In another embodiment, top closure panels (100) are provided to close off the upper portions of the container.
Description
- This application is a Continuation of prior Application Ser. No. 10/155,468, filed May 23, 2002, which is a reissue patent application of U.S. Pat. No. 6,296,178, priority from the filing date of which is hereby claimed under 35 U.S.C. § 120. Prior Application Ser. No. 10/155,468 is hereby incorporated by reference.
- The present invention relates to corrugated paperboard containers, and more particularly, to single-piece container blanks capable of forming triangular reinforcing columns within the container's interior as assembled.
- Containers used to package perishable items, such as fruits and vegetables, must meet a variety of requirements. One important requirement is that the container be strong enough to contain the product from the time it is packed until the time it is unpacked. It is also important that the container have sufficient stacking strength so that several containers may be stacked vertically during shipment. Another desirable feature for efficient transportation is to have stacking tabs protruding from one container and insertable into an opening of adjacent container to prevent sway and possible destacking. See for example, U.S. Pat. No. 3,940,053.
- One known method of gaining additional container strength is to use some type of triangular corner post within the container. See for example, U.S. Pat. No. 5,535,941. Typically, such arrangements have complicated blanks, are difficult to form, or require excessive gluing in order to maintain their shape. These can all be significant disadvantages for container makers, since additional effort is needed to cut and create the finished boxes, thereby adding to their production cost.
- The present invention is directed to providing a single-piece containerboard blank from which a box is easily formed and maintained. The present invention includes an arrangement in which the various box panels naturally correspond to keep their relative positions, thus ensuring good container strength throughout the container's use. The present invention may be made with various stacking tabs to improve its stack-ability, as well.
- In accordance with aspects of the present invention, a single-piece containerboard blank is provided having hingedly connected first and second side walls in which the second side wall is smaller in length than the first side wall. The second side walls include outer abutment edges. The first side walls include first and second interior end walls. Each second interior end wall includes a hypotenuse panel with an inwardly-oriented edge. As assembled, the blank forms a container having opposed multi-ply side panels, opposed end panels, and a bottom panel. The hypotenuse panels are oriented in an upright manner and ultimately positioned so that their inwardly-oriented edges push against the first side wall, and in one embodiment, further push directly against the abutment edges of the second side wall.
- In accordance with other aspects of the invention, tabs and mating openings are provided to help stabilize the container when multiple containers are placed in a stack. In another embodiment, top closure panels are provided to close off the upper portions of the container. The top closure panels may each include a notch that mates with an upright tab as assembled.
- The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
- FIG. 1 is a plan view of one embodiment of a box blank formed in accordance with the present invention;
- FIG. 2 is a perspective view of the embodiment of FIG. 1, as partially assembled;
- FIG. 3 is a perspective view of the embodiment of FIG. 1, as further partially assembled;
- FIG. 4 is a perspective view of the embodiment of FIG. 1, as assembled;
- FIG. 5 is a plan view of a second embodiment of a box blank formed in accordance with the present invention;
- FIG. 6 is a perspective view of the embodiment of FIG. 5, as assembled; and
- FIG. 7 is one embodiment of glue lines that may be used in the present invention.
- Referring now to the drawings, the several separate and distinct panels comprising the container blank, generally depicted at10, will be described. It is to be noted that the container blank 10 is comprised of a single-piece of containerboard material such as are known to those of skill in the art, e.g., double-faced corrugated medium or the like. The central portion of the container blank 10 is a
bottom panel 12 which forms the bottom of the erected container. Thebottom panel 12 is generally in the shape of a rectangle as is customary, although other planar configurations are within the scope of the present invention. - For the purpose of further description herein, the longitudinal direction is defined as the direction along the longer dimension of the bottom panel, and the transverse direction is defined as the direction along the shorter dimension of the bottom panel.
- Referring particularly to FIG. 1,
end walls transverse hinge lines 18, 20. In the erected state, theend walls - Extending outwardly in the transverse direction are side panels generally indicated at22 and 24. Each side panel includes a
first side wall 26 extending outwardly from each longitudinal edge of the bottom panel and connecting thereto along a firstlongitudinal hinge line 30. Thefirst side walls 26 form the outer wall in each of the side panels. - The side panels also include
second side walls 34. Onesecond side wall 34 extends outwardly from eachfirst side wall 26 and is connected thereto along a secondlongitudinal hinge line 38. As the purpose will be made clear in the following description, eachsecond side wall 34 is of a longitudinal length that is less than the longitudinal length of its correspondingfirst side wall 26. The transverse end edges of these shorter,second side walls 34 formabutment edges 42. - Still referring to FIG. 1, the ends of the
first side walls 26 include first and secondinterior end walls end walls interior end walls 50 extend longitudinally outward from the transverse edges of thefirst side walls 26 and are connected thereto along secondtransverse hinge lines 54. The first and secondtransverse hinge lines - A second interior end wall extends transversely outward from the outer edge of each first
interior end wall 50 and connects thereto along a thirdlongitudinal hinge line 60. Each secondinterior end wall 52 has ahypotenuse panel 62 that extends longitudinally inward toward theabutment edge 42 of the adjacentsecond side wall 34. Thehypotenuse panel 62 has an inwardly-orientededge 66 and is connected to the secondinterior end wall 52 along a thirdtransverse hinge line 70. As shown best in FIG. 1, the thirdtransverse hinge line 70 is located outward of the secondtransverse hinge line 54 and parallel thereto. - The transverse dimension of the first and second
interior end walls - It should be appreciated by those skilled in the art that the present container blank10 can be erected on suitable automatic machinery such as a modified tray former. Likewise, the blank 10 can be erected manually through appropriate folding. Prior to folding, an adhesive is applied to the container blank 10, as appropriate. See FIG. 7 for one embodiment of adhesive lines that may be used in the present invention. Adhesive lines are designated collectively as
elements 80 in FIG. 7. (Variousoptional openings 82 are shown as well.) It should be understood that FIG. 7 is illustrative and not limiting to the present invention. Other configurations of adhesive sizes, shapes, numbers of applications, or placements may be used as would be understood by one of ordinary skill in the art. An example adhesive may be a suitable hot melt which could be applied through automatic applying means known to those skilled in the art, or other known adhesive. - As shown in FIG. 2, the first step in forming the container is to fold the second
interior end walls 52 over 180° along the thirdlongitudinal hinge lines 60 such that the secondinterior end walls 52 are positioned against the firstinterior end walls 50. Likewise, thesecond side walls 34 are folded along the secondlongitudinal line 38 180° over onto their correspondingfirst side walls 26. The combination first and secondinterior end walls - In doing this, the
hypotenuse panel 62 will interfere with thefirst side wall 26, since thehypotenuse panel 62 folds about the thirdtransverse hinge line 70 which is outward of the secondtransverse hinge line 54 and since the hypotenuse inwardly-orientededge 66 is inward of the secondtransverse hinge line 54. Thus, in order to form the 90° orientation, thehypotenuse panel 62 must be pushed upward and away from the firstinterior end wall 50. In doing so, the inwardly-orientedhypotenuse edge 66 will rest against thefirst side wall 34 and preferably against the second sidewall abutment edge 42. In designing a particular container, thesecond side wall 34,hypotenuse panel 62, and various transverse hinge lines are preferably dimensioned so that the hypotenuse inwardly-oriented edge is contained by theabutment edge 42. - Continuing construction to FIG. 3, the combination of end and side walls are folded along the first longitudinal hinge lines30. Lastly, the
end walls interior end wall 50. Variations in formation may be made. For example, the end walls may be inserted between the first and second interior end walls by varying the forming steps. What is important is the formation of triangular corner posts using the hypotenuse panel. Because this panel is folded from the second interior end wall, it has a tendency to push against the first side wall. In one embodiment, the tolerance between the abutment edge and the inwardly-oriented edge are small enough so that the hypotenuse panel is effectively trapped by the abutment edge and cannot move further inward into the container. - Referring to FIG. 1, the blank may optionally include a number of
cutouts 90 along the secondlongitudinal hinge line 38. As assembled, the remaining portions form a number ofupright tabs 92.Openings 96 formed along the firstlongitudinal hinge line 30 provide corresponding apertures within which the tabs may be inserted when multiple containers are vertically stacked. Theopenings 96 are thus located and sized to accept an upright tab. As will be appreciated by the above, a plurality of vertically stacked erected containers are relatively stable because the stacking tabs tend to lock the stacked containers together. In this regard, the multiple ply of the side panels provide additional stacking strength as well. - Referring to FIGS. 5 and 6, the blank10 may further optionally include
top closure panels 100 connected to the end panels along fourth transverse hinge lines 102. There are numerous types of top closure panels that may be used. The ones shown in FIGS. 5 and 6 cover only a portion of the container as assembled and includenotches 104 that mate with theupright tabs 92 for further stability and ease of alignment. - It will be appreciated by those skilled in the container art, the present invention provides an easily-formed and easily-assembled produce container from a single-piece containerboard material. The assembled container includes triangular corner posts that provide enhanced strength and stacking capability. The triangular corner posts are formed in a manner that encourages their proper placement, thus reducing the complexity of the box and the amount of adhesive required. The multi-ply side panels also provide enhanced construction and stacking strength.
- While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. All such modifications are intended to be included within the scope of the appended claims. For example, depending on the packing and transportation requirements, the end panel construction may be made of multiple plies. Or, for example, numerous types of lids or covers may be used.
