Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing containers with pumps or aerosol valves cannot be reused by replacing the pump valve or aerosol valve, as the concentrate is sealed under pressure, preventing users from doing so.

Innovation Solution

A refill content-accommodating container with a removable valve member and a tubular valve accommodating portion that allows for the attachment of a valve mechanism, featuring a communicating portion with a check valve to prevent external oxygen and bacteria ingress and pressurizing agent leakage, enabling the container to be reused.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the concentrate is sealed in a pressurized state in a container with a pump or aerosol valve, then the concentrate can be stored and dispensed, but the container cannot be reused by replacing the pump valve or aerosol valve

Engineering Contradiction:

Improvesealing reliabilityVSAvoidvalve replacement capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The container is divided into two separate functional parts: a reusable container body that remains sealed and pressurized, and a replaceable valve member that attaches to the container body when needed. This segmentation allows the container body to maintain its sealing integrity while enabling valve replacement for different dispensing needs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The valve mechanism is extracted from the permanent structure and made into a separate, removable valve member. This extracted valve member can be attached to or removed from the container body, enabling users to replace valves without compromising the sealed concentrate storage system.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a valve mechanism is permanently integrated into the pressurized container, then the container can dispense concentrate, but the concentrate cannot be replenished by detaching and reattaching a pump

Engineering Contradiction:

Improvedispensing functionVSAvoidconcentrate replenishment capability

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The valve member transitions from a static, permanently integrated component to a dynamic, removable component. This dynamic design allows the valve to be detached and reattached, enabling concentrate replenishment operations while maintaining ease of dispensing when the valve is attached.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the container is designed to allow valve replacement, then the container can be reused, but the sealed pressurized state may be compromised

Engineering Contradiction:

ImprovereusabilityVSAvoidsealing integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The container body is pre-prepared with a valve accommodating portion that includes sealing surfaces and structural features designed to maintain the pressurized sealed state. This preliminary design ensures that when a valve member is attached, the sealing integrity is preserved without compromising the reusability of the container.

Inventive Principle:

Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution allows for the stable storage of concentrates over long periods, prevents pressurizing agent leakage, and facilitates easy attachment and detachment of the valve member, enabling the reuse of the discharge device while maintaining the quality of the contents.

Implementation Method 1

a check valve which closes the gas introducing passage, allows a fluid flow to the container body, and blocks a fluid flow to the exterior

Methodology Applied

Scientific EffectCheck valve mechanism: Valve

Implementation Method 2

it is possible to store the concentrate stably for a long period preventing the invasion of external oxygen and bacteria by the pressure of the pressurizing agent

Methodology Applied

Scientific EffectPressure differential: Pressure Gradient
