Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a wrap film cutting device for cutting wrap films that wrap foods such as liquid petroleum products and fish meat.

<Prior Art> A conventional wrap film cutting device of this kind will be described with reference to FIG.

The case body 2, which is made of cardboard or the like and which freely rotatably stores the wrap film 1 wound into a cylindrical shape, has a saw-shaped cutter 3 at the upper end of one side wall, with the cutting edge protruding from the open surface that is opened and closed by the top cover. is installed and configured.

After pulling out the tip of the wrap film 1 from the open surface, the wrap film 1 is cut by applying it to the cutter 3 at an arbitrary length position, thereby wrapping the object as a wrap film of a desired size. It is intended for use. For this reason, such a wrap film cutting device is useful not only when storing foodstuffs such as fish meat separately, but also when measuring the sulfur content of liquid petroleum products using a fluorescent X-ray device. It is easily used over a wide range of applications, such as when packaging petroleum products.

<Problems to be solved by the invention> By the way, when cutting the wrap film,
Since the length of the wrap film is cut to an appropriate length by the user's can, there are cases where the wrap film is too short and cannot wrap the object well, or on the other hand, it is too long and the wrap film is wasted. It was a lot.

The present invention was developed in light of these circumstances, and aims to eliminate waste of wrap film and improve usability by allowing users to easily judge and cut the length according to their intended use. It is something to do.

<Means for solving the problem> For this reason, the present invention has been developed by making intermittent cuts in the case body of the wrap film cutting device, and by cutting off the cuts, it is possible to cut the wrap film from one end of the case body in the direction of pulling out the wrap film. A length measuring member is formed which extends to identify a predetermined length from the leading edge of the wrapped film to the cut edge.

<Function> As a result, after the leading end of the wrap film is pulled out from the case body, the wrap film can be easily cut at a desired length position while determining the pull-out length using the length measuring member. Further, the length measuring member can be formed only by making a notch in the case body, which is advantageous in terms of manufacturing cost and reliability.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. Note that the same reference numerals are given to the same components as in the conventional example to simplify the explanation.

In FIG. 1 showing one embodiment, the wrap film cutting device 10 has two side walls of a case body 2 made of cardboard to which a cutter 3 is attached, formed by overlapping two sheets, and an intermittent cutter below the cutter 3 on the outer side. A notch 2a is made. 2 constituting the one side wall
The outside portion of the cardboard sheet surrounded by the notch 2a is glued to ensure sufficient strength to suppress deformation when the wrap film 1 is cut, making it easy to cut.

The cut 2a has two sides parallel to the cutter 3 as shown in the figure, and one end (the left end in the figure) is bent and connected to each other, and the other end has only half cut from the top side to the bottom side. ing. Also,
There is a straight crease 2 in the middle of the two sides of the notch 2a.
b is included.

When in use, the notch 2a is cut off and the upper part is bent inward along the crease 2b, so that the end edge of the wrap film 1 extends from one end of the case body 2 in the direction of pulling out the wrap film 1, as shown in FIG. A length measuring member 4 is formed to identify a predetermined length from the cut edge to the cut edge.

After use, the claw portion 4c formed by cutting off the bent cut portion at the end of the length measuring member 4 is inserted from the opening after cutting off the cut 3a of the case body 2.
Since it is inserted into a gap in a heavy wall and locked, it does not get in the way.

Furthermore, since the length measuring member 4 can be formed only by the notch 2a made in the case body 2 without any special preparation, the manufacturing cost can be kept as low as possible compared to the case where a separate member is fixed. is,
There is no fear that the fixation will come off, and it is also excellent in terms of reliability. At this time, the length-measuring member 4 is bent so as to overlap two sheets, so the strength is increased, and the proximal end side of the length-measuring member 4 is connected to the portion 4a extending from the wall 2a. Part 4 that contacts the side wall
b, the length measuring member 4 itself is difficult to bend.

According to this configuration, when the wrap film 1 is drawn out and cut, the length measuring member 4 is positioned along the drawn out wrap film 1, so that the wrap film 1 can be cut while visually checking the length measuring member 4. Therefore, a wrapped film 1 of approximately a predetermined length can be easily obtained.

Therefore, by obtaining the wrap film 1 with the optimum length to wrap the object to be packaged, it is possible to prevent as much as possible the situation in which it is impossible to wrap the wrap film 1 due to being too short, and the occurrence of waste of the wrap film 1 due to being too long.
Usability can be improved.

Note that the length measuring member 4 may display the actual dimensions, for example, as a ruler, or may display dimensions at 5 cm intervals, and furthermore, the color of the length measuring member 4 may be changed, for example, every 10 cm. In particular, it may be made more convenient for the user.

<Effects of the invention> As explained above, according to the invention, a length measuring member is provided in the case body to identify the length of the pulled-out wrap film, and the wrap film can be cut at a desired length position. A wrapped film of a predetermined length can be easily obtained, waste of wrapped film can be eliminated, and the usability of the wrapped film cutting device can be improved.

Furthermore, since the length measuring member is formed by a cut in the case body, manufacturing costs can be kept as low as possible, and reliability is also excellent.
