Definitions

• the present invention relates to a package or container for an odorant composition, particularly but not exclusively for laundry and cleaning compositions.
• Odorant additives e.g. perfume, fragrance components are therefore an important aspect of the successful formulation of such commercial products .
• fragranced products with sealed packaging to protect the prevent or at least reduce premature and unintended release of volatile odorant components so that pre-purchase odorant testing may not possible or optimum.
• packages may be damaged by consumers attempting to smell the product before purchase which is undesirable.
• Odorant testing devices such as fragranced test strips or so-called “scratch and sniff” device, can be attached externally to the packaging to allow consumers to test the product however, these normally increase the pack costs, the complexity of manufacture and the amount of packaging material, which are undesirable.
• the invention provides a package containing an odorant composition, characterised in that the package comprises a first outlet which is initially closed for opening after purchase to allow controlled egress of the composition for use in a laundry process and a further olfactory outlet facilitating release of odorant components from the composition to provide multiple consumers with means for repeated olfactory testing of the composition before purchase but preventing or at least minimising egress of non-volatile components of the composition, said packaging comprising a olfactory outlet closure positionable between an open position allowing said olfactory testing and a closed position which prevents or at least minimises release of odorant components between testing events.
• the olfactory components being tested are provided by the composition there is no complicated testing device necessary.
• the invention offers a remarkably simple solution to a long standing problem. Instructions for use of the olfactory closure device may be included.
• the invention provides a method of pre- purchase olfactory testing by multiple consumers of odorant compositions in packages, wherein each package containing an odorant composition is according to the first aspect of the invention, and wherein at least two different compositions are provided in respective separate packages so that the consumers may select a preferred composition, the method comprising the steps of:
• the olfactory outlet may comprise one or more micro-holes.
• the micro-holes may be of any suitable shape or size and may be uniform or vary in this respect .
• One or more the micro- holes may present in a visual or tactile aesthetic pattern, image or message/instructions to the consumer.
• the or each micro-hole has a diameter from 0.1 to lmm.
• Packaging for free flowing material having particles which are small may benefit from a greater number of micro- holes at the lower end of the range to reduce any risk of fine particles escaping via the micro-holes.
• the olfactory outlet is preferably located at an upper part of the pack (when orientated upright on a base) .
• the olfactory outlet closure may comprise flexible sheet material and may comprise a layer of adhesive which can releasably adhere to the pack to cover the olfactory outlet between testing events.
• exemplary flexible sheet materials include mono-layer, co-extruded or laminated films. Such films may comprise various components, such as polyethylene, poly-propylene, polystyrene, poly-ethylene- terephtal ate.
• the olfactory outlet closure may also be paper, or metal/metalised material.
• the closure comprises a poly-ethylene and bi- orientedpoly-propylene co-extruded film.
• the sheet material may have various thicknesses. The thickness should typically be between 10 and 150 ⁇ m, preferably between 15 and 120 ⁇ m, more preferably between 20 and 100 ⁇ m, even more preferably between 25 and 80 ⁇ n and most preferably between 30 and 40 ⁇ m.
• the olfactory outlet closure may also be positionable so that only part of the outlet is opened e.g. to allow only some of the micro-holes are opened. In this way it is positionable part way between said open and closed positions to vary to amount of odorant released. This has the advantage that consumers can select the odorant release level in response to their personal preference .
• the package may comprise any suitable material e.g. paperboard, corrugated cardboard or plastic or combinations thereof .
• the package may have any suitable construction e.g. a bag, pouch, carton, box or the like.
• the package of the invention preferably consists of a consumer unit containing the detergent composition of the invention and designed to be used/stored as such in the consumer homes .
• Packages can be made from sheet material, and can be sealed by various means, e.g. by heat, adhesives/glue, tapes.
• Films may be either monolayer, including coextruded materials, or laminated; such films are typically paper or plastic or combinations of ' the two. Paper board may be used for cartons and this may include plastic layers for e.g. barrier and/or releasable sealing of olfactory outlet closure as mentioned above.
• Suitable materials for the bags herein are plastic and/or paper laminates. Plastic materials are typically polyolefines, and both plastic and paper can be virgin or recycled material; the films herein can be printed in different ways, typically gravure, flexo, offset. Also encompassed herein are films with moisture barrier properties, obtained by resins, either coextruded or in different laminated layers, or coating by e.g. lacquers.
