       BACKGROUND OF THE INVENTION 
       [0002]    The current invention relates to crown-cap openers. 
         [0003]    is Flat Bar openers for crown-cap removers are well known and very old in the art. The most basic form is a generally rectangular strip of metal with rounded ends and one end defining an aperture adaptive to removing crown-caps. An opposite end aperture is often added. 
         [0004]    A problem of the prevalent round end rectilinear shape of openers is that when stored in a pocket of the users clothing the bar will tend to slide to the bottom of the pocket and often turn across the bottom of the pocket inhibiting the quick removal of the opener. 
         [0005]    Observation of bar operations quickly reveals that the users of the openers often utilize them in the manner of a “worry stone” tending to twirl the flat bar around their index finger via an opposite end aperture most often circular and opposite the crown-cap opener aperture. This activity would also appear to be bartender shtick expected by patrons. However, when the user simply clasps the bar with the index finger still inserted, the opener aperture would extend from their hand opposite their thumb which is not conducive to fitting on a cap or its removal. 
       BRIEF SUMMARY OF THE INVENTION 
       [0006]    The current invention provides a side exit channel defined by the opener body between the end apertures which forms a hook shape to be hung on a clothing loop or pocket lip. Another embodiment provides a side extended region which forms a hook for the same purpose. The closed semicircular end of the hook provides a means to twirl the opener about a finger and when clasped the opener will be at the thumb side of the user&#39;s hand and immediately useful to remove crown caps. Both of these embodiments may be practiced with one or more secondary tools defined on the bar body or a primary tool entirely different than the crown-cap opener on the proximal end. These secondary tools being companionate to fit objects including but, not limited to: a hex shape bolt, nut or valve stem; round shaft valve stem with formed opposite flat sides etc. The secondary tools may be of regular or irregular shapes. In defining the shape of an aperture or perimeter of a raised area to be used as a tool the term “regular shape” is intended to be those having commonly geometrically described and perhaps repetitive including but, not limited to, square, rectangular, multisided, splined and those shapes modified with a curved section or internal or external notches or tabs. The term “irregular shape” is utilized as those shapes that although may be descried mathematically are not completely repetitive in pattern. Those tools may be defined and further include defining a channel from the aperture shape through the distal end of the bar creating an open throat as an open end wrench or line wrench as known in the mechanical arts. The outer perimeter of the flat bar may also define yet another tool which requires a blade shape scraper, flat screwdriver or pry bar. 
         [0007]    As best perceived from  FIG. 1  the first embodiment presents a side hook described by the body of the opener. And best perceived from  FIG. 2  the second embodiment the opener has a hook extended from one edge. The closed end of the hook would most often be semicircular but is not limited to that shape. It may be angular including but not limited to, three sides of a hex, forming a tool which may include a portion of the length of the hook and edge of the bar and still twirled about a finger. Chiefly it must be of a shape that will not tend to snag or cut skin, no sharp points or edges. This design would be conducive to making the aperture or outer perimeter opposite the cap opener into a specific tool including but, not limited to, a smaller complete hex or other shape aperture or the outer perimeter forming a wedge shaped pry bar. The objective of this invention is to accomplish at least one of the following: to provide a convenient means to hang the flat bar on the opening of a clothing feature of the user and provide an alternate finger interface conducive to using the bar by the user simply closing their hand to grip and to make more conducive to make the bar end opposite the crown-cap opener into another tool shape.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0014]    Referring to  FIG. 1 , a first embodiment of the crown cap opener  1  is shown in perspective view having bar body  2  being a generally flat rectangular portion with proximal end  3 , cap aperture  5 , distal end  4 , and distal aperture  6 . Many variations of cap aperture  5  are old and well known in the art. Bar body  2  further defines an open end channel  7  exiting on edge  8  having semicircular closed end  9  wherein the region between the channel and the edge  8  of bar body  2  forms hook finger  10 . The user slides the bar body  2  inside a loop or pocket on their clothing leaving hook finger  10  outside the loop or pocket in order to maintain the crown cap opener in a readily accessible position. 
         [0015]    Referring to  FIG. 2 , a second embodiment of the crown cap opener  2  is shown in perspective view. Having the elements of  FIG. 1. 2  through  6  excluding the elements  7  through  10  but further including the inventive side hook  12  extending from an edge near proximal end  3  having hook closed end  13  being semicircular. Closed end  13  may also have an angular profile and in combination with hook inner edge  14  and bar body edge  15  forming  4  of the  6  sides of a hex. Closed end  13  and its adjacent edges should not be keen nor have burrs that would tend to snag or cut human skin. Again, The user slides the bar body  2  inside a loop or pocket on their clothing leaving side hook  12  outside the loop or pocket in order to maintain the crown cap opener in a readily accessible position. The user may also hang the opener on a finger by resting closed end  13  and may twirl the opener about the finger. 
         [0016]    Referring to  FIG. 3 , a third embodiment of the crown cap opener is shown in perspective view having the elements of the second embodiment of  FIG. 2  plus the inventive distal outer tool  17 . Outer tool  17  has a mostly rectilinear profile which may be used as a blade screwdriver, scraper, pry bar or to break packaging. 
         [0017]    Referring to  FIG. 4 , a fourth embodiment of the crown cap opener is shown in perspective view having the elements of the second embodiment of  FIG. 2  plus the profile of distal aperture  6  now being the inventive distal hex aperture  19  being companionate to an outer hex profile object which the user desires to apply torque in the manner of a closed end wrench to a nut, bolt, fitting or valve. Although named as a specific geometric shape, hex, the aperture may be of other non-circular shapes. Also shown is inventive third tool aperture  20  shown as a round end rectangular slot which may be used to operate a valve stem having opposing flat surfaces for operating. Likewise, third tool aperture  20  may be of another non circular profile companionate to the outer profile of an object which the user desires to apply torque. 
         [0018]    Referring to  FIG. 5 , a fifth embodiment of the crown cap opener is shown in perspective view having the elements of the second embodiment of  FIG. 2  plus the inventive distal open tool  23 . As shown distal tool  23  has the profile of a line wrench as known in the mechanical arts which engages all  6  surfaces of a hex but having an distal channel  24  open to pass over a fluid line or stem. The opening of the distal open tool  23  may be expanded and the hex profile rotated to the shape of an open ended wrench also known in the mechanical arts. Again the profile of distal open tool  23  may be of other noncircular profiles. Inventive intermediate aperture  22  is shown having a circular profile. Again, the intermediate aperture  22  may be of a noncircular profile as intermediate third tool aperture  20  companionate to the outer profile of an object which the user desires to apply torque. 
         [0019]    Referring to  FIG. 6 , a sixth embodiment of the crown cap opener is shown in perspective view having the elements of the second embodiment of  FIG. 2  plus the inventive distal raised tool  26  whose profile is companionate to an internal profile of an object which the user desires to apply torque. Again, although shown as a specific geometric shape, hex, the raised tool may be of other non-circular shapes. Also shown is inventive raised tool aperture  27  shown as a round end rectangular slot which may be used to operate a valve stem having opposing flat surfaces for operating. Once again, the raised tool aperture  27  may be of another non circular profile companionate to the outer profile of an object which the user desires to apply torque or a profile to accommodate passing the raised tool over a stem and further may have an open end as  24  of  FIG. 5 .
