A plural preform assembly including an outer preform and an inner preform. The outer preform includes an outer preform open end, an outer preform closed end longitudinally opposed thereto, and an outer preform sidewall joining the outer preform open end and the outer preform closed end. The inner preform may be disposed in the outer preform. The inner preform includes an inner preform open end, an inner preform closed end longitudinally opposed thereto, and an inner preform sidewall joining the inner preform open end and the inner preform closed end. The inner preform has an inner preform intrinsic viscosity and the outer preform has an outer preform intrinsic viscosity. The inner preform intrinsic viscosity and the outer preform intrinsic viscosity are different. The plural preform assembly may be blow molded into an article.

An aerosol spray can has a can body, a valve assembly, a dip-tube assembly and a rigid tube. The valve assembly is mounted on the can body. The dip-tube assembly is connected to the valve assembly and has a head end channel-linked to the valve assembly. The dip-tube assembly has a flexible tube and a weight piece. The two ends of the flexible tube are connected to the valve assembly and the weight piece respectively. The rigid tube is sleeved around the flexible tube to constrain excessive bending of the flexible tube. The flexible tube protrudes from the rigid tube. The weight of the weight piece drives the tail end freely toward the ground. Therefore, the tail end stays submerged under a liquid product when less than a half of the liquid product is left inside the can body even when the can body is tilted or horizontal.

A fluid dispenser device having a reservoir; a valve; a cocking member movable between rest and primed positions and between primed and dispensing positions, the cocking member includes a set of teeth; a blocking device blocking the cocking member in the primed position; a trigger system controlled by inhaling to release the blocking device; a reservoir support element including a cam opening; and a meshing wheel having a toothed projection co-operating with the set of teeth and a cam projection co-operating with the cam opening. The toothed projection is centered relative to the wheel rotation axis, and the cam projection is offset relative to the axis. The meshing wheel completes a turn when the cocking member moves from its primed towards its dispensing position, such that the cam projection causes the reservoir support element to perform reciprocating axial movement for actuating and returning the valve into its rest position.

A beverage dispenser having replaceable dispensing components allows beverage-contacting elements to be removed and replaced. A needle or other conduit arrangement may be adapted for replacement, and the needle may be adapted to be inserted through a cork or other closure of a beverage container. A dispensing outlet may also be replaceable, allowing all beverage-contacting components to be replaced. The needle or other conduit may be engagable with a dispenser body by inserting a distal end of the needle into and through an opening in the body. A dispensing outlet may secure the needle to the body in an operation that fluidly connects the dispensing outlet to the needle.
