Description




BACKGROUND OF THE INVENTION




The present invention relates generally to sanitary shields and more particularly to universal sanitary shields for media dispensers. Still more specifically, the present invention relates to sanitary shields which prevent contamination of dispenser terminals and media or products they dispense, by preventing direct contact between the dispenser terminals and the dispenser users or other foreign matter.




Many types of dispensers are known to the art for dispensing media or products. Such dispensers are known for use, for example, in the medical field, for industrial products such as dry chemicals and for various food products, such as ice cream, desert toppings, nuts, coffee, candy, soft drinks, water and the like. However these dispensers do not provide protection from contamination for the media or products being dispensed from contamination. Contamination of the dispenser terminals and the media or products they dispense may easily occur when contact is made with the user or foreign matter because the dispenser terminals are exposed. For example, children have been observed touching terminals of soda dispensers, water coolers and ice cream dispensers when they may have germs on their hands. Also people have been observed coughing or sneezing in close proximity to dispenser terminals. It is, therefore, highly desirable to provide a sanitary shield to prevent such contamination.




SUMMARY OF THE INVENTION




It is a primary object of the present invention to provide a universal sanitary shield for media or product dispensers to protect the dispensing media or products and the dispenser terminals from contamination.




Another object of the present invention is to provide a device that effectively shields dispenser terminals and dispensing media or products from contact by users or other foreign matter.




Another object of the present invention is to provide a universal sanitary shield that is economical to manufacture and which may be readily manufactured, and easily be put on and taken off of a dispenser for replacement or cleaning by unskilled workers.




Another object of the present invention is to provide a device that may comprise a single component which may be made entirely of a single material such as a polycarbonate or other clear plastic material that can afford a good view of the product or media being dispensed.




Briefly, the present invention is directed, in its preferred embodiment, to a universal sanitary shield which effectively protects the terminals of dispensers and media, or products they dispense, from becoming contaminated from contact with users or with foreign objects such as air-born germs when someone sneezes or coughs. The sanitary shield is preferably a single component and preferably comprises a generally cylindrical shape somewhat larger in diameter and longer in length than the dispenser terminal and having open ends. It is preferably constructed of a clear plastic resin such as polycarbonate, but may be of glass, metal or other suitable material. One end of the shield is designed to snap, twist or otherwise be engageably attachable to a dispenser or dispenser terminal in such a way as to position the shield to effectively protect the dispenser terminal. The other end of the shield preferably terminates slightly beyond the end of the dispenser terminal. Thus, the universal sanitary shield prevents a user from contaminating the terminal by touching it and prevents contamination by shielding the terminal from a user sneezing or coughing on it.




Although four embodiments are illustrated, it will be understood that the device can be manufactured in a variety of shapes and sizes to accommodate a wide variety of dispensers or dispenser terminals. It will become clear that the present invention provides a unique and desirable device for dispensers by creating a sanitary shield for protecting dispenser terminals and dispensing media or products from contamination.

DESCRIPTION OF PREFERRED EMBODIMENTS




Turning now to a more detailed consideration of the present invention, there is illustrated in

FIG. 1

a perspective view of a universal sanitary shield


10


, for a typical media or product dispenser. The shield


10


includes a cylindrical body


20


with an open top


30


, and an open bottom


40


for providing contamination protection for media or product being dispensed from a dispenser, generally L-shaped and a locking slot


50


in the body


20


extending downwardly from a top edge


60


of the body, for attaching and securing the shield


10


to a typical dispenser or dispenser terminal.




The body


20


preferably is a single component which comprises a generally cylindrical form, length and diameter to conform to a typical dispenser or dispenser terminal. It is preferably constructed of a clear plastic resin, such as a polycarbonate, for providing a clear view of media or product being dispensed, with the wall of the body


20


being sufficiently thick to provide the desired stiffness and strength to allow it to be secured on a dispenser.




In

FIG. 2

, the function of the sanitary shield


10


will become clear when taken in conjunction with a typical dispenser, indicated at


100


. The dispenser


100


, which is shown for illustrative purposes, includes a dispenser terminal


110


with an open end


120


for dispensing a media such as soft drinks, water, ice cream, nuts, coffee, candy, desert toppings, diy chemicals, medicine, pills or the like. It also includes a pen or locking-knob


130


for engaging the slot


50


and securing the sanitary shield


10


.




The shield


10


is slightly larger in diameter and somewhat longer than the dispenser terminal


110


. An unskilled worker can readily attach the shield


10


to the dispenser


100


by sliding the shield upwardly so that the locking-knob


130


on the dispenser terminal


110


engages the locking-slot


50


of shield


10


. Thus the shield


10


is attached simply by pushing it on and turning it to secure it in place. This embodiment may be desirable, for example, if the dispenser terminal


110


is a quick connect or detachable component of the dispenser


100


. Alternatively, the shield


10


may be attached directly to the body of the dispenser


100


by various other connectors. For example, the attachment of the shield


10


to the dispenser


100


or to the dispenser terminal


110


may be in any manner as is known in the industry, such as snap-on, lock-on, screw-on or the like.




A second embodiment of the invention is illustrated in

FIGS. 3 & 4

. The sanitary shield


10


is similar to that of

FIGS. 1 & 2

, the difference being that a lower portion, indicated at


45


, is larger in diameter than an upper portion, indicated at


25


, of the body


20


and the locking-slot


50


(

FIG. 1

) has been replaced by an expansion-space or slot


60


. The expansion-space


60


extends the full length of the shield, and allows the shield


10


to expand when pushing it onto the dispenser terminal


110


. The material of the shield is flexible and tends to return the expansion space


60


to its original size, so that the upper portion


25


of the shield


10


contracts to engage the outer surface of the dispenser terminal to hold the shield


10


in place. This embodiment may be desirable, for example, if the dispenser terminal


110


has a constant diameter, such as typical tubing or the like. If so desired the expansion space


60


may extend only partially along the length of the shield


10


.




In operation, the universal sanitary shield


10


of

FIGS. 1-4

creates a sanitary barrier between a typical dispenser terminal


110


and potential contamination, such as from a person sneezing or coughing in close proximity of the dispenser terminal


110


or from a child touching the terminal


110


. Therefore, the sanitary shield


10


provides protection from germs and other contamination for the dispenser terminal


110


and for any media or product it may be dispensing.





FIG. 5

illustrates an alternative embodiment of the universal sanitary shield


10


of the present invention. This embodiment may, for example, be desirable for a typical bottle for dispensing pills, as indicated at


122


. The dispenser


122


includes a dispenser terminal


124


having an open end


126


for dispensing media or product such as pills. The bottle


122


includes an integral shield


130


, having a circumferential wall, or body portion


140


with an open end


150


which is slightly larger in diameter and longer than the dispenser terminal


124


. The dispenser


122


may, if so desired, be a typical medicine or pill bottle in outside appearance, the difference being that it incorporates the inner dispenser terminal


124


and the outer shield


130


. The body


140


of shield


130


may have typical threads on its outer surface, at


160


for attaching a cap or lid (not shown) in known manner, or if desired the cap can be attached to the dispenser terminal


124


to cover opening


126


.





FIGS. 6 & 7

illustrate a combination, indicated at


300


, of a sanitary dispenser shield


310


surrounding a dispenser terminal


320


and comprising a single component. It is preferably constructed of a clear plastic resin, such as a polycarbonate, and may be generally cylindrical in form.

FIG. 6

is a perspective view and

FIG. 7

is a cross-sectional view, taken along line A—A of FIG.


6


.




The combination


300


includes a common top rim


340


and a common open top


350


shared by the shield


310


and the terminal


320


. An open bottom end


360


of shield


310


is separate from an open bottom end


370


of the terminal


320


. As in the other described embodiments, the length of the shield


310


is somewhat longer than the length of the terminal


320


to provide a sanitary barrier around and beyond the end


370


of the terminal


320


. At the uppermost region of combination


300


, the shield


310


and terminal


320


share a common portion


410


. At a pre-determined distance below the top rim


340


, the shield


310


and terminal


320


separate at a junction


380


. The combination


300


also includes an expansion joint


390


, similar to the expansion-space


60


of

FIGS. 3 & 4

. It further includes a typical inwardly extending snap protrusion


400


near its top inner circumference.




As best illustrated in

FIG. 7

, the shield


310


may have the same diameter for its entire longitudinal length from top to bottom. However, if desired, its bottom diameter may be somewhat larger than the top. The portion of the terminal


320


that separates from the shield


310


at the bottom of the common portion


410


, at junction


380


, is preferably conical in form, tapering inwardly with its bottom open end


370


being somewhat smaller in diameter than its common open top


350


diameter.




The fourth embodiment may, for example, replace a typical snap-on dispenser terminal with the combination


300


providing a terminal


320


and a sanitary shield


310


, for a container or other dispenser. The snap protrusion


400


and the expansion joint


390


allow an unskilled worker to readily attach the combination


300


to a typical dispenser (not shown) that utilized a snap on dispenser terminal.




In operation, the very desirable function of the combination


300


is the same as the other described embodiments.




Thus it will be seen that the universal sanitary shields for media dispensers of the present invention is unique. It provides a barrier between a typical dispenser terminal and potential contamination, such as a person sneezing or coughing in close proximity of the dispenser terminal. It is a highly desirable device that provides protection from germs and other contaminants for a dispenser terminal and any media or product being dispensed.




Although the invention has been described in terms of preferred embodiments, it will be understood that these are exemplary and that the scope of the invention is limited only by the following claims.
