Abstract
An apparatus for sealing medication blister cards including a unit dose of medication in at least one, if not all, of the blisters comprising card. More particularly, the apparatus includes a card holder for receiving the filled medication card and a heated sealing head movable into juxtaposition with the top surface of the filled card so as to apply both heat and pressure to the card as it is held between the card holder and the heated sealing head. First and second ridges extend upwardly from the card holder into engagement with the bottom of the medication blister card, and the contacting surface of the heated sealing head is knurled. Accordingly, as the card is held and heated between the card holder and the sealing head, the application of pressure and heat not only seals the card, but also the ridges and knurling effectively form channels whereby moisture present in the card is expelled therefrom and condenses on the card holder.
