Definitions

• the invention relates to a sanitary element, in particular a sanitary tub with a film body formed from a thermoplastic plastic board, which is provided on its outer surface with a reinforcing layer made of a pourable and / or sprayable plastic compound.
• Sanitary tubs of this type are produced in such a way that a tub body is first formed from a plastic board or film, for example from polymethyl methacrylate (PMMA), by means of a drawing process, onto the outer surface of which a reinforcing layer, for example made of a glass fiber reinforced plastic, is sprayed on, in order to meet the required requirements To achieve dimensional stability and resilience.
• the inner surface then forms the usable surface visible to the user.
• the plastic board used to manufacture the tub body is dyed through, so that in addition to pure white tubs, colored sanitary tubs can also be produced according to the customer's taste. In this way, however, only single-colored sanitary tubs can be produced.
• a disadvantage of this method is that only those patterns can be applied to the transparent plastic board that always cover only a part of the surface, as is the case, for example, with flower patterns or similar patterns, and that can only be applied in the surface areas. which are practically not subject to deformation.
• the monochrome coloring of the pattern background necessary to cover the glass fiber-reinforced polyester resin layer cannot be achieved with this method. If one subjects the initially decorated and colored plastic board to the subsequent thermal drawing process, the applied patterns would be distorted due to the zone-by-zone different material expansions and thereby lose their original shape. An applied monochrome background would be thinned out at least in the corner areas, provided that the color layer applied has the same stretching behavior as the plastic board used.
• the invention is based on the object of creating a sanitary element of the type described at the outset, which is easier to manufacture and which also offers a wide range of design options.
• the inner or user surface is formed by the film body deep-drawn from a thermoplastic plastic board, while the reinforcing layer lies on the outside.
• the solution according to the invention namely the complete coloring of the reinforcing layer, offers one Special advantage, since this makes it possible to dispense with an outer covering for covering the previously unsightly reinforcing layer.
• the effect particles embedded in the plastic mass of the reinforcing layer are either visible or translucent from the inside of the tub, so that targeted decorative effects can be achieved here.
• these effect particles embedded in the plastic mass of the reinforcement layer are immediately visible.
• the most varied optical effects can then be achieved through the size and / or coloring and / or distribution density of the effect particles embedded in the plastic compound.
• These optical effects can also be achieved if the plastic material of the tub body is not transparent but translucent, so that, for example in the case of a light-colored tub body, corresponding optical effects can be achieved by dark-colored effect particles.
• These optical effects are particularly effective when the wall thickness of the finished tub body is only a few millimeters, for example 3 mm, which has become possible with modern manufacturing processes and with the improvement in the ductility of the plastics, in particular sanitary acrylic plastics.
• the effect particles are formed by particles with a glossy surface.
• these effect particles can be formed, for example, by metal flakes, by metallized plastic pieces or also particles with different refractive index or significantly different color.
• the effect particles are formed by a color pigment.
• the plastic mass of the reinforcement layer can be colored overall.
• the solid-colored reinforcement layer can also contain special effect particles.
• the color of the color pigment in the reinforcement layer is matched to the color of the plastic board, it can be achieved that thinly drawn areas of the tub body, especially in the edge and corner areas, will not experience any color deviations, but that the color of the reinforcement layer will match the color of the plastic board the color density required for the optical impression is maintained.
• an optical color impression can be achieved by coordinating the color tone of the color pigment of the reinforcing layer, which would not be possible with a solid-colored plastic board. For example, it is conceivable to achieve a changing color impression depending on the incidence of light in the case of a white translucent plastic circuit board by appropriate coloring of the reinforcing layer, for example in a darker color.
• a solid-colored reinforcement layer is that the reinforcement layer itself can also be colored on its outer surface, so that, on the one hand, the previously very "technical" looking outer surface of sanitary tubs is designed to be more visually appealing, which is also the case in presentation in salesrooms or exhibitions more attractive decorations of bathtub models allowed without these having to be fully assembled.
• the tub boxes and / or the so-called supporting frames it is also possible with tubs colored in this way to set them up in such a way that the outside of the tub is also visible. This is particularly possible and advantageous if the reinforcing layer is applied by injection molding. This method results in a smooth and visually appealing surface of the outer surface, which allows such a layout for unusual interior design.
