A resealable closure for beverage containers uses initial physical interference to initiate a seal between a sealing flap and a dispensing port in a lid of the resealable closure. Once the initial seal is achieved, a pressure differential develops, resulting in additional force tending to bias the sealing flap toward the dispensing port. The sealing flap is actuated by an external drive means, that can also be a dust cover to prevent debris from contaminating any surfaces that may come into contact with the contents of the beverage container. There is a slack between initial movement of the external drive means and initial movement of the sealing flap, during which the pressure differential is preferably equalized through the unsealing of a vent hole in the resealable closure.

The apparatus of claim 10, which includes a plurality of support arms mounted on the first-mentioned framework for retraction and extension to both sides of the framework. 12. The apparatus of claim 1, wherein the trailer frame support arms mounted on said framework are disposed at longitudinally spaced positions for movement between a retracted position adjacent the framework and an extended position projecting laterally outwardly from the framework for supporting a trailer frame, to allow extension of the retracted support arms sequentially from the rear end toward the front end of the framework to allow sequential loading of the framework from the rear end toward the front end. 13. The apparatus of claim 12, which includes a plurality of support arms mounted on the framework for retraction and extension to both sides of the framework. 14. The apparatus of claim 1, wherein a support is secured to an end portion of a longitudinal member and projects upwardly therefrom. 15. The apparatus of claim 1, wherein said base has a plurality of substantially flat horizontally disposed ground-engaging feet members secured to its underside to distribute the weight of the apparatus and trailer frames on the underlying support surface. 16. Portable apparatus for storing multiple elongate trailer frames in a generally up-ended orientation, the apparatus comprising a first elongated framework having front and rear ends with a plurality of trailer frame support arms mounted on the framework for supporting a plurality of trailer frames in up-ended orientation, a second elongated framework having front and rear ends with a plurality of trailer frame support arms mounted on the framework for supporting a plurality of trailer frames in up-ended orientation, a base adapted to rest freely on the ground in a first location comprising first and second elongate rigid longitudinal members disposed substantially horizontally, parallel and spaced laterally from each other, and an elongate rigid connector member extending between said first and second members and secured adjacent one of its ends to said first member and secured adjacent its other end to said second member to form a substantially rigid U-shaped base structure, a plurality of elongate supports coupled to and extending upwardly from said base with said first and second frameworks coupled to and supported by the supports at an elevation spaced above said base, with the first framework being supported above the first member and the second framework being supported above the second member, and lifting means to which mechanical lifting mechanism may be attached to lift and transport the apparatus to a second location remote from said first location. 17. The apparatus of claim 16, wherein said lifting means comprises a lifting member having an aperture formed therein for receiving a connecting element on such lifting mechanism. 18. The apparatus of claim 16, wherein said first member, second member, and connector member comprise elongate tubular elements. 19. A method for providing temporary storage for multiple elongate trailer frames in a generally up-ended orientation, comprising the steps of providing a portable support apparatus having a base adapted to rest freely on the ground and an elongate framework supported on and at an elevated position above said base with a plurality of trailer frame support arms for supporting a plurality of trailer frames in an up-ended orientation, placing the portable support apparatus on the ground in a first location in which it is desired to support stored trailer frames, loading a plurality of trailer frames into said framework in a generally up-ended disposition, holding said trailer frames in the framework until needed, unloading said trailer frames from said framework, and moving said portable support apparatus by simple lift and transport to a second location in which it is desired to support stored trailer frames. 20. The method of claim 19, which further comprises the steps of providing lifting coupling means on the portable support apparatus, connecting a lifting device to the coupling means, and lifting the portable support apparatus from the ground to facilitate moving from said first location to said second location. 21. The method of claim 19, wherein said base includes hollow members and which further comprises the step of filling said hollow members with a flowable weight-increasing material. 22. The method of claim 19, wherein the base comprises rigid first and second elongate longitudinal members disposed substantially horizontal and spaced laterally from each other, and an elongate rigid connector member extending between said first and second members and rigidly secured thereto to form a base structure, and trailer frames are loaded into the framework between said first and second members. 23. The method of claim 19, wherein a second elongate framework having a plurality of trailer frame support arms is supported on and at an elevated position above said base, with said first-mentioned framework disposed above said first longitudinal member and said second framework being spaced laterally from said first-mentioned framework and disposed above said second longitudinal member with a space therebetween, and which further comprises the step of loading trailer frames into both said first-mentioned and second frameworks in generally up-ended disposition. 24. The method of claim 23, wherein each of said first-mentioned and second frameworks have a first set of trailer support arms extending outwardly therefrom in a direction away from the other of said frameworks and a second set of trailer support arms extending inwardly toward the other of said frameworks and into the space between said frameworks, and which further comprises the step of loading trailer frames into said first and second sets of support arms on said first and second frameworks.
