A seat storage box having a second region adjacent to one of the second directions, and the second region opening independently of the first region.

As used herein, the outlet may constitute an opening formed in the top surface of the box body to pull the sheet out of the box body. A part of the top surface indicates a part less than half of the top surface. The outlet formed by opening a part of the top surface is formed by cleaving the perforations or the like formed on the top surface.

The first direction indicates a direction along a predetermined direction on the top surface of the box body. The second direction intersecting with the first direction indicates a direction orthogonal to a direction along a predetermined one direction on the top surface of the box or a direction along a direction intersecting the streaks. One direction of the second direction means one of the two directions of the second direction.

The first region and the second region are opened by cleaving the perforations or the like forming the outlet. The central portion of the first region includes the center (or the center of gravity) of the first region, and the length in the first direction is about one-third to one-half of the length in the first direction of the first region. Indicates the range. The fact that the second region opens independently of the first region indicates that the first region and the second region can be opened separately.

In the first aspect, a part of the top surface corresponding to the outlet is opened by a second region adjacent to the central portion of the first region and one direction of the second direction independently of the first region. , The second region can be opened before the first region is opened.

In such a configuration, the second region can be a trigger for opening an outlet on the top surface. The trigger indicates a part (or a part that triggers the opening) for starting the work of opening the outlet. Thereby, in the first aspect, it is possible to provide a seat storage box in which the outlet can be easily formed.

Hereinafter, Examples and Comparative Examples will be described.

[Example 1]
As a test body, a part 11A and 11B of the top surface 11 of the box body 10 have a length L2 extending in the first direction (X direction) and a second direction (Y direction) intersecting the first direction (X direction). The first region 30 has a first region 30 having a width W2 extending to the area 30 and a second region 40 adjacent to a central portion 35 of the first region 30 and one direction OD2 in the second direction (Y direction). When the second region 40 opens, a hanger-shaped outlet 20 (opening OP) is formed on the top surface 11, the first region 30 constitutes a cover F covering the outlet 20, and the second region 40 forms the outlet 20. The sheet storage box 100 constituting the trigger P for opening the door was evaluated for openability, generation of broken pieces, take-out property, take-out resistance value, and sheet drop. The results are shown in Table 1.

[Comparative Example 1]
An elliptical perforation is formed on the top surface of the box to form an outlet (elliptical outlet), and a resin film (window pasting film) covering the outlet is placed on the back side of the top surface. The evaluation was carried out in the same manner as in Example 1 except that the film was attached and provided with a slit extending in the longitudinal direction of the outlet (the sheet was pulled out by tearing). The results are shown in Table 1.

[Comparative Example 2]
The evaluation was carried out in the same manner as in Comparative Example 1 except that the window film was not attached. The results are shown in Table 1.

[Comparative Example 3]
The sheet storage box (S-shaped outlet) disclosed in Patent Document 2 was evaluated in the same manner as in Example 1. The results are shown in Table 1.

From Table 1, the second region 40 adjacent to the central portion 35 of the first region 30 serves as a trigger P for opening the outlet 20, and the first region 30 constitutes the cover F covering the outlet 20. The opening property, the generation of broken fragments, the take-out property, the take-out resistance value, and the sheet drop were all good (Example 1).

On the other hand, the sheet storage box provided with the oval-shaped outlet and the window-pasting film on the top surface had poor openability, generation of broken fragments, and take-out property (Comparative Example 1). Further, the sheet storage box without the window-pasting film had poor openability, generation of broken fragments, take-out property, and drop-in property (Comparative Example 2). Furthermore, although the window pasting film is not provided and the trigger is provided on a part of the top surface (the end of the outlet), the sheet storage box that does not form a cover has the generation of broken pieces, the ease of taking out, and the taking-out resistance. The value and dropability were poor (Comparative Example 3).

From these results, a first region in which a part of the top surface of the box has a given length extending in the first direction and a given width extending in the second direction intersecting the first direction, and the first A seat storage box having a central portion of the region and a second region adjacent to one of the second directions and the second region opening independently of the first region can easily form an outlet.
