The present invention relates- toimprovements
infcontainers, and more; particularly to a- ñat cir
cular container of a kindV commonly used to con
tain? cosmetics,y such.. as» for example powder,
rouge, etc..
Containers ofi the kind to-Which this invention
pertains- usually include a shallow circular bot
tom portion anda circular top» or cover portion
hingedly connected». together at their peripheral
edge in suchma-nner as to~enable the cover por
tion` tofbemoved about a~ pivot/into an open or
closedY position. The» bottom and cover portions
are eachiashionedy in a single piece. from suitable
shapeV retaining, ma-terial, such as for example
p1astics,.wood„ bone, metal, or the like; and in
meanssto-r causeÓ said coverr to” be-'urgedV into a» fully- -
closed positioni or aiullyfopened position upon-the
initialvapplicationof force only.

edge 2B of its depending portion 26 bears tightly
against the iiap extension 24 on the bottom por

As previously noted hereinabove, the cover Dor
tion I2 is connected to the bottom portion II in‘v
such manner as to be moved in an arc towardsV
When the cover portion is to be moved
»into open position, the initial resistance of the
and away i'rom said bottom portion, preferably ' ` flap 24 is overcome whereupon said flap again acts
as by means of a hinge generally indicated at 2l. '
This hinge has its complemental parts formed
integral with one or the other of the two con--`
tainer parts and, as best illustrated inY Figs~ 3'
to 6, it includes a pair of spaced ears 22 extend
ing outwardly radially from the peripheral edge'
of the bottom portion II. These ears preferably
constitute continuations‘ of the reinforcing rib
.upon the depending portion 26 to urge the cover
linto its fully opened position, as illustrated in
Fig. 6. Thus it Will be observed that applicant
' has provided a hinged structure embodying novel
structural characteristics affording means to in
sure a full closing of the container and full open
20 ing thereof with the application of but a mini
mum amount of effort.
The cover is retained in its closed position by
frictional coaction between the outside surface I5
are each formed with a slot 23 on their inwardly
of the circular flange I4' and the inside wall of
disposed'rfaces, and said slots 23 open' upon the
bottom edges of said ears for a purpose to be 25 the cover recess I9. Such frictional coaction is

ing rib I6 is provided, at the end merging with

hinge element 25 during the closing operation at
which time the circular wall of the recess I9 is
forcibly urged downwardly over the outside sur

edges of said ears.- -The continuation 24 of the
ribr I6 is-separated from the ears 22 by slots 25 Vso
as toïthereby be entirely free of said earsV and
thereby be capable of flexing Aoutof its normal

the lingers of the user, to the opposed shoulders
I'I and 29 at the ends ofthe reinforcing ribs I6
and I3 respectively, which force is suñicient to
cause initial separation of the cover from the
' circular ñange I4, whereupon the resiliency’of
the hinge element effects further opening into
fully opened position.
`It should be apparent that applicant has pro

ficient width to extend freely into'the peripheral
recess between the ears 22 on the bottom portion
II when the cover is mounted over the bottom
portion.,y The part 26', which constitutes one ele,
ment of the hinge structure; is formed on its'lat
eral edges, and‘ adjacent its bottomY edge, Vwith
outwardly extending bearing portions 21' which
extend into and are journalled within the bearing
tures particularly` intended to simplify the oper

costs of manufacture and that the invention is

A container having a bottom portion' and a
cover portion, a pair of ears extended outwardly

from an edge of the bottom portion, a bearing slot
Upon reference to Figs. 5 and 6, it will be noted
on the inside face of each ear and opening- onto
that the coverv portionv I2 is hingedly mounted,

an edge of the cover portion disposed between said, Y

in the bottom portion lying in the bottom plane’
with respect to said bottom portion. Assembly
