Abstract: A closure for use with can-type containers, having an opening formed in one end by removing a portion of the container material. The closure has a vertical sidewall, forming a chamber within which a hermetically sealed elastic membrane is fastened, and an actuator plate resting within the vertical walls on the upper surface of the hermetically sealed membrane so that by downward movement of the actuator plate the membrane is forced to expand within the container opening, and with further downward movement of the actuator plate expands inside the container to provide a seal.

Abstract: This device is a rack for holding tobacco leaves while they are being cured. The rack includes two frame elements which, in their operative position, engagingly support a large bulk of individual tobacco leaves. A first frame element, in the shape of a square -- U, carries telescoping arms which are to be inserted in the guide means of a second frame element. Parallel to these arms and extending from the base of the U of the first frame element are elongated, sharpened, piercing rods which penetrate the tobacco leaves. Cooperative fastening means are found at each end of the base of the first frame element which cooperate with the latching means on the second element to maintain the frame in its operative position. The second frame element provides guide means and support for the first frame element. Also the second frame element has a latching means thereon.
