Abstract
A canister for containing a particulate-type product such as a ready-to-eat cereal. The canister includes a side wall, a bottom closure and a plastic lid. The side wall defines at least a portion of a tubular body having an upper opening, a lower opening and an internal storage region for containing the particulate-type product. In this regard, the side wall includes a first, paper-based layer and a second, plastic-based layer. The first, paper-based layer has an inner surface and an outer surface. The second, plastic-based layer is bonded to the inner surface of the first, paper-based layer. The bottom closure is connected to the side wall so as to encompass the bottom opening. The plastic lid is openably secure to the tubular body at the upper opening. In this regard, the plastic lid provides selective access to the internal storage region. With this configuration, the plastic lid facilitates rapid fabrication of the canister, as well as providing for increased canister durability.
Description




BACKGROUND OF THE INVENTION




The present invention relates generally to a canister for containing a particulate-type product. More particularly, the present invention relates to a paper and plastic formed canister including a plastic lid that contains a particulate-type product, such as a ready-to-eat cereal food product therein.




An extremely popular form of packaging for dry, particulate-type products sold to consumers is a paper carton. The paper carton normally is rectangular-shaped, constructed of one or more layers of paper (such as label stock or paperboard having printing on an outer surface), and may or may not include an inner plastic liner. A wide variety of different products are packaged in this form, ranging from consumable items such as ready-to-eat (RTE) cereals and baking goods to non-consumable items such as laundry detergents and de-icing salt pellets.




Paper cartons present a number of advantages for manufacturers, retailers, and consumers. For example, paper cartons are relatively inexpensive to manufacture and provide a number of flat surfaces onto which product or promotional information can be displayed. Due to the rectangular, parallel-piped shape, the cartons are relatively rigid and readily stackable. Thus, a manufacturer can ship a large number of stacked cartons without experiencing product damage. Further, a retailer can maximize shelf space while fully displaying the product. Consumers likewise find the stackability characteristic desirable for home storage. Finally, paper cartons can be sized in accordance with consumer product volume preferences.




Certain types of products are amenable to storage within a paper carton alone. Generally speaking, however, a paper carton cannot, in and of itself, adequately maintain product integrity. For example, a paper carton likely will not prevent aroma, moisture, contaminants, small insects, etc., from passing through to the contained product. Thus, packaging for most particulate-type products requires an additional container or bag disposed within the paper carton. This is especially true for consumable/food products. A widely accepted technique for maintaining product integrity is to place the product into an inner container or bag that in turn is stored within the carton (commonly referred to as “bag in a box” technique). The bag is typically made of a plastic or glassine material and is sealed about the product. In this sealed form, the bag maintains product freshness and provides protection against contamination or insect infestation, whereas the outer paper carton provides packaging strength and display. Alternatively, a double packaging machine (DPM) technique may be employed to form a plastic or glassine liner within the paper carton. Regardless of the exact manufacturing process, the resulting packaging configuration includes a box with an inner liner. The box is a single layer paperboard or label stock material that provides structural integrity, whereas the separate inner liner serves as a barrier material.




The box with an inner liner packaging approach is universally employed. In fact, from a manufacturer's standpoint, box with an inner liner packaging satisfies a number of important criteria including low cost, stackability, and large, flat surfaces for displaying product and promotional information. Unfortunately, however, consumers may encounter several potential drawbacks with this packaging approach. For example, difficulties may be encountered when attempting to open the paper carton and/or the inner bag. To this end, one or both of the paper carton and plastic bag can be inadvertently torn. Once opened, the flexible nature of the inner bag makes it difficult to establish a consistent opening for uniform product flow. Finally, it is often times difficult to sufficiently re-close both the inner bag and the paper carton in a manner that prevents unexpected product displacement and/or contamination.




To overcome the above concerns, a canister configuration has been contemplated. For example, rigid plastic canisters having removable, sealable lids are available. The greatly increased cost associated with this packaging configuration prohibits its implementation on a mass production basis. Alternatively, baking flour has been commercially sold in a wax-coated paper carton to which an elongated plastic lid is attached. Unfortunately, packaging strength and barriers to contamination are limited, and the lid configuration does not promote uniform product flow upon removal. While not currently available, a more satisfactory approach may be the formation of a canister having wall(s) comprised of an inner plastic ply or layer bonded to one or more outer paper plies or layers. This novel technique may resolve several deficiencies associated with the traditional box with inner liner packaging, and presents opportunities for further manufacturing and performance enhancements. For example, the formed, combination paper and plastic nature of the canister may allow for a lid/closure structure that does not rely upon a folded paper tab or rolled bag utilized with paper cartons. In addition to solving opening and closing problems, the canister may have improved durability. Further, the canister and lid can be configured to promote simple, rapid assembly with mass production.




Consumers continue to express a high demand for particulate-type products, such as ready-to-eat cereal products, sold in paper cartons. However, various problems associated with standard packaging, and in particular box with an inner liner packages, may diminish purchasing enthusiasm. In fact, any efforts to satisfy consumer preferences on a cost effective basis while maintaining the beneficial properties of current packaging will likely result in heightened sales. In this regard, new canister packaging configurations may present distinct opportunities for lid enhancements. Therefore, a need exists for a paper and plastic container including an improved lid configuration.




SUMMARY OF THE INVENTION




One aspect of the present invention provides a canister for a particulate-type product. The canister includes a side wall, a bottom closure and a plastic lid. The side wall forms at least a portion of a tubular body defining an upper opening, a lower opening and an internal storage region for containing a particulate-type product. In this regard, the side wall includes a first, paper-based layer and a second, plastic-based layer. The first layer has an inner surface and an outer surface. The second layer is bonded to the inner surface of the first layer. The bottom closure encompasses the lower opening. Finally, the plastic lid is openably secured to the tubular body at the upper opening, and is configured to provide selective access to the internal storage region. With this configuration, the plastic lid facilitates ease of manufacture and enhances overall canister durability. Further, in one preferred embodiment, the plastic lid includes a flap pivotably secured to a body portion that in turn is attached to the side wall. During use, the flap is maneuvered to an opened position for providing access to the internal storage region.




Another aspect of the present invention relates to a packaged good article. The packaged good article includes a canister and a particulate-type product. The canister includes a side wall, a bottom closure and a plastic lid. The side wall forms at least a portion of a tubular body defining an upper opening, a lower opening and an internal storage region. With this in mind, the side wall includes a first, paper-based layer and a second, plastic-based layer. The first layer includes an inner surface and an outer surface. The second layer is bonded to the inner surface of the first layer. The bottom closure encompasses the lower opening. The plastic lid is openably secured to the tubular body at the upper opening. Finally, the particulate-product is contained within the internal storage region. In one preferred embodiment, the particulate-type product is a dried food product, such as a ready-to-eat cereal.




Yet another aspect of the present invention relates to a method of manufacturing a canister for containing a particulate-type product. The method includes providing a first, paper-based layer having an inner surface and an outer surface. A second, plastic-based layer is also provided. The second, plastic-based layer is bonded to the inner surface of the first, paper-based layer. The bonded first and second layers are formed into a tubular body having an upper opening and a lower opening. The lower opening is encompassed with a bottom closure. A plastic lid is provided. The plastic lid is openably secured to the tubular body at the upper opening. With this configuration, the tubular body defines an internal storage region for containing a particulate-type product. The use of a plastic lid facilitates manufacture of the canister and results in a canister with increased durability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




One preferred embodiment of a canister


10


is shown in FIG.


1


. The canister


10


includes a side wall


12


preferably defining opposing face panels


14


(one of which is shown in

FIG. 1

) and opposing side panels


16


(one of which is shown in FIG.


1


), a bottom panel or closure


18


(referenced generally in FIG.


1


), and a lid


20


. As used throughout this specification, directional terminology such as “bottom,” “top,” “upper,” “lower,” etc., is used for purposes of illustration and with reference to a desired upright orientation of the canister


10


as shown in FIG.


1


. However, the canister


10


can be positioned in other orientations such that directional terminology is in no way limiting.




As described in greater detail below, the side wall


12


is preferably continuous, forming at least a portion of, preferably an entirety of, a tubular body


22


that defines the opposing face panels


14


and the opposing side panels


16


. Thus, the term “side wall” as used throughout the specification is in reference to one or more of the opposing face panels


14


and/or the opposing side panels


16


. It should be understood, however, that the opposing face panels


14


and the opposing side panels


16


can be separately formed and assembled. Even further, the side wall


12


, and thus the tubular body


22


, need not necessarily assume the generally rectangular configuration shown in FIG.


1


. For example, the canister


10


can be circular in cross-section, such that the side wall


12


, and thus the tubular body


22


, is formed to be cylindrical, frusto-conical, etc. With these alternative shapes, distinct or distinguishable face and side panels will not be formed.




The bottom panel


18


is connected to the tubular body


22


at a lower portion thereof. Similarly, the lid


20


is connected to the tubular body


22


at an upper portion thereof This configuration provides an internal storage region


24


(shown partially in

FIG. 1

) within which a particulate-type product


26


is disposed. In one preferred embodiment, and as described in greater detail below, the particulate-type product


26


can be dispensed from the internal storage region


24


by opening a hinged flap


28


formed by the lid


20


. Alternatively, the lid


20


can be entirely removable from the tubular body


22


.




The side wall


12


is comprised of at least two layers, as shown in FIG.


2


. As a point of reference, the cross-sectional view of

FIG. 2

depicts a portion of the side wall


12


, such as a portion one of the opposing face panels


14


(

FIG. 1

) and/or the opposing side panels


16


(FIG.


1


). In a preferred embodiment, the side wall


12


is continuous in forming the tubular body


22


(FIG.


1


), such that each of the opposing face panels


14


and the opposing side panels


16


are similarly constructed. Alternatively, as few as one of the opposing face panels


14


or the opposing side panels


16


need have the construction illustrated in FIG.


2


. With the above in mind, the side wall


12


includes a first, paper-based layer


30


and a second, plastic-based layer


32


.




The first, paper-based layer


30


defines an inner surface


40


and an outer surface


42


, and is preferably a label stock paper material being 14-point or less in thickness. Label stock material is readily available and is highly amenable to printing on the outer surface


42


. Printing onto label stock paper material is well-known in the art and may include product information, promotional statements, etc. To minimize overall costs, the label stock paper material is preferably formed from recycled paper. Alternatively, the first, paper-based layer


30


can have other thicknesses and can be paperboard.




The second, plastic-based layer


32


defines an inner surface


44


and an outer surface


46


, and provides a functional or contamination barrier to at least one of flavor, aroma, moisture, oil, grease, other contaminants, insects, etc. As a point of reference, the inner surface


44


is the inner surface of the canister


10


(FIG.


1


). The selected plastic for the second layer


32


must be suitable for contact with the particulate-type product


26


(FIG.


1


). For example, where the particulate-type product


26


is a food product, the selected plastic material must be approved for food contact, as is well-known in the art. Thus, for example, the plastic material can be polyethylene (low density or high density), chlorinated plastic, ethylene vinyl acetate, polyester, nylon, polypropylene, etc. Even further, the plastic material can be various co-polymers, blends, or a combination of plastic materials. In one preferred embodiment, the second layer


32


is a combination of at least two plastic materials, with one plastic material serving as a barrier portion and the other as a sealant portion. Basically, the sealant portion has a lower melt point than the barrier portion such that upon application of heat and pressure, the sealant portion melts and laminates to the inner surface


40


of the first, paper-based layer


30


. For example, the second layer


32


can include a polyethylene barrier portion and an ethylene vinyl acetate resin forming the sealant portion. Alternatively, other lamination or bonding techniques can be employed, such as use of an adhesive.




While the side wall


12


has been described as been described with reference to two layers


30


,


32


, additional layer can be provided. For example,

FIG. 3

provides a cross-sectional view of a more preferred alternative side wall


60


. The side wall


60


includes the first, paper-based layer


30


, and the second, plastic-based layer


32


. In addition, the side wall


60


includes a third layer


62


and an adhesive


64


. The third layer


62


is preferably paper-based and defines an inner surface


66


and an outer surface


68


. The inner surface


66


is bonded to the outer surface


42


of the first, paper-based layer


30


by the adhesive


64


.




With the side wall


60


, the first-paper based layer


30


is a paper board or liner board material, such as 42-pound liner board, and is laminated to the second, plastic-based layer


32


as previously described.




The third layer


62


is also a paper-based material, but is preferably label stock being 14-point or less in thickness. As previously described, label stock material is readily available and is highly amenable to printing on the outer surface


68


. By providing two different thicknesses for the first layer


30


and the third layer


62


, overall costs of the resulting side wall


60


are minimized. In other words, use of a single, thick layer of non-recycled paper inherently increases costs. It should be noted, however, that the first layer


30


and the third layer


62


can alternatively be identical in thickness and composition.




The adhesive


64


is preferably a cold adhesive. For example, the adhesive


64


can be polyvinyl alcohol, polyvinyl acetate, casein, starch, etc. Even further, the cold adhesive can be various blends or combinations of acceptable cold adhesive materials and/or other materials such as activators. Alternatively, the adhesive


64


can be a hot-melt adhesive, such as a polyethylene-based material with tackifiers and wax, a polypropylene-based material with tackifiers and wax, a polyester-based material with tackifiers and wax, etc. Even further, the hot-melt adhesive can be various co-polymers, blends, or a combination of acceptable adhesive materials and/or other materials such as activators. Notably, cold adhesives are generally less expensive than hot-melt adhesives and typically require a reduced volume to achieve an appropriate bond. Further, cold adhesives generally do not produce an adverse, “adhesive-like” odor that might otherwise adversely affect quality of the particulate-type product


26


(

FIG. 1

) contained within the canister (FIG.


1


). The adhesive


64


can be applied in a wide variety of fashions, including flood coating or pattern application.




The lid


20


is depicted in greater detail in FIG.


4


. The lid


20


includes a body portion


80


, the flap


28


and a skirt


82


. The flap


28


is pivotably secured to the body portion


80


along a hinge line


84


such that the flap


28


is moveable relative to the body portion


80


from a closed position (

FIG. 1

) to an open position (FIG.


4


). The skirt


82


extends downwardly from, and defines a perimeter of, the body portion


80


and the flap


28


.




The lid


20


is configured to be secured to the tubular body


22


, and is therefore sized and shaped in accordance with a size and shape of the tubular body


22


. For example, the lid


20


can assume the elongated, generally rectangular shape of FIG.


4


. To facilitate assembly with the tubular body


22


, the skirt


82


is preferably sized to be frictionally received within the tubular body


22


. Alternatively, the skirt


82


can form a lip configured to extend over and frictionally engage a leading edge


85


of the tubular body


22


. Preferably, however, construction of the skirt


82


is such that snap-fit is achieved between at least a portion of the lid


20


and the tubular body


22


. To this end, a first section


86


of the skirt


82


(associated with the body portion


80


) can be sized to achieve a more permanent attachment to the leading edge


85


of the tubular body


22


, whereas a second section


88


(associated with the flap


28


) is more easily detachable therefrom. Even further, an additional structure may be provided to more permanently secure the body portion


80


, such as an adhesive, tape, etc.




As previously described the flap


28


is movable relative to the body portion


80


along the hinge line


84


to provide selective access to the internal storage region


24


upon final assembly. This feature can be achieved with a number of other configurations for the lid


20


. For example, the lid


20


can be a uniform, relatively rigid body that is entirely securable to, and removable from, the tubular body


22


. Alternatively, the flap


28


can be separate from the body portion


80


such that the flap


28


is completely detached from both the tubular body


22


and the body portion


80


during use. Even further, the flap


28


can form a spout or other structure designed to promote product flow.




Regardless of exact form, the lid


20


, including the body portion


80


, the flap


28


and the skirt


82


, is preferably integrally formed from a rigid, plastic material. The plastic material selected for the lid


20


must be approved for use with the particulate-type product


26


and is preferably compatible with the material selected for the second, plastic-based layer


32


(FIG.


2


). For example, where the particulate-type product


26


is a food product, the plastic material selected for the lid


20


can be polyethylene (low or high density), chlorinated plastic, ethylene vinyl acetate, polyester, nylon, polypropylene, polycarbonate, polyvinyl chloride, etc. Other acceptable materials include polystyrene, ethylene vinyl alcohol, etc. Even further, the plastic material can be various co-polymers, blends, or a combination of plastic materials.




By forming the lid


20


from a plastic material, as well as the side wall


12


and the bottom panel


18


to include a plastic-based layer (such as the second, plastic-based layer


32


of FIG.


2


), a relatively sealed environment can be established for the canister


10


. To minimize the potentially adverse effects of atmospheric pressure changes experienced by the canister


10


, in one preferred embodiment, the lid


20


forms a plurality of minute air vent holes


89


(greatly exaggerated in

FIG. 4

for purposes of illustration). While extremely small in diameter (on the order of 10-100 micrometers), the air holes


89


allow airflow into and out of the internal storage region


24


that is otherwise essentially hermetically sealed. Thus, the air holes


89


provide for venting of air from the internal storage region


24


upon a decrease in atmospheric or barometric pressure acting upon an exterior of the canister


10


, thereby preventing potentially damaging swelling of the canister


10


.




In one preferred embodiment, to enhance a perception of product freshness and to provide an indication of product tampering, the canister


10


can further include a membrane


90


as shown in FIG.


5


. For ease of illustration, the canister


10


is depicted in

FIG. 5

with the flap


28


(

FIG. 4

) removed. The membrane


90


is preferably positioned beneath the lid


20


, and in particular the flap


28


, and extends across an upper opening


92


in the tubular body


22


along the leading edge


85


. The membrane


90


is preferably a thin layer comprised of plastic, paper or a combination thereof. To facilitate removal of at least a portion of the membrane


90


, the membrane


90


is preferably formed to include perforations


94


. The perforations


94


can be imparted via any known manufacturing technique and can assume a wide variety of forms. Additionally, the membrane


90


can include indicia


96


configured to provide visual instructions to a user proper membrane removal, such as words, symbols or illustrations. Regardless, the membrane


90


is either partially or completely removed to expose the upper opening


92


.




Assembly of the canister


10


begins with formation of the side wall


12


, such as by laminating the second, plastic-based layer


32


(

FIG. 2

) to the first, paper-based layer


30


(FIG.


2


). Once formed, the side wall


12


is cut to an appropriate size. The opposing face panels


14


and the opposing side panels


16


are then formed from, for example as illustrated in FIG.


6


. In one preferred embodiment, the side wall


12


is wrapped about a mandrel


100


. Opposing edges of the side wall


12


are connected to form a seal


102


. The seal


102


can be a butt seal as shown, but alternatively can be an overlapped seal, fin seal, etc. Notably, the layers


30


,


32


can alternatively be staggered or rotated 180 degrees from one another. As shown in

FIG. 6

, in the sealed configuration, the side wall


12


defines and integrally forms the opposing face panels


14


and the opposing side panels


16


. Notably, with the mandrel fabrication technique, corners


104


formed by the opposing face panels


14


and the opposing side panels


16


are preferably rounded or arcuate, but instead can be angular. Alternatively, the opposing face panels


14


and the opposing side panels


16


can be independently formed and subsequently connected, preferably sealed, to one another. Even further, as previously described, the mandrel


100


can be circular in cross-section such that only a single, continuous panel is formed. Regardless, following formation of the seal, the side wall


12


forms the tubular body


22


.




A remainder of the canister


10


is then constructed as shown in FIG.


7


. Once formed, the tubular body


22


includes the upper opening


92


(referenced generally in

FIG. 7

) and a lower opening


110


(referenced generally in FIG.


7


). The lid


20


is then connected to the tubular body


22


so as to encompass the upper opening


92


. Notably, by forming the lid


20


from a plastic material, assembly to the tubular body


22


can be performed in a rapid fashion unlike prior paper-based lids/packages. As previously described, at least a portion of the lid


20


is selectively secured to the tubular body


22


(such as the flap


28


). The particulate-type product


26


is then placed within the internal storage region


24


(

FIG. 1

) defined by the tubular body


22


. Finally, the bottom closure


18


is connected to the tubular body


22


so as to encompass the lower opening


110


. The bottom closure


18


is preferably a panel that includes laminated paper and plastic layers as previously described with reference to the side wall


12


. Alternatively, the lower opening


110


can simply be sealed closed. While construction of the canister


10


has been described as preferably including placement of the lid


20


and then the bottom closure


18


, this order can be reversed. Further, other enhancement features, such as a tamper evident tape/seal secured across at least a portion of the seam between the lid


20


and the tubular body


22


, can be incorporated.




By preferably forming the side wall


12


and the bottom closure


18


from the first paper-based layer


30


(

FIG. 2

) and the second, plastic-based layer


32


(FIG.


2


), and the lid


20


from a plastic material, the canister


10


is sealable and provides a functional barrier to at least one of flavor, aroma, moisture, oil, grease, insects, or other contaminates. Thus, the canister


10


can be used to maintain a wide variety of particulate-type products. For example, the particulate-type product


26


can be a food product, and in particular, a dried food product. One specific category of available food products is cereal-based products (e.g., formed from wheat, oats, rice, etc.). These include ready-to-eat cereals, such as puffs, flakes, shreds, and combinations thereof. Further, the ready-to-eat cereal product can include other ingredients, such as dried fruits, nuts, dried marshmallows, sugar coatings, etc. Alternatively, other particulate-type dried food products can be maintained by the canister


10


, such as, for example, popcorn (popped or un-popped), dried pasta (e.g., spaghetti noodles), rice, beans, pretzels, potato chips, sugar, dried milk, flour, etc. Even further, other consumable items, such as birdseed, can constitute the particulate-type product


26


. Yet even further, non-consumable particulate-type products, including fertilizer pellets, dry laundry detergent, dry dishwashing detergent, plants or vegetable seeds, de-icing salt pellets, etc., can be stored within the canister


10


. Regardless of the exact product constituting the particulate-type product


26


, the combination paper and plastic side wall


12


in conjunction with the plastic lid


20


allows the canister


10


to maintain the integrity of the particulate-type product


26


independent of any additional liners or bags.




Upon final assembly, the canister


10


is available for shipment and commercial sale. In this regard, the relatively rigid nature of the lid


20


enhances the overall durability of the canister


10


. That is to say, unlike currently available paper cartons, the plastic lid


20


reinforces the canister


10


against transverse and/or lateral forces commonly encountered during shipping. Following purchase, a consumer (not shown) gains access to the particulate-type product


26


by opening the lid


20


as shown in FIG.


8


. As previously described, at least a portion of the lid


20


, such as the flap


28


, is openable relative to the tubular body


22


, thereby providing a pour opening


112


through which the particulate-type product


26


can be dispensed from the canister


10


. For example, the flap


28


can be pivoted relative to the body portion


80


. With this one preferred embodiment, by forming the lid


20


from a plastic material, a relatively rigid frictional engagement of the flap


28


relative to the body portion


80


in the open position can be established, thereby enhancing product dispensement and consumer satisfaction.




Following dispensement of a desired volume of product, the canister


10


can effectively be “re-sealed” by closing the lid


20


. With reference to the one preferred embodiment, the flap


28


is maneuvered from the open position shown in

FIG. 8

to the closed position of FIG.


1


. In this regard, by forming the lid

to air, moisture, contaminants, etc.




The canister of the present invention provides a marked improvement over previous designs. In particular, by forming the main body portion of the canister from a combination of paper and plastic materials, as well as providing a plastic lid, a durable, relatively sealed package is formed. In addition, the plastic lid is easily assembled to the canister body, can more readily maintain an open position, and can provide an audible indication of proper closure.




Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the present invention. For example, the canister has been depicted as being generally rectangular in shape. Alternatively, other shapes are equally acceptable. Also, the canister can contain items in addition to the particulate-type product. For example, a separate coupon or premium can be placed within the canister along with the particulate-type product.
