Abstract
Abstract A unitary flexible carrier tape comprising a strip like portion defining a top surface for the tape, and wall portions defining a multiplicity of similarly shaped pockets spaced along the tape and opening through the top surface. Side wall portions extending between the strip like portion and bottom wall portions to define the pockets include a majority of angled parts disposed at included angles of slightly greater than a right angle with respect to the top surface of the strip like portion so that the angled parts of the side wall portions converge toward the bottom wall portions defining the pockets, and a minority of generally normal parts extending between the strip like portion and the bottom wall portions that are disposed at included angles significantly closer to a right angle with respect to the top surface of the strip like portion than the included angles between the top surface of the strip like portion and the adjacent angled parts to provide, with projecting parts of the bottom wall portions adjacent the generally normal parts, anti nesting shoulders for restricting entry of the side wall portions defining the pockets in one wrap of the carrier tape on a reel into the pockets in the wrap of carrier tape beneath it.

Claim 1
Independent Claim
213 words
A unitary flexible carrier tape comprising a strip like portion defining a top surface for said tape, and wall portions defining a multiplicity of similarly shaped pockets spaced along said tape and opening through said top surface, said wall portions comprising: bottom wall portions, side wall portions extending between said strip like portion and said bottom wall portions, said side wall portions including: a majority of angled parts disposed at included angles of slightly greater than a right angle with respect to the top surface of said strip like portion so that said angled parts of said side wall portions converge toward the bottom wall portions, and a minority of generally normal parts extending between said strip like portion and said bottom wall portions, said generally normal parts being disposed at included angles significantly closer to a right angle with respect to the top surface of said strip like portion than the included angles between said adjacent angled parts and said top surface to provide, with projecting parts of said bottom wall portions adjacent said generally normal parts, anti nesting shoulders for restricting entry of said side wall portions defining the pockets in one wrap of the carrier tape on a reel into the pockets in the wrap of carrier tape beneath it.
Claim 2
Dependent Claim
213 words
A unitary flexible carrier tape comprising a strip like portion defining a top surface for said tape, and wall portions defining a multiplicity of similarly shaped pockets spaced along said tape and opening through said top surface, said wall portions comprising: bottom wall portions, side wall portions extending between said strip like portion and said bottom wall portions, said side wall portions including: a majority of angled parts disposed at included angles of slightly greater than a right angle with respect to the top surface of said strip like portion so that said angled parts of said side wall portions converge toward the bottom wall portions, and a minority of generally normal parts extending between said strip like portion and said bottom wall portions, said generally normal parts being disposed at included angles significantly closer to a right angle with respect to the top surface of said strip like portion than the included angles between said adjacent angled parts and said top surface to provide, with projecting parts of said bottom wall portions adjacent said generally normal parts, anti nesting shoulders for restricting entry of said side wall portions defining the pockets in one wrap of the carrier tape on a reel into the pockets in the wrap of carrier tape beneath it.
Claim 3
Dependent Claim
29 words
A carrier tape according to claim 1 wherein successive pockets having anti nesting shoulders along said tape have the anti nesting shoulders located adjacent opposite sides of said tape.
Claim 4
Dependent Claim
56 words
A carrier tape according to claim 2 wherein every set of four successive pockets along said tape includes a pocket having an anti nesting shoulder adjacent one side of said tape, a pocket having an anti nesting shoulder adjacent the side of said tape opposite said one side, and a pocket without an anti nesting shoulder.
Claim 5
Dependent Claim
27 words
A carrier tape according to claim 1 wherein each of said pockets along said tape has two anti nesting shoulders, one adjacent each side of said tape.
Claim 6
Dependent Claim
25 words
A carrier tape according to claim 4 wherein said two anti nesting shoulders in each of said pockets are adjacent opposite corners of said pockets.
Claim 7
Dependent Claim
42 words
A carrier tape according to claim 1 wherein said generally normal parts of the side walls that form said anti nesting shoulders do not form over fifty percent of the side walls along any one side of any one of the pockets.
Claim 8
Dependent Claim
43 words
A carrier tape according to claim 1 wherein said generally normal parts of the side walls that form said anti nesting shoulders do not form over about 30 percent of the side walls along any one side of any one of the pockets.
Claim 9
Dependent Claim
66 words
A carrier tape according to claim 1 wherein said angled parts are disposed at included angles in the range of about 93 to 98 degrees with respect to the top surface of said strip like portion, and said generally normal parts are disposed at included angles in the range of about 89 to 91 degrees with respect to the top surface of said strip like portion.
Claim 10
Dependent Claim
55 words
A carrier tape according to claim 8 wherein said angled parts are disposed at included angles of about 95 degrees with respect to the top surface of said strip like portion, and said normal parts are disposed at included angles of about 90 degrees with respect to the top surface of said strip like portion.
Claim 11
Dependent Claim
37 words
A carrier tape according to claim 1 wherein said generally normal parts are disposed at included angles in the range of about 89 to 91 degrees with respect to the top surface of said strip like portion.
Claim 12
Dependent Claim
31 words
A carrier tape according to claim 1 wherein said anti nesting shoulders are generally in the shape of a portion of a cylinder having an axis perpendicular to said top surface.
Claim 13
Dependent Claim
41 words
A carrier tape according to claim 1 wherein said anti nesting shoulders preferably are generally in the shape of a portion of column having an axis perpendicular to said top surface and a cross section in the shape of a polygon.
