Pressurized Discharge Valve Locking to Prevent Concentrate Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discharge devices allow for the premature removal of the discharge member before the concentrate is fully discharged, leading to potential leakage of the concentrate.
Innovation Solution
A discharge device with a double pressurized container system, where the concentrate and pressurizing agent are separately stored, and a discharge member with a valve mechanism that ensures the concentrate is fully discharged before the member can be removed, utilizing engaging projections and a maintaining mechanism to prevent unintentional removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the discharge member is simply screwed to the container, then the discharge member can be easily removed and recycled, but the concentrate may leak if the cap is removed before discharge is complete
Solution Approach 1:
The patent applies preliminary action by providing a maintaining mechanism that keeps the discharge member attached to the container until the discharge is complete. The engaging projection and groove structure ensures the discharge member cannot be accidentally removed before the concentrate is fully discharged, preventing leakage while still allowing easy removal after use for recycling.
Solution Approach 2:
The patent uses an intermediary mechanism (the maintaining mechanism with engaging projection and groove) that mediates between the discharge member and container. This intermediary structure ensures secure attachment during discharge while allowing controlled removal afterward, resolving the contradiction between easy removal and leakage prevention.
2Reliability
If the discharge member is securely fixed to prevent removal, then concentrate leakage is prevented, but the discharge member cannot be easily removed for recycling
Solution Approach 1:
The patent applies dynamics by creating a system that is dynamically secure during discharge (preventing accidental removal) but dynamically removable when needed (after complete discharge). The maintaining mechanism provides secure attachment during use while allowing intentional removal for recycling, resolving the contradiction between secure fixation and easy removal.
3Reliability
If a maintaining mechanism is added to prevent premature removal, then concentrate leakage is suppressed, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the discharge member into distinct functional components: the discharge valve portion and the maintaining mechanism with engaging projection. This segmentation allows the maintaining mechanism to be a simple, dedicated structure that prevents leakage without adding excessive overall complexity to the device.
Solution Approach 2:
The patent uses a simple geometric copying approach where the engaging projection on the discharge member fits into a corresponding groove on the container. This straightforward geometric relationship creates an effective maintaining mechanism with minimal structural complexity, resolving the contradiction between leakage prevention and device simplicity.

AI summary
To provide a discharge device which can suppress a leakage of a concentrate due to the removal of a valve. A discharge device is provided with a pressurized product 11a filling and sealing the concentrate C and the pressurizing agent P inside the container 10, and a discharge member 12 discharging the concentrate C by breaking through the pressurized product 11a. The discharge member 12 is provided with a valve 21 which becomes a discharge passage of the concentrate C, and a cap 20 which covers the valve 21 and is detachably mounted to the pressurized product 11a. It is provided with a suppressing means (a maintaining mechanism K, a movable lid 81, 91, pressing to the bottom 513d of the recessed part 513b of the projecting part 520a, a part releasing mechanism Re, a ratchet mechanism Ra, a thin part 15f and a plurality of coupling parts 15g) for suppressing the leakage of the concentrate C caused by removing the valve 21.
