Definitions

  • the present invention relates to light weight, extrusion blow molded plastic containers particularly containers for use in the milk and related beverage industries.
  • One gallon and other size plastic containers are the containers of choice for milk and other liquids.
  • One significant factor in the cost of such containers is the amount of resin required to produce the container or jug. Cost is most often reduced by manufacturers by attempting to reduce the amount of resin in each container. Because of the large volume of containers produced, even a small reduction in resin content results in significant savings. Unfortunately, when the amount of resin forming the container is reduced beyond a certain weight, it is difficult to structurally provide a container which will remain stable and retain an attractive appearance once filled. Typically, containers of inadequate strength will evidence a bulge or sag in its sidewalls or easy denting in its corners.
  • Another object of the present invention is to provide a container which, while using less resin, is formed so as to have sidewalls which do not excessively bulge when filled.
  • a plastic container having a bottom portion, sidewall portions, and a top wall portion.
  • the sidewall portions include four face panels and four intermediate panels. The latter panels are narrower in width than the face panels and are connected on each vertical side to a face panel. This connection generally improves the container with a cross section therethrough in the shape of an octagon.
  • Each sidewall portion, between the bottom portion and the top wall portion, is also slightly indented. The octagon body shape and the indention of the sidewall portions disperses internal pressures to reduce bulging and also provide a protected area for the container's label.
  • Additional support for the sidewalls is provided by a plurality of concave horizontal ribs circumscribing at least part way around the sidewall portions.
  • the horizontal ribs may extend in a continuous manner from one face panel through an intermediate panel and the adjacent face panel. Alternatively, the horizontal ribs may be discretely formed in each panel or only some of the panels.
  • the face panels may be provided with indentions of preferably a circular configuration.
  • the size and depth of the indentations may be varied to control fill level of a given volume of contents in the container in addition to further stabilizing the sidewalls.
  • the top wall portion of the container extends from the sidewall portions and merges with a neck that defines the mouth of the container.
  • the container is provided with a handle that is also constructed to combat weakness during light weighting of the container.
  • the bottom portion is provided a concave groove extending thereacross and the groove incorporates a rib perpendicular thereto.
  • FIG. 1 is a perspective view of the plastic container of the present invention
  • FIG. 2 is a side elevational view of the container
  • FIG. 3 is a front elevation view of the container
  • FIG. 4 is a rear elevational view of the container
  • FIG. 5 is a top plan view of the container; and FIG. 6 is a bottom plan view of the container.
  • FIG. 1 a plastic container 10 according to the principles of the present invention and formed by conventional extrusion blow molding techniques is illustrated in FIG. 1.
  • the containers 10 themselves may be made from any suitable plastic material, such as polyethylene resin.
  • Conventional milk containers normally use 58-65 grams of blow molding grade, high density polyethylene resin to make a one gallon container.
  • a stable one gallon container may be made using less than 58 grams of resin, preferably using only 52 grams of resin, more preferably only 50 grams of resin.
  • the container 10 has a bottom portion 11 , sidewall portions (collectively designated as 12), and a top wall portion 14.
  • the sidewall portions 12 include four face panels 16, 18, 20, 22, and four narrower intermediate panels 24, 26, 28, 30 all unitarily formed with one another.
  • connection of the four face panels and the four intermediate panels forms an eight-sided shape, namely an octagon.
  • the octagonal body shape has been found to allow for more even resin distribution during the blow molding process thereby providing for better stability during light weighting.
  • each sidewall portion 12 is recessed slightly inward.
  • the recessed area 32 is defined on its top and bottom by label bumpers 33 and is sufficiently wide to accommodate a label positioned around the circumference of the container. The recessing of this area is of a sufficient amount to provide increased stability to the container.
  • the overall octagon body shape combined with the recessed sidewall portions 12 disperses internal pressures and cooperates to reduce bulge in the sidewall portions 12 when filled.
  • three concave ribs 40, 42, 44 each of equal depth, circumscribe at least a portion of the container 10 and are positioned in the face panels 16, 18, 20, 22.
  • the ribs serve to reinforce and provide strength to the container 10. It should be understood that while three ribs are preferred, a lesser or greater number of ribs could be employed. Further, the ribs may completely circumscribe the container or be discretely provided in the intermediate panels 24, 26, 28, 30. In an alternative embodiment, seen in the split embodiment of FIG. 3 (as well as in
  • one or more of the face panels, face panel 16 in the FIGS. include a circular indentation 46.
  • the size and dept of the indentations 46 may be varied further and are used to control the fill level of the container 10 as well as to further stabilize the container sidewall 12.
  • the container 10 is formed using conventional extrusion blow molding techniques. In forming a container according to the present invention, it is preferable that the wall thickness be maintained substantially the same throughout the container 10. It will be understood, however, that there will inevitably be some small variations in wall thickness.
  • the top wall portion 14 extends from the sidewall portions 12 and merges to a neck
  • the container is also provided with a handle 50.
  • the handle area itself is provided with a compression rib 52 extending in the top portion from the upper end of the handle 50 to the lower end of the handle 50.
  • This rib 52 provides firmness during lifting and reduce the chance of splitting the container 10.
  • the bottom portion 11 is provided with a concave groove 13 extending thereacross.
  • the cross-bottom groove 13 is intersected by a perpendicular rib 15 and a slight recessed groove 19 that runs all the way axially with the rib 15 across the bottom portion 11.
  • the groove 13 and the rib 15 serve to eliminate the traditional push-up style base and allows for further light weighting and while providing increased stability to the bottom portion.
  • the container design of the present invention is the ability to use a sleeve label which encircles the entire container and which is placed in a protected area. This provides for greater labeling options.
  • the use of less high density polyethylene provides cost savings and the use of a reinforced eight-sided structure provides for increased stability.

Abstract

L'invention se rapporte à un contenant (10) en plastique, en forme d'octogone ou à huit faces, comportant une partie inférieure (11), des parties latérales (12) et une partie de paroi supérieure (14). Les parties latérales comprennent quatre panneaux (16, 18, 20, 22) avant et quatre panneaux de raccordement (24, 26, 28, 30) quelque peu plus étroits, tous assemblés respectivement au niveau de leurs côtés latéraux à l'un des côtés des panneaux avant. Une zone (32) de chaque partie de paroi latérale, située entre la partie inférieure et la partie de paroi supérieure, est renfoncée sur une faible profondeur et une pluralité de nervures horizontales concaves (40, 42, 44) sont disposées au moins sur une partie du pourtour de la portion de paroi latérale. La partie de paroi supérieure fait saillie à partir des parties de paroi latérale et s'assemble au col (17) qui définit l'orifice de sortie du contenant.
