Problems solved by technology

Impact of the boss at the same point on the bottom of the barrel wall can cause damage to the wall or to the boss, while repeated rotation of the wheel relative to the barrel can cause the boss to wear away so it can no longer effectively perform the final alignment function

Embodiment Construction

[0013] The present invention provides a dispenser for dispensing material in the form of solid blocks or soft solids, wherein the material is propelled upwards within a barrel by a piston which is axially movable by engagement with a threaded spindle fixed to a runner wheel , the threaded spindle is fixed to a wheel mounted below the barrel; wherein, by seating a tapered boss on the bottom surface of the barrel or the top surface of the wheel to a corresponding recess on the other surface inside, aligning the bottom of the barrel with the top surface of the rotor.

[0014] Preferably, the boss is on the wheel and the dimple is on the bottom of the cartridge, at least in part because it is desirable for the cartridge to have a relatively stiff bottom. By using a hollow shaft, the rotor can be provided with a relatively flexible top surface that abuts the bottom of the cartridge. This is particularly valuable, especially when the top surface is thinned in the vicinity of the bo...

Abstract

Dispensers for a solid or soft solid mass comprise a barrel (1), a piston (12) within the barrel (1), and a mechanism for advancing the piston axially within the barrel including a rotor wheel (6). The invention provides a seating means for the rotor wheel (6) at a predetermined angular position relative to the barrel (1) comprising a boss (9a, 9b) having an inwardly tapered profile (tear drop) and a sump (3a, 3b) dimensioned to receive the boss. The boss is preferably formed on the rotor wheel (6) and the sump in the base (2) of the barrel (1). Especially desirably, the dispenser is provided with a pair of bosses and sumps, symmetrically arranged around the rotor wheel and barrel base.

Description

technical field [0001] The present invention relates to a dispenser, more particularly to a dispenser for solid blocks or soft solid substances, and in particular for dispensing cosmetic or make-up products or personal or household items. Background technique [0002] Some known containers (also known as dispensers) for solid blocks or soft solid substances, such as in particular dispensers for cosmetic or make-up products or other items for personal or household use, include: cartridges, The cartridge has an end through which the article may be dispensed, which end may be open for dispensing a solid block, or closed with a perforated cap for dispensing a soft solid substance. A runner is mounted at the opposite end of the barrel and is secured to a threaded rod extending axially within the barrel and engaging a corresponding threaded seat of the follower. A piston is positioned within the barrel. As the runner rotates, the threaded rod also rotates and engages a correspon...
