Summary for Patent: 5,538,353

Title: Liquid applicator
Abstract:A liquid applicator for applying a desired liquid to a surface includes a closed vial formed of a fracturable material containing the desired liquid, a body having a pocket with an open side and a shape adapted to receive the vial, and a porous element sealed to the body and closing off the open side of the pocket so that liquid flows through the element when the vial is fractured. The body has a flange protruding from the pocket along the open side thereof and a wing-like gripping member projects from the flange. The gripping member is spaced from the pocket and supported for pivoting movement relative to the pocket by the flange. The body also has structure for fracturing the vial, the structure being interposed between the pocket and gripping member. Upon pivoting of the gripping member, the structure flexes the pocket inwardly to exert a fracturing force against the vial when the member is pivoted towards the pocket.
