Incidentally, as described above, the fixing means for fixing the stationary portion 44 to a predetermined position on the one side surface a2 of the box body a may be an adhesive such as hot melt, a double-sided tape, or a fastener such as a stapler.

By the way, the compatible piece 4a of the above-mentioned knob piece 4
The edge corresponding to the cutting blade 3 side is formed obliquely, as shown in FIG. The inclined portion 46 prevents the pulled-out film b ′ from being strongly pressed against the standing piece 4a and piercing the film b ′ when the pulled-out film b ′ is pressed against the cutting blade 3 to be cut. This is to ensure that the film b ′ can be cut without any trouble.

Next, a method of using the wrapping film storage box A configured as described above will be described. The storage box A configured as described above has the cutting member 2 at the distribution stage.
Since 0 is adhered to one side surface a2 of the box body a, the cutting member 20 is peeled off from the box body a when first used. Since the paper material 40 which will be the tab 4 is punched out from the cutting member 20 removed from the box body, this paper material 40 is removed. Then, the valley portion 41 and the mountain portion 42 of the paper material 40 are bent as described above to make the tab 4. The knob 4 is a box body a and one side surface a2.

Assemble the tab 4 '(Fig. 6-
b). Since the above-mentioned knob 4'has the fixing surface 50 of the stationary portion 44 fixed by adhesive or double-sided tape or the like, it is securely fixed and prevents the trouble that the knob 4'falls off during use. be able to.

After the knob 4 (4 ') is attached as described above, the leading end of the film b'drawn from the film roll b through the opening a1 is pulled out onto the one side surface a2.
In this way, by pulling out the film b ′ while being sandwiched between the holding piece 2 and the one half of the side surface a2 of the box body a, the film b ′ is pulled out uniformly over the entire width, and extra wrinkles are twisted. Can be prevented.

After the film b'is pulled out as described above, the film b'is pressed against the cutting blade 3 to cut the starting end of the film b '. In this state, the cut edges of the cut film b ′ are linearly placed along the cutting blade 3. When the film b ′ is pressed against the cutting blade 3 for cutting, the tab 4 is pressed against the film b ′. However, as described above, the cutting blade 3 of the picking piece 4
Since the edge corresponding to the side is provided with the inclined portion 46 formed in an inclined shape, when the film b ′ is pressed against the cutting blade 3 and cut, the film b ′ may be pierced to hinder the cutting of the film b ′. Can be prevented.

On the other hand, when the pulled-out film b'is cut, only the central portion of the film b'is pushed up by the knob 4 and bulges into a substantially chevron shape. Therefore, when cutting the film b ′ from the next time onward, it is easy to pick up the cut edge of the film b ′ in a swollen state by inserting a finger between the standing pieces 4a of the picking piece 4, and from this state, the film b ′ is cut. 'Can be pulled out and pressed against the cutting blade 3 for cutting. That is, because of the function of the gripping piece 4, the cutting edge of the film b ′, which easily adheres to the cutting blade 3 or the one side surface a2 of the box body a, can be easily gripped, and the cutting operation of the film b ′ can be performed smoothly. is there.

In the above-described embodiment, the tab piece 4 is made by assembling the paper material 40 in which the tab piece is punched out in a part of the cutting member 20, and is inserted and fixed in the notch 45 of the box body a. However, in the above-mentioned picking piece, what if the cut edge of the cut film b ′ can be raised in a substantially chevron shape and the raised film b ′ can be picked by inserting a finger from between the compatible pieces. It may take a form. For example, a piece of hard paper similar to the above-mentioned pick is stored inside the box main body a, and when opened, the box main body a
It may be used by inserting it into the notch 45 (not shown). Further, the knob may be attached to and fixed to the box body from the beginning so that the user can immediately use it without having to assemble the above-mentioned knob at the start of use.

Next, the wrapping film storage box A2 shown in FIGS. 7 and 8 will be described. This storage box A2 is a box body a
The edge a20 on the other side of the opening a1 is provided with a guide side 30 formed by cutting out the edge a20 by cutting it down one step. The guide side 30 has an appropriate dimension below the edge a20 on the other side of the opening a1 of the box body a, for example, 5 mm to 10 mm.
A notch is formed at a position lowered by about mm so as to be substantially parallel to the extension line connecting the edges a20. The guide side 30 is notched so as to have a width substantially the same as the width of the film roll b accommodated in the box body a, and the film b placed on the guide side 30 is pulled out from the film roll b at both ends thereof. '
A sandwiching portion 34 for sandwiching both end portions of is formed (FIG. 7).

The both sandwiching portions 34 are notched in the range between both end portions of the guide side 30 and the edge portion a20 left on the both end portions, and have an appropriate width with one end (center side of the box body) open. The gap is formed. This gap serves as a sandwiching portion 34 for sandwiching both ends of the film b ′, and when the film b ′ pulled out from the film roll b is placed on the guide side 30, the edges of the film b ′ are sandwiched. Then, by sandwiching the film from above and below by the sandwiching portion 34, the film b'is prevented from coming off, and the pulled-out film b'is always held on the guide side 30. The above-mentioned gap of the sandwiching portion 34 has an appropriate dimension, for example, 1 mm to 3 mm.
It is advisable to provide a clearance of about mm.

Further, projecting pieces 36 projecting from both ends of the guide side 30 toward the center of the box body a are formed between the sandwiching portion 34 and the edge portion a20. The protrusion 36 is formed as a part of the side surface a2 of the box body a, but if the width is set to be narrow, the strength may be weakened. Sufficient strength and durability can be secured by applying and adhering a reinforcing piece made of or synthetic resin. The formation position of the guide side may be changed appropriately.

When the wrapping film storage box A2 constructed as described above is used, the film b'is pulled out from the film roll b and placed on the guide side 30 provided on the other side of the opening a1, and the film b Both sides of 'are inserted into the holding portion 34. As a result, the film b ′ that has been pulled out
Both sides are held while being mounted on the guide side 30.
Therefore, in normal use, the film b ′ is sandwiched from both sides by the sandwiching portions 34 from above and below, so that it does not come off from the guide side 30.

When cutting the film, the box body a is held by one hand and the holding piece 2 is pushed from above,
The film b ′ pulled out as described above is lightly held by the holding pieces 2. Then, by holding the tip of the film b ′ with the other hand, pulling out the required amount as it is, and pressing and pulling against the cutting edge 3a of the cutting blade 3 exposed at the corner side a3 of the one side surface a2 of the box body a, The film b'is easily cut. As described above, the guide side 3 formed linearly
When the film b ′ is pulled while being placed on 0, the film b ′ is always in contact with the guide side 30 and is planarly held by the pressing force of the sandwiching piece 2, so that the film b ′ is evenly distributed over the entire width. It is pulled out while maintaining tension. The film b ′ is pressed against the blade edge 3a of the cutting blade 3 while maintaining the state, and is cut at one time. Therefore, there is no cause of wrinkles or unevenness in the drawn-out film b ′, and anyone can easily and neatly cut it.

Incidentally, the knob piece of the present invention is integrally formed by using a synthetic resin like the knob piece 4 '' shown in FIG. 4, and like the above-mentioned knob piece 4, the mounting portion of the box main body a is attached. It may be attached and fixed to. Also, as for the mounting structure of the knob, any existing structure may be used as long as it can securely fix the knob, and for example, a pin-shaped object may be inserted into the round hole instead of the insert piece. Further, the stationary portion 44 may be attached and fixed to the central portion of one side surface a2 of the box body a by using a double-sided tape, stapler, or glue. Note that the position where the above-mentioned knob is provided is not limited to the central portion of the box body, and it may be provided at a position slightly displaced from the central portion of the box body.

Although the storage boxes A and A2 of this embodiment are made of a rigid paper material such as coated cardboard, the storage box of the present invention has the same structure as the storage box. , A hard synthetic resin plate having an appropriate thickness, for example, a thickness of 0.2
A synthetic resin plate such as polypropylene having a size of about mm to 2.0 mm may be used (not shown). By the way, the wrapping film storage box of the present invention is most preferably used for commercial use with a film of about 100 m, but it can also be used for household use with a small number of windings.

[0029]

As described above, the wrapping film storage box of the present invention is provided at a position close to the cutting blade provided along the side opposite to the opening on one side of the box body. By arranging a plurality of standing pieces in parallel at a predetermined interval, a knob piece that is close to the cutting blade is provided. Therefore, when the film is pulled out and pressed against the cutting blade and cut, a part of the cutting edge of the wrap film that is about to adhere to one side surface of the storage box main body is protruded by the knob, and only that part is substantially cut. It can be heaped up in Yamagata. Therefore, when using the wrap film next time, it is possible to pull out the film easily by inserting a finger from between the compatible pieces of the picking pieces, picking up the cutting edge of the film that rises in a substantially chevron shape, and reliably. Become. Therefore, like the conventional one, when pulling out the edge of the film, the edge of the film is broken when picking the cutting edge of the film, and the films adhere to each other,
It is possible to prevent the film from being wasted because the film is crunchy or the film which is irregularly folded is caught by the cutting blade. As a result, the film can be used to the end without waste.

Since the wrapping film storage box according to the second aspect of the present invention is provided with the holding portions at both ends of the guide piece, when the wrapping film is used for the first time, the leading end of the film pulled out from the film roll is used. With the simple work of placing it on the guide side and inserting both ends into the sandwiching part formed at both ends of the guide side, with the film drawn from the film roll placed on the linear guide side. The film can be pulled out while holding it. Therefore, the film can be reliably cut by the cutting blade while maintaining the uniform tension over the entire width of the drawn film. Also, when setting the pulled-out film on the guide side, it can be used by simply inserting both sides of the film into the sandwiching portions provided on both ends of the guide side, and the setting of the film is very easy. Furthermore, when pulling out the film, you can pull out by pulling the edge of the film that has been lifted by the picking piece, so there is no need to peel the film stuck to the side of the storage box and pick up the film. , A series of operations for cutting with a cutting blade can be easily performed.

In the wrapping film storage box according to the third aspect of the present invention, since the punching line forming the outer shape of the picked piece is formed in the range of the cutting member in the above box body, the box is first used. It is possible to remove the unnecessary cutting member from the main body, (or peel it off) to pull out the knob, fold it into a predetermined shape to create a predetermined shape, and attach it to the installation site on one side of the box body. By using an unnecessary cutting member, the knob can be easily made, and the waste of resources can be eliminated as much as possible.

In the wrapping film storage box according to claim 4, a stationary portion is set at a predetermined portion within the inner range of the punching line, and the stationary portion is provided with a fixing means at a mounting portion of the knob on one side of the box body. Since it is constructed by using the fixed part, the pick-up piece with the fixed part fixed is pulled out along the punching line, and by bending the predetermined part of this pick-up piece, the pick-up piece can be easily assembled and bonded. The picking piece can be reliably fixed by a fixing means such as an agent or a double-sided tape, and it is possible to prevent a problem that the picking piece falls off during use. Further, since the knob piece is fixed to the storage box by the fixing means, it cannot be accidentally lost before use.

In the wrapping film storage box according to the present invention, the knob is formed of synthetic resin or the like, and the knob is attached to one side of the box body at a mounting position. A knob similar to the one described above can be installed only by attaching the knob configured in a shape to a predetermined position on one side surface of the box body. Further, when the knob piece is made of synthetic resin, it is excellent in strength and durability and looks good in design.

In the wrapping film storage box according to the sixth aspect, since the cutting blade side of the compatible piece of the picking pieces configured as described above is inclined and inclined, the film pulled out is broken by the standing piece. Can be avoided. As a result, when the cutting edge of the film that rises in a substantially mountain shape is picked up by the picking piece and is pressed against the cutting blade of the storage box to cut, the inclined part facing the cutting edge of the compatible piece contacts the film. However, it is possible to avoid the problem that the film is forcibly abutted and cut forcibly, and the film can always be cut reliably.
