Comprises a top laminar wall (1), a bottom laminar wall (2) and a perimeter laminar wall (3) which extends between the top and bottom laminar walls (1, 2) delimiting a closed compartment (4), containing a flowable material, and at least one weakened area (6) formed in the bottom laminar wall (2) adapted to be broken by deforming the compartment (4) by applying a sufficient external force in order to pour said flowable material inside a container (8). There are envisaged one or more support configurations (5) formed in said top (1), bottom (2) or perimeter (3) wall and suitable for preventing said compartment (4) from being squashed or warped, when said containing lid is placed with one of its walls resting on a surface or superposed to another lid.
