Abstract

A liquid storage container for storing a liquid has a label member attached to a surface thereof. A bonding face of the label member that is bonded to the surface includes a first area and a second area having a low bonding strength. The second area covers a liquid supply port. A score line is formed on the label member, and the score line extends along a boundary between the first area and the second area and is formed in the second area.

First claim

What is claimed is:

1. A liquid storage container for storing a liquid having a label member attached to a surface thereof,
wherein a bonding face of the label member that is bonded to the surface includes a first area and a second area having a bonding strength lower than a bonding strength of the first area when the first area and the second area are bonded to the surface,
wherein the second area of the label member covers a liquid supply port that opens through the surface and through which the liquid is supplied to an inside of the liquid storage container, and
wherein a score line is formed on the label member, and the score line extends along a boundary between the first area and the second area and is formed in the second area.

2. The liquid storage container according to claim 1 ,
wherein the score line extends at an angle of 5 degrees or less with respect to the boundary.

3. The liquid storage container according to claim 2 , further comprising a print element substrate via which the liquid is discharged.

4. The liquid storage container according to claim 1 ,
wherein an adhesive material having a relatively high bonding strength is applied to the first area, and an adhesive material having a relatively low bonding strength is applied to the second area.

5. The liquid storage container according to claim 4 ,
wherein the adhesive material having a relatively low bonding strength is applied to one part of the second area, and the adhesive material having a relatively high bonding strength is applied to the other part of the second area.

6. The liquid storage container according to claim 5 , further comprising a print element substrate via which the liquid is discharged.

7. The liquid storage container according to claim 4 , further comprising a print element substrate via which the liquid is discharged.

8. The liquid storage container according to claim 1 ,
wherein an adhesive material is applied to the first area, an application agent having no bonding strength is applied to one part of the second area, and the adhesive material is applied to the other part of the second area.

9. The liquid storage container according to claim 1 ,
wherein a groove extending from a recessed portion formed around the liquid supply port so as to meander around the recessed portion is formed on the surface of the liquid storage container, and the label member is attached to the surface so as to surround the groove other than an end portion of the groove.

10. The liquid storage container according to claim 9 ,
wherein the label member is attached to the surface such that a portion of the label member that is defined by the score line and whose bonding face includes the first area covers part of the groove.

11. The liquid storage container according to claim 1 ,
wherein the label member includes a pair of opposing side portions, a portion of the label member that is defined by the score line and whose bonding face includes the first area is adjacent to one of the side portions.

12. The liquid storage container according to claim 11 ,
wherein the label member is attached to the surface such that the other side portion protrudes from an edge portion of the surface.

13. The liquid storage container according to claim 12 ,
wherein the score line is formed in an L-shape such that a long side thereof extends at an angle of 5 degrees or less with respect to the other side portion.

14. The liquid storage container according to claim 11 ,
wherein the bonding face of the label member includes a third area that extends linearly along the other side portion and that has a bonding strength higher than the bonding strength of the second area.

15. The liquid storage container according to claim 11 ,
wherein the bonding face of the label member includes a pair of third areas that are formed at both ends of the other side portion and that each have a bonding strength higher than the bonding strength of the second area.

16. The liquid storage container according to claim 11 ,
wherein the bonding face of the label member includes plural third areas that extend along the other side portion and that each have a bonding strength higher than the bonding strength of the second area.

17. The liquid storage container according to claim 11 , further comprising a print element substrate via which the liquid is discharged.

18. The liquid storage container according to claim 1 ,
wherein information about the liquid storage container is described on a back face of the first area of the label member.

19. The liquid storage container according to claim 18 ,
wherein the information is about the liquid contained in the liquid storage container.

20. The liquid storage container according to claim 1 , further comprising a print element substrate via which the liquid is discharged.
