This invention relates to improvements in
paper bottles and the like, and method of manu
facture.

ing operation so that it is not distorted. As
stated, the mandrel performs the double function
of a mandrel and female die member.
This op
eration forms a supporting ledge or ?ange M5 for
a disk-like type of closure ll as shown in Fig, 13.,
It will be noted that there is a slight space or
clearance shown at I8 in Fig. 13 between the cy~
lindrical side portion of the top member and the
conical wall of the container which permits some
springing or expanding of the top member ad
jacent the closure supporting seat thereof when
the closure disk is forced or pushed into position.
I have not attempted to illustrate this springing
action as it would be relatively slight where all
parts are made in proper proportion, but it is of
decided advantage in the effective retaining of
the closure and in accommodating closures vary
ing in diameter.
After the top member has been applied to the
wall the bottom 28 is applied. This is formed
from a disk I9 of ?brous material, see Fig. 15. A
?ange 20 is formed on the disk and the bottom
thus formed is inserted in the lower end of the
container. The bottom wall is then crimped or ;
folded around the ?ange 28 as shown at 2%.
Adhesive is preferably used at the joint in this
operation. The means for applying the bottom
are not illustrated as suitable mechanisms for
performing this operation are known in the art.
Suitable waterproo?ng may be applied if de
sired, paraffin being quite commonly used.
