Twist Tie Dispenser Stack Design for Continuous Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional twist tie dispensing devices do not effectively maintain a continuous image display as twist ties are removed, leading to a disrupted user experience and inefficient packaging.
Innovation Solution
A stack of connected tie web sheets with an image that remains visible and unchanged during twist tie removal, utilizing repositionable adhesive and perforations to ensure the image's overlay registration across multiple sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple tie web sheets are stacked together for dispensing, then the quantity of twist ties available is increased, but the image display becomes disrupted and distorted as ties are removed
Solution Approach 1:
The patent transitions from a two-dimensional single-sheet display to a three-dimensional stacked configuration of multiple tie web sheets. By arranging sheets in layers with offset positioning, the invention creates a volumetric structure that maintains continuous image visibility from the front perspective while accommodating multiple rows of twist ties for increased quantity dispensing.
Solution Approach 2:
The invention divides the image display area across multiple separate tie web sheets, where each sheet contains a portion of the overall image pattern. The sheets are stacked and offset so that their combined visual appearance creates a continuous, undistorted image from the user's perspective, while each individual sheet can be independently depleted and removed.
2Ease of operation
If twist ties are removed from the stack for dispensing, then the usability and accessibility are improved, but the structural integrity and image alignment of the remaining sheets deteriorate
Solution Approach 1:
The invention extracts individual twist ties from the stacked sheets through perforated edges, allowing users to remove and use ties without disturbing the stacked configuration of remaining sheets. The perforated design enables clean separation of individual ties while maintaining the structural integrity and alignment of the multi-sheet stack.
3Device complexity
If conventional dispensing devices are used, then the device complexity is low, but the user experience and visual display quality are poor
Solution Approach 1:
The invention merges multiple tie web sheets into a single stacked assembly that functions as one integrated dispensing unit. The sheets are bound together with spacers that maintain precise spacing and alignment, creating a unified structure that delivers high-quality continuous image display while retaining the simplicity of a single dispensing device format.

AI summary
An apparatus (100, 200, 400, 500, 600) includes a stack (110, 310) having a plurality of connected tie web sheets (106, 306) and an image (114) disposed on each of the tie web sheets (106, 306), wherein the image (114) is the same on each tie web sheet (106, 306) and is disposed in overlay registration from sheet (106, 306) to sheet (106, 306). Each tie web sheet (106, 306) includes a plurality of twist ties (104, 304), each twist tie (104, 304) having a proximal end (118) and a distal end (120), each twist tie (104, 304) being removably attached to the stack (110, 310) at its proximal end (118). A method of dispensing a plurality of twist ties (104, 304) includes mounting a stack (110, 310) within reach of a user and displaying an image (114) disposed on each of the tie web sheets (106, 306). Removal of a twist tie (104, 304) of the plurality of twist ties (104, 304) of the stack (110, 310) does not alter the image (114) viewable by the user.
