Deformable Dispenser with Air Cushion for Multi-Component Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensers for cosmetics and chemicals are complex, inefficient in emptying, prone to oxidation due to air ingress, and unsuitable for long-term storage of multiple components, especially for multicomponent glues and sensitive cosmetics.
Innovation Solution
A deformable outer shell with a container arrangement and an air-filled intermediary space allows for even pressure transmission to multiple containers, featuring a diffusion-sealed exit and adjustable dispensing ratios, using thermoplastic materials and metal-coated foils for enhanced storage and mixing control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional dispensers with pump mechanisms are used, then substances can be dispensed from a single container, but the device complexity increases and two component dispensers are required for cosmetics or hair care products
Solution Approach 1:
The invention divides the container into multiple separate containers (first container for cosmetic substance, second container for hair dye substance) within a single dispenser body. Each container has its own outlet valve, allowing independent control of each substance without requiring complex pump mechanisms. This segmentation simplifies the dispensing mechanism while enabling multi-component delivery.
Solution Approach 2:
The patent implements a nested structure where multiple containers are arranged inside a common dispenser housing. The first and second containers are positioned side-by-side within the dispenser body, with their outlets leading to separate application nozzles. This nesting approach consolidates multiple substances into a single device without increasing mechanical complexity.
2Ease of manufacture
If collapsible tubes with dosing heads are used, then direct pressure loading is simple, but complete emptying is not achieved and residual amounts remain which are typically expensive
Solution Approach 1:
The patent employs flexible, deformable containers (first and second containers) made of thin-walled material that can be compressed uniformly from all sides. The container walls are designed to deform inward during pressure application, allowing the substance to be completely expelled toward the outlet. This flexible shell design eliminates dead zones and ensures complete emptying without requiring complex mechanical dosing mechanisms.
3Ease of manufacture
If collapsible tubes with dosing heads are used, then direct pressure loading is simple, but air can enter the interior of the container through the output opening which can lead to oxidation or spoiling of the substance
Solution Approach 1:
The patent introduces an air-filled intermediary space between the deformable container and the rigid dispenser wall. This air cushion acts as a mediator that transmits applied pressure uniformly to the container while preventing direct contact between the substance and external air. The intermediary space ensures that air enters only through controlled pathways during intentional dispensing, not during storage or pressure application, thereby preventing oxidation and spoiling.
Solution Approach 2:
The air-filled intermediary space creates a controlled atmosphere between the substance container and the external environment. By maintaining this intermediate air layer, the system prevents direct air-substance contact during storage and handling, reducing oxidation risks. The design ensures that substance exposure to air occurs only during controlled dispensing operations.
4Stress or pressure
If bag in bottle packaging with air filled intermediary space is used, then pressure can be transmitted evenly to the bag, but air can flow in to place the volume of the dispensed substance and the containers are not diffusion tight
Solution Approach 1:
The patent employs composite container construction with multiple layers including outer rigid housing, intermediate flexible container walls, and sealed outlet closures. The container arrangement combines deformable material for pressure transmission with diffusion-barrier properties. This composite structure maintains even pressure distribution while providing adequate protection against diffusion for the intended storage period.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates complete emptying, prevents oxidation, and allows for long-term storage and precise mixing of multiple components, ensuring the stability and freshness of sensitive cosmetics and glues.
Implementation Method 1
an air filled intermediary space is provided between the outer wall and the container arrangement and the pressure in parted upon the outer shell is evenly transmitted to the two or more containers of the container arrangement
Implementation Method 2
Through this balancing valve a corresponding amount of air flows into the intermediary space between the deformable outer wall of the outer shell and the container arrangement enclosed by the outer shell
