Grip Container System With Barrier Additive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plastic blow-molded food and beverage containers are difficult to handle and do not effectively maintain the shelf life of stored products due to material limitations.
Innovation Solution
A food packaging container with molded grip surfaces and a layer of additive that forms a barrier to prevent oxygen and light from entering, enhancing handling ease and product protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional smooth plastic containers are used, then manufacturing is simple and material usage is minimal, but handling and gripping become difficult
Solution Approach 1:
The patent applies local quality by adding grip-enhancing features (recesses and textured surfaces) only at specific locations where gripping is needed, rather than making the entire container complex. This allows improved handling while maintaining simplicity in other areas of the container structure.
Solution Approach 2:
The patent uses curved and contoured surfaces in the grip areas, creating ergonomic shapes that conform to human hand geometry. These curved features provide natural grip points that improve handling ease without requiring complex mechanical additions to the container.
2Reliability
If traditional plastic materials are used, then manufacturing is easy and cost-effective, but oxygen and light barrier protection is insufficient
Solution Approach 1:
The patent employs composite materials by combining base plastic with oxygen barrier additives and light-blocking agents. This creates a multi-functional material that provides both structural integrity and protective barrier properties, extending shelf life while remaining compatible with existing manufacturing processes.
Solution Approach 2:
The patent modifies the chemical composition parameters of the plastic material by incorporating specific additives and barrier agents. These parameter changes enhance oxygen and light barrier properties without fundamentally altering the manufacturing process, maintaining ease of production while improving protection reliability.
3Duration of action of stationary object
If container material provides adequate oxygen and light barrier, then shelf life extends to 3 years, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates barrier properties during the initial material formulation and molding process, rather than requiring post-manufacturing treatments or assemblies. The oxygen and light barrier functionalities are built into the material itself before the container is formed, extending shelf life while avoiding additional manufacturing steps.
Applied Scientific Principles
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 container is easier to handle, particularly for users with limited grip strength, and extends the shelf life of products by up to 3 years through effective oxygen and light barrier functionality.
Implementation Method 1
The body includes a layer of an additive configured to form a barrier that prevents or reduces the ability of oxygen and/or light to move from an environment surrounding the container to an interior space of the container.

AI summary
A food packaging container is provided. The container comprises a molded body defining a longitudinal axis, and including a plurality of sides and a plurality of axial corners. Each corner has a recess including a first portion and a second portion. Each of the first portions includes an axial grip surface where the grip surfaces are aligned with the body in an orientation for gripping. In some embodiments, packaging products, containers, handles, tooling, applicators and methods are disclosed.
