BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an approximately saw blade-shaped cutting member for accommodating a food packaging wrap film or the like wound in a roll shape and cutting a wrap film drawn out of a case by a predetermined length. The present invention relates to a wrap film storage case provided with:

[0002]

2. Description of the Related Art Conventionally, as a wrap film housing case as described above, for example, one described in Japanese Utility Model Publication No. 61-22823 is known. As shown in a perspective view of FIG. 9 and an enlarged sectional view of a main part of FIG. 10, the conventional wrap film storage case has an opening 53 of a case body 52 that rotatably stores a wrap film 51 wound in a roll shape. A lid 54 that covers the opening 53 is connected to one side edge of the opening 52. The tip of the lid 54 overlaps the front plate 52 a of the case main body 52 and has an opening 5.
3 is pulled out of the front side plate 5
2a is connected with the cover piece 55 which can be sandwiched by the cover piece 5a.
A cutting bracket 56 is attached to the inner surface side front end edge of 5,
The cutting metal fitting 56 has a structure having a saw blade 56 a at the tip edge thereof slightly projecting from the tip edge of the cover piece 55. The saw blade 56a of the cutting bracket 56 is a straight line parallel to the bottom 52b of the case body 52, and
As shown in the figure, the cover piece 55 and the front side plate 52a protrude in a direction parallel to the facing surface.

[0003] Since the conventional wrap film accommodating case is configured as described above, the opening 53 of the case main body 52 is provided.
The wrap film 51 pulled out from is cut as follows. Note that, for convenience of explanation of the cutting action, as shown in FIG. 11, three-dimensional right-angle coordinates are displayed for the storage case. In the rectangular coordinates, the X axis is an axis perpendicular to the surface of the front side plate 52a, the Y axis is an axis along the longitudinal direction of the front side plate 52a, and the Z axis is an axis along the depth direction of the front side plate 52a. It is.

Therefore, in order to cut the wrap film 51 pulled out from the opening 53 of the case main body 52, the substantially central portion of the cover piece 55 is moved in the direction of the front plate 52a (X axis ( The base of the wrap film 51 pulled out by pressing in the −) direction is sandwiched and fixed between the front side plate 52a and the cover piece 55, and in this state, the tip end of the wrap film 51 pulled out is right-handed. While pulling slightly in the pull-out direction (X-axis (+) direction), push down the end of the storage case in the Y-axis (+) direction in the Z-axis (-) direction, and hold the right hand holding the tip of the wrap film 51. By applying a twisting operation such as lifting in the Z-axis (+) direction, the wrap filler pulled out by the saw blade 56a of the cutting fitting 56 attached to the tip edge of the cover piece 55 is drawn. The accommodating case 51 at the distal end portion position of the Engai piece 55 Y-axis (+) was supposed to disconnect from direction end portion.

[0005]

However, in the conventional wrap film accommodating case, as described above, when the drawn wrap film 51 is cut,
In addition to pushing down the end of the accommodation case in the Y-axis (+) direction in the Z-axis (-) direction, a twisting operation is performed such that the right hand holding the leading end of the wrap film 51 is lifted in the Z-axis (+) direction. Otherwise, the wrap film 51 cannot be cut well, and therefore, the operation is troublesome, and the wrap film 51 cannot be cut well and often fails, and the cut wrap film 51 is spread in a planar state. Has been difficult to maintain.

[0006] This is because, as shown in FIG. 10, the saw blade 56a of the cutting bracket 56 in the conventional wrap film accommodating case moves in the Z-axis (-) direction parallel to the opposing surfaces of the cover piece 55 and the front side plate 52a. When the wrap film 51 is cut, the saw blade 56
a comes into contact with the surface of the wrap film 51 drawn out to the XY plane at a right angle.
By simply pulling the saw blade 1 in the X-axis (+) direction, the saw blade 56a only moves relatively in parallel along the plane of the wrap film 51.
a, it is difficult to bite in the initial state.
Is formed in a straight line parallel to the bottom side 52b of the case main body 52, so that the saw blade 56a comes into line contact with the wrap film 51, and the biting force extends over the entire length of the wrap film 51 in the width direction. Is dispersed, so that the initial biting of the saw blade 56a into the wrap film 51 becomes more difficult.

Further, the saw blade 56a of the cutting fitting 56
Is formed by cutting with a saw blade-shaped cutter. When the blade edge portion is enlarged, it is not sharpened toward the blade edge direction as shown in FIG. The cut surface by the blade exists only for the thickness of the plate (about 0.2 mm), and this causes the initial biting of the saw blade 56a into the wrap film 51 to be more difficult.

Therefore, as means for improving the initial biting of the saw blade 56a into the wrap film 51, as described above, the end of the housing case in the Y-axis (+) direction is pushed down in the Z-axis (-) direction, It is necessary to add a troublesome twisting operation such as lifting the right hand having the tip of 51 in the Z-axis (+) direction (see FIG. 11).

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. The cutting operation of the drawn wrap film is simply performed in the horizontal direction (X) without twisting or applying a large force. The wrap film can be cut easily and smoothly simply by pulling lightly on the axis (+) direction.
Accordingly, it is an object of the present invention to provide a wrap film storage case that can maintain the cut wrap film in a state of being spread in a plane.

[0010]

A lid covering the opening is connected to one side edge, and at the tip of the lid, the wrap film that is overlapped with the front plate of the case main body and pulled out from the opening of the case main body can be held by the front plate. In a wrap film storage case provided with a cutting member having a substantially saw-toothed edge at the tip edge of the cover, a substantially saw-toothed edge of the cutting member is formed of a wrap film. A plurality of at least one protruding blade edge portion protruding from the other portion in the blade edge direction at predetermined intervals with respect to the width direction line is formed.

With this configuration, when cutting the wrap film, only the protruding cutting edge portion protruding from the other portion of the cutting member toward the cutting edge first comes into contact with the wrap film surface. The initial biting of the protruding blade tip can be performed very easily. Therefore, it is possible to easily and smoothly cut the wrap film simply by pulling lightly in the horizontal direction without twisting or applying a large force to the cutting operation of the drawn wrap film, The cut wrap film can be maintained in a state of being spread in a plane.

According to a second aspect of the present invention, there is provided the wrap film accommodating case according to the first aspect, wherein the substantially saw-toothed cutting edge of the cutting member has a wavy shape or a zigzag shape along the width direction line of the wrap film. By being formed, a plurality of at least one protruding cutting edge portion is formed at predetermined intervals with respect to the width direction line of the wrap film to protrude from other portions in the cutting edge direction.

According to a third aspect of the present invention, in the wrap film accommodating case according to the first or second aspect, at least the protruding edge of the substantially saw blade-shaped edge of the cutting member is connected to the front plate. It was configured to be inclined toward the direction. With this configuration, at the time of cutting the wrap film, at least the protruding blade tip portion inclined toward the front side plate direction is in a direction opposite to the drawing direction than in a state perpendicular to the drawn wrap film surface. Since the wrap film comes into contact with the wrap film in an inclined state, the initial bite of the protruding cutting edge portion into the wrap film is more easily performed.

According to a fourth aspect of the present invention, there is provided a wrap film accommodating case, wherein a lid for covering the opening is connected to one side edge of the opening of the case body for rotatably accommodating the wrap film wound in a roll shape. At the front end of the body, a cover piece that overlaps with the front side plate of the case body and that can hold the wrap film drawn out from the opening of the case body with the front side plate is connected. In a wrap film storage case provided with a cutting member having a saw-toothed edge, a substantially saw-toothed edge of the cutting member is formed by cutting a plate material for forming the cutting member with a saw-toothed cutter. The cutting surface of the substantially saw-toothed edge is cut in an inclined manner with a saw-toothed cutter so that the front plate side edge of the substantially sawtoothed edge is acute and the one side edge of the cover is obtuse. The configuration was adopted.

With this configuration, when cutting the wrap film, the front plate side edge formed at an acute angle in the substantially saw blade-shaped cutting edge of the cutting member functions as a sharp cutting edge and is drawn out. Since the sharp cutting edge comes into contact with the wrap film in a state inclined in the direction opposite to the drawing direction from the state perpendicular to the wrap film surface, the front plate side edge formed at this acute angle with respect to the wrap film The initial digging becomes very easy, and therefore the cutting operation of the drawn wrap film can be performed without twisting or applying a large force.
The wrap film can be easily and smoothly cut by simply pulling lightly in the horizontal direction, so that the cut wrap film can be maintained in a flat spread state.
