Resin Container Curved Pipe Offset Recess for Complete Liquid Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resin containers experience significant residual liquid amounts due to irregularities on the bottom plate and expansion of the container during liquid discharge, leading to inefficiencies in both suction and pressure feeding systems, resulting in wasteful disposal of valuable industrial drugs.
Innovation Solution
A resin container design featuring a recessed portion on the bottom plate offset from the outlet port's axis, combined with a gutter-shaped groove and a curved pipe that maintains contact with the recessed portion's boundary, ensuring the pipe's lower end remains pressed against the boundary even during expansion, allowing for complete liquid discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pipe is lowered straightly toward the bottom plate, then the structure is simple, but residual liquid remains on the recessed surface due to irregularities on the bottom plate
Solution Approach 1:
The pipe is configured to be curved rather than straight, allowing it to follow the contour of the recessed portion on the bottom plate. This curvature enables the pipe to maintain contact with the lowest point of the recessed area, ensuring complete liquid discharge while keeping the overall structure relatively simple.
Solution Approach 2:
The pipe's lower end is specifically positioned to contact the boundary of the recessed portion, creating a localized adaptation to the bottom plate's irregularities. This local modification allows the pipe to reach the deepest point for liquid discharge without requiring complete redesign of the entire pipe structure.
2Speed
If the pressure feeding system is used to discharge liquid, then discharge speed increases, but the bottom plate expands outward causing the pipe to distance from the bottom plate
Solution Approach 1:
The pipe is designed with flexibility to adapt to the dynamic expansion of the bottom plate during pressure feeding. The curved configuration and strategic positioning allow the pipe to maintain contact with the recessed portion boundary even as the bottom plate expands outward under pressure.
Solution Approach 2:
The pipe is pre-configured to contact the boundary of the recessed portion before pressure feeding begins. This preliminary positioning ensures that when the bottom plate expands during pressure feeding, the pipe remains in contact with the expanding surface and continues to discharge liquid effectively.
3Device complexity
If the pipe lower end is positioned at the center of the bottom plate, then the structure is symmetric and simple, but liquid on the recessed surface cannot be discharged
Solution Approach 1:
The pipe is intentionally positioned asymmetrically, with its lower end contacting the boundary of the recessed portion rather than the center of the bottom plate. This asymmetric positioning is specifically designed to reach the recessed area where liquid accumulates, ensuring complete discharge despite the added complexity.

AI summary
A resin container includes a main body in which a bottom plate, a cylindrical body portion, and a ceiling plate are integrally molded, and a pipe which is inserted into the main body through an outlet port opened on the ceiling plate. The main body includes a recessed portion which is formed on the bottom plate, of which center is not located on a virtual axis line extending from a center of the outlet port in a container height direction, and a gutter-shaped groove portion which is formed on the bottom plate and reaches the recessed portion. The pipe is curved from an upper end to a lower end, and the lower end of the pipe is pressed against a boundary between an inner circumferential surface of the recessed portion at a side opposite to a side of the outlet port and a bottom surface of the recessed portion.
