摘要

The inventive device comprises a housing ( 1 ) which is configured in the shape of a flat strip comprising an enclosure ( 6 ) on one side which projects outwards and contains a material ( 7 ) that changes its state or viscosity at a predetermined temperature. Said enclosure ( 6 ) opens onto the space inside the housing through a hole ( 8 ) which can be plugged with a tongue ( 9 ), this space inside the housing containing a strip ( 11 ) consisting of a porous material that is visible form the outside through holes made on the top surface ( 5 ) of the housing.
