The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/962,960 filed Aug. 2, 2007 entitled ERGONOMIC SYSTEM FOR HANDLING A BUCKET which is hereby incorporated by reference in its entirety.
FIELD OF THE DISCLOSUREThe present invention relates generally to systems for handling containers, and more specifically to an ergonomically improved system of hand carrying and controlling containers.
BACKGROUND OF THE DISCLOSUREContainers, such as standard paint buckets as an example, offer very little means for flexibility of use or ergonomic optimization of control. Among the difficulties presented by the standard container, such as a paint bucket, are limitations in how the container may be held. The standard bucket can generally only be held by the handle, with the handle positioned generally vertical and above the weight of the container. This offers no practical means of supporting the container from below or underneath with a single hand, since that hand is being used to carry the bucket via the handle positioned above the mass of the container.
Prior art devices have attempted to overcome some of these difficulties, but have not been completely successful as they yield varying levels of effectiveness relative to consumer acceptance and true ergonomic improvement. Many previous attempts have resulted in containers which may be difficult to use and manipulate, and may have limited market potential to either after-market applications (stand alone item typically purchased as ancillary assist tool) or as OEM (original equipment manufacturing) products sold directly to paint or coatings manufacturers to be filled with product, labeled and readied for sale. A typical OEM configuration may be a one gallon (or thereabouts) paint can filled with paint, labeled with appropriate information for the specific paint and brand, and intended for sale on retail shelves. An example of such a prior art OEM paint can is the “Twist & Pour Container” by Dutch Boy, a brand by Sherwin Williams. The Dutch Boy “Twist & Pour Container” is a plastic paint container having an integrally molded and defined side handle. This design has many disadvantages, including at least the inability to hold the container from above, the relatively small gripping area of the handle, and the inability of the container to function as a practical or marketable design for after-market sales.
An example of an after-market prior art container is the “Handy Paint Pail” manufactured by Bercom, Inc. which provides a side handle on the side exterior of the container. However, the Handy Paint Pail may not be practically adapted to OEM applications, and it does not incorporate product features which adequately address many important ergonomic issues and dynamics.
An improved ergonomic system for handling a container is desired for both OEM and after-market applications.

For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the disclosure as illustrated therein are contemplated as would normally occur to one skilled in the art to which the disclosure relates.
The present disclosure is generally directed to an ergonomic system for handling a container. In certain embodiments, the ergonomic system is a three-part system incorporating a flexible thumb handle, a contoured palm grasping area, and a finger pocket. The handle, palm grasping area and finger pocket may be substantially vertically aligned down the side of the exterior of the container. The different components of the presently disclosed system together function to distribute the weight of the container (and the material therein) across the user's hand, providing the user the ability to hold the container in an ergonomic and stable manner with one hand.
Referring generally to
More specifically, container body 12 consists of a side wall 30 and a bottom 32. Side wall 30 includes an exterior surface 30a, an interior surface 30b, and a top surface 30c for coupling with lid 16 (see
Side wall 30 defines a top opening 40 in communication with the interior cavity 42 defined by the container body (see
In an alternative optional embodiment, the lid may be hingedly attached to the container body. In this way, the lid can be easily moved between open and closed positions. Additionally, flipping the lid to the closed position via the hinged connection may help to seal the container's contents from atmospheric conditions, to avoid effects such as skimming over of paint. In another alternative optional embodiment, the lid may be configured to be used as a stand for which to place the container body on. As such, the lid may be removed from the top of the container and coupled to the underside of the container to function as a stand. In yet another alternative optional embodiment, the lid may include one or more openings configured to receive a paint brush handle and hold or suspend the paint brush from the lid. In particular embodiments, the opening may include a perforated rubber or flexible plastic cover to engage the brush handle and hold it in the suspended position.
Container 10 includes handle attachment features 44 disposed on exterior surface 30a (see
In preferred embodiments, handle 14 is flexible and conformable. As an example, handle 14 may be comprised of a flexible plastic material 48, such as low density polyethylene. In alternative embodiments, handle 14 may be padded with a cushioning material wrapped around a flexible metal or plastic wire. Handle 14 is preferably sufficiently flexible such that it at least slightly molds or conforms to the user's thumb area. As illustrated in
As best illustrated in
As best illustrated in
Palm grasping area 20 allows for a substantial portion of the user's palm to press securely against the side exterior of the container when the user is also utilizing the flexible thumb handle and the finger pocket. When used in this way, the palm of the user's hand acts as a stabilizing surface in the proximity of the container's center of gravity, which can aid in distributing evenly the weight of the material in the container throughout the user's hand. In preferred embodiments, the palm grasping area 20 is contoured for ease of gripping by the palm of the user's hand. As particular examples, area 20 may be curved or rounded. Accordingly, in certain embodiments, the container wall 30 is substantially cylindrical in shape with a circle cross-section along area 20. However, it is contemplated that in other embodiments the container wall and thus the container body may be shaped, sized and configured differently than as illustrated. As an example, in alternative embodiments, the container wall may be square in cross-sectional shape.
During use, a user may implement the three-part system to handle and control container 10. Accordingly, the user may grab handle 14 with their thumb, place the palm of their hand (and optionally one or more fingers) against exterior surface 30a in palm grasping area 20, and insert one or more fingers in the finger pocket 18 such that the fingers contact the top surface 63. More specifically, the handle is laid along the side exterior of the container and the user's thumb is inserted between the handle and the side exterior of the container and then at least slightly wrapped around the handle. The flexibility of the handle enables the user to wrap their thumb at least slightly around the top of the handle to provide a customized and secure fit against the side of the container.
Accordingly, the user may hold the container with one hand by distributing the weight of the container and the material in the container throughout the user's hand. In a particular embodiment, the user's palm, index finger, and middle finger are placed against the exterior surface and the user's ring finger and little (or pinky) finger are inserted in the finger pocket cavity. The presently disclosed system allows the user to hold the container in a stable and ergonomic manner with one hand. Additionally, the presently disclosed system allows the user to hold the container substantially from the bottom or from a position below the majority of the mass of the container, rather than holding the container from above via a handle or another mechanism. Further, the finger pocket allows the user to set the container down on a support surface without the fingers being disposed between the container and the surface, enabling a smoother transition without need for the user's other hand to assist in setting the container on the support surface.
Alternatively, it is contemplated that the system for handling a container according to the present disclosure may include only one or two of the three features described above as part of the three-part ergonomic system, with one or two of the other features being absent. For example, in one alternative embodiment, the container may include a finger pocket, but the palm grasping area and the thumb handle may be absent.
Additionally, it is contemplated that the containers according to the present disclosure may be designed and configured for use as after-market containers or OEM products. In an example embodiment in which the containers according to the present disclosure are paint cans, the containers may be after-market paint containers purchased in addition to paint provided in a typical or prior art paint can. In such embodiments, the paint may be poured into the containers and used as desired after purchasing the paint and the containers separately. In another example embodiment in which the containers according to the present disclosure are paint cans, the containers may be OEM (original equipment manufacturing) products which are sold to or otherwise provided to, or alternatively manufactured by, paint manufacturers, filled with paint products by the paint manufacturers, labeled with appropriate information identifying the specific paint and brand, and readied for sale.
While the disclosure has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
