Definitions

  • This invention relates to containers and more particularly to containers suitable for hot filling with perishable foods or beverages.
  • Perishable foods such as juices and soup
  • a perishable food or beverage is introduced into a plastic container at approximately 185 °F and a cap is applied to seal the container.
  • a negative pressure that is, below atmospheric pressure
  • the container may also shrink upon being subjected to hot-filling temperatures, but the product contents generally shrink by a greater volumetric amount upon cooling than the decrease in container volume.
  • containers In order to withstand the temperatures common to hot-filling, containers typically are formed of a thermoplastic having a relatively high intrinsic viscosity and typically are heat treated. For example, a container may be formed in a heated blow mold, which is maintained at approximately 250 0 F to 290 °F. A container that is held in a heated blow mold undergoes a decrease in the orientation of the polymer and an increase in its crystallmity, which diminishes the distortion of the container when subjected to hot-fill temperatures.
  • Containers suitable for hot-filling applications typically are designed with vacuum panels formed in the container sidewall that flex in response to a decrease in internal pressure.
  • some plastic containers have several, equidistantly spaced vacuum panels that are configured to enable a circular label to be wrapped around the container. Land areas between the panels provide surfaces around which the label may be applied. Inward flexing of the vacuum panels in response to vacuum pressure prevent severe distortion of the land areas.
  • Other plastic containers are configured to have opposing hand-grips that flex to absorb the internal vacuum. Flexing of the hand- grips in response to internal negative pressure prevents severe distortion of the surfaces to the front and to the rear of the hand-grips, which can receive labels.
  • hot-fill containers are configured to function under internal vacuum conditions, the containers are sometimes subjected to positive internal pressure during the filling process.
  • some filling equipment subjects the container to internal positive pressure for a brief period.
  • Containers having long stiffening ribs or other long stiff structures may, in response to positive internal pressure, locally bulge outwardly in a kink. And the kink might remain even after the container encounters internal vacuum or the kink may disappear but leave a wrinkle in the plastic wall. Even a wrinkle makes the container unappealing and is considered to be commercially detrimental.
  • the specifications for such processes require the containers to withstand internal positive pressures of up to 3 psi. It is possible, however, for a pressure filling line to stop during the filling process, for example under unexpected or alarm conditions, and subject the container being filled to a filling pressure of greater than 3 psi.
  • a container capable of being hot filled with a product, sealed while the product is hot, and allowed to cool, thereby creating an internal vacuum.
  • the container has improved positive pressure resistance during pressure filling and yet has sufficient vacuum absorption capabilities.
  • the container has an enclosed base, a body having a sidewall that extends upwardly from the base, and an upper portion extending upwardly from the body to a finish on which a closure may be applied.
  • the container also includes a pair of opposing vacuum panels disposed between front and rear portions of the sidewall of the body.
  • the container has relatively smooth transitions between its vacuum panels and the front and rear portions of the sidewall and the container does not have vertical reinforcing ribs such that the radial dimension is small for each portion of the front and rear edges of the panel.
  • the vacuum panels have a generally flat field that transitions smoothly into the front and rear portions of the sidewall.
  • the vacuum panels each include a handgrip and a pair of inwardly extending windows formed at least partly in the field generally below the handgrip.
  • the handgrip includes a gripping surface and at least a proximal wall and a distal wall. The gripping surface is adapted to receive a user's fingers on one of the vacuum panel handgrips and a user's thumb on the opposing one of the vacuum panel handgrips.
  • the proximal wall of the handgrip preferably merges smoothly with the rear portion of the sidewall
  • the distal wall forms an oblique long wall angle Al with a vertical line in elevational view and a short wall angle A2 with the field in transverse cross section.
  • the long wall angle Al is preferably between approximately 10 degrees and approximately 25 degrees.
  • the short wall angle A2 is preferably between approximately 85 degrees and approximately 115 degrees.
  • the radial component preferably has a relatively short vertical length in elevational view and is nearly radially oriented in transverse cross section.
  • the container is designed to preferably achieve a failure mode in the form of a bulge in the handgrip distal wall when the container is subjected to a positive internal pressure.
  • the container can withstand and internal positive pressure of between 3.5 and 7.5 psi.
  • a method of hot-filling a bottle According to the method, a bottle that is designed in accordance with the above description of the container is filled with contents at an elevated temperature and at a positive pressure of up to 9.0 psi. Then, the bottle is capped while the contents are still at an elevated temperature and the contents of the capped bottle are allowed to cool, which causes the vacuum panels to deflect inwardly in response to the cooling and shrinking of the contents.
  • Figure 1 is a side elevational view of a bottle illustrating features of the present invention
  • Figure 2 is a front elevational view of the bottle of Figure 1;
  • Figure 3 is a transverse cross sectional view of the bottle of Figure 1 taken through lines III-III in Figure 1 ;

  • a bottle 10 includes an enclosed base 12, an upper portion 14, and a body 16 extending between base 12 and upper portion 14, as best shown in Figures 1, 2, 6, and 7.
  • Bottle 10 is generally suitable for use in a hot-filling process, in which bottle 10 is filled with a product at an elevated temperature, capped, and allowed to cool.
  • bottle 10 is formed by an injection blow molding process, but the present invention is not limited by the method of forming the bottle.

  • Upper portion 14 includes an upper shoulder 28, a waist 30, a dome 32, and a finish 34. Finish 34 includes threads for receiving corresponding threads of a closure 36 (shown Figures 6 and 7).
  • Upper shoulder 28 is located at the boundary between upper portion 14 and body 16.
  • Waist 30 is a portion of reduced diameter located above shoulder 28 and below dome 32. Dome 32 diminishes in diameter as it upwardly extends toward finish 34. Tn the figures, dome 32 is illustrated with structural elements, but neither these structural elements nor any other aspect of upper portion 14 is intended to be limiting unless expressly recited in the claims.
  • Body 16 includes a sidewall 38 and a pair of opposing vacuum panels
  • Front portion 42 generally extends between shoulders 26 and 28 and preferably includes a front portion 42 and a rear portion 44.

  • Preferably, neither front portion 42 nor rear portion 44 have horizontal stiffening ribs.
  • Front portion 42 preferably a surface capable of receiving a label.
  • the label surface of front panel 42 is generally straight in longitudinal cross section, but it is expected and acceptable for the longitudinal cross section of front portion 42 to deflect slightly in response to internal pressures within bottle 10.
  • the desired magnitude of the deflection of front panel 42 is governed by label considerations, as will be understood by persons familiar with labeling technology for hot fill containers.
  • Stiffening ribs 46a and 48b are curved to match the curvatures of panels 42 and 44, respectively, and terminate at ends 48a and 48b, respectively.
  • sidewall 38 extends, rearward and arcuately, past ribs ends 48a of front portion 42; and sidewall 38 extends, frontward and arcuately, past rib ends 48b of rear portion 42; which portions of the sidewall are referred to a sidewall intermediate portions 50a and 50b, respectively.
  • sidewall intermediate portions 50a and 50b do not have vertical stiffening ribs, or (ii) have ribs that have only a small vertical component (such as curved ribs or ribs forming an oblique angle with a vertical line), or (iii) have only horizontal ribs, or (iv) have stiffening structure that is part of a three dimensional window (described more fully below) and that has a small vertical dimension.
  • Each vacuum panel 40 includes a field 56 that is defined by the panel's front edge 58a and its opposing rear edge 58b.
  • Figure 1 and Figure 4 show panel edges 58a and 58b in dashed lines to schematically show the boundaries of the vacuum panel, as the boundary in the physical version of bottle 10 is not pronounced, which is evident in Figure 3.
  • Field 56 is generally planar in its as-molded state, but may also be curved.
  • Each panel 40 also includes a handgrip 60 and a pair of inwardly directed first window 90 and second window 96.
  • Handgrip 60 includes a gripping surface 62 that preferably includes a pair of ribs 64.
