Blow-Molded Container Handle and Carton Window for Fill Level Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food packaging containers are difficult to handle and dispense due to their shape and size, and lack effective visual indicators for determining fill levels, which complicates stacking and comparison of filled containers.
Innovation Solution
A packaging system comprising a container with a handle and a carton that includes a wall with an opening aligned to provide visual indicia of the fill level, allowing for easier handling, stacking, and comparison of the container's volume, featuring a blow-molded plastic design with a spout and manual grip, and a method of assembling the packaging system by cutting and folding sheets to create the carton and aligning the opening with the container's fill level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a blow-molded plastic container is used for food packaging, then the container can be manufactured in various shapes and sizes, but it becomes difficult to handle and dispense the products
Solution Approach 1:
The container is segmented by adding integral handles that divide the container body into manageable sections, allowing users to grip and control the container more easily during handling and dispensing operations
Solution Approach 2:
The handle acts as an intermediary element between the user's hand and the container body, providing a comfortable grip interface that facilitates easier handling and control of the container during dispensing
2Device complexity
If traditional packaging without visual indicators is used, then the packaging structure remains simple, but it lacks effective visual indicators for determining fill levels
Solution Approach 1:
The carton incorporates a window or opening that allows the color and appearance of the product inside to be visible, providing visual information about fill level and product condition without adding complex mechanical indicators
Solution Approach 2:
The packaging design adds a visual dimension by creating a window/opening in the carton that permits observation of the product inside, enabling fill level determination through visual inspection rather than requiring physical measurement
3Productivity
If containers are stacked for transport and storage, then space efficiency improves, but visual verification of fill levels becomes difficult
Solution Approach 1:
The window or opening in the carton allows the product's visual characteristics to show through, enabling fill level verification even when containers are stacked, as the visual information penetrates through the packaging structure
Solution Approach 2:
By adding the visual dimension through a window/opening in the carton structure, the design enables fill level assessment to occur through the packaging material itself, maintaining visibility functionality while preserving stacking capabilities
