  • Patent number: 5215188
    Abstract: A security package having a slidable locking structure to retain a CD, cassette or the like in the security package. The slidable locking structure has a stationary surface which contains a T-shaped protrusions each having a lever arm. A slide plate contains recesses for receiving each end of the lever arm, apertures adjacent to these recesses and a lip along an edge. The security package is locked when the slide plate is slid to engage the lever arms into the recesses allowing the lip to extend over the holding structure to retain the CD, cassette or the like. A key which mates with the apertures is used to apply a simultaneous uniform force to release the lever arms from the recesses.

  • Patent number: 5038677
    Abstract: A can crusher for compacting cans, such as aluminum soft drink cans, into a substantially flat configuration for storage, recycling or disposal. The can crusher includes a base with opposing flanges and a handle which rotates about the flanges. The handle includes an extending crimping member which compresses the center of the can downwardly, and also forces the ends of the can inwardly. The handle also includes a flat surface which then flattens and rotates the ends of the can towards a mid-portion of the can into a substantially flat configuration. The first action of the extending crimping member against the can and the second action of the flat surface against the can crush the can into a substantially flat can which is environmentally and ecologically useful in recycling processes. The crushed can consumes less space in recycling operations or disposal, and environmentally and ecologically presents itself in a more pleasing manner for recycling or disposal.
