Definitions

• the present invention relates to the field of machines for the processing of fluid products.
• the invention was developed with particular regard to a machine for measuring and dispensing fluid products, in particular fluids that are constituents of finished products such as varnishes, paints, inks, enamels, dyes for the textile industry and the like, but also of intermediate products such as, for example, colorants, pigment concentrates, colorant concentrates, pigment pastes and the like.
• a base fluid product for example white in colour or transparent
• one or more colorant fluid products in predetermined proportions according to specific formulations.
• the known machines used in the field indicated above are arranged to deliver known amounts of colorants into containers, vessels, cans or drums of predetermined capacity, in which the base fluid products have been previously placed.
• the bases are customarily stored inside vessels closed by a lid and which, at the required moment, are placed on a support platform of the dispensing machine, beneath the delivery nozzles, after the lids have been removed.
• This operation manually, there is the risk of spilling part of the contents of the vessel either before or after the operations of dispensing the colorants .
• the operations of manual opening and closing of a vessel involve a significant loss of time.
• One of the main aims of the present invention is that of obtaining a finished product, and in particular varnishes, paints, inks, enamels, dyes for the textile industry and the like, starting from a base product contained in a hermetically sealed container, by adding one or more fluid colorant products in predetermined proportions and according to specific formulations, without any operator and/or user coming into contact with any of the constituents used to obtain the finished product.
• Another aim of the present invention is that of allowing the use of any type and brand of products constituting the finished product, contained in any type of container, of any shape and size, provided that it comprises means for identification of its contents.
• another aim of the present invention is that of providing a system capable of guaranteeing absolute compatibility between the base components selected by the user and the fluid colorant products used within the automated colorimetric machine of the present invention.
• One of the main advantages of the present invention lies in the fact that any final user is capable of obtaining a finished product such as varnishes, paints, inks, enamels, dyes for the textile industry and the like, rapidly and simply, without any effort and deciding with complete autonomy on the type of finished product from among a wide choice of products obtainable.
• Another advantage of the present invention lies in the fact that the automated colorimetric machine can be installed directly at the points of sale and/or in wholesale distribution without the need for a specialised operator to help the final user to obtain the desired finished product.
