Sealing Container With Independent Discharge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing containers make it difficult for users to control the timing of content discharge due to the bulging of the sealing film when opening, leading to unpredictable liquid flow and potential obstruction by the protruding unit.
Innovation Solution
A sealing container design with a movable opening mechanism that allows for independent control of the timing of content discharge, featuring a blade to create a cut in the sealing film, a space to prevent contact with the container's inner surface, and a check valve to prevent reverse flow, enabling smooth and controlled discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing film is penetrated by the protrusion during opening operation, then the sealing film is opened and liquid flows out, but the user cannot control the timing of liquid discharge and the protrusion may obstruct the flow
Solution Approach 1:
The invention separates the opening function from the discharge function. The sealing film is opened by the protrusion penetrating it, but the actual liquid discharge is controlled separately by a discharge control member that can be independently operated. This segmentation allows users to first open the container and then control discharge timing, resolving the contradiction between ease of operation and reliability of liquid flow.
Solution Approach 2:
A discharge control member is introduced as an intermediary between the opening mechanism and the liquid discharge. This member includes a discharge hole that can be selectively opened or closed, acting as a mediator that decouples the opening operation from the discharge operation, thereby enabling controlled discharge timing and preventing protrusion obstruction.
2Ease of operation
If the protrusion penetrates the sealing film to open it, then the sealing is broken, but the protrusion tip closes the opening and hinders liquid outflow
Solution Approach 1:
The invention extracts the discharge control function from the opening mechanism. The protrusion is dedicated solely to opening the sealing film, while the discharge control member separately manages the discharge hole. This extraction prevents the protrusion tip from obstructing liquid flow, as the discharge hole's opening state is controlled independently by the discharge control member rather than being dependent on the protrusion position.
3Productivity
If the user raises pressure inside the bag body to open it, then the sealing film bulges and is penetrated, but the timing of liquid flow cannot be adjusted
Solution Approach 1:
The invention introduces a dynamic discharge control member that can change its state between closed and open. The discharge control member includes a discharge hole whose opening is controlled by a discharge control portion. This dynamic element allows the system to adapt between rapid opening (when discharge control is not engaged) and controlled discharge timing (when discharge control is engaged), resolving the contradiction between productivity and adaptability.

AI summary
A sealing container is designed to enable a user to adjust the timing of discharging the contents. The sealing container includes: a bag-shaped member for accommodating the contents therein, a sealing film for sealing the bag-shaped member, an opening means so configured that at least a part of which is movable toward the sealing film and is capable of opening the sealing film, an operation unit for performing an operation of moving the opening means, and a discharge means configured to be capable of discharging the contents from the bag-shaped member at a timing different from a timing at which the opening means penetrates the sealing film by operating the operation unit. It is possible for the user to perform only the operation of opening the sealing film by operating the operation unit, so that the user is able to arbitrarily adjust the timing at which the content is discharged from the bag-shaped member of the sealing container.
