Description

Container {CONTAINER}

The present invention relates to a container for holding food with a container wall comprising at least one paper layer and an additional layer. The container has a container opening at its upper end and is closed at a lower end opposite the container opening. At least the container wall is formed of a two-dimensional cut that is joined to form a continuous container wall. At least one inspection window is arranged on the vessel wall and is closed with a transparent or translucent window film.

Such containers are known as liquid containers in the form of cubes. Such a liquid container includes a flat sidewall formed by a window extending in the longitudinal direction of the container. This window is used to monitor the level of liquid filled in the container. The paper layer of such a container consists of a relatively rigid cardboard member and an additional fluid tight film or foil made of a resin member on its inner surface. The window is mainly made only in this relatively rigid layer and the inner surface of the container is closed by a corresponding liquid seal foil which is transparent or at least translucent.

Other cube shaped containers are known to be used to hold rice, noodles, flour, sugar and the like. These containers comprise a window that is generally closed from the inside by a foil that is glued in the window area to the flat sidewalls.

According to these known containers, the corresponding paper layer is always relatively rigid, in particular made of cardboard members. According to this paper layer, the container has a corresponding fold-by-fold bond to form a flat sidewall arranged at a relatively high strength in the circumferential direction simultaneously with the top and bottom surfaces. Window foils are used only for this combination to cover the corresponding window to prevent leakage of liquid or dry food through the window.

It is an object of the present invention to improve the container described above, and also by using very thin layers of paper, and because there is no other fold or fold line of the corresponding cup to form a three-dimensional container, such a window is maintained so that Sufficient stability may be shown. This object is solved by the features of claim 1.

According to the invention, this invention is characterized in that the container wall is at least partially curved in the window area. This curvature ensures increased rigidity and sufficient stability of the finished container. For further increase in stability at this connection, the window foil adhering the window is thermally bonded with the paper layer. This thermal bonding ensures wall curvature and additional stiffness of the container wall, and intimate connection between the window foil and the paper layer, finally providing more stability for the container.

According to a feature of the invention, such a window is also possible for a container with a very thin wall and the corresponding rigidity and stability of the container is sufficient to allow food to be taken out of the container opening.

In addition, by thermal bonding of the window foil and the window of the curved area of the container wall, the shape stability of the container also lasts at least in this area. Without the features of the present invention, such a container would not be sufficiently stable in shape without a filling to be simply filled, such as a container or stockpile.

The curvature of each container wall of a window area ensures stability in the longitudinal direction of a container similarly to sufficient stability in the circumferential direction.

According to the invention, it is already sufficient if the window foil is thermally bonded to the paper layer at least in the window edge region. This thermal bonding is carried out along at least all the edges of the window to sufficiently bond the window. Other types of fixing are possible between the window foil and the paper layer at the outside of the edge or at greater distances from the window.

Another layer is a metal layer, in particular an aluminum layer, in order to ensure a simple way in which the fluid is sealed to the gas or liquid in the paper layer, especially on its outer surface. These layers are simple to manufacture and secure to the paper layer. This metal layer is selectively covered on each outer surface of the paper layer. In addition to the metal layer, or alternatively, each inner surface of the paper layer may be covered with a resin layer as an additional layer. Such a resin layer is made of polyethylene, polypropylene, polyvinyl chloride, polystyrene, or other resin, for example.

Each additional layer is used for the purpose of the barrier used for each density, in particular taking into account gases and liquids. In addition, such metal layers are particularly useful for forming edges by forming in other ways to curl, fold or form opening edges. The metal layer can also support tear opening of the container. The paper layer is mainly used to stabilize the container and is usually thicker than the additional layer.

The container opening at the top of the container is surrounded by the opening edge. According to a simplified embodiment, this opening edge may be formed by the top of the two-dimensional cut. This edge becomes a simple cut edge without further treatment if there is no contact with the liquid in this area or if only slight contact is expected.

The opening edges or edges may be molded without folding, curling or changing the properties of the vessel wall. By treatment of this opening edge, additional rigidity of the container in the container opening area is obtained. In addition, the opening edges are treated by simply fixing with a lid or by covering the opening with a foil or other covering.

Treatment of the opening edge edge can be carried out after filling of the corresponding food.

In order to connect the thick metal layer and the paper layer to each other in a simple and stable manner, an adhesive corresponding to the connection is used, in particular in the layers of the overlapping portions. This overlap simplifies the manufacture of the corresponding cuts of both layers and the containers connected to each other.

Depending on the shape of the container and the capacity of the filled food, for example, it is provided only in a specific region of each of the paper layer, the metal layer, or the resin layer, and is connected with the paper layer. In order to simplify the products of cuts made of both layers, they are covered with each other, so that they generally coincide in shape, which means they have the same volume.

In the window area, it becomes more useful if an additional layer surrounds the window or covers each free edge of the paper layer laid around the inner or outer surface of the paper layer of the window area.

In general, the folding edges extending in the longitudinal direction of the container provide additional rigidity of the container. However, according to the invention, these folding edges may not be used, and the container is essentially rotationally symmetrical. This means that the intersection of the containers will be round or oval. According to the invention the corresponding rigid or folded corners are no longer needed.

In order to provide sufficient density and further stability of the window, according to the invention, the window foil is sufficient when the shape is similar to the window. This means that the window foil has essentially the same shape as the window, but can occupy a larger volume because it is heat bonded along the window edge between the window foil and the paper layer. This thermal bonding is usually carried out by applying heat and pressure because a deep connection between the window foil and the paper layer is obtained.

With respect to the window foil, at the inner surface of the paper foil, at the inner surface of the resin layer as an additional layer, at the outer surface of the metal layer as an additional layer meaning the outer side of the container, and the window edge between the paper layer and the additional layer. Are arranged by thermal bonding along, and are thermally bonded there.

Only one window foil may be arranged by bonding to a plurality of windows. Each thermal bond is carried out individually along the area surrounding all windows or for the edge of each window.

In essence, the window foil may be heat bonded throughout the inner surface of the paper layer. This simplifies the product without having to assign a smaller portion of the window foil to individual windows of the cup. Production with essentially three layers of cuts with these metal layers, paper layers and window foils is carried out in a kind of laminate, in particular in a single process step.

For the window foil, the other members may be particularly transparent or at least translucent even after connection to the paper layer. This member is also suitable for thermal bonding. Examples of such members are polyethylene, polypropylene, polyvinylchloride, polystyrene, polyamide, PET and the like.

In a simple way, in particular in order to produce the container wall in one cut, the connection of the cup with itself must be effected by heat and / or pressure and / or by using an adhesive. The connection of the cup with itself can be done in other ways.

According to one embodiment, the cuts are connected with themselves along the side edges of the cuts which are arranged to engage each other.

By this arrangement, the outer surface of the container has no overlap, and the thickness of the container wall is relatively gentle, since it is particularly constant along the outer circumference of the container wall. A simple example of such a connection with a cut of itself is, for example, when the cut connects with itself along an overlapping region extending in the longitudinal direction of the container. This overlap region generally does not include window foils, but only layers made of paper and metal, which are arranged overlapping each other and connected to each other. Corresponding connection of the cups is effected by an adhesive as described above and may additionally apply heat and / or pressure.

Corresponding edges of the cut can be liquid sealed to most effectively make such a container and in particular a container wall for the movement of food. Such liquid tightness occurs, for example, at the edges surrounding the window, at the edges forming the opening edges, and at the edges aligned inside the container. Such a fluid density can be obtained by covering the corresponding sealing material or by using an additional film or foil of the resin member. This resin foil covers the paper layer, in particular outside of the window foil, in particular by a liquid tight method. The foil of this resin member may be arranged between the paper layer and the window foil. In this case, thermal bonding is performed between the window foil and the resin layer.

To improve the visible appearance of the container, the metal layer has a print on its outer surface. Such printing may be used for displaying content or for reasons such as advertising elements. Also, the printed matters may have a three-dimensional effect so that the visual effect may be further improved. The printed matter which has such a three-dimensional effect is a hologram, for example.

Prints may be arranged anywhere on the outer surface of the container, and may be on a window or on each window foil. Simple examples of such prints printed directly on a window include, for example, marking of the filling height in the form of capacity units. There is no inherent limitation on the shape or printing color of the picture, in particular metal foil, which has good usability for printing.

In the window area it is more useful to have the first visible print after at least partial food has been taken out. For example, if the printout of the window is the color of the food in the container, it will only be visible after the food is removed. This can be used for some surprise effects or some sort of drawing.

Other shapes of containers are also possible. The first form is, for example, a cone form used for waffles and the like for containing ice cream as food. Instead of waffles, ice cream cladding made of chocolate, or other harder and more edible material than ice cream may be used. You can fill it in a container or fill it with ice cream. Here, the container is used essentially only as a cover for the waffle or chocolate sheath.

 The shape of the other container is a so-called squeezable container, which is also essentially conical. At its lower end, this pressurized container generally has a flag-like continuity formed by pressing the lower ends of the vessels together and connecting the vessel walls with themselves. From this flag-shaped end, the contents of the container can be taken out through the upper container opening by this manual pressing of the container wall.

In addition, the container may be essentially cup-shaped and may be used for cold beverages. In such cup-shaped containers, the closed lower end consists of a bottom insert and the container opening capable of closing the lid is in particular at least partly formed of a transparent member. The use of such a bottom insert and its connection with the bottom wall is generally known.

If this bottom insert and / or lid is also made of a transparent member, it can be used in addition to a window for viewing the inside of the container.

It is believed that the unique container shape is advantageous when such a container can be loaded and loaded.

The corresponding window is used for inspection of the container essentially along the total height of the container, and the corresponding window essentially extends in the longitudinal direction of the container. Therefore, a decrease in the filling height can be seen, in particular, as the food is taken out of the container. It is also possible to see if the container is actually filled with the food indicated.

The windows or windows have different shapes and can be arranged in different ways. Examples of such window shapes are angled shapes, in particular rectangular, oval, circular, essentially rhombus or other shapes. Each of these windows is arranged side by side and / or above each other in the circumferential and / or longitudinal direction of the container. Different shaped windows may be combined in one container. Another arrangement of the windows may in particular form a circular pattern of decreasing diameter, for example in a shape pattern, for example in the longitudinal direction of the container towards the top or bottom, and the arrangement of the windows may also be a kind of face, or a picture known to children. Can be achieved.

The shape of the other window extends essentially spirally along the longitudinal axis of the container. Also here, a plurality of windows can be arranged in the container.

According to one embodiment of the invention, food can be taken out of the container through the container opening. It is necessary to first remove the lid arranged in this area.

The lid can be removed by means of the corresponding lid handle without damaging the vessel wall. The upper region of the vessel wall in the cutout region of the vessel wall may be removed together with the lid. These perforations are formed in a variety of ways. One example is thinning of the member.

To simplify the cutout of this cutout area, a handle may be assigned to the cutout. The tear line may extend essentially along the upper and / or lower lids of the container. This allows the cutting line to be formed by the edge of the window foil. This is also valid if a plurality of windows overlap each other in a spiral or otherwise.

This arrangement of the perforations in the window area is more beneficial when the handles of the perforations are arranged in the window foil or eventually formed by the window foil. Therefore, each area of the container wall is along a perforation line or a plurality of perforations, so that the interior of the container is removed by the cutting handle and the window foil connected thereto, and is easily accessible for taking out the food.

The present invention also includes a two-dimensional cut corresponding to producing a container as described above.

With respect to this cut, the window can be manufactured in essentially two different ways and can be fluidly closed by the window foil.

According to the first embodiment, the cut is formed only of a paper and a metal layer. In the cut before application to the window foil, the windows or plural windows are arranged by cutting or stamping. The corresponding cut need not be a single cut, but may have a cut web arranged in succession with each other such that a plurality of cuts correspond. Only after producing the corresponding window is the window foil heat bonded to the inside of the paper layer by heat and / or pressure.

According to another embodiment, the window may be manufactured after feeding the window foil by cutting or pressing only to the paper and metal layers. In this case, cutting or pressing is performed from the cut side which will later become the outer surface of the container. Corresponding cuts are formed only on the container wall or cut of each of the metal and paper layers, but not on the window foil thermally bonded to the paper layer.

In the following, useful embodiments of the invention are shown in connection with the drawings.

11 is a perspective side view of another embodiment of a cut shaped container according to the present invention;

12 is a plan view of a two-dimensional cut for the container according to the invention shown in FIGS. 2 to 8.

1 is a perspective side view of a first embodiment of a container 1 according to the invention. It is essentially conical, and at its lower end 8 comprises a compressed flag 33 which is formed by pressing the container wall 5 in this region. The flag 33 is used as a handle of the container 1. Corresponding food filled in the interior of the container 1 can be pushed out by pressing the container 1 from the flag 33 in the direction of the container opening 7 of the upper end 6 of the container 1.

Similar to a belt, the container 1 consists of a window 10 which at least partially extends from the container wall 5 in the circumferential direction of the container 1.

The container opening 7 is surrounded by the radially curled opening edge 13 outward in the depicted example.

In figure 2 a second embodiment of a container 1 according to the invention is shown in perspective side view. This container is essentially different from the container according to FIG. 1 in terms of the absence of the flag 33 of the bottom 8. In the container 1, the food 2 similar to that in FIG. 1 reaches the filling height 28. Five windows 10 are arranged in the region of the food 2. They are circular and are formed in the longitudinal direction 23 of the container such that the radius decreases in the direction towards the bottom 8. Corresponding windows 10 are arranged to vertically overlap one another on the container wall 5.

As another embodiment, the additional window 10 is displaced in the circumferential direction 24 of the container wall 5 in view of the visible window and arranged in the container 1 according to FIG. 2. Examples of such an arrangement are displaced 90 or 180 degrees.

3 to 8, different embodiments of the container 1 according to the invention are shown differently in shape, arrangement and number of windows 10 than the container 1 according to FIG. 1. Each identical part has been referred to in part in connection with one figure, using the same reference numerals.

In this embodiment according to FIG. 3, two windows 10 of essentially rectangular shape are inclined and displaced parallel to one another in the vertical direction with respect to the longitudinal direction 23 of the container, as shown in FIG. 2. The window disposed close to the bottom 8 has a smaller length in the circumferential direction 24.

In FIG. 4, an essentially trapezoidal window 10 is arranged in the container wall 5. As shown in FIG. 2, the non-parallel sides extend parallel to the conical shape of the container, and the parallel sides of the trapezoid extend in the circumferential direction 24.

In this embodiment according to FIG. 4, the lid 22 is inserted into the container opening 7. The lid includes an edge rim extending upward along the edge and adhered to the inner surface of the container wall 5.

In FIG. 5, the window 10 has an elliptical shape extending in the longitudinal direction of the container. Adjacent to the side of the window 10, as shown in FIG. 9 of the container 1, a scale 34 is printed on another outer surface 20 of the outer layer 4. Corresponding printing may be applied directly to window 10.

According to the embodiment of FIG. 5, a lid 22 similar to FIG. 4 is provided. This is different from the lid described above in that the edge rim is arranged and maintained between the inner fold opening edge 13 and the inner surface 14, as shown in FIG. 9.

In FIG. 6, the window has a spiral shape extending along the longitudinal direction 23 of the container.

In this embodiment according to FIG. 7, the window extends essentially in the circumferential direction 24 and overlaps, as well as from the top and bottom 6, 8, as shown in FIGS. 1 and 2 of the container 1. Displaced from the area 17. The overlap region 17 is formed in part by the side edges which overlap one another of the two-dimensional cut for this container 1 as shown in FIG. 12. In this overlap area | region 17, a cut is connected with itself. For this connection, an additional adhesive can be applied. The connection can be effected by applying heat and / or pressure to the overlap region.

To replace this connection by overlapping, as shown in FIG. 12, the contact seams of these side edges and the corresponding side edges 15 and 16 of the two-dimensional cut 9 can be connected.

According to the embodiment of FIG. 7, the container wall 5 comprises a cutting handle 27 which touches the outer surface. Between this and the visible edge 15 of the two-dimensional cut of the outer surface of the container notch 35 is provided to maintain the cutting of the container wall for opening the container 1. This cut is supported by each cut line 25, 26, and the cut is essentially performed along the cut line 25, 26.

In FIG. 7, the upper tear line 26 extends parallel to the opening edge 13 between the opening edge 13 and the upper edge of the window 10. The second cutout line 25 is formed from the corresponding notch 35 inclined toward the bottom, so that the lower edge of the window foil 10 is sealed in this area, as shown in FIG. 9, to determine the cutout line 25. It extends to the lower edge of the window 10 used.

The other cut lines 25, 26 may be formed by partial cutting of the thinned member in the vessel wall 5 or a corresponding layer of the vessel wall.

In FIG. 8, the container 1 has a flat lid 22 with a lid handle 29 extending obliquely upward. This lid 22 is fed to the empty edge of the opening edge 13 and fixed there.

The windows 10 depicted in FIG. 8 have different shapes. The arrangement of these windows is face to face.

In FIG. 9, the figure cut | disconnected along the line VIII-V of FIG.

The cut is in particular through the window 10. The vessel wall 5 is in particular formed in two layers. The inner layer 3 is a paper layer and the outer layer 4 is a metal layer, for example an aluminum layer. The layers 3 and 4 cover each other in the cut 9, according to FIG. 12, and therefore generally coincide in shape with each other. The layers are connected to one another, in particular overlapping, by the application of an adhesive and heat and / or pressure.

The metal layer 4 may have a print on its outer surface 20. This printed matter can be used for advertising or the design of the contents of the container 1. Also, the printed matter may have a three-dimensional effect such as hologram, monochromatic or multicolor.

Corresponding printing may be applied to the window 10 such that the printed matter is visible only, for example, up to the amount that the corresponding food is arranged under the window 10 from the container 1. For example, this may be realized by a method of making the color of the printed matter 10 and the color of the filled food the same.

Transparent or translucent window foils 11 are arranged in the paper layer 3 along the inner surface 14 of the container 1 or along the edge area of the window 10. Along the corresponding edges, this foil is sealed to the inner surface of the paper layer 3 in the heat bond region 32. The corresponding window 10 is surrounded by the cutting edges 30, 31 of the metal layer 4 and the paper layer 3.

The metal layer 4 may extend around the corresponding cut edge of the paper layer 3, essentially on the inner surface 14.

In FIG. 10, the figure cut | disconnected along the line VIII-V of FIG. 1 of FIG. In the region of the container opening 7, the opening edge 30 curls radially outwards, in which the corresponding container wall 5 is made of a paper layer 3 and a metal layer 4. By plucking the opening edge 30, the corresponding characteristic of the vessel wall 5, such as liquid tightness, does not change.

In FIG. 11, an essentially cup-shaped container 1 is shown in another embodiment. It essentially extends over the total height of the container 1 and has an inclined window.

The container 1 is closed at its lower end 8 by the bottom insert 21 at the position opposite the container opening 7. This bottom insert generally includes a corner rim 37 extending vertically upwards from the bottom surface 36. This edge rim 37 fits between the wall edge of the container wall 5 folded upward and the inner surface 14 of the container wall 5 and is kept sealed therebetween.

In FIG. 12, a plan view of an embodiment of a two-dimensional cut 9 for a container in the shape of the embodiment of FIGS. 2 to 8 is shown. The two-dimensional cut corresponding to the embodiment according to FIG. 1 or 11 is evident.

The two-dimensional cut according to FIG. 9 consists of upper and lower edges 19 and 18 as well as left and right edges 15 and 16. With respect to the left and right edges 15, 16, it is used for the joining or overlapping region 17, as shown in FIG. 7.

The upper edge 18 of the cut 9 forms a corresponding opening edge 13, as shown in the preceding figures. This opening edge may be rolled, folded, or otherwise shaped as shown in FIG. 10.

According to the cut 9, the three windows 10 are arranged essentially parallel to each other. These windows are sealed by corresponding window foils 11 which are thermally bonded with the inner surface 14 of the paper layer 3 along the edge 12 of the window.

According to the depicted embodiments, a window foil 11 for the window 10 and an additional window foil 11 for the second window 10 are used. Corresponding window foils 11 may be used individually for each window 10, or as shown in other embodiments, only one window foil 11 may be used for all windows 10. Thermal bonding is effected in the region of the corresponding window 10 and at least in the corresponding thermal bonding area along the window edge 12.

The window foil 11 extends along the entire inner surface 14 of the paper layer 3 and may be thermally bonded to the paper layer 3 outside the window 10.

By arrangement of the window foil for one window according to FIG. 12, the window foil 11 and the window 10 become similar in shape. This means that the window foil and the shape of the window are the same, but the area of the window foil 11 is large since it extends over the window 10 and is heat bonded along its window edge 12.

In FIG. 12, as shown in FIG. 7, the cutting handle 27 with the corresponding notch 35 is additionally shown.

As shown in FIGS. 1 to 8, 11 and 12, for all embodiments according to the invention, the window 10 is arranged in an area in which the container wall 5 of the container 1 is curved. The stability and rigidity of the container 1 depends on this curvature of the container wall which is sufficiently high, even in the case of thin layers, in particular thin paper layers 3 and thin metal layers 4. Such containers are used, for example, in containers for filling, transporting and storing food. Stability and rigidity are improved by thermal bonding of the window foil 11. They extend similarly to the corresponding window 10 in the curved area of the container wall 5. In addition, the corresponding edges of the window foil 11 are used as cut lines 25 and 26, as shown in FIG. 7. Thus, the perforations 25, 26 arranged separately on the container wall 5 are not necessary.

The depicted embodiments of the container 1 are all rotationally symmetric in nature. However, as shown in particular in the container 1 according to FIG. 1, it may also have an elliptical intersection which is easily compressible.

With regard to the cut 9 according to FIG. 12 and similar cuts for another embodiment in the form of a container, essentially two further manufacturing methods are mentioned.

According to the first production example, the container wall 5 consisting of the paper layer 3 and the metal layer 3 is a laminate. In this laminate, the corresponding window 10 or a plurality of windows is formed by cutting or pressing. Thereafter, the window or plural windows are densely closed along the edge thereof with the window foil 11 arranged by heat bonding.

According to the second production example, each cut 9 is used in the formation of the container wall of the paper layer 3, the metal layer 4, and the window foil 11. And, the corresponding window 10 is formed by cutting or pressing using the Kiss-cut method, and in this way, the window is made of only a paper layer and a metal layer, and the window foil is not touched.

The window foil may in particular be a different transparent or translucent thermoplastic resin. One example is polyethylene.

In another embodiment, the bottom insert 21 or the lid 22 may be formed at least partially as a transparent or translucent member. As such, the contents of the container 1 can be observed through the bottom from the container opening 7 or from the bottom of the container.

According to another embodiment of the present invention, for example, as shown in FIG. 12, the cutting handle 27 is not formed of the paper layer 3 and the metal layer 4, but can be realized as an extension of the window foil 11. Can be. In this method, the cutting of the container wall along the cut lines 25 and 26 determined by the edge of the window foil 11 is simplified.

This cutting handle 27 is guided through the side edges 15 and 16 of the cut 9, which are connected to one another, for example, to the outer surface of the container 1.
