(Cl-563 1 3? th s: inv'entidn relates to" improvements in" i l Y It is the object of the invention to provide} a tumbler from which the contents will not spill, regardless of accidents to which it may be subjected in use. Myimprwo' mnbier is designed particularly for use by. children or invalids, or in cli'nirIg'rars oYoffairpla'riswlifi ect to jiggling or tipping. It is my' H I a tumbler froniwl' iicl i' t lie entire-cements may readily be consumed by a normal drinklng operation but from which no loss of-contents will occur if the tu r'fnbler is tipped on to a table surface,- so long as the tumbler isnot inver ted. v
It ismy further object to provide a-tumbler having drinking compart'men-t and a storage compartment and to deliver automatically-subice? to the control of an air look, any amount of liquid; from the storage compartment to the drinking compartment to replace What-hasbeen consumed from the latter; the drinking compartment having an annular channelsufficientlyflarge to hold,'when the tumbler isrlying on 1 'id'e, th entire contents normallyinthe drinkinge cairnpal rtnient:
It is a further object of the invention to provide an attachment auapruws connected with any screw rep jar to conver'fitfie jar into a ensuing wearer embodying the invention? In the drawings:
Fig. 1 is a side elevation of a complete device embodying the invention.
Fig. 2 is a vertical section through the device of Fig. 1.
Fig. 3 is a plan view of the device shown in Fig. 1.
Fig. 4 is a view taken in horizontal section on the line 4-4 of Fig. 2.
Fig. 5 is a fragmentary detail view in transverse section on the line 5-5 of Fig. 3.
Like parts are identified by the same reference characters throughout the several views.
The storage part of the tumbler may comprise a jar 6 having a screw thread I about its mouth. To this, I screw an attachment comprising the appliance 8 having a web portion 9 which almost closes the mouth of the jar and a depending skirt portion III provided with screw threads complementary to those of the jar. The appliance 8 is preferably elliptical in cross section, as best shown in Fig. 3. and elongated or outwardly extended at I I and I2 to the extent indicated by comparison of Fig. 2 with Fig. 3. Thus if the tumbler is tipped over onto its side, it will tend to roll to a posi- I semis-1y.

Amonn'c'e at I8 liquid from thejar to tne'drmk'i'rigcnamber; The duct I'9" leads from a point" near the aperture I8' inwardly through thef web! and diametrically. across the jarto a piii'nfinear itsf ofppds'iteniargiri. Theduct I'9 r'ire'fdeny fipand's" in cross" section as it leads inwardly. Duct I9 serves to admit air to thejar 3 except "lien" its inlet" end 20' is locked against admission bit'h'e accumulation of liquid in tlie cliar'infl at I'T. I
WHen tl'ie operat'or lifts the tumbler, todrink tnrrrem', thedrinkir'ig" chamber above the hori zontal partition: Will-be empty,--its entirecontents Having drained back through the port I8 into the jar. As the user tilts the tumbler to drink therefrom, the contents of the jar 6 will flow through the orifice I8 into the drinking chamber until the liquid accumulates in channel I I to a depth suflicient to cover orifice 20, whereupon the duct I9 will be sealed and no appreciable additional quantity of liquid will flow from the jar into the drinking chamber until sufficient liquid is drunk from the chamber to expose orifice 20 to admission of additional air. As rapidly as the user consumes the liquid from the drinking chamber, additional liquid will be supplied from the jar.
Assuming the device to be dropped or assuming that it is tipped over while liquid still remains in the drinking chamber above the partition 9, the greater radial projection of the appliance at I2 will tend to prevent the device from lodging in a position in which the orifice I8 is downward. The
shape of the appliance will tend to cause the jar to roll to a position where the appliance has a. minimum radial projection. In any such position, the channel I! will have sufiicient capacity to hold the liquid contents of the drinking chamber. It is not essential that the appliance have extra radial projection at H. Nor, in fact, is it necessary that the appliance necessarily have any abnormal radial projection at any particular point. However, the preferred location of the inlet 20 to the air bleed duct I9 is preferably somewhat removed inwardly from the orifice l8 and, to prevent overflow in the event that the jar falls with the orifice I8 downwardly, it is preferred that the appliance be enlarged at [2 to cause the jar to roll from the position in which such leakage may occur.
1. A cup-like extension for a drinking recep tacle having a bottom for capping the receptacle said bottom being provided with a restricted aperture near one margin through which liquid may be slowly poured from the receptacle, said bottom also being obliquely perforated to form a vent leading from its upper surface near said aperture downwardly and across the bottom to a point in its under surface near its opposite side, and said extension having side walls inturned at their upper margins to retain liquid escaping through the aperture when the receptacle and its extension is tilted at right angles to the'normal upright position, and said side walls having portions arcuately extended horizontally.
2. A closure for the circular mouth of a receptacle, said closure comprising a cap adapted to span the receptacle mouth and provided with a receptacle engaging flange interiorly of circular contour, the cap further being provided with bores opening to the upper face of the cap closely adjacent each other at one side of the cap, one of said bores extending directly through the cap and the other extending obliquely to open below the cap at the opposite side thereof, an upstanding wall about the cap having an inwardly overhanging rim cooperating with the cap and said wall to define a channel, and a drinking lip upstanding on a portion of said rim above that side of the cap at which said bores open to the upper face thereof.
3. The device of claim 2 in which said cap is provided with an external radial projection from the last mentioned side of the cap to prevent said side from lodging downwardly in the event of the upsetting of a receptacle to which such cap is applied.
4. The device of claim 2 in which the cap is -a point near the aperture at the top surface of the wall to a point remote from the aperture at "the lower surface of the wall, and an annular rim rising above said wall and providing a drinking chamber and having an inwardly overhanging flange portion forming a channel having suflicient capacity to hold the contents normally in said cap, the said vent tending to limit the said contents when the cap and receptacle are tilted for drinking by becoming sealed when the liquid in the cap covers the vent at the point first mentioned.
