Reusable Pouch Air Valve with Piercing Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing pouches with integrated air valves require secure bonding, leading to environmental burden and increased production costs when the pouch is discarded, and necessitate pre-formed apertures or specialized pouches for air valve installation, limiting usability and flexibility.
Innovation Solution
A pouch air valve system comprising a coupling duct and a piercing base, where the piercing base can pierce through the pouch to align with the duct, allowing the air valve to be installed without pre-existing apertures, enabling flexible placement and reuse on various pouches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air valve is securely bonded to the zipper bag to ensure airtight efficacy, then the airtight performance is improved, but the environmental burden increases and production cost rises when the pouch is discarded
Solution Approach 1:
The air valve system is divided into two separate components: a reusable air valve unit and a disposable piercing base. The piercing base is integrated with the pouch, while the air valve can be removed and reused on other pouches. This segmentation allows the airtight function to be maintained while reducing waste, as only the small piercing base is discarded rather than the entire air valve assembly.
2Ease of manufacture
If pre-formed apertures are created on the sealing pouch for air valve installation, then the air valve can be properly installed, but the usability and flexibility are reduced
Solution Approach 1:
The piercing base is pre-formed with a piercing head that can penetrate the pouch material. This preliminary preparation of the piercing base allows for easy installation on any pouch without requiring pre-formed apertures. The piercing action creates the necessary opening during the installation process itself, providing both ease of manufacture and flexibility in use.
3Adaptability or versatility
If a reusable air valve system is implemented without pre-formed apertures, then usability and flexibility are improved, but the installation mechanism becomes more complex
Solution Approach 1:
The piercing base integrates multiple functions into a single component: it provides the piercing head for creating the aperture, the mounting structure for attaching the air valve, and the sealing interface. This merging of functions simplifies the overall installation mechanism while maintaining reusability and flexibility, as the integrated design reduces the number of separate parts and assembly steps required.

AI summary
A pouch air valve used on a sealing pouch comprises a coupling duct and a piercing base. The coupling duct includes a duct, an air valve and a first suction plate. The piercing base has a piercing head and a second suction plate. The first suction plate surrounds and seals the duct to form coupling therewith. The piercing head has an airflow passage running through two sides thereof. The second suction plate surrounds and seals the piercing head to form coupling therewith. The piercing base is positioned at one side of the sealing pouch while the duct is directly aligned and coupled with the piercing head from another side of the sealing pouch so that the piercing head can pierce through the sealing pouch to allow the first and second suction plates to attract each other and anchor on the sealing pouch which serves as separation.
