Clean-Room Container Production With Sterilization-Proof Contact Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plants for producing and treating containers are susceptible to contamination from non-sterile components or materials, which can negatively impact the quality of the containers and products, despite maintaining clean room conditions.
Innovation Solution
The plant comprises sterilization-proof materials for components that come into direct contact with preforms or containers, along with a clean room sterilization device and preform sterilization device, controlled by a control unit to ensure sterility and minimize maintenance effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sterilization-proof material is used for components in direct contact with preforms or containers, then reliability of sterility is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies sterilization-proof material selectively only to components that come into direct physical contact with preforms or containers, rather than requiring all plant components to be made from such material. This localized application maintains sterility reliability where needed while reducing overall manufacturing costs.
Solution Approach 2:
The plant components are segmented into two categories: those in direct contact with preforms/containers (requiring sterilization-proof material) and those not in direct contact (where conventional materials suffice). This segmentation allows differential material selection based on sterility requirements.
2Object-affected harmful factors
If frequent sterilization is performed to maintain sterility, then purity is improved, but components experience wear and deterioration
Solution Approach 1:
Components are pre-treated with sterilization-proof material during manufacturing, providing built-in resistance to sterilization processes. This preliminary protection allows frequent sterilization without causing wear or deterioration to the components.
Solution Approach 2:
The sterilization-proof material coating acts as a sacrificial protective layer that can be repeatedly exposed to sterilization processes without compromising the underlying component structure, effectively allowing frequent sterilization cycles.
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
Ensures reliable production and treatment of containers under high cleanliness conditions by preventing contamination and reducing wear on components, while allowing for additional sterilization if necessary.
Implementation Method 1
the sterilization-proof material is resistant to exposure to a gaseous and/or liquid sterilization medium. The gaseous or liquid sterilization medium preferably has antibacterial and/or antiviral and/or fungicidal properties.
Implementation Method 2
In particular, it can be provided that the sterilization medium is H2O2 and/or O3 and/or peracetic acid.
Implementation Method 3
The plant comprises a clean room, a production machine for producing preforms, a blow-molding machine arranged downstream of the production machine for shaping the preforms into containers

AI summary
A plant for producing and treating containers includes a clean room, a production machine for producing preforms, a blow-molding machine arranged downstream of the production machine for shaping the preforms into containers and a container treatment machine arranged downstream of the blow-molding machine for treating the containers. The production machine, the blow-molding machine and the container treatment machine are arranged in the clean room, and each component of the production machine, the blow-molding machine and the container treatment machine that comes into physical contact with a preform or a container consists of or comprises sterilization-proof material.
