[Technical field to which the device belongs]

 The present invention relates to improvement of a cutter portion of a household or commercial film cutter for thin film-like materials such as wrap film, cellophane tape or kraft tape, and more particularly to a wrap film for food packaging currently on the market.

[0002]

[Prior art]

 At present, thin film materials such as wrapping films for food packaging, cellophane tape, and kraft tape are widely used not only in general households but also for business purposes. With the progress, it is widely used for food preservation.

Conventionally, for example, in the case of a wrap film for food packaging, as shown in FIG. 7, the lap film has a front wall a, a rear wall b, and a side wall c, and a part of the side wall c ′ is openable. It is housed in an empty paper container. A tongue piece e is provided at a front edge portion d of the openable side wall portion, and a cutter f is attached to an end edge of the tongue piece e, and the cutter f allows the tongue piece to be opened from the inside of the container. The wrap film g pulled out through the side wall portion is cut into an arbitrary length.

By the way, a metal blade, particularly a serrated blade, has been conventionally used for the cutter f of many wrap films for food packaging currently on the market. In use, there are safety and usability problems in the following points. That is, it is very dangerous that the user's hand touches the blade when the wrapping film is cut, and the blade is often damaged. In particular, it is necessary to be very careful when handling the infant film or the elderly. This is a matter that should be further emphasized in the future from the viewpoint of complying with the provisions of the PL law (Product Liability Law), which has recently been receiving attention. Also, when collecting waste, it is required to remove metal parts as hazardous materials at each house before discarding used boxes. It should be noted that recent interest in resource recycling has increased. Furthermore, although the product cost of the wrap film itself and the paper part is low, the cost is high because the metal part is purposefully attached to the box housing the wrap film.

As a method for solving the above problems, conventionally, there is a method in which a paper blade is attached to the end edge of the side wall of the box body instead of the metal blade, but it has a difficulty in sharpness and is applied. The possible range is considered to be narrow. There are also improvements that allow the metal blades to be removed when disposing of garbage, but not only is it troublesome to remove them each time, but it is also not practical for restaurants and food processing. It is not realistic from the standpoint of workability when used in large quantities. On the other hand, in the field of cellophane tape and craft tape, the above-mentioned improvements have not been made at present.

[0006]

[Problems to be solved by the device]

 Therefore, the object of the present invention can be applied not only to the wrap film but also to the cutting of cellophane tape, graft tape, etc., and the user's hand may be damaged by touching the blade when cutting them. It is not necessary to remove the cutter before disposing of the used container, and it is not necessary to purposely attach it to the container for storing wrap film etc. It is to provide an improved film cutter capable of

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a front wall, a rear wall, and a plurality of side walls, and a part of the side walls is openable, and accommodates a thin film-shaped material in a roll shape. The thin film material provided on the container and pulled out from the inside of the container through the opening of the side wall is attached to the edge of the side wall so as to cut the thin film-like material to an arbitrary length. In the film cutter, the film cutter is composed of at least one granular abrasive provided on the edge of the side wall.

In one embodiment of the present invention, the abrasive film cutter is formed by applying a mixture of mineral powder, plastic, crushed metal powder or a combination thereof and an adhesive. The abrasive film cutter may be formed by adhering sandpaper with an adhesive.

In another embodiment, the abrasive film cutter can be applied to the cutting of wrap films, cellophane tape, kraft tape or metal foil for food packaging.

[0010]

[Mode for Carrying Out the Invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a case where the film cutter of the present invention is applied to a container for a wrapping film for food packaging as an example. However, it should be understood that the film cutter of the present invention is not limited to the cutting of wrapping film for food packaging, but can also be applied to metal foil, cellophane tape or kraft tape. In this figure, the container for accommodating the wrap film for food packaging is indicated by 1 as a whole. The container 1 is entirely made of paper and has a front wall 11, a rear wall 12, and side walls 13, 14, 15 and 16 as in the conventional case. One of these side walls 14 is openable and provided with an opening 2. Therefore, the roll 3 (FIG. 2) of the food packaging wrap film is taken in and taken out from the container, and the wrap film 31 is provided. It is possible to pull out from inside the container. The open side wall 14 is provided with a tongue portion 142 at its front edge portion 141, and this tongue portion 142 holds the food packaging wrap film 31 in place when the food packaging wrap film 31 is cut. make it easier.

On the side wall 13 on the side overlapping with the tongue portion 142, an end edge portion 131 on the side opposite to the opening portion 2 is made of a granular abrasive material 4 in the form of a band having a width of about 2 mm. A film cutter 5 is attached. The film cutter 5 made of this abrasive material 4 is also attached to the edge portion 161 of the side wall 16 adjacent to the side wall 13, and therefore the film cutter 5 is attached to the edge portions 131 and 161 of the side walls 13 and 16 respectively. It means that they are mounted at right angles next to each other.

The film cutter 5 is made of a mixture of an abrasive and a grinding powder 4 obtained by mixing mineral powder, plastic, crushed metal powder or a combination thereof, and an end portion 131 of the side wall 13 and a side wall 16 adjacent to the end portion 131. It is formed by applying to the edge portion 161.

The abrasive material 4 such as the mineral powder, plastic, crushed metal powder, etc. to which the film cutter 5 is adhered performs the same operation as a conventional metal saw blade to cut the food packaging wrap film 31. That is, when the wrapping film 31 for food packaging is cut, as shown in FIG. 2, the wrapping film 31 for food packaging is pulled out from the container 1 through the opening 2 of the container by a required length and can be opened freely. The tongue portion 142 of the side wall 14 is pressed against the drawn wrap film 31 as shown by the chain double-dashed line in FIG. In that state, the wrap film 31 is brought into contact with the film cutter 5 and is cut at an angle α and pulled. As described above, the film cutter 5 according to the present invention is not a saw blade-shaped film cutter as in the past, but is one in which the abrasive 4 is applied and bonded, so that even if the film cutter 5 is inadvertently touched, The wrap film 31 can be cut more safely than before without damaging the wrap film 31.

FIG. 3 shows an outline of a process of attaching the granular abrasive 4 to the side wall 13 of the container 1 and the side wall 16 adjacent thereto. As shown in (A) of this figure, the container 1 is first cut from a raw paper material into a developed state. Next, mineral powder, plastic, metal crushed powder, or a combination of these abrasives 4 and adhesive 6 are put in appropriate amounts in a container and sufficiently stirred to produce a mixture 7 (B). The roughness of the particles of the abrasive 4 is appropriately selected according to the type of film material to be cut. Fine particles or coarse particles may be used when the film material is a wrap film, but coarse particles are suitable when the film material is a metal foil such as an aluminum foil. Next, the container in the expanded state is placed on a printing line, and the outer surface of the container is subjected to a printing process by a known method. Then, the container in the expanded state is kept on the same line at the end edges 131, 161 of the side walls 13 and 16. The mixture 7 is applied to the surface by a method such as spraying, adhesion roller or brush coating (C). The container in the developed state thus coated with the mixture 7 is assembled by a known method (not shown) after the adhesive of the mixture 7 is cured by infrared irradiation or the like to fix the abrasive 4 to the side wall. Is completed.

Instead of applying the mixture 7 as the film cutter 5, a commercially available sandpaper (sandpaper) is cut into a long thin piece and bonded to the edge portions 131 and 161 of the side walls 13 and 16 of the container 1. Good. Even in this case, the particle size of the sandpaper is determined according to the application.

As described above, the film cutter 5 according to the present invention does not need to specially attach a metal or paper saw blade to the side wall of the container, and can be easily extended on the printing line for a relatively short time as an extension work of the printing process. It can be applied or adhered with, which greatly contributes to cost reduction of the product.

Although the case where the film cutter 5 is attached to the edge portions 131 and 161 of the side walls 13 and 16 of the container 1 has been described above, the attachment of the film cutter 5 is not limited to this position. . For example, as shown in FIG. 4, the abrasive 4 may be applied to the edge 132 of the side wall 13 of the container 1 so as to surround the edge 132, or the film cutter 5 may be formed, or FIG. As shown in FIG. 5, the tip portion 143 may be formed around the tip portion 143 of the tongue portion 142 of the openable side wall 14. As shown in FIG. 6, when applied to a storage container for kraft tape or cellophane tape 8, the saw blade part provided at the tip of the conventional storage container 9 is used as a film cutter 5'according to the present invention. It can be replaced.

[0019]

[Effect of device]

 As described above, according to the present invention, when the film cutter is formed by the granular abrasive provided on the edge of at least one side wall of the container, the film cutter is inadvertently touched. However, the film material can be cut more safely than before without scratching the hands.

Further, it is not necessary to purposely attach a metal or paper saw blade to the side wall of the container, and it is possible to easily apply or bond on a printing line in a relatively short time as an extension work of the printing process, It greatly contributes to product cost reduction.

Furthermore, also in the case of collecting waste, it is not necessary to remove the cutter before the used container is disposed of, and the container can be discarded as it is. Therefore, there is no problem in workability even in places where a large amount of work is used, such as restaurants and food processing.

Further, the film cutter of the present invention can be applied to cellophane tape and craft tape.
