The invention is directed to a sealing sheet for use to close a container-defining sheet having a top surface comprising a given number of spaced apart cavities embossed therein, each of the cavities being upwardly opened and thus defining a container that is surrounded by a flange that is part of the top surface of the container-defining sheet. A mold comprises first and second molded members having inner spaces passing through in the axial direction and an axial member detachably inserted through the individual inner spaces of the individual molded members. In addition, the dropper of eye drops has a simple design in structure and is convenient for use. A) The improved tire consists of an elastomeric material coating that is applied to the beads of the tire to obtain an elastic property. The balance between a floating force and a load pressure, acting on a slider, may be maintained, and consequently, and the slider may move in a rolling direction and a pitching direction. The bearing further includes a diffusion barrier disposed between the sleeve and the stator.
