Complet Specification Left, 19th Oct., 1895-Accepted, 23rd Nov., 1835
Improvements in Air-tight Receptacles, suitable for Holding
Sterilized Surgical Dressings and other Goods.
1, SEVERIN IMMENKAMP, Manufacturer, of 30 Emilienstrasse, Chemnitz, in
the Kingdom of Saxony, do hereby declare the nature of this invention to be as
follows:-
Airtight receptacles for surgical dressings have hitherto been made of sheet-
metal, and are therefore either expensive, or troublesome to open.
To avoid these drawbacks, I make the sides of the cylindrical receptacle of
parchment paper or similar air and water-tight material, the upper and lower
edges being turned outward, so as to form at the top and at the bottom of the
receptacle a circular flange suitable for securing to it a lid of sheet metal. The
ends of the sheet of parchment paper are made to overlap each other and form
an airtight joint.
The sheet metal plates which form the top and bottom of the receptacle are
preferably corrugated, and connected with the flanges or borders of the parchment
paper by swaging, rolling or other means suitable to make an airtight joint.

Improvements in Air-tight Receptacles, suitable for Holding
Sterilized Surgical Dressings and other Goods.
1, SEVERIN IMMENKAMP, Manufacturer, of 30, Emilienstrasse, 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 :-
Air-tight receptacles for surgical dressings have hitherto been made of sheet-
metal, and are therefore either expensive, or troublesome to open.
To avoid these drawbacks, I make the sides of the cylindrical receptacle of
parchment paper or similar air and water tight material, the upper and lower edges
being turned outward, so as to form at the top and at the bottom of the receptacle
a circular flange suitable for securing to it a lid of sheet metal. The ends of the
sheet of parchment paper are made to overlap each other and form an air-tight
joint.
The sheet-metal plates which form the top and bottom of the receptacle are
preferably corrugated to act as a spring, and connected with the flanges or borders
of the parchment paper by swaging, rolling or other means suitable to make an
air-tight joint.
Cylindrical cases, such as are shown at a in the accompanying drawings, are
formed of parchment or of paper, or cardboard made damp-proof, with turned

page_text: down edges or flanges, and with an air and water-tight joint or seam, b, fastened
by some suitable adhesive substance or cement.
The bottom pieces, c¹, c², are cut out from sheets of metal by means of suitable
dies, and are spring fitted in the cylindrical wall or casing by means of either a
single or a double groove or corrugation; the contents of the case being sterilized
before the bottom plates are thus fitted in position.
A packing medium obtained in this manner will effectively protect the articles
packed from atmospheric influences, and keep out dampness and bacilli while
offering the additional advantages of being of very small weight and far less
expensive than the sheet-metal cases. Besides, it possesses the further merit-and
one by no means to be under-rated-of only requiring the use of an ordinary
knife, a pair of scissors, or any other sharp or pointed instrument, to be opened.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.―
A case for packing dry sterilized material for dressing wounds, obtained by
first forming a cylindrical tube or casing, such as a, of parchment, air- and water-
proof paper or cardboard, or similar material; providing it with an air- and
water-tight joint by fastening together its longitudinal edges with a suitable
adhesive substance; turning down its edges at the ends, and spring fitting sheet-
metal bottom pieces, such as c', c³, thereto, the said pieces having, if desired,
either a single or a double groove or corrugation; the contents being, if desired,
sterilized before the bottom pieces are secured in position, substantially as
described and shown in the drawings.
