Definitions
- the present invention relates to a container, comprising a container wall partially surrounding the container wall, wherein the container wall
- a) has a container opening
- c) includes a first polymer layer at least partially overlapping the container layer
- a. in a plane perpendicular to a height of the container interior has a maximum diameter
- the invention relates to methods for overlying a container precursor with a polymer composition; a container obtainable by this method; an apparatus for overlying a container precursor with a polymer composition; a method for filling and closing one of the aforementioned containers and the closed container obtainable thereby; and uses of a filling machine, one of the aforementioned containers, a polymer composition, and a powder coating equipment.
- various containers are known for filling, transporting and storing of flowable food, be it food for human consumption or animal food products.
- Typical requirements for these containers are a low weight for transport; the largest possible variety of shapes in container production; the suitability for the most space-saving storage possible; mechanical stability, especially when stacking and emptying the containers; the tightness; the openability; and the pouring behavior.
- Another requirement that is becoming increasingly important is environmental compatibility. This in turn is a generic term for numerous aspects such as raw material and energy consumption in container production, the use of the largest possible share of renewable raw materials, the ability to Recy- celn and health compatibility.
- Exemplary flowable foods are drinks. In the following, briefly typical, known in the art beverage containers are discussed.
- Glass bottles have due to their substantially cylindrical shape the disadvantage that a very dense and space-saving storage is hardly possible. Glass bottles are limited to this form by their manufacturing process. Although other forms are available from glass, but these require some extra effort in the production and often lead to otherwise disadvantageous, for example, less stable, glass bottles. Due to their fragility, glass bottles generally have a considerable disadvantage, which also entails a risk of injury. As a result, glass bottles are banned at many major public events. In addition, glass bottles have a considerable weight, which leads to increased energy consumption during transport. Moreover, quite a lot of energy is needed to produce glass, even if the glass used for this purpose comes from recycling. In addition, aggravating an increased transport costs.
- the containers are typically made by folding the laminate and sealing certain laminate areas. Due to this type of production, the variety of shapes of these containers is limited. Thus, the laminates can not fold arbitrarily without loss of their tightness. In addition, round containers such as bottles of these laminates are usually difficult to produce, for example by the use of additional container components such as a separate container bottom made of plastic. Furthermore, these containers opening aids or additional tools are required to open.
- the laminates used are usually foldable but have a certain flexibility, the laminate containers are essentially dimensionally stable, but not as stiff and rigid as, for example, glass bottles. This leads to disadvantages in the stackability and also during pouring. As already stated, the laminates usually consist of a series of interconnected layers comprising different polymers and often also aluminum. Such multi-layer structures require some effort to recycle. The desire to improve the laminate containers has led in the prior art to increasingly complex layer composites with numerous different materials and material mixtures. The large number of polymers used is considered to be disadvantageous for environmental reasons, for example.
- the container according to the invention open up a novel container category.
- the inventors have devised an environmentally-friendly starting material which has hitherto not been considered for producing containers, particularly bottles, for flowable foodstuffs. So this material obtained from wood pulp is known only for egg cartons, so not for flowable food. That this environmentally friendly material made Renewable raw materials for egg cartons has been known for a long time and has not yet been considered for development for the use of the invention, shows that here, overcoming established technical prejudices, a completely new development strand has been opened.

- an object of the invention to provide a possible environmentally friendly Fla- see for flowable food that is as hygienic as possible, especially when drinking directly from the bottle. Furthermore, it is an object of the invention to provide a most environmentally friendly bottle for flowable food, which is suitable to be provided on its outside with a high-quality printed decor. Another object of the invention is to provide a bottle for flowable food that can be made in as wide a variety of different forms as possible. In addition, it is an object of the invention to provide a bottle for flowable food that is as simple as possible.

An object of the invention is to make this waterproof as large as possible and in this case preferably to keep the weight of the bottle as low as possible. In particular, the bottle is preferably as environmentally friendly as possible, preferably by using as few chemical additives as possible in bottle production.
