Ibi bikoresho mubisanzwe bikozwe muri plastiki cyangwa reberi kandi birashobora kwinjizwa mugukingura umutwe wa spray, bityo bikagabanya diameter yo gufungura kugirango bigabanye umuvuduko nubunini bwamazi asohoka. Igishushanyo gifasha kugenzura ibicuruzwa byakoreshejwe, kwirinda imyanda ikabije, kandi birashobora no gutanga ingaruka nziza kandi imwe. Abakoresha barashobora guhitamo kugabanya inkomoko ikwiranye nibyifuzo byabo kugirango bagere kubintu bifuza gutera amazi, byemeza neza kandi igihe kirekire gukoresha ibicuruzwa.
