An applicator adapted for storing and spreading pre-measured portions of liquid, gel, creamy, low-melting semi-solid or solid substances on surfaces is disclosed. The applicator has a rigid base and a thin flexible cover attached to one side of the base to form, together with the base, a collapsible pocket for storing the substance. A handle is attached to the other side of the base. The thin, flexible cover includes one or more apertures wherethrough the substance contained in the pocket may flow out of the pocket. A protective sealing member, such as a thin film, is removably attached to the exterior of the flexible cover to seal or protect the apertures until the sealing member is removed from the cover. The flexible cover collapses as the substance is squeezed out of the pocket while it is being applied to a desired surface. When the substance contained in the applicator is a low-melting solid or semi-solid, the substance melts or becomes flowable as it comes into contact with a warm surface on which the substance is to be spread.

A dispenser-applicator for dispensing a substance contained therein to a receiving surface and for spreading the substance on the receiving surface, the dispenser-applicator comprising: a substantially rigid base having a generally continuous smooth surface grippable handle means; and a thin flexible substantially impervious plastic film sealed to the base so as to form a sealed collapsible pocket between the film and the surface of the base for containing the substance; wherein the thin flexible plastic film is adapted to contact the receiving surface and has at least one aperture for dispensing the substance therethrough and onto the receiving surface by application of pressure on the base to collapse the pocket between the surface of the base and the receiving surface; wherein the film is positioned on the base such that as the pocket collapses the film moves toward the surface of the base and wherein the film is sufficiently thin and flexible such that (a) the film itself provides no significant resistance to the pressure applied to the base and essentially all pressure applied to the base transfers to the substance in the pocket, (b) the film conforms to the shape of the substance in the pocket when pressure is applied and remains in the shape of the substance in the pocket when the pressure is released and (c) the film distributes the applied pressure over the receiving surface and spreads the substances on the receiving surface of the dispenser-applicator is moved across the receiving surface.
