Container with oxygen and moisture barrier and scavenger capability
A storage system for storing a product sensitive to oxygen or moisture includes a container with a bottom, a top edge defining a top opening, and a wall extending between the bottom and the top edge. The bottom, top edge, and wall define an inside volume. The system further includes a sealing member removably attached to the top edge and sealing the top opening, and a scavenger element in fluid communication with the inside volume, where the scavenger element is constructed to absorb moisture, oxygen, or a combination thereof. The wall and the bottom of the container include layers with at least one of an in-mold label, an oxygen barrier, or a moisture barrier. The system may further include a scavenger compartment and a retainer disc for retaining the scavenging element in the scavenger compartment. The container may optionally be flushed with an inert gas and hermetically sealed, and be closed with a lid.
1. A packaged food product comprising:
a container comprising a bottom, a top edge defining a top opening, and a wall extending between the bottom and the top edge and comprising an inside surface and an outside surface, wherein the bottom, top edge, and wall define an inside volume;
a holding element extending radially inwardly from the inside surface of the wall;
a retainer disc between the bottom and the holding element;
a sealing member removably attached to the top edge and sealing the top opening;
a scavenger element positioned between the bottom and the retainer disc, the scavenger element constructed to absorb substantially all moisture and oxygen from the air in the inside volume and selected from the group consisting of elemental iron, iron powder, autoclaved clay, sodium chloride, calcium, ascorbic acid, zeolite, oxazolidine, aluminosilicate, polymer, and mixtures thereof,
wherein the wall and the bottom comprise a plurality of layers including at least one barrier layer such that the barrier layer has an oxygen transmission rate of 10 cm 3 /m 2 /day or less and a water vapor transmission rate of 10 g/m 2 /day or less; and
a dried meat product located in the inside volume.
2. The packaged food product of claim 1 , wherein one layer of the wall and bottom is molded plastic.
3. The packaged food product of claim 1 , wherein the holding element is positioned circumferentially along the inside surface and configured to hold the retainer disc in place thereby forming a scavenger compartment in the container below the retainer disc.
4. The packaged food product of claim 1 further comprising a lid removably coupled with the container and covering at least a majority of the sealing member.
5. The packaged food product of claim 4 , wherein the lid is constructed of molded plastic.
6. The packaged food product of claim 5 , wherein the lid further comprises a barrier layer.
7. The packaged food product of claim 1 , wherein the sealing member is a foil seal.
8. The packaged food product of claim 1 , wherein the container comprises an inert gas housed in the inside volume.
9. The packaged food product of claim 4 , wherein the lid has an oxygen transmission rate of 10 cm 3 /m 2 /day or less.
10. The packaged food product of claim 4 , wherein the lid has a water vapor transmission rate of 10 g/m 2 /day or less.
11. The packaged food product of claim 1 , wherein the barrier layer has an oxygen transmission rate of 1 cm 3 /m 2 /day or less and a water vapor transmission rate of 1 g/m 2 /day or less.
12. The packaged food product of claim 1 , wherein the barrier layer is an in-mold label.
13. The packaged food product of claim 1 , wherein the barrier layer comprises of a coextruded cast or blown film material selected from the group consisting of: polypropylene, orientated polypropylene, ethylene vinyl alcohol, nylon, polyamide, orientated polyamide, polyethylene, polyethylene terephthalate, and combinations thereof.
14. The packaged food product of claim 1 , wherein the container improves the shelf life of the dried meat product by at least 75 days.
15. The packaged food product of claim 1 , wherein the container improves the shelf life of the dried meat product by at least 40 days.
16. The packaged food product of claim 1 , wherein the container improves the shelf life of the dried meat product by at least 120 days.
17. The packaged food product of claim 1 , wherein the container improves the shelf life of the dried meat product by at least 14 days.
18. The packaged food product of claim 1 , wherein the holding element is a continuous lip inwardly extending from the inside surface of the wall.
