COMPLETE SPECIFICATION.
Improvements in Collapsible Tubes.
I, WILLIAM SOULE SCALES, of Everett, County of Middlesex, State of Massa-
chusetts, United States of America, Mechanic, 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 has for its object to improve the construction of collapsible
tubes, and it consists essentially in a collapsible tubular body, crimped at one
end to fold inward toward the middle of the tube, and a head comprising two
plates between which said crimped end of the tubular body is clamped. The
head will have an opening through it, as an outlet, which may be closed by a
cap or stopper. As a means of connecting said plates together to clamp the end
of the tubular body flanges may be formed on a neck which will receive said
plates between them, and said neck will have a hole through it which will serve
as an outlet for the tube.
Referring to the accompanying drawing,
Figure I shows in vertical section a sufficient portion of a collapsible tube
embodying this invention to illustrate the same, the parts being in assembled
position but not clamped together.
Figure 2, a similar vertical section showing the parts clamped together, and
Figures 3 and 4, details showing the crimped end portion of the tubular body.
The collapsible tubular body is herein composed of an inner tube a and an
outer tube b, said tubes being laid one upon the other, although so far as my
invention is concerned said tubular body may be composed of one or more tubes
as may be desired.
One end of the tubular body, whether composed of one or more tubes, is
crimped for a short distance, i.e. it may be first scored as at a and thereafter
pleated or folded to close inward and partially close the end of the tubular body,
and said pleated or folded end portion I herein call a crimped end.
In Figures 3 and 4 the end portion of the tubular body is shown as crimped. The
head is composed of two plates c and d, preferably made circular and of any
suitable size, and said plates are also preferably made of metal and dished, and
the crimped end portion of the tubular body is placed between said plates. c and d,
as represented in Figure 1.
A tubular neck e, preferably made of soft metal, is provided, which is inserted
through central holes formed in the plates c and d, and said neck e has formed
at its lower end a flange el upon which the bottom plate crests, and said neck o
is also provided with a shoulder e, which when compressed by suitable dies pro
vided for the purpose, will project laterally and form a flange which may be
pressed down on to or impinged upon the uppermost plate d of the pair of plates,
and thereby firmly and securely clamp and hold said pair of plates together, with
the crimped end portion of the tubular body between them. The collapsible
tubular body will thus be securely and tightly connected with the neck.
A closing cap f will be provided, which is herein shown as provided with an

page_text: internal screw-thread, which is turned on to a screw-threaded portion of the
neck e, although said closing cap f may be otherwise constructed, or a stopper
used as a means of closing the tube.
While I have herein shown the two plates c and d as clamped and held together
by flanges on the neck e I do not desire to thus limit my invention as said
plates may be otherwise connected or clamped together so as to firmly hold the
end portion of the tubular body between them.
The crimped end portion of the collapsible tubular body being composed of
the same material as said collapsible body will of course yield or collapse, not-
withstanding it is crimped, unless reinforced or stiffened, and it is desired that
the completed collapsible tube shall have a stiffened or unyielding head and con-
sequently the two plates c and d are made of metal and serve to reinforce or
stiffen the head of the tube in addition to serving as a clamp for engaging and
holding the upper end of the tubular body, and to furthermore ensure proper
rigidity for the head one of the two plates, preferably the bottom plate c, will be
made of a diameter approximately equal to the internal diameter of the tubular
body.
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. In a collapsible tube, a collapsible tubular body having a crimped end, a
head comprising two plates between which said crimped end is clamped, the
bottom plate being approximately the internal diameter of the tubular body and
a tubular neck having flanges for holding said plates securely together, sub-
stantially as described.
2. In a collapsible tube, a collapsible tubular body, and a head comprising
two dished plates between which one end of said tubular body is clamped, one
of said plates being approximately the internal diameter of the said tubular
body, and a tubular neck having flanges which impinge upon and thereby hold
said plates securely together, substantially as described.
3. In a collapsible tube, a collapsible tubular body, and a head comprising
two dished plates between which one end of said tubular body is clamped, and
a tubular neck having a flange el and a compressible shoulder which constitute
means for securing said neck to the plates and also means for holding said plates.
together to clamp and hold the tubular body, substantially as described.
4. In a collapsible tube, a collapsible tubular body having a crimped end, and
a head comprising two plates between which said crimped end of the tubular
body is clamped, the bottom plate being approximately the internal diameter of
said tubular body, substantially as described.
5. In a collapsible tube, a crimped top collapsible tubular body, a head com-
prising two plates between which said crimped top is clamped which serves also
to reinforce and stiffen said crimped top, to provide an unyielding head for the
tube, a tubular neck and means for connecting said neck to the plates which also
holds said plates securely together, substantially as described.
6. In a collapsible tube, a crimped top collapsible tubular body composed of
two layers of material laid one upon the other, both layers being crimped, a
head comprising two plates between which said crimped end portion of the body,
is clamped, and a tubular neck having flanges for securing said neck to the
plates and also for holding said plates securely together to clamp the crimped
top of the tube, substantially as described.
