Solution Overview

Problem

The existing systems for withdrawing liquids from containers with closure caps are cumbersome, requiring multiple manipulations and separate assemblies, leading to tedious operations and storage challenges.

Innovation Solution

A closure cap with a clamping ring and flexible outlet pipe that integrates a dip tube and flow pipe, allowing for easy and rapid liquid withdrawal, with a clamping mechanism to secure the flow pipe and a sealing mechanism to ensure the container remains closed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional closure caps with separate dip tubes and delivery heads are used, then the container can be sealed and liquid can be withdrawn, but the withdrawal operation becomes tedious requiring multiple manipulations and separate assemblies

Engineering Contradiction:
Improveliquid withdrawal operationVSAvoidnumber of separate assemblies
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the dip tube and delivery head into a single integrated closure cap assembly. The flow pipe is directly connected to the cap body with the dip tube extending into the container, eliminating the need for separate delivery heads and multiple manipulation steps. This integration allows liquid withdrawal to occur directly through the cap structure itself.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The closure cap is designed to perform multiple functions: sealing the container, providing liquid withdrawal through integrated dip tube and flow pipe, and maintaining structural integrity under pressure. The single cap assembly serves as both closure and withdrawal mechanism, reducing the need for separate components.

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

2Adaptability or versatility

If traditional separate assemblies for container closure and delivery head are used, then each component can be optimized independently, but storage and management of multiple assemblies becomes constrained

Engineering Contradiction:
Improvecomponent optimizationVSAvoidstorage space for assemblies
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

By merging the closure cap and delivery system into a single integrated unit, the patent eliminates the need to store and manage separate cap and delivery head assemblies. The combined structure reduces storage volume while maintaining the functionality of both closure and liquid withdrawal operations.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the flow pipe is simply connected to the dip tube without retaining means, then the structure is simpler, but the flow pipe may detach during handling or pressurization

Engineering Contradiction:
Improveconnection structureVSAvoidflow pipe retention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent uses a flexible flow pipe that is retained by a clamping ring. The flexibility of the pipe allows it to be securely clamped while accommodating movement and pressurization forces. The clamping mechanism provides reliable retention without requiring complex rigid connection structures.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The clamping ring acts as an intermediary element between the flow pipe and the cap body. It provides a secure mechanical connection that prevents detachment during handling and pressurization while maintaining the simplicity of the overall structure. The clamping ring distributes forces and ensures reliable retention.

Inventive Principle:
Principle #24Intermediary (Mediator)
