Abstract: A container closure assembly comprising a container having a finish and external threads and a cup-like cap having a top and a depending circumferentially extending skirt having second internal threads engagable with the container threads. Detents are providing on one of said threads to normally prevent rotation of the cap in a direction to remove it from the container. First and second interengaging members are formed integrally with the cap and container. One of the interengaging members is flexible to bias the cap in an upward direction to maintain the threads in engagement when the cap is seated on the container. Displacement of the cap downwardly against the normal bias of the interengaging means displaces the cap and container threads to disengage the detents to permit rotation of the cap in a direction to remove it from the container.

Abstract: A closure assembly for a container including an internally-threaded annular flange, an externally-threaded closure plug that is received by the annular flange, and an annular gasket positioned between the annular flange and the closure plug for establishing a sealed interface. The container includes a container end panel that is formed over and around a portion of the annular flange and provides an inner axial wall that is positioned between the annular flange and the annular gasket. The clearance between the closing plug and the inner axial wall relative to the size of the annular gasket determines the degree of radial compression of the annular gasket as the plug is threaded into the flange. A radial lip of the plug is designed to contact an upper surface of the container end panel that is formed over the flange as a visual indication when the required tightening torque of the plug within the flange has been reached.

Abstract: The invention provides a straw and beverage container combination wherein the straw has retention means such as a convoluted portion adjacent one end that resists removal of the straw from the central aperture of the container lid when a lid is attached to the container. The means also serve to maintain the straw inside the container in an upright position.

Abstract: This invention concerns a valve for an underpressure-activated outflow mechanism for a drinking receptacle (2). The valve includes a valve head (34) and a valve seat (44), in which the valve seat (44) is arranged in force-transmitting connection with a membrane (1), whereas the valve head (34) is fixed to the remaining structure via at least one stay (36).

Abstract: A cylinder barrel (1) for housing a piston comprises a sheet metal liner (2) and a reinforcing structure (10) located outside the sheet metal liner (2). The reinforcing structure (10) comprises a glass-fiber-reinforcing layer (12) and a carbon-fiber-reinforcing layer (13). The glass-fiber-reinforcing layer (12) comprises a plain cloth (20) made of glass fiber covering the sheet metal liner (2). The carbon-fiber-reinforcing layer (13) comprises a carbon fiber string (31) wound around the outer circumference of the glass-fiber-reinforcing layer (12) along a spiral path. According to the this construction, the reinforcing structure (10) has a high flexibility which is required for preventing cracks in the reinforcing structure (10) while maintaining a high rigidity of the entire cylinder barrel (1).

Abstract: A universal lid for industrial or commercial large size solid waste containers, has a ribbed single layer central portion and a peripheral edge having a hollow double wall boxed configuration. The boxed perimeter may have a predetermined height such as approximately one inch, and the lid is provided with hinge lugs having a vertical extent substantially more but not more than twice than said predetermined height. In addition, the lids have substantial symmetry so that the lids may be stacked and nested with alternate lids oriented in opposite front-to-back directions. With this type of lid, the advantages of both single layer and double layer lid constructions may be realized.

Abstract: The present invention relates to an oil storage tank equipped with a floating bed type inner floating roof. The oil storage tank structure has a tank body and an inner floating roof which lies on the liquid surface inside the tank. The inner floating roof includes filling bags and a resilient sealing tube. The filling bags, separated by isolation sheets, are filled with floating plates. The resilient sealing tube is disposed around the entire circumference of the filling bags, and is in contact with and biased against the inner wall of the tank body.
