  • Patent number: 4986097
    Abstract: A locking device for tank filler tubes is described, comprising a sleeve member for insertion in the filler tube to provide smooth walls, and an annular shaped locking collar that slides inside the sleeve and fastens through the sleeve to the inside wall of the filler tube. The locking collar does not have to be removed in order to fill the tank. Two disks, having off-center openings large enough for a filler hose nozzle, are arranged one above the other in the top of the locking collar so that the top disk can be rotated to allow the off-center openings to be aligned for a filler nozzle. A cylinder lock prevents rotation of the top disk when in the locked position. An alternative embodiment of the invention does not fit inside the tank filler tube, but rather is welded or joined to it. This alternative uses a padlock which prevents a cap from being rotated to a position which aligns openings in the device, allowing insertion of a filler hose nozzle.

  • Patent number: 4513875
    Abstract: Device for storing and dispensing a flowable substance that includes a container (20) having container apertures (50) and a multiply positionable lid (21) having lid apertures (49). With the lid (21) in the closed position, the lid (21) cannot be lifted from the container (20) and there is not access to the flowable substance. When the lid (21) is in the access position, the container and lid apertures align, allowing access to the flowable substance when an access seal (37) is altered. A third position, the remove position, allows removal of the lid (21) after the breaking of a lid removal indicator (51) so that tampering with the interior of the container (21) may be ascertained by, for example, the food supplier.

  • Patent number: 4489864
    Abstract: A tubular container is provided with a top end punch-out closure comprising a one-piece plastic cap and a rotor on the cap. A punch-out tab defined by a tearing web on the cap can be forced by finger pressure to hinge down from the cap to form a dispensing opening that is aligned with the major dispensing opening on the rotor at the fully open dispensing condition of the rotor. The side of the tab opening opposite the hinge has an arcuate edge that is substantially congruent with a corresponding arcuate edge of the major dispensing opening when the closure is fully open, with the radius of the latter being slightly smaller than the radius of the former to maintain an interference fit if the tab breaks off. The substantially congruent arcuate shapes allow exertion of downward compressive finger pressure at a location sufficiently close to the tearing web to indirectly apply tensile pressure with sufficient concentration to rupture the web.

  • Patent number: 4181246
    Abstract: A closure for a collapsible tube having a base portion mounted on the reinforced dispensing end of the tube. The base portion of the closure defines a bore communicating at one of its ends with the interior of the tube. The opposite end of the bore opens on the surface of a substantially spherical portion of the base member and serves as an outlet through which the tube contents are dispensed. This outlet is selectively opened and closed by a cap member fabricated from a semi-rigid material which defines a cavity which rotatably receives the spherical member therein. The tube contents are dispensed by rotating a port defined in the cap member into alignment with the base portion outlet and collapsing a portion of the tube wall. In one embodiment means are provided to assist in guiding the rotation of the cap member with respect to the spherical member for purposes of aligning the base portion opening and the cap member opening.
