Definitions

• the invention relates to a packaging for hydrocarbon fluids. More particularly, the invention relates to a container having a flexible pouch within a more rigid exterior container.
• Automobile service centers and other entities having a need for large volumes of hydrocarbon fluids such as motor oil, transmission fluid or brake fluid, generally stock these materials in 55 gallon drums or 5 or 6 gallon pails or 16 gallon kegs.
• hydrocarbon fluids such as motor oil, transmission fluid or brake fluid
• Each of these containers present significant disadvantages.
• the 55 gallon drums are extremely heavy and difficult to handle.
• the circular shape of the drums gives rise to vacant space during transportation thereby decreasing the efficiency and raising the costs of transporting and delivering these fluids.
• individual one quart plastic containers such as those typically purchased by individual consumers, may be used by larger volume users.
• hydrocarbon fluids container for large volume users which is economical, uses less storage space, is lighter weight and results in less waste packaging and oil.
• "Bag-in-a-box" containers substantially meet these needs.
• Most such containers utilize polymer pouches, such as polyethylene, as inner pouches which contain the liquid.
• Polymers which may be used as pouches for hydrocarbon fluids must have both good mechanical properties and good resistance towards hydrocarbon fluids. With the latter property there appears to be a correlation between the nature of the hydrocarbon fluid and the polymer composition. While thin polyethylene films are extremely economical, flexible and transparent and have low moisture vapor permeability, such films are permeable to oil. Increasing the thickness of the polyethylene material such that the material becomes practicably impermeable to hydrocarbons fluid is well known. However, to achieve sufficient thickness, flexibility is sacrificed and the resulting product is a rigid polyethylene container.
• One method to decrease the permeability of thin polyethylene films to hydrocarbon fluids involves laminating a poly-vinylidene chloride onto the polyethylene film.
• laminates with sufficient thickness to block permeation of hydrocarbon fluids are brittle and easily ruptured.
• Fluorinated polyethylene films are also resistant to hydrocarbon fluids but large scale production of such material is impractical and expensive.
• the hydrocarbon fluids packaging of the invention meets these and other needs.
• the invention provides a "bag-in-a-box" type packaging for hydrocarbon fluids having a flexible, collapsible, sealable interior bag or pouch which prevents leakage and sweating.
• the hydrocarbon fluids packaging further includes a rigid container formed in a shape, such as a solid rectangle.
