PROVISIONAL SPECIFICATION.
Improvements in or connected with Collapsible Tubes for Holding
Liquid or Paste Paints, India Rubber Solution, Medical Ointments,
Perfumeries and similar Liquid or Plastic Substances.
I, DAVID STORER, Manufacturer, of Conduit Villa, Hyde Vale, Greenwich, in
the County of London, do hereby declare the nature of this invention to be as
follows:-
This invention. for improvements in or connected with collapsible tubes for
holding liquid or paste paints, india rubber solution, medical ointments, per-
fumeries and similar liquid or plastic substances, has for its object to provide a
ready means whereby the contents of the tubes can be readily expelled without
waste and with cleanliness and which shall ensure that practically the whole of
the contents shall be utilised; and consists in providing means whereby the tube
can be wound up tight from the bottom end.
In one way of carrying out this invention when folding up the bottom end of
the tube for the purpose of closing it after it has been filled, a narrow strip
of metal having a projecting head is inserted in one of the folds. When desired
to remove any of the contents instead of squeezing the tube in the usual manner,
the projecting head is turned in the direction to continue the folding up of the
end of the tube sufficiently to expel the required amount of substance.
In another way of carrying out this invention, a detachable key U-shaped in
cross section is employed. The free ends of the U are preferably turned inwards.
In use the key is slipped over the folded end of the tube and can be used for wind-
ing up the tube as above described. When the tube is empty the key is removed
and can be used in a similar way for another tube.

I, DAVID STORER, Manufacturer, of Conduit Villa, Hyde Vale, Greenwich, in
the County of London, do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-

ready means whereby the contents of the tubes can be readily expelled without

the contents shall be utilised; and consists in providing means whereby the tube
can be wound up tight from the bottom end.
In one way of carrying out this invention when folding up the bottom end of
the tube for the purpose of closing it after it has been filled, a narrow strip
of metal having a projecting head is inserted, in one of the folds. When desired
to remove any of the contents instead of squeezing the tube in the usual manner,
the projecting head is turned in the direction to continue the folding up of the
end of the tube sufficiently to expel the required amount of substance.
In another way of carrying out this invention, a detachable key U-shaped in
cross section is employed. The free ends of the U are preferably turned inwards.
In use the key is slipped over the folded end of the tube and can be used for wind-
ing up the tube as above described. When the tube is empty the key is removed
and can be used in a similar way for another tube.
In the accompanying sheet of illustrative drawings: Fig. 1 is a sectional side
elevation of a collapsible tube provided with a fixed handle or key for winding up
the tube from the bottom to expel the contents and Fig. 2 is a front elevation of
the same.
Figs. 3 and 4 are similar views to Figs. 1 and 2 showing a removable handle
that can be readily removed from one tube and applied to another. Fig. 5 is a
plan thereof.
In Figs. 1 and 2, the handle consists of the shank a and the head b. The
shank a is inserted in the folds c that close the bottom of the collapsible tube d,
the shank being inserted whilst the tube is being closed. To expel the contents
the head b is turned in the direction to continue the folding up of the tube.
Figs. 3 and 4 show a removable key e formed from a bent piece of wire. The
closed folded up end f of the collapsible tube is inserted between the prongs g
of the key e This key can be removed and applied to another tube. The prongs
are preferably made so that they tend to approach one another by their elasticity
so that they grip the end of the tube tightly.
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 collapsible tube provided with means for winding up the tube from the
bottom to expel the contents.
2. An improved means for winding up collapsible tubes for the bottom to expel
their contents substantially as described with reference to the drawings.
