A soft-shelled ornament includes a transparent soft shell being clamped along an annular flange between a hold-down ring and a seat. The hold-down ring and the seat are tightly sealed into an integral unit by way of supersonic welding along two heat-sealing lines correspondingly provided at their contact surfaces. The hold-down ring and the seat are also provided at the contact surfaces radially inside said heat-sealing lines with two corresponding annular recesses for tightly receiving a leak-proof rubber ring therebetween. A flexible rubber plate is connected to the seat to bear against and close an inner end of a fluid inlet provided on the seat, so that a fluid is allowed to flow into but not out of the soft shell via the fluid inlet.
