Releasable closure
摘要:
A detachable closure includes separable burr-type elements which, at surfaces to be joined, have interlocking elements which mutually interlock during joining of the burr-type elements and hold the burr-type elements together. The interlocking elements are made of a material which carries out a deformation under the influence of heat, electromagnetic radiation, and/or a magnetic field.
