Abstract
Abstract An improved carrier tape is disclosed comprising a cover strip and a base strip formed of a plastic material and designed to mechanically interlock with each other. The cover strip includes a top surface from which opposed sidewalls extend downwardly. The cover strip is further provided with a pair of longitudinally extending humps which project upwardly from the top face. The humps are generally semi-circular in cross-section and are positioned adjacent the edges of the cover strip, spaced inwardly of the sidewalls. The humps define living hinges for the adjacent surfaces of the cover strip top face and the sidewalls so that when the humps are depressed the sidewalls move laterally outwardly.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
116 words
A carrier tape comprising: an elongated base strip; an elongated cover strip formed of a resilient plastic material substantially coextensive in length with said base strip, said cover strip having a top surface and opposed sidewalls extending downwardly from the top surface and spaced apart from each other a distance substantially equal to the width of said base strip and cooperating to secure said cover strip to said base strip; and, a pair of humps defined in said top surface projecting upwardly from the top surface and extending longitudinally, parallel to said sidewalls, whereby when said humps are depressed said sidewalls move outwardly, away from each other to release said cover strip from said base strip.
Claim 2
Dependent Claim
116 words
A carrier tape comprising: an elongated base strip; an elongated cover strip formed of a resilient plastic material substantially coextensive in length with said base strip, said cover strip having a top surface and opposed sidewalls extending downwardly from the top surface and spaced apart from each other a distance substantially equal to the width of said base strip and cooperating to secure said cover strip to said base strip; and, a pair of humps defined in said top surface projecting upwardly from the top surface and extending longitudinally, parallel to said sidewalls, whereby when said humps are depressed said sidewalls move outwardly, away from each other to release said cover strip from said base strip.
Claim 3
Dependent Claim
45 words
The carrier tape in accordance with claim 1 wherein each of said sidewalls terminates in an inwardly directed barb projecting beneath said base strip, said barbs extending a distance such that when said humps are depressed said barbs move outwardly to clear said base strip.
Claim 4
Dependent Claim
23 words
The carrier tape in accordance with claim 1 wherein said base strip includes a plurality of longitudinally spaced, downwardly extending component cavities therein.
Claim 5
Dependent Claim
31 words
The carrier tape in accordance with claim 3 wherein said base strip includes two rows of longitudinally spaced sprocket holes extending therein, said rows being on opposite sides of said cavities.
Claim 6
Dependent Claim
40 words
The carrier tape in accordance with claim 4 wherein one of said humps is aligned over one of said rows of sprocket holes and the other of said humps is aligned over the other of said rows of sprocket holes.
