Pouring Spout With Removable Closing Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refill containers face issues with the separation of the weak part in the flat plate of the spout, leading to broken pieces and potential clogging, and require multiple refilling steps which can cause quality changes in remaining contents.
Innovation Solution
A pouring spout design featuring a tubular pouring part with a separate closing member and an energizing body, allowing smooth opening and closing without producing broken pieces, and an attachment mechanism for manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a weak part is formed in the flat plate to enable separation, then the spout can be opened for refilling, but broken pieces are produced during separation
Solution Approach 1:
The invention divides the spout into separate components: a removable cap portion and a body portion with a closing member. The cap can be detached without forcing separation, eliminating broken pieces while maintaining ease of opening for refilling operations.
Solution Approach 2:
The closing member is extracted as a separate component that can be independently removed from the spout body. This allows the spout to be opened without compromising the structural integrity of the remaining components, preventing broken pieces during the opening process.
2Reliability
If the spout is re-closed after partial refilling to prevent quality changes, then contents quality is maintained, but the closing mechanism complexity increases
Solution Approach 1:
The closing member is designed to be manually operable by the user without requiring additional tools or complex mechanisms. The simple cap-and-body structure allows users to easily open and close the spout themselves, maintaining contents quality through multiple refilling operations without increasing device complexity.
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
Enables seamless transfer of contents without breaking pieces and prevents quality changes by maintaining air-tightness during multiple refilling steps, ensuring the contents remain fresh.
Implementation Method 1
a spring member (55) attached to the holding body (51), the spring member (55) coupling the holding body (51) and the closing member (20), wherein the spring member (55) applies an elastic force to the closing member (20) in a direction toward the inflow port (10d)

AI summary
A pouring spout of a container includes a spout main body, a closing member, and an energizing body. The spout main body includes a tubular pouring part and an attached part. The tubular pouring part includes an inflow port through which contents are flown in from a container main body and an outflow port. The attached part is configured to attach the inflow port to the container main body. The closing member is configured as a separate body from the tubular pouring part and fitted onto an inner circumferential surface of the tubular pouring part to close the inflow port. The energizing body presses the closing member from the container main body toward the inflow port. The closing member is capable of being removed from the inner circumferential surface of the tubular pouring part by an external force applied against the pressing by the energizing body.
