  • Patent number: 6568045
    Abstract: A spring fastener for securing one or more sheets of material on another sheet of material having a V-shaped clip, which clip has two sides. Preferably, one of the sides has a wide angle bent, while the other side has one or more embosses and/or recesses. The fastener also comprises an elastic body extending from the vicinity of the top section of the V-shaped clip to at least one of the embosses. Examples of elastic bodies are foamed or un-foamed plastisol, polyurethane, silicone, thermoplastic elastomer, and a combination thereof. The substantially central part of the elastic body, between the first side and the second side of the V-shaped comprises a cavity with a closed cavity bottom, thus providing to the fastener easy insertion to an opening of a first rigid sheet, combined with unexpectedly improved sealing performance.
