ABSTRACT:
A tension-exerted hoop for plastic and rubber articles comprises a tension-exerted (lock) hoop made up of a plurality of flexible wires wound into a hoop-shaped configuration wherein the flexible wires are respectively twined and bundled up via multiple thin filaments into identical-diameter wires each having a combining coarse surface defined by protruded and recessed sections at the outer periphery thereon. Therefore, when the tension-exerted hoop are housed inside plastic or rubber material of an air-filled container, the plastic or rubber material can penetrate into fissures formed among the thin filaments and securely bind with the coarse surfaces to create double layers of penetrative binding engagement thereby, increasing the binding area between the plastic or rubber material and the tension-exerted (lock) hoop so as to prevent the tension-exerted (lock) hoop from collapse and detachment during the repeated inflation and deflation operation of the air-filled plastic or rubber container thereof.
