Beverage container holders which typically include a single-cup beverage container holder, a dual-cup beverage container holder, a three-cup beverage container holder and a four-cup beverage container holder. The respective beverage container holders are each characterized by at least one container

Beverage container holders which typically include a single-cup beverage container holder, a dual-cup beverage container holder, a three-cup beverage container holder and a four-cup beverage container holder. The respective beverage container holders are each characterized by at least one container cup and a handle attached to the container cup, which handle is typically hollow and serrated or scalloped to facilitate non-rotatable nesting of the handles of two or more of the beverage container holders in either stored or functional configuration. The various configurations of the container cups on the handles facilitates selective positioning of the container cups of multiple nested beverage container holders, to enable an individual to carry a selected number of beverages using one hand at the nested handles. In another embodiment, a dual tray characterized by a pair of typically recessed and/or planar tray surfaces extending from a common serrated handle can be used alone to carry food, or in handle-nested combination with one or more of the beverage container holders for carrying both food and a drink or drinks using one hand.

The separator of claim 1 wherein an end portion of the bolt member is externally threaded and wherein the rotating member is a nut. 7. The separator of claim 6 wherein the other end of the bolt member is connected to the screen. 8. The separator of claim 1 wherein the tension of the screen creates a force that is opposite to the axial force exerted by the spring means so that, as the rotating member is rotated in the first direction, the bolt member moves relative to the rotating member to increase the force caused by the screen tension, and the rotating member moves relative to the bolt member to increase the force caused by the spring tension, and as the rotating member is rotated in the second direction, the bolt member moves relative to the rotating member to decrease the force caused by the screen tension, and the rotating member moves relative to the bolt member to decrease the force caused by the spring tension. 9. A method for tensioning a screen relative to a wall of a separator, the method comprising the steps of connecting a housing to the wall, mounting a bolt member for reciprocal translational movement relative to the housing, connecting one end of the bolt member to the screen, threadedly engaging a rotating member with the other end of the bolt member so that rotation of the rotating member causes relative translational movement between the rotating member and the bolt member, applying an axial force against the rotating member, rotating the rotating member in a first direction to cause corresponding relative translational movement between the rotating member and the bolt member to apply a tension to the screen, rotating the rotating member in a second direction to cause corresponding relative translational movement between the rotating member and the bolt member to release tension on the screen, and limiting the translational movement of one of the members in response to a predetermined tension on the screen. 10. The method of claim 9 further comprising the step of pivotally mounting a rail to the wall, connecting the rail to the screen and to the bolt member so that the translational movement of the bolt member pivots the rail and applies the tension to the screen. 11. The method of claim 10 wherein one end of the rail engages the inner surface of the wall and establishes a fulcrum for pivotal movement of the rail relative to the wall. 12. The method of claim 11 wherein an end portion of the bolt member is externally threaded and wherein the rotating member is a nut. 13. The method of claim 12 wherein the other end of the bolt member is connected to the screen. 14. The method of claim 9 wherein the tension of the screen creates a force that is opposite to the axial force exerted by the spring means so that, as the rotating member is rotated, the bolt member moves relative to the rotating member to increase the force caused by the screen tension, and the rotating member moves relative to the bolt member to increase the force caused by the spring tension. 15. A device for applying tension to a screen extending between at least two walls, the device comprising a housing disposed adjacent the wall, a bolt member connected to the screen and adapted for translational movement relative to the housing, a rotating member in threaded engagement with the bolt member for receiving torque, spring means for applying an axial force against the rotating member so that rotation of the rotating member in a first direction causes relative translational movement between the rotating member and the bolt member to apply a tension to the screen, and rotation of the rotating member in a second direction causes relative translational movement between the rotating member and the bolt member to release tension on the screen, and means for limiting the translational movement of one of the members in response to a predetermined tensio
