Foldable Bag Collar With Locking Notch for Fast Twisted Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a continuing need for new ways to close garbage bags, particularly diaper pails, beyond cinching straps or tying knots, to ensure effective sealing when the bag is full.
Innovation Solution
A disposable bag with a foldable collar and a locking notch that allows the bag to be twisted and secured, featuring a foldable collar that collapses onto itself to maintain a closed configuration, using a locking notch to keep the neck of the bag in a twisted state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cinching straps or tying knots are used to close the bag, then the bag can be sealed, but the operation becomes time-consuming and complex
Solution Approach 1:
The collar is pre-formed with a specific geometry that includes a receiving structure designed to automatically engage with the twisted neck. This preliminary configuration eliminates the need for complex tying operations during bag closure, as the structure is already prepared to receive and secure the twisted neck in its intended position.
Solution Approach 2:
The collar's receiving structure is designed to self-engage with the twisted neck through simple manipulation. The geometry of the receiving structure allows it to automatically capture and hold the twisted neck without requiring additional fastening elements or complex user actions, making the sealing process self-service and time-efficient.
2Reliability
If traditional closing methods are used, then the bag can be sealed, but the ease of operation is reduced
Solution Approach 1:
The collar is pre-formed with a specific geometry that includes a receiving structure designed to automatically engage with the twisted neck. This preliminary configuration eliminates the need for complex tying operations during bag closure, as the structure is already prepared to receive and secure the twisted neck in its intended position.
Solution Approach 2:
The collar's receiving structure is designed to self-engage with the twisted neck through simple manipulation. The geometry of the receiving structure allows it to automatically capture and hold the twisted neck without requiring additional fastening elements or complex user actions, making the sealing process self-service and time-efficient.
3Stability of the object's composition
If the collar is rigid to maintain shape, then structural stability is improved, but the collar cannot collapse onto itself for sealing
Solution Approach 1:
The collar is designed with dynamic characteristics that allow it to transition between different states. It maintains its expanded shape and structural stability during normal use, but can be easily collapsed onto itself when sealing is required. This dynamic behavior enables the collar to provide both structural support and ease of operation for sealing.
Solution Approach 2:
The collar is constructed from flexible material that allows it to collapse onto itself while maintaining its structural integrity. The flexible nature of the material enables the collar to be compressed and folded without damage, yet it retains its shape and stability when in the expanded, open state for normal bag usage.

AI summary
A bag for holding trash, diaper, and any item that needs to be contained. The bag can have an enclosure body and a mouth opening where the opening is lined with a foldable frame. The foldable frame can fold out to keep the mouth opening in an open configuration, and can collapse upon itself to keep the mouth opening in a closed configuration. The foldable frame can optionally have a locking notch, a finger, or both, all of which can be used to attach to some part of the enclosure body thereby keeping the neck of the bag twisted closed. The bag can optionally have attachment points such as apertures, sleeves, strips, and loops for securing to the locking notch. In some embodiments, the collar need not be foldable.
