Integrally Formed Shoulder Bush and Portion in Eco-Pump Cosmetic Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressurized cosmetic containers with complex structures increase manufacturing costs and economic burdens due to the separation issues between the shoulder portion and shoulder bush, leading to inefficient sealing and pumping effects.
Innovation Solution
An eco-pump type cosmetic container with a shoulder portion and shoulder bush integrally formed, featuring an elastic member made of silicone rubber with antibacterial properties, and a pressing portion that ensures complete sealing and easy operation by guiding the pressing portion along a guide surface, preventing separation and maximizing the pumping effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pressurized pump structure is used, then a predetermined amount of cosmetic can be supplied to the user, but the structure becomes very complicated and manufacturing costs increase
Solution Approach 1:
The pump mechanism is divided into distinct functional segments: the pressing portion (500) for user operation, the elastic member (400) for pressure generation and dosage control, and the shoulder portion (200) for structural support. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure simpler than conventional pumps.
Solution Approach 2:
The complex mechanical valve and piston mechanisms found in conventional pumps are extracted and replaced with a simplified elastic member system. The elastic member (400) alone provides both the pressure generation and the dosage control functions that traditionally required multiple separate components, thereby reducing structural complexity while maintaining reliability.
2Ease of manufacture
If separate shoulder bush and shoulder portion are used, then assembly is possible, but separation occurs leading to incomplete sealing and reduced pumping effect
Solution Approach 1:
The shoulder bush (300) and shoulder portion (200) are merged into a single integrally formed component. This eliminates the interface between these two parts, preventing separation and ensuring complete sealing between the shoulder assembly and the container (100), thereby maintaining reliable pumping action without compromising manufacturability.
Solution Approach 2:
The integrally formed shoulder portion shoulders bush assembly serves multiple functions simultaneously: it provides structural support, ensures sealing between components, guides the pressing portion movement, and maintains the pumping effect. This multi-functionality is achieved through a single component design that eliminates the need for separate parts while improving reliability.
3Device complexity
If the seat portion is not properly supported, then the structure is simpler, but the seat portion is difficult to open
Solution Approach 1:
The upper end of the shoulder bush (300) acts as an intermediary support element between the pressing portion (500) and the seat portion (470). When the user presses the pressing portion, the force is transmitted through the shoulder bush to the seat portion, providing mechanical advantage that makes it easy to open the seat without requiring complex support structures.
4Strength
If metallic materials are used in the pump structure, then structural strength is achieved, but separate collection is required
Solution Approach 1:
The material composition parameter is changed from metallic materials to non-metallic materials (such as plastics or polymers). This substitution maintains the required structural strength for the pump components while enabling the entire container to be recycled together without separate collection processes, thereby improving ease of manufacture in terms of recycling.

AI summary
The present invention relates to an eco-pump type cosmetic container, and more particularly, to an eco-pump type cosmetic container having a shoulder portion and a shoulder bush, which are integrally formed and used, thereby preventing the shoulder bush from being separated from the shoulder portion, maximizing a pumping effect so that a space between the shoulder portion and the shoulder bush is completely sealed, and easily opening a seat portion by supporting the upper end of the shoulder bush to be in close contact with the seat portion, which is formed on an elastic member.
