A card-based package for sensitive food products, comprises a container portion defining an interior space with a base and a sidewall extending to an upper peripheral edge for receiving a removable seal for hermetically sealing the container portion prior to use. The package further comprises a lid structure, that can open and close to allow selective access to the interior space after removal of the seal. The container portion and the lid structure are both formed of card-based material and at least the container portion has light, oxygen, and water vapour barrier properties sufficient for storage of the product for a period exceeding 24 months.

A method for forming an overwrap container includes the steps of a) providing a base container having a first side seam on a side wall that extends along a longitudinal axis to define an internal volume, and a bottom secured to the side wall; b) providing the side wall of the base container with connecting elements on an outer periphery of the side wall; c) providing an overwrap having a second side seam over the side wall of the base container such that the overwrap is joined in spaced apart relationship by the connecting elements to the side wall of the base container; d) clamping the overwrap to the base container along the second side seam to form a first compressed area; e) clamping the overwrap to the base container in an area 180° removed from the second side seam to form a second compressed area: and f) reforming the second compressed area to define an overwrap container having a substantially uniform spacing and air gap between the base container and the overwrap except in the first compressed area.

An insulating transport/storage container for transporting/storing temperature sensitive materials, with a generally tubular wall element defining a load volume between first and second apertures at either end thereof, the tubular wall element having an axis. First and second closures operate to close first and second apertures and fastening means operable to secure said first and second closures. The tubular wall element comprises a multiple-layer winding of single-sided corrugated sheet, with the layers coupled together whereby to define a high level of thermal resistance.

A coated paperboard container includes an inner paperboard substrate, an outer paperboard substrate, a first aqueous barrier coating located on the inner paperboard substrate, and a second aqueous barrier coating located on the outer paperboard substrate. The inner paperboard substrate and the outer paperboard substrate are coupled with an adhesive. The first aqueous barrier coating and the second aqueous barrier coating include a pigment and a binder and the first aqueous barrier coating is heat sealable.

A container blank including a paperboard shell layer and a core layer. The container blank has a predetermined removable portion the provides for a separable cap portion after the container blank is erected. The container blank can include a lobe for tightly fitting the cap portion to the body portion of the erected container and or provide for a core rim that is located at a rim distance that is a function of position about the longitudinal axis of the container and or include at least one dosing indicia.

A container including a paperboard shell layer and a paperboard core layer. The container has a predetermined removable portion the provides for a separable cap portion. The body portion of the container extends from the shell bottom edge to a lower line of limitation. The body portion includes a lobe beneath the lower line of limitation defining the body. The lobe can be used to tightly fit the cap portion to the body portion after opening the container.
