Patent ID: 7631759

Claim:
A packaging bag for a plaster, the plaster including a plaster body, a support and an adhesive layer laminated on one surface of the support and having a plaster outer periphery, and a release film having a release outer periphery and being detachably attached to the adhesive layer, the packaging bag, comprising: a pair of packaging films comprising first packaging film having a first perimeter and an opposing second packaging film having a second perimeter, the first packaging film and the second packaging film being sealed together at the first and second perimeters thereby forming an interior housing portion having a housing outer periphery for housing the plaster, the first packaging film or the second packaging film comprising a protrusion having a protrusion outer periphery and protruding into the interior housing portion and configured such that when the plaster is packaged in the packaging bag, the protrusion contacts a portion of the plaster body excluding the plaster outer periphery, the protrusion having a height such that when the release outer periphery extends outward beyond the plaster outer periphery, an outer peripheral portion of the packaging film on which the protrusion is formed is separated away from the plaster outer periphery, wherein an angle θ2 formed by a line joining the housing outer periphery with the protrusion outer periphery is greater than an angle θ1 formed by a line joining the housing outer periphery with the plaster outer periphery, so that the plaster outer periphery does not contact the packaging film on which the protrusion is formed.
