Improvements in Compressible Tubes.
We, 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, and ALFRED
GARTNER, of No. 152, Market Street, in the City of Paterson, County of Passaic,
and State of New Jersey, U.S.A., Civil Engineer, do hereby declare the nature
of this invention to be as follows:-
Our present invention relates to improvements in compressible tubes or
receptacles made of impervious, ductile material, and which are generally used
for paints, dentifrices, surgical dressings etc.
Said tubes are usually provided with small discharge outlets adapted to be
closed by screw-threaded caps, and have their opposite ends folded and pressed
together; whenever the contents of said tubes are to be discharged (after the
Screw-threaded caps have been removed), the opposite or folded ends are
compressed.
It is an established fact, that by so compressing the folded ends of the tubes,
it is difficult to discharge the entire contents, as a certain amount of said contents
does naturally during the compressing-re-enter the folded or previously com-
pressed portions of the tubes, which--besides rendering such tubes uneconomical-
in great many cases--is the cause of bursting said tubes, or of discharging the
contents through the folded ends.
In cases where the tubes are filled with surgical dressing which readily
decomposes, said re-entering of the dressing into the compressed or folded portions
of the tubes as experience has proven-greatly aids the decomposing of the
contents.
The object of our invention is to provide tubes of the character above referred
to with means, whereby the contents of said tubes can be conveniently and
uniformly discharged, and furthermore--by which means the re-entering of the
contents into the once compressed or folded portions of the tubes is fully avoided.
The invention consists in the improved compressible tube combining a key or
clamp for closing and folding the flattened end of said tube, substantially as will
be hereinafter more fully described.
Referring to the accompanying drawing, in which like letters of reference
indicate corresponding parts in each of the several views: Fig. 1, is a front

Fig. 5 consists of a round piece of wire h, having one end turned at right-angles
as at, and penetrated by an elongated slot m, of dimensions substantially equal
to the dimensions of the compressed or folded end d of the tube.
It must be remarked, that the side portions of the key constituting the slot are
pressed or clamped upon the folded or compressed end of the tube, whereby a
perfect air tight joint is obtained.
To prevent a reopening of said folded end of the tube, the key is burned once
or twice around together wi h said folded end, as clearly illustrated in the sectional
view of Fig. 3.
When it is desired to discharge a portion of the contents of the tube, the screw
threaded cap is removed, and the key is turned or rotated, by which operation the
portion of the tube adjacent to the key gradually becomes flattened, and is coiled
around said key, as will be manifest.
By this operation it is impossible for the contents of the tube to re-enter the
once folded or compressed portion.

Improvements in Compressible Tubes.
We, 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, and ALFRED
GARTNER, of No. 152, Market Street, in said City of Paterson, County of Passaic,
and State of New Jersey, U.S.A., Civil Engineer, 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:-
Our present invention relates to improvements in compressible tubes or
receptacles made of impervious, ductile material, and which are generally used
for paints, dentifrices, surgical dressings etc.
Said tubes are usually provided with small discharge outlets adapted to be
closed by screw-threaded caps, and have their opposite ends folded and pressed
together; whenever the contents of said tubes are to be discharged (after the
Ascrew-threaded caps have been removed), the opposite or folded ends are
compressed.
It is an established fact, that by so compressing the folded ends of the tubes,
it is difficult to discharge the entire contents, as a certain amount of said contents
does naturally during the compressing-re-enter the folded or previously com-
pressed portions of the tubes, which-besides rendering such tubes uneconomical-
in great many cases-is the cause of bursting said tubes, or of discharging the
contents through the folded ends.
In cases where the tubes are filled with surgical dressing which readily
decomposes, said re-entering of the dressing into the compressed or folded portions

page_text: of the tubes as experience has proven-greatly aids the decomposing of the
contents.
The object of our invention is to provide tubes of the character above referred
to with means, whereby the contents of said tubes can be conveniently and
uniformly discharged, and furthermore-by which means the re-entering of the
contents into the once compressed or folded portions of the tubes is fully avoided.
The invention consists in the improved compressible tube combining a key or
clamp for closing and folding the flattened end of said tube, substantially as will
be hereinafter more fully described and finally embodied in the clauses of the
claims.
Referring to the drawings filed with the Provisional, in which like letters of
reference indicate corresponding parts in each of the several views: Fig. 1
is a front elevation of a compressible tube provided with our improvements;
Fig. 2 an end elevation of Fig. 1--the screw-threaded cap being removed;
Fig. 3 an enlarged detail sectional view on the line of the lower portion of
Fig. 1; Fig. 4 an enlarged detail perspective view of the key or clamp used in
connection with the tube; and Fig. 5 a perspective view showing a modified form
of the key or clamp.
In said drawings, a represents a cylindrical tube or receptacle, made of
impervious, ductile material and provided at one end with a small discharge
outlet b, adapted to be engaged by a screw-threaded cap c, of the usual and well
known construction.
The opposite end of said cylindrical tube or receptacle is pressed together or
flattened as at d, Fig. 3, and is clamped within an elongated slot e of a key fi
which latter is provided at one end (or both ends) with an arm or handle g-as
in Fig. 4.
The key illustrated in the last mentioned figure is stamped out of sheet metal
and is afterwards bent to form said elongated slot e, whilst the key shown in
Fig. 5 consists of a round piece of wire h, having one end turned at right-angles
as at i, and penetrated by an elongated slot m, of dimensions substantially equal
to the dimensions of the compressed or folded end d of the tube.
It must be remarked, that the side portions of the key constituting the slot are
pressed or clamped upon the folded or compressed end of the tube, whereby a
perfect air tight joint is obtained.
To prevent a reopening of said folded end of the tube, the key is turned once
or twice around together with said folded end, as clearly illustrated in the sectional
view of Fig. 3.
When it is desired to discharge a portion of the contents of the tube, the screw
threaded cap is removed, and the key is turned or rotated, by which operation the
portion of the tube adjacent to the key gradually becomes flattened, and is coiled
around said key, as will be manifest.
By this operation it is impossible for the contents of the tube to re-enter the
once folded or compressed portion.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim, is:
1: A compressible tube having one of its ends flattened or pressed together,
and a key or clamp carried by said flattened end, substantially as and for the
purposes described.
2: A compressible tube having one of its ends flattened or pressed together,
and a key or clamp surrounding said flattened end and engaging the same, sub-
stantially as and for the purposes described.
3: A compressible tube having one of its ends flattened or pressed together;
and a key or clamp provided with an elongated slot mounted upon said flattened
end, substantially as and for the purposes described.
4: A compressible tube having one of its ends flattened or pressed together

page_text: and folded upon itself, and a key or clamp mounted upon the extreme end of said
flattened portion, substantially as and for the purposes described.
5: A compressible tube having one of its ends flattened or pressed together and
folded upon itself, and a key or clamp provided with an elongated slot mounted
upon the extreme end of said flattened portion, substantially as and for the
purposes described.
6: A compressible tube having one of its ends flattened or pressed together, a
key or clamp mounted upon said flattened end, and a suitable handle on one or
both ends of said key, substantially as and for the purposes described.
7: A compressible tube having one of its ends flattened or pressed together
and folded upon itself, a key or clamp mounted upon the extreme end of said
flattened portion, and a suitable handle on one or both ends of said key, sub-
stantially as and for the purposes described.
8: A compressible tube provided at one end with a removable cap and having
its opposite end flattened or pressed together, and a key or clamp mounted upon
said flattened end, substantially as and for the purposes described.
9: A compressible tube provided at one end with a removable cap and having
its other end flattened or pressed together and folded upon itself, and a key or
clamp mounted upon the extreme end of said flattened portion, substantially as
and for the purposes described.
10: A compressible tube provided on end end with a removable cap and having
its opposite end flattened or pressed together, a key or clamp mounted upon said
flattened end, and a suitable handle on one or both ends of said key, substantially
as and for the purposes described.
