Benefits of technology

[0012]The present invention incorporates high-performance, lightweight and recyclable coated corrugated fiberboard material into secondary packaging for military rations wherein a polymeric coated wax alternative medium (WAM) corrugated structure is utilized in lieu of the previous SF-grade fiberboard design. This new generation of fiberboard containers offers numerous benefits over current materials and is environmentally sustainable, utilizing repulpable coatings, and its effective design and enhanced end-of-life disposal capabilities reduce negative environmental impacts. Logistically, the packaging is lighter yet capable of performing in adverse environments and will further reduce the environmental footprint of military rations. Packaging waste is reduced, recyclability is enhanced, and disposal options are increased. In addition, this fiberboard design offers comparable protection during transport, storage and operational use.

Problems solved by technology

In this regard, the aforementioned SF-grade solid fiberboard material currently used in the Meal(s), Ready-To-Eat (MRE™)) ration system is costly to produce and is more expensive than common commercial grades of fiberboard.
This fiberboard material utilizes cellulose and harmful chemicals, thereby depleting natural resources in the environment and creating harmful waste.
The additives enhance the durability of the packaging and adequately protect its contents but limit recyclability.
Moreover, the current MRE™ container design must incorporate multiple manufacturing processes adding to the overall cost.

first embodiment

[0035]The containers are preferably constructed from corrugated fiberboard consisting of 55 pound or 69 pound linerboard facings with a 30 pound corrugating medium material forming a balanced single wall C-flute structure. A water-resistant coating is applied to the linerboard facing material, for example, coatings manufactured under the Spectra-Guard™ name by the Spectra-Kote™ Corporation, in particular its sg48m™ coating. Additionally, WAM is applied to the 30 pound fiberboard forming the C-flute structure of the preferred fiberboard material in order to improve its water resistance. In the first embodiment disclosed infra., an additional corrugated insert having a B-flute structure forms the interior liner.

[0036]A first preferred embodiment is depicted in FIGS. 1, 2, 4-5, and 7 forming a regular slotted container (RSC) specifically sized to accommodate twelve assembled MRE™ rations. The two-piece container 100 of the present invention is assembled from the aforementioned corrugat...

second embodiment

[0040]In a second embodiment depicted in FIGS. 3, 6, and 8, a one-piece container 110 is depicted wherein a slotted container is formed with an integral divider sized to accommodate MRE™ rations. FIG. 3 shows the one-piece container 110 and divider of the present invention fully assembled with its divider in place.

[0041]As shown in FIG. 6, the one-piece container 110 of this embodiment is formed from the one-piece container die cutout 111 as shown. Thickened lines indicate score lines or creases created, for example, by embossing pressure or by a plurality of periodic incisions along the desired crease. The one-piece container die cutout 111 is generally approximately 69 inches in length and approximately 20 inches in width. Elements of the cutout 111 include a one-piece cutout first long sidewall 40 that is generally rectangular in shape and measures approximately 17 3 / 16 inches by approximately 9¼ inches. Adjacent each short dimension or end of this first sidewall 40 are identical...

Abstract

A packaging container having sustainable repulpable/recyclable capability specifically sized to maintain the integrity of the Meal, Ready-to-Eat (MRE™) rations used by the U.S. Army and military services. A coated corrugated fiberboard using a C-flute configuration is utilized in a novel packaging design that incorporates a liner or a vertical container divider.
