Core Pin Bag Dispenser With Orthogonal Apertures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag dispensers for supermarkets and grocery stores are inefficient in utilizing space, do not hold a large quantity of bags, require frequent servicing, and lack a visual indication for replacement, and are not easily fabricated from existing components.
Innovation Solution
A compact bag dispenser system that includes a support enclosure bin with integral channels for a rod, a retaining pin with orthogonal apertures for maintaining contact with the roll, and a snagging hook for easy bag dispensing, which can be mounted to various surfaces, including vertical and horizontal, with optional security links and stream guides for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If standardized bins with horizontal rods are used to hold large rolls of produce bags, then a large quantity of bags can be stored, but the dispensing mechanism becomes complex and requires frequent servicing
Solution Approach 1:
The invention divides the dispensing mechanism into separate functional components: a simple horizontal rod for bag storage and a distinct vertical dispensing assembly with a pouch. This segmentation allows the storage function to hold large quantities while the dispensing function remains simple and easy to service, resolving the contradiction between storage capacity and mechanism complexity.
Solution Approach 2:
The invention introduces a pouch as an intermediary element between the horizontal rod and the bag dispensing point. The pouch receives bags from the rod and guides them to the dispensing location, simplifying the overall mechanism while maintaining the ability to store large quantities of bags on the horizontal rod.
2Area of stationary object
If vertical surfaces are used for bag dispenser mounting, then space utilization is improved, but the dispenser must accommodate both vertical and horizontal mounting configurations
Solution Approach 1:
The invention designs the bin and rod assembly to be universally mountable on both vertical and horizontal surfaces. The horizontal rod can be installed in either orientation, and the dispensing mechanism adapts to the mounting surface, allowing the same device to utilize both vertical and horizontal spaces effectively without requiring different configurations.
3Device complexity
If a simple rod system is used for bag storage, then device complexity is reduced, but visual indication for bag replacement is lost
Solution Approach 1:
The invention incorporates a visual indicator mechanism that changes appearance based on bag availability. When bags are depleted, the system provides a visual signal (such as a color change or visible indicator) to alert staff that replacement is needed, maintaining the simplicity of the rod-based storage system while adding the necessary information feedback.

AI summary
A core pin bag dispenser includes a planar base sized and shaped to fit beneath a roll of film bags. First and second upwardly extending rods are mounted to the base. A retaining pin is sized and shaped to fit slidably within a hollow core of the bag roll. The pin has first and second orthogonal apertures located adjacent the first and second ends that are spaced apart by at least a width of the roll of film bags and are sized and shaped to fit slidably over the first and second upwardly extending rods. An upward pointing snagging hook is mounted adjacent a front edge of the base and is sized and shaped to engage either a chisel cut or a perforation in the bags. Two of the dispensers are mounted to an adapter designed to fit into the side channels of a bin mounted to a vertical surface.
