Description
77-~0 The present invention relates to a container and in particular, relates to one-piece corrugated containers.
The container art field is an old one and as such, many different containers have been developed,--many with a specific end use. One particular market for containers is ln the "fruit basket" field. These containers, generally~of a four to six quart size, have enjoyed extensive use for the pack-aging and marketing of fresh product as well as other commodi-~ties. These containers were inqtially formed of a corrugated paper board or card board materiaI to whiah was added a wood~
veneer rim with a wood handle; the assembly of the containers was generally by hand.
Subsequently, various improvements permitted elimin-; ation, in some instances, of the veneer rim. However, wood inserts were often employed for reinforcement and in the handle to provide a Gatisfactory container. Attempts~have been made to eliminate the expense and inconvenience of a separate handle.
,.l,!~ ,' However, such designs have usoally required the u~ge of closures i~` and/or reinforcing tape which has made the designs too expensive to compete on the marketplace.
Apart from the above, such containers have sufferedfrom other disadvantages. Thus, the handle assemblies have -~ generally been obtrusive and have increased the volume of ship-ping space above that which would ordinarily be required for the produce. Furthermore, the handle assemblies have generally been of a round configuration making shipment of the containers difficult.
~; ~ It lS an object of the present invention to provide a -.... :

77~
container handle assembly which handle assembly may be p]aced in a lay-flat condition during shipment and which is self-locking both during shipment and duri.ng use while carrying.
It is a further object of the present invention to provi.de a container capable of being manufactured from a corru-gated paper board/card board material, the container having an integral handle being manufactured from a one-piece blank with-out requiring reinforcement with other materials.
In a preferred embodiment of this invention there is provided, in a container having first and second opposed side walls and a handle, the improvement wherein said handle comprises first and second handle members associated with said first and second side walls respectively, each of said handle members being integral with at least a portion of the side wall. and foldable about a fold line along an edge thereof, each handle member having first and second sections divided by a fol.d line, said first section being adjacent said side wall, a hand carry-ing aperture in each of said first sections with one edge of the aperture bordering on said fold line between said first a~d second sections, one of said first sections having a tab member formed from at least a portion of the material removed from the aperture, said tab being hingedly connected along said fold line between said first and second sections.
In a further preferred embodiment there is provided a container comprising a one-piece corrugated paper hoard member, said container being of a rectangular configuration with a pair of opposed outer side walls and a pai~ of opposed inner side walls, each of said inner side walls being formed by half panels butting each other, a pai~ ot opposed end wal~s having ar inner ' and outer panel, with said inner panel being formed of a pair of half panels butting each other, corner reinforcement panels at each corner in juxtaposition to said inner side wa~ls, a plurality of apertures in said base, said corner reinforcing members having a tab portion extending therefrom adapted to en~age one of said apertures to lock the container in the desired configuration, and handle members extending from the ~;
side walls.
In still a further embodiment there is provided a blank of a paper board material for forming a container, said blank comprising a center panel having a desired length and width adapted to form the base or bottom of the container, said base panel being defined by first and second pairs of opposed fold lines, a pair of panels of a width equal to the width of the base panel extending from each of one pair of said fold lines to an outer margin of the blank and adapted to form the end walls of the container, a second pair of panels adapted to form the outer side walls of the container being of a length equal to the length of the base member and separated therefrom by said second pair of opposed fold lines, a further panel ~eing located at each of four corners of said blank, each panel being adjacent an end of said end wall panels, each panel having a-cat/fold line therein, and a pair of opposed handle panels.
In greater detail, the material of which the con-tainer is formed may be selected from any materials known to those skilled in the art. In the preferred embodiment, a corrugated fiberboard or solid fiberboard or cardboard or like material may be used it would ~e understood that the , `
term cardboard in the instant specification is embracive of all such materials. The particular strength and struc-ture of the material will depend on the required parameters of the assembled container and can be readily determined by those knowledgeable in this art.
The container is formed from a one-piece blank of the desired material, which blank is of a somewhat overall rectan~
gular configuration. Numerous fold lines and cut lines are used in the formation of the assembled container; the use of ~-such score and/or cut lines is well known to those skilled inthe art and accordingly, are not discussed herein.
The blank, through the use of the aforesaid old and cut lines, is divided into a number of panels including a central panel adapted to form the base or bottom of the ass-embled container. At opposed ends of the central panel are panels adapted to form the end walls and at opposed sides, panels adapted to form the side wall of the container. As previously mentioned, the container is o~ a double thickness except for the base. To this end, there is provided an inner side wall which is formed of two half sections butting at the midpoint of the outer side wall. At the outer four corners of the blank there are provided panels, a portion of which forms one half of an inner end wall thus giving the double end wall thickness; a further portion lies in juxtaposition to the inner wall thus giving a triple thickness at the corner. Also, this portion forming the triple thickness includes a tab member which is adapted to fit within apertures provided in the base panel to -lock the entire container together.
Intermediate the panels at the corners of the blank . ~- ' , ,' ', ' .- . :: .
`. ~ . ~ . . ,, , - ,--.' ~ .
1~77~0 are further panels adapted to form the handles of the container.
While these handles are particularly suitable for use with the container as described herein, they also may be used with other suitable type containers. As previously mentioned, the handles are integral with a side wall portion of the blank with each handle panel preferably comprising first and second sections.
The first section is of a width substantially equal to one half the width of the bottom panel such that the sections, when lying perpendicular to the side walls, will meet. Each handle panel includes a second section which may be folded upwardly to lie in juxtaposition to each other and perpendicular to the first sections.
Each of the first sections of the handle panels includes an aperture to provide a hand grip in the handle.
These apertures preferably extend substantially from the fold line between the first and second sections outwardly, within the first section of the panel. It is preferred that the panels be of a generally oval or eliptical configuration. In cutting the apertures, in one of the panels, the material is completely re-moved while in the second panel, the material is not removed butrather remains hinged to the panel along the fold line between the first and second sections. This material then forms a locking tab member for the handle assembly, both when used in its carrying mode and also when the handle is in a lay-flat con-dition for shipping.
The container as above-described is believed to possess substantial advantages over prior art containers. Thus, the container is of a one-piece structure of a single material with-i~77~ ~) out requiring the use of difFerent materials such as wood, plastic or the like either for reinforcement and/or for closure purposes. As such, the cost is significantly lower than such other containers which require rims and/or handles and/or closures or the like. The container has a handle assembly which folds flat during shipment and is self-locking to retain the lay-flat position. This self-locking, both in the shipping and carrying modes helps to prevent outward bowing of side panels. The handles are convenient in that they may be folded out of the way to allow unobstructed packing and unpacking and when folded, during shipment, provide a cushioning and clearance protection to the product. The folded handles maximize the capacity of the package for shipping. The container is of a double thickness construction throughout which provides maximum stacking strength for a plurality of containers and also pro-vides maximum puncture protection to the product.
Having thus generally descrihed the invention, refer-ence will be made to the accompanying drawings illustrating an embodiment thereof, in which:
FIGURE 1 is a plan view of a blank employed to form a container according to the invention;
FIGURE 2 is a perspective view of the sssembled container;
FIGURE 3 is a perspective view of the handle portion of the container of Figures 1 and 2 when the handles are arranged for carrying the container;
FIGURE 4 is a sectional view taken along the lines 4-4 of Figure 3;
., ~11)77~`0 FIGURE 5 is a cross-sectional view of the handle portion of the container when the handles are in a lay-flat condition for shipping; and FIGURE 6 is a cross-sectional view taken along the lines 6-6 of Figure 5.
Referring to the drawings in greater detail and by reference characters thereto, Figure 1 illustrates the blank used to form the assembled container and reference will now be made thereto.
As previously mentioned, the use of fold lines and/or cut lines and/or combinations of the same are well known in the art and accordingly, such lines will not be described in detail herein. In Figure 1, conventional fold lines are illustrated by a dashed line with the cut lines being illustrated by a solid line. A combination cut and fold line (i. e. spaced cuts with-in an otherwise conventional fold line) is illustrated by the darker and longer dashes.
Blank 10 has a somewhat overall rectangular configur-ation with certain cut-outs as will be discussed herein. Blank 10 is substantially symmetrical about its x and y axis and accor-dingly, reference herein will be made only to portions of the blank with the understanding that similar reference numerals with a prime indicate similar components on the other side of the x axis and reference numerals in the one hundreds will indi-cate similar components on the other side of the y axis.
As may be seen from Figure 1, the first pair of fold lines 12 and 12' extend across the width of the blank. Spaced interiorly from the sides of the blank and extending between ~ - 7 -~.. ,~ , , ' ' ~ ' ~' ' ~
~lQ7'7~I`O
and perpendicular to fold lines 12 and 12' are fold lines 14and 114. Fold lines 12, 12', 14 and 114 thus define a centre panel 16 which will constitute the base or bottom of the assembled container; the fold lines also define panels 18 and 118 which will constitute the end walls of the assembled con- `
:, tainer. ` .
Extending parallel to fold line 12 and spaced exter-iorly thereof is a further fold line 20 which extends across the width of the blank for a distance substantially equal to that portion of fold line 12 defining centre area 16. As may be ::~
seen from Figure 1, a cut line 22 extends from the intersection of fold lines 12 and 14 perpendicularly to fold line 12 to inter-sect foid line 20.
After intersection with fold line 20, cut line 22 :
angles slightly inwardly for a short distance as designated by reference numeral 24. It subsequently continues parallel to -its original direction for another short distance forming a tab portion generally designated by reference numeral 26. Subse- :
quently, a combination cut/fold line 28 forms an extension of , cut line 22 to the outer margin of blank 10.
A further cut line generally designated by reference ~ --numeral 30 is spaced inwardly of cut line 22 and cut/fold line 28, but parallel thereto and extends from fold line 20 to the outer margin or edge of the blank. A fold line 32 extends be-tween cut lines 22 and 30 parallel to fold line 20 at the term-ination of the angled portion 24 of cut line 22. Fold lines 32 and 20, along with cut lines 30 and 22, thus define an area generally designated by reference numeral 34.
.;~ 8 ~ . ... . .
~77~iD
~xtending from the change of cut line 22 to cut/fold line 28 and perpendicular thereto is a further cut line 36 to the outer side margin of the blank.
From the above, there is defined a rectangular panel 38 bounded by fold lines 12 and 20 and cut lines 22 and 122, which panel 38 is adapted to form the outer side wall of the assembled container. The inner side wall of the double thick-ness assembled container is formed of two panels, each extending one half of the length of side wall 38. As may be seen from Figure 1, a pair of panels 40 and 140 are defined by means of the cut and fold lines above-mentioned.
A further pair of panels are defined at each of the corners of the blank; referring to one corner, it will bè seen that there is a first panel 42 defined by cut line 36 and cut/
fold line 28 with a further panel 44. In this respect, it will be noted that panel 44 has on the outer marginal edge thereof a tab member generally designated by reference numeral 46. Simi-lar panels are formed àt all four extremities of the blank -panels 142, 144; 42', 44'; and 142', 144'.
Intermediate panels 44 and 142 is a panel forming one half of the handle assembly; the panel consists of a first sec-tion 48 adjacent fo]d line 20 and a second outer section 50 separated from first portion 48 by means of a fold line desig-nated by reference numeral 52. Within first section 48 is an aperture 54 which, as will be seen from Figure 1, has one portion thereof extending substantially along fold line 52.
The opposed handle panel consisting of sections 48' and 50' is substantially similar to that just described with the ,. g _ .
" , ~77`~`0 exception that, upon the cutting of aperture 54', the material is not removed but rather is left hinged along fold line 52' as shown in Figurec; 1 and 2 to form a tab 55 for reasons which will become apparent hereinafter.
The center panel area 16, adapted to form the base or bottom of the assembled container, has a plurality of apertures therein as shown in Figure 1 and designated by reference numerals 56, 156, S6' and 156'.
Reference may now be had to Figures 2 through 6 illus-trating the assembled container. To assemble the containerfrom the blank of Figure 1, end walls 18 and 118 are bent sub-substantially perpendicularly to base panel 16 about fold lines 14 and 114 respectively. Panels 40 and 140 are then folded about fold line 12 to be perpendicular to end wall panels 18 and 118 respectively; panels 40 and 140 are adapted to abut each other to thus form an interior side wall of the assembled con-tainer. Panels 40' and 140' are folded in a like manner.
Subsequently, panel 38 is folded upwardly about fold line 12 to form an outer side wall of the assembled container.
Following the formation of the outer side wall, panels 42 and 44 are then placed in position. In this regard, panel 44 is folded about fold lines 20 and 32 to lie in juxtaposition to panel 40 thus forming one half of an interior side wall. At the same time, panel 42 is bent 90 about cut/fold line 28 to lie in juxtaposition to the interior of end wall 18. In this respect, panel 42 is dimensioned so as to cover substantially one half the width of end wall 18 and will thus abut panel 42' when it is folded in the same manner. It will be noted that the distance . ..
11~77~0 between cut lines 20 and 32 is substantially equal to the thickness of the material used in the container such that por-tion 34 lies substantially on top of the thickness of panel 40 over which it is folded. Final]y, the container is locked and held in place by means of tab 46 engaging aperture 56. The other corners of the blank are similarly folded and locked in position.
The assembled container and the use thereof is illus-trated in Figures 2 through 6 and reference will now be made thereto.
The handle assembly, as illustrated in Figures 5 and 6, may be folded to a lay-flat condition. This presents substan-tial advantages in that they provide a-cushioning and clearance protection to the product while they minimize the cube of the package for shipping. Thus, as may be seen from Figures 5 and 6, a first handle panel consisting of sections 4~ and 50 is folded about fold line 20 to lie substantially perpendicular to side wall 38. Subsequently, th~ handle panel consisting of sections 48' and 50' is laid on top thereof with tab member 55 being inserted through aperture 54. Tab member 55 will then lie substantially in juxtaposition to the downwardly facing sur-face of section 50 to lock the handle panels together. Thus, as may clearly be seen, the handles are self-locking and can provide a cushioning effect to the goods packed within the con-tainer while at the same time minimizing the volume required for shipping the same.
When required, the handle members are adapted for carrying the container as shown in Figures 3 and 4. In this ~77~
arrangement, sections 50 and 50' are folded about fold lines 52 and 52' respectively to lie in juxtaposition to each other.
Subsequently, tab member 55 is inserted through aperture 54 as shown in Figure 4 to lock the handles in place for carrying.
It will be understood that changes and modifications may be made to the above-describea embodiment without departing from the spirit and scope of the invention. While it becomes evident from the description of the preferred embodiment that certain dimensioning ratios are preferred, they may be varied lo if desired. Thus, it is preferred that, for example, walls 40 and 140 but each other to provide a double thickness for the entire container. However, if so desired, modifications may be made to the particular arrangement shown. In the iliustrated embodiment, and as may clearly be seen from Figure 1, end wall 18 has a height a little greater than the height of side wall panel 40. This difference is generally equal to the thickness of the material employed such that when portion 34 is folded over panel 40, the heights of the walls are then equallized. Section 34 generally has a "width" equal to the thickness of the material.

The container art field is an old one and as such, many different containers have been developed,--many with a specific end use. One particular market for containers is ln the "fruit basket" field. These containers, generally~of a four to six quart size, have enjoyed extensive use for the pack-aging and marketing of fresh product as well as other commodi-~ties.

It is a further object of the present invention to provi.de a container capable of being manufactured from a corru-gated paper board/card board material, the container having an integral handle being manufactured from a one-piece blank with-out requiring reinforcement with other materials.
In a preferred embodiment of this invention there is provided, in a container having first and second opposed side walls and a handle, the improvement wherein said handle comprises first and second handle members associated with said first and second side walls respectively, each of said handle members being integral with at least a portion of the side wall. and foldable about a fold line along an edge thereof, each handle member having first and second sections divided by a fol.d line, said first section being adjacent said side wall, a hand carry-ing aperture in each of said first sections with one edge of the aperture bordering on said fold line between said first a~d second sections, one of said first sections having a tab member formed from at least a portion of the material removed from the aperture, said tab being hingedly connected along said fold line between said first and second sections.
In a further preferred embodiment there is provided a container comprising a one-piece corrugated paper hoard member, said container being of a rectangular configuration with a pair of opposed outer side walls and a pai~ of opposed inner side walls, each of said inner side walls being formed by half panels butting each other, a pai~ ot opposed end wal~s having ar inner ' and outer panel, with said inner panel being formed of a pair of half panels butting each other, corner reinforcement panels at each corner in juxtaposition to said inner side wa~ls, a plurality of apertures in said base, said corner reinforcing members having a tab portion extending therefrom adapted to en~age one of said apertures to lock the container in the desired configuration, and handle members extending from the ~;
side walls.
In still a further embodiment there is provided a blank of a paper board material for forming a container, said blank comprising a center panel having a desired length and width adapted to form the base or bottom of the container, said base panel being defined by first and second pairs of opposed fold lines, a pair of panels of a width equal to the width of the base panel extending from each of one pair of said fold lines to an outer margin of the blank and adapted to form the end walls of the container, a second pair of panels adapted to form the outer side walls of the container being of a length equal to the length of the base member and separated therefrom by said second pair of opposed fold lines, a further panel ~eing located at each of four corners of said blank, each panel being adjacent an end of said end wall panels, each panel having a-cat/fold line therein, and a pair of opposed handle panels.
In greater detail, the material of which the con-tainer is formed may be selected from any materials known to those skilled in the art. In the preferred embodiment, a corrugated fiberboard or solid fiberboard or cardboard or like material may be used it would ~e understood that the , `
term cardboard in the instant specification is embracive of all such materials. The particular strength and struc-ture of the material will depend on the required parameters of the assembled container and can be readily determined by those knowledgeable in this art.
The container is formed from a one-piece blank of the desired material, which blank is of a somewhat overall rectan~
gular configuration. Numerous fold lines and cut lines are used in the formation of the assembled container; the use of ~-such score and/or cut lines is well known to those skilled inthe art and accordingly, are not discussed herein.
The blank, through the use of the aforesaid old and cut lines, is divided into a number of panels including a central panel adapted to form the base or bottom of the ass-embled container. At opposed ends of the central panel are panels adapted to form the end walls and at opposed sides, panels adapted to form the side wall of the container. As previously mentioned, the container is o~ a double thickness except for the base. To this end, there is provided an inner side wall which is formed of two half sections butting at the midpoint of the outer side wall. At the outer four corners of the blank there are provided panels, a portion of which forms one half of an inner end wall thus giving the double end wall thickness; a further portion lies in juxtaposition to the inner wall thus giving a triple thickness at the corner. Also, this portion forming the triple thickness includes a tab member which is adapted to fit within apertures provided in the base panel to -lock the entire container together.

1~77~0 are further panels adapted to form the handles of the container.
While these handles are particularly suitable for use with the container as described herein, they also may be used with other suitable type containers. As previously mentioned, the handles are integral with a side wall portion of the blank with each handle panel preferably comprising first and second sections.
The first section is of a width substantially equal to one half the width of the bottom panel such that the sections, when lying perpendicular to the side walls, will meet. Each handle panel includes a second section which may be folded upwardly to lie in juxtaposition to each other and perpendicular to the first sections.
Each of the first sections of the handle panels includes an aperture to provide a hand grip in the handle.
These apertures preferably extend substantially from the fold line between the first and second sections outwardly, within the first section of the panel. It is preferred that the panels be of a generally oval or eliptical configuration. In cutting the apertures, in one of the panels, the material is completely re-moved while in the second panel, the material is not removed butrather remains hinged to the panel along the fold line between the first and second sections. This material then forms a locking tab member for the handle assembly, both when used in its carrying mode and also when the handle is in a lay-flat con-dition for shipping.
The container as above-described is believed to possess substantial advantages over prior art containers. Thus, the container is of a one-piece structure of a single material with-i~77~ ~) out requiring the use of difFerent materials such as wood, plastic or the like either for reinforcement and/or for closure purposes. As such, the cost is significantly lower than such other containers which require rims and/or handles and/or closures or the like. The container has a handle assembly which folds flat during shipment and is self-locking to retain the lay-flat position. This self-locking, both in the shipping and carrying modes helps to prevent outward bowing of side panels. The handles are convenient in that they may be folded out of the way to allow unobstructed packing and unpacking and when folded, during shipment, provide a cushioning and clearance protection to the product. The folded handles maximize the capacity of the package for shipping. The container is of a double thickness construction throughout which provides maximum stacking strength for a plurality of containers and also pro-vides maximum puncture protection to the product.

Referring to the drawings in greater detail and by reference characters thereto, Figure 1 illustrates the blank used to form the assembled container and reference will now be made thereto.
As previously mentioned, the use of fold lines and/or cut lines and/or combinations of the same are well known in the art and accordingly, such lines will not be described in detail herein. In Figure 1, conventional fold lines are illustrated by a dashed line with the cut lines being illustrated by a solid line. A combination cut and fold line (i. e. spaced cuts with-in an otherwise conventional fold line) is illustrated by the darker and longer dashes.
Blank 10 has a somewhat overall rectangular configur-ation with certain cut-outs as will be discussed herein. Blank 10 is substantially symmetrical about its x and y axis and accor-dingly, reference herein will be made only to portions of the blank with the understanding that similar reference numerals with a prime indicate similar components on the other side of the x axis and reference numerals in the one hundreds will indi-cate similar components on the other side of the y axis.
As may be seen from Figure 1, the first pair of fold lines 12 and 12' extend across the width of the blank. Spaced interiorly from the sides of the blank and extending between ~ - 7 -~.. ,~ , , ' ' ~ ' ~' ' ~

and perpendicular to fold lines 12 and 12' are fold lines 14and 114. Fold lines 12, 12', 14 and 114 thus define a centre panel 16 which will constitute the base or bottom of the assembled container; the fold lines also define panels 18 and 118 which will constitute the end walls of the assembled con- `

Extending parallel to fold line 12 and spaced exter-iorly thereof is a further fold line 20 which extends across the width of the blank for a distance substantially equal to that portion of fold line 12 defining centre area 16. As may be ::~
seen from Figure 1, a cut line 22 extends from the intersection of fold lines 12 and 14 perpendicularly to fold line 12 to inter-sect foid line 20.
After intersection with fold line 20, cut line 22 :
angles slightly inwardly for a short distance as designated by reference numeral 24. It subsequently continues parallel to -its original direction for another short distance forming a tab portion generally designated by reference numeral 26. Subse- :
quently, a combination cut/fold line 28 forms an extension of , cut line 22 to the outer margin of blank 10.
A further cut line generally designated by reference ~ --numeral 30 is spaced inwardly of cut line 22 and cut/fold line 28, but parallel thereto and extends from fold line 20 to the outer margin or edge of the blank. A fold line 32 extends be-tween cut lines 22 and 30 parallel to fold line 20 at the term-ination of the angled portion 24 of cut line 22. Fold lines 32 and 20, along with cut lines 30 and 22, thus define an area generally designated by reference numeral 34.

~xtending from the change of cut line 22 to cut/fold line 28 and perpendicular thereto is a further cut line 36 to the outer side margin of the blank.
From the above, there is defined a rectangular panel 38 bounded by fold lines 12 and 20 and cut lines 22 and 122, which panel 38 is adapted to form the outer side wall of the assembled container. The inner side wall of the double thick-ness assembled container is formed of two panels, each extending one half of the length of side wall 38. As may be seen from Figure 1, a pair of panels 40 and 140 are defined by means of the cut and fold lines above-mentioned.
A further pair of panels are defined at each of the corners of the blank; referring to one corner, it will bè seen that there is a first panel 42 defined by cut line 36 and cut/
fold line 28 with a further panel 44. In this respect, it will be noted that panel 44 has on the outer marginal edge thereof a tab member generally designated by reference numeral 46. Simi-lar panels are formed àt all four extremities of the blank -panels 142, 144; 42', 44'; and 142', 144'.
Intermediate panels 44 and 142 is a panel forming one half of the handle assembly; the panel consists of a first sec-tion 48 adjacent fo]d line 20 and a second outer section 50 separated from first portion 48 by means of a fold line desig-nated by reference numeral 52. Within first section 48 is an aperture 54 which, as will be seen from Figure 1, has one portion thereof extending substantially along fold line 52.
The opposed handle panel consisting of sections 48' and 50' is substantially similar to that just described with the ,. g _ .
" , ~77`~`0 exception that, upon the cutting of aperture 54', the material is not removed but rather is left hinged along fold line 52' as shown in Figurec; 1 and 2 to form a tab 55 for reasons which will become apparent hereinafter.
The center panel area 16, adapted to form the base or bottom of the assembled container, has a plurality of apertures therein as shown in Figure 1 and designated by reference numerals 56, 156, S6' and 156'.
Reference may now be had to Figures 2 through 6 illus-trating the assembled container. To assemble the containerfrom the blank of Figure 1, end walls 18 and 118 are bent sub-substantially perpendicularly to base panel 16 about fold lines 14 and 114 respectively. Panels 40 and 140 are then folded about fold line 12 to be perpendicular to end wall panels 18 and 118 respectively; panels 40 and 140 are adapted to abut each other to thus form an interior side wall of the assembled con-tainer. Panels 40' and 140' are folded in a like manner.
Subsequently, panel 38 is folded upwardly about fold line 12 to form an outer side wall of the assembled container.
Following the formation of the outer side wall, panels 42 and 44 are then placed in position. In this regard, panel 44 is folded about fold lines 20 and 32 to lie in juxtaposition to panel 40 thus forming one half of an interior side wall. At the same time, panel 42 is bent 90 about cut/fold line 28 to lie in juxtaposition to the interior of end wall 18. In this respect, panel 42 is dimensioned so as to cover substantially one half the width of end wall 18 and will thus abut panel 42' when it is folded in the same manner. It will be noted that the distance . ..
11~77~0 between cut lines 20 and 32 is substantially equal to the thickness of the material used in the container such that por-tion 34 lies substantially on top of the thickness of panel 40 over which it is folded. Final]y, the container is locked and held in place by means of tab 46 engaging aperture 56. The other corners of the blank are similarly folded and locked in position.
The assembled container and the use thereof is illus-trated in Figures 2 through 6 and reference will now be made thereto.
The handle assembly, as illustrated in Figures 5 and 6, may be folded to a lay-flat condition. This presents substan-tial advantages in that they provide a-cushioning and clearance protection to the product while they minimize the cube of the package for shipping. Thus, as may be seen from Figures 5 and 6, a first handle panel consisting of sections 4~ and 50 is folded about fold line 20 to lie substantially perpendicular to side wall 38. Subsequently, th~ handle panel consisting of sections 48' and 50' is laid on top thereof with tab member 55 being inserted through aperture 54. Tab member 55 will then lie substantially in juxtaposition to the downwardly facing sur-face of section 50 to lock the handle panels together. Thus, as may clearly be seen, the handles are self-locking and can provide a cushioning effect to the goods packed within the con-tainer while at the same time minimizing the volume required for shipping the same.
When required, the handle members are adapted for carrying the container as shown in Figures 3 and 4. In this ~77~
arrangement, sections 50 and 50' are folded about fold lines 52 and 52' respectively to lie in juxtaposition to each other.
Subsequently, tab member 55 is inserted through aperture 54 as shown in Figure 4 to lock the handles in place for carrying.
It will be understood that changes and modifications may be made to the above-describea embodiment without departing from the spirit and scope of the invention. While it becomes evident from the description of the preferred embodiment that certain dimensioning ratios are preferred, they may be varied lo if desired. Thus, it is preferred that, for example, walls 40 and 140 but each other to provide a double thickness for the entire container. However, if so desired, modifications may be made to the particular arrangement shown. In the iliustrated embodiment, and as may clearly be seen from Figure 1, end wall 18 has a height a little greater than the height of side wall panel 40. This difference is generally equal to the thickness of the material employed such that when portion 34 is folded over panel 40, the heights of the walls are then equallized. Section 34 generally has a "width" equal to the thickness of the material.
