Abstract

Improvement in a pouring spout for liquids of various viscosities comprising a small tube with adequate diameter and length (1) presenting its distal extremity curved in a cuneiform angle (2) forming a pouring mouth (3), oval or elliptical, angularly oriented downwards, which larger axis (4) extends longitudinally along with such small tube (1) so that its superior extremity or superior distal edge (5) is extended outwards and its inferior opposite edge (6) is retreated backwards.

Claims

1. ) NON-DRIP SPOUTS FOR LIQUIDS OF VARIOUS VISCOSITIES, subject to be used in rigid, semi-rigid or flexible containers, for commercial, industrial and domestic use, characterized by comprising a small tube with adequate length and diameter (1) presenting its distal extremity bended or curved in cuneiform angle (2), the tube (1) can be chamfered in several angles (α

) as to form an oval or elliptical, angularly oriented downwards pouring mouth (3), in the curved portion of the spout, which larger axis (4) extends longitudinally along with said small tube (1) in a way that its superior distal extremity or edge (5) is extended outwards and its inferior opposite edge (6) is retreated backwards;

wherein angle (α

) created by the chamfer, between the plane of the mouthpiece (3) and the vertical edge of the distal tip (5) is always less than 90 degrees.

2. ) NON-DRIP SPOUTS, according to claim 1, characterized by the fact that the tube (1) is curved or bended in an angle varying in between 0 to 90 degrees in relation to the axis of the spout inlet mouthpiece through where the liquid enters.

3. ) NON-DRIP SPOUTS, according to claim 1, characterized by the fact that the pouring mouth (3) area and shape vary as a function of the chamfer angle and the curvature of the tube (1).

4. ) NON-DRIP SPOUTS, according to claim 1, characterized by the fact that, in its dimensioning, there is a correspondence between the angle of the spout in relation to the axis of the straight part or of the spout inlet mouthpiece which is inside the recipient (a) and the angle of chamfer of the pouring mouthpiece (b):

“

the larger are the angle (a), more are the possibilities for the chamfer angle (b)”

5. ) NON-DRIP SPOUTS, according to claim 4, characterized by the fact that for a liquid of specific viscosity there is one or more specific values of (a) and (b) that do present better performance.

6. ) NON-DRIP SPOUTS, according to claim 1, characterized by the fact that the pouring mouthpiece (3) presents almost no thickness, and the finishing of its entire perimeter is sharp-edged (blade).

7. ) NON-DRIP SPOUTS, according to claim 1, characterized by the fact that the distal extremity (5) may or may not be rounded (8).

8. ) NON-DRIP SPOUTS, according to claim 1, characterized by the fact that the curvature (C) or bend (D), wherein the pouring mouth (3) is located, may or may not be preceded by a straight part with any length (7).

9. ) NON-DRIP SPOUTS, according to claim 1, wherein it is characterized by the fact that the spout herein has its base or extremity opposite to the pouring mouth (3) with any geometry.

10. ) NON-DRIP SPOUTS, according to claim 1, wherein it is characterized by the fact that its base or extremity opposite to the pouring mouth (3) includes any complement of grooving and fixation to the local of use, and can even be an integrating part, or not, of a stopper, lid or something similar.
