A closure assembly for a container, the container including a raised outlet defining a dispensing opening, includes a closure body having a nestable and extendable spout formed with a generally cylindrical section, a frustoconical section, and an invertible fold between these two sections so as to enable the closure body to be either nested or extended. It is proposed to equip the semiconductor substrate located in the housing part with an identifier located directly or indirectly thereon that makes it possible to distinguish the semiconductor component from other similarly-designed semiconductor components, and which can be read out from outside the housing part using ultrasound. A latch mechanism comprises a retaining member and a lath, which engages the retaining member enabling a biasing mechanism to force the fins from a stowed position to a fully deployed position. Each toy is permanently mounted to a substrate that removably attaches to the toy station.
