PROBLEM TO BE SOLVED: To provide a box type case having a storage space and having a window allowing visual check of its inside, which is designed such that light that has entered through the window is sufficiently reflected to ensure visual check through the window. SOLUTION: The box type case 100 is formed in such a manner that a first half split body 10 and a second half split body 20 which are plane symmetrical, and formed almost in the shape of a box and made of a synthetic resin are integrated by vibration-welding their opening together, a liquid storage space 30 is defined in it, and a window 51 or 52 for visually checking from outside the amount of liquid stored in the storage space 30 is made in part of the first half split body 10 or the second half split body 20 such that a transparent or translucent material is fitted in the window. A light reflection part is formed on an internal part of the second half split body 20 or first half split body 10, which is located opposite the window 51 or 52. COPYRIGHT: (C)2006,JPO&NCIPI
