[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box sheet for wrapping and protecting wrapping bags such as fertilizer bags stacked on a pallet in a stacked state.

[0002]

2. Description of the Related Art Conventionally, a large number of wrappers such as fertilizer bags are transferred,
In the case of storage, the wrappers are stacked on the pallet via a slip sheet so as to have a predetermined three-dimensional shape (or the wrappers may be stacked directly on the pallet). They are transported and stored. Some fertilizer and other contents of the wrapper do not require much indoor storage management in a warehouse or the like. In that case, these zippers are stacked in a pile,
A sheet is placed on the stacked wrapping bags to prevent dirt due to dust and the like, and to prevent wetting by rain, snow and the like.

[0003] To explain this, as shown in Figs. 4 and 5, a slip sheet b having excellent lubricity is laid on a lowermost pallet a, and a wrapper c is placed on the slip sheet b to have a substantially rectangular planar shape. It is stacked in such a three-dimensional shape, and is further covered with a box sheet d which is a bag body with an open bottom surface so as to cover this and the slip sheet b. The box sheet d has a pair of side faces e opposed to each other, and a stretchable rubber band f is squeezed and narrowed down, and a through hole h opened at the center of the lower edge of the other set of side faces g.
Then, a rubber band f passing under the slip sheet is hooked (only one side is shown in FIG. 4).

[0004]

However, in the above-described method of fixing the box sheet, the lower edge portion may be turned up and dust or water may enter into the inside from the lower edge portion. When using the slip sheet, there is a problem that the box sheet hanging on the slip sheet swells and water easily accumulates here. There is also a problem that the work of fastening the box sheet becomes complicated.

[0005] Therefore, in the present invention, it is an object of the present invention to ensure that the box sheet covers the stacked wrapping bags, and to easily perform the fastening work of the box sheet. The purpose is to protect.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems, and has a top surface and four side surfaces corresponding to the stacked shape of a plurality of wrappers stacked in a predetermined three-dimensional shape on a pallet. A waterproof bag having an open lower surface, and a lower-slip rope guide is provided on each lower edge of the four side surfaces along a lower edge skirt portion excluding a lower edge edge of the side surface. A rope having high lubricity passing through the rope guide with ring portions at both ends is provided so as to make a round around the bag body over the four side surfaces, so that the bag body can be narrowed down. A box sheet characterized in that the ring portion is inserted and folded back, and the one ring portion is provided so as to be able to be fixed to the bag body in a tensioned state via an extensible tension member, This is to solve the above-mentioned problem.

[0007]

In the present invention, by tightening the rope, each of the rope guide portions through which the rope passes can be narrowed, and the corner portion where the side surfaces are connected does not have the rope guide, so this corner portion is also easy. Will be narrowed down to. Further, since the rope guide portion above the lower edge skirt portion is narrowed down, when the box sheet covers the wrapping bags stacked on the pallet, the lower edge skirt portion comes to hang on the pallet, It increases airtightness.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on one embodiment shown in FIGS. In the figure, reference numeral 1 denotes a box sheet. The box sheet 1 has a top surface 2 and four side surfaces corresponding to the stacked shape of a plurality of wrappers c stacked in a predetermined three-dimensional shape on a pallet a via a slip sheet b. 3
And is formed as a waterproof flexible bag having an open lower surface.

[0009] The box sheet 1 has the structure shown in FIG.
As shown in FIG. 2 (which shows a four-sided deployed state), on each of the side surfaces 3, a flexible and highly slippery rope guide 5 is provided above and along the lower edge skirt portion 4. Is provided except for the lower edge corner 6 side, that is, provided except for the corner portion. Also, 7
Is a highly slippery rope, which passes around the lower edge through each of the rope guides 5 as shown in FIG. Both ends of the rope 7 have ring portions 8, and the rope 7 is folded back so that the other ring portion 8 passes through the ring portion 8 located at the corner portion, and provided at the other corner portion. The ring portion 8 at the tip of the rope is fixed to the through hole 10 of the tongue piece 9 via an extendable tension member 11.

At the time of use, as shown in FIG. 3, the box sheets 1 are put on the lowermost pallet a from the stacked packets c, and the rope 7 passed through one ring 8 is drawn and drawn. Then, the portion of the rope guide 5 of the box sheet 1 is narrowed down so as to wrap the wrapper c and the slip sheet b. At this time, the corners between the rope guides 5 can be easily narrowed down because there is no rope guide. Further, the lower edge skirt portion 4 hangs on the peripheral edge of the pallet a, so that the airtightness is improved. For example, as shown in FIG.
And a pair of hooks 13, which are hung over the ring portion 8 of the rope 7 and the through hole 10 of the tongue piece 9 to keep the rope 7 in a tensioned state.

In the above embodiment, an example is shown in which a pallet is covered with a wrapping bag stacked via a slip sheet, but, of course, the box sheet of the present invention is wrapped without using a slip sheet. It can also be used to cover bags.

[0012]

[Effects of the Invention] As described above, according to the present invention,
The box sheet is a waterproof bag body having a top surface and four side surfaces corresponding to the stacked shape of a plurality of wrapping bags stacked in a predetermined three-dimensional shape on a pallet, and a lower surface being opened, At each lower edge of the side surface, a highly slippery rope guide is provided along the lower edge skirt portion except for the lower edge of the side edge, and a high slippery rope having an annular portion at both ends and passing through the rope guide is provided in all directions. The bag is provided so as to be able to be squeezed by making a round around the bag over the side surface, and the rope is folded so that one ring is inserted through the other ring, and the one ring is stretchable by pulling. It is characterized in that it is provided so that it can be fastened to the bag body in a tensioned state via a member. Thus, if the rope is drawn down over the wrapper, the rope guide is narrowed down, and the corners are narrowed down without being bulky due to the absence of the rope guide. Then, since the drawn rope is stopped via the pulling member, the fastening portion is one place, so that the mounting operation of the box sheet and the removing operation thereof are extremely simple. And, when the rope is narrowed, the lower edge skirt portion of the box sheet is hung on the pallet, so that the airtightness inside the box sheet is increased, and a better state is obtained, and an effect excellent in practicality is obtained. To play.
