Solution Overview
Problem
Existing liquid storage containers face challenges in efficiently using remaining liquid due to environmental pollution concerns and increased productivity and cost issues associated with negative pressure application and valve design.
Innovation Solution
A storage container design where a valve is not pre-cut but is cut when a liquid injection nozzle is inserted, ensuring perfect contact and blocking gaps to prevent leaks, while simplifying the process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a valve with a pre-formed cut-out groove is used to allow nozzle insertion, then the injection process becomes possible, but the valve cannot maintain complete contact with the tube during insertion/separation, causing liquid leakage
Solution Approach 1:
The valve is prepared in advance with a specific structure (elastic body with opening) that enables it to be cut during the injection process. The cut portion is designed to be elastically deformable, allowing it to be separated into first and second portions that can move relative to each other during nozzle insertion and separation, maintaining seal integrity throughout the process.
Solution Approach 2:
The valve transitions from a static sealed structure to a dynamic one during injection. The elastic cut portion is designed to deform elastically when the nozzle is inserted, allowing the first and second portions to separate and move. After injection, the valve returns to its original sealed state, dynamically adapting to the injection process while maintaining reliability.
2Ease of operation
If negative pressure is applied to the tube to expand it for liquid injection, then liquid injection becomes possible, but additional facilities are required and process time increases, reducing productivity
Solution Approach 1:
The complex negative pressure application system is completely removed from the injection process. Instead of using external vacuum equipment to expand the tube, the invention uses a simple nozzle that directly cuts through the valve and injects liquid into the tube, eliminating the need for negative pressure facilities and significantly reducing process time.
Solution Approach 2:
The mechanical negative pressure system is replaced with a direct mechanical cutting and injection process. The nozzle with its cutting edge directly penetrates the valve and tube, using mechanical force rather than pressure differential to achieve liquid injection, thereby simplifying the system and improving productivity.
3Ease of operation
If the valve is cut in advance to allow nozzle access, then injection is possible, but the cut-out groove remains open during insertion and separation, causing liquid leakage
Solution Approach 1:
The valve is prepared with an elastic cut portion that maintains its structural integrity while allowing controlled separation. The cut portion is designed in advance to be separable into first and second portions that can move relative to each other during nozzle insertion, then return to their original positions to maintain sealing, preventing liquid leakage throughout the process.
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 solution effectively prevents liquid leaks, simplifies the injection process, improves productivity, and reduces costs by eliminating the need for pre-cut valves and negative pressure systems.
Implementation Method 1
The tube made of an elastic material is characterized by being autonomously contracted by means of an elastic force thereof when the liquid stored in the tube is expanded.
Implementation Method 2
the valve is cut when a liquid injection nozzle is inserted into the tube, such that the valve may be perfectly in close contact with an outer surface of the liquid injection nozzle, and a gap between the liquid injection nozzle and the valve is perfectly blocked, which makes it possible to prevent a leak of the liquid

AI summary
Disclosed is a storage container, in which a valve coupled to an opening portion of a tube is not cut in advance, but the valve is cut when a liquid injection nozzle is inserted into the tube, such that a gap between the liquid injection nozzle and the valve may be perfectly blocked, thereby preventing a leak of a liquid. A storage container according to an embodiment of the present invention includes a tube made of an expandable or contractible elastic material, and a valve configured to be coupled to an upper end of the tube before a liquid is injected into the tube, in which the valve includes a ring-shaped support portion configured to be seated and supported at the upper end of the tube, and an elastic membrane extending from an end of the support portion and configured to close an opening portion of the tube.
