Abstract
A retainer with a closure mechanism not removable from the retainer is bonded to each of the air inlet openings of an inflatable convective thermal blanket. The bottom surface of the retainer is bonded to the blanket so that its orifice is in alignment with the opening into the blanket. The closure may be a flexible layer or sheet that is adhesively attached to the top surface of the retainer. An end portion of the flexible layer away from the orifice of the retainer may be press or die cut into the retainer so that the flexible layer is non-removably attached to the retainer when the user peels the releasably secured portion of the flexible layer away from the retainer to expose the air inlet opening. The closure can also be an extension of the retainer that is hingedly connected to the retainer so as to be able to be moved pivotally to cover the retainer. The closure has a configuration that allows it to be releasably secured to the retainer when it covers the orifice opening of the retainer.
