Carton Handle With Yieldable Tabs Avoiding Bottle Neck Interference

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing carton designs with handle flaps can interfere with bottle necks, especially in tighter configurations like gable-style cartons, causing obstruction and potential damage during handling and storage.

Innovation Solution

The carton incorporates slot handles with foldable hand flaps that include an article receiving section, featuring yieldable tabs and reinforcing flaps, which can be folded inward to accommodate bottle necks, preventing interference and providing clearance for easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a slot handle with inwardly displaceable hand flap is used in a carton, then the handle provides easy gripping and handling, but the handle flap interferes with and hits the bottle neck when displaced inward

Engineering Contradiction:

Improvehandle grippingVSAvoidinterference with bottle neck

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The hand flap is segmented into multiple sections: an intermediate panel section that folds inward and yieldable tabs that can deflect independently. This segmentation allows the handle to provide gripping force while the tabs can move independently to avoid interfering with the bottle neck.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The yieldable tabs are designed with specific geometric parameters (length, width, thickness) that allow them to be flexible enough to deflect around the bottle neck while still providing structural support for the handle function.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If the carton is designed with a tighter configuration (gable-style carton), then the carton provides better stability and compactness, but the handle is located even closer to the bottle neck causing increased obstruction

Engineering Contradiction:

Improvecarton stabilityVSAvoidhandle obstruction

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The hand flap is divided into an intermediate panel section and yieldable tabs connected by a fold line. This segmentation allows the intermediate section to provide structural stability for the handle while the yieldable tabs can independently deflect to clear the bottle neck, even in tight gable-style carton configurations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The yieldable tabs are designed to be dynamically flexible, allowing them to deflect when the handle is grasped or when the carton is in a tight configuration, thereby avoiding static interference with the bottle neck while maintaining carton stability.

Inventive Principle:

Principle #15Dynamics

AI summary

A carton is defined for packaging a plurality of articles. The carton includes a plurality of carton walls at least one of which includes a slot handle that comprises a foldable hand flap. The foldable hand flap has an article receiving section for receiving a portion of an article in the carton when the at least one foldable hand flap is folded inwardly of the carton.
