ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a metering spout-cover assembly, specifically designed for paint vessels and the like.
As is known, metering spout cover to be applied to paint vessels and the like by clamping systems usually engaged with an edge or rim flange, are already known.
The edge flange, in particular, is arranged at the top face of the vessel and defines the cover application region, for pressure closing the vessel.
The above mentioned vessels, however, are affected by several drawbacks, due to the fact that the mentioned edge flanges can have different sizes, and, because of this, the engagement region width being undesirably modified.
Moreover, it is difficult to provide a perfect sealing, since the locking region is not coherently defined and/or is limited to few points.
SUMMARY OF THE INVENTION
Accordingly, the aim of the present invention is to overcome the above mentioned drawbacks, by providing a metering spout-cover assembly, specifically designed for paint vessels and the like, allowing to assure a perfectly sealed coupling between the cover and vessel, independently from the specific configuration of the vessel.
Within the scope of the above mentioned aim, a main object of the present invention is to provide such a metering spout-cover assembly which can be firmly applied to the vessel without causing localized deformations or damages to the vessel, thereby always providing a very good sealing, independently from the specific sizes of the vessel edge flange.
In this connection it should be pointed out that a damage to a prior metering spout-cover assembly would cause a removal of the vessel protective coating, with a consequent formation of rusting and spoiling of the paints or products held in said vessel.
Yet another object of the present invention is to provide such a metering spout-cover assembly which, owing to its peculiar constructional features, is very reliable and safe in operation.
Yet another object of the present invention is to provide such a metering spout-cover assembly which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a metering spout-cover assembly, for paint vessels and the like, comprising a cover body including a metering spout, affected by a guillotine type of closure element, characterized in that said metering spout-cover assembly comprises an adapter ring, which can be removably coupled to the outer surface of a said vessel and the like, and defining, on an outside thereof, a thread for coupling the cover body.
