Improvements in Compressible Tubes for Paints, Surgical Dressings,
and the like.
I, THEODORE YOUNG KINNE, of No. 9, Church Street, in the City of Paterson,
County of Passaic, and State of New Jersey, U.S.A., Physician, do hereby declare
the nature of this invention to be as follows;-
-
My present invention relates to improvements in compressible tubes, made of
ductile and impervious metal, and which are usually provided with small dis-
charge outlets adapted to be closed by screw-threaded caps, and have their
opposite ends folded and pressed together; whenever the contents of said tubes
is to be discharged (after the screw-threaded caps have been removed), the opposite
or folded ends are compressed.
These tubes are generally used for paints, dentifrices, surgical dressings, etc..
and especially when used for surgical dressings, are sterilized together with said
dressing, so as to render said dressing perfectly anti-septic, to thus obviate the
danger of inoculating diseases to patients treated with it or to persons handling
the same.
There are a number of surgical dressings or preparations, which contain various
salts of metals such as for instance-salts of mercury, and it is an establisired
fuct, that such preparations are being quickly decomposed when put up in such
compressible tubes, (generally made of lead or analogous ductile metals, compo-
sitions, or alloys), and accordingly such dressings or preparations have to be put
up in porcelain or glass jars, or wooden boxes.
The object of this invention is to over-come the objections above referred to,
and to provide a compressible tube for the reception of surgical dressing, etc.,
and by the use of which the said surgical dressing cannot be effected or
decomposed by the metal or alloy, of which the said tube is made.
The invention consists in the improved compressible tube, having its interior
wall or surface coated with a preparation indifferent to the action of the metal
or alloy of which the tube is made and also indifferent to the action of the pre-
paration or dressing contained in said tube, substantially as will be hereinafter
more fully described.
For the above purpose the interior wali or surface of the tubes is coated with
collodion, to which has been added a small quantity of castor-oil and balsam fir.
The collodion is prepared by mixing ½ gallon of ether with ½ gallon of
alcohol, and adding 4 ounces of pyroxiЛin.

page_text: To one gallon of said collodion is added from two to three per cent. castor oil
and from one to two per cent. balsam fir.
For the purpose of coating the tubes, the same are slightly heated, and while
warm, are filled with the solution above referred to, which after remaining in
said tubes a short time, is poured out.
A certain amount of the solution adheres to the interior surface of the tubes,
and after the ether and alcohol has evaporated, forms a thin layer or coating,
which is impervious and indifferent to the action of the metal of which the tubes
are made and also indifferent to the various surgical dressings etc., placed in
said tubes.
It must also be remarked, that said thin layer or coating is ductile and will
not become detached from or blister off the tubes, while the latter are being
handled and compressed, and will not be effected by the temperature which is
used and is necessary for the sterilization of the dressing (together with the
tube).
For the purpose of completely expelling the air from the interior of the tube,
when the latter is being filled and the open end closed or folded, a small pin-
hole is provided for in the wall of the tube near its open end, and after said
open end is closed, that is to say, is compressed and folded together, the air
which still may have remained in the tube is discharged through said small pin-
hole, and the latter is then afterwards closed by the folded or compressed portion
of the tube.

Improvements in Compressible Tubes for Paints, Surgical Dressings,
and the like.
1, THEODORE YOUNG KINNE, of No. 9, Church Street, in the City of Paterson,
County of Passaic, and State of New Jersey, U.S.A., Physician, 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:-
•
My present invention relates to improvements in compressible tubes, made of
ductile and impervious metal, and which are usually provided with small. dis-
charge outlets adapted to be closed by screw-threaded caps, and have their
opposite ends folded and pressed together; whenever the contents of said tubes
is to be discharged (after the screw-threaded caps have been removed), the opposite
or folded ends are compressed.
These tubes are generally used for paints, dentifrices, surgical dressings, etc..
and especially when used for surgical dressings, are sterilized together with said
dressing, so as to render said dressing perfectly anti-septic, to thus obviate the
danger of inoculating diseases to patients treated with it or to persons handling
the same.
There are a number of surgical dressings or preparations, which contain various
salts of metals, such as for instance-saits of mercury, and it is an established
fact, that such preparations are being quickly decomposed when put up in such
compressible tubes (generally made of lead or analogous ductile metals, compo-

page_text: sitions, or alloys), and accordingly such dressings or preparations have to be pat
up in porcelain or glass jars or wooden boxes.
The object of this invention is to over-come the objection above referred to,
and to provide a compressible tube for the reception of surgical dressing, etc.,
and by the use of which the said surgical dressing cannot be effected or.
decomposed by the metal or alloy, of which the said tube is made.
The invention consists in the improved compressible tube, having its interior
wall or surface coated with a preparation indifferent to the action of the metal
or alloy of which the tube is made and also indifferent to the action of the pre-
paration or dressing contained in said tube, substantially as will be hereinafter
more fully described and finally embodied in the clauses of the claims.
For the above purpose the interior wall or surface of the tubes is coated with
collodion, to which has been added a small quantity of castor-oil and balsam fir.
The collodion is prepared by mixing ½ gallon of ether with ½ gallon of
alcohol, and adding 4 ounces of pyroxilin.
To one gallon of said collodion is added from two to three per cent. castor-cil
and from one to two per cent. balsam fir.
For the purpose of coating the tube, the same are slightly heated, and while
warm, are filled with the solution above referred to, which after remaining in
said tubes a short time, is poured out.
A certain amount of the solution adheres to the interior surface of the tubes,
and after the ether and alcohol has evaporated, forms a thin layer or coating,
which is impervious and indifferent to the action of the metal of which the tubes
are made and also indifferent to the various surgical dressings etc., placed in
said tubes..
It must also be remarked, that said thin layer or coating is ductile and will
not become detached from or blister off the tubes, while the latter are being
handled and compressed, and will not be effected by the temperature which is
used and is necessary for the sterilization of the dressing (together with the
tube).
For the purpose of completely expelling the air from the interior of the tube,
when the latter is being filled and the open end closed or folded, a small pin-
hole is provided for in the wall of the tube near its open end, and after said
open end is closed, that is to say, is compressed and folded together, the air
which still may have remained in the tube is discharged through said small pin-
hole, and the latter is then afterwards closed by the folded or compressed portion
of the tube.
I do not intend to limit myself to the coating solution above described, as
other solutions may be used advantageously to separate the dressing or prepara-
tion from their retaining tubes.
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: A compressible tube of ductile and impervious metal having its interior
wall coated with a solution or preparation indifferent to the dressing or ingre-
dients placed in said tube, substantially as set forth.
2: A compressible tube of impervious and ductile material having its interior
wall coated with a solution or preparation indifferent to the action of the dress-
ing or ingredients placed in said tube, and also indifferent to the temperature
necessary for sterilizing said dressing or ingredients together with the tube, sub-
stantially as set forth.
3: A compressible tube of ductile and impervious metal having its interior
surface or wall coated with a solution of collodion, castor-oil and balsam fir.
substantially as and for the purposes described.
4: A compressible tube of ductile and impervious metal having its interior
surface coated with a solution of collodion, castor-oil and balsam fir, and provided

page_text: near its inlet opening with a vent or pin-hole, substantially as and for the pur-
poses described.
5: A compressible tube, of ductile and impervious metal provided near its
inlet opening with a vent or pin-hole, substantially as and for the purposes
described.
