Definitions

  • This invention relates to an applicator device for a contajner for pasty materials, and more particularly to a spreading device for a collapsible tube used for a pasty shoe dressing.
  • Applicator devices are well known which include a cylindrical pad of cellular plastic having a central supply passage for the paste contents of a dispensing container. These applicator pads are supported by a rigid holder which screws onto the container. A cap to prevent drying out of the material usually accompanies such an assembly.
  • a novel spreading pad of cellular rubbery material constructed to provide a plurality of spreading surfaces when the pad is pressed or wiped against a surface to be coated and automatically to cover these spreader surfaces to retard drying and stiffening of the material when the pad is not in use.
  • the spreading device of the present invention includes a resilient pad of cellular rubbery material secured to a base which is in turn secured to a dispensing container to supply material to the surface of the pad.
  • the distributing end surface of the pad is provided with sharp incisions penetrating to a certain extent into the pad and subdividing it into separate flexible elements.
  • FIG. 1 is a side elevation with par-ts broken away of a shoe paste tube and an applicator cap showing one embodiment of the present invention
  • FIG. 2 is a plan view of an applicator pad of FIG. 1, with the cap removed showing the spreading surface of the pad;
  • FIG. 3 is an enlarged side elevation with parts broken away and the cap removed :of the applicator of FIG. 1 as deformed when pressed against a surface in use;
  • FIG. 4 is an enlarged side elevation with parts broken away and the cap removed of the applicator pad of FIG. 1 after use;
  • FIG. 5 is a side elevation with parts broken away of another embodiment of a shoe paste tube and an applicator cap according to the present invention.
  • FIG. 6 is a plan view of an applicator pad of FIG. 5 with the cap removed showing the spreading surface of the pad;
  • FIG. 7 is a side elevation of a further embodiment of an applicator pad according to the present invention.
  • the applicator pad 10 of the present invention in the embodiment shown in FIGS. 1 and 2 is a cellular plastic material, the cells of which are wholly or partly separated from each other so that the pad does not absorb the paste.
  • the plastic material may be any resilient cellular natural or synthetic rubber or cellular resin, such as polyethylene, polyvinyl chloride or polyurethane cut into a thin cylindrical shape. Resilient polyurethane closed cell foam is a preferred material since it is not affected by the solvent content of shoe paste.
  • the pad 10 is shown adhesively secured to a base 12' which is in turn provided with suitable means for securing it to a dispensing container.
  • the securing means is a threaded section 14 for co-operation with the threaded neck 16 of a collapsible tube 1 8.
  • the pad 10 may, however, be secured to any type base either permanently or separately attached to the paste container.
  • the pad 10 is provided with a central supply passage 2t) communicating with the opening in the bottom of the base 12 and with the opening in the nipple 22 of the tube 18.
  • a removable cover 24 provided with a central pin 26 which extends through the supply passage 20 of the pad sealing it when the tube is covered.
  • the pad 10 is provided with a number of sharp incisions 30 extending down into the body of the pad and dividing it into separate elements 32 separated from each other.
  • the separate elements 32 of the pad 10 will be bent and, as shown in FIG. 3, the walls 36 of the elements 32 are exposed as spreader surfaces 28 resiliently pressed against the surface 34 to be coated.
  • Paste supplied through passage Zil is spread by the surfaces 28 in a veryeffective manner.
  • the flexibility of the separate elements3 2 of the applicator surface 28 of the pad 10 adapts itself to a surface to be treated so that even diflicult over-all portions of the surface may be treated.
  • the applicator sur-fa'ce 28 of' the pad 10 is provided with two sets of incisions 30 being equally spaced and intersecting one another substantially at right angles.
  • the separate elements 32 formed by these intersecting incisions 30* will have rectangular cross-sections which are easy to bend out when the applicator surface 28 is subjected to pressure to expose the side walls 36 as a spreading surface, as shown in FIG. 3.
  • the multitude of separate elements have great elasticity, regaining their original shape quickly.
  • the walls 36 serving as spreader surfaces 28 of the elements 32 come together when the spreader is not in use, so that the surface 34 in an even and thin layer.
  • the incisions 30 have the form of circles extending concentrically with the supply passage 20 or the outer circumference of the pad.
  • the separate elements 32 are thus formed as annular lips which under pressure bend to expose the walls 36 of the elements and increase the "effective surface area of the pad 11.
  • the elements 32 are returned to their initial position by the elasticity of the pad and most of the paste is pressed out.
  • the applicator surface 28 of the pad 11 shown in FIGS. '5 and i6 is concave, forming 'a cavity 38 having its greatest height at the center of the pad, i.e., at the mouth of the supply passage 20.
  • the cavity 38 encloses the amount of paste that is pressed out through the supply passage 20 and when the pad 11 is moved over the surface 34 to be treated the amount of paste enclosed in the cavity 38 is brought along.
  • the edge of the pad because of the flexibility of the concentrically. separate portion closely adapts itself to the surfaces 3-4 to be treated, preventing the paste from flowing out, and at the same time distributing it across the surfaces in an even and thin layer. 7
  • the incisions 30 of the applicator surface 28 of the pad 11 are formed in such a way that the flexibility of the separate elements 32 increases towards the edge of the pad. Also, since the pad has an over-all thickness of from approximately 7 inch to ,6 inch, the incisions should be at least one-third the depth of the pad, preferably at least about A; inch to furnish effective flexibility. In the pad 11 having a concave surface the flexibility is preferably achieved by giving different incisions, such a depththat they terminate in a planeparallel with a plane through the exterior edge of the pad 28.
  • the depth of the incisions 30' can decrease towards the center of the pad, as shown in FIG. 7. Since the center of the pad receives the greater pressure, the incisions at the center will be more nearly completely deformed,
  • the paste is squeezed through the supply passage 20 to the surface 28 of the pad 10*, 11 or 40 and the pad'is wiped over the surface 34 to be treated.
  • the paste covers the spreading surface area 28; the total area being increased by the Wall surfaces 36 of the flattened incisions 30.
  • the flexible elements provided at the edges of the spreading surface conform to awkward areas oflered by the treated surface 34, preventing the paste from flowing out and at the same time distributing it across After use, the pad conforms to its original undistorted shape and is capped while not in use. The pad remains soft and pliable, since any residual paste retained on the walls of the spreader elements does not harden. 7
