Description
TRANSIT PACKAGING HAVING REDUCED CONTENT
Field of the Invention This invention relates to transit packaging having a reduced content. In particular, this invention relates to transit packaging for straight walled containers, namely aluminum containers, steel containers or other containers for tinned goods shipped in a multi-pack format.
Background of the Invention Straight walled containers, such as aluminum containers, steel containers and other containers for tinned goods are widely used in the food industry. In particular, tinned soups, vegetables, juices and soft drinks are currently packaged in straight walled aluminum or steel containers. These containers must be packaged in a multi-pack format for efficient shipping. The multi-pack format requires outer packing support for loading onto pallets.
Full corrugated boxes or shrink wrapped units are generally used to package straight walled containers for transit. Full corrugated boxes are excessively wasteful of cardboard. There is an ongoing trend to reduce total packaging content by at least 10%.
Currently, two U.S. states have enacted laws requiring 10% packaging reductions. Replacing the corrugated boxes with trays on which the containers are nested and then shrink wrapped reduces the packaging but creates problems regarding the structural integrity of the trays.
In particular, shrink wrapped trays lack horizontal or lateral stability when piled onto pallets for shipping. The resulting unstable pallet loads are prone to a high rate of damage during transit.
In addition, shrink wrapping is not energy efficient. Extensive energy is required to heat the wrap, most of which is lost to the ambient surroundings.
U.S. Patent Nos. 3,826,357 and 4,998,615 are examples of packaging which addresses the structural problem. Dividers or stackers elements are added in order to improve the stability of the packages. The necessity of dividers and stacker elements precludes any significant reduction in packaging.
Canadian Patent No. 1,191,819 describes a multi-package assembly. The packages are sandwiched between two sheets of cardboard and held together by strips of frangible adhesive. This type of packaging results in reduced packaging.
However, this packaging does not provide lateral structural integrity sufficient to prevent sideways shifting of packages loaded onto a pallet.

Although several embodiments are illustrated, like reference numbers refer to like parts of the figures.
Detailed Description of the Drawings In a first embodiment illustrated in Figures 1-3, the packaging 10 comprises a blank 12 having a central panel 14 and two side panels 16, 18 secured about a plurality of containers 36 by a strap 26. Strap 26 is preferably a polyethylene strap conventionally used in the packaging industry.
Referring to Figure 2, the blank 12 is illustrated in an unfolded condition.
Central panel 14 is generally rectangular having a longitudinal extent and a lateral extent.
Panel 14 is separated from side panel 16 by longitudinally extending score 20, and from side panel 18 by longitudinally extending score 22. Scores 20 and 22 are applied in a conventional manner.
Blank 12 is preferably made from a cardboard, corrugated cardboard or paper board material. The longitudinal direction corresponds with the longitudinal grain of the material. In the case of corrugated cardboard, the direction of the flutes is the longitudinal direction.
Side panels 16, 18 have aligned notches 24 at each end thereof and equally spaced from the scores 20 and 22. The distance between scores 20, 22 and the outer edges 38, 40 of side panels 16, 18 is such that the side panels 16, 18 have a height when folded downwards less than the height of containers 36.
The blank 12 has a container retaining region comprising a regular pattern of footprints 27. Each footprint 28 has an aperture 28, a concentric circular score 34 and a plurality of tabs 30 formed by die cuts 32. The tabs 30 radiate inwardly from a circular score 34. The die cuts 32 and circular score 34 are applied in a conventional manner.
The footprints 27 are arranged about the central panel in a regular pattern which will space the containers 36 in a side by side relation. Although the preferred embodiment illustrates a regular "5" pattern, other efficient patterns are also contemplated by the present invention.
Containers 36 are like containers, such as beer, soft drinks and juices. The containers 36 are generally characterized by a two piece construction comprising a flat top 42 and a cup shaped bottom 44. The bottom 44 has straight sides and joins the top 42 at a lip 46.
In use, the containers 36 are arranged in the regular side by side pattern.
The blank 12 is placed over the containers 36 such that the footprints 27 overlay the tops 42 of the containers. The blank 12 is then moved relative to the containers 36 to engage the containers 36 with a respective footprint 27. The tops 42 of container 36 will be thrust through the apertures 28. Tabs 30 will be thrust outwardly and upwardly to engage the bottom rim of lip 46. In this condition, tabs 30 are biased to retain the containers in engagement with the blank 12. The side panels 16, 18 are plowed downwardly, folding at scores 20 and 22.
Figure 3 more specifically illustrates the engagement of the tabs 30 with the bottom rim of the lip 46. As shown, the tabs 30 are bent upwardly from circular score 34.
The inner edges of tabs 30 are forced over lip 46 and are resiliently urged against and biased towards the sides of container 36 thereby engaging lip 46. The relative sizing of the circular score 34 and length of the tabs 30 should be of sufficient length to ensure full engagement of the tabs 30 with the lip 46.
Side panels 16, 18 have aligned notches 24 at each end thereof and equally spaced from the scores 20 and 22. The distance between scores 20, 22 and the outer edges 38, 40 of side panels 16, 18 is such that the side panels 16, 18 have a height when folded downwards less than the height of containers 36.
The blank 12 has a container retaining region comprising a regular pattern of footprints 27. Each footprint 28 has an aperture 28, a concentric circular score 34 and a plurality of tabs 30 formed by die cuts 32. The tabs 30 radiate inwardly from a circular score 34. The die cuts 32 and circular score 34 are applied in a conventional manner.
The footprints 27 are arranged about the central panel in a regular pattern which will space the containers 36 in a side by side relation. Although the preferred embodiment illustrates a regular "5" pattern, other efficient patterns are also contemplated by the present invention.
Containers 36 are like containers, such as beer, soft drinks and juices. The containers 36 are generally characterized by a two piece construction comprising a flat top 42 and a cup shaped bottom 44. The bottom 44 has straight sides and joins the top 42 at a lip 46.
In use, the containers 36 are arranged in the regular side by side pattern.
The blank 12 is placed over the containers 36 such that the footprints 27 overlay the tops 42 of the containers. The blank 12 is then moved relative to the containers 36 to engage the containers 36 with a respective footprint 27. The tops 42 of container 36 will be thrust through the apertures 28. Tabs 30 will be thrust outwardly and upwardly to engage the bottom rim of lip 46. In this condition, tabs 30 are biased to retain the containers in engagement with the blank 12. The side panels 16, 18 are plowed downwardly, folding at scores 20 and 22.
Figure 3 more specifically illustrates the engagement of the tabs 30 with the bottom rim of the lip 46. As shown, the tabs 30 are bent upwardly from circular score 34.
The inner edges of tabs 30 are forced over lip 46 and are resiliently urged against and biased towards the sides of container 36 thereby engaging lip 46. The relative sizing of the circular score 34 and length of the tabs 30 should be of sufficient length to ensure full engagement of the tabs 30 with the lip 46.
Strap 26 is then wrapped about the containers 36 and blank 12, and positioned to rest in aligned notches 24. Strap 26 is firmly tightened to retain containers 36 together, while blank 12 provides lateral stability, thus forming transit package 10.
It is readily understood by those skilled in the art that the number of straps and thus corresponding notches 24 may be increased depending on the weight of the containers and contents to be packaged. For instance, larger beverage cans will require at least two straps to maintain structural integrity of the packaging during transit.
A second embodiment of the transit packaging of the present invention is illustrated in Figures 4 and 5. Containers 48 are like containers which are used to package foodstuffs, such as condensed soups and canned vegetables. Containers 48 are generally characterized by a two piece construction comprising a flat top 50 and cup shaped bottom 52.
The bottom 52 has generally straight sides with an outwardly protruding collar 54 part way down the sides.
In use, the containers 48 are placed on blank 12 such that the bottoms 52 overlay apertures 28. The side panels 16, 18 are plowed upwardly, folding at scores 20 and 22. The bottoms 52 will extend through the apertures 28 and tabs 30 will be thrust outwardly from aperture 28 and downwardly from circular score 34 abutting the upper surface of collar 54.
Figure 5 details the abutment of tabs 30 and collar 54. The tabs 30 are bent downwardly from circular score 34. The inner edges of tabs 30 are forced over collar 54 and are resiliently urged against the sides of container 48 thereby abutting the upper surface of collar 54.
Strap 26 is then wrapped about the containers and blank as in the first embodiment to form transit package 10.
The packages 10 of the present invention are loaded onto pallets. The pallet loads can optionally be wrapped in shrink wrap to protect the pallet load from damage, or additional straps may be used to encircle the loaded packages and secure them to the pallet.
The pallet load is shipped to its destination, unloaded and the packages 10 may be stacked on shelves.
Containers 36 or 48 are removed from the package 10 by cutting the strap 26 and pulling the container 36 or 48 from the blank.
Alternatively for containers packaged according to the second embodiment, the package 10 may be placed on a shelf, the strap 26 cut, and the blank 12 removed by -(-upwardly sliding it off the containers 48, thus readily displaying the containers 48 for retail.
The quantity of packaging of the present invention is dramatically reduced from prior art cardboard cartons, but the structural integrity of the package is maintained minimizing the risk of damage in transit.
In Figure 6, a third embodiment of the present invention is illustrated. The transit packaging of this embodiment is similar to that of the embodiment illustrated in Figures 1-3. However, an additional strap is provided which can be used as a carrying handle.
It is apparent to a person skilled in the art that the transit packaging of the present invention could be readily modified without departing from the scope of the invention as claimed.
It is readily understood by those skilled in the art that the number of straps and thus corresponding notches 24 may be increased depending on the weight of the containers and contents to be packaged. For instance, larger beverage cans will require at least two straps to maintain structural integrity of the packaging during transit.
A second embodiment of the transit packaging of the present invention is illustrated in Figures 4 and 5. Containers 48 are like containers which are used to package foodstuffs, such as condensed soups and canned vegetables. Containers 48 are generally characterized by a two piece construction comprising a flat top 50 and cup shaped bottom 52.
The bottom 52 has generally straight sides with an outwardly protruding collar 54 part way down the sides.
In use, the containers 48 are placed on blank 12 such that the bottoms 52 overlay apertures 28. The side panels 16, 18 are plowed upwardly, folding at scores 20 and 22. The bottoms 52 will extend through the apertures 28 and tabs 30 will be thrust outwardly from aperture 28 and downwardly from circular score 34 abutting the upper surface of collar 54.
Figure 5 details the abutment of tabs 30 and collar 54. The tabs 30 are bent downwardly from circular score 34. The inner edges of tabs 30 are forced over collar 54 and are resiliently urged against the sides of container 48 thereby abutting the upper surface of collar 54.
Strap 26 is then wrapped about the containers and blank as in the first embodiment to form transit package 10.
The packages 10 of the present invention are loaded onto pallets. The pallet loads can optionally be wrapped in shrink wrap to protect the pallet load from damage, or additional straps may be used to encircle the loaded packages and secure them to the pallet.
The pallet load is shipped to its destination, unloaded and the packages 10 may be stacked on shelves.
Containers 36 or 48 are removed from the package 10 by cutting the strap 26 and pulling the container 36 or 48 from the blank.
Alternatively for containers packaged according to the second embodiment, the package 10 may be placed on a shelf, the strap 26 cut, and the blank 12 removed by -(-upwardly sliding it off the containers 48, thus readily displaying the containers 48 for retail.
The quantity of packaging of the present invention is dramatically reduced from prior art cardboard cartons, but the structural integrity of the package is maintained minimizing the risk of damage in transit.
In Figure 6, a third embodiment of the present invention is illustrated. The transit packaging of this embodiment is similar to that of the embodiment illustrated in Figures 1-3. However, an additional strap is provided which can be used as a carrying handle.
It is apparent to a person skilled in the art that the transit packaging of the present invention could be readily modified without departing from the scope of the invention as claimed.
