Bottle Set With Integrated Nozzle and Sealing Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle sets for ink ejection systems have a complex configuration with multiple parts, making it difficult to reduce the number of components while maintaining airtightness and preventing ink evaporation and degradation.
Innovation Solution
A bottle set design featuring a bottle with an integral nozzle and a lid member that includes a sealing portion, such as a plate-shaped abutting portion or a plug, to seal the outflow port, reducing the number of parts required and enhancing airtightness by elastic deformation or insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing member is interposed between the lid member and the discharge port, then the discharge port can be sealed, but the number of parts increases
Solution Approach 1:
The sealing member is integrated into the lid member as a unified structure. The lid member includes a sealing portion that directly contacts the discharge port, eliminating the need for a separate sealing member. This merging of the sealing function into the lid member reduces the total number of parts while maintaining effective sealing of the discharge port.
2Ease of operation
If the lid member is made detachable for easy removal, then ease of operation improves, but airtightness may be compromised
Solution Approach 1:
The lid member is pre-equipped with a threading structure and sealing portion that engage with the bottle's discharge port in a standardized manner. The threading structure allows for simple screw-on/screw-off operations, while the sealing portion is pre-positioned to ensure immediate sealing upon attachment, thus maintaining airtightness while enabling easy removal and reattachment.

AI summary
A bottle set includes a bottle and a lid member. The bottle has an ink container, a nozzle and a joint portion integrally formed with the nozzle and having a thread configured to engage the nozzle with the ink container. The lid member is attachable to and detachable from the bottle. An outflow port is formed in the nozzle. The outflow port is configured such that the ink in the ink container flows out from the outflow port. The lid member has a tubular barrel, a top plate that closes a barrel end of the tubular barrel, and a plug projecting from the top plate toward the nozzle. A distance from the barrel end of the tubular barrel to a distal end of the plug being shorter than a distance from a nozzle end of the nozzle to the joint portion.
