Container
A rigid beverage container for cold fill applications is disclosed. The container is made from a polymer with a moisture vapour transmission rate of greater than 100 g/m2.day at a 25 um wall thickness. The container includes one or more than one panel that is responsive to vacuum conditions generated in the container and can accommodate in a controlled way any vacuum contraction caused by the loss of liquid from the container when the container has been cold filled with a liquid, such as a beverage, and closed.

- 1. A rigid container for liquid products for cold fill applications made from a polymer with a moisture vapour transmission rate (“MVTR”) of greater than 100 g/m2.day at a 25 um wall thickness that includes one or more than one panel that is responsive to vacuum conditions generated in the container and can accommodate in a controlled way any vacuum contraction caused by the loss of liquid from the container when the container has been cold filled with a liquid product, such as a beverage, and closed.
- 4. The container defined in any one of the preceding claims wherein the polymer has a MVTR of greater than 200 g/m2.day at a 25 um wall thickness.
- 5. The container defined in any one of the preceding claims wherein the polymer is biodegradable in landfill or compost conditions.
- 6. The container defined in any one of the preceding claims wherein the polymer is a polylactic acid based polymer.
- 7. The container defined in any one of the preceding claims wherein the polymer is a co-polymer of the polylactic acid based polymer and another polymer or polymers.
- 9. The container defined in any one of the preceding claims wherein the vacuum panel is in a body of the container.
- 10. The container defined in any one of the preceding claims when cold filled with a liquid product, such as a beverage, and closed.
