Liquid Container Relief Micro-Channel Gas Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for detergent and sanitizing liquid products with bleaching agents are complex and costly due to the relief systems required to manage gas generated by chemical reactions.
Innovation Solution
A container design featuring a bottle with a neck and a closing cap that includes a relief micro-channel connecting the product chamber to an outer chamber, allowing gas to escape while preventing liquid from leaking out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a relief system with membrane and outlet hole is used to discharge gas, then gas can flow out to prevent container deformation, but the closing cap structure becomes more complex and costly
Solution Approach 1:
The invention extracts the relief function from the closing cap by providing a separate relief system integrated into the bottle structure. The relief channel is obtained directly on the bottle wall, separating the gas discharge function from the closing cap, thereby simplifying the closing cap structure while maintaining reliable gas discharge capability.
Solution Approach 2:
The relief system is segmented into distinct functional components: the relief channel in the bottle wall for gas passage, and the closing cap for sealing. This segmentation allows each component to be optimized independently - the bottle handles gas relief while the closing cap focuses on sealing, reducing overall system complexity.
2Object-generated harmful factors
If a relief system with membrane is used to discharge gas, then gas can escape from the container, but the manufacturing cost and process complexity increase
Solution Approach 1:
The invention removes the membrane component from the relief system and integrates the relief channel directly into the bottle molding process. This extraction of the membrane requirement simplifies manufacturing while still effectively managing gas pressure buildup through the integrated relief channel.
Solution Approach 2:
The relief channel is merged with the bottle structure during molding, combining the bottle and relief system into a single integrated component. This merging eliminates separate membrane installations and reduces manufacturing steps, making production simpler and more cost-effective.

Function Achieved in This Case
The container is simpler and more cost-effective to manufacture, effectively managing gas release without compromising the integrity of the liquid product, thus preventing container deformation.
Implementation Method 1
a relief micro-channel, which is configured to allow the gas generated by the liquid product contained in the chamber to flow out of the chamber

AI summary
A container for liquid products has a bottle (2) provided with a neck (3), and a closing cap (6) provided with an outer cup (8), which is screwed onto the neck (3) and with an inner sleeve (14), which extends inside the neck (3), has a first coupling portion (15) coupled, in a fluid-tight manner, to a second coupling portion (16) obtained on an inner surface (11) of the neck (3) and defines, together with the bottle (2), a chamber (18) to contain a liquid product; at least one relief micro-channel (23; 24; 26) being obtained on at least one of the two coupling portions (15, 16) to allow a gas generated by the liquid product to flow out of the first chamber (18) and to at least limit, in particular prevent, the outflow of the liquid product itself from the first chamber (18).
