PROVISIONAL SPECIFICATION.
Improvements in Receptacles for Sterilized Surgical Dressings and
other Goods Requiring the Exclusion of Air.
I, SEVERIN IMMENKAMP, Merchant, of Innere Klosterstrasse 13, Chemnitz,
in the Kingdom of Saxony, do hereby declare the nature of this invention to be as
follows:-
The sheet metal boxes commonly used for packing sterilised surgical dressings,
such as bandages and wadding, have an undivided cylindrical sheet metal shell,
and holes are cut in the centre of the bottom, which after sterilisation of the
contents are closed by soldering.
During the process of soldering, impurities may easily get into the interior,
and the operation takes so much time, that atmospheric air charged with microbes
may again penetrate into the dressing and render the sterilisation illusory.
To avoid these drawbacks, I make the shell or circumference of the box of
two parts or lengths of equal cross sections (which in the case of an ordinary
cylindrical receptacle is a circle), and unite them by means of butt joints. The
joint is covered with a sheet metal strip soldered on in such a manner, that
it can be easily torn off by means of a special instrument, when it is desired to
empty the box.
The two parts of the shell may have the same length, equal to half the length
of the box, or they may have different lengths. Their cross sections may be
circular, oval or of other suitable shape.
The ends are swaged on to the side or shell of the box and are preferably
corrugated. The end plates may be lined internally with discs or sheets impreg-
nated with antiseptics, and a suitable packing material is inserted between the
edges before the end discs are swaged on to the sides.
Dated this 5th day of February 1895.

Improvements in Receptacles for Sterilized Surgical Dressings and
other Goods Requiring the Exclusion of Air.
I. SEVERIN IMMENKAMP, Merchant, late of Klosterplatz, now of 30 Emilien-
strasse, Chemnitz, in the Kingdom of Saxony, do hereby 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 :—
The sheet metal boxes commonly used for packing sterilized surgical dressings,
such as bandages and wadding, have an undivided cylindrical sheet metal shell,
aud holes are cut in the centre of the bottom, which after sterilization of the
contents are closed by soldering.

page_text: During the process of soldering impurities may easily get into the interior, and
the operation takes so much time, th atmospheric air charged with microbes
may again penetrate into the dressing and render the sterilization illusory.
To avoid these drawbacks, make sheet metal boxes as hereafter described
and represented by the accompanying drawings Figs. 1 & 2.
The circumference or shell consists of two parts a and b, of equal cross section,
which have either a butt-joint, as in Fig. 1, or a lap-joint, as in Fig. 2, and
are provided with flanges, as shown. The cover and bottom are fixed by folding
their edges cover the circular end flanges of the shell.
The joint is covered with a sheet metal strip d, soldered on in such a manner
that it can be easily torn off by means of a special instrument, when it is desired
to empty the box.
The two parts of the shell may have the same length equal to half the length
of the box, as represented by Fig. 1, or they may have different lengths, as
represented by Fig. 2, in order to use one part as a cover. Their cross sections
may be circular, oval, or of other suitable shape. For the sake of clearness the
thickness of the shell is exaggerated in the drawing.
The ends are folded with their edges on to the side or shell of the box, and
are preferably corrugated. The end plates may be lined internally with discs
or sheets e, impregnated with antiseptics, and a suitable packing material is
inserted between the edges to render the box air-tight before the end discs are
secured to the sides.
Having now particularly described and ascertained the nature of this inveu-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
A sheet metal box suitable for sterilized surgical dressings, having this
distinctive feature-that the bottom or end plate is folded with its edge on to
the flanged side and composed of a single piece c of sheet metal internally lined
with an antiseptic disc, while the side or shell consists of two cylinders a, b of
equal or unequal length, said cylinders having either a butt-joint or a lap joint
covered with a detachable sheet metal strip d, substantially as described.
Dated this 1st day of November 1895.
