I, LUCIEN FREMY, of Chalonnes-sur-Loire, Department of Maine and Loire, in
the Republic of France, Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:―
The apparatus forming the subject of this invention is primarily designed for
the sterilization of liquids, while at the same time it is intended to serve as a
container or receiver for such liquids, pending their ultimate exhaustion or con-
sumption.
The invention will be best understood by reference to the accompanying
drawings, in which
Figure 1 is an external front elevation;
Figure 2, a vertical section;
Figure 3, a plan, and
Figure 4, an inverted plan of the improved apparatus.
The improved apparatus consists of a tube T of unoxidizable metal, provided at
each end with an externally screw-threaded strengthening or stiffening ring t, 2,
adapted to receive interchangeable closing devices 0 and 0.
One of these, 0, termed the upper closing device, is fitted with two suspension
rings and with a tap R which is surmounted by a hollow cylindrical piece F.
screw-threaded internally, so as to be capable of receiving a screw-stopper B.
The device 0, termed the lower closing device, carries a tap R.
0
These two closing devices 0 and 0' consist cach, of a spherical cap or done,
with its concavity turned towards the interior of the apparatus; which cap or
dome is provided with a tappet ring assuming the external shape of a nut and
adapted to be screwed on to the externally threaded rings of the tube T. In
the centre of the dome or cap there is provided an aperture, which is also tapped,
and fitted to receive a screw-threaded collar forming part of (or secured to) the
flange of each of the taps R R. Within the dome there is brazed a projecting
metal ring k, the outer diameter of which is equal to the inner diameter of the
tube T, so that, in conjunction with the ring o, it forms a groove wherein there
engages with slight friction the rings t t¹. At the bottom of the groove there is
embedded a band C, of suitable compressible material, upon which firmly bear the
[Price 8d 1

so that a tight joint is ensured.
When it is desired to use the apparatus for sterilizing liquid, such liquid is
admitted into the tube T through the upper end, while the opposite end has the
closing device (1 fitted to it, the tap R of which is closed. When the desired
quantity of liquid has been admitted, the closing appliance is screwed on to the
ring and the tap R is closed also.
Upon the completion of the sterilization by any convenient method an anti-
septic plug D is inserted into the hollow cylinder F, and compressed, by screwing
home the threaded stopper B, then the two plugs of the taps R R are connected by
a wire, fastened with a lead seal, for which purpose a small hole is formed in the
said plugs.
As a result of these operations a perfectly tight closing of the tube T, and one
that cannot be tampered with, is obtained
When it is desired to make use of part of the liquor contained in the tube T and
protect the remaining part from spoiling, it is necessary to keep any impure air out
of the tube.
This result is attained by the arrangement hereinabove described: in order to
draw off the whole or part of the liquid, the screw-stopper B is first removed, after
which the two tas R and R are opened. The liquid will then flow out through
the lower tap R', while external air will be drawn in, by aspiration or suction,
through the upper tap. The air, however, before entering the tube T passes
through the antiseptic plug D, placed within the hollow cylinder F, and is, there-
fore, filtered and purified when it does enter, so that it cannot contaminate the
liquid preserved in the tube T.
When a sufficiency of liquor ir drawn off, it is only necessary to close both taps R
and R, and to screw the stopper B in place.
Owing to the facility with which the several parts, constituting the sterilizing
apparatus which forms the subject of this invention, may be disconnected, they
may be readily cleaned and sterilized separately prior to being fitted together
for use.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. Apparatus for sterilizing liquids and containing them until wholly used up,
consisting of a tube (T) the ends of which are screw-threaded and adapted to
receive interchangeable closing devices (0) 0¹), the lower one of which (0) is
provided with a tap (R) for drawing off the sterilized liquid, while the upper
closing device (0) carries a tap (R) for the admission of air into the tube (T)
whilst liquid is being drawn off; such air being purified by passing through an
antiseptic pad or plug (1) placed in the recess part (F) surmounting the upper
tap (R); such recessed part F being adapted to receive a screw-stopper (1) sub-
stantially as described with reference to the accompanying drawing.
2. In the apparatus referred to in the 1st Claim, an arrangement for preventing
such apparatus from being tampered with, consisting of a wire whereby the plugs
of the taps (RR) of the two closing devices (0, 0), respectively, are connected
and which is afterwards sealed with lead, as above described with reference to
the accompanying drawing.
