Abstract

A container and method are provided for storing fat containing liquid products. The container includes a body defining a storage chamber for receiving the product, and a container closure. A first material portion forms at least most of the surface area overlying the storage chamber that can contact any product therein. Neither the body nor the first material portion leach more than a predetermined amount of leachables into the product or undesirably alter a taste profile thereof. A needle penetrable and thermally resealable second material portion either (i) overlies the first material portion and cannot contact any product within the storage chamber, or (ii) forms a substantially lesser surface area overlying the storage chamber that can contact any product therein in comparison to the first material portion. A sealing portion is engageable with the body to form a substantially dry hermetic seal between the container closure and body.
