Description
FIELD OF INVENTION
This invention relates to a shipper package. In particular this
invention relates to a shipper package for shipping drinking straws
and a unitary blank for forming same.
PRIOR ART
Drinking straws are generally packaged in a paper board carton
which has a length equal to the length of the straws. Frequently a
portion of the carton is designed to be torn off to provide a
dispensing opening for straws. During shipping of the packages the
dispensing opening is covered with a transparent plastic material
which is glued to the inside of the carton. Difficulty has been
experienced in attempting to glue this plastic window into the
carton such that it will present an eye-pleasing appearance in use.
Frequently the windows are very loose and can become creased in
shipping. As a result of these packaging difficulties the viewing
windows and the dispenser openings in conventional straw packages
tend to be rather small. In order that the purchaser may have a
clear indication of the nature of the contents of the package it is
desirable to provide as large a viewing window as possible, however
with the existing shipper packages the windows have been relatively
small in order to overcome the difficulties encountered in securing
the transparent material to the package.
Drinking straws are a relatively inexpensive item and consequently
it is important to provide a package which is inexpensive to
manufacture and load with the straws. The conventional packages
which have a viewing window tend to be rather expensive while the
inexpensive packages do not have a viewing window.
SUMMARY
The present invention provides an improved shipper package for
straws which is adaptable to form a convenient dispenser for
straws.
According to an embodiment of the present invention a composite end
cap assembly for forming a pair of end caps for a shipper package
comprises a sleeve which is closed at its bottom end and open at
its upper end and has top wall closure means for closing the upper
end. The sleeve is weakened in a plane which extends transversely
relative to the longitudinal axis thereof whereby it may be severed
along the weakened plane to form an upper end cap and a lower end
cap of a shipper package, the combined length of the upper and
lower end caps being from one third to one half the length of the
straws to be shipped therein.
According to a further embodiment of the present invention the
composite end caps are formed from a unitary paper board blank.
The present invention also provides a method of forming a shipper
package containing drinking straws comprising the steps of forming
a tubular sleeve which is closed at its lower end and open at its
upper end, loading the straws into the sleeve and tearing the
sleeve along a transversely extending weakened score line to form
an upper end cap and a lower end cap. The upper end cap is moved
upwardly over the straws to be located at the upper end thereof and
the open upper end is closed over the upper end of the straws. The
straws and end caps are then enclosed within a transparent
wrapper.
PREFERRED EMBODIMENT
This invention will be more clearly understood after reference to
the following detailed specification read in conjunction with the
drawings wherein:
FIG. 1 is a plan view of a unitary blank according to an embodiment
of the present invention,
FIG. 2 is a pictorial view of a first step in the assembly of the
blank of FIG. 1.
FIG. 3 is a pictorial view similar to FIG. 2 showing a further step
in the assembly of the blank.
FIG. 4 is a pictorial view of a sleeve loaded with straws just
prior to tearing along the weakened score line.
FIG. 5 is a pictorial view of a shipper package according to an
embodiment of this invention.
In FIG. 1 of the drawings the reference numeral 10 refers generally
to a unitary paperboard blank according to an embodiment of the
present invention. The blank 10 consists of six sidewall-forming
panels 12, a pair of top wall closure panels 14 and bottom wall
forming a panels consisting of a hexagonal panel 16, a pair of
panels 18, a pair of panels 20 and a single panel 22. A closure
flap 24 is integrally connected to one longitudinal edge of the
sidewalls forming panels 12 and adapted to be secured as will be
shown hereinafter to the glue patch 26 which is formed adjacent to
the other longitudinal edge of the sidewalls forming panels 12.
In the first step in the assembly of the package the panels 16, 18
and 20 are folded inwardly upon panels 12 to the position shown in
broken lines in FIG. 1. In this position the panel 16 is folded
along the transverse fold line 28 and the panels 20 are folded
along the obliquely disposed foldline 30. Glue patches 32, and 34
are formed on the panels 16, and 20 respectively and these patches
are arranged to face outwardly when the flaps are folded to the
position shown in broken lines in FIG. 1.
A further step in the assembly of the package is shown in FIG. 2 of
the drawings wherein the panels 12 are folded along a vertical
hinge line so that the glue patch 32 on the panel 16 will be
secured to the panel 22 and the glue patch 34 formed in the panel
20 is secured to the panel 18. The blank is then folded along a
further vertical fold line as shown in FIG. 2 to secure the glue
patch 34 of the other panel 20 to the other panel 18. In addition
the glue panel 26 is secured to the flap 24.
The knocked down configuration of the assembled sleeve is shown in
FIG. 3 of the drawings. To erect the sleeve from the position shown
in FIG. 3 the panels 12 are moved away from one another in the
direction of the arrows shown in the FIG. 3. .The bottom wall
forming panels 16, 18, 20, and 22 are connected to one another such
that upon moving the side wall panels in the direction shown in
FIG. 3 they will automatically move into a position in which they
form a bottom end wall closure as shown in FIG. 4. A plurality of
drinking straws 36 are loaded into the open upper end of the sleeve
as shown in FIG. 4.
An important feature of the present invention is the provision of a
weakened tear line 40 which extends transversely along the side
walls panels 12 from one end thereof to the other. When the sleeve
is assembled as shown in FIG. 4 it is severed along the weakened
score line 40 to form a lower end cap forming portion 42 and an
upper end cap forming portion 44. The upper end cap forming portion
44 is slid along the straws in the direction of the arrows shown in
FIG. 4 to a position wherein the end walls forming flap 14 may be
folded over the free ends of the straws.
A transparent wrapper 46, preferably in the form of a heat-shrink
wrapping material, is wrapped around the assembled straws and end
caps to form a composite shipper package as shown in FIG. 5 of the
drawings. When a heat-shrink wrapper is used the packages are
heated in a conventional manner to shrink the wrapper into a close
fitting engagement with end caps and straws.
When the package is opened in use the wrapper is removed and
discarded. If the total amount of paperboard material in the end is
reduced to a minimum the overall height of the bottom end cap may
not be sufficient to retain the straws therein if the upper end cap
were removed. This difficulty is overcome by sliding the top end
cap forming portion downwardly over the straws so that it is
returned to the position shown in FIG. 4. In this position the
combined height of the lower and upper end caps cooperate to form a
dispenser package with the straws projecting out of the upper end
thereof. When the combined length of the upper and lower end caps
is equal to one-third to one-half of the total length of the
drinking straws the package will then act as a convenient
dispenser.
From the foregoing it will be apparent that the present invention
provides a simple and inexpensive shipper package for drinking
straws and the like.
Various modifications of the present invention will be apparent to
those secured in the art without departing from the scope of the
invention. For example only one end wall closure panel may be
employed and this may include a small tuck tab for securing it in
the closed position.
