Tabbed Preform Alignment for Multi-Barrier Bottles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bottle production methods are inefficient in terms of material usage and often result in misalignment between interior and exterior barriers, leading to structural insecurity in multi-barrier bottles.
Innovation Solution
A tabbed preform design that includes elongate bodies with preform extension pieces and beads, allowing for precise alignment and reduced material usage by fitting into recesses within the exterior barrier, ensuring proper positioning and secure sealing during the bottle formation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current bottle production methods are used, then bottles can be produced, but material usage is inefficient and barriers are misaligned
Solution Approach 1:
The preform is segmented into distinct functional zones: an elongate body for insertion into the barrier cavity, preform extension pieces (tabs) for alignment with recesses, and beads for sealing. This segmentation allows each component to perform its specific function optimally, ensuring precise alignment while minimizing material usage.
Solution Approach 2:
The preform extension pieces act as intermediaries between the preform and the exterior barrier. These tabs fit into corresponding recesses in the barrier, serving as alignment features that ensure precise positioning of the preform relative to the barrier during the forming process.
2Strength
If current bottle production methods are used, then bottles can be produced, but structural security is compromised due to misalignment
Solution Approach 1:
Alignment features (preform extension pieces and recesses) are incorporated into the preform design before the forming process. This preliminary configuration ensures that when the preform is inserted into the barrier cavity, proper alignment is automatically achieved, ensuring structural security from the outset.
Solution Approach 2:
The preform is nested within the exterior barrier, with the elongate body extending into the barrier cavity. The preform extension pieces are received within recesses in the barrier, creating a nested configuration that ensures both alignment and structural integrity of the multi-barrier bottle.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tabbed preform design minimizes material usage while ensuring accurate alignment and structural integrity of multi-barrier bottles, enhancing the strength and efficiency of the bottle production process.
Implementation Method 1
The at least one preform extension piece is sized and shaped to correspond to a size and a shape of the recess
Implementation Method 2
a plurality of beads extending from the elongate body around a circumference of the elongate body, where the plurality of beads are located between the first and second preform extension pieces and the top surface of the elongate body and maintain a positioning of the tabbed preform with respect to the first barrier such that the first barrier is in contact with the at least one bead
Implementation Method 3
a second barrier formed from a blow molded tabbed preform
