The device is engageable to the bottle or cap by insertion of the cap end of the bottle, into a cavity in the base end, and exerting force along an axial line running through the bottle. A frictional engagement between surfaces of the device and the bottle is achieved which may be enhanced by biasing components.

Description

This application claims the benefit or U.S. Provisional Patent Application Ser. No. 61/486,680, filed May 16, 2011, and incorporated herein in its entirety by reference. The present invention relates to drinking vessels.

BACKGROUND OF THE INVENTION

1. Field of the Invention

More particularly, it relates to a drinking or measuring glass which is configured for a removable engagement with the capped end of a bottle.

2. Prior Art

In the fast paced world of bartending and nightclubs, it is wells known that faster service breeds happier customers and that happier customers tend to leave better tips for the serving staff. Measuring of the pour of alcohol to mixer is the most time consuming portion of providing cocktail service, and can be inhibited by the lack of a measuring vessel for the alcohol portion.

Individuals attending a party or picnic have the same needs for making mixed cocktails, if not an enhanced need since a non professional is generally unable to estimate a proper pour measurement for the alcoholic portion of a mixed drink. Additionally, for the more refined alcohol consuming individuals who enjoy aged or fine liquor, adding such to a mixer may not be their choice of use. However, such users frequently choose to sip a fine alcoholic beverage slowly either straight up or in measured amounts on ice. Additionally, it is well known that college students have a proclivity to inbibe which can require the employment of a measured drinking vessel being handy from which to pour and measure before drinking from the glass.

As a consequence, from professionals to social drinkers, there is a continual need for the easy acquisition of a measured drinking or measuring vessel such as what is conventionally termed a shot glass. This one vessel allows bartenders and amateurs to properly mix the desired ratio of alcohol to mixer, and to simply empty the shot glass should direct consumption in a measured amount be desirable.

Additionally, in any given bar or adult nightclub, one can conventionally find measured drinking vessels such as pint glasses, wine glasses, the occasional champagne flute, and of course, the frequently requested shot glass. Since shot glasses are conventionally small, holding only about 1 ounce to 1.5 ounces of fluid, bartenders and patrons of the like are continually in need of having such shot glasses readily available for both measuring and for direct employment in drinking measured amounts of liquid.

Prior art has shown many attempts to provide shot glasses which double as or are part of the bottle cap for a bottle or the like. US. Pat. App. Pub. 2008/0011710 A1 to Cohn and US. Pat. App. Pub. 2008/0116164 A1 to Dellinger et. al. teach a combined shot glass and bottle cap. The shot glass of Cohn includes a threaded base portion adapted for watertight engagement with the often threaded top of a liquor bottle while Dellinger includes a threaded portion located at the inside top lip area of the shot glass.

However, given the wide variety of manufacturers of liquor and bottles with many having slightly different diameters and different threads, the threaded portions of Cohn and Dellinger are not easily employed even with bottles which may be virtually equal in size. This is because the threads of the prior art would need to be formed to vary according to this wide variety of conventional bottles and caps and threads and the resulting costs for manufacture and distribution required to accommodate this plethora of threaded engagements and bottle types. Further, because a threaded engagement normally takes a bit of time to rotationally engage mating threaded surfaces, users are liable to not employ such devices in the busy confines of a bar or at a lively party.

Furthermore, the threads of Cohn are located on the base of the actual liquid holding portion of the shot glass, which in use is employed as a user drinking vessel. Threading the bottle into the same space occupied by what a user drinks, can expose the contents of the body to the pathogens known to inhabit the human mouth if the device is not washed first which is highly possible. To subsequently replace this cap as a bottle cap is at best unsanitary. In addition, as noted, providing threads as a means for engagement to a bottle requires a bartender to constantly thread and unthread a shot glass as needed, and as noted above, taking longer by doing this task runs the risk of reducing possible earned tips.

As such there is a continuing and unmet need for a measured volume drinking vessel such as a shot glass or similar drinking vessel, which is configured to provide quick, easy, and sanitary removable engagement, with the bottle from which the user intends to measure or drink. Such a device should be configured for easy and quick engagement and disengagement to a wide variety of bottles or bottle caps to allow widespread use. Such a device should be configured to keep germs and pathogens from the user's mouth and face, separated from the contents of the bottle when the device is reattached. Such a device should be easy to mount and dismount from its bottle mounting but still provide a secure mount and in some instances a sealed engagement with the bottle itself.

SUMMARY OF THE INVENTION

The device herein disclosed and described provides a solution to the shortcomings in prior art and achieves the above noted goals through the provision of a measured volume drinking and measuring vessel, shown and described as a shot glass. The shot glass is configured for universal removable engagement over a bottle cap and engaged therewith to the underlying bottle.

In the particularly preferred modes, the disclosed device includes a cylindrical body having a measured fluid vessel portion physically separated from a formed base portion at the opposite end of a centrally located wall. The base portion, so separated, inhibits pathogens from getting into the bottle and has a formed means for removable engagement to a bottle or cap as part of the cylindrical body.

In all modes of the device, the fluid vessel portion typically resembles and is dimensioned as a shot glass as is conventionally known in the art. The base portion generally includes a circular recess defined by a surrounding sidewall and means for engagement for maintaining the device in an engaged position to the top of a bottle cap or the cappable bottle. The biasing of the frictional engagement may be provided by a circumferential protrusion disposed within the circular recess of the base or one or a plurality of similarly disposed compressible but rebounding O-rings, both of which provide a means for snap over fit type engagement. Alternatively, flexible members having projections and/or secondary thread engaging projections provide means for engagement to the bottle or cap.

It is an advantage of this and other modes of the present invention to provide a “snap on” means for quick removable engagement to a bottle or cap in that it provides quick and easy operation to encourage use. Such an engagement requires no rotational thread engagement and separates and rejoins with the force exerted axially by the user's grip of the device.

Additionally, the engagement between the bottle and the device maintains separation from the drinking end of the device and the bottle threads, and as such it does not come into direct contact with the threaded portion of a bottle which can risk contaminating the enclosed liquor with pathogens from surfaces on which such a device sits. Furthermore, in all modes of the device, the original screw on or compressed cap can remain on the liquor bottle as intended by the manufacturer.

In another particularly preferred mode biased frictional engagement between the device and the bottle or cap, can be maintained using a rebound type biasing means such as opposing flexible members, protrusions or O-ring disposed within the circular recess of the base portion which are configured in pitch and projection to optionally provide a means to engage to the threads of a bottle or projections from the exterior of the bottle surface. In this mode, the device is also employable to replace a lost or otherwise unwanted bottle cap.

In yet another particularly preferred mode the device includes a universal bottle cap that is designed for removable engagement with the device. The universal bottle cap simply replaces the existing bottle cap of the liquor bottle and is specifically purposed for removable engagement with the device.

With respect to the above description, before explaining at least one preferred embodiment of the herein disclosed invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangement of the components in the following description or illustrated in the drawings. The invention herein described is capable of other embodiments and of being practiced and carried out in various ways which will be obvious to those skilled in the art. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

As such, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing of other structures, methods and systems for carrying out the several purposes of the present disclosed drinking vessel device. It is important, therefore, that the claims be regarded as including such equivalent construction and methodology insofar as they do not depart from the spirit and scope of the present invention.

As used in the claims to describe the various inventive aspects and embodiments, “comprising” means including, but not limited to, whatever follows the word “comprising”. Thus, use of the term “comprising” indicates that the listed elements are required or mandatory, but that other elements are optional and mayor may not be present. By “consisting of’ is meant including, and limited to, whatever follows the phrase “consisting of”. Thus, the phrase “consisting of” indicates that the listed elements are required or mandatory, and that no other elements may be present. By “consisting essentially of” is meant including any elements listed after the phrase, and limited to other elements that do not interfere with or contribute to the activity or action specified in the disclosure for the listed elements. Thus, the phrase “consisting essentially of” indicates that the listed elements are required or mandatory, but that other elements are optional and mayor may not be present depending upon whether or not they affect the activity or action of the listed elements.

It is an object of the invention to provide a measuring vessel such as a shot glass which is configured in an easily removed engagement to a bottle or cap that is sanitary, easy to use, and cost effective in manufacture.

It is another object of the invention to provide a drinking vessel such as a shot glass with means for removable engagement which employs an axial force engageable and removable snap fit style engagement such as provided by O-rings, opposing flexible members, or similar means for biased frictional engagement with bottle threads or protrusions.

It is yet another object of the invention to provide a means for removable engagement including an O-ring or similar means for imparting biased frictional engagement disposed at a pitch angle for optional operative engagement with a threaded portion of a bottle.

It is still another object of the invention to provide a universal bottle cap that is specially designed for engagement with the shot glass of the present invention.

Yet another object is the provision of a shot class type measuring and drinking vessel, which is adapted for easy engagement over the cap of a bottle, with the exterior of the bottle neck using flexible members which allow for easy axial force directed engagement and securement and which may optionally seal the bottle when so engaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Now referring to drawings in FIGS. 1-18, wherein similar components are identified by like reference numerals, there is seen in FIG. 1 an elevated view of the shot glass device 10 of the present invention. In all favored modes of the device 10 it includes a fluid vessel portion 12 and a base portion 16 which is configured for removable engagement with the cap end of a bottle 25, particularly a liquor bottle 25 for which measurement vessels are employed for mixology.

The fluid vessel portion 12 is defined by a cavity 14 formed by a sidewall extending from a central wall 13 to a lip 15. In a particularly preferred mode the cavity 14 holds 1 to 1.5 ounces of fluid. However, those skilled in the art will appreciate that the device 10 is capable of various size modifications to hold any amount of fluid and is anticipated in this disclosure. The device 10 may be formed of polymeric material or metal or in some cases glass, or material of the like known in the art for formation of measuring vessels such as shot glasses and similar devices. Furthermore, the device 10 can be manufactured using conventional manufacturing techniques known in the art.

FIG. 2 shows a cross sectional view of a mode of the device 10 better depicting a first mode of the base portion 16 which provides a means for removable engagement with a conventional bottle cap 29 (FIG. 14) or bottle 25 neck, via a biased frictional engagement. In all modes the base portion 16 generally includes a circular recessed cavity 18 defined by an interior wall surface 17 of a surrounding sidewall 23. In one particularly preferred mode, the device 10 includes a protrusion 20 annular or in multiple positions around the circumference of the cavity 18, which is formed by a projection of the interior wall surface 17 of the cavity 18 as depicted in FIG. 2. The protrusion 20 is particularly preferred to be formed as a unitary structure with both the base 16 and vessel 12 portion of the device yielding a device 10 formed in a unitary structure.

In use, the device 10 in all modes, may be placed over the top of a capped or uncapped bottle 25 and maintained in an engaged state, using a cooperative removable engagement with the bottle neck or cap 29, within the cavity 18 of the base portion 16. The protrusion 20 provides a means for frictional engagement with the exterior circumference of a bottle cap 29 in a snap fit type engagement where the bottle cap 29 circumference is at least equal to the circumference of the peak of the protrusion 20. Such bottle caps 21 are conventionally aluminum or plastic and will deform to accommodate the frictional engagement of the protrusion 20 surface, which may engage the cap 29 circumference, or just below a lower edge of the cap 29. The device 10 in this mode, provides a quick, convenient, and flashy means to store a shot glass without the need for a threaded engagement which can take a long time to engage due to the multiple rotations required to engage mating threads.

In another particularly preferred mode as shown in FIG. 3 the cavity 18 within the base 16 of the device 10 further includes a first 22 and second 24 annular protrusion disposed on the interior wall surface 17 as a means for biased frictional engagement. This mode provides a means for added securement when engaged to a bottle cap in the as used mode as described. Shown in FIG. 4 is yet another particularly preferred mode of the device 10 in which the cavity 18 of the base portion 16 includes an annular recess 26 on the interior wall surface 17 in which an O-ring 28 is operatively engaged within. This mode further provides a means for removable biased frictional engagement with a bottle cap and may provide a tighter fit to a bottle cap given the compression and rebound flexibility of a typical O-ring 28. Additionally, due to wear that may occur from repetitive use it may be more advantageous to have a replaceable O-ring 28 as opposed to the unitary structure of the mode described in FIGS. 1 and 2.

The O-ring 28 style means for removable engagement is shown in another particularly preferred mode in FIG. 5. This mode employs a first annular cavity 30 and a second annular cavity 32 within the interior wall surface 17 of the base cavity 18. A first 34 and second 36 O-ring 28 are shown as operatively engaged within.

Further particularly preferred modes are shown in FIG. 6 and FIG. 7. There is seen in FIG. 6 an annular cavity 38 within the interior wall surface 17 that is adapted to engage a concave cross section O-ring 40. In use upon engagement with a bottle cap it is preferred that the concave wall of the O-ring 40 engages the exterior of the surface of the bottle cap 29 shown in FIG. 14 for instance. In this manner the concavity can create a suctional engagement providing added security. FIG. 7 shows a first annular cavity 42 and a second annular cavity 44 within the interior surface 17 of the base cavity 18. Similarly employed are a first O-ring 46 and a second O-ring 48.

FIG. 8 shows still further preferred mode of the device 10 wherein the annular cavity 50 and O-ring 52 are disposed at a pitch angle, α 54, relative the horizontal top surface of the bottle. Such pitch angle 54 is provided to employ the device 10 and provide means for a threaded engagement with threads 58 conventionally located atop a screw on capped bottle. In this mode the device 10 doubles as the actual bottle cap. The pitch angle 54 as such corresponds to the pitch angle of the threaded bottle top to provide secure engagement. It must be noted that the provision of a pitch angle 54 may be employed on any of the modes previously disclosed and is not limited to the O-ring style biasing means as depicted in the figure.

There is seen in FIG. 9 another preferred mode of the device 10 having a complimentary bottle cap 11. The bottle cap 11 is of generally the same style and construction of liquor bottle caps known in the art although further including a annular recessed cavity 56 about the outer surface 55. The annular cavity 56 is employed for cooperative engagement with a compressible annular ring such as an O-ring which forms a means for biased engagement within the base cavity 18 of the shot glass device 10 of the present invention. A cross sectional view is shown in FIG. 10 showing the cap 11 having a threaded 58 interior, prior to cooperative engagement within the cavity 18 of the base portion 16 of the device 10. It must again be noted that the bottle cap 11 can be employed with any of the modes previously disclosed upon simple modifications that would be obvious to a person skilled in the art, and should not be considered limiting by the depiction in the figure.

FIG. 11 depicts the device 10 and cap 11 operatively engaged wherein the O-ring 28 is seated within the recess cavity 56 of the cap 11.

A still further mode of the device 10 is shown in FIG. 12. In this mode the means for biased frictional engagement with a bottle cap 29 (FIG. 12) is employed within the cavity 14 of the fluid vessel portion 12. The device 10 in this mode the device provides a means for removable engagement to a liquor bottle 25 wherein the device 10 is inverted and engaged to a bottle cap such as that in FIG. 13 or FIG. 14.

As in FIG. 12 the cavity 14 employs an annular recess 26 on the interior wall surface 19 in which an O-ring 28 is operatively engaged within. It must be noted, however, that the employment of a means for biased frictional engagement within the cavity 14 of the drinking vessel 12 can be any of those particularly preferred means for removable engagement preciously disclosed in FIGS. 2-8 and should not be considered limiting by the depiction.

As shown in FIG. 13 a cooperative bottle cap 11 is in operative engagement with the device 10. However, the device 10 in this mode may similarly be operatively engaged to any existing bottle 25 or bottle cap 29 (FIG. 14) as noted with the previous preferred modes, while the engagement with the preferred bottle cap 11 is shown merely for demonstrative purposes.

It is further noted that the mode of the device 10 shown in FIGS. 12 and 13 may be employed in combination with any of the modes of the device 10 in FIGS. 2-8 wherein a means for removable engagement to a bottle cap is also disposed within the cavity 18 of the base portion 16. In this manner the employment of the device 10 will be user determined, i.e. removable engagement with either the base portion 16 or the vessel portion 12.

FIG. 14 depicts another particularly favored mode of the device 10 herein having a plurality of raised surfaces 61 at distal ends of flexible members 63 formed by voids in the sidewall 23 which impart a biasing force, toward an inserted bottle 25 or cap 29 for an enhanced frictional engagement to the exterior of the bottle 25, or the cap 29 depending on their number and location. As shown, the raised surfaces 61 form a projection at a position configured to provide a means to engage the bottle 25 itself either adjacent to the cap 29 or on the opposite side of an annual stop ring 67 or the exterior threads 58 provided with conventional bottles 25 for such caps. As can be seen the number and position of the raised surfaces 61 may be changed to deflect the flexible members 63 away from the bottle 25 which causes the inward bias and increased frictional or mechanical engagement of the flexible members and raised surfaces 61.

However, the device 10 is still easily engaged by a simple sliding of the cavity 18 axially upon the capped end of the bottle 25 since the flexible members 63 and attached raised surfaces 61 will deflect away from any engagement to the bottle or cap while force is applied in the axial direction of the bottle. Thereafter, the flexible members 63 impart biased force in the direction of the axis of the bottle 25 and upon the contacts between the raised surfaces 61 and their contacts with the exterior of the bottle 25. An increase in the thickness of the raised surfaces 61 provides a means to increase biasing pressure whereas thinning it will decrease biasing pressure if desired.

As shown in FIG. 14, one preferred mode of the device 10 places the raised surfaces 61 in positions to override an annular ring 67 conventionally employed on many liquor bottles 25 during the axial translation which occurs while the user engages the device 10. Thus, the raised surfaces 61 override the annular ring 67 by a flexing of the flexible members 63 during engagement and thereafter provide means for engagement of the device 10 to the bottle 25 which is especially strong. This mode of engagement works well if the device 10 is employed as the cap and if a seal 71 is provided as shown in FIG. 14b, the engagement of the raised surfaces 61 against the side surface of the annular ring 67 is sufficiently strong to hold the seal 71 compressed and sandwiched between the sidewall 23 and the top edge of the bottle 25.

FIG. 14b depicts a particularly favored mode of the device 10 which may employ the engagement capabilities of that of FIG. 14 or 17, but which also may employ two or more slidably engageable projections 80 which will engage with the threads 58 of the bottle 25 and allow the device 10 to function as a sealed cap. Preferably a first surface 81 is angled to form a ramp, whereby the bottle edge 83 and the threads 58 will slide thereon and deflect the flexible members 63 during a forced axial translation of the device 10 by a user sliding upon the end of the bottle 25. Once that force ceases, the projections 80 are positioned to engage within the gaps forming the threads 58. This engagement of the projections 80 within the recesses or gaps of threads or if appropriately positioned, on the opposite side of the projecting annular ring 67 from the cap end of the bottle 25 provides an especially secure engagement which is not easily removed by dropping or bumping. Removal is accomplished by exerting sufficient force in an axial direction away from the bottom of the bottle 25 and toward the cap end, to deflect the flexible members 63, or by rotating the device 10 to allow the projections 80 to follow the threads 58 and unscrew or loosen it from the bottle 25.

The device 10 may employ the projections 80 in place of the raised surfaces 61 to engage either or both of the threads 58 and the annular ring 67. The projections 80 may also be employed with shorter flexible members 63 so as to engage with the threads 58 of the bottle 25. A more universally engageable device is provided by providing flexible members 63 with either the projections 80 at the distal end to engage a ring 67 and positioned to engage the threads 58 or with projections positioned to engage the threads 58 and the raised surfaces 61 positioned to engage a ring 67. In this fashion should the ring 67 not be present, a translatable engagement of the threads 58 is still achievable, and if the ring 67 is present, the projections translatabley engage with the threads 58 and a second engagement is achieved with the side of the ring 67. A seal 71 in any of the modes of the device of FIGS. 14 and 14b enhances its ability in that it may also function as a sealed lid should the cap be lost or need replacing.

FIGS. 15 and 16 show a perspective view of the device 10 and the cavity 18 flexible members 63 defined by gaps 85 formed in the sidewall 23 which is formed of a flexible material such as a polymeric material or thin metal. As noted the flexible members 63 will deflect when axial force in a direction from the cap engageable end of the bottle toward its bottom end is applied by the user with the capped end within the cavity 18. Thus, an easy and fast means for engagement using translational movement is provided which encourages use and helps prevent losing the device. As noted the projections 80 may be used in lieu of the raised surfaces 61 or in combination therewith.

FIG. 17 is a side view of a dismounted mode of the device 10 as described and enlarged to aid in depiction of structure. The flexible members 63 are shown as are the gaps 85 formed in the sidewall 23 defining them. The raised surface 61 is positioned upon the flexible members 63 so as to engage with the annular ring. Of course the configuration of FIG. 14b is also employable substituting or including the projections 80 in place of or in combination with the raised surfaces 61. FIG. 18 is a sectional view of the device of FIG. 17, taken along line 18-18 and showing the components of the device 10.

While all of the fundamental characteristics and features of the invention have been shown and described herein, with reference to particular embodiments thereof, a latitude of modification, various changes and substitutions are intended in the foregoing disclosure and it will be apparent that in some instances, some features of the invention may be employed without a corresponding use of other features without departing from the scope of the invention as set forth. It should also be understood that various substitutions, modifications, and variations may be made by those skilled in the art without departing from the spirit or scope of the invention. Consequently, all such modifications and variations and substitutions are included within the scope of the invention as defined by the following claims.
