Description
FIELD
[0001] The present disclosure generally relates to a resealable
label flap positionable to cover an opening in a product package
containing removable articles such that the label flap is pivotally
secured to the package and can be repeatedly removed and reapplied
to access the articles contained within the package. More
specifically, the present disclosure relates to a multi-layer,
resealable label flap having a cutout in a top layer to facilitate
repeated opening and closing of the label flap on the package.
BACKGROUND
[0002] Resealable label flaps are commonly used with many different
types of product packages. One common type of package that utilizes
a resealable label flap includes packaged sheet-like removable
articles that have been thoroughly wetted with a liquid prior to
packaging. This specific product package is generally constructed
from a thin, flexible, liquid-impervious material that has an
opening over which the label flap is removably adhered. Typically,
the label flap attached to the package is a strip of flexible or
semi-rigid thermoplastic material having a removable
pressure-sensitive adhesive applied to one surface of the label
flap. The removable adhesive creates a generally air-tight seal
around the package opening to prevent the packaged removable
articles from drying out during storage.
[0003] In packaging of the type described above, as the articles
are removed, a top surface of the flexible package may become
deformed or waved. As a result, when an attempt is made to reattach
the label flap to the package after opening, the label flap cannot
be properly attached to the top of the package to create a seal
around the package opening. In such situations, it is desirable to
utilize a more rigid material for the resealable label flap and to
incorporate a frame surrounding the resealable flap, which
maintains the shape of the package better than conventional label
flaps and ensures consistent proper sealing of the package. Bending
a more rigid, pivotally secured label flap to access the opening in
a package is more difficult than the use of a more flexible label
flap.
[0004] One known container having a resealable label flap made of
material which is stiffer than the container is set forth in U.S.
Pat. No. 6,026,953 to Nakamura et al. The '953 patent discloses a
single layer reinforcing sheet of between 100 and 130 micrometers
having a cut line that defines a movable label flap with a starting
tab. A crease is formed in the reinforcing sheet by the means of a
press. The crease serves to define a hinge used in the opening and
closing of the flap. The crease prevents the disengagement of the
label flap from the reinforcing sheet. The problem with this
approach is that creases in stiff, rigid materials do not form good
hinges. A hard crease will create a hinge that bends easily, but
the material tends to break at the hinge. A soft crease will create
a hinge that bends hard, and resists bending back on reclosure of
the label flap.
SUMMARY
[0005] The present disclosure relates to a resealable label flap
positionable to cover an opening in a package. The label flap
includes a base layer extending between a first end and a second
end. The base layer includes a first adhesive on a bottom face
surface that permits repeated application and separation of the
base layer relative to the package. The base layer has a starting
tab to permit removal of the base layer from the package. A top
layer is attached to the base layer and includes a second adhesive
on a bottom face surface that permanently attaches the top layer to
a top face surface of the base layer. The top layer is formed with
a cutout that defines a hinge for enhancing separation of the top
layer and the base layer from the package upon manipulation of the
starting tab. The hinge of the present disclosure further enhances
the durability of the resealable label flap in comparison to
conventional resealable label flaps due to the base layer being
devoid of slits or cutouts.
[0006] The hinge-defining cutout extends completely through the top
layer. The cutout is located adjacent the first end of the base
layer, and the starting tab is positioned at the opposite, second
end of the base layer. The base layer and the top layer form a flap
portion having an attachment end and a removable end including the
starting tab. At least one of the base layer and the top layer can
be printed with information. The resealable label flap may include
a frame that extends substantially around the opening of the
package. The top layer is coextensive with the base layer. The
first adhesive is preferably a removable pressure-sensitive
adhesive and the second adhesive is a permanent pressure-sensitive
adhesive.
[0007] In another aspect of the disclosure, the resealable label
flap is positionable to cover an opening in a package containing
removable articles. The label flap includes a base layer extending
between a first end and a second end. The base layer includes a
first adhesive on a bottom face surface that permits repeated
application and separation of the base layer relative to the
package. The base layer has a starting tab to permit removal of the
base layer from the package. A top layer is attached to the base
layer and includes a second adhesive on the bottom face surface
that securely attaches the top layer to a top face surface of the
base layer to prevent separation there between. The top layer is
formed with a cutout defining a hinge. The base layer, the first
adhesive, the top layer, and the second adhesive are formed to
include a flap portion pivotally secured about the hinge to a frame
extending substantially around the flap portion and reinforcing the
package.

DETAILED DESCRIPTION OF THE DRAWINGS
[0021] FIGS. 1-3 generally illustrate a resealable product package
10 having a main package body 12 formed by a cylinder of
liquid-impervious, flexible, thermoplastic material heat sealed on
each end to define an internal space for housing the removable
articles contained within the product package 10. In the embodiment
of the invention illustrated in FIGS. 1-3, the contents of the
product package 10 comprise a series of stacked, individual
products (e.g. cleaning cloths 14) that can be impregnated by
appropriate cleaning solutions. For example, the cleaning cloths
could be wetted baby wipes or hand towels. Although a specific
product package is shown in the Figures, other types of packages
for containing other types of products are contemplated. For
example, the package could be a carton, lid or other shape that
utilizes a resealable label flap.
[0022] As shown in FIG. 2, the package body 12 includes an opening
16 through the package body 12 to provide access into the internal
space of the package body 12 containing the cleaning cloths 14. As
can be readily understood, the individual products contained in the
product package 10 can be removed from the internal space defined
by the package body 12 through the opening 16.
[0023] The product package 10 further includes a resealable label
flap 18 that is applied to the package body 12 to seal the package
body 12 by covering the opening 16. The label flap 18 contacts the
generally smooth, flat top surface of the package body 12, and
forms a generally water and air-tight seal with the package body 12
around the opening 16. The water and air-tight seal around the
opening 16 prevents contamination of the cleaning cloths 14 and
prevents the cleaning cloths 14 from drying out.
[0024] The label flap 18 is resealably attachable to the upper
surface of the package body 12 such that a flap portion 20 of the
label flap 18 can be repeatedly opened and resealed to provide
access to the cleaning cloths 14 contained within the internal
space defined by the package body 12. The flap portion 20 is
defined by a cut line 21 that separates the flap portion 20 from
the outer frame 24. The label flap 18 includes the flap portion 20,
the starting tab 22 and the frame 24 to which the flap portion 20
is pivotally secured. In general, a bottom surface of label flap 18
includes a removable adhesive that allows the flap portion 20 to be
repeatedly peeled from the package body 12, and reapplied thereto
in order to gain access to the opening 16 and then reseal the
product package 10. The resealable adhesive contained on the flap
portion 20 retains its adhesive properties during repeated
application and removal of the flap portion 20 to the package body
12.
[0025] The starting tab 22 is a portion of the label flap 18 in
which the adhesive on the label flap 18 is rendered ineffective or,
in the alternative, not present such that the starting tab 22 does
not adhere to the package body 12 and can be grasped by the user to
pull the flap portion 20 from the package body 12. Referring now to
FIG. 3, the flap portion 20 is defined by the cut line 21 and
extends between a pivotal attachment end 26 and the starting tab
22. To ease opening of the flap portion 20, starting tab 22 extends
to at least the periphery of the frame 24.
[0026] The frame 24 substantially surrounds the flap portion 20 as
well as the package opening 16, and serves to reinforce the
flexible upper surface of the package body 12. The frame 24 also
functions to maintain the overall shape of the flexible package
body 12 as cleaning cloths 14 are removably dispensed therefrom. As
will be understood hereafter, the frame 24 is attached to the upper
surface of the package 12 by the same adhesive applied to the
bottom surface of the flap portion 20.
[0027] As can be best seen in FIGS. 5 and 6, the label flap 18 is a
multi-layer member comprising a base layer 28 and a top layer 30
fixedly attached to the base layer 28. The base layer 28 and the
top layer 30 are coextensive with one another, and extend between a
first end 31 and a second end 32 which includes starting tab 22, as
shown in FIG. 4. Referring back to FIG. 5, the base layer 28 has a
thickness defined by a bottom face surface 34 and an opposed top
face surface 36. In the embodiment illustrated, the base layer 28
has a thickness between 1.6-2.6 mil, although other thicknesses are
contemplated as being within the scope of the present disclosure.
The bottom face surface 34 of the base layer 28 includes a first
adhesive 38 applied on the entire surface area of the bottom face
surface 34. FIG. 4 illustrates that the first adhesive 38
completely covers the bottom face surface 34 of the base layer 28,
including the flap portion 20, the starting tab 22 and the frame
24. A masking layer or coating 40 is applied over the first
adhesive 38 at the removable second end 32 to define the starting
tab 22. In an alternative embodiment, the first adhesive 38 may not
be present along the portion of the bottom face surface 34 to
define the starting tab 22.
[0028] In one embodiment of the disclosure, the base layer 28 is a
single layer polymeric film, and the first adhesive 38 applied to
the base layer 28 is a removable pressure-sensitive adhesive that
retains its adhesive qualities as the flap portion 20 is peeled
from the package body 12 and reapplied thereto. The first adhesive
38 has the desired adhesive properties to form a seal around the
opening 16 while being able to be pulled from the package body 12
without damaging the thermoplastic material forming the package
body 12. Although the base layer 28 is shown as being only a single
layer, the base layer 28 could be formed from multiple layers
bonded together to create the desired thickness for the base layer
28.
[0029] A top face surface 36 of the base layer 28 may be printed
with indicia 42, such as text or graphic images, as represented in
FIG. 10. Such indicia 42 may conveniently include nutritional,
safety, instructional, promotional, regulatory, multi-language or
other information to supplement the information carried on other
parts of the package body 12. If desired, the top face surface 36
may be left unprinted.
[0030] As shown in FIG. 5, the label flap 18 is a multi-layer
structure including the top layer 30 that is fixedly attached to
the base layer 28 that defines flap portion 20, starting tab 22 and
frame 24. The top layer 30 includes a top face surface 46 and a
bottom face surface 48. In one embodiment, a second adhesive 50 is
applied to the entire bottom face surface 48 of the top layer 30 as
shown in FIGS. 5 and 6. In another embodiment, the second adhesive
50 is applied to select areas of the bottom face surface 48 (e.g.
the second adhesive 50 is not applied to the bottom face surface 48
of the top layer 30 at the area adjacent to a cutout 44 (described
herein below). The second adhesive 50 is a permanent
pressure-sensitive adhesive that enables top layer 30 to be
continuously joined to base layer 28. However, the top layer 30
could be attached to the base layer 28 using methods other than the
second adhesive 50. The top layer 30 is preferably a polymeric film
that may or may not be printed with text and/or graphic images on
the top face surface 46. Additionally, the top layer 30 could be
formed from either a single layer or multiple layers bonded
together. In the embodiment illustrated, the top layer 30 has a
thickness between 6-10 mil, although other thicknesses are
contemplated as being within the scope of the present disclosure.
As can be understood, the top layer 30 has a thickness that is much
larger than the thickness of the base layer 28.
[0031] Referring back to FIG. 5, the top layer 30 is formed with a
cutout 44 that extends across and/or intersects with the cut line
21 and defines a hinge 27 at attachment end 26 to enhance
separation of the flap portion 20 from the package body 12 upon
manipulation of starting tab 22. More specifically, the cutout 44
extends completely through the thickness of the top layer 30, and
extends generally across the flap portion 20 between opposite sides
of the cut line 21 at the attachment end 26 thereof. In other
embodiments, the cutout 44 extends completely through the thickness
of the top layer 40 and the second adhesive 50. The cutout 44 is
located adjacent the first end 31 of the top layer 30 opposite the
second end 32. The width of the cutout 44 can vary, and in the
embodiment illustrated, the cutout 44 removed from the top layer 30
has a width of approximately 0.0625'' and 0.1875''. The width of
the cutout 44 could be modified but will always represent a portion
of material that is removed and not just a cut or slit in the top
layer 30.
[0032] When the label flap 18 is positioned on the package body 12,
the removable first adhesive 38 applied to the base layer 28 is
pressed into contact with the package body 12, and the base layer
28 covers the entire opening 16.
[0033] When a user desires to access the cleaning cloths 14
contained within the package 10, the user first grabs the starting
tab 22. Once the starting tab 22 has been grasped, the user pulls
back on the flap portion 20 shown in FIG. 1 to overcome the
removable adhesive bond between the removable first adhesive 38 and
the package body 12. The user continues to pull back on the flap
portion 20, causing the flap portion 20 to separate from the frame
24 along the cut line 21 until the flap portion 20 has been pulled
out of contact with the package body 12 and away from frame 24, as
seen in FIG. 2. Frame 24 remains attached to the upper surface of
package body 12, and serves to anchor the flap portion 20 during
pivotal movement thereof while providing reinforcement for the
package body 12.
[0034] As shown in FIG. 2, the first time the flap portion 20 is
pulled from the package body 12, a perforated oval covering 52
separates from the package body 12 to define the opening 16. The
oval covering 52 remains adhesively attached to the flap portion
20, and prevents contact between the first adhesive 38 and cleaning
cloths 14.
[0035] After the desired number of cleaning cloths 14 has been
removed from the opening 16, the user repositions the flap portion
20 over the opening 16. The first adhesive 38 reseals the flap
portion 20 onto the package body 12 to form the required air-tight
seal around the opening 16.
[0036] In accordance with the present disclosure, the opening and
pivotal movement of the flap portion 20 relative to the frame 24
and package body 12 are enhanced by the hinge 27, which is defined
by the portion of the base layer 28 extending below the cutout 44.
Formation of the cutout 44 in the top layer 30 permits the user to
pull back and pivot the flap portion 20 at the hinge 27, at which
point only the base layer 28 below the cutout 44 connects the flap
portion 20 to the rest of the base layer 28. The separation of the
portion of the top layer 30 defining the flap portion 20 from the
frame 24 creates a tactile response, indicating no further opening
effort is required. Removal or disengagement of the flap portion 20
from the frame 24 and package 10 is prevented because of the
remaining portion of the top layer 30 and the second adhesive 50 on
the base layer 28. As a result, easy bending occurs along the
cutout 44 at the base layer 28 and the first adhesive 38 (as shown
in FIG. 6) without incurring any breakage of the defining layers of
the flap portion 20. Once the flap portion 20 is opened (i.e. in an
open position (see FIG. 2), the hinge 27 biases the flap portion 20
closed or to a closed position. The hinge 27 is also beneficial in
enabling easy closing of the flap portion 20 onto the package body
12. In the open position, the base layer 28 and the first adhesive
38 form a smooth radius curve (see FIG. 6).
[0037] The frame 24 used in the embodiment of FIGS. 1-3 allows a
stiffer material to be used for the label flap 18. When using label
flap 18 with the frame 24, it should be appreciated that locating
the starting tab 22 beyond the periphery of the frame 24 further
improves the accessibility of starting tab 22 so that the flap
portion 20 can be quickly opened.
[0038] Referring now to FIGS. 9-12, the formation of the label flap
18 shown in FIGS. 1-3 will now be described. Initially, a
continuous base material comprised of the base layer 28 and the
first adhesive 38 is unwound. A coating 40 is applied to the first
adhesive 38 at a location corresponding to the starting tab 22. The
coating renders the first adhesive 38 ineffective to form starting
tab 22.
[0039] After the starting tab 22 has been formed, printing may or
may not be provided on the top face surface 36 of base layer 28. As
shown in FIG. 9, the top layer 30 is cut (i.e. die cut) such that
the cutout 44 is defined in the top layer 30 (as described above).
The top layer 30 (which may or may not be printed) and the second
adhesive 50 are then applied to the top face surface 36 of base
layer 28 as indicated by the arrows in FIG. 11. Once the top layer
30 has been applied to base layer 28, the shape of the label flap
18 is cut to form the frame 24 and the flap portion 20. The
finished label flaps 18 are then mounted in spaced apart
relationship on a continuous protective release liner 54.
[0040] Although the label flap 18 of the present invention has been
described as including a frame 24, an alternative embodiment is
shown in FIGS. 7 and 8 wherein the label flap 18 is comprised of
only a flap portion 56 including a starting tab 58. Here, the
construction of the label flap 18 commonly includes a hinge 60
