2 Figure 2 is a cross-sectional view taken on line 2--2 of Figure 1 showing the floating closure; Figure 3 is a cross-sectional view like Figure 2 but showing how my floating closure operates The floating closure generally indicated as H is comprised of a bottom wall 18 having a frustoconical wall 19 extending outwardly and upwardly therefrom. A cap 80 having an annular downturned edge 81 encompasses the edges of the wall 19 to form a bouyant seal. An upwardly extended dimple 82 (Fig. 4) is formed in the center of the cap 80 of ,theclosure 77. as Figures 2 and 3 show,,a"hollow floating closure 17 is formed which will float nicely on the top of any liquids which may be placed into the carafe when the contents of the carafe are being poured as shown in Figure 3.

At the rear of the closure TI and extending up from the outer annular edge-:Blof the cap 88 is a tongue 83 having anoutwardly extending shoulder 84. When the carafe is in operative position the tongue 83 fitstbetween the lug 76 of the removable cap 13 and the side wall of the cap 13 and between a cut out portion of the wall 10 of the protective jacket 6| as shown in Figure 1. The? shoulder 84', of the tongue 83 retains the tongue between these .elements and also acts as a pivot when" the buoyant. closure is floated when the contents ,of thecarafe are being poured.

{Iw-orsmall,orifices lliwhich extend into a circular channel 86 partially cut out from the wall 70- of-the jacket BI and the wall of the remov able cap l3 permits airgcommunication to equal- 9 air p s ures between the atmosphere and the-:inside-of the carafevvhen the carafe is being poured. It is to be noted that the channel 86 finds an opening into the interior of the carafe through the cutout portion of the wall ill of the protective jacket 6| where the tongue 88 of the floating closure 17 is inserted. It has-been found that these air vorifices85 eliminate gurglinginoises which might otherwise be present and also providesa freeuand easy flow of the contents from the carafe.

The carafe-is operated in the following manner. The cap 13 is removed from the jacket 6!. The floating closure 11 is then also removed from off the edge;:65 'of the flan efi l of the jacket 6!. The container :60 is then .fllled with the desired contents and the closure is then seated upon the edge=85 of the flange 64 of the jacket 6!. The cap 73 is then threaded back onto the jacket 81. When a portion of the contents of the carafe is desired the handlet'l is grasped and the carafe appropriately tilted. Thecontents will force the buoyantclosure 71 out so that the closure '17 will float on top of the contents while the contents are being evacuated through the spout 69 as shown in Figure 3. During pouring the recess 15 of the cap 73:;receives-the dimple 32 of the closure 11.

After-the desired amount of the contents are removed, the carafe is then placed upright on its bottom. The closure 71 then resumes its seated position by means ofgravity. .The tongue 83 andxshoulder :84"help.insure that the closure-17 seats properly upon the edge (i of the flange 64 as described.

Thus it is seen-thatthe user of the carafe merely has'to' tilt' the carafe to obtain access to its contents and'no" other digital manipulation is required'as do carafes not employing my invention. Furthermore, since the closure l1 is completely encased within the jacket 6| and the cap 13 and is not exposed to external elements, a more sanitary carafe is obviously had.

While. I have shown and described preferred forms of my invention it will, of course, be understood that it is not limited thereto and that by the appended claims it is intended to cover all modifications aan'd alternative constructions as fall within the true spirit and scope of my invention.
