Improvements in or in connection with the Stoppering of Bottles
and other Vessels.
I, LOUIS MATHIEU GUSTAVE JEAN LOUSTALOT, of 95 Boulevard Beau- .
marchais, Paris, France, do hereby declare the nature of this invention to be as
follows.
This invention relates to means of tightly closing the mouths of bottles and other
vessels, after expulsion of air from them, so that their contents are preserved for
long periods. For this purpose I form the neck of the bottle or vessel with a
coarse screw thread having above it a shoulder on which I place a ring of
caoutchouc or other suitable packing material. On the bottle month place first
a disc of perforated metal of a kind which is not affected by the contents of the
bottle, and above this I place a capsule of sheet metal made with an outwardly
projecting flange which tests on the caoutchouc washer, I then screw on to the
bottle neck a screw threaded shell of sheet metal which has a flange projecting
Inwardly over the flange of the capsule, thus holding it tightly down. As in most
cases it is desirable to expel air from the contents of the bottle or vessel, I
On beating
provide on the capsule a projecting nipple with a pin hole through it
the bottle or vessel, by submerging it in water or other liquid and gradually raising
the temperature, the air escapes through this hole, which is then closed by
pinching the nipple, and a partial vacuum being formed in the bottle or vessel ou
cooling. the capsule is held tightly down by atmospheric pressure. The cooling,
especially when considerable heat has been applied, is eflected by gradually
adimitting cold liquid at the bottom and allowing the hot liquid to flow away at
the top of the heating tank, the risk of fracture of the bottles or vessels being thus
greatly reduced. The perforated metal disc serves to guard the pin hole of the
capsule against being closed by any of the contents of the bottle or vessel,
the bottle or vessel contains liquid which might be affected by agitation during
transport, such for instance as milk, I completely fill in the following manner.
I provide a vessel having a screw threaded hole through its bottom into which
I screw the neck of the bottle after it has the capsule secured on it by the screwed
shell. I put in this vessel heated milk in quantity sufficient to more than cover
the capsule which for this purpose has a second nipple, I pierce this nipple and
thereupon the milk is drawn by the vacuum into the bottle so as completely to fill
it; I then close the hole by pinching the nipple.

I, LOUIS, MATHIEU GUSTAVE Jean LouSTALOT, of 95 Boulevard Bean-
marchais, Paris, France, do hereby declare the nature of this invention and in what
manue the same 18 to be performed, to be particularly described and ascertamed
in and by the following statement
This invention relates to means of tightly closing the mouths of bottles and other
vessels after expulsion of air from them, so that then contents are preserved for
long periods. For this purpose I effect the closing of a bottle as I shall describe
. referring to the accompanying drawings
Fig. 1 is a section of the upper part of a bottle with means of stoppering
according to my invention applied to it.
Fig 2 shews the cap bulged inwards when a partial vacuum is formed within
the bottle.
Fig. 3 shews means of completely filling with liquid, without access of air.
The neck A of the bottle is made with a coarse screw' thread to receive a
threaded metal capsule D which has an internally projecting hip d overlying at c an
externally projecting lip of the cap C, which by screwing down D is firmly pressed
oua caoutchouc washoi B sented on the shoulder of the bottle neck. After filling
the bottle and before putting on the cap C I prefer to place over the bottle mouth
a perforated dise F which prevents solid matters from the contents of the bottle
from reaching a small hole provided a nipple G formed on the cap C. The
screwing down of the capsule D effects tight seating of the cap without requiring
any extraneous means for pressing down the cap. Instead of screwing D as
described, it might be pressed down, and, while under the pressure, have its edge
turned in under a shoulder formed on the bottle neck, so as to secure the whole
stoppering before the pressure is 1elieved The bottle charged and having the cap
fixed as shown in Fig 1 is immersed, over the cap, in water which is gently heated
up causing such au as may be in the bottle to escape by the small hole G thus
de-oxygenating the contents. When the bubbles of au cease to rise through the
water above the bottle, I close the holo G by squeezing the nipple with suitable
pincers In some cases, after deoxygenating, the contents of the bottle are heated
to a higher temperature causing the cap to bulge. The bottle is the gradually
cooled by admitting cold water at the bottom of the vessel in which the bottle is
immersed and allowing the hot water to escape by an overflow at some height
above the top of the bottle. It is to be understood that the operations mentioned,
deoxygenating, closing the nipple, heating, and cooling are carried' on in water.
During the cooling, the partial vacuum formed inside causes the cap to be bulged
inwards and pressed firmly down by the excess of the external presstite, so as to
make a perfectly tight stoppering, independently of the caoutchouc washer and
sclew The disc F, as mentioned above, prevents solid fragments contained in
the bottle from sing to stop the hole while the deoxygenating operation' is
going on.
For charging with liquid, sucu as milk, which ought to fill the bottle entirely so
as to prevent deterioration by shaking, I proceed as follows. The bottle S filled
as above described with cold milk has its capsule screwed into a hole in the
bottom of a vessel R which then is charged with hot milk above the level of the
cap. By means of a punch UI piece a hole G' in another nipple, and on with-
drawing the punch, the hot sterilised milk, in consequence of the partial vacuum in
the bottle flows in, completely filling it without any contact with air, whereupon
the hole G 13 closed Bottles thus fully charged with milk can be transported
over great distances without any churning action on the milk.

page_text: Although I have by way of example, described my invention applied to a bottle,
it is obviously applicable to other vessels, such as jars or pots, not only for liquids
but also for pickles, preserves and other preparations.
Having now particularly descubed and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim 18:
1. A stopper for a bottle or other vessel comprising a cap pressed on a packing
washer on the mouth of the vessel by a capsule, screwed or otherwise held, the said
cap being provided with a perforated nipple which, after expulsion of air from
the vessel, is closed by pinching, substantially as and for the purpose set forth.
2. In combination with the stopper above referred to a perforated disc under the
cap, substantially as described.
3. The herein described method of completely filling the vessel with milk or
like liquid, by piercing a second hole in a nipple of the cap while it is covered
by heated liquid.
