A kind of urn structure,It is include an ontology,The ontology is stainless steel material,And the peripheral wall of the ontology defines to form an accommodating space,And what accommodating space top forms an opening,And the bottom system ring of the ontology sets a flange,The flange is further provided with a limited slip block,And opening system lid sets a lid,For closing the accommodating space,Thereby,Keep the urn structure difficult to slide through the limited slip block,And the anxiety of the urn structure crack-free is supplied by the stainless steel material of the ontology,To provide shockproof and anti-effect of fire,And the accommodating space is closed by the lid,Keep the urn structure completely closely sealed,And reach moisture-proof purpose.一種骨灰罐結構,其係包含有一本體,該本體為不鏽鋼材質,且該本體之周壁界定形成一容置空間,並於該容置空間上方形成一開口,而該本體之底部係環設一凸緣,該凸緣進一步設有一止滑塊,且該開口處係蓋設一蓋體,供封閉該容置空間,藉此,透過該止滑塊使該骨灰罐結構不易滑動,並藉該本體的不鏽鋼材質供該骨灰罐結構無破裂之虞,從而提供防震及防火之功效,且藉由該蓋體封閉該容置空間,使該骨灰罐結構完全密合,而達防潮之目的。
