DISPENSER CONTAINER HAVING A TEAR-OUT SIGHT GAUGE
Abstract
A container of the class wherein fluent materials such as
chemicals are packaged in transparent or translucent plastic bags
encased in a relatively rigid rectangular paperboard container for
shipping and dispensing purposes. For dispensing purposes the
container is inverted and a retractable spout on the plastic bag is
pulled through an opening provided in the flap-closed end, or top,
of the paperboard container. To permit the fill level of the
contents to be followed the side wall of the container is provided
with a tear-out sight gauge. In the preferred embodiment this
tear-out sight gauge is combined with a tear-out opening in the top
of the container through which the spout of the plastic bag is
pulled for dispensing purposes so that the container can be opened
and provided with a sight gauge in one tearing operation.

Description
This invention relates to improvements in containers of the class
wherein fluent materials such as chemicals are packaged in liner
bags composed of transparent or translucent plastic material, and
the substantially filled bag is encased in a relatively rigid
rectangular paperboard container for shipping and dispensing
purposes.
Containers of this type are generally well-known and for dispensing
purposes the container is inverted and a retractable spout on the
plastic bag is pulled through an opening provided in the
flap-closed end, or top, of the paperboard container. Up to the
present time, such containers have not been provided with a sight
gauge through which the fill level of the contents can be viewed.
Accordingly, such known containers are not suitable for use in
automatic or semi-automatic replenishment systems where it is
necessary for the user to be able to replace one container with
another at the time or before the first becomes completely
empty.
The primary object of the present invention is to provide a
dispenser container of the above mentioned type having a tear-out
sight gauge for visually checking the fill level of the liner
plastic bag.
A further object is to provide a dispenser container of the above
mentioned type in which the top of the outer container is provided
with a tear-out opening through which the pouring spout of the bag
extends for dispensing purposes and which spout opening and sight
gauge are so arranged as to be formed by a single tearing
operation.
The novel features that I consider characteristic of my invention
are set forth with particularity in the appended claims. The
invention itself, however, both as to its organization and its
methods of operation, together with additional objects and
advantages thereof, will best be understood from the following
description when read in connection with the accompanying drawing
in which:
FIG. 1 is a perspective view of a dispensing container constructed
in accordance with a preferred embodiment of the present invention
inverted to the position in which it is used for dispensing
purposes and with the container opened for use;
FIG. 2 is a perspective view of the outer paperboard container
opened at the top for receiving a plastic bag filled with a fluent
material;
FIG. 3 is a plan view of the paperboard blank from which the
container shown in FIG. 2 is formed up; and
FIG. 4 is a plan view of an inner liner for the outer container to
give the same added rigidity.
Referring first to FIG. 1, the complete container includes a bottle
or bag 10 made of a suitable flexible plastic material, e.g.
polyethylene, which is inert to the fluent material with which it
is to be filled. Such bottles, commonly referred to by the
tradename "Cubitainer," have a pouring spout 11 which, when the
container is upright, is folded down inside of the outer case 12 in
which the bottle or bag is encased for shipping and handling
purposes. The outer case 12 is made of a heavy paperboard, e.g.
corrugated board, and is generally rectangular in shape and has a
top 13 provided with a tear out opening 14 through which the spout
of the bag may be extended, as shown, for dispensing purposes.
Contiguous with the opening 14 in the top of the container, there
is a sight gauge opening 15 which extends up the side wall of the
container and through which one can view the fill level of the
plastic bag or bottle. The opening 14 in the top of the container
and the sight gauge opening 15 in the side wall thereof originally
exist only as a weakened tear out section until the container is
opened for use so that the plastic bag or bottle is completely
protected during shipment and handling prior to use. When in use,
the container is supported on a rack or other support, not shown,
in the inverted position shown in FIG. 1, the outer case or
container 12 being sufficiently rigid to prevent the plastic bag
from being deformed due to its weight.
In FIGS. 2 and 3 the blank from which the container is formed, and
the formed-up container open for receiving a plastic bag or bottle
10, are shown. The blank 16 from which the container 12 is formed
is died out of a heavy paperboard, e.g. corrugated board, and
includes four panels 17, 18, 19 and 20 which when folded along fold
lines 21, 22 and 23 form the side walls of the container. A narrow
flap 24 separated from panel 20 by a fold line 25 folds in against
the inside face of panel 17 and has an adhesive applied thereto to
hold the panels in an erected condition. The bottom of the
container is formed by folding in four flaps 26, 27, 28 and 29
along fold lines 30, 31, 32 and 33 and cementing them in superposed
relation.
Connected to the top edge of panels 18 and 20 by fold lines 34 and
35 are top flaps 36 and 37, respectively, which extend the full
width of the container and are therefore referred to as full flaps.
Each of these two full flaps is provided with a circular opening 38
and 38' so arranged in their respective flaps that after the blank
is formed up to the shape shown in FIG. 2 and these flaps are
folded down on top of one another to close the container the two
openings 38 and 38' come into alignment to allow the spout of the
plastic bag 10 to extend therethrough.
Connected to the top edge of panels 17 and 19 by fold lines 40 and
41 are half flaps 42 and 43, respectively, so called because they
are only half as wide as the box and meet in the middle thereof
when they are folded in on top of the container. Half flap 43 and
panel 19 have a removable section 44 circumscribed by a contiguous
weakened line 45 which may consist of a series of serrations or
slits which do not penetrate through the thickness of the
paperboard. When the half flap 43 is folded in on top of the full
flaps, the enlarged portion of the removable section 44 aligns with
the openings 38 and 38' in the full flaps 36 and 37. To facilitate
removal of removable section 44 when the container is to be opened
for use, a portion of the weakened line 45, preferably the arcuate
end lying in side panel 19, is cut completely through the thickness
of the board. This allows this end of the removable section 44 to
be pressed inwardly, since there is nothing behind it but the
flexible plastic bottle, to form a tab which can be grasped and
pulled outwardly to remove the removable section 44 in one
continuous tearing operation. In this manner the top of the
container is provided with an opening through which the spout on
the plastic bag or bottle can be pulled for dispensing purposes and
the side wall formed by panel 19 is provided with the tear-out
sight gauge 15 in one tearing operation.
After the paperboard blank 16 is formed up into an open-ended box
as shown in FIG. 2, a filled plastic bag or bottle 10 is dropped
into the open end thereof and the spout is folded in or retracted
below the top edges of the side walls. Full flaps 36 and 37 are
then folded down into superposed relation in either order to close
the end of the box and finally the half flaps 42 and 43 are folded
down on top of the full flaps. The container can be sealed shut by
applying adhesive to the underside of half flaps 42 and 43 or by
applying a strip of adhesive tape over the abutting ends of the
half flaps and down over the side walls 18 and 20 of the container.
When the container is thus closed, the plastic bag or bottle within
it is completely covered and well protected for shipment. To ready
the container for use, it is only necessary to press in on the
arcuate end of the sight gauge portion of the removable section 44
to form a tab which can be grasped and pulled upwardly to remove
the section 44 in one tearing operation. Removal of section 44
provides an opening aligned with circular openings 38 and 38'
through which the spout of the plastic bag or bottle may be grasped
and pulled out to ready the container for dispensing purposes and
at the same time provides a sight gauge in the side wall at the end
of the container through which the spout extends and through which
one can watch the fill level of the inner container or bag.
Should it be found necessary to increase the rigidity of the side
walls of the container over that which can be obtained with a
single thickness of paperboard which can be readily handled, this
can be done by the use of an inner liner formed from a paperboard
blank of the type shown in FIG. 4. For use in a square container as
shown, this inner liner comprises a blank 50 of paperboard having
four equal sized panels 51, 52, 53 and 54 having a depth and width
equal to the inside dimensions of the side walls of the container
formed from blank 16. When these panels 51-54 are folded inwardly
along fold lines 55, 56 and 57 separating them, a square sleeve is
formed which will slide down inside of the container formed up from
blank 16. The panel 53 of the inner liner has an arcuate-ended
elongated notch 60 extending in from one free edge thereof, which
notch has a shape and size corresponding to the sight guage opening
15 in the side wall of the container formed by panel 19. The inner
liner 50 will be slipped into the open-ended container shown in
FIG. 2 before the filled plastic bag 10 is put therein and the
packer must make sure that the liner is oriented in the container
so that the notch 60 aligns with the sight gauge portion 15 of the
removable section 44 otherwise the sight gauge opening when torn
out will open onto a wall of the inner liner and be useless.
While in the embodiment of the container shown and described four
flaps, two full and two half, have been used to close the open end
thereof, the present invention is not limited to such a
construction. For example, instead of using four flaps as
described, three full flaps could be foldably connected to the top
edge of three side walls. Two of these flaps which are to be folded
in first would have the circular openings 38 and 38' which would
come into alignment and the third flap and the side wall to which
it is hinged would have the removable section 44 formed therein,
the enlarged portion thereof being arranged to align with the
circular openings in the other two flaps. The uppermost full flap
could then be sealed to the full flap immediately beneath it to
seal the container closed, or the uppermost flap could be sealed
down by a strip of adhesive tape connecting it to one or more of
the side walls of the container. It will be readily appreciated
that the container need not be square as shown and described, but
could be rectangular or of other suitable polygonal shape as its
use might dictate.
This invention has been described with reference to particular
embodiments thereof, but it will be understood that variations and
modifications may be effected within the spirit and scope of the
invention.
