A hand-held dispenser including a container having a dispensing neck portion provided with an exterior, annular locking-type retention bead and a nozzled dispenser cap adapted to be forcibly applied to the neck portion and to be permanently retained thereon. The container neck portion has a circumferentially facing abutment shoulder disposed above its bead, and the cap has an internal locking-type retention bead cooperable with the bead on the neck portion. The cap also has a locater lug which can engage the abutment shoulder of the neck portion during initial relative turning application of the cap, thereby to halt the latter in a predetermined rotative position. A recess on the neck portion receives the locater lug as the cap, subsequent to its halting, is axially applied. The arrangement is such that the cap will always be positioned on the neck portion at a fixed, rotative position. This construction is of value with dispensers intended to discharge liquid in the form of a lateral stream, as well as with dispensers of the type which are non-cylindrical or otherwise assymetric about a central axial line. |
