Stackable Bottle Handle Neck Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of the bottle form due to integrated handles increases production costs and affects the relationship between outer dimensions and capacity, leading to less efficient material use and potential weaknesses in bottles with handles.
Innovation Solution
Attaching the handle to the bottle neck with annular fixing means and a recess dimensioned to surround the handle in a stacked position, allowing for a simpler bottle form independent of the handle and maintaining stackability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is integrated into the bottle body, then the handle functionality is improved, but the bottle form complexity increases and production costs rise
Solution Approach 1:
The handle is separated from the bottle body and attached to the bottle neck as an independent component. This segmentation allows the bottle body to maintain a simple, efficient blow-moulded form while the handle provides the necessary carrying functionality. The handle can be produced separately and attached through simple fixing means such as adhesive or mechanical attachment.
2Ease of operation
If the handle is integrated into the bottle body, then the handle functionality is improved, but the relationship between outer dimensions and capacity deteriorates
Solution Approach 1:
By separating the handle from the bottle body, the bottle's outer dimensions are optimized for capacity without the additional material and space required for an integrated handle. The bottle body can be designed with optimal wall thickness and volume efficiency, while the attached handle adds minimal dimensional impact compared to an integrated design.
3Ease of operation
If the handle is integrated into the bottle body, then the handle functionality is improved, but the bottle production efficiency deteriorates
Solution Approach 1:
The bottle body can be produced through efficient blow-moulding processes without the complexity of integrated handle formation. The handle is attached separately in a simple, automated process that does not interfere with the primary bottle forming operation, thereby maintaining high production efficiency.
Solution Approach 2:
The handle functionality is extracted from the bottle body and implemented as a separate attached component. This allows the bottle body to be produced using standard, high-efficiency blow-moulding techniques without the need for complex multi-step integrated handle formation processes.
4Ease of operation
If the handle is integrated into the bottle body, then the handle functionality is improved, but the bottle reliability deteriorates
Solution Approach 1:
Separating the handle from the bottle body eliminates the creation of weak points in the bottle wall that would result from integrated handle formation. The bottle body maintains uniform wall thickness and structural integrity, while the handle is attached to the neck portion where it does not compromise the main body strength.

AI summary
Set comprising at least one first and one second stackable bottle 13, 14 in which each bottle 1 has a handle 12, each bottle 1 has a base part 7 with a central base part 10 and a peripheral base part 9, wherein said central base part 10 comprises a recess 11 that is dimensioned such that the recess 11 of the first bottle surrounds a bottle cap 3 and a bottle neck 4 of the second bottle in a stacked position in which a shoulder part 5 of the second bottle rests against the peripheral base part 9 of the first bottle, wherein said handle 12 is attached to the bottle neck 4 and comprises a gripper part 17 and wherein the recess 11 is dimensioned such that the recess 11 of the first bottle also surrounds the handle 12 attached to the second bottle in said stacked position.
