Abstract
Disclosed is an improved sealing sheet for use to close 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 thus defining a container that is surrounded by a flange that is part of the top surface of the container-defining sheet. This improved sealing sheet has a top layer with tearing lines punched therein in such a manner and position as to extend from one side of each cover piece that may be splitted from the sealing sheet to cover one of the cavities in line with opposite sides of a bottom piece left on the corresponding cover piece. Such facilitates peeling of the bottom piece and of the corresponding part of the cover piece from the corresponding container to have access to the element(s) stored in it while preventing glue to be left on the flanges that surround the top opening of the container since such flanges are then still covered by non splitted parts of the sealing sheet.
