Abstract: A one-piece clamp includes a unitary body having a bottom panel, end panels and top panels movably connected to the end panels and to each other. A pair of top cross-panels are end mounted on the top panels and are brought into co-planar, end-to-end orientation when the top panels are moved into end contact with the bottom panel. The body can be extrusion molded and cut to any desired length.

Abstract: A measuring and dispensing closure for dispensing a measured amount of material from a container. The closure has a wedge rotatably secured between a pair of discs one of which is attached to the container and each having defined therein a dispensing slot which is offset from the other dispensing slot. The wedge has a metering chamber which is alignable with the dispensing slots in the discs for dispensing a metered amount of material from the container, and a sealing surface alignable with the dispensing slot in the disc attached to the container for effecting an essentially air-tight seal of the container. The metering chamber is divided so that less than a full charge of material can be dispensed.
