Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to containers for use in housing and
dispensing cigarettes or like articles. More particularly, this
invention relates to a type of cigarette package normally referred
to in the industry as a hard pack, being comprised of a more rigid
material than the typical soft cup cigarette package.
Specifically, the package of this invention is comprised of an
inner and outer shell with the inner shell being swingable relative
to the outer shell to expose a portion of the top of the inner
shell laterally of the outer shell so that cigarettes may be
extracted from the exposed portion. The inner shell is swingable
back to a position within the outer shell so that the cigarettes
are fully protected.
2. Description of the Prior Art
The packaging of cigarettes and like articles poses numerous
problems to the tobacco industry. It is desirable of course, to
provide a package that facilitates use by the consumer while at the
same time provides protection for the cigarettes during processing,
shipment and as being utilized by the consumer.
Cigarette packages are carried by consumers in pockets, purses,
rolled in socks, shirts and other clothing articles. Often the
packages are subjected to abuse particularly during periods of
heavy exertion by the user. In such instances, physical abuse is
combined with increased moisture content to cause deterioration of
the cigarettes.
Maximum protection is attained for cigarettes or like products by
the use of a hard type pack as opposed to the typical soft pack
characterized by a combination of a metal foil-paper laminate and a
paper label. The hard pack cigarettes from being mashed or bent as
well as providing increased protection against moisture.
Hard packs, however, have met with varying degrees of limited
success. Perhaps the most successful form of hard type pack has
been the well known flip-top box.
One reason for the limited success of the hard pack is decreased
accessibility to the cigarettes. The structure of most hard packs
makes it difficult for the consumer to extract cigarettes using
only one hand. Often the consumer must hold the pack with one hand
and remove a top or other lid like structure to gain access to the
cigarettes. This poses problems in numerous situations where only
one hand is or should be available--that most readily apparent
being the driving of a vehicle.
Where hard packs have been provided with are operable with one
hand, other difficulties have been encountered. For instance, such
packages can be complicated and expensive to manufacture or they
provide only limited protection to the cigarettes.
Some hard packs subject the cigarettes to abrasive action during
the opening and closing movements. In such instances the cigarettes
become damaged by loosened ends or some tobacco, particularly
fines, are shaken from the cigarettes and ultimately find their way
into pockets, purses or other places where the cigarette package is
housed to provide a nuisance.
It is also important that such hard packs not be subject accidental
opening which could expose the cigarettes to damage. In addition,
the package should be easily retained in an open position while a
cigarette is being extracted. Unless this latter feature is
achieved, the consumer will be caused to fumble about with the
package during one handed opening operations. Thus, it is critical
that the package remain either closed and open until pressure is
deliberately applied for the purpose of reversing its position.
While various attempts have been made in the prior art to alleviate
the difficulties previously discussed, the packages developed have
been deficient in several respects. For instance, most recently a
U.S. patent, issued to Gero No. 3,749,234, disclosing a cigarette
package having an inner and outer shell-- the inner shell being
rotatable laterally of the outer shell to expose a portion of the
top of the inner shell from which cigarettes may be extracted. This
package is manufactured from a relatively complicated blank folded
and adhered in numerous places to provide not only the shells but a
"snap-lock" device which limits the outward swinging movement of
the inner shell.
In the Gero patent, the inner shell does not fully house the
cigarettes. When the package is in a closed position, as
illustrated in FIG. 5, a portion of the cigarettes is exposed above
the upper edge of the inner shell. In addition, as the inner shell
is rotated to its open position, the cigarettes, as seen in FIG. 3,
pivot on the bottom panel of the outer shell. This pivoting
movement causes the ends of the cigarettes to loosen, which effects
burning and causes tobacco fines and other particles of tobacco to
be displaced from the tobacco column. Tobacco in the form of fines
or strands which become loosened in packages of this nature are
ultimately leaked into pockets, purses and other places resulting
in a nuisance for the consumer.
A frictional engagement between the cigarettes and the package may
also occur at the top panel of the Gero package. Similar damage to
that discussed above would result where plain end cigarettes are
housed in the package. In regard to filter cigarettes, such
abrasion of the filter can damage the filter effecting its
filtering capabilities and producing a filter end condition
annoying to the consumer.
An earlier patent issued to Benjamin, U.S. Pat. No. 3,052,398,
provided a more desirable inner shell that more fully protected the
cigarettes. While the Benjamin package avoids certain of the damage
to the cigarettes inherent in the Gero patent, it has other
undesirable features. For example, no means is provided in the
Benjamin package for limiting the rotational movement of the inner
shell relative to the other shell. In addition, the only way of
grasping the inner shell and removing it from the outer shell is
along the same edge of the inner shell that would be exposed. This,
along with the failure to include a means for limiting the rotation
of the shell produces a package which is difficult to open and
close using a single hand.
Moreover, it is not apparent that the inner shell of Benjamin would
stay within the outer shell during periods of non use. The inner
shell, for instance, is cut away along its back portion and
provides no frictional contact with the under surface of the top
panel to inhibit rotation.
Other package structures having an inner shell swingable relative
to an outer shell were considered during preparation of this
application, specifically, U.S. Pat. Nos. 356,244, 1,735,325,
1,992,373, 3,037,678, and 3,583,625. In addition, the following
patents disclosing packages having swingable lid-type structures
were also considered, U.S. design patent Nos. 136,319 and 174,305
and U.S. Pat. Nos. 1,240,563, 1,919,100, 2,265,828, 2,956,722,
2,958,418, 3,207,416 and 3,265,282.
It is a primary object of this invention to provide a new and
improved hard type package for housing and dispensing cigarettes or
like articles that alleviate the aforementioned difficulties in the
art.
It is a further object of the invention to provide such a new and
improved package that is constructed in a simple and efficient
manner.
Another object of this invention is to provide such a package that
will open and close with ease utilizing only one hand to facilitate
the extraction of cigarettes during driving and other situations
where the other hand is or should be occupied.
It is also an object of this invention to provide such a package
wherein the cigarettes are fully protected from damage during
normal use.
It is another object of the invention to provide such a package
which is easily opened and closed but wherein the opening and
closing of the package does not itself result in any damage to the
cigarettes or produce tobacco fines which can annoy the
consumer.
An additional object of this invention is to provide such a package
which will not open or close without an exertion of pressure on the
inner shell for movement, either to or from the open position.
It is also an object of this invention to provide a blank for
forming the package or components of the package comprised of
simple rectilinear parts, fold, score and cut lines which is easily
and inexpensively stamped and assembled to provide the desired
package.
Additional objects and advantages of this invention will be set
forth in part in the description which follows and in part will be
obvious from the description or may be learned by practice of the
invention. The objects and advantages of the invention may be
realized and attained by means of the instrumentalities and
combinations particularly pointed out in the appended claims.
SUMMARY OF THE INVENTION
To achieve the foregoing objects and in accordance with the purpose
of the invention as embodied and broadly described herein a package
is disclosed for cigarettes or other like articles comprising an
outer shell having opposed front and rear wall panels and top and
bottom panels connecting said wall panels thereby defining a shell
having a pair of opposed open sides, the bottom panel having first
and second portions.
An inner shell is also disclosed containing the cigarettes or other
articles and positioned within the outer shell. The inner shell has
opposed front and rear wall panels and side panels connecting said
wall panels. At least a portion of at least one of the side panels
extends between the first portion of the bottom panel and the top
panel of the outer shell. The inner shell is connected to the first
portion of the bottom panel of the outer shell.
Hinge means on the bottom panel of the outer shell connect the
first and second portions to provide swinging movement of the first
portion relative to the second. In this manner the inner shell is
rotatable to and from a first position within the outer shell and a
second position angularly disposed relative to the outer shell such
that a portion of the top of the inner shell is exposed laterally
of the outer shell to provide access to the cigarettes.
At least a portion of the top edge of the inner shell is movable
into a sliding engagement with the under surface of the top panel
of the outer shell upon rotation of the inner shell to the second
position. This frictional engagement limits the opening and closing
of the package except by pressure applied to the inner shell while
holding the outer shell against movement.
An abutment means is provided on the under surface of the top panel
of the outer shell for engagement with the top edge of the inner
shell to limit the rotation of the inner shell when it has reached
its second position.
In addition, and also to achieve the foregoing objects, and in
accordance with the purpose of the invention as embodied and
broadly described herein, a blank is provided which is easily
stamped and assembled to form the outer shell of the package for
housing and dispensing cigarettes or like articles as described
above. In addition, a second blank is provided wherein said inner
and outer shells above described can be formed from a single blank
and easily stamped and assembled into a complete package.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, a package 10 is illustrated and
comprised of an outer shell 12, an inner shell 14, a liner 16 and a
closure member 18. The outer shell 12 houses inner shell 14 in such
a manner that shell 14 is rotatable from a first position as
illustrated in FIG. 1, within the confines of outer shell 12, to a
second position, as illustrated in FIG. 2, where a portion of inner
shell 14 is exposed laterally of outer shell 12.
In accordance with the invention, the liner 16 is comprised of a
paper foil laminate of 0.00025 inch aluminum foil and 28 or 30
pound paper. Liner 16 is comprised of front and rear wall panels 17
and 19, side panels 21, bottom panel 23 and top panel 25 to provide
a protective enclosure for the cigarettes or other articles housed
within package 10.
Referring to FIGS. 1 and 3, the closure member 18 is comprised of a
sheet of material preferably paper having opposed end portions 27
secured to the front and rear wall panels 17 and 19 of the liner 16
and a center portion 29 extending across a portion of the top panel
25. preferably the end portions 27 are adhered to the wall panels
17 and 19 by a suitable adhesive.
The center portion 29 of the closure member 18 includes an edge 31
defining a tearing guide so that a portion of the top panel 25 may
be neatly torn away to obtain access to the cigarettes or other
articles housed in package 10. In order to obtain an even tear of
the paper-foil laminate it is important that the end portions 27 of
the closure member 18 be secured to the liner 16 rather than the
inner shell 14. This is particularly critical when the liner 16 and
the housed cigarettes are recessed below the top edge of the inner
shells as in the prefered embodiment of this invention.
The package 10 also includes a label of 50 to 60 pound paper, a
transparent overwrap and a tear tape. These conventional components
are not illustrated.
In accordance with the invention, outer shell 12, as illustrated in
FIGS. 1 through 6, is comprised of a pair of opposed front and rear
wall panels 20 and 22 respectively with a top panel 24 and a bottom
panel 26 connecting wall panels 20 and 22. The panels of shell 12
therefore define a pair of opposed open sides and a through
passageway or interior chamber, for housing inner shell 14.
In the illustrated embodiment, top panel 24 is comprised of members
28 and 30 which are integrally formed with rear and front wall
panels 22 and 20 respectively. Member 28 is disposed in overlying
relation to member 30 and adhered thereto to form top panel 24. It
is anticipated that top panel 24 could be formed in other ways and
in fact could be integral with both the front and rear wall panels
20 and 22.
As illustrated, bottom panel 26 is integral with front and rear
panels 20 and 22 and is divided into a first portion 32 and a
second portion 34. The second portion 34 is integral with front and
rear wall panels 20 and 22 and is connected to first portion 32 by
a hinge means illustrated herein as a score line 36.
The first portion 32 is free to swing relative to second portion 34
from a position in planar alignment with portion 34 through an arc
downwardly from the plane of portion 34. The inner shell 14 is
connected to first portion 32, the score line 36 thus permitting
the swinging movement of inner shell 14 to an open position, as
illustrated in FIG. 2, and back to its closed position, as
illustrated in FIG. 1.
It should be noted that score line 36 is provided at a point over
half way across the length of bottom panel 26. Thus, portion 32 is
greater in length than second portion 34. By placing score line 36
beyond the center point of bottom panel 26 in a direction away from
the side of outer shell 12 through which inner shell 14 moves to
its open position, allows inner shell 14 and outer shell 12 to be
snuggly fitted in a vertical direction yet permits the rotation of
the inner shell to its open position. The snug fit assists in
retaining the inner shell in its closed position. This feature also
permits inner shell 14 to be constructed to the full height of the
cigarettes providing for protection of the cigarettes.
The positioning of the score line 36 also provides for a sliding
engagement of a portion of the top edge of inner shell 14 with the
under surface of top panel 24 of outer shell 12. This sliding
engagement, not only acts against accidental opening of the
package, but also provides assistance in retaining the inner shell
14 in its open position when cigarettes are being extracted. In
effect, the frictional engagement of these surfaces is such that a
positive force must be provided to either open the package or close
the package.
The positioning of score line 36 is critical to operation of the
package 10. Movement of score line 36 nearer the open side of the
outer shell 12 through which the inner shell 14 rotates causes
increased frictional engagement between the under surface of top
panel 24 and inner shell 14. This frictional engagement increases
to a point that rotation of the inner shell is prevented unless the
heights of inner shell 14 and outer shell 12 are varied to or from
a space at the top of the outer shell. This, however, reduces the
snug fit which serves not only to protect the product but to retain
the package in the closed position. Movement of the score line away
from the aforestated open side of the outer shell 12 reduces the
frictional engagement and detracts from the ability of the package
to be retained in either an open or closed position until positive
pressure is applied to reverse that position.
It has been found than an operable package can be provided where
the first portion 32 extends over a range of about 50 percent to
about 75 percent of the length of the bottom panel 26. However, for
best results the first portion 32 should extend over a range of
about 55 percent to about 60 percent of the length of the bottom
panel 26. In this latter range, it has been found that exceptional
results are obtained over prior art packages in that sufficient
frictional engagement is attained that the inner shell 14 will not
move until pressure is exerted to reverse the condition of the
package 10 from open or closed positions. The desired frictional
engagement is achieved within the stated preferred range without
deforming the components of the package 10, for damaging the
contents of package 10.
In accordance with the invention, an abutment means is provided on
the under surface 38 of top panel 24 for limiting the swinging
movement of the inner shell 14. In the illustrated embodiment, the
abutment means is defined by an abutment surface 40 on tab member
42. Tab member 42 is integrally formed with member 30 of top panel
24 by being cut from member 30 and folded out of the plane of
member 30 into an adjacent lower plane and adhered to the under
surface of member 30.
It is anticipated that various means may be employed to provide
such an abutment surface 40. For instance, in FIG. 10 a
modification is illustrated which will be described later
herein.
In accordance with the invention, inner shell 14 is comprised of
opposed front and rear wall panels 44 and 46 respectively and side
panels 48 and 50 connecting said wall panels 44 and 46. In
addition, inner shell 14 includes a bottom panel 52. The shell 14
therefore defines a structure closed on all sides except one. The
top edges 54 of the front and rear panels 44 and 46 and the side
panels 48 and 50 define an opening through which an inner liner 16
is received, as best illustrated in FIG. 3.
In the illustrated embodiment side wall 48 is comprised of a pair
of members 56 and 58 positioned adjacent one another and adhered
together along the length of side wall 48. The members 56 and 58
are integral with rear and front panels 46 and 44 respectively. In
the preferred embodiment, side panel 50 is integral with the front
and rear side panels 44 and 46 respectively and is therefore of a
single thickness.
In the preferred embodiment, bottom panel 52 of inner shell 14 is
formed by members 59 and 60 which are integral extensions of front
and rear wall panels 44 and 46 respectively. The members 59 and 60
are bent into a plane normal to that of front and rear wall panels
44 and 46 and are adhered together to form bottom panel 52. In
addition, side panels 48 and 50 are secured to bottom panel 52 by
tabs 62 nd 64 adhered to the upper surface of member 59 of bottom
panel 52.
It is, of course, anticipated that the inner shell may be formed by
other structures and other assemblies however, the package
illustrated in FIGS. 1 through 6 constitutes the preferred
embodiment of this invention.
As best illustrated in FIG. 5, front and rear wall panels 44 and 46
and side panels 48 and 50 of inner shell 14, when positioned within
outer shell 12 extend from the upper surface of bottom panel 26 of
outer shell 14 substantially to the under surface of the top panel
24 of outer shell 12 to provide a snuggly fitting inner and outer
shell combination. In this manner, when inner shell 14 is rotated
to its opened position, the upper edge 54 of side panel 50 of inner
shell 14 slidingly engages the under surface of top panel 24 of
outer shell 12 until it abuts surface 40. A positive exertion of
force on inner shell 14, while holding the outer shell 12, is
required to overcome this frictional engagement to close the
package. This feature facilitates the removal of cigarettes with
one hand by not allowing relative movement between the inner and
outer shells during the cigarette removal operation.
In addition, inner shell 14 is designed of such dimensions that it
covers the full length of the cigarettes which are housed therein.
In this manner the cigarettes themselves are not subjected to any
frictional engagement during the movement of the inner shell 14 and
are therefore not damaged prior to use by the consumer.
The inner shell 14 and outer shell 12 are assembled in closed
position, as illustrated in FIG. 4, with inner shell 14 housed
within outer shell 12. The dimensions of shells 12 and 14 are such
to permit a snug fit between the respective front wall panels 20
and 44 and rear panels 22 and 46. This snug fit assists in holding
the package in a closed position until a positive force is exerted
to open the package.
The shells 12 and 14 are joined by adhering the overlying portion
of bottom panel 52 of inner shell 14 to first portion 32 of bottom
panel 26 of outer shell 12. In this manner, a force exerted on side
panel 50 of inner shell 14 causes the first portion 32 of the outer
shell to swing downwardly out of the plane of bottom panel 26. The
inner shell 14, being adhered to the first portion 32, is rotated
to its exposed open position, as illustrated in FIG. 2.
While in the preferred embodiment of this invention the inner shell
14, is adhered to first portion 32, it may be possible to connect
first portion 32 and inner shell 14 by other means. For instance,
in FIGS. 9 through 14, a modified form of the invention is
illustrated wherein the first portion of the bottom panel of the
outer shell is integrally formed with the inner shell 14.
Referring to FIGS. 7 and 8, blanks 70 and 80 are illustrated for
forming inner shell 14 and outer shell 12. It should be noted that
these blanks contain elements formed by simple rectilinear
configurations. It is in this manner that blanks are provided which
are easily stamped, and perhaps more importantly, are easily folded
and assembled into shells 12 and 14.
In accordance with the invention, a blank 70 is illustrated in FIG.
7 for forming outer shell 12. In order to facilitate an
understanding of the structure of the blank and its relation to
outer shell 12, the same numerals will be utilized to designate
various components. The blank 70 is comprised of front and rear
wall panels 20 and 22, bottom panel 26 and top panel 28. As
previously described, top panel 24 is comprised of a pair of
members 28 and 30 adhered together in shell 12 to form top panel
24. As illustrated, members 28 and 30 are integrally formed with
rear and front wall panels 22 and 20 respectively and connected by
fold lines 74 and 72.
The bottom panel 26, as previously discussed, is comprised of first
and second portions 32 and 34 respectively connected by a hinge 36,
illustrated herein as a score line 76. The second portion 34 of
bottom panel 26 is connected to front and rear wall panels 20 and
22 by fold lines 75 and 77 respectively.
The blank 70 is slotted on each side of the first portion 32 to
ensure that the first portion 32 is free to move in and out of the
plane of the bottom panel 26. While the slotting facilitates this
movement, it is not considered necessary to the invention. Rather,
it is only necessary the blank be cut in these locations in order
to provide for separate swinging movement of the first portion 32
relative to the second portion 34 and the front and rear wall
panels 20 and 22.
As previously discussed, a tab member 42 is provided on member 30
in order to define the abutment surface 40. The tab member 42 is
cut from member 30 by three cut lines 73 and is connected thereto
by fold line 78. In this manner the tab member 42 may be folded
into contacting relation with the under surface of member 30 and
adhered thereto. While there are other ways of defining the
abutment surface 40, it should be recognized that the use of tab 42
provides a rotation limiting means formed from an element of the
blank which is simple and rectilinear in nature.
Referring to FIG. 8, a blank 80 is provided in accordance with this
invention for forming an inner shell 14. Again it should be noted
that the blank 80 is comprised of simple rectilinear line
configurations and is easily folded and assembled into the inner
shell 14.
The blank 80 is comprised of front and rear wall panels 44 and 46
connected by a side panel 50. The side panel 50 is integral with
wall panels 44 and 46 and connected thereto by a pair of parallel
spaced fold lines 82 and 84. Side panel 48 is provided by a pair of
members 56 and 58 integral with wall panels 46 and 44 respectively
and connected thereto by fold lines 88 and 86 respectively. The
members 56 and 58 are foldable into contracting relation and
adhered together as illustrated in FIG. 2 to provide side panel 48
of the inner shell 14.
The bottom panel 52 of the inner shell 14 is comprised of a pair of
members 59 and 60 integrally formed with the front and rear wall
panels 44 and 46 connected thereto by fold lines 90 and 92
respectively. In addition, tab members 62 are provided at the base
of each of the side panels 50 and 48 and connected by fold lines 94
and 96 respectively. As best illustrated in FIG. 3, tab members 62
are folded along lines 94 and 96 and placed in overlying relation
to member 59 and secured by adhesive.
A second embodiment of the invention is illustrated in FIGS. 9
through 15 and designated as package 110. In this embodiment of the
invention, the inner and outer shells are formed from a single
blank--the blank is illustrated in FIG. 15. In addition, a modified
member for defining the abutment surface 40 is provided as best
seen in FIGS. 10 and 14.
For the sake of comparison and clarity, the same numerals are
utilized in relation to FIGS. 9 through 15 as were utilized in
FIGS. 1 through 8.
In accordance with this invention, and as illustrated and discussed
in relation to FIGS. 1 through 8, the outer shell 12 is comprised
of front and rear wall panels 20 and 22, a top panel 24 and a
bottom panel 26. The top panel 24 is formed in the same manner as
illustrated and discussed previously by the placement of a member
28 in overlying relation to member 30 and adhering of the members
together. The top panel 24 differs from that illustrated in FIGS. 1
through 8 in regard to the formation of the abutment surface
40.
Referring to FIG. 10 the abutment surface 40 is formed by a tab
member 100 which is folded out of the plane of member 30 and
adhered to the under surface of member 30. The positioning of tab
100 on the under surface of the member 30 is best illustrated in
FIG. 12.
The inner shell 14 of FIGS. 9 through 15, like that of FIGS. 1
through 8, is comprised of front and rear wall panels 44 and 46 and
side paanels 48 and 50. A basic difference, however, between this
package 110 and package 10 of FIGS. 1 through 8 is that the inner
shell 14 has no separate bottom panel but instead utilizes the
bottom panel 26 of the outer shell 12 to cover its lower side.
As shown in FIGS. 9 and 12, the first portion 32 of the bottom
panel 26 of the outer shell 12 is integral with side panel 48 of
the inner shell 14, being connected by a fold line 102. In contrast
to package 10, the side panel of package 110 is of a single
thickness, whereas side panel 50 is comprised of a double thickness
being made up of members 104 and 106 in the same manner as members
56 and 58 of package 10.
Package 110 operates identically to package 10 in that pressure
exerted on side panel 50 of the inner shell 14 causes the inner
shell to rotate about hinge 36, swinging first portion 32 of bottom
panel 26 downwardly and moving a portion of the top of inner shell
14 laterally of outer shell 12 to expose the contents of inner
shell 14, as best seen in FIG. 10.
As in package 10, the top edge of side panel 50 engages abutment
surface 40 to limit the rotation of inner shell 14 relative to
outer shell 12. It is also noted that the top edge of side panel
50, slidingly engages the under surface of member 30 of top panel
24 to provide frictional resistence against movement. This
frictional engagement serves to retain inner shell 14 both in its
open and closed positions as previously discussed.
Referring to FIG. 15, a blank 120 is illustrated for forming
package 110. As may be seen, blank 120 is a single piece of
material. Like blanks 70 and 80 all elements are rectilinear
providing for easy formation of the blank and assembly into the
desired package.
The blank 120 is comprised of an inner shell portion 14 and an
outer shell portion 12. The outer shell portion 12 is comprised of
front and rear wall panels 20 and 22 respectively connected by
bottom panel 26. The botton panel 26 is integral with wall panels
20 and 22 and connected thereto by fold lines 122 and 124. At the
opposite side of wall panels 20 and 22, members 28 and 30 are
provided and connected thereto by fold lines 124 and 126
respectively.
As previously discussed, surface 40 is defined by tab member 100
connected to member 30 by fold line 130.
In this embodiment, the bottom panel 26 of the blank 120 is divided
into a first portion 32 and a second portion 34, these portions
being connected by hinge means in the form of a score line 132. Cut
lines 134 and 136 are provided between first portion 32 and side
panels 20 and 22.
The inner shell 14 is connected to outer shell portion 12 of blank
120 by means of a fold line 102. Specifically, fold line 102
connects first portion 32 of bottom panel 26 and side panel 48 of
inner shell 14. The side panel 48 is connected to front and rear
wall panels 44 and 46 of the inner shell 14 by fold lines 138 and
140. The opposite sides of front and rear wall panels 44 and 46 are
connected by fold lines 142 and 144 respectively to members 104 and
106 which combine to provide the side panel 50.
The blank 120 may be assembled by folding the inner shell along
fold lines 138, 140, 142 and 144 and adhering together members 104
and 106 in overlapping relation. Inner shell 14 may then be folded
on fold line 102 and the outer shell 12 folded on fold lines 122
and 124 to wrap shell 12 about inner shell 14. Members 28 and 30
can then be folded into overlapping relation and adhered together
to complete assembly of outer shell 12 and about inner shell
14.
It will be apparent to those skilled in the art that various
modifications and variations could be made in the packages and
blanks of this invention without departure from the basic concepts
of the invention.
