CONTAINER HANDLE
Abstract
A container handle is punched or cut from a flat sheet of
polyethylene so as to have a ring portion with a substantially oval
opening therein. The oval opening has a major axis and a minor axis
and the arms of a bail are integrally formed with the ring portion.
The arms are connected with the ring portion in areas adjacent
points where the major axis of the oval opening intersects the ring
portion. The ring portion is deformable to change the oval opening
into a substantially circular shape. Under this deformation, the
ring portion adjacent the intersection of the major axis curves
upwardly so as to slope downwardly on opposite sides of the major
axis. The arms of the bail are connected with the ring portion at
one of the downward sloping areas so that the bail is biased
downwardly to tightly hug a jar or bottle on which the container
handle is fitted.

Description
BACKGROUND OF THE INVENTION
This application pertains to the art of container handles and more
particularly to flexible plastic handles which are applied to the
neck of a jar or bottle. Previous handles of the flexible plastic
type have been molded. With molded handles, it is possible to
preform the handle bail so that it normally extends downwardly from
a ring portion to closely hug the neck of a bottle. With bails
which extend outwardly from a container on which the handle is
used, the bail interferes with compact storage of the containers
and is sometimes accidentally snagged by a person's fingers and the
container is overturned. Necessary molds for making container
handles with a bail which will extend downwardly and tightly hug
the exterior surface of a container are very expensive and
complicated to make. In addition, molding of container handles is a
very expensive and time consuming operation, and expensive
equipment is required for mass production.
SUMMARY OF THE INVENTION
In accordance with the present invention, a flexible plastic
container handle is formed by cutting or punching it from a flat
sheet of plastic. In accordance with the invention, the container
handle is punched or cut to a unique shape so that when it is
applied to the neck of a bottle or jar the handle bail will be
biased downwardly to tightly hug the surface of the bottle or jar.
The handle of the present invention includes a ring portion having
a substantially oval opening therein. The ring portion has flat
opposite faces and a width which is many times greater than its
thickness. The ring portion also has an outer peripheral edge and
an inner peripheral edge defined by the periphery of the oval
opening. The oval opening has a minor axis and a major axis, with
the major axis intersecting the ring portion at major axis
intersection points. A bail having a pair of spaced-apart arms and
a finger grip portion is integrally formed with the ring portion
and the arms are connected with the ring portion adjacent the major
axis intersection points. When originally formed, the ring portion
and the bail lie in a common plane. When the handle of the present
invention is applied to the neck of a bottle or jar, the ring
portion is deformable so that those portions of the ring which are
on opposite sides of the major axis of the oval opening will lie on
the surface of a cone with their inner peripheral edges facing
upwardly. Under such deformation, the ring portion curves upwardly
adjacent the major axis intersection points so as to provide
downward sloping portions extending from the major axis
intersection points toward the conical arcuate portions. The arms
of the bail are connected with the ring portion at a downward
sloping area so that the downward slope is imparted to the entire
bail and causes the bail to tightly hug the surface of a bottle or
jar on which the handle is fitted.
It is a principal object of the present invention to provide a
flexible plastic container handle which is economical to
manufacture and simple to apply to the neck of a bottle or jar.
It is a further object of the present invention to provide such a
container handle with a bail connected in such a manner that it
will be biased downwardly against the surface of a bottle or jar on
which the handle is fitted.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, wherein the showings are for
purposes of illustrating a preferred embodiment of the invention
only and not for purposes of limiting same, FIG. 1 shows an
integral one-piece container handle constructed in accordance with
the present invention. In accordance with the invention, a flat
sheet of polyethylene plastic is punched or cut to provide a single
piece of plastic having the exterior peripheral shape shown in FIG.
1. In addition, this piece of plastic is punched or cut to 20
openings 12 and 14 shaped as shown in FIG. 1. With this punching or
cutting, it will readily be recognized that a container handle is
formed with a ring portion A and bail B. Ring portion A and bail B
will lie in a common plane because they have been punched or cut
from a flat sheet of plastic material. In accordance with one
arrangement, the sheet of plastic from which the handle is punched
or cut may be 0.06-inch thick while ring portion A has a width of
around 0.50 inch.
In accordance with the invention, opening 14 is substantially oval
shaped, and includes a major axis 16 and a minor axis 18. It will
be recognized that the periphery of oval opening 14 defines an
inner peripheral edge for ring portion A. Ring portion A also has
an outer peripheral edge which is interrupted only by the points of
connection between ring portion A and bail B. Major axis 16 of oval
opening 14 intersects ring portion A at major axis intersecting
points or lines 20 and 22. Ring portion A then has arcuate portions
24 and 26 lying on opposite sides of major axis 16.
In accordance with the preferred arrangement, bail B includes a
pair of spaced-apart arms 28 and 30 which are integrally connected
by a finger grip portion 32. Arms 28 and 30 of bail B are
integrally formed or connected with ring portion A adjacent the
major axis intersection points 20 and 22. Connecting areas as at 34
and 36 connect ring portion A with arms 30 over areas lying on the
same side of major axis 16 as finger grip portion 32 of bail B.
Arcuate portions 24 and 26 include arcuate inner edges 38 and 40
defined by portions of the periphery of oval opening 14. As shown
in FIG. 1, arms 28 and 30 of bail B slope toward one another from
their points of connection to ring portion A and finger grip
portion 32 of bail B has a length which is less than the width of
ring portion A across major axis 16. With this arrangement, bail B
will not project outwardly from the sides of a cylindrical bottle
or jar as is the case when bails are formed with substantially
parallel arms.
In accordance with the invention, a conventional bottle or jar C
includes a neck portion 42 having an outwardly projecting bumper
roll 44 thereon. Jar C may be provided with threads 46 for
receiving a cover or the like although it will be appreciated that
the handle of the present invention is also usable with jars or
bottles which do not have threaded covers. In accordance with the
invention, the container handle is positioned above neck 42 of jar
C with oval opening 14 substantially axially aligned with the top
opening of jar C. Arcuate portions 24 and 26 may then be grasped
adjacent the intersection of minor axis 18 therewith and pulled
away from one another. This action deforms ring portion A so that
oval opening 14 takes on a circular shape. Downward-pushing force
on arcuate portions 24 and 26 of ring portion A will then cause
ring portion A to move downwardly on neck 42 of jar C and beneath
bumper roll 44. In a preferred arrangement, the periphery of oval
opening 14 is substantially the same as the exterior circumference
of bumper roll 44 so that ring portion A may be readily applied
thereover. When the handle of the present invention is deformed in
this manner, arcuate portions 24 and 26 are deformed out of the
plane in which they were originally formed so as to lie on the
surface of a cone with arcuate edges 38 and 40 facing upwardly as
shown in FIG. 3. Oval opening 14 will also have been deformed into
a substantially circular shape as shown in FIG. 2, and
substantially conforms to the circular shape of jar C beneath
bumper roll 44. The memory of the plastic from which the handle is
formed is such that arcuate portions 24 and 26 attempt to return to
their flat oval shape shown in FIG. 1 so that arcuate edges 38 and
40 are constantly biased into tight engagement with surfaces of jar
C beneath bumper roll 44 thereon. This very tight engagement of
ring portion A with jar C prevents ready removal of the handle from
jar C under normal conditions of use.
When arcuate portions 24 and 26 of ring portion A are deformed to
the condition shown in FIGS. 2 and 3, those portions of ring A
adjacent major axis intersecting points 20 and 22 will curve
upwardly as best shown in FIG. 3. Those areas of ring portion A on
opposite sides of major axis intersecting points 20 and 22 will
then slope downwardly toward the outer edges of arcuated portions
24 and 26 as shown in FIG. 3. This downward slope is also imparted
to connecting areas 34 and 36 between arms 28 and 30 and ring
portion A. With areas 34 and 36 lying on the same side of major
axis 16 as bail B, this downward slope will also be imparted to
bail B. The downward slope biases bail B tightly against the outer
surface of jar C as shown in FIG. 3. This strong downward bias also
makes it possible for finger grip portion 32 of bail B to curve
slightly in conformance with the curvature of jar C. Therefore,
finger grip portion 32 of bail B along with arms 28 and 30 tightly
hug the exterior surface of jar C so that bail B does not interfere
with packing or storage of a plurality of jars C closely adjacent
one another, and bail B is not likely to be snagged by a person's
fingers or other articles to accidentally overturn jar C.
In use, finger grip portion 32 of bail B may be grasped in a
person's fingers and lifted upwardly to the shadow line position
shown in FIG. 3, and to the full line position as shown in FIGS. 4
and 5. In this position, finger grip portion 32 extends above and
across the top of ring portion A. Arms 28 and 30 are readily
flexible so that they may bend under a lifting force applied to
finger grip portion 32 so that bail B will move to the shadow line
position shown in FIG. 3. As an important feature of the present
invention, it will be noted that a lifting force applied to finger
grip 32 of bail B, and movement of bail B to the shadow line
position shown in FIG. 3, will operate to apply forces on
connecting areas 34 and 36 which will attempt to return those areas
to their flat condition of FIG. 1 from the downward sloping
condition shown in FIG. 3. This action, which attempts to return
connecting areas 34 and 36 to their flat condition, also creates
forces which attempt to pull arcuate portions 24 and 26 of ring
portion A toward one another. Therefore, lifting action on bail B
causes arcuate edges 38 and 40 of arcuate portions 24 and 26 to
grip jar C beneath bumper roll 44 thereof with even greater force.
When the lifting force is removed from bail B, the resilient memory
characteristics of the thermoplastic polyethylene from which the
handle is made will cause bail B to automatically move from the
shadow line position shown in FIG. 3 back to the full line position
in which it tightly hugs the exterior surface of jar C. Due to the
wedging action provided by lifting forces on bail B, which cause
arcuate portions 24 and 26 to be squeezed toward one another, it is
possible to use the handle of the present invention on jars or
bottles having bumper rolls of varying diameters. That is, it is
not necessary that oval opening 14 become completely circular when
applied to the neck of a jar. For example, a jar having a neck
diameter sufficient to require positioning of arcuate portions 24
and 26 on the surface of a cone will still make the handle operable
even though opening 14 does not become completely circular and is
still somewhat oval shaped.
It will be noted that the downward bend of connecting areas 34 and
36 causes arms 28 and 30 to be deformed not only along lines
radially of major axis 16, but along lines sloping with respect to
minor axis 18 as well, so that arms 28 and 30 are twisted slightly.
This twisting of arms 28 and 30 is in a direction which causes
finger grip portion 32 to curve slightly upward so that it more
readily conforms to the curvature of jar C. In addition, this
curvature of finger grip portion 32 remains even when bail B is
raised to the position shown in FIGS. 4 and 5. With this desired
curvature, the center of finger grip portion 32 lies more nearly in
a position directly above the centerline of the neck opening in jar
C even though arms 28 and 30 are connected with ring portion A on
one side of major axis 16. This permits jar C to hang more nearly
vertical when being carried by a person holding finger grip portion
32 of bail B. While many different dimensions may be provided for
oval opening 14, it has been found that the desired action of the
container handle made in accordance with the present invention is
optimum when major axis 16 is approximately one and one-half times
as great as minor axis 18. That is, an oval opening 14 having a
major axis 16 in the range of one and one-fourth to two times as
great as minor axis 18 provides a most desirable gripping action
and downward bias to bail B. While an oval opening 14 having such a
relationship may be elliptical, it will be recognized that shapes
deviating from an ellipse may also be used as long as the desired
gripping action and downward bias of the bail is achieved.
While the invention has been described with reference to a
preferred embodiment, it is obvious that modifications and
alterations will occur to others upon the reading and understanding
of this specification.
