Kule mihla, uninzi lweentengiso zemifuno zisebenzisa iibhokisi zamagwebu ukulayisha imifuno.Nangona iibhokisi zegwebu zingenamanzi kwaye zicinezela, zikhulu ngokobukhulu kwaye azinakusongwa kwaye akulula ukuzisebenzisa kwakhona.Ukongezelela, i-foam ye-styrofoam ngokwayo i-brittle kwaye kulula ukuyityumza.Yaphukile, ngoko ke ibhokisi ye-foam yibhokisi yokuguqula imifuno kuphela.

Ibhokisi yokuguqula ibhodi egotyiweyo ilungele ngakumbi ukuthuthwa kwemifuno kunye nokupakishwa, kuba ibhokisi yokuguqula ibhodi egotyiweyo yenziwe ngebhodi engenanto, engenavumba, enobuhlobo nokusingqongileyo kunye nebhodi yePP engenanto njengephepha.Ibhokisi yokuguqula ibhodi egobileyo inobunzima obulula kunye nokumelana nokwelula., Amandla aphezulu, iimpawu zokufuma kunye neempawu zokungena kwamanzi, kunye nobunzima obukhulu, akulula ukutyunyuzwa, nokuba ucinezelwe ngumxhuzulane, ukhubazeke kancinane kuphela.Emva kokuba amandla okucudisa esusiwe, asenokubuyiselwa kwimeko yawo yangaphambili.Qhubeka usebenzise.

Olona phawu lukhulu lwebhokisi yokujika yebhodi egotyiweyo kukuba inokusongwa kwaye igcinwe emva kokuba imveliso yothutho lwemifuno igqityiwe.Xa kuthelekiswa nebhokisi yokuguqulwa kwe-foam yendabuko, indawo yokugcina ibhokisi yokuguqula iyancipha kakhulu, kwaye ingaphinda isetyenziswe kwaye isetyenziswe kwakhona.Ngokwemfuno, ibhokisi yokuthengisa imifuno enemibala eyahlukeneyo ingaphuhliswa, kwaye umphezulu unokuprintwa okanye ufakwe kwi-peritoneum, engabonisa ulwazi lweemveliso zemifuno ngokucacileyo ngakumbi.

Kwindawo yokuhlala yangoku ekhuthaza ukukhuselwa kwendalo, ibhokisi yokuguqula ibhodi egobileyo ihambelana nokusingqongileyo kunebhokisi yefoam ye-styrofoam.Inkqubo yenguqu yothutho lwemifuno yexesha elizayo iya kuba nemfuno eyonyukayo yebhokisi yenguqu yebhodi esongwayo.
