By the way, the endoscope cover 2A for covering the cover endoscope 2B is generally housed in a cover package, sterilized, and packaged. In other words, it keeps the sterilized state by packaging. FIG. 5 shows an example in which such a sterilized state can be discriminated at a glance.

In FIG. 5, the cover package 150 is composed of a lid portion and an accommodating portion fitted to the lid portion, which is not shown, and the endoscope cover is accommodated in the accommodating portion and sterilized. It is packaged. In view of this, the present embodiment is characterized in that the display unit 151 indicating that the product has been sterilized is provided on the exterior portion of the cover package, for example, in front of the lid of the cover package 150. The display unit 151 is displayed by means such as printing, printing or sticker.

According to the cover package 150 having such a configuration, when the cover package 150 is delivered to the user, for example, it can be recognized at a glance that the product is a sterilized product. Further, by clearly informing the user (operator) that the product is a sterilized product, it is of course possible to immediately use it for inspection without performing a work of confirming whether or not it is sterilized.

In this example, the display unit 151 shows a sterilized state, but it may be displayed as a non-sterilized state that has not been sterilized.

If the sterilization method of the cover package 150 is ethylene oxide or sterilization, for example, a commercially available seal-like (E, O, gas sterilized confirmation indicator) is used as the display unit 151. You may use it.

FIG. 6 is a perspective view of the cover package 150 showing an example of reducing the storage space of the cover package 150 of FIG. 5, and FIG. 7 is a cross-sectional view showing a state in which the cover packages 150 of FIG. 6 are stacked. Is.

As shown in FIG. 6, the cover package 150 has a convex portion 152 on the upper surface and a concave portion 153 on the lower surface. Further, for example, when a plurality of cover packages 150 are vertically stacked as shown in FIG. 7, the convex portion 152 and the concave portion 153 can be fitted to each other.

According to such a configuration, even when stacked vertically, as shown in FIG. 7, the convex portion 152 and the concave portion 153 stacked on the cover package 150 are fitted to each other. Since it is fixed, the load will not collapse.

Therefore, generally, a large amount of disposable products such as an endoscope cover is a disposable product, and thus it is necessary to prepare a large amount of the disposable products. Therefore, according to this example, a large amount of the cover package 150 must be stored. Even when piled up high, it is possible to prevent collapse of loads, etc. Moreover, it is possible to effectively use a storage space in a small space. That is, it is possible to reduce the storage space.

FIG. 8 shows another example of the cover package 150 of FIG. 6, and is a perspective view of the cover package 150 in which the convex portion 152 and the concave portion 153 are provided on part of the upper surface and the lower surface, respectively.

As shown in FIG. 8, the cover package 150 has a convex portion 152 provided on a part of the upper surface, for example, near the center, and a concave portion 153 provided on the lower surface at a position where the convex portion 152 can be fitted. There is.

With such a configuration, even when a plurality of cover packages 150 are vertically stacked, the convex portion 152 can be fitted and fixed in the concave portion 153 of the cover package 150 stacked thereon. . As a result, the cover packages 150 can be stacked high even in a storage space of a small space.

Therefore, also in this embodiment, the effect of reducing the storage space can be obtained as in the case of the above embodiment.

In this example, the sizes of the convex portion 152 and the concave portion 153 are such that the endoscope cover can be securely housed, and the sterilized state can be sealed and fitted and fixed even when stacked. If so, a size other than this example may be used.

FIG. 9 shows an example in which the storage space of the cover package 150 of FIG. 5 is made small, and is a perspective view of the hanging type cover package 150, for example.

As shown in FIG. 9, the cover package 150 has a suspending member 150 A extending from the upper portion of the cover package 150. Further, a suspending hole 155 is provided near the center of the suspending member 150A so as to penetrate a storage hook member 154 that is provided so as to project horizontally from a wall, for example.

With such a configuration, the cover package 150 can be stored in a state in which the suspension hole 155 provided in the cover package 150 is hooked by the storage hook member 154, that is, in a suspended state.

Therefore, according to this example, when the cover packages 150 as shown in FIG. 6 or other packages are piled up, it is difficult to take out the piled up packages. As shown in FIG. 9, by adopting the hanging type, it is possible to easily take out and reduce the storage space. FIG. 10 is a further improvement of the hanging type cover package 150 of FIG. 9, and is characterized in that a hanging member 150B is also provided at the lower portion of the cover package 150, for example.

As shown in FIG. 10, a suspending member 150B of the same size as the suspending member 150A, for example, is provided below the suspending cover package 150 of FIG. Further, a hanging hole 155 is also provided in the hanging member 150B. A suspending tool 156 is locked in the suspending hole 150B, and another cover package 150 is suspended from the suspending tool 156.

According to such a configuration, as shown in FIG. 9, for example, since the number of cover packages 150 suspended from one storage hook member 154 is limited, many storage hook members 154 are provided. Although necessary, it is possible to suspend the cover package 150 up and down by providing suspending members 159A and 150B and suspending tools 156 for locking them on the upper and lower sides of the cover package 150, respectively. That is, a single storage hook member can store more cover packages 150. Therefore, the length of the storage hook member 154 can be shortened and the storage space can be reduced.

FIG. 11 is a partially broken perspective view of the cover package 150, which is characterized in that a hook-shaped suspending portion 157 is provided in place of the suspending member 150B provided at the lower portion of the cover package 150 in FIG. It is a figure.

As shown in FIG. 11, a hook-shaped suspending portion 157 is provided in place of the suspending member 150B provided at the bottom of the cover package 150 in FIG. The other constitutional requirements, actions and effects are the same as those in FIG. In the illustrated example shown in FIGS. 9 and 10, for example, when using the one stored in the back, one of the hanging holes 155 of the hanging member 150A provided on the upper portion of the cover package 150 is used. A cut may be made in the portion so that the storage hook member 154 can be taken out with a pulling force such that the storage hook member 154 is not bent.
