PROVISIONAL SPECIFICATION.
Improvements in or applicable to Vessels for Preserving Food, or
for Sterilising or Disinfecting Articles by Heat.
We JOSEF RAAB, Doctor of Medicine and FRANZ BINGLER, Surgical
Instrument Maker, both of Ludwigshafen on the Rhine, Germany, do hereby
declare the nature of this invention to be as follows:-
Our said invention relates to improvements in the construction of vessels to be
used for preserving all kinds of food stuffs particularly fruits without addition of
foreign bodies also liquids of various kinds as well as for sterilising large masses of
and also for producing material for bandages free from germs as well as for
disinfecting wearing apparel and bedding. In all these processes the most
important feature is to obtain a safe and impervious closure of the cover of the
vessel.
According to our said invention we apply to the edge or thickened rim of the
opening of the vessel a sealing ring. After filling the vessel a lid having a raised
edge or rim fitting the sealing ring is placed thereon and temporarily held in
position by clamps. On the lid is a capsule with openings covered externally by a
band of caoutchouc or other suitable elastic material.
On heating the contents of the vessel for some time the air escapes through the
openings in the capsule while the germs in any air which remains in the vessel are
destroyed by the heat.
When the vessel is then allowed to cool the pressure of the external atmosphere
presses the rubber band into the openings in the capsule and also presses down the
lid on the sealing ring thus hermetically closing the vessel. The compression of the
sealing ring causes the temporary clamps to lose their hold and they fall off.
The shape and proportion of the vesseis and of the lid may be varied to suit the
special purposes to which they are to be applied.

We JOSEF RAAB, Doctor of Medicine, and FRANZ BINGLER, Surgical

declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement and accompanying drawings:
Our said invention relates to improvements in the construction of vessels to be

foreign bodies also liquids of various kinds as well as for sterilising large masses of

important feature is to obtain a safe and impervious closure of the cover of the
vessel.
According to our said invention we apply to the edge or thickened rim a of the
opening of the vessel A a sealing ring b. After filling the vessel a lid d having a
raised edge or rim fitting the sealing ring is placed thereon and temporarily held in
position by clamps c. On the lid is a capsule e with openings covered externally
by a band of caoutchouc or other suitable elastic material.
On heating the contents of the vessel for some time the air escapes through the
openings in the capsule while the germs in any air which remains in the vessel are
destroyed by the heat.
When the vessel is then allowed to cool the pressure of the external atmosphere
presses the rubber band into the openings in the capsule e and also presses
down the lid d on the sealing ring thus hermetically closing the vessel. The
compression of the sealing ring causes the temporary clamps c to lose their hold
and they fall off.
The shape and proportion of the vessels and of the lid may be varied to suit the
special purposes to which they are to be applied.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
1. The means for preventing access of air to vessels from which it has been
expelled by heat substantially as and for the purpose set forth.
2. The combination of the sealing ring the lid d the perforated capsule e and
the elastic band for utilising the atmospheric pressure in sealing a vessel
substantially as set forth and shown.
3. In sterilising and the like processes temporarily securing the lid d by clamps e
while air is issuing substantially as set forth.
