Claims
What I now claim is:
1. In a non-spill cup, the combination of a cup vessel and a
closure cover, said cover having self-contained means to permit a
person to drink the contents of said cup vessel, and also having
self-contained means to prevent the liquid content within said cup
to be spilled when said cup is accidentally dropped and struck
against a floor or ground, said cup comprising a container
including a bottom wall and side wall, the upper end of said side
wall having an internal thread for engagement with an external
thread of said cover removably secured thereto, said cover being
provided with an upwardly extending spout with a central opening
therethrough, said cover additionally including an air return vent
extending therethrough, said spout opening being of larger capacity
cross section than said air return vent, said cover including a
closure mechanism for closing the inner ends of said spout and said
air vent, said closure mechanism comprising a central plunger
extending through said cover, the upper end of said plunger having
a knob secured thereto, a compression coil spring around said
plunger located between the lower end of said knob and the upper
side of said cover, the lower end of said plunger being integral
with a closure member which at its opposite ends is provided with a
seat into which a lower end of said spout and said air vent are
receivable so to seal off the lower ends of said spout and said air
vent, said spout opening having a wide outlet, and said air vent
having a plurality of individual outlets.
Description
This invention relates generally to drinking vessels.
A principal object of the present invention is to provide a
drinking vessel which permits a person to drink directly therefrom
but which includes self-contained means whereby the liquid content
from within the cup will not spill out in case the cup falls upon a
floor or the ground.
Another object of the present invention is to provide a non-spill
cup wherein the interior thereof is normally sealed but which can
be made for a person to drink directly therefrom when the person
depresses a plunger for releasing an interior closure from the
inner end of a drinking spout formed on a cover of the cup.
A further object of the present invention is to provide a non-spill
cup wherein the plunger and closure additionally seal the inner end
of an air vent provided on the cup cover and which is normally used
for air entering the interior of the cup so to displace the liquid
being dispensed therefrom.
Other objects of the present invention are to provide a non-spill
cup which is siple in design, inexpensive to manufacture, rugged in
construction, easy to use and efficient in operation.
These and other objects will be readily evident upon a study of the
following specification and the accompanying drawing wherein:
FIG. 1 is a top plan view of the present invention, and
FIG. 2 is a side elevation view thereof shown partly in cross
section.
Referring now to the drawing in detail, the reference numeral 10
represents a non-spill cup according to the present invention
wherein a cup vessel 11 which is normally closed by means of a top
cover 12.
The cup 11 includes a bottom wall 13 and a cylindrical or conical
side wall 14 which at the upper end thereof is provided with an
internal thread 15 for engagement with an external thread 16 around
the cap or cover 12.
The peripheral edge 17 of the cover is provided with an annular
groove 18 within which there is fitted a rubber ring 19 and which
serve as a shock absorber in case the cup is dropped and strikes
there against when landing upon a floor or other surface.
The cover includes an upwardly extending spout 20 having a central
opening 21 therethrough which at its lower end is circular in
cross-section but which at its upper end is slot configurated as
shown at 22 so to be conveniently placed between a person's lips
when drinking therefrom.
Additionally the cover 12 is provided with an air return vent 23
which permits air to enter the interior chamber 24 of the cup
during a drinking action so to replace a liquid being poured
outwardly therefrom .
A mechanism 25 normally seals the inner ends of the spout opening
and the air return vent opening so that when the cup is tipped over
no liquid will be accidently dispensed therefrom.
The mechanism 25 includes a central plunger 26 extending through
the cover 12, the upper end of the plunger being provided with a
dished knob or button 27 against which a person may place his
finger 28 for depressing the same.
As shown in FIG. 2, a rubber gasket 32 is fitted all around between
the cup 11 and the top cover 12.
A compression coil spring 29 is fitted around the plunger and
located between the knob and the upper end of the cover 12. The
lower end of the plunger is secured fixedly to a closure or flat
piece 30 which at opposite ends is provided with a pocket or seat
31 within which the lower ends of the spout and the air vent are
receivable so to normally seal these off.
In operative use, in order to drink the contents within the cup, a
person simply tilts the cup over by placing the spout 20 between
his lips. He then depresses the plunger 26 by placing his finger 28
against the knob 27 and pushing the same inwardly so as to cause
the closure to move away from the inner ends of the spout and air
vent openings, thus permitting the liquid to be moved outwardly of
the cup and the space within the cup being replaced by air moving
inwardly through the air vent 23.
In case the cup is accidently dropped, the compression spring 29
retains the closure in a sealed position against the inner end of
the spout and air vent openings thereby preventing loss of the
liquid.
