Safety Cap Spout Guarantee Seal Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety caps for pouch-type containers, particularly those for liquid food, face challenges in ensuring the accurate exposure of the broken guarantee seal for easy recognition and preventing airway blockage, due to design limitations that obscure the seal and hinder mass production.
Innovation Solution
The guarantee seal is coupled to the latching protrusion of the body, with the latching protrusion positioned on the guarantee seal and selectively latched to multiple latching grooves, allowing it to be accurately broken and exposed when the cap is opened, while preventing airway blockage through a vent hole design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the guarantee seal is positioned at the lower end of the inner cap, then the airway blockage problem is solved, but the guarantee seal cannot be formed directly under the inner cap and is obscured by the outer cap
Solution Approach 1:
The patent repositions the guarantee seal from a horizontal position at the lower end of the inner cap to a vertical position on the side surface of the inner cap. This dimensional change allows the seal to be both away from the airway opening and visible through the transparent outer cap, resolving the contradiction between safety and detectability.
Solution Approach 2:
The transparent outer cap serves as an intermediary that allows visual detection of the guarantee seal without compromising the safety function. The transparency of the outer cap enables users to observe the seal's integrity while the seal itself remains positioned to prevent airway blockage.
2Ease of manufacture
If the guarantee seal is spaced outward from the lower side of the cap, then the seal can be formed, but it is obscured by the outer cap and not easily exposed to the outside
Solution Approach 1:
The guarantee seal is repositioned from a spaced-outward horizontal arrangement to a vertical arrangement on the side surface of the inner cap. This dimensional reconfiguration maintains manufacturability while enabling visual exposure through the transparent outer cap.
Solution Approach 2:
The guarantee seal is designed with a color different from the inner cap material, creating visual contrast that enhances detectability. This color differentiation allows users to easily identify the seal's presence and integrity through the transparent outer cap.
3Manufacturing precision
If the latching protrusion is positioned on the guarantee seal, then accurate breakage can be achieved, but the guarantee seal must be precisely positioned which complicates manufacturing
Solution Approach 1:
The latching mechanism is segmented into distinct functional elements: the latching protrusion on the inner cap, the latching groove on the guarantee seal, and the inclined surface. This segmentation simplifies the overall design by dividing the latching function into manageable components that are easier to manufacture and assemble.
Solution Approach 2:
The latching groove is pre-formed on the guarantee seal during its manufacturing process, and the latching protrusion is pre-formed on the inner cap. This preliminary action ensures precise positioning and accurate breakage without requiring complex post-assembly adjustments or operations.

AI summary
The present invention relates to a spout for a pouch-type container in which a cap is coupled to a body fused to a pouch-type container body in a one-touch manner, and more particularly, to a spout which is applied to a safety cap and allows to accurately cut the guarantee seal and expose a cut-off state to an outside of an outer cap upon opening of the safety cap so as to achieve accurate opening and easy recognition, in which a guarantee seal is coupled to a latching protrusion of the body such that the latching protrusion is positioned on the guarantee seal and selectively latched to a plurality of latching grooves formed in the guarantee seal.
