Problems solved by technology

This creates a build-up of dirt and dry residue that impairs the performance of the delivery head and does not guarantee that all of the fluid delivered will reach the underlying primer because some of the fluid will inadvertently be sprayed onto adjacent needles, presenting Risk of contamination of colorants delivered by adjacent lancets
Especially in the case of formulations of coloring products that require high precision in the dosage of their various components, this can lead to the formulation of the final product without the expected quality characteristics

Embodiment Construction

[0042] With reference to the accompanying drawings, the disclosed injection lancet 10 is used on a machine for automatically conveying, dispensing and / or dispensing a fluid product such as a coloring product, capable of introducing a dose into a container containing a primer Coloring pigments to obtain the desired coloring products. refer to Figures 9 to 12 , specifically, the machine usually includes a transfer head 30 on which a plurality of needles 10 are installed. A machine of this type is described, for example, in the cited European patent application EP'830 in the name of the Applicant or in the Italian patent application UD2010A000126.

[0043] The container is usually provided with a closure cap which can be pierced by the lancet of the transfer head. In some embodiments, the closure cap has a portion made at least in part of a film of plastic material capable of expanding when the lancet penetrates the film for delivery and retracting again when the lancet is wit...

Abstract

An injection needle (10) for a delivery head (30) for fluid products, such as for example pigments or coloring products, inside a container containing a paint base to obtain a coloring product, comprises internally an axial hole (20) which develops along a first central axis (X) for the passage of the fluid product toward a delivery opening (23). A channel (22) is provided to connect the opening (23) with the axial hole (20). The channel (22) develops along a second axis (Y) inclined by a desired acute angle with respect to said first axis (X).

Description

technical field [0001] The present invention relates to an injection lancet for fluid products such as pigments or colored products, for example on dispensing machines. Background technique [0002] There are known dispensing or conveying machines for colored products, which introduce the required quantity of colored pigments into the container containing the primer to obtain the desired colored product. [0003] Such machines generally include a delivery head provided with a plurality of injection lancets which perform the functions of perforating the lids of the containers and injecting the desired quantity of coloring pigments into the containers. [0004] A known problem with injection lancets is the formation of drops and residues of the coloring product at the color delivery tip. These residues tend to dry out over time and greatly affect the performance of the felting needle. [0005] European patent application EP-A-2.040.830 (EP'830) in the name of the applicant d...
