Abstract

Abstract A closing arrangement for a packing container is disclosed including a tubular member that may be firmly anchored within a pouring opening of the container. A cap member closes the tubular member and is provided with a pull-ring. The cap member is joined to the tubular member by a first connecting member which may be broken to open the container. The cap member is also joined to the tubular member by a second connecting member which forms a hinge located diametrically opposite to the pull ring. The second connecting member retains the cap member on the tubular member after the container is opened. The pull ring includes a locking element which cooperates with the tubular member to provide a catch. Upon movement of the pull-ring to open the container, the catch is caused to disengage from the tubular member. In this way, the first connecting element is broken but the catch permits a reclosure of the container. The closing arrangement is preferably made of a plastic material especially polyolefin.

Claim 1
Independent Claim 145 words
A packing container having a closure, comprising: a container having a first opening; an annular member securely received within the first opening to define a second opening, said annular member having a flange attached to an upper surface of the annular member, said flange extending outwardly from the container; cap means for closing the second opening; pull means for permitting the cap means to be manually moved relative to the second opening; first connecting means for sealingly joining the cap to the annular member at the second opening, said first connecting means being broken when the cap means is moved manually relative to the second opening; hinge means for attaching the cap means to the annular member; and catch means for engaging the annular flange to releasably fix the cap means with respect to the container whereby the packing container may be reclosed after opening.
