Umufuka w'amazi wo hasi ufite ishusho yihariye, ukozwe mu ruganda, ufite ishusho yihariye y'umufuka wo hasi, ufite umufuka wo hejuru w'ibiryo by'abana.

Isakoshi y'umufuka wo guhagarara ni uburyo bushya bwo gupakira, kandi inyungu yayo ikomeye kuruta uburyo busanzwe bwo gupakira ni uburyo bwo gutwara; isakoshi y'umupfundikizo yigenga ishobora gushyirwa mu gikapu cyangwa mu mufuka, kandi ishobora kugabanuka uko ibikubiye mu gikapu bigabanuka, byoroshye kuyitwara. Ifite inyungu mu kunoza ireme ry'ibicuruzwa, ikongera ubushobozi bwo kureba mu gikapu, koroshya gutwara, koroshya kuyikoresha, kuyibika no kuyifunga. Isakoshi y'umupfundikizo yigenga irambitse hakoreshejwe imiterere ya PET/foil/PET/PE, kandi ishobora kandi kugira imiterere ibiri, imiterere itatu n'ibindi bikoresho bifite ibindi bisobanuro. Biterwa n'ibicuruzwa bitandukanye bigomba gupakirwa. Isakoshi yo kurinda umwuka ishobora kongerwaho uko bikenewe kugira ngo igabanye ubushobozi bwo kwinjira mu kirere, bityo yongere igihe cyo gukoresha.

Gupfunyika ibinyobwa bidasembuye ku isoko ahanini biri mu macupa ya PET, amasashe y'impapuro za aluminiyumu, n'amacupa. Muri iki gihe, hamwe n'irushanwa rigaragara cyane ryo guhuza ibintu, kunoza uburyo bwo gupfunyika nta gushidikanya ko ari bumwe mu buryo bukomeye bwo gupiganwa butandukanye. Isashe yishingikiriza ihuza gupfunyika kenshi kw'amacupa ya PET n'imideli y'amasashe y'impapuro za aluminiyumu. Muri icyo gihe, ifite kandi ibyiza bitagereranywa byo gupfunyika ibinyobwa gakondo mu mikorere yo gucapa. Bitewe n'imiterere y'ibanze y'isashe yishingikiriza, agace k'isashe y'umunwa kanini cyane kuruta icupa rya PET, kandi ni keza kuruta ipaki nk'isashe idashobora kwihanganira. Birumvikana ko kubera ko isashe y'umunwa iri mu cyiciro cy'udupfunyika tworoshye, ntabwo ikwiriye gupfunyika ibinyobwa birimo karubone, ariko ifite ibyiza byihariye mu mitobe y'imbuto, ibikomoka ku mata, ibinyobwa by'ubuzima, ibiryo bya jelly, nibindi.

Ipaki y'umufuka wo guhagarara ikoreshwa cyane cyane mu binyobwa by'umutobe w'imbuto, ibinyobwa bya siporo, amazi yo kunywa ari mu macupa, jeli ibasha kunyurwamo, ibirungo n'ibindi bicuruzwa. Igenda yiyongera buhoro buhoro.

Agafuka gafata umunwa gafasha umuntu kwisukira cyangwa kunyunyuza ibirimo, kandi gashobora kongera gufungwa no gufungurwa icyarimwe, ibyo bikaba bishobora gufatwa nk'uruvange rw'agafuka gafasha umuntu kwisukira n'umunwa usanzwe w'icupa. Ubu bwoko bw'agafuka gafasha umuntu kwisukira muri rusange gakoreshwa mu gupfunyika ibintu by'ingenzi bya buri munsi, kandi gakoreshwa mu gushyiramo ibintu by'amazi, ibinyobwa bya colloidal n'ibikomeye nk'ibinyobwa, gel zo kwiyuhagira, shampoo, ketchup, amavuta yo kurya, na jeli.

Imiterere yihariye y'isakoshi y'umunwa, irashishikaje amaso, yoroshye gukurura ibitekerezo by'abakiriya, abakiriya benshi b'ibiryo by'abana bakunda ubwoko bw'ibipfunyika. Umunwa wo hejuru urashobora kongera gukoreshwa, ni ingirakamaro kandi biroroshye, ishusho y'izipu yo hasi ni nshya, ishobora gukoreshwa mu kuzuza amazi no gukora ahantu ho kugurisha, byose bishyigikira uburyo bwihariye bwo guhindura, kugira ngo habeho imiterere yihariye kandi idasobanutse y'ikirango.
