PEEL AND REVEAL PERFUME LABEL ENCAPSULATION
The present invention relates to a device enabling to experience a
5 fragrance. More particularly, the invention is concerned with an
arrangement which enables to repeatedly transfer a fragrance contained
within a sealed enclosure to the skin of a person, whereby the fragrance
can be experienced, and the enclosure can be resealed for further
experiencing of the fragrance.
10 It is well known to provide a sample of a perfume or the like
when advertising this material, for example in a magazine. This may
take the form of a folding flap (scent strip) which covers the scent
present therein. This practice is standard with large circulation
magazines. However, this has all kinds of disadvantages, such as
15 evaporation of the solvent and scent present therein, with once opened
resulting into fragrance contamination. On the other hand, this scent
may not please everybody, which could damage the sale and circulation
of the magazine.
The prior art discloses cosmetic samples, pouch samplers and
20 fragrance release inserts. For example, Tararij et al (U.S. 4,952,400)
disclose a cosmetic sampler which includes a dry layer of powder
particles consisting of microcapsules which contain fragrance therein.
Light finger pressure ruptures the microcapsules to release the fragrance.
Obviously, this samples is not adapted per se to be used in a magazine,
25 for example. Since a surface, from which a fragrance sample can be
taken by breaking the microcapsules, it will obviously be realized that
such a samples could not be inserted into a high circulation periodical
without being damaged or destroyed and consequently it would be of no
practical use.

Charbonneau (U.S. 4,988,557) discloses a fragrance sampling
device used in magazines. A pull-apart sheet can provide immediate
fragrance release from a portion of the microcapsules by rupturing them
when the pull-apart sheet is pulled off. Other microcapsules, which are
5 not ruptured by the pull-apart sheet, can be ruptured later for a second
fragrance release by finger pressure. For obvious reasons, this device
could not be used as a sampler which remains in a magazine.
Giannavola (U.S. 5,248,537), describes an envelope containing a
fragrance that can be removed from a magazine to sample the fragrance.
10 This prevents the fragrance from contaminating the magazine.
However, this magazine insert is not reusable and has to be removed for
testing, which is a clear disadvantage.
Bootman et al in U.S. 5,391,420 disclose a pouch formed of two
film members between which a polymer gel containing fragrance has
15 been placed. The fragrance is revealed by separating the two film
members. Again, this is not a reusable device, and no means are
provided to transfer the fragrance to the skin of a person.
Charbonneau, in U.S. Patent No. 5,419,958, describes a fragrance
sampler wherein a microencapsulated liquid fragrance is disposed in a
20 cavity which is broken off to release the fragrance. This device is not
reusable.
Whitaker, in U.S. Patent No. 5,645,161, describes a packet
sampler wherein the aim is to prevent a premature release of odors. This
device which is not reusable cannot be used to repeatedly transfer a
25 fragrance to the skin.
It is therefore an object of the present invention to provide a
device which enables to experience a fragrance a plurality of times.
It is another object of the invention to provide a fragrance testing
device for insertion into a magazine or the like and wherein the
30 fragrance can be repeatedly experienced.

It is another object of the invention to provide a system adapted
to produce a device according to the invention.
In accordance with the invention, there is provided a device
enabling to repeatedly transfer fragrance from a sealed enclosure
5 containing the fragrance, to the skin of a person, whereby the fragrance
can be experienced a number of times, wherein the device comprises
a flexible base,
an adhesive material at least partly of repositionable type
disposed on the flexible base as a layer forming a closed continuous
10 band defining a fragrance enclosure within inner boundaries thereof,
fragrance capsules placed in the enclosure and suitable for
transfer from the enclosure to the skin of a person, and
a resealable sheet of flexible material placed over the closed
continuous band of adhesive to sealingly cover the enclosure and
15 capable of being unsealed and resealed whenever the fragrance is
intended to be experienced.
In accordance with a preferred embodiment, the flexible base is
fixed to a flexible support by means of a permanent or repositionable hot
melt water based adhesive, which may have high shear strength and
20 good initial tack.
The flexible base preferably comprises a one side litho paper.
In accordance with another preferred embodiment, the adhesive
material defining the continuous band has a portion consisting of
permanent water based adhesive thereby preventing the resealable sheet
25 from being completely removed when unsealing the enclosure, the
remaining portion comprising a repositionable water based adhesive.
To be more efficient, the device according to the invention is
provided with an oxygen barrier coating on the sheet of resealable
flexible material, preferably on the upper face thereof.

FIGURE 3 is a schematic view in elevation of a satellite press
which can be used to produce a device according to the invention.
Referring to the drawings, more particularly FIGURES 1 and 2, it
will be seen that the device which is illustrated is adapted to be mounted
5 on a paper support 1 which in the illustrated embodiment consists of a
40 or 50 lbs. siliconized carrying liner semi-bleached, super calendered
Kraft. Of course, any other suitable material could be used as will be
appreciated by one skilled in the art, such as for example, it could
consist of a 44 PK on clear polyliner. A base 3 for the device, here
10 rectangular and preferably made of 37 to 60 lbs. coated one side litho
paper with a range of 1 to 6% elongation MD/CD, is fixed to paper
support 1 by means of a permanent hot melt water based adhesive 5
having high shear strength and good initial tack. Of course, it is
understood that other adhesives could be used, such as a repositionable
15 adhesive, and the choice will be left entirely to one skilled in the art.
In
the same manner, base 3 could consist of other suitable materials, the
particular choice being left to the skilled person, depending on
circumstances.
With particular reference to FIGURE 2, it will be seen that a
20 layer of repositionable water base adhesive 7, preferably one which has
been designed for flexographic or letterpress transferability, has been
applied on the upper face of base 3 in the shape of a closed continuous
rectangular frame like band 9 as shown more particularly in FIGURE 2.
In the embodiment which is particularly illustrated in FIGURE 2, it will
25 be noted that the three outer sides 11, 13, 15 of the rectangular band 9
are aligned flush with the outer edges 17, 19, 21 of base 3, while the
fourth side 23, as shown, is slightly retracted from edge 25 of base 3. In
the space provided between the fourth side 23 and edge 25 of base 3,
there is provided a layer of permanent water base adhesive to define a
CA 02285854 1999-10-13
6
strip 27, preferably of the type designed for flexographic and letterpress
equipment.
Within free space 29, defined by rectangular frame like band 9,
there is provided a water base capsulation perfume dry powder 31 which
5 is transferable to the skin. This powder has been obtained by drying a
water base slurry of a mixture of an inert capsulation powder with
fragrance substance.
Finally, dry powder 31 is sealed by means of a rectangular sheet
33 of a litho paper, here a 40 to 60 lbs. two side coated litho paper grade
10 #2. Of course, any other suitable sheet of flexible material could be
used, the choice being left entirely to one skilled in the art. For example
a polypro or polystyrene from '/2 mil to 2.5 mil could be used. Sheet 33
should be capable of receiving printed material 35 (FIGURE 1), such as
designs and instructions. On top of the flexible rectangular sheet 33,
15 there is a layer 37 (FIGURE 1) of an oxygen barrier UV siliconized
lacquer which is of a type well known to those skilled in the art This
will of course prevent the fragrance from deteriorating while being
stored in the device according to the invention.
It will be realized that because of repositionable adhesive band 9
20 and permanent adhesive strip 27, flexible sheet 33 may be resealed and
unsealed any number of times without being completely removed from
the assembly, as particularly shown in FIGURE 2. This operation will
last as long as some fragrance capsulation powder 31 remain within
space 29 provided inside rectangular band 9.
25 To provide for an easier lifting up of sheet 33 for unsealing the
device, the corners of base 3 opposite the end provided with strip 27 of
permanent adhesive, are free of repositionable adhesive to define
respective dry laps 39,41 as shown.
So, for testing the particular fragrance contained within a sample
30 device according to the invention, it is merely necessary to lift up
CA 02285854 1999-10-13
7
flexible sheet 33 at one or both corners provided with dry laps 39,41 to
reveal capsulation fragrance dry powder 31. Then, by the touch of a
finger some dry fragrance powder can easily be transferred to the skin of
a person to experience the fragrance. The flexible sheet is thereafter
5 resealed over base 3 against band 9 of repositionable adhesive. It will
also be noted that lacquer layer 37 prevents any unwanted evaporation
or loss of fragrance when the device is sealed.
The device according to the invention can be manufactured by a
multiplicity of processes which could easily be designed by one skilled
10 in the art. An advantageous way however is obtained by means of the
satellite press which is schematically illustrated in FIGURE 3 of the
drawings.
The press mainly consists of top unwinder unit 43, bottom
unwinder unit 45, printing stations 47, 49, 51, 53, 55, 57, 59, 61, 63 and
15 65, die-cut stations 67, 69,71,73, matrix removers 75, 77, 79, and
rewinder unit 81. Top unwinder unit 43 contains a roll of 40 to 60 lbs.
two sides coated litho paper 33 which is carried through printing stations
49, S 1, 53, 57, 59, 61 for printing and depositing a layer of oxygen
barrier UV lacquer. Bottom unwinder unit 45 contains a roll of pressure
20 sensitive material 3, that is carried through printing stations 47, 61, 63,
65. At printing station 47, the pressure sensitive material 3 will receive
instructions on how to use the dry powder transferable capsules 31,
which will be deposited in predetermined quantity at station 61. At
station 63, there is an application of permanent adhesive to form strip
25 27, and at station 65, the rectangular band 9 of removable adhesive will
be formed. Any printing and/or design application 35 is carried out by
means of turn bar systems 83 which enables to print recto/verso, if
needed. All along the printing stations, drying units 85 are provided to
enable to dry the inks applied at 83 with a combination of cold air, hot
30 air using infrared light and ultra violet light, which combination is well
CA 02285854 1999-10-13

known to those skilled in the art. The water based capsulation slurry 31
is transferred to litho paper base 3 at printing station 61 as a rectangular
coating thereof as better illustrated in FIGURE 2. A water based
permanent adhesive is applied in the form of strip 27 (FIGURE 2) at
5 printing station 63, while a water based repositionable adhesive is
applied against base 3 in the form of a rectangular frame like band 9 at
printing station 65. Litho paper 31 and litho paper 3 are then laminated
in laminating unit 84 which combines a predesigned engraved transfer
roll (not shown). From there, the laminate passes through die-cut
10 stations 67, 69, 71, 73 which are designed to die-cut the full construction
in various shapes and sizes as will be appreciated by one skilled in the
art. Associated with the die-cut stations there are three air assist matrix
removers 75,77,79 which are used to remove the matrix from the full
construction liner. Only die-cut station 73 could be used to produce a
15 device with predetermined shape and design, if it is found preferable to
do so.
Finally, the construction on which the device according to the
invention appears is sent to rewinder unit 81 with predetermined digital
tension control.
20 It is understood that modifications are possible without departing
from the spirit and scope of the present invention, as defined in the
appended claims.
