Definitions

• the present invention relates to the combination of a detergent container and an air freshener for detergent use and immediate and long lasting air treatment.
• Air fresheners are frequently used to control odors in bathrooms, kitchens and other enclosed spaces.
• Generally commercial dispensers for dispensing fragrances or air-freshening materials operate in an active mode or passive mode. Active dispensing is achieved by way of an aerosol or pump activated spray dispenser.
• dispensers which require an action on the part of the consumer to result in the immediate dispensing of the dispersible composition, dispensers which operates passively, through evaporation or sublimation of vaporizable substances, without active physical participation by the consumers, are also well known. Active dispensing provides an immediate and intense air treatment whereas passive dispensing provides a continuous effect to the atmosphere over extended time periods at a slow release rate. Dual dispensers working on the active and passive mode have been described in the art.
• WO02/20172 published by Fresh Product on March 14, 2002 discloses a combined unit wherein the air freshener may be passively dispersed at a controlled rate or actively dispersed when a user pumps the apparatus to receive a measured quantity of hand lotion. Dispersion may be implemented using a mechanical fan or compression of a sponge.
• containers of cleaning products such as dishwashing detergent are left on countertops since they are in constant use through a day.
• Such containers can provide a dual purpose.
• an air freshener and a container for detergent, especially a hand dishwashing detergent, the air in the kitchen can be freshened to remove cooking or other odors or simply to add a pleasant fragrance to the air.
• WO2004/084954 published by Colgate Palmolive on October 7, 2004 describes a container for household product with, as a part of its structure, a passive delivery system for room freshening fragrance.
• a tray unit Associated with an upper portion of the container is a tray unit with a plurality of separate compartments containing the same of a different fragrance.
• Each compartment can be opened separately as a way to control the amount of delivery of the air freshener to a room.
• the fragrance emitting dispensing container described in WO2004/084660 published by Colgate Palmolive on October 7, 2004; is located in the closure.
• these prior art products provide only a continuous passive effect over a long time at a slow release rate.
• the present invention provides a combined detergent / air freshener dispenser which is able to provide in a highly simple and cost effective manner both an active burst of fragrance in the air and a passive dispensing of the same material by evaporation over an extended period of time in an environment where the detergent composition is stored and/or used.
• the consumer can obtain an immediate and intense air treatment, in addition to the continuous air freshening effect when the consumer dispenses the detergent for use or simply shakes the dispenser.
• the air freshening unit of the combined dispenser of the present invention is characterized by a fixed volume of above 45ml.
• the present invention relates to a combined dispensing container and air freshener [also referred hereinafter as "device”] comprising: (1) a container body comprising a detergent composition to be dispensed; (2) a container closure; and (3) an air freshening unit permanently attached to the container body and having a fixed volume of above 45 ml.
• the present invention also relates to a method to provide an immediate and intense air treatment by shaking said combined dispensing container and air freshener.
• an immediate and intense air treatment is obtained when the detergent is dispensed from the device.
• Figure 1 illustrates a front view of a combined dispensing container and air freshener.
• Figure 2 illustrates a perspective view of a combined dispensing container and air freshener.
• FIG. 1 depicts: A combined dispensing container and air freshener (1) comprises a container body (2), a flip-top cap as a closure (3) and an air freshening unit (4).
• the container body has a neck (5) and a grip area (6) preferably a squeeze area and a base (7).
• the air freshener unit (4) is attached to the base (7) of the container body (2) via for example groove(s).
• the air freshener (4) has a base (8) and a venting area (9). Such venting area is closed by a removable sticker (10).
• Figure 2 depicts the same combined dispensing container and air freshener (1) in a perspective view wherein the removable sticker on the venting area (9) has been removed.
• active dispensers shall be those which require an action on the part of the consumer to dispense a dispersible composition, which is dispersed as a burst or spray, as a direct result of the action of the consumer, while passive dispensers shall be those which require no action by the consumer at the time that the dispersible is dispensed, but dispense a dispersible by evaporation, sublimation, or the like, over a period of time, at a relatively low rate when compared to the rate of an active dispenser. Removal of a cover, wrapping, or control means from a passive dispenser is not to be considered an action to dispense the composition.
• a pourable detergent composition preferably a liquid detergent composition
• Such detergent composition is typically selected from the group of a dishwashing composition, a laundry composition, and/or a hard surface cleaning composition, and preferably is a hand dishwashing composition.

• Perfume loading of the particles can vary within broad ranges, depending on the particular demands for a particular device on the perfume composition and perfume carrier. Particles herein typically carry between 2%-75%, preferably 5%-60%, more preferably 5%-35% by weight of perfume, and the total weight of the particles may represent from 5 grams to 40 grams. In a preferred embodiment, the perfume loading of the perfume material and the amount of perfume material will be adjusted to match the longevity of the detergent composition when used at a regular dosage during a normal use by a normal consumer.

• the perfumes particles ideally should not impede air flow through the venting area. Particles stacked over the vent area have the effect of lowering the vent area. Preferably less than 50%, more preferably less than 25% of the vent area should be obstructed to provide the desired passive and active experience.
