Abstract
A wrapped package carries a transparent overwrap material and a tear tape attached to the overwrap material for effecting tearing of the overwrap material. The tear tape has a layer of adhesive on one side of the tape substrate for adhesion to the overwrap material and a layer of ink arranged to provide visible markings for the tear tape. The ink is applied on the side of the adhesive which is remote from the tape so that when the tear tape is attached to the overwrap material by the adhesive, the second surface of the adhesive and the layer of ink thereon are in contact with the overwrap material and the markings are visible through the transparent overwrap material without viewing through the adhesive and without viewing through the tape.
Claims6
In a wrapped package comprising:
- a package;
- a transparent overwrap material engaged around the package;
- and a tear tape attached to the overwrap material for effecting tearing of the overwrap material, the tear tape comprising:
- a tape substrate having sufficient strength to effect tearing of the overwrap material when pulled;
- a layer of adhesive on one side of the tape substrate for adhesion to the overwrap material, the layer of adhesive having a first side attached to the tape substrate and a second side remote from the tape substrate;
- and a layer of ink arranged to provide visible markings for the tear tape;
- the tear tape being adhesively attached to the overwrap material by the adhesive;
- the improvement in which:
- the ink to provide visible markings for the tape lies on said second side of the adhesive which is remote from the tape;
- the tear tape is attached to the overwrap material by the adhesive such that the second surface of the adhesive and the layer of ink thereon are in contact with the overwrap material and such that the layer of ink in contact with the overwrap material is visible through the transparent overwrap material without viewing through the adhesive and without viewing through the tape.
In a method for wrapping and unwrapping a package comprising:
- providing a package to be wrapped;
- providing a transparent overwrap material for engagement around the package;
- forming a tear tape for attachment to the overwrap material for effecting tearing of the overwrap material by:
- providing a tape substrate having sufficient strength to effect tearing of the overwrap material when pulled;
- applying a layer of adhesive on one side of the tape substrate for adhesion to the overwrap material, the layer of adhesive having a first side attached to the tape substrate and a second side remote from the tape substrate;
- and applying a layer of ink to provide visible markings for the tear tape;
- attaching the tear tape to the overwrap material using the adhesive;
- wrapping the overwrap material with the tear tape attached thereto around the package;
- and pulling the tear tape to effect tearing of the overwrap material;
- the improvement in which:
- the ink to provide visible markings for the tape is applied, subsequent to the application of the adhesive to said one side of the tape, to said second side of the adhesive which is remote from the tape;
- the tear tape is attached to the overwrap material using the adhesive such that the second surface of the adhesive and the layer of ink are in contact with the overwrap material and such that the layer of ink in contact with the overwrap material is visible through the transparent overwrap material without viewing through the adhesive and without viewing through the tape.
