Cosmetic Jar Collar with Manipulation Surface for Powder Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic jar containers with loose powder products face challenges in evenly distributing the product onto applicators due to the messiness of loose powder, leading to uneven application and waste.
Innovation Solution
A cosmetic jar design featuring a collar with a manipulation surface extending into the neck, allowing users to scrape or rub the applicator to remove excess product, thereby achieving a desired distribution without external surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user rubs the applicator against the inside of the neck to remove excess product, then the applicator can be cleaned, but the product distribution on the applicator becomes uneven
Solution Approach 1:
The collar is segmented into distinct functional zones: a first portion with a first surface for initial product contact and a second portion with a second surface for final manipulation. This segmentation allows different surfaces to perform different functions - the first surface provides a larger area for product pickup while the second surface provides a controlled area for even distribution, resolving the contradiction between ease of cleaning and uniformity of application.
Solution Approach 2:
Different portions of the collar are given different local qualities - the first surface has a first configuration optimized for product contact and the second surface has a second configuration optimized for even distribution. This local differentiation allows each zone to be optimized for its specific function, enabling both effective cleaning and uniform product distribution simultaneously.
2Quantity of substance
If loose powder is used in a cosmetic jar, then the product can be stored, but it becomes messy and difficult to work with
Solution Approach 1:
The collar acts as an intermediary structure between the loose powder reservoir and the applicator. It provides a controlled interface where the applicator can pick up product in a manageable way, mediating between the messy nature of loose powder storage and the need for controlled application. The collar's surfaces provide a structured interaction point that reduces the messiness of working with loose powder.
3Ease of operation
If the collar manipulation surface extends further into the reservoir, then the applicator can be manipulated more effectively, but the reservoir space is reduced
Solution Approach 1:
The collar extends into the reservoir to a degree that provides sufficient manipulation surface area for effective applicator control, without excessively penetrating into the reservoir volume. The first and second surfaces are configured to provide adequate manipulation capability while maintaining optimal reservoir capacity, applying partial action that is just sufficient for the intended function.

AI summary
A cosmetic jar container configured with a collar insert to help distribute loose powder product on an applicator. An illustrative cosmetic jar includes a cap, ajar having a reservoir and a neck, and a collar secured to the neck of the jar. The collar includes a manipulation surface inside the neck for use in distributing a powder product on an applicator and/or removing excess product from the applicator.
