the end of the spout 10 furthermost from the threads 11

from passing beyond reach within the container when
not in use. -It has been found that a suitable dimension
for the width of this ?ange 12 is 2 millimeters, and a suit

tion be formed of a plastic material which permits the
spout to be fabricated independently of the container
with which it is to be used. As previously mentioned,
the spout may be inserted within the opening of any con
tainer merely by deforming the spout and permitting it
to spring back to its original shape. In addition, the
use of a plastic ‘material permits the formation of a
membrane over the ?ange 12 to form a safety seal.

appended claims.
