Abstract
A process for making a material with reflecting and refracting properties, consisting of successive steps in which a support is prepared and then treated and/or coloured with inks, paints, or other suitable products, and wherein a plurality of spheres or microspheres is then applied to said support, said spheres or microspheres being made of vitreous and/or ceramic and/or plastic material and being suited to reflect and refract the light incident on them.
Description
TITLE
PROCESS FOR APPLYING REFRACTING AND REFLECTING SPHERES AND/OR MICROSPHERES TO A SURFACE AND PRODUCT OBTAINED THEREWITH
DESCRIPTION
The present invention concerns surface treatments for materials of various type, and in particular it concerns a new process for applying refracting and reflecting spheres and/or microspheres and the product obtained therewith.
Containers are known for containing food, cosmetics and various types of materials.
Cut cardboard sheets are also known, used for making containers in general.
Packages made of rigid or semi-rigid polymeric plastic material, like PVC,
PE, etc are also known.
Plastic or glass bottles and plastic, aluminium or alloy cans are also used to contain food products or beverages.
Surface treatments for various types of materials are known, like the application of inks, enamels, paints and products in general for colouring and decorating surfaces.
Said treatments, for example, are commonly used for colouring and decorating the outer surfaces of bottles and cans for beverages or food products in general, of containers and boxes of various type and made of different materials.
The subjects of the present patent are a new process for applying refracting and reflecting spheres and/or microspheres onto surfaces, and the product obtained therewith.
The main aim of the new process is to produce a surface that reflects the light incident on it, with pleasant aesthetical effects and at the same time
reducing the absorption of radiation and therefore increasing heat insulation. Another aim of the present invention is to allow application to surfaces made of any type of material, paper or derived materials, plastic or derived materials, metallic, vitreous, ceramic materials, etc. Another aim of the present invention is to allow the use of the material obtained to make containers, boxes, and cases of various type and to make sheets and labels to be applied onto boxes and containers in general. Another aim of the present invention is to reduce heat transmission through the treated surface. A further aim of the present invention is to obtain surfaces having special and original luminous effects.
These and other direct and complementary aims have been achieved through the implementation of the new process for applying refracting and reflecting spheres and/or microspheres onto surfaces and of the product obtained therewith.
The new process consists of the following steps: preparing at least one support made of plastic, metallic, cellulosic, vitreous, ceramic material, etc.; spreading paints and/or inks and/or enamels and/or products of various type, by printing, painting, or other known techniques, on the whole or part of the surface of said support, in order to colour and/or decorate the surface itself; applying, by spraying, scattering or other suitable techniques, a plurality of spheres and/or microspheres to the whole or part of said surface, coloured and/or decorated and/or generically treated with said paints and/or inks and/or other products, and wherein the application of said spheres and/or microspheres is carried out soon
after spreading said products for decorating and/or colouring and/or after the surface treatment of the support.
In particular, the application of said spheres and/or microspheres is preferably carried out when said products for decorating and/or colouring and/or surface-treating the support are still wet, that is, before they have completely dried up, in order to ensure the adhesion of the spheres and/or microspheres.
According to a further embodiment of the invention, said spheres and/or microspheres may be previously mixed with said products for the surface treatment of said support, so that the application of said spheres and/or microspheres takes place at the same time as the spreading of said products. For the surface colouring and/or decoration, it is possible to use inks, paints, enamels or products in general in various colours, even dark colours such as red, blue, green, or light colours such as white, grey, chrome, etc. In this way it is possible, for example, to decorate and/or colour any type of container with the colours, drawings and distinctive symbols of the product contained therein, and with a surface layer of said spheres and/or microspheres. According to the invention, also transparent paints, varnishes and products can be used.
In addition to that, after said step in which paints and/or decorations of various types are applied, it may also be possible to spread binding or bonding substances, transparent, coloured or pigmented. Said binding or bonding substances have the function to increase the adhesion of said spheres and/or microspheres to the support surface, or to allow the new process to be applied also to already coloured and/or decorated surfaces.
Said spheres or microspheres are then applied, through scattering and/or spraying and/or other suitable techniques, to the surface of said support, where they adhere only to the area covered with said products for colouring and/or decorating and/or with said binding or bonding substances. According to the invention, in addition to one or more of said steps, it may also be possible to apply microscopic drops of a binding agent, paint, resin or other substance, vaporized and/or sprayed at a suitable distance from the treated surface, and said vaporization and/or spraying step may take place after the step in which said spheres and/or microspheres are applied. Said vaporization and/or spraying lends the treated surface a bronze or chromium shade, at the same time guaranteeing better adhesion of the spheres and microspheres over time.
Said spheres or microspheres are constituted by pieces of glass or ceramic and, in particular in the case of said microspheres, have typical dimensions in the order of tenths of a millimetre, or even smaller.
Also spheres or microspheres made of plastic material, with the addition of coloured pigments, if desired, may be used.
As an alternative to or in combination with said types of spheres or microspheres, also oriented spheres or microspheres may be used, that is, spheres or microspheres having a silvery hemisphere, and therefore suited to lend a chromed hue to the surface of said support.
Said support may be made of any type of material, for example plastic, PVC, PE, or aluminium or metal alloys of any type. Said support may be in the form of a sheet, or a thin film. Said support, for example, may also be a label in paper and/or plasticized material, with adhesive or non-adhesive surface, suited to be applied to the surface of objects of various type.
The present invention can be applied in particular for treating the surface of materials used for making containers, like plastic bottles or cans in aluminium or other alloys, suited to contain food products, like for example beverages. The spheres and/or microspheres that cover the surface of said containers reflect the light incident on them, considerably reducing the quantity of radiation absorbed by the walls of the container.
In this way the content, be it a beverage or a food product in general, is thermally insulated more efficiently and for a longer time, since, as already explained, heat transmission through the walls of the container is also reduced.
The new process is successfully applied for treating the surface of the known aluminium cans, as described and claimed herein, used for preserving beverages and usually coloured with dark colours such as red, blue, green, etc.
The can obtained has therefore an original, pleasant and distinctive appearance and, furthermore, ensures reduced heat transmission through its walls from the outside towards the product contained, whose temperature is usually lower than the ambient temperature. The present invention can be usefully applied also in the production of plastic containers, for example small packages for containing cosmetic products, like face powder sets, mirrors, lipsticks, etc. Therefore, with reference to the above description, the following claims are expressed.
