A liquid applicator is provided which is particularly useful in applying preoperative surgical scrubs or paints to skin. The liquid is contained in a frangible ampoule inside the body of the applicator. This ampoule is supported and protected by a deformable element that prevents unintentional breakage of the ampoule from impacts during storage and handling before use. The applicator is actuated by pushing at least a portion of the frangible ampoule through an aperture in the deformable element and into contact with a means for breaking the ampoule.

An article useful as a dispenser for the application of liquids contained within a rupturable reservoir container to a surface, comprising: (a) a hollow elongate member dimensioned to contain the rupturable reservoir container and having a first major orifice at one end thereof; (b) deformable means contained within but not affixed to said hollow elongate member adapted for supporting the reservoir container within the hollow elongate member until the liquid is to be dispensed, and having an aperture through which at least a portion of the reservoir container may be pushed; (c) means for limiting the axial displacement of the deformable means while at least a portion of the container is pushed through the aperture in the deformable means; and (d) means associated with said hollow elongate member for rupturing the reservoir container after at least a portion of the container is pushed through the aperture in the deformable means; wherein the deformable means is a collar comprising a rim having a plurality of cantilevered beam elements projecting radially from the same lower edge of the rim into the aperture and at substantially a right angle to the edge of the rim, the inside edges of the cantilevered beam elements defining the aperture, wherein the deformable means is structured such that when the beam elements exert a critical bending moment upon the rim, the rim deflects to allow at least a portion of the reservoir container to pass through the aperture and contact the means for rupturing, which deflection is independent of reservoir diameter.
