'This invention relates generally to packaging,
and pertains particularly to an improved package
and closure therefor, adapted for the packaging
of liquids and other commodities.
A primary object of_ the invention is the pro
a closure of the construction illustrated in Fig. 1
secured thereto;
Fig. 6 is a sectional elevation corresponding to
Fig. 5 and showing the relationship of the closure

re-use in the original condition, although per
mitting the continued use of the closure as an
effective stopper for the container.
Another object is the provision of such a closure
which will form an hermetic seal on an appro
priate container, and which is not subject to

of closure embodying the invention.
For the packaging of liquors or other commod- 10
ities it is frequently desirable to employ a pack
age of such character that it may be immediately
ascertained whether or not it has been opened.
It is quite desirable that the closure or stopper
for the container be of such character that it may 15
be continued in use, after its initial removal, to
form an eiîective closure for the container, and

Such devices do not adequately fulfill their `~
purpose due to the fact that the sheaths are of '
relatively simple character and separable from
the stopper, thus permitting the package to be 30
restored to its original and unopened appearance
simply by the application of a new sheath to the
container and the original stopper.
The present invention provides a closure in
which the sealing element is of distinctive char- 35

As seen in Fig. 1, the closure comprises a

sleeve gasket I2 therein, and a holding member 50

Fig. 3, comprises a cap or shell formedof a suit

a top pmel I5, which is domed upwardly in its
central part, and a peripheral skirt or flange por

glnal portion of the skirt is turned inwardly to
10 form a, flange I8 which covers the lower edge of
the gasket I2.
The gasket I2 is of sleeve form and is made of
a suitable soft but strongly elastic material, such
as rubber. It is held under circumferential con
striction or compression by the skirt of the shell,
so that it conforms to the contour thereof in the

internal diameter of the balance of the constrict

with a peripheral ledge 3| which is of a diameter
such-as to ñt within the lower cylindrical portion
23 of the closure sheath. This ledge 3| is spaced 15

diameter such as to receive the same sn'ugly. It
has a top portion 20 from which depends an an
nular skirt, said skirt being formed with -flutes
2| which extend for theÍ greater portion of its
depth from-the top portion, leaving the lower
portion 23 in cylindrical form. The inwardly
30 offset portions of said flutes terminate at sloping
surfaces 22'which are inclined inwardly and up
wardly at the same angle as the flaring portion
IG of the sealing closure.

After the container has received its contents
the-closure is placed upon its mouth, the mouth 20
rim entering slightly within the lowermost flaring
portion of the gasket I2.
Downward pressure is ,

to seated positionl on the container, in which
position the lower limit of thc sealing closure 25
shell is slightly above the ledge 3| and the top
panel I5 is in contact with the mouth rim of
the container, as seen in Fig. 5. In this forcing
of the closure to seated position, the- pressure ap
plied to the top of the sheath is transmitted di 30
rectly to the top of the sealing closure shell, and
also, through the medium of the flutes 2|, to the
flaring portion I 6 of the sealing closure shell.

The downward movement of the closure relative
to the container causes a wedging action to be 35
exerted upon the elastic gasket, causing it to be

is applied to the central portion of its under
surface.
In assembling the closure from the parts above
formed between the container and the closure.
Such seating of the closure upon the container
brings the lower margin of the sheath skirt to a

The holding member I4 is in the form of a ñat
metal plate of generally circular outline and of
tion, the holding member I4 is inserted into the
sheath so that it comes to rest against the inner
surface of the sheath top, and the sealing closure
II is then inserted into the sheath until its domed
top portion comes into contact with the drop of
solder 25. Heat is then applied to the domed
portion over the drop of solder, fusing the latter
and soldering the sealing closure shell to the
holding member I4.
The sheath is then subjected to a punching or
slotting operation by which portions of its skirt

position somewhat 'below the peripheral ledge 3|,
locking the closure to the container. The pack
age is thus hermetically sealed and cannot be
opened without obvious mutilation.
In order to open the package,. the narrow
strands 28 are severed, as with a knife or other
thin object, Since these strands occupy a posi
tion between flange I8 and the ledge 3|, the sev
ering of them is easily accomplished by inward
pressure, and the severed margins are bent in

After having been thus removed, the sealing

of apertures 21 running circumferentially thereof sheath, and may be re-applied by pressing it down
at an appropriate distance above its lower mar
gin. Said apertures are separated by narrow
strands 28 of the sheath metal, which strands con
stitute the sole remaining connection between the
cylindrical lower portion of the sheath skirt and
the ñuted upper portion in which the sealing
closure is ipermanently secured.
The closure is thus in condition for applica
' onto the mouth of the container, where the com
pression of the gasket holds it securely in place.
Re-application and subsequent removal of the
closure are facilitated by giving it a rotary move
ment, and this manipulation is facilitated by the
depth and iluting of the sheath. In such opera
tion the sealing closure is positively held against
rotation in the sheath due to the interengagement

of the holding member I 4 with the flutes of the
latter.

In the modiñed form of closure shown in Fig. 7
the sheath is designated generally by the refer
ence numeral I0'. The sheath skirt is originally
formed with two outside diameters, the upper
portion of the sheath skirt being formed with the
inwardly oifset ilutings 2l' as above described,
and the lower portion originally being on a
K10 larger radius as shown in dotted lines at 23' and
being united with the upper portion by an annu

the sheath is retained in cylindrical form, as
shown in the full line position in Fig. 7, and is
a. punched at intervals, as above described, to form
the retaining elements 26' which are bent inward

the sealing cap. Such punching forms the nar

the container as above described, and is operable
for removal and re-application in the manner
above described.
