Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to cartons adapted for storing and
displaying squeeze tubes and more particularly to cartons having
means for retaining the squeeze tube in position in a display
opening within the carton.
2. Description of the Prior Art
Deformable plastic tubes for use by consumers are presently shipped
and displayed in a variety of paperboard shadow boxes which allow
the consumer to see at least one side of the squeeze tube and
facilitate removal of the tube from the carton. The present
invention is directed to improvements in such cartons for
displaying squeeze tubes.
SUMMARY OF THE INVENTION
A carton for use with deformable dispensing tubes with a
transversal opening cut in the front panel to form an upper
retaining section, a lower section divided into two shadow panels,
and a cap restraining section located at the bottom of the opening,
the cap restraining section having inwardly foldable flaps which
frictionally engage each side of the cap to hold it in position in
the carton.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As seen in FIG. 1, the package consists of a carton 10 which is
particularly adapted to hold a display tube 11 which has fitted on
one end thereof a cap 12. The blank shown in FIG. 6 is typical of
the blank from which such a carton may be made, and is normally
fabricated from foldable paperboard or similar sheet-like material
and includes a back panel 20, side panels 22 and 23, and any of the
conventional means for closing the carton such as a manufacture's
glue flap 25. A front panel shown generally as 30 completes the
panel array and will be described in more detail later. The top of
the carton is closed by conventional closing flaps, and as shown
include a main top flap 40 hingedly connected along the fold line
41 to the back panel 20 and is formed in size substantially equal
to the area of the top end of the carton 10. A tuck-in flap 42 is
hingedly attached to the top of the flap 40 on fold line 43 and
additional closure flaps 44 and 45 are hingedly attached along fold
line 41 to the side panels 22 and 23 respectively, which may be
folded together to affect a complete closure.
The front panel of the carton 30 is divided into upper and lower
sections numbered 30a and 30b by a transverse cut line 31 which
extends horizontally across the front panel 30 and into the side
panels 22 and 23 in order to form a pair of inwardly movable shadow
panels 32 and 33 on either lateral side of the lower section 30b.
It can be seen in FIG. 6 that the respective panels of the carton
are joined by vertical hinge lines 50, 51, 52 and 53 which allow
the blank to be folded into a tubular relationship. Vertical fold
lines 52 and 53 also provide the inwardly movable shadow panels in
the front panel 30b with the ability to move inwardly since the
transverse line cut 31 extends into the side panels 22 or 23, which
line cut may include downwardly extending portions 31a.
The shadow panels 32 and 33 are connected by a fold line 46 which
is positioned above an opening for receiving the squeeze tube which
can be seen as 60 and is formed in the front panel in such a manner
that it extends downwardly to the bottom edge of the front panel.
In the particular embodiment shown there are small extensions of
the shadow panels 32 and 33 which are shown as 32a and 33a which
extend into the opening 60 but which are separated by a line cut 61
and may therefore move apart when the shadow panels 32 and 33 are
flexed inwardly to receive the tube 11. The extensions 32a and 33a
are connected along fold lines 35 and 36.
Toward the lower end of the front panel 30 are formed secondary
generally triangular shadow panels 70 and 71 and are defined by
angled score lines 72 and 73 in the shadow panels 32 and 33 and
also are hingedly attached along the bottom fold line 75. These
panels flex inwardly along with the shadow panels 32 and 33 when
the tube 11 is inserted, but they do so at a different angle than
the shadow panels 32 and 33, and therefore enhance the framing
effect of the carton 10.
Attached to the bottom of the front panel 30 along the hinge line
75 is a first bottom closure flap 80 which substantially covers the
bottom end of the carton 10 in its final folded position and which
has a tuck-in flap 81 attached along the hinge line 82 which, in
conjunction with the bottom closure flaps extending from the side
panels shown as 85 and 86 provide an effective closure carton.
At the bottom of the opening 68 a pair of hingedly connected cap
retaining flaps are provided on each side of the opening 60. A
first flap 90 is foldably connected to the generally triangular
shadow panels 70 along a fold line 91 while a similar first flap 92
is connected to the opposite generally triangular panel 71 along a
fold line 93. The fold lines 91 and 93 are generally aligned with
the sides of the opening 60. A second flap 94 is hingedly connected
to the bottom closure flap 80 along a fold line 95, and a similar
second flap 96 is foldably connected to the bottom closure flap 80
along a fold line 97. The fold lines 95 and 97 are angularly
related as shown in FIG. 6 to form a shallow V-shaped notch in the
bottom closure flap 80. The second flaps 94 and 96 are separated
along a central cut line 98. The first and second flaps 90 and 94
are hingedly connected by an upwardly and inwardly extending
diagonal fold line 99, and the first and second flaps 92 and 96 are
similarly connected by an upwardly and inwardly extending diagonal
fold line 100.
The cap retaining flaps described are an important feature of the
invention. When the carton 10 is erected and the tube 11 is
inserted, the second flaps 94 and 96 are folded beneath the tube
cap 12 as indicated in FIGS. 1 and 3 of the drawings. The insertion
of the tube cap 12 forces the first flaps 90 and 92 inwardly into
the carton 10 to permit the cap 12 to pass between them. After the
center of the cap passes the edges of the first flaps, the edges of
the first flaps spring back to engage the cap forwardly of the
center thereof to positively lock the tube cap within the carton
and to prevent rotation of the cap. The position of the first flaps
90 and 92 relative to the tube cap 12 is best indicated in FIGS. 3
and 5 of the drawings.
If it is desired, the shadow panel extensions 32a and 33a may be
omitted or if the tube to be displayed is small in cross section
the line cut 61 may be changed to a simple score line. It can be
seen that the crimped end of the tube is held between the back of
the top panel section 30a and the front of the lower panel section
30b with the cap pressed into the cap retaining section at the
bottom of the opening 60.
In accordance with the Patent Statutes, I have described the
principles of construction and operation of my improvement in TUBE
DISPLAY CARTON; and while I have endeavored to set forth the best
embodiment thereof, I desire to have it understood that obvious
changes may be made within the scope of the following claims
without departing from the spirit of my invention.
