Abstract

A medium includes a base layer and a separation layer. First to fifth regions are defined in the medium along a first direction in this order. Portions of the base layer which are in contact with the separation layer are stickable in at least a part of the first region and the fifth region and are not stickable in the second region and the fourth region. A length, in a second direction, of a second-side end portion of the fifth region in the first direction is less than a length, in the second direction, of a first-side end portion of the third region in the first direction. A length, in the second direction, of a first-side end portion of the fifth region in the first direction is less than the length, in the second direction, of the second-side end portion of the fifth region in the first direction.

First claim

What is claimed is:

1. A medium, comprising a base layer, an adhesive layer, a non-adhesive layer, and a separation layer stacked on each other in a stacking direction,
wherein a plurality of regions are defined in the medium along a first direction orthogonal to the stacking direction,
wherein the plurality of regions comprise:
a first region in which the base layer, the adhesive layer and the separation layer are stacked in order from one side of the medium toward the other side of the medium in the stacking direction and in which a portion of the base layer is stickable with respect to the separation layer in at least a part of the first region in a second direction orthogonal to each of the stacking direction and the first direction;
a second region located on a first side of the first region in the first direction and in which the base layer, the adhesive layer, the non-adhesive layer and the separation layer are stacked in order from the one side toward the other side of the medium in the stacking direction, the first side being opposite to a second side in the first direction, a printing background layer being provided in the second region, a portion of the base layer, which is located in the second region, being non-stickable with respect to the separation layer;
a third region located on the first side of the second region in the first direction and in which the base layer, the adhesive layer and the separation layer are stacked in order from one side of the medium toward the other side of the medium in the stacking direction;
a fourth region located on the first side of the third region in the first direction and in which the base layer, the adhesive layer, the non-adhesive layer and the separation layer are stacked in order from the one side toward the other side of the medium in the stacking direction, a portion of the base layer, which is located in the fourth region, being non-stickable with respect to the separation layer; and
a fifth region located on the first side of the fourth region in the first direction and in which the base layer, the adhesive layer and the separation layer are stacked in order from one side of the medium toward the other side of the medium in the stacking direction, a portion of the base layer, which is located in the fifth region, being stickable with respect to the separation layer,

wherein a length, in the second direction, of a second-side end portion of the fifth region in the first direction is less than a length, in the second direction, of a first-side end portion of the third region in the first direction, and
wherein a length, in the second direction, of a first-side end portion of the fifth region in the first direction is less than the length, in the second direction, of the second-side end portion of the fifth region in the first direction.

2. The medium according to claim 1 ,
wherein a first mark is provided in the first region, and
wherein a second mark is provided in the third region, and the second mark is aligned to the first mark in the first direction and is different from the first mark in length in the second direction.

3. The medium according to claim 2 , wherein in a case where a radius of a wrapped member around which the medium is to be wrapped is defined as r, a distance between the first mark and the second mark in the first direction is defined as L 1 , half a difference between a length of the first mark in the second direction and a length of the second mark in the second direction is defined as A, and half a deviation between the length, in the second direction, of the first-side end portion of the third region in the first direction and the length, in the second direction, of the second-side end portion of the fifth region in the first direction is defined as B, B satisfies a following expression: B>(A/L 1 )×2πr.

4. The medium according to claim 3 , wherein in a case where a length of the fifth region in the first direction is defined as L 2 , and half a deviation between the length, in the second direction, of the second-side end portion of the fifth region in the first direction and the length, in the second direction, of the first-side end portion of the fifth region in the first direction is defined as C, C satisfies a following expression: C>(A/L 1 )×L 2 .

5. The medium according to claim 1 , wherein a length of the first region in the second direction is less than a length of each of the second region and the third region in the second direction.

6. The medium according to claim 1 ,
wherein a length of the first region in the second direction is less than a length of each of the second region and the third region in the second direction, and
wherein a second mark is provided in the third region, and the second mark is aligned in the first direction to an edge portion of the first region in the second direction.

7. The medium according to claim 6 , wherein in a case where a radius of a wrapped member around which the medium is to be wrapped is defined as r, a distance between the edge portion of the first region in the second direction and the second mark in the first direction is defined as L 1 ′, half a length of the second mark in the second direction is defined as A′, and half a deviation between the length, in the second direction, of the first-side end portion of the third region in the first direction and the length, in the second direction, of the second-side end portion of the fifth region in the first direction is defined as B, B satisfies a following expression: B>(A′/L 1 ′)×2πr.

8. The medium according to claim 7 , wherein in a case where a length of the fifth region in the first direction is defined as L 2 , and half a deviation between the length, in the second direction, of the second-side end portion of the fifth region in the first direction and the length, in the second direction, of the first-side end portion of the fifth region in the first direction is defined as C, C satisfies a following expression: C>(A′/L 1 ′)×L 2 .

9. The medium according to claim 1 , further comprising a breakable portion extending in the second direction and formed in a portion of the base layer in the second region at a position near a boundary between the second region and the first region.
