DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long plastic wrap film wound around a cylindrical core in a coil shape, aluminum foil, kitchen paper, and the like. And a container provided with a cutting cutter for dispensing these long films for use. More particularly, the present invention relates to a container provided with a cutting cutter made of a novel material.

[0002]

2. Description of the Prior Art Conventionally known cutting cutters for such containers are usually made of thin mild steel sheet. Therefore, when treating this container as waste with the cutter attached,
There is a problem that this cutter is not suitable for incineration, and is dangerous even when buried in a waste disposal site because the cutter does not rot or decompose.

[0003] For this reason, this type of container has to be removed with a metal cutter before being discarded, but this removal is not easy, and the end user who disposes of the container has low interest, so that the container is completely removed. At present, it has not been executed. In addition, such containers are often inadvertently thrown into the environment, in which case there is a risk that the sharp blades may damage livestock, wild animals and plants.

[0004] In addition, manufacturing this metal cutter and attaching it to a container requires considerable cost, and inevitably wastes valuable metal resources for a cutter that is used for an extremely short period of time. In addition, conventionally known metal cutters are manufactured by shearing a thin steel plate, so that the cutting edge is not sharp, and is susceptible to plastic deformation due to poor stiffness and elasticity. There is a problem in that cutting requires considerable force and knack.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above description.
It is an object of the present invention to provide a new container with a cutter which solves the above-mentioned problems, is easy to use, and has low waste pollution.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is as follows.
This is achieved by using a plastic cutter which decomposes in the natural environment, or a cutter made of paper impregnated with such a plastic. As the plastic to be used, polyglycolic acid, polylactic acid, polycaprolactone, poly (3-hydroxybutyric acid), poly (3-hydroxyvaleric acid) or poly (4
-Hydroxyvaleric acid), or a mixture or copolymer thereof.

[0007] These substances are sugar cane and other agricultural products,
In particular, it is obtained from parts that were conventionally regarded as agricultural waste, and does not require fossil raw materials. Also, the cutter is
It may be manufactured by cutting the sheet, but at this time, it can be processed into a cross-sectional shape that can give sufficient stiffness and elasticity by applying mild plastic working so as not to undergo plastic deformation during use. Are also sharply constructed.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a cutting cutter is made of a plastic or a paper impregnated with such a plastic which decomposes in a natural environment. Plastics used include polyglycolic acid, polylactic acid, polycaprolactone, and poly (3
It is recommended to employ -hydroxybutyric acid), poly (3-hydroxyvaleric acid) or poly (4-hydroxyvaleric acid) or mixtures or copolymers thereof. or,
These plastics have appropriate fillers, extenders,
A coloring agent, a stabilizer, a decomposition accelerator, and the like may be added.

Further, when these plastics are used alone without impregnating the paper, it is recommended to use a hard material having a Rockwell hardness R90 or more. A sheet having a thickness of about 0.15 to 0.8 millimeters is formed with these plastics, or a sheet-like material of the same thickness impregnated with the above plastic is used, and has a desired cross-sectional shape and saw blade. It is molded into a cutter for use.

As the paper-like material, paper, plant-based woven fabric, non-woven fabric, net, and the like are used. When the paper is impregnated with plastic, the cutter may be formed integrally with the box using a part of the material forming the box. As a method of attaching the cutter to the box, it is recommended to use a highly degradable adhesive of the same system, a plastic fastener of the same type as the cutter, or the like.

These plastics do not require petroleum-based materials as raw materials, are produced using agricultural products and plant stems and leaves which have not been used as conventional agricultural wastes, and are produced under microorganisms in a natural environment. It is decomposed into harmless carbon dioxide gas and water by the above method. Therefore, unlike the case of other petroleum-based synthetic resins, they do not seriously harm the health of those animals even if they may be mixed into the feed of wild animals or the like during the decomposition process. Further, it can be easily treated as garbage, can be incinerated together with a box, and can be composted with garbage and the like.

The configuration of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a configuration of a container with a cutter according to the present invention, and FIGS. 2 to 8 are explanatory views showing a cross-sectional shape of a recommended cutter. However, FIG.
In order to clearly show the shape of the cutter, the paper constituting the box and the thickness of the cutter are particularly exaggerated.

In the drawings, 1 is a container with a cutter, 2 is a long film, and 3 is a core. The cutter-equipped container 1 comprises an elongated paper box 10 provided with a paper-made cutter 11 or 12 made of plastic or a plastic impregnated in a natural environment.

The shape of the cutter may be the same as that of a conventionally known metal plate saw blade. However, it is recommended that the cross section of the saw blade portion has an acute angle as shown in FIG. Is done. Furthermore, especially in the case of being provided along the outlet of the film 2, in order to increase the bending strength of the cutter, FIG.
As shown below, it is recommended that the cross section is not a simple one-character cross-sectional shape, but a U-shape, an L-shape, a G-shape, or a rib provided along the cutting edge line.

The cutter 12 is provided along the outlet of the film 2 of the container, and the cutter 11 is provided along a ridgeline near the outlet. This cutter
It is sufficient if one of 11 and 12 is provided, and the mounting position of the cutter is appropriately selected according to the material of the film 2 and the like. Thus, the film 2 is pulled out as necessary, cut by the cutter 11 or 12, and provided for use.

The cutter 13 shown in FIG. 3 has a U-shaped cross section and protrudes a rib along a cutting edge line.
Further, in order to sharpen the saw tooth portion, the cutting edge is formed to have an acute angle. FIG. 4 shows a cutter 14 in which a rib is projected along a cutting edge line from a one-letter shaped cutter cross section to form a generally C-shaped cross section.
Also in this embodiment, the cutting edge is formed at an acute angle.

The cutter 15 shown in FIG. 5 has a cross section bent in a U-shape in a direction opposite to that of the embodiment shown in FIG. FIG. 6 shows a cutter 16 in which ribs are provided so as to have a J-shaped cross section as a whole, and the blade length is further reduced. The cutter 17 shown in FIG. 7 is a modified example of the cutter shown in FIG. 4, and has a high rib and a low blade height.

FIG. 8 shows an example in which a cutter 11 is provided on the bottom surface of the container 1. It is clear that a cutter having a cross section as shown in FIGS. 3, 4, 5 and 7 can be used even when it is attached to the bottom of the container for this purpose. Thus, the cutter having the cross-sectional shape as shown here can be easily formed from a sheet by plastic working.

[0019]

According to the present invention, the cutter of a container with a cutter decomposes in a natural environment, and can be discarded with the cutter attached to the container. Even if left unattended in the environment without care, it is relatively quickly decomposed and disappears, so it does not damage humans and wild animals, and saves valuable metal and oil resources. And so on.
