Abstract

The disclosure discloses an adhesive tape cartridge including an adhesive tape roll. The adhesive tape roll winds an adhesive tape around a predetermined axis in a housing. The adhesive tape includes a base layer, and a first particle-containing adhesive layer. The first particle-containing adhesive layer is disposed on first side of the base layer in a thickness direction and comprises an adhesive to which particles having an average particle diameter of 10 μm or more are added. On condition that the first particle-containing adhesive layer is virtually divided into two equal parts as a first region on the first side in the thickness direction and an second region on an second side in the thickness direction, a volume proportion of the particles to the adhesive in the second region is larger than a volume proportion of the particles to the adhesive in the first region.

First claim

What is claimed is:

1. An adhesive tape cartridge comprising:
an adhesive tape roll that winds an adhesive tape around a predetermined axis in a housing,
said adhesive tape comprising:
a base layer; and
a first particle-containing adhesive layer that is disposed on a first side of said base layer in a thickness direction and comprises an adhesive to which particles having an average particle diameter of 10 μm or more are added,
wherein said first particle-containing adhesive layer is virtually divided into two equal sides as a first region on said first side in the thickness direction and a second region on a second side in the thickness direction, wherein the second side of the first particle-containing layer is nearer the base layer than the first side of the first particle-containing layer, wherein said first region comprises particles having an average particle diameter of 10 μm or more, a second region volume ratio being larger than a first region volume ratio, wherein the second region volume ratio is a ratio of a volume of the particles in the second region to a volume of the adhesive in the second region, and wherein the first region volume ratio is a ratio of a volume of the particles in the first region to a volume of the adhesive in the first region.

2. The adhesive tape cartridge according to claim 1 , wherein
in said first particle-containing adhesive layer, a concentration of said particles in the adhesive in said second region is higher than a concentration of said particles in the adhesive in said first region.

3. The adhesive tape cartridge according to claim 1 , wherein
in said first particle-containing adhesive layer, the second region volume ratio is more than 1.5 times as large as the first region volume ratio.

4. The adhesive tape cartridge according to claim 1 , wherein
in said first particle-containing adhesive layer, an average particle diameter of said particles in said second region is larger than an average particle diameter of said particles in said first region.

5. The adhesive tape cartridge according to claim 4 , wherein
in said first particle-containing adhesive layer, the average particle diameter of said particles in said second region is more than 1.5 times as large as the average particle diameter of said particles in said first region.

6. The adhesive tape cartridge according to claim 1 , wherein
said adhesive tape further comprises a colored layer that is disposed on said first side of said base layer in the thickness direction and on said second side of said first particle-containing adhesive layer in the thickness direction.

7. The adhesive tape cartridge according to claim 1 , wherein
said adhesive tape further comprises a colored layer that has a transmittance of 20% or more and is disposed on said second side of said base layer in the thickness direction.

8. The adhesive tape cartridge according to claim 1 , wherein
said adhesive tape further comprises:
an affixing adhesive layer disposed on said second side of said base layer in the thickness direction; and
a separation material layer disposed on said second side of said affixing adhesive layer in the thickness direction.

9. The adhesive tape cartridge according to claim 8 , further comprising in said housing,
a cover film roll that winds a cover film bonded to a surface on said first side of said first particle-containing adhesive layer of said adhesive tape in the thickness direction; and
an ink ribbon roll that winds an ink ribbon configured to transfer ink to said second side of said cover film in the thickness direction, the cover film being fed out from said cover film roll.

10. The adhesive tape cartridge according to claim 1 , wherein
said adhesive tape further comprises:
a second particle-containing adhesive layer that is disposed on said second side of said base layer in the thickness direction and comprises particles added thereto; and
a separation material layer that is disposed on said second side of said second particle-containing adhesive layer in the thickness direction, wherein
said second particle-containing adhesive layer is virtually divided into two equal sides as a third region on said first side of the second particle-containing layer in the thickness direction and a fourth region on said second side of the second particle-containing layer in the thickness direction, wherein the first side of the second particle-containing layer is nearer the base layer than the second side of the second particle-containing layer, a third region volume ratio being larger than a fourth region volume ratio, wherein the third region volume ratio is a ratio of a volume of the particles in the third region to a volume of the adhesive in the third region, and wherein the fourth region volume ratio is a ratio of a volume of the particles in the fourth region to a volume of the adhesive in the first region.

11. The adhesive tape cartridge according to claim 10 , wherein
a concentration of said particles in the adhesive in said third region is higher than a concentration of said particles in the adhesive in said fourth region.

12. The adhesive tape cartridge according to claim 10 , wherein
in said second particle-containing adhesive layer, an average particle diameter of said particles in said third region is larger than an average particle diameter of said particles in said fourth region.

13. The adhesive tape cartridge according to claim 1 , wherein
said adhesive tape further comprises a separation material layer disposed on said first side of said first particle-containing adhesive layer in the thickness direction.

14. The adhesive tape cartridge according to claim 13 , wherein
said adhesive tape further comprises an ink image receiving layer that has a transmittance of 20% or more, is disposed on said second side of said base layer in the thickness direction, and is configured to receive transfer of ink.

15. The adhesive tape cartridge according to claim 13 , further comprising in said housing an ink ribbon roll that winds an ink ribbon configured to transfer said ink to said adhesive tape.

16. The adhesive tape cartridge according to claim 1 , wherein
the first particle-containing adhesive layer or the second particle-containing adhesive layer has an adhesive force of 3 [N]/10 [mm] or more.

17. The adhesive tape cartridge according to claim 1 , wherein
said particles added to said first particle-containing adhesive layer are pigment.

18. The adhesive tape cartridge according to claim 17 , wherein
said pigment is a glittering pigment.
