Umlando wezinkomishi zephepha uhamba ngezigaba ezine: izinkomishi zephepha ezi-conic/ezinamaphiko izinkomishi zephepha zokuqala zaziyi-conic, zenziwe ngesandla, zihlanganiswe ndawonye, kulula ukuzihlukanisa, futhi kwakudingeka zisetshenziswe ngokushesha ngangokunokwenzeka.Kamuva, izinkomishi ezigoqayo zengezwa ezindongeni eziseceleni ukuze kwandiswe amandla ezindonga ezisemaceleni kanye nokuqina kwendebe, kodwa kunzima ukuphrinta amaphethini kulezi zindawo ezigoqayo, futhi umphumela awumuhle kakhulu.I-Waxed Paper Cup ngo-1932, inkomishi yokuqala yephepha ene-wax yokuqala yaphuma, indawo yayo ebushelelezi ingaphrintwa kumaphethini ahlukahlukene amahle, ithuthukise umphumela wokuphromotha.Ngakolunye uhlangothi, ukugcoba kwe-wax enkomishini yephepha kungagwema ukuthintana okuqondile phakathi kwesiphuzo kanye nezinto zephepha, futhi kungavikela ukunamathela futhi kuthuthukise ukuqina kwendebe yephepha;ngakolunye uhlangothi, iphinde ikhulise ukushuba kodonga oluseceleni, ukuze amandla enkomishi yephepha athuthukiswe kakhulu, ngakho-ke, ukusetshenziswa kwephepha okudingekayo ekukhiqizeni izinkomishi zephepha eziqinile kuyancipha, futhi izindleko zokukhiqiza ziyancipha.Njengoba izinkomishi zephepha elinengcina ziba iziqukathi zeziphuzo ezibandayo, abantu banethemba lokuthi bazosebenzisa isitsha esikahle sokuphuza iziphuzo ezishisayo.Kodwa-ke, iziphuzo ezishisayo zizoncibilikisa i-wax ngaphakathi kwendebe, umlomo wokunamathisela uzohlukaniswa, ngakho-ke inkomishi yephepha evamile ehlanganiswe nge-wax ayifanele ukubamba iziphuzo ezishisayo.
I-Straight-wall double-layer Cup, ukuze kwandiswe ububanzi bokusebenza, ngo-1940, i-straight-wall double-layer Cup yethulwa emakethe.Inkomishi yephepha ayilungele ukuthwala kuphela, kodwa futhi ingasetshenziswa ukubamba iziphuzo ezishisayo.Kamuva, abakhiqizi kulezi zinkomishi ezimbozwe nge-latex ukuze bamboze izinto zephepha "ngephunga lekhadibhodi" futhi baqinise ukuvuza kwenkomishi yephepha.Izinkomishi ze-wax zongqimba olulodwa ezinamekwe nge-latex zisetshenziswa kakhulu emishinini yokuthengisa ukuze kubanjwe ikhofi elishisayo.Coated paper izinkomishi, ezinye izinkampani ukudla zaqala polyethylene camera ekhadini ukwandisa umgoqo kanye uphawu of emaphaketheni iphepha.Ngenxa yokuthi indawo yokuncibilika ye-polyethylene iphakeme kakhulu kune-wax, inkomishi yephepha yesiphuzo yohlobo olusha embozwe nge-polyethylene ingasetshenziselwa ukubamba iziphuzo ezishisayo.Ngesikhathi esifanayo, polyethylene enamathela ukwedlula wax original enamathela bushelelezi, ngcono ukubukeka iphepha izinkomishi.Ngaphezu kwalokho, ubuchwepheshe bayo bokucubungula kunokusebenzisa indlela yokugqoka i-latex ishibhile futhi ngokushesha.
