PROVISIONAL SPECIFICATION.
Air-tight Packing Coverings and Tool for use in Closing the same.
I, FERDINAND STELZNER of Alter Wandrahm, Hamburg, in the German Empire,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to the production of an air tight packing covering or casing
and to means for closing the same. The covering consists of an outer and an inner
cylinder of cardboard or other suitable stiff material. Between these two cylinders
there is a third cylinder of pliable material such as cambric paper connected by each of
its ends to the top ends of the two cardboard cylinders. A fourth cylinder of pliable
material is attached to the bottom end of the inner cardboard cylinder.
The tool for effecting the closing operation consists of a hollow body open at
bottom and having at top a central orifice. Within this body and so as to be
displaceable up and down like a slide is arranged a pincer or tongs with the handle
ends projecting out from the bottom, whilst the jaws come in front of the upper
central orifice.
To pack goods the tool is inserted in the cylinders and slid nearly up to the end of
the fourth or innermost cylinder, the outer end of which is then folded over and
passed through the upper central orifice of the tool, held fast there by the pincer and
the casing turned round on its axis. As the fourth and innermost cylinder is in firm
connection with the inner of the two cardboard cylinders and its opposite end firmly
held by the pincer, it will upon the turning on its axis of the inner cardboard cylinder
be wound up closer together until an outwardly air tight covering is formed. When
this is done the pincer released and the tool withdrawn from the casing which is
then filled up to the edge of the inner cardboard cylinder, upon which the outer
carboard cylinder is then turned. The ends of the second or intermediate pliable
cylinder upon this, by reason of their connection to the two cardboard cylinders are
turned in opposite directions round their axis. Whilst the outer cardboard
cylinder is being turned round the intermediate pliable cylinder becomes shortened
and the outer cylinder slides lengthwise and crosswise over the inner cardboard
cylinder. The turning is continued until the two cardboard cylinders come flush with
each other when the package is closed.

COMPLETE SPECIFICATION.
Air-tight Packing Coverings and Tool for use in Closing the same.
I, FERDINAND STELZNER of Alter Wandrahm, Hamburg, in the German Empire,
Merchant, 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:-
This invention relates to the production of an air tight packing covering or casing
which may be readily opened and closed again and to means for closing the same
without the use of capsules glue and other material ordinarily employed for such
purposes.
In the accompanying drawing Figs. 1, 2, 3, 4, 5, are views of the connected parts
which form the covering and Figs. 6, 7, 8 views of the tool for use in closing the
same.
The covering consists of an outer cylinder o and an inner cylinder p. capable of
sliding and turning the one within the other. Both cylinders are made of cardboard or
other suitable stiff material. Between these two cylinders there is a connection in
the form of a third cylinder t made of pliable material such as silk paper, cambriç

paper; tissue paper, etcetera, attached by its ends to the top of each of the two
cylinders o, p. A fourth cylinder or cap s is attached to the bottom end of inner
cylinder p.
The tool used in the closing operation consists of a hollow body open at bottom
sand having at the top.d a central orifice e.. Within, this body, and so as to displaceable
up and down within certain limits like a slide, is arranged a pincer or tongs with
the handle ends projecting out from the open end of the hollow body whilst the
jaws y come in front of the upper central orifice e. A spring holds the pincer
open..
To pack goods the tool is inserted-in-cylinder p (Fig. 8) and slid nearly up to the
end of cylinder s the outer end of which is then turned round to fold it together and
passed through orifice e; held fast there by the pincer and cylinder p turned round
on its axis.. As cylinders is connected to cylinder p and its opposite end firmly held
by the pincer, it will upon the turning of cylinder p be wound or folded up and
finally after a sufficient number of turns thereof an outwardly air tight covering
formed, the silk paper or other thin pliable material being wound or folded up closer
and tighter with every turn, the folds running from the periphery to the axis. When
this is done, the pincer is released and the tool withdrawn from cylinder p. The
result of this manipulation partly effected is shewn in Fig. 1 and complete in Fig. 2
where, cylinders has been formed into an air tight cap or end for cylinder p which is
now filled with goods to its upper edge and the cylinder o turned round on cylinder p
when the ends of the second or intermediate pliable cylinder t are turned in contrary
directions round their axis and taking up the form shown in Figs. 3, 4. As the
cylinder o is turned round the cylinder is shortened causing the former to slide
down over cylinder p. The turning operation is continued until the cylinder p is
completely inserted in cylinder o as shewn in Fig. 5, that is to say until the package is
complete. In this position of the cylinders o, p the two ends of the pliable cylinder t
form two covers lying one over another and closing air tight.
The covering serves not only for keeping goods until sale is effected but also for
intermittent use as it may at any time be opened by turning cylinder o on cylinder p
and closed again by turning in the reverse direction to form an air tight closure.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim, is:
1. An air tight packing covering formed by providing. one of two cylinders o, p,
inserted one within the other and connected together by a thin pliable cylindrical
connection, with a closed end either in a known way or, in the way that the free end
of a pliable cylinders is held fast and the cylinder p rotated and after filling one
cylinder with goods turning each in opposite directions on their axis or by holding
one fast and turning the other so that the pliable connection between the cylinders is
turned on the axis of the same thereby forming an air tight closure substantially as
described and shewn.
2. For the purpose of carrying out the packing operation referred to in claim 1 and
for proserving the packet goods in an air tight, readily opened and closed covering the
arrangement of two cylinders o, p, sliding one into the other, to the upper ends of
which the ends of a pliable cylinder of silk paper or other thin paper are fixed
substantially as described and shewn."
3. The tool for use in closing air tight the end of cylinder p consisting of hollow
body with orifice at top and a pincer or tongs sliding or displaceable within the
same substantially as described and shewn."
