Cosmetic Application Device Tilting Lid Scraping Container Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers with rotary bearing sections struggle to efficiently scrape off cosmetics from the bottom and upper corners, leading to waste and cosmetic residue visible from the outside, due to limitations in tilting and rotating movements, which result in incomplete usage and potential splattering.
Innovation Solution
A cosmetic application device with a container design featuring a mouth/neck section with stepped sections and a lid body that tilts without changing its height-wise position, allowing the application tool to contact the inner walls of the container, including the bottom and shoulder sections, for effective scraping, and a support shaft with a sloped application section to reach all areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a rotary bearing section is provided to enable tilting and rotating movement of the lid body, then the cosmetic can be scraped off from the bottom section, but the structure becomes complicated and industrial productivity deteriorates
Solution Approach 1:
The rotary bearing section is extracted from the container body and relocated to the lid body. This allows the lid body to perform tilting and rotating movements independently to scrape cosmetic from the container, while simplifying the container body structure and improving industrial productivity.
Solution Approach 2:
A tilting/rotating support shaft is introduced as an intermediary mechanism between the lid body and the application section. This shaft enables the lid body to tilt and rotate relative to the container body, facilitating cosmetic scraping from the bottom and upper corners without complicating the overall structure.
2Loss of substance
If the lid body is tilted to scrape off cosmetic from the inner wall, then cosmetic usage is improved, but the lid body moves over the rotary bearing section and gains momentum causing cosmetic splatter
Solution Approach 1:
The application section is designed with a scraping surface that preliminarily contacts and adheres to the cosmetic on the inner wall before the lid body tilts. This preliminary action prevents cosmetic splatter by securing the cosmetic to the application section during the tilting movement.
Solution Approach 2:
The application section is preliminarily inserted into the container body to scrape and collect cosmetic from the bottom and upper corners before the lid body performs tilting movement. This ensures cosmetic is gathered and secured, preventing splatter during subsequent movements.
3Loss of substance
If the support shaft is tilted to reach the upper corner of the container body, then cosmetic can be scraped from the shoulder section, but the tilting is restricted by the positional relationship with the opening
Solution Approach 1:
The support shaft is designed to perform tilting movement in multiple dimensions, including lateral tilting and vertical tilting. This multi-dimensional tilting capability allows the application section to reach the upper corner and shoulder section of the container body without being restricted by the opening's positional relationship.
Solution Approach 2:
The support shaft is designed with dynamic tilting capability, allowing it to adjust its angle and position during the scraping operation. This dynamic adjustment enables the application section to reach difficult-to-access areas like the upper corner and shoulder section while maintaining ease of operation.
4Loss of substance
If the application section is inserted deeply to scrape cosmetic from the bottom, then cosmetic usage is improved, but the squeezing member restricts the ability to reach upper corners
Solution Approach 1:
The container body is segmented into distinct sections: the containing section for holding cosmetic and the mouth/neck section with a smaller lateral cross-sectional area. This segmentation allows the application section to be inserted deeply to scrape cosmetic from the bottom while the lid body can tilt and rotate to access upper corners and shoulder sections without restriction.

AI summary
This cosmetic application device (1) includes an application tool (2) and a container (3), the application tool (2) being insertable into and removable from the container (3) through an opening (33) of the container (3). When the application tool (2) is tilted in a state where the fixation between the lid body (23) of the application tool (2) and the mouth/neck section (32) of the container (3) has been released and the lower end section (23d) of the lid body (23) is located at a position within the height-wise length of the mouth/neck section (32), the front end of the application section (21) of the application tool (2) is made to contact an inner wall in the vicinity of the bottom section of the containing section (31) of the container (3).
