Description:
[0001]     This is a regular patent application based on U.S. Provisional Patent Application No. 60/521,527 filed on May 13, 2004. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     The present invention relates to carafes and other types of hand-held beverage dispensers for use in the home, on picnics, at restaurants, etc.  
         [0003]     Prior art beverage dispensers come in various designs and are called such terms as pitchers or carafes. For example, a carafe can be made with an insulating means such as a vacuum liner made of double glass or of some other material. Use of insulating material is a primary reason why carafes are popular for dispensing both hot and cold beverages.  
         [0004]     Many individuals attempt to identify the contents within a beverage dispenser, particularly ones not having a see-through body, by either affixing printed labels to the outside surface of the dispenser body or by applying a piece of masking tape to said outside surface and writing the name of the beverage. These identifying attempts are first, not very aesthetic, and secondly, require to be changed at least as often as when the dispenser is used for different beverages.  
       BRIEF SUMMARY OF THE INVENTION  
       [0005]     The invention pertains to a cap or cover which can be made for use on any hand-held liquid beverage dispenser. The cap can be designed to be aesthetically pleasing, easily cleaned and functional. For descriptive purposes, the cap is presented along with a carafe-type beverage dispenser having a hollow body and a neck portion for containing liquids and a cap for engaging the inner wall of the neck portion.  
         [0006]     Depending upon the type of beverage dispenser, the cap portion can be manufactured to include a threaded base adapted for engagement with the female threads located at the neck of a typical carafe base.  
         [0007]     As another example, rather than having a threaded base, the cover can be manufactured with a thumb trigger so that contents can be poured from the dispenser only after the trigger is pressed, displacing the cover away from the dispenser opening in a hinge-like manner.  
         [0008]     The novel feature of the cap is a rotatable top portion. Specifically, the cap comprises a base, a rotatable top portion having an aperture or window, and multiple indicia disposed about the top surface of the base between the base and top portion.  
         [0009]     The indicia can be disposed upon the top surface by any of the well known methods in the art such as stamping, silk screening, adhesive or lamination.  
         [0010]     The indicia is arranged in a circular pattern. Along different portions of the circumference on the nameplate can be written various designations such as: “Coffee”, “Tea”, “Decaf”, “Water”, “Lemonade”, etc.  
         [0011]     The aperture or window is sized so that only a limited portion of the base top surface is viewable and that only one indicia is viewable at a time. The aperture can be configured to have a see-through plastic layer or it can be simply an open area.  
         [0012]     The rotatable top portion can be incrementally rotated until the desired beverage designation appears through the aperture. Preferably, the cap is designed so that a slight frictional resistance maintains the desired position of the aperture relative to the indicia. Designing the cap with a slight frictional resistance is well known in the art and will not be discussed in detail herein.  
         [0013]     In this way, a dispenser body can be filled with a beverage and the base portion of the cap or cover is positioned in the top opening such as for example, the neck of the carafe body. However, the top portion of the cover can be rotated until the beverage designation appears through the aperture. Rotation of the top portion of the cover does not change the base portion&#39;s position relative to the dispenser body.  
         [0014]     By having a cap which can display through its window a designation referencing the contents within the beverage dispenser, individuals then do not have to guess as to what beverage is inside. This can be particularly beneficial at restaurants, picnics or other large gatherings where multiple dispensers are used each containing a different beverage. 
     
    
     BRIEF DESCRIPTION OF THE DRAWINGS  
       [0015]      FIG. 1  is a perspective view of a beverage dispenser, namely a carafe body and cap.  
         [0016]      FIG. 2  is a top view of the cap.  
         [0017]      FIG. 3  is a view of the cap taken along line  3 - 3  of  FIG. 2 .  
     
    
     DETAILED DESCRIPTION OF THE INVENTION  
       [0018]      FIG. 1  illustrates beverage dispenser  10  as a carafe comprising hollow body  12  and cap  14 . Cap  14  is capable of being threadably engaged to the neck portion  16  of body  12  by threads  18 .  
         [0019]     Cap  14  comprises a base  20  and top  22  which is rotatable relative to base  20 . Base  20  consists of a lower portion having threads  18  and an upper portion. The lower and upper portions are made separately and then bonded together to form base  20 .  
         [0020]     Referring to  FIG. 3 , top  22  has a stem  24  which extends past an aperture in base  20  and has a tapered headed end  26 . Initially, headed end  26  is forced through the aperture and this then prevented from being removed by the taper shape although top  22  is now able to be move about the axis created by stem  24  in its fixed relation to base  20 .  
         [0021]     Top  22  has an aperture A which is covered by see-through plastic. On the top surface of base  20  is disposed a plurality of indicia  28 . Each indicia is a different designation and as illustrated in  FIG. 3 , the indicia viewable through aperture A is “water”. The other indicia  28  identified by hidden lines can be used to describe other beverages such as “coffee”, “decafe”, “hot water”, etc.  
         [0022]     As can best be seen in  FIG. 2 , for each indicia  28  present on the top surface of base  20 , there is a corresponding indentation or aperture B. Head  30  is located on the bottom side of top  22 , facing the top surface of base  20  and is positioned for contact with any of indentations B.  
         [0023]     With the parts of carafe  10  now identified, the carafe is used as follows.  
         [0024]     A beverage is selected and poured into hollow body  12 . The base  20  of cap  14  is rotated so that threads  18  threadably engage neck portion  16 . With cap  14  attached to base  20 , top  22  is rotated until the desired indicia that designates the beverage contained by carafe  10  is viewable through aperture A. When an indicia is fully viewable through aperture A, head  30  partially extends into indentation B, fixing the position of top  22  relative to base  20 . A minor amount of rotating force is required to dislodge head  30  from its position with indentation B, thus allowing top  22  to rotate when desired. Although specific embodiments of the invention have been described in detail, the invention is not limited to the illustrated embodiments and various modifications and variations can be made in the display cap without departing from the spirit or scope of the invention. For example, while the figures show a top portion  22  that is rotatable relative to a base  20  where indicia  28  are provided, an alternative design may include a non-rotatable top portion and a rotatable member disposed beneath the top portion, with a window provided on the top portion and indicia provided on the rotatable member. As another alternative to the window in the illustrated embodiment, the indicia on the base  20  are present at locations exposed by the top portion, and the rotatable top portion has a marking (an indicator) that can be lined up with desired indicia by rotating the top portion. As yet another alternative, indicia are provided on the rotatable top portion, and a marking is provided on an exposed portion of the base so that desired indicia can be lined up with the marking by rotating the top portion. Other alternative designs may be possible. In summary, the invention is a cap with a first member and a second member that is rotatable relative to the first member, with a plurality of indicia provided on one of the first and second members and an indicator (such as a window, a marking, or other suitable indicators that can indicate the desired indicia when aligned with it) provided on the other one of the first and second members.
