Dual-Bottle Dispenser with Intermediary Insert for Equal Liquid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-bottle containers for dispensing liquids face challenges in ensuring equal dispensing of liquids from separate compartments when subjected to varying pressures, leading to uneven filling and potential cross-contamination.
Innovation Solution
The design incorporates a dual-bottle container configuration where each bottle has a reservoir and an opening positioned side by side, with a mating surface and inner wall reinforcement, including an insert to inhibit flexing and ensure equal dispensing, and optional features like ribs and hinged caps to prevent cross-contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate individual containers are used for different liquids, then cross-contamination is prevented, but dispensing equality and consistency deteriorate
Solution Approach 1:
The container is divided into separate compartments for different liquids, with each compartment having its own opening. The partition wall with channels allows controlled interaction between compartments while maintaining separation, enabling equal dispensing from both sides without cross-contamination of the liquid sources.
Solution Approach 2:
A partition wall with channels acts as an intermediary structure between the two liquid compartments. This intermediary allows pressure equalization and controlled liquid flow while maintaining physical separation, ensuring both compartments dispense equally without direct cross-contamination.
2Object-affected harmful factors
If separate compartments of the same container are used, then cross-contamination is reduced, but dispensing equality under varying pressures deteriorates
Solution Approach 1:
The partition wall incorporates movable elements and channels that dynamically respond to pressure differences. When one side experiences higher pressure, the flexible partition or channels allow pressure equalization, automatically balancing the dispensing pressure on both sides without manual intervention.
Solution Approach 2:
The partition structure changes its physical parameters (flexibility, channel opening) in response to pressure variations. This allows the system to adapt to varying external pressures and maintain equal dispensing conditions on both sides despite changes in the operating environment.
3Ease of operation
If openings are positioned inside the container body, then dispensing is simplified, but cross-contamination risk increases
Solution Approach 1:
The openings are positioned on the outer surface of the container rather than inside the body. This dimensional relocation allows each opening to access its respective compartment through the partition wall channels, maintaining physical separation while enabling simple external dispensing operation.

AI summary
According to various aspects, exemplary embodiments are provided of multi-bottle containers and apparatus for dispensing liquids. In an exemplary embodiment, a container includes a first bottle and a second bottle coupled to the first bottle. The first bottle has a first reservoir for holding a first liquid and a first opening for dispensing the first liquid from within the first reservoir. The second bottle has a second reservoir for holding a second liquid and a second opening for dispensing the second liquid from within the second reservoir. An insert may be disposed between the bottles, which may be configured to inhibit flexing of one bottle without the other bottle to thereby help compensate for differences in pressure applied to one bottle relative to the other bottle when the container is squeezed and help the bottles dispense more equally.
