Abstract
A container carrier and manufacturing method therefor are provided. The container carrier may include an integrally molded body with a top surface, a bottom surface, and a plurality of annular structures. Each annular structure may connect to at least one adjacent annular structure and may include a circumferential rib with a plurality of flanges, which are collectively configured to secure a container. An integrally formed handle may extend upward from the body of the container carrier. The handle may include a graspable region and a bifurcated region that forms a pair of arms that connect to the body and support the graspable region in an upright configuration in an unbiased state. The arms may flex such that an intersection of the bifurcated region and graspable region moves to accommodate a downward flexion of the handle when a downward biasing force is applied to the handle in a biased state.

DETAILED DESCRIPTION
[0032] Selected embodiments of the present disclosure will now be described with reference to the accompanying drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the disclosure are provided for illustration only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.
First Embodiment
[0033] Turning to the figures,
[0034] Each annular structure 16 may be connected to at least one adjacent annular structure 16 of the plurality of annular structures 16 by a bridge 34 and may include a circumferential rib 18. A plurality of flanges 20 may be coupled to the circumferential rib 18. Each flange 20 may further include an inwardly projecting portion 22. In the present embodiment, eight flanges 20 are provided in each annular structure 16, but it will be appreciated that the number of flanges 20 in the annular structures 16 may be more or less than illustrated, so long as their shape and position are sufficient to releasably secure a container.
[0035] An inner perimeter 24 of each flange 20 may be formed to have an arcuate shape. Collectively, the inner perimeters 24 of the flanges 20 may be configured to define a void 26. Further, the void 26 defined by the arcuate inner perimeters 24 of the flanges may be formed to have a circular perimeter 28. The circular perimeter 28 of the void 26 may be centered on a vertical central axis C of the annular structure 16. A container may be inserted into void 26, and the flanges 20 may collectively secure the container therein.
[0036] An integrally formed handle 30 may extend in an upward orientation from the body 10 of the container carrier 100. A shape of the curve of the handle 30 may be concave down when the handle is in an upright configuration in an unbiased state, and the shape of the curve of the handle may be concave up when the handle is in a deflected configuration in a biased state.
[0037] As shown in
[0038] As shown in the illustrated embodiment, the handle 30 may be formed to further include a bifurcated region 38, enclosed in dashed lines in
[0039] The arms 40a, 40b may be formed to include respective straight regions 42a, 42b and respective curved regions 42c, 42d. The straight regions 42a, 42b are positioned adjacent an intersection 44 of the bifurcated region 38 and the graspable region 36. As the arms 40a, 40b approach a horizontal plane in which the top surface 12 of the container carrier 100 is arranged, the straight regions 42a, 42b may flare out into respective curved regions 42c, 42d before connecting to the body 10 of the container carrier 100. This configuration allows the arms 40a, 40b to flex when a force is applied, which permits the shape of the handle 30 to distort while remaining anchored to the body 10 of the container carrier 100. Specifically, when a downward biasing force is applied to the handle 30 in a biased state, the pair of arms 40a, 40b flexes to allow the intersection 44 between the bifurcated region 38 and graspable region 36 to move such that a downward flexion of the graspable region 36 of the handle 30 can be accommodated. For example, when an item pushes down on or is stacked on top of a container carrier 100, the straight regions 42a, 42b of the pair of arms 40a, 40b flex away from the graspable region 36, as indicated by the dashed lines in
[0040] The above-described bifurcated region 38 and arms 40a, 40b may be designated as a first bifurcated region 38a and a first pair of arms 40a, 40b, and the handle 30 may further include a second bifurcated region 38b that bifurcates into a second pair of arms 40c, 40d. As illustrated by the dash-dot line in
[0041] The first and second pairs of arms 40a, 40b, 40c, 40d may flex to allow the respective first and second intersections 44a, 44b to move, thereby accommodating a downward flexion of the graspable region 36 of the handle 30 when a downward biasing force is applied to the handle 30 in a biased state. Such flexing of the first and second pairs of arms 40a, 40b, 40c, 40d causes the first and second intersections 44a, 44b to move away from each other, thereby increasing a distance D between the first and second bifurcated regions 38a, 38b to accommodate passage of the graspable region 36 between the first and second bifurcated regions 38a, 38b as viewed from above, and through a plane P of the body 10, as viewed from a side. One embodiment of the handle 30 in a deflected configuration after passage of the graspable region 36 through the plane P of the body 10 is illustrated by the dash-dot line in
[0042] Turning now to
[0043]
[0044] To releasably engage the containers CON in the container carrier 100, the flanges 20 included in each annular structure 16 may be configured to flex independently during ingress or egress of one of the containers CON into or out of the corresponding void 26. In an unflexed state, the flanges 20 may be collectively configured to conform to a curvature of a neck of one of the containers CON. The flanges 20 are thus configured to releasably engage a container CON at the neck, the outer diameter of the neck being smaller than an inner diameter of a lip or a cap CAP of the container CON, as illustrated in
[0045] Turning back to
[0046] Turning to
[0047] Continuing now to
[0048] The container-engaging semi-annular structure 16a may be formed to have a semi-annular shape by including a straight portion in the circumferential rib 18a that is positioned toward an interior void 46 of the body 10 of the container carrier 100. This implementation increases the area of the interior void 46 of the container carrier 100 to provide room for the flexion of the handle 30 as it transitions from an upright position to a deflected position. As discussed above and illustrated in the present embodiment, the circular perimeter 28 of the void 26 may be centered on a vertical central axis C of the annular structure 16 or the container-engaging semi-annular structure 16a. However, it will be appreciated that the circular perimeter 28 of the void 26 may be offset with respect to the annular structure 16 or the container-engaging semi-annular structure 16a.
[0049] The arrangement of the flanges 20 defining a circular perimeter 28 of a void 26 within an annular structure 16 may give rise to a configuration in which the plurality of flanges 20 may have the same lengths. This configuration may be observed in an embodiment of a container carrier 100 in which the annular structure 16 and the circular perimeter 28 of the void 26 are both centered on central vertical axis C. As described above, the container carrier 100 may include one or more container-engaging structures 16a that may be formed to have a semi-annular shape. In this alternate configuration, one or more of the flanges 20 positioned proximate the straight region of the circumferential rib 18a of the container-engaging semi-annular structure 16a may be formed to be shorter than adjacent flanges 20. However, it will be appreciated that the inner perimeters 24 of the flanges 20 may collectively define a void 26 with a circular perimeter 28, regardless of the shape of the container-engaging structure. While the illustrated embodiment includes an even number of flanges 20, with the annular structure 16 and the circular perimeter 28 of the void 26 both centered on the central vertical axis C, it will be appreciated that the configuration of the container carrier 100 is not limited to illustrated embodiment. For example, the flanges 20 may occur in an even or an odd number and may be formed to be equal in length to, or longer or shorter than an adjacent flange 20 to accommodate a desired container size/weight and/or a desired cap size/shape. Further, as discussed above, the circular perimeter 28 of the void 26 may be offset with respect to the annular structure 16 or the container-engaging semi-annular structure 16a.

[0058] In any of the embodiments described herein, the container carrier may be preferentially formed of a flexible plastic. Being both strong and lightweight, plastic is an advantageous material for use in container carriers. It is preferable that the plastic be flexible in nature to accommodate the flexible nature of the handle, as well as the releasable engagement of the containers with the flanges. Specifically, the plastic may be high density polyethylene (HDPE), and it may further be recycled HDPE. It will be appreciated that container carriers formed of flexible plastic have the additional benefit of being recyclable.
[0059] The container carriers described above may be used to provide a convenient carrying mechanism for containers of all sorts, but are particularly advantageous due to the manner in which the handle extends beyond the top of the container carrier. In some circumstances, the caps of the containers secured within the container carrier may possess sharp edges that can cut or damage the skin of the user. The container carriers described herein prevent such an undesirable situation by allowing a user to grasp and carry the container carrier without contacting the caps of the containers secured within the container carrier.
[0060] It should be understood that the embodiments herein are illustrative and not restrictive, since the scope of the invention is defined by the appended claims rather than by the description preceding them, and all changes that fall within metes and bounds of the claims, or equivalence of such metes and bounds thereof are therefore intended to be embraced by the claims.
