Definitions

  • the present invention relates to pressurized containers or vessels made from reinforced thermoplastics and methods for making pressurized containers or vessels from reinforced thermoplastics.
  • plastics for pressurized containers primarily for containing beverages, but increasingly for other utilities such as containers to dispense either gaseous or liquid carbon dioxide for use in pneumatic power devices such as garden pressure sprayers, power tools, etc. wherein the high pressure carbon dioxide provides mechanical power.
  • plastic containers in applications such as fire extinguishers, cylinders containing medical gases for distribution in laboratories and larger (e.g. 5 to 50 liters capacity), and cylinders such as those used in the distribution of oxygen, nitrogen, carbon dioxide and the like to industrial users.
  • U.S. Patent No. 3,712,497 discloses bottles formed of thin walled, flexible synthetic plastics, in separate parts which are later friction welded together forming the bottles, capable of withstanding internal pressures of up to 75 psi.
  • U.S. Patent No. 4,591,066 discloses a unitary molded plastic body for containing pressurized liquid beverage made out of polystyrene, PET, or polypropylene.
  • these containers are quite permeable to carbon dioxide.
  • beer stored in the plastic containers of the prior art will have lost so much of its carbon dioxide content after a few days that the remaining beer will no longer be palatable and flat-tasting.
  • EP 0 578 711B1 discloses an improved container for beer and other beverages in the form of a layered construction of at least two plastic materials, with the plastic materials being arranged in adjacent layers fastened together, or being laminated together.
  • the improved container herein can withstand pressure of up to approximately 420kPA or about 65 psi.
  • the first plastic material is a polyethylene terepthalate
  • the second plastic material is nylon.
  • the invention relates a pressurized container made of reinforced polyesters having sufficient creep resistance, impact strength, CO 2 and O 2 barrier resistance, wherein upon being filled with a liquid having a dissolved carbon dioxide content of in the range of 0.4 - 0.6 wt % at an internal pressure of at least 1 bar, said pressurized container maintains a dissolved carbon dioxide content of at least about 0.25 wt % after 6 months at a storage temperature of about 30 to 35 °C, and an O 2 -permeation of less than 1.0 ppm.
  • the invention also relates to the use of long-glass fiber reinforced polyesters in pressurized containers for excellent creep resistance, impact strength, water and CO 2 /O 2 barrier properties.
  • reinforced plastic materials i.e., polyesters reinforced with various materials, e.g., long-glass fibers, provide a combination of excellent barrier and physical properties such as low permeability to gases, high strength, and low creep at elevated temperatures, thus excellent for packaging applications such as pressurized containers for beverages and foodstuff.
  • polyester resins utilized in this invention include, in general, linear saturated condensation products of diols and dicarboxylic acids, or reactive derivatives thereof. Polyesters are well known as film and fiber formers, and they are manufactured by methods known in the art including those disclosed in U.S. Pat. Nos. 2,465,319 and 3,047,539.
  • the polyesters comprise condensation products of aromatic dicarboxylic acids and aliphatic diols.
  • the polyesters are poly(1,4-dimethylol cyclohexane dicarboxylates, e.g., terephthalates).
