Description

Subject of the invention

The Invention, with reference to the preamble of the patent claim 1, a planter in any Shaping made of a composite material and / or granules preferably in the thermoplastic injection molding process.

The Planter according to the invention, also in general parlance plant or flower pot called, consists at least one thermoplastic polymer and at least one vegetable matter, preferably wood flour and / or wood grain and / or Wood fiber and at least five Weight percent talcum and contains additionally at least one porous, open-pore thermoplastic polymer and / or a porous, open-pore thermosetting polymer. The total content of thermoplastic polymers in the planter invention is not allowed greater than fifty Percent by weight and the proportion of botanicals should be at least thirty Weight percent lie.

Such Planters are ideally suited for planting with plants of all kinds and are also suitable for the cultivation and / or germination of seeds and as waterproof and unbreakable decoration pots for flowers and flowers Planters that made of clay and other fragile and non-waterproof materials consist.

State of the art

Known are planters, plant pots and Decorative pots that preferably in thermoplastic injection molding of pure Plastic or wood-plastic material mixtures are made. Preferably of polypropylene and copolymers of the polypropylene in Blend with wood flour and / or wood grain or wood shavings. These Wood-plastic mixtures are first processed to planters via twin screw extruder before processing molded to compact granules or compacted via heating-cooling mixer, so that this Mixtures on conventional Process injection molding machines. It is also known cellulose fibers to process in such mixtures and / or these with others to combine botanicals.

Of the Proportion of vegetable substances, such as wood flour, is usually under fifty Weight. The homogeneity and stability the planters made from such mixtures and / or granules is very inadequate.

This is partly due to an unstable bond of the thermoplastic Polymers to the introduced, vegetable substances. The material costs are very high as the proportion of inexpensive botanicals too is low to the extra To compensate for mixing and granulation costs. These planters also have still a plastic look due to the partly very high Proportion of plastic, which amounts to up to 70% in the total mixture can. The water absorption capacity the planters made from such mixtures is at over ten percent by weight and can, with reduction of the polymer content for example, thirty Percent by weight, up to twenty percent by weight. this has then in a use of planters from such mixtures As a result, they are destroyed by frost and also used as a planter indoors are not suitable because the irrigation water diffused out of the planter and this leads to spots, for example on window sills. In addition, that is at the use of slightly calciferous irrigation water and / or the use from liquid fertilizer the outer wall the planters themselves unsightly Make stains.

Problematic is also the color, as the vegetable admixtures, For example, the wood grain, very difficult and costly dye to let. It is practically impossible a visually beautiful Coloring towards pleasing Terracotta hues adjust. All this is one reason why planters are made of such Wood-plastic mixtures could not prevail so far in the market. This also applies to corresponding planters made of thermoplastic Polymer with other botanicals.

invention task

• – homogenes, leicht einzufärbendes Materialkomposit
• – hoher Anteil an pflanzlichen Stoffen und geringer Anteil an thermoplastischem Polymer
• – geringe Wasseraufnahme und dadurch gute Frostbeständigkeit
• – verbunden mit einer gewissen Atmungsaktivität
• – bruchsicher und leicht im Gewicht
• – homogene Einbindung von Farb-, Wirk- und Duftstoffen in die Pflanzgefäße

The invention has for its object to find planters and the material composites and / or granules required for their preparation in the thermoplastic injection molding process, the signs th disadvantages and bring additional benefits, such as:

• - homogeneous, easily colored Materialkomposit
• - High content of vegetable substances and low proportion of thermoplastic polymer
• - Low water absorption and thus good frost resistance
• - associated with a certain breathability
• - unbreakable and light in weight
• - homogeneous integration of colorants, active ingredients and fragrances in the planters

This associated with low overall costs in the production and in the Composition of planters and material composites and / or granules.

Solution of the problem of the invention

• – mindestens fünf Gewichtsprozent Talkum, vorzugsweise mit einem Anteil von zehn bis fünfzehn Gewichtsprozent,
• – mindestens ein poröses, offenporiges thermoplastisches Polymer und/oder ein poröses, offenporiges duroplastisches Polymer,
• – mindestens dreißig Gewichtsprozent pflanzliche Stoffe,
• – maximal fünfzig Gewichtsprozent thermoplastisches Polymer, vorzugsweise dreißig Gewichtsprozent.

Surprisingly, it has been found that the object according to the invention is achieved in that the planters and the material composites and / or granules required for their production must be composed as follows, so that they can be produced inexpensively using conventional production techniques. Since these production techniques are comprehensible as state-of-the-art and for every specialist, details will be omitted as far as production technology and known material specifications are concerned. It must be included in the planters according to the invention, with reference to the right to claim 1, in principle:

• At least five percent by weight of talc, preferably in a proportion of ten to fifteen percent by weight,
• At least one porous, open-pore thermoplastic polymer and / or a porous, open-pore thermoset polymer,
• - at least thirty percent by weight of herbal substances,
• - Up to fifty percent by weight of thermoplastic polymer, preferably thirty percent by weight.

Planters made from material composites and / or granules of this composition meet surprisingly fully meet the requirements arising from the task of the invention result.

It was also found that further advantageous embodiments of the invention thereby possible are, that the added porous, open-pore thermoplastic polymers and / or the porous, open-pore Thermosets are loaded with active ingredients and / or fragrances, so that these are finely distributed homogeneously integrated in the planters. This is particularly advantageous when the products according to the invention, for example with repellents to repel plant pests and / or for example perfumes, in particular with essential oils, are to equip.

Thereby is it possible, for example, equip the planters of the invention with micronutrients, through the action of water over slowly released for a very long time and delivered to the potting soil become.

In addition was found that the total amount of botanicals significantly increase, if as herbal substance Coir Fiber Pith (CFP), this is an open-pored, spongy, vegetable material used in the extraction of Coconut fiber is produced as waste, whole or with a large one Proportion of the total amount of plant substances used, da Coir Fiber Pith (CFP) due to its high lignin content below Pressure and temperature has thermoplastic properties and thus the proportion of herbal substances up to eighty percent by weight elevated can be. The addition of Coir Fiber Pith (CFP) additionally improves the Breaking strength of the planters invention and reduced their water absorption capacity essential.

embodiments

example 1 54.00 kg dried wood flour with a grain size of 300-500 microns 30.00 kg Finely shredded polypropylene copolymer regenerate with a melting point of 220 ° C. 1.00 kg porous, open-pored polypropylene with a pore volume of 80% by volume and a melting point of 240 ° C 12.00 kg Talcum powder with a grain size of 20-30 microns 3.00 kg mineral terracotta pigment with a particle size <50 microns = 100.00 kg total mixture

These Material mixing was done in a fast-running heating-cooling mixer intimately mixed at a temperature of 180 ° C and then this composite material with a twin screw extruder converted to granules, the one bulk weight of 650 g per liter and a specific gravity of 1.22 g / ml. From this granules were then in the thermoplastic injection molding process Planters with a medium wall thickness of 4 mm, a part weight of 580 g and with a filling volume made of 6 liters.

These Draw planters characterized by a very homogeneous material structure. The optics and Color was similar of clay or terracotta planters. The planters are extremely shatterproof and frost resistant, also after previous storage over a period of 4 weeks under water. The absolute water absorption is 4.55 weight percent.

• – geringeres Gewicht
• – extrem bruchfest
• – frostbeständig
• – absolut wasserdicht
• – atmungsaktiv

und preisgünstig in der Herstellung und leicht zu bearbeiten mit herkömmlichen Holzbearbeitungsmaschinen, denn dies erleichtert zum Beispiel das Bohren von zusätzlichen Wasserabfluss-Öffnungen am Boden der Pflanzgefäße. Beispiel 2 36,00 kg getrocknetes Holzmehl mit einer Korngröße von 300–500 Mikrometer 30,00 kg Polypropylen-Copolymer-Regenerat als Mahlgut aufbereitet, Schmelzpunkt 220°C 2,00 kg poröses, offenporiges Polypropylen mit einem Porenvolumen von 80 Volumenprozent und einem Schmelzpunkt von 240°C 7,00 kg Mahlgut eines porösen, offenporigen Polyurethanschaums mit einer Partikelgröße von 150–800 Mikrometer, Dichte 80 kg/cbm 20,00 kg Talkumpulver mit einer Korngröße von 20–50 Mikrometer 5,00 kg mineralisches Terrakotta-Pigment mit einer Korngröße <50 Mikrometer = 100,00 kg Gesamtmischung These planters are ideal for indoor and outdoor use for all plants and their material and performance properties are superior to conventional plastic planters and clay ones. The following advantages are for example to be emphasized in comparison to fired clay pots:

• - lower weight
• - extremely unbreakable
• - frost resistant
• - absolutely waterproof
• - breathable

and inexpensive to manufacture and easy to work with conventional woodworking machines, as this facilitates, for example, the drilling of additional water drainage holes at the bottom of the planters. Example 2 36.00 kg dried wood flour with a grain size of 300-500 microns 30.00 kg Polypropylene copolymer regenerate prepared as regrind, melting point 220 ° C. 2.00 kg porous, open-pored polypropylene with a pore volume of 80% by volume and a melting point of 240 ° C. 7.00 kg Ground material of a porous, open-pored polyurethane foam with a particle size of 150-800 microns, density 80 kg / cbm 20.00 kg Talcum powder with a grain size of 20-50 microns 5.00 kg mineral terracotta pigment with a particle size <50 microns = 100.00 kg total mixture

The Preparation and processing of this total mixture took place as in Example 1 described to planters identical dimension.

The inventive planters were in their properties comparable to the planters according to example 1, however, these had, what was desired, a slightly porous structure in the mass, which improved the breathability of the planters. These planters showed an increased Water absorption, which was 6.88 percent by weight. The coloring was uniformly homogeneous. The part weight of the planters was included 650 g.

These planters according to the invention are ideal for outdoor use and can replace the extremely fragile clay and terracotta pots, are lighter than this and thereby better in handling. Example 3 52.00 kg dried wood flour with a grain size of 300-500 microns 28.00 kg Finely shredded polypropylene copolymer regenerate with a melting point of 220 ° C. 5.00 kg porous, open-pored polypropylene with a pore volume of 80% by volume and a melting point of 240 ° C, pores loaded with 2.5 kg of pure lavandin oil 12.00 kg Talcum powder with a grain size of 20-30 microns 3.00 kg mineral terracotta pigment with a particle size <50 microns = 100.00 kg total mixture

The 5 kg porous, open-pore polypropylene with a pore volume of 80 percent by volume and a melting point of 240 ° C, loaded with 2.5 kg of pure lavandin oil, consist of 2.5 kg of polypropylene and 2.5 kg of lavandin oil, that is incorporated into the open pores of the polypropylene as agent depot is.

The Preparation and processing of this total mixture took place as in Example 1 described to planters identical dimension. The plant containers according to the invention produced in this way correspond in their material and performance characteristics of the planters according to example 1 with the difference that over a period of time the scent of lavandin oil give off and thus a pronounced repellent effect against ants infestation and at the same time Make sure that the lavender scent attracts plant pollinating bees acts.

Under Reference to the right to claim 1, in conjunction with claim 3, so it is possible the planters according to the invention with the equip different active ingredients. Instead of the porous, open-pored thermoplastic polymers can as a carrier for the Loading also corresponding thermoset polymers and / or combinations these polymers are used. This opens up the planters according to the invention new Applications and applications in commercial plant breeding, because the combination of repellent effect on the one hand and attractant on the other is very beneficial and currently not with conventional planters possible.

Example 4

In this embodiment the recipe of Example 1 was used and the wood flour completely through Coir Fiber Pith (CFP) with a particle size of 1000 to 3000 microns replaced and the proportion of shredded polypropylene copolymer reduced to twenty percent by weight and the difference by addition of another 8 kg of Coir Fiber Pith (CFP).

In order to increased the proportion of botanicals is 62% by weight. The terracotta pigment was colored by brown inorganic color pigment replaced on the basis of iron oxide. The preparation and processing This total mixture was carried out as described in Example 1 Planters identical Dimension.

The had thus prepared inventive planters almost identical material properties but is beneficial in this embodiment the invention that by saving considerable amounts of thermoplastic Polymer, these planters very much inexpensive are to produce.

Advantageous in this embodiment of the invention is also that the optics this planters to dark Tropical wood recalls and thereby these are very decorative and special suitable for use in living areas or as decorative planters with Wood-look. Also in the outdoor area These planters are due their high color and UV stability of advantage.

The Examples 1 to 4 illustrate by way of example the many possibilities and advantages of the invention. In that regard, reference is also made to the descriptive part and the protective rights claims 1 to Third
