Title: Method and device for protecting beer and other beverages from light energy

Description:
This Nonprovisional Patent Application is a Continuation-in-Part Patent Application to Nonprovisional Patent Application Ser. No. 63/134,474 as filed on Jan. 6, 2020, by Inventor Nicholas Peter Pavlina. Provisional Patent Application Ser. No. 63/134,474 is hereby incorporated into its entirety and for all purposes into the present disclosure. 
    
    
     FIELD OF THE INVENTION 
     The field of the invention is related to beverage quality maintenance, and specifically to protection of beer and other beverages from the chemical reaction effects of prolonged exposure to direct sunlight. 
     BACKGROUND OF THE INVENTION 
     The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions. 
     It is well known that certain varieties of craft beer and other similar beverages can turn sour (or get “skunked”, as this is sometimes called) if exposed to too much light. This phenomenon resulting from a natural chemical process is a key reason why this type of beverage is generally packaged and sold in opaque metal cans or dark brown glass bottles, as opposed to clear or green glass containers which expose the contents to more light. However, a customer ordering a craft beer on tap at a taphouse, brewery, or restaurant may encounter the same “skunking” problem simply by enjoying a pint outdoors during the day, and may not be wary enough to keep the beer out of the sun. 
     Therefore, there is a long-felt need to improve a craft beer dining experience by providing additional protection against skunking of tap craft beer in particular by exposure to light. Especially given the present public health imperative to reduce indoor dining and encourage outdoor dining instead, there has perhaps never been a better time to provide an improved experience of enjoying a craft beer outside in the sun. 
     SUMMARY OF THE INVENTION 
     Towards these and other objects of the method of the present invention (hereinafter, “the invented method”) that are made obvious to one of ordinary skill in the art in light of the present disclosure, what is provided is a sun shade for placing around or above one&#39;s glass of craft beer to better protect the beer from skunking by exposure to light. 
     In certain preferred embodiments and applications, the device of the present invention (hereinafter, “the invented device”) may consist of a base for placement upon a table or other surface, a back piece perpendicular to the base, and a top piece coupled to the back piece such that the top may be positioned over the top of a glass or tankard and provide a physical shield between the drink and light originating from a substantively overhead source such as but not limited to a ceiling light or the sun. In certain preferred embodiments, the device may consist of a shaped single-piece object that can be utilized in a restaurant or taproom setting in a similar fashion to a utensil or condiment container, such as but not limited to handing the device to a customer along with their purchased beer, or delivering the device to a customer&#39;s table or seat along with their purchased beer, perhaps with the understanding that the device will be left at the table or otherwise returned when the customer leaves. In preferred embodiments, the device might be shaped to stand on a table or flat surface and provide an overhanging opaque or light-restricting element at a suitable height for placing of the beverage safely underneath. 
     The invented device might be made of any suitable material or combination of materials as known in the art or subsequently discovered to be suitable, such as but not limited to aluminum metal, other metal or metal alloys, plastic, glass, ceramic, or wood. It is noted that at least the overhanging element is preferably made of a material that provides shade or reduces light passing through; this may be an entirely opaque material, but certain non-opaque materials, such as but not limited to the dark brown or green varieties of beer bottle glass used for the same anti-skunking purpose in packaged beer, may also be suitable for providing at least reduced light exposure. The current preferred prototypes, on which the Figures drawings of this disclosure are generally based, are each constructed with a single piece of shaped metal, but embodiments comprised of multiple coupled pieces or materials are obvious variations on the essential concept of the invention. No limitation of suitable materials for construction of the invented device should be assumed except as specifically limited by the claims. 
     The examples of the invented device as presented in the disclosure are of a certain size suitable for fitting over or around most beer glasses, but it should be noted that the invented device is not limited to the size of the presented examples disclosed herein, and no limitation of size or scale should be assumed or construed except as specifically limited by the claims. 
     Further, while the invention is generally suited to physically shielding beer and other beverages that might be damaged by exposure to light, the invented device may also be suited to provide the additional possible benefit of a cover or partial cover for the top of a drink glass which may discourage the evaporation of alcohol or carbonation from a beverage, or keep a warm drink warm for longer, by partially trapping steam and/or air pressure above the surface of the beverage. 
     Certain preferred embodiments of the invented device may include a handle, such as but not limited to an aperture through the upright section that may fit a few fingers or a hand, or even a grip extension for someone to use in similar fashion to the way one might use the handle of a mug or tankard. The handle may be gripped for moving or using the device, and may also be used to hang the device on a hook, as a point to fasten a rope or cord around, or similar applications of handles as known in the art. 
     Additional possible add-on features for the invented device are numerous and obvious. For example, further alternate preferred embodiments of the invented device may be foldable or collapsible, such as for portability. The invented device may have a flat ‘clip’ or clamp attached, such as for holding a piece of paper; in a restaurant setting, a customer might be served a craft beer with the invented device, the invented device having the check, a few napkins, or some promotional material thoughtfully clipped on for the customer&#39;s convenience. The invented device might also be decorated with a logo, picture, or other design, such as to identify the owner or as a self-expression by the owner, such as but not limited to a personal beer protector bearing one&#39;s initials, the logo of the taphouse the device belongs to or originated from, or the insignia of one&#39;s favorite sports team. The device may be foldable or collapsible, for convenience of portability. The invented device might be modified in shape, such as for aesthetic effect or for providing of additional features. 
     Certain other alternate preferred embodiments comprise a translucent vessel containing a liquid beverage; and a shield that is as least partially screening of light energy, the shield positioned relative to the vessel to limit the exposure of the liquid beverage to light energy, and wherein the beverage may comprise beer. 
     This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

     DETAILED DESCRIPTION OF DRAWINGS 
     In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications. 
     It is to be understood that this invention is not limited to particular aspects of the present invention described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims. Methods recited herein may be carried out in any order of the recited events which is logically possible, as well as the recited order of events. 
     Where a range of values is provided herein, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range, is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits ranges excluding either or both of those included limits are also included in the invention. 
     Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, the methods and materials are now described. 
     It must be noted that as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. It is further noted that the claims may be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as “solely,” “only” and the like in connection with the recitation of claim elements, or use of a “negative” limitation. 
     When elements are referred to as being “connected” or “coupled,” the elements can be directly connected or coupled together or one or more intervening elements may also be present. In contrast, when elements are referred to as being “directly connected” or “directly coupled,” there are no intervening elements present. 
     Throughout this specification, like reference numbers signify the same elements throughout the description of the figures. 
     Referring now generally to the Figures and particularly to  FIG. 1 ,  FIG. 1  is a line drawing presenting a first embodiment of the invented device (“a first device  100 ”) as used in context. The first device  100  includes a base  102 , a back  104 , and a roof  106 . The first device  100  is placed on a substantively flat surface  108  such as a table, adjacent to a glass  110 , such that the roof  106  is positioned over the top of the glass  110 , thus shading the glass  110  at least partially from light  112  from a light source  114  positioned above the surface  108  that might otherwise ‘skunk’ the beverage in the glass  110 . It is noted that this instance where the beverage is contained in a translucent vessel like the glass  110  is a demonstrative example; the beverage does not need to be in a glass, and may instead be held in a cup, mug, tankard, or other vessel suitable for containing a beverage, and further, if the vessel still exposes the beverage to any light, the present invention may still be useful in sheltering the beverage from light and reducing chance of ‘skunking’. 
     In preferred embodiments, the back  104  stands perpendicular to the base  102 , such that the base  102  can sit firmly upon the surface  108 , and the back  104  can provide suitable elevation for the roof  106  to overhang the glass  110 . It is noted that the height of the device  100  relative to the glass  110  is relevant: if the device  100  is too short, the glass  110  may not fit underneath; if the device  100  is too tall, the efficacy may be reduced, as the shadow of the roof  106  may not fall on the top of the glass; a close fit is ideally preferred, but ideally not to the point of skimming foam off the top of the beverage in the glass  110 . It is further noted that a just-right close fit may provide additional benefits such as partially isolating air pressure on the surface of the beverage and thus reducing heat transfer into the surrounding air or evaporation of carbonation or alcohol. 
       FIG. 1  further includes an XYZ compass  116 , presenting an X axis, Y axis, and Z axis as labeled. The X axis is mutually orthogonal both to the Y axis and to the Z axis. The Y axis is mutually orthogonal to both the X axis and the Z axis. The Z axis is mutually orthogonal to both the X axis and the Y axis. For the purposes of standardizing terminology in this disclosure, the X axis is the ‘front-to-back’ dimension relative to the device  100 , and runs parallel to the surface  108 . The point of the roof  106  most distant from the back  104  along the X axis is considered the front of the device  100 . The Y axis is the dimension of ‘up and down’, such that the back  104  runs parallel or mostly parallel (allowing for aesthetic or stylized variation) to the Y axis, and the Y axis is substantively orthogonal to the surface  108 , such that the base  102  rests on and against the surface  108 , and the roof  106  is positioned at the end of the device  100  furthest from the base  102  along the Y axis. The Z axis is the ‘side-to-side’ dimension, and runs parallel to the surface  108  and orthogonal to the other two axes. All instances of the XYZ compass  116  appearing in other Figures follow the same conventions stated above. 
     Referring now generally to the Figures and particularly to  FIG. 2A ,  FIG. 2A  is a line diagram of a prototype of the invented device  100  of  FIG. 1 , presenting a front profile view. It is noted that shading is selectively included in this line diagram to better represent this three-dimensional object, such as making clearer that the corner between the back  104  and roof  106  is an ‘inside’ corner, with the roof  106  facing downward and substantively orthogonal to the back  104 . 
     Referring now generally to the Figures and particularly to  FIG. 2B ,  FIG. 2B  is a line drawing of the invented device  100  of  FIG. 2A , presenting a side profile view. It is noted that shading of the roof  106  is again utilized to decrease any visual ambiguity by indicating that the underside of the roof  106 , facing downward and thus shadowed, and the top side of the base, facing upward and thus illuminated, are in view. 
     Referring now generally to the Figures and particularly to  FIG. 2C ,  FIG. 2C  is a line drawing of the invented device  100  of  FIG. 2A , presenting a top view. It is noted that the back  104  is barely visible in this view from directly above the invented device  100 . 
     Referring now generally to the Figures and particularly to  FIG. 3A ,  FIG. 3A  is a line drawing of a second embodiment of the invented device (“a second device  300 ”), presenting a side view. This alternative model of the invented device  300  includes a base  302  with a ‘folded over’ clip element  302 A, a back  304 , and a roof  306 . The clip element  302 A may provide extra base  302  stability or ballast, and may also serve as a clip feature into which a paper, such as a diner&#39;s check, a small menu, a promotional brochure, a few napkins, or something similar might be placed when a glass  110  of craft beer is served to a diner along with the invented device  300 . 
     Referring now generally to the Figures and particularly to  FIG. 3B ,  FIG. 3B  is a line drawing of the second embodiment of  FIG. 3A , presenting a top view. 
     Referring now generally to the Figures and particularly to  FIG. 4A ,  FIG. 4A  is a line drawing of a third embodiment of the invented device, presenting a side profile view. This embodiment includes a base  402 , a back  404 , a roof  406 , and further includes a dip  404 A to the back, a shape which may provide additional benefits of design such as conserving space while allowing a larger base  402 , or providing a built-in ‘hook’ shape for carrying or storing the device  400 . This embodiment also has the base  402  positioned substantively underneath the roof  406 . This may also conserve some space on a crowded table, or allow a server to carry and serve the glass  110  already placed ‘inside’ the device  400  rather than handle the device and glass as two items, though this may increase risk of toppling or spilling the glass  110 . The side panels presented in  FIGS. 7A through 9B  might be useful in providing more stability in that application of carrying the beverage inside the invented holder, or a railing feature at least partially encircling the position of the glass might also offer improved stability. It is noted that shading is included in this image to reduce visual ambiguity, such as shadowing in the corner between the back  404  and the roof  406  to visually indicate an inside corner. 
     Referring now generally to the Figures and particularly to  FIG. 4B ,  FIG. 4B  is a line drawing of the third embodiment of  FIG. 4A , presenting a front view. It is noted that shading is added to reduce visual ambiguity in a line drawing of a three-dimensional object, such as by indicating that the underside of the roof  106  and the sloped face of the dip  404 A are facing downward or partially downward. 
     Referring now generally to the Figures and particularly to  FIG. 4C ,  FIG. 4C  is a line drawing of the third embodiment of  FIG. 4A , presenting a bottom view. It is noted that the back  404  and the roof  406  are partially visible from this angle, and labeled accordingly. 
     Referring now generally to the Figures and particularly to  FIG. 5A ,  FIG. 5A  is a line drawing of a fourth embodiment of the invented device, presenting a side view. This fifth device  500  includes a base  502 , a back  504 , and a roof  506 . This compact and simple variation includes the feature of the roof  506  positioned directly above the base  502 , allowing the fifth device  500  to take up minimal space. 
     Referring now generally to the Figures and particularly to  FIG. 5B ,  FIG. 5B  is a line drawing of the fourth embodiment of  FIG. 5A , presenting a bottom view. 
     Referring now generally to the Figures and particularly to  FIG. 5C ,  FIG. 5C  is a line drawing of the fourth embodiment of  FIG. 5A , presenting a top view. This image further presents the optional feature of a graphic  508  such as a logo positioned on the top panel of the invented device facing upward. It is noted that the graphic  508  may be any kind of image considered appropriate to place on the invented device. One example might be a signature, trademark, logo, or other brand indicator belonging to the establishment to which the invented device belongs, so that a taphouse might have a collection of these devices with matching logos on them, much like trays, glasses, napkin holders, or other such elements. Another application of this might be providing customization for a personal device, such that an avid beer drinker might purchase and carry their own and have it personalized, such as with their name, favorite sports team, or a graphic similar to what one might put on a t-shirt, bumper sticker, or mug. The graphic  508  might be positioned elsewhere on the device besides the top, such as the graphic  508  of  FIG. 5D  positioned on the back of the device. The graphic  508  might be affixed or drawn onto the device in a variety of different ways allowing for different aesthetics, including but not limited to pasting on a sticker, painting, etching, welding, burning, or adding a ‘jacket’ bearing the logo made out of some other material. It is noted that the graphic  508  might also consist of apertures through the device, in the manner of a stencil; a lot of potential for creativity in aesthetic design is available here, and this disclosure of some approaches that come to mind should not be construed as limiting in scope; no matter how the invented device is decorated, it will generally remain an instance or embodiment of the invented device. 
     Referring now generally to the Figures and particularly to  FIG. 5D ,  FIG. 5D  is a line drawing of the fourth embodiment of  FIG. 5A , presenting a rear view. This image further presents the optional feature of the graphic  508  of  FIG. 5C , positioned at an alternative location such as the back of the device. It is noted that the graphic  508  might be positioned elsewhere on the device besides the top or back, and no limitation as to the positioning of the graphic  508  is intended by providing of these examples. 
     Referring now generally to the Figures and particularly to  FIG. 5E ,  FIG. 5E  is a line diagram of the fourth embodiment of  FIG. 5A , presenting physical dimensions of height h, width w, depth d, and thickness t. While the invented device is not limited to a specific size and may be scalable as deemed practical or advantageous, the invented device is generally preferred to be of a size to stand slightly taller and wider than a standard-sized beverage glass  110 , so as to fit around and over the glass and provide shade. Some exemplary measurements for the fourth device  500 , as an illustrative example, may include the following. Height h from the bottom of the base  502  to the top of the roof  506  may preferably be within the range of between 1 inch and 24 inches. Width w from the back  504  to the frontmost point of the roof  506  may preferably be within the range of between 1 inch and 12 inches. Depth d from one side to the other along the Z axis may preferably be within the range of between 1 inch and 12 inches. Thickness t from one face to the opposite face of a piece of material such as the back  504  may preferably be within the range of between 1/1000th of an inch and 3 inches. 
     Referring now generally to the Figures and particularly to  FIGS. 6A, 6B, and 6C ,  FIGS. 6A, 6B, and 6C  present various embodiments of the invented device further including a variety of possible handles that might be included as additional features to any embodiment of the invented device.  FIG. 6A  presents a first alternative type of handle (“a first handle  600 ”) consisting of an aperture through the material of the back  104 .  FIG. 6B  is a line drawing presenting the invented device of  FIG. 1  further including a second alternative type of handle (“a second handle  602 ”) consisting of an aperture through the material of the back  104 . An aperture serving as a handle for the invented device might take a wide variety of shapes, either practical or decorative, of which the first handle  600  and the second handle  602  are only two representative examples.  FIG. 6C  is a line drawing presenting the first device of  FIG. 1  further including a third alternative variety of handle (“a third handle  604 ”). This handle might be coupled to the back of the device as presented, providing a hand grip similar to a mug or tankard. It is understood that any embodiment of the invented device, including the first device  100  of  FIG. 1 , the second device  300  of  FIG. 3A , the third device  400  of  FIG. 4A , the fourth device  500  of  FIG. 5A , the sixth device of  FIG. 10A , the seventh device of  FIG. 11A , might further include a handle such as one of the handles presented in  FIGS. 6A, 6B, and 6C  or another suitable handle as known in the art or deemed appropriate in design, of which these are only a few possible examples. 
     Referring now generally to the Figures and particularly to  FIG. 7A ,  FIG. 7A  is a line drawing diagram presenting the third device  400  further including a side panel  700 . The side panel  700  may provide further shade area coverage or protection from light for the beverage glass  110 . The side panel  700  also may be decreased or increased in size and/or area coverage, and is preferably opaque or otherwise adapted to provide shade from light. The side panel may be coupled permanently as part of the device  400 , or may be detachably coupled, such as by sliding into grooves positioned on the roof  406  and base  402  or being coupled by other fastening means as known in the art. The side panel may be a rigid element, such as a sheet of metal or plastic, but may also be flexible or clothlike, such as with the device  400  providing a rigid ‘framework’ to support the shape of the side panel  700 . One notes that all components of the invented device are preferably washable, as spills do occasionally happen and cleanliness is important in a setting where food and drink are prepared and consumed. 
     Referring now generally to the Figures and particularly to  FIG. 7B ,  FIG. 7B  is the line drawing diagram presenting the third device  400  further including the side panel  700 , and additionally presenting the glass  110  positioned within the device  400  as a reference indicator. The side panel  700  may be positioned on either side of the device, i.e. as shown or on the opposite side which in this image would partially conceal the glass  110  from view. Some embodiments may even include the panel  700  as positioned on the front (curved, opposite the back  404 ), such that the device forms a closed loop with the sides open. There may be side panels  700  covering more than one side, or curving around to cover one side and part of another. Additionally, while  FIGS. 7A and 7B  present the side panel  700  as added to the third device  400 , any embodiment of the invented device might include the side panel  700  as an additional feature, and the third device  400  was used here only as an example for the purpose of illustration. It is noted that the side panel  700  may also provide additional stabilization if the device  400  were to be picked up and moved with the glass  110  in place. 
     Referring now generally to the Figures and particularly to  FIG. 8A ,  FIG. 8A  is a diagram presenting the third device  400  additionally including an overhang  800 . The overhang  800  may be an additional partial sheet or panel for providing additional light-blocking, or an extension of the roof  406  that ‘curves’ down to extend the shielding surface. The overhang  800  may be positioned on the front, as shown, but may also be positioned on a side, or curve around the front and part of a side. 
     Referring now generally to the Figures and particularly to  FIG. 8B ,  FIG. 8B  is a diagram presenting the third device  400  with overhang  800 , additionally presenting the glass  110  positioned within the device  400  as a reference indicator. It is noted that the overhang  800  may also provide additional stabilization if the device  400  were to be picked up and moved with the glass  110  in place. 
     Referring now generally to the Figures and particularly to  FIG. 9A ,  FIG. 9A  is a diagram presenting the third device  400  with both the side panel  700  and the overhang  800  in combination. 
     Referring now generally to the Figures and particularly to  FIG. 9B ,  FIG. 9B  is a diagram presenting the third device  400  with both the side panel  700  and the overhang  800  in combination, additionally presenting the glass  110  positioned within the device  400  as a reference indicator. 
     Referring now generally to the Figures and particularly to  FIGS. 10A and 10B ,  FIGS. 10A and 10B  present a sixth embodiment of the invented device (“a sixth device  1000 ”) which can be folded up. The sixth device  1000  has a base  1002 , a back  1004 , a roof  1006 , and also a set of hinges  1008 . In this embodiment, the base  1002 , back  1004 , and roof  1006  are preferably separate pieces of material, coupled together by mutual coupling to the hinges  1008 , such that when the hinges  1008 A coupling the base  1002  to the back  1004  are rotated, the base  1002  is re-oriented to form a narrower and more acute angle relative to the back  1004  as shown in  FIG. 10B , and such that when the hinges  1008 B coupling the roof  1006  to the back  1004  are rotated, the roof  1006  is re-oriented to form a narrower and more acute angle relative to the back  1004  as presented in  FIG. 10B . In certain preferred embodiments the base  1002  and roof  1006  may fold ‘all the way in’, rather than mostly as shown in  FIG. 10B , such that the device  1000  is substantively flat in a folded-up state; this could be especially useful for storage or travel. In certain preferred embodiments, the hinges  1008  may allow the base  1002  or roof  1006  to rotate all the way around, such that the roof  1006  may be positioned on the opposite side of the back  1004  from the base  1002  (as presented in  FIGS. 10A and 10B ) or both the base  1002  and roof  1006  may be positioned on the same side, as presented in the seventh device  1100  of  FIGS. 11A and 11B . The hinges  1008  may contain components not shown as generally understood as belonging to or used with hinges as known in the art, such as a spring, a central axis or pin around which the hinge rotates, or a locking mechanism to hold the hinge  1008  in a current rotated position. The sixth device  1000  may further include means for locking the device ‘open’ (i.e. usable as a drink shield in accordance with the invented method) or ‘closed’ (i.e. folded up flat for storage). This diagram presents two hinges  1008  at each rotation point; this might easily be single hinges  1008  instead, as presented in  FIGS. 11A and 11B . 
     Referring now generally to the Figures and particularly to  FIGS. 11A and 11B ,  FIGS. 11A and 11B  present a seventh embodiment of the invented device (“a seventh device  1100 ”) which can be folded up. The seventh device  1100  has a base  1102 , a back  1104 , a roof  1106 , and also a set of hinges  1108 . In this embodiment, the base  1102 , back  1104 , and roof  1106  are preferably separate pieces of material, coupled together by mutual coupling to the hinges  1108 , such that when the hinge  1108 A coupling the base  1102  to the back  1104  are rotated, the base  1102  is re-oriented to form a narrower and more acute angle relative to the back  1104  as shown in  FIG. 10B , and such that when the hinge  1108 B coupling the roof  1106  to the back  1104  are rotated, the roof  1106  is re-oriented to form a narrower and more acute angle relative to the back  1104  as presented in  FIG. 11B . In certain preferred embodiments the base  1102  and roof  1106  may fold ‘all the way in’, rather than mostly as shown in  FIG. 11B , such that the device  1100  is substantively flat in a folded-up state; this could be especially useful for storage or travel. In certain preferred embodiments, the hinges  1108  may allow the base  1102  or roof  1106  to rotate all the way around, such that the roof  1106  may be positioned on the same side of the back  1104  as the base  1102  (as presented in  FIGS. 11A and 11B ) or both the base  1102  and roof  1106  may be positioned on opposite sides, as presented in the sixth device  1000  of  FIGS. 10A and 10B . The hinges  1108  may contain components not shown as generally understood as belonging to or used with hinges as known in the art, such as a spring, a central axis or pin around which the hinge rotates, or a locking mechanism to hold the hinge  1108  in a current rotated position. The seventh device  1100  may further include means for locking the device ‘open’ (i.e. usable as a drink shield in accordance with the invented method) or ‘closed’ (i.e. folded up flat for storage). 
     The invented device might be made of any suitable material or combination of materials as known in the art or subsequently discovered to be suitable, such as but not limited to metal, plastic, glass, ceramic, or wood. It is noted that at least the overhanging element is preferably made of a material that provides shade or reduces light passing through; this may be an entirely opaque material, but certain non-opaque materials, such as but not limited to the dark brown beer bottle glass used for the same anti-skunking purpose in packaged beer, may also be suitable for providing at least reduced light exposure. The scope of the invention includes both embodiments comprising multiple pieces of material coupled together and embodiments formed out of a single piece of material. No limitation of suitable materials for construction of the invented device should be assumed except as specifically limited by the claims. 
     The examples of the invented device as presented in the disclosure are of a certain size suitable for fitting over or around most beer glasses, but it should be noted that the invented device is not limited to the size of the presented examples disclosed herein, and no limitation of size or scale should be assumed or construed except as specifically limited by the claims.
