12 Claims. (61. 222-147)
The present invention relates to a liquid dispenser,
Referring to 'FIGS. 1 to 5 of the drawing, the reference
numeral :10 designates the neck of a glass bottle provided
with conventional external threads 11 on the end thereof.
The liquid dispenser is generally designated 12 and com

Various other objects and advantages of the present in

bottle. The liquid dispenser may also be secured in the
bottle by cement, if desired. A conventional elongated
cup-shaped cap 31 is threaded on the neck of the bottle,
as shown in FIG. 4, so that the bottle has the liquid dis
penser stored therein. A sealing gasket or washer 32 is
provided in the cap to prevent leakage of liquid from the
bottle through the spout when the cap is disposed on it.
