Background and Summary of the Present Invention
[0001] The present invention relates generally to recloseable flexible packages for hermetically
sealing consumable products between generally opposing package films. More particularly,
the invention relates to a flexible recloseable package having a formed food product
cavity which is uniquely suited for packaging thinly sliced food products such as
luncheon meats and a vertically extending portion disposed above the formed product
cavity which contains one or more openings to accommodate a hook member for the vertical
display of the package in a manner such that package provides the consumer with the
ability to observe both sides of a stack of shingled, sliced food products.
[0002] The freshness of food products such as bacon, sliced luncheon meats, cheeses and
the like which are sold prepackaged to consumers depends upon the extent to which
the package is vacuum-packed or gas-flushed and subsequently hermetically sealed.
Often, the purchaser does not use the food products contained within such packages
at once, but rather uses them over an extended period of time. When the initial hermetic
seal of the package has been breached during the opening thereof, a portion of the
total amount of packaged product is often removed. In such instances, the package
cannot be effectively sealed if it does not have a recloseable seal to preserve the
freshness of the food product stored therewithin. The purchaser must then repack the
food products in a different suitably recloseable container.
[0003] Additionally, many prepackaged food products have their package seals located close
to the vertical edge of the package. From a marketing standpoint, such a package cannot
be displayed on a vertical product display, because any display opening would be positioned
beneath the package seal and destroy the integrity of the seal.
[0004] Further, many food products are often presliced and packaged in either on ordered
stack wherein only the front face of the first slice can be viewed from the package
exterior or wherein the slices are randomly arranged or "jumbled" within the package.
Moreover, such packages can not be effectively used to hold within the package thinly
sliced food products such as luncheon meats. Thinly sliced food products of the type
suitable for packaging according to the present invention can be defined as including
between about 22 and 36 slices per inch (between about 8 and 15 slices per cm) of
the vertical height of the food product stack. With this slicing parameter, the resultant
slices are somewhat delicate in nature and are prone to tearing and disassociating
when not properly supported. With such tearing, food products currently commercially
available in which thinly sliced luncheon meats are often packaged in a somewhat disorganized
manner between opposing flexible package panels. The haphazard maner in which these
food products are displayed and viewed by the consumer may create a lack of confidence
therein by a consumer in that the slices appear to be overly processed and of poor
quality. By arranging the thinly sliced food products in a neat shingled stack and
retaining the stack in an aesthetically pleasing position within a flexible package
product cavity in a manner so such that both of the front and rear surfaces of the
shingled stack are viewable from the outside improves the consumer perception of such
food products.
[0005] Accordingly, a need exists for an improved food product package of the type having
multiple seals which can be easily displayed in a vertical setting and which contains
a formed product cavity which product cavity vertically displays a stack of thinly
sliced food products so that front and rear faces of the food product stack are visible
through the front panel of the package.
[0006] The improved packages of the present invention provide significant advantages in
that one of the two package flexible films has a food product cavity formed therein
which is tapered such that the product cavity film has a substantial portion which
is inclined with respect to its covering film. The cover package film is hermetically
sealed to the product cavity film around the entire periphery of the tapered product
cavity. This package first seal is hermetic and is positioned interior of a package
second seal in the form of a recloseable seal assembly so that the package is liquid
tight and suitably retains within the package, the fluids of the products contained
therein, including water, juices, oils and the like. The recloseable seal assembly
is positioned above the package hermetic seal on two opposing faces of vertically
extending package portions of the two package films and therefore the package can
be opened and closed repeatedly to remove a portion or all of the package contents
without destroying the integrity of the package. A "zipper" seal consisting of interengaging
components such as rib and groove fastener elements is the preferred recloseable seal
means. The vertically extending package portions contain openings extending through
the panels above the recloseable seal assembly which permit the packages to be arranged
for display, such as by hanging from a peg or hanger or the like in which the thickest
depth of the tapered product cavity accommodates a folded-over portion of a shingled
stack of thinly sliced food products and wherein the thinner depth section of the
tapered product cavity accommodates the shingled edges of some of the shingled, folded
slices.
[0007] The hermetic seal disposed on the two package film panels around the periphery of
the product has an easy open or "peel" seal portion located adjacent to the product
and interior of and below the recloseable seal. The recloseable seal is opened with
digital pull-apart forces which are also used to open the peel seal. The peripheral
hermetic seal can maintain a vacuum, pressurized and/or gas-flush environment within
the package.
[0008] The recloseable seal components of the packages of this invention are attached to
confronting faces of the vertically extending portions of the two opposing package
films. The two interengaging fastener elements are firmly anchored to the opposing
package panels and are permanently sealed together at their opposite ends, which decreases
the possibility that the package panels may tear or separate when the hermetic seal
is opened.
[0009] A third package seal which is tamper-evident is formed by the opposing vertically
extending portions by sealing their tops together to form a tamper-evident strip which
must be removed or broken to gain access to the package first and second seals.
[0010] Accordingly, it is an object of the present invention to provide an improved recloseable
flexible package for use with stacks of sliced food products, which package has a
first, hermetic peel seal disposed peripherally adjacent to the products and a second,
recloseable seal disposed exterior of the hermetic seal.
[0011] Another object of the present invention is to provide a multi-seal recloseable package
for food products and the like having a first hermetic seal located between two opposing
package panels and having a peelable seal area adjacent to and interior of a second
recloseable seal located between two vertically extending package portions which forms
a recloseable mouth of the package, and a third, permanent seal located above and
exterior to the recloseable seal at the package top.
[0012] Yet another object of the present invention is to provide an improved recloseable
package for sliced food products having a formed product cavity wherein the product
cavity is tapered such that the volume of the same decreases as the product cavity
approaches the top of the package, and wherein recloseable seal elements are attached
to extending portions of two opposing package panels disposed above the product cavity,
and the extending portions have means for supporting the package on a vertical display.
[0013] Still another object of the present invention is to provide an improved package for
sliced food products having a peelable hermetic seal disposed around the periphery
of the food product on a peripheral margin of a formed product cavity interiorally
adjacent a recloseable seal, the recloseable seal extending laterally between package
ends exterior of the peelable seal, a portion of the package containing the recloseable
seal having means to accommodate peg board display hooks and a permanent seal exterior
of the recloseable seal and peg board mounting means having tamper-evident means thereon,
and wherein the sliced food products are displayed so as to permit the texture and
muscle definition of at least some of the slices from the outside of the package.
[0014] These and other objects of the present invention will become more readily apparent
from a reading of the following detailed description.

Detailed Description of the Invention
[0016] Fig. 1 illustrates a recloseable package 10 constructed in accordance with the principles
of the present invention. The packages 10 of the present invention are particularly
suitable for sealing a perishable food product, shown in Figs. 1 and 2 as luncheon
meats slices 12, between a first, formable package panel 14 and a second, non-formable
package panel 16. The first and second package panels 14 and 16 which form the two
sidewalls of the package 10 can be made from a variety of materials including plastic
films, plastic films with heat sealable coatings, multi-layered laminates and/or co-extrusions,
thermoformable materials and the like. A preferred plastic film for assembly of the
packages of the present invention is one which substantially is impervious to air,
oxygen and/or moisture.
[0017] When one or more of the package panels 14, 16 is formed from a multi-layered construction,
it is desirable to use a thin, inner layer which is substantially impervious to air,
oxygen and/or moisture in combination with an outer layer having sufficient flexibility
and desirable structure characteristics so that the laminate can function as a package
panel. For purposes of illustration and discussion, the package panels depicted as
flexible sheets will be shown as a single, heat-sealable lamina. In actual practice,
each flexible package panel will likely be a co-extrusion and/or laminate of two or
more layers which will provide sufficient protection to the product (e.g., oxygen
and moisture barriers) and which conform a hermetic, and if desired, peelable seal
at the inner surfaces. As is known in the art, multi-layered films particularly suitable
for use with the second, non-formable or covering panel 16 are those utilizing three
layers. As is shown in Fig. 3, the outer layer 300 can be a tough polymer, Such as
a printable polyester, for example, one having a thickness of about 0.5 mils (0.013
mm). Enhanced oxygen barrier properties can be achieved by an inner layer or barrier
coating 304, 306, such as a coating of polyvinylidene chloride ("Saran") or of an
ethylene vinyl alcohol copolymer (EVOH film) which is applied to the interior surface
of the exterior layers 300, 308. When printing is desired, a package ink 302 or the
like is most advantageously printed onto either of the inner barrier layers 304, 306.
The outer layer 308 preferably contains a sealant layer or film such as polyethylene,
Surlyn ionomer, ethylene vinyl acetate copolymer (EVA) and the like having a typical
film or sealant thickness of about 2 mils (0.051 mm).
[0018] Similarly, the formable web or first panel can be made of a multi-layered material
well-known in the art for their flexibility and forming characteristics and which
can be run on a form-fill-seal machine. A suitable first panel outer layer 310 can
be a polyamide material, a polypropylene or a polyester. Barrier coatings 314, 315
similar to the inner layers 304, 306 of the cover panel 16 may also be typically provided.
Generally, the outer layer materials are transparent and where the forming web or
first panel 14 is to be non-transparent, an intermediate coloration layer such as
an ink layer 312 is disposed on the inner surface(s) of either of the inner or outer
layers 310, 313. The inner layer 313 of the forming web can incorporate a sealant
film such as polyethylene, Surlyn ionomer, ethylene vinyl acetate copolymer (EVA)
which are desirable because of their inherent capabilities to provide the necessary
hermetic, and peelable, seal. Exemplary materials suitable for such a layer are copolyesters
such as polyvinylchloride, Barex® and other polyester components.
[0019] Returning to the Figures, the package 10 has one package panel 14, in the form of
a generally rectangular flexible, formed first film panel 14 having a formed product
cavity 18, into which is placed a plurality of food product slices 12. The slices
12 are enclosed within the tapered product cavity 18 by an opposing package or cover
panel 16, illustrated as a flexible film sheet 17.
[0020] The luncheon meat slices 12 or the like are desirably positioned in a generally tapered
product cavity 18 within the projecting walls 50 of the product cavity 18 having a
generally wedge-shaped or "bubble" configured compartment 25. The projecting walls
50 are typically formed integrally within the first film panel 14 such as by thermoforming
or vacuum forming. A peripheral flange 52 surrounds the wedge-shaped or bubble compartment
25 and provides a surface to which the second or covering film panel 16 can be adhered
to.
[0021] The configuration of the product cavity 18 is important in that it includes a bottom
wall portion 54, a tapered or inclined back wall portion 56 which are joined together
to form the product compartment 25. Thus, within the wedge-shaped compartment 25,
the bottom wall 54 defines the compartment maximum depth (or front-to-back package
thickness) while the top of the rear wall 56 defines the compartment minimum depth.
In this manner, the volume of the compartment 25 decreases as the tapered rear wall
56 approaches the top of the package 10.
[0022] With this structure, the product compartment 25 is especially suited for enclosing
a shingled stack 22 of thinly sliced food products 12 which stack has been folded
over onto itself in the manner best shown in Fig. 2. When folded over, the food product
stack 22 has a generally U-shaped and solid bottom portion having a substantial thickness
and somewhat planar shape which generally conforms to the shape defined by the product
cavity 18. The inclined rear wall 56 of the product compartment 25 helps to support
the upper portion of the folded stack 12, which is in need of support due to the shingled
nature and thickness thereof, while the bottom wall 54 thereof supports the bottom
portion of the folded stack 12. With this structure, a portion of both sides or faces
4, 5 of the shingled stack 12 can be advantageously viewed through the second or cover
film panel 16, and therefore permits clear viewing of a substantial portion of both
faces of the sliced product which rests against the tapered wall 56 of the product
compartment 25.
[0023] Because the product 12 intended to be stored in the product cavity 18 takes the form
of a plurality of very thinly sliced items, any one of which would not readily remain
in place without the support provided by the other slices, the food products can be
sliced as thin as between 22 and 36 slices per inch (between 8 and 15 slices per cm)
and still be packaged without creating an undesirable visual impression of the sliced
food products. With the present invention, the thinness of the food product slices
facilitates the folding of the slices onto themselves in the shingled, generally U-shaped
configuration illustrated in Fig. 2. With this arrangement, even though the individual
slices are unusually thin for many packaged food products, approximately one-half
of one of the slices 11 is visible through and rests against the package second panel
16.
[0024] After the product cavity 18 is formed in the first film sheet 16, the first and second
film sheets 14 are combined by contacting each other around the product cavity peripheral
flange 52. The first and second film sheets 14, 16 are contacted in a manner so that
a continuous edge seal 40 is achieved therebetween along the product cavity peripheral
margin 52. A portion 42 of the hermetic seal 40 is peelable in nature to maintain
a secure seal during handling and storage that can be peeled back upon the application
of digital forces applied through an outer recloseable seal 26 or the like.
[0025] The package has a first outer recloseable seal 26 illustrated as a conventional interengaging
fastener assembly 27 such as a rib and groove fastener assembly. Although the interengaging
fastener assembly 27 is illustrated as one that is particularly secure for the illustrated
type of package 10, namely, having a length of a formed single rib 28 and a similar
length of a formed groove 29, it will be noted that the interengaging fastener elements
28, 29 of the recloseable seal 26 are not limited to any particular number of interengaging
fastener elements. The rib element 28 need only project outwardly therefrom a sufficient
distance to be securely interengaged with and held by its confronting and complimentary
groove element 29 by two outwardly extending walls defining a channel or groove therebetween.
The groove is of sufficient width to firmly engage the rib when the confronting interengaging
fastener elements 28, 29 are pressed together. Both the recloseable seal 26 and the
interengaging fastener assembly 27 can take any number of various characteristics
and configurations in addition to those described herein.
[0026] Although the two confronting interengaging fastener elements 28, 29 are shown in
FIGS. 1-5 as being extruded integrally with the package panels 14, 16, the fastener
elements may also be formed as separate members as shown in the embodiment 200 illustrated
in FIGS. 6-7. In such instances, the two confronting interengaging fastener elements
280, 290 are separate members, and the rear surfaces thereof may include attachment
means in the form of sufficiently wide flanges 236a, 236b which extend transversely
to the fastener elements 280, 290, to provide appropriate surfaces to adhere and seal
the recloseable seal fastener elements 280, 290 to the opposing film sheets 205, 210.
The flanges 236a, 236b may be as wide as the vertically extending portions 220, 240
to provide reinforcement thereto. Where the interengaging fastener assembly 270 utilizes
separate interengaging opposing fastener elements 280, 290, the fastener assembly
270 may be applied to the confronting surfaces of the flexible film sheets 205, 210
by conventional means such as a suitable adhesive, heat sealing, ultrasonic welding
or the like. The interengaging fastener assembly 270 is preferably of the same length
as the two film sheets 205, 210 and the interengaging fastener elements 280, 290 are
further attached together at their opposite ends 275 so that the fastener material
is not wasted in the trimming of the package 200, and so that it does not interfere
with the peripheral hermetic seal 244 of the package 200.
[0027] Returning now to the first embodiment shown in FIGS 1-5, the package panels 14 and
16 each significantly include an integral vertical package extension 71, 72 which
extends exterior of and above the recloseable seal 26. These integral package extensions
71, 72 have a sufficient vertical extent to accommodate a means for supporting the
package 10 on a vertical display, shown as openings 74. The openings 74 are configured
to receive a peg board display element and are preferably positioned within the vertical
extensions above the recloseable seal 26. Although the vertical package extensions
71, 72 may each be only long enough to accommodate the display openings 74 and any
tamper-evident seal as will be explained later, they may be of substantial width,
so that either the front or rear panels thereof may be imprinted on its inside or
outside surface with desirable information such as merchandise source, description,
price information, advertising or the like.
[0028] The free ends 76, 77 of the vertical package extensions 71, 72 are secured together
by suitable generally permanent bonding means shown as a permanent package third seal
78 located exterior of and above both the package second recloseable seal 26 and the
package mouth 79. The tamper-evident seal of the package is further defined by a line
of weakening 80 shown as perforations, extending longitudinally within the extensions
71, 72 generally adjacent to the recloseable seal 26. The line of weakening 80 can
be administered in any suitable manner such as perforations or scoring. The free ends
76, 77 of the extensions 71, 72 which are sealed together thereby serve as a package
tear strip 90 which will indicate prior opening of the package 10. If desired, an
additional line of weakening may be provided in order to facilitate opening of the
package 10 by grasping the tear strip 90 in one hand and the package body in the other
hand. By this structure, access which permits opening of the recloseable, second seal
fastener elements 28, 29 is possible only upon breaking the third seal by severance
or ripping of the tamper-evident strip 90.
[0029] The embodiments illustrated are advantageous because they are specially suitable
to be formed, filled and sealed on existing machinery, requiring minimal modifications
to the package machinery and/or material used in forming packages having reclosure
strips. In addition, these embodiments provide easily understood tampering indicators
while requiring no other, separate tamper-evident component, inasmuch as the package
extensions perform the tamper-evident feature. As best seen in Fig. 1, it is desirable
to make a portion 42 of the hermetic seal 40 which is beneath and interiorally adjacent
of the recloseable seal 26, a peelable seal to allow the purchaser simple and easy
access to the product. The hermetic seal 40 may be entirely of a peelable nature with
the hermetic seal portion thereof having a stronger bond effected between the covering
film 16 and the product cavity film 18 than in the peelable seal portion 42 interior
of the recloseable seal 26, so that the hermetic seal 40 is, for all intents and purposes
non-peelable. In any event, because the hermetic seal 40 is positioned interior of
the recloseable seal 26, the likelihood of "leakers", i.e., packages wherein air enters
and the product juices or oils escape from the product cavity 18 and enter the recloseable
seal area 26, is greatly diminished.
[0030] During production of packages of the present invention, the product cavity 18 may
be formed by any conventional method in the product cavity film sheets 14, 218 such
as by thermoforming. The fastener elements 28, 29 may be formed integral with the
opposing film sheets or may be applied as a continuous strip of the recloseable seal
interengaged fastener elements 280, 290 may be fed and applied to the access edge
215 of a continuous length of either the cover or product cavity film sheet and sealed
thereto after the food product 12, 212 has been loaded into the food product cavity
18, 218 to form a product-panel assembly. A covering film 16, 210 is then positioned
over the cavity of the product panel assembly and the peelable package seal 42, 246
is formed interior of the outer recloseable seal 26, 226. A vacuum is applied and
then (not simultaneous) the product cavity 18, 218 is gas flushed, if desired. The
opposing cover and cavity film sheets 14, 16 and 205, 210 are then permanently adhered
to each other along their perimeters 42, 242 by heat sealing, ultrasonic welding or
by adhesive or any other suitable means and further are adhered together at the edges
of the package extension portions 220, 240 to create the package hermetic seal 44,
244. The ends 275 of the recloseable fastener assembly are then permanently attached
together and the tamper-evident strip 90, 288 is formed by sealing the package extension
portions 71, 72, 220, 240 together at 78, 258 which is subsequently perforated to
form the package tear strip 90, 288.
[0031] Either before or after forming the package openings 74, 254 a package label (not
shown) or other package graphics may be applied to the package vertical panels in
any conventional manner.
[0032] When it is desired to open a finished package, the user grips the package extension
permanent mouth seal 258 and tears it off along the line of weakening 264 to gain
access to the recloseable seal 226. The vertical panel extensions 220, 240 serve as
pull flanges and are gripped by the user who applies digital pull-apart forces to
open the recloseable seal 226 and the interior peel seal portion 246 of the hermetic
seal 244. The recloseable seal 226 will then separate and open, thereby allowing access
to the inner peelable seal 246. The recloseable seal elements 280, 290 will open to
form a package mouth. Due to the fact that the recloseable seal 226 is adhered to
the package panels 205 and 210 at the ends 275 thereof, the likelihood of destruction
of the integrity of the package 10 is greatly diminished.
[0033] It will be seen that while certain embodiments of the present invention have been
shown and described it will be obvious to those skilled in the art that changes and
modifications may be made therein without departing from the true spirit of the scope
of the invention.
