Abstract: This is an applicator for applying a viscous fluid to a surface. There is a flexible backing material of a closed-cell material and a flexible dispensing material of an open-celled material disposed over and carried by the flexible backing material. The open-celled material has an internal structural spacing sized relative to the viscosity of the fluid so as to absorb and allow the fluid to slowly pass therethrough. Preferably, the flexible backing material and the flexible dispensing material are sealed together about the periphery thereof to form a hollow pocket. The fluid in the form of a gel, salve, or the like, is disposed in the hollow pocket. The pocket can be filled with an oxidizing agent and used for tooth whitening and/or gum treatment. The pocket can be attached to an adhesive backing to make adhesive bandages which apply various medications to the underlying skin area. This approach can be employed for treating wounds and blemishes.
