A pair of inner side walls 12 and 12 stand upright from positions slightly shifted inward from the pair of long side surfaces of the bottom plate 11, respectively. The inner side walls 12, 12 and the bottom plate 11 constitute a base portion 13 according to the present invention. The height from the lower surface of the bottom plate 11 to the upper end of the inner side wall 12 is slightly lower than the height from the bottom surface 51 of the container 50 to the upper surface of the side wall 52 (see FIG. 6).

  In addition, the bottom plate 11 and the inner side wall 12 are made of resin cardboard generally called “plastic cardboard” or “plastic cardboard”. The inner side wall 12 is fixed (for example, bonded or welded) to the bottom plate 11.

  As shown in FIG. 2, one end of the cover sheet 20 is fixed to the upper edge of each inner side wall 12. The cover sheet 20 has a rectangular shape slightly larger in the vertical direction than a rectangular shape in which two inner side walls 12 are arranged in the vertical direction, and is folded in half along the vertical direction. Then, the bent portion 21 of the cover sheet 20 is located at the lower end, and one upper edge of the cover sheet 20 is fixed on the upper edge of the outer surface of the inner side wall 12 (for example, bonded or welded). Have been. The cover sheet 20 is made of, for example, a transparent or translucent resin.

  The free end of the cover sheet 20 is reinforced by a sheet reinforcing member 22. The sheet reinforcing member 22 is a strip-shaped resin plate extending in the width direction of the cover sheet, and is fixed in a state where the free end of the cover sheet 20 is superimposed on a surface facing the side opposite to the inner side wall 12 ( (For example, adhesion or welding).

  At the center of the free end of each cover sheet 20 in the lateral direction, both end portions of a resin-made belt member 24 folded in half are fixed on the front and back of the cover sheet 20 (for example, adhered or welded). . A portion of the belt member 24 that protrudes from the cover sheet 20 and forms an annular shape is the handle portion 23. Also, the first and second hook-and-loop fasteners 25 and 26 (corresponding to the “closer holding means” of the present invention) are attached to portions of the belt member 24 fixed to the cover sheet 20 in a state where they are overlapped. Have been. More specifically, the first surface fastener 25 of the cover sheet 20 facing the inner side wall 12 has, for example, a first structure having a plurality of hook-shaped protrusions (not shown), and a first surface fastener 25 on the opposite side. The second hook-and-loop fastener 26 has a second structure having a plurality of ring portions (not shown).

  Then, as shown in FIG. 5, both the cover sheets 20, 20 are pulled out from the upper end portions of the inner side walls 12, 12, and the free end of any one of the cover sheets 20 and the free end of the other cover sheet 20 are removed. , The first hook-and-loop fastener 25 of one cover sheet 20 is engaged with the second hook-and-loop fastener 26 of the other cover sheet 20, and the inner cover 10 is closed.

  A weight member 27 (corresponding to “biasing means” of the present invention) is placed inside the bent portion 21 of the cover sheet 20. As shown in FIG. 2, the weight member 27 is formed of a metal pipe having a circular section and substantially the same length as the width direction of the cover sheet 20.

  A string member 28 as a “separation restricting means” according to the present invention is inserted into the weight member 27, and both ends thereof are connected to four corners of the bottom plate 11. More specifically, the string member 28 is a resin molded product and has ring portions 28A shown at both ends in FIG. On the other hand, at four corners of the bottom plate 11, a through hole 11A penetrating vertically through the side surface of the bottom plate 11, and a cut portion 11B communicating between the through hole 11A and the side surface of the bottom plate 11 are formed. Then, the ring portion 28A of the string member 28 is connected to the through-hole 11A so as to extend between the cut portions 11B. In addition, the string member 28 may be configured to be simply connected through the through hole 11A of the bottom plate 11.

  As shown in FIG. 2, when the weight member 27 moves to a substantially central position in the vertical direction on the inner side wall 12, the string member 28 is in a stretched state, and further restricts the weight member 27 from moving upward. . Thus, the movable range of the weight member 27 is restricted between the substantially middle position and the lower end position of the inner side wall 12 in the vertical direction. When the inner cover 10 is in the closed state shown in FIG. 3, the weight members 27, 27 of the two cover sheets 20, 20 are located slightly below the upper end of the movable range.

  The description of the configuration of the inner cover 10 of the present embodiment is as described above. The inner cover 10 is closed and assembled in the container 50, for example, as shown in FIG. Then, as shown in FIG. 5, the pair of inner side walls 12, 12 of the base portion 13 are separated from the pair of side walls 52, 52 on the pair of long sides of the container 50 by gaps 49, 49 from inside. The upper ends of the inner side walls 12 and 12 face each other and are located slightly below the upper ends of the side walls 52 and 52.

  In this state, for example, the handle portion 23 of one cover sheet 20 located on the upper side is pinched and the free end of the cover sheet 20 is bent. Then, the first and second hook-and-loop fasteners 25 and 26 of both cover sheets 20 and 20 are disengaged, and the other cover sheet 20 is automatically drawn into the gap 49 by the load of the string member 28 and accommodated therein.

To cover the baggage L with the inner cover 10, the handle portions 23, 23 of both cover sheets 20, 20 are pinched and pulled out from the gaps 49, 49, and any one of their free ends is overlaid on the other. I just need. Then, as shown in FIG. 5, the first hook-and-loop fastener 25 of one cover sheet 20 and the second hook-and-loop fastener 26 of the other cover sheet 20 are engaged, and the inner cover 10 is held in a closed state. The luggage L is covered by the cover sheets 20, 20 from above. Further, when taking out the baggage L, as described above, the inner cover 10 can be easily opened by gripping the handle 23 of one cover sheet 20 and bending the free end of the cover sheet 20. it can.

  As described above, the inner cover 10 of the present embodiment can be easily opened without removing the inner cover 10 from the container 50. This prevents the inner cover 10 from being lost and facilitates the opening operation of the inner cover 10 in a limited space. Further, when the inner cover 10 is opened, the cover sheets 20, 20 are accommodated in the gap 49 in the container 50, so that adhesion of dirt to the cover sheets 20, 20 is prevented.

  In order to draw the cover sheet 20 into the gap 49, a weight member 27 extending in the width direction of the cover sheet 20 is placed inside the bent portion 21 of the cover sheet 20, and furthermore, in the width direction of the cover sheet 20. Since the extending sheet reinforcing member 22 is fixed to the free end of the cover sheet 20, tension can be easily applied to the entire cover sheet 20, so that the cover sheet 20 can be easily opened and closed. Further, since the movement range of the weight member 27 is regulated by the string member 28, the weight member 27 does not fall out of the gap 49 even when the container 50 is tilted, so that the container 50 having the inner cover 10 can be easily handled. Become.
