ABSTRACT:
The instant invention pertains to a flexible needle cover which surrounds a hypodermic needle on a syringe so that when the syringe is used the flexible needle cover retracts to expose the needle and after use the flexible needle cover returns back to its original shape covering the needle. The flexible needle cover of the instant invention is a bulb shaped elastomeric material that is capable of retracting during use with the application of slight pressure and returning to its original shape after the release of the pressure.
