Solution Overview

Problem

There is a need to minimize container fabrication and shipping costs while maintaining container durability for lightweight shippable containers used in handling and dispensing various products, as they often compromise on structural rigidity and integrity.

Innovation Solution

The use of dispensers with collar engagement, closure engagement, and body engagement portions that securely interact with shippable containers to prevent rotation and facilitate dispensing when the container is inverted, ensuring durability and efficient content dispensing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If lightweight containers are used to minimize fabrication and shipping costs, then manufacturing cost and shipping cost are reduced, but structural rigidity and integrity deteriorate

Engineering Contradiction:
Improvemanufacturing costVSAvoidstructural rigidity
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The system divides the container structure into distinct functional segments: the lightweight shippable container body and the separate durable dispenser unit. The dispenser acts as an independent structural component that provides the necessary rigidity and strength during dispensing operations, while the container body can remain lightweight for shipping efficiency. This segmentation allows each component to be optimized for its specific function without compromising overall system performance.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If lightweight containers are used to minimize shipping costs, then shipping cost is reduced, but container durability deteriorates

Engineering Contradiction:
Improveshipping costVSAvoidcontainer durability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The dispenser serves as an intermediary structure between the lightweight container and the dispensing operation. It provides the necessary durability and structural support during handling and dispensing, protecting the lightweight container from stresses that would otherwise compromise its integrity. The dispenser acts as a mediator that enables the lightweight container to fulfill its function without requiring the container itself to be heavily constructed.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If containers are designed for inverted dispensing, then dispensing functionality is improved, but handling complexity increases

Engineering Contradiction:
Improvedispensing functionalityVSAvoidhandling complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The dispenser is specifically designed to accommodate inverted positioning of the container, with engagement features oriented for top-down insertion and securing. The collar engagement portion and closure engagement portion are configured to function when the container is inverted, enabling reliable dispensing in this orientation while maintaining relatively simple handling procedures through intuitive engagement mechanisms.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A dispenser for a shippable container is provided, where the shippable container has a hollow body, an opening, a collar adjacent the opening, and a closure sealing the opening. The dispenser has a collar engagement portion configured to engage the collar of the shippable container, a closure engagement portion configured to engage the closure of the shippable container, and a body engagement portion configured to engage a portion of the hollow body of the shippable container. An aperture in the dispenser is configured to dispense contents from the hollow body of the shippable container. The dispenser can be configured to dispense contents from the hollow body of the shippable container when the shippable container is in an inverted position.
