‘Douglas Henderson, Toronto, Ontario, Canada
Application August 14, 1937, Serial No. 159,076
4, Claims.
(Cl. 221-430)
This invention relates to containers and par
ticularly to containers ‘of the collapsible tube type.
These containers have usually been made of tin,
aluminum, lead or metal and the top or discharge
5 end is usually formed integral with the body. The
body of the container is generally formed of quite
thin material to permit it being compressed and
rolled up to discharge the contents, and the nec
essary rigidity ‘is obtained by making the ‘dis
charge end or top quite thick. The outlet is
formed in the stiff top and provided with suitable
closure means, which may be of the screw cap,
automatic or other type.
These metals are comparatively expensive, and
further the metal does not lend itself readily to
coloring.
'
My object therefore is to devise a container in
which, when set, holds the blank in rolled form. I
This upper portion 2 is then bent inwardly as
shown in Fig. 3, to form an inwardly directed
?ange 3, the material being preferably pleated
or folded upon itself as shown to avoid slitting of
the ?ange. It will be evident, of course, that in
stead of rolling up the body from a ?at sheet.
in the manner described, the body with its inte
gral ?ange may betmoulded or otherwise formed
from paper stock.
‘
-
The head of the tube is formed of a main part
provided with an inclined shoulder portion 4 and
a central projection 5 through which latter the
outlet is formed. This main part is ?tted within
which paper or parchment or similar cheap ma‘

of the constructions hereinafter described and

of the body of less thickness than the main part
of the container body. Before rolling the material
is coated with a waterproof non-cracking glue

shown in Fig. 6.
_
In Fig. 7 a modi?cation is shown in which the
neck'portion ‘I of the'top has an annular pe
ripheral» recess in its under side to receive the
?ange on the body, and an annular member 8 is
forced into the recess to clamp the ?ange in

In the drawing like numerals of reference indi
cate corresponding parts in the di?erent ?gures.
A indicates the body of the container and B
40 the outlet end thereof. The body is formed of
paper, parchment or similar material, which may,
if desired, be treated with a suitable material to
render it moisture proof, as well as proof against
damage by the contents of the container. I ?nd,
45 however, that the paper known in the trade as
- “vegetable parchment." is satisfactory for a num
ber of purposes without further treatment.
In the preferred construction, the body is
formed from a ?at blank of material as shown
50 v in Fig. 1, which is rolled up to the tubular form as
shown in Fig. 2. It wil be noted that the blank
I is provided with an extension 2 along part of
one edge.

.
'
This results, when the body-ls rolled up, in the
55 forming of a narrow strip along the upper edge
.
- The lower end of the tube will be ?attened out
in the usual manner and held closed by means of
a clamping strip 9.
I
The body may be provided with a paint, enamel,
or other ?nish as desired, and may also have
printing or decorating matter applied thereto. If
desired, the printing may be applied to the body
before rolling takes place.
What I ‘claim as my invention is:
1. In a container, the combination of a tubu
lar body of paper or paper-like material, having 45
an annular inwardly directed ?ange at its outlet
end; and‘ a top of rigid material for said outlet
end, said ,top comprising separate inner and outer
members slidably movable relative to one another
in a direction longitudinally of the body and be 0
tween which the said ?ange is clamped, said mem
bers frlctionally_ engaging one another and nor
mally tending to resist separation, the exterior
diameter of the inner member being the same as
55
the interior diameter of the body.
