Definitions

  • the present invention relates to systems for helping deliver bar compositions to the skin and for helping boost lather.
  • it relates to devices for holding bars which can be used in applying the bar compositions to the skin.
  • the bar containers may be helpful for delivering consumer beneficial properties which may not be as readily available in synthetic detergent bars.
  • synthetic bars generally use surfactants which are less harsh than soap, but often provide less lather (some synthetic bars may further comprise emollient oils which actually depress lather).
  • the containers may also reduce sensory perception of mush.
  • U.S. Patent No. 5,462,378 to Webb teaches a wash cloth adapted to receive a bar of soap; and U.S. Patent No. 4,190,550 discloses pads of non-woven fibers containing a solid core of soap.
  • synthetic surfactant bars for example, bars containing 5-90%, preferably 10-80% surfactant, when used in a holder, particularly a holder made of a polymeric mesh sponge material (e.g., extruded tubular melting mesh) can remedy some of the deficiencies found in synthetic bars and not found in pure soap bars.
  • a synthetic bar particular one comprising lesser amounts of surfactants and more structurant (e.g., 5-60% surfactant, preferably 10-50% surfactant and 10-40% structurant such as polyalkylene glycol) may be a less moisturizing bar and therefore require benefit agents/ moisturizers. Often these oily moisturizing agents are lather depressants.
  • bar pouf retainer allows these relatively low surfactant, moisturizer-containing bars to be utilized without sacrificing lather.
  • synthetic bars tend to be softer/mushier than pure soap bars.
  • Use of the bar container provides sensory signals which allow the consumer to sense less mush. Lesser lather and mush perception are not problems normally associated with non-synthetic soap bar.
  • preferred tubular mesh holders provide other advantages one would expect from a nylon mesh bag such as stimulating skin with the rough material; and/or allowing bars to be readily held during the lathering experience.
  • the present invention relates to a soap bar cleansing system comprising:
  • the surfactant bar composition of the invention may comprise 5% to 60% surfactant and greater amounts of structurant relative to surfactant. In addition, it may comprise benefit agent.
  • the sponge in addition to containing/enveloping the bar, additionally has an insert which is kept in the pouf container/sponge during use of soap-in-container.
  • Figures 1-3 are picture of polymeric meshed material as a sponge (no insert) of prior art.
  • Figure 1 is a perspective representation of a diamond mesh polymeric sponge.
  • Rope handle 7 may be used for the pouf.
  • Figure 2 is a picture showing how the sponge can be held in the hand.
  • Figure 3 shows netting mesh which can be used to make the sponge.
  • a security band 13 holds the multi-layered netting mesh together to form the polymeric mesh sponge.
  • the netting mesh that can be used in making the polymeric mesh sponge is illustrated in Figure 3 wherein 21 represents the mesh in stretched position.
  • the fine polymeric filaments used in making the netting are represented by 18 with 19 representing the spot bonding of the filaments to form the open mesh 20.
  • Figure 4 is a figure of pouf "bag” of invention designed to hold a bar inserted therein.
  • the figure shows bag in closed position (bar would be inside) with drawstring pulled to close bag.
  • the bag is made of polymeric meshed material.
