A storage case for a flat circular Niger such as a compact disc includes a plastic box that has top and bottom walls and a front end which in open so that the flat circular maker may be inserted into the box between the top and bottom walls. A spring member inside the box adjacent its rear wall has one part that is fixedly secured to the box, and a movable part that when released can directly engage the peripheral edge of the flat circular member. The movable part of the spring member is normally stored in a retracted position behind a rib that extend inwardly from the top wall of the box. The top wall has a flexible portion behind the rib which is downardly depressible for releasing the movable part of the spring member so that it will then engage the compact disc and eject it from the open front end of the box.

Self-ejecting compact disc case

A shield for a hypodermic needle assembly includes a hollow plastic sleeve with an elongated main portion adapted to normally enclose the main portion of a needle, a slidable outer end portion which normally extends beyond the tip end of the needle, the elongated main portion of the hollow sleeve responding to an axial force on the outer end portion for expanding radially outwardly to retract the end portion of the sleeve and expose the needle tip end, a spaced pair of circumferential flanges formed on the elongated main portion of the sleeve, and a flexible collar encircling the sleeve and slidable over one of the flanges so as to occupy a position between the flanges and thereby prevent subsequent expansion of the main portion of the sleeve.

Flexing safety shield for hypodermic needles

A storage case for a flat circular member such as a compact disc includes a plastic box that has top and bottom walls and a front end which is open so that the flat circular member may be inserted into the box between the top and bottom walls. A spring member inside the box adjacent its rear wall has one part that is fixedly secured to the box, and a movable part that when released can directly engage the peripheral edge of the flat circular member. The movable part of the spring member is normally stored in a retracted position behind a rib that extends inwardly from the top wall of the box. The top wall has a flexible portion behind the rib which is downardly depressible for releasing the movable part of the spring member so that it will then engage the compact disc and eject it from the open front end of the box.

A shield for hypodermic needles is disclosed which is preferably of unitary construction and made of a plastic such as polypropylene. The shield is preferably cylindrical and is formed as a sleeve with a hollow bore for receiving the cannula of a hypodermic needle assembly. The shield is fixed at the hub of the needle assembly and can be either attached to the hub using a method such as heat or sonic sealing, or it can be manufactured with the hub as a unit. The sleeve has an upper axially rigid portion toward the tip end of the cannula, a lower axially rigid portion at the hub end, and at least two displaceable portions between the upper and lower rigid portions. Each of the displaceable portions are further subdivided into at least two subportions by introducing slits into the displaceable portions. The sleeve has hinging portions at the interfaces between the rigid portions and the displaceable portions, and a hinging portion at the interface between the displaceable portions.
