A tank and closure cap apparatus is disclosed. The tank has an upper end or top with a manhole like larger diameter opening that can be closed with a lid having a smaller diameter opening equipped with an outlet fitting. A specially configured shroud protectively covers the lid clamp and is secured with a closure cap that seals the outlet fitting.

A method for production of a tubular body applying the following steps: Pressureless application of at least one first curable plastic layer made of reactive polyurethane materials with a core via a rotational molding process, Curing the at least one plastic layer, Winding at least one reinforcement layer onto the at least one first plastic layer, Pressureless application of at least one second curable plastic layer, wherein the reinforcement layer is embedded without holes between the two plastic layers, and Removal of the core after completion of the body. Because of this, the position of the reinforcement layer 7 can be individually established and it can be ensured that the reinforcement layer will not penetrate into the first plastic layer during winding after the curing of the first plastic layer.

A tool box-used buckling apparatus includes a buckle, a sleeve, a shaft and two limiting elements. The buckle includes two substantially parallel lateral strips. The lower shaft includes a middle section inserted in the sleeve and two terminal sections inserted in the lateral strips. The limiting elements extend toward each other from the lateral strips. The limiting elements are in contact with two ends of the sleeve, thereby keeping the sleeve on the middle section of the lower shaft.

A stackable case includes a cooling and/or heating device, such as a Peltier element, so that the stackable case can be used as a cooler and/or warmer for storing beverages, food, etc. A power source device, in which a plurality of battery packs is housed, supplies power to the Peltier element and one or more fans. The power supply device has latches for detachably joining or linking it to the stackable case in a stacked manner.

A container has an opening that can be closed by a lid and latching elements for releasably locking the lid. The latching elements are arranged in a region of overlap of the container wall and the lid side wall. The latching elements are separately inserted latching elements received in latching-element receptacles, and include latching hooks. The latching hooks can be brought into engagement with inversely corresponding latching-hook receptacles when the container opening is closed by the lid.

A storage container includes a base having an interior storage volume, a lid, and a latch configured to move between an unsecured position in which the lid is movable from the closed position and a secured position in which the lid is retained in the closed position. The latch is configured to extend through an aperture defined by the lid and the base. The latch includes an extended edge to prevent the latch from passing entirely through the aperture. The latch is captured by the lid and floats within the lid portion of the aperture. The latch also includes a resilient portion configured to engage an opening in the base portion of the aperture to selectively retain the lid and the body in the closed position when the latch is in the secured position. The latch is not permanently attached to the base or to the lid.
