Method for packaging twist ties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional twist tie dispensing devices do not effectively maintain a continuous image display when individual twist ties are removed, disrupting the visual presentation intended for users.
Innovation Solution
A stack of connected tie web sheets with an image that remains visible and unchanged upon removal of twist ties, utilizing repositionable adhesive and perforations to ensure the image's overlay registration across sheets, including a backer card and container configurations that maintain image continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual twist ties are removed from the dispensing device, then the dispensing function is achieved, but the image display is disrupted and visual continuity is lost
Solution Approach 1:
The patent divides the image display into multiple segments across different tie web sheets, with each sheet containing a portion of the overall image. When sheets are removed during dispensing, the segmented images on the backer card maintain the complete visual display. This segmentation allows individual sheets to be removed for dispensing while the remaining sheets and backer card continue to display the full image.
Solution Approach 2:
The backer card serves as an intermediary element that carries image portions and maintains visual continuity when twist tie sheets are removed. The backer card acts as a mediator between the removed sheets and the remaining display, ensuring that the overall image remains intact and continuous even as individual components are dispensed.
2Quantity of substance
If multiple tie web sheets are stacked together, then bulk dispensing is enabled, but the image alignment and visual consistency across sheets becomes difficult to maintain
Solution Approach 1:
The patent combines multiple tie web sheets with images onto a single backer card, creating an integrated assembly where all sheets are held in precise alignment. This merging of multiple sheets with the backer card ensures that images across all sheets are properly aligned and registered, maintaining visual consistency throughout the bulk dispensing package.
Solution Approach 2:
The images on all tie web sheets and the backer card are pre-aligned and registered during manufacturing before the sheets are stacked. This preliminary alignment action ensures that when multiple sheets are combined in the stack, the images automatically maintain proper registration and visual consistency without requiring complex alignment mechanisms during dispensing.
3Reliability
If twist ties are securely attached to the stack, then dispensing reliability is improved, but removal becomes difficult and may damage the image
Solution Approach 1:
The patent applies different attachment characteristics to different regions of the twist tie sheets. The proximal ends of the twist ties are securely attached to the backer card to maintain reliability, while the distal ends are designed with perforations that facilitate easy user removal. This local differentiation of attachment quality allows both secure holding and easy dispensing.
Solution Approach 2:
The twist tie sheets are divided into distinct regions with different functions: the proximal attachment region provides secure holding to the backer card, while the distal region includes perforations for easy user removal. This segmentation of the attachment system allows the structure to provide both strong attachment and easy separation at different locations.

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.
