Trash Bag Securing System Using Elastic Cord
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash bag securing systems are not securely fastened to trash receptacles, often leading to bag collapse under heavy items, and existing solutions are complex, costly, and impractical for home or office use.
Innovation Solution
A trash bag securing system that uses an elastic cord attached to the receptacle through strategically placed openings, allowing for customizable tension around the rim and secure anchoring without increasing bulk or cost, using a combination of holes, knots, and lacing patterns to hold the bag open along the entire rim.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional folding methods are used to secure trash bags, then the bag can be easily placed in the receptacle, but the bag collapses when heavy items are thrown in
Solution Approach 1:
The elastic cord is pre-attached to the receptacle rim through openings before the bag is placed. This preliminary securing action ensures the bag is held firmly from the start, preventing collapse when heavy items are added, while still allowing easy bag placement by simply folding the bag over the pre-positioned cord.
2Reliability
If complex securing devices with multiple components are used, then the bag can be securely fastened, but the device becomes expensive and impractical for home use
Solution Approach 1:
The invention extracts only the essential securing function from complex existing devices. By using a simple elastic cord attached through pre-formed openings in the receptacle, it eliminates unnecessary components like clamps, springs, loops, and hooks while maintaining effective bag securing through the fundamental elastic tension principle.
Solution Approach 2:
The invention replaces expensive, complex securing mechanisms with an inexpensive elastic cord that can be easily replaced. This disposable-like approach to the securing component (the cord) makes the system practical for home use, where cost and simplicity are paramount.
3Reliability
If existing securing devices are used, then some bag support is provided, but they do not secure the bag around 100% of the rim and lack adjustment capability
Solution Approach 1:
The receptacle rim is divided into multiple sections with openings distributed around the entire circumference. The elastic cord passes through these segmented openings, providing secure attachment points all around the rim (100% coverage) while allowing independent adjustment of tension at each opening to accommodate different bag sizes and weights.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively secures trash bags around 100% of the receptacle rim, preventing collapse and allowing for easy bag removal and replacement without losing or misplacing the securing device, while maintaining a simple and cost-effective design.
Implementation Method 1
an elastic cord is attached to the trash receptacle through the at least one opening, wherein the elastic cord is sized to fit around the outer surface of the sidewall

AI summary
A trash bag securing system having a plastic liner; the plastic liner inserted into the trash receptacle and placed over the at least one sidewall; a single elastic cord having a first end and a second end and which culminates in at least one knot. The at least one knot anchors the elastic cord to the receptacle. The at least one knot is a stopper at either the first end or the second end of the elastic cord and positioned on the outer surface of the least one sidewall. The elastic cord is inserted into the at least one opening and sized and positioned to fit around the outer rim of the outer surface of the at least one sidewall and over the plastic liner such to secure the plastic liner to the receptacle. The elastic cord may also be further configured to act as a handle.
