Description
- 1. Field of the Invention
- This invention relates generally to the field of plastic containers, and more particularly to plastic containers that require reinforcement against deflection as a result of internal volumetric changes or the weight of the contents of the container.
- 2. Description of the Related Technology
- Plastic containers such as those that are manufactured using the extrusion blow molding process need to possess the requisite strength to limit sidewall and bottom deflection to stay within predetermined tolerances in response to forces that are applied during the filling process and during handling within the supply chain and by the consumer. Hot fill type plastic containers typically include vacuum panel areas having vacuum panels specifically designed to accommodate deflection as a result of the volumetric expansion and contraction that occurs during the filling process. However, it is desirable to minimize deflection in sidewall and bottom portion areas of a hot fill container other than in the vacuum panels in order to preserve the structural integrity of the container.
- The bottom portion of a plastic container also needs to process sufficient strength to resist deformation as a result of pressurization changes within the container and from the forces that are applied by the weight of the container contents. In hot fill type containers, it is also important for the bottom portion to have sufficient rigidity so that vacuum uptake is directed mainly to the vacuum panels that are designed for such purposes.
- In certain types of plastic containers, such as those that are manufactured using the stretch reheat blow molding process, a certain amount of reinforcement is inherently provided by the concave shape of the bottom portion. Concavity can also be designed into the bottom portion of an extrusion blow molded plastic container, but this sacrifices space efficiency and increases material costs. The extrusion blow molding process permits the fabrication of the container that has a substantially flat bottom. Extrusion blow molded containers that have a substantially rectangular profile when viewed in transverse cross-section have been manufactured with corrugated substantially flat bottoms for use in limiting the deflection of the bottom of the container as a result of the weight of solid materials within the container. However, to the inventor's knowledge no such bottoms have been used when the container that is substantially round when viewed in transverse cross-section, or in hot fill applications.
- A need exists to provide a plastic container that effectively directs vacuum uptake to the intended portions of the container, and that limits deflection of the bottom portion as a result of pressurization changes within the container and the weight of the container contents.
- Accordingly, it is an object of the invention to provide a plastic container that effectively directs vacuum uptake to the intended portions of the container, and that limits deflection of the bottom portion as a result of pressurization changes within the container and the weight of the container contents.
- In order to achieve the above and other objects of the invention, a hot fill type plastic container according to a first aspect of the invention includes a finish portion defining an opening, a bottom portion and a main body portion having a vacuum panel area with at least one vacuum panel defined therein. The vacuum panel is constructed and arranged to deflect in order to accommodate volumetric expansion and contraction during the hot fill process. The main body portion further includes a circumferentially extending reinforcement groove having reinforcement structure provided therein. The circumferentially extending reinforcement groove is positioned substantially adjacent to the vacuum panel area, whereby dimensional distortion of at least part of the main body portion that is adjacent to the vacuum panel area is minimized during hot fill process.
- A hot fill type plastic container according to a second aspect of the invention includes a finish portion defining an opening, a bottom portion that is substantially round when viewed in bottom plan and a main body portion having a vacuum panel area with at least one vacuum panel defined therein. The vacuum panel is constructed and arranged to deflect in order to accommodate volumetric expansion and contraction during the hot fill process. The bottom portion is constructed and arranged to include a substantially flat portion having a plurality of alternating parallel ribs and grooves defined therein. As a result, dimensional distortion of the bottom portion is minimized during the hot fill process and deflection as a result of vacuum uptake is directed toward the vacuum panel area.
- A polypropylene container according to a third aspect of the invention includes a finish portion defining an opening, a main body portion having a vacuum panel area defined therein and a bottom portion that is fabricated from polypropylene and that is substantially round when viewed in bottom plan. The bottom portion is constructed and arranged to include a substantially flat portion having a plurality of alternating parallel ribs and grooves defined therein. As a result, dimensional distortion of the bottom portion is minimized.
- These and various other advantages and features of novelty that characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying descriptive matter, in which there is illustrated and described a preferred embodiment of the invention.

reinforcement groove 34 materially improves both the top load and pressure resistance performance of the container in comparison to a similar container that does not include such areinforcement groove 34.FIG. 14 is a finite element analysis comparison depicting the relative deflections under a top load force between a container, shown on the left, which does not include areinforcement groove 34 and the container that is constructed according to the preferred embodiment, which is shown on the right. The darker coloration of the container that is shown on the right is representative of a lessened amount of deflection relative to the container on the left. -
FIG. 15 is a graphical depiction of the relative top load performance of the containers shown on the left and right, respectively, inFIG. 14 . The horizontal axis inFIG. 15 represents displacement, while the vertical axis represents a top load force that is applied to the container. The container that is shown on the left inFIG. 14 , which does not include a profiledreinforcement groove 34, as indicated as the “original structure” inFIG. 15 . The container that is shown on the right inFIG. 14 is constructed according to the preferred embodiment of the invention and does include areinforcement groove 34, is indicated as the “final structure” inFIG. 15 . AsFIG. 15 shows, a significant improvement in top load performance is achieved by the inclusion of the profiledreinforcement groove 34. - Referring now to
FIGS. 11 and 13 , it will be seen that thebottom portion 16 is constructed and arranged to include a substantiallyflat portion 52 that has a plurality of alternatingribs 56 andgrooves 58 defined therein. The presence of the alternating ribs andgrooves bottom portion 16 during the hot fill process and direct deflection as a result of vacuum uptake to portions of thecontainer 10 that are designed to accommodate such uptake, namely thevacuum panel area 20. -
