Abstract
The present invention provides a cover tape comprising a tapelike base material 1, adhesive parts 2 formed on one side of the base material 1 at both edges along the longitudinal direction thereof, and a nonadhesive resin part 3 formed between the adhesive parts 2 and having substantially the same thickness as that of the adhesive parts 2. This cover tape is used to collectively pack chips and other small items while keeping them separate from each other to thereby permit the storage, transportation and automatic takeout thereof, which cover tape can be rendered very long. Further, the present invention provides a coating applicator suitable for use in the production of the above cover tape.
Claims22
A cover tape to be adhered to a surface of a carrier tape having a tape shape and having accommodation parts for accommodating chips and other small items formed discontinuously along the longitudinal direction of the carrier tape to thereby seal the accommodation parts, the cover tape comprising:
- a base material having edges;
- adhesive parts formed on one side of the base material adjacent both edges of the base material and extending along a longitudinal direction of the base material, wherein the adhesive parts are configured to oppose none of the accommodation parts;
- and
- a nonadhesive resin part formed on the one side of the base material between the adhesive parts and having substantially the same thickness as the adhesive parts, wherein the nonadhesive resin part is configured to oppose the accommodation parts.
A cover tape for a carrier assembly for the packing, storage, transportation and automatic takeout of a plurality of parts while keeping the parts unsoiled and separate from each other, the carrier assembly including a carrier tape having a plurality of recesses or through-holes for retaining the parts separate from each other, wherein the carrier tape and the cover tape cooperate to retain the parts therebetween, said cover tape comprising:
- a) a base material having edges;
- b) a pair of substantially parallel spaced apart adhesive layers formed on one surface of said base material and extending along the longitudinal axis of said one surface of said base material at both edges of said base material, said adhesive layers adapted to contact a pair of receiving surfaces extending along the longitudinal axis of the carrier tape when said cover tape is placed over the carrier tape and wherein neither of said adhesive layers is disposed above the parts when said cover tape is placed over the carrier tape;
- and
- c) a nonadhesive layer formed on said one surface of said base material, said nonadhesive layer located in a space formed between said spaced apart adhesive layers, and wherein said nonadhesive layer is disposed over the parts when said cover tape is placed over the carrier tape,
- wherein said nonadhesive layer has substantially the same thickness as that of said adhesive layers and prevents the parts from contacting said adhesive layers.
A carrier assembly for the packing, storage, transportation and automatic takeout of a plurality of parts while keeping the parts unsoiled and separate from each other, said carrier assembly including a carrier tape having a plurality of recesses or through-holes for retaining the parts separate from each other, wherein the carrier tape and the cover tape cooperate to retain the parts therebetween, said carrier assembly comprising:
- a) a carrier tape, said carrier tape including a pair of substantially parallel spaced apart receiving surfaces extending longitudinally along both edges of said carrier tape for receiving a cover tape, said carrier tape further including a means for retaining the parts separate and apart from each other on said carrier tape;
- and
- b) a cover tape, said cover tape being adhered with an adhesive to said cover tape receiving surfaces of said carrier tape, said cover tape and said carrier tape cooperating to retain the parts on said carrier tape without exposing the parts to said adhesive, said cover tape further including:
- i) a base material having edges;
- ii) a pair of substantially parallel spaced apart adhesive layers formed on one surface of said base material and extending along the longitudinal axis of said base material at both edges of said base material, said adhesive layers adapted to contact said pair of cover tape receiving surfaces of said carrier tape when said cover tape is placed over said carrier tape and wherein neither of said adhesive layers is disposed above the parts when said cover tape is placed over said carrier tape;
- and
- iii) a nonadhesive layer formed on said base material, said nonadhesive layer located in a space formed between said spaced apart adhesive layers, wherein said nonadhesive layer is disposed over the parts when said cover tape is placed over said carrier tape,
- wherein said nonadhesive layer has substantially the same thickness as that of said adhesive layers and prevents the parts from contacting said adhesive layers.
