Abstract

A dispensing container including a receptacle portion for holding liquids and an upper opening having a closure device. The closure device is embodied in threaded cap which closes a relatively large opening in the top of the receptacle portion for filling purposes. The closure device includes a spout connected to the threaded cap for sliding movement between open and closed positions. The spout includes a plug member having a resilient static sealing element. A tubular closure element is secured to the threaded cap and includes a plug bore which receives the plug member and further defines a fluid flow path. A resilient dynamic sealing element is disposed on an outer surface of the tubular closure element and the dynamic sealing element is in continuous contact with an inner surface of the spout during sliding movement thereof. The tubular closure element further includes an upper sealing surface adapted to engage the static sealing element and apply axial compression thereto when the spout is in a closed position. A flip-top protective cover is connected to the threaded cap and, in a closed position, the protective cover maintains the static sealing element in axial compression against the sealing surface.
