contexte
"the needle cover includes the needle-covering portion and a snap clip portion . The snap clip portion includes a pair of cantilevered snap clip wings . Each of the snap clip wings is elastically deformable and has a sloped face, such that as the snap clip portion is inserted into the eyelet opening , the sloped faces engage the eyelet and the contact therebetween progressively deforms the snap clip wings ."

"After trailing edges of the sloped faces pass through the eyelet opening , the snap clip wings substantially return to their respective undeformed positions, thereby locking the snap clip portion in the eyelet , and retaining the release liner between the snap clip portion and the flange ."
