Title: Universal elastic implement for smoking tobacco, cannabis and e-cigarettes with a built-in screen

Description:
CROSS-REFERENCE DATA 
     This patent application claims a priority benefit from a co-pending U.S. patent application Ser. No. 29/682,850 entitled “Universal elastic implement for smoking tobacco, cannabis, and e-cigarettes with a built-in filter” by the same inventor and filed on Mar. 8, 2019, which is incorporated herein by reference in its entirety. 
     BACKGROUND 
     Without limiting the scope of the invention, its background is described in connection with smoking devices and accessories. More particularly, the invention describes a universal implement configured to removably retain a cigarette, an e-cigarette, a cigar, a smoking pipe or alike on one end and an optional smoke filter on the other. 
     Smoking is a practice in which a combustible material, typically a plant such as tobacco, cannabis, or even herbs, is slowly burned and the resulting smoke is inhaled by the smoker. Combustion of the substance causes the release into the smoke of active drugs such as nicotine or THC, and therefore makes them available for a smoker to absorb through the lungs upon inhalation. The most common way of smoking today is via cigarettes, primarily industrially manufactured but also hand-rolled using rolling paper for example. Other smoking tools include traditional pipes, cigars, hookahs and water-pipes, or bongs. A more recent addition to a variety of smoking devices is a so-called e-cigarette, which does not produce a smoke in a technical sense of the word but instead causes evaporation of an inhalable aerosol, which may contain suspended particles desired to be consumed by the smoker. 
     For the purposes of this description, a variety of cigarettes, cigars, smoking pipes, cannabis joints, bongs, water pipes and other smoking devices are referred to collectively as a tubular container with burning smoking material. Included in this definition are all smoking devices in which the actual smoking material may be positioned somewhat away from the tubular container but is still connected thereto, for example as is the case with water pipes. Also included in this definition are e-cigarettes and their aerosolized analogs. 
     People smoke for recreation, as a part of rituals, and for medical purposes. It will be appreciated that, while cannabis for recreational use is illegal in many parts of the world, its use as a medicine is legal in a number of countries, including Canada, Austria, Germany, the Netherlands, Spain, Israel, Italy, Finland, and Portugal. In the United States, permission for medical use of cannabis varies from state to state, several having enacted laws to allow regulated cannabis consumption, possession, cultivation, and distribution for medicinal purposes. Therefore, legal statutes now permit both the recreational and medical use of cannabis for the delivery of THC (Δ9-tetrahydrocannabinol), CBD (cannabidiol), and other cannabinoids to a user in many parts of the world. 
     Inhaling combusted cannabis is the most common, effective, and least expensive method for delivering a pharmacological action of THC to the brain and body. The THC dose of inhaled cannabis smoke is largely determined by the concentration of precursor THCA (tetrahydrocannabinolic acid) present in the buds and small leaves of the plant and its temperature-dependent conversion to THC during combustion. 
     Though smoking is commonplace and enjoyable, inhalation of smoke resulting from burning of any plant substance may adversely affect the health of a smoker. Carcinogens in tobacco or cannabis smoke may increase a smoker&#39;s risk of developing cardiovascular disease, pulmonary disease, cancer, and other diseases. Many industrially manufactured cigarettes employ a built-in filter to reduce the amount of nicotine, tetrahydrocannabinol, tar, resin, smoke, and particulate matter that a smoker inhales when a cigarette is burned. Industrially manufactured filters are designed to not create appreciable resistance to air flow therethrough and may comprise filtering various materials packed to a predetermined length, such as approximately thirty percent of a cigarette&#39;s length. 
     Although it is common now to smoke a tobacco cigarette with a built-in filter, when it comes to cannabis, such industrially produced cigarettes are not broadly available. One convenient method for smoking cannabis is to hand-roll loose cannabis stock into a self-made cigarette. Unfortunately, the resulting ‘joints’ have uneven burn characteristics, are harsh to the lungs, and deliver an unpredictable dose of cannabinoids. Cannabinoid dosing will depend on how loose the roll is, the size of cannabis particles, puff volume, and how uniformly cannabinoids are distributed throughout the cannabis product. Additionally, the smoldering cigarette may shed burning coals, causing a fire hazard. 
     Stand-alone smoke filters are therefore frequently deployed to protect the smoker from harmful substances of cannabis smoke. Such filters need to be placed in series with burning cannabis, such as a self-made cigarette. A combination of a self-rolled cigarette and a filter may be retained together by a conventional cigarette holder. However, rigid conventional cigarette holders are incapable of accommodating self-rolled cigarettes of various sizes on one end and a variety of separately manufactured filters on the other. The need therefore exists for a universal smoking implement capable of accepting a range of cigarettes and filters on both ends thereof. 
     In addition to self-rolled cigarettes, as well as conventional smoking pipes and cigars, a broad selection of other smoking devices are in frequent use, especially in case of cannabis, including hookahs and water pipes, or bongs. These devices may be shared between smokers. To protect an individual smoker against pathogens that can be transmitted from another smoker in this case, there is a need for an individual smoking implement that can be placed at the end of such other devices and separate the smoker from a direct contact with such shared smoking device. To accomplish this, this smoking implement has to be capable of attaching to a variety of sizes of smoking pipes and other smoking devices. 
     Finally, conventional pipes and other smoking appliances have a rigid and typically round mouth piece. To facilitate a better smoking experience, there is a need for a mouthpiece with a deformable mouth piece allowing the smoker to adjust its shape so as to not having to struggle to retain a larger diameter smoking appliance or a cigar between the lips in an airtight fashion. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to overcome these and other drawbacks of the prior art by providing a novel smoking implement capable of universally accepting of and attaching to a variety of smoking devices and cigarettes on one side and a filter on the other end thereof. 
     It is another object of the present invention to provide a smoking implement providing at least some basic level of smoke and particulate filtering even without another filter attached thereto. 
     It is a further object of the present invention to provide a universal smoking implement capable of attaching to a smoking appliance so as to provide individual protection for a smoker from exposure to a risk of being in contact with a contaminated surface of such smoking appliance. 
     It is yet a further object of the present invention to provide a universal smoking appliance with adjustable opening that can be deformed into a desired shape for best smoking experience. 
     The universal elastic smoking implement of the invention may be generally made from an elastically resilient material so as to allow both ends thereof to repeatedly expand outwards and surround one or two of the inserts therein for secure airtight attachment thereto. Such inserts on one side may include a variety of sizes of the tubular container with a burning smoking material such as cigarettes, cigars and other smoking devices, and on the other side these inserts may include a range of smoke filters. 
     One or both ends of the universal implement may further include a malleable insert to allow the user to change the shape of the implement to suit a personal preference.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION 
     The following description sets forth various examples along with specific details to provide a thorough understanding of claimed subject matter. It will be understood by those skilled in the art, however, that claimed subject matter may be practiced without one or more of the specific details disclosed herein. Further, in some circumstances, well-known methods, procedures, systems, components and/or circuits have not been described in detail in order to avoid unnecessarily obscuring claimed subject matter. In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure. 
       FIGS. 1-8  illustrate the first embodiment 100 of the present invention.  FIG. 1  shows a general perspective side view of the smoking implement  100 . For the purposes of this description, the terms “implement”, “smoking implement”, and “implement for smoking” are used interchangeably and have the same meaning. The smoking implement  100  has a generally tubular body and includes a generally smaller diameter first opening at a mouthpiece end  110  located on the opposite side from a generally larger second opening at a smoking end  120 . An external groove  102  may be located closer to the mouthpiece end  110  and used to help indicating for the smoker how to identify a shorter mouthpiece end  110  from a longer smoking end  120 . 
     The generally tubular body of the smoking implement  100  may be made from a single elastic material. It may be beneficial to use a thermo-insulating, biocompatible elastic material so as to assure a safe contact with the smoker&#39;s lips and to avoid a sensation of cold upon touching the implement. In embodiments, the selection of the suitable material may be made with consideration of a melting temperature thereof, which may be selected to be above the expected temperature of the burning smoking material—so as to avoid melting or another distortion or damage of the implement during use. 
     Various individual colors and color mixtures may be added to the material of the implement  100  as well as various external patterns and textures may be made on its external surface (not shown). This may be done to allow several users to easily identify their own smoking implement by appearance or by touch and avoid cross-contamination when a single smoking appliance is shared between several smokers. 
     Finally, a tubular body material with sufficient extent of elasticity may be used to manufacture the smoking implement  100  so as to allow resilient expansion of one or both of its ends as described below to retain a variety of inserts therein in an airtight manner. In embodiments, the material for the smoking implement  100  may be selected with shore A durometer ranging from about 40 to about 70, or in a range from medium soft to medium hard. 
     Polyethylene, polyurethane, polypropylene, natural rubber, silicone, or combinations thereof are all suitable examples of a material for the body of the smoking implement  100 . In addition to above listed considerations, the use of these materials may allow easy washing of the smoking implement  100  with conventional soap and water or even in a dishwasher to remove smoking and other stains therefrom. 
     In further embodiments, more than one material may be used for the construction of the smoking implement  100 . For example, the inner portion of the implement  100  may be made from a first softer material which may be used to increase the strength of the friction fit upon positioning of an insert therein. The outer portion of the smoking implement  100  may be made from a second stiffer material, that may provide for a better touch sensation for the smoker. Selecting such first and second material from the same general chemical family may be advantageous for their secure bond to each other. 
     The tubular body of the smoking implement  100  may be manufactured using conventional polymer production techniques including molding, overmolding, insert molding, vacuum forming, casting, etc. as the invention is not limited in this regard. To facilitate easy manufacturing, the design of the smoking implement  100  may include its internal portions to be smallest in diameter in the central portion of the implement and gradually increase in diameter towards one or both ends thereof. That approach would make the design easier to mold using conventional manufacturing techniques as described above. 
       FIG. 2  shows various internal portions of the smoking implement  100  that are now described in greater detail. The mouthpiece end  110  may be generally designed to accommodate a variety of smoke filters at least partially inserted from the right side of the smoking implement as shown in the drawing. Such smoking filters are produced by a variety of manufacturers. Filters generally comprise a rigid cylindrical housing containing a smoke filter material. The filter housing may include an opening on both sides thereof so as to allow the smoker to apply suction on one side of the filter and draw cigarette smoking therethrough from the other end. Typically, such smoke filters are provided as tubes with an external diameter ranging from about 6 mm to about 9 mm. 
     The mouthpiece  110  may be designed to accept inside thereof a range of smoke filter diameters starting at about 6 mm and extending to about 9 mm—so as to accommodate a majority of such smoke filters available on the market. The internal portion of the mouthpiece  110  may include a first internal mouthpiece stage  114  extending to a second internal mouthpiece stage  112  located serially in line with the first mouthpiece stage  114 . The smaller diameter first mouthpiece stage  114  may be positioned closer to the central region of the smoking implement  100  and may include a tapered or generally cylindrical inner surface  114 ′ with a diameter less or at about 6 mm. The first stage  114  is therefore designed to accept smaller “slim” smoke filters of about 6 to about 7 mm in diameter. Retention of such smoke filter in an airtight manner may be accomplished by a simple friction or press fit as the elastic material of the smoking implement  100  “grabs” the hard surface of the smoke filter once sufficiently expanded to match the filter&#39;s external diameter as a result of pushing the smoke filter inside the body of the smoking implement  100 . The length of the first stage  114  and the second stage  112  may be selected such that together both stages  114  and  112  are shorter than the length of the standalone smoke filter. In embodiments, such combined length may be about 20 mm. In this case, the remaining portion of the smoke filter protruding outside the smoking implement  100  may be used to serve as a mouthpiece for the smoker. In addition, the protruding portion of the smoke filter may be used to hold and remove the smoke filter from the smoking implement  100  after its use. 
     The second internal mouthpiece stage  112  of the mouthpiece end  110  may be sized to have a larger internal diameter that the first mouthpiece stage  114  in order to accept a larger smoke filter, with this internal diameter ranging from about 8 mm to about 9 mm. Such larger or “regular” filter may be inserted inside the second mouthpiece stage  112  and be retained therein via a press fit with its internal surface  112 ′. A short and tapered first step transition  113  may be made between the first mouthpiece stage  114  and the second mouthpiece stage  112  so as to direct the slim filters towards the center of the first mouthpiece stage  114  after traversing the second mouthpiece stage  112 . 
     While those skilled in the art would appreciate that a single mouthpiece stage having a tapered design of the mouthpiece end  110  may be created to span the entire range of smoke filter diameters, it would be less advantageous to do so as such design would necessarily have to have a greater length than the two-stage design of the invention. Making the smoking implement too long with a single tapered mouthpiece end may have a disadvantage to running out of length for a smoke filter, in which case smaller sized smoke filter may have to be completely inserted into the depths of the mouthpiece end  110  of the smoking implement  100 . Not only this is difficult to do by hand, but it would also complicate the removal of the smoke filter from the smoking implement  100  after its use is finished. 
     A screen  130  may be positioned inside the central area of the smoking implement  100  between the mouthpiece end  110  and the smoking end  120 , see  FIGS. 3, 4, and 5 . Such screen may be made using metal such as steel, aluminum, copper, or brass. In embodiments, the screen may be insert-molded inside the smoking implement  100 . In other embodiments, the screen  130  may be simply inserted and retained inside the smoking implement  100 , in which case it may also be removed if needed—for example for replacement purposes. The pore size of the screen  130  may be selected to be from about 0.5 mm to about 1.5 mm. In embodiments, the pore size may be selected to be about 0.5 mm; 0.6 mm; 0.7 mm; 0.8 mm; 0.9 mm; 1.0 mm; 1.1 mm; 1.2 mm; 1.3 mm; 1.4 mm; 1.5 mm or any size inbetween. The main purpose of the screen  130  is to retain large particles that can be liberated during the burning of the smoking material—so as to prevent these particles from traveling to the smoker&#39;s lungs. These particles may include resin clumps and droplets, burned flower remains, ash, etc. Importantly, the screen  130  has to be designed so as not to create any significant resistance to airflow. Hard to inhale smoking device is not desired as it causes a need for deep aspiration during the smoking process. Such deep aspiration makes smoking difficult and strains the chest muscles of the smoker. To accomplish the ease of use, the total available cross-section of the air passage through the screen  130  may be selected to be at least 2 mm 2 , at least 2.5 mm 2 , at least 3 mm 2 , at least 3.5 mm 2 , at least 4 mm 2 , or even larger. 
     The diameter of the round screen  130  may be about 5 mm as this is the narrowest portion of the smoking implement. In embodiments, the screen  130  may not be orthogonal to the longitudinal center line of the smoking implement. It may be positioned at an oblique angle, for example at 45 degrees, 60 degrees, 75 degrees or any angle inbetween about 45 degrees and about 90 degrees to the center line. In that case, the screen may be formed in the shape of an oval rather than being round as seen in the drawings. The advantage of the oval screen design is an increase in the surface area of the screen as compared to the round screen design. In that case, larger number of smaller diameter pores may be provided on the screen  130  so as to reduce the resistance to air flow therethrough while preventing particles from going across the screen  130  and towards the smoker&#39;s lungs. 
     As the screen  130  is positioned generally in the central region of the smoking implement  100 , it also serves as a natural mechanical stop for inserts therein from both ends of the implement. Not only the screen  130  acts as a natural limit for positioning various inserts inside the implement  100  such as smoke filters and tubular containers with slowly burning smoking material, it also helps to prevent dislodging of one insert by positioning another one from the opposite end of the smoking implement  100 . 
     A further purpose of the screen  130  is to serve as a rigid reinforcement component so as to prevent collapse of the elastic central region of smoking implement when compressed by the fingers of the smoker, especially when used with larger size inserts, which leave the central region of the implement empty. 
     The internal region of the smoking end  120  may also be made to be cylindrical or with a gradual taper as seen in  FIG. 2  and  FIG. 5 . The diameter of the internal surface  118  may be about 7 mm at the transition point from the entry taper  122 —and may reduce to about 6 mm towards the central region of the smoking implement  100 . This sizing may be sufficient to retain a number of smoking devices as well as cigarettes. One example is seen in  FIG. 6 , which shows an assembly of an e-cigarette  160  (shown in dotted lines as it does not constitute a part of the present invention) inserted into the smoking end  120  of the implement  100  and a smoke filter  160  (also shown in dotted lines) inserted into the mouthpiece end  110  of the implement  100  with the other end of the filter  160  protruding outside the first opening of the mouthpiece end  110 . 
     Between the inner surface  118  of the smoking end  120  and the screen  130  there may be provided an attachment region  116 . The internal surface of the attachment region  116  may have an internal size larger than that of the inner surface  118 . In embodiments, the shape of the attachment region  116  may be made round or tapered. This region may be included in the design of the smoking implement  100  for the purposes of a resiliently sliding over and securely attaching to a custom smoking device having a correspondingly mating external shape of its endpiece. Sliding of the smoking implement  100  over such endpiece with a predetermined geometry and locking in place using the attachment region  116  will allow retention of the implement  100  over such smoking device. In this case, the smoking implement  100  may serve as a removable personal smoking mouthpiece—to be used with or without the filter inserted on the other end thereof. 
       FIGS. 7 and 8  show a further variation of the first embodiment of the invention in which the shape of the mouthpiece end  110  of the smoking implement  100  may be adjusted and reshaped by the smoker to suit his or her individual preferences. To achieve this desired reshaping ability, the mouthpiece end  110  may have a malleable insert  135  embedded inside thereof and configured to be deformed or bent manually and retain its shape after such bending. A metal band or an O-ring may be used for such purpose in one example. Any malleable metal will be suitable to make the insert  135  from, such as copper, brass, steel or aluminum.  FIG. 8  shows a perspective view of the smoking implement of the invention after the mouthpiece end  110  has been reshaped to have a flatter oval opening. 
     In further embodiments, the malleable insert may not be a single-piece solid O-ring spanning all the way around the entire circular periphery of the mouthpiece end of the implement. Such malleable insert may in this case comprise two malleable semi-circles located opposite each other to make up a full circular shape between the two of them. That design will allow the opening of the mouthpiece end  110  to still expand in places not covered by the metal semi-circles and accept a filter insert of a diameter larger than the internal diameter of the mouthpiece end  110 . Further shapes of the malleable insert  135  having interruptions of suitable sizes along the circular periphery of the mouthpiece opening to allow for its outward resilient expansion are contemplated by the present invention. 
     The second embodiment of the present invention is now described in greater detail and is illustrated in  FIG. 9  through  FIG. 16 .  FIG. 9  shows a partial cross-section of the smoking implement  200  defining a mouthpiece end  210  and an opposite smoking end  220  with a screen  230  located in the central region of the implement inbetween thereof. The mouthpiece end  210  may be made using a similar two-stage design as that of the first embodiment of the invention described above. 
     The smoking end  220  may be designed to accommodate a broader range of cigarettes, cigars, smoking pipes and other smoking accessories than that of the first embodiment. To accomplish this, the smoking end  220  may be made to have multiple internal smoking stages of increasing diameter starting with the smallest diameter first internal smoking stage  222  located near the central region of the smoking implement  200 . The internal geometry of the first internal smoking stage  222  may be generally circular or gradually tapered with an increasing flare towards the second opening of the smoking end  220  of the implement  200 . The starting diameter near the screen  230  may be about 5 mm, which may increase to about 6 mm or about 7 mm away from the screen  230 . The first smoking stage  222  may be designed to accept an insert of a slim cigarette of other small smoking devices. 
     At least one additional internal smoking stage may be provided with a diameter larger than that of the first smoking stage  222 . As seen in  FIGS. 9, 10, and 11  a second internal smoking stage  224  may be provided with internal diameters of about 7 mm, 8 mm, 9 mm, 10 mm, 11 mm or any diameter inbetween. This stage may be separated from the first smoking stage  222  by a second tapered step transition  223 . The second smoking stage  224  may be designed to snugly accept medium sized smoking devices such as small cigars, mouthpiece portions of smaller smoking pipes, e-cigarettes, etc. 
       FIG. 12  shows one example of an assembly comprising a smoking filter  250  (shown in dotted lines) partially inserted into the mouthpiece end  220  of the smoking implement  200 —with a self-rolled cigar  260  (shown in dotted lines) partially inserted into the second smoking stage  224  of the implement  200 . 
     A third internal smoking stage  226  may also be provided at the second opening of the smoking end of the implement  200 . This third smoking stage  226  may be the largest for its internal diameter and may be separated from the second smoking stage  224  by a third tapered transition  225 . The internal diameter of the cylindrical or gradually tapered third smoking stage  225  may be selected to be about 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm or any size inbetween as the invention is not limited in this regard. The third smoking stage  226  may be designed to accommodate the airtight insertion of larger smoking devices such as cigars, pipes, mouthpiece portions of bongs etc. In an exemplary illustration seen in  FIGS. 13 and 14 , a smoking pipe  270  (shown in dotted lines) is partially inserted and retained by the third stage  226  of the smoking implement  200 , while a smoke filter  250  (also shown in dotted lines) is partially inserted into the mouthpiece end  210  on the other side thereof. 
     In embodiments, further smoking stages of even larger diameters may be provided to allow insertion and friction-based retention of a variety of other even larger smoking device as the invention is not limited in this regard. 
     As discussed above, making either the mouthpiece end  210  or the smoking end  220  with multiple stages of stepped up diameters allows the entire design of the smoking implement  200  to be as short as possible while accommodating a broad range of sizes for both the smoke filters as well as tubular containers with burning smoking material. 
     As would be appreciated by those skilled in the art, the smoke filter  250  may or may not be used by the smoker. In case when there is no filter present, the smoker takes the implement  200  and retains in the mouth by using the lips placed around the smoking implement  200 . To facilitate an easier retention of the smoking implement  200  in the smoker&#39;s mouth for a better smoking experience, the implement  200  may feature a malleable insert component  235  embedded in the elastic mouthpiece end  210  of thereof—see  FIG. 15 . The design and use of the malleable insert  235  may be similar to that described above for the first embodiment of the invention. The malleable insert  235  allows the smoker to manually change the shape of the opening of the mouthpiece end  210  from initially round to that of an oval—see  FIG. 16 . An oval shape may be preferred by the smoker in case when no filter is inserted into the implement  200 . 
     In further embodiments, the internal surfaces of the smoking implement may not be designed as smooth and round. Various generally longitudinal ribs and bumps (not shown in the drawings) may be added so as to increase the ability of the smoking implement to retain various smoke filters and smoking devices upon their insertion thereinto. 
     It is contemplated that any embodiment discussed in this specification can be implemented with respect to any method of the invention, and vice versa. It will be also understood that particular embodiments described herein are shown by way of illustration and not as limitations of the invention. The principal features of this invention can be employed in various embodiments without departing from the scope of the invention. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, numerous equivalents to the specific procedures described herein. Such equivalents are considered to be within the scope of this invention and are covered by the claims. 
     All publications and patent applications mentioned in the specification are indicative of the level of skill of those skilled in the art to which this invention pertains. All publications and patent applications are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. Incorporation by reference is limited such that no subject matter is incorporated that is contrary to the explicit disclosure herein, no claims included in the documents are incorporated by reference herein, and any definitions provided in the documents are not incorporated by reference herein unless expressly included herein. 
     The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.” The use of the term “or” in the claims is used to mean “and/or” unless explicitly indicated to refer to alternatives only or the alternatives are mutually exclusive, although the disclosure supports a definition that refers to only alternatives and “and/or.” Throughout this application, the term “about” is used to indicate that a value includes the inherent variation of error for the device, the method being employed to determine the value, or the variation that exists among the study subjects. 
     As used in this specification and claim(s), the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) are inclusive or open-ended and do not exclude additional, unrecited elements or method steps. In embodiments of any of the compositions and methods provided herein, “comprising” may be replaced with “consisting essentially of” or “consisting of”. As used herein, the phrase “consisting essentially of” requires the specified integer(s) or steps as well as those that do not materially affect the character or function of the claimed invention. As used herein, the term “consisting” is used to indicate the presence of the recited integer (e.g., a feature, an element, a characteristic, a property, a method/process step or a limitation) or group of integers (e.g., feature(s), element(s), characteristic(s), propertie(s), method/process steps or limitation(s)) only. 
     The term “or combinations thereof” as used herein refers to all permutations and combinations of the listed items preceding the term. For example, “A, B, C, or combinations thereof” is intended to include at least one of: A, B, C, AB, AC, BC, or ABC, and if order is important in a particular context, also BA, CA, CB, CBA, BCA, ACB, BAC, or CAB. 
     Continuing with this example, expressly included are combinations that contain repeats of one or more item or term, such as BB, AAA, AB, BBC, AAABCCCC, CBBAAA, CABABB, and so forth. The skilled artisan will understand that typically there is no limit on the number of items or terms in any combination, unless otherwise apparent from the context. 
     As used herein, words of approximation such as, without limitation, “about”, “substantial” or “substantially” refers to a condition that when so modified is understood to not necessarily be absolute or perfect but would be considered close enough to those of ordinary skill in the art to warrant designating the condition as being present. The extent to which the description may vary will depend on how great a change can be instituted and still have one of ordinary skilled in the art recognize the modified feature as still having the required characteristics and capabilities of the unmodified feature. In general, but subject to the preceding discussion, a numerical value herein that is modified by a word of approximation such as “about” may vary from the stated value by at least ±1, 2, 3, 4, 5, 6, 7, 10, 12, 15, 20 or 25%. 
     All of the devices and/or methods disclosed and claimed herein can be made and executed without undue experimentation in light of the present disclosure. While the devices and methods of this invention have been described in terms of preferred embodiments, it will be apparent to those of skill in the art that variations may be applied to the devices and/or methods and in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the invention as defined by the appended claims.
