Definitions

• the present embodiments relate generally to liquid containers, and more particularly to bottles with improved structural stability desirably configured to be formed from a fully recyclable material, such as an organically-based biopolymer.
• the containers may be used for numerous types of liquids, including waters, juices and other types of beverages, as well as for non-beverage liquids.
• Recyclable materials are well known in the art, and are commonly used for both products (newspapers, for example) and for packaging for products (bottles for beverages, for example) (collectively, "products"). Paper, glass, plastics, cardboard and the like are readily recycled through refuse collection programs in homes and business.
• Such programs involve the use of designated containers for recyclable products. When a recyclable product is ready to be discarded, it is placed in an appropriately- labeled container (paper, glass, plastic, etc.) and it is collected by a waste hauler along with other, non-recyclable waste.
• PET polyethylene terephthalate
• PET bottles are considered “recyclable,” it is estimated that approximately 80% of PET bottles end of up in landfills and never get recycled. Additionally, a number of petroleum-based plastics, such as polystyrene (#6), are not recyclable at all.
• PET bottles formed from a non-renewable material such as Puroleum
• the production and disposal of petroleum-based plastics can have negative environmental and societal effects, such as increased dependence on oil, increased creation of greenhouse gases, increased pollution, increased usage of landfills and increased public litter.
• bottles formed of organically-based biopolymer materials may have a relatively short "shelf life,” on the order of six months or less, before the structural integrity of the bottle begins to fail and the bottle undesirably undergoes deformation.
• Such deformation often includes contraction or collapse of the bottle walls known as "paneling." Paneling of a bottle creates an unsightly appearance and can cause label distortion, stress cracking and spillage or leakage of the bottle contents.
• bottles formed of organically-based biopolymer materials are to be accepted and used on a widespread basis, and if the environment and societal benefits of fully-recyclable bottles formed from organically-based biopolymer materials are to be recognized in a meaningful way, it is crucial that such bottles be configured to have improved structural stability to counteract the inherent characteristics of organically-based biopolymer materials.

However, greater or fewer upper panels 9 (109) may be used without departing from the spirit of the present embodiments.
