Abstract
A reclosable fastener assembly (10) for a reclosable plastic bag (18) in which the fastener assembly (10) is sealed to a single wall (14) of the plastic bag. The fastener assembly (10) includes various tear-openable barrier arrangements with the barrier arrangements sealing and protecting the contents of the reclosable plastic bag (18) before being torn open.
Description
FIELD OF THE INVENTION
The invention relates to a reclosable fastener assembly for use with a plastic bag. Specifically, the reclosable fastener assembly with a tear-openable barrier arrangement is sealed to a single film wall of the plastic bag, with the barrier arrangement providing the sealing features of barrier material to the contents of the bag before the barrier arrangement is torn open.
DESCRIPTION OF THE PRIOR ART
The present invention relates to improvements in the bag-making art and may be practiced in the manufacture of reclosable thermoplastic bags and packages of the kind that may be used for various consumer products. Such reclosable thermoplastic bags or packages often include a seal to contain the package moisture and/or to render the package airtight prior to an initial opening of the bag or package. A reclosable fastener assembly protects any remainder of the product therein after the initial opening.
The indicated art is fairly well developed but nevertheless remains open to improvements contributing to the storing qualities of the reclosable bag. In the prior art, Yaeger (U.S. Pat. No. 5,461,845) discloses a reclosable bag and a method of making the bag. The bag has a reclosable fastener assembly connected to a single wall of film used to make the reclosable bag.
It is also known in the art that the sealant, strength and barrier layers of barrier material provide a much higher shield to the transmission of gases and water vapor than other films used in bag manufacturing. An improvement in reclosable bags of the type described above would be to provide various barrier arrangements of barrier material as part of the reclosable fastener assembly, thereby enhancing the barrier properties of the reclosable bag.
SUMMARY OF THE INVENTION
Accordingly, the present invention relates to a fastener assembly and a reclosable bag with the fastener assembly where the fastener assembly is connected to a single film wall of the bag. The fastener assembly generally comprises a strip formed of barrier material having a score line or line of weakness extending along a length of the strip of barrier material with the line of weakness not interfering with the barrier properties of the strip of barrier material. A first interlocking profile is connected to the strip of barrier material and extends parallel to the line of weakness. A mating profile flange is joined to the strip of barrier material on a side of the line of weakness opposite to the first interlocking profile, the mating profile flange including a second interlocking profile mateable with the first interlocking profile. A peel seal feature or closure flange may also be part of the fastener assembly.
In a first use of the fastener assembly with a reclosable bag, a bag is formed from a barrier film material with the bag including front and rear walls, a bottom, top and sides with a line of weakness extending along the bag front wall between the sides. The strip of barrier material of the fastener assembly is joined by a barrier seal to the interior of the bag front wall with the barrier seal encompassing the bag front wall line of weakness and the barrier material line of weakness. In a second use of the fastener assembly, the fastener assembly includes the arrangement of the first use except that the barrier strip includes both interlocking profiles. This is accomplished by the use of an extended barrier strip that bends at an upper section with the two interlocking profiles facing each other on the inner faces of the barrier flange, thereby forming the reclosable fastener portion.
In a third use of the fastener assembly with a reclosable bag, a bag is formed from a barrier film material with the bag including front and rear walls, a bottom, top and sides with a line of weakness extending along the bag front wall between the sides. As part of the fastener assembly, the strip of barrier material is sealed to a flange of the first interlocking profile along a seal line extending between the line of weakness and the first interlocking profile. The strip of barrier material of the fastener assembly is joined by a barrier seal to the interior of the bag front wall and encompasses the bag front wall line of weakness and the barrier material line of weakness.
In a fourth use of the fastener assembly with a reclosable bag, a bag is formed from a barrier film material with the bag including front and rear walls, a bottom, top and sides with a line of weakness extending along the bag front wall between the sides. A barrier seal encompassing the bag wall line of weakness seals the strip of barrier material to an exterior surface of the front wall. A flange of the fastener assembly having the first interlocking profile is connected to an interior surface of the front wall on one side of the bag front wall line of weakness. The mating profile flange is joined to the interior of the front wall on an opposite side of the bag front wall line of weakness.
In a fifth use of the fastener assembly with a reclosable bag, a bag is formed from a barrier film material with the bag including front and rear walls, a bottom, top and sides with a line of weakness extending along the bag front wall between the sides. The strip of barrier material of the fastener assembly is connected to the first interlocking profile. A second profile having a flange is joined to an exterior of the front wall, with the second profile including an interlocking member mateable with the first interlocking profile. A barrier seal encompasses the mateable profiles and the front wall line of weakness, with the barrier seal joining the second profile flange to the front wall on one side of the mateable profiles and the strip of barrier material to the front wall on the opposite side of the mateable profiles. A peel seal joins the barrier strip to the second profile flange on a side of the mateable profiles opposite the line of weakness.
In a sixth use of the fastener assembly with a reclosable bag, a bag is formed from a barrier film material with the bag including front and rear walls, a bottom, top and sides with a line of weakness extending along the bag front wall between the sides. A strip of barrier material of the fastener assembly is connected to the first interlocking profile. A second profile having a flange is joined to an interior of the front wall, with the second profile including an interlocking member mateable with the first interlocking profile. A barrier seal encompasses the mateable profiles and the front wall line of weakness with the barrier seal joining the second profile flange to the front wall on one side of the mateable profiles and the strip of barrier material to the front wall on the opposite side of the mateable profiles. A peel seal joins the barrier strip to the second profile flange on the side of the mateable profiles with the line of weakness. In a seventh use of the fastener assembly with a reclosable bag, the fastener assembly includes the arrangement of the sixth use except that the barrier strip is extended. The extended barrier strip is sealed to the inside of the front on a face of the strip opposite to that of the first interlocking member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in detail wherein like numerals indicate like elements throughout the several views, a reclosable fastener assembly
10
in a first and second use of the present invention is shown in
FIG. 1
as being attached to an associated bag
18
. In the figure, the reclosable fastener assembly
10
including a barrier arrangement is attached to a front wall
14
of the reclosable plastic bag
18
.
As shown in
FIG. 2
, a barrier flange
20
is sealed by an oval barrier seal
22
to the inside of the front wall
14
. The oval barrier seal
22
, and the tacking seals described in the specification, may be accomplished by conventional heat-sealing or any other sealing process known to those skilled in the art. The distinction between the barrier and tack sealing being that the barrier seals preclude air or liquid from passing whereas the tacking seals do not necessarily do so. Also, even though an oval barrier seal is preferred, barrier seals of alternate shapes known to those skilled in the art may be used.
A lower section of the barrier flange
20
of the fastener assembly
10
is sealed to the front wall
14
at a tack seal
24
. The tack seal
24
provides stability for the barrier strip when an interlocking profile
26
of the barrier flange
20
is accessed. The interlocking profile
26
of the figure is shaped to include a protuberance
28
, which is interlockingly received in a groove
30
of an interlocking profile
32
. However, other fasteners of interlocking profiles may be used by those skilled in the art. An interlocking profile
32
adapted to mate with interlocking profile
26
is integral to a mating profile flange
34
. The mating profile flange
34
is sealed to the barrier flange
20
at a tack seal
36
, with the tack seal providing an attachment area to the barrier flange
20
even when the interlocking profiles
26
and
32
are separated from one another.
To access the interlocking profiles
26
and
32
in order to open the reclosable bag
18
, the front wall
14
is provided with a line of weakness
40
. The line of weakness
40
may be a scoring, dimpling or perforation of the front wall
14
in a longitudinally extending direction between the sides of the reclosable bag
18
and within the oval barrier seal
22
. The line of weakness
40
facilitates rupturing of the front wall
14
to provide an opening of the reclosable bag, which in turn allows access to the barrier flange
20
. A single line of weakness
40
is shown and referenced in the following figures; however, a multi-line perforation may be substituted.
To access the interlocking profiles
26
and
32
, the barrier flange
20
has a scored cut
42
which extends partially through the barrier strip between the sides of the reclosable bag
18
encompassed by the oval barrier seal
22
. A single scored cut
42
is shown and referenced in the following figures; however, a multi-line scored cut may be substituted. The scored cut
42
allows the user to tear open the reclosable bag but is shallow enough so that the barrier attributes of the barrier flange
20
are maintained before the barrier flange is torn through.
FIG. 20
, which is later discussed, shows a detail of the score cut
42
and the affected layers of the barrier flange
20
.
As shown in
FIG. 3
, when the line of weakness
40
and the scored cut
42
are opened, access is provided to the interlocking profiles
26
and
32
. The oval barrier seal
22
and the tack seal
36
secure the mating profile flange
34
to the front wall so that the sole pathway
44
to the bag interior is through the profiles when the line of weakness
40
and the scored cut
42
are opened. The pathway
44
allows the user to gain access to the interlocking profiles
26
,
32
and to thereby gain access to the contents of the reclosable bag
18
.
A second use of the fastener assembly
10
is shown in FIG.
4
. In the figure the barrier flange
20
is elongated and bent at an upper section and extended to include the interlocking profile
32
, thereby allowing the interlocking profile
32
to be positioned opposite the interlocking profile
26
. As shown in
FIG. 5
, when the line of weakness
40
and the scored cut
42
are opened, the oval barrier seal
22
secures the barrier flange
20
to the front wall so that the pathway
44
to the bag interior is through the interlocking profiles. That is, the pathway
44
allows the user to gain access to the interlocking profiles
26
,
32
and to thereby gain access to the contents of the reclosable bag
18
.
A third use of the fastener assembly
10
of the present invention is shown in
FIGS. 6
,
7
and
8
. In the front view of
FIG. 6
, a reclosable fastener assembly
10
including a barrier arrangement is attached by an oval barrier seal
22
to the front wall
14
of the reclosable plastic bag
18
, with a line of weakness
40
within the oval barrier seal. In the cross-sectional view of
FIG. 7
, a strip of barrier tape
48
is sealed by the oval barrier seal
22
to the inside of the front wall
14
. The oval barrier seal
22
, along with the barrier tape
48
, prevents air or liquids from entering or leaving the reclosable bag
18
even if the front wall
14
in the area encompassed by the oval barrier seal
22
is ruptured. A closure flange
50
is sealed to the barrier tape
48
at a tack seal
52
and to the front wall at a seal
24
below the lower edge of the strip of barrier tape
48
. The tack seals
24
and
52
provide stability for the closure flange when an interlocking profile
26
of the closure flange
50
is accessed. The interlocking profile
26
is interlockable with an interlocking profile
32
of a mating profile flange
34
. The mating profile flange
34
is sealed to the strip of barrier tape
48
at a tack seal
36
, with the tack seal
36
providing an attachment area to the strip of barrier tape
48
even when the interlocking profiles
26
and
32
are separated from one another.
To access the strip of barrier tape
48
, the front wall
14
of the reclosable bag
18
is provided with a line of weakness
40
. To access the interlocking profiles
26
and
32
in order to open the bag, the strip of barrier tape
48
includes a scored cut
42
. The scored cut
42
of the strip of barrier tape
48
allows the user to tear through the barrier tape, but is shallow enough so that the barrier attributes of the barrier tape are maintained before it is torn through.
FIG. 20
, which is later discussed, shows a detail of the scored cut
42
and the affected layers of the barrier tape
48
.
As shown in
FIG. 8
, when the line of weakness
40
and the scored cut
42
are opened, access is provided to the interlocking profiles
26
and
32
. The oval barrier seal
22
and the tack seal
36
secure the mating profile flange
34
and the closure flange
50
to the front wall so that the sole pathway
44
to the bag interior is through the profiles when the line of weakness
40
and the scored cut
42
are opened. The pathway
44
allows the user to gain access to interlocking profiles
26
,
32
and to thereby gain access to the contents of the reclosable bag
18
.
A fourth use of the fastener assembly
10
of the present invention is shown in
FIGS. 9
,
10
and
11
. In the front view of
FIG. 9
, a reclosable fastener assembly
10
, including a barrier arrangement, is attached by an oval barrier seal
22
to the front wall
14
of the reclosable bag. In this use, a strip of barrier tape
48
with a scored cut
42
is attached to the exterior wall
14
encompassed by the oval barrier seal.
On the inside of the front wall
14
, a closure flange
50
is sealed to the wall of the reclosable bag at tack seals
24
and
52
, with the tack seals
24
and
52
providing stability for the closure flange when an interlocking profile
26
is accessed. The interlocking profile
26
is interlockable with an interlocking profile
32
of a mating profile flange
34
. The mating profile flange
34
is sealed to the inside of the front wall
14
with the tack seal
36
, thereby providing an attachment area for the mating profile flange
34
when the interlocking profiles
26
and
32
are separated from one another.
To access the interlocking profiles
26
and
32
, the front wall
14
is provided with a line of weakness
40
. To access the line of weakness
40
, the strip of barrier tape
48
has a scored cut
42
. As shown in
FIG. 11
, when the line of weakness
40
and the scored cut
42
are opened, access is provided to the interlocking profiles
26
and
32
. The tack seals
36
and
52
secure the mating profile flange
34
and the closure flange
50
to the front wall so that the sole pathway
44
to the bag interior is through the profiles when the line of weakness
40
and the scored cut
42
are opened. The pathway
44
allows the user to gain access to interlocking profiles
26
,
32
and to thereby gain access to the contents of the reclosable bag
18
.
A fifth use of the fastener assembly
10
of the present invention is shown in
FIGS. 12
,
13
and
14
. In the front view of
FIG. 12
, a barrier flange
20
is sealed by an oval barrier seal
22
to the outside of the front wall
14
with the barrier strip sealed to a flange
64
by a peelable seal
66
. The flange
64
is sealed to the outside of the front wall
14
by a section of the oval barrier seal
22
in alignment with the peelable seal
66
. The flange
64
is also sealed to the outside of the front wall
14
by a tack seal
24
. In the cross-sectional view of
FIG. 13
, the peelable seal
66
provides an opening section of the oval barrier seal
22
, allowing access to the interlocking profiles
26
and
32
. However, if the peelable seal
66
is torn open, the barrier flange
20
and the flange
64
protect the line of weakness
40
from also being torn open inadvertently.
As shown in
FIG. 14
, when the line of weakness
40
, the interlocking profiles
26
and
32
and the line of weakness
40
are opened, access is provided to the contents of the reclosable bag
18
. The oval barrier seal
22
secures the flanges
20
and
64
to the front wall so that the sole pathway
44
to the bag interior is through the profiles. The pathway
44
allows the user to gain access to the interlocking profiles
26
,
32
and to thereby gain access to the contents of the reclosable bag
18
.
A sixth use of the fastener assembly
10
of the present invention is shown in
FIGS. 15
,
16
, and
17
. In the front view of
FIG. 15
, a reclosable fastener assembly
10
, including a barrier flange
20
, is attached to the front wall
14
by an oval barrier seal
22
of the reclosable bag
18
with a line of weakness
40
encompassed by the oval barrier seal. In the cross-sectional view of
FIG. 16
, the barrier flange
20
and a closure flange
50
are sealed by an oval barrier seal
22
to the front wall
14
of the reclosable bag
18
. The barrier flange
20
also seals to the closure flange
50
at a peelable seal
66
. The peelable seal
66
provides an opening section of the barrier arrangement, allowing access to interlocking profiles
26
and
32
. Even if the line of weakness
40
is torn open, the oval barrier seal
22
and the peelable seal
66
will still prevent air or liquid from entering or leaving the reclosable bag.
The interlocking profile
32
is integral to the barrier flange
20
and is interlockable with the interlocking profile
26
of the closure flange
50
. A tack seal
24
seals a lower end of the closure flange
50
to the front wall
14
of the reclosable bag. The tack seal
24
provides stability to the closure flange
50
when the interlocking profiles
26
and
32
are opened; however, a larger barrier seal
22
may be used in place of the tack seal
24
. As shown in
FIG. 17
, when the line of weakness
40
and the peelable seal
66
are opened, access is provided to the interlocking profiles
26
and
32
. The oval barrier seal
22
secures the barrier flange
20
and the closure flange
50
to the front wall so that the sole pathway
44
to the bag interior is through the profiles. The pathway
44
allows the user to gain access to interlocking profiles
26
,
32
and to thereby gain access to the contents of the reclosable bag
18
.
A seventh use of the fastener assembly
10
is shown in
FIGS. 15
,
18
, and
19
. In the front view of
FIG. 15
, a reclosable fastener assembly
10
including a barrier flange
20
is attached to the front wall
14
by an oval barrier seal
22
, with a line of weakness
40
encompassed by the oval barrier seal. In the cross-sectional view of
FIG. 18
, a closure flange
50
is also sealed by an oval barrier seal
22
to the front wall
14
of the reclosable bag
18
. The barrier flange
20
also seals to the closure flange
50
at a peelable seal
66
. Even if the line of weakness
40
is torn open, the oval barrier seal
22
and the peelable seal
66
will still prevent air or liquid from entering or leaving the reclosable bag.
The peelable seal
66
provides an opening section of the barrier arrangement, allowing access to interlocking profiles
26
and
32
. The interlocking profile
26
of the closure flange
50
is interlockable with the interlocking profile
32
of the barrier flange
20
. In this use, the interlocking profile
32
is on a face of the extended barrier flange
20
opposite the face of the barrier flange that includes the peelable seal
66
. A tack
24
seals a lower end of the closure flange
50
to the front wall
14
, thereby providing stability to the closure flange
50
when the interlocking profiles
26
and
32
are opened; however, a larger barrier seal
22
may be used in place of the tack seal
24
.
As shown in
FIG. 19
, when the line of weakness
40
and the peelable seal
66
are opened, access is provided to the interlocking profiles
26
and
32
. The oval barrier seal
22
secures the barrier flange
20
and the closure flange
50
to the front wall so that the sole pathway
44
to the bag interior is through the profiles. The pathway
44
allows the user to gain access to interlocking profiles
26
,
32
and to thereby gain access to the contents of the reclosable bag
18
.
A detail of the barrier flange
20
and the strip barrier tape
48
is shown in FIG.
20
. In the figure, the scored cut
42
is sliced through a sealant layer
80
and a strength layer
82
. The sealant layer is typically a linear low-density polyethylene material or similar materials known to those skilled in the art. The strength layer
82
is typically polyethylene terephthalate. By not fully slicing through the strength layer
82
, the integrity of the barrier flange
20
or the strip of barrier tape is maintained. A barrier layer
84
