Problem
Conventional cosmetic package containers for paste-type materials are difficult to assemble, lack distinct appearance from other elongated-shaped products, and have high production costs due to complex designs and manufacturing requirements.
Innovation Solution
A three-piece assembly cosmetic package container with a spherical shape, comprising a cap unit, base unit, and central ring unit, all formed with a double-layer structure of different materials, allowing for simplified assembly, reduced production costs, and a novel, visually appealing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional elongated tubular containers are used for cosmetic materials, then the container can store paste-type cosmetic material, but the appearance lacks distinction from other cosmetic products and causes user confusion
Solution Approach 1:
The patent transforms the conventional elongated tubular container shape into a spherical shape. The container body is designed as a sphere with a diameter of 1-2 cm, providing a completely different visual appearance that is appealing to consumers and easily distinguishable from other cosmetic products in the elongated tubular form factor.
2Shape
If conventional elongated tubular containers with special curves are used to modify appearance, then aesthetic effects are improved, but the container still fails to create a distinct appearance from other cosmetic products
Solution Approach 1:
The patent adopts a simple spherical shape without complex curves or modifications. This geometric transformation provides a completely distinct appearance from conventional elongated containers while maintaining structural simplicity, avoiding the need for complicated design elements.
Solution Approach 2:
The spherical container is divided into three main segments: a cap unit, a container body, and a base unit with filling opening. This segmentation allows for simplified manufacturing and assembly while maintaining the overall spherical aesthetic that provides visual distinction.
3Ease of manufacture
If conventional containers require skilled techniques or special machinery for filling, then the filling process can be completed, but the manufacturing cost increases and production complexity increases
Solution Approach 1:
The container is designed with a separate base unit that includes a predefined filling opening, allowing the filling process to be performed independently before final assembly. The cap unit and base unit are designed to assemble through simple threading or snapping mechanisms, eliminating the need for complex assembly machinery or skilled manual assembly techniques.
Solution Approach 2:
The filling opening is predefined at the base unit before the filling process, and the container components are designed to be pre-assembled or pre-prepared for easy final assembly. This preliminary preparation simplifies the overall manufacturing process and reduces the need for complex equipment during the filling and assembly stages.
4Ease of manufacture
If conventional containers use complicated components for assembly, then the container can be assembled, but the assembly difficulty increases and production cost increases
Solution Approach 1:
The container is divided into three main segments (cap unit, container body, base unit) that can be manufactured separately using standard injection molding techniques and then assembled through simple mechanical connections. This segmentation reduces component complexity while maintaining assembly functionality.
Solution Approach 2:
The patent combines multiple functions into integrated components. For example, the base unit integrates the filling opening, support frame attachment points, and sealing functions into a single molded piece, reducing the number of separate components and simplifying the overall assembly process.

AI summary
The present invention is related to a cosmetic package container, in particular, to a three-piece assembly of a cosmetic package container in a hollow spherical shape, comprising a cap unit and a base unit respectively of a semi-spherical hollow shape assembled in a top-down manner together with as a central ring unit having a net structure and attached to an opening of the base unit. A paste of cosmetic material is filled into the container via a filling perforation at the bottom portion of the base unit. The outer surface of the central ring unit is provided with threads for parts of the container to be fastened with ease to form a complete assembly of the container. The cap and base units are of a double-layered structure formed of different materials such that the outer appearance of the container can be of various decorative designs and is practical to use.
