2 Claims. (Cl. 21S-100)
The instant invention relates to removable container
closure devices.
More particularly, it relates to a cover
assembly mechanism for sealing containers during vac
uuin ñlling, and which permits rapid uncovering of a
container after filling for substitution of another con
of the cover.
FIG. 3 is a View taken substantially on the line 3-3
of FIG. 2 and looking in the direction of the arrows.
FIG. 4 is an elevational view of -the device with parts
broken away for the purpose of illustration.
FIG. 5 is a View taken substantially on the line 5-5
of FIG. 4 and looking in the direction of the arrows.
Referring now more particularly to the drawings, the
container 10 illustrated in the instant embodiment is what
has been referred to previously as a trap bottle. The con

In accordance with the instant invention, and as an
object thereof, there is provided a cap or cover assembly
which is adapted to seal and unseal successive contain
ers by means including cam surfaces.
Itis a further object of the invention to provide a cover
or closure assembly for successive containers adapted for
use in the heretofore described fashion and which com

strength and rigidity in the suspender or holder 14.
Having reference to FIGS. 3 and 4, it is seen that the
inner surface of the holder is formed to accommodate
the ’beads 20 and 21. For such purpose, integral with
and extending inwardly of the holder for disposition be
tween the beads 2i? and -21 is an arcuate flange 22 which
is adapted to seat between beads 2% and 21. This ñange
22, when positioned as illustrated in said FIGS. 3 and 4,
is adequate to suspend a container from the suspender
or holder 14. Flange 22 is disposed at a height from
the bottom 23 of the holder 14 which will cause the
flange 22 to engage between the beads 2i) and 21 when
the bottom 23 engages the shoulder 24 of the container
tightened to the container or released therefrom.

The device operates in the following manner: A trap
bottle, such as container 1G, is shoved into the resilient
holder 14 and almost automatically, because of the radius
of curvature thereof, the container becomes suspended
from the holder with the liange 22 seating between beads
2li and 21.
