Abstract: A bottle assembly has a bottle and a removable cap. The cap includes a nozzle and a vent arrangement. The vent arrangement can include a vent conduit that extends into an air cavity present at the bottom of the bottle assembly when the bottle assembly is inverted. The vent arrangement allows for pressure equalization within the bottom assembly in response to liquid being dispensed from the bottle assembly to permit high flow rates of the dispensed liquid without squeezing of the bottle.

Abstract: The present disclosure describes a shoe that may be transformed from a high heel shoe to a low heel shoe. The shoe may include three parts: a removable stelo, a removable high heel attachment, and the corresponding attachment systems integrated into the base shoe sole. The removable high heel attachment may be a standard heel of any design, width and height that has a locking system comprising a threaded post located at the heel base. When the stelo and heel attachment are attached, the shoe may be a high heel shoe. When they are removed, the shoe may be a low heel shoe, or flat shoe.
