Isigaba sobude/usayizi

Amakesi okuvikela ukuphepha abonakala ngokuqina okuqinile kanye nokuvikela okunokwethenjelwa kwemvelo. Ngokuvamile akhiwe ngezinto ezifana ne-ABS, i-polypropylene, anikeza ukumelana okuphezulu komthelela. Izici ezibalulekile zifaka phakathi izivalo ezingangeni manzi nezingenathuli, ama-valve okulinganisa ingcindezi, kanye nokufakwa kwe-foam okwenziwe ngokwezifiso ukuze kuvikelwe ngokuphephile. Ama-latches aqinile, amakhona aqinisiwe, namasondo angakhethwa athuthukisa ukuphathwa kanye nokuthuthwa. Lawa makesi ahlinzeka ngokuvikelwa okubalulekile kwemishini ebucayi ekushaqekeni, umswakama, kanye nezimo ezimbi kakhulu ngesikhathi sokuthutha noma sokugcina, okwenza kube yinto ebalulekile emkhakheni wezempi, wezimboni, wezokwelapha, kanye nowe-elekthronikhi.
