Grooved Block Residual Quantity Reducer for Aerosol Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol container remaining-amount reduction members fail to prevent closed spaces generated by pressurized fluid, leading to content remaining inside, and their ejection stability and efficiency are compromised due to increased resistance and varying bag conditions.
Innovation Solution
A remaining-amount reduction member with a guiding part featuring grooved blocks connected in the longitudinal direction, each with a guiding groove oriented in 180° opposite directions, forming a continuous guiding space to ensure content flow to the inflow port, reducing closed space generation and stabilizing ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a dip tube is inserted as a remaining-amount reduction member, then the final remaining amount of content is reduced, but closed spaces are generated by pressurized fluid causing content to remain inside the dip tube
Solution Approach 1:
The guiding part is divided into multiple grooved blocks (first, second, third grooved blocks) connected in the longitudinal direction. Each block has guiding grooves that create segmented flow paths, preventing closed space formation while maintaining continuous content guidance from the inflow port to the ejection tip.
Solution Approach 2:
Guiding grooves are formed on the outer periphery of the grooved blocks, utilizing the radial dimension around the longitudinal axis. The grooves extend in the longitudinal direction while opening radially outward, creating a three-dimensional guiding structure that prevents pressurized fluid from forming closed spaces.
2Productivity
If existing remaining-amount reduction members are used, then some content is ejected, but ejection stability deteriorates due to increased resistance and varying bag conditions
Solution Approach 1:
Different grooved blocks have guiding grooves oriented in different directions (first block: upward, second block: downward, third block: upward). This local variation in groove orientation creates alternating flow paths that adapt to varying bag conditions and maintain stable ejection throughout the content depletion process.
Solution Approach 2:
The guiding grooves in adjacent grooved blocks are connected to form continuous guiding spaces that extend from the inflow port to the ejection tip. This continuity ensures uninterrupted content flow and stable ejection performance throughout the entire usage period.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces the final remaining amount of content, stabilizes ejection per unit time, and ensures smooth ejection without increasing resistance, even under varying bag conditions and material viscosities.
Implementation Method 1
the guiding grooves form guiding space continuing in the longitudinal direction... allows a flow of the content in a longitudinal direction
Implementation Method 2
fill the space between the interior bag and the exterior can with pressurized fluid to press the flexible interior bag and eject the content

AI summary
An object of the present invention is to provide a remaining-amount reduction member capable of preventing the generation of space whose periphery is closed by pressurized fluid, reducing a final remaining amount of a content to be ejected, stabilizing an ejection amount of the content per unit time, and smoothly ejecting the content to the end. Provided is a remaining-amount reduction member 110 that is attached inside a flexible interior bag 102 arranged inside an aerosol container 100 and is used to reduce a final remaining amount of a content F to be ejected, the remaining-amount reduction member including: an attachment part 120 attached such that the content F is capable of flowing in an inflow port 103 of the interior bag 102; and a guiding part 130 having a plurality of grooved blocks 132, each of which has a guiding groove 131 in a longitudinal direction, connected in the longitudinal direction.
