Said container comprises a base, a lid (C) and a vertical partition joining the base and the lid, a tongue element comprising a grip end (4) and an opposite bearing end (8), said tongue element (4,8) comprising a lug (3), being integral with the lid (C) by means of a plug (2) fixed to the lid (C). The tongue can be rotationally displaced around the longitudinal axis XX of the plug (2) and can be inclined at a certain angle $g(a) in relation to the plane of the lid, an opening zone (1) being defined by a precut (10) in said lid (C) and being able to be opened using the tongue, whereby the bearing end thereof (8) exerts a force from the outside to the inside of the container on said area (1) defined by the precut (10). The tongue is such that the grip end thereof (8) has a closing/opening area (7) which is originally convex and which can be deformed, as a result of the flexibility and elasticity thereof, by a pushing movement from the outside to the inside of the container in order to take on a concave shape and vice-versa, being able to be deformed in order to revert to a convex shape by pressing the inside towards the outside of the container on the bearing edge. The invention can be used in containers, especially beverage containers.
