Description

[Detailed description of the invention] This invention supports rotatably a roll of film with perforations or cut lines in the transverse direction in advance within a box-shaped container.
The present invention relates to a film cutting device that cuts the film into a predetermined length using a film perforation cutting means provided in a film drawer portion of a box-shaped container while drawing out an end portion of a rolled film.

In strings, a cut line refers to any shape of a cutting hole other than a so-called perforation.

Conventionally, films made of polymers or copolymers such as vinyl chloride, vinylidene chloride, butadiene, and ethylene have been widely used in stores and at home as packaging films for foodstuffs, etc. These rolls of film, with or without film, are stored in a box-shaped container, and cut into a predetermined length or arbitrary length using a cutting means (e.g., protrusions or saws) provided in the film drawer of the container. A film storing and cutting device is known.

However, such portable conventional devices
Normally, one hand holds (or holds) the box and the other hand pulls out the film while cutting it, which can result in the film not being cut in a straight line or the cut films sticking together and becoming wrinkled. There was a problem.

Therefore, the object of the present invention is to
Easily fix to a table, wall, etc. and use both hands to cut a predetermined length of film along the perforation or cut line, so that the edges of the remaining film are in a state where it is easy to pull out the next film. It is an object of the present invention to provide a film cutting device capable of beautifully and reliably wrapping a packaged object with a correctly cut and cut film.

According to the present invention, in a film cutting device that cuts a rolled film having perforations or cut lines in the transverse direction to a predetermined length from a storage container and then takes it out, the cutting device has a top cover that can be opened and closed. A supporting part that rotatably supports the rolled film is attached to the main body, and a supporting part that supports the rolled film in a rotatable manner, and a support part that guides the drawn film when pulling out the end of the rolled film and guides the film along the transverse perforation or cut line. and at least two elastic suction cup mounting holes for fixing the main body to an arbitrary plane rearward from the center of gravity of the bottom plane of the main body,
The cutting means is characterized in that the lateral width of the main body is formed from a tip at the central part of the main body and a film drawer guide surface that slopes downward substantially symmetrically from the tip and becomes wider as the slope increases. A film cutting device is provided.

Hereinafter, preferred embodiments of the film cutting device of the present invention will be described with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a film cutting device 10 according to the present invention has a main body 1 equipped with an upper lid portion 11 that can be opened and closed.
2, which guides the pull-out film when pulling out the end of the rolled film stored in the main body at the joint with the front upper lid part 11 of the main body 12, and also guides the film along the transverse perforations or cut lines. A cutting means 13 for cutting along is configured.

On the other hand, as shown in FIG. 2, the inside of the film cutting device 10 constitutes a space for storing a roll film wound around a cylindrical hollow core, and both end surfaces of the main body 12 and the upper lid part 11 are provided with the circular shape. An arcuate recess 14 (roll film support) is provided to rotatably support both ends of the columnar core.

Note that instead of being supported by the recess 14, for example, two parallel idle rollers may be provided inside, and the roll film may be placed on these.

The cutting means 13 has a pointed end 15 at the center of the warp and a pointed end 1.
5 and a film drawer guide surface which is preferably symmetrically inclined and becomes wider as the inclination increases, and when the film 16 is pulled as shown in FIG. 3, the main body 12 is formed as shown in FIG. The roll film 17 housed inside the film rotates smoothly by the force of pulling out the film 16, and the film 16 is pulled out, and when the perforations or cut lines 18 made in advance at predetermined lengths come into contact with the tip 15, the film is cut by the perforation machine. The pieces are sequentially cut from the center along the cut line 18, as shown in FIG.

In this way, a predetermined length of film is cut, and the edges of the remaining film remain on the guide surface of the cutting means 13, facilitating the next film withdrawal operation.

The main body 12 and the upper lid of the film cutting device of the present invention are made of organic plastic materials, such as thermoplastic resins such as acrylic resins, styrene resins, vinyl chloride resins, olefin resins, and polyester resins, or phenolic resins.
It can be integrally molded from thermosetting resins such as melamine resin and Yuria resin.

The film cutting device of the present invention can have a transparent or semi-transparent finish, which may be colorless or slightly colored (for example, blue, orange, or gnome), or it can have a colored opaque finish.

As shown in FIGS. 5 and 6, the upper lid part 11 and the main body 12
It is attached with a hinge 19 or other suitable means so that it can be opened and closed, and it is fitted with a fitting 20 when in use, as shown in Fig. 6.
It can be capped by any other suitable means.

Note that the front film drawer part between the upper lid part 11 and the main body 12 has a small width (for example, 1 to 3 mm) for the drawer film to pass through.
) is left in a relationship.

The film cutting device of the present invention has an elastic suction cup 21 made of an elastic material such as rubber or soft polyvinyl chloride located behind the center of gravity of the bottom plane of the main body 12 (on the back side of the center of gravity when viewed from the cutting means 13). and 22 (see FIGS. 7a and 8a) are provided with mounting holes or fitting holes 23 and 24 (see FIGS. 7 and 8) to provide a suitably smooth workbench for use;
It can be fixed to a table, wall, etc. and operated with both hands as shown in Figure 3.

The reason why the mounting holes 23 and 24 are provided behind the center of gravity is that when the main body 12 is fixed to a workbench and operated, if the mounting holes are in front of the center of gravity, the main body 12 will swing back and forth and become stable when the film is pulled out. This is because it cannot be operated.

The elastic suction cup is a fitting type suction cup 21 as shown in Fig. 7.
or a screw-type suction cup 22 as shown in FIG. 8, or any other known suction cup 22 may be used.

Further, as shown in FIG. 5, legs 25 can be attached to the bottom surface of the main body 12.

As explained above, if the present invention is followed, it will be possible to create a portable portable device that can be freely and extremely easily fixed to any workbench, table, wall surface, etc. using an elastic suction cup as needed in supermarkets, stores, and homes. A film cutting device is provided, and once fixed, the film can be pulled out with both hands as shown in FIG. 3 to obtain a cut film cut along perforations or cut lines, for example. If the items to be packaged are placed under the drawer film 16 shown in Fig. 3 and the items to be packaged are operated in sequence, the packaging operation can be carried out extremely efficiently and beautifully, and its practical value is extremely high. .

Since the device of the present invention is designed so that the suction cup is attached to the rear of the center of gravity of the device body, the device body can work extremely stably without shaking back and forth when drawing out the film.

In addition, in the device of the present invention, the roll film supports the ends of the cylindrical core body at both ends inside the main body, so the friction of the roll rotation when drawing out the film is minimized, and the drawing out of the film is extremely smooth. Cutting means 13
Therefore, the film can be cut very well, and the problems of conventional film cutting do not occur at all.

Furthermore, since the device of the present invention can be molded from plastic materials with various external colors, it is lightweight and beautiful, and since it comes with a lid, there is no problem from a sanitary standpoint.
