Definitions

  • This invention relates to a method of strongly attaching a bar or cake of solid detergent to a synthetic sponge and relates also to sponges combined with detergent bars or cakes so elfectively that they are not separated during washing use, even when the detergent has been substantially completely consumed.
  • a process for attaching detergent material to synthetic sponge comprises applying to a bar or cake of solid detergent material selected from the group consisting of Water soluble soaps of higher fatty acids, water soluble synthetic organic detergents and mixtures thereof, a Water insoluble adhesive, a Water impermeable barrier, held to the detergent material by the adhesive, additional water insoluble adhesive and synthetic sponge, the additional adhesive holding the water impermeable barrier to the synthetic sponge, pressing the sponge against the detergent bar and maintaining it in position pressed against the bar, for a sufficiently long time to hold the water impermeable barrier tightly against the detergent with the adhesive covering and adhering to substantially all the contiguous Water impermeable barrier and detergent bar surface.
  • a combination synthetic sponge and detergent cake comprises a cake of detergent material selected from the group consisting of solid water soluble soaps of higher fatty acids, water soluble synthetic organic detergents and mixtures thereof, a water impermeable barrier held to the detergent by a Water insoluble adhesive and a synthetic sponge fastened to the water impermeable barrier.

  • the pressed cakes 33 are then barrier units -41 and are fastened to them.
  • a further are pre-indexed'sponge-barrierfunits.
  • the spongebarrier combined units are formed by applying a barrier film to a strip of sponge with adhesives applied on both sides of the lm.
  • a roll 43 or other continuous length of sponge in strip form 45 is unrolled and fed past a feeder 47 for adhesive and a doctor blade 49 to distribute the adhesive evenly in a layer of desired thickness.
  • a strip 51 of lilm barrier of the same width as the sponge is unrolled from a reel and is brought into superimposition with the sponge.
  • a pressure-sensitive adhesive is applied by feeder 53, and is doctored by blade 55 to correct thickness andcomplete coverage.
  • a backing 57 of smooth paper or other suitable material is then joined to the combined sponge and barrier. It covers the pressure sensitive adhesive andV later acts to support and index the Sponges to be applied to detergent cakes, but it is readily stripped from the barrier film when desired, without tearing.

  • the barrier can be separated from the sponge, if so desired, but in normal careful use they will remain attached.
  • the pressure sensitive adhesive coated barrier will remain clean looking and will not pick up dirt, when wet. It will serve to hold the spongey together and will help to prevent its disintegration during use. Still, the adhesive will allow the sponge to be easily adhered to dry surfaces, such as walls or sinks.
  • the sponge which may be combined with the detergent cake is substantially water insoluble and resilient. It is preferably very light in weight, much less than the density of water, and contains an interconnected cellular network the cells being filled with gas, usually air. With this structure the sponge is able to take up moisture throughout its body, when it is collapsed by pressure, expelling the air, and then released, allowing replacing of the air by wash water. Such continuous compression and expansion of the sponge face facilitates the mixing of air and detergent solution in films and promotes the development of a copious foam.
  • the small interconnecting cells of the sponge are substantially uniform in size to the eye and generally range from 0.005 to 0.100 inch.
  • the material of which the sponge is made should be dimensionally stable and little affected by the presence of moist or dry conditions, insofar as expansion and contraction are concerned. Suc-h a sponge will not tend to warp or distort during use due to alternate moistening and drying of the detergent cake and Will not tend to pull away from the surface of the detergent. It is also desirable for the mate rial of the sponge, itself, to be relatively non-absorbent, to promote faster draining and more rapid drying of the product.
  • suitable sponge materials are the various synthetic products, especially those based on substances commonly referred to as plastics. Natural animal sponges do not have the properties or structure tol be suitable in the invented combination article.
  • cellulose Sponges may not vbe used because their dimensional' instability and capillary action make them less suitable than other synthetics.
  • Sponges useful in this invention there may be mentioned those made by foaming rubber, either natural or synthetic, as Well as Sponges Vmade by foaming resilient plastics such as poly-ethylene, poly-esters,
  • polyvinyl chlorides and acetates and other compounds of similar properties are those made from polyurethane, preferably of the polyester type for harder and medium Sponges and of the polyether type for those desired to be softer. These Sponges are of good color, high resiliency, low water absorption and possess surfaces which in ordinary usage contribute an excellent massaging action on the skin without irritation. These polyurethane Sponges do not lose their desirable tactile properties when wet. As with most plastics the polyurethanes are available in a Wide variety of colors which contribute toward the esthetically pleasing appearance of the combination soap and sponge. In the molding or trimming process the polyurethane sponge may be shaped to include a trade name or decoration which, unlike the case with soap alone, will not be removed as the product is consumed. If desired, the Sponges may be printed instead.
  • the detergent material which is a part of the invented article of manufacture is an organic detergent which may be selected from the group consisting of higher fatty acid soaps and water soluble synthetic organic detergents. Mixtures of soaps, mixed synthetic organic detergents and soap-synthetic organic detergent combinations may be employed. These materials are water soluble and normally solid so that they are suitable for manufacture in bar and cake form.
  • anionic or non-ionic there may be mentioned the fatty alcohol sulfates, fatty acid monoglyccride sulfates, sulfated oxyethylated fatty alcohols, alkyl aryl sulfonates, alkyl sulfonates, higher fatty esters of isethionic acid, higher fatty amides of taurine and N-methyl taurine, higher fatty amides of sarcosine, higher fatty sulfo-acetates and sulfated higher fatty alkylolamides.
  • anionics there may be mentioned the fatty alcohol sulfates, fatty acid monoglyccride sulfates, sulfated oxyethylated fatty alcohols, alkyl aryl sulfonates, alkyl sulfonates, higher fatty esters of isethionic acid, higher fatty amides of taurine and N-methyl taurine, higher fatty amide
  • the higher alkyl and acyl groups mentioned in the above description are those containing 8 -to 20 carbon atoms, preferably l2 to 18 carbon atoms. Usually it is preferred that the carbon atoms of the acyl and alkyl groups should be in straight line configuration but often, ⁇ as in the case of the alkyl benzene sulfonates, branch chain groups may be employed in limited minor amounts. All the anionic synthetic organic detergents are used as water soluble salts, preferable as alkali metal salts.
  • Alkaline earth metal salts, ammonium salts, triethanolamine salts and others may also be used but the salts of sodium and potassium, especially the former, are preferred because they usually possess better water solubility and are of suicient hardness to be made into a cake product.
  • the higher fatty acid soaps are those which are Water soluble and normally solid. Such soaps are usually of 8 to 20 carbon atoms and are obtained by saponication of the usual soap making oils such as coconut oil, tallow, hydrogenated coconut oil and tallow, lard, grease, babassu oil, palm oil, palm kernel oil and other well-know materials of similar types.
  • the soaps are usually made in the forms of their sodium salts although other alkali metal salts such as those of potassium may also be found to be satisfactory.
  • Triethanolamine soaps or soaps of other organic bases can be used but are not usually as efficient .as those of sodium.
  • the alkaline earth metal soaps and the magnesium soaps are not included within the scope of water soluble higher fatty acid soaps, although these materials may be added to the bar cornpositio-n as fillers or for other purposes.
  • Normally solid water soluble non-ionic detergents are those which usually contain chains of lower alkylene oxide to increase their hydrophilic properties. Included in this group are the higher fatty acid esters of polyoxyethylene alcohols ethylene oxide-propylene oxide block copolymers of higher molecular weight, eg., 5,000 to 20,000, ethylene oxide adducts of lower di-alkyl phenols, other polyalkoxylated lipophilic stems and higher fatty esters ⁇ of multi-hydroxy compounds such as sugars, polyglycols and so forth.
  • barrier Between detergent and sponge is a barrier, usually in thin film form. This barrier should be thin enough to be resilient and flexible so that it will not easily be pried loose from the detergent and sponge to which it is fastened. ⁇
  • the barriers that have been found to be most use- .ful are those made from synthetic organic plastics, usually in thickness of from 0.25 to 5 mils, preferably about 1 mil. Y
  • the plastics used are impermeable or substantially impermeable tewater and prevent transmission of moisture through to the adhesive bonding detergent and barrier, thus preventing or inhibiting the weakening laction of wash water on such adhesive. Although some wash water may contact the edges of adhesive layer under the barrier, this will not usually sufficiently weaken the bond to causethe separation of barrier fil-m from detergent. It has been found that layers of water insoluble adhesives alone will not perform the function of a thin continuous plastic film, apparently because the adhesives, even though carefully applied, do contain perforations through which water may penetrate to loosen the detergent- ⁇ barrier bond. This Afault is accentuated when thin adhesive layers are used. Although sheet plastics also sometimes contain minute openings, usually these are few enough and small enough so that very thin films are substantially impermeable to Water.

  • Such plastics are considered to be Cellulosic plastics, such as cellulose acetate and acetate-butylate have rather high moisture absorption and transmission rates and are less flexible than the other plastics listed but Vmay be useful in certain applications.
  • the waxy plas- ⁇ tics such as polyethylene and-polypropylene are good barriers, having moisture absorptions of about 0.01% or less but are more difficult to fasten firmly to soap and sponge than the plastics listed above.
  • Other barrier film materials than the plastics e.g., aluminum foil, prevent moisture penetration and can be cemented but they are relatively unyielding in washing, causing some skin irritationduring use, and are easily creased or marked in handling.
  • the water insoluble adhesive employed to hold the bers such as polyisobutylene, polyisoprene, neoprene' GR-S and thiokol can also be used.

  • the detergent is of alkaline reaction, eg., soap
  • the cement should be resistant thereto so that it is not hydrolyzed or otherwise adversely affected in use.
  • Nitrile rubber, epoxy resin and polyisobutylene adhesive on the invented products retain their adhesive, powers, even in strong soap solutions.
  • the sponge and barrier film may be sealed together by othermeans, too.
  • fusion or heat sealing is sometimes applicable.
  • the sponge may have its surface fused or molded to form a continuous film or skin on the surface to be joined to the detergent. Even staples or other holding devices could be used if unobtrusive and unobjectionable in use and if the barrier was resealed or otherwise kept water impermeable.
  • barrier film to sponge While the fastening of barrier film to sponge may be eected by various means and the selection of an adhesive is not extremely critical, the problem of sealing a material to a detergent is more difficult of solution. Itl has been found, after extensive experimentation that many water insoluble adhesives that are capable of adhering to dry soap and other detergent materials are easily removed when the detergent becomes wet or moist. The provision of a barrier between sponge and soap mitigates this adverse effect but it is still highly preferable to employ certain types of adhesives for best adherences. It has been found that the non-resilient 4and inflexible adhesives, such as epoxy resins, phenol and formaldehyde derivatives, proteinaceous gluesv and so forth leave an objectionablehard, sometimes crystal-like deposit on the barrier after the detergent has been consumed.
