Abstract
The present invention provides a sealing closure made of flexible magnetic strips with a non-uniform thickness, which provide an improved interlocked seal in addition to a magnetic seal. The sealing closure has strips with at least one guide that aligns automatically with another strip when the two strips are brought together to create a more secure sealing closure.
Claims20
A magnetic sealing closure, comprising:
- a first flexible strip, having a first side and a second side, with a plurality of cavities having a plurality of magnetic elements therein, the second side of the first flexible strip having a raised portion;
- a second flexible strip, having a first side and a second side, with a plurality of cavities having a plurality of magnetic elements therein;
- a third flexible strip, having first side and a second side, with a plurality of cavities having a plurality of magnetic elements therein, the second side of the third flexible strip having a recessed portion corresponding to the raised portion of the second side of the first flexible strip;
- a first membrane coupled to said first side of said first strip, such that said plurality of magnetic elements of said first strip are flush mounted and embedded within said plurality of cavities between said first strip and said first membrane, said first membrane further coupled to said first side of said third strip, such that said plurality of magnetic elements of said third strip are flush mounted and embedded within said plurality of cavities between said third strip and said first membrane;
- and
- a second membrane coupled to said first side of said second strip, such that said plurality of magnetic elements of said second strip are flush mounted and embedded within said plurality of cavities between said second strip and said second membrane;
- wherein said first and said second strips provide a first seal when said first and said second strips are brought together from said first sides of said first and said second strips and magnetic elements of said first and said second strips magnetically attract each other,
- wherein said first and said third strips provide a second seal when said first, said second, and said third strips are subsequently brought together from said second sides of said first and said third strips and magnetic elements of said first and said third strips magnetically attract each other.
