Abstract
Abstract 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. This application is a continuation of application Ser. No. 920,493, filed Oct. 17, 1986, now abandoned, which is a continuation of application Ser. No. 071,536, filed July 9, 1987, now abandoned.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
An assembly for environmentally sealing a substrate which comprises: a wraparound dimensionally-recoverable sleeve having closure members comprising rails hoving bases with the rails undercut at their respective bases adjacent opposing edge portions thereof, which members can be held together to hold the sleeve in a wrap-around configuration; an elongate closure channel that is generally cshaped in transverse cross-section and is positioned over the closure members thereby holding them together and being resistant to lateral removal therefrom due to its c-shape, the channel having a discontinuity along its length, the discontinuity extending through the channel entirely such that the channel is in two or more separate parts which may be positioned end-to-end, each over both closure members; and a clip installed over and gripping both closure members at a position between the channel and the closure members and bridging the discontinuity in the channel.
Claim 2
Dependent Claim
143 words
An assembly for environmentally sealing a substrate which comprises: a wraparound dimensionally-recoverable sleeve having closure members comprising rails hoving bases with the rails undercut at their respective bases adjacent opposing edge portions thereof, which members can be held together to hold the sleeve in a wrap-around configuration; an elongate closure channel that is generally cshaped in transverse cross-section and is positioned over the closure members thereby holding them together and being resistant to lateral removal therefrom due to its c-shape, the channel having a discontinuity along its length, the discontinuity extending through the channel entirely such that the channel is in two or more separate parts which may be positioned end-to-end, each over both closure members; and a clip installed over and gripping both closure members at a position between the channel and the closure members and bridging the discontinuity in the channel.
Claim 3
Dependent Claim
18 words
An assembly according to claim 1, in which the sleeve has an internal layer of a sealing material.
Claim 4
Dependent Claim
25 words
An assembly according to claim 1, in which the clip comprises a resiliently deformable material, said clip installed by snap fitting over the closure members.
Claim 5
Dependent Claim
92 words
An assembly for environmentally sealing a substrate which comprises: a wraparound dimensionally recoverable sleeve having opposed edge closures members, said edge closure members capable of being held together in a wraparound sleeve configuration by a c-shaped elongate closure channel; at least two substantially c-shaped elongate closure channels, said closure channels can be positioned over said closure members thereby holding said closure members together and being resistant to lateral removal therefrom; and a clip installed over and gripping said closure members at a position between said closure channels to bridge said closure channels.
Claim 6
Dependent Claim
92 words
An assembly for environmentally sealing a substrate which comprises: a wraparound dimensionally recoverable sleeve having opposed edge closures members, said edge closure members capable of being held together in a wraparound sleeve configuration by a c-shaped elongate closure channel; at least two substantially c-shaped elongate closure channels, said closure channels can be positioned over said closure members thereby holding said closure members together and being resistant to lateral removal therefrom; and a clip installed over and gripping said closure members at a position between said closure channels to bridge said closure channels.
Claim 7
Dependent Claim
24 words
An assembly according to claim 4, wherein said clip comprises a resiliently deformable material permitting said clip to be snap-fit over said closure members.
Claim 8
Dependent Claim
22 words
An assembly according to claim 4 wherein said clip includes opposing upturned edges capable of accepting the opposing edges said closure members.
Claim 9
Independent Claim
77 words
A method of environmentally sealing a substrate which comprises: positioning around the substrate the opposing edge portion closure members of a dimensionally recoverable sleeve, said closure members shaped to accept a clip and at least two substantially cshaped elongate closure channels; positioning said clip on said closure members so that said clip can contact the closure channels and grip the closure members; and positioning the closure channels on said closure members in bridging contact with said clip.
Claim 10
Independent Claim
77 words
A method of environmentally sealing a substrate which comprises: positioning around the substrate the opposing edge portion closure members of a dimensionally recoverable sleeve, said closure members shaped to accept a clip and at least two substantially cshaped elongate closure channels; positioning said clip on said closure members so that said clip can contact the closure channels and grip the closure members; and positioning the closure channels on said closure members in bridging contact with said clip.
Claim 11
Dependent Claim
28 words
The method according to claim 7 wherein said clip snap-fits over said closure members and said closure channels slide along said closure members into bridging contact said clip.
