Bag in Box Spout Retention via Diagonal Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag in box packaging systems often make it difficult for users to couple the tap to the outer box, leading to accessibility issues and the risk of the tap becoming dislodged during use, due to the tap's orientation and the limited opening size for securing it.
Innovation Solution
The design incorporates an inner spout retaining member with a diagonally spanning panel and a spout receiving slot, allowing the spout to be securely positioned and locked within a triangular cross-sectional configuration, with a frangible portion for easy access and a bottom encapsulating panel for additional locking, facilitating easier dispensing and reducing the risk of dislodgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tap is inserted into the outer box through a small opening for securing, then the tap can be coupled to the box, but the user finds it difficult to reach and couple the tap due to the limited opening size and difficult orientation
Solution Approach 1:
The outer box is divided into two functional parts: a small securing opening for attaching the tap to the box structure, and a separate large access opening for user interaction. This segmentation allows the tap to be securely mounted through the small opening while remaining accessible through the large opening, resolving the contradiction between secure coupling and ease of operation.
Solution Approach 2:
A panel is introduced as an intermediary component that spans the large opening and provides a stable surface for user interaction. This panel acts as a mediator between the user and the tap, allowing easy access and operation without requiring the user to reach through the small securing opening, thus improving ease of operation while maintaining secure coupling.
2Reliability
If the opening in the box is used to secure the tap to the outer box, then the tap can be attached, but the opening is too small to allow for a user to delve deeply into the outer box
Solution Approach 1:
The box structure is segmented into two distinct openings with different functions: a small opening optimized for secure tap attachment and a large opening optimized for user access. This functional segmentation allows the securing opening to remain small for reliability while the access opening provides deep accessibility, eliminating the need for the single opening to serve both purposes.
Solution Approach 2:
The access function is extracted from the securing opening. The large opening is specifically designed for user access and panel interaction, while the small opening is dedicated solely to tap securing. This extraction of functions allows each opening to be optimized for its specific purpose, maintaining security while improving accessibility.
3Reliability
If the tap is inserted in a difficult orientation to fit into the outer box, then the tap can be secured, but it becomes difficult to reach and use
Solution Approach 1:
The orientation problem is resolved by separating the securing function from the access function. The tap is secured in its proper orientation through the small opening, while the large opening with its panel provides unobstructed access for user interaction. This extraction of functions allows the tap to be secured in the correct orientation without compromising reachability.
Solution Approach 2:
The panel spanning the large opening serves as an intermediary that provides a stable access point for user interaction. It allows users to reach and operate the tap without needing to access the tap directly through the small securing opening, thereby maintaining both secure retention and ease of operation.

AI summary
The bag in box packaging comprising an inner bag, an outer carton and an inner spout retaining member. The inner bag defines a cavity with a spout coupled thereto. The outer carton includes a front wall and a first sidewall positioned adjacent the front wall, both extending from a bottom wall to a top wall. The inner spout retaining member including a first panel spanning diagonally from the first sidewall to the front wall obliquely relative to each wall and spaced apart from a side edge joining the front wall to the first sidewall, to define a triangular cross-sectional configuration. The first panel includes a spout retaining slot extending thereinto. The spout extends into the spout receiving slot so as to capture the spout within the cross-sectional configuration and directed toward the side edge. The inner bag is positioned on the opposite side of the first panel.
