Abstract: A tubular container with a non-removable workable cap, by means of which the cap itself is provided with a limitation in its closure on the tube. To do this, the cap is equipped with a vertical rib (7) which originates from the front internal face of the cap and from its inner side surface, which is interrupted at a certain distance from the free end of the outer skirt (9) of the cap. This cap makes contact, when it is turned in both directions, with a protrusion (8) made on the tube and is limited in the closure position by an L-shaped protrusion (3) on the tube itself.
