Absorbent Article Packaging With Separate Odor Adsorbent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles fail to maintain their adsorbing capability over time, particularly after use, leading to odor issues during storage.
Innovation Solution
A package and container design that separates the absorbent from the absorbent article, allowing the absorbent to maintain its adsorbing capability post-use by containing it within a packaging or containing space, preventing degradation during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the absorbent is positioned between the topsheet and the absorbent core to exert moisture absorbing capability during use, then the adsorbing capability is utilized during use, but the adsorbing capability is gradually degraded after use and cannot be maintained
Solution Approach 1:
The absorbent is separated from the absorbent article into a distinct packaging component. This segmentation allows the absorbent to remain isolated during use (maintaining its adsorbing capability) while still being part of the overall product system. The absorbent is placed in a packaging space separate from the absorbent article, enabling it to function independently after use without degrading during the product's operational phase.
Solution Approach 2:
The absorbent is pre-positioned in the packaging space before use, ready to exert its adsorbing capability on the absorbent article after use. This preliminary positioning ensures that the absorbent is in the optimal state (unused, high adsorbing capability) when needed, and can immediately begin adsorbing substances from the used absorbent article without degradation.
2Object-generated harmful factors
If the absorbent is kept with the absorbent article after use, then the absorbent can adsorb substances, but odor and adverse impacts occur during the keeping process
Solution Approach 1:
The absorbent article is nested within the packaging that contains the absorbent. This nested structure allows the used absorbent article to be contained within the same packaging space as the absorbent, enabling the absorbent to adsorb odors and harmful substances from the used article while maintaining a compact, organized structure. The absorbent acts as a protective layer within the nested packaging system.
Solution Approach 2:
The absorbent serves as an intermediary substance between the used absorbent article and the external environment. It mediates by adsorbing harmful substances and odors from the used article, preventing them from spreading. The absorbent is positioned to interact with the used article through the packaging structure, acting as a buffer and filter.
3Device complexity
If the absorbent is integrated into the absorbent article, then the structure is simplified, but the adsorbing capability cannot be maintained after use
Solution Approach 1:
The packaging structure serves multiple functions: it contains the absorbent article during use, houses the absorbent for post-use treatment, and provides a sealed environment for odor control. This multi-functional packaging eliminates the need for separate structures for each function, maintaining simplicity while enabling the absorbent to exert its capability at different stages (before, during, and after use).
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
The absorbent effectively maintains its adsorbing capability on the used absorbent article, reducing odor and maintaining performance over time.

AI summary
To provide an absorbent article and the like capable of exerting an adsorbing capability after the absorbent article is used. A package (1) includes an absorbent article (10) having a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a packaging sheet (20) for individually packaging the absorbent article. The package includes an absorbent (50) that adsorbs at least one of an inorganic substance and an organic substance. The absorbent is separate from the absorbent article and is provided within a packaging space (WS) that contains the absorbent article in the package.
