, in the first embodiment of the present invention, the opening 4 is arranged at an angle α obliquely to the container vertical axis 5. The angle α is greater than the inclination angle ß. The shape of the opening 4 corresponds to the shape of the bottom 3, so that the container 1 has a round cross-sectional shape both in the upper and in the lower region. Since the opening 4 is arranged obliquely, results in the plan view, see Fig. 3, an oval contour for the circular opening cross-section. The area of the opening 4 is larger than the area of the bottom 3. Due to the oblique arrangement of the opening 4 with respect to the container axis 5, the distance between the opening edge and the bottom varies over the circumference of the container first

In Fig. 1, two opposite points P1 and P2 are shown at the edge of the opening. The point defined by P1 on the outer edge flange 7 has a smaller distance to the bottom 3 of the container 1, as a diametrically arranged to the point 1 and denoted by P2 point on the outer edge flange 7. The height difference between the points P1 and P2 is given by the angle α and the distance between the points P1 and P2. During the filling process, liquids are filled into the container 1 only up to the point P1. No liquid is introduced into the remaining container volume between the points P1 and P2. This results in a container inner surface 9 in this area, which is not covered by products. This area 9 will be the ren color design, for consumer information and used as advertising space. Even with pourable products, a degree of filling up to the point P1 or the point P2 is possible.

Fig. 2 shows the front view of a container shown in FIG. 1. The container is on the ground, so that by the oblique arrangement of the opening 4, a container inner side 9 is visible. For a consumer, this surface 9 is visible without having to lift the container. Furthermore, the oblique arrangement of the opening 4 also facilitates the removal of products from the container 1 with the fingers, or even the drinking of liquids from this container. 1

In Fig. 6 is an outwardly projecting Außenrandflansch 7 can be seen, which is designed as a rolled-up mouth roll 8 and the opening 4 edges. This mouth roll 8 prevents injuries that could result from a sharp-edged container closure. Furthermore, this Außenrandflansch 7 increases the stability of the entire container 1. On the outer edge flange 7, a closure is applied, which is for example a transparent cover or a tamper-evident, transparent lid. This closure prevents uncontrolled removal of products in the container 1 and at the same time guarantees a consumer that the container contents are intact.

Referring to Figs. 4 and 5, the second embodiment of the present invention will now be described in which a container 1 has the features as described above. However, the opening 4 is arranged perpendicular to the container vertical axis 5 and the bottom 3 is arranged in this embodiment at an angle α obliquely to the container vertical axis 5. When the frusto-conical container 1 is placed on the floor 3 inclined at an angle to the container vertical axis 5, the above-described points P1 and P2 at the outer edge flange 7 again result, which with respect to the floor 3 results in a varying distance of the opening edge from the floor 3. Thus, this inclined bottom embodiment 3 also provides an additional printable area on the inside of the container 9, which is visible during use of the container 1. The geometric construction of this container 1 is shown in FIG. 9. The container vertical axis 5 is perpendicular to the opening 4th

FIG. 7 shows a two-dimensional blank 10 for the container 1 according to the invention, which is rolled and along the jacket surface of the resulting container 1 is glued. The lower portion of the blank 10 is formed as a radius, so that this area after rolling the blank 10, the round bottom 3 is formed. The upper wave-shaped region of the blank 10 limits the obliquely arranged opening 4 after the rolling process, as shown in FIG.

6, the tool 11 for producing the Außenrandflansches 7 at the opening 4 of the container 1 is shown. The tool 11 consists of a punch 12 and a die 13. The vertical axis of the punch 11 also corresponds to the vertical axis of the die 13, i. the punch 11 moves relative to the die 13. The structure of the punch 11 is known from practice. For the manufacture of the container 1 according to the invention, however, it has a tool surface 14 arranged obliquely to the vertical axis of the punch 12. The angle corresponds to the angle predetermined for the obliquely arranged opening 4 of the container 1. In addition, the punch 11 has a circumferential groove 15 which adjoins the tool surface 14.

The die 13 has a receiving area whose shape corresponds to the container shape. The rolled blank 10 is inserted into this die 13, so that the bottom 3 of the container 1 is flush with the die 13. The upper portion of the die 13 is formed obliquely to the vertical axis, so that the obliquely arranged opening 4 of the container 1 is aligned with this die 13. This area of the die 13 is formed complementary to the tool face 14 of the punch 12 and the circumferential groove 15 adjacent thereto. This tool 11 produces the mouth roll 8, which is circumferentially mounted on the opening 4 of the container 1.

After the rolled blank 10 is bonded and the bottom insert 6 is secured therein, the container 1 is inserted into the die 13. After the correct positioning with respect to the obliquely arranged opening 4 of the punch 11 is moved relative to the die 13, so that the upper hitherto unprocessed edge of the container 1 abuts against the punch 11 and in particular the groove 15. Due to the further relative movement of the punch 11 to the die 13, this upper edge of the container 1 is formed into a mouth roll 8. Fig. 6 shows the finished container 1 in the die 13 after the punch 11 is moved back again. In Figs. 10 and 11, the third embodiment of the present invention is shown. The container 1 consists of a blank 1O ₁ which is brought into a cone shape and glued. The bottom 3 extends along the container vertical axis 5 and an outer edge flange 7 surrounds the opening 4, which is arranged obliquely to the container vertical axis 5.

Figs. 11 and 12 show the fourth embodiment of the present invention. The container 1 has a conical shape and the opening 4 is arranged obliquely to the container vertical axis 5.

Starting from the illustrated embodiments, the invention can be modified in many ways. For example, the shape of the container can be changed so that square, rectangular or polygonal cross-sections are formed, which can also be arranged at different angles to each other. The container may also have an elliptical cross-sectional shape or be an asymmetrical body. The container 1 may also be made of a plastic material or a multilayer material. The connection of the blank to itself is made by heat and / or pressure.

The bottom insert may also be integrally connected to the side wall. A partial region of the opening can be flat and adjoin a region arranged obliquely to the container vertical axis.
