DETAILED DESCRIPTION

[0019] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0020] FIG. 1 illustrates a polymeric container in accordance with the present disclosure at reference numeral 10. The container 10 may be made of any suitable polymeric material, such as polyethylene terephthalate (PET), low-density polypropylene (LDPP), high-density polyethylene (HDPE), polypropylene, and polystyrene, for example. The container 10 is formed from a preform, such as by any suitable blow-molding process. The container 10 is configured to store any suitable commodity, such as any suitable hot-fill commodity. Exemplary hot-fill commodities include, but are not limited to, any suitable liquid (e.g., energy drinks, sport drinks, sport supplements, etc.) or any suitable food commodity. The container 10 may have any suitable interior volume, such as 20-32 ounces.

[0021] The container 10 includes a finish 12, which defines an opening 14 of the container 10. Extending from an exterior of the finish 12 are threads 16. The threads 16 are configured to cooperate with any suitable closure to close the opening 14. Extending from an exterior of the finish 12 proximate to the threads 16 is a flange 18, which may be used to support the preform during blow-molding of the container 10.

[0022] Beneath the flange 18 is a neck 20. A dome 30 extends downward and outward from the neck 20, and defines a shoulder 32 of the container 10. Extending from the dome 30 is an upper body portion 40. The upper body portion 40 defines upper ribs 42. Beneath the upper body portion 40 is an intermediate rib 44.

[0023] Extending from the upper body portion 40 is a lower body portion 50. The lower body portion 50 extends to a base 70, which is configured to support the container 10 upright when seated on a suitable support surface. The base 70 is a vacuum-absorbing base. Suitable vacuum-absorbing bases include, but are not limited to, any of the vacuum-absorbing bases disclosed in U.S. patent application Ser. No. 16/164,190 titled “Lightweight Container Base” (filed on Oct. 18, 2018), as well as any of the container bases disclosed in the patents and patent applications related to U.S. patent application Ser. No. 16/164,190, each of which is incorporated herein by reference. A longitudinal axis X extends through an axial center of the opening 14, the finish 12, the dome 30, the upper body portion 40, the lower body portion 50, and the base 70.

[0024] The lower body portion 50 includes a grip area 52. The grip area 52 includes a plurality of grip panels 60A, each of which is surrounded by a border 54. The grip panel 60A may have any suitable shape, such as any suitable polygonal shape. In the example of FIGS. 1 and 2, the grip panels 60A have an oval shape. Other suitable shapes include, but are not limited to, octagonal, rectangular (see FIGS. 3 and 4 at 60B), and polygonal (see FIGS. 5 and 6 at 60C).

[0025] Each one of the grip panels 60A, 60B, and 60C have a height H, a width W, and a depth D. The depth D is a distance that the grip panels 60A are recessed beneath the border 54, which is at an outermost surface of the lower body portion 50. Each grip panel 60A includes a continuous radius surface 62, which continuously curves from the border 54 inward to a bottom or deepest portion of the grip panels 68A, 68B, 68C. The depth D is measured from the border 54 to the bottom or deepest portion of the grip panel.

[0026] The height H of each one of the grip panels 60A is about 55%-65% (or less than 65%) of the width W. The depth D of each one of the grip panels 60A is about 17%-19% (or greater than 17%) of the height H. Each one of the grip panels 60A has a depth D that is 10%-11% of the width W. The grip panels 60B and 60C have the same height H, depth D, and width W ratios as the grip panels 60A. FIG. 9 illustrates exemplary dimensions of various containers 10 in accordance with the present disclosure.

[0027] The grip panels 60A, 60B, and 60C are arranged in rows that extend around the outer circumference of the grip area 52. Any suitable number of rows may be included, such as 2-5 rows. Each row may include any suitable number of grip panels 60A, 60B, or 60C, such as 5-7 grips per row extending about the circumference. The grip panels 60A, 60B, and 60C may be vertically staggered, such as illustrated in FIGS. 1, 3, and 5. Alternatively, the grip panels 60A, 60B, and 60C may be vertically aligned, as illustrated in FIGS. 2, 4, and 6.

[0028] The grip areas 52 with the grip panels 60A, 60B, 60C advantageously increase the rigidity of the container 10 at the grip areas 52 by 30% or more as compared to existing containers, which advantageously increases the dent resistance of the container 10. With reference to FIG. 7, point-load performance of exemplary containers 10 in accordance with the present disclosure is illustrated. Containers 10 in accordance with the present disclosure were subjected to point-load testing. Point-load was simulated using FEA analysis to determine how much force in pounds it would take for a one inch round ball to displace/deform the grip area 52 a distance of 0.3 inches. As illustrated in FIG. 7, it took about 6-8 pounds of force to displace/deform the grip area 52 (of containers 10 having vertically aligned grip panels 60A, 60B, 60C) a distance of 0.3 inches, which means that the grip area 52 is able to withstand about 30% more point-load force than existing containers. FIG. 8 illustrates exemplary point-load performance of containers 10 having grip panels 60A, 60B, 60C that are vertically staggered. As illustrated in FIG. 8, it took about 12 pounds of force to displace/deform the grip area (of containers 10 having vertically staggered grip panels 60A, 60B, 60C) a distance of 0.3 inches. The grip panels 60A, 60B, and 60C also advantageously allow the polymeric material of the container 10 to have a lower material weight and lower thickness while maintaining acceptable point-load performance that resists denting at the grip area 52. One skilled in the art will appreciate that the present disclosure provides numerous additional advantages and unexpected results as well.

[0029] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.

[0030] Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.

[0031] The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.

[0032] When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

[0033] Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

[0034] Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
