WO 03/037768 PCT/US02/34258
In one specific embodiment, an adhesive component comprises a flexible plastic
film, a first adhesive and a second adhesive. According to a further
embodiment, the first
adhesive is adapted for adhering under a first specific condition, and the
second adhesive
is adapted for adhering under a second specific condition. In one exemplary
embodiment,
for instance, the first adhesive is adapted for adhering under a hot condition
and the
second adhesive is adapted for adhering under a cold condition. In another
exemplary
embodiment, the first adhesive is adapted for adhering under a moist condition
and the
second adhesive is adapted for adhering under a dry condition. In yet another
exemplary
embodiment, the first adhesive is aqueous based and adapted for adhering under
conditions wherein an aqueous based adhesive is effective, while the second
adhesive is
oil based and adapted for adhering under conditions wherein an oil-based
adhesive is
effective. According to the present embodiments, the first adhesive and the
second
adhesive may be provided in a single composition, for example to form a
heterogeneous
mixture. As used herein, "single composition" is intended to encompass any
combination
of necessary parts or elements which together provide a whole substance and
which may
exist in a form such as, but not limited to, a mixture, a layering of
components, an
intermixing of ingredients and the like. Alternatively, the first adhesive and
the second
adhesive may be packaged apart from one another. Additionally, it is
envisioned that
color coding of the first adhesive and the second adhesive may be desired when
more
than one adhesive component is utilized according to the present invention.
For instance,
it may be desirable to individually assign the first and second adhesive
component, andlor
their respective packages, a specific color designation which the user cam
identify prior to
using such component. According to this embodiment, the user will be able to
easily
identify which given adhesive is appropriate for the specific adhering
activity by
matching the color of the component and/or package with a predetermined color
coding
instruction guide or other similar identification device.
In one embodiment, the adhesive component is adapted to provide the flexible
plastic film with a semi-permanent adherence and/or bond to a surface. In this
embodiment, the adhesive component is adapted to adhere the flexible plastic
film to, for
example, a glass surface such as the rim of a glass bowl, with a bond
sufficiently strong to
resist unsealing of the flexible plastic film and to prevent the contents of
the bowl from
7

CA 02460265 2004-03-15
WO 03/037768 PCT/US02/34258
breaking the adherence if the bowl is tipped or overturned, yet sufficiently
weak to allow
removal of the flexible plastic film from the surface by firm pulling by the
consumer
when so desired. More particularly, the flexible plastic films of the present
invention are
designed to exhibit an adhesion property sufficient to survive the likely
degree of
handling the adhered article or enclosed container is lilcely to encounter in
use while
maintaining the desired level of adherence with the item, with itself, or with
the
accompanying semi-permanently enclosed container such that preservation or
storage of
the targeted item is ensured.
~ne way to measure or quantify this adhesion property is in terms of an
adhesion
peel force value which is preferably measured by Pressure Sensitive Tape
Council
Method PSTC-1. According to this method, a 12-inch (30.5 cm) by 1-inch (2.5
cm) strip
of film is rolled once against a smooth stainless steel surface at a rate of
12 inches (30.5
cm) per minute using a 4.5 pound (2.04 kg) roller and then tested as having a
peak
adhesion peel force value ranging from about 1 to about 50 ounces/inch (0.012
to 0.600
kg/cm), more preferably from about 1 to about 2.5 ounces/inch (0.012 to 0.027
lcg/cm) of
strip width. In general, minimum adhesion which maintains an adherence is
desired for a
flexible plastic wrap, so that the wrap is easily peeled open for access to
the stored
item(s).
In one embodiment, at least one of the flexible plastic film and the adhesive
component comprises a colorant adapted to provide a visible color expression
upon
adhering the flexible plastic filin to an article. As used herein, "colorant"
generally refers
to a substance that colors or modifies the hue of another substance. According
to this
embodiment, a color expression is provided by the adhesive component once the
flexible
plastic film is adhered to an article thereby confirming to the user whether a
sufficient
adherence has been established. Moreover, in further embodiments, the flexible
plastic
film and the adhesive component may each individually comprise a color
component
which together are adapted to provide a color expression upon adhering the
flexible
plastic wrap to an article.
In another embodiment, the adhesive component comprises an encapsulated
pigment adapted to provide a visible color expression upon application of
pressure to the
adhesive component. As used herein, "encapsulated pigment" generally refers to
an
8

CA 02460265 2004-03-15
WO 03/037768 PCT/US02/34258
encased or enclosed substance of color. More particularly, it is envisioned
that upon
applying pressure to the adhesive component, the casing or enclosure is
ruptured or
otherwise altered and a visible color expression will be provided thereby
confirming the
sufficiency of the adherence between the article and the flexible plastic
filin. After such
application, the user can visually identify which portions, if any, of the
resultant
adherence are lacking sufficient bondage by comparing the areas exemplifying a
positive
color expression to the areas lacking such a color expression. As used herein,
"application of pressure" refers generally to the exertion of force to the
desired material.
Depending on the desired use, the adhesive components of the present invention
may be dispensed from a variety of devices. These devices include, but are not
limited to,
sticks, tubes, spray devices, bottles, pens, brushes, sponges and combinations
thereof.
In another embodiment, the plastic wrap kits further comprise instructions for
use
of the kit, for example, for achieving an adherence between the flexible
plastic film and
an article. The instructions may comprise written instructions and/or one or
more
illustrated nonverbal cues. As used herein, "nonverbal cue" generally refers
to a
communication signal without the use of vocabulary. Furthermore, it should be
understood that the instructions are not limited to uses associated with
adhering the
flexible plastic film and the article. Alternatively, the instructions may
provide optional
uses for the plastic film and/or the adhesive component in other embodiments.
It should
be understood that use of the plastic wrap kits disclosed herein are not
limited to any one
application. For instance, an adhesive component may be applied to only a
portion of an
article desired to be covered. Alternatively, a complete application of
adhesive may be
necessary. In still other embodiments, the application of an adhesive
component may be
unnecessary altogether. As a result, it should be understood that the plastic
wrap kits
according to the present invention are intended to be flexible in their nature
of
application, wherein the individual user will decide the exact method of
application
necessary for each given situation.
hl one specific embodiment, the plastic wrap kit comprises (a) a flexible
plastic
film arranged on a roll; (b) a food safe adhesive component provided in stick
form; and
(c) instructions for use of the kit. This embodiment provides for consumer
convenience.
In those embodiments wherein the adhesive component and the flexible plastic
film are
9

CA 02460265 2004-03-15
WO 03/037768 PCT/US02/34258
prepaclcaged together, the packaging can be of any conventional arrangement.
For
instance, the adhesive component could be independently placed within the
container
housing the flexible plastic film. Similarly, the adhesive component could be
located
within the core of a roll type product or placed within any other void space
surrounding or
witlun the roll. For instance, the flexible plastic film and adhesive
component can be
packaged together in a kit such as depicted by Figs. 1 and 2. In accordance
with these
embodiments, a container 10 made of any suitable packaging material, for
example
cardboard, includes a roll 15 wrapped with a flexible plastic film 40 (not
shown in Fig. 1).
A core 35 of the roll 15 is adapted to house a stick 20 of an adhesive
component. The
stick 20 is arranged within the core 35 by a holding piece 25. The container
10 may
optionally be provided with instructions 30 to explain the use of the
components.
Furthermore, as depicted in Fig. 2, the adhesive component stick 20, together
with the
holding piece 25, may be easily inserted into and removed from the core 35 of
the roll 15.
One skilled in the art, however, will appreciate that other arrangements of
the
plastic wrap kit in accordance with the present invention may be formulated,
as Figs. 1
and 2 are not intended to be limiting thereof. For instance, the adhesive
component may
be attached to the outside of a container housing the flexible plastic film
or, alternatively,
independently packaged altogether. Additionally, the individual components of
the
plastic wrap lcits according to the present invention may also exist in a
variety of product
forms. For instance, in one exemplary embodiment, the adhesive component is in
the
form of a ribbon or chain-like structure which may be stored or located within
the core of
the plastic wrap roll. The ribbon or chain may, for example, comprise a
plurality of
individually packaged adhesive portions. In yet another embodiment, a
heterogeneous
adhesive bar, or an adhesive bar comprising one or more adhesive strips, is
located within
the plastic wrap kit in a position such that removal of the flexible plastic
film causes the
film to be coated with the adhesive component. In further embodiments, a
reservoir of an
adhesive component, or a mixture of one or more adhesive components, is
provided and
may, for example, be located within the lid of the kit such that the adhesive
component is
sprayed upon the desired surface of the flexible plastic film upon dispensing.
As a 'result,
the physical arrangement, as well as the product form of the components,
namely the

CA 02460265 2004-03-15
WO 03/037768 PCT/US02/34258
flexible plastic filin, adhesive component and optionally instructions,
according to the
invention, can exist in any arrangement within the kit.
hl still other embodiments, the food wrap lcit comprises a flexible food wrap
material arranged on a roll, a container housing the flexible food wrap
material, and an
adhesive component located on a surface of the container. For instance, in one
specific
embodiment, the adhesive component may be located under a removable opening
tab
located on the surface of the container. Upon a user removing the opening tab
during the
initial opening of the container, the adhesive component will be exposed and
thereby
available for application onto flexible food wrap materials. According to this
embodiment, the user may drape the flexible food wrap material over the
adhesive
component and subsequently apply pressure (such as with the user's finger) to
the wrap
material such that the material comes into contact with the adhesive component
and is
coated with such adhesive.
In similar embodiments, it is envisioned that one or more adhesive component
may be positioned at various locations upon the surface of the container such
that during
the dispensing of the flexible food wrap material, the one or more adhesive
component is
applied to predetermined and specifically targeted locations of the wrap
material. For
instance, in one specific embodiment, at least two adhesive components may be
positioned parallel to each other and at opposite ends of the container. Upon
dispensing
the flexible food wrap material from the container, the adhesive components
will
independently come into contact with the wrap material at the corresponding
locations
positioned adjacent to such components so that the surface of the wrap
material is coated
with adhesive. Further according to this embodiment, the application of the
one or more
adhesive component may be applied either uniformly or intermittently to the
wrap
material during the coating stages, as it should be understood that the
physical
arrangement of the adhesives on the surface of the container is not intended
to be limiting
herein. Accordingly, one skilled in the art will appreciate that these
arrangements are
exemplary and other arrangements may be formulated and utilized while still
keeping
with the spirit of the present invention.
Moreover, the device for dispensing the adhesive component may further
comprise an application guiding device, such as depicted by Figs. 3, 4a and
4b, for

allowing easy and/or controlled application of adhesive to a surface.
According to Fig. 3,
for instance, a dispensing device for an adhesive component provided in stick
form may
comprise a notch application guiding device to assist the user in placing the
adhesive
component on the article to be adhered or on the flexible plastic film. More
particularly,
an adhesive stick 50 comprises an adhesive component 45 together) with an
application
guiding device 55 in the form of a v-notch located in a rim of the stick
container. The v-
notch application guiding device 55 is adapted to provide easy application of
the adhesive
component onto a desired surface of an article to be adhered or onto the
flexible plastic
film. According to this embodiment, a user can adjust the amount of adhesive
component
45 to be applied to the desired surface by turning a dispenser dial 60 and
then placing the
v-notch shaped application guiding device 55 against the surface of the
desired article to
be adhered or the flexible plastic film and subsequently guiding the
application guiding
device 55 along such.
Similarly, Figs. 4a and 4b depict tubes 65a, 65b of an adhesive component
comprising differing types of application guiding devices 70a, 70b attached to
a
dispensing tip 75a, 75b. Upon applying pressure to the tube, the adhesive
component will
exit a dispensing hole 80a, 80b in the dispensing tip such that the
application guiding
device 70a, 70b can be placed against the article to be adhered or the
flexible plastic film
for assisting and guiding application of the adhesive component. In the
embodiment of
Fig. 4a, application guiding device 70a comprises a protrusion on the
dispensing tip 75a,
which protrusion will act as a guide for contacting the tip along a surface to
be coated. In
the embodiment of Fig. 4b, the application guiding device 70b comprises a pair
of
flexible tips which form a grip adapted to grip an edge to which the adhesive
is to be
applied. The application guiding devices of Figs. 3, 4a and 4b, respectively,
may exist in
various forms, as the figures are not intended to be limiting thereof.
Suitable application
guiding devices include, but are not limited to, edge guides, v-notches,
tracking devices,
ball devices, flexible tip gripping devices and other guiding devices adapted
to provide
easy application of an adhesive component.
In another embodiment, the adhesive component is provided in the form of a
plurality of single use portions. Without being limited by theory herein, it
is envisioned
that during some adhesion applications it may be possible to contaminate the
adhesive
12

WO 03/037768 PCT/US02/34258
component with bacteria andlor other similar pathogenic material. For
instance, during
the adhering of meat-related products, it is envisioned that the meat may come
into
contact with the surface and/or rim of the container or article to be adhered
thereby
contaminating the item's surface with bacteria. During the application of the
adhesive
component to the now contaminated surface and/or rim, the bacteria or similar
pathogenic
material may transfer onto the adhesive component thereby placing subsequent
adhesion
applications at risk of also becoming contaminated. As a result, it may be
desirable to use
single use portions of the adhesive component during these or similar
applications.
According to this embodiment, the single use portions may comprise a separated
layer
portion or an individually wrapped portion.
As depicted by Fig. 5a, for instance, stacked adhesive wipes 85 are provided.
The
stack may be positioned inside or attached to a container comprising the
flexible plastic
wrap for individual application of an adhesive component according to the
invention. As
can be seen from Fig. 5b, an individual packaged adhesive wipe 90 may be
removed from
the stack 85 and an adhesive component layer 100 can be exposed by peeling
away a
backing material 95. Once the adhesive layer is exposed, the adhesive
component may
be wiped upon the desired surface of the article to be adhered or the flexible
plastic film
thereby layering the item with the adhesive component 100 for easy adhesion.
In still other embodiments, a press-on adhesive pack, such as a blister pack,
may
be included with the plastic wrap kits of the present invention. For instance,
Fig. 6
depicts an individually packaged press-on adhesive in accordance with the
present
invention. An adhesive component 110 is housed within an adhesive pocket 105
and may
be exposed upon peeling away a backing material 115 attached to the adhesive
pack.
Upon removing such backing material 115, the adhesive component 110 is
available to
apply to a desired article to be adhered or the flexible plastic film by
applying pressure or
force to the back of the adhesive pocket 105 and thereby forcing the adhesive
component
110 to exit the adhesive pack and onto the desired item.
The invention is further directed to additional lcits. For instance, in one
embodiment the plastic wrap kits comprise (a) a flexible plastic film, and (b)
instructions
for applying an adhesive component to the flexible plastic film or an article
for adhering
the flexible plastic film and the article upon contact therebetween. In
another
13

CA 02460265 2004-03-15
WO 03/037768 PCT/US02/34258
embodiment, a kit comprises (a) an adhesive component, and (b) instructions
for applying
the adhesive component to a flexible plastic filin or an article for adhering
the flexible
plastic film and the article upon contact therebetween. Still other
embodiments comprise
a food wrap kit comprising (a) a flexible food wrap material; and (b) an
adhesive
component wherein the adhesive component is adapted for application to the
flexible food
wrap material or an article for adhering the flexible food wrap material and
the article
upon contact therebetween. It should be understood, however, that the
embodiments
described above are not intended to be limiting thereof.
Methods for Adhering an Article with a Flexible Plastic Film
The present invention also relates to methods for adhering an article with a
flexible plastic film. As used herein, "article" refers generally to any
substrate to which is
desirable to adhere or seal a flexible film, and can include a portion of the
flexible film
itself. In one specific embodiment, article refers to a container suitable for
storage. As
used herein, "adhere" refers generally to the formation of a temporary, semi-
permanent or
permanent barrier, seal andlor barncade that combines or otherwise attaches
the surfaces
of two respective objects. It should be understood, however, that the kits
according to the
present invention can be used to form devices such as pouches, envelops, or
bags.
In one embodiment, methods for adhering an article with a flexible plastic
film
comprise: (a) coating an area of at least one of the article and the flexible
plastic film with
an adhesive component; and (b) contacting the article with the flexible
plastic film at the
