     BACKGROUND OF INVENTION  
      1. Field of Invention  
      The invention relates generally to wraps for beverage containers, and more specifically to wraps that absorb and/or contain condensation that develops on the outside of beverage containers.  
      2. Discussion of Related Art  
      A beverage container carrying a cold beverage can form condensation on the outside of the container. This condensation may be uncomfortable to some as they hold the container. When the container is set down on a surface, condensation can damage the surface or water puddles can damage articles present on the surface.  
      Many beverage container wraps are known which are designed to absorb condensation that forms on beverage containers. For example, U.S. Pat. No. 5,102,036 to Orr, et al. is directed to a container wrap that includes an outer layer of bendable kraft board, and further includes corrugated paper on its inner surface that wraps around the sides of a beverage container and absorbs condensation.  
      While various beverage container wraps are available, a need exists for beverage container wraps which provide improved absorption and/or containment of excess condensation.  
     SUMMARY OF INVENTION  
      In one embodiment, a wrap for a beverage container includes a sleeve portion having a top end and a bottom end, and a base portion disposed at the bottom end of the sleeve. The base portion includes an absorbent material selected from the group consisting of: single-faced microflute cardboard; cotton; a starch-based material; and a water-soluble polymer.  
      In another embodiment of the invention, a wrap for a beverage container includes a first portion forming a frusto-conical sleeve for wrapping at least a portion of the side of the beverage container, the first portion comprising a first absorbent material. The wrap also includes a second portion forming a base disposed at or near a bottom of the sleeve, the second portion comprising a second absorbent material.  
      According to yet another embodiment of the invention, a wrap for a beverage container includes a first portion forming a frusto-conical sleeve for wrapping at least a portion of the side of the beverage container, and a second portion forming a base disposed at or near a bottom of the sleeve. The sleeve is integral with the base, and at least one of the sleeve and the base comprises an absorbent material.  
      According to another embodiment of the invention, a blank for forming a wrap for a beverage container includes an arcuate strip having a lower end, with a first curved edge, for forming at least a portion of a bottom end of a sleeve, and further having an upper end, with a second curved edge for forming at least a portion of a top end of the sleeve, such that when the blank is assembled into the wrap for the beverage container, the arcuate strip forms at least a portion of a frusto-conical sleeve. The blank further includes a first base portion extending from the lower end of the arcuate strip such that when the blank is assembled into the wrap for the beverage container, the first base portion is located at or near the bottom end of the sleeve. At least one of the base portion and the arcuate strip comprises an absorbent material that is exposed on a side that faces inwardly when the blank is assembled into the wrap for the beverage container.

     DETAILED DESCRIPTION  
      As described above, beverage containers carrying cold drinks can form condensation that may be uncomfortable and/or damaging. Embodiments of the invention described herein include a container wrap that helps deal with condensation by absorbing and/or containing excess condensation. In some embodiments of the invention, a wrap has a base provided with an absorbent material to catch condensation whether the container is held by a user or placed on a surface. The base may catch condensation that runs down the side of the container and/or the wrap, and/or the base may absorb or collect condensation formed on the bottom of the container.  
      In some embodiments of the invention, a wrap is shaped to conform to the shape of the container for ease of use and/or effective absorption. For example, cold drinks are sometimes served in cups which have a frusto-conical shape. A wrap may be constructed and arranged such that insertion of the frusto-conical cup into the wrap urges the wrap into a similar shape. In some embodiments, the wrap may be pre-shaped to match the shape of the container before the container is inserted.  
      In some embodiments, a wrap with a frusto-conical sleeve may have a one-piece construction so that it is easily manufactured and assembled. The wrap may include a sleeve portion integral with a base portion, with at least one of the two portions including an absorbent material. In some embodiments, the sleeve portion and/or the base portion may comprise multiple portions that are attached together.  
      In some embodiments of the invention, a blank is provided, for example a die-cut blank, that is easily assembled into a wrap and optionally foldable. The blank may include an arcuate strip having a base portion that extends from a bottom end of the strip. The blank may be constructed and arranged such that when the blank is assembled into a wrap for a container, the arcuate strip forms at least a portion of a frusto-conical sleeve. The base portion and/or the arcuate strip may include an absorbent material that faces inwardly when the blank is assembled to accommodate excess condensation.  
      In some embodiments, the beverage container wrap is (1) easy to manufacture, (2) easy to transport, (3) easy to use, and/or (4) easy to recycle. For example, in embodiments of the beverage container wrap which are used in fast food establishments or other high throughput establishments, it may be desirable to provide wraps which are quick and easy to convert from a flat, “storage” configuration to an opened, “use” configuration.  
      In some embodiments, a wrap for a beverage container may be constructed with two or more different materials—one material to provide structural support, and one material to provide absorptive properties. For example, a wrap may have an outer layer formed of a cardboard material, a paper material, a paperboard material, or other suitable material or combinations thereof. The wrap also may have an inner layer attached to the outer layer, the inner layer including a material that is not a cardboard material, a paper material, a paperboard material, or similar type of material.  
      It may be desirable to provide a wrap that tends to grip the container upon wetting. In some embodiments, a starch-based material may be used as an absorbent material in a container wrap. As the starch-based material absorbs condensation, it may become tacky and grip the container to reduce the possibility that the wrap dislodges from the container.  
       FIGS. 1   a  and  1   b  show a container  20  being inserted into a container wrap  22  according to one embodiment of the invention. A sleeve  24  of wrap  22  encircles a lower portion  26  of container  20  to absorb condensation that forms at least on lower portion  26 . Condensation that forms on an upper portion  28  of container  20  and falls to lower portion  26  also may be absorbed by wrap  22 . To absorb condensation that forms on a bottom of container  22  or condensation that sleeve  24  fails to absorb, wrap  22  optionally may include a base (not shown in  FIGS. 1   a  and  1   b ).  
      In one embodiment, wrap  22  completely encircles container  20 . However, the present invention is not limited in this respect as wrap  22  need not necessarily completely encircle container  20  as it may wrap less than the entire circumference of container  20 . Further, in the embodiment of  FIG. 1   b , wrap  22  is configured to wrap only lower portion  26  of container  20 ; however, the present invention is not limited in this respect as wrap  22  may cover all or part of upper portion  28  of container  20 .  
      To provide absorptive properties, sleeve  24  and the base of the wrap may include an absorbent material  40  on their inside surfaces. As shown in  FIG. 2 , a microflute cardboard material may be used to absorb condensation. In some embodiments, sleeve  24  and the base include the same absorbent material, while in other embodiments, the two portions include different absorbent materials, as the present invention is not limited in this respect.  
      To limit the bulk or cost of the sleeve of wrap  22 , in some embodiments the inside surface of sleeve  24  does not include an absorbent material, and, in fact, may include a water-repellant surface to hasten the movement of condensation down the side of the wrap toward the base. In such an embodiment, the base may be provided with a material that is able to absorb a greater amount of condensation.  
      To allow for high volume production, easy assembly, and/or easy transport, a wrap  22  may be formed using a blank, such as a die-cut blank. One embodiment of a blank  60  is illustrated in  FIG. 3 . Blank  60  comprises an arcuate strip  62  and an attached base portion  64 . Arcuate strip  62  has an upper edge  66  and a lower edge  68 . To assemble a wrap using blank  60 , a first side edge  70  is attached to a second side edge  72  to form a frusto-conical sleeve. Base portion  64  may be folded at an approximately right angle to arcuate strip  62  and a tab  74  may be attached to arcuate strip  62  to form a base of the wrap. Tab  74  may be attached to arcuate strip  62  with adhesive  75  or by any other suitable method. Assembly of a wrap from blank  60  may be automated or may be performed by a manual worker.  
      If blank  60  is not cut from an absorbent material, an absorbent material, such as those described below with reference to  FIGS. 5   a - 5   e , or others, may be attached to form blank  60 . In some embodiments, an absorbent material is attached to a large piece of support material before a blank is cut or otherwise produced. It should be noted that absorbent material need not be present at all locations on one side of the blank or on the inside of an assembled wrap, as the present invention is not limited in this respect.  
      Score lines (including curved score lines, creases, or perforations) may be provided at various locations to improve the folding characteristics of the assembled wrap and/or to improve the ease of assembly of a wrap from blank  60 . For example, in one embodiment, a first score line  67   a  may be provided approximately halfway along the length of arcuate strip  62 , a second score line  67   b  may be provided near side edge  72 , and a third score line  67   c  may be provided on base portion  64 . When a wrap is assembled from blank  60  (for instance, by attaching tab  74  to lower edge  66  and attaching first side edge  70  to second side edge  72 ) the wrap may be folded into a flat configuration, as shown in  FIG. 4 , along the fold lines. The flat configuration may be desirable for storage or transport. It should be noted that the present invention is not limited in this respect as additional or fewer or even no scores need be provided.  
      In the flat configuration shown in  FIG. 4 , wrap  22  may be easier to store and/or easier to transport than a wrap in an open configuration. Additionally, in the particular flat configuration of  FIG. 4 , a user may squeeze the folded sides of sleeve  24  (at score lines  67   a ,  67   b ) toward each other to open sleeve  24  and simultaneously open base  42  into a horizontal circle. Base  42  is shown in this particular flat configuration to be exterior to sleeve  24 . It should be noted that in some embodiments base  42  may be folded such that it is contained partially or wholly within sleeve  24 . The present invention is not limited to wraps that can be folded.  
      Many of the wrap embodiments disclosed herein may be provided with absorptive capacity through the use of one or more of many different types of absorbent materials.  FIGS. 5   a - 5   e  show cross-sectional views of several materials which may be used in base  42  according to various embodiments. The materials shown and described for base  42  may be alternatively or additionally be used in sleeve  24  or other portions of wrap  22 .  
       FIG. 5   a  shows a cross-sectional view of single-faced microflute cardboard which includes a cardboard face  82  and flute material  84  adhered to one another. Flute material  84  is configured to face inwardly toward the container base or container sides. The increased surface area of the flute material  84  as compared to flat cardboard may provide improved absorption properties.  
      For a more flexible and lighter wrap, flute material  84  without any cardboard face may be used as shown in  FIG. 5   b . In some embodiments, portions of wrap  22  may include flute material  84  alone while other portions may include single-faced microflute or double-faced microflute (not shown). In some embodiments, material such as corrugated cardboard, which can have larger flutes than microflute material, may be used.  
       FIG. 5   c  shows an absorbent material  86  attached to a support material  88 . For example, compressed cellulose (which is an example of absorbent material) may be attached to paperboard (which is an example of support material) to provide material for base  42  and/or sleeve  24 . Alternative absorbent materials may be used to provide support and/or absorption properties, such as kraft board, chip board, paper laminate, bogus kraft laminate, laminated bogus paper, or kraft board laminate. Further examples of absorbent substances that may be used include water soluble polymers, absorbent foam, woven or non-woven material, European pulp board, starch-based products, cotton, and sponge material. Various combinations of the above-listed materials may be used together within a single wrap.  
      In some embodiments, support material  88  may be a paper-based or cardboard-based material, and absorbent material  86  may be a non-paper-based and non-cardboard-based material that has absorptive properties, such a starch-based material or a cellulose material.  
      To provide increased surface area, a material  85 , as illustrated in  FIG. 5   d , having one side with a shape similar to that of single-faced microflute cardboard may be employed. Unlike single-faced microflute cardboard, however, no interior air gaps are present within the material. Instead, material  45  may be a one-piece construction formed with foam material, sponge material, starch-based material, paper-based material, or other suitable material. The additional absorptive material may provide additional absorption capacity for excess condensation.  
      In some embodiments, no outer support material is used, and the wrap may be formed with a single material, which may allow for easier manufacturing and/or better recyclability. For example, as shown in  FIG. 5   e , the base and/or sleeve may be formed with a pulp material  83 . Pulp material  83  may be a market pulp, meaning pulp that has been substantially dried into sheets. Examples of different pulps include: fluff pulp; northern bleached softwood kraft (NBSK) pulp; southern bleached softwood kraft (SBSK) pulp; northern bleached hardwood kraft (NBHK) pulp; southern bleached hardwood kraft (SBHK) pulp; and eucalyptus pulp, each of which can readily absorb water. Pulp is conventionally used as an input for paper or paperboard production, and typically is produced as a sheet material. Pulp may be a chemical pulp, a chemi-thermo mechanical pulp (CTMP), or in some cases a mechanical pulp or a thermo mechanical pulp (CTP). Pulp is available from various suppliers, including the International Paper Company, NorskeCanada, and Weyerhaeuser.  
      In one embodiment, pulp having a thickness of {fraction (1/32)}″ may be used, and in other embodiments, a thickness of {fraction (1/64)}″, {fraction (1/16)}″, ⅛″ or ¼″, or any other suitable thickness may be used. It should be noted that pulp may be used in combination with an outer support material such as paper or cardboard. In some embodiments, wraps that include pulp also may have a moisture-resistant or water-resistant outer layer or outer coating on part or all of the wrap.  
      As mentioned above, it may be desirable to provide a wrap that tends to grip the container upon wetting.  FIG. 6  shows wrap  22  including sleeve  24  formed substantially of a starch-based material, according to another embodiment of the invention. Certain starch-based materials may start dissolving upon wetting and provide a tacky or sticky surface that helps the wrap grip the container. Examples of starch-based materials include, corn starch, rice starch, wheat starch, and so on. Green Cell™ foam, available from KTM Industries, Inc. of Lansing, Mich., is one example of a starch-based material that may be used as an absorbent material. Another example of a starch-based material that may be used in some embodiments is a combination of starch and waste paper, for example the material used to make flupis® brand packaging peanuts, made by PSP Papierschaum A G, Achim, Germany.  
      Wrap  22  is shown in  FIG. 6  as not having a base, however, in some embodiments wrap  22  may include a base made of the same or different material as sleeve  24 .  
      A table is provided below of absorption rate testing results for several materials that may be used with wraps disclosed herein (Table 1). For each material, one milliliter of water was placed on the material. For materials which absorbed the water nearly instantaneously or within one second, “&lt;1 second” was recorded. For materials which did not absorb all of the water within two minutes, “&gt;120 seconds” was recorded.  
               TABLE 1                          Time to Absorb for Various Materials                     Absorbing Material   Time to Absorb                                 Dissolved Pulp (Reinforced Fiber)   &lt;1   second       Dissolved Pulp (Steeping Fiber)   &lt;1   second       Wet Polyvinyl Alcohol (PVA) Sponge   &lt;1   second       Cotton   &lt;1   second       Paper Towels (folded to form 16 layers)   &lt;1   second       ¼ inch Cellulose Pad (Spontex ®)   &lt;1   second       ¼ inch Cellulose Pad (Nylonge ®)   &lt;1   second       ⅛ inch Compressed Cellulose   2   seconds       Coated Crafiboard from Kramer Carton Co., top   45   seconds       layer removed and resulting top surface roughed               with sharp knife               Single-Faced E-Flute (microflute)   90   seconds,                          75% Absorption                         Coated Craftboard from Kramer Carton Co.   &gt;120   seconds,                         50% Absorption                         Molded Pulp   &gt;120   seconds       {fraction (1/20)} inch Double Layer Corn Starch Sheet   &gt;120   seconds       ¼ inch Corrugated Starch Sheet   &gt;120   seconds       ¼ inch Non-Corrugated Starch Sheet   &gt;120   seconds       3 Stacked Layers of 70 Pound Indented Bogus   &gt;120   seconds       Kraft Paper               6 Stacked Layers of 70 Pound Indented Bogus   &gt;120   seconds       Kraft Paper               Corrugated Double-Faced Cardboard   &gt;120   seconds       Thin Craftboard   &gt;120   seconds       Dry Polyvinyl Alcohol (PVA) Sponge   &gt;120   seconds                  
 
      For some of the embodiments of wraps disclosed herein, an outer layer that provides structural support may be desirable.  FIG. 7  shows a wrap  22  comprising a sleeve  24  that is formed with at least two different materials. A first, inner material  87  is formed with a material that is capable of absorbing condensation. A second, outer material  91  is formed with a material that is resistant to water or moisture. For example, outer material  91  may be a foam-based or plastic-based material that resists moisture, is hydrophobic or allows for the application of graphics to sleeve  24 . In some embodiments of the invention, the moisture barrier may be formed with a coating, such as polyurethane, or a thin film of water-resistant material that is provided on the exterior surface of the wrap.  
      Various wrap embodiments disclosed herein may be adapted to absorb condensation that moves down from an area of a container that is not wrapped. An upper edge  93  of sleeve  24  may have a surface area that absorbs condensation as it moves down the outside wall of the container. In some embodiments, upper edge  93  may be thicker than the remainder of sleeve  24  to provide additional absorption area. For example, in one embodiment of a wrap, upper edge  93  may have a thickness of {fraction ( 1 / 4 )}″, {fraction ( 3 / 8 )}″, or ½″. The remainder of sleeve  24  may have a thickness that is 25%, 50% or 75% of the upper edge thickness.  
      In some embodiments, instead of being a flat horizontal material, upper edge  93  may have features that provide additional surface area, such as ridges or vertical pieces of material that are arranged adjacent to one another.  
      Referring back to  FIG. 3 , the location of base portion  64  relative to a bottom portion  89  of arcuate strip  62  is illustrated according to one embodiment. Extensions  90 ,  92  are provided between base portion  64  and arcuate strip  62  and between base portion  64  and tab  74 . When assembled, this configuration may provide a wrap where the base is not directly adjacent to the sleeve. Unlike the embodiment illustrated in  FIG. 3 , extension  92  may be narrower than tab  74 .  
      In some embodiments, base portion  64  may be constructed and arranged such that the assembled wrap has a base that is close to lower edge  68 , or a base that is positioned above lower edge  68  of the sleeve (i.e., within the sleeve). For example, as illustrated in  FIG. 8 , no extensions are provided between arcuate strip  62  and base portion  64 , instead, base portion  64  is directly attached to arcuate strip  62 . Similarly, tab  74  is directly attached to base portion  64  without an extension.  
       FIG. 9  shows an alternative embodiment of a unitary blank  102  that can be assembled into a container wrap. Blank  102  includes two arcuate strips  104 ,  106  integrally attached to a base portion  64 . Side edges  110 ,  112  of arcuate strip  104  may be attached to opposed edges  114 ,  116  of arcuate strip  106  using adhesive, hook and loop fasteners or other suitable method. Arcuate strips  104 ,  106  each may have a fold portion  105 ,  107  located at one or both side edges. Fold portions  105 ,  107  may be folded around the exterior of the opposing arcuate strip to provide an area for attachment, for example with adhesive  75 . In alternative embodiments, fold areas  105 ,  107  may be folded within the interior of the opposing arcuate strip.  
      After attachment, the wrap may be folded along score lines  67   b ,  67   c , or elsewhere, into a flat configuration for transport and/or storage. Base portion  64  does not need to be integrally attached to arcuate strips  104 ,  106 . Base portion  64  may be attached with adhesive, a tab and slot arrangement, or by any other suitable method to either or both of the arcuate strips. The illustrated embodiment includes extensions  90 ,  92 , but as with each of the embodiments disclosed herein, the extensions may be omitted and base portion  64  may be attached directly to the arcuate strips.  
       FIG. 10  shows a unitary blank which may reduce material use during die-cutting operations. Blank  115  has two base portions  65   a ,  65   b  rather than one base portion, resulting in a blank that fits into a smaller bounding rectangle than some other embodiments. Such a design may allow for a higher number of blanks to be cut from a large piece of material as compared to some other embodiments.  
      In the embodiment of  FIG. 10 , the two base portions  65   a ,  65   b  are each integrally attached to arcuate strip  62  and arranged to be attached to one another along a diameter of the resulting base. Such an arrangement may have the additional advantage of a larger attachment area  77  than, for example, the attachment area between tab portion  74  and arcuate strip  62  of the embodiment illustrated in  FIG. 3 .  
       FIG. 11  shows an alternative embodiment of a blank  120  that can be assembled into a container wrap. A plurality of triangular segments  122  may be attached to arcuate strip  62  such that when folded inwardly, triangular segments  122  form a base for a wrap. Triangular segments  122  and/or arcuate strip  62  may include an absorbent material to absorb condensation.  
       FIG. 12  shows an alternative embodiment for attaching base portion  64  to arcuate strip  62  that may eliminate the use of an adhesive, or provide a stronger attachment when used in conjunction with an adhesive. An insertion tab  79  may be inserted into a slot  96  to attach base portion  64  to arcuate strip  62 . Somewhat similarly, arcuate strip  62  may have a tab  97  and a slot  98  for assembling the sleeve portion of the wrap. In alternative embodiments, slits (not shown) may be provided near side edges  70 ,  72  such that one slit extends to lower edge  68  and the opposed slit extends to upper edge  66  and they may be used to attach side edges  70 ,  72  together to form the sleeve portion.  
       FIG. 13  shows an alternative shape for a blank  130  configured to form a wrap for a cylindrical container such as an aluminum can. Upper edge  132  and lower edge  134  are straight so that a cylindrical tube is formed when a side edge  136  is attached to a side edge  138 .  
      In an alternative embodiment of the invention, a blank may include a central base portion having elongated trapezoids or triangles extending therefrom. The elongated trapezoids or triangles, attached to the center base portion along their shorter parallel side, may be folded upwardly to form a frusto-conical shape for receiving a container. A thin cardboard band or a ring may be used to bring the plurality of trapezoids toward a central access. In other embodiments, shapes other than triangles or trapezoids may be used.  
      In another embodiment of the invention, a method of manufacturing a beverage container wrap is provided. The method includes providing a blank having a sleeve portion and a base portion. The base portion may include an absorbent material. The sleeve portion may be shaped such that upon assembly, the sleeve has a frusto-conical shape. Side edges of the sleeve portion are attached to one another to form a sleeve, and the base portion, or an element extending from the base portion, is attached to the sleeve to form a base of the wrap.  
      Various manufacturing processes may be used during the manufacture of a wrap or a blank for assembly into a wrap. Blanks may be die-cut from sheets of material, portions of the wraps may be injection molded, thermoformed, or extruded. Foam expansion in a mold is another option, as is pulp molding.  
      It should be noted that embodiments of the wraps disclosed herein may be affixed or adhered to a cup or other container such that the container and wrap become one assembly. In other embodiments, a wrap may be formed on the exterior of the container during container production.  
      In some embodiments, a junction of the base and sleeve may be made to be relatively watertight in some embodiments. To produce such a wrap, the base may be attached to the sleeve around the entire perimeter of the base. For example, a wrap having the same general shape as the wrap shown in  FIG. 2  may be made of molded plastic, molded paper, or molded pulp and may include an absorbent material on the inside surface. In other embodiments, a wrap may be constructed solely with molded pulp or molded paper.  
      While in many of the embodiments described herein, a wrap having a base and a sleeve is shaped and configured such that the sleeve directly contacts an outer surface of a container, the sleeve may be sized such that it is larger than the outer surface of the container and does not contact the container unless the sleeve is squeezed by a user (for instance, while the user is holding the sleeve). In such an embodiment, the base may be configured to adhere or otherwise attach to the container. Alternatively, the wrap having an oversized sleeve may be designed for use as a coaster wherein the container is lifted out of and placed back into the wrap while the wrap remains on a surface.  
      For purposes herein, a “blank” is defined as a piece or pieces of material that are not finally assembled, but rather require at least one further operation. Multiple pieces, including different materials, may constitute a blank if the pieces are attached together into one article. A “unitary blank” is defined as a blank that is formed of a single piece of material.  
      For purposes herein, the term “attached” refers to separate pieces connected together by adhesive, a tab and slot arrangement, or any other attaching arrangement. The term “attached” also refers to pieces or portions that are integrally connected.  
      As used herein, the term “frusto-conical” shall be understood to not require absolute conformance to a mathematical definition of this term, but rather shall be understood to indicate a general shape as would be understood by one skilled in the art most closely related to the subject matter herein. As used herein, a frusto-conical sleeve means a sleeve that has a substantial portion which is frusto-conically shaped. For example, a frusto-conical sleeve is considered to include a sleeve which has both a frusto-conical portion and a cylindrical portion.  
      Any of the embodiments of wraps disclosed herein may include materials and/or surface features on the inner or outer surface of the wrap which provide an enhanced grip between the wrap and a container or between a user&#39;s hand and the wrap. Additionally, the exterior of the wrap may have a surface or a coating that allows for the printing of information and/or advertisements on the exterior of the wrap.  
      This invention is not limited in its application to the details of construction and the arrangement of components set forth in the description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having,” “containing,” “involving,” and variations thereof herein, is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.  
      Having thus described several aspects of at least one embodiment of this invention, it is to be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure, and are intended to be within the spirit and scope of the invention. Accordingly, the foregoing description and drawings are by way of example only.
