20.500.12556/RUL-139614 Optimizacija gibljivega spoja in vgradnja varovala pred neželenim odpiranjem na poklopni zaporki Optimization of the flexible joint and installation of a guard against accidental opening on the flip top cap Na trgu plastične embalaže se pojavljajo nove zahteve po uporabi enotnega materiala za celotno embalažo in dodanim varovalom pred neželenim odpiranjem. V magistrski nalogi smo s tem namenom prilagodili obstoječ izdelek. Oblikovali smo poklopno zaporko z različnimi oblikami gibljivega spoja, da bi našli najbolj optimalno obliko in ji dodatno vgradili varovalo. S postopkom injekcijskega brizganja smo izdelali zaporke iz polietilena, testirali trdnost in zdržljivost gibljivega spoja na upogib ter zasuk, medsebojno primerjali različne izvedbe spojev in ugotovili, da bo za povsem zanesljiv in sprejemljiv izdelek potrebna še dodatna optimizacija oblike. Ugotovili pa smo tudi, da bi se lahko s pomočjo računalniških analiz v manj iteracijah približali optimalnemu izdelku. Every day there are new requirements in the market of the plastic packaging industry. Nowadays products should be made of mono-material and should be tamper evident. In the master's thesis, we adapted an existing product. We redesigned flip top cap with installation of different living hinges to find the most optimal shape and added a tamper evident band. We have produced the caps made of polyethylene with an injection molding process, tested the strength and resistance of the living hinge to bending and rotation, and concluded that some additional optimization will be required for a completely reliable and acceptable product. We also found that with computational analysis we would probably achieve optimal product in fewer iterations. plastična embalaža poklopna zaporka gibljivi spoj bistabilna lega varovalo injekcijsko brizganje plastic packaging flip top cap living hinge bistable position tamper evident injection molding true false false [Š.
