Bottom-Dial Cosmetic Package for Clean Ribbon Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic dispensers for semi-solid products, particularly stick products, face challenges in evenly spreading the product on the skin and often result in messiness due to top-dialed designs, necessitating a more efficient and cleaner application method.
Innovation Solution
A cosmetic package that dispenses semi-solid products in a ribbon form using a bottom-dialed dispenser, featuring a dispensing assembly with an outer container, inner container, screw rod assembly, piston, and dialer, which allows for controlled dispensing through discharge slits and cutters, ensuring smooth application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a top-dialed dispenser is used, then the structure is simple, but the application becomes messy and inconvenient
Solution Approach 1:
The patent inverts the traditional top-dialed dispenser design by placing the dialer at the bottom of the container. This inversion allows the user to operate the dispenser from the bottom, enabling cleaner and more controlled application of the cosmetic product while maintaining structural simplicity
2Ease of operation
If a stick product is dispensed directly, then the structure is simple, but the product cannot be spread evenly on the skin
Solution Approach 1:
The patent segments the dispensing system into multiple components: an inner container holding the stick product, an outer container with a dispensing surface, and a cutter mechanism. This segmentation allows the product to be dispensed in a controlled ribbon form through the discharge slits, enabling even spreading on the skin while maintaining reasonable structural complexity
3Ease of operation
If a ribbon form dispensing is implemented, then the application is smooth and even, but the device complexity increases
Solution Approach 1:
The patent merges the cutter function and discharge slit function into a single integrated component on the dispensing surface. This combination allows the product to be extruded and cut simultaneously in one operation, achieving smooth ribbon-form dispensing while minimizing the increase in device complexity
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 package provides a user-friendly, cost-effective solution for dispensing semi-solid products in a ribbon form, facilitating even distribution and reducing messiness, thereby enhancing the application experience.
Implementation Method 1
When the dialer is rotated, the inner and outer containers remain stationary, but the screw rod assembly rotates with the dialer, causing the piston to move upward and push the cosmetic product toward the dispensing surface
Implementation Method 2
The dialer is non-rotatably engaged to a lower end of the screw rod assembly, and rotatably engaged to a lower end portion of the inner container

AI summary
A cosmetic package for storing and dispensing a semi-solid product. The cosmetic package includes a dispensing assembly and a cap. The dispensing assembly comprises an outer container, an inner container, a screw rod assembly, a piston, and a dialer. The outer container includes discharge slits on its top wall for dispensing the product. The inner container, housed within the outer container, stores the semi-solid product. The screw rod assembly and piston are housed within the inner container to move the product upward when the dialer is rotated. The dialer is engaged to lower ends of the screw rod assembly and the inner container. An integrally formed cutter is located on a lower surface of top of the outer container, adjacent each of the discharge slits, that allows the product to be dispensed in a particular form through the discharge slits.
