Flexible Wall Pouch Container With Concealed Child-Resistant Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nicotine pouch containers are not effectively child-resistant and are costly to produce.
Innovation Solution
A nicotine pouch container design featuring a body, lid, and flexible member that are produced as separate parts, allowing for cost-effective manufacturing through injection molding, with a snap-fit assembly and a flexible member that blocks the gripping surface until an inward force is applied, making it difficult for children to open but easy for adults.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional container design is used, then the container is easy to manufacture, but it is not child-resistant
Solution Approach 1:
The container is divided into separate components: a body portion and a lid portion that can be manufactured independently and then assembled. This segmentation allows each part to be optimized for manufacturing efficiency while enabling the assembly to provide child-resistant functionality through the interaction of multiple components.
Solution Approach 2:
The lid portion incorporates a flexible member that can dynamically change its configuration between a first state (blocking the gripping surface) and a second state (revealing the gripping surface). This dynamic behavior enables the container to be child-resistant when closed but accessible when the correct opening mechanism is applied.
2Reliability
If a child-resistant mechanism is added, then child-resistance is improved, but the device complexity increases
Solution Approach 1:
A flexible member is integrated into the lid portion to provide the child-resistant mechanism. This flexible component can be manufactured as a simple part and assembled onto the lid, adding child-resistant functionality without requiring a complex mechanical structure. The flexible member blocks the gripping surface in its first state and reveals it in its second state when inward force is applied.
3Ease of manufacture
If separate parts are assembled, then manufacturing cost is reduced, but assembly complexity increases
Solution Approach 1:
The container is segmented into a body portion and a lid portion that can be manufactured separately using cost-effective processes like injection molding. This segmentation reduces manufacturing costs by allowing standardized production of individual components while maintaining relatively simple assembly requirements.
Solution Approach 2:
The flexible member is combined with the lid portion in a single assembly step, where the flexible member is positioned and secured onto the lid. This merging of components simplifies the overall assembly process by reducing the number of separate steps required while maintaining the child-resistant functionality.

Function Achieved in This Case
The design provides a cost-effective, child-resistant nicotine pouch container that is easy for adults to open while preventing access by children, ensuring safe use and efficient production.
Implementation Method 1
The flexible member is configured to flex towards the side wall of the body when an inwardly directed force is applied to the flexible member

AI summary
A nicotine pouch container, use of the container and a method for manufacturing the same, which container comprises a body and a lid configured to engage the body. The body comprises a bottom wall and a sidewall. The lid comprises a top wall and a lid side wall with a gripping surface The nicotine pouch container further comprises a flexible member being sized and configured to be assembled on the outside of the side wall of the body and configured to flex towards the side wall of the body when an inwardly directed force is applied to the flexible member (14). The gripping surface of the lid side wall is blocked by the flexible member in a first state, and revealed in a second state in which the inwardly directed force is applied to the flexible member.
