20070192981
The present invention relates to a device for delivering stain removing compositions based upon the nature of a particular stain. More particularly, the device comprises an all-in-one dispenser housing multiple stain removal compositions selected for treatment of various encountered types of stains.
Stain removers have long been used in the context of laundry care. Generally, stain remover compositions are applied as pre-wash treatments to facilitate removal of a stain during subsequent laundering. The stain removers are typically dispensed onto the soiled area and allowed to soak in to “loosen” the components of the stain. Various embodiments exist to facilitate application of a stain removing composition, and, generally, the stain removing composition comprises a liquid, solid, or semi-solid form applied directly to the stain. Regardless of the application, the composition is generally selected to facilitate removal of a variety of stains one might encounter during general laundering. For example, a stain removing composition is generally not specifically selected to remove particular stains (e.g., grass, blood, ink, dirt, food and the like) but, rather, selected to facilitate general removal of a variety of types of stains.
What is needed is a selection of discrete stain removal compositions that can be associated together yet individually dispensed to facilitate removal of particular types of stains one may encounter during laundering. Furthermore, to facilitate use of a variety of such compositions, a dispenser is needed to contain the various compositions and allow for easy application and storage.
As set forth in the detailed description and accompanying figures, the present invention includes, in various exemplary embodiments, a dispenser configured to facilitate using a variety of stain removing compositions and that also has the ability to contain the various compositions, further configured for easy application and storage.
In accordance with an exemplary embodiment of the present invention, a dispenser to contain a variety of stain removing compositions is configured in a “wand” configuration wherein the wand comprises at least two linearly nested reservoirs containing the individual compositions. The reservoirs are mutually and interchangeably attachable end to end to form a wand with the selected composition at the wand tip.
In accordance with another exemplary embodiment of the invention, the wand comprises a variety of stain removing compositions within separate reservoirs or divided compartments of the wand, one variety for each reservoir. The tip of the wand, suitably configured to act as the applicator, has the ability to rotate so as to align a dispenser opening or applicator with the desired reservoir to dispense the particular stain removing composition housed within that reservoir.
In accordance with yet another exemplary embodiment of the present invention, a multi-position dispenser having a variety of stain removing compositions therein is configured with at least two reservoirs arranged such that selection between compositions is effected by selective orientation of the dispenser. For example, the dispenser may include multiple ends, sides, facets, or arc segments variously associated with discrete compositions and/or applicators.
Additional embodiments of the invention will become evident upon reviewing the non-limiting embodiments described in the specification and the claims, in conjunction with the accompanying figures, wherein;
The detailed description of various exemplary embodiments of the invention herein makes reference to the accompanying figures. While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it should be understood that other embodiments may be realized and that logical and mechanical changes may be made without departing from the spirit and scope of the invention. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation.
In accordance with an exemplary embodiment of the present invention, a dispenser is configured to house various discrete stain-removing compositions in separate reservoirs. “Stain remover” as used herein, generally may be construed to mean any stain treatment or pre-wash treatment composition for use in washing stained articles such as clothing, carpets, or other launderable fabrics or textiles. Thus, a stain remover may be used alone or in combination with a second stain remover composition to remove of a stain from fabrics before or during laundering.
A “dispenser” is any device including a composition reservoir or associate reservoirs and optionally an applicator suitably configured to dispense the various stain-removing compositions. A “reservoir” is any compartment suitable to contain a composition in any form. Suitable reservoirs include rigid or squeezable bottles, sticks, or segments of a larger container, and the like. An “applicator” may be associated with the reservoir to better control treatment of a stained article with a composition. Exemplary applicators include a pour spout, roll-on applicator, sponge applicator, stick, dispenser opening, pump and pressure release valve.
Thus, any number of stain remover compositions may be contained in any number of reservoirs associated together in a dispenser. A common applicator may be associated with the dispenser for use with a selected reservoir. Alternatively, individual applicators may be associated with particular reservoirs. Stain removal compositions may be selected for use in a multi-stage treatment. Reservoirs may be color coordinated to indicate the type of stain for which a composition is to be used.
In accordance with an exemplary embodiment of the present invention, a dispenser is configured in a “wand” configuration with at least two stain-removing compositions contained within at least two linearly nested modules. The nested modules allow the user to maintain the various stain-removing compositions in a single location.

In accordance with an alternative exemplary embodiment of the present invention, the dispenser comprises a positional embodiment, wherein the dispenser is configured to have at least two reservoirs to house the various stain removing compositions. Suitably connected to each reservoir is a stain removing applicator tailored to dispense the composition. Selection of a composition depends on position of the dispenser, for example, through orientation of one of multiple ends, sides, facets, or arc segments of the dispenser relative to the stained article.
As illustrated in
Again, one skilled in the art should appreciate that various reservoir and applicator configurations discussed herein, earlier, may also apply to this exemplary embodiment. It will also be appreciated by those skilled in the art that the various reservoirs described herein may comprise a transparent or semi-transparent configuration, such that a user may determine to what level, a particular amount of composition remains. Alternatively, the reservoirs may be color coordinated according to the type of stain to be treated.
As described herein, the present invention is directed towards a dispenser that may accommodate a variety of stain-removing compositions tailored to combating a particular stain. Thus, in accordance with various exemplary embodiments of the present invention, various stain removing compositions comprise, in various combinations and amounts, a composition for pre-treating and removing stains and/or soils on fabric articles and other launderable textiles before laundering, comprising: (i) a cleaning component; (ii) optionally, water; (iii) optionally, at least one enzyme; and (iv) optionally, at least one anti-redeposition agent.
In accordance with a further exemplary embodiment of the present invention, a cleaning composition for facilitating at least partial removal of a stain from a fabric article is provided, which comprises: (i) a cleaning component; (ii) at least one solvent; (iii) optionally, at least one anti-redeposition agent; (iv) optionally, at least one liquid carrier; and (v) optionally, at least one enzyme.
In yet a further embodiment of the present invention, a stain remover for facilitating at least partial removal of a stain from a fabric comprises: (i) a nonionic surfactant blend; and (ii) at least one solvent.
A stain remover in accordance with various exemplary embodiments of the present invention generally comprises at least a cleaning component element. In an exemplary embodiment of the invention, the cleaning component includes a blend of nonionic surfactants. Suitable nonionic surfactants for use in the nonionic surfactant blend in accordance with one aspect of the present invention include linear primary alcohol ethoxylates. In an exemplary embodiment of the invention, the nonionic surfactant blend of the stain remover may comprise a linear primary alcohol ethoxylate such as L48-3, such as is available as Surfonic 48-3 as manufactured by Huntsman, having an alkyl chain length of C14 to C18 and 3 moles of ethylene oxide.
In accordance with another exemplary embodiment, the nonionic surfactant blend may include a linear primary alcohol ethoxylate such as L24-12, such as is available as Surfonic 24-12, as manufactured by Huntsman, having an alkyl chain length of C12 to C14 and 12 moles of ethylene oxide. A wide variety of LPAE's are manufactured for use in cleaning products, and any now know or hereafter devised LPAE suitable for use in the compositions of the present invention may be used. Preferably, the water soluble EO-hydrophile ranges from about 3 to about 15 EO units, and the alkyl portion comprises on the order of about 6 to about 22 carbons. Other suitable LPAE's may include Surfonic L12-3 to L12-15 and L46-3 to L46-20 (Huntsman), Tomadol 1-3 to 1-9 and Tomadol 25-3 to 25-9 (Tomah), and Biodac 39 to 89 (Sasol/Condea)
In accordance with yet another exemplary embodiment of the invention, the nonionic surfactant blend may include a mixture of linear primary alcohol ethoxylates having a range of alkyl chain lengths with a range of moles of ethylene oxide. For example, a suitable nonionic surfactant blend for use in the present invention may include a mixture of L48-3 and L24-12 linear primary alcohol ethoxylates. Nonionic surfactant blends comprising primary alcohols having varying alkyl chain lengths and varying numbers of moles of ethylene oxide groups may increase the efficiency of cleaning while also stabilizing the composition.
The nonionic surfactant blend, in still yet another exemplary embodiment, may also comprise iso-branched primary alcohol ethoxylates. In one exemplary embodiment of the invention, a suitable iso-branched primary alcohol ethoxylate may include TDA-3, such as is available as Surfonic TDA-3, as manufactured by Huntsman. The surfactants based upon Iso-branched alcohols are likewise ethoxylated as the linear alcohols above. Among the ethoxylated alcohols, the low wt % TDA-3 combines a strong hydrophobe for efficient cleaning and a low degree of ethoxylation for fluid structure. Iso-branched primary alcohol ethoxylates can be effective cleaners for stains such as dirty motor oil stains, greasy stains, which are susceptible to the fluidity of the branched alkyl chains. Further, while not wishing to be bound by any particular theory, it is believed that branched chain lengths disrupt the “packing” of the surfactant into liquid and solid crystals, thus improving stability of the composition. In addition, branched chain lengths tend to be fluid at lower temperatures as compared to linear chain lengths, thus providing cleaning over a broader range of temperatures.
In accordance with various exemplary embodiments of the invention, the cleaning component may comprise any surfactant or surfactant blend that provides a cleaning benefit to the stain remover. For example, it will be appreciated that any suitable anionic, nonionic, ampholytic, zwitterionic, cationic or other surfactant or surfactant mixture may be used. Preferably, the surfactant or surfactant blend is formulated so as to exhibit a cleaning benefit for a variety of stains such as oily stains, waxy stains, sebum stains, protein stains, starchy stains, food stains, and particulate stains.
In accordance with a further aspect of an exemplary embodiment of the invention, the stain remover may comprise at least one solvent. One example of a class of solvents suitable for use in the stain remover according to various embodiments of the present invention is glycol ethers, such as Dowanal® DB glycol ether manufactured by Dow Chemical Company. Moreover, in addition to acting as a solvent, Dowanal® DB facilitates thickening of the foam of the stain remover. Another example of a solvent suitable for use in the stain remover of the present invention includes propylene glycol. A wide variety of glycol ethers are available commercially for use in cleaning products.
In accordance with another embodiment of the present invention, the solvent may comprise any suitable solvent that provides a cleansing benefit for oily, waxy, particulate or sebum stains. The solvent may comprise a low volatility and may be formed of any suitable glycolic, alcoholic or esteric, etheric hydrocarbon.
In accordance with various exemplary embodiments, the stain remover may comprise one or more enzymes that provide additional cleaning performance and/or fabric care benefits. A preferred enzyme suitable for use in the stain remover of the present invention includes the protease enzyme, such as that sold under the trademark Savinase® by Novo-Nordisk A/S. Protease provides an effective cleaning benefit for protein-based stains, such as, for example, blood and grass. Another enzyme suitable for use in the stain remover of the present invention is the amylase enzyme, such as that sold under the trademark Duramyl® by Novo-Nordisk A/S. The amylase enzyme may be included to facilitate removal of carbohydrate-based stains, such as those caused by puddings, cooked cereals, starchy foods and the like. Starchy stains can be problematic as they can be invisible until particulates absorb onto them. Other enzymes suitable for use in the stain remover of the present invention include those selected from cellulases, hemicellulases, peroxidases, gluco-amylases, lipases, cutinases, pectinases, xylanases, reductases, oxidases, phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, malanases, glucanases, arabinosidases or mixtures thereof.
A stain remover in accordance with the present invention may also include, in accordance with an exemplary embodiment, a liquid carrier. Typically, the liquid carrier comprises water, as water is a readily available and a relatively inexpensive liquid carrier. In addition, water may facilitate the cleaning of water-soluble stains. However, other suitable liquid carriers may include Propylene glycol, glycerin or other aforementioned glycol ethers or blends thereof.
A stain remover in accordance with various embodiments of the present invention may also contain other optional ingredients. For example, the stain remover may include one or more anti-redeposition agents, such as, maleic acid/acrylic acid polymers, such as, for example, Acusol® 505, 602 445, available from Rohm and Haas Company. Other anti-redeposition agents include Acusol® 460, or other now known or hereafter devised anti-redeposition agents.
The stain remover also may include one or more preservatives, such as, for example, Dowicil® 75 manufactured by Dow Chemical Company. Moreover, the stain remover may include one or more enzyme stabilizers that stabilize the enzymes in the stain remover. Examples of enzyme stabilizers suitable for use in accordance with various embodiments of the stain remover of the present invention include Na2B4O.10H2O, which facilitates stabilization of the protease enzyme, and CaCl2.2H2O, which facilitates stabilization of the amylase enzyme. The stain remover may also include fragrances, dyes, pH adjusting agents, antibacterial agents, and the like.
Finally, various principles of the invention have been described in illustrative embodiments. However, many combinations and modifications of the above-described structures, arrangements, proportions, elements, materials and components, used in the practice of the invention, in addition to those not specifically described, can be varied without departing from those principles.
