EMBALLAGE DE MATERIAU SOUPLE SOUS TUBE OVAL

PACKAGE OF FLEXIBLE MATERIAL WITH OVAL PAYOUT TUBE

Abrégé anglais

ABSTRACT OF THE DISCLOSURE
The invention relates to a package of material
wound in a series of figures-8s with the cross-overs advancing
around the package, and the cross-overs being omitted at at
least one point on the circumference of the package to leave
a radial hole into the center of the package for inner end
feedout to allow payout without twist. This hole is ordinarily
somewhat diamond shaped, with its major axis extending substant-
ially perpendicular to the axis about which the material was
wound. A payout tube is placed in that hole, this payout tube
having an oval shape.

Revendications

The embodiments of the invention in which an exclusive
property or privilege is claimed are defined as follows:
1. A package comprising a coil of flexible material
wound in plurality of layers of Figure-8 winds with the cross-
overs progressing around the package in each layer and having
a radial opening through the wall of the coil from the outside
to a central core space of the wound flexible material, said
radial opening having a greater length in the direction sub-
stantially perpendicular to the axis about which said material
was wound, and a payout tube passing through said radial opening
through which the inner end of the material is drawn out, said
payout tube being oval in cross-section with its major axis
extending parallelly to said perpendicular direction, the cross-
section of the material being less than the minor axis of said
payout tube.
2. A package as in claim 1 further comprising a
container enclosing said coil and having an opening in a wall
thereof, said last mentioned opening being aligned with said
radial opening and means securing said oval payout tube to
said wall of the container.

Description

BACKGROUND OF THE INVENTION
1. Field of the Invention _
The invention relates to a package of!flexible material
wouund in a series of figure-8s with a radial opening for inner
end feedout and a payout tube within the opening. ~ .
2. The Prior Art -
- The use of tubes in packages of this type is shown
... .. . .
or example in Gordon patent No. 3,677,490. Such tubes in the
past have always been round in cross-section.
SUMMARY OF THE INVENTION
According to the present in~ention, a payout tube is
., formed in an oval shape to it in the hole in the package, which
f when such a hole is formed by reversing the direction of the cross
; 25 overs in each of the winding layers ordinarily has a diamond shape

and is somewhat elongated in the direction perpendicular
to the axis about ~hich the material was wound. The use of -
an oval tube both fills the hole to a greater degree, thus
providing a greater amount of support for the material on
each side of the hsle, and at the same time allows some
freedom of movement of the wound material, assuming that its
diameter is less than the minor axis of the elliptical oval
payout tube, which allows it to shift from one side of the
tube to the other and improve the payout. This also permits
the size of the hole to be reduced somewhat for large materials
so that the amount of material in the coil can be increased.
Thus, in general terms, the present invention ~rovides
; a package comprising a coil of flexible material wound in
plurality of layers of Figure-8 winds with the cross-overs
lS progressing around the package in each layer and having a
radial opening through the wall of the coil from the outside
to a central core space of the wound flexible material, said -
radial opening having a greater length in the direction sub-
stantially perpendicular to the axis about which said material
was wound, and a payout tube passing through said radial opening
through which the inner end of the material is drawn out, said
payout tube being oval in cross-section with its major axis
ex~ending parallelly to said perpendicular direction, the cross-
section of the material being less than the minor axis of said
payout tube. The package may further comprise a container
enclosing said coil and having an opening in a wall
thereof, said last mentioned opening being aligned with sa-d
radial opening and means securing said oval payout tube to
said wall of the container.

BRIEF DESCRIPTION OF THE DRAWrNGS
Fig. 1 shows in cross-section a package for a coil
according to the invention;
Fig. 2 shows an end view of the tube;

invention combined with a package.
DESCRIPTION OF T~i P~;~ R~ EMBODIMENTS
The arrangement shown in the drawings is a package
comprising a container 2 in which is a coil 4 formed of flexible
material wound in a series of figure-8 coils with the cross-overs
progressing around the package, but interrupted at one point so
as to leave a radial hole from the outside into the central core
space of the wound material through which the inner end of the
material can be drawn out.

In practice, this radial hole will ordinarily be
longer in a direction perpendicular to the winding axis of
the material than in a direction parallel to such axis ordinar-
ily has a diamond shape.
The package container 2 has an opening 6 therein of
diamond shape conforming generally to the shape of the
opening in the coil. Within this there is arranged a tube
which extends from the outside into the interior of the pack-
age, for guiding the material out of the package.
The tube is oval in cross-section with its major
axis extending parallel to the major axis of the radial hole
of the coil. The main body of the tube is indicated at 8.
At its outer end it has a flange 10 which fits against the
side wall of the container, by which it may be secured in
position on the package, for example by an adhesive. The
free inner end 12 of the material is brought out through the
tube in a manner shown in Fig. 4. The diameter of the material
is less than the minor axis of the tube.
