Description
A UNIT-DOSE DISPENSER
TECHNICAL FIELD
The present invention relates to a dispenser for detergent unit-doses comprising : a) a storage compartment containing at least one detergent unit-dose; b) a dispensing means for dispensing said detergent unit-dose; and c) a fragrance delivery component. The dispenser herein provides excellent fragrance delivery performance.
BACKGROUND
Detergent unit-doses represent a convenient way of delivering detergent products to an end-user.
Indeed, such detergent unit-doses, including tablets and water-soluble capsules comprising solid and/or liquid compositions, can be directly used by an end-user without the inconvenience for the end-user to determine the adequate dosage in grams or milliliters of the detergent. The manufacturer of such detergent unit-doses provide simplified usage instructions, instructing an end-user to dose one, two or a multitude of such detergent unit-doses.
Therefore, detergent unit-doses are the preferred detergent forms by a large number of end-users.
Detergent unit-doses may be used in the field of hard surface cleaning, for example for all purpose cleaners, floor cleaners and lavatory bowl cleaners.
Containers for such detergent unit-doses are well known in the art. Indeed, tablets are frequently packed in carton boxes or plastic tubs. Water-soluble capsules comprising solid and/or liquid compositions may be packed in plastic tubs or pouches. WO 03/047998 describes a plastic pouch for water-soluble capsules.
A known drawback with the currently known containers for such detergent unit-doses, such as carton boxes, plastic tubs, pouches, etc., is their inconvenience for the end-user in dispensing the detergent unit-dose. Indeed, the end-user attempting to use a detergent unit-dose has to open the container and finger one or more of said portions out of the container.

Containers for such detergent unit-doses are well known in the art. Indeed, tablets are frequently packed in carton boxes or plastic tubs. Water-soluble capsules comprising solid and/or liquid compositions may be packed in plastic tubs or pouches. WO 03/047998 describes a plastic pouch for water-soluble capsules.
A known drawback with the currently known containers for such detergent unit-doses, such as carton boxes, plastic tubs, pouches, etc., is their inconvenience for the end-user in dispensing the detergent unit-dose. Indeed, the end-user attempting to use a detergent unit-dose has to open the container and finger one or more of said portions out of the container.
2 In addition to the convenience drawback associated with current unit-dose containers upon dispensing of the detergent unit-doses, it is desirable that such containers provide fragrance (i.e., perfume and/or deodorant) delivery into the atmosphere or ambiance air of the room wherein such containers are stored and/or used. Indeed, such rooms, including lavatories, bathrooms, kitchens, basements, garages, broom closets and the like, are prone to developing an undesirable or bad smell due to the activities performed therein and/or the soiled hard surfaces found therein and/or other items stored therein. This applies in particular to bathrooms and/or lavatories due to the presence of toilets and urinals in such rooms.
In view of the above, it is therefore an objective of the present invention to provide a container for detergent unit-doses that provides a combination of ongoing fragrance (i.e., perfume and/or deodorant) delivery into atmosphere (ambient air of the room wherein said dispenser is used /
stored) with a convenient way of dispensing the detergent unit-doses.
It has now been found that the above objective can be met by the dispenser for detergent unit-doses according to the present invention, wherein a fragrance (i.e., perfume and/or deodorant) is dispended continuously into the ambient air and wherein said container provides a convenient means of dispensing the detergent unit-doses.
Advantageously, the dispenser according to the present invention also improves the handling of detergent-unit doses by the end user. Indeed, usually detergent-unit doses are individually packed in a flow-wrap to protect them from moisture or degradation (in particular in case of tablets).
Opening such flow-wraps is often a messy operation, which requires the end user to touch the product. For the dispensers herein, no individual package is needed for each detergent unit-dose, which simplifies the dispensing by the end user of the detergent unit-dose by the end user.
Furthermore, due to the use of a dispenser herein, there is no need for the end user to touch the detergent unit-dose whereby direct contact is prevented, which has a beneficial effect on the stability of the detergent unit-dose and the potential for skin irritation caused by the detergent unit-dose is reduced.

The fragrance delivery component herein may be attached to the outside portion of the dispenser or may form part of the interior portion of the dispenser or may be in a separate compartment (if any of the dispenser).
Alternatively, the fragrance delivery component may be combined with the storage compartment herein. Indeed, said fragrance delivery component may be located in a separate compartment that forms part of the storage compartment. In this case, a refill of the storage compartment as a whole (as described herein) would also include a refill of the fragrance delivery component, which provides a user-friendly and economical way of refilling the dispenser herein.
In the preferred embodiment, wherein the fragrance delivery component herein forms part of the interior portion of the dispenser according to the present invention, the dispenser may contain a means of communication for air flow between the fragrance delivery component and the ambiance. Indeed, the dispenser and/or the outer casing, if any, may contain openings, holes, cut-outs or apertures permitting air flow between the fragrance delivery component and the ambiance.
Additionally, the fragrance delivery component may also be present in a separate compartment of said dispenser, having a means of communication for air flow with the ambiance. Indeed, the dispenser and/or the outer casing, if any, may contain openings, holes, cut-outs or apertures permitting air flow between the fragrance delivery component and the ambiance.
In a highly preferred embodiment herein, the fragrance delivery component is in communication with the exterior of the dispenser herein / the ambiance, allowing for air flow there between.
Any fragrance delivery component suitable of delivering a fragrance into the ambiance over a prolonged period of time may be used in the dispenser herein. Suitable fragrance delivery components are selected from the group consisting of : fragranced gels;
fragranced plastics; a wick delivery system comprising a fragrance-containing liquid; permeable film delivery systems combined with a fragranced gel or a fragrance-containing liquid; and battery powered / electrical fragrance release systems or gravity driven fragrance release cartridges; and combinations thereof. The fragrance delivery component can be incorporated into the dispenser of the present invention in a variety of different ways. Suitable non-limiting examples are shown herein below :
Frauanced wl In a preferred embodiment of the present invention, the fragrance delivery component herein may be a fragranced gel that preferably continuously releases a fragrance for a prolonged period of time. More preferably, the fragrance delivery component herein is a perfumed gel.
By "fragranced/perfumed gel" it is meant herein any wax- and/or gel-based substance that contains a fragrance/perfume and is capable of releasing the fragrance/perfume into the atmosphere.
Fragranced gels include any type of wax- and/or gel-based substances suitable to release a fragrance. More preferably, the fragranced gel herein is an anhydrous or an aqueous fragranced gel.
Preferably, the wax- and/or gel-based substances for use herein are selected from the group consisting of : anhydrous wax- and/or gel-based substances; and aqueous wax-and/or gel-based substances; and mixtures thereof.
Preferred anhydrous wax- and/or gel-based substances for use herein are selected from the group selected from the group consisting of : polyamide polymers; waxes; styrene polymers; stearates;
ester-terminated dimmer acid-based polyamides; maleinized polybutadienes in combination with dihydroxypolybutadienes and an ethoxylated primary amine; maleinized polyisoprenes in combination with dihydroxypolybutadienes and an ethoxylated primary amine; and mixtures thereof.
Preferred aqueous wax- and/or gel-based substances for use herein are selected from the group consisting of : water and a gelling agent such as carrageenan gum or gellan gum; water in combination with polyvinyl alcohol or polyvinyl acetate and dimethyl sulfoxide; water in combination with a polymer such as a polyacrylamide; water in combination with stearic acid, propylene glycol and activated carbon; and anhydrous sodium polyacrylate and mixtures thereof.
These wax- and/or gel-based substances for use herein are typically manufactured by processing them initially in their liquid form, often by heating. Indeed, the gels are typically heated to melt the gel, or the gel is polymerized or gellified in the liquid state at high temperature. A fragrance, preferably a perfume, is subsequently added to the heated gel, and the heated, fragranced liquid is then being cooled to form the gel structure.
In a preferred embodiment herein, the fragranced gel herein is an anhydrous fragranced gel, more preferably the fragranced gel herein is selected from the group consisting of : polyamide polymers additionally containing up to 90% by weight of the fragranced gel of fragrance; waxes additionally containing up to 90% by weight of the fragranced gel of fragrance; styrene polymers additionally containing up to 90% by weight of the fragranced gel of fragrance; stearates additionally containing up to 90% by weight of the fragranced gel of fragrance; ester-terminated dimmer acid-based polyamides additionally containing up to 50% by weight of the fragranced gel of fragrance; maleinized polybutadienes in combination with dihydroxypolybutadienes and an ethoxylated primary amine additionally containing up to 95% by weight of the fragranced gel of fragrance; and maleinized polyisoprenes in combination with dihydroxypolybutadienes and an ethoxylated primary amine additionally containing up to 95% by weight of the fragranced gel of fragrance; and mixtures thereof. Suitable fragranced gels are for example described WO
02/066084, WO 98/17243, US 5,780,527, and WO 01/78794. Suitable perfumed gels are commercially available under the trade name of Crystal Air by Reckitt Benckiser or under the names Sylvaclear , Sylvacote or Uniclear resins, by Arizona Chemical.
Similar performing gels to those listed above may also be used. Anhydrous sodium polyacrylate or similar gel compositions are detailed in US 2002/0041860 Al.
In a highly preferred embodiment of the present invention, the fragranced gel herein is a polymeric composition obtained by combining a low melting point polyamide polymer with a polar thermoplastic elastomer and a fragrance. Such polymeric compositions are described for example in US-Al-2006/0099168.
The term "low melting point polyamide polymers" includes all polyamides having a melting point below 130 C, preferably below 110 C, more preferably below 100 C.
Typically and preferably, the low melting point polyamides for use in the present invention are solid at room temperature. Preferred polyamides are terminated polyamides, particularly preferred are ester terminated polyamides. Examples of these low melting point polyamides include those marketed by Arizona chemicals under the trade name of SYLVACLEAR .
The term "polar thermoplastic elastomer" includes multiphase polymers that comprise "hard" and "soft" phases chemically bonded together in the polymer chain. The "hard"
phase is solid at room temperature and flows upon heating. Examples include blocks of amide, ester and urethane groups. The "soft" phase is rubbery at room temperature. Examples include polyether blocks such 5 as poly(ethylene glycol), poly(propylene glycol) or poly(tetramethylene glycol). At room temperature, the presence of the "hard" phases in the polymer imparts strength and good mechanical properties. When the polymer is heated, these phases become liquid and the polymer melts, allowing for processing in the molten state. Upon re-cooling to room temperature, the phases solidify and the good mechanical properties are regained. A
comprehensive definition of
10 thermoplastic elastomers can be found in Vol 9 of the Kirk-Othmer Encyclopedia of Chemical Technology (4th Edition - Wiley- Interscience, 1996) - under the voice "Elastomers", sub-voice "Thermoplastic Elastomers". Among these polymers those which are suitable for the present invention are those comprising at least one polar monomer. Polar monomers are those monomers which comprise at least a C-X linkage in the molecule wherein said C-X linkage is a polar 15 linkage. Preferably X is an N, S, F, Cl or 0 atom. More preferably said polar linkage is part of a carbonyl group and, more preferably, of an ester group. Preferred polar monomers for the present invention are vinyl acetate, vinyl alcohol, methyl acrylate, ethyl acrylate, butyl acrylate, acrylic acid and salts formed therefrom, methacrylic acid and salts formed therefrom, maleic anhydride, glycidyl methacrylate and carbon monoxide. More preferably the hard phases preferably comprise blocks of amide, ester or urethane groups and the soft phases preferably comprise polyether blocks. Examples of these polar thermoplastic elastomers include thermoplastic polyurethanes, such as those produced under the trade names ESTANE by Noveon, and PELLETHANE
by Dow Chemicals; thermoplastic polyesters, also known as polyether ester copolymers, such as those produced under the trade names HYTREL by DuPont and ARNITEL by DSM, and thermoplastic polyamides, also known as polyether amide copolymers, such as those produced under the trade name PEBAX by Atofina.
In the highly preferred embodiment of the present invention, the fragranced plastic herein is a polymeric composition obtained by combining a low melting point polyamide polymer with a polar thermoplastic elastomer as described above, the fragrance is a perfume composition obtained by combining an ester terminated polyamide, a thermoplastic polyether amide copolymer and a perfume, according to the method described in US-A1-2006/0099168.
In the preferred embodiment herein, wherein the fragrance delivery component herein is a fragranced gel, the fragranced gel, preferably initially, comprises up to 95%, preferably from 10%
to 95%, more preferably from 50% to 95% by weight of fragrance, preferably perfume.
The shape of the gel may be any design suitable to deliver a fragrance into the ambiance. The fragranced gel may be placed directly into any appropriate position or portion on the dispenser.
This includes combining the fragranced gel with the dispenser and/or the outside portion of the storage compartment and/or with its outer casing, if any. For combining the fragranced gel with the dispenser and/or the outside portion of the storage compartment and/or with its outer casing, if any, a recess may be created on the outer surface of the dispenser and/or the outside portion of the storage compartment and/or with the outer casing, if any, to create a region that may be filled with fragranced gel. This recess can easily be created during the dispenser forming process (e.g., via extrusion blow molding, extrusion stretch blow molding, injection molding, thermoforming or vacuum forming process). The recess may be molded into the outer surfaces of the dispenser or its outer casing, if any (on its front panel, top panel, sides, bottom or back panel, if any). This recess is filled with liquid fragranced gel, which is solidified into the recess. Alternatively a recess could be created on the outer surface of the storage compartment. For pieces, which are typically injection molded, blow molded, thermoformed or vacuum formed, a recess can easily be created within the surface of the piece during the molding process itself.
Alternatively, the fragranced gel may be cast as a separate strip and attached into a recesses on the surface of the dispenser and/or its outer casing (if any), via a variety of different means, such as adhesives. Alternatively, the gel may be attached directly to the surface of dispenser and/or its outer casing (if any) without a recess using the same attachment means mentioned above or the dispenser and/or its outer casing (if any) or parts thereof may be fully or partially coated with the fragranced gel by either dipping or spraying the fragranced gel on the surface of the dispenser and/or its outer casing (if any). Alternatively, the fragranced gel may be filled into a separate piece containing a complementary recess to that placed in the surface of the dispenser and/or outer casing (if any), or the fragranced gel may be cast as a separate sheet or strip and attached to such a separate piece. This separate piece is then fastened onto the outer surface of dispenser and/or its outer casing (if any), by clipping the piece into a recess in the outer surface of dispenser and/or its outer casing (if any) or by adhesives or various other means. This separate piece containing the fragranced gel may be sold separately or in combination with the dispenser. The separate piece would therefore be refilled in the dispenser either separately or at the same time as when the storage compartment is refilled with detergent unit-doses.
In a highly preferred embodiment herein, said fragrance delivery component is a fragranced gel, preferably a perfumed gel, which is preferably present in a recess on the outside portion of the dispenser and/or its outer casing (if any).
In the preferred embodiments, wherein the fragranced gel is present in a recess of the dispenser and/or its outer casing (if any) herein, setting the fragranced gel into the recess may be achieved by pouring the heated fragranced gel directly into the recess and allowing it to cool. A small peel-able and preferably transparent film with a high barrier may be placed over the fragranced gel in the recess and sealed to the outer part of the recess in the dispenser and/or its outer casing (if any). This embodiment has the advantage that it protects the fragranced gel prior to use. Indeed, the fragranced gel is replaced at the same time as when the dispenser is replaced, and the peel-able film is removed to expose the gel upon first use.
In addition, two or more layers of gel may be filled on top of each other.
This has the advantage of the lower layer acting as an adhesive to the upper layers. This can more effectively stick the fragranced gel into the dispenser and/or its outer casing (if any) so that is does not drop out due to mechanical agitation, or to prevent undue shrinkage of the gel as the fragrance evaporates. In addition, the level (%) of fragrance can be altered in these layers to better control the release of fragrance from the gel. Alternatively, two or more different gels can be cast into the dispenser herein (or its outer casing, if any) side by side. This has the advantage of creating better aesthetics for the consumer. In addition, different fragrance or ingredients can be added to each gel (e.g.
perfume in one gel and de-odorant in the other gel).
In an alternative embodiment of the present invention, multiple pieces of fragranced gel, preferably in the form of small beads or other similar designs, may be used.
Indeed, preferably the fragranced gel is present in the form of at least one, more preferably a multitude of fragranced gel beads. In such as preferred embodiment, such fragranced gel beads have an increased consistency and/or a limited stickiness, which prevents the single beads from agglomerating together and leaves the beads as substantially individual items. Beads herein may be of a regular globular or elliptical or even square shape or of an irregular rounded shape. Using beads maximizes the surface area of the pieces and facilitates the release of fragrance. These beads are preferably included in the dispenser in a recess in the surface of the dispenser and/or its outer casing (if any), wherein preferably said recess is covered using a gas-permeable cover, preferably a perforated cover. This gas-permeable cover holds the beads in place prior to usage. The covering may consist of a rigid plastic grid that may be clipped into the recess over the beads to hold it in place or a perforated film that is heat sealed or glued over the recess. A further alternative is to create a cage like device that holds the beads and can be attached to the dispenser or parts thereof via various means. Alternatively, the cage may be integrally molded into parts of the dispenser (or its outer casing, if any). Indeed, the beads may be placed within the dispenser, preferably in a separate compartment. A further alternative is to contain the beads in an open top container. This container may be positioned either adjacent to or above the said storage compartment. This allows the beads-container to be easily refilled along with the container for the liquid, perfumed composition because both containers could be inserted into the dispensing means at the same time.
In a preferred embodiment, such fragranced gel beads are self-disincarnating, wherein due to the release of perfume the gel beads are reduced in size over time. Suitable fragranced gel beads are commercially available from IFF.
In a preferred embodiment herein, one or a multitude of such fragranced gel beads are placed within the dispenser in a separate compartment and are preferably partially visible for a user due to the use of transparent material in making the dispenser or through openings.
For all embodiments herein containing a fragranced gel, and in particular for the embodiment herein, wherein the fragrance delivery component is at least one, preferably a multitude of fragranced gel beads, it is preferred that the fragranced gel is (preferably the fragranced gel beads are) colored.
For all of the fragranced gel-based embodiments, the fragranced gel may optionally but highly preferred be protected from releasing its fragrance into the atmosphere prior to usage of the dispenser. This can be solved by packaging the dispenser in a package that has a high gas barrier.
A preferred option would be a transparent thermoformed blister pack made from PET, PVC or other similar materials having a high oxygen barrier film over the top of the blister made from laminates of aluminum, metallised PET, metallised biaxially oriented polypropylene, EVOH, Polyamides (Nylon) and/or other similar film materials. An alternative would be to seal a high gas barrier peel-able film onto the dispenser (or its outer casing, if any) so that it covers the perfumed gel on the surface of the dispenser and/or its outer casing (if any), or alternatively onto the separate piece so that it covers the gel container within the separate piece or still alternatively onto the openings, holes, cut-outs or apertures of the dispenser and/or its outer casing (if any) permitting air flow between the fragrance delivery component and the ambiance.
This film would then be removed by the user upon the first use of the dispenser and/or its outer casing (if any).
Preferably, the peel-able film would be transparent to allow the consumer to also see the gel on shelf. A suitable film would be a laminated film using A1203, Si02, EVOH, Nylon or PVDC
coatings or other similar high gas barrier transparent films.
For all embodiments herein containing a fragranced gel, a highly preferred embodiment is to place the perfumed gel in a recess preferably on the outward-facing section of the dispenser and/or its outer casing (if any). By "outward-facing section" it is meant the visible outside portion of the dispenser and/or its outer casing (if any).
Frauanced Plastics In a preferred embodiment of the present invention, the fragrance delivery component herein may be a fragranced plastic that preferably continuously releases a fragrance for a prolonged period of time. More preferably, the fragrance delivery component herein is a perfumed plastic.
5 By "fragranced/ perfumed plastic" it is meant herein any plastic material that contains a fragrance/ perfume and is capable of releasing the fragrance/ perfume into the atmosphere of the bathroom or lavatory.
Fragranced plastics include any type of plastic material suitable to release a fragrance. Preferably, 10 suitable plastic materials for use as a fragranced plastic are selected from the group consisting of :
polyethylene terephthalate (PET); polyethylene (PE); polypropylene (PP);
polyvinyl chloride (PVC); high impact polystyrene (HIPS); polystyrene (PS), thermoplastic elastomers (TPE), ethyl vinyl acetate (EVA) and the like.
15 The plastic material herein contains a fragranced, preferably perfumed, masterbatch. By "fragranced masterbatch" it is meant herein a portion of material consisting of a carrier resin such as PET, PE, PP, PVC, HIPS and/or PS and a high level of fragrance (preferably perfume) preferably up to 95%, from 10% to 90%, more preferably from 50% to 85% by weight of the total masterbatch of a fragrance (preferably perfume). The masterbatch is added during the normal 20 manufacture of plastic pieces via additions in the extruder for injection molding, blow molding, sheet forming, blown film and other similar plastic processes. The plastics may also be foamed to maximize the amount of fragrance that may be added to the plastic piece and to further encourage its release into the atmosphere. The technology is detailed in WO 00/08095, US
4,411,855, GB
2,180,157 and US 3,797,742.
The fragranced masterbatch herein may be used during the manufacture of the dispenser herein or parts thereof, such as the storage compartment, or the outer casing (if any).
This creates a dispenser that delivers a fragrance into the atmosphere upon use by releasing a fragrance directly from either the dispenser or parts thereof. Preferably, the fragranced masterbatch is used during the manufacture of the outer casing herein.
An alternative approach is to use the fragranced masterbatch for the manufacture of a separate plastic piece or pieces. This piece(s) ("insert(s)") may then be fastened to any part of the dispenser and/or its outer casing (if any). The insert (or inserts) may be injection molded or manufactured by similar plastic processes. This method of using a separate insert as compared to using the fragranced masterbatch for the manufacture of the dispenser itself has the advantage of allowing more control of the amount of fragrance as well as control of the type of plastic used to maximize the amount of fragrance delivery. This is due to the fact that these plastic piece(s) only need to dispense fragrance. They do not need to have additional functions such as to provide stability to the dispenser. In addition, the plastic pieces may be coloured and/or may be made from different designs to provide aesthetic improvements. Fastening of such inserts may be achieved by clipping the separate piece(s) to parts of the dispenser and/or its outer casing (if any), or by using adhesive or similar techniques. Such pieces could be sold as refills either in a separate package or in a multi-pack combined with a detergent unit-doses refill. Both packs would have a high oxygen barrier package (as described herein above) to keep the fragrance in the pieces prior to usage.
In an alternative embodiment of the present invention, multiple pieces of fragranced plastic, preferably in the form of small beads or other similar designs, may be used.
Beads herein may be of a regular globular or elliptical or even square shape or of an irregular rounded shape. Using fragranced plastic beads maximizes the surface area of the pieces and facilitates the release of fragrance. These beads are preferably included in the dispenser in a recess in the surface of the dispenser and/or its outer casing (if any), wherein preferably said recess is covered using a gas-permeable cover, preferably a perforated cover. This gas-permeable cover holds the beads in place prior to usage. The covering may consist of a rigid plastic grid that may be clipped into the recess over the beads to hold it in place or a perforated film that is heat sealed, stretch- or shrink-wrapped or glued over the recess. A further alternative is to create a cage like device that holds the beads and can be attached to the dispenser or parts thereof via various means. Alternatively, the cage may be integrally molded into parts of the dispenser (or its outer casing, if any). Indeed, the beads may be placed within the dispenser, preferably in a separate compartment. A further alternative is to contain the beads in an open top container. This container may be positioned either adjacent to or above the said storage compartment. This allows the beads-container to be easily refilled along with the container for the liquid, perfumed composition because both containers could be inserted into the dispensing means at the same time. In addition, the fragranced plastic beads may be colored and/or may be made from different designs.
In a preferred embodiment herein, one or a multitude of such fragranced plastic beads are placed within the dispenser in a separate compartment and are preferably partially visible for a user due to the use of transparent material in making the dispenser or through openings.
Permeable Films In a preferred embodiment of the present invention, the fragrance delivery component herein may be a permeable film delivery system over a fragrance-releasing medium.
By "permeable film" it is meant herein a film-based material that has a high permeation rate to fragrance. Preferably said permeable film is a film-based material that has a high permeation rate to fragrance or a micro porous membrane material (preferable with a hydrophobic coating) that has sufficient voids within the film structure to allow the passage of perfume to the atmosphere.
These films allows perfume vapor to escape the dispenser herein to the bathroom / lavatory atmosphere while preventing the fragrance / perfume, if any, to escape. They also allow control of the release rate of fragrance from the dispenser since the release rate can be controlled by film thickness and film / membrane material section. Suitable permeable films include highly permeable films such as low density polyethylene (LDPE), ethyl vinyl acetate (EVA), and the like, along with micro porous membranes such as those supplied by Gelman, Gore, Pall and other similar membrane suppliers. This technology is described in US 4,898,328, WO
97/42983 and EP-A-O 596 212.
By "fragrance releasing medium", it is meant herein a medium that is capable of releasing a fragrance, preferably perfume, over a prolonged period of time. Suitable fragrance releasing mediums are selected from the group consisting of : fragranced gels as described herein above;
fragranced plastics including beads as described herein above; and fragrance-containing liquid compositions preferably solvent based liquid compositions containing alcohols and other volatile ingredients; and pads impregnated with a fragrance-containing liquid composition; and combinations thereof.
The fragrance releasing medium herein with a covering permeable film may be placed directly into any appropriate position within the dispenser of the present invention, including combining the perfume releasing medium with a covering permeable film into the interior or exterior of the dispenser and/or the inside or outside portion of its outer casing, if any. In a preferred embodiment herein, the fragrance-releasing medium is contained in a recess on the outer surface of the dispenser herein and the recess is covered with a permeable film.
Alternatively, the fragrance-releasing medium is contained in an open top container and covered with a permeable film. This container may be positioned either adjacent to or above the storage compartment. This allows the container for the fragrance-releasing medium sealed with a permeable film to be easily refilled. Alternatively, a small flat container for the perfume-releasing medium sealed with permeable film may be attached directly to the surface of the dispenser herein or a part thereof, by a clipping mechanism, or an adhesive or similar method.
For all of the permeable film based embodiments, the product contained by the film may be protected from releasing its perfume into the atmosphere prior to purchase and usage of the dispenser. This can be achieved by packaging the dispenser in a package that has a high gas barrier as described herein above in the section titled "Fragranced gel".
In a preferred embodiment, a high barrier film would be laminated directly to the permeable film such that this film exists as a single structure. The bond between the barrier film and the permeable film would be very low such that when the film structure is sealed to the dispenser to encase the fragrance releasing medium, the bond between the permeable film and the dispenser is higher as compared to the bond between the permeable film and the barrier film and the bond between the permeable film and the barrier film is sufficiently low to allow easy peeling by the user. This system not only allows the user to easily remove the barrier film prior to using the dispenser, but also provides a much simpler manufacturing means to seal the permeable and barrier film in one simple step onto the dispenser.
Wicks In a preferred embodiment of the present invention, the fragrance delivery component herein may be a wick delivery system comprising fragrance-containing liquid composition.
More preferably, the fragrance delivery component herein is a wick delivery system comprising a perfumed liquid composition.
By "wick delivery system" it is meant herein a system wherein an absorbent substrate ("wick"), such a cotton or similar material, is part of a container wherein one end of the wick lies in a liquid composition containing a fragrance, preferably a perfume, while the other end of the wick lies either outside or at the very top of the opening of the container, and wherein the wick draws the fragrance-containing liquid into the wick via capillary forces and transports it to the end of the wick situated at the opening of the container. This causes the liquid composition containing a fragrance to evaporate and therefore the liquid continuously releases fragrance into the atmosphere of the bathroom/lavatory. Wick technology is well know in the prior art and is described in US 5,014,912, US 6,514,467 and US 5,000,383.
In a preferred embodiment herein, a wick delivery system being a container such as a bottle, having an opening and holding a volatile liquid containing a perfume wherein the container additionally contains a wick is part of the dispenser herein. This includes a container of a wick delivery system attached to the dispenser and/or its outer casing (if any).
The bottle may be attached to the dispenser and/or its outer casing (if any) via clipping, adhesive tape etc.
The container of a wick delivery system itself can additionally be sold as a sealed unit with a cap as a refill.
Battery powered / electrical fragrance release systems and gravity driven fragrance release cartrikes In a preferred embodiment of the present invention, the fragrance delivery component herein may be a battery powered / electrical fragrance release system or a gravity driven fragrance release cartridge. In this embodiment the dispenser herein contains a system that dispenses fragrance using an electrically or battery powered means to dispense a fragrance, preferably a perfume.
Alternatively, fragrance is released through a membrane from a cartridge by means of gravity.
5 Any means suitable to dispense a fragrance using an electrically or battery powered means can be used herein. Preferably, said battery / electrical fragrance release system is an electrical or battery driven pumping means that distributes a fragrance over a prolonged period of time. In a highly preferred embodiment, said battery / electrical fragrance release system includes a cartridge for housing a liquid composition comprising a fragrance, a means for releasing the liquid 10 composition from the cartridge and a means for forcing the liquid out of the cartridge using a gas-generating cell. The gas-generating cell herein preferably is an electrochemical cell (battery) that generates gas over a prolonged period of time. The means for forcing the liquid out of the cartridge is preferably a piston pump that presses the liquid composition comprising a perfume out of the cartridge. Suitable gas-generating cells as well as battery /
electrical fragrance release 15 system are described in US 6,045,055, US 6,109,539, WO 97/13007, WO
99/06614, WO
00/72951, US 5,681,435, US 5,899,381, WO 02/069935, WO 00/76645 and WO
02/16048. The above reference encompasses also gravity driven fragrance release cartridges.
Such gravity driven fragrance release cartridges may also be included as fragrance delivery components according to the present invention.
In a preferred embodiment of the present invention, a battery/electrical fragrance release system or gravity driven fragrance release cartridge is contained in the dispenser herein. Indeed, the battery/electrical fragrance release system or a gravity driven fragrance release cartridge may be combined with the dispenser and/or its outer casing. The battery/electrical fragrance release system or gravity driven fragrance release cartridge may be attached to the dispenser via clipping, adhesive tape, etc. Furthermore, the battery/electrical fragrance release system or gravity driven fragrance release cartridge may be housed in a separate compartment that is part of the dispenser herein.
The battery powered/electrical fragrance release system or gravity driven fragrance release cartridge may be sold as a separate refill device to be combined with the dispenser. Refills may be sold either separately or in a multi pack with the detergent unit-dose refills to provide continuity of fragrance.
Other fragrance delive components Other suitable fragrance delivery components herein include Piezo fragrance dispensing technology and aerosol dispensers integrated into the dispenser.

The detergent unit-doses provide a cleaning, disinfecting and/or deodorizing effect on the surfaces to which they are applied (preferably upon dissolution in water).
Indeed, the detergent unit-doses are typically dispensed into an effective amount of water and dissolve therein to provide a cleaning, disinfecting and/or deodorizing solution. Indeed, the detergent unit-doses are used to clean in their dissolved form. By "in their dissolved form" it is meant herein that the detergent unit-dose herein may be dissolved in up to 5000 times its weight in water dissolution level, preferably from 5 times to 5000 times its weight in water, more preferably from 7 times to 2500 times its weight in water, even more preferably from 10 times to 1000 times its weight in water, and most preferably from 20 to 500 times its weight in water.
Upon use by the end-user, a single detergent unit-dose or a multitude (preferably 2 or 3) of detergent unit-doses are dispensed for one cleaning operation.
By a "detergent unit-dose" it is meant herein a detergent article providing a predefined dosage of said detergent (i.e., a single dose), as compared to free-flowing liquid, solid or granular compositions that have to be metered. The detergent unit-dose may be or contain a detergent composition of any form, such as liquids (incl. pastes) and solids (compressed or non-compressed) as well as combinations thereof. Indeed, detergent unit-doses encompass water-soluble capsules filled with a liquid composition. Furthermore, detergent unit-doses herein are not limited in term of their compressibility or rigidity. Indeed, detergent unit-doses based on water-soluble capsules filled with liquid and/or solid compositions may to a certain degree be compressible and less rigid detergent portions are expressly not excluded from the scope of the present invention.
Detergent unit-doses include tablets. Suitable tablets herein include tablets made from compressed powders and/or granules, solidified molten material, extruded material and combinations thereof, such as a compressed moulded tablet wherein the mould is filled by solidified molten material. Detergent tablets and their manufacture are well known to the skilled person, e.g., WO 98/54283 relates to swelling agents for use in detergent tablets.

by Dow Chemicals; thermoplastic polyesters, also known as polyether ester copolymers, such as those produced under the trade names HYTREL by DuPont and ARNITEL by DSM, and thermoplastic polyamides, also known as polyether amide copolymers, such as those produced under the trade name PEBAX by Atofina.
In the highly preferred embodiment of the present invention, the fragranced plastic herein is a polymeric composition obtained by combining a low melting point polyamide polymer with a polar thermoplastic elastomer as described above, the fragrance is a perfume composition obtained by combining an ester terminated polyamide, a thermoplastic polyether amide copolymer and a perfume, according to the method described in US-A1-2006/0099168.
In the preferred embodiment herein, wherein the fragrance delivery component herein is a fragranced gel, the fragranced gel, preferably initially, comprises up to 95%, preferably from 10%
to 95%, more preferably from 50% to 95% by weight of fragrance, preferably perfume.
The shape of the gel may be any design suitable to deliver a fragrance into the ambiance. The fragranced gel may be placed directly into any appropriate position or portion on the dispenser.
This includes combining the fragranced gel with the dispenser and/or the outside portion of the storage compartment and/or with its outer casing, if any. For combining the fragranced gel with the dispenser and/or the outside portion of the storage compartment and/or with its outer casing, if any, a recess may be created on the outer surface of the dispenser and/or the outside portion of the storage compartment and/or with the outer casing, if any, to create a region that may be filled with fragranced gel. This recess can easily be created during the dispenser forming process (e.g., via extrusion blow molding, extrusion stretch blow molding, injection molding, thermoforming or vacuum forming process). The recess may be molded into the outer surfaces of the dispenser or its outer casing, if any (on its front panel, top panel, sides, bottom or back panel, if any). This recess is filled with liquid fragranced gel, which is solidified into the recess. Alternatively a recess could be created on the outer surface of the storage compartment. For pieces, which are typically injection molded, blow molded, thermoformed or vacuum formed, a recess can easily be created within the surface of the piece during the molding process itself.
Alternatively, the fragranced gel may be cast as a separate strip and attached into a recesses on the surface of the dispenser and/or its outer casing (if any), via a variety of different means, such as adhesives. Alternatively, the gel may be attached directly to the surface of dispenser and/or its outer casing (if any) without a recess using the same attachment means mentioned above or the dispenser and/or its outer casing (if any) or parts thereof may be fully or partially coated with the fragranced gel by either dipping or spraying the fragranced gel on the surface of the dispenser and/or its outer casing (if any). Alternatively, the fragranced gel may be filled into a separate piece containing a complementary recess to that placed in the surface of the dispenser and/or outer casing (if any), or the fragranced gel may be cast as a separate sheet or strip and attached to such a separate piece. This separate piece is then fastened onto the outer surface of dispenser and/or its outer casing (if any), by clipping the piece into a recess in the outer surface of dispenser and/or its outer casing (if any) or by adhesives or various other means. This separate piece containing the fragranced gel may be sold separately or in combination with the dispenser. The separate piece would therefore be refilled in the dispenser either separately or at the same time as when the storage compartment is refilled with detergent unit-doses.
In a highly preferred embodiment herein, said fragrance delivery component is a fragranced gel, preferably a perfumed gel, which is preferably present in a recess on the outside portion of the dispenser and/or its outer casing (if any).
In the preferred embodiments, wherein the fragranced gel is present in a recess of the dispenser and/or its outer casing (if any) herein, setting the fragranced gel into the recess may be achieved by pouring the heated fragranced gel directly into the recess and allowing it to cool. A small peel-able and preferably transparent film with a high barrier may be placed over the fragranced gel in the recess and sealed to the outer part of the recess in the dispenser and/or its outer casing (if any). This embodiment has the advantage that it protects the fragranced gel prior to use. Indeed, the fragranced gel is replaced at the same time as when the dispenser is replaced, and the peel-able film is removed to expose the gel upon first use.
In addition, two or more layers of gel may be filled on top of each other.
This has the advantage of the lower layer acting as an adhesive to the upper layers. This can more effectively stick the fragranced gel into the dispenser and/or its outer casing (if any) so that is does not drop out due to mechanical agitation, or to prevent undue shrinkage of the gel as the fragrance evaporates. In addition, the level (%) of fragrance can be altered in these layers to better control the release of fragrance from the gel. Alternatively, two or more different gels can be cast into the dispenser herein (or its outer casing, if any) side by side. This has the advantage of creating better aesthetics for the consumer. In addition, different fragrance or ingredients can be added to each gel (e.g.
perfume in one gel and de-odorant in the other gel).
In an alternative embodiment of the present invention, multiple pieces of fragranced gel, preferably in the form of small beads or other similar designs, may be used.
Indeed, preferably the fragranced gel is present in the form of at least one, more preferably a multitude of fragranced gel beads. In such as preferred embodiment, such fragranced gel beads have an increased consistency and/or a limited stickiness, which prevents the single beads from agglomerating together and leaves the beads as substantially individual items. Beads herein may be of a regular globular or elliptical or even square shape or of an irregular rounded shape. Using beads maximizes the surface area of the pieces and facilitates the release of fragrance. These beads are preferably included in the dispenser in a recess in the surface of the dispenser and/or its outer casing (if any), wherein preferably said recess is covered using a gas-permeable cover, preferably a perforated cover. This gas-permeable cover holds the beads in place prior to usage. The covering may consist of a rigid plastic grid that may be clipped into the recess over the beads to hold it in place or a perforated film that is heat sealed or glued over the recess. A further alternative is to create a cage like device that holds the beads and can be attached to the dispenser or parts thereof via various means. Alternatively, the cage may be integrally molded into parts of the dispenser (or its outer casing, if any). Indeed, the beads may be placed within the dispenser, preferably in a separate compartment. A further alternative is to contain the beads in an open top container. This container may be positioned either adjacent to or above the said storage compartment. This allows the beads-container to be easily refilled along with the container for the liquid, perfumed composition because both containers could be inserted into the dispensing means at the same time.
In a preferred embodiment, such fragranced gel beads are self-disincarnating, wherein due to the release of perfume the gel beads are reduced in size over time. Suitable fragranced gel beads are commercially available from IFF.
In a preferred embodiment herein, one or a multitude of such fragranced gel beads are placed within the dispenser in a separate compartment and are preferably partially visible for a user due to the use of transparent material in making the dispenser or through openings.
For all embodiments herein containing a fragranced gel, and in particular for the embodiment herein, wherein the fragrance delivery component is at least one, preferably a multitude of fragranced gel beads, it is preferred that the fragranced gel is (preferably the fragranced gel beads are) colored.
For all of the fragranced gel-based embodiments, the fragranced gel may optionally but highly preferred be protected from releasing its fragrance into the atmosphere prior to usage of the dispenser. This can be solved by packaging the dispenser in a package that has a high gas barrier.
A preferred option would be a transparent thermoformed blister pack made from PET, PVC or other similar materials having a high oxygen barrier film over the top of the blister made from laminates of aluminum, metallised PET, metallised biaxially oriented polypropylene, EVOH, Polyamides (Nylon) and/or other similar film materials. An alternative would be to seal a high gas barrier peel-able film onto the dispenser (or its outer casing, if any) so that it covers the perfumed gel on the surface of the dispenser and/or its outer casing (if any), or alternatively onto the separate piece so that it covers the gel container within the separate piece or still alternatively onto the openings, holes, cut-outs or apertures of the dispenser and/or its outer casing (if any) permitting air flow between the fragrance delivery component and the ambiance.
This film would then be removed by the user upon the first use of the dispenser and/or its outer casing (if any).
Preferably, the peel-able film would be transparent to allow the consumer to also see the gel on shelf. A suitable film would be a laminated film using A1203, Si02, EVOH, Nylon or PVDC
coatings or other similar high gas barrier transparent films.
For all embodiments herein containing a fragranced gel, a highly preferred embodiment is to place the perfumed gel in a recess preferably on the outward-facing section of the dispenser and/or its outer casing (if any). By "outward-facing section" it is meant the visible outside portion of the dispenser and/or its outer casing (if any).
Frauanced Plastics In a preferred embodiment of the present invention, the fragrance delivery component herein may be a fragranced plastic that preferably continuously releases a fragrance for a prolonged period of time. More preferably, the fragrance delivery component herein is a perfumed plastic.
5 By "fragranced/ perfumed plastic" it is meant herein any plastic material that contains a fragrance/ perfume and is capable of releasing the fragrance/ perfume into the atmosphere of the bathroom or lavatory.
Fragranced plastics include any type of plastic material suitable to release a fragrance. Preferably, 10 suitable plastic materials for use as a fragranced plastic are selected from the group consisting of :
polyethylene terephthalate (PET); polyethylene (PE); polypropylene (PP);
polyvinyl chloride (PVC); high impact polystyrene (HIPS); polystyrene (PS), thermoplastic elastomers (TPE), ethyl vinyl acetate (EVA) and the like.
15 The plastic material herein contains a fragranced, preferably perfumed, masterbatch. By "fragranced masterbatch" it is meant herein a portion of material consisting of a carrier resin such as PET, PE, PP, PVC, HIPS and/or PS and a high level of fragrance (preferably perfume) preferably up to 95%, from 10% to 90%, more preferably from 50% to 85% by weight of the total masterbatch of a fragrance (preferably perfume). The masterbatch is added during the normal 20 manufacture of plastic pieces via additions in the extruder for injection molding, blow molding, sheet forming, blown film and other similar plastic processes. The plastics may also be foamed to maximize the amount of fragrance that may be added to the plastic piece and to further encourage its release into the atmosphere. The technology is detailed in WO 00/08095, US
4,411,855, GB
2,180,157 and US 3,797,742.
The fragranced masterbatch herein may be used during the manufacture of the dispenser herein or parts thereof, such as the storage compartment, or the outer casing (if any).
This creates a dispenser that delivers a fragrance into the atmosphere upon use by releasing a fragrance directly from either the dispenser or parts thereof. Preferably, the fragranced masterbatch is used during the manufacture of the outer casing herein.
An alternative approach is to use the fragranced masterbatch for the manufacture of a separate plastic piece or pieces. This piece(s) ("insert(s)") may then be fastened to any part of the dispenser and/or its outer casing (if any). The insert (or inserts) may be injection molded or manufactured by similar plastic processes. This method of using a separate insert as compared to using the fragranced masterbatch for the manufacture of the dispenser itself has the advantage of allowing more control of the amount of fragrance as well as control of the type of plastic used to maximize the amount of fragrance delivery. This is due to the fact that these plastic piece(s) only need to dispense fragrance. They do not need to have additional functions such as to provide stability to the dispenser. In addition, the plastic pieces may be coloured and/or may be made from different designs to provide aesthetic improvements. Fastening of such inserts may be achieved by clipping the separate piece(s) to parts of the dispenser and/or its outer casing (if any), or by using adhesive or similar techniques. Such pieces could be sold as refills either in a separate package or in a multi-pack combined with a detergent unit-doses refill. Both packs would have a high oxygen barrier package (as described herein above) to keep the fragrance in the pieces prior to usage.
In an alternative embodiment of the present invention, multiple pieces of fragranced plastic, preferably in the form of small beads or other similar designs, may be used.
Beads herein may be of a regular globular or elliptical or even square shape or of an irregular rounded shape. Using fragranced plastic beads maximizes the surface area of the pieces and facilitates the release of fragrance. These beads are preferably included in the dispenser in a recess in the surface of the dispenser and/or its outer casing (if any), wherein preferably said recess is covered using a gas-permeable cover, preferably a perforated cover. This gas-permeable cover holds the beads in place prior to usage. The covering may consist of a rigid plastic grid that may be clipped into the recess over the beads to hold it in place or a perforated film that is heat sealed, stretch- or shrink-wrapped or glued over the recess. A further alternative is to create a cage like device that holds the beads and can be attached to the dispenser or parts thereof via various means. Alternatively, the cage may be integrally molded into parts of the dispenser (or its outer casing, if any). Indeed, the beads may be placed within the dispenser, preferably in a separate compartment. A further alternative is to contain the beads in an open top container. This container may be positioned either adjacent to or above the said storage compartment. This allows the beads-container to be easily refilled along with the container for the liquid, perfumed composition because both containers could be inserted into the dispensing means at the same time. In addition, the fragranced plastic beads may be colored and/or may be made from different designs.
In a preferred embodiment herein, one or a multitude of such fragranced plastic beads are placed within the dispenser in a separate compartment and are preferably partially visible for a user due to the use of transparent material in making the dispenser or through openings.
Permeable Films In a preferred embodiment of the present invention, the fragrance delivery component herein may be a permeable film delivery system over a fragrance-releasing medium.
By "permeable film" it is meant herein a film-based material that has a high permeation rate to fragrance. Preferably said permeable film is a film-based material that has a high permeation rate to fragrance or a micro porous membrane material (preferable with a hydrophobic coating) that has sufficient voids within the film structure to allow the passage of perfume to the atmosphere.
These films allows perfume vapor to escape the dispenser herein to the bathroom / lavatory atmosphere while preventing the fragrance / perfume, if any, to escape. They also allow control of the release rate of fragrance from the dispenser since the release rate can be controlled by film thickness and film / membrane material section. Suitable permeable films include highly permeable films such as low density polyethylene (LDPE), ethyl vinyl acetate (EVA), and the like, along with micro porous membranes such as those supplied by Gelman, Gore, Pall and other similar membrane suppliers. This technology is described in US 4,898,328, WO
97/42983 and EP-A-O 596 212.
By "fragrance releasing medium", it is meant herein a medium that is capable of releasing a fragrance, preferably perfume, over a prolonged period of time. Suitable fragrance releasing mediums are selected from the group consisting of : fragranced gels as described herein above;
fragranced plastics including beads as described herein above; and fragrance-containing liquid compositions preferably solvent based liquid compositions containing alcohols and other volatile ingredients; and pads impregnated with a fragrance-containing liquid composition; and combinations thereof.
The fragrance releasing medium herein with a covering permeable film may be placed directly into any appropriate position within the dispenser of the present invention, including combining the perfume releasing medium with a covering permeable film into the interior or exterior of the dispenser and/or the inside or outside portion of its outer casing, if any. In a preferred embodiment herein, the fragrance-releasing medium is contained in a recess on the outer surface of the dispenser herein and the recess is covered with a permeable film.
Alternatively, the fragrance-releasing medium is contained in an open top container and covered with a permeable film. This container may be positioned either adjacent to or above the storage compartment. This allows the container for the fragrance-releasing medium sealed with a permeable film to be easily refilled. Alternatively, a small flat container for the perfume-releasing medium sealed with permeable film may be attached directly to the surface of the dispenser herein or a part thereof, by a clipping mechanism, or an adhesive or similar method.
For all of the permeable film based embodiments, the product contained by the film may be protected from releasing its perfume into the atmosphere prior to purchase and usage of the dispenser. This can be achieved by packaging the dispenser in a package that has a high gas barrier as described herein above in the section titled "Fragranced gel".
In a preferred embodiment, a high barrier film would be laminated directly to the permeable film such that this film exists as a single structure. The bond between the barrier film and the permeable film would be very low such that when the film structure is sealed to the dispenser to encase the fragrance releasing medium, the bond between the permeable film and the dispenser is higher as compared to the bond between the permeable film and the barrier film and the bond between the permeable film and the barrier film is sufficiently low to allow easy peeling by the user. This system not only allows the user to easily remove the barrier film prior to using the dispenser, but also provides a much simpler manufacturing means to seal the permeable and barrier film in one simple step onto the dispenser.
Wicks In a preferred embodiment of the present invention, the fragrance delivery component herein may be a wick delivery system comprising fragrance-containing liquid composition.
More preferably, the fragrance delivery component herein is a wick delivery system comprising a perfumed liquid composition.
By "wick delivery system" it is meant herein a system wherein an absorbent substrate ("wick"), such a cotton or similar material, is part of a container wherein one end of the wick lies in a liquid composition containing a fragrance, preferably a perfume, while the other end of the wick lies either outside or at the very top of the opening of the container, and wherein the wick draws the fragrance-containing liquid into the wick via capillary forces and transports it to the end of the wick situated at the opening of the container. This causes the liquid composition containing a fragrance to evaporate and therefore the liquid continuously releases fragrance into the atmosphere of the bathroom/lavatory. Wick technology is well know in the prior art and is described in US 5,014,912, US 6,514,467 and US 5,000,383.
In a preferred embodiment herein, a wick delivery system being a container such as a bottle, having an opening and holding a volatile liquid containing a perfume wherein the container additionally contains a wick is part of the dispenser herein.
