Extruding Container Hole Portion Air Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing application material extruding containers face challenges in preventing air from entering between the application material and the extruding portion, leading to potential leaks due to temperature changes, which compromises the airtightness and stability of the container.
Innovation Solution
The container design includes a filling member with a hole portion that allows air to be discharged between the application material and the extruding portion, ensuring airtightness by guiding the application material out of the filling area through this passage, and utilizing a piston that moves to securely expel air, thereby preventing leaks and volatilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the extruding portion is inserted into the filling member to come into close contact with the application material, then the airtightness is improved, but air may become trapped between the extruding portion and the application material
Solution Approach 1:
The passage portion is pre-formed in the filling member to provide a predetermined air discharge path. When the extruding portion is inserted, air can automatically escape through this pre-established passage without requiring additional actions, thus preventing trapped air while maintaining close contact for airtightness.
Solution Approach 2:
The passage portion acts as an intermediary element that mediates between the need for close contact (airtightness) and the need to eliminate trapped air. It provides a controlled pathway that allows air to escape while the extruding portion maintains its sealing function.
2Object-generated harmful factors
If a passage portion is added to discharge air, then trapped air is prevented, but the container structure becomes more complex
Solution Approach 1:
The passage portion is integrated into the filling member structure itself, merging the air discharge function with the existing container wall. This combination approach adds the necessary air discharge capability while minimizing overall structural complexity by avoiding separate components.
3Object-generated harmful factors
If the extruding portion is positioned to maximize air discharge, then air escape is improved, but the lubricating material may be insufficient for sliding portions
Solution Approach 1:
The position of the extruding portion is optimized to balance two parameters: air discharge efficiency and lubricating material availability. By adjusting the insertion depth and positioning relative to the passage portion, the system achieves sufficient air escape while ensuring adequate lubricating material reaches the sliding portions for reliable operation.
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
This design effectively inhibits air from entering the container, preventing leaks and maintaining airtightness, even with volatile materials, by ensuring the application material is securely discharged and used as a lubricant within the container.
Implementation Method 1
a part of the application material is flowed out of the filling area through the hole portion
Implementation Method 2
a part of the application material is flowed out of the filling area through the hole portion
Implementation Method 3
the piston is inward inserted to the filling member while securely discharging the air between the application material and the extruding portion out of the filling area via the hole portion
Implementation Method 4
it is possible to make the application material flowed out of the passage portion serve as a lubricating material for a sliding portion (for example, a threaded portion) within the container

AI summary
The invention provides an application material extruding container which more securely inhibits the air from standing between an application material and an extruding portion. The application material extruding container is provided with a filling member (1) which has a filling area (1x) filled with an application material (M), a piston (7) which is inward inserted so as to be brought into close contact with the filling member (1) and constructs a rear end of the filling area (1x), and a hole portion (11e) which is provided in the filling member (1) and extends so as to be communicated with an outer side of the filling member (1) from the filling area (1x), a front end surface of the piston (7) is arranged in front of a rear end (ER) of an opening (11in) of the hole portion (11 e) in a state in which the piston (7) is at a backward moving limit, and a part of the application material (M) is flowed out of the filling area (1x) while passing through the hole portion (11 e). In other words, when the piston (7) is assembled in the filling member (1), the piston (7) is inward inserted to the filling member (1) while securely discharging an air (A) between the application material (M) and the piston (7) out of the filling area (1 x) via the hole portion (11 e), until the application material (M) is flowed out of the filling area (1 x) via the hole portion (11 e).
