Pressurized Gas Bottle Cap for Residual Fluid Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bottles containing pressurized combustible fluids pose a risk of explosion during recycling due to residual fuel, and existing designs do not ensure complete emptying, leading to inefficiencies and safety hazards.
Innovation Solution
A bottle design featuring a cap with integrated pusher and coupling means that allows for safe venting and emptying of residual fluid, ensuring the valve is irreversibly opened for complete discharge, reducing the risk of explosion and optimizing production costs by integrating components for easier manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bottles containing pressurized combustible fluids are recycled using presses or high temperature furnaces, then recycling can be performed, but dangerous explosions may occur due to residual combustible fluid
Solution Approach 1:
The patent applies preliminary action by providing a venting cap that can be applied before recycling to remove residual combustible fluid from the container. The cap includes a pusher that irreversibly opens the delivery valve, allowing complete emptying of the container through the delivery line. This preliminary emptying action eliminates the explosion hazard that would otherwise exist during subsequent recycling operations in presses or furnaces.
Solution Approach 2:
The patent extracts the harmful residual combustible fluid from the container by providing a dedicated venting mechanism. The venting cap with its integrated pusher and coupling means enables complete removal of fluid through the delivery line, separating the fluid removal function from the container's normal dispensing function. This extraction of residual fluid eliminates the explosion risk during recycling.
2Ease of operation
If traditional valve closing mechanisms are used, then the valve can be opened and closed for dispensing, but complete emptying of the container cannot be ensured
Solution Approach 1:
The venting cap performs a preliminary action of irreversibly opening the valve to maximize fluid discharge. The pusher is configured to push the valve element to its fully open position, and the irreversible coupling ensures the valve remains open for complete emptying. This preliminary irreversible opening action ensures no residual fluid remains in the container.
Solution Approach 2:
The system enables self-service complete emptying by providing a simple venting cap that the user applies to the container outlet. The cap's integrated pusher automatically actuates the valve mechanism to fully open position, and the irreversible coupling mechanism ensures the valve stays open, allowing the container to empty itself completely without requiring additional disassembly or complex operations.

AI summary
Described is a bottle comprising: i) a container (2) of a pressurised fluid comprising a storage chamber (20) for the fluid, a delivery conduit (21) for the fluid, a valve (3) situated along the delivery conduit (21) and movable between a first position in which it prevents the discharge of pressurised fluid from the container (2) and a second position in which it permits the discharge of pressurised fluid from the container (2); ii) a cap (4) for covering the outlet (22) for the exit of the fluid from the container (2), the cap (4) being connected to the container (2) at least in a first configuration of the bottle (1) and comprising: -means (5) for venting and emptying the residual fluid present in the storage chamber (20) which in turn comprises a pusher (50) suitable for interacting with the valve (3); -a first portion (6) from which the pusher (50), extending along its preponderant axis (51) of extension, projects outward as far as its first end (52), in the first configuration the pusher (50) projecting from the first portion (6) toward the valve (3); -first coupling means (7) which in the first configuration are connected to the container (2), the first coupling means (7) extending at least in part along at least a part of an imaginary closed line which surrounds the axis (51) of the pusher (50).
