Abstract: A removable covering for an object includes an adhered section that is adhered to the object (e.g., adhered to a receiving surface of the object via an adhesive layer) and a free section that is not adhered to the object. The removable covering is sufficiently flexible to allow at least partial removal of the adhered section from the object by application of a force to the removable covering. Typically, the removable covering is adhered to the object such that resistance to removal of the covering from the object varies at different zones of attachment between the removable covering and the object. The resistance variation may be achieved, for example, by employing tabs, loops, folds, varying-strength adhesive strips, textures and/or release coatings. Exemplary packaging systems (e.g., containing removable coverings and/or objects) include features such that resistance to removal of the packaging system from an object varies at different phases of removal.

Abstract: A grease and lubricating oil line coupler includes a nozzle and a receiver which can be intercoupled for grease or lubricating oil delivery. Each component has a normally closed, easily-cleanable, flush-faced mating surface, which prevents the entrance of contaminants into the free ends thereof when decoupled.

Only when the nozzle and receiver are interconnected can the valve be opened; only when the valve is closed can the nozzle be decoupled from the receiver. A high-pressure bleed-off feature returns high-pressure excess lubricant within the coupler to the lubricant storage tank when the handle of the nozzle is returned to its OFF position prior to decoupling it from the receiver.
