CLOSURE AND CONTAINER
Abstract
A container has locking lugs on its open upper end and a closure
has slots registrable with the locking lugs, the closure being
rotatable relative to the container to move the slots into and out
of such registration for releasably locking the closure relative to
the container, the closure and container having nestable stacking
rings whereby, when the closure is disposed at the upper end of the
container additional containers may be stacked thereon in seriatim
and, whereby, when the closure is removed from the top of the
container and placed on the ground or other supporting surface it
may serve as a base or pedestal for supporting the container.

Claims
The embodiments of the invention in which an exclusive property or
privilege is claimed are defined as follows:
1. In combination, an open topped container and a closure therefor,
locking lugs on the container registrable with locking slots in the
closure and selectively movable out of such registration for
locking the closure relative to the container, a stacking ring
depending from the bottom wall of the container and a mating
stacking ring extending upwardly from the closure, whereby a
plurality of containers may be stacked one upon the other when the
closure is in place on the open end of the container, the locking
lugs on the container comprising a web portion fixed to and
extending upwardly from the upper end of the container and a
locking bar extending outwardly from the upper end of the web
portion in spaced parallelism to the upper end of the container, a
handle on the closure for facilitating its movement, and stacking
ribs on the exterior side walls of the container, wherein the
closure upon removal from the upper end of the container and
placement on the ground or other supporting surface may function as
a base or pedestal for the container, with the stacking ring of the
container being engaged with the stacking ring of the closure.
Description
A primary object of the invention is to provide a container and a
closure therefor with locking means whereby the two may be
releasably engaged.
Another object is to provide means for stacking multiple
containers.
Still another object is to provide a closure which can function to
close the open end of a container and which also can serve as a
base or pedestal for the container.
In the drawings:
Fig. 1 is an exploded perspective view of a container and closure
of the invention;
Fig. 2 is a fragmentary exploded perspective view of the container
and closure before assembly;
Fig. 3 is a fragmentary perspective view of the container and
closure after assembly but before locking;
Fig. 4 is a fragmentary perspective view of the container and
closure after locking;
Fig. 5 is a fragmentary perspective view showing the container and
closure stacking feature; and
Fig. 6 is a fragmentary perspective view of the container bottom
wall.
The substantially cylindrical container is generally indicated by
10 and is open at its upper end and closed at its lower end by a
bottom wall 12.
An annular stacking ring 14 depends from bottom wall 12, the
stacking ring being of smaller diameter than that of bottom wall 12
so as to be disposed inwardly of the container side walls 16, which
preferably taper outwardly from bottom to top.
Spaced, parallel vertically-extending ribs 18 are provided on side
walls 16 for facilitating the stacking of one container within
another.
A plurality of L-shaped locking lugs 20 is provided at spaced
intervals around the open upper end of the container, the locking
lugs each comprising a web portion 22 which is fixed to and extends
upwardly from the container and a locking bar 24 which extends
horizontally outwardly from the upper end of the web portion and is
disposed in spaced parallelism to the upper end of the
container.
A bail 26 is hinged to bosses 28 on the upper end of container side
walls 16 in known manner.
An annular closure 30 is adapted for releasable engagement with the
upper end of the container for closing same and for facilitating
the stacking of containers, one on top of another, as will
appear.
Closure 30 includes a flat body portion 32 having a central
stacking ring 34 extending upwardly therefrom, the stacking ring
being bridged by a cross bar 36 which functions as a handle for
manipulating the closure.
A locking rim 38, concentric with stacking ring 34, extends
upwardly from the periphery of body portion 32 and has a depending
flange 40, the inner face of which is adapted to embrace the side
walls 16 of container 10 when the closure is placed on the
container with the lower surface of the rim 38 engaging the upper
edge of the container side walls.
A plurality of slots 42 is provided at spaced intervals in locking
rim 38 of closure 30. As shown in FIGS. 2 and 3, the slots are
spaced to register with locking lugs 20 on container 10 and are of
suitable dimensions as to permit the passage of the locking lugs
therethrough when the closure is placed on the container.
As seen in FIG. 4, rotation of the closure in a clockwise direction
moves slots 42 out of registration with locking lugs 30, whereby
rim 38 of the closure underlies locking bars 24 and one end of the
slots engages web portions 22 of the locking lugs. Reverse rotation
of the closure moves the slots back into registration with the
locking lugs whereupon the closure may be removed from the
container.
As seen in FIG. 5, stacking ring 14 on bottom wall 12 of the
container fits snugly around stacking ring 34 of the closure
whereby containers may be easily and securely stacked, one on top
of the other.
Alternatively, the closure may be utilized to prevent the container
from tipping, in which case the closure is removed from the top of
the container and the rings 14 and 34 releasably engaged whereby
the closure becomes a base or pedestal to provide sturdy support
for the container.
