This application is made under the act of March
3, 1883, as amended by the act of April 30, 1928

l9. Suitable resinous or other anti-leakage ma- .
terials may be applied to the threads between the .
cylindrical shell l8 and the plug I9 to make the
device operate more e?ciently.
Having-thus described my invention, I. claim: ‘
1. In combination, a hermetically sealed con
tainer, a dip tube extending from the exterior to
the interior of the container, a tubular member
about the opening of the dip tube on the outside
closed that parasiticidal aerosols can easily and
conveniently be prepared by releasing to the at 10. of and integral with the container, a plug thread

attached to said plug for rupturing said yieldable
seal, said plug having an escape hole longitudi

trator comprising a valve, said plug having an
illary 22 (preferably about 0.020 of an inch in
diameter) is disposed longitudinally through the
plug H). A short piece of tubing 23 is removably
disposed between the bottom of the plug I9 and
the tube I5 to prevent accidental puncturing of
the seal ll before initial use. When it is desired
to use the device, the plug i9 is ?rst taken out
and the tubing 23 removed. The plug I9 is then
replaced and screwed down until the seal is broken
by the penetrator. The plug I9 is then retracted
to permit escape of the liquid in the container
through the hole 22. When it is desired to shut
oil‘ this flow, the plug i9 is again screwed down to
seat the penetrator 20 in the opening previously
made by it in puncturing the seal I1. With this
arrangement, the container may be shipped after
being ?lled with the liquid under seal and. without
danger of leakage. Furthermore, when placed in
the hands of the user, dispersion of the liquid
can be controlled by simply manipulating the plug 60.
