Abstract

Sealable liquid-tight containers and methods for economically manufacturing such containers for storing and dispensing substances and any other purposes for which conventional sealable liquid-tight containers are utilized. The containers are readily and economically formed from mixtures of hydraulically settable binders such as hydraulic cement, gypsum and clay with water. Appropriate additives can also be added to the mixture which impart desired characteristics and properties to both the mixture and the hardened containers. The mixtures can be utilized to form containers by various methods. One method involves forming the containers without substantial mixing of the mixture, compacting the mixture and hydrating the mixture. Other methods involve molding the mixture, extruding the mixture and forming sheets from the mixture to be converted into containers. The components may also be dried, coated, lined, laminated and/or receive printing.
