Abstract
Stand-up, gusseted packages having a reclosable closure mechanism around the periphery of the package mouth. The package has opposite first and second panels, and first and second side panels, which together form a surrounding wall that defines the mouth. The closure mechanism is present on each of the panels. On the first and second panels, the closure mechanism is oriented inward, so that the panels can be interlocked. On each of the first and second side panels, the closure mechanism is oriented outward, and is present as a first portion and a second portion defined by the gusset. To close the package, the closure mechanisms on the first panel and second panel are interlocked, and the side panels are folded inward to allow the first portion and the second portion to interlock. Methods of making the package are described.
Description
TECHNICAL FIELD
This disclosure generally relates to resealable packages having a reclosable zipper closure. More particularly, this disclosure relates to gusseted stand-up packages.
BACKGROUND
Many packaging applications use resealable containers to store or enclose various types of articles and materials. These packages may be used to store food products, non-food consumer goods, medical supplies, waste materials, and many other articles. Resealable packages are convenient in that they can be closed and resealed after the initial opening to preserve the enclosed contents. The need to locate a storage container for the unused portion of the products in the package is thus avoided. In some instances, providing products in resealable packages appreciably enhances the marketability of those products.
One type of reclosable package, the reclosable bag, typically includes first and second opposing panels of a flexible material such as plastic film or paper. For example, the first and second opposing panels may be formed from a single sheet of film folded or wrapped upon itself. The sides of the opposing panels are fixedly connected to each other by heat sealing or by other means. The bottom is sealed closed. The top edges of the panels define a mouth opening which permits access to the contents of the bag. The reclosable package is equipped with reclosable fasteners positioned at the package mouth and extending inwardly across the mouth. Examples of reclosable fasteners include extruded fastener profiles such as complementary rib and groove fastener profiles or male and female fastener profiles.
Improvements in the design of stand-up packages are desirable.
SUMMARY OF THE DISCLOSURE
The present disclosure is directed to a stand-up, gusseted package having a reclosable closure mechanism around the periphery of the package mouth. The package has opposite first and second panels, and first and second side panels, which together form a surrounding wall that defines the mouth. The closure mechanism is present on each of these panels. On the first and second panels, the closure mechanism is oriented inwardly, so that the panels can be interlocked. On each of the first and second side panels, the closure mechanism is oriented outwardly, and is present as a first portion and a second portion defined by the gusset. To close the package, the closure mechanisms on the first panel and second panel are interlocked, and the side panels are folded inwardly to allow the first portion and the second portion to interlock.
In one particular embodiment, a flexible package is provided. The package comprises a first panel, an opposite second panel, a first side panel and an opposite second side panel, together defining a package surrounding wall. The first side panel includes a fold line dividing the first side panel into a first portion and a second portion, and the second side panel includes a fold line dividing the second side panel into a first portion and a second portion. The package further has a bottom attached to each of the first panel, second panel, first side panel and second side panel, the bottom together with surrounding wall defining an interior for retaining an item therein. At the other end, a mouth defined by surrounding wall opposite the bottom provides access to the package interior. A reclosable closure mechanism surrounds the mouth, the reclosable closure mechanism comprising a first interlocking closure profile and a second interlocking closure profile. The reclosable closure mechanism comprises a panel extension of closure mechanism comprising the first interlocking closure profile operably oriented on the first panel and the second interlocking closure profile operably oriented on the second panel, so that the first interlocking closure profile is engageable with the second interlocking closure profile. The reclosable closure mechanism also comprises a first gusset extension of closure mechanism comprising the first interlocking closure profile attached to the first portion of the first side panel, and the second interlocking closure profile attached to the second portion of the first side panel, so that the first interlocking closure profile is engageable with the second interlocking closure profile. Yet further, the reclosable closure mechanism comprises a second gusset extension of closure mechanism comprising the first interlocking closure profile attached to the first portion of the second side panel, and the second interlocking closure profile attached to the second portion of the second side panel, so that the first interlocking closure profile is engageable with the second interlocking closure profile.
In a variation, the reclosable closure mechanism comprises a panel extension of closure mechanism comprising the first interlocking closure profile operably oriented on the first panel and the second interlocking closure profile operably oriented on the second panel, so that the first interlocking closure profile is engageable with the second interlocking closure profile; a first gusset extension of closure mechanism comprising the first interlocking closure profile attached to the first portion of the first side panel, and the second interlocking closure profile attached to the second portion of the first side panel, so that the first interlocking closure profile is engageable with the second interlocking closure profile; and a second gusset extension of closure mechanism comprising the first interlocking closure profile attached to the first portion of the second side panel, and the second interlocking closure profile attached to the second portion of the second side panel, so that the first interlocking closure profile is engageable with the second interlocking closure profile.
Methods of making the packages are also described.

DETAILED DESCRIPTION
Attention is directed to
FIGS. 1 and 2
, which illustrate an example packaging arrangement in the form of a resealable, reclosable, stand-up package
10
. Generally, package
10
is a flexible package, made from, for example, polymeric material such as polyethylene, polypropylene, or other plastics, paper, metal or foil, or any combinations thereof. Package
10
is considered a “stand-up package”, for reasons which will be described below.
Package
10
has an interior containment section
11
defined by first panel
12
, second panel
14
that is positioned opposite first panel
12
, first side panel
22
, and second side panel
24
that is positioned opposite first side panel
22
. Side panels
22
,
24
are foldably connected to panels
12
,
14
; specifically, first side panel
22
is foldably connected to first panel
12
at an edge
16
and to second panel
14
at an edge
17
, and second side panel
24
is foldably connected to first panel
12
at an edge
18
and to second panel
14
at an edge
19
. In the embodiment shown, panels
12
,
14
,
22
,
24
are rectangular in shape, although many different shapes and sizes of panels may be used depending on the desired application. Together with bottom
15
, these panels
12
,
14
,
22
,
24
form a surrounding wall
13
that retains items within interior
11
. Access is gained to interior
11
through mouth
20
. Mouth
20
is defined by panels
12
,
14
,
22
,
24
and preferably, mouth
20
is the same size and shape as bottom panel
15
. In some embodiments, however, it may be desired to have mouth
20
smaller or larger than bottom panel
15
. This can be accomplished, for example, by having panels that taper smaller or larger, respectively, as the panels extend from bottom panel
15
to mouth
20
. It is understood that a flexible package
10
can be easily distorted so that mouth
20
may not have the same shape as bottom panel
15
.
Surrounding wall
13
, that is, panels
12
,
14
,
22
,
24
, can be formed in many ways. Typically, surrounding wall
13
is manufactured from a single piece of web material, such as plastic. A seam, such as a heat seal, may be present at one or multiple edges where the various panels meet. For example, edge
16
between and connecting first panel
12
and first side panel
22
may be a seam. Alternately, a seam may be present within a panel, such as first panel
12
. In yet an alternate embodiment, surrounding wall
13
can be formed from a seamless, tubular material. In preferred embodiments, bottom
15
is generally a flat, planar panel and may or may not include a seam therein.
Side panels
22
,
24
of package
10
are gussets, which are known for providing packages with “stand-up” features. Gussets also allow full extension of package
10
, so as to achieve a large opening at mouth
20
, and also allow convenient folding or collapsing of package
10
when not in use. Typically when making gussets, a single piece of film is folded to form the gusseted panel section, such as side panel
22
. Gusseted panels include a gusset fold
25
, which facilitates folding of side panels
22
,
24
and package
10
.
To allow package
10
to be resealed after its initial opening, package
10
further includes a reclosable closure mechanism
30
at mouth
20
. Closure mechanism
30
can be any one of a variety of closure mechanisms that have interlockable or otherwise engageable first and second profiles. Typically, closure mechanism
30
is a zipper-type closure mechanism. By the term “zipper-type closure mechanism,” it is meant a structure having opposite interlocking or mating profiled elements that under the application of pressure will interlock and close the region between the profiles.
Examples of common reclosable closure mechanisms
30
include those having male and female type profiles or two other engageable profiles. The profiles may be self-mating, meaning that the same profile is used for each of the two mating profiles; in some embodiments, it may be preferred to use self-mating profiles. Typically, the resealable closure mechanism
30
is made of conventional materials, such as a polymeric, plastic material, for example, polyethylene, polypropylene, or PVC. One example of a usable reclosable closure mechanism
30
is shown in FIG.
5
.
Closure mechanism
30
of
FIG. 5
has a first closure profile
32
and a second closure profile
42
, which interlock. First closure profile
32
includes a base strip
34
, a sealing flange or bonding strip
36
, a first mating closure member
35
, and an upper flange or distal end
38
. Mating closure member
35
extends from base strip
34
and generally projects from base strip
34
. Sealing flange
36
depends or extends downward from base strip.
34
and has sufficient structure so that it can be attached to a panel section, such as first panel section
12
of the package
10
shown in
FIGS. 1 and 2
.
Second closure profile
42
is similar to first closure profile
32
in that it includes a base strip
44
, a bonding strip or sealing flange
46
, a second mating closure member
45
, and an upper flange or distal end
48
. Mating closure member
45
extends from base strip
44
and is generally projecting from base strip
44
. Mating closure member
45
, as shown in
FIG. 5
, has three members
45
a
,
45
b
,
45
c
projecting from base strip
44
, whereas mating closure member
35
of first closure profile
32
has two members
35
a
,
35
b
projecting from base strip
34
. Sealing flange
46
depends or extends downward from base strip
44
and can be attached to a second panel section, such as second panel section
14
of package
10
shown in
FIGS. 1 and 2
.
First and second closure profiles
32
,
42
are designed to engage with one another; in particular, first and second mating closure members
35
,
45
are designed to mate and engage with one another. Pressure is applied to closure profiles
32
,
42
as they engage to form the openable sealed closure mechanism
30
. Pulling or otherwise prying first closure profile
32
and second closure profile
42
away from each other causes the two closure profiles
32
,
42
to disengage, opening package
10
of
FIGS. 1 and 2
. This provides access to the contents of package
10
through mouth
20
.
Referring again to
FIGS. 1 and 2
, closure mechanism
30
is present at mouth
20
at each of panels
12
,
14
,
22
,
24
. Specifically, closure mechanism
30
has a panel extension
31
, present on first and second panels
12
,
14
, and a gusset extension
33
, present on side panels
22
,
24
. Panel extension
31
is operably secured to or present on first and second panels
12
,
14
so that first and second mating closure members
35
,
45
of first and second mating closure profiles
32
,
42
(
FIG. 5
) are positioned facing towards each other. That is, panel extension
31
is positioned on first and second panels
12
,
14
so that the two profiles of panel extension
31
can interlock or otherwise engage. When panel
12
and panel
14
are brought together and contact each other at mouth
20
, panel extension
31
can be interlocked to form a seal across mouth
20
.
Gusset extension
33
is operably secured to or present on first and second side panels
22
,
24
so that first and second mating closure members
35
,
45
extend outwardly away from interior
11
of package
10
. Gusset extension
33
is present as a first portion
33
a
and a second portion
33
b
, which are defined by or separated by gusset fold
25
, so that first portion
33
a
is present between gusset fold
25
and panel
14
and second portion
33
b
is present between gusset fold
25
and panel
12
. The closure mechanisms of first portion
33
a
and second portion
33
b
are oriented so that first portion
33
a
is interlockable or otherwise engageable with the closure mechanism of second portion
33
b
. This arrangement is provided so that when package
10
is collapsed, side panels
22
,
24
fold at gusset
25
, and first portion
33
a
and second portion
33
b
are brought together and contact each other.
In package
10
, best seen in
FIG. 2
, gusset extension
33
is not level or aligned with panel extension
31
. Rather, the majority of gusset extension
33
is positioned below, or closer to bottom
15
than, panel extension
31
. This allows panel extension
31
to be interlocked or sealed without interference from gusset extension
33
on side panels
22
,
24
. Additionally, this allows gusset extension
33
to be interlocked without. interference from panel extension
31
. Gusset extension
31
slopes or angles toward bottom
15
as it nears gusset fold
25
. The angle at which gusset extension
33
is present, that is, the angle formed between side edges
16
,
17
of side panel
22
and gusset extension
33
, is shown as angle a in FIG.
2
. Angle α is typically greater than 20 degrees and less than 80 degrees. Preferably, this angle is about 50 to 70 degrees, and most preferably about 60 degrees.
An alternate embodiment of a package
10
′ is shown in
FIGS. 3 and 4
. For ease of identification, those elements in the embodiment of
FIGS. 3 and 4
that are the same or which perform the same function as comparable elements previously discussed with respect to package
10
of
FIGS. 1 and 2
are followed by a prime designation (i.e., “′”). Package
10
′ is similar to package
10
of
FIGS. 1 and 2
in that package
10
′ has a surrounding wall formed by opposite panels
12
′,
14
′, side panels
22
′,
24
′ and bottom
15
′ that define interior
11
′. Mouth
20
′ is surrounded by reclosable closure mechanism
30
′. Gusset
25
′ in side panels
22
′,
24
′ provides package
10
′ with stand-up features and allows expansion of mouth
20
′.
Closure mechanism
30
′ has a panel extension of closure mechanism,
31
′, present on first and second panels
12
′,
14
′, and a gusset extension of closure mechanism
33
′, present on side panels
22
′,
24
′. Gusset extension
33
′ is present as first portion
33
a
′ and second portion
33
b
′, which are defined by the fold of gusset
25
′, so that first portion
33
a
′ is present between gusset
25
′ and panel
14
′ and second portion
33
b
′ is present between gusset
25
′ and panel
12
′. The closure mechanisms of first portion
33
a
′ and second portion
33
b
′ are oriented so that first portion
33
a
′ is interlockable or otherwise engageable with the closure mechanism of second portion
33
b
′ when gusset
25
′ is folded.
In package
10
′, best seen in
FIG. 4
, gusset extension
33
on side panels
22
′,
24
′ is not level with panel extension
31
′; rather, gusset extension
33
′ is positioned below panel extension
31
′; that is, gusset extension
33
′ is closer to bottom
15
′ than panel extension
31
′. This allows panel extension
31
′ to be sealed without interference from gusset extension
33
′. The displacement or offset of gusset extension of closure mechanism
33
′ from panel extension
31
′ should be sufficient so that panel extension
31
′ does not interfere with sealing of gusset extension
33
′, and vice versa. This displacement is typically at least 4 mm and typically no greater than 25 mm. In many embodiments, the displacement or offset of gusset extension of closure mechanism
33
′ from panel extension
31
′ is at least 5 mm and no greater than 20 mm. Preferably, gusset extension
33
′ is positioned about 8 mm below panel extension
31
′. Gusset extension
33
′ should not be spaced so far from panel extension
31
′that leaking out of any items within interior
11
′ of package
10
′ would occur. Although spaced from panel extension
31
′, gusset extension
33
′ is parallel to major length
31
′.
Reclosable closure mechanism
30
,
30
′ is present around all sides of mouth
20
,
20
′ so that package
10
,
10
′ can be securely sealed when desired. Stand-up packages having a reclosable closure mechanism on only two opposite sides have been known, but these designs have a tendency to allow items to pass through.
Although only two variations for offsetting gusset extension
33
,
33
′ from panel extension
31
,
31
′, it is foreseen that other embodiments may also exist.
Preferably each profile of panel extension
31
,
31
′ extends completely across the width of panels
12
,
12
′,
14
,
14
′; that is, each profile of panel extension
31
,
31
′ preferably extends from first side panel
22
,
22
′ to second side panel
24
,
24
′. Similarly, preferably each profile of gusset extension
33
,
33
′ extends completely across the width of side panels
22
,
22
′,
24
,
24
′; that is, each profile of gusset extension
33
,
33
′ preferably extends from first panel
12
,
12
′ to second panel
14
,
14
′.
Preferably, there are no interruptions in either panel extension
31
,
31
′ or gusset extension o
33
,
33
′; each extension of closure mechanism
31
,
33
is continuous and contiguous. The corners or seams at which panel extension of closure mechanism
31
,
31
′ meets gusset extension of closure mechanism
33
,
33
′, are preferably sturdy and secure seals, with no gaps or unsealed area therebetween, so that mouth
20
,
20
′ continuously and contiguously surrounded by reclosable closure mechanism
30
,
30
′; however, it is understood that in some embodiments a gap or other non-continuous element may be present.
Other embodiments of packages in accordance with the present invention are also foreseen. For example, the package can be formed from any number of panels more than three.
Package
10
,
10
′ can be made by a variety of technique. Packages
10
,
10
′ will be made to include reclosable closure mechanism
30
,
30
′ present along the entire periphery or circumference of mouth
20
,
20
′.
Referring to
FIG. 6
, a reclosable closure mechanism
130
is shown that can be incorporated into a package, such as package
110
of
FIG. 7
, according to the present invention by the manufacturing method described below. Reclosable closure mechanism
130
has a first closure profile
132
and a second closure profile
142
, which interlock. Reclosable closure mechanism
130
differs from closure mechanism
30
of
FIG. 5
in that each of first and second closure profile
132
,
142
has an inner closure profile
132
′,
142
′ and an outer closure profile
132
″,
142
″. That is, first closure profile
132
has inner closure profile
132
′ and outer closure profile
132
″ extending in opposite directions from a base strip
134
. Extending or depending from base strip
134
is a sealing flange
136
that can be attached to a panel section, such as first panel section
12
of package
10
shown in
FIGS. 1 and 2
. Similarly, second closure profile
142
has inner closure profile
142
′ and outer closure profile
142
″ extending in opposite directions from a base strip
144
. Second closure profile
142
has a sealing flange
146
extending or depending from base strip
144
. By use of the terms “inner” and “outer” closure profile, it is intended to signify the orientation of the closure profiles upon being incorporated into a package, such as package
10
,
10
′. Inner closure profiles
132
′,
142
′ interlock or otherwise mate or engage with each other, as do outer closure profiles
132
″,
142
″.
A package incorporating reclosable closure mechanism
130
is shown in
FIG. 7
as package
110
. Package
110
has a surrounding wall
113
formed by opposite panels
112
114
, side panels
122
,
124
and bottom
115
. Side panels
122
,
124
are gusseted to provide package
110
with stand-up features; to facilitate folding of package
110
, gusset fold
125
is included. Package
110
has reclosable closure mechanism
130
present at mouth
120
, at the end opposite bottom
115
.
Closure mechanism
130
is present as a panel extension
131
on each of panels
112
,
114
; specifically, inner profile
132
′ and outer profile
132
″ are operably present on panel
114
and inner profile
142
′ and outer profile
142
″ are operably present on panel
112
. Inner profiles
132
′,
142
′ extend inward toward each other and are positioned to be interlocked. Also present is gusset extension
133
, which is present as a first portion
133
a
and a second portion
133
b
, separated by gusset fold
125
, on side panel
122
and also on the opposite side panel, not shown in FIG.
7
.
A process for manufacturing package
110
is shown schematically in FIG.
8
. As illustrated in
FIG. 8
, the process line progresses from right to left so that the final package is at the lower left side of FIG.
8
.
An extended length of reclosable closure mechanism
130
is joined with a polymeric film or other web (not shown) that will form side panels
112
,
114
of the resulting package
110
. The film web can be provided as two pieces, one for each of side panels
112
,
114
, or a single film web can be provided that is folded to provide both side panels
112
,
114
. The fold in the film web will be typically positioned at the resulting bottom
115
of package
110
, although in some embodiments the fold may be positioned close to the mouth, where closure mechanism
130
is attached to the film web; such a construction will require some cutting, slitting, or other perforation of the film web in order to gain access to the interior of the resulting package.
Closure mechanism
130
may be interlocked or separated during the process of attaching closure mechanism
130
to the film web; that is, first inner closure profile
132
′ can be interlocked or engaged with second inner closure profile
142
′, or first closure profile
132
can be separated from second closure profile
142
.
Closure mechanism
130
is attached to the film web at sealing flanges
136
,
146
. The film web can be attached to sealing flanges
136
,
146
on either of the opposite sides of sealing flanges
136
, that is, the inner side on which inner closure profiles
132
′,
142
′ reside, or the outer side on which outer closure profiles
132
″,
142
″ reside.
Although not shown, many suitable attachment mechanisms can be used to attach the extended length of closure mechanism
130
to the film web; for example, adhesive, solvent, ultrasonics, heat, pressure, or any combination, can be used to seal closure mechanism
130
to the film. In some embodiments, this attachment may be a continuous, permanent sealing or attachment; the attachment may be a “pre-seal”, that is, is a spot seal or a weak seal; or, no attachment may be made between closure mechanism
130
and the film at this step of the process. As used herein, the terms “seal” and “pre-seal” mean that two pieces, such as extended closure mechanism
130
and film, are adhered to each other, at least with a temporary bond, preferably with a permanent bond. Various nip rolls, idler rolls, pull rolls, tensioners, bars, positioners, and the like can be used to drive, pull, guide position and otherwise manipulate closure mechanism
130
and the film in respect to one another.
The film web is folded, sealed, and otherwise processed to provide the various features of the package, features such as panels
112
,
114
, side panel
122
and the opposite side panel, and bottom
115
of package
110
. Methods for folding, sealing, and otherwise forming packages having a surrounding wall such as package
110
are well known. Folding of gusset
125
is also well known.
To form package
110
, a section of reclosable closure mechanism
130
is removed. Reclosable closure mechanism
130
is cut, slit, die punched, or processed in other suitable fashions to provide a removed section
150
. The height of reclosable closure mechanism
130
is reduced in the area of removed section
150
. Removed section
150
extends sufficiently deep so that inner closure profiles
132
′,
142
′ are removed from that length of closure mechanism
130
have removed section
150
, but not so deep that outer closure profiles
132
″,
142
″ are disturbed. Removed section
150
has a width, which runs longitudinally along the extended length of closure mechanism
130
and which corresponds to the width of side panel
122
. More specifically, removed section
150
has a length that corresponds to the sum of first portion
133
a
of a first package
110
a
and second portion
133
b
of an adjacent second package
110
b
. First package
110
a
and adjacent second package
110
b
will eventually be separated between first portion
133
a
of first package
110
a
and second portion
133
b
of adjacent second package
110
b
. The chain of connected packages is separated to form individual packages
110
.
It is understood that the various steps in the above-described manufacturing method can be done in many sequences. For example, reclosable closure mechanism
130
can be provided with removed section
150
prior to attaching closure mechanism
130
to the film web. Alternately, closure mechanism
130
can be provided with removed section
150
after the film web has been folded and separated into individual packages
110
. Other variations are foreseen.
Once separated into individual packages
110
, removed section
150
is present at side panel
122
and the opposite side panel where gussets
125
are provided. The elimination of inner closure profile
132
′,
142
′ on the side panels allows gusset
125
to fold inward and interlock outer closure profiles
132
″,
142
″ present as gusset extension of closure mechanism
133
.
The above specification and examples are believed to provide a complete description of the manufacture and use of particular embodiments of the invention. Many embodiments of the invention can be made without departing from the spirit and scope of the invention.
