Packaging Container Handle Protrusion and Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging containers require larger sizes to accommodate handles, leading to increased storage needs and material costs, and pose operational challenges when handling large and heavy objects due to narrow gaps between the container and the object, which can result in accidents and back pain during handling.
Innovation Solution
A packaging container design featuring a plastic bag with integrated handle portions that protrude beyond the object's surface, allowing for easier handling and reduced container size, along with a cushioning member that supports the handle and object during removal, enabling a user to lift the bag with one hand and reducing the risk of accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container size is increased to accommodate handles, then the handles can be properly positioned, but the storage needs and material costs increase
Solution Approach 1:
The handle is nested within the packaging bag structure, with the bag containing the handle portion that protrudes from the object. This allows the handle to be accommodated within the existing container volume without requiring additional space, thereby resolving the contradiction between handle positioning and container size.
2Ease of operation
If the container size is increased to accommodate handles, then the handles can be properly positioned, but the material costs increase
Solution Approach 1:
The handle is integrated into the packaging bag structure, allowing it to be contained within the existing container without requiring additional materials for an separate handle mounting structure. This reduces material costs while maintaining proper handle positioning.
3Volume of stationary object
If the gap between container and object is narrow, then the container size is reduced, but operational challenges arise when handling large and heavy objects
Solution Approach 1:
The handle protrudes from the object surface before the object is placed in the container, providing a grip point in advance. This preliminary positioning of the handle allows users to easily grasp and lift the object without needing to insert hands through narrow gaps, thereby improving ease of operation while maintaining compact container size.
4Volume of stationary object
If the gap between container and object is narrow, then the container size is reduced, but accidents and back pain may occur during handling
Solution Approach 1:
The handle protrudes from the object surface before containment, providing an accessible grip point that eliminates the need to insert hands through narrow gaps. This preliminary handle positioning ensures safe and ergonomic handling, preventing accidents and back pain while maintaining compact container dimensions.

AI summary
A packaging container includes an outer container, a packaging bag, and an inner packing member. The outer container has a box-like shape and has a containing space and a passage opening. The packaging bag is contained in the outer container in a state in which the packaging bag contains an object. The packaging bag includes a containing portion, an opening portion formed in the containing portion and allowing the object to pass therethrough, and a handle portion graspable by a user. The inner packing member is disposed between the object and the passage opening and contained in the containing space. At least part of the handle portion is disposed on the passage opening side of the inner packing member, and the handle portion moves toward the passage opening together with the inner packing member when the inner packing member is being removed from the outer container.
