1. An ink cartridge comprising a main body, a cover member, and an insulating seal member, which are components for constituting the ink cartridge for an inkjet printer, whereinthe main body and the cover member are bonded to each other with an electrically-disbonding adhesive having a characteristic of causing a bond dissociation with a passage of an electric current so as to form an ink storing section,the main body has a first electrode being arranged at a portion where the main body is in contact with the electrically-disbonding adhesive for passing the electric current through the electrically-disbonding adhesive,the cover member has a second electrode being arranged at a portion where the cover member is in contact with the electrically-disbonding adhesive for passing the electric current through the electrically-disbonding adhesive,the seal member is arranged in the vicinity of a bonding portion where the main body and the cover member are bonded to each other so as to keep the cartridge liquidtight, and so as to prevent an ink stored in the storing section from being in contact with the first and the second electrodes.
2. The ink cartridge according to claim 1, whereinthe seal member is arranged so as to be in contact with the vicinity of the bonding portion at the wall surface of the main body constituting the storing section and the vicinity of the bonding portion on the wall surface of the cover member constituting the storing section.
3. The ink cartridge according to claim 1, whereinthe main body is a container including a bottom portion and a side wall portion, wherein a top portion is open,the cover member is made of an upper cover that covers the opening at the top portion of the main body and a rib that is fitted to the opening, and an edge of the upper cover is bonded to an upper edge of the side wall portion of the main body, andthe seal member is arranged between the rib of the cover member and the side wall portion of the main body.
4. The ink cartridge according to claim 3, wherein the first and the second electrodes have a U-shape for covering respectively the edge of the side wall portion and the edge of the upper cover.
5. The ink cartridge according to claim 1, whereinthe main body is a container having a polyhedron shape, and an opening is formed in its one plane,the cover member is arranged to cover the opening, and bonded to the main body around the opening, andthe seal member is arranged between a portion where the cover member is bonded to the main body and the opening.
6. The ink cartridge according to claim 5, whereinthe main body has a convex portion formed between a portion where the seal member is arranged and a portion where the cover member is bonded to the main body, wherein the convex portion has a height by which a gap for allowing the electrically-disbonding adhesive to apply between the main body and the cover member can be secured.
7. The ink cartridge according to claim 5, wherein the cover member is made of copper.
8. The ink cartridge according to claim 1, wherein the electrically-disbonding adhesive is an epoxy-based adhesive.
9. The ink cartridge according to claim 1, wherein the seal member is made of an elastic rubber.
10. The ink cartridge according to claim 1, wherein the seal member is made of fluororesin.
11. A recycling method of the ink cartridge according to claim 1, comprising the steps of:peeling the electrically-disbonding adhesive through the application of a voltage between the first electrode and the second electrode; andseparating the main body and the cover member.
12. The recycling method according to claim 11, wherein the voltage applied between the first electrode and the second electrode is an AC voltage. |
