Discharge Container Single Button Dual Pumping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for heterogeneous cosmetic contents require separate operation of each pumping member, leading to user inconvenience when trying to mix and use multiple contents simultaneously, as physical and chemical reactions can cause coagulation, precipitation, discoloration, or decomposition if mixed prematurely.
Innovation Solution
A discharge container design where a single button member operates both pumping members, with a button support guiding vertical movement, allowing simultaneous discharge of two contents through separate discharge holes, ensuring stable button operation and preventing mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pair of operating members are used to operate each pumping member separately, then the pumping operation can be controlled individually, but user convenience deteriorates when trying to mix and use multiple contents simultaneously
Solution Approach 1:
The patent combines two separate operating members into a single button member that can operate both pumping members simultaneously. The button member is pressed by a single user action, which transmits force through a common pressing part to both pumping members, eliminating the need for separate operating members and improving user convenience.
Solution Approach 2:
The button member serves multiple functions: it operates both the first and second pumping members simultaneously, and its pressing part can be pressed from multiple directions (front and rear) to control the discharge of different contents. This multi-functionality reduces the number of operating members needed while maintaining operational control.
2Stability of the object's composition
If heterogeneous contents are stored in separate containers, then physical and chemical reactions are prevented, but user convenience deteriorates when using contents that have synergy effect when mixed
Solution Approach 1:
The patent divides the container into separate compartments (first container and second container) that store different heterogeneous contents independently. Each compartment has its own discharge path with separate discharge holes, preventing premature mixing while allowing simultaneous controlled discharge when needed, thus maintaining both stability and usability.
Solution Approach 2:
The container transitions from a static separated storage state to a dynamic simultaneous discharge state. The pumping members and button member enable the system to switch between maintaining separate contents (preventing reactions) and discharging both contents simultaneously (enabling mixing for synergy effect), providing dynamic control over content interaction.
3Ease of operation
If a single button member operates both pumping members, then user convenience is improved, but button operation stability deteriorates without proper guidance
Solution Approach 1:
The button support acts as an intermediary between the button member and the housing. It provides guiding surfaces that constrain the button member's movement to a vertical path only, preventing lateral displacement or rotation. This intermediary structure ensures stable and reliable operation of the button member while maintaining the simplified single-button interface.
Solution Approach 2:
The button support provides localized guidance features (guiding surfaces) at specific locations where the button member makes contact. These localized structural features ensure proper alignment and stable operation only where needed, without complicating the overall button design or user interaction.

AI summary
The present invention disclosed herein relates to a discharge container for heterogeneous contents, which configured such that the pumping operations of a first pumping member and a second pumping member are achieved by manipulating one button member, and a first content and a second content are simultaneously discharged separately to be used, wherein a button support for supporting the button member at both sides of the button member guides the vertical movement of the button member, whereby the button operation can be stably performed.
