| 摘要 |
The present invention provides a product case capable of checking whether the case is opened or closed, which may be partially damaged if the case is firstly opened or a pressure is applied. The present invention comprises a lower case (100) formed by a bottom surface (110) having a set shape, one or mode side walls (120) extended upward from a side of the bottom surface, and one or more coupling parts (140) constructed on the bottom surface (110) of the lower case (100) and/or an arbitrary side wall (120) connected to the bottom surface (110) and formed in one body to be coupled to an insertion body inserted from above for forming a set accommodation space for storing a set material or product; and an upper case (200) having one or more coupling bars (220) extended downward to be correspondingly assembled with an upper end of the lower case (100). The coupling bars (220) coupled to the coupling parts (140) are partially or entirely damaged if a regular pressure is applied to the lower case (100) and/or the upper case, (200) or the lower case (100) or the upper case (200) is forcibly separated. |
