Further objects, features and advantages of the
invention will appear from the following speci?ca
tion and claims, taken in connection with the
accompanying drawing, in which:
Fig. 1 is a perspective view of the cup ; and
Fig. 2 is an enlarged cross-sectional view show 30
ing in more detail the upper or lip portion of the
cup viewed along the line 2-2 of Fig. 1.
'
Referring to Fig. 1 of the drawing, the cup
shown is formed from a circular disc of relatively
thin paper of a character well understood by those
skilled in the art. The disc is folded, by well
known mechanism, into cup form providing a substantially circular bottom I and pleated side wall

to the bead ii, which presses down upon the inner
vrim of the lower lip forming a seal between the
cup and the lip. The portion of the bead offset
above the upper surface of the ?ange 5 enables
the upper lip of the user to grip the cup and,
while holding it between the lips, press the lip
portion down upon the lower lip to effect the
above-mentioned seal formed by' the under sur
face of the bead 6.
Furthermore, the outwardly ?aring ?ange in
combination with the particular formation of the
bead provides improved rigidity at the lip of the
cup and materially strengthens the cup side wall
structure.
