Filed:

Appl. No.:

8/121338

Inventors:

Frano Luburic - Fullerton CA
Dennis R. Willis - Corona CA

Assignee:

Ropak Corporation - Fullerton CA

International Classification:

B65D 2532

US Classification:

220760

Abstract:

A container bail incorporates securement means cooperative with retaining means on a container, said securement means having a head receivable in a receptor opening in the retaining means which is of totally different size and configuration from the receptor opening in the securement means which creates an interference fit materially reducing the likelihood of inadvertent dislodgement of the securement means from the retaining means. The bail also incorporates flexibility at critical points which augments the tendency of the retaining means to remain operatively associated with the securement means.

Dennis R. Willis - Corona CA

Assignee:

Ropak Corporation - Fullerton CA

International Classification:

B65D 1740

US Classification:

220276

Abstract:

A container lid is characterized by a tamper-evidencing tear-strip member having a tab that protrudes from a plane formed by adjacent portions of the lid. The tab preferably includes gripping rib members on opposing surfaces of the tab and is surrounded by a sufficient gap to permit the tab to be readily grasped for easier removal of the tear-strip member from the lid, prior to initial removal of the lid from the container. In container and lid embodiments that are substantially rectangular, the lid also preferably includes mating engagement structure between the lid and the container which is interrupted or not present at the corners of the lid. The tear-strip in this rectangular embodiment also preferably includes a widened portion at the corners, whereby the removal of the tear-strip results in a "scalloping" of the corners. These features on rectangular embodiments facilitate easier attachment and removal of the lid to and from the container, after the removal of the tear-strip.
