A large number of different styles of nesting type lids
have been developed.
In general, such lids include a
central mouth spanning portion 35 and a peripheral rim
36 which extends upwardly from the mouth spanning
portion, and the rims frequently terminate in an out
wardly directed ?ange 37 which is adapted to overlie the
upper edge of the cup or container when the lid is mounted
thereon. In some nesting type lids, the rims extend sub

particularly when the pressure is applied to the unsup
ported ?ange portion 37 of the lids. It has been found,
however, that relatively higher pressures can be applied
to the peripheries of the lids adjacent the mouth spanning
portion 35 thereof without causing permanent distortion.
However, the lid pusher elements 33 must engage the
?ange portion of the lids, in order to enable the lids to
drop down into the cup C after the lids have been moved
off the support plates 31 and 32. Accordingly, a lid

The lid pusher ?nger 61 is mounted for horizontal

light weight material such as plastic, paper or thin metal 15 from the path of movement of the pusher elements 33 on

prevent proper seating and sealing on the cup. Such
