Whipped cream dispenser cap

Preventing deformation during the assembly process

FrieslandCampina has launched a whipped cream dispenser with a new cap. This cap consists of three plastic components that are clicked together. The nozzle and button can rotate relative to the base, thereby unlocking the packaging upon first use.

The entire assembly is clicked onto the metal canister in a single step during automation. At a late stage of the project, it was discovered that a small gap forms between the plastic parts after assembly. This is undesirable for both functional and aesthetic reasons.

As the cause and possible solution were not immediately apparent, BPO’s expertise and experience were called upon. Using FEM simulations, the capping process was analysed in detail and, within the limited design scope still available, solutions were proposed to prevent the gap from forming. With minor design adjustments, this problem was successfully resolved.

When performing FEM analyses of composite products that incorporate snap-fit connections, it is essential to properly account for freedom of movement and constraints in order to obtain realistic results. BPO has over 35 years’ experience in simulating plastic products, always adopting an approach that delivers practical, actionable results.
