Application March 5, 1937, Serial No. 129,185
3 Claims. (Cl. 215—38)
This invention pertains to closure caps and
more especially to such as are designed for the
~ closing of milk bottles. Among the objects of
‘this invention are the provision of a cap which
5 can be manufactured and sold for a less price
than the most popular caps now on the market;
to provide a. cap of the character indicated which
will aiford a greater degree of sanitation than
the previously manufactured caps; to provide a
10 cap which will furnish a perfect seal for a stand
ard milk bottle; to provide a cap which will re
duce to a minimum the space on the top of the
cap wherein water and dirt can collect; and such
further objects, advantages, and capabilities as
15 will hereafter appear and as are inherent in the
construction disclosed herein.
In the drawing annexed hereto and forming a
The rib 1 also furnishes a fulcrum about which
the channeled rim of the cap may operate when
a pull is exerted on the rib or bead 3 tending to 15
remove the cap from the bottle. ° The effect of
such a pull is to tend to draw the part 6 out
in theappended claims.
Having now described my invention, I claim:

with a deep top opening, such as shown in this to rest upon the bottle ledge and close the mouth
of the bottle, a channeled rim, continuous with

grooved portion 2 adapted to fit closely the pour

The inner portion of the grooved rim is ex
of the bottle, a rim continuous with said central
tended inwardly in the form of a v?at ring 4 section rising to the top of the bottle mouth and
which rests upon the ledge I of the milk bottle extending outwardly and downwardly around the
to close the mouth thereof. The central portion
of the cap is dome shaped, as indicated at 5,
which permits easier application of the cap to a
bottle, the upright wall 6 of the cap being slightly
55 larger in diameter than the corresponding wall
of the bottle so that it is necessary for this to
contract somewhat when the cap is being placed
upon the bottle. This furnishes an outward pres
sure upon the mouth of the bottle to hold the cap
in place after it has been inserted.
