AI Technical Summary

Benefits of technology

"The present invention provides a packaging system for flexible walled containers that can be securely stacked and transported using wooden pallets. The containers have integrating collars and load transfer means to promote stable load carrying capability. The containers may have upwardly tapering walls and screw cap closures, and the collars have flexible edge portions to engage the caps. The load transfer means may be in the form of board separators or partition means. The system also includes a top sheet with die-cut apertures for penetration and capture of the caps, and laterally and longitudinally extending cut lines or slots for support. The trays may have slightly tapered walls and the top sheet may fit into the base of the tray for easy packaging and reuse. The Z-spacers pack flat with the trays and top sheets."

Problems solved by technology

Owing to the thin-ness of their soft, flexible walls these containers are subject, when loaded externally, to deformation with consequent stress cracking, so that they presently are transported in a substantially loose-packed condition within substantially rigid, fully enclosed cardboard cartons.
The production, use and re-cycling of the vast quantities of material involved requires the ongoing destruction of forests and requires vast quantities of fuel (for transportation), water and power for initial production, and for recycling, when that is practiced.
In Asia CC is recycled so many times as to be significantly weaker and less water-resistant than US recycled fibre, so as to be unacceptable for further recycling.

embodiment 25

[0049] Referring to FIG. 7, in this package embodiment 25, a spacer such as 16 may be supplemented or replaced by a spacer / platform 26 shown in overlaid (but non-applied) relation with the base 14 and the containers 12. The spacer / platform 26 has a die-cut sheet portion 28 with score-cut holes 30 that are sized to receive and engage beneath the lower edges of the caps 24, so as to locate the top portions of the containers 12, when the spacer / platform 26 is pushed down over the underlying caps 24.

[0050] The spacer platform 26 has an upstanding peripheral rim 32 that projects upwardly to be flush with the tops of the container caps 24, so as to provide a supporting base for a superposed like package 10 or 25, which would overly the rim 32.

[0051] It will be understood that for the package embodiment 25 the spacer 16 would be made shorter, so as to be flush with the bottom surface of the sheet portion 28 when sheet 28 has been pushed down to engage beneath the caps 24.

[0052] The load ...

embodiment 101

[0056] It will be understood that different arrangements and smaller numbers of dividers may be used, in accordance with the need for separation of containers, and the desired load bearing capacity of the combined contents and package to meet pallet load requirements. Referring to FIGS. 10 and 11, the embodiment 101 has a bottom tray 102 with eight containers 104, only one of which is fully represented. A top sheet 106 has eight container caps 108 projecting above, and engaged by respective die-cut cap apertures of the sheet 106.

Aperture tabs 110 are engaged beneath the lower edges of the caps 108, to secure the top sheet 106.

[0057] Ten upstanding tab portions 112 project from die-cut tab apertures of the top sheet 106. The upper edges of the tab portions 112 are coplanar with the tops of the container caps 108, to provide support to the tray 102 of an overlying like package.

[0058] The dividers 114 from which the tab portions 112 extend are supported by the tray 102 of the packag...

Abstract

A packaging system for soft-walled plastic containers of tapered or other non-cylindrical shapes has a supporting base to which the containers are secured, with a superposed positioning means engaging the upper portions of the containers; and load transfer spacer sheets extending upwardly in substantially coplanar relation with the tops of the containers, to support a superposed similar package, for palletizing. The package may be strapped, horizontally or vertically and used in plasti-wrapped multi-tier pallet loads. The supporting base may be a tray, which can be of the nesting variety. Formed or die-cut top sheets can be used in combination with the load-transfer spacer sheets

No. 11 / 594,187 filed Nov. 8, 2006.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable REFERENCE TO MICROFICHE APPENDIX [0003] Not Applicable BACKGROUND OF THE INVENTION [0004] 1. This invention is directed to a packaging system for multi-pack stackable structured packaging for shaped containers. [0005] 2. There exists a large family of taper-shaped containers, differing both in shapes and sizes, used for pourable or pumpable fluids, most of which containers are soft, thin-walled plastic bottles. Owing to the thin-ness of their soft, flexible walls these containers are subject, when loaded externally, to deformation with consequent stress cracking, so that they presently are transported in a substantially loose-packed condition within substantially rigid, fully enclosed cardboard cartons. [0006] Cardboard packaging is used extensi...
