Break-off Spout with Segmented Cover for Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing break-off spouts face issues with damage to weakened sections during assembly, transport, and storage, leading to loss of sealing performance, and are difficult to clean and pack efficiently.
Innovation Solution
A break-off spout design featuring a spout main body with a integrated break-off section and a cover consisting of two divided cover members that engage via hinge sections below the weakened area, preventing direct force application to the break-off section and allowing easy cleaning and packing by blocking a through-hole with deformation means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cover is integrated with the spout main body via the break-off section, then production and assembly are simplified, but force applied during assembly damages the weakened section and loses sealing performance
Solution Approach 1:
The cover is divided into a first cover member and a second cover member that are separate from each other, allowing them to be assembled without applying force to the break-off section. This segmentation enables independent positioning and attachment of each cover member to the spout main body, preventing damage to the weakened section while maintaining sealing performance.
2Object-affected harmful factors
If the cover is placed and secured onto the break-off section, then the spout main body is protected, but force applied during assembly damages the weakened section and loses sealing performance
Solution Approach 1:
The first and second cover members act as intermediaries that protect the spout main body without directly transmitting assembly force to the break-off section. By positioning these cover members on opposite sides and securing them independently, the design provides protection while avoiding force application to the weakened section, thus maintaining sealing performance.
3Object-affected harmful factors
If external force is applied to the cover during transport or storage, then the cover provides protection, but force is transmitted to the break-off section causing damage and loss of sealing performance
Solution Approach 1:
The segmented cover structure with first and second cover members positioned on opposite sides distributes and isolates external forces, preventing direct transmission to the break-off section. This segmentation creates a protective configuration that absorbs or redirects external forces away from the weakened section, maintaining sealing performance during transport and storage.
4Object-affected harmful factors
If the break-off section is closed off from the start, then hygiene is improved, but the spout is difficult to clean and contents cannot be sufficiently packed
Solution Approach 1:
The first and second cover members are preliminarily positioned to close the spout opening, providing hygiene protection during production and storage. The design allows these cover members to be easily removed or opened when cleaning or packing is required, thus maintaining both hygiene protection and operational ease through preliminary protective positioning that can be readily adjusted.

AI summary
The break-off spout of the present invention includes: a spout main body (110) having a break-off section (150) formed via a weakened section (121) such that an annular section (152) having a through-hole formed therein protrudes to the tip side; and a pair of left and right cover members (160) integrally formed with the spout main body (110) via hinge sections provided below the weakened section (121). The pair of left and right cover members (160) are formed in a shape such that, when the cover members are engaged with each other, the cover members cover a portion of the spout main body (110) above the hinge sections including the break-off section (150). An insertion port (164) through which deformation means that deforms the annular section (152) and blocks the through-hole can be inserted is provided in the cover members (160).
