Description

TITLE OF THE INVENTION
CAP ASSEMBLY AND CONTAINER USED THEREWITH
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates in general to a cap assembly, and more
particularly, to a cap assembly capable of hermetically sealing a container assembly, the cap
assembly undergoing sterilization processes with superheated steam at temperatures in excess
of 280°F. Such sterilization processes are generally suitable for filling of food grade flowable
material including low acid flowable material. Of course, the invention is not limited to any
particular flowable material.
2. Background Art
[0002] The use of flexible containers for the shipment and dispensing of flowable
material has greatly increased in recent years. Increasingly, flexible containers are common
for food grade products. Among other procedures, it is necessary to properly sterilize the
containers to minimize contamination and to maximize shelf life of the products within the
containers. While the sterilization of containers for high acid products has been readily
achieved, there have been problems associated with low acid applications. This is because high acid products have an inherent advantage; microbes and microorganism have difficulty
surviving and reproducing in highly acidic materials.
[0003] The same is not true for low acid materials. In particular, microbes and microorganisms can thrive in a low acid environment. For this reason, the sterilization
procedures for containers utilized in low acid environments are substantially more rigorous
than for high acid environments. In a low acid filling process, for example, prior to and after filling, a spout assembly is exposed to superheated steam for a predetermined period of time.
For example, at a temperature of 280 0F, sterilization is achieved after 13 seconds (the steam
is at approximately 30 psi). At 290° F, sterilization is reached in about 3.6 seconds. In excess of 300° F, sterilization is reached in about 1 second. Temperatures as high as 307°F and
higher (pressure of approximately 60 psi) are utilized to achieve quick sterilization of
components. It will be understood that if chemicals are added for purposes of sterilization,
the temperatures required for the steam can be lower.
[0004] Providing covers for fitments which are both suitable for use in low acid
conditions, and which include openings extending therethrough for dispensing purposes
which cannot substantially withstand the sterilizing environment has proven difficult. First,
the seal over the dispensing opening often fails during the sterilizing procedure. In other
situations, the covers deform in such an environment to the extent that the cover dislodges or
otherwise disengages from the fitment. In either case, the end result is that the material within
the container is destroyed and must be discarded.
[0005] Inasmuch as such sterilizing is highly destructive to fitments and covers,
containers used for low acid applications often include two separate fitments. The fitment
within which product is to be filled generally includes a cap member free of openings. A
second fitment is provided on the container for dispensing. Such a fitment includes a cap
member which is capable of receiving various different dispensers for coupling therewith.
Inasmuch as no manipulation or removal of the second (dispensing) fitment is required
during filling of the container, the second fitment does not undergo the sterilizing procedures described above. Problematically, the use of two separate fitments increases the cost of the containers, the assembly of the containers and the ease of manipulation of the containers.
Furthermore, the greater use of components leads to increased container failure rates.
[0006] Accordingly, it is an object of the invention to provide a cap assembly for a flexible container which includes a resealable dispensing means which are suitable for low
acid applications including sterilization processes which occur at elevated temperatures with
superheated steam.
[0007] It is another object of the invention to provide a cap assembly adapted for
receipt of a number of different dispensers, wherein the cap assembly which is suitable for
low acid applications including sterilization processes which occur at elevated temperatures
with superheated steam.
[0008] These and other objects of the invention will become apparent in light of the
specification and claims appended hereto.
SUMMARY OF THE INVENTION
[0009] The invention comprises a container assembly, having a container, a fitment
and a cap assembly. The container has at least one panel and at least one seal sealing the at least one panel to define a cavity. The fitment is coupled with the container, comprising a
body having a first end and a second end. The second end extends away from the container,
wherein the fitment provides fluid communication with the cavity. The cap assembly is
releasably attachable to the second end of the fitment. The cap assembly comprises a base
and a cover. The base includes an upper surface, a lower surface and an opening extending therethrough. The opening including an upper annular rim extending from the upper surface
of the base and a lower annular rim extending from the lower surface of the base. The cover
is attachable to the base to cover the opening. The cover includes an annular ring that extends
along at least a portion of the upper annular rim of the opening and the lower annular rim of
the opening. The annular ring forms a hermetic seal with at least one of the upper and lower annular rims of the opening.
[0010] In a preferred embodiment, the upper surface of the base includes a shoulder extending at least partially around an outer region thereof. The shoulder defines a valley
therebetween. In one such preferred embodiment, the shoulder comprises a pair of opposing
shoulder components defining a valley therebetween. In another such preferred embodiment,
the shoulder comprises at least four spaced apart shoulder components defining a valley therebetween. In one such embodiment, the four spaced apart shoulder components include a
plurality of arcuate channels positioned therebetween.
[0011] In another preferred embodiment, the cover comprises a body, an arm and a hinge. The body has an upper surface and a lower surface. The arm extends from the body.
The hinge is attached to each of the body and the cap assembly to permit hinged engagement
of the cover to the cap assembly. In one such preferred embodiment, the cover further comprises a tamper evidencing assembly. The tamper evidencing assembly provides
indication as to whether the cover has been moved into an orientation wherein the opening of
the cap assembly is exposed.
[0012] In one such embodiment, the tamper evidencing assembly further comprises a
plug frangibly coupled with one of the cover and the cap assembly and coupled with the other
of the cover and the cap assembly.
[0013] In another such preferred embodiment, the upper surface of the body of the
cap includes a dome region. The dome region is capable of deflecting fluids directed thereat.
[0014] In another preferred embodiment, the upper annular rim of the opening further
comprises an engagement surface, and the annular ring includes an engagement tab, the
engagement surface interfacing with the engagement tab, to, in turn, facilitate the engagement of the cap over the opening.
[0015] In a preferred embodiment, the upper annular rim of the opening further
includes a ring wedge extending therefrom. The lower surface of the cap further includes a
mating channel positioned therein, wherein the ring wedge is capable of interfacing with the
mating channel, to, in turn, create a hermetic seal therebetween.
[0016] In another preferred embodiment, the opening includes a frangible cover
positioned thereacross, to, in turn, preclude fluid communication with the cavity.
[0017] In another preferred embodiment, the frangible cover comprises a molded portion of the cap assembly. The molded portion of the cap extends across the lower annular rim.
[0018] In a preferred embodiment, the cap assembly is capable of maintaining the hermetic seal after exposure to superheated steam of a temperature of at least 280°F for a

DETAILED DESCRIPTION OF THE INVENTION
[0035] While this invention is susceptible of embodiment in many different forms,
there is shown, in the drawings, several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention
and is not intended to limit the invention to the embodiments illustrated.
[0036] It will be understood that like or analogous elements and/or components,
referred to herein, are identified throughout the drawings by like reference characters. In addition, it will be understood that the drawings are merely representations of the present
invention, and some of the components may have been distorted from actual scale for
purposes of pictorial clarity.
[0037] Referring now to the Figures, and in particular to Figure 1, container assembly
10 includes container body 12, fitment 14 and cap assembly 16. Container body 12 comprises
a plurality of panels 20 and a plurality of seals 22. The panels and seals cooperate to define
cavity 26. Of course, the invention is not limited to any particular number of panels and/or
seals, or, a container body having any particular geometric configuration. For example, the
container body may comprise a pillow-type container, or may comprise a gusseted container,
among others. Opening 24 is provided on one of panels 20, or is created by a merging of a
plurality of panels 20 proximate one or more of seals 22. Opening 24 provides ingress into
cavity 26.
[0038] An exemplary fitment 14 is shown in Figure 8 as comprising body 30, base
flange 36, and grasping flanges 37. Body 30 extends from first end 32 to second end 34. Base
flange 36 extends from body 30 proximate first end 32. The base flange 36 is larger than opening 24, such that the panel surrounding opening 24 is welded to base flange 36,
providing a substantially fluid tight connection. Grasping flanges 37 a number of flanges
which are configured for grasping and retaining of the fitment by filling equipment, and for retention by other containers in which the container assembly is positioned (i.e., retention of a
box of a bag in box container assembly). The fitment may comprise a HDPE material, or a
polypropylene material, among others.
[0039] An exemplary cap assembly 16 is shown in each of Figures 3 and 5 as
comprising base 40 and cover 60. With particular reference to cap assembly 16 shown in
Figures 3 and/or 4, base 40 includes upper surface 41, lower surface 42 and opening 43.
Upper surface 41 includes shoulder 44 and valley 46. Shoulder 44 extends at least partially
about the outer circumference of base 40. In the embodiment shown, shoulder 44 comprises first shoulder component 44a and second shoulder component 44b. Each of the shoulder
components mirror each other about axis 100, and are spaced apart from each other such that
they are each less than pi radians. Of course, other shoulders, having varying components of
differing angular length are contemplated for use. In certain embodiments, the shoulder
components may extend beyond the outer edge of base 40 so as to define annular rim 48
extending about portions of the base. The cap may comprise polypropylene, PET or PEEK
materials, among others.
[0040] With reference to the embodiment shown in Figures 5 through 8, shoulder 44
may comprise a plurality of shoulder components. As is shown in detail in Figure 7, the
shoulder components 44a through 44d are separated by arcuate channels 45a through 45d that
extend angularly inwardly toward opening 43. Such arcuate channels are provided to guide steam and other sterilization fluids that are directed at the cap assembly in a circular motion
about the outer perimeter of opening 43 along valley 46. Of course the number of arcuate
channels can be varied. Moreover, the particular shape (i.e., the radius of curvature of the arcuate channels) can be varied within the scope of the invention.
[0041] As is shown in each of Figures 3 and 5, valley 46 extends between the
shoulder components and substantially surrounds opening 43. In such a configuration, the
size of the opening can be varied without requiring a redesign or a restructuring of the
shoulder components. In turn, only the surface area of the valley changes as the opening is varied through an entire range of different sizes.
[0042] Referring now to Figures 4 and 6, lower surface 42 of base 40 includes outer retaining annular rim 50 and inner retaining annular rim 52. The two annular rims are
substantially concentric and extend outwardly from the lower surface of the base. The two
annular rims are separated a distance from each other such that they cooperate to define
channel 54 therebetween. Channel 54 is sized so as to facilitate the receipt of second end 34
of body 30 in an interference fit. In certain embodiments, one of the second end of the body
and the two annular rims may include a structure which facilitates the positive retained
engagement of the fitment, such as retention zone 91 which facilitates positive retained engagement of distal end 32 of fitment 14.
[0043] As is shown in Figures 4, opening 43 extends through upper surface 41 and lower surface 42. The opening 43, as explained above can have any number of different
shapes and sizes. The opening is positioned within valley 46 of the upper surface. Opening 43
includes lower opening annular rim 73 extending about the circumference thereof along lower surface 42. Engagement surface 121 extends outwardly about the outer surface of
annular rim 73. Additionally, opening 43 includes upper opening annular rim 75 extending
above valley 46 about the circumference thereof along the upper surface 41 thereof. The
annular rims are preferably spaced apart so as to create elongated passage 77.
[0044] The upper and lower opening annular rims provide enhanced rigidity to
opening 43, provide an anchor to which dispensing assemblies may be attached and furthermore in combination with cover 60 providing a sealing assembly (preferably hermetic)
for opening 43. For example, as is shown in Figure 8, probe connector 110 can be coupled to
lower opening annular rim 73. In the embodiment shown, the bottom end of probe connector
110 interfaces with the lower opening annular rim 73 so as to preclude release thereof. In
other embodiments, a different connector (i.e., a valve, hose, etc.) can be attached and
releasably retained thereto under a number of different attachment structures.
[0045] In certain embodiments, such as is shown in Figure 4, a frangible cover 59 can
be positioned over opening 43. hi particular, the frangible cover precludes passage of material
through opening 43. The cover can be broken, peeled or otherwise dislodged from the sealing
position when ingress to cavity 26 through opening 43 is desired. In certain embodiments, the
frangible cover may be comprise a thin polymer wall that extends across opening 43. The thin polymer wall can be molded into the fitment during molding thereof.
[0046] Referring now to Figure 2, cover 60 includes body 62, handle 64 and hinge 66.
Cover 60 is configured so as to substantially correspond to the configuration of valley 46.
Moreover, the thickness of cover 60 substantially corresponds to the depth of valley 46. Of
course variations are likewise considered. [0047] With reference to Figures 3 and 4, body 62 includes upper surface 68 and
lower surface 70. Upper surface 68 includes domed region 72 positioned thereon. In the
embodiment shown, the domed region is positioned in the center of cover 60 and corresponds
substantially to the size of opening 43. Lower surface 70 includes outer perimeter region 79,
recessed region 74, annular ring 76 and reinforcement member 78. Recessed region 74 is recessed relative to outer perimeter region 79 at engagement ring edge 122. Annular ring 76
is positioned so as to substantially correspond to upper opening annular rim, such that the upper opening annular rim is positionable within the channel defined by the engagement ring
edge 122 and the annular ring. When closed, annular ring 76 extends into opening 43 beyond
the plane created by valley 46, to, in turn, provide enhanced rigidity to the cap member. Due
to the tight tolerances of the respective components, the contact of the annular ring creates a hermetic seal along a portion of the length of the upper and lower annular rim (denoted by the
range between A and B of Figure 13). Preferably the hermetic seal extends to the lower
opening annular rim. Advantageously, the cover is selectively removable and replaceable so
as to provide a substantially sealed engagement. In turn,, the container can be resealed any
number of times after initial opening thereof and after some of the contents have been
withdrawn.
[0048] Additionally, as is shown in Figure 4 (as well as in Figures 6 and 13)
engagement ring 122 engages against engagement surface 121 of upper opening annular rim
75, to further facilitate engagement of the cap. Certainly, in other embodiments, the annular
ring 76 can extend about the upper opening annular rim.
[0049] In one embodiment, as is shown in Figures 12 and 13, upper opening annular rim 75 further includes ring wedge 141 extending about the outer periphery of the rim. A
corresponding channel 143 extends about the recessed region 74 of the lower surface of the
cover. Upon application of the cover to the opening, ring wedge 141 extends into corresponding channel 143. The channel and the ring are dimensioned and shaped such that
engagement of the components is insured, hi turn, a hermetic seal is created therebetween.
Advantageously, the application of pressure upon the cover member by the superheated steam
only increases contact between the ring wedge and the channel, thereby strengthening the hermetic seal therebetween.
[0050] Handle 64 is shown in Figures 3 and/or 4 as extending from the cover 60. hi
the embodiment shown, the handle is positioned between opposing shoulder components 44a
and 44b. Handle 64 provides a means by which to manipulate cover 60 relative to base 40. hi
the embodiment shown, handle 64 includes tamper evidencing assembly 82. The tamper evidencing assembly comprises plug 84 which is coupled to handle 64 by frangible members,
such as frangible members 86. The plug is securable to upper surface 41 of base 40 by way of
heat welding, adhering and co-molding, among others. The securement of the plug to the
upper surface is stronger than the frangible members. Thus, the frangible members will break
leaving the plug attached to the upper surface, to, in turn, indicate that the cover has been removed at least one time from the sealed position.
[0051] hi another embodiment, as is shown in Figure 11, tamper evidencing assembly
82 may comprise a frangible tab 107 which is attached to each of the cover and the associated
base of the cap member, hi the embodiment shown, the frangible tab 107 extends about the
full circumference of the cover assembly. Of course, in other embodiments, frangible tab 107 may extend only partially about the circumference of the cover, attaching to the base of the
cap assembly at discrete locations.
[0052] Hinge 66 is shown in Figures 3 and 4 as comprising a live hinge having hinge
members 83, 85 and biasing member 87. The hinge members extend on opposing sides of
biasing member 87. Each of the members are attached to each of cover 60 and base 40, and
comprise an integrally molded live hinge. Of course, other configurations are likewise
contemplated for use, including, but not limited to other living hinge configurations, as well as attachment structure which all for greater separation of components.
[0053] Referring now to Figure 10, in other embodiments, the cover may be coupled
to the underlying cap assembly by way of releasable engaging members 103, 105. Each
engaging member is capable of matingly engaging structures on the cover assembly to releasably retain the cover to the cap assembly, hi other embodiments, such as the
embodiment shown in Figure 9, a single engaging member 103 can be utilized in cooperation
with hinge 66. The releasable engaging member may be frangibly associated with the cap
assembly so as to provide indication as to tampering of the cover relative to the cap assembly.
[0054] hi other embodiments, such as the embodiment shown in Figures 5 through 8,
12 and 13, the hinge can be eliminated, wherein the cover and cap comprise two separate
components, hi such an embodiment, handle 64 may comprise a flange which extends at least partially on the outside of annular rim 76, to provide a surface by which the cover can be
removed.
[0055] In operation, the container apparatus is first assembled from a plurality of
panels having a plurality of seals positioned thereon. Next, the fitment is coupled to opening 24 of the container. Finally, cap assembly 16 is coupled to the fitment, thereby sealing cavity
26 from fluid communication with the surrounding environment.
[0056] Once fully assembled, the container may be gamma irradiated, hi typical high acid filling process, the container may undergo approximately 15 kGy of gamma irradiation.
In a typical low acid filling process, the container may undergo approximately 30 kGy of gamma irradiation. Of course, the particular quantity of gamma irradiation that is transmitted
to the container can be varied without departing from the scope of the invention. [0057] Once irradiated, the cavity is substantially sterilized. The container is next
directed to a fill device wherein a chamber is positioned in sealing engagement with at least a
portion of the fitment. Once the chamber is sealed to the fitment, a superheated steam is
directed onto the fitment and the cover to effectively sterilize the region. For food products,
sterilization can be achieved through an application of superheated steam at temperatures
generally in excess of 250°F. The higher the temperature, the lower the exposure time needed to achieve sterilization. For example, at 250°F, sterilization is reached in approximately 600
seconds. At 26O0F, sterilization is reached in approximately 170 seconds. At 27O0F,
sterilization is reached in approximately 52 seconds. At 2800F, sterilization is reached in
approximately 13 seconds. At 2900F, sterilization is reached in under 4 seconds. At
temperatures in excess of 3000F, sterilization is reached in approximately 1 second.
Accordingly, to decrease the time necessary for the superheated steam application, the sterilization process generally occurs at temperatures in excess of 2800F. Of course, the cap is
not limited to use in association with any particular sterilization process, or with the use of
superheated steam. Indeed, in certain operations chemicals may be utilized alone, or with steam (including but not limited to superheated steam) at various temperatures.
[0058] After the application of superheated steam, the chamber and the contents (i.e.,
at least a portion of the fitment and the cap assembly) are sterilized. The filling process is
then initiated. To initiate the process, the cap assembly is removed from the second end of the
fitment 14. Once removed, the fill valve is placed in fluid communication with the fitment,
and, the fill material is directed into cavity 26. After filling, the valve is removed and the cap
assembly is replaced onto the fitment. Inasmuch as the fitment and the cap assembly remain
within the chamber (which is substantially sterilized), the fill process occurs in a substantially
sterile environment.
[0059] Once recapped, the container can be removed from the filling device and the
container is ready for use. hi certain embodiments, the container assembly can be inserted
into an outer box (i.e., a bag in box). The cover can then be removed from the cap, and the fitment can be attached to a dispensing valve, hose or the like. Due to the unique construction
of the cap and the cover, after some of the material within the container has been dispensed,
the cover can be repositioned over the cap to effectively seal the container. As such, a
resealed container can be stored for future use.
[0060] Advantageously, the present fitment and cap assembly are capable of
withstanding the sterilization process utilized in association with filling processes wherein
the flowable material comprises a low acid food product. The cap and the cover remain
firmly positioned upon the fitment and the cap, respectively, and the hermetic seal is maintained throughout the sterilization process. Moreover, the cover can be selectively. closed
or opened repeatedly, as desired. [0061] The foregoing description merely explains and illustrates the invention and the
invention is not limited thereto except insofar as the appended claims are so limited, as those
skilled in the art who have the disclosure before them will be able to make modifications
without departing the scope of the invention.
