Abstract

Coaxial and non-coaxial ingredient packages provides an integrated inner and outer package via a common transverse seal across opposing ends of the package. The transverse seal is accomplished by way of the outer surface of the inner package and the inner surface of the outer package. The inner package functions to receive a first ingredient and the outer package functions to receive a second ingredient. An opening mechanism located at a select package end enables the user to unseal the inner and outer packages simultaneously thereby facilitating the common dispensing of package contents or ingredients in a complementary manner for opportune admixture. Certain methodology for coaxial ingredient or foodstuff service and/or presentation is further presented as reflective of the disclosed structures.

Description

Field

The present disclosure generally relates to an ingredient or foodstuff package having distinct ingredient or foodstuff compartments, and in particular to an ingredient package which functions to package and dispense plural ingredients or foodstuffs therefrom.

Background

Gasified candy, when exposed to moisture, tends to melt when in prolonged contact therewith. Given a sufficient amount of exposure to moisture (as for example, when exposed to one's mouth), the candy shells surrounding carbon dioxide gas bubbles essentially melt thereby releasing carbon dioxide gas, which action is often described as a popping sensation in one's mouth. The candy, to have its intended affect, should preferably be melted at the time of consumption and therefore separated from ingredients that may tend to otherwise prematurely melt the candy shells and release the popping gas. The candy, however, is often times enjoyed in conjunction with other food items or foodstuffs having significant moisture content such as pudding. In order to successfully serve both pudding and gasified candy for simultaneous consumption, it is necessary to separate the two ingredients prior to consumption. Packaging that enables the consumer to simultaneously and conveniently carry both ingredients in a single package for simultaneous consumption and enjoyment is therefore desirous.
Gasified candy and pudding are exemplary ingredients, however. Other foodstuffs or ingredients that may benefit from compartmentalized separation prior to consumption include any number of probiotic products and/or products containing active cultures such as yogurt or cottage cheese juxtaposed against other sugary ingredients or foodstuffs such as fruit, fruit-based ingredients, jams, and jellies. Some of the more pertinent prior art relating to packaging directed to compartmentalizing ingredients or constituent parts prior to active admixture and the like is described hereinafter.
United States Patent No. 3,861,522 ('522 Patent), which issued to Llewellyn et al., discloses a Compartmented Package having Variable Volume Compartments. The '522 Patent teaches a compartmented package in which a longitudinal diaphragm, made of film, is sealed to the inner wall of a circular tubular member, also made of film, to form at least two continuous longitudinal linear junctures therebetween in a manner such that the volumes of the resulting compartments are variable. A two-compartment package having infinite relative volume variability in both compartments is stated to be the preferred embodiment.
United States Patent No. 4,495,748 ('748 Patent), which issued to Rowell, discloses certain Containers and Machine for Making Them. The '748 Patent teaches a container preferably made from sheet plastics comprising a bag containing a tubular valve member, the bag being sealed with a seam at each end, the top seal having an opening therein for entry of an access tube into the valve member, and the valve member having a sealing seam which facilitates piercing of the access tube through the valve member into the bag. A second bag may be provided within the first bag. A machine for making the containers continuously from sheets of material is also disclosed.
United States Patent No. 4,681,228 ('228 Patent), which issued to Kerry et al., discloses a Package Filled with a Water Soluble Toxic Pulverulent or Granular Product. Kerry et al. note that some chemical products are so toxic that they must not come into contact with parts of the human body. The '228 Patent teaches a package of such a construction that during filling and transport thereof and during the release of product therefrom, the risk of anyone coming into contact with the product is restricted to a minimum, is characterized in that the product is situated in a closed inner container consisting of a water-soluble flexible material, and that the filled inner container is placed inside a closed outer container consisting of a flexible material which is resistant to water, both the inner container and the outer container consisting of a flexible tube which is closed near the two ends by a transverse joint and the end strips of the inner container are connected to the joining strips of the outer container in a manner such that between the contents of the inner container and the said joining strips there is a certain distance, and that a tear line is made in an exposed part of one of the end strips of the inner container.
United States Patent No. 6,935,086 ('086 Patent), which issued to Benkus et al., discloses a double-bag package, and method for manufacturing the same, constructed by modification to existing Double Bag Package and Perforation Knife. The '086 Patent teaches certain form and fill packaging machines and perforation knives. In a preferred embodiment thereof, the disclosure involves producing a double-bag package from a single sheet of packaging film by feeding a roll of film having graphics printed sideways rather than vertically into a vertical form, fill and seal packaging machine and using a novel perforating/cutting knife to alternately cut and perforate transverse seals. The perforating/cutting knife has teeth in the shape of oblique triangular pyramids, with each tooth having three cutting edges. The perforating/cutting knife produces self-correcting T-shaped perforation patterns capable of capturing and redirecting errant tears for fail-safe directional separation.
International Publication No. WO 94/27886 , authored by Richter et al., discloses a Container with Multiple Chambers, to Package Components Separately Prior to Use in Admixture. The Richter et al. publication teaches a package for accommodating a product having at least two components, which package has at least two self-contained chambers in which the individual components of the product can be stored in such a manner that they are hermetically separated from one another. The individual chambers are connected together in such a manner that they can be separated from one another only by destroying at least one chamber wall. The end regions of the chamber walls are in the form of a common closure for the individual chambers such that the individual chambers can only be opened simultaneously. In the preferred embodiment, the package comprises at least one folded carton having essentially a front and a back wall, side walls, bottom flaps and top flaps, inside which carton are arranged in a fixed manner at least two tube-like inner sachets each of which accommodates one of the components directly and which represent the chambers for the individual components, and the top end regions of which that project out of the inside of the folded carton form the common closure after the inner sachets have been filled separately.
WO2006/127186 discloses a flexible package for a liquid-based food item and a packaged liquid-based food item, such as a soup. A flexible package or pouch includes an outer member or pouch and an inner dividing member or pouch that is disposed or positioned inside the outer member to define inner and outer cavities. As can be seen from, for example, Figures 1 to 6 of WO2006/1271 the inner and outer cavities are coaxially aligned. A liquid, such as water or broth, and one or more seasonings are placed in the inner cavity. Particulates, such as meat and vegetable particulates and, if necessary, water, are placed in the outer cavity. Seasonings are separated from particulates, and the seasoning does not diffuse into the particulates. Thus, the tastes of the individual ingredients are maintained. A sealing member extends across a tops of the inner and outer members to close the package. When the sealing member is removed to open the package, the water or broth with the seasoning, and the particulates and any water can be poured from their respective cavities in a single motion. By reducing or eliminating diffusion of seasonings into particulates, reduced quantities of salt and other seasonings can be added to processed soup products and allows salt and other seasonings to be added just prior to cooking, providing more natural flavor. Separating broth and particulates within a container can also reduce sterilization times.
US2003/172624 provides a vertical stand-up pouch or flexible package, and method for manufacturing same, constructed by modification to existing vertical form and fill packaging machines. The method involves producing a vertical stand-up pouch from a single sheet of packaging film by creating a vertical crease along one edge of a packaging film tube
prior to forming a transverse seal on the tube. The vertical crease is formed using a stationary tucker bar positioned outside the packaging film tube and between two forming plates positioned inside the packaging film tube.
FR1252916 discloses a packaging system which comprises two sheaths formed of polyethylene or another flexible plastic. One of the sheaths is placed inside the other and the ends of the sheaths may be closed independently of each other. The corresponding end of the outer sheath is closed around the walls of the inner sheath. The two sheaths delimit two chambers, namely an internal chamber delimited by the single inner sheath and an outer chamber delimited by the inner sheath and the outer sheath.
FR 2696995 provides a package for liquid, powdered or paste products which comprises two containers, one within the other, with each containing a different product. The package is prepared by taking a sheet of heat sealable material and unrolling it, flattening it, and folding it along longitudinal line to form two overlapping sections. The sheet is then sealed along the free edges to form a primary tube which is sealed transversely. The primary tube is then inserted within a second tube of larger transverse dimensions. The second tube is then heat sealed at predetermined intervals opposite the seal of the inner container to form a series of concentric inner and outer containers. The containers are filled and then cut along the seals to form individual packages. Opening of one of the packages results in the automatic opening of both tubes resulting in instant mixing where required.
US1639699 discloses an article of manufacture comprising a pair of concentrically disposed collapsible tubes containing a plurality of viscous bodies. The mobility of the inner body is sufficiently less than the mobility of the outer body so as to cause both bodies, when pressure is applied, to be extruded from said tubes at the same speed.
US3255872 provides a package comprising a container including an outer pouch and an inner pouch, the inner pouch being disposed within the outer pouch. The inner pouch has opposite ends thereof secured to respective ends of the outer pouch. Different materials are contained in the inner and outer pouches and the relative proportions of the length, elongation and strength of material of the inner pouch are substantially less than the relative proportions of length, elongation and strength of material of the outer pouch such that when endwise tension is applied to the container, the inner pouch will rupture and the contents of the inner pouch may be disposed directly within the outer pouch.
From a review of these publications and other prior art generally known in the relevant art, it will be seen that the prior art does not teach a package for coaxially aligning and compartmentalizing constituent ingredients of a final mixture. Further, the prior art does not teach certain methodology for finally serving foodstuffs or presenting ingredients by axial displacement relative to package assembly, whereby plural foodstuffs or ingredients are coaxially presented for mixture at the time of consumption. The prior art thus perceives a need for a package assembly and methodology associated therewith that provides consumers with a novel means for receiving and consuming multiple ingredients, the admixture of which has arguably greater delectable value than the sum of its parts.

Summary

Accordingly, an ingredient separating package is disclosed which functions to package and present plural ingredients which may, upon presentation, effect an opportune admixture.
In one aspect, the coaxial foodstuff package for packaging plural foodstuffs in distinct coaxial compartments
compris es at least one inner foodstuff barrier, wherein the inner foodstuff barrier includes a longitudinal lap seal; an outer foodstuff barrier, wherein the outer foodstuff barrier includes a longitudinal fin seal; first and second foodstuff package ends; and a longitudinal package axis; the inner foodstuff barrier receiving an inner foodstuff thus forming an inner food package, the longitudinal lap seal of the inner foodstuff barrier for minimizing package material volume intermediate the inner and outer foodstuff barriers and, the outer foodstuff barrier receiving the inner food package and an outer foodstuff in substantially coaxial relation about the package axis, the inner foodstuff barrier preventing contact intermediate the inner and outer foodstuffs, the outer foodstuff barrier preventing contact intermediate the outer foodstuff and radially ambient matter, the longitudinal fin seal of the outer foodstuff barrier for maximizing seal integrity, and the first and second foodstuff package ends being sealed for selectively preventing contact intermediate the inner and outer foodstuffs and axially ambient matter.
The inner and outer tubes may be sealed to one another at the first and second package ends and may comprise certain manually enabled, end-opening structure as may be preferably defined by state of the art singular, paired, continuous, or skipped laser scoring. Thereby, the user may selectively unseal or open a select package end (typically the top package end as directed by external graphical indicia) and coaxially dispense the inner and outer ingredients for further effect or action. Certain methodology is further presented as reflective of the disclosed structures in terms of coaxial ingredient presentation and foodstuff service.
According to a further aspect of the present invention, there is provided a foodstuff service method for serving mixable foodstuffs to a foodstuff consumer, the method comprising the steps of aligning an inner foodstuff about a foodstuff axis by packaging the inner foodstuff within a first foodstuff barrier sealed with a longitudinal lap seal; coaxially aligning at least one outer foodstuff about the inner foodstuff by packaging the at least one outer foodstuff within a second foodstuff barrier coaxially about the first foodstuff barrier where the second foodstuff barrier is sealed with a longitudinal fin seal; sealing the inner and outer foodstuffs from ambient matter prior to serving the foodstuffs; opening the inner and outer foodstuffs to ambient matter for serving the foodstuffs; and serving the inner and outer foodstuffs.

Detailed Description

Referring now to the drawings with more specificity, an embodiment of a coaxial ingredient or foodstuff package or coaxial package assembly 10 is generally illustrated and referenced in Figure Nos. 1- 5, 14, and 16.
The coaxial package assembly 10 is designed primarily for compartmentalizing and packaging ingredients or foodstuffs in coaxial relation to one another and for presenting the coaxially aligned ingredients or foodstuffs to the consumer. The non-coaxial package assembly 102 is designed primarily for compartmentalizing and packaging ingredients or foodstuffs to the consumer. In this regard, it has been noted that certain foodstuffs and/or ingredients are often best stowed or compartmentalized until the time of consumption or admixture.
Thus, the coaxial ingredient package assembly 10 may well function to package plural ingredients or foodstuffs in distinct coaxial compartments and preferably comprises at least one plastic, pliable, or pinchable inner foodstuff barrier or tube 11 as illustrated and referenced in Figure Nos. 1 - 4, 6, and 8 - 13, and 16; and a plastic, pliable, or pinchable outer foodstuff barrier or tube 12 as illustrated and referenced in Figure Nos. 1 - 5, and 7 - 16. Further, the package assembly 10 may be said to preferably comprise first and second package ends 13 as generally depicted and referenced in Figure Nos. 1, 3 - 5, and 9 - 15; and a longitudinal package axis 100 as depicted and referenced in Figure Nos. 1 - 4, 8, and 14.
The inner ingredient or foodstuff barrier 11 is preferably formed by way of a first vertical form fill and seal (VFFS) assembly 15 as generally depicted in Figure No. 16 and may preferably comprise a composite polymer material comprising state of the art materials such as polypropylene, polyester, paper, polyolefin extrusions, adhesive laminates, and other such materials. It is noted that for many ingredients, foodstuffs, or food products, flavor retention is highly important. In this regard, as is noted in the prior art, metalized food-contacting layers or surfaces provide excellent flavor retention when juxtaposed adjacent ingredients. Thus, it is contemplated that a metalized food or ingredient-contacting layer may preferably or alternatively form an innermost surface or layer 14 of foodstuff barrier 11 as generally referenced in Figure No. 6.
The film composition of inner foodstuff barrier 11 generally depicted in Figure No. 6 should in any event be ideally suited for use on vertical form and fill machines for the packaging of foodstuff ingredients or food products, as the methodology involved in constructing package assembly 10 preferably involves the use of tandem VFFS machines or assemblies as generally depicted in Figure No. 16. Both the innermost surface 14 of barrier 11 and the outermost surface or layer 16 of barrier 11 should provide excellent food-contacting barrier properties (as would, for example, a metalized thin layer of aluminum). Further, the outermost surface 16 of barrier 11 should enable sealing attachment to the innermost surface 14.
In this regard, it is noted that state of the art techniques for forming a longitudinal lap seal may involve the use of metalized oriented polypropylene (OPP) or metalized polyethylene terephtalate (PET). Excellent results may be achieved by utilizing OPP or PET for the outside or outermost surface 16 of barrier 11 insofar as the same enables state of the art heat sealing of the longitudinal back seal (or transverse seal) of the film. Notably, there is no requirement for an ink layer for the inner ingredient or foodstuff barrier 11 as viewable graphics and the like may be considered superfluous, the same being otherwise hidden or blocked from view by the outer barrier 12.
With reference to Figure Nos. 6 and 8, it will be seen that a portion of the inside surface layer 14 is mated with a portion of the outside surface or layer 16 in the area indicated by an arrow (in Figure No. 6) to form a lap seal 20 (referenced in Figure No. 8). The lap seal 20 in this area may typically be accomplished by applying heat and pressure to the film in such area. The lap seal design shown in the noted figures thus helps to insure that the product to be placed inside the formed package will be protected or isolated from matter radially external to the inner foodstuff barrier 11.
Inner foodstuff barrier 11 comprises a longitudinal lap seal 20 of the type generally described and depicted in Figure No. 8 so as to minimize packaging material volume extending into the interstices 17 between the inner foodstuff barrier 11 and the outer foodstuff barrier 12, which interstices 17 is generally referenced in Figure No. 8. From a comparative consideration of Figure Nos. 2 and 8, it will be understood that providing a lap seal 20 on barrier 11 will not only minimize packaging material volume, but maximize the outer foodstuff volume 18 and minimize obstruction(s) during axial displacement of the outer foodstuff or ingredient 28. The outer foodstuff volume 18 is generally referenced in Figure No. 2, and the outer foodstuff 28 is generally depicted and referenced in Figure Nos. 4, 9, 14, and 16.
The outer foodstuff barrier 12 is preferably formed by way of a second vertical form fill and seal (VFFS) assembly 19 tandemly juxtaposed in inferior adjacency to assembly 15 as further generally depicted in Figure No. 16. Outer foodstuff barrier 12 may also preferably comprise a composite polymer material comprising state of the art materials such as polypropylene, polyester, paper, polyolefin extrusions, adhesive laminates, and other such materials. As has been noted, many foodstuffs or food products benefit from the use of metalized food-contacting packaging layers or surfaces to retain food flavor. Thus, a metalized food-contacting layer may form an innermost layer or surface 23 of foodstuff barrier 12 as referenced in Figure No. 7.
The film composition of outer foodstuff barrier 12 generally depicted in Figure No. 7 should in any event be also be ideally suited for use on vertical form and fill machines for the packaging of food-based ingredients or food products, as the methodology involved in constructing package assembly 10 preferably involves the use of tandem VFFS machines or assemblies 15 and 19. The innermost surface 23 of barrier 12 should provide excellent barrier properties (as would, for example, a metalized thin layer of aluminum) and should enable sealing attachment unto itself. In this last regard, it is noted that state of the art techniques for forming a fin seal 22 may also involve the use of metalized oriented polypropylene (OPP) or metalized polyethylene terephtalate (PET). Excellent results may be achieved by utilizing OPP or PET for the inside or innermost surface 23 of barrier 12 insofar as the same enables state of the art heat sealing of the longitudinal back seal (or transverse seal) of the film. Notably, outer foodstuff barrier 12 may comprise an outer ink or graphics layer for the presentation of graphics that can be viewed through a transparent outside layer 24, which outside layer 24 may comprise state of the art OPP or PET materials.
In this last regard, it will be noted that a longitudinal fin seal 22 is used for longitudinally sealing the back of outer foodstuff barrier 12, which fin seal 22 is generally depicted in Figure Nos. 2, 8, and 9. Outer foodstuff barrier 12 comprises a longitudinal fin seal 22 of the type generally described and depicted so as to maximize the outermost (hermetic) seal integrity of the package assembly, it being generally understood that fin seals generally provide superior hermetic seals. Further, in contradistinction to the inner lap seal 20 which functions to provide a benefit by reducing interstitial packaging material volume, there is no equal benefit of this type external to the package and thus the outer fin seal 22 is to be preferred to provide a superior seal and barrier to matter external to the package assembly 10 such as air, bacteria, debris, etc.
The fin seal variation generally depicted also provides that the product to be placed in the formed package will be protected from the ink layer by the inside surface or layer 23. Again, the outside layer 24 does not normally contact any packaged foodstuff product. In the preferred embodiment depicted in Figure No. 7, the inside surface or layer 23 is folded over and then sealed on itself in the area indicated by the arrows. Again, this seal is accomplished by the application of heat and pressure to the film in the area illustrated as may be seen from a general inspection of Figure No. 16 at reference numeral 25.
It should perhaps be reiterated that the packaging materials that are fed into the form, fill and seal machines shown in Figure No. 16 are preferably packaging film(s), such as polypropylene, polyester, paper, polyolefin extrusions, adhesive laminates, and other such materials, or from layered combinations of the above. For many food products, where flavor retention is important, a metalized layer may form the innermost layer, and in the case of inner foodstuff barrier 11, a metalized layer may form both the innermost surface or layer 14 and the outermost surface or layer 16.
As may be further seen from an inspection of Figure No. 16, the inner foodstuff barrier 11 functions to receive an inner ingredient or inner foodstuff 26 and thereby forms an inner (food) package 27. The inner ingredient or inner foodstuff 26 is further illustrated and referenced in Figure Nos. 2, 4, 9, and 14. The outer foodstuff barrier 12, in turn, receives the inner food package 27 and an outer foodstuff 28 in substantially coaxial relation about the package axis 100. The inner foodstuff barrier 11 essentially functions to prevent contact intermediate the inner foodstuff 26 and the outer foodstuff 28 as further depicted in Figure Nos. 2, 4, 9, 14, and 16. The outer foodstuff barrier 12 essentially functions to prevent contact intermediate the outer foodstuff 28 and radially ambient matter or matter radially external to package assembly 10 (such as air or debris).
Finally, the first and second package ends 13 are preferably heat-pressure sealed to finally seal the package assembly 10. The sealed first and second package ends 13 effectively function to selectively prevent contact intermediate the inner and outer foodstuffs 26 and 28 and axially ambient matter or matter axially external to package assembly 10. In this last regard, the notion of selectively preventing contact intermediate the inner and outer foodstuffs 26 and 28 and axially ambient matter is meant to convey that the user may elect to enable contact therebetween, as for example, by opening the package assembly 10. It is thus contemplated that the coaxial foodstuff package or package assembly 10 may further preferably comprise certain manually-enabled, end-opening means for enabling a user to manually (in other words, with one's hand and/or fingers) open a select package end, the select package end being selected from the group consisting of the first and second package ends 13, but which may preferably be situated adjacent the top end as directed by implied by graphical indicia viewable via the outer package structures.
It is further contemplated that the end-opening means may be defined by certain select scoring as selected from the group comprising a singular score line 30 as generally depicted in Figure Nos. 11 and 13; paired score lines 31 as generally depicted in Figure Nos. 3, 10, 12, and 14; continuous score lines 32 as generally depicted in Figure Nos. 12 - 14, and skipped score lines 33 as generally depicted in Figure Nos. 3, 10, and 11. It will be seen from an inspection of the noted figures that the select scoring may be preferably transversely aligned or orthogonal to the package axis 100 for enabling a user to remove the select package end as comparatively depicted in Figure Nos. 10 and 14. It is further contemplated that the select scoring may be preferably laser scored as a means to enhance the user's ability to manually, evenly and simultaneously open the compartments 38 and 39 containing the inner foodstuff 26 and the outer foodstuff 28, respectively, to ambient matter, including, a user's mouth 101 as generally depicted in Figure No. 15.
In this last regard, it is contemplated that the preferred opening technology take the form of or be defined by a laser score. The laser score will be both on the inner tube 11 and the outer tube 12. It is further contemplated that the laser score may be preferably applied while the packages are in the web configuration, prior to being formed into a tube. As heretofore stated, the score can be of many different designs; a solid score, a skip score (as shown by dotted lines), a double score where the scores are preferably about 1 mm apart making it easier to align the inner and outer scores for a clean removal of the select package end (i.e. the top) of each tube. By using a laser score the entire select package end (i.e. the top) of the tube can be removed, making the dispensing of the ingredients or inner and outer foodstuffs 26 and 28 inside much cleaner or with minimal axial obstruction(s).
Certain foodstuff service and/or presentation methodology is inherently taught by the structure(s) heretofore disclosed and described. For example, a certain foodstuff service method is contemplated whereby contact between plural foodstuffs may be prevented prior to final foodstuff service. In this regard, the method is contemplated as comprising certain steps including, aligning an inner foodstuff such as inner foodstuff 26 about a foodstuff axis such as -package axis 100. The step of inner foodstuff alignment may be structurally achieved by bounding or packaging the inner foodstuff with a first foodstuff barrier such as inner foodstuff barrier 11 as generally depicted in Figure No. 1 at 35. The methodology may further comprise a step of coaxially aligning at least one outer foodstuff such as outer foodstuff 28 about the inner foodstuff (and the foodstuff axis). The step of outer foodstuff coaxial alignment may be structurally achieved by bounding or packaging the outer foodstuff(s) with a second or secondary foodstuff barrier(s) such as outer foodstuff 12 as generally depicted in Figure No. 15 at 36.
After the respective foodstuffs are axially aligned, the same may be sealed from ambient matter (such as air or debris) for stowing and/or transporting the ingredients or foodstuffs and the foodstuffs may be unsealed or opened to ambient matter (such as a plate or one's mouth) prior to final foodstuff service. After opening or unsealing the otherwise sealed foodstuffs, it is contemplated that the methodology may involve the step of finally serving the inner and outer foodstuffs to the foodstuff consumer, as for example, by setting the coaxially aligned foodstuffs in front of the foodstuff consumer or by dispensing the foodstuffs from coaxial alignment directly to the foodstuff consumer, as for example, by dispensing the contents directly into one's mouth as generally depicted in Figure No. 15.
Notably, the step(s) of foodstuff alignment and foodstuff sealing may be defined by the process of packaging the foodstuff in respective foodstuff sheathing such as inner and outer foodstuff barriers 11 and 12. Thus, the methodology here contemplated may further involve the step of preventing foodstuff contact during the step of coaxial foodstuff alignment. Further, the inner and outer foodstuffs may be simultaneously and axially displaced during final foodstuff service as for example, by squeezing, pinching (as at 37 in Figure Nos. 9 and 14) or otherwise forcing the foodstuffs from the structures herein specified, which structures may be defined as an inner chamber 38 and an outer chamber 39 both of which are generally referenced in Figure No. 8.
In this last regard, it is contemplated that the user may elect to allow gravitational force to pull foodstuffs or other ingredient contents from the inner and outer chambers 38 and 39 as generically depicted in Figure No. 14 where both gravitational force (in other words, the weight of package contents as depicted at vector arrow 40) and the user's pinching action 37 may operate to force foodstuffs 26 and 28 from chambers 38 and 39 for further processing. Thus, it may be said that inner and outer foodstuffs may be manually forced into axial displacement by pinching the foodstuffs along the foodstuff axis.
Typically, after having been finally served the foodstuffs, the user may elect to mix the foodstuffs out of coaxial or concentric alignment. This may be achieved in any number of ways, not the least of which is via mouth-mixing the foodstuffs as implicitly shown in Figure No. 15. Notably, should the user elect to dispense container contents directly into one's mouth from the open select package end, admixture of ingredients may be effectively achieved thereby to effect flavor and enjoyment prior to admixed foodstuff or ingredient consumption.
It is contemplated that the process of presenting foodstuff(s) may differ somewhat from foodstuff service methodology heretofore set forth. The presentation method or method for coaxially presenting plural foodstuffs to a foodstuff consumer is believed to essentially comprise the steps of coaxially aligning a plurality of foodstuffs about a foodstuff axis. The process of coaxial foodstuff alignment is believed to set up the process of axial displacement of foodstuffs along the foodstuff axis, which process, in turn, sets up the process of coaxial presentation of foodstuffs to a foodstuff consumer. In other words, after axially displacing the coaxially aligned foodstuffs, the same may be presented to the foodstuff consumer. As before, the plural foodstuffs may be prevented from contacting one another during coaxial foodstuff alignment. Further, should the foodstuffs benefit from being sealed from ambient matter (as for example for stowage on a market shelf), it is further contemplated that the foodstuffs may be sealed from ambient matter and opened prior to axial foodstuff displacement, the displacement may be effectively achieved or effected by way of pinching action or other forceful means as heretofore contemplated.
While the above description contains much specificity, this specificity should not be construed as limitations on the scope of the invention, but rather as an exemplification of the invention. For example, the invention may be described as a coaxial foodstuff package having distinct coaxial compartments for housing distinct ingredients, the separation of which may be beneficial until to the actual time of consumption. The disclosed preferred embodiments have illustrated a two chamber foodstuff package. However, a coaxial foodstuff package comprising more than two distinct compartments according to the teachings set forth herein is contemplated. Should the manufacturer elect to form three or more coaxial compartments, it is contemplated that inner barriers should take the form of inner foodstuff barrier 11 and the outermost barrier should take the form of outer foodstuff barrier 12.
Further, a foodstuff or other ingredient package for packaging and presenting plural foodstuffs or ingredients is disclosed. The package essentially comprises at least one inner foodstuff or ingredient barrier (such as barrier 11), an outer foodstuff or ingredient barrier (such as barrier 12), first and second package ends, and at least one longitudinal package axis (such as axis 100). The inner foodstuff barrier extends intermediate the outer foodstuff barrier and the package axis for receiving an inner foodstuff and forming an inner food package or packages. The outer foodstuff barrier receives the inner food package(s) and an outer foodstuff, which essentially fills the interstitial cavity intermediate the outer barrier and the inner food package(s). The inner foodstuff barrier essentially functions to prevent contact intermediate the inner and outer foodstuffs, and the outer foodstuff barrier essentially functions to prevent contact intermediate the outer foodstuff and radially ambient matter.
The first and second package ends are sealed for selectively preventing contact intermediate the inner and outer foodstuffs and axially ambient matter. In this regard, it is contemplated that a multiaxial foodstuff package may be gleaned from the teachings set forth herein wherein the foodstuff package may comprises plural inner foodstuffs bound by certain inner foodstuff barriers and a single outer foodstuff which fills the interstitial space intermediate the inner foodstuff barrier(s) and the outer foodstuff barrier. Further, in terms of a foodstuff presentation method, the method for presenting plural foodstuffs to a foodstuff consumer may be said to comprise the steps of axially displacing axially aligned plural foodstuffs along the foodstuff axes for axially presenting plural foodstuffs to a foodstuff consumer; and presenting the axially aligned and axially displaced foodstuffs to the foodstuff consumer. This method may be preferably defined by coaxially aligning the plural foodstuffs or ingredients prior to axial displacement.
As a last point, it will be seen that the types of ingredients storable in the package do not necessarily have to be overtly reactionary with one another as would be the case with gasified candy and moisture-laden ingredients such as pudding. The package may well function to separate ingredient pairs and the like such as cottage cheese on the outside and a fruit sauce on the inside (similar to the ingredients of BREAKSTONE'S® / KNUDSEN® COTTAGE DOUBLES® brand(s) snack packs); chocolate sauce on the outside and marshmallow cream on the inside; pudding on the outside and whipped cream on the inside; peanut butter on the outside and jelly on the inside; ketchup on the outside and mustard on the inside; and pudding on the outside and gasified candy on the inside. The package can be manufactured so that the contents including both foodstuffs can be visible through the transparency of the film used for the package or the exterior product can be partially seen through the transparency of the film so that the outer package can also carry the brand name and advertising of the manufacturer as needed.
Although described by reference to a preferred embodiment and certain alternative embodiments, it is not intended that the novel assembly be limited thereby, but that modifications thereof are intended to be included as falling within the broad scope of the foregoing disclosure, the following claims and the appended drawings.
