Assembly process including severing part of integral collapsible pump chamber

Abstract From the Canadian patent

A collapsible pump chamber (60) is provided which includes several functional elements of a pump device (20). For example the collapsible pump chamber (60) , may be a bellows (60) which includes a functional element of an outlet valve (80), a functional element of a biasing feature and a functional element of a , spin chamber. Consequently a functional element of all of the downstream functions are incorporated into the bellows (60). This can significantly reduce costs, due to reduce tooling, and assembly for example. Since it can , be desirable to separate these functions (e.g. to achieve more consistent spray quality), a process is described for severing functions from the multiple …
