Abstract:
The present face mask may have a double seal, a triple seal or a quadruple seal, with distinct spacing between each of the seals within a set of seals. Each of the seals within a double seal, triple seal, or quadruple seal may stand alone or may be interconnected to other seals by bridging, where such bridging is formed of the same adhesive as the seal itself. Also disclosed is an after market embodiment where a multiple seal by itself is housed between two sheets of release paper to be applied to a face mask by the user himself when needed. Further disclosed is a multiple seal with bridging applied to a clothing combination, such as to seal sleeve cuffs to a glove.
