Improvements in Collapsible Tubes or Receptacles for Holding
Semi-fluid Substances.
I, MARTIN PERLS, of 100, Brondesbury Villas, Kilburn, in the County of
Middlesex, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the collapsible tubes ordinarily used for containing
paint or other semi-fluid substances.
Such tubes have ordinarily heretofore been made of soft metal, having a small
opening closed by a screw cap at one end, the contents being introduced at
the other end, which is then closed down.
Such tubes, however, are heavy, they readily get out of shape, and the metal
of which they are made is liable to communicate an unpleasant odour to the
contents, or in some cases, to act injuriously upon such contents, and my present
invention has for its object a novel method of making collapsible tubes of a
material which has no injurious action upon their contents, so that delicate
mixtures, such as scented shaving soap cream, scented cosmetics, and the like,
may be kept in them without injury or deterioration.
«
For this purpose, I make the tubes of the materials well known as celluloid,"
xylonite," or others of a similar description, more or less transparent, which
are sufficiently flexible to be readily used for the purpose required, and are
inexpensive, and absolutely inert and without objectionable effect upon the most
delicate scented or other substances contained in tubes made of them.
I make the collapsible tubes of celluloid or the like, either made in the form
of tubes of the required size, and thickness, or from a sheet of celluloid bent
into the required shape and cemented or otherwise fixed.
The upper end or mouth of the tube may be of celluloid forming part of the
tube itself, and made of the proper shape and size, with a small opening through
it for discharging its contents, and a screwed mouth upon or into which a cap
or stopper can be fitted. Or, the upper end may be formed separately of celluloid,
and be fitted and cemented or otherwise fixed in the open end of the tube. Or,
it may be made of any other suitable material, such as glass, earthenware, wood,
or metal, cemented or otherwise fixed into the open upper end of the tube.
Collapsible tubes made according to my invention are very durable, have a
sufficiently attractive outward appearance so that they need not be pasted over
with paper as metal tubes generally are, whilst, being more or less transparent,
the celluloid tube which forms the body of the receptacle can be made to allow
the contents to be visible.

substances with which they may be filled.

Improvements in Collapsible Tubes or Receptacles for Holding
Semi-fluid Substances.
I, MARTIN PERLS, of 100, Brondesbury Villas, Kilburn, in the County of
Middlesex, Manufacturer, 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, that is to say: -
My invention relates to the collapsible tubes ordinarily used for containing
paint or other semi-fluid substances."
Such tubes have ordinarily heretofore been made of soft metal, having a small
opening closed by a screw cap at one end, the contents being introduced at
the other end, which is then closed down.
Such tubes, however, are heavy, they readily get out of shape, and the metal
of which they are made is liable to communicate an unpleasant odour to the
contents, or in some cases, to act injuriously upon such contents, and my present
invention has for its object a novel method of making collapsible tubes of a
material which has no injurious action upon their contents, so that delicate
mixtures, such as scented shaving soap cream, scented cosmetics, and the like,
may be kept in them without injury or deterioration.
For this purpose, I make the tubes of the materials well known as "celluloid,"
"xylonite," or others of a similar description, which are more or less transparent,
and sufficiently flexible to be readily used for the purpose required, and are
inexpensive, and absolutely inert and without objectionable effect upon the most
delicate scented or other substances contained in tubes made of them.
I make the collapsible tubes of celluloid or the like material as described,
either in the form of tubes of the required size, and thickness, or from a sheet
of celluloid bent into the required shape and cemented or otherwise fixed.
The upper end or mouth of the tube may be of celluloid forming part of the
tube itself, and made of the proper shape and size, with a small opening through
it for discharging its contents, and a screwed mouth upon or into which a cap
or stopper can be fitted. Or, the upper end may be formed separately of celluloid,
and be fitted and cemented or otherwise fixed in the open end of the tube. Or,
the upper end may be made of any other suitable material, such as glass, earthenware,
wood, or metal, cemented or otherwise fixed into the open upper end of the tube.
The lower ends of the tubes, after filling, may be closed in any convenient way; as,
for instance, by squeezing or flattening together the sides of the end of the tube,
and doubling over once or more the flattened end. Or, the sides of the end of
the tube may be flattened together in the way just described, being held together
by a suitable cement. I do not, however, confine myself to any particular method
of closing the end of the tube.
Collapsible tubes made according to my invention are very durable, have a
sufficiently attractive outward appearance so that they need not be pasted over
with paper as is usually the case with the metal tubes ordinarily used, whilst

page_text: being more or less transparent, the celluloid tube which forms the body of the
receptacle can be made to allow the contents to be visible.
They are inexpensive to make, and can be made in no way injurious to the
most delicate substances with which they may be filled.
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:-
Making collapsible tubes or receptacles for holding semi-fluid substances, of
more or less transparent and flexible celluloid, xylonite, or the like material,
substantially as described.
