Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrap film for accommodating a wrap film for food packaging wound in a roll shape and a cutting member capable of cutting a wrap film drawn out of a case by a predetermined length. Regarding the storage case.

[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. In this conventional wrap film storage case, a lid that covers the opening is connected to one side edge of the opening of the case body that rotatably stores the wrap film wound in a roll shape. A cover piece that overlaps with the front side plate of the case body and can clamp the wrap film drawn out from the opening of the case body with the front side plate is connected, and a substantially saw-tooth-shaped cutting bracket is provided at a tip edge of the cover piece. Is attached.

In order to cut the wrap film pulled out from the opening of the case main body, the wrap film pulled out by pressing the central portion of the cover piece toward the front plate with the thumb of the left hand holding the housing case. The base of is sandwiched between the front side plate and the cover piece and fixed, and in this state,
With the leading end of the wrapped film pulled out slightly with the right hand in the pull-out direction, the housing case is twisted slightly clockwise and pulled in the direction of the rear plate, thereby forming a saw-toothed shape attached to the leading edge of the cover piece. The cutting bracket allows the drawn-out wrap film to be cut at the position of the leading edge of the cover piece.

[0004]

However, in the conventional wrap film accommodating case, as described above, when the drawn wrap film is cut, the base of the wrap film is moved between the front side plate and the cover piece. Since it is necessary to sandwich and fix it, the tip of the wrap film is in close contact with the cover piece, and it is extremely difficult to take the tip of the wrap film when pulling out the wrap film next time There was a problem. In particular, in the actual marketed products, in order to prevent rewinding of the cut wrap film, a material that adsorbs the wrap film to a part of the outer surface of the front side plate, such as laminating a plastic film, Since the plastic latex or solution is attached in a concentrated manner to form a highly smooth adsorption surface, the tip of the wrap film is more likely to be in close contact with one side of the cover, which captures the tip of the wrap film. Making it more difficult

The present invention has been made in view of the above-mentioned conventional problems. In connection with the opening operation of the lid when the wrap film is pulled out from the opening of the case body, the leading end of the wrap film is moved. It is an object of the present invention to provide a wrap film storage case that can be easily taken.

[0006]

According to a first aspect of the present invention, there is provided a wrap film accommodating case according to the present invention, wherein a wrap film wound in a roll is rotatably accommodated. 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 in which a plurality of cover pieces are connected and a substantially saw-tooth-shaped cutting member is provided at the front edge of the cover piece, an arbitrary part near the front edge on the inner surface side of the cover piece overlapping the front side plate. At the position, a suction surface or an adhesive surface for forming a front-end photographing portion is formed near the front-end edge of the wrap film cut by the cutting member to form a front-end photographing portion. At the outer surface of the front plate that overlaps with the suction surface for forming the leading edge capturing portion or the adhesion surface for forming the adhesive surface, the suction surface for preventing the wrap film from rewinding at a position shifted in the opening edge direction of the front plate or the width direction of the wrap film. Alternatively, the configuration is such that an adhesive surface is formed.

[0007] With this configuration, when cutting out the wrapped film that has been pulled out, the suction surface or the adhesive surface for preventing rewinding formed on the front side plate, and the leading end imaging portion formed on one side of the cover can be formed. Then, when the lid is opened to pull out the wrap film from the opening of the case body, the wrap film will be sucked or adhered to the adhesive surface. While the front end of the wrap film adsorbed or adhered to the surface or the adhesive surface side is about to be pulled back toward the opening while being separated from the front side plate, the wrap film is prevented from being rewound by the suction surface or the adhesive surface for preventing the front side plate from rewinding. Due to the unwinding-preventing action, the leading end of the wrap film is raised from the surface of the front side plate, thereby forming a photographing portion. Therefore, in conjunction with the opening operation of the lid when the wrap film is pulled out from the opening of the case body, the leading end of the wrap film can be easily taken.

According to a second aspect of the present invention, there is provided the wrap film accommodating case according to the first aspect, wherein the suction surface or the adhesive surface for forming the leading end photographing portion of the wrap film is located at the center in the width direction of the wrap film. The wrap film is formed such that the wrap film has a suction surface or an adhesive surface for preventing unwinding at least near both ends in the width direction of the wrap film.

According to a third aspect of the present invention, there is provided the wrap film accommodating case according to the first aspect, wherein the suction surface or the adhesive surface for forming the leading end photographing portion of the wrap film is located at the center in the width direction of the wrap film. The wrap film is formed with the unwinding-preventing suction surface or the adhesive surface at least near both ends in the width direction of the wrap film and at a position near the opening edge of the front side plate in the width direction central portion of the wrap film. Configuration.

According to a fourth aspect of the present invention, there is provided the wrap film accommodating case according to any one of the first to third aspects, wherein the suction surface or the adhesive surface for forming the leading edge photographing portion is in contact with the front side plate of the cutting member. Is formed on the opposing surface of. With this configuration,
Prior to assembling into the wrap film storage case, the cutting member can be formed with a suction surface or adhesive surface for forming the leading edge portion without any change to the conventional manufacturing and assembly process. An adsorbing surface or an adhesive surface for forming a photographing portion can be formed.

According to a fifth aspect of the present invention, there is provided the wrap film accommodating case according to the fourth aspect, wherein the flatness of the surface of the cutting member facing the front plate is such that the lap film is attracted and lifted. The surface facing the front side plate of the cutting member was formed as a suction surface for forming a leading end photographing portion of the wrap film by forming the surface of the cutting member on a smooth surface having a high degree. With this configuration, it is possible to form the suction surface for forming the leading-end imaging portion without making any changes to the conventional manufacturing and assembling processes.

According to a sixth aspect of the present invention, there is provided the wrap film accommodating case according to the fifth aspect, wherein the plane roughness of a surface of the cutting member facing the front plate is defined in JIS B0601. The roughness was 0.2 μm or less. With this configuration,
With extremely high probability, the wrap film can be attracted to the cutting member to form a photographing portion.
