Definitions

  • the invention relates to a plastic container and more particularly, to an improved plastic container structure of the type suitable for containing carbonated beverages.
  • the bottling of carbonated beverages in plastic containers presents a number of problems, many of which arise in connection with the structure of the central portion of the container, particularly when the overall plastic content is decreased in weight.
  • Mere plastic duplication of the traditional glass bottle design configuration is deemed unsatisfactory for a myriad of reasons, one of which is the tendency of the resultant container to feel somewhat flimsy in the hand of the ultimate user.
  • mere duplications in plastic sometimes are unsatisfactory due to the fact that plastic materials have a tendency to creep or become otherwise distorted when the containers are filled with carbonated beverages or other fluids under pressure.
  • Such distortion may alter the shape and dimensions of the container configuration which tends to adversely affect the application of indicia containing outer wraps and result in a distortion of the wrap and integral indicia.
  • the above noted problems can threaten customer acceptance or satisfaction of the product within the container.
  • a plastic container when filled with a carbonated beverage and capped, must be able to withstand the impact of falling from at least a moderate height and must be dimensional stable in respect of the outer shape and dimensions to enable the container to be of the same capacity as glass containers so that they may be handled or processed by existing equipment and assist in customers' identification of the particular product contained therein.
  • Aesthetic appearance is typically a given requirement .
  • the plastic container when the plastic container becomes distorted by the internal pressure, it may become unstable on a horizontal surface. Such instability may result in a probability of an adverse customer reaction toward the container contents.
  • plastic container structures illustrating and describing improved bottom structures for plastic containers of the type suitable for containing carbonated or effervescent beverages .
  • an improved plastic container of the type suitable for carbonated beverages for example, contains a central section having a portion thereof which tends to change or vary at least in the outermost configuration as a result of internal pressurization, typically due to the presence of a carbonated beverage. More specifically, the portion is caused to assume or approach a circular cylindrical shape upon pressurization and thence will return to its original shape upon depressurization due to the memory of the plastic material forming the container wall.

  • Figure 19 is a fragmentary elevational view of another embodiment of the invention.
  • Figure 20 is a fragmentary sectional view of the embodiment illustrated in Figure 19 taken along line 20- 20.
  • a plastic container constructed generally in accordance with the teachings of the invention and is preferably formed of a thermoplastic material having gas barrier properties to such a degree that the container will be suitable for containing a carbonated beverage at least throughout the expected shelf-life which typically is the period from the bottling of the beverage to consumption.
  • a number of materials having the above properties have been developed.
  • a preferred material for forming the container of the invention is a polyethylene terephthalate (PET) product by Shell Oil Company under No. 8006 and having an intrinsic viscosity of .80.
  • the container is typically blow-molded from an extruded or injection molded preform or parison and has preferably been so worked that the material is biaxially oriented.
  • the container typically includes an upper section 10, a base section 20, and a central section 30.
  • the upper section 10 is provided with neck portion 12 having any desired neck finish such as the threaded finish shown.
  • the threaded neck portion 12 is adapted to receive an internally threaded closure member 14 as illustrated in Figure 3.
  • the upper section 10 is formed to contain a plurality of parallel flutes 16 separated by valleys or grooves 18.
  • the base section 20 has an outer surface 22 provided with generally radially arranged contoured foot portions 24.
  • the foot portions 24 extend outwardly and are illustrated as preferably being five (5) in number.
  • the number of foot portions 24 is not deemed to be critical and may be as low as three, the minimum number required to provide stable support on a planar surface, and the maximum number is limited only by the overall dimensions and wall thickness of the base section 20.
  • the base section 20 is formed to contain a plurality of parallel flutes 26 separated by valleys or grooves 28.
  • the central section 30 is formed of a plurality of juxtaposed flat panels 32 and interconnects the upper section 10 and the base section 20. It will be noted that at the juncture of the lower end of the upper section 12 and the upper end of the central section 30, there is an inwardly formed step caused by the reduced diameter of the central section 30. A similar inwardly formed step is formed at the juncture of the upper end of the base section 20 and the lower end of the central section 30.
  • An annular outwardly extending portion 38 is formed in the base section 20 intermediate the lower termination of the flutes 26 and associated valleys 28, and the upper termination of the foot portions 24.
  • the flutes 16, 26 and the associated valleys 18, 28 respectively, are deemed to be functional as well as aesthetic. More specifically, the valleys 18, 28 provide necessary conduits of moisture formed from condensate leaving the flutes 16, 26 somewhat free from moisture when grasped by the hand of a person handling the container.
  • the flutes 16, 26, the valleys 18, 28, and the flat panels 32 cooperate to lend rigidity, and stiffness to the container, particularly in the unpressurized condition. Thereby, the hand of the ultimate user is left with a pleasing and comfortable reaction towards the container and its contents.
  • Figure 3 and 4 illustrate the container of Figures 1 and 2 after it has been filled with a pressurized fluid such as, for example, a carbonated beverage generally indicated by the reference numeral 40.
  • the pressurized fluid 40 is typically filled to a fill line 41.
  • the relative smoothness of the center section 30 in the pressurized condition is of particular advantage from an identification standpoint.
  • the trademark and contents of the internal beverage may now be applied to a separate plastic film overlay or overwrap. Due to the substantially uninterrupted exterior of the central section 30 in the pressurized state of the container, the associated film containing the printed indicia, is likewise unfettered with wrinkles or other irregularities which otherwise would adversely affect the appearance of the trademark and other recognition and advertising indicia thereon. The resultant appearance is pleasing to the ultimate consumer achieving one of the important sales objectives of the bottler of the carbonated beverage.

  • the upper section 10' is provided with neck portion 12' having any desired neck finish such as the threaded finish shown.
