PROVISIONAL SPECIFICATION.
Improvements in Flexible Metal Tubes for containing Liquids or
Semi-liquids.
We, BETTS AND COMPANY LIMITED, of No. 1, Wharf Road, City Road, in the
County of London, and WILLIAM NIMMY, of 4, Oakley Road, Southgate Road,
Islington, in the said County, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to tubes which are made of flexible metal such as tin
or lead, for containing liquids or semi-liquids which are expelled through an
orifice at one end by pressure applied to the tube. In such tubes as hitherto
made the orifice has been made through a screwed nipple piece at one end and
the said orifice has been closed by a loose screw cap. A great objection to this
is that the cap is readily lost and the contents of the tube therefor are liable to
become deteriorated.
It is the object of this invention to overcome this objection which is effected
with
by providing the screwed nipple piece with a flange, or stop and the cap
a turned-in part or counterstop so that when the cap is unscrewed the said stops
prevent the cap being entirely removed and retain it in place on the nipple
piece. A perforation is made in the cap so that the liquid or semi-liquid which
is forced from the tube passes through the orifice both in the nipple picce and
in the cap.
The closure of the orifices in the nipple piece and cap may be effected either
by making the said orifices so that they are not in line with each other or a
disc or valve may be provided in the space between the nipple piece and cap to
be pressed down and close the orifices when the cap is screwed down.

page_text: 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 relates to tubes which are made of flexible metal, such as tin
or lead for containing liquids or semi-liquids which are expelled through an
orifice at one end by pressure applied to the tube. In such tubes, as hitherto
made, the orifice has been made through a screwed nipple piece at one end and
the said orifice has been closed-by a loose screw cap. A great objection to this,
is that the cap is readily lost and the contents of the tube therefore are liable to
become deteriorated.
It is the object of this invention to overcome this objection which is effected
by providing the screwed nipple piece with a flange or stop, and the cap with
a turned-in part or counter-stop, so that when the cap is unscrewed, the said stops
prevent the cap being entirely removed and retain it in place on the nipple
piece. A perforation is made in the cap so that the liquid or semi-liquid which
is forced from the tube passes through the orifice both in the nipple piece and
in the cap.

In the accompanying drawing, we have illustrated in section manners
which this invention can be carried out in practice. In all the figures the tube
is marked a, and the nipple piece is marked it is provided with a neck at c
forming a stop at d. The cap is marked c. It is perforated at f and has a
turned in part at g, which engages in the neck c, which is of such a length as
to allow the cap to be unscrewed sufficiently to allow the contents to exude when
the tube. is pressed. In Figures 1 and 2 the closure of the orifices in the nipple
piece and cap is shewn as being effected by making the said orifices, so that
they are not in line with each other, when the cap is screwed down the metal
around the orifice in the nipple closes the orifice in the cap and when the cap
is unserewed the contents can be pressed out. Figures 3 and 4 shew a 'disc or
valve provided in the space between the nipple piece and cap, which disc or
valve is pressed down and closes the orifices when the cap is screwed down.
When the cap is screwed to open the orifice to discharge the contents the pro-
jections prevent the disc or valve h being pressed against the orifice f in
the cap to close it. Figures 1 and 3 shew the orifices closed and Figures 2
and 4 shew them open.
Having now particularly described and ascertained the nature of this in-
vention and in what manner the same is to be performed, we declare that what
we claim is :-
-
1. Flexible metal tubes, having formed therewith a nipple-piece and pro-
vided with a cap, the nipple piece and cap having stops for preventing the
entire removal of the cap and there being orifices in the cap and nipple-piece
the communication between which is closed when the cap is screwed down, sub-
stantially as hereinbefore described.
2. Flexible metal tubes formed with means for closing and opening them and
for preventing the cap being entirely removed as illustrated in and described
with reference. to the accompanying drawings.
