Abstract
A composite pressure sensitive adhesive construction has an adhesive portion located laterally on each side of a carrier. The central portion of the carrier is free from adhesive. A split release liner covers each adhesive portion. In use, the adhesive construction can be applied to any article, for example an insulation tube, and especially articles having a split or opening so that the article can be secured in a closed position. Moreover, the adhesive construction can have one laterally adhesive portion applied to the article, with the remaining adhesive portion having the release liner thereon which is readily removed and the remaining adhesive portion securely engaged to the article.
Claims10
An article having a longitudinal split therein and an adhesive construction thereon, comprising:
- the article and the adhesive construction,
- said adhesive construction having a single carrier layer, said carrier layer having two separate areas of an adhesive located on one side thereof at the lateral portions thereof and a central portion free from said adhesive located between said lateral portions,
- one of said lateral adhesive portions of said carrier layer adhered to said article adjacent to said split, said second lateral adhesive portion of said same carrier layer non-adheringly located adjacent to said remaining split portion of said article, and said adhesive-free portion overlying said split portion,
- said adhesive carrier layer having a single release liner, said release line attached to said second lateral adhesive portion, said release liner extending into said adhesive-free area and forming a tab.
A process for attaching an adhesive construction to an article having a slit therein, comprising the steps of:
- removing a release linear from a lateral portion of an adhesive construction having a single carrier layer, said carrier layer having two separate areas of an adhesive located on one side thereof at the lateral portions thereof so that a central adhesive-free portion exists,
- applying said exposed laterally adhesive portion of the adhesive construction to an edge of said slit so that said central adhesive-free portion overlies said slit, said carrier having a central area free from adhesive, said remaining adhesive portion having a single release liner thereon extending into said adhesive-free area and forming a tab.
A rolled adhesive having a construction consisting essentially of
- a single carrier layer, said carrier layer having longitudinal lateral adhesive portions thereon to leave a central area located between said longitudinal lateral portions, said central area being free from adhesive, and
- separate longitudinal release liners, each said separate release liner being located on one of said lateral adhesive portions, each said separate liner extending into and overlapping a portion of said central adhesive-free area.
