Abstract: A sealing sheet for closing a container-defining sheet having a top surface comprising a given number of spaced apart cavities embossed therein, each of the cavities being upwardly opened and defining a container surrounded by a flange. The sealing sheet includes a top layer having a lower surface covered with pressure sensitive adhesive glue, and a bottom layer having an upper surface detachably fixed to the lower surface of the top layer by pressure sensitive adhesive glue. The bottom layer being peelable from the lower surface of the top layer to allow fixation of the sealing sheet onto the top surface of the container-defining sheet in order to close the containers defined in the same. The sealing sheet also includes an additional layer that is tearable into additional elements that are foldably attached on top of each of the containers and on which additional information may be printed.
