A sealing sheet for use to close in a reversible manner a plurality of individual pill containers formed in a plastic sheet. The sealing sheet has a top layer, an adhesive layer and a peelable backing. The top layer and the adhesive layer are made of paper. The adhesive layer has a plurality of spaced apart holes punched therein, which are surrounded by adhesive layer bands having an upper surface that is covered with an upper layer of pressure sensitive adhesive glue and is attached by this glue to the top layer, and a lower surface covered with a lower layer of removable re-positionable pressure sensitive adhesive glue. The peelable backing also has a plurality of spaced apart holes that are positioned, shaped and sized to be in exact superimposition below the holes of the pressure sensitive adhesive glue layer. The holes of the backing are surrounded by backing bands having an upper surface detachably fixed to the lower surface of the adhesive layer bands by means of the lower layer of removable re-positionable pressure sensitive adhesive glue. In use, the backing bands can be peeled off from the pressure sensitive adhesive glue layer bands to allow fixation of the sealing sheet onto the container-defining sheet. Tearing lines are punched into both the top layer and the pressure sensitive adhesive glue layer bands in such a manner and position as to allow the top layer and pressure sensitive adhesive glue layer to be split into a number of cover pieces equal to the number of holes made in the pressure sensitive adhesive glue layer.
