  • Patent number: 5318364
    Abstract: A closure system for a plastic security bag comprises an access opening of the security bag formed by the displaced top edges of the front and rear panels. An adhesive laden carrier film regulates access thereto. The film has an internal line of serration and is affixed to the bag below the top edge of the front panel. A band of temperature-sensitive "hot melt" is supplied therealong. Upon removal of the releasable liner the carrier film is positioned such that the hot melt contacts the rear panel of the bag with the edges of the carrier film aligned with the edges of the rear panel to preclude purchase of the edges. The bag bears ink indicia which deteriorates upon chemical substances being sprayed thereon in an attempt to fracture the adhesive bond. The flush edges of the bag and/or the water-based indicia preclude an undetected, undesirable access to the bag. The bag has scalloped marginal edges which are separable if one attempts to enter the bag at the marginal edges.

  • Patent number: 5108194
    Abstract: A closure system for a plactic security bag comprises an access opening with an adhesive laden cellophane carrier film regulating access thereto. The film is affixed to the bag below the lower edge of the access opening and has a band of "hot melt" therealong. Upon removal of the releasable liner the carrier film is positioned such that the "hot melt" spans the access opening and closes the same. Lacquer coating at the ends of the opening preclude undesirable sticking of the releasable liner to the security bag. The ends of the access opening are "heat sealed" and cooperate with the adhesive to preclude leakage of liquid through the closed opening. Entry of the bag is accomplished by tearing the carrier film and/or bag proper which is evident to an observer.

  • Patent number: 4479273
    Abstract: A locking device for a toilet seat lid comprises a rotatable lever arm having a downwardly extending flange mounted adjacent the free end thereof. The lever arm is rotatably mounted on a mounting plate with the latter being fastened to the toilet bowl to the rear of the toilet seat by means of the conventional seat-fastening bolts. The flange cooperates with the free end of the lever arm to present a jaw-like structure for receiving a portion of the rear of the closed lid therein. Upon movement of the closed lid towards an open position the lid engages the jaw-like structure in a manner which opposes movement of the lid towards a fully open position. The lever arm is user-rotatable to a position free of the closed lid to allow opening of the lid and access to the toilet bowl. A spring bias on the lever arm returns the lever arm to the original lid-receiving position upon the lid being returned to its closed position.
