Carton Handle Structure with Grip Member and Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carton designs for multi-packs lack efficiency in material usage, strength, and waste reduction, while also failing to provide an effective and accessible carrying handle that can be easily deployed and used by consumers.
Innovation Solution
A carton design featuring a handle structure with a grip member and a handle strap, where the grip member is mounted on the strap and apertures are strategically placed to define the edges, allowing for easy deployment and use, and a reinforcing panel hingedly connected to the strap for added strength, all while minimizing material usage and allowing for stacking and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a carrying handle is added to the carton, then consumer accessibility and ease of operation are improved, but device complexity and material usage increase
Solution Approach 1:
The handle structure is divided into distinct functional components: a grip member struck from the panel for hand contact, and a separate handle strap disposed below the panel for structural support and carrying function. This segmentation allows each component to be optimized independently while reducing overall complexity.
Solution Approach 2:
The handle strap is extracted as a separate element disposed below the panel, allowing the grip member to be simply struck from the panel surface. This extraction simplifies the grip member design while providing the necessary carrying function through the separate strap structure.
2Strength
If the handle structure includes multiple components (grip member, handle strap, reinforcing panel), then strength and reliability are improved, but manufacturing complexity increases
Solution Approach 1:
Multiple handle components (grip member, handle strap, and reinforcing panel) are merged into a single integrated structure that can be formed from one piece of material. The reinforcing panel is hingedly connected to the handle strap, creating a unified assembly that maintains strength while simplifying manufacturing.
Solution Approach 2:
The handle structure utilizes composite construction with the grip member, handle strap, and reinforcing panel forming a multi-layer composite assembly. This composite structure provides enhanced strength while being manufacturable as an integrated unit, reducing the need for separate assembly operations.
3Ease of operation
If apertures are struck from the panel to define the grip member edges, then ease of operation and handling are improved, but material usage and waste increase
Solution Approach 1:
Apertures are strategically positioned at specific locations where the grip member edges require definition for proper hand contact. This localized modification provides the necessary grip characteristics while minimizing the overall material removed from the panel, reducing waste.

AI summary
A carton for packaging one or more articles includes a plurality of walls including a top wall, a base wall, a first side wall and a second side wall forming a tubular structure. One of the plurality of walls includes a handle structure defined in it. The handle structure includes a grip member struck from one of the plurality of walls and a handle strap. The grip member is mounted on the handle strap. A first aperture is struck from the one of the plurality of walls. The aperture is disposed adjacent to a first end of the grip member so as to define a first end edge of the grip member. The first aperture defines a portion of an opening in the one of the plurality of walls. In the opening, a portion of the handle strap may be received.
