1. A bag-in-box container for storing and transporting liquids with a maximum safety tap for direct consumption or consumption through flexible tubes, wherein the container comprises a flexible bag with a high level of impermeability to liquids and gases for containing a liquid product and a stabilizing box in which the bag is housed once it is filled with the liquid product, said bag including a tap comprising:
a hollow main body, with first and second open ends, that can be covered at the end portion thereof, in two height positions;
a connector, at the first end of the main body, for coupling to the bag through another connector of a lower height, welded to the bag;
a third outlet spout, in the main body, to serve the liquid product from the main body;
two windows, at the second end of the main body, which pass through the main body;
an access hole, inside the main body, which is in fluid communication with the third spout, which is automatically emptied after each dispensation and closure;
an elastic flow interrupter, housed in the main body, and comprising a first portion, fixed by pressure internally to the main body, and another elastic portion able to deform to alternately cover and free the access hole;
an actuator element with two flanges, which can be housed at the second end of the main body, and comprising: an axially rotating bushing able to move in the main body; and a shutter fastened with the elastic element;
respective flanges, able to be actuated to move the bushing away from the closing seat, from a normal closed position to another open position in which the liquid has access to the main body;
grooves, in the main body, in prolongation of the windows, for housing the supports for the flanges, in the tap safety closed position, by means of the axial rotation of the bushing; and rotation to another level through the grooves for securing the same supports in a permanent open position for independent control of the content,
wherein the tap incorporates a second spout configured as a hollow dip tube, protruding from the coupling towards the bag, moving away from the main body, up to the proximity of the base of the connector, which, in a full container position in which the container is welded to the bag and connected by pressure to the connector after filling the bag, includes a perimeter row of corrugations in its final circle, which prevent the blocking of the exit of the content in the bag through the second spout and the third spout until the complete emptying of the container; there being envisaged that radial fins are internally configured in the third spout, in the second third of said third spout from its beginning attached to the main body, as retention means for retaining residual liquid by internal wetting, having at the end of the third spout a reduction in diameter at its end, which is turned into a circular inner edge determining retentions means for retaining said relatively cumulative wetting.
