Bowls at the current time are made of wood, special forms of stone, ivory, or sawdust mixed with adhesives and plastic. Round Multicolor Plastic Bowls are made either by creating a cover which is then filled with water under pressure or by moulding a plastic full of sawdust. In the case of a plastic filled with sawdust, hygroscopic difficulties are created owing to the plastic material used heretofore. The multicolour plastic bowls of the state of the art entail glitches of dimensional stability, impact strength, hygiene, healthy circumstances and toxicity owing to the type of plastic used hitherto.
Moreover, the multicolour plastic bowls of the state of the art do not fulfil the necessary weight/dimension ratio and are therefore only used for improvised sports activities of a family type. In fact, with a low weight/dimension ratio a bowl does not own enough inertia to hold its direction and any small bulge in the ground is enough to stray its path.
Advantages of using the Round Multicolor Plastic Bowl
Formability:
Plastics are very good materials when it comes to high formability. Plastics can be moulded, cast, rolled, forged, stamped, and extruded, and so on. They can be shaped into complex shapes, comprising those that are difficult or unbearable for other materials. The dies and tools used to form plastics are also cooler to make. Creating multicolour plastic bowls does not require as much pressure as that forming glass or metal containers.
Resists degradation from chemicals and water:
Multicolour plastic bowls do not rust or degrade the same way as metals. Metals grow rust, which weakens the structural integrity of the bowl. Rust also poses the threat of product impurity, particularly for food and pharmaceutical products. Only a few materials can associate with the degradation resistance of plastic. One instance would be glass which has many limitations when used as multicolour plastic bowls.
Light Weight:
Plastics have masses of around 0.8 to 1.5 times that of water. Steels have densities of about 7.8 times while glass and ceramics are nearly 2 to 3 times. This shows that plastics are considerably lighter than metals and glass used for the same use. Moreover, some plastics are caused to have a high strength-to-mass ratio. Multicolour plastic bowls made from these plastics have thinner walls, further reducing their mass.
Flexibility and High Strength:
Multicolor plastic bowls can be made from different kinds of chemicals through various procedures. Each type of plastic has essential mechanical properties. These properties are altered by compounding distinct additives that can progress its flexibility and strength. Samples of these additives are glass and carbon fibres. Tallying fibres into a plastic matrix makes a composite material with better tensile and flexural strength
High Impact and Tear Resistance:
Plastics are made from long, bound molecules that position themselves in crystalline or amorphous structures. Their structure gives them essential elasticity, so plastics do not fail effortlessly through brittle fracture and cracking. Tearing is an issue determined by comprising additives or by using a polymer base with high tensile strength.
Good Aesthetics and Surface Characteristics:
The appearance of plastic multicolour bowls is fully customizable. Multicolour plastic bowls can be made into clear, translucent, or fully opaque products. These can also have various colours by adding pigments. When it comes to surface characteristics, plastics can have a variability of finishes and textures without using costly secondary operations.
Long Service Life:
Because of their chemical and wear resistance, multicolour plastic bowls do not damage easily under normal conditions. This gives them an extended service life. Some plastic additives additionally improve their durability by imparting resistance to oxidation and ultraviolet radiation. When not managed correctly, they can rapidly accumulate and harm ecosystems.
Recyclability:
Like glass and metals, multicolour plastic bowls can be recycled. Usually, plastics are recycled overheating and melting. By heating, plastics are melted and shaped into raw materials for manufacturing new plastic products. However, melting is only appropriate for thermoplastics. Progressive procedures are also being developed; usually, these methods chemically convert plastics into monomers that are used as fuels for power generation.
Low Production Cost:
Multicolour plastic bowls are easy to form and need less energy to produce than metal and glass containers. Plastics are effortlessly shaped when heated, needing only a moderate amount of pressure. Plastics can even be shaped by compressed air. The temperature of its melted state is not as extreme as metals and glass. Plastics in this state can be injected and moulded without the necessity for expensive dies and tools.
Things to consider while manufacturing the round multicolour plastic bowl
-Produced plastic bowls which are not only non-toxic and hygienically appropriate but which possess the desired weight.
-Also, dimension ratios, are resilient to impacts and humidity and are of a professional or semi-professional type.
-The present applicants have carried out wide work in research, experiments and selection until they found an appropriate basic plastic material which has never been engaged hitherto in these products owing to the understood difficulties of its use which formerly discouraged its employment.
-The applicants have also been capable of faultless the relative production method for making the bowls.
-The method to produce round multicolour plastic bowls and the relative plastic bowls are outlined in the relative main claims, while the reliant claims describe variants of the idea of the key solution.
-The invention empowers bowls of a semi-professional or professional kind to be produced directly without mechanical finishing processes.
-Polypropylene is employed as a basic plastic material to overcome difficulties of toxicity, resistance to humidity, ability to resist impacts and also dimensional steadiness to possess a good weight: dimension ratio.
-The basic material containing polypropylene is filled with one or another, or with a combination of two or more, of the next additives: powdered wood, combinations of elastomers, talc, fibres, mineral powders or equivalents.
-Polypropylene, even when thus filled, has good compatibility with the skin and with the mucous membrane and is physiologically innocuous. Furthermore, it does not lose its particular qualities identified by the present applicants. This fact allows bowls to be produced which can be held by anyone, even children.
