referring first to fig2 a container of the invention is shown with a circumferential support bead 20 and a bail 30 . the container 10 includes an outer cylindrical wall 11 terminating at its open end in a rim 15 designed in a known manner to mechanically receive a cover ( not shown ) for the container . referring to fig3 the container also includes a bottom or floor 12 which is integrally formed with the side wall 11 and is disposed slightly above the bottom end of the side wall , creating a bottom rim portion 14 . if so desired , the floor may also include a stiffening circumferential groove 13 , which is spaced a short distance radially inwardly from the bottom rim 14 and protrudes into the interior of the container . this groove may be configured to mate with a similar configuration formed on the upper side of the container &# 39 ; s cover to facilitate stacking of filled containers for storage and shipping . a support bead 20 is disposed slightly below the rim 15 on the outer surface of side wall 11 . the support bead comprises an annular upper wall 23 which is formed integrally with the vertical side wall 11 ( best seen in fig5 ), a circumferentially extending generally vertical outer wall 21 spaced radially outwardly from the side wall 11 , and a structural support lattice 22 disposed in the circumferential cavity formed by the side wall 11 , the upper wall 23 , and the outer wall 21 . the support lattice is preferably comprised of a series of generally x - shaped structural webs extending vertically downwardly from upper wall 23 and terminating substantially even with the lower edge of outer wall 21 . these x - shaped webs are contiguous so that they form a continuous , generally diamond shaped lattice structure as shown in fig3 . the individual webs forming each x desirably intersect at right angles . this lattice structure , which includes triangular elements , greatly enhances the structural rigidity of the container at its upper end and , in combination with the support provided by the floor 12 , provides the container with substantial resistance to deformation and potential overflow of the contents of the container when the container is hung from the bail . the bail 30 is integrally formed with the container . the bail includes a manually graspable central portion 31 , two identical , generally horizontally extending bosses 36 which are formed as extensions of the upper wall 23 of the support bead 21 on opposite sides thereof , and identical flexible hinge portions 33 disposed between the central portion and the bosses . the bail desirably is formed in a horizontal plane ( when the container is viewed as upright ) substantially parallel to the upper wall of the support bead 23 , the bail being generally congruent to the confronting wall 21 of the bead 20 . the central portion 31 of the bail may be of any desired cross - sectional configuration and is shown as having a strap - like configuration that is generally rectangular in cross - section in fig2 - 4 and 6 . preferably , however , the central portion is generally circular in cross - section as shown in fig7 and 8 to present a rounded surface that can comfortably be held in the hand when the container is supported by the bail without having sharp edges of the bail bite into the hand . referring particularly to fig7 and 8 , this central portion is desirably solid in cross - section . as will be evident from these figures , this construction results in the central portion of the bail having a significantly greater cross - sectional thickness than adjacent portions of the container . the bail may , if so desired , also include a central notch for centering it on a hook or other support when the container is in use . the notch is formed on the inner surface of the bail , substantially equidistant from the bosses 36 . the hinge portions 33 formed at the respective ends of the bail have flexible portions 34 which are disposed on diametrically opposite sides of the container , and normally lie in a plane substantially parallel to the support bead &# 39 ; s upper wall 21 when the bail is in a horizontal plane . referring to fig4 each hinge portion 33 includes a transition segment 32 adjacent its flexible portion 34 . this transition segment is preferably solid so that it provides a strong connection between the manually graspable central portion of the bail and the flexible portion 34 ; it may be larger in cross - section than the manually graspable portion of the bail , as shown , or it may be of any appropriate thickness which provides the necessary strength . the flexible portion 34 abuts the transition member 32 and is formed with an arcuate underside 35 which gives the flexible portion a variable thickness which is at its thinnest near the middle of its length . in the preferred embodiment of fig7 and 8 , the cross - sectional configuration of the bail changes from generally rectangular at the location of the hinge portions 33 to generally circular at its central portion 31 , the change in cross - section occurring in the transition segment 32 . as best seen in fig6 when the bail is lifted into an upright position , the thin , flexible portion 34 presents an area of preferred sharp bending , e . g ., about a radius of not greater than about 1 / 4 inches and preferably not greater than about 1 / 16 inches . thus , the bail can be swung through a right angle into a substantially vertical plane . in this position , depicted in fig2 a center line &# 34 ; c &# 34 ; along the axis of the container passes generally vertically through or very near the center of gravity of the container , the center of gravity of the contents of the container , and through the upper part of the bail . each boss 36 may include an area of increased thickness and width at its end that abuts the hinge portion 33 to define a connector 37 providing a strong connection between the rest of the bail and the support bead . as seen in fig3 the end of each boss 36 is wider than the hinge portion so that the boss extends from the outer edge of the bail to the support bead to provide a space between the boss and the support bead , insuring that the boss is freely pivotable upwardly and downwardly about the hinge portions . referring now to fig1 and 2 , the advantage of a hinged integral bail in a container of this invention over conventional bails known in the prior art is readily apparent . prior art containers with integrally formed handles typically have bails of substantially uniform thickness and stiffness . when one suspends a filled container of this type by its bail 50 , as shown in exaggerated form in fig1 the axis &# 34 ; c &# 34 ; of the container does not pass through the bail ; that is , because of the stiffness of the bail , neither the bail nor the axis of the container is vertical . as a result , the upper rim 52 lies in a plane tilted slightly with respect to the horizontal , and this result , coupled with inward movement of the sides of the container at its top as shown by arrows &# 34 ; a &# 34 ; in fig1 may allow a portion of the contents of the container to spill over the edge . in the present invention , the problem is solved by providing the bail with specifically located flexible hinges that enable the bail to be bent sharply upward , and by providing a stiff circumferential bead adjacent the rim that resists deformation . as shown in fig2 the center line &# 34 ; c &# 34 ; of the container passes through or very nearly through the bail when the container is nearly full ; that is , the weight of the container and its contents exert sufficient gravatational force to deform the bail into this position . thus , the upper rim 15 , which is maintained generally circular by the bead 20 , lies in a substantially horizontal plane and the contents of the container are less likely to spill . while a preferred embodiment of the present invention has been described , it should be understood that various changes , adaptations , and modifications may be made therein without departing from the spirit of the invention and the scope of the impended claims .
