Vacuum Sealing Lid for Container Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resealable containers require contents to be removed from transport or packaging containers for storage, leading to resource wastage and premature spoilage due to exposure to the atmosphere.
Innovation Solution
A device featuring a lid with a form-fitting valve holder that allows for vacuum sealing, enabling continuous use of containers while protecting contents from spoilage, with a valve that can be inserted and sealed using a pump, and a hygiene/protective cap for added protection and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contents are removed from transport containers for storage in separate containers, then contents can be protected from spoilage, but resources are wasted and repackaging is required
Solution Approach 1:
The invention merges the transport container and storage container into a single integrated system. The lid with vacuum valve is designed to seal the container opening, allowing the same container to serve both transport and storage functions without requiring content removal or repackaging.
Solution Approach 2:
The container-lid system is designed to perform multiple functions: transport, sealing, and vacuum preservation. The lid with integrated vacuum valve allows the container to maintain protective vacuum sealing during both transport and storage phases, eliminating the need for separate packaging operations.
2Reliability
If contents are removed from transport containers for storage, then contents can be protected from atmospheric exposure, but time is lost during repackaging
Solution Approach 1:
The vacuum sealing capability is built into the container lid itself, allowing vacuum preservation to be established before contents are fully utilized. This preliminary vacuum sealing eliminates the need for time-consuming repackaging operations later, as the container remains protected throughout its use cycle.
Solution Approach 2:
By combining the vacuum sealing function directly into the transport container lid, the invention eliminates the separate repackaging step. The same container that transports contents can maintain vacuum protection during storage without requiring content removal or additional packaging operations.
3Duration of action of moving object
If a valve is added to the lid for vacuum sealing, then continuous container use is enabled, but device complexity increases
Solution Approach 1:
The valve is integrated directly into the lid structure, merging the sealing and vacuum functions into a single component. This integration enables continuous container use by allowing vacuum evacuation without requiring separate valve mechanisms or additional parts, thus minimizing the increase in device complexity.
Solution Approach 2:
The lid is designed as a multi-functional component that combines the closure function with integrated vacuum valve functionality. This universal design enables the lid to both seal the container and facilitate vacuum evacuation, allowing continuous use without adding significant structural complexity.
