Liquid applied seal for inkjet orifices
View Patent ↗A liquid is applied by a bounded-region applicator such as a needle applicator over nozzle holes and over at least a continuous region close to the nozzle holes. The liquid is then cured to a solid before significant flow of the liquid into the nozzle holes. The liquid is chosen to cure to a solid which is sufficiently compliant that it deforms and leaves the nozzle holes under moderate pressure from a human hand or finger without breaking. Depending upon the material in which the nozzles are formed and the size of the nozzle holes, the liquid may be uniquely designed to incorporate resilient moieties or segments to satisfy these factors.
1. A method of sealing the orifices of an inkjet ink container comprising:
applying a liquid by a bounded-region applicator having an internal conduit with an oblong opening, the oblong opening allowing the liquid to be applied in a controlled manner over said orifices and at least in a contiguous regions around each of said orifices to seal said orifices from leaking ink during normal storage and handling; and
curing said liquid to its cured state, said cured state be sufficiently compliant to permit said cured liquid to be removed from said orifices and said contiguous regions under moderate pressure from a human hand or finger.
2. The method of claim 1 in which said curing is before said liquid has flowed significantly into said nozzle holes.
3. The method as in claim 2 in which said bounded-region applicator comprises a needle with said internal conduit through which said liquid is applied.
4. The method of claim 1 in which said bounded-region applicator comprises a needle with said internal conduit through which said liquid is applied.
