Abstract

A handle useful in combination with a container includes a plastic strap or bail and a plastic sleeve thereon. The bail or strap of the handle is pivotably connected to the container, and the sleeve can be rotated about the bail. Structures are provided to distribute load forces between the bail and sleeve. Structures are also provided to retain the sleeve along the longitudinal axis of the bail. One or more clip members can be provided on the bail to engage the container. The clip member includes positioning elements to locate and engage the handle in a selected position with respect to the container. Preferred methods for assembling and using the apparatus (including the combination of the handle and container) are disclosed.

Claims

1. The combination of a container and a handle for a container, said handle including a plastic bail and a plastic sleeve member that includes at least one monolithic tube portion around at least a portion of said bail, said sleeve member providing a gripping surface for manipulating said container, in which said bail has a first end and a second end, and said bail includes a clip member adjacent at least one of said ends for engaging with said container, said clip member having an elliptical cross-section.

2. The combination of a container and a strap member for transporting said container, wherein said strap member includes an elongated section having at least one load-distributing structure thereon for distributing load forces between said strap member and a surrounding generally cylindrical sleeve member, and clip means formed on said strap member, said clip means having an elliptically shaped stem having at least one rib element thereon to provide selectable positioning of said strap member when said strap member is engaged with said container.

3. The combination of a container and a clip element on an elongated container handle strap member wherein said clip element includes a wide portion and a narrow portion situated between said wide portion and said strap member, wherein said narrow portion includes at least one rib element thereon to provide selectable positioning of the handle with respect to said container on which it is engaged.

4. The combination of a container and a clip element to engage a handle with said container, wherein said clip element includes a narrow portion and a wide portion, said narrow portion having a non-circular cross-section to provide greater strength to said clip element in the direction of load normally applied to the handle, wherein said narrow portion of said clip element is elliptical in cross section.

5. The combination of a container and a strap member for transporting said container wherein said strap member includes at least one load-distributing structure for distributing load forces between said strap member and a surrounding generally cylindrical sleeve member;

and clip means having an elliptically shaped stem having at least one rib element thereon to provide selectable positioning of said strap member when said strap member is engaged with said container.

6. A strap assembly for carrying a container, including an elongated strap member having relatively flexible portions at its extremities and a relatively inflexible portion between its extremities, a generally cylindrical sleeve member configured to overlay at least a part of said relatively inflexible portion of said strap member, said sleeve member also being rotatable about a lengthwise axis of said relatively inflexible portion of said strap member.

7. The strap assembly of claim 6, further including cooperating elements on said strap member and sleeve member to prevent inadvertent axial movement of said sleeve member along said lengthwise axis of said strap member.

8. The strap assembly of claim 6, in which said relatively flexible portions of said strap member have a generally rectangular cross-section, said sleeve member includes an interior surface that is generally round, and said relatively inflexible portion of said strap member includes at least one bearing surface extending beyond the shape of said generally rectangular cross-section, said bearing surface shaped to rotatably mate with at least a portion of said interior surface of said sleeve member.

9. The assembly of claim 8, in which said inflexible portion includes a plurality of generally circular disks generally perpendicular to said lengthwise axis of said strap member, said disks sized and configured to fit within the interior of said sleeve member when said sleeve member is positioned therearound, said at least one bearing surface including at least one of said disks.

10. The assembly of claim 9, in which said inflexible portion includes stiffening ribs between said plurality of disks, said stiffening ribs being generally parallel to said lengthwise axis of said strap member.

11. A method of assembling the strap assembly of claim 6 or claim 7 or claim 8 with a container, including inserting one of said relatively flexible portions of said strap member through said sleeve member, sliding said sleeve member into position over said relatively inflexible portion of said strap member, flexing at least one of said relatively flexible portions of said strap member to position its end adjacent said container, and engaging said end with cooperating structure on said container.

12. The combination of a container, an elongated plastic bail attached to said container, and a plastic sleeve member rotatably positioned around a central portion of said bail, said plastic bail having at least one generally flexible end portion to permit selective assembly of said sleeve onto said bail and removal of said sleeve from said bail.

13. The combination of a generally flexible strap and a cooperating sleeve, in which said strap includes engagement structures at its extremities for engaging said strap to a container, said strap configured so that at least approximately one half of said strap including said engagement structure thereon can pass through said sleeve, said sleeve thereby being positionable approximately midway along said strap, said sleeve being rotatable upon said strap when so positioned along said strap.

14. The combination of claim 13, further including cooperating elements on said strap and said sleeve to maintain said sleeve at said position approximately midway along said strap.
