Unit dose detergent dispenser with fragrance assembly

technical field

The present invention relates to a dispenser for unit doses of detergent comprising: a) a storage compartment containing at least one unit dose of detergent; b) a dispensing member for dispensing said unit dose of detergent; and c) a fragrance drug delivery components. The dispensers herein provide excellent fragrance delivery performance.

Background technique

Detergent unit doses represent a convenient way of delivering detergent products to the end user. In fact, end users can directly use such detergent unit doses including tablets and water-soluble capsules (including solid and/or liquid compositions), eliminating the need for end users to determine in grams or milliliters of detergent Trouble with adequate dosage. Manufacturers of such detergent unit doses provide simplified instructions directing the end user to use one, two or more such detergent unit doses. Thus, detergent unit doses are the preferred detergent form for many end users.

Detergent unit doses are available in hard surface cleaning areas, e.g. in all-purpose cleaners, floor cleaners and toilet bowl cleaners.

Containers for such detergent unit doses are well known in the art. In fact, tablets are often packaged in cartons or plastic bottles. Water-soluble capsules comprising solid and/or liquid compositions can be packaged in plastic bottles or bags. WO 03/047998 describes plastic bags for water soluble capsules.

A known drawback of currently known containers for such detergent unit doses (eg cartons, plastic bottles, plastic bags etc.) is that they are not convenient for the end user to dispense detergent unit doses. In practice, an end user attempting to use a unit dose of detergent must open the container and remove one or more of the portions from the container with his fingers.

In addition to the drawbacks of current unit-dose containers when dispensing detergent unit-doses, it is also desirable for such containers to deliver fragrances (i.e., fragrances) to the room atmosphere or ambient air in which such containers are stored and/or used. and/or deodorant). In fact, such places, including toilets, bathrooms, kitchens, basements, garages, cleaning tool storage rooms, etc., are prone to develop undesirable or unpleasant odors due to the activities performed in them and/or the presence of Contaminated hard surfaces and/or other items stored on them. This applies in particular to bathrooms and/or toilets due to the presence of toilets and urinals in such establishments.

In light of the above, it is therefore an object of the present invention to provide a container for detergent unit doses which provides for continuous delivery of fragrance (i.e. fragrance and/or deodorant) to the atmosphere in which the dispenser is used/stored. room ambient air) in combination with a convenient way of dispensing unit doses of the detergent.

It has now been found that the above objects can be met by a dispenser for detergent unit doses according to the present invention, wherein fragrance (i.e. fragrance and/or deodorant) is continuously dispensed into the ambient air, and wherein all The containers described above provide a convenient means of dispensing unit doses of detergent.

Advantageously, a dispenser according to the invention also improves the handling of detergent unit doses by the end user. Indeed, often detergent unit doses are individually packaged within flow packs to protect them from moisture or degradation (especially in the case of tablets). Opening such flow packages is often messy as the operation requires the end user to touch the product. With the dispensers herein, each detergent unit dose does not need to be individually packaged, which simplifies dispensing of the detergent unit dose by the end user. Furthermore, due to the use of the dispenser herein, the end user does not have to touch the detergent unit dose, thereby avoiding direct contact, which has a beneficial effect on the stability of the detergent unit dose and reduces skin irritation caused by the detergent unit dose. The possibility of stimulation.

Summary of the invention

The present invention includes a dispenser for unit doses of detergent comprising:

a) a storage compartment comprising at least one unit dose of detergent;

b) dispensing means for dispensing unit doses of said detergent from said storage compartment; and

c) a fragrance delivery component;

Wherein said fragrance delivery assembly delivers fragrance independent of said at least one detergent unit dose and delivers said fragrance to the environment long-term.

The present invention also includes a method of administering a unit dose of bowl cleaning detergent into a bowl, wherein the method comprises dispensing the unit dose of bowl cleaning detergent into the bowl from a dispenser according to the invention in the steps.

Furthermore, the present invention also includes a method for deodorizing ambient air in a toilet, wherein said method comprises the step of continuously dispensing fragrance from a dispenser according to the invention into the ambient air in the toilet.

In a highly preferred embodiment of the present invention, the scented plastic herein is a polymer composition obtained by combining a low-melting polyamide polymer with a polar thermoplastic elastomer as described above, the fragrance is according to US - Perfume composition obtained by combining ester-terminated polyamide, thermoplastic polyetheramide copolymer and perfume according to the method described in A1-2006/0099168.

In preferred embodiments herein wherein the fragrance delivery component herein is a fragrance gel, said fragrance gel preferably initially comprises up to 95%, preferably from 10% to 95%, more preferably from 50% to 95% by weight. % of fragrances (preferably fragrances).

The shape of the gel can be any design suitable for delivering fragrance to the environment. The deodorant gel can be placed directly on the dispenser in any convenient location or section. This includes combining the scenting gel with the dispenser and/or the outer part of the storage compartment and/or its outer casing (if present). In order to combine the deodorant gel with the outer part of the dispenser and/or the storage compartment and/or its outer casing (if any), an outer surface of the dispenser and/or the outer part of the storage compartment and and/or the outer shell (if present) is grooved to create an area that can be filled with a scenting gel. Such grooves can be readily produced during the formation of the dispenser (eg, by extrusion blow molding, extrusion stretch blow molding, injection molding, thermoforming or vacuum forming processes). Grooves may be molded into the outer surface of the dispenser or its outer housing (if any) (on its front, top, side, bottom or rear panels, if any). The groove is filled with a liquid scented gel that solidifies into the groove. Alternatively, grooves may be created on the outer surface of the storage compartment. For sheets that are typically injection molded, blow molded, thermoformed or vacuum formed, grooves can easily be created in the surface of the sheet during the molding process of the sheet itself.

Alternatively, the scented gel can be cast as a single strip and attached to the outer surface of the dispenser and/or its outer housing (if present) by a variety of different components (such as adhesives) in the groove on the Alternatively, the gel can be attached directly to the surface of the dispenser and/or its outer housing (if any) without grooves, or the dispenser and and/or its outer casing (if any) may be fully or partially coated with deodorant gel by dipping or spraying the deodorant gel into the dispenser and/or its outer casing (if if any) on the surface. Alternatively, the scenting gel may be filled into a separate sheet comprising complementary grooves placed in the surface of the dispenser and/or outer housing (if present), or the scenting gel Can be cast as individual sheets or strips connected to such individual sheets. Subsequently, the separate sheet is fastened to the outer surface of the dispenser and/or its outer casing (if any) by clamping the sheet to the dispenser and/or its outer casing ( if present) or by adhesive or various other means. This individual sheet containing the deodorant gel is sold alone or in combination with a dispenser. The separate tablet will thus be refilled into the dispenser either alone or simultaneously with the refilling of the storage compartment with the detergent unit dose.

In a highly preferred embodiment herein, the fragrance delivery component is a perfuming gel, preferably a perfuming gel, which gel is preferably present in the dispenser and/or its outer housing (if any). words) in the groove on the outside.

In preferred embodiments where the scenting gel is present in the recess of the dispenser herein and/or its outer housing (if any), this can be achieved by pouring the heated scenting gel directly into the recess and Allow to cool to set the scenting gel into the groove. A small piece of peelable and preferably transparent high barrier film can be placed over the scented gel in the recess and sealed to the outside of the recess in the dispenser and/or its outer housing (if present) partly on. This embodiment has the advantage of protecting the deodorant gel before use. In effect, the scented gel is replaced at the same time the dispenser is replaced, and the peel-off film is removed to expose the gel upon initial use.

Additionally, two or more layers of gel can be filled on top of each other. This has the advantage that the lower layer acts as a binder for the upper layer. This more effectively adheres the fragrance gel to the dispenser and/or its outer housing (if present) so that it does not fall out due to mechanical agitation, or prevents improper gelation when the fragrance evaporates shrink. Furthermore, the amount (%) of fragrance in these layers can be varied to better control the release of fragrance from the gel. Alternatively, two or more different gels may be cast side-by-side into the dispenser herein (or its outer housing, if present). This has the advantage of resulting in a better aesthetic for the consumer. In addition, different fragrances or ingredients may be added to each gel (eg, fragrance in one gel and deodorant in another).

In an alternative embodiment of the present invention, multiple pieces of deodorant gel, preferably in the form of beads or other similar designs, may be used. Indeed, the deodorant gel is preferably present in the form of at least one, more preferably a plurality of deodorant gel beads. In such preferred embodiments, such fragrance gel beads have increased consistency and/or limited viscosity which prevents the individual beads from agglomerating together and makes the beads a substantially single object. The beads herein may be regular spherical or oval or even square or irregularly round. The use of beads maximizes the surface area of the tablet and facilitates the release of the fragrance. These beads are preferably included in the dispenser in recesses on the surface of the dispenser and/or its outer housing (if present), wherein the gas permeable cover, preferably a porous cover, is preferably used to cover the groove. This gas permeable cover holds the beads in place until use. The cover can consist of a rigid plastic mesh that can be clamped over beads in the grooves to hold the mesh in place, or a porous film that is heat sealed or glued. fit over the groove. Another alternative is to make a cage like device that holds the beads and can be attached to the dispenser or its components by various means. Alternatively, the cage may be integrally molded as part of the dispenser (or its outer housing, if present). In practice, the beads can be placed in a dispenser, preferably in a separate compartment. Another alternative is to contain the beads in an open top container. The container may be placed adjacent to or above the storage compartment. This makes it easy to refill the bead container together with the container for the liquid fragrance composition, as both containers can be inserted into the dispensing member at the same time.

In a preferred embodiment, such fragrance gel beads are self-disappearing, wherein the size of the gel beads decreases over time due to the release of fragrance. Suitable deodorant gel beads are commercially available from IFF.

In a preferred embodiment herein, one or more such scented gel beads are placed in a separate compartment within the dispenser and are preferably accessible to the user due to the use of transparent material from which the dispenser is made or through an opening. partially visible.

For all embodiments herein comprising a fragrance gel, in particular for embodiments herein wherein the fragrance delivery component is at least one, preferably a plurality of fragrance gel beads, preferably the fragrance gel (preferably the fragrance gel Glue beads) are colored.

As with all deodorant gel-based embodiments, the deodorant gel may optionally but highly preferably avoid releasing its fragrance into the atmosphere prior to use of the dispenser. This can be solved by packaging the dispenser in a highly gas barrier package. The preferred option would be a clear thermoformed blister pack made of PET, PVC or other similar material with a highly oxygen barrier film over the top of the blister made of aluminum, metallized PET, metallized Laminates of biaxially oriented polypropylene, EVOH, polyamide (nylon), and/or other similar film materials. An alternative is to seal the highly gas barrier peelable film to the dispenser (or its outer casing, if any) so that it covers the dispenser and/or its outer casing (if any) ) on the surface, or alternatively sealed to a separate sheet so that it covers the gel container within the separate sheet, or still alternatively sealed to the dispenser and/or its outer casing ( If any) openings, holes, cutouts or apertures that allow air to flow between the fragrance delivery assembly and the environment.

scented plastic

In a preferred embodiment of the present invention, the fragrance delivery component herein may be a scented plastic, preferably long-term continuous release of fragrance. More preferably, the fragrance delivery component herein is a scented plastic.

By "perfuming/perfuming plastic" is meant herein any plastic material that contains a fragrance/fragrance and is capable of releasing the fragrance/fragrance into the bathroom or toilet atmosphere.

Fragranced plastics include any type of plastic material suitable for releasing fragrances. Preferably, suitable plastic materials for use as scented plastics are selected from the group consisting of: polyethylene terephthalate (PET); polyethylene (PE); polypropylene (PP); polyvinyl chloride (PVC) ; High Impact Polystyrene (HIPS); Polystyrene (PS), Thermoplastic Elastomer (TPE), Ethyl Vinyl Acetate (EVA), etc.

The plastic material herein comprises a fragrance, preferably a fragrance masterbatch. The so-called "perfume masterbatch" herein refers to the material part composed of carrier resins such as PET, PE, PP, PVC, HIPS and/or PS and a high content of fragrance (preferably perfume) according to Preferably up to 95%, 10% to 90%, more preferably 50% to 85% fragrance (preferably fragrance) by weight of the total masterbatch. Masterbatch is added during the normal manufacture of plastic sheet by addition in extruders for injection molding, blow molding, sheet forming, blown film and other similar plastics processing. The plastic can also be foamed to maximize the amount of fragrance that can be added to the plastic sheet and further facilitate its release into the atmosphere. This technique is described in detail in WO00/08095, US 4,411,855, GB 2,180,157 and US 3,797,742.

The fragrance masterbatches herein may be used during the manufacture of the dispensers herein or components thereof (eg storage compartments) or outer housings (if any). This results in a dispenser that, in use, delivers fragrance to the atmosphere by releasing the fragrance directly from the dispenser or a component thereof. Preferably, a fragrance masterbatch is used during the manufacture of the outer casing herein.

An alternative approach is to utilize a fragrance masterbatch for the manufacture of individual one or more plastic sheets. This sheet ("insert") can then be fastened to any part of the dispenser and/or its outer housing (if present). The insert (or inserts) may be injection molded or manufactured by similar plastic processing methods. This method of using a separate insert has the advantage of allowing better control over the amount of fragrance as well as the type of plastic used to maximize the amount of fragrance delivered compared to using a fragrance masterbatch for the manufacture of the dispenser itself. This is due to the fact that these plastic sheets are only needed to dispense the fragrance. They do not have to have additional functions, such as providing stability to the dispenser. In addition, the plastic sheet can be colored and/or can be made of different designs to provide an aesthetic improvement. Fastening of such inserts may be achieved by clamping a separate sheet to parts of the dispenser and/or its outer housing (if present) or by use of adhesives or similar techniques. Such tablets may be sold as refills, either in separate packages or in multi-packs combined with detergent unit dose refills. Both packages will have a high oxygen barrier package (as described herein above) to keep the fragrance in the sheet until use.

In an alternative embodiment of the present invention, multiple pieces of scented plastic, preferably in the form of beads or other similar designs, may be used. The beads herein may be regular spherical or oval or even square or irregular round. The use of scented plastic beads maximizes the surface area of the tablet and facilitates the release of the fragrance. These beads are preferably included in the dispenser in recesses on the surface of the dispenser and/or its outer housing (if present), wherein the gas permeable cover, preferably a porous cover, is preferably used to cover the groove. This gas permeable cover holds the beads in place until use. The cover can consist of a rigid plastic mesh that can be clamped over the beads within the grooves to keep them in place, or a porous film that is heat sealed, stretch wrapped, or Shrink wrap or glue over groove. Another alternative is to make a cage like device that holds the beads and can be attached to the dispenser or its components by various means. Alternatively, the cage may be integrally molded into a part of the dispenser (or its outer housing, if present). In practice, the beads can be placed in a dispenser, preferably in a separate compartment. Another alternative is to contain the beads in an open top container. The container may be placed adjacent to or above the storage compartment. This makes the bead container easy to refill together with the container for the liquid fragrance composition, as both containers can be inserted into the dispensing member at the same time. Additionally, the scented plastic beads can be colored and/or can be made of different designs.

In a preferred embodiment herein, one or more such scented plastic beads are placed in a separate compartment within the dispenser and are preferably partially visible to the user due to the use of a transparent material from which the dispenser is made or through an opening .

permeable membrane

In a preferred embodiment of the present invention, the fragrance delivery component herein may be a permeable film delivery system on top of a fragrance release medium.

By "permeable film" is meant herein a film-based material that has a high permeation rate for fragrances.

In a preferred embodiment herein, the fragrance release medium is contained within a groove on the outer surface of the dispenser herein, and the groove is covered with a permeable membrane. Alternatively, the fragrance release medium is contained within an open top container and covered with a permeable membrane. The container may be placed adjacent to or above the storage compartment. This allows easy refilling of the container for the fragrance release medium sealed with the permeable membrane. Alternatively, a small flat container for a fragrance release medium sealed with a permeable membrane may be attached directly to the surface of the dispenser herein or a component thereof by a clamping mechanism, or adhesive or similar method.

As with all permeable film-based embodiments, the film contains a product that avoids releasing its fragrance to the atmosphere prior to purchase and use of the dispenser. This can be achieved by packaging the dispenser in a packaging having a high gas barrier property as described herein above in the section entitled "Fragrance Gel".

In a preferred embodiment, the highly barrier film will be laminated directly to the permeable film such that the film exists as a unitary structure. The bond between the barrier film and the permeable film will be so low that when the film structure is sealed to the dispenser to contain the fragrance release medium, the bond between the permeable film and the dispenser will be as low as possible. The bond between the permeable and barrier films is relatively high, and the bond between the permeable and barrier films is low enough to allow easy peeling by the user. This system not only allows the user to easily remove the barrier film prior to use of the dispenser, but also provides a simpler manufacturing component to seal the permeable and barrier films to the dispenser in one simple step.
