Integrated Cap Assembly Opening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cap assemblies require separate processes for attaching the cap and inner stopper to a bottle, placing a technical burden on food manufacturers and complicating the manufacturing process, while also making it difficult for elderly individuals to open the bottle due to the need for multiple operations.
Innovation Solution
A cap assembly design where the inner stopper and cap are integrated, allowing the cap to be attached to the bottle with a screw thread system that includes a receiving section and protrusion to open the stopper by rotating the cap, eliminating the need for separate attachment processes and simplifying the opening mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cap and inner stopper are attached in separate processes, then the attaching position can be controlled with high precision, but the manufacturing complexity and burden on food manufacturers increases
Solution Approach 1:
The cap and inner stopper are integrated into a single component where the cap includes an integrated stopper portion that forms a unified structure. This merging eliminates the need for separate attachment processes while maintaining functional integrity through the screw thread connection between the cap body and stopper portion.
2Manufacturing precision
If the cap and inner stopper are attached in separate processes, then the attaching position can be controlled with high precision, but the facilities burden on food manufacturers increases
Solution Approach 1:
By combining the cap and inner stopper into a single integrated component, the invention eliminates the need for separate capping machinery and attachment facilities. The integrated structure can be attached to the bottle in a single operation, significantly reducing facilities requirements while maintaining precise positioning through the integrated screw thread design.
3Reliability
If multiple operations are required to open the bottle (remove cap, then open inner stopper), then the sealing function is maintained, but the usability for elderly persons deteriorates
Solution Approach 1:
The cap and inner stopper are merged into a single operational unit where rotating the cap simultaneously opens both the cap and the inner stopper. The integrated structure ensures that when the cap is rotated to open, the stopper portion is also opened, maintaining the sealing function while requiring only a single operation for the user.
Solution Approach 2:
The cap structure is designed to perform multiple functions: it serves as both the external cap and the inner stopper mechanism. The cap body includes an integrated stopper portion that can open the bottle closure, making the cap a multi-functional component that combines sealing and opening functions.
4Ease of operation
If a single integrated cap assembly is used, then the usability is improved by opening the stopper with cap operation, but the control of attaching position becomes more difficult
Solution Approach 1:
The cap and inner stopper are pre-integrated into a unified structure during manufacturing, with the stopper portion already positioned and configured within the cap body. This preliminary integration ensures that when the cap is attached to the bottle, the stopper is automatically positioned correctly without requiring separate precision control during the attachment process.
Solution Approach 2:
The integrated cap assembly is divided into functional segments (cap body, stopper portion, screw thread sections) that are designed to work together. The segmentation allows each part to be optimized for its function while maintaining precise relative positioning through the integrated screw thread connection mechanism.

AI summary
The present invention is related to a cap assembly which is put over a mouth of a bottle and a method for capping of capping the cap assembly to a bottle, and includes a function that makes it possible to open an inner stopper only by operating a cap when removing the cap initially, and makes attaching thereof to the bottle easy. There are included an inner stopper 40 and a cap 50, which respectively include a male screw thread 411c and a female screw thread 541, and the inner stopper 40 and the cap 50 while a state in which they are assembled is maintained are capped to a bottle 60, and when the cap 50 is removed initially, the cap 50 is firstly rotated in a direction of closing to have a junction section 52 broken, and then the cap 50 is rotated in a direction of opening so that the lid body 42 of the inner stopper 40 is removed together with cap 50, thereby causing the inner stopper 40 also to be in a state of being opened.
