US 7594594 B2Abstract
Multi-compartment storage and delivery containers, use of storing and dispensing reactive fluidic compositions, and utilization of such containers for pre-storing in separate compartments and subsequently mixing (i) suspensions of microencapsulated fragrance(s) and/or benefit agent(s) with (ii) fluidic surface or volume treatment agent compositions and then delivering the resulting mixture(s) to at least one solid or semi-solid surface and/or gaseous-phase or liquid-phase defined volumes.
Situations exist where it is desirable to provide to a solid or semi-solid surface or to a liquid phase or vapor phase three-dimensional volume a mixture of two, three or four compositions, one or more components of which chemically react and/or physically interact with another of the components of another of the compositions and whose reaction and/or interaction is desired to occur on the aforementioned solid or semi-solid surface or in the aforementioned liquid phase or vapor phase three-dimensional volume but not in the container wherein the aforementioned two, three or four compositions are stored. Examples of this type of system include:
(f) adhesion systems and/or plumbing systems in which (i) a pre-polymer such as an epoxy resin pre-polymer, e.g. the reaction product of epichlorohydrin and bis-phenol-A or a cross-linkable vinyl polymer such as a low molecular weight polyacrylic acid-polyacrylamide co-polymer, (ii) optionally a cross-linking agent such as a melamine-formaldehyde cross-linker and (iii) a curing catalyst are brought together at the junction of two solid surfaces of two articles in order to permanently adhere the article surfaces, one to the other, for example, using the package instructions for the epoxy resin pre-polymer—curing agent , J-B WELD� Mary L. Bonham and VersaChem� 4 Minute Epoxy Steel Quick Set Type 44™, ITW Performance Polymers Consumer Division.

no specificity as to the ‘product forms’ mentioned is disclosed or suggested in the prior art.
It is, accordingly, an object of our invention to provide reactive and/or interactive composition pre-storage and delivery systems where, immediately prior to use, the rate of mixing of the reactive and/or interactive compositions and time of mixture storage prior to delivery to the surface-to-be-treated or to the liquid phase or gaseous phase three-dimensional volume-to-be treated are readily controllable.
Another object of our invention is to provide a ‘product form’ for enabling storage and delivery of personal care, surface cleaning and fabric care “bases” with microencapsulated fragrance and/or benefit agent, such as an insect repellent, an air freshener and/or a malodour counteractant slurry suspensions.
(a) reactive and/or interactive composition pre-storage and delivery systems where, immediately prior to use, the rate of mixing of the reactive and/or interactive compositions and time of mixture storage prior to delivery to the surface-to-be-treated or to the liquid phase or gaseous phase three-dimensional volume-to-be treated are readily controllable; (b) a ‘product form’ for enabling storage and delivery of personal care, surface cleaning and fabric care “bases” with microencapsulated fragrance and/or benefit agent, slurry suspensions; and (c) a versatile multi (2-4) separated compartment article (initially containing, separately, in each compartment, a fluidic composition which contains at least one component which will chemically react and/or physically interact over a relatively short period of time with at least one component of another fluidic composition located in another of the compartments on mixing therewith) that can, when in either (i) a stationery upright position or (ii) when being held in a non-vertical position is capable of providing in an expeditiously controlled manner a temporarily storable, deliverable and promptly usable mixture of the reactive and/or interactive component-containing pre-stored compositions. More particularly, our invention is directed to a multiple (2-4)-compartment fluidic individually stable, pre-storable composition storage and unstable mixture-forming and delivery container having separate compartments each communicating with a single mixing zone, where reactive and/or interactive fluidic compositions, each of which is individually stable and pre-storable, are mixed, via an externally-located fluidic composition multiple delivery tube system juxtaposed with the outer surfaces of the compartment walls; and (2) a system designed for the utilization of such a multiple (2-4)-compartment stable composition storage, unstable mixture-forming and delivery container for pre-storing in separate compartments and subsequently mixing (i) individually stable, pre-storable suspensions of microencapsulated fragrance(s) and/or benefit agent(s) with (ii) one or more individually stable, pre-storable fluidic surface or volume treatment compositions such as a cleaning agent composition, a personal care composition, an aqueous liquid detergent composition and/or a fabric softening composition and then delivering the resulting unstable mixture(s) to at least one solid or semi-solid surface or a liquid-phase or gaseous-phase defined volume. The system includes (a) a shelf-stable pre-mix comprising two or more components wherein at least one component is an aqueous suspension of microencapsulated fragrance(s) and/or benefit agent(s) and a second component is a fluidic surface or volume treatment composition such as a liquid detergent composition or liquid fabric softener composition; wherein each of the fluidic compositions is stored separately and, as which are stable, but the fluidic compositions are combinable and thus in an unstable state, and wherein are included all ingredients necessary to be applied to a solid or semi-solid surface or a liquid or gaseous defined volume causing the benefits of said fluidic surface or volume treatment composition(s) and said fragrance and/or benefit agent to be imparted to said solid or semi-solid surface or gaseous-phase or liquid-phase defined volume; (b) a method for combining the components of the premix and (c) a specific article for effecting the admixture and subsequent delivery of the pre-mix components.

Extending upwardly from the entirety of the mixing chamber base circumferential edge is a substantially vertically-disposed continuous liquid-impermeable mixing chamber sidewall terminating at its upper end at a mixing chamber upper horizontally-disposed planar lid. The mixing chamber lid has an orifice there through (preferably circular or elliptical in shape) which orifice has a mixing chamber upper inner orifice rim. The mixing chamber sidewall has from two to four spaced mixing chamber fluidic composition entry orifices there through with the number of the mixing chamber fluidic composition entry orifices being equal to the number of hollow upright storage members. Each mixing chamber entry orifice is in communication with each storage member exiting orifice via a communication tube as more fully described, supra. Also, each mixing chamber entry orifice has an inside diameter equal to that of the inside diameter of a corresponding vertically-positioned fluidic composition communication tube fitted thereto, as more fully described, infra; (c) abutting the entirety of the mixing chamber upper orifice rim in a liquid-tight manner, a hollow substantially cylindrical or frusto-conical cap member having a substantially planar horizontally-disposed upper cap base having an upper cap base circumferential edge.

(B) A process for dispensing from the immediately-aforementioned article (A), above an unstable mixture of at least two fluidic compositions, termed “S1”, “S2” “S3” and “S4”, or, more generally, “S1+. . . +Sn” wherein n is an integer of from 2 to 4, which react and/or interact with one-another over a given period of time. Such process comprises the steps of:
(a) providing a dis-assembled article whereby the cap member is removed from the mixing chamber upper inner orifice rim in order to facilitate fluidic composition entry into each 3-space of each of said storage members; (b) at least partially filling each storage member 3-space with a different individually stable, pre-storable fluidic composition; (c) completing assembly of the article whereby the cap member is detachably attached to the mixing chamber upper inner orifice rim; (d) Applying manual pressure to the flexible (or ‘elastically deformable’) sidewall of each of the storage members containing an individually stable, pre-storable fluidic composition, thereby effecting fluid flow from at least two of said storage member 3-spaces into the mixing chamber thereby forming in said mixing chamber an unstable mixture of S1+. . . +Sn; (e) Removing the cap member from the article; (f) transporting the resulting unstable mixture of S1+. . . +Sn into the inner void of the cap member; and (g) dispensing the unstable mixture of S1+. . . +Sn from the cap member;

The microcapsule walls are preferably composed of an aminoplast resin, more specifically a substituted or un-substituted acrylic acid polymer or co-polymer cross-linked with a urea-formaldehyde pre-condensate or a melamine-formaldehyde pre-condensate. The microcapsule is formed by means of either (a) forming an aqueous dispersion of a non-cured aminoplast resin by reacting under acidic pH conditions a urea-formaldehyde pre-condensate or a melamine-formaldehyde pre-condensate with one or more substituted or un-substituted acrylic acid polymers or co-polymers; then coacervating the resulting non-cured aminoplast resin shell about the surface of a fragrance and/or malodour counteractant-solvent monophasic droplet under homogenization and then curing the microcapsule shell wall at an elevated temperature, e.g. 50-85� C. or (b) forming the aminoplast resin wall at the surface of the fragrance and/or malodour counteractant—solvent monophasic droplet by means of reacting, at the surface of the droplet a urea-formaldehyde pre-condensate or a melamine-formaldehyde pre-condensate with one or more substituted or un-substituted acrylic acid polymers or co-polymers, and then curing the microcapsule shell wall at an elevated temperature, e.g. 50-85� C.
The urea-formaldehyde and melamine-formaldehyde pre-condensate microcapsule shell wall precursors are prepared by means of reacting urea or melamine with formaldehyde where the mole ratio of melamine or urea to formaldehyde is in the range of from about 10:1 to about 1:6, preferably from about 1:2 to about 1:5. For purposes of practicing our invention, the resulting material has a molecular weight in the range of from 156 to 3000. The resulting material may be used ‘as-is’ as a cross-linking agent for the aforementioned substituted or un-substituted acrylic acid polymer or copolymer or it may be further reacted with a C1-C6 alkanol, e.g. methanol, ethanol, 2-propanol, 3-propanol, 1-butanol, 1-pentanol or 1-hexanol, thereby forming a partial ether where the mole ratio of melamine or urea:formalhyde:alkanol is in the range of 1:(0.1-6):(0.1-6). The resulting ether moiety-containing product may by used ‘as-is’ as a cross-linking agent for the aforementioned substituted or un-substituted acrylic acid polymer or copolymer, or it may be self-condensed to form dimmers, trimmers and/or tetramers which may also be used as cross-linking agents for the aforementioned substituted or un-substituted acrylic acid polymers or co-polymers. Methods for formation of such melamine-formaldehyde and urea-formaldehyde pre-condensates are set forth in U.S. Pat. No. 3,516,846, 6,261,483, and Lee et al. J. Microencapsulation, 2002, Vol. 19, No. 5, pp 559-569, “Microencapsulation of fragrant oil via in situ polymerization: effects of pH and melamine-formaldehyde molar ratio”. Examples of urea-formaldehyde pre-condensates useful in the practice of our invention are URAC 180 and URAC 186, Cytec Technology Corp. Examples of melamine-formaldehyde pre-condensates useful in the practice of our invention are CYMEL U-60, CYMEL U-64 and CYMEL U-65, Cytec Technology Corp. In the practice of our invention it is preferable to use as the precondensate for cross-linking the substituted or un-substituted acrylic acid polymer or co-polymer the melamine-formaldehyde pre-condensate having the structure:
The content of the resulting microcapsule includes a fragrance composition and/or a benefit agent such as a malodour counteractant composition in combination with a compatible hydrophobic solvent. The term “compatible” is herein intended to mean chemically non-reactive with every fragrance component and/or benefit agent such as a malodour counteractant component and capable of forming a single liquid phase with each fragrance composition component and with each benefit agent component such as a malodour counteractant composition component. In the practice of our invention, the range of weight percent of solvent/fragrance composition components and/or solvent/malodour counteractant composition components contained in each of the microcapsules is from about 50% to about 97% by weight of the microcapsule, preferably from about 91% to about 96%. Thus, the range of weight ratios of encapsulating polymer to solvent/fragrance composition components and/or solvent/malodour counteractant components is from about 1:25 to about 1:1; preferably from about 1:10 to about 4:96. In addition, the range of weight percent of solvent in the microcapsule is from about 10% to 80% by weight of the filled microcapsule. The preferred ratio of weight of solvent: weight of encapsulated fragrance composition and/or encapsulated malodour counteractant composition is from about 2:1 to about 1:2, with the most preferred ratio being 1:1.
The values of log10P have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc., Daylight CIS, Irvine, Calif. However, the log10P values are most conveniently calculated by the “CLOGP” program, also available from Daylight CIS. This program also lists experimental log10P values when they are available in the Pomona92 database. The “calculated log10P” (C log10P) is determined by the Hansch and Leo “fragment” approach based on the chemical structure of each functional product ingredient, and takes into account the numbers and types of atoms, the atom connectivity and the chemical bonding. The C log10P values which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental log10P values for the selection of functional ingredients, including perfume ingredients which are useful components in the microencapsulate-containing slurries useful in the practice of our invention.
In such case, each of the rupturable microcapsules is a permeable microcapsule containing at least 20 weight percent of a ‘sacrificial’ solvent capable of migrating outside of the capsule over a period of time ranging from about 50 hours to about 200 hours. Preferable ‘sacrificial’ solvents are benzyl acetate and n-octanol or mixtures thereof, e.g. a 40:60 weight weight mixture of benzyl acetate and n-octanol.
The non-confined fragrance and/or benefit agent composition in the stable suspension useful in the practice of our invention is contained in the “oil-in-water” emulsion droplets which are part of the emulsion in which the microencapsulated fragrance and/or benefit agent is suspended. The C log10P range of each of the non-confined fragrance and/or benefit agent components is in the range of from about 1 to about 8 thus enabling a greater range of fragrance and/or benefit agent component types in the non-confined fragrance and/or benefit agent as opposed to the components of the confined or microencapsulated fragrance and/or benefit agent.
For example, members of the following group of isotropic liquids disclosed in U.S. Pat. No. 5,723,434 are particularly useful as stable, pre-storable fluidic surface treatment compositions for admixing with a stable microencapsulated fragrance and/or benefit agent slurry suspension whereby an ‘unstable’ surface treatment composition for delivery to, for example, a washing machine simultaneously with the delivery to the washing machine of a fabric to be treated:
When practicing our invention using, for example, a member of the group of isotropic liquids disclosed in U.S. Pat. No. 5,723,434 as a re-storable, individually stable surface treatment composition with a stable microencapsulated fragrance and/or benefit agent slurry suspension whereby an ‘unstable’ surface treatment composition for delivery to, for example, a washing machine simultaneously with the delivery to the washing machine of a fabric to be treated, the following algorithms have been determined:
( v - F ) ( T 273 ) = A ⅇ - K θ - BLN ( θ + C ) + D wherein T is mixture temperature in degrees Kelvin and wherein

Thus, each of the internal storage 3-spaces (or ‘three-dimensional volumes’) is bounded by (i) a planar storage member base, (ii) a storage member sidewall and (iii) a planar storage member lid; (b) Atop a section of each of the storage member lids and covering a substantial surface area thereof is an upright hollow mixing chamber 14 having a horizontally-disposed planar mixing chamber base juxtaposed in its entirety with each of the planar storage member lids and having a mixing chamber circumferential edge. Extending upwardly from the entirety of the mixing chamber base circumferential edge is a substantially vertically-disposed continuous liquid-impermeable mixing chamber sidewall terminating at its upper end at a mixing chamber upper horizontally-disposed planar lid having an orifice there through, said orifice having a mixing chamber upper inner orifice rim. The mixing chamber sidewall has three spaced mixing chamber fluidic composition entry orifices there through; (c) Abutting the entirety of the mixing chamber upper orifice rim in a liquid-tight manner is a hollow substantially frusto-conical cap member 16 having a substantially planar horizontally-disposed upper cap base 17 having an upper cap base circumferential edge. Air vent 1B, described in detail in the detailed description of FIGS. 1B, 1B′ and 27F, supra, is shown to be contained in the upper cap base. Extending downwardly from the upper cap base circumferential edge, a substantially continuous substantially vertically-disposed cap sidewall terminating at and abutting the upper circumferential rim of the mixing chamber; and (d) Three vertically disposed storage member-mixing chamber fluidic composition elastically deformable communication tubes 12K, 12L and 12M each of which tube extends within the aforementioned vertical wall depression 40K, 40L and 40M in a substantially vertical direction from and connects with the corresponding fluidic composition exiting orifice of a storage member 6K, 6L and 6M, respectively, to one fluidic composition entry orifice of the mixing member adjacent to and abutting the outer side of the corresponding storage member sidewall. Optionally, each lid has a corresponding depression for each fluidic composition communication tube leading to the corresponding mixing chamber entry orifice (as shown in FIG. 9; but not in FIG. 10 or FIG. 11). Each communication tube 12K, 12L and 12M is shown to contain a one-way check valve, 1A, described in detail in the detailed description of FIG. 1A, supra.
The process of our invention can also be carried out using the ‘pump-type’ dual compartment articles illustrated in FIGS. 14A and 14B. The dual compartment articles of FIGS. 14A and 14B each has a compound entry and egress opening permitting filling of the container compartments separately and permitting egress of compositions from the compartments. In employing the article of FIG. 14A in the process of our invention, into compartment 76A is placed (i) microencapsulated fragrance and/or benefit agent slurry suspension and into compartment 76B is placed (ii) a liquid fabric care composition, e.g. the liquid detergent, WISK� and/or the fabric softener SUAVITEL�. The pump/delivery assembly is then attached to the compound entry and egress opening. When pump handle 70 is engaged (that is downward pressure is applied thereto at 70) positive pressure through tubes 78A and 78B causes the microencapsulated fragrance and/or benefit agent slurry suspension to be transported through tube 80A and simultaneously causes the liquid fabric care composition, e.g. the liquid detergent, WISK� and/or the fabric softener SUAVITEL� to be transported through tube 80B with both compositions then mixing in mixing zone 71 and delivered through aperture 72 to, for example, a washing machine together with a fabric article to be treated. In employing the article of FIG. 14B, into compartment 94B having wall 96B is placed (i) microencapsulated fragrance and/or benefit agent slurry suspension and into compartment 94A having base 96A is placed (ii) a liquid fabric care composition, e.g. the liquid detergent, WISK� and/or the fabric softener SUAVITEL�. The pump/delivery assembly is then attached to the compound entry and egress opening. When pump handle 70/90 is engaged (that is downward hydraulic pressure is applied thereto at 70) positive pressure through tubes 91, 93A and 93B causes the microencapsulated fragrance and/or benefit agent slurry suspension to be transported through tube 95B and simultaneously causes the liquid fabric care composition, e.g. the liquid detergent, WISK� and/or the fabric softener SUAVITEL� to be transported through tube 95A with both compositions then flowing past location 98 and mixing in mixing zone 108 and delivered through aperture 109 to, for example, a washing machine together with a fabric article to be treated.
