Abstract
An ink cartridge includes a casing and a seal member. The casing includes an ink storage section storing ink, an air communication hole that is a through hole to cause the ink storage section to communicate with air, and an air communication passage that is a groove connected to the air communication hole. The seal member covers an entire area of an opening of the air communication hole and an entire area of the air communication passage. A recess different from the air communication passage is formed in an area of the casing covered with the seal member. Part of an opening of the recess is exposed from the seal member.
Claims20
An ink cartridge comprising:
- a casing including an ink storage section that operates to store ink, an air communication hole that is a through hole that operates to cause the ink storage section to communicate with air, and an air communication passage that is a groove connected to the air communication hole;
- and
- a seal member that operates to be disposed on an external side or surface of the casing and to cover an entire area of an opening of the air communication hole and an entire area of or a part of the air communication passage,
- wherein a recess different from the air communication passage is formed in an area of the casing covered with the seal member, and
- wherein a part of an opening of the recess is exposed from the seal member such that a space extending between the seal member and the recess is accessible via the opening so that the seal member operates to be peeled off of the casing using a portion of the seal member extending over and partially covering the recess.
An ink cartridge comprising:
- a casing including an ink storage section that operates to store ink, an air communication hole that is a through hole that operates to cause the ink storage section to communicate with air, and an air communication passage that is a groove connected to the air communication hole;
- and
- a seal member that operates to be disposed on an external side or surface of the casing and to cover an entire area of an opening of the air communication hole and an entire area of or a part of the air communication passage,
- wherein a recess different from the air communication passage is formed in an area of the casing covered with the seal member, and
- wherein an entire area of an opening of the recess is covered with the seal member, and the seal member has a cut in an area disposed over and covering the recess such that the cut operates to permit access to or interaction with the recess and a portion of the seal member disposed over the recess so that the seal member operates to be peeled off of the casing using the portion of the seal member.
A method for remanufacturing an ink cartridge having a casing including an ink storage section that operates to store ink, an air communication hole that is a through hole that operates to cause the ink storage section to communicate with air, and an air communication passage that is a groove connected to the air communication hole, and a seal member that operates to be disposed on an external side or surface of the casing and to cover an entire area of an opening of the air communication hole and a part of or an entire area of the air communication passage, wherein a recess different from the air communication passage is formed in an area of the casing covered with the seal member, and a part of an opening of the recess is exposed from the seal member such that a space extending between the seal member and the recess is accessible via the opening so that the seal member operates to be peeled off of the casing using a portion of the seal member extending over and partially covering the recess, the method comprising:
- peeling off the seal member with the portion of the seal member extending over and partially covering the recess as a starting point for the peeling.
