Then, the required amount of the film 200a 'inserted through the slit 206 is pulled out with the other hand, and the film 200a' is reliably cut by being pressed against the cutting blade 207 provided on the lower edge of the side surface of the box body 1 and pulled. . The above-described slit 206 is for maintaining a state in which no wrinkles or unevenness occurs when the film 200a 'is pulled out from the film roll 200a, and cuts the film 203 in a state where the film 200a' is pulled out evenly from the slit 206. This allows the film 203 to be reliably cut.

[Problems to be solved by the invention]

The above-mentioned wrap film storage box 200
Can reliably and easily perform the cutting operation of the film by the guide effect of the film 200a 'by the slit 206. However, some users require that the film 200 be inserted into the slit 206 when starting use.
Many people cut the film drawn out of the opening 202 directly against the cutting blade without inserting a ′. This is because, besides the person who does not read the instructions for use well, there is a person who uses the same way as the conventional storage box because the work of inserting the leading end of the film into the slit 206 is troublesome. In this case, there is no difference from the conventional wrap film storage box, and the meaning of providing the slit is lost.

The present invention has been made in view of the above-mentioned conventional circumstances, and its object is to function similarly to the above-described storage box for a wrapped film with a slit. An object of the present invention is to provide a wrap film storage box that does not require the operation of inserting a film into a slit.

[0011]

In order to solve the above-mentioned technical problems, a storage box for a wrap film for packaging according to the present invention comprises a box body for storing a film roll of a wrap film. The box body has an opening on one side, and one side of the lid is flexibly mounted and supported along one side edge of the opening, and the opening can be opened and closed by the lid. The other side edge of the opening of the box body is cut down by one step to cut out the guide side of the film. The guide side is parallel to the other side edge of the opening, but is notched above the guide side, and the film drawn from the film roll in the opening is loaded and evenly pulled out. Therefore, the guide side is cut out to have a width substantially equal to the width of the film. Further, at both ends of the guide side, notches are formed to hold both ends of the film drawn on the guide side. The holding portion is for holding both ends of the film through the appropriate clearances (the front and back of the film), and the width thereof is such that both ends of the film pulled out from the roll film and drawn on the guide side can be easily formed. Set the width just enough to fit. Further, a cutting blade for applying a film and cutting the film is provided along an edge of the box body facing the guide side with the side surface of the box body interposed therebetween.

When using wrap film for the first time,
The leading end of the film drawn from the film roll is placed on the guide side, and both sides of the film are inserted into the holding portions formed at both ends of the guide side, and the lid is closed. Thus, the film pulled out from the film roll in the box body is held while resting on the guide side. When cutting the film, the drawn-out film is lightly pressed by holding the box body with one hand and closing the lid. Next, the film placed on the guide side is pulled out by a required amount with the other hand, and the film can be cut by pressing against the cutting blade provided on the edge of the box body and pulling. As described above, the film pulled out while being placed on the guide side is pulled out while maintaining uniform tension over the entire width, which can prevent the occurrence of wrinkles and bias, and is pressed against the cutting blade while maintaining the state. Be cut off. In addition, setting the film is as simple as placing the film drawn from the film roll in the box body on the guide side and inserting both ends into the holding parts provided at both ends of the guide side. The film can be guided in the same manner as described above.

According to a second aspect of the present invention, there is provided a storage box for a wrap film, wherein a pressing piece is provided along the other side of the lid to cover a side surface of the box body having a guide side. Therefore, when cutting the film, by holding the box body with one hand and closing the lid, the pressing piece is used to uniformly press the drawn film placed on the guide side from the front side over the entire width, and the same. The guide by the guide side can be assisted. Thereby, the function of pulling out the film while maintaining a uniform tension over the entire width of the film can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show a storage box A for a wrap film embodying the present invention. Storage box A
Is, for example, coated cardboard Yes formed using (550g / m ²⁾ paper material, such as, comprises a box body a substantially prismatic for accommodating the film roll b of the wrap film.

The box body a has an upper surface opened, and one side edge of the lid 2 is integrally and flexibly attached to and supported by one side edge of the opening a1 so that the opening a1 can be opened and closed by the lid 2. are doing. The film roll b is taken in and out of the opening a1 as required. On the other side edge of the lid 2, a holding piece 2a is attached to bendably and supported, and in a state where the lid 2 is closed, the holding piece 2a is attached to the opening a1 on the side surface a 'of the box body a.
It is configured to be pressed onto the guide side 3 provided along the side and to cover this. End pieces 7 for holding both ends of the film roll b are attached to both ends of the opening of the box body 2.

At the edge a2 of the other side of the opening a1 of the box body a, there is provided a notched guide side 3 in which the edge a2 is cut down by one step. The guide side 3 is located at the opening a of the box body a.
A notch is formed below an edge a2 on one side of another portion at an appropriate size, for example, at a position lowered by about 5 mm to 10 mm so as to be substantially parallel to an extension line connecting the edges a2. The guide side 3 is cut out at a width substantially equal to the width of the film roll b stored in the box body a, and the film b pulled out from the film roll b and placed on the guide side 3 is provided at both ends thereof. A holding portion 4 for holding both ends of the 'is formed (FIG. 1).

The holding portions 4 are notches formed in a range between both end portions of the guide side 3 and an edge portion a2 left on the both end portions, and one end (the center side of the box main body) is appropriately opened. A gap having a width is formed (FIGS. 1 and 2). This gap serves as a holding portion 4 for holding both ends of the film b '. When the film b' drawn from the film roll b is placed on the guide side 3, the edges of both ends of the film b 'are held. By holding the film b ′ from above and below by the holding portion 4, the film b ′ is prevented from coming off, and the drawn film b ′ is always held on the guide side 3. still,
It is not necessary that the gap of the above-described holding portion 4 is so narrow as to be in contact with the front and back surfaces of the film b ′ like a slit and hold the film b ′.
For example, a clearance of about 1 mm to 3 mm may be provided.

A projecting piece 6 projecting from both ends of the guide side 3 toward the center of the box body a is formed between the holding portion 4 and the edge a2. The protruding piece 6 is formed as a part of the side surface a 'of the box body a. However, if the width is set to be small, the strength may be weakened. Sufficient strength and durability can be ensured by applying and bonding a reinforcing piece made of paper or synthetic resin. Further, the formation position of the guide side may be changed as appropriate.

Further, along the lower edge of the side surface a 'of the box body a provided with the guide side 3, a cutting blade 5 for pressing and cutting the film b' drawn out while being guided by the guide side 3 is used. Is attached. The cutting blade 5 is made of hard paper or the like impregnated with metal or resin, and has a cutting edge formed in a zigzag shape over its entire length. The cutting blade 5
Attached and fixed along the lower surface of the edge a3 facing the guide side 3 via the side surface a 'of the box body a, and only the cutting edge is
It is configured to protrude from the edge a3.

When using the wrapping film storage box A constructed as described above, the film b 'is pulled out from the film roll b, and the guide side 3 provided on the other side of the opening a1 is used.
, And both sides of the film b ′ are inserted into the holding section 4. As a result, the extracted film b '
Both sides are held while being placed on the guide side 3. Therefore, in normal use, the film b 'is held from above and below by the holding portions 4 on both sides, so that the film b' does not come off on the guide side 3.

When cutting the film, the box body a is held by one hand and the lid 2 is closed, so that the film b 'drawn out as described above is lightly pressed by the pressing piece 2a. Then, the user holds the leading end of the film b 'with the other hand, pulls out the necessary amount as it is, and pulls the film b' by pressing against the cutting edge of the cutting blade 5 exposed on the edge a3 of the side surface a 'of the box body a. 'Is easily disconnected. As described above, when the film b 'is pulled in a state where the film b' is placed on the linearly formed guide side 3, the film b 'is always in contact with the guide side 3, and the film b' By being held in a plane by the pressing force, it is pulled out while maintaining a uniform tension over the entire width. The film b ′ is pressed against the cutting edge of the cutting blade 5 while maintaining the state,
Cut at once. Therefore, the film b 'to be drawn out
There is no wrinkle or uneven factor, and anyone can cut easily and cleanly.

The film roll box main body a that functions as described above has the same guide effect as a conventional storage box with a slit, and is used again from the start of use or from a state where the film is once wound on the film roll. In such a case, the film b 'is pulled out from the film roll b, placed on the guide side 3 as described above, and both ends are inserted into the holding portion 4 to be in a usable state. When the drawn-out film b 'is wound around a film roll b in the box body a and stored, for example, the film b'
The film b 'can be easily opened and wound around the film roll b of the box body a by picking out both ends of the box from both holding portions.

The above-mentioned wrap film storage box A is provided with the pressing piece 2a along the other edge of the lid 2. According to the gist of the present invention, the wrap film shown in FIGS. As in the case of the storage box A2, the opening a1 may be configured to be freely openable and closable only by the lid 20 without providing the pressing piece. The storage box A2 does not cover the film b 'in contact with the guide side 3 with the pressing cover, but presses the film roll b in the opening a1 with the lid 20, that is, the state in which the film b' is pressed.
The film b 'can be pulled in and cut while maintaining the state in which the film roll b does not rotate in the box body a.

This makes it possible to apply a relatively strong tension to the drawn-out film b ′ when cutting the film by pressing it against the cutting blade 5. It can be done simply and reliably. Further, since the lid 20 of the box body a2 can enter the opening a1 and press against the outer peripheral surface of the film roll b even if the outer diameter of the film roll b decreases with use, The function of preventing rotation of the film roll b is stably exhibited until the film is used up.

Although the storage boxes A and A2 of this embodiment are made of paper material such as coated cardboard, the storage box of the present invention has a structure similar to that of the storage box described above. A hard synthetic resin plate having a thickness, for example, a thickness of 0.2 mm to 2.0 mm
It may be constituted by using a synthetic resin plate of polypropylene or the like of about mm (not shown).

[0026]

Since the wrap film storage box of the present invention is constructed as described above, when the wrap film is used for the first time, the leading end of the film drawn from the film roll is placed on the guide side. With the simple work of inserting and inserting both ends into the holding parts formed at both ends of the guide side, while holding the film drawn from the film roll on the linear guide side,
The film can be pulled out. Therefore, the storage box of the wrap film of the present invention has the same guide effect as the conventional storage box configured to insert the film through the slit, maintains uniform tension over the entire width of the drawn film, and has a cutting blade. Can be cut reliably.
Also, when setting the drawn film on the guide side, it can be used simply by inserting both sides of the film into the holding parts provided at both ends of the guide side, it is troublesome to set the film and uses the guide function by the guide side The absurdity that the user who does not come out can be avoided.

In the storage box for a wrap film according to the second aspect of the present invention, a holding piece is provided along the other side of the lid so as to cover the side surface of the box body having the guide side. At this time, by holding the box body with one hand and closing the lid, the holding piece presses the film drawn on the guide side almost uniformly over the entire width from the front side and assists the guide by the guide side. can do. As a result, the function of pulling out the film while maintaining uniform tension over the entire width of the film can be improved, and as a result, the film can be more reliably and easily cut.
