     BACKGROUND OF THE INVENTION 
     Presently (circa 2018) gable topped cartons (or flat topped cartons), such as gable topped milk (or juice) cartons, only have one internal chamber; and thus, if different contents (e.g., a milk and a chocolate milk) were to be stored within that one internal chamber, those different contents would mix, which depending upon the contents or goals, may be undesirable. 
     There is a need in the art for a single gable topped carton that has at least two internal chambers, wherein these two internal chambers are separate and independent from each other, wherein each such chamber may have its own access point, e.g., its own spout; such that different contents of the given internal chambers may be removably housed and/or dispensed from a single carton, but removably housed, without mixing, at least until dispensed. 
     And/or there is a need in the art for a single substantially flat topped carton that has at least two internal chambers, wherein these two internal chambers are separate and independent from each other, wherein each such chamber may have its own access point, e.g., its own spout; such that different contents of the given internal chambers may be removably housed and/or dispensed from a single carton, but removably housed, without mixing, at least until dispensed. 
     Additionally, marketers often desire to get new product samples (e.g., a new beverage flavor) tried and tested by a particular target market (e.g., consumers). However, getting such new product samples to be tried is often expensive and difficult to achieve. It would be desirable to provide a smaller sample container/chamber that is connected to a container with a larger chamber than the smaller sample chamber, wherein the overall exterior dimensions of this dual chambered carton are standardized and/or typical (e.g., standardized sizing present in the marketplace), such as a standard sized gable-topped carton or such as standard sized flat topped carton; which would allow the sample to be marketed conveniently with the dual chambered carton with overall exterior dimensions that are standardized. Thus, pre-existing shelving and storage for standard sized cartons could be readily used to store such dual chambered (smaller sample chamber and larger chamber). 
     It is to these ends that the present invention has been developed. 
     BRIEF SUMMARY OF THE INVENTION 
     To minimize the limitations in the prior art, and to minimize other limitations that will be apparent upon reading and understanding the present specification, embodiments of the present invention may describe a carton (gabled topped in some embodiments or substantially flat in other embodiments) with dual, separate, and independent, but adjoining chambers (for holding different contents). In some embodiments, each separate, independent, and adjoining chamber may have its own respective spout and removably coupled lid to provide removable closure and access to the given chamber. Such cartons may be used in methods for removably housing (and/or dispensing) a first liquid edible item in a first-chamber and for removably housing (and/or dispensing) a second liquid edible item in a second-chamber. (Note, use of “edible” herein may mean something that may be safely drinkable, e.g., a beverage.) In some embodiments, the first liquid edible item and/or the second liquid edible item may be selected from one or more of: different types of beverages; different types of milks (1%, 2%, skim, whole, non-fat, chocolate, strawberry, and the like); different types of juices; different types of liquid concentrates; and/or the like. 
     It is an objective of the present invention to provide a carton with dual chambers that are adjoined, but separate and independent from each other. 
     It is another objective of the present invention to provide a carton with dual chambers, wherein access to each respective chamber may be via its own spout, with its own removably coupled lid. 
     It is another objective of the present invention to provide a carton that has a gable top structure and look to the carton. 
     It is another objective of the present invention to provide a carton that has a substantially flat top structure and look to the carton. 
     It is another objective of the present invention to provide a dual chambered carton whose overall external dimensions and shape is that of a standard sized carton. 
     It is another objective of the present invention to provide a dual chambered carton wherein one chamber is larger and one chamber is smaller. 
     It is yet another objective of the present invention to provide a dual chambered carton wherein one chamber is larger and one chamber is smaller; and wherein the smaller chamber may be used for marketing and/or distributing samples (e.g., as in a new flavor to be tried). 
     These and other advantages and features of the present invention are described herein with specificity so as to make the present invention understandable to one of ordinary skill in the art, both with respect to how to practice the present invention and how to make the present invention.

     In some embodiments, an exterior cross-section of a width of a given carton may be substantially shaped as a regular polygon. See e.g.,  FIG. 3A ,  FIG. 3B , and/or  FIG. 3C . 
     In some embodiments, with respect to a vertical direction of a given carton, from a bottom of the carton to the oppositely disposed roof of the carton, the two chambers may be arranged adjacent to each other, with no gaps between the two chambers; and such that one of the two chambers does not substantially surround the other of the two chambers. 
       FIG. 2A  may depict a longitudinal cross-sectional view of carton  100 , showing two adjoining internal chambers, a first-chamber  201  and a second-chamber  202 .  FIG. 2B  may depict a longitudinal cross-sectional view of carton  100 , showing two adjoining internal chambers, first-chamber  201  and second-chamber  202 .  FIG. 2A  and  FIG. 2B  may differ from each other, in that the sizes (e.g., volumes) of the respective first-chamber  201  and second-chamber  202  shown may be of different sizes with respect to each other. 
     For example, and without limiting the scope of the present invention, in  FIG. 2A , a volume of first-chamber  201  may be substantially similar to a volume of second-chamber  202 . 
     For example, and without limiting the scope of the present invention, in  FIG. 2B , a volume of first-chamber  201  may be larger than a volume of second-chamber  202 . 
     Continuing discussing  FIG. 2A  and  FIG. 2B , in some embodiments, carton  100  may comprise two chambers, first-chamber  201  and second-chamber  202 . In some embodiments, first-chamber  201  and second-chamber  202  may share a common-interior-wall  203 . In some embodiments, common-interior-wall  203  may be a divider, a barrier, and/or a partition completely separating a volume of first-chamber  201  from a volume of second-chamber  202 . In some embodiments, common-interior-wall  203  may prevent contents of first-chamber  201  from mixing with contents of second-chamber  202 , while such contents may be removably housed in carton  100 . In some embodiments, a bottom of common-interior-wall  203  may attach to bottom-wall  104 . In some embodiments, a top of common-interior-wall  203  may attach to top-walls  103 . In some embodiments, sides of common-interior-wall  203  may attach to opposing vertical-walls  102 . In some embodiments, each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may be substantially enclosed by exterior-walls  101  and common-interior-wall  203 . In some embodiments, each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may be accessible by its own separate and independent spout  411  (see  FIG. 4  for spouts  411 ); such that carton  100  may be dual chambered and dual spouted. In some embodiments, common-interior-wall  203  may be substantially disposed within exterior-walls  101 . See e.g.,  FIG. 2A  and  FIG. 2B . 
     Continuing discussing  FIG. 2A  and  FIG. 2B , in some embodiments, first-chamber  201  may comprise a first-chamber-width  211 , which may be a width or a depth of first-chamber  201 . In some embodiments, second-chamber  202  may comprise a second-chamber-width  212 , which may be a width or a depth of second-chamber  202 . 
     In some embodiments, a length of carton  100  may be longer than first-chamber-width  211 . In some embodiments, a length of carton  100  may be longer than second-chamber-width  212 . In some embodiments, a length of carton  100  may be longer than first-chamber-width  211  plus that of second-chamber-width  212 . In some embodiments, in a vertical direction, carton  100  may be elongate; i.e., longer than wide; and longer than deep. 
     In  FIG. 2A , first-chamber-width  211  may be substantially similar, in terms of predetermined dimension, to second-chamber-width  212 . In  FIG. 2A , a ratio of first-chamber-width  211  to second-chamber-width  212  may be substantially one. 
     In  FIG. 2B , first-chamber-width  211  may be larger than second-chamber-width  212 . In  FIG. 2B , a ratio of first-chamber-width  211  to second-chamber-width  212  may be greater than one. In some embodiments, the ratio of first-chamber-width  211  to second-chamber-width  212  may be from 1.5 to 3.0. 
     In some embodiments, exterior-walls  101  and common-interior-wall  203  may be substantially flat and substantially planar. In some embodiments, exterior-walls  101  and common-interior-wall  203  may be substantially rigid to semi-rigid. In some embodiments, exterior-walls  101  and common-interior-wall  203  may not be significantly flexible, not elastic, and not significantly stretchable. In some embodiments, volumes of the first-chamber and the second-chamber may each be substantially predetermined, fixed, and not expandable. 
       FIG. 3A  may depict a transverse width (or depth) cross-sectional view of carton  100 , showing two adjoining internal chambers, first-chamber  201  and second-chamber  202 .  FIG. 3B  may depict a transverse width (or depth) cross-sectional view of carton  100 , showing two adjoining internal chambers, first-chamber  201  and second-chamber  202 .  FIG. 3A  and  FIG. 3B  may differ from each other, in that the sizes (e.g., volumes) of the respective first-chamber  201  and second-chamber  202  shown may be of different sizes with respect to each other.  FIG. 3A  may correspond with  FIG. 2A . And  FIG. 3B  may correspond with  FIG. 2B . 
       FIG. 3C  may depict a transverse width (or depth) cross-sectional view of carton  100 , showing two adjoining internal chambers, first-chamber  201  and second-chamber  202 .  FIG. 3C  may differ from  FIG. 3A  and from  FIG. 3B , in that in  FIG. 3C , instead of carton  100  comprising common-interior-wall  203 , in  FIG. 3C , carton  100  may comprise common-interior-wall  303 . In some embodiments, common-interior-wall  203  and common-interior-wall  303  may be substantially structurally and functionally equivalent to each other. In some embodiments, common-interior-wall  203  may be substantially flat and planar member; whereas common-interior-wall  303  may have bends; such as, but not limited to, two or more bends. In some embodiments, common-interior-wall  303  may be comprised of three substantially flat and planar portions, joined together with two disposed opposite bends (angles). See e.g.,  FIG. 3C . 
     In some embodiments, an overall exterior shape of a given carton may have predetermined dimensional boundaries that may be substantially similar to dimensional boundaries of existing gable topped milk cartons. In some embodiments, an overall exterior shape of a given carton may have predetermined dimensional boundaries that may be substantially similar to dimensional boundaries of existing gable topped juice cartons. 
       FIG. 4  may depict a left-side view of carton  100 , with lids  111  removed and showing two separate and independent spouts  411 . In some embodiments, each lid  111  may removably couple and seal a given spout  411 . See e.g.,  FIG. 1D  for lids  111 ; and see  FIG. 4  for spouts  411 . For example, and without limiting the scope of the present invention, a paired lid  111  and spout  411  may have complimentary threading for removable coupling to each other. 
     In some embodiments, each spout  411  may be located on a given portion of top-wall  103 . In some embodiments, each spout  411  may be located substantially symmetrically and/or substantially equidistance from a gable-top  105 . 
     In some embodiments, a spout (e.g., spout  411 ) for a given chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may be located on a top (e.g., top-wall  103 ), side (e.g., vertical-wall  102 ), or bottom (e.g., bottom-wall  104 ) of that given chamber. 
     In some embodiments, each spout  411  of the two chambers may point in a different, but not opposite, direction. Thus, in such embodiments it may not be desirable to open both spouts  411  and try to pour from both spouts  411  simultaneously, as undesirable spillage might occur; rather, it may be more desirable to pour from one given spout  411  at a time. In some embodiments, each spout  411  may be located at substantially a same height with respect to a common bottom of the given carton. In some embodiments, each spout  411  may be located on a different roof structure of the carton. In some embodiments, the spouts  411  of a given carton may be located on an upper portion or top portion of the given carton. See e.g.,  FIG. 4 . 
     In some embodiments, each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may removably hold (and/or store) a given liquid food item (e.g., a given beverage and/or a given liquid flavorant), that may be complimentary to each other and/or often used together close in time. 
     In some embodiments, each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may removably hold (and/or store) a given liquid, such as, but not limited to, a given beverage. 
     For example, and without limiting the scope of the present invention, first-chamber  201  may removably hold (and/or store) a milk of one type; while second-chamber  202  may removably hold (and/or store) a milk of another type. For example, and without limiting the scope of the present invention, different types of milks may be selected from milk of a given fat content (e.g., 1%, 2%, whole, skim, non-fat, fortified, or the like), and/or milk of a given flavor (e.g., chocolate, strawberry, or the like). 
     For example, and without limiting the scope of the present invention, first-chamber  201  may removably hold (and/or store) a juice of one type; while second-chamber  202  may removably hold (and/or store) a different juice. 
     For example, and without limiting the scope of the present invention, first-chamber  201  may removably hold (and/or store) a water of one type; while second-chamber  202  may removably hold (and/or store) a water of a different type (e.g., flavored and/or sparkling). 
     In some embodiments, each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may removably hold (and/or store) a given liquid, such as, but not limited to, a given liquid food item (e.g., beverages, different types of beverages, etc.), a liquid concentrate, and/or the like. 
     In some embodiments, a size (e.g., a volume) of each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may be predetermined according to consumer preferences or consumer purchasing behavior for a given target market. For example, and without limiting the scope of the present invention, a larger first-chamber  201  may removably house a non-flavored milk; while a smaller second-chamber  202  may removably house a flavored milk (e.g., chocolate or strawberry); wherein consumer purchasing behavior shows that more non-flavored milk is purchased compared to the flavored milk, by volume. 
     In some embodiments, a size (e.g., a volume) of each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may be predetermined according to a strength of flavor; wherein the more strongly flavored food item may be removably housed within a smaller chamber (e.g., second-chamber  202 ); and the less strongly flavored food item may be removably housed within a larger chamber (e.g., first-chamber  201 ). 
     In some embodiments, a size (e.g., a volume) of each chamber (e.g., first-chamber  201  and/or second-chamber  202 ) may total a volume typical of pre-existing milk carton volumes, such as, but not limited to, 8 ounces, a pint, a quart, a half-gallon, and/or the like. 
     In some embodiments, carton  100  may be used for a method for removably housing (and/or dispensing) a first liquid edible item in first-chamber  201  and for removably housing (and/or dispensing) a second liquid edible item in second-chamber  202 . (Note, use of “edible” herein may mean something that may be safely drinkable, e.g., a beverage.) 
     In some embodiments, carton  500  may appear substantially similar to carton  100  with respect to externally visible structures shared between carton  100  and carton  500 . For example, and without limiting the scope of the present invention, carton  500  may comprise exterior-walls  101 , vertical-walls  102 , top-walls  103 , bottom-wall  104 , spouts  411 , and lids  111  as these structures were discussed above with respect to carton  100 . In some embodiments, carton  500  may also further comprise gable-top  105  as this structure was discussed above with respect to carton  100 . See e.g.,  FIG. 5A ,  FIG. 5B , and  FIG. 5C . 
     However, carton  500  may differ from carton  100  in a shape and/or a size of two internal chambers of carton  500 . In some embodiments, in carton  500 , first-chamber  201  may be larger-chamber  501 . In some embodiments, in carton  500 , second-chamber  202  may be smaller-chamber  503 . In some embodiments, the designations of “larger” and “smaller” of larger-chamber  501  and smaller-chamber  503 , respectively, may be with respect to each other; that is, larger-chamber  501  may be larger by volume than smaller-chamber  503 . In some embodiments, carton  500  may comprise two separate but connected chambers of different sized volumes, that of larger-chamber  501  and smaller-chamber  503 . In some embodiments, larger-chamber  501  and smaller-chamber  503  are both integral to carton  500 . In some embodiments, larger-chamber  501  and smaller-chamber  503  may not be removed from carton  500 . In some embodiments, a combined volume of larger-chamber  501  plus smaller-chamber  503  may occupy an external (or total or overall) volume defined by the external structures of carton  500  (e.g., exterior-walls  101 , vertical-walls  102 , top-walls  103 , bottom-wall  104 , spouts  411 , and lids  111 ). In some embodiment, each of the two chambers of carton  500  (e.g., larger-chamber  501  and smaller-chamber  503 ) may have their own respective spout  411  and lid  111 , for providing access to the respective internal volume of the given chamber, as was the case for carton  100 . In some embodiments, larger-chamber  501  and/or smaller-chamber  503  may removably hold (store) liquids (such as, but not limited to, beverages and/or condiments). In some embodiments, when each respective lid  111  may be properly secured to its complimentary spout  411 , any contents (e.g., a first liquid) of one chamber (e.g., larger-chamber  501 ) may not mix nor come into physical contact with any contents (e.g., a second liquid) of the other chamber (e.g., smaller-chamber  503 ). See e.g.,  FIG. 5A ,  FIG. 5B , and  FIG. 5C . 
     In some embodiments, larger-chamber  501  may be a fixed and predetermined volume. In some embodiments, smaller-chamber  503  may also be a fixed and predetermined volume, but a different volume and a smaller volume as compared to larger-chamber  501 . In some embodiments, a ratio of the volume of larger-chamber  501  to the volume of smaller-chamber  503  may be from 8.00 to 1.04. In some embodiments, a ratio of the volume of larger-chamber  501  to the volume of smaller-chamber  503  may be from 10.00 to 1.04. In some embodiments, a ratio of the volume of larger-chamber  501  to the volume of smaller-chamber  503  may be from 20.00 to 1.04. 
     As shown in  FIG. 5A ,  FIG. 5B , and  FIG. 5C , a shape (three-dimensional shape) of smaller-chamber  503  may differ substantially and/or significantly from a shape (three-dimensional shape) of larger-chamber  501 . In some embodiments, the shape of smaller-chamber  503  may be fixed and predetermined. In some embodiments, the shape of larger-chamber  501  may also be fixed and predetermined, but of a different shape as compared to the shape of smaller-chamber  503 . As shown in  FIG. 5A ,  FIG. 5B , and  FIG. 5C , a bottom of larger-chamber  501  may be bottom-wall  104 . Whereas, as shown in  FIG. 5A ,  FIG. 5B , and  FIG. 5C , bottom-wall  104  may form no part of smaller-chamber  503 . In  FIG. 5A  and in  FIG. 5B , smaller-chamber  503  may have its own bottom separate and different from bottom-wall  104 . 
     In  FIG. 5A , smaller-chamber  503  may have smaller-chamber-bottom  507 . In some embodiments, smaller-chamber-bottom  507  may be a bottom wall of smaller-chamber  503 . In some embodiments, a plane of smaller-chamber-bottom  507  may be substantially parallel with a plane of bottom-wall  104 . 
     In  FIG. 5B , smaller-chamber  503  may have smaller-chamber-bottom  509 . In some embodiments, smaller-chamber-bottom  509  may be a bottom wall of smaller-chamber  503 . In some embodiments, a plane of smaller-chamber-bottom  509  may not be parallel with a plane of bottom-wall  104 . In some embodiments, a plane of smaller-chamber-bottom  509  may diverge from a plane of bottom-wall  104  at a fixed none zero angle that may be from 1 degree to 89 degrees, depending upon the given embodiment. 
     In both  FIG. 5A  and in  FIG. 5B , smaller-chamber  503  may comprise at least two internal wall structures, at least one internal side wall and at least one internal bottom. As noted above, such internal bottoms may be smaller-chamber-bottom  507  or smaller-chamber-bottom  509 , respectively. In some embodiments, the internal side wall may be shared-internal-wall  505 . In some embodiments, shared-internal-wall  505  may be substantially vertical with respect to bottom-wall  104 . In some embodiments, shared-internal-wall  505  may be substantially perpendicular with respect to bottom-wall  104 . In some embodiments, shared-internal-wall  505  may run from a top of carton  500  (e.g., from top-wall  103  or from gable-top  105 ) towards bottom-wall  104 , but may not touch bottom-wall  104 . See e.g.,  FIG. 5A  and  FIG. 5B . Note, shared-internal-wall  505  may have some similarities with common-interior-wall  203  and common-interior-wall  303  of carton  100 ; except shared-internal-wall  505  may not touch bottom-wall  104 . 
     In some embodiments, smaller-chamber-bottom  507  may be a substantially planar member. In some embodiments, smaller-chamber-bottom  507  may be a substantially flat member. In some embodiments, smaller-chamber-bottom  507  may be a substantially concave. In some embodiments, smaller-chamber-bottom  507  may be a substantially convex. 
     In some embodiments, smaller-chamber-bottom  509  may be a substantially planar member. In some embodiments, smaller-chamber-bottom  509  may be a substantially flat member. In some embodiments, smaller-chamber-bottom  509  may be a substantially concave. In some embodiments, smaller-chamber-bottom  509  may be a substantially convex. 
     In some embodiments, shared-internal-wall  505  may be a substantially planar member. In some embodiments, shared-internal-wall  505  may be a substantially flat member. In some embodiments, shared-internal-wall  505  may be a substantially concave. In some embodiments, shared-internal-wall  505  may be a substantially convex. 
     In both  FIG. 5A  and in  FIG. 5B , shared-internal-wall  505  may also be a shared internal wall with larger-chamber  501 . In  FIG. 5A , smaller-chamber-bottom  507  may also be a shared internal wall with larger-chamber  501 . In  FIG. 5B , smaller-chamber-bottom  509  may also be a shared internal wall with larger-chamber  501 . See e.g.,  FIG. 5A  and  FIG. 5B . 
     In  FIG. 5A ,  FIG. 5B , and  FIG. 5C , smaller-chamber  503  may also be bound by portions of exterior-walls  101 , such as portions of vertical-walls  102  and/or portions of top-wall  103 . See e.g.,  FIG. 5A ,  FIG. 5B , and  FIG. 5C . 
     Discussing  FIG. 5C , in some embodiments, shared-internal-wall  505  may not be substantially perpendicular with respect to bottom-wall  104 . In some embodiments, shared-internal-wall  505  may run from a top of carton  500  (e.g., from top-wall  103  or from gable-top  105 ) towards bottom-wall  104  and towards a vertical-wall  102 , but may not touch bottom-wall  104 . In some embodiments, shared-internal-wall  505  may run from a top of carton  500  (e.g., from top-wall  103  or from gable-top  105 ) towards bottom-wall  104  and towards a vertical-wall  102 , and may physically contact that vertical-wall  102 . In some embodiments, shared-internal-wall  505  may run from a top of carton  500  (e.g., from top-wall  103  or from gable-top  105 ) towards bottom-wall  104  and towards a vertical-wall  102 , and may physically connect to and attach to that vertical-wall  102 . In some embodiments, smaller-chamber  503  may have one internal wall, that of shared-internal-wall  505 . See e.g.,  FIG. 5C . 
     Note in some embodiments, smaller-chamber  503  may be a “sample chamber” or “sample container”; wherein use of the word “sample” may refer to intended contents of smaller-chamber  503  being a sample, as in a product sample intended to be sold and marketed with the overall carton  500  to encourage consumers to try this sample. Because external dimensions of carton  500  may be that of standardized beverage cartons, providing a sample to consumers via carton  500  would not require any new infrastructure for shipping and/or storing cartons  500 . Thus, existing consumer, retailer, distributor, wholesaler, and manufacturer shelving and/or storage (including refrigerators and cold boxes) may readily accommodate cartons  500 , with the integral sample container (smaller-chamber  503 ). 
     In some embodiments, carton  500  may be used in a method for marketing and/or distributing a sample liquid edible product by housing the sample edible product within smaller-chamber  503 ; wherein the smaller-chamber  503  may be in physical contact with larger-chamber  501 , wherein the larger-chamber  501  may contain an established liquid edible product; wherein single carton  500  may be formed from both smaller-chamber  503  and larger-chamber  501 ; wherein larger-chamber  501  may be larger than smaller-chamber  503  by volume; wherein exterior dimensions of carton  500  may be substantially the same as exterior dimensions of a (standardized) container that holds just the established liquid edible product. 
     In some embodiments, sample liquid edible product may be selected from: different types of beverages; different types of milks (1%, 2%, skim, whole, non-fat, chocolate, strawberry, and the like); different types of juices; different types of liquid food items; different types of liquid concentrates (e.g., which may be added to an existing drink); different types of liquid flavorants; and/or the like. 
     Advantages to a consumer (or end-user) of such a smaller-chamber  503  being a sample chamber in carton  500 , may include: 
     (a) Ease of opening and ease of use of carton  500 , smaller-chamber  503  and larger-chamber  501 ; 
     (b) Overall carton  500  does not take any extra or additional storage space as compared to a normal or typical carton without such a smaller-chamber  503 ; 
     (c) Provides an opportunity for the consumer to enjoy an extra new product (the sample) that may be housed within smaller-chamber  503 ; and 
     (d) may provide an opportunity for the consumer to try the extra new product (the sample) without the consumer having to pay for the extra new product. 
     Advantages to providers, distributors, sellers, of cartons  500  with the smaller-chamber  503  that may be used as a sample chamber may include: 
     (a) Providing a convenient and cost-effective way to get the sample in front of consumers (e.g., directly into their homes and/or businesses) where the consumer may decide when to try the sample provided in smaller-chamber  503  at their own leisure; 
     (b) No need to use or rely upon in-store taste testing to promote new products, because now the given sample may be included in each sale of a given carton  500 , with the sample housed in smaller-chamber  503 ; 
     (c) Eliminates need to manufacture, store, and distribute standalone sample containers that have historically been used to test new products; 
     (d) Eliminates need for standalone marketing campaigns dedicated to promoting a new product, because now the new product can just be sold to existing customers an already established product (the already existing product is housed in larger-chamber  501  and the new product, the sample, is housed within smaller-chamber  503 ); 
     (e) Carton  500  with the two different sized chambers is efficient and cost effective for mass production; and/or 
     (f) A weaker selling product may be housed in smaller-chamber  503  and sold with a popular product housed in larger-chamber  501 , thus providing an opportunity to create more interested in the weaker selling product. 
       FIG. 6  may show a perspective view of a carton  600  with both larger-chamber  501  and smaller-chamber  503 ; and  FIG. 6  may also show smaller-chamber  503  without the remainder of carton  600 .  FIG. 6  may serve at least two purposes: (1) to show possible structure and geometry of smaller-chamber  503  without showing carton  500  or carton  600 ; and/or (2) that in some embodiments, smaller-chamber  503  may have a different top shape as compared against top-walls  103  of carton  600 . 
     Discussing  FIG. 6 , in some embodiments, carton  600  may appear substantially similar to carton  500  with respect to externally visible structures shared between carton  500  and carton  600 . For example, and without limiting the scope of the present invention, carton  600  may comprise exterior-walls  101 , vertical-walls  102 , top-walls  103 , bottom-wall  104 , spouts  411 , and lids  111  as these structures were discussed above with respect to carton  100 . In some embodiments, carton  600  may also further comprise gable-top  105  as this structure was discussed above with respect to carton  100 . Further, like carton  500 , carton  600  may comprise larger-chamber  501  and smaller-chamber  503 . Note in  FIG. 6 , shared-internal-wall  505  is referring to the back vertical wall of smaller-chamber  503 . See e.g.,  FIG. 6 . 
     How carton  600  shown in  FIG. 6  may differ from carton  500  is that in some embodiments of carton  600 , smaller-chamber  503  may have a different top shape as compared against top-walls  103  of carton  600  (or as compared against top-walls  103  of carton  500 ). See e.g.,  FIG. 6 . 
       FIG. 7  may show a perspective view of a carton  700  with both a larger-chamber  701  and a smaller-chamber  703 . In some embodiments, carton  700  may appear substantially similar to carton  600  with respect to externally visible structures shared between carton  600  and carton  700 . For example, and without limiting the scope of the present invention, carton  700  may comprise exterior-walls  101 , vertical-walls  102 , top-walls  103 , bottom-wall  104 , spouts  411 , and lids  111  as these structures were discussed above with respect to carton  100 . In some embodiments, carton  700  may also further comprise gable-top  105  as this structure was discussed above with respect to carton  100 . Further, carton  700  may comprise larger-chamber  701  and smaller-chamber  703 . See e.g.,  FIG. 7 . 
     Discussing  FIG. 7 , in some embodiments, structurally and functionally, larger-chamber  701  may be substantially similar to larger-chamber  501 . In some embodiments, structurally and functionally, smaller-chamber  703  may be substantially similar to smaller-chamber  503 . In some embodiments, how carton  700  may differ from carton  600  (and from carton  500 ), is that smaller-chamber  703  may be removable from larger-volume  701 . In some embodiments, smaller-chamber  703  may be removably attached to larger-chamber  701 . In some embodiments, smaller-chamber  703  may be removably attached to larger-chamber  701  via fastener(s)  711 . In some embodiments, fastener(s)  711  may be a type of mechanical fastener. In some embodiments, fastener(s)  711  may be a Velcro type of fastener, i.e., a plurality of hooks on one surface and a plurality of loops on a complimentary surface intended to be mated with the one surface with the plurality of hooks. In some embodiments, fastener(s)  711  may be tongue and grove type of mechanical sliding fastener, i.e., a tongue on one surface and a groove on a complimentary surface intended to be mated with the one surface with the tongue. These surfaces may be internal-wall  705  and mating-internal-wall  706 , respectively. In some embodiments, fastener(s)  711  may be a frictional press fit. Such fasteners  711  are well understood by those of ordinary skill in the relevant art and such fastener disclosures are incorporated herein. 
     Continuing discussing  FIG. 7 , in some embodiments, smaller-chamber  703  may bound a substantially fixed and predetermined volume defined by side walls and a bottom. In some embodiments, these side walls may be three vertical-walls  702  and one internal-wall  705  (that may also be a vertical wall and opposing one of the vertical-walls  702 ). And the bottom wall may be smaller-chamber-bottom  707 . Note in  FIG. 7 , internal-wall  705  is referring to the back vertical wall of smaller-chamber  703 . Further note, internal-wall  705  is referred to an internal wall because when smaller-chamber  703  may be removably attached to larger-volume  701 , internal-wall  705  is an internal wall in that attached configuration, with respect to overall carton  700 . See e.g.,  FIG. 7 . 
     Continuing discussing  FIG. 7 , in some embodiments, larger-chamber  701  may bound a substantially fixed and predetermined volume defined by side walls and a bottom. In some embodiments, these side walls may be four vertical-walls  702  and one mating-internal-wall  706  (that may also be a vertical wall and opposing one of the vertical-walls  702 ). And the bottom wall may be bottom-wall  104 . In some embodiments, the volume of larger-chamber  701  may also be bound by a top wall located below mating-internal-wall  706 , that of supportive-floor  708 . Note, mating-internal-wall  706  is referred to an internal wall because when smaller-chamber  703  may be removably attached to larger-volume  701 , mating-internal-wall  706  is an internal wall in that attached configuration, with respect to overall carton  700 . Note, mating-internal-wall  706  is referred to a mating wall because when smaller-chamber  703  may be removably attached to larger-volume  701 , mating-internal-wall  706  is mated to and/or proximate to internal-wall  705  of smaller-chamber  703 . Note, supportive-floor  708  is referred to a supportive floor because when smaller-chamber  703  may be removably attached to larger-volume  701 , supportive-floor  708  supports smaller-chamber-bottom  707  of smaller-chamber  703 . See e.g.,  FIG. 7 . 
     Continuing discussing  FIG. 7 , in some embodiments, structure shared-internal-wall  505  may be replaced with internal-wall  705  and mating-internal-wall  706 . In some embodiments, internal-wall  705  and mating-internal-wall  706  may be substantially parallel surfaces when smaller-chamber  703  may be removably attached to larger-chamber  701 . In some embodiments, internal-wall  705  and mating-internal-wall  706  may be mating surfaces when smaller-chamber  703  may be removably attached to larger-chamber  701 . In some embodiments, internal-wall  705  and mating-internal-wall  706  may be in physical contact with each other when smaller-chamber  703  may be removably attached to larger-chamber  701 . Similarly, in some embodiments, structure smaller-chamber-bottom  507  may be replaced with smaller-chamber-bottom  707  and supportive-floor  708 . In some embodiments, smaller-chamber-bottom  507  and supportive-floor  708  may be substantially parallel surfaces when smaller-chamber  703  may be removably attached to larger-chamber  701 . In some embodiments, smaller-chamber-bottom  507  and supportive-floor  708  may be mating surfaces when smaller-chamber  703  may be removably attached to larger-chamber  701 . In some embodiments, smaller-chamber-bottom  507  and supportive-floor  708  may be in physical contact with each other when smaller-chamber  703  may be removably attached to larger-chamber  701 . See e.g.,  FIG. 7 . 
     In some embodiments, fastener(s)  711  may be located on mating-internal-wall  706  and on internal-wall  705 , such that mating-internal-wall  706  may be removably attached to internal-wall  705 . See e.g.,  FIG. 7 . 
     In some embodiments, fastener(s)  711  may be located on supportive-floor  708  and on smaller-chamber-bottom  707 , such that supportive-floor  708  may be removably attached to smaller-chamber-bottom  707 . 
     In some embodiments, a ratio of the volume of larger-chamber  701  to the volume of smaller-chamber  703  may be as described for larger-chamber  501  and smaller-chamber  503 . 
     In some embodiments, smaller-chamber  703  may be a sample container or sample chamber, similar to smaller-chamber  503 . 
       FIG. 8  may show a perspective view of a carton  800  with both a larger-chamber  801  and a smaller-chamber  813 . In some embodiments, carton  800  may appear substantially similar to carton  100  with respect to externally visible structures shared between carton  100  and carton  800 . For example, and without limiting the scope of the present invention, carton  800  may comprise exterior-walls  101 , vertical-walls  102 , top-walls  103 , bottom-wall  104 , spouts  411 , and lid  111  as these structures were discussed above with respect to carton  100 . In some embodiments, carton  800  may also further comprise gable-top  105  as this structure was discussed above with respect to carton  100 . See e.g.,  FIG. 8 . 
     However, carton  800  may differ from carton  100  in a shape and/or a size of two internal chambers of carton  800 . In some embodiments, in carton  800 , first-chamber  201  may be larger-chamber  801 . In some embodiments, in carton  800 , second-chamber  202  may be smaller-chamber  813 . In some embodiments, the designations of “larger” and “smaller” of larger-chamber  801  and smaller-chamber  813 , respectively, may be with respect to each other; that is, larger-chamber  801  may be larger by volume than smaller-chamber  813 . In some embodiments, carton  800  may comprise two separate but connected chambers of different sized volumes, that of larger-chamber  801  and smaller-chamber  813 . In some embodiments, larger-chamber  801  and smaller-chamber  813  are both integral to carton  800 . In some embodiments, larger-chamber  801  and smaller-chamber  813  may not be removed from carton  800 . In some embodiments, a combined volume of larger-chamber  801  plus smaller-chamber  813  may occupy an external (or total or overall) volume defined by the external structures of carton  800  (e.g., exterior-walls  101 , vertical-walls  102 , top-walls  103 , bottom-wall  104 , spouts  411 , and lid  111 ). In some embodiment, each of the two chambers of carton  800  (e.g., larger-chamber  801  and smaller-chamber  813 ) may have their own respective spout  411 , lid  111  for larger-chamber  801 , and lid  811  for smaller-chamber  813 , for providing access to the respective internal volume of the given chamber, as was the case for carton  100 . In some embodiments, larger-chamber  801  and/or smaller-chamber  813  may removably hold (store) liquids (such as, but not limited to, beverages and/or condiments). In some embodiments, when each respective lid  111  and lid  811  may be properly secured to its complimentary spout  411 , any contents (e.g., a first liquid) of one chamber (e.g., larger-chamber  801 ) may not mix nor come into physical contact with any contents (e.g., a second liquid) of the other chamber (e.g., smaller-chamber  813 ). See e.g.,  FIG. 8 . 
     In some embodiments, larger-chamber  801  may be a fixed and predetermined volume. In some embodiments, smaller-chamber  813  may also be a fixed and predetermined volume, but a different volume and a smaller volume as compared to larger-chamber  801 . In some embodiments, a ratio of the volume of larger-chamber  801  to the volume of smaller-chamber  813  may be from 8.00 to 1.04. In some embodiments, a ratio of the volume of larger-chamber  801  to the volume of smaller-chamber  813  may be from 10.00 to 1.04. In some embodiments, a ratio of the volume of larger-chamber  801  to the volume of smaller-chamber  813  may be from 20.00 to 1.04. 
     As shown in  FIG. 8 , a shape (three-dimensional shape) of smaller-chamber  813  may differ substantially and/or significantly from a shape (three-dimensional shape) of larger-chamber  801 . In some embodiments, the shape of smaller-chamber  813  may be fixed and predetermined. In some embodiments, the shape of larger-chamber  801  may also be fixed and predetermined, but of a different shape as compared to the shape of smaller-chamber  813 . 
     In some embodiments, smaller-chamber  813  may be formed from vertical-walls  802 , top-wall  803 , and a bottom wall (not explicitly shown in  FIG. 8 , but nonetheless present in  FIG. 8 ). In some embodiments, smaller-chamber  813  may comprise its own lid  811 , that is removable from an underlying spout  411 , to provide access to the volume of smaller-chamber  813 . In some embodiments, top-wall  103  of carton  800  may comprise hole  810 . In some embodiments, hole  810  may be sized to accept passage of lid  811  of smaller-chamber  813 . In some embodiments, smaller-chamber  813  may fit fixedly within carton  800 , with lid  811  protruding from hole  810 . See e.g.,  FIG. 8 . 
       FIG. 9  may show a perspective view of a carton  900  with both a larger-chamber  921  and a smaller-chamber  923 . In some embodiments, carton  900  may appear substantially similar to carton  800  with respect to externally visible structures shared between carton  900  and carton  100 , except carton  900  may not be gabled. In some embodiments, a roof (e.g., top-wall  903 ) of carton  900  may be substantially flat and substantially parallel with a bottom of carton  900 . Aside from roof geometry differences between carton  900  and carton  800 , these two cartons may be substantially similar in other structures and in function and purpose. For example, and without limiting the scope of the present invention, carton  900  may comprise two different chambers, a larger-chamber  921  and a smaller-chamber  923 , wherein contents of these two chambers do not mix and are maintained separate within carton  900 . In some embodiments, larger-chamber  921  may be larger than smaller-chamber  923 . 
     In some embodiments, carton  900  may comprise exterior-walls  901 , vertical-walls  902 , top-walls  903 , bottom-wall (present in  FIG. 9  but not shown explicitly), spouts  411 , lid  111 , and lid  911 . In some embodiments, exterior-walls  901  may comprise vertical-walls  902 , top-walls  903 , bottom-wall (present in  FIG. 9  but not shown explicitly). In some embodiments, an exterior of carton  900  may be substantially formed by vertical-walls  902 , top-walls  903 , and bottom-wall (present in  FIG. 9  but not shown explicitly). See e.g.,  FIG. 9 . 
     In some embodiments, in carton  900 , first-chamber  201  may be larger-chamber  921 . In some embodiments, in carton  900 , second-chamber  202  may be smaller-chamber  923 . In some embodiments, the designations of “larger” and “smaller” of larger-chamber  921  and smaller-chamber  923 , respectively, may be with respect to each other; that is, larger-chamber  921  may be larger by volume than smaller-chamber  923 . In some embodiments, carton  900  may comprise two separate but connected chambers of different sized volumes, that of larger-chamber  921  and smaller-chamber  923 . In some embodiments, larger-chamber  921  and smaller-chamber  923  are both integral to carton  900 . In some embodiments, larger-chamber  921  and smaller-chamber  923  may not be removed from carton  900 . In some embodiments, a combined volume of larger-chamber  921  plus smaller-chamber  923  may occupy an external (or total or overall) volume defined by the external structures of carton  900  (e.g., exterior-walls  901 , vertical-walls  902 , top-walls  903 , the bottom-wall, spouts  411 , lid  111 , and lid  911 ). In some embodiment, each of the two chambers of carton  900  (e.g., larger-chamber  921  and smaller-chamber  923 ) may have their own respective spout  411 , lid  111  for larger-chamber  921 , and lid  911  for smaller-chamber  923 , for providing access to the respective internal volume of the given chamber, as was the case for carton  100 . In some embodiments, larger-chamber  921  and/or smaller-chamber  923  may removably hold (store) liquids (such as, but not limited to, beverages and/or condiments). In some embodiments, when each respective lid  111  and lid  911  may be properly secured to its complimentary spout  411 , any contents (e.g., a first liquid) of one chamber (e.g., larger-chamber  921 ) may not mix nor come into physical contact with any contents (e.g., a second liquid) of the other chamber (e.g., smaller-chamber  923 ). See e.g.,  FIG. 9 . 
     In some embodiments, larger-chamber  921  may be a fixed and predetermined volume. In some embodiments, smaller-chamber  923  may also be a fixed and predetermined volume, but a different volume and a smaller volume as compared to larger-chamber  921 . In some embodiments, a ratio of the volume of larger-chamber  921  to the volume of smaller-chamber  923  may be from 8.00 to 1.04. In some embodiments, a ratio of the volume of larger-chamber  921  to the volume of smaller-chamber  923  may be from 10.00 to 1.04. In some embodiments, a ratio of the volume of larger-chamber  921  to the volume of smaller-chamber  923  may be from 20.00 to 1.04. 
     As shown in  FIG. 9 , a shape (three-dimensional shape) of smaller-chamber  923  may differ substantially and/or significantly from a shape (three-dimensional shape) of larger-chamber  921 . In some embodiments, the shape of smaller-chamber  923  may be fixed and predetermined. In some embodiments, the shape of larger-chamber  921  may also be fixed and predetermined, but of a different shape as compared to the shape of smaller-chamber  923 . 
     In some embodiments, smaller-chamber  923  may be formed from vertical-walls  904 , top-wall  905 , and a bottom wall (not explicitly shown in  FIG. 9 , but nonetheless present in  FIG. 9 ). In some embodiments, smaller-chamber  923  may comprise its own lid  911 , that is removable from an underlying spout  411 , to provide access to the volume of smaller-chamber  923 . In some embodiments, top-wall  903  of carton  900  may comprise hole  910 . In some embodiments, hole  910  may be sized to accept passage of lid  911  of smaller-chamber  923 . In some embodiments, smaller-chamber  923  may fit fixedly within carton  900 , with lid  911  protruding from hole  910 . See e.g.,  FIG. 9 . 
     Also note, in  FIG. 9 , chambers-vertical-boundary  909  may demark a vertical boundary between larger-chamber  921  and smaller-chamber  923 . 
     Note, in some embodiments, the smaller-chambers shown in  FIG. 8  (and in  FIG. 9 ) may not be a mere continuation of the removable smaller-chamber shown in  FIG. 7 . Rather the depictions of the smaller-chambers (e.g.,  813 ,  923 , respectively) shown in  FIG. 8  and in  FIG. 9  may support the following different embodiments: (1) wherein the given smaller-chamber may be built into its respective larger-chamber as one integral carton, wherein disconnect between the given smaller-chamber and its respective larger-chamber is not intended; (2) wherein the given smaller-chamber may be removable from its respective larger-chamber; or (3) wherein the given smaller-chamber may exist as an insert into its respective larger-chamber. 
     In some embodiments, a portion of the second-chamber (larger-chamber) may be located beneath the first-chamber (smaller-chamber) with respect to a vertical direction from a bottom of the carton towards a roof of the carton. See e.g.,  FIG. 5A  through  FIG. 9 .
