Reactive Product Container With Integrated Suction Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current container configurations for reactive products in analysis laboratories result in significant losses and increased costs due to incomplete sampling, complex manual operations, and contamination risks, as they require lengthy sampling needles or manual insertion of flexible tubes.
Innovation Solution
A container design featuring a suction tube integrated into the container body with a puncturable closure membrane and a cap allowing for easy penetration by sampling and venting needles, enabling complete content sampling without prior cap removal or tube insertion, thus reducing product loss and manufacturing costs while enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a sampling needle having a length substantially corresponding to the height of the container is used, then the entirety of the container content can be sampled, but the sampling device becomes complicated and manufacturing costs increase
Solution Approach 1:
The suction tube is nested within the container body, with its first end portion attached to the closure member and its second end portion extending toward the bottom of the container. This nested configuration allows a regular-length sampling needle to access the entire container content through the suction tube's guidance, eliminating the need for an excessively long sampling needle while achieving complete content sampling.
Solution Approach 2:
The suction tube acts as an intermediary element between the sampling needle and the container content. By providing this intermediate structure with a guide opening at its first end, the sampling needle can efficiently reach the bottom of the container without requiring the needle itself to be as long as the container height, thus reducing device complexity while maintaining sampling completeness.
2Loss of substance
If a flexible sampling tube is used instead of a sampling needle, then the entirety of the container content can be sampled, but manual operations are complicated and contamination risks increase
Solution Approach 1:
The suction tube is pre-installed and attached to the closure member before the container is loaded into the storage device. The guide opening is pre-positioned at the first end of the suction tube, so that when the container is loaded, the sampling needle can immediately access the content through the pre-prepared pathway without requiring manual insertion of flexible tubes or removal of caps.
Solution Approach 2:
The container structure itself provides the sampling pathway through the suction tube and guide opening configuration. The container is designed to work with a standard sampling needle, allowing the system to perform complete content sampling automatically without requiring manual intervention to insert flexible tubes or remove protective caps, thereby simplifying operations and reducing contamination risks.
3Adaptability or versatility
If the cap is removed before loading the container, then the flexible sampling tube can be inserted, but the manual operations become more complex and contamination risks increase
Solution Approach 1:
The suction tube is pre-attached to the closure member with its guide opening positioned at the first end, creating a pre-prepared sampling pathway that remains sealed during storage and transport. This preliminary configuration eliminates the need to remove the cap or insert flexible tubes manually, as the pathway is already in place and protected until the sampling moment.
Solution Approach 2:
The container structure with the integrated suction tube and guide opening configuration enables the sampling operation to proceed automatically with a standard needle without requiring manual cap removal or tube insertion. The design itself provides the necessary adaptability for complete content sampling while maintaining reliability by keeping the pathway sealed and protected until needed.

AI summary
A container for a reactive product including a container body having a neck delimiting a neck opening; a closure member comprising a puncturable closure membrane which tightly seals off the neck opening; a suction tube located in the container body and comprising a first end portion attached to the closure member and a second end portion extending in the proximity of the bottom of the container body; and a cap attached to the neck and comprising a passage opening which is located facing the puncturable closure membrane and the first end portion of the suction tube, the cap being configured so as to enable the penetration of a sampling needle through the passage opening and the puncturable closure membrane such that the sampling needle is fluidly connected to the suction tube, and so as to enable the penetration of a venting needle through the passage opening and the puncturable closure membrane such that the venting needle is fluidly connected to an internal volume of the container body.
