The present invention relates to a structure of a box body, the box body comprising a cover body member and a box body member, the cover body member having a main top surface portion, a bottom surface portion, two side surfaces and an end surface portion, and further the cover member Forming an accommodating area, the box component has an accommodating space, and a flange is provided on a top periphery of the accommodating space of the box component, and the length of the bottom surface and the side surfaces of the cover component are smaller than the main a top surface portion, a notch portion is formed at one end of the cover member, and the inner surface of the cover member and the inner surface of the end surface portion are provided with a rail groove, and the box member is combined with the notch portion at one end of the cover member into the accommodating region thereof, The casing element flange is combined into the rail groove of the cover body member to close the accommodating space of the casing member, and a hollow portion is formed on the end surface portion of the cover member, so that when the casing is to be opened, the hand can be opened. Grasping the two sides of the cover member, and then pushing out the box member by the hollow portion of the end portion, the box member can be easily pushed out and separated from the cover member, and a card is provided on the bottom surface of the main top surface of the cover member. Protrusion After the lid member and the cartridge member binding, will enable the clamping portions projecting in the cassette clamping element corresponding to the inner side edges, the elements of the cartridge positioning purposes.本創作係有關一種盒體之結構，該盒體包括一蓋體元件及一盒體元件，該蓋體元件具有一主頂面部、一底面部、兩側面部及一端面部，進而於蓋體元件上形成一容置區，該盒體元件係具有一容置空間，於盒體元件容置空間之頂部周緣設有凸緣，前述構成蓋體元件之底面部與兩側面部之長度係小於主頂面部，使蓋體元件一端形成一缺口部，於蓋體元件該兩側面及端面部內面，設有軌槽，將盒體元件由蓋體元件一端缺口部結合進入其容置區內，將使盒體元件凸緣組合進入蓋體元件之軌槽內，進而將盒體元件之容置空間予以封閉，於蓋體元件之端面部形成有一鏤空部，以於欲開啟盒體時，可手握蓋體元件兩側面部，再由端面部之鏤空部將盒體元件推出，即可輕易將盒體元件推出與蓋體
