BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet roll storage case for storing a sheet roll formed by winding a packaging sheet such as a plastic film wrap, an aluminum wheel, and paper into a roll shape.

[0002]

2. Description of the Related Art As a conventional sheet roll storage case of this type, there is a lap roll storage case as shown in FIGS. 5 to 8, for example. A box base plate Y is obtained by cutting a piece of thick paper into a predetermined shape and fold processing (dashed line L part)
Is formed, and the box original plate Y is assembled and formed in an elongated box shape as shown in FIG.

In this conventional lap roll storage case,
It has a case body 101 for accommodating the lap roll 108 and a cover plate 103. The lid plate 103 is the case body 101.
Of the opening 102 on the long side (the edge of the first plate portion 111) is integrally continuous with the opening covering plate portion 131 that covers the opening 102 and the plate portion that faces the opening 102 ( The second plate portion) 112 is a superposed plate portion 132 that is superposed on the outer surface.
have. A tear perforation 134 is formed in the overlapping plate portion 132 at an intermediate position in the projecting width direction.
Further, the front side plate portion 135 of the overlapped plate portion 132, which is on the front side of the perforations 134, stores the lap roll 108 in the case body 101, and then uses the adhesive S to form the case body 1
No. 01 is temporarily adhered to the outer surface of the second plate portion 112.

When this conventional wrap roll storage case is used, the front side plate portion 135 is peeled off from the temporary adhesive portion (symbol S portion) as shown by a chain line 135 'in FIG. To remove. still,
The cut front side plate portion 135 is discarded as it is. Then, in order to take out the wrap from the wrap roll 108 in the case body 101, the unwinding end 181 of the wrap is passed through the opening 102 of the case body 101 from the second plate portion 112 and the remaining plate portion (base plate) of the overlapping plate portion 132. After pulling out a predetermined length through the (portion) 136, the pulled wrap may be applied to the knife 104 provided in the case body 101 to cut. When the wrap is cut, the base plate portion 136 of the overlapping plate portion 132 is pressed with a thumb to hold the wrap.
And the second plate portion 112 is sandwiched between the two.

[0005]

However, in the conventional lap roll storage case shown in FIGS. 5 to 8, the lap take-out side plate portion (the second plate portion) 112 of the case main body 101 is made of only one thick paper sheet. Because it is configured
Even a small pressing force (for example, the pressing force generated when pressing the base plate part when cutting the lap) easily deforms,
There was a problem that the lap roll storage case had to be handled carefully (the wrap roll storage case would be damaged if handled roughly). Further, if the wrap take-out side plate portion (second plate portion) 112 is deformed, wrinkles are likely to occur in the wrap when the wrap is pulled out, and it is difficult to pull out the wrap cleanly.

It should be noted that it is conceivable to reinforce the lap take-out side plate portion 112 of the case main body 101 by some method (for example, to attach a reinforcing member), but in that case, a work for reinforcement and a reinforcing member by a separate process. Is required, resulting in an increase in cost.

In view of the problems of the conventional lap roll storage case described above, the present invention utilizes the front side plate part of the superposed plate part which has been conventionally discarded without any special reinforcement work. The purpose is to enable the storage case to be reinforced.

DISCLOSURE OF THE INVENTION The present invention provides a case body having an elongated box shape having a U-shaped cross section in which a first plate portion and a second plate portion facing each other are connected by a third plate portion. First of the case body
An opening covering plate part extending from the edge of the plate part and covering the opening of the case body, and an overlapping plate part continuous with the opening covering plate part and covering substantially the entire outer surface of the second plate part. In a sheet roll storage case made of a paper box with a lid plate,
A slit having a length equal to or larger than the sheet width of the sheet roll accommodated in the case body is formed at an intermediate position in the short width direction of the second plate portion of the case body, in the long width direction of the second plate portion. On the other hand, at a position where it overlaps with the slit in the overlapped plate portion of the lid plate, while forming a narrow perforated tear portion over the entire length of the overlapped plate portion,
It is characterized in that only the front side plate portion located on the front side of the tear portion in the overlapping plate portion is adhered to the outer surface of the second plate portion.

[0009]

According to the sheet roll storage case of the present invention, a slit for drawing out a sheet is formed in the second plate portion (sheet take-out side plate portion) of the case body, and a narrow perforation is formed at the slit overlapping position in the overlapping plate portion. When the tear portion is torn, the slit is exposed to the outside, and the sheet accommodated in the case body can be pulled out from the slit. In addition, after the tearing portion is torn, the front side plate portion of the overlapped plate portion ahead of the tearing portion is directly adhered to the outer surface of the second plate portion of the case body. Two cardboards are superposed in the bonded area. Further, when the tear portion is cut off, the opening cover plate portion of the lid plate can be opened and closed with respect to the case body, and the opening cover plate portion is opened to slit the unrolling end portion of the sheet roll housed in the case body. You can work to lead to the outside through. Furthermore, after the sheet unwinding end portion is guided to the outside through the slit and the base side plate portion of the overlapping plate portion is inserted inside the second plate portion, the portion has a double wall structure.

[0010]

As described above, according to the sheet roll storage case of the present invention, the sheet take-out side plate portion of the case body is
Since the front side plate part of the overlapping plate part remains adhered to the (second plate part) part and the base side plate part of the overlapping plate part is also applied to the inside of the second plate part, the slit forming part is excluded. The entire area of the second plate portion has a double wall structure, and the second plate portion is reinforced. Further, the front side plate portion of the overlapping plate portion is conventionally discarded, but in the present invention, the discarded front side plate portion can be effectively utilized as a reinforcing member, and the front side plate portion is the sheet roll. Since it is previously bonded to the outer surface of the second plate portion at the time of manufacturing the storage case, there is an effect that no special work for bonding the front side plate portion is required.
