<p>PURPOSE:To inhibit undesirable peeling-off of a cover film from a blister package upon distribution and display of packaged articles and enhance easy peeling of the cover film upon use, by pressing a plastic film of the package and the cover film together between an iron plate and a retaining plate having protrusions of spot pattern on its pressing face. CONSTITUTION:An iron plate 10, which functions as a heating slab, and a retaining plate 11 are arranged so as to come into pressure-contact with each other. The retaining plate 11 may be made of suitable material such as wood. Into the retaining plate is fitted a recessed part 2 of a lower package 1 which s made of plastic film and within which an article to be packaged is received. An upper surface of a peripheral flat part of the package, which surrounds the recess part, is coated with an adhesive 4 on which an upper cover film 3 is rested so as to cover the recessed part. Then, the iron plate 10 is pressed on the retaining plate so that the peripheral part of the lower package and the upper cover film are interposed therebetween and heat-fused together. A brass plate 11a having a plurality of protrusions on an upper side thereof may be disposed between the peripheral part of the lower package and the retaining plate during pressing operation. In this case, the plastic film of the peripheral part is partially buried into the cover film in a spot pattern to facilitate a connection therebetween.</p> |
