Description
FIELD OF THE INVENTION
[0001] The present invention relates to innovative packaged
products wherein the package is able to release fragranced air in
response to an action from a user e.g. when a consumer picks up
said packaged product in a store, without the need to open the
package and expose the product to the air.
BACKGROUND OF THE INVENTION
[0002] Modern studies on consumer behaviour show that consumers
give more and more importance, when selecting which product to buy,
to a pleasant shopping experience which involves all senses.
Stores, shelves, product packages and labels are all designed in
order to provide the consumer not only with information on the
product contained in the package, but also to provide a pleasant
experience to the consumer touching and handling the product before
purchase.
[0003] Smell is one of the key elements providing this experience,
for example in many cases consumers want to test the smell of a
product before purchasing it so they tend to open packages and
bottles to perform this trial. On the other hand product
manufacturers tend to seal the products to avoid product
contamination, dispersion or alteration, thus inhibiting consumers
to make this test. It is therefore important to be able to provide
consumers with a way to test the smell of a sealed product before
actually purchasing it, without having to break the seal or open
the package.
[0004] In other cases product manufacturers may want to expose
consumers to a smell which is not the smell of the product (e.g. if
the product has no smell), but is instead a perfume or a fragrance
that the product manufacturers consider part of the experience the
consumer has to make when handling that product.
[0005] Conventional systems to integrate a perfume releasing
material in a package commonly involve the use of perfumed stickers
or labels typically applied to the external surface of the package
where the perfume is encapsulated and the consumer is directed to
peel off or to scratch the label.
[0006] These systems however suffer severe limitations e.g. peel
labels cannot be reused once peeled off, so that the item with the
label peeled off is perceived by the consumer as a damaged item and
is often refused by the consumer. Similarly, scratch and sniff
labels tend to wear out and to lose effectiveness after some uses
thus losing functionality and appeal for the consumer.
[0007] JP06001332 by Sanra K K, attempts to solve this problem by
suggesting a container wherein at least a part of the external
surface in contact with the air is provided with a polymeric
material comprising a perfume. This solution has still many
disadvantages in fact the container when exposed in a store will
continuously release the perfume in the environment mixing it with
the perfume released by other products employing the same
technology. Additionally this continuous and unnecessary release of
perfume will lead to perfume depletion in short time. Moreover
retailers and consumers would refuse to have in the shop or at home
several containers each continuously releasing their own perfume
and mixing up in the air.
[0008] There is therefore a need for new systems to provide a scent
to consumers handling a packaged product which are activated by the
consumer.

DETAILED DESCRIPTION OF THE INVENTION
[0026] The present invention encompasses an article of manufacture
comprising a product in a package. For package it is intended any
physical barrier separating said product from the external
environment including for example a bottle, a can, a film wrap, a
case, a tube (e.g. for toothpaste, glue, sauce), a box, and the
like. Said package is preferably a sealed package i.e. a package
which completely isolates said product from the external
environment and which is intended to remain sealed until the
product is purchased by a consumer. For product it is intended any
article which can be commercialized to final consumers, e.g. in a
supermarket, such as, for example, but not limiting to, household
detergent, personal detergent, personal care products, cosmetics,
hygiene articles, food products, household goods, furniture,
outdoor goods, apparel goods and the like.
[0027] In a first embodiment said article of manufacture further
comprises an enclosure formed outside of said package and between
said package and a second surface. For enclosure it is meant a
delimited space whose boundaries are defined by the external
surface of said package and a second surface as defined below. Said
enclosure is in general "closed" in the sense that there is no
substantial exchange of air from inside the enclosure to the
outside in absence of a specific action from the user. In some
embodiments of the present invention the enclosure is tightly
closed (e.g. a cap over the seal of a sealed bottle) in other
embodiments said enclosure will comprise at least one small opening
through which the air contained in the enclosure can be expelled
only in response to an action from a user such as pushing or
squeezing at least a portion of the article.
[0028] Said second surface can be any surface which delimits the
enclosure together with a portion of the external surface of said
package.
[0029] Example of second surfaces are e.g. the internal surface of
a cap or a lid over the seal of a sealed bottle, of a secondary
package which partially or entirely encases said package (a carton
box, a thermoformed blister pack and the like), or a re-attachable
label closing a concave portion of said package surface.
[0030] Said enclosure comprises a headspace. The headspace is
defined herein as the volume of air comprised in said enclosure.
Said enclosure also comprises a perfume releasing material. The
perfume is released in the enclosure creating an equilibrium state
wherein the air in the enclosure headspace is saturated with
perfume. Once equilibrium is reached, due to the low or minimal
exchange of air from within the enclosure to the external
environment, the perfume releasing material stops releasing the
perfume.
[0031] The articles of the present invention also comprise means
for releasing said perfume in said headspace to the external
environment and to regenerate said headspace collecting air from
the external environment. Said means are preferably activatable by
a consumer handling the article in a store typically before
purchase.
[0032] Any means capable to achieve the intended result of
releasing the perfumed air from the headspace to the external
environment and then regenerating the headspace is suitable in the
articles of the present invention. Some non limiting examples of
these means include a lid or a cap over a the seal of a sealed
bottle or container, a thermoformed blister pack completely
encasing the packaged product comprising at least one small hole or
aperture, a carton box in which the packaged product is closed
(e.g. a carton box enclosing a toothpaste tube), a flexible package
surrounding the packaged product comprising at least a small hole
or aperture and the like.
[0033] For the purpose of clarity, preferred configurations within
said first embodiment can be collected in two main groups:
[0034] In a first group the packaged product is in a sealed
package, said sealed package comprising a cap or a lid, which do
not contribute to sealing said product, said cap or lid defining
the enclosure comprising the headspace to be saturated with the
perfume. The perfume releasing material is applied in the so
defined enclosure, for example onto the external surface of the
package or, more preferably, on the internal surface of the cap or
lid. A consumer in a store can remove the cap or lift the lid
without unsealing the packaged product thus causing the release of
the perfumed air in the headspace. When the cap or the lid is
closed again, a fresh headspace is regenerated. The perfume
releasing material will start releasing perfume in the headspace
until equilibrium is reached so that the headspace is regenerated,
ready to release a new perfume bloom upon a subsequent opening of
the cap or lid.
[0035] A second group of preferred configurations are those
activatable by pushing or squeezing the article of manufacture of
the present invention. This group includes all cases wherein a
secondary package completely encases the packaged product. Said
headspace is formed between the external surface of the packaged
product and the internal surface of the secondary package, which
corresponds to said second surface, and the perfume releasing
material is preferably applied onto at least one of said packaged
product external surface or secondary package internal surface. Any
material commonly used for packaging purposes can be used to
manufacture said secondary package, for example, but non limited to
carton, plastic, wood, plastic films, metal films, composite
materials, carton/plastic, or carton/metal film laminates and the
like. Said secondary package is not sealed and preferably flexible.
Means for releasing the perfume from the headspace to the external
environment, and also for regenerating the headspace collecting air
from the external environment may comprise a re-closable opening in
said secondary package, wherein the user can open the secondary
package and be exposed to the perfume, but without exposing the
product to the external environment, and then re-close it thus
regenerating the headspace. More preferably said secondary package
comprises at least one small hole or aperture such that there is no
substantial exchange of air from inside the enclosure to the
external environment. Preferably the surface area, measured along
the surface of said secondary package, of said at least one hole or
aperture is less than 30 mm.sup.2, more preferably less than 10
mm.sup.2 even more preferably less than 5 mm.sup.2, most preferably
less than 2 mm.sup.2. A consumer squeezing the article will cause a
part of the perfumed air in the headspace to be released, while the
elasticity of the container will return it to its original shape
upon release of said pressure by the consumer thus regenerating
said headspace.
[0036] A less preferred configuration in this family includes a
blister or a small vented button applied onto the surface of the
packaged article e.g. on the side surface or on the top of the cap.
Perfume releasing material is contained within said blister. The
small button or blister can be made of compressible plastic and has
at least a hole or aperture to release the perfumed air in the
headspace. Preferably the surface area, measured along the surface
of said button or blister, of said at least one hole or aperture is
less than 30 mm.sup.2 more preferably less than 10 mm.sup.2 even
more preferably less than 5 mm.sup.2, most preferably less than 2
mm.sup.2. This embodiment is less preferred because said second
surface requires the use of a further material only devoted to
create said second surface. It is in general preferred that said
second surface has another function other than that of defining
said enclosure such as e.g. being the internal surface of a cap or
of a secondary package.
[0037] In a second embodiment the articles of manufacture of the
present invention comprise a packaged product wherein said package
further comprises a package base. "Package base" is intended as a
portion of the surface on which said article is able to stand when
placed on a substantially flat surface.
[0038] Said package base further comprises a concave portion. Said
concave portion is able to cooperate with a second surface to form
an enclosure. Preferably said package base comprises a series of
coplanar points forming a closed perimeter in which said concave
portion is comprised so that when the article of the present
invention is placed onto a flat surface said coplanar points
cooperate with said flat surface forming an enclosure. A preferred
example of this embodiment is a typical aerosol can which has a
concave base with a circular profile. Said circular profile is
commonly made of coplanar points so that, when the can is placed
onto a flat surface, said circular profile forms the enclosure
between said concave base and said flat surface. Although not
preferred, other configurations can be envisioned by those skilled
in the art, for example the package could have a not planar profile
which cooperates forming a joint with a correspondingly formed slot
onto a surface thus forming the enclosure. An example of this
embodiment is an aerosol can having a wavy base instead of the
usual circular base which can be placed on a rack having
corresponding slots.
[0039] Said concave portion comprises a perfume releasing material,
preferably applied onto at least a portion of the surface of said
concave portion.
[0040] When an article of the present invention is placed onto said
surface forming an enclosure, said enclosure comprises a headspace
(i.e. a volume of air comprised in said enclosure), perfume is
released in the enclosure creating an equilibrium state wherein air
in the enclosure headspace is saturated with perfume. Once
equilibrium is reached, due to the low or minimal exchange of air
from within the enclosure to the external environment, the perfume
releasing material stops releasing the perfume.
[0041] When a consumer lifts said article from the surface on which
it is placed, the perfumed air comprised in the enclosure is
released to the external environment and the consumer perceives the
perfume. When the consumer places the article back on said second
surface the headspace is regenerated for next perfume bloom.
[0042] In all embodiments, artwork on the article may be used to
communicate the scent to the consumer, e.g. a picture of a lemon
with lemon scent being delivered from a separate perfume release
material.
[0043] According to the present invention, the perfumed headspace
within the enclosure is always kept isolated from the product,
hence avoiding any contamination between the perfume releasing
material and the product. The present invention has the further
advantage that, at the same time, the perfume releasing material is
made available to a consumer, i.e. released in the environment,
only upon direct activation from the consumer, while being normally
isolated from the environment.
[0044] Perfume releasing materials for use in the present invention
can be provided in any suitable form. In some embodiments, the
scent releasing material comprises perfumes, such as perfume oils,
that are incorporated onto or into a suitable carrier. Any perfume
can be used in the present invention. The carriers can be provided
in the following non-limiting forms: a solid, a gel, beads,
encapsulates, wicks, a carrier material, such as a porous material
impregnated with or containing the scent, and combinations thereof.
A foam or sponge material impregnated or containing the perfume can
be used as a carrier and is particularly suitable for those
embodiments of the present invention which are activated by pushing
or squeezing the article of manufacture as described above. In some
embodiments the carrier is in the form of a gel which together with
the perfume forms a gel composition. Two non-limiting examples of
gels that can be used are hydroxypropyl cellulose and fumed silica.
The perfumes are often formulated into a gel composition. to reduce
the partitioning effect (i.e. the effect which causes that the more
volatile components of a perfume tend to evaporate more than the
less volatile components thus leading to a change in perfume
character with time) that occurs when a perfume evaporates. The
amounts of perfume and gel in the gel composition can vary
depending on the particular perfume and the gel. In certain non
limiting embodiments, the gel composition is about 90% perfume and
about 10% hydroxypropyl cellulose or about 93% perfume and about 7%
fumed silica, although other ratios are clearly contemplated. There
are a variety of hydroxypropyl cellulose/silica ratios that may be
used in combination in the gel composition as well as other
appropriate gelling agents.
[0045] Particularly preferred perfume carriers for use in the
present invention comprise polymeric materials in which perfumes
are solubilized. In general these materials are able to absorb and
gradually release large amounts of perfumes for very long times. In
addition the partitioning effect is further reduced with respect to
gels.
[0046] Any polymeric material capable to solubilize and gradually
release a perfume can be used as a perfume carrier in the present
invention. Polymeric materials which can be used for this purpose
are those comprising e.g. PVC polymers, polyurethane polymers and
co-polymers, polysaccharide polymers and co-polymer,
polyoxyalkylene polymers and co-polymers, co-polymers formed by a
monomer comprising an ether group and a monomer non comprising an
ether group, copolymer of ethylene with at least another monomer
comprising at least a heteroatom. Particularly preferred polymeric
materials are those comprising polyether-amide co-polymers,
polyether-ester copolymers, polyurethanes, ethylene vinyl acetate
co-polymers, polytetramethylene glycol. Even more preferred are
those comprising ethylene vinyl acetate co-polymers.
[0047] Particularly preferred perfume carriers are polymeric
compositions which, in addition to one or more polymers as
described above also comprise one or more plasticizers.
Plasticizers reduce the melting point of the material, thus
allowing to incorporate perfumes at lower temperatures thus
minimizing perfume loss e.g. when the perfume releasing material is
applied in the molten state to the desired substrate. Plasticizers
also reduce the viscosity of the melt, thus allowing to handle the
perfume releasing material as a hot melt glue typically in standard
hot melt coating apparatuses in a manufacturing line thus
significantly simplifying the manufacturing process of any article
comprising such perfume releasing materials. Moreover the skilled
man, by choosing the appropriate plasticizer or mixture of
plasticizers among those which are suitable for a certain polymeric
matrix, can modify the polarity of the polymeric matrix in order to
match the polarity of the perfume thus allowing to incorporate a
larger amount of perfume and a broader variety of perfume
ingredients.
[0048] Suitable plasticizers for use in the polymeric compositions
according to the present invention include citric acid esters, low
molecular weight polyesters, polyethers, liquid rosin esters,
aromatic sulphonamides, phthalates, benzoates, sucrose esters,
derivatives of polyfunctional alcohols (where "polyfunctional"
means having 2 or more hydroxyl groups), adipates, tartrates,
sebacates, esters of phosphoric acid, fatty acids and diacids,
fatty alcohols and diols, epoxidised vegetable oils etc, and
mixtures thereof. The different polarity of the different
compatible plasticizers (measurable with any method known to those
skilled in the art, for example water/octanol partition
coefficient) can be used to tune the polarity of the polymeric
matrix in order to provide a better match with the polarity of the
perfume.
[0049] Preferred polymeric compositions comprising polymers,
plasticizers and perfumes as mentioned above are described in
co-pending European Patent Applications number 03026234.9 filed on
Nov. 14, 2003, 04013513.9 filed on Jun. 8, 2004, 04018573.8 filed

(Switzerland) were added to a sigma blade mixer and heated to a
temperature of about 10-20.degree. C. above the melting point of
the polymer (about 120.degree. C.). The ingredients were mixed
until a homogeneous mass was obtained. The temperature was then
reduced to a point where the mixture was still molten, typically to
about 10-20.degree. C. above the melting point of the mixture
(about 80.degree. C. in the present case). 50 parts of benzyl
acetate, a perfume material available from Sigma Aldrich, were
added to the plasticised polymer mixture. The ingredients were
mixed until a homogeneous mixture was obtained, and the resultant
material removed from the mixer, cooled to room temperature is used
as a perfume releasing material to be applied as a hot melt
adhesive.
