  • Patent number: 4101053
    Abstract: A hand-held, generally T-shaped disposable product applicator and a dispensing package therefor. The applicator comprises a resilient applicator pad portion and an upstanding finger grip portion. The applicator pad portion is normally substantially planar with a top surface and a bottom product applying surface coated or impregnated with the product to be dispensed. The upstanding finger grip portion is normally substantially planar with its sides providing finger grip surfaces. The finger grip portion is substantially normal to and extends transversely across the top surface of the applicator pad portion, bisecting the applicator pad portion into two substantially equal flaps. The applicator pad portion is foldable along its juncture with the finger grip portion with its bottom product applying surface folded upon itself.

  • Patent number: 4067087
    Abstract: Procedures for continuously forming rosette shaped tampons from aggregate containing tubular sacks or overwraps having withdrawal strings at one end and assembling the tampons in inserters, rotary transfer mechanism being provided for engaging the withdrawal strings of the sacks and sequentially delivering them to a rotary assembly turret having a multiplicity of assembling stations mounted around its periphery. Each inserter comprises inner and outer parts, and feeding means are provided to individually feed and position an inner inserter and an outer inserter in holders at each assembly station. Each station has a reciprocating string engaging rod which acts to remove a sack by its string from the transfer mechanism and positions the sack to be drawn upwardly by vacuum into an overlying annular inversion chamber wherein the sack is inverted into rosette shape by the action of a pressure-vacuum reciprocating inversion rod.

  • Patent number: 4014616
    Abstract: Hand-held, generally T-shaped product applicators and a dispensing package for a stack thereof. Each applicator comprises a body portion and a handle portion. The body portion is dish-shaped with a convex bottom surface and a concave top surface. The bottom surface may be used directly to apply a product, or it may be provided with a product-applying facing. The handle portion is hollow and constitutes an integral, one-piece part of the body portion, extending upwardly from the top surface thereof. The hollow handle portion is open at the bottom surface of the body portion and closed at its top with upwardly and inwardly sloping edges and upwardly and inwardly sloping sides providing finger-grip surfaces.
