The endoscope package 125 that houses the operation section cover 126 is provided with, for example, a storage chamber 125C formed in conformity with the shape of the endoscope cover 126, and the storage chamber 125C is provided with the endoscope. The cover 126 is stored. In addition, when the lid 131 of this package, which covers the endoscope package 125, is fitted to the endoscope package 125 as shown in FIG. A transparent window 134 is formed at a position where the display member 132 of the endoscope cover 126 housed in the mirror package 125 can be visually read. The transparent window 134 is made of, for example, a transparent vinyl sheet and is airtightly attached to the package lid 131.

Therefore, when the endoscope cover 126 is packaged as shown in FIG. 8 using the endoscope package 125 and the package lid 131 having the above-described configurations, the model number of the packaged endoscope cover is The name display member 132 can be recognized at a glance. In addition, since the endoscope cover 126 is packaged and sterilized when it is packaged, the problem of contamination is expected due to the provision of the transparent window 134. Since the lid 134 is airtightly attached to the lid 131 of the package, there is no fear of contamination.

Therefore, according to the present embodiment, as shown in FIG. 10, the display member 133 of the model number and name, which is conventionally provided on the side surface side of the lid 131 of the package, is packaged without being attached. In addition to being able to recognize the contents, model number, and name of the stored items, it is possible to realize a low cost package form.

Although the transparent window 134 provided on the upper surface of the lid 131 of the package is described in the present embodiment, the present invention is not limited to this, and the transparent window 134 can be recognized, for example, from the upper side or the side. The window 134 may be extended to the side surface side of the endoscope cover 126.
