Open the CIPO recordAbstract From the Canadian patent
A wraparound sleeve has closure members typically, in the form of upstanding rails at its longitudinal, edges. A channel having a discontinuity along its length is positioned over the closure members to hold the sleeve in a closed configuration. A clip is positioned between the closure members and the channel to bridge the discontinuity in the channel. The discontinuity in the channel preferably extends through the channel entirely, so that the channel is in two or more parts, which can be installed end to end. The discontinuity in the channel aids installation particularly where the closure to be formed is of long length.
