Solution Overview

Problem

Conventional flexible containers lack the ability to conveniently and accurately dispense a metered dose of liquid content, failing to provide a practical solution for controlled fluid dispensing.

Innovation Solution

A flexible container design featuring four panels made of multilayer film, forming a body, neck, and handle with a dispensing pump attached to the neck, allowing for metered dosing and serving as a handle for carrying the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a flexible container uses conventional design without integrated dispensing mechanism, then manufacturing simplicity and cost-effectiveness are maintained, but the ability to conveniently and accurately dispense metered dose of liquid content is lost

Engineering Contradiction:
Improveconvenience of dispensing metered doseVSAvoidstructural complexity of container
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the flexible container body with a rigid fitment assembly that includes an integrated dispensing pump mechanism. The pump is directly attached to the fitment, merging storage and metered dispensing functions into a single unified structure, enabling convenient metered dose delivery without requiring separate dispensing equipment

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fitment assembly serves multiple functions: it provides a sealed closure for the flexible container, acts as a mounting structure for the dispensing pump, and enables metered dose dispensing through the integrated pump mechanism. This multi-functionality resolves the contradiction by adding dispensing capability without proportionally increasing overall complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If a flexible container integrates a dispensing pump, then the ability to accurately dispense metered dose is achieved, but device complexity increases

Engineering Contradiction:
Improveaccuracy of metered dose dispensingVSAvoidstructural complexity of container
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The dispensing system is segmented into distinct functional components: the flexible container body, the rigid fitment, and the integrated pump mechanism. This segmentation allows each component to be optimized independently while maintaining overall simplicity, achieving accurate metered dispensing through the specialized pump design without unnecessarily complicating the entire container structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fitment acts as an intermediary structure that bridges the flexible container body and the rigid dispensing pump. This intermediate component provides a stable mounting platform for the pump while maintaining compatibility with the flexible container, enabling accurate metered dispensing without requiring direct integration that would increase overall complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If a flexible container uses multilayer film panels to form body, neck, and handle, then structural integrity and functionality are improved, but manufacturing complexity increases

Engineering Contradiction:
Improvestructural integrity of containerVSAvoidmanufacturing simplicity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent specifies particular multilayer film constructions with defined layer compositions and properties to achieve the required structural integrity for supporting the rigid fitment and pump assembly. By optimizing film parameters such as layer thickness, material composition, and sealing characteristics, the container achieves necessary strength while maintaining manufacturability through established flexible packaging techniques

Inventive Principle:
Principle #35Parameter changes

AI summary

A flexible container (10) is disclosed. The flexible container (10) includes four panels (18, 20, 22, 24), each panel comprising a flexible multilayer film. Each flexible multilayer film is composed of a polymeric material. The four panels form (i) a body, (ii) a neck, and (iii) a handle. The handle (12) has an upper handle portion (12a) and a pair of spaced-apart legs (13, 15). The legs extend from the upper handle portion to the body on opposing sides of the neck. The flexible container includes a fitment (70) sealed to the neck. The flexible container includes a dispensing pump (100) attached to the fitment. The flexible container can provide a metered dose from a dispensing pump and the dispensing pump can also function as a handle to hand-carry the flexible container.
