Twist-tie dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing twist-tie dispensers lack efficient and sanitary methods for refilling or replacing twist-ties, leading to concerns about spillage and hygiene, especially in environments like grocery stores where quick and cost-effective solutions are necessary.
Innovation Solution
A disposable twist-tie dispenser with a base and integral twist-tie cluster that can be easily mounted and removed from a fixture using hook-like extensions and a flexible latching mechanism, allowing for simple disposal and replacement, reducing the need for refilling and enhancing hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If twist-ties are dispensed from a reusable dispenser requiring refilling, then the initial investment cost is higher, but ongoing refilling operations are complex and potentially unsanitary
Solution Approach 1:
The patent implements a disposable dispenser design where the entire dispenser unit (base with twist-tie cluster) is discarded after use and replaced with a new unit. This eliminates the complex refilling operation entirely, as users simply remove the spent dispenser and attach a new one to the fixture. The disposable approach trades the higher initial investment of reusable dispensers for operational simplicity and sanitary conditions.
2Loss of substance
If twist-ties are dispensed using a reusable dispenser, then resource utilization is improved, but spillage risk and sanitary concerns increase
Solution Approach 1:
The disposable dispenser design with integrated twist-tie cluster eliminates spillage and sanitary contamination risks by sealing the twist-ties within the dispenser unit until dispensing. The sealed cluster prevents exposure to contaminants during storage and handling, while the controlled dispensing mechanism prevents spillage. After use, the entire unit is discarded, ensuring no cross-contamination between uses.
3Ease of operation
If a disposable dispenser with integral twist-tie cluster is used, then refilling complexity is eliminated, but the frequency of replacement increases
Solution Approach 1:
The dispenser is pre-loaded with a complete twist-tie cluster during manufacturing, eliminating the need for on-site refilling operations. The preliminary action of pre-assembling the twist-tie cluster within the sealed dispenser unit allows for rapid replacement - users simply detach the spent unit and attach a pre-loaded new unit, minimizing downtime and replacement frequency impact.
4Ease of operation
If hook-like extensions are used for mounting, then attachment to fixture is simplified, but structural complexity of base increases
Solution Approach 1:
The mounting function is segmented into separate components: hook-like extensions protruding from the base and corresponding receptacles on the fixture. This segmentation allows the base to have a simple overall structure while incorporating specific mounting features that simplify attachment. The hooks are discrete elements that can be easily molded or attached to the base, providing simple mounting without requiring complex structural modifications to the entire dispenser.

Function Achieved in This Case
The solution provides a sanitary and cost-effective method for managing twist-ties by allowing for easy disposal and replacement of the entire dispenser unit, improving hygiene and reducing waste, while maintaining a clean appearance and matching advertising themes.
Implementation Method 1
a flexible portion of the rear wall that is configured to elastically deflect through a cut-out provided on the rear wall
Implementation Method 2
the latching structure also defined at least in part by a flexible portion of the rear wall that is configured to elastically deflect through a cut-out provided on the rear wall... the flexible portion also defining a lower stop surface that opposes the upper stop surface of the first hook-like extension when the rod-like mounting structure is within the pocket

AI summary
A twist-tie dispenser comprises a twist-tie cluster and a base. The base includes a top portion, a rear wall extending downward from the top portion, and an open front. A latching structure for removably mounting the base to a fixture is defined at least in part by a first hook-like extension protruding from the rear wall of the base, the first hook-like extension defining a pocket formed by an upper stop surface and a vertical retention surface, the latching structure also defined at least in part by a flexible portion of the rear wall that is configured to elastically deflect through a cut-out provided on the rear wall in a direction from the rear wall toward the open front when a rod-like mounting structure of the fixture is inserted into the pocket of the first hook-like extension, the flexible portion also defining a lower stop surface that opposes the upper stop surface of the first hook-like extension when the rod-like mounting structure is within the pocket and is captured between the lower stop surface and the upper stop surface.
