Abstract: An elongate flexible tubular sheath has a longitudinal slit therethrough from end to end. The sheath is placed over a conduit, having an outside diameter not smaller than the inside diameter of the sheath. Subsequently, the sheath is tightened about the conduit and the edges of the slit forced together in response to helical twisting of the sheath. Means are provided for retaining the sheath in the helically twisted position.

Abstract: The lunch box comprises a generally square base container and a correspondingly shaped cover each being integrally formed from the same polymeric material. The base container has an integral handle extending forwardly from one side and integrally formed hinge tabs extending rearwardly from an opposite side. The cover, in turn, has integrally formed hinge blocks with slots for receiving the hinge tabs. The arrangement is such that in open position, the top of the cover is coplanar with the bottom of the base container so that both cover and container can engage a flat surface and function as serving trays for contents in the box. In a second position, wherein the box is closed, the cover is simply swung by flexing of the hinge tabs over the top of the container to close the upper opening. The container and cover openings include cooperating lip and step structures providing an hermetic seal and also frictionally holding the cover in place on the container.

Abstract: A planter having a supporting tray and potting vessel arrangement wherein the vessel is supported with its bottom portion within a tray compartment and in juxtaposition with the compartment walls. The vessel tray combination further provides for the access of air to the compartment and for its direction up and around vegetation foliage within the vessel.

Abstract: A pair of opposed arms include rearward portions which extend tangentially from the cylindrical sidewall of a rigid connecting structure. The rearward portions diverge to substantially parallel intermediate portions having forward portions extending therefrom. A jaw having a face terminating in a nose is carried by each forward portion. Each arm increases in width from the connecting structure to a finger purchase area of the intermediate portion adjacent the forward portion. A rib, integral with each arm, extends from the jaw through the sidewall of the connecting structure and extends therefrom throughout the extent of the sidewall bounded by the arms. In response to compressive force applied to the purchase areas, the arms bend arcuately until the noses of the jaws abut. Continued force causes the jaws to meet in face-to-face relationship.
