BRIEF DESCRIPTION OF THE DRAWINGS
(1) The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:

(9) It should be noted that some details of the FIGS. have been simplified and are drawn to facilitate understanding of the present teachings rather than to maintain strict structural accuracy, detail, and scale.
DETAILED DESCRIPTION
(10) The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
(11) As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range. In addition, all references cited herein are hereby incorporated by referenced in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls.
(12) As described herein, unless otherwise specified, a container includes a container for a solid, liquid, or gaseous material. The container may be manufactured from a plastic such as polyethylene terephthalate (PETE), high density polyethylene (HDPE), low density polyethylene (LDPE), polyvinyl chloride (PVC), polypropylene (PP), polycarbonate (PC), polylactide, etc., or another suitable material.
(13) An embodiment of the present teachings can provide a container such as a bottle, jug, flask, etc., that has increased resistance to compressive forces. The compressive forces may be, for example, top loading forces applied when stacking at least a second container, more than one container, or one or more other articles, onto a first container. A compressive force may also result from another source, such as a contraction of a material within a sealed container during use. A compressive force may also result from side loading applied by an article adjacent to the container. Further, while the container is generally described with reference to compressive forces, a container according to one or more embodiments as described may have increased resistance to expansive forces from, for example, an expanding material within the container during increasing or decreasing temperatures.
(14)
(15) A container 10 in accordance with the present teachings further includes one or more discrete (e.g., separate, unconnected) vertically oriented sidewall panels or ribs 26 as depicted in
(16) As depicted in
(17)
(18) The sidewall panel 26 can extend into the container 10 for a distance that will depend, for example, on the size and shape of the container 10. The distance can therefore be normalized for any given container. In an embodiment, a recessed sidewall panel 26 can extend into the container 10 for a first distance a, where a is measured from a reference point on the sidewall 20 that is on or immediately adjacent to the perimeter 29 at the midline of the sidewall panel 26, to the point where the sidewall panel 29 is closet to the axis 28. In this embodiment, the axis 28 is perpendicular to the base 12 and intersects the base 12 at the midpoint of the base 12. The first distance a can be compared to a second distance b, where b is the distance from the reference point to the axis 28. For example, a sidewall panel 26 for a specific container 10 may extend into the container 10 for a distance of 5.0 mm (a=5.0), while the distance from the reference point on the sidewall 20 to the axis 28 is 10 mm (b=10). In this specific instance, the normalized distance would equal a/b, or 0.5 (i.e., 50%). In an embodiment, a/b may be from about 0.5% to about 50%, or from about 1% to about 15%, or from about 10% to about 50%, or from about 25% to about 50%.
(19)
(20) Thus as depicted in
(21) In an embodiment, the one or more sidewall panels can include a non-flat pattern within the sidewall panel perimeter 29 to further increase resistance to compressive forces such as top loading forces.
(22) The sidewall panel patterns 42, 48 and sidewall panel 40 may maintain the arc of the continuous arcing profile over the entire height of the sidewall panels and thus are not flat. Therefore, the sidewall panels as depicted in
(23)
(24) Additionally, the sidewall panels and sidewall patterns described herein may improve the gripability of the container by providing a plurality of recessed or raised sidewall panels that aid gripping of the container. Additionally, the inclusion of sidewall pattern 52 may further improve gripability of the container 50.
(25) Each sidewall panel as described herein has a height that is more than 30% of a height of the container sidewall, or more than 50% of the height of the container sidewall, or more than 75% of the height of the container sidewall, or more than 90% of the height of the container sidewall. Each sidewall panel as described herein may further have a height that is more than 30% of a height of the container, or more than 50% of the height of the container, or more than 75% of the height of the container, or more than 90% of the height of the container. Different sidewall panels on the container may have different heights. For example, in a container having four separate sides separated from adjacent sides by a square or rounded edge, sidewall panels near the edges of the container where two sides intersect may have a shorter height than sidewall panels near the center of the sides of the container, for example because the structure of the edges themselves have an increased resistance to compression loading.
(26) In an embodiment,
(27) If the interior of the container is on the right of the
(28) The vertically oriented sidewall panels as described herein may further provide other functionality. For example,
(29) In another aspect, an embodiment of the present teachings may include a container having a steep shoulder 18 (
(30) The container can be manufactured by one of ordinary skill in the art from the description herein using conventional manufacturing techniques. Manufacturing techniques may include, but are not limited to, extrusion blow molding, plastic injection stretch blow molding, etc. Manufacturing techniques may include the use of plastic preforms, a reheat stretch blow molder, etc.
(31) A plastic container in accordance may have a sidewall thickness, including a panel wall thickness, of from about 0.1 millimeters (mm) to about 2 mm, or from about 0.3 mm to about 1.0 mm. Embodiments may thus provide a container having a thin plastic shell to reduce weight and material, for example, to decrease shipping costs, material costs, and environmental impact from discarded containers. While the plastic shell may be thin, the inclusion of sidewall panels as described herein improve the resistance of the container to top and side loading forces.
(32) Thus a container in accordance with the present teachings can include one or more of the features described above that render a container more resistant to compressive or expansive forces, such as side loading forces and/or top loading forces, than conventional container designs.
(33) Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the present teachings are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Moreover, all ranges disclosed herein are to be understood to encompass any and all sub-ranges subsumed therein. For example, a range of less than 10 can include any and all sub-ranges between (and including) the minimum value of zero and the maximum value of 10, that is, any and all sub-ranges having a minimum value of equal to or greater than zero and a maximum value of equal to or less than 10, e.g., 1 to 5. In certain cases, the numerical values as stated for the parameter can take on negative values. In this case, the example value of range stated as less than 10 can assume negative values, e.g. 1, 2, 3, 10, 20, 30, etc.
