Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] This application is a continuation-in-part of pending U.S.
application Ser. No. 09/906,458 filed on Jul. 16, 2001, which is a
continuation-in-part of pending U.S. application Ser. No.
09/538,540 filed on Mar. 30, 2000. The present invention relates to
a rigid container or canister suitable for storing food products
(consumables) with a multi-functional cap. In one embodiment, the
cap nests over the mouth end of the container when the container is
sealed, but can also nest with the base end of the container for
storage while the container is in use. A sub-container or
promotional item can be placed within the cap and kept separate
from the food product. Further, when inverted, the cap seats into
the mouth end of the container, thereby acting as a bowl. The
container consists of a molded body that can be wrapped with a thin
film graphics carrier. In one embodiment of the invention, the thin
film graphics carrier contributes to the barrier properties of the
container. The container stands unsupported for a shelf display or
can be vendable from soft drink vending machines.
[0003] 2. Description of Related Art
[0004] The design and construction of packaging for containers of
consumables, such as potato chips, tortilla chips, chip and dip
kits, or other snack products, requires the consideration of
several sometimes competing factors. One factor to consider is that
the container must be designed to protect the product contained
therein from degradation, microbial spoilage, and physical damage.
Ideally, the container should possess barrier properties that limit
or prohibit the migration of oxygen, moisture, and light through
the container when sealed. Oxygen and moisture migration into a
container reduces the product's shelf life. Product degradation can
also be slowed if the barrier properties of the container limit the
exposure of the product to light. Breakage of the product can be
limited by either placing the product in a rigid container or
providing sufficient slack-fill in a non-rigid container to provide
an air cushion within the container.
[0005] Another factor to consider regarding consumables container
design is the marketing aspect, or presentation, of the container.
A consumables container should provide an appealing presentation of
the product contained therein. It is often desirable that the
container be capable of standing unsupported on a store shelf.
Further, the container must be capable of supporting graphics
either affixed to the container or embedded in the container to
assist with brand recognition and the appearance of the packaging.
Many prior art containers are constructed of at least three layers,
and typically more, consisting of a moisture barrier, an oxygen
barrier, a light barrier, and a graphics carrier, all of which are
molded or shaped for a desired presentation.
[0006] The specific barrier properties of a container are
frequently dependent on the product that must be protected. For
example, some products, such as crackers, do not need an oxygen
barrier for protection. Likewise, other products may not need a
moisture barrier or a visible light barrier. Consequently,
containers are usually designed with the minimal barrier properties
required to protect the specific products to be contained
therein.
[0007] Another factor in consumables container design is the
economics and efficiencies of filling and shipping the container.
Containers are ideally constructed to easily and efficiently fill
with product on a production line. Further, the containers must fit
economically into boxes or crates in order to minimize shipping
costs. It might also be beneficial for individual components of a
container, such as a container cap, to be easily stacked for
shipment and handling prior to installation on the container.
[0008] Another design criteria for consumables container design is
the cost and ease of construction of the container. Every layer
added to the container may provide additional desired barrier
properties. However, the addition of every layer also drives up the
cost of constructing the container. Generally speaking, less
expensive containers limit the layers of material and the amount of
material involved in the construction of the container.
[0009] A design of a specific consumables container may also have
many application specific design criteria. For example, marketing
considerations may make it desirable to construct the container so
that it is particularly useful in dispensing or holding a product
while being consumed by the consumer. The container may be designed
with an easy-open top, a dimension or shape that makes it easy to
hold the container in one hand, and an opening sufficient in size
for the consumer to retrieve the product from the container by
pulling out the product by hand. Another example of an application
specific consideration involves dispensing consumables containers
from what are traditionally soft drink vending machines. Such
containers, referred to as "vendable" containers, must be designed
of an appropriate dimension and weight to be easily loaded and
dispensed from standard soft drink vending machines. Such
dimensions can also make a container suitable for use with a cup
holder in an automobile.
[0010] Likewise, the ergonomics of the container must be
considered. The container can be designed to be easily grasped and
held in one hand. Some containers are designed to allow for direct
consumption of the product by pouring the product out of the
container into the consumer's mouth.
[0011] The utility of various components of the container is also
an important design consideration. The cap that seals the container
might also be used as a bowl or cup to hold the product for
consumption by the consumer. The container itself may provide for
other functional uses or provide for special re-seal
capabilities.
[0012] The above items are not all-inclusive, but representative of
design considerations regarding consumables containers. Frequently,
these and other design considerations are in conflict and require
balance and compromise. For example, a certain marketing look or
presentation may be impractical because it reduces packaging
efficiencies or gives rise to difficulties in production line
filling or construction. Heavy and multi-layered construction
provides ideal barrier properties for protecting a product, but can
greatly increase the cost and complexity of construction. The
addition of consumer oriented features, such as easy open and
resealable tops, can also introduce complexities in manufacturing
and increase overall cost. As a result, the snack food industry has
yet to develop a container that is of simple and inexpensive
construction, provides a unique shelf presentation, provides
various consumer friendly features that allow for single-handed
operation, provides for storage or multiple products, and provides
for sufficient barrier properties in an economical and efficient
design.
[0013] In particular, there does not exist in the prior art a
vendable consumables container with a cap that performs several
functions in an efficient, simple, and economical design. Most
containers with removable caps do not provide for any function for
the removable cap other than for use to reseal the container.
Further, there is typically no provision on the container for
stowage of the removable cap while the container is in use.
Frequently, a second cup or bowl must be used, independent from the
container, when the consumer wants to pour out only a portion of
the food product in the container. While some prior art containers
combine two of the features listed above, none of them incorporate
a cap design that acts as a cup that can be placed on top of the
container, can be stored on the bottom of the container when not in
use, and used to seal the container for storage of the food
product, along with a container design that lends itself to
single-handed use by the consumer in a vendable and shelf
presentable package. Further, none of the prior art containers
incorporate a cap design that acts as a separate compartment for a
second product to complement the primary product such as dip for
potato chips. Prior art "chip and dip" combination containers are
very expensive, difficult to use, bulky, and unattractive. For
example, one prior art design comprises a bulky thermoformed tray
that is used to contain a bag of chips and a dip container. The
tray is sealed with a large film to hold the contents in place. The
end user removes the film, opens and pours the bag of chips into
the tray and then eats from this large package. Because of its
bulk, the package is not very portable, and the costs of
manufacturing are high.
[0014] Accordingly, a need exists for an easily manufactured
consumables container that incorporates a multi-functional cap with
an economical design. The container should provide acceptable and
appropriate barrier properties, as well as physical containment and
protection of the product. The multi-functional cap should act as a
sealing means on the mouth end of the container, should store on
the bottom of the container when not in use, and should act as a
cup or bowl that can be seated on the top of the container for
single-hand use by the consumer. The multi-functional cap should
also be adaptable for storing a second product such as dip or a
promotional item separate from the main product. The
multi-functional cap should allow for effective and efficient
re-sealing of the unused portion of the product(s). The container
should be capable of standing unassisted on store shelves or,
alternatively, being dispensed from a soft drink vending machine.
Such a design should be simple and inexpensive to manufacture,
provide for packaging and filling efficiencies, and be intuitively
functional to the consumer.
SUMMARY OF THE INVENTION
[0015] The proposed invention comprises an economically designed,
vendable container for snacks and other perishable foods with a
multi-functional cap. One embodiment comprises a generally
cylindrical container with a multi-functional cap nested over the
mouth end of the container and an outer film wrapped over the cap
and container after the container is filled. The outer film can
also complement the barrier properties of the container.
[0016] The invention is simple and inexpensive to manufacture,
provides adequate protection for the product contained therein, and
is easy to use for the consumer. The multi-functional cap reseals
the container, can be used as a bowl for product and as a
compartment for a second product such as a condiment or promotional
item. The container is capable of standing unassisted on a store
shelf or being dispensed from a soft drink vending machine. The
container is an improvement over the prior art in ease of
manufacture, packaging efficiencies, and functional use by the
consumer.

the present invention will become apparent in the following written

DETAILED DESCRIPTION
[0034] FIGS. 1a and 1b show perspective views of a cylindrical
embodiment of the present invention. Referring to FIG. 1a, the
container comprises a receptacle 100 which provides for the
rigidity of the container as well as necessary oxygen and moisture
barrier properties. The receptacle 100 can also be opaque in order
to preclude exposure to light on the product contained therein. The
receptacle 100 is typically blow molded and can be constructed of
high density polyethylene, which provides for effective moisture
barrier properties, or ethethylene vinyl alcohol, which provides
for effective oxygen barrier properties. Examples of other suitable
material for use in constructing the receptacle include
polyethylene and polyester. In an alternative embodiment, the
receptacle 100 can be multi-layers or constructed of a material
that provides for both effective oxygen and moisture barrier
properties.
[0035] The receptacle 100 comprises a mouth end 102, a base end
104, and a slightly circumferentially constricted central section
106. The constricted central section 106, in one embodiment,
comprises corrugation 108 about the circumference of the container.
This corrugation 108 provides additional circumferential strength
and, in combination with the tapering to slight constriction of the
central section 106, a convenient hand grip for the consumer.
[0036] The mouth end 102 of the receptacle 100 is tapered to nest
with a cap 110. The mouth end 102 is also dimensioned such as to
allow the cap 110 to be inverted and act as a cup when placed or
seated into the mouth end 102, as will be described in further
detail in conjunction with FIG. 3. The cap 110 is also dimensioned
to nest over the container base 104, as will be further described
in connection with FIG. 4.
[0037] The first step in manufacturing the container of Applicants'
invention involves constructing the receptacle 100. This is
typically done by blow-molding of the material selected, but could
also be accomplished by injection molding, thermal forming, or
other means used in container manufacturing. After the receptacle
100 is removed from the mold, it can be filled with product or
consumables, such as corn-based snack foods, dropped into the
receptacle 100 through the mouth end 102. After the receptacle 100
is filled with product, a removable seal (shown as reference 220 in
FIG. 2a) is secured over the mouth end 102 of the container by
methods well known in the industry. This removable seal can be, for
example, a metalized polyester secured by a heat and pressure seal
or other means. Once the removable seal is placed over the mouth
end 102, the cap 110 is then nested over the mouth 102.
[0038] Referring to FIG. 1b, an outer layer 102 is then wrapped
over the cap 110 and a portion of the receptacle 100. In the
alternative embodiment that requires more barrier properties than
provided by the receptacle 100, the selection of whether the outer
layer 112 is a material that also provides additional oxygen
barrier, moisture barrier, or light barrier properties depends on
the selection of the material used for the receptacle 100. If the
receptacle 100 material provides an oxygen barrier, the outer layer
112 material selected could provide moisture barrier properties,
and vice versa. The outer layer 112 can also act as a graphics
carrier. Alternatively, the container can be constructed without an
outer layer 112 by embedding graphics within the receptacle 100 or
screen printing graphics directly on the receptacle 100.
[0039] The outer layer 112 can comprise a shrink-wrap and made of,
for example, polyethylene terephtalate to provide additional oxygen
barrier properties or polypropylene to provide additional moisture
barrier properties. Both materials can also act as acceptable
graphics carriers. One embodiment of the container uses a polyvinyl
chloride shrink wrap 112, which adds additional light barrier
properties when used as a graphics carrier and some additional
moisture barrier properties.
[0040] The list of acceptable materials for use in either the
receptacle 100 or the outer layer 112 is not exhaustive. Rather,
any material available in the field of art that provides the
adequate barrier properties along with desirable molding, rigidity,
and graphics characteristics can be used in combination. This is
true for all embodiments of the invention.
[0041] To further reduce manufacturing costs and complexity, the
embodiment shown in FIG. 1b illustrates that the outer layer 112 is
wrapped such that it covers all but the top end 110a of the cap 110
and the bottom or base 104 of the container. By not wrapping the
top of the cap 110a and the bottom 104 of the container, the
application of the outer layer shrink-wrap 112 is simplified and
requires less material per container. The potential loss of barrier
property provided by the outer layer in this design is minimal
because the bottom 104 of the container will typically rest on a
hard surface and, at least until opened, the container mouth 102
further incorporates a removable seal which can provide substantial
barrier properties of its own. Alternatively, the outer layer 112
could be wrapped only over the receptacle 100, thereby further
saving manufacturing costs.
[0042] In a vendable embodiment of the present invention, the
height of the receptacle 100 from the mouth end 102 to the bottom
104 is approximately 6.63 inches. The diameter of the receptacle
100 at its maximum dimensions above and below the center section
106 is approximately 2.75 inches. The maximum circumference of the
container above and below the center section 106 should be
identical, in order to provide support between adjacent containers
when proceeding down a processing line, when stacked on store
shelves, or packed for shipping, by allowing contact between the
containers both below and above the center of gravity of each. This
contact at the bottom and top of adjacent containers helps with the
stability of the containers when placed in contact. The minimum
circumference of the center section 106, in this vendable
embodiment, is approximately 2.4 inches. The total height of the
container with the cap 110 nested on the mouth end 102 in this
embodiment is 7.84 inches. Such dimensions are suitable for vending
the container from a standard 20-oz. soft drink vending
machine.
[0043] As shown in FIG. 1a, the mouth end 102 is slightly tapered
both to properly nest in the cap 110 and to provide a pouring
function from the mouth end 102 into the cap 110 or other
receptacle. Further, the tapered shape helps prevent unintended
spillage of the product out of the mouth end 102.
[0044] FIGS. 2a and 2b show the container in use by a consumer.
First, the consumer removes the cap 210 by twisting the cap 210 and
breaking the outer layer at the intersection of the cap 210 and a
rim 214 below the mouth end 202. The removal of the cap 210 reveals
the seal 220 affixed to the mouth end 202. The seal 220 is removed
by pulling on an exposed tab 222.
[0045] Once the seal 220 is removed, the contents of the container,
such as a puff-corn snack 230, can be poured into the cap 210. The
product 230 can also be poured directly into the consumer's mouth.
To reseal the container, the cap 210 is again nested over the mouth
end 202.
[0046] The container is designed to provide a convenient one-hand
use, as illustrated in FIG. 3. Once filled, the inverted cap 310
can then be seated in the mouth end 302 of the container, thus both
holding product 330 for consumption and sealing the container.
Since the vendable design of the container closely approximates a
20-oz. bottle of soft drink, the container can be held in one hand
while the consumer removes product 330 from the inverted cup 310
with the other band. The container can also be placed in a typical
cup holder inside a vehicle while the consumer is consuming the
product 330 from the inverted cap 310.
[0047] Another function of the cap allows for it to be stored at
the bottom of the container. This is illustrated in FIG. 4, which
shows the cap 410 nested over the base of the container. In this
configuration, the consumer can pour product directly into the
consumer's mouth, hand, or other container without worrying about
holding the cap 410 or placing it in a location for later retrieval
and resealing of the container.
[0048] FIG. 5 illustrates another feature of one embodiment of the
invention. Specifically, three caps 509, 510, 511 are shown stacked
together to illustrate the packing efficiencies accorded by the cap
design. Specifically, a collar around the open end of the cap
(which is the only portion of the middle cap 510 exposed) provides
for easy stacking and unstacking of the caps after manufacture and
prior to installation on the receptacle. This collar promotes
automatic stacking of the cups without sticking together and
increases the hoop strength of each individual cap. Further, it is
understood that the cap can be manufactured of material and in a
manner similar to that discussed with regard to the manufacture of
the receptacle portion of the invention.
[0049] The embodiment illustrated involves a generally cylindrical
shape. However, it should be understood that the invention could
also comprise any number of shapes. For example, a triangular
geometry could be used for the receptacle in order to accommodate
stackable tortilla chips. A square or rectangular geometry could be
used to accommodate square crackers or other similar products.
Likewise, it may be desirable to construct an oval geometry for the
receptacle, as opposed to circular geometry, to more closely
approximate to the shape of form-fried and stacked potato chips.
The geometry of the cap can be adjusted to match the geometry with
the receptacle in order to provide the nesting, sealing, and
seating functionality previously described. Further, the container
could comprise other designs for the cap and mouth end of the
container, including a gabled carton type opening. Examples of
other alternative embodiments of the present invention,
illustrating primarily various container and cap designs that can
be incorporated in any number of combinations, are shown in FIGS.
6a 6b, 6c, 6d, 7a, 7b, 7c, 8a, 8b, 8c, 9a, 9b, 9c, 10a, 10b, and
10c.
[0050] A gabled carton shaped embodiment is shown in FIGS. 6a, 6b,
6c, and 6d . This container can again be comprised of a receptacle
and outer graphics layer as described previously with regard to the
alternative cylindrical embodiments. Likewise, the shape of the
container itself can be primarily square, as illustrated,
cylindrical, triangular, or any other number of shapes to
accommodate various products or promote various marketing
considerations. A variation illustrated in this embodiment,
however, is the gabled carton top 650. This top is opened by
pulling apart two tabbed sealing members 652, 654. This opening
action of pulling on the two sealing members 652, 654 is
illustrated in FIGS. 6b and 6c . Once the gabled carton top 650 is
opened, the product 630 can be poured out for consumption, as
illustrated in FIG. 6d.
[0051] FIGS. 7a, 7b, and 7c show another variation on a square
shaped container with a tear-away tab 762 which seals a cap 760 to
the top of the container. To access the product, the consumer tears
away a removable pull tab and seal portion 762 and removes the cap
760, as is illustrated in FIG. 7b. Removal of the cap 760 then
makes the product 730 available to the consumer as is illustrated
in FIG. 7c. The cap 760 in this embodiment can be snapped back onto
the container, nesting in a ridge 764 defining the opening of the
container.
[0052] FIGS. 8a, 8b, and 8c illustrate another variation on a
square shaped container that incorporates a snap-off lid 870. This
snap-off lid 870 is removed from the container by pressing upward
on an integral tab 872, as illustrated in FIG. 8b. This exposes a
seal 820, which in turn is removable by pulling back on a tab 822
component. Once both the cap 870 and seal 820 have been removed
from the container, product 830 can be dispensed from the
container, as illustrated in FIG. 8c.
[0053] FIGS. 9a. 9b, and 9c illustrate a container for holding two
types of products in separate compartments. The container 905 may
be used, for example, to conveniently hold chips and dip. The dip
is placed in the cap 910 and the chips are placed in the receptacle
915. A removable seal 920 is used to seal the dip into the integral
cap and dip container 910. Similarly, a removable seal 925 is used
to seal chips or other food product in the receptacle 915. After
the chips and dip are sealed into the main body and the cap,
respectively, the cap 910 is snapped onto the receptacle 915. An
outer layer may be placed over the container as described above in
reference to FIG. 1. The container 905 can be displayed in an
inverted position as shown in FIG. 9a to make the display more
stable since the dip in the cap 910 is heavier than the chips in
the container 915, thus resulting in a lower center of gravity than
would be the case if the container were placed in an upright
position. FIG. 9c is an illustration of the product being consumed.
The removable seals 920, 925 have been removed by the consumer and
now the cap 910 acts as a bowl from which the dip may be consumed.
The chips 930 may be consumed directly from the main body 915 or
the consumer may pour some or all of the chips out of the
container. The container may also be re-closed by the consumer to
save the unused chips and/or dip for later consumption. The nature
of the container 905 allows the packaging process to be fully
automated without the need for someone to assemble or hold the cap
on the container until an outer layer is placed around the
product.
[0054] FIGS. 10a, 10b and 10c illustrate a container for holding
multiple products in separate compartments in which a standard cup
is used. A standard cup 1005 with a removable seal 1030 is nested
in a cap 1010 and chips or another suitable food product is placed
in the receptacle 1015 and a removable seal attached to the mouth
of the receptacle 1015 to seal the food product. The standard cup
can be any container for holding consumer portions of products such
as chili cups, dip cups, cheese cups, ketchup pouches, or other
condiments or products that may be contained within said cap 1010.
The standard cup 1005 is typically limited in volume to the volume
of the cap 1010. Although this embodiment is described in terms of
a "standard cup" commonly used in the art, the invention is not
limited to the use of a standard cup. Other sub-containers may be
used with the invention herein. The dimensions of the cap 1010
should be such that the standard cup 1005 will fit into the cap
1010. Preferably, the standard cup 1005 is a slightly loose fit in
the cap 1010 so that it nests inside the cap 1010. The standard cup
1005 can also be shaped such that it can be inserted into the
receptacle 1015 in an upright position as shown in FIG. 10c. Thus,
the receptacle can hold the standard cup in the opening 1035 while
the product in the standard cup 1005 is being consumed. The
receptacle 1015 may be constructed with a curved, generally
cylindrical shape as shown in FIG. 10 to allow the container to be
easily gripped by a consumer in one hand. The shape shown in FIG.
10 is such that the container fits both large and small hands
comfortably. The receptacle can also be sized such that the
receptacle 1015 will fit in a cup holder in an automobile or
airplane, for instance, to allow ease of consumption while the
consumer is "on the go." As an example of how the container of FIG.
10 maybe utilized by a consumer, the container is opened and the
seals removed from the receptacle 1015 and the standard cup 1005.
The consumer can then pour some product (chips, for example) out of
the receptacle 1015 into the removable cap 1010. Then the standard
cup 1005 can be nested inside the opening of the receptacle 1015
and the container placed into a cup holder. The consumer then eats
the chips out of the removable cap 1010 while dipping the chips
into the dip contained in the standard cup 1005. In this manner,
the consumer can conveniently consume the chips and dip without the
need for a table on which to place the dip container.
[0055] The cap 1010 has a lip 1020 that protrudes away from the
inner wall toward the center of the cap 1010. The receptacle 1015
has a groove 1025 in the mating surface of the receptacle 1015 for
receiving the lip 1020 when the cap 1010 is placed on the
receptacle 1015. When the container is assembled, the lip 1020
engages the groove 1025 to hold the cap 1010 securely on the
receptacle 1015. The cap 1010 may be manufactured from a
polypropylene that allows the lip to stretch and the main body to
compress while the cap 1010 is "snapped" onto the main body 1015.
However, the container of the present invention is not limited to
polypropylene. Any flexible material such as a polypropylene-type
plastic may be used. The lip and groove feature of this embodiment
of the invention acts as a locking mechanism to prevent the
container from being inadvertently opened. Because of this positive
engagement, the use of an outer layer, although optional, is not
necessary to hold the container together. Although this embodiment
is described in terms of a lip and groove mating surface, this
invention is not limited to this particular type of mating surface.
Other mating surfaces may be used without departing from the scope
and spirit of the invention. The cap 1010 may also be manufactured
such that the standard cup 1005 may be seen through the cap 1010,
thus allowing a consumer to see the standard cup 1005 without
opening the container. This provides added marketing appeal to the
container.
[0056] Although not limited to any particular method of
manufacturing, the receptacle 1015 can be manufactured using an
extrusion blow molding wheel commonly known in the art. The shape
shown in FIG. 10 can be formed using a dual parrison, mouth to
mouth mold. This results in a high output, low-cost container. The
materials used in manufacturing the container should be such that
the container has effective barrier properties for the product. A
container has effective barrier properties when it maintains
product integrity under normal conditions for the designed
shelf-life of the product.
[0057] An outer layer may also be placed around the container for
additional barrier protection and decoration as described in
reference to FIG. 1. If the cap 1010 is transparent, the outer
layer should also be transparent on the bottom to allow the
standard cup 1005 to be seen through the cap 1010. When the product
is consumed, the consumer may either eat the chips or other food
product directly out of the mouth of the container 1035 or it may
be poured into the cap 1010 after the standard cup 1005 is removed.
Preferably the mouth of the receptacle 1015 is wide enough to allow
easy consumption of the product directly from the receptacle 1015.
After consuming a portion of the product, the standard cup 1005 can
be placed into the main body 1015 in an upright position as shown
in FIG. 10c. The cap 1010 is snapped back onto the container to
hold the standard cup 1005 in place and allow for convenient
storage of the container in a refrigeration unit such that the dip,
chili, or other product in the standard cup 1005 is preserved for
later consumption. This method of re-closing the container prevents
the two products from undesirably mixing together.
[0058] The embodiment shown in FIGS. 9 and 10 for a food product
combination "kit" is more portable and easier to use than prior art
combination containers. The container is ergonomically shaped to
allow it to be easily handled for people with an "on the go"
lifestyle, and yet is large enough to handle the package and access
the product while it is being consumed. The shape is also more
appealing and takes up much less shelf space than current
combination containers. The cost of producing the container
disclosed is also much lower than prior "kits" because large trays
and packaging film are eliminated.
[0059] FIG. 11 illustrates a container for holding multiple
products in separate compartments in which a pouch is used to hold
one of the products inside the cap. Although the containers
illustrated in FIGS. 9 and 10 illustrate a chip and dip
combination, the present invention is not limited to a chip and dip
combination nor is it limited to food products. Another use of the
multi-functional container, for example, is to place food product
in the receptacle 1120 of the container while placing a promotional
item such as a prize, a toy, a ball, a contest item, a collectible,
a coupon, or other non-food item inside a pouch 1130 to be held
inside the cap 1110 when the cap 1110 is mated with the receptacle
1120. Although a pouch 1130 is illustrated for holding the
promotional item, the pouch is not necessary. The promotional item
can also be placed directly inside the cap 1110 without a pouch or
covering. The advantage of placing the promotional item 1130 in the
cap rather than in the receptacle 1120 of the container along with
the food product is that the food product is kept out of direct or
indirect contact with the promotional item 1130 by the membrane or
seal 1140 on the receptacle 1120. Thus, any concerns about
contamination of the food product by the promotional item 1130 are
alleviated. This reduces the cost of compliance with federal
regulations regarding items in direct or indirect contact with food
products. Prior art containers having promotional items inside the
container have placed them either in direct or indirect contact
with the food product. The present invention, however, allows the
promotional pieces to be placed inside a portable container while
keeping the promotional pieces separated from the food product.
Furthermore, the present invention allows the volume of the food
product in the main body of the container to remain unchanged
during a promotional campaign. In prior designs, either the volume
of the product must be reduced, or the container size must be
increased when a promotional piece is inserted to maintain the same
volume of product.
[0060] Although the container in FIG. 11 illustrates a single prize
being placed inside the cap 1110, the invention is not limited to a
single cap or a single prize, nor is the particular shape of the
cap limited to that shown. In another embodiment, two caps could be
placed on each end with food products and/or promotional items in
each cap, or a cap can be placed on one end and a molded prize
attached to the other end. For example, in addition to placing a
prize or food product inside the cap 1110, another prize that is
molded to fit the base of the receptacle 1120 could be removably
attached directly to the bottom of the container to form part of
the overall shape of the container. This prize could be, for
example, an injection molded stencil toy that could be removed by a
consumer and a picture drawn by the consumer marking through the
stencil onto a piece of paper. In such an embodiment, the
portability of the container is maintained while also keeping the
food product separate from the promotional items.
[0061] It should be understood that all of the alternative
container embodiments discussed above can incorporate a
multi-functional cap with a shape to accommodate the overall
container shape. For example, a multi-functional cap could be used
with the square container shapes illustrated in FIGS. 7a and 8a,
wherein the cap would have a similar square shape in order to nest
over the mouth of the container, seat in the mouth of the container
when inverted, and nest for storage over the bottom of the
container. Further, the discussion of specific container shapes and
cap designs is not limiting on the invention, which focuses on the
goal of a simple design with maximum utility for the consumer. For
example, more than one or two compartments can be provided in the
container for multiple products. The container could be
double-ended with caps on both ends of the container to add even
more utility.
[0062] While the invention has been particularly shown and
described with reference to a preferred embodiment, it will be
understood by those skilled in the art that various changes in form
and detail may be made therein without departing from the spirit
and scope of the invention.
