Drug-Containing Hygiene Implement With Sealed Drug Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drug-containing interdental brushes face challenges in production and management due to drug leakage during manufacturing, transportation, and storage, and pose hygiene concerns due to open drug supply apertures and internal contamination.
Innovation Solution
A drug-containing personal hygiene implement with a bottle body storing the drug and a personal hygiene component, featuring a passage for drug delivery to the hygiene body, where the drug can flow through upon opening, and a cap body to block and control the passage, ensuring sealed storage and easy application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drug supply aperture is provided in conventional drug-containing interdental brushes, then the drug can be supplied to the personal hygiene body, but the drug leaks during manufacturing, transportation, and storage
Solution Approach 1:
The patent separates the drug supply aperture function from the bottle structure by using a removable cap that covers the aperture. The aperture exists in the bottle but remains closed during storage and transport, and is only opened when the cap is removed for use. This extracts the harmful open aperture state while preserving the useful drug supply capability.
Solution Approach 2:
The bottle is manufactured and sealed with the aperture closed before the drug is filled. The cap is pre-installed to seal the aperture, preventing any potential leakage during manufacturing, transportation, and storage. The aperture is only opened when needed for drug supply to the personal hygiene body.
2Ease of operation
If a drug supply aperture is provided in conventional drug-containing interdental brushes, then the drug can be supplied to the personal hygiene body, but hygiene is compromised due to open communication between interior and exterior
Solution Approach 1:
The harmful open communication between the bottle interior and exterior is extracted by using a cap that seals the aperture. The aperture structure remains in the bottle for drug supply functionality, but the cap removes the harmful exposure to contaminants during storage and transport.
Solution Approach 2:
The cap acts as a flexible seal that covers the aperture, creating a barrier between the sterile interior environment and the external environment. This thin film-like closure maintains hygiene by preventing contamination while allowing easy removal for drug supply.
3Strength
If external force acts on the bottle during manufacturing or storage, then the bottle structure remains intact, but the drug is expelled through the supply aperture
Solution Approach 1:
The vulnerability of the aperture to external force is extracted by sealing it with a cap. The bottle structure itself remains strong and intact, but the cap provides an additional sealing layer that prevents drug expulsion through the aperture when external forces are applied during handling, transportation, or storage.
4Ease of operation
If the personal hygiene implement and drug bottle are integrated, then portability is improved, but production and product management become difficult
Solution Approach 1:
The integrated product is segmented into three main components: the bottle body containing the drug, the personal hygiene body (such as interdental brush), and the cap that seals the aperture. This segmentation allows each component to be manufactured separately using standard processes, then assembled together, simplifying production while maintaining the portable integrated form factor.

AI summary
To provide an economical and sanitary drug-containing personal hygiene implement that is easy to produce and manage, and has an excellent portability even when both personal hygiene implement and drug are used away from home.The drug-containing personal hygiene implement includes a bottle body in which a drug is stored, a personal hygiene body which has a shaft section and a distal-end personal hygiene section, protrudes to a distal-end side of the bottle body, and is used to implement care of a human body, and a passage provided on a distal-end section of the bottle body and guiding the stored drug to the personal hygiene body, the implement being characterized in that opening operation makes it possible for the drug to flow through the passage in the bottle body.
