Liquid Discharge Container with Compressible Resilient Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid discharge containers for cosmetics are costly due to complex structures and numerous components, and they often leave residual contents at the bottom, leading to incomplete exhaustion.
Innovation Solution
A simplified liquid discharge container design featuring a container body with a discharge port, an intermediate joint with a one-way check valve, and a shape resilient body that compresses to push contents through the discharge port, allowing complete exhaustion with fewer parts and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional dispensing device with multiple components (button, shaft, spring, fixed cap, stem, piston, opening and closing member, housing) is used, then the liquid can be discharged through a nozzle, but the manufacturing cost increases due to the large number of components and complicated structure
Solution Approach 1:
The patent combines multiple components into a simplified integrated structure. The container body integrates the functions of the button, shaft, and housing into a single pressed-actuation mechanism. The closure member combines the piston, opening and closing member, and nozzle into a single movable component that performs both sealing and discharge functions.
Solution Approach 2:
The closure member serves multiple functions simultaneously: it acts as a piston to pressurize the liquid, as a seal to close the discharge port when not in use, and as a nozzle structure for liquid ejection. The container body itself serves as both the storage vessel and the actuation mechanism through simple pressing motion.
2Ease of operation
If a conventional dispensing device with multiple components is used, then the liquid can be discharged through a nozzle, but the manufacturing cost is considerably high
Solution Approach 1:
The patent combines multiple components into a simplified integrated structure. The container body integrates the functions of the button, shaft, and housing into a single pressed-actuation mechanism. The closure member combines the piston, opening and closing member, and nozzle into a single movable component that performs both sealing and discharge functions.
Solution Approach 2:
The invention employs simple, easily manufacturable components that can be produced at low cost. The container body and closure member are designed as simple plastic or metal parts that can be mass-produced through injection molding or stamping, replacing complex assembled mechanisms with inexpensive single-piece components.
3Productivity
If the contents are discharged using the conventional dispensing device, then the liquid cosmetics can be discharged through the nozzle, but the contents located on the bottom of the container remain and are not completely exhausted
Solution Approach 1:
Instead of drawing liquid up from the bottom of the container through suction (conventional method), the invention inverts the approach by pressing the closure member downward to push liquid from the top toward the discharge port. This downward pressing action effectively expels even the liquid at the bottom of the container, achieving complete exhaustion without residual contents.
Solution Approach 2:
The closure member is designed to move automatically under the applied pressure, pressing the liquid toward the discharge port without requiring additional mechanical components. The simple pressed-actuation mechanism allows the user to directly transfer force to the liquid, ensuring complete discharge through self-service action.
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 design enables easy and complete discharge of contents while reducing manufacturing costs by using fewer parts and ensuring all contents are emptied, improving user convenience.
Implementation Method 1
the shape resilient body is compressed and thus the internal air of the shape resilient body is moved upward
Implementation Method 2
the shape resilient body is compressed and thus the internal air of the shape resilient body is moved upward through the check valve
Implementation Method 3
a one-way check valve formed at the center of the intermediate plate member to allow upward movement of the air and prevent downward movement of the air
Implementation Method 4
the shape resilient body is formed to be compressible and recoverable with a vent hole at the lower center of the shape resilient body

AI summary
A liquid discharge container includes a container body having a space in which liquid contents are accommodated, a discharge port through which the contents are discharged, and a push plate for supporting the contents and pushing up the contents. An intermediate joint formed of an intermediate plate member is coupled to a lower side of the container body. A one-way check valve is formed at the center of the intermediate plate member, and a lower fastening member is formed at a lower portion of the intermediate plate member. A cylindrical bottom support is coupled to the lower fastening member of the intermediate joint. A shape resilient body is coupled to a lower portion of the intermediate joint, and is compressible and recoverable with a vent hole at the lower center of the shape resilient body, and that comes in contact with the bottom support.
