Stackable Blow Molded Container With Interlocking Base Recesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic blow molded containers lack structural strength to support stacked containers and do not efficiently utilize three-dimensional space or resist relative movement between adjacent containers in a stack.
Innovation Solution
A plastic blow molded container design with a cubic configuration, featuring upwardly sloped surfaces, troughs, ridges, concave groove, and convex rib surface sections that allow for secure stacking and resistance to side-to-side and rotational movement, enhancing structural strength and space efficiency in a two-dimensional array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional plastic blow molded containers are stacked one on top of another, then the containers can be transported in layers, but the containers lack structural strength to support the weight of additional stacked containers
Solution Approach 1:
The container is divided into distinct functional elements: a rigid base portion with recesses, a body portion, and an integrated handle structure. The base portion specifically segments the support function, providing dedicated recesses that receive and secure the necks of containers stacked below, distributing the load and preventing collapse.
Solution Approach 2:
The invention transitions from simple vertical stacking to a three-dimensional interlocking arrangement. The base portion recesses extend horizontally to receive necks from multiple containers simultaneously, creating a multi-dimensional support structure that enhances strength while enabling greater stacking capacity.
2Productivity
If containers are arranged in a tight fit three dimensional array on a pallet, then transport space is efficiently utilized, but conventional containers lack features to resist relative movement between adjacent containers
Solution Approach 1:
The necks of stacked containers are nested within the base portion recesses of the container below. This nesting arrangement secures the containers together vertically and laterally, preventing relative movement while enabling tight fit three-dimensional arraying on pallets for efficient transport.
Solution Approach 2:
The base portion recesses act as intermediary structures that mediate between adjacent containers. These recesses receive and hold the necks of containers from layers below, creating a stable interlocking system that resists relative movement throughout the entire stacked array.
3Quantity of substance
If conventional containers are stacked in multiple layers, then more containers can be transported, but the containers cannot support the combined weight of additional stacked containers
Solution Approach 1:
The container structure is segmented into a reinforced base portion with integrated recesses and an integrated handle structure. The base portion specifically handles the weight support function, with its rigid construction and recess geometry designed to distribute and bear the combined weight of multiple stacked containers.
Solution Approach 2:
The handle and base portion are merged into a single integrated structure. This integration creates a unified load-bearing system where the handle and base work together to support and distribute the weight of stacked containers, enhancing overall weight support capacity.

AI summary
A plastic blow molded pourable product container is constructed to support the combined weight of additional like containers stacked on top of the container, and is also constructed to efficiently use a three dimensional space occupied by a stack of containers and to resist relative movement between adjacent containers assembled together in a three dimensionally arrayed stack of the containers.
