BI-COLORED WRAPPER TWIST TIE
Abstract
A bi-colored twist tie to provide an air tight closure for one
end of a wrapper of the type commonly used for certain types of
bakery products such as bread, rolls, buns, etc. The tie strip is
substantially vertically divided into two portions providing
respective contrasting colors to enable a person opening the
wrapper to easily detect the directions of twist. Various
combinations of contrasting colors may be used to indicate the
baking date. A color key may be provided on the wrapper for this
purpose.

Claims
What is claimed is:
1. A Twist Tie Strip for use in providing an air tight closure for
the normally open end of a wrapper of the types of bakery products
such as bread, rolls, buns, etc., comprising an elongated, narrow
strip of any suitable material with a thin wire embedded therein
generally along the length of its longitudinal axis, said strip
being generally, vertically divided into two halves defined by two
contrasting colors, wherein said strip is provided in a plurality
of different contrasting colors one color of each strip designating
a particular day of the week on which the product in the wrapper
was baked, including a color key on said wrapper, associated with
said plurality of different contrasting colors to identify the days
of the week.
Description
STATE OF THE PRIOR ART
For many years, both ends of wrappers containing bakery goods such
as bread, rolls, buns, etc. were sealed shut on both ends. While
this closure method was very effective in keeping the product fresh
until it reached the consumer, it presented problems once the
wrapper was opened for use. In most instances, a portion of the
contents was removed from the wrapper and the open end was simply
folded loosely shut resulting in a rapid loss of freshness.
In more recent years, a twist tie strip has been used to seal one
end of the wrapper at the bakery. The twist tie strips, currently
in use, are generally comprised of a relatively thin strip of
plastic about 4 inches long and one-eighth of an inch wide with an
axially extending thin wire embedded in the plastic. The obvious
advantage of the twist tie strip is that it can be reused over and
over with the result that the remaining contents of the wrapper
retains its freshness for a much longer period of time.
One problem presented by twist tie strips of this general type is
that the resulting twist is very tight and this fact combined with
the narrow width and the thinness of the material generally results
in a condition wherein may people cannot discern the direction of
the twist, resulting in a trial and error method of opening
same.
BACKGROUND OF THE PRESENT INVENTION
The present invention pertains to a bi-colored twist tie to provide
an air tight closure for one end of a wrapper of the type utilized
for bakery products such as bread, rolls, buns, etc.
One of the principal objects of the present invention is to provide
a twist tie which is generally centrally, vertically divided into
two portions providing respective contrasting colors to enable a
person, opening the wrapper to readily discern the direction of
twist.
Another object of the present invention is to use various
combinations of contrasting colors, color keyed to the days of the
weeks, indicated on the wrapper, to indicate the baking date. As an
alternative, the baking date may be printed directly on the tie
strip.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a fragmentary side elevational view of a loaf of bread in
a wrapper with the end thereof tied shut with a bi-colored twist
tie in accordance with the present invention;
FIG. 2 is a plan view of one form of bi-colored twist tie of the
present invention; and
FIG. 3 is a plan view of a modified form of bi-colored twist
tie.
DETAILED DESCRIPTION OF THE DRAWINGS
With reference to the drawings in which like reference characters
designate like or corresponding parts throughout the various views
and with particular reference to FIG. 1, the numeral 10 generally
designates a loaf of bread in a conventional wrapper 12 with a
bi-colored twist tie 14 in accordance with the present invention
engaged about the gathered, normally open end 16 of the wrapper 12.
thereof or,
As illustrated in FIGS. 1 and 2, the twist tie strip 14 is divided
along a substantially, vertical, central line into two portions
providing respective contrasting colors such as white at 18 and red
at 20. Twist tie strips of this nature may be constructed of a
laminated paper material with a thin wire extending between the
plies of paper along the longitudinal axis thereofor, as
illustrated, a thin wire 22 longitudinally embedded in a strip of a
thin plastic material 24.
In use, the open end 16 of the wrapper 12 is gathered, the twist
tie strip is wrapped therearound and the two extending ends are
twisted together as illustrated in FIG. 1. With the use of the
contrasting colors on the respective end portions, the direction of
the twist is readily discernable to any one attempting to open the
wrapper end.
Conventional twist tie strips, now in use, are of a single color
and it is extremely difficult for persons with even a close up
sight deficiency to discern the direction of twist. It therefore
becomes a matter of trial and error to open the wrapper end. When a
single color twist tie strip is twisted tightly, it is in fact very
difficult for persons with good eyesight to see the twists because,
by its very nature, the width of the strip becomes deformed and the
twisted portions tend to merge and blend together. However, with
the use of the bi-colored twist tie strip of the present invention,
the color distinction is readily discernable despite any
deformations thereof.
The contrasting colorcombination may be keyed to the baking date of
the product contained in the wrapper 12 as illustrated in FIG. 1.
In this event one color such as the white 18 would remain constant
for seven different twist tie strips and a different contrasting
color would be provided on the opposed end portions thereof, each
contrasting color would indicate a different baking day of the
week. A color key 26 would be provided on the wrapper 12. For
example the colors red, yellow, greem, blue, purple, brown and
black would respectively indicate the particular day of the week on
which the product in the wrapper 12 was baked.
As indicated in FIG. 3, the name of the day of the week on which
the product was baked may be printed on one end portion of the
twist tie strip as indicated at 26.
The particular colors referred to and their respective references
to particular days of the week are strictly by way of example only
and are not intended to be limiting.
