Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
Adhesive tape for the reclosable closure of a tubular bag or the like, comprising a base coated with a longitudinal line of adhesive and having a tab running in the longitudinal direction of the adhesive tape and laterally extending past said line adjoining the base of adhesive, the tab (3), continues into a tear-open region (4) which, in the manner of an original closure, can be torn open in the longitudinal direction of the adhesive tape (1), and the tear-open region, adjoining the tab, continues into adhesive region (6) coated with another longitudinal line of adhesive, the tear-open region being formed by strong stretching of the base in the longitudinal direction of the adhesive tape.
Claim 2
Dependent Claim
115 words
Adhesive tape for the reclosable closure of a tubular bag or the like, comprising a base coated with a longitudinal line of adhesive and having a tab running in the longitudinal direction of the adhesive tape and laterally extending past said line adjoining the base of adhesive, the tab (3), continues into a tear-open region (4) which, in the manner of an original closure, can be torn open in the longitudinal direction of the adhesive tape (1), and the tear-open region, adjoining the tab, continues into adhesive region (6) coated with another longitudinal line of adhesive, the tear-open region being formed by strong stretching of the base in the longitudinal direction of the adhesive tape.
Claim 3
Dependent Claim
26 words
Adhesive tape according to claim 1, characterized in that the base is a transparent polypropylene plastic film and the longitudinal lines of adhesive is a self-adhesive.
Claim 4
Dependent Claim
20 words
Adhesive tape according to claim 1, characterized in that a beginning of the tear-open region is designed as a tab.
Claim 5
Dependent Claim
27 words
Adhesive tape according to claim 1, characterized in that the tear-open region is underlaid with a tear-open strip running in the longitudinal direction of the adhesive tape.
Claim 6
Dependent Claim
25 words
Adhesive tape according to claim 1, characterized in that the tear-open region has perforations or slits running in the longitudinal direction of the adhesive tape.
Claim 7
Dependent Claim
11 words
A container closed with an adhesive tape according to claim 1.
Claim 8
Dependent Claim
60 words
A container according to claim 6, wherein the container is a tubular bag having a longitudinal row of weak points, the base of the tape being affixed over such weak points, tearing of the base exposing the tab for opening, which opening tears the bag along the row of weak points, the torn line being visible even upon subsequent resealing.
Claim 9
Dependent Claim
67 words
A tape for the reclosable closure of a container having two spaced lines of adhesive, and a weakened tear strip between and spaced from at least one of the adhesive lines so that when the tear strip is torn from the tape there remains an adhesive-free strip laterally extending from said at least one of the adhesive lines for facilitating the opening and re-sealing of said container.
Claim 10
Dependent Claim
67 words
A tape for the reclosable closure of a container having two spaced lines of adhesive, and a weakened tear strip between and spaced from at least one of the adhesive lines so that when the tear strip is torn from the tape there remains an adhesive-free strip laterally extending from said at least one of the adhesive lines for facilitating the opening and re-sealing of said container.
