Description
- This application claims the benefit of U.S. Provisional Application No. 60/119,392 filed Feb. 10, 1999.
- 1. Field of the Invention
- The present invention pertains to containers and boxes used for packaging, shipping, and displaying goods. More particularly, the invention relates to display containers having means to facilitate the stacking of such containers on top of one another.
- 2. Description of the Related Art
- Display containers are widely used for shipping and marketing products. Such containers are especially popular in warehouse-type marketing settings and supermarkets where many containers are opened to display the food or merchandise within and stacked one on top of another. Examples include containers of packaged candy which may be decorated for display purposes. The containers of candy are shipped to the store in stacked form. Store personnel remove any display panels to allow the candy within to be seen and removed, and the containers are then stacked one on top of another on the retail floor.
- A major problem with previous known display containers is their lack of strength for stacking. All too often loaded and stacked containers collapse under the weight or become misshaped. This impairs the aesthetic appearance of the display sought by the seller and damages the products within.
- Typical containers are made from a die cut piece of single layer corrugated paperboard. Such construction has proven unsatisfactory for display use where removal of the top and any display cutout weakens the container sidewalls which bear the weight of a stacked group of containers. Collapse and/or warping results.
- Methods of producing stronger containers are known. For example, double walled corrugated containers are stronger than single walled corrugated containers. This added strength, however, adds additional manufacturing costs and creates more waste product for eventual disposal. Moreover, because the container is formed from a single die cut piece of corrugated paperboard, all parts of the container will be made of the double layer board, including the bottom forming panels which do not always need the added strength. This wastes natural resources consumed to make the container and adds unnecessary manufacturing costs.
- Accordingly, one object of the present invention is to provide a stronger display-ready container.
- Another object is to provide a stronger container that is economical to produce.
- A further object of the present invention is to provide a stronger container that is easy to assemble and use.
- Another object is to provide a container that can be safely stacked during shipping and display.
- A still further object is to provide a stronger stackable container that is assembleable from a knockdown state.
- Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned from making and using the invention. The objects and advantages of the invention may be realized and attained by means of the combinations pointed out in the appended claims.
- The objects and advantages of the present invention are obtained by providing a container having a corner support. The container includes first, second, third and fourth wall panels which have an inner face and a top edge. The first and second wall panels are attached to one another at a first corner, the second and third wall panels are attached to one another at a second corner, the third and fourth wall panels are attached to one another at a third corner, and the first and fourth wall panels are attached to one another at a fourth corner. A glue panel is attached to the inner face of the first wall panel, and a second glue panel is attached to the inner face of the second wall panel. The corner support include first and second panel sections adjacent the first corner for increasing the stacking strength. The first panel section has a first edge attached pivotally and integrally to the glue panel and has a second edge opposite the first edge. The second panel section has a first edge pivotally attached to the second glue panel and a second edge opposite the first edge which is attached pivotally and integrally to the second edge of the first panel section. This provides an additional support in the corner of the container, preferably spaced from the corner of the container, to provide additional support for containers stacked on top.
- The first and second panel sections can be configured for use with a container that has a knockdown state. Here the first and second panel sections move automatically into their desired positions upon assembly of the knockdown into the final container form.
- The foregoing summary and the following detailed description may be better understood when read in conjunction with the accompanying drawings. Various embodiments are shown for the purpose of illustrating the invention. It is understood, however, that this invention is not limited to the precise arrangements shown.

- The invention disclosed herein is for a container having a novel means of strengthening for stacking. Described below are preferred embodiments particularly suited for display-ready containers. It is recognized, however, that the present invention is adaptable to containers used for other purposes.
- Illustrated with reference to FIGS. 1, 2,3, and 4 is a display
ready container 10 for shipping and displaying goods. Thecontainer 10 hasmultiple wall panels 12 integrally attached to one another to form the container sides. Eachwall panel 12 has atop end 14 and abottom end 16 and aninner face 17 as shown. In this particular example themultiple wall panels 12 include afirst wall panel 18, asecond wall panel 20, athird wall panel 22, and afourth wall panel 24. Thesecond wall panel 20 is formed from twopartial panels - The first and
second wall panels first corner 26; the second andthird wall panels second corner 28; the third andfourth wall panels third corner 30; and the fourth andfirst wall panels fourth corner 32. - A
divider wall 34 is integrally attached to an end of thepartial wall panel 20 a and adhesively attached to thefourth wall panel 24 to divide thecontainer 10 into two sections as shown. Twodisplay openings 36 provide visual display and access to the two sections formed by thedivider wall 34. - Integrally attached along the
bottom end 16 of theside wall panels 12 is a bottom formed by multiple bottom flaps 38. Partial bottom flaps 38 a and 38 b integrally attached topartial wall panels bottom flap 38 attached to the wall panel 20 (See FIG. 6). Many different types of container bottoms are known in the art, any suitable bottom may be used. - As best illustrated in FIGS. 1, 2,3, and 4, corner supports 40 are provided adjacent each
corner corners container 10 are shown with acorner support 40, it is readily understood that other embodiments having less than all corners reinforced are possible. - Multiple configurations for the corner supports40 are contemplated, two particular preferred configurations being illustrated: a substantially
non-rectangular corner support rectangular corner support container 10 has a knockdown or collapsedstate 80 as seen in FIGS. 5A and 5B ideal for shipping stacked empty containers. The particular corner supports 42 a, 42 b, 44 a, 44 b are preferred for this type ofcontainer 10 since they automatically extend into the positions shown in FIG. 1 upon assembly of the container from the knockdown state. This feature is discussed below with further description of the corner supports 40. - With reference to FIGS. 1 and 3, the
corner support 40 of thenon-rectangular type first panel section 50 having afirst edge 52 attached pivotally to theinner face 17 of thefirst wall panel 18 between the first andfourth corners first edge 52 is attached pivotally to theinner face 17 by aglue panel 54 which is adhesively attached to theinner face 17 of thefirst wall panel 18, preferably with an adhesive. Theglue panel 54 is integrally attached to thetop end 14 of thefirst wall panel 18 and folded thereover onto theinner face 17 of thewall panel 18 and adhesively attached thereto with glue. Thefirst panel section 50 of this embodiment is thus formed as an integral extension of theglue panel 54. Thefirst panel section 50 further has asecond edge 56 which is opposite thefirst edge 52. - A
second panel section 58 has afirst edge 60 attached pivotally to theinner face 17 of thesecond wall panel 20 between the first andsecond corners first panel section 50, thesecond panel section 58 is attached pivotally to theinner face 17 through asecond glue panel 62 which is adhesively attached to thewall panel 20. Thesecond panel section 58 further has asecond edge 64 opposite thefirst edge 60 and attached pivotally to and contiguous with thesecond edge 56 of thefirst panel section 50. As best seen in FIG. 3, thefirst panel section 50, thesecond panel section 58, and thesecond glue panel 62 are integrally connected to one another and formed as an integral extension from thefirst glue panel 54. This integral unit has anend 66 as shown. Foldlines 68, such as a line of perforations or a score, delineate the ends of thepanel sections internal support corners longitudinal fold lines 68 to delineate the various contiguous panels, i.e. theglue panel 54, thefirst panel section 50, thesecond panel section 58, and thesecond glue panel 66. - Preferably, the
top edge 70 of bothpanel sections top end 14 of thewall panels panel sections wall panels - The
first glue panel 54 can take the form of a reinforcing panel covering a substantial portion of theinner face 17 of thefront wall panel 18 as shown in the figures. Such reinforcing is disclosed, for example, in U.S. Pat. No. 3,731,873 which is hereby incorporated by reference. While such a large reinforcing panel offers added strength and works well with the illustrated embodiment, it is not required. Theglue panel 54 could be smaller in width, although a suitable width for adequate gluing and strength should be maintained, e.g., the width of thesecond glue panel 62. - The
top end 14, where at thefirst glue panel 54 is integrally attached to thefirst wall panel 18, can be uncut as shown at 72, or cut as shown at 74 to reveal a cross section of both thewall panel 18 and glue panel 54 (both being corrugated as shown). A benefit of thecut sections 74 is that the wider edge formed by the cut can provide additional support surfaces for a container stacked on top. - With reference to FIG. 3, it is seen that the width “W1” of the
first panel section 50 between thefirst edge 52 andsecond edge 56 along an outer face 76 (facing the corner 26) is less than the width “WW1” taken along theinner face 17 of thefirst wall panel 18 between thefirst edge 52 and thefirst corner 26. Likewise, the width “W2” of thesecond panel section 58 between thefirst edge 60 and thesecond edge 64 along theouter face 76 is less than the width “WW2” taken along theinner face 17 of thesecond wall panel 20 between thefirst edge 60 and thefirst corner 26. “W1” and “W2” are preferably substantially equal; “WW1” and “WW2” are likewise preferably substantially equal. Thepanel sections corner support 42 a (edge 56) is spaced fromrespective corners 26 as shown. - The
corner support 40 of therectangular type rectangular corner support 44 a has first andsecond panel sections first edges second edges first edge 52 a of thefirst panel section 50 a is attached pivotally to thefourth wall panel 24 between the third andfourth corners glue panel 54 a; thefirst edge 60 a of thesecond panel section 58 a is attached pivotally to thefirst wall panel 18 between the fourth andfirst corners second glue panel 62 a. Unlike the non-rectangular corner supports 42 a, 42 b, both of the first andsecond glue tabs top end 14 ofrespective wall panels top edge 70 of thepanel sections top end 14 of thewall panels individual panel sections fold lines 68. The length of thepanel sections wall panels 12, or shorter as illustrated bycorner support 44 b in FIG. 1. The rectangular corner supports 44 a, 44 b, unlike thenon-rectangular corners inner face 17 of thewall panels edges corner 32. This geometry is necessary for the knockdown state as further described below. - A further feature of the rectangular corner supports44 a, 44 b is a tapered down
shape 78 along the inside corner. This eliminates any sharp edges and prevents merchandise from getting caught on the corner edge when being dropped into thecontainer 10 during loading. - The
container 10 is preferably made from a unitary piece of single layer corrugated paperboard which is formed into a knockdown (collapsed)state 80 for easy stacking and shipment to the user. The term “knockdown” refers to the configuration of thecontainer 10 in a flat unassembled form shown in FIGS. 5A and 5B (FIG. 5 showing the knockdown partially opened). The knockdown 80 has a firstknockdown wall 82 and a secondknockdown wall 84 attached to one another at the first andthird corners knockdown wall 82 included the first andfourth wall panels knockdown wall 84 includes the second andthird wall panels knockdown wall 82. It is understood that the “substantially” same plane does not mean the exact same plane. Thedivider wall 34 is sandwiched between and substantially parallel to theknockdown walls - To assemble the knockdown80 into the display
ready container 10, the twoknockdown walls corners - Illustrated in FIG. 6 is a blank86 for forming the knockdown 80 and the
container 10. The blank 86 is preferably a unitary piece of material such as single layer corrugated paperboard die cut to form the configuration shown. The view of FIG. 5 shows theinner face 17 of the integrally attachedwall panels divider wall 34 has an integrally connected reinforcingpanel 34 a having aglue tab 34 b, and is attached to a reinforcingpanel 91 which folds over thetop end 14 to reinforcepanel 20 a. - For the
non-rectangular corner support 42 a, the first glue panel 54 (on the right side of the reinforcing panel 90), the first andsecond panel sections second glue panel 62 are defined by perforated fold lines 68. Thetop end 14 of thewall panels second panel sections second glue panels 62 is cut to allow pivotal movement about thefirst edge 52 of thefirst panel section 50. Thenon-rectangular corner support 42 b is likewise constructed. - The
rectangular corner support 44 a has afirst glue panel 54 a which, in this embodiment, is in the middle of the reinforcingpanel 90 which also serves as thefirst glue panel 54 for thenon-rectangular corner support 42 b on the left side of reinforcingpanel 90. The reinforcingpanel 90 also hasdisplay openings 36 b conforming to displayopenings 36 on thefourth wall panel 24 to align therewith when folded about thetop end 14. Viewing thecorner support 44 a, thefirst panel section 50 a is integrally connected and separated by aperforated fold line 68 from thefirst glue panel 54 a, followed by thesecond panel section 58 a, in turn followed by thesecond glue panel 62 a which here also serves as thefirst glue panel 62 for thenon-rectangular corner support 42 a. The reinforcingpanel 90 is a single piece that forms the various panels for the non-rectangular corner supports 42 a, 42 b and therectangular corner support 44 a. - The
rectangular corner support 44 b is formed on a reinforcingpanel 92 and has a slot 94 (cut out) which allows easy pop out of thecorner support 44 b during assembly from the knockdown 80 to thefinal container 10. Again, the present embodiment is shown with reinforcingpanels various glue panels - The blank86 can be assembled into the knockdown 80 and the
final container 10 as now described with reference to FIGS. 5, 6 and 7. With the blank 86 in a flat position as shown in FIG. 6, the reinforcingpanels divider reinforcing panel 34 a (with reinforcing panel 91) are folded about thetop end 14 and secured with glue to theinner face 17 of therespective wall panels divider panel 34. It is important not to glue thepanel sections panel sections second panel sections 58 andsecond glue panel 62 are folded 180° as shown about thesecond edge 64 of thesecond panel section 58. The second edges 64 are offset from thecorners outer face 79 of theglue panel 62, theglue tab area 96 ofwall panel 20 b, and theglue tab 34 b. - The
wall panel 20 a and divider panel 34 (with the reinforcing panels secured thereto) and thepartial bottom flap 38 a integrally attached thereto are then folded, all as a single flat unit about theline 98 as indicated (corner 26) onto the other panels (FIG. 7). Theglue tab 34 b of thedivider reinforcing panel 34 a is secured with the glue to thearea 100 between the twodisplay openings 36, and thesecond glue panel 62 ofcorner support 42 a attached to thewall panel 20 a. Thewall panels panel 92 secured thereto and respective bottom flaps 38 and 38 b are then folded as a flat unit about line 102 (corner 30) and theglue tab 96 is secured with the glue to the back side of thepartial wall 20 a and the bottompartial flap 38 b to partialbottom flap 38 a to form thecomplete wall panel 20 and respective bottom flap, and thesecond glue panel 62 of thenon-rectangular corner support 42 b is secured to thewall panel 22. This forms a knockdown 80 which can be opened and assembled into thecontainer 10 of FIG. 1. - With reference to FIG. 5, it is seen that the opening of the knockdown80 to form the
container 10 automatically extends the corner supports of bothtypes second panel sections knockdown walls corner 26 goes from 0° (knockdown) to 90° (FIG. 1), thepanel sections first corner 26 to form the polygon shape as seen in FIG. 1. - With respect to the
rectangular corner support 44 a, it is seen that in theknockdown state 80, the twopanel sections knockdown walls panel sections 50 aand 58 a extend into the position shown in FIG. 4, extended from the corner and forming the rectangular shape as shown. - Illustrated in FIGS. 8 and 9 is another embodiment of the corner supports40 of the non-rectangular type. A
corner support 42 c is similar to that of thesupport 42 a of FIG. 3, with similar elements being referenced with the same reference number. The height of the first andsecond panel sections corner support 42 c are substantially less than the height of theadjacent wall panels corner support 42 c having alower end 59 as shown. Thefirst edge 52 of thefirst panel section 50 is attached pivotally to theinner face 17 of thefirst wall panel 18 via theglue panel 54 in a like manner as shown and described with reference to FIG. 3. Here, however, theglue panel 54 has alower section 104 that extends below thelower end 59 of thecorner support 42 c to the corner 26 (see FIG. 9). Thefirst edge 60 of thesecond panel 58 is pivotally attached to theinner face 17 of thesecond wall panel 20 via thesecond glue panel 62. The reinforcingpanel 91, folded over at thetop end 14 and glued to thepanel 20 has alower section 106 that extends below thelower end 59 of thecorner support 42 c to the corner 26 (see FIG. 9). - With reference to FIG. 9, it is seen that the
corner support 42 c is formed and cut from the first glue panel 54 (here a reinforcing panel) and reinforcingpanel 91 by makinghorizontal cuts 108, 108 b (thecut 108 b forming thelower end 59 of thecorner support 42 c) and a vertical cut 110 (forming the end 66) to leave a cut-out 112. - The container is formed into the knockdown state in a manner similar to that described with reference to FIGS. 6 and 7. It is believed that the
non-rectangular corner support 42 c, although less in height that thesupport corners - While particular embodiments of the invention are described herein, it is not intended to limit the invention to such disclosure. Changes and modifications may be incorporated and embodied within the scope of the appended claims. Moreover, the designation of “first,” “second,” etc., for the various panels and members is not limited to the particular panels or members shown herein.
