  1. USE OF A THERMOPLASTIC CASTING MATERIAL FOR THE MANUFACTURE OF CONTAINERS AND PACKAGING MEANS AND METHOD FOR THE MANUFACTURE OF A CONTAINER
    The invention relates to the use of a thermoplastic casting material for the production of containers, and to a method for producing such containers.
    Thermoplastic casting materials have been known for a long time and the production of items such as containers from such casting materials is also known in the prior art.
    For example, a permanently plastic modelling compound is known from DE 20 2006 001 786 U1. WO 2012/035102 A1 describes a stearin-based casting compound for the production of casts.
    Casting methods for the production of castings are described, among others, in WO 01/62833 A1 or in US 2013/225020 A1. The use of a thermoplastic casting material containing wax and filling materials for the production of containers and packaging means is known from
    KR 2009 0008117 A.
    The object of the present invention is to produce environmentally friendly bottles and cans as well as other items, such as packaging lines and containers for liquid organic cosmetic products, in a simple and inexpensive manner.
    Glass bottles have the disadvantage of breakage and plastics, as well as bioplastics, are not desirable for some applications, for example for aesthetic reasons or for ecological reasons.
    The object of the invention was to produce such containers at least for the most part from natural and non-toxic raw materials.
    Such containers should also be easy to manufacture and offer the necessary strength as well as safe disposal options.
    The invention is defined in the appended claims.
    The thermoplastic casting material is characterised in that the casting material contains a binder which is flowable under heat and solid at ambient temperature and at least one additive which does not melt at the melting temperature of the binder.
    According to the invention, the binder consists of one or more substances from the group consisting of vegetable wax, animal wax, paraffin wax, montan wax and stearin.
    When using waxes, it has been found that they do not have the necessary solidity.
    According to the invention, it has been surprisingly shown that the solidity can be significantly increased by adding an additive.
    According to the invention, this additive contains fibrous and filling materials.
    The additive may further contain one or more substances from the group comprising dyes, brighteners, viscosity-influencing substances, decorating substances and/or fragrances. The brighteners are preferably made of natural resin and shellac. These substances also serve as surface sealants and binders. Natural resins may be selected from the group comprising dammar, ester gum, glycerol ester of root rosin (E 445), gum benzoin, gum elemi, gum mastic, gum sandarac, rosin, copal manila, for example. Advantageously, the fibrous materials are selected from the following group: - Natural fibres, plant fibres, wool, hair, silk, mineral fibres of geological origin - Man-made fibres from natural polymers such as viscose, modal, lyocell, cupro, acetate, triacetate, gum, plant protein, animal protein, starch, glucose, alginate, chitosan - Man-made fibres from synthetic polymers such as polyester, polyamide, aramid - Man-made fibres from industrially produced inorganic fibres such as glass, carbon, ceramics, metal - Textile fibres - Paper fibres - Recycled fibres. The fibrous materials may vary in length. Preferably, the length of the fibres is less than 10 mm, more preferably less than 2 mm, in particular it is between 0.01 and 1 mm. Preferably, the filling materials are selected from the following group: powdered materials, individually as well as in a mixture, such as annaline, basalt, pumice, dolomite, glass, garnet, granite, wood ash, kaolin powder, bone ash, marble, meerschaum, whey protein, quartz, chamotte, precipitated chalk, silk protein, silicon oxide, talc, volcanic ash, bentonite, cristobalite, mica, diatomaceous earth, montmorillonite, Neuburg Siliceous Earth, wollastonites, zeolite. According to further features, the casting material contains up to 30 wt.-% fibrous material. Furthermore, the casting material may contain up to 90 wt.-% filling material. Preferably, the casting material may contain up to 75 wt.-% filling material and up to 25 wt.-% fibrous material, however, together never more than 95 wt.-% based on the total weight of the casting material. Particularly preferred is the wax carnauba wax. The casting material is used for the production of containers. Such containers may be filled with liquids or powdery or free-flowing substances, such as detergents, perfumes,
    etc., which may also be sealed with the casting material. The sealing may be done under exclusion of air by pouring the casting material in a liquid or viscous layer over the opening of the filled container or by placing it over the container.
    While displacing the air, the seal solidifies until it is opened again.
    The manufacturing processes for items such as containers may be taken from the known technology.
    For example, the casting material may be poured in liquid form into a corresponding mould and, after a certain cooling time, any remaining liquid material may be poured out to form a container.
    When the temperature falls below the melting point,
    cooling reaches a solidification point at which the mould can be opened and the item removed.
    In addition to this slush moulding method, other methods may be used, such as, injection moulding, transfer moulding, extrusion, deep drawing, calendering, rotational moulding, bladder moulding as well as internal pressure injection moulding.
    When wax mixtures according to the invention are heated to e.g. 90 to 100°C, the casting material is liquid.
    When cooling down to e.g. 50 to 60°C, the material is rigid enough to initiate the demoulding process.
    The hardness of the manufactured item and its solidity may be determined by the choice of additives and their proportion by weight in the casting compound.
    The fibrous materials, particularly in combination with filling materials such as precipitated chalk or kaolin, result in containers with high breaking strength.
    A particular advantage of the containers or items made from the cast material is the pleasant feel, as the surface is slightly waxy and pleasant to the touch.
    Since natural waxes are biodegradable, the items can be easily disposed of as they are ecologically harmless.
    The following are non-limiting examples of the casting material:
    Example 1
    Production of a vessel using the slush moulding method Casting material: 31 wt.% carnauba wax
    65 wt.% calcium carbonate 4 wt.% cellulose fibers
    The casting material is heated until it is thin and then poured into the mould.
    After a sufficient time - depending on the thermal conductivity of the mould - the remaining liguid part of the casting material is poured out, the mould is opened and the formed vessel is removed.
    The proportions of ingredients may vary considerably, for example 25 - 35 wt.% carnauba wax, 60 - 70 wt.% calcium carbonate, 3 - 7 wt.% cellulose fibres.
    Example 2 Sealing of a vessel Casting material: 37 wt.% beeswax 60 wt.% calcium carbonate 3 wt.% cellulose fibers The casting material is heated to a viscous state and poured over the filling opening of the vessel after it has previously been filled with a filling material.
    Alternatively, a plastically soft plate may be formed from the casting compound, which is placed over the filling opening and pressed out.
    The proportions of ingredients may vary considerably, for example 35 - 40 wt.% beeswax, - 65 wt.% calcium carbonate, 2 - 5 wt.% cellulose fibres.
    The casting material may be used to produce packaging means, such as vessels, bottles and other containers, as well as their closures and lids.
