Definitions

  • the invention relates to a container for holding a food with at least one layer of paper and a further layer having a container wall, the container having a container opening at its upper end and being closed at its lower end opposite the container opening, at least the container wall being formed from a two-dimensional blank is, which is connected to form a continuous container wall, and wherein at least one viewing window is formed in the container wall, which is closed by a transparent or translucent window film.
  • Such a container is known in practice, for example, for essentially cuboidal liquid containers.
  • these In a flat side wall, these have a viewing window which extends in the longitudinal direction of the container and which serves to check the fill level of the liquid filled in the container.
  • the paper layer of the container is made of relatively stiff cardboard material and has a fluid-tight additional layer made of a plastic material on its inside.
  • the viewing window is essentially formed only in the relatively rigid paper layer and is closed on the inside of the container by the corresponding fluid-tight film, which is transparent or at least translucent.
  • essentially cuboid containers are known from practice, which are used, for example, to hold dry food such as rice, pasta, flour, sugar or the like.
  • a film is generally glued in from the inside of a viewing window in a flat side wall of the container.
  • the paper layer is relatively stiff and made of cardboard material, for example.
  • This paper layer together with the corresponding folds to form the top and bottom sides and the side surfaces arranged in the circumferential direction, gives the container a relatively high rigidity.
  • the window film only serves as a cover for the speaking viewing window so that a liquid or a dry food cannot leave the container through the viewing window.
  • the invention has for its object to improve a container of the type mentioned in such a way that even when using very thin paper layers and without further folds or fold lines of the corresponding cut to form a three-dimensional container, sufficient stability of the container is possible while maintaining a corresponding viewing window ,
  • the container is characterized in particular in that the container wall is at least partially curved in the region of the viewing window. This curved course results in increased rigidity and thus stability for the finished container.
  • the window film for sealing the viewing window is heat sealed with the paper layer. Such a heat seal results in intimate contact between the window film and the paper layer, which in addition to the curvature of the wall further stabilizes and stiffens the container wall and thus the container.
  • a viewing window is also possible for very thin-walled containers, although the corresponding rigidity and stability of the container is still sufficient, for example, to remove food from its container opening.
  • the viewing window in the curved area of the container wall and the heat sealing of the window film at least in this area also support the dimensional stability with regard to the shape of the container. Without the features according to the invention, such a container would otherwise not be sufficiently dimensionally stable without filling in order to be able to simply fill or store it, for example.
  • the corresponding curvature of the container wall in the region of the viewing window results in sufficient stability in the circumferential direction as well as in the longitudinal direction of the container.
  • the window film is heat-sealed to the paper layer at least in the area of a viewing window edge. This heat sealing then takes place at least along the entire edge of the viewing window in order to adequately seal the viewing window.
  • another type of fastening between window film and paper layer can also take place outside the window edge or further away from the window.
  • the further layer can be a metal layer, in particular an aluminum layer.
  • a metal layer is advantageously applied to a corresponding outside of the paper layer.
  • a plastic layer can be applied as a further layer to a corresponding inside of the paper layer.
  • This plastic layer is for example made of polyethylene or another plastic such as, polypropylene, polyvinyl chloride, polystyrene or the like.
  • the corresponding further layer is used in particular for barrier properties, that is to say it serves for the appropriate tightness with regard to gas and liquids.
  • a metal layer is particularly helpful for edge formation when the opening edge is curled, bent or otherwise deformed.
  • the metal layer can also make it easier to tear open the container.
  • the paper layer mainly serves to stabilize the container and is usually thicker than the other layer.
  • the container opening at the upper end of the container is surrounded by an opening edge.
  • this can be formed by an upper edge of the two-dimensional blank.
  • the edge can be a simple cut edge without separate treatment if, for example, little or no contact with liquid is to be expected in this area.
  • the opening edge is folded, rolled or folded, in particular without changing the properties of the container wall. Processing the opening edge in this way results in additional stiffening of the container in the region of the container opening.
  • such a machined opening edge can be more easily used to attach a lid, film, or other opening cover.
  • This processing of the opening edge can also only take place after the appropriate food has been filled in.
  • the metal layer or the plastic layer is only applied to a certain area of the paper layer and is connected to the paper layer.
  • these can be essentially congruent, that is to say they have the same dimensions, so that they are congruent with one another.
  • the further layer covers corresponding free edges of the paper layer that surround the viewing window, or is even laid around the inside or outside of the paper layer in the area of the viewing window.
  • folding edges that extend in the longitudinal direction of the container stiffen the container. According to the invention, it is possible that there are no such folded edges and the container is essentially rotationally symmetrical. That is, in cross section the container can be circular or oval. Corresponding stiffening or folding edges are not necessary according to the invention.
  • the window film is geometrically similar to the viewing window. This means that the window film has essentially the same geometric shape as the viewing window, but takes place over larger dimensions, so that a heat seal can take place along the window edge between the window film and paper layer. This heat sealing is usually carried out under the influence of heat and pressure, so that the intimate connection between the window film and the paper layer is established.
  • window film With respect to the window film should also be noted that these by heat sealing on the inside of the paper sheet on the inner side of the plastic layer as an additional layer on the outside of the metal layer as an additional layer, that is on the outside of the container, and also for example along the window border between Paper layer and another layer arranged and there can be heat sealed.
  • the window film prefferably be heat-sealed essentially on the entire inside of the paper layer. This simplifies production overall, since no smaller window film sections have to be assigned to each of the viewing windows of a blank.
  • the production of such a blank from essentially three layers, that is to say the metal layer, paper layer and window film, can likewise take place in the manner of a laminate and in particular in one operation.
  • the window film which are transparent or at least translucent in particular even after being connected to the paper layer. These materials should also be suitable for heat sealing. Examples should rather materials are polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamide, polyethylene or the like.
  • the blank can be connected to itself by heat and / or pressure and / or by using an adhesive.
  • connection of the blank to itself can be done in different ways.
  • the blank is connected to itself along side edges of the blank that are arranged in abutment.
  • the outer surface of the container is relatively smooth since there is no overlap and the thickness of the container wall is constant, in particular along the circumference of the container.
  • a simpler embodiment for connecting the blank to itself can be seen if it is connected to it along an overlap region which extends in particular in the longitudinal direction of the container. As a rule, this overlap area does not cover the window film, but only the layers of paper and metal arranged one above the other and connected to one another.
  • the corresponding connection of the blank takes place, see also the above explanations, by means of an adhesive and, if appropriate, additionally by supplying heat and / or pressure.
  • edges of the blank can be fluid-tight.
  • This fluid tightness relates, for example, to the edges surrounding the viewing window, the edge forming the opening edge and also an edge which may be arranged in the interior of the container.
  • Such fluid tightness can also be achieved by applying an appropriate sealant by using a further film made of a plastic material.
  • a plastic film can in particular cover the paper layer in a fluid-tight manner outside the window film.
  • this plastic film between the paper layer and the window is arranged. In this case, the heat seal between the window film and the plastic layer can be carried out.
  • the metal layer can have an imprint on its outside. Such an imprint can serve both to identify the content and for advertising purposes or the like.
  • Imprints with a three-dimensional effect are also possible, as a result of which the optical appearance can be further improved.
  • Such an imprint with a 1-dimensional effect is for example a hologram.
  • the imprint can be arranged anywhere on the outside of the container, it also being possible to imprint on the viewing window or on the corresponding window film.
  • a simple example of such a print directly on the viewing window is, for example, a fill level marking from a scale or the like.
  • the viewing window it can also prove to be advantageous if it has an imprint that is only visible after the food has been at least partially removed. If, for example, such a window print has the same color as the food arranged in the container, the print is only visible when the food has been removed. This can be used for a surprise effect and also for competitions or the like.
  • the container essentially serves only as a cover for a waffle or chocolate cover.
  • Another container shape is a so-called squeeze container, which is also essentially conical. At its lower end, such a squeeze container generally has a flag-shaped continuation, which is formed by compressing the lower end of the container and connecting the container wall to itself. From this flag-shaped end, the contents can be removed from the container by further manually squeezing the container wall through the upper container opening.
  • the container can also be essentially cup-shaped and used for cold or warm drinks.
  • the closed end of the container can have a bottom insert, which, if appropriate, and a lid closing the container opening, in particular, are formed from an at least partially transparent material.
  • a floor insert and its connection to the container wall is known per se.
  • this bottom insert and / or the lid are also made of transparent material, they can be used in addition to the viewing window to look inside the container.
  • a viewing window can extend essentially in the longitudinal direction of the container. This shows in particular how the fill level in the container gradually decreases as a result of the food being consumed. It can also be seen whether a specified amount of food is actually filled in the container.
  • the viewing window or windows can have different geometric shapes and can be arranged in different ways. Examples of viewing window shapes are square, in particular square, oval, round, essentially rhombic or other shapes. Several of such viewing windows can be arranged side by side and / or one above the other in the container circumferential and / or container longitudinal direction. There is also the possibility that different geometrically shaped viewing windows can be combined with each other in one container.
  • Arrangements of viewing windows which result in a specific geometric pattern are also possible, such as circular viewing windows with a diameter decreasing up or down in the longitudinal direction of the container, an arrangement of viewing windows which correspond to an abstract face or the like or which represent familiar figures or the like in children.
  • viewing windows runs essentially in a spiral around the longitudinal direction of the container.
  • several viewing windows can be arranged in one container at the same time.
  • the food can be removed from the container via the container opening.
  • a cover arranged in this area may have to be removed.
  • the lid can be removed using an appropriate lid handle without damaging the container wall.
  • a tear line being formed in the container wall in this region, for example.
  • Such a tear line can be designed in different ways. An example is material weakening.
  • the tear line can be assigned a tear handle.
  • the tear line can essentially also run along an upper and / or lower edge of the viewing window. It can pass through an edge of the window film be educated. This also applies analogously to a plurality of viewing windows arranged one above the other, spiraling or arranged in another way.
  • the tear line is arranged in the region of the viewing window, it can furthermore prove to be advantageous if the tear handle is arranged on the window film or, if appropriate, formed by it. As a result, the corresponding area of the container wall along the tear line or lines is removed by means of the tear-open handle and the window film connected to it, and the interior of the container is sufficiently accessible for food removal.
  • the invention also relates to a corresponding two-dimensional blank for producing a container described above.
  • viewing windows can be produced essentially in two different ways and can be sealed tightly by the window film.
  • the blank is first made up of only paper layer and metal layer.
  • the viewing window (s) are arranged by cutting or punching out before the window film is attached.
  • the corresponding blank does not have to be a single blank, but can be a blank in which several blanks are arranged relative to one another. Only after the corresponding viewing window has been produced is the window film then heat-sealed to the inside of the paper layer by means of heat and / or pressure.
  • the viewing window can also be produced after the window film has been applied by cutting or punching out only the paper and metal layer.
  • the cutting out or punching out takes place from the side of the blank which later forms the outside of the container, a corresponding cut into the container wall or into the blank being made only by means of the metal layer and paper layer, but not as far as the window film heat-sealed on the paper layer.
