Double-Ended Cosmetic Container for Complete Product Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic containers fail to extract all liquid cosmetic material, leading to wastefulness as the applicator wand cannot reach the bottom without bending or breaking, resulting in unused product being discarded.
Innovation Solution
A double-ended cosmetic container with interchangeable caps and inserts that allow the applicator wand to extend from either end, featuring wiper lips and funneling configurations to scrape and collect remaining material, ensuring nearly all product is used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the applicator wand is extended to reach the bottom of the container, then complete cosmetic material removal is achieved, but the brush or sponge material bends, breaks, or gets damaged
Solution Approach 1:
The container is divided into two separate chambers, each accessible from different ends. This segmentation allows the applicator to be used from both ends, enabling complete product extraction without requiring the applicator to reach the bottom of a single deep chamber, thus preventing damage while maximizing product usage.
Solution Approach 2:
The invention transitions from a single-ended linear extraction approach to a dual-ended approach, effectively adding a dimensional aspect to the product removal process. By making the container accessible from both ends, the applicator can extract product from either direction, eliminating the need to extend excessively deep into one chamber.
2Device complexity
If a single-ended container design is used, then the structure is simple, but cosmetic material cannot be completely removed
Solution Approach 1:
The container is segmented into two chambers with separate access points, allowing the applicator to extract cosmetic material from both ends. This segmentation enables near-complete product removal while maintaining relatively simple construction using basic components like chambers, caps, and wiper lips.
Solution Approach 2:
The container is designed with multi-functionality by enabling access from both ends. Each end can serve as an active extraction point, making the container universally accessible from either direction. This dual-function design maximizes product usage without requiring complex additional mechanisms.
3Reliability
If the applicator wand does not reach the bottom of the container, then the brush or sponge material remains intact, but cosmetic material at the bottom cannot be removed
Solution Approach 1:
By segmenting the container into two chambers accessible from different ends, the invention allows the applicator to extract product from shallower depths at each end while still achieving complete product removal. This maintains applicator integrity while improving extraction efficiency.
Solution Approach 2:
Instead of extending the applicator deeply into one chamber, the invention inverts the approach by providing access from both ends. The applicator can be inserted from either end to extract remaining product, effectively reversing the traditional single-direction extraction method and improving both durability and efficiency.

AI summary
A cosmetic apparatus includes a double-ended cosmetic container having a liquid cosmetic reservoir chamber therein. Interchangeable end caps are removably attached to generally opposite ends of the container. An applicator wand, attached to the first end cap, is insertable through the first end and a first wiper insert, and selectively moved to the generally opposite second end so as to be insertable through the second open end and second insert, which is configured to funnel cosmetic material into the second insert and onto the applicator so as to capture the remaining cosmetic material.
