Abstract

To minimize the number of components of a safety cutter while keeping a safety cutter's function of being attached to a refrigerator or the like and cutting a plastic bag or a pouch pack containing food.SOLUTION: In the present invention, a cutting blade is attached at a fixed angle to a base having a surface parallel to an attachment surface of a refrigerator or the like and having a plurality of magnets therein in such a manner that a cutting edge faces the base. A cover is provided with a fixed gap between itself and the base so as to prevent a hand finger from touching the tip of the cutting blade and the cutting edge exposed from the base. A plastic bag or a pouch pack containing foodstuffs or the like is cut between the base and the cover. As a result, a distance between the attachment surface of the refrigerator and the cutting part of the cutting blade can be reduced, and pulling-off force caused by a load upon cutting is reduced, so that the number of the magnets attached to the wall surface is also reduced. In addition, a support frame or the like for supporting the cutting blade becomes unnecessary. The number of components is further reduced by manufacturing through resin insert molding in which the magnets and the cutting blade are incorporated.SELECTED DRAWING: Figure 3

Description

The present invention relates to a safety cutter that is attached to a side surface of a refrigerator or the like to easily and safely cut a plastic bag or a couch pack containing food or the like.

In recent years, the number of products in which vegetables and cooked products are put in plastic bags or couch packs is increasing rapidly because they can be eaten quickly just by warming them and they can be eaten deliciously due to improvements in cooking and storage techniques. Many of the plastic bags and pouch packs have slits so that they can be torn by hand, but when the hands or these are wet and slippery and cannot be torn, the room is dark, or the eyes are poor and the slits are difficult to see. , I often squeezed with scissors.

As a countermeasure, a safety cutter that can be attached to a refrigerator or the like with a magnet and cut between a roller and a cutter blade has been proposed. As a result, even when your hands or plastic bag are wet, or when the room is dim and the slits are difficult to see, you can easily cut the plastic bag and couch pack, and you can also cut other paper packs such as milk and juice, and the cutter. It is very convenient because it can be used semi-permanently if the blade is replaced, but it has many parts, the structure is complicated, and the cost is high, so it has not been possible to expand sales.

The problem to be solved is how to attach it to a refrigerator or the like to leave the function of cutting a plastic bag or couch pack containing food, and to configure it with the minimum number of parts.

In the present invention, the cutting blade is attached at a constant angle so that the blade faces the base having a plurality of magnets having a surface parallel to the side surface of a refrigerator or the like, and the tip of the cutting blade and the blade protruding from the base are hand-held. Provide a cover with a certain gap from the base so that your fingers do not touch it, and cut the plastic bag or couch pack containing ingredients etc. with the cutting blade between the base and the cover, and do not replace the cutting blade The most important feature is to use up.

It was possible to configure it with the minimum number of parts, which is close to the limit, while retaining the function of a safety cutter that can be attached to a refrigerator to cut plastic bags and couch packs containing food.

This figure is a perspective view of an embodiment. This figure is a front view of an embodiment. This figure is a left side view of an embodiment. This figure is a bottom view of an embodiment. This figure is a perspective view showing a usage state of an embodiment.

It can be attached to a refrigerator, etc., leaving the function of a safety cutter that cuts plastic bags and couch packs containing food, and can be configured with the minimum number of parts that are small and close to the limit, and many people in various fields. Has become easier to purchase, and sales are expected to grow.

As shown in FIG. 3, the present invention has a surface parallel to the side surface of a refrigerator or the like to be attached and used, and a cutting blade 2 is angled with respect to the surface of the base 1 on a base 1 having a plurality of magnets 4 inside. A cover 3 is provided so that fingers and the like do not touch the tip of the mounting and cutting blade 2 and the cutting blade 2 protruding from the base 1, and a safety cutter slides on the mounting surface side of the base 1 due to the load at the time of cutting. A non-slip mat 5 is provided so as not to prevent it. When cutting a plastic bag or couch pack containing food, use the fingers of both hands to place the end of the plastic bag or couch pack 6 on the cutting portion 2a between the cutting blade 2 and the base as shown in FIGS. 5 and 3. If you pick it up, you can easily cut it. In addition, the cutting portion 2a where the base 1 and the cutting blade 2 intersect is set to an extremely small distance from the mounting surface of a refrigerator or the like, and the mounting surface of the base is also set wide, so that the load at the time of cutting can be increased. The safety cutter is less likely to slip, and fewer magnets can be used. Also, as seen in FIG. 4, the cutting blade is thin, and the cover and the cutting blade itself are likely to break due to the lateral load applied to the cover, but the cutting blade is attached at an angle of about 20 degrees, as can be seen in FIG. Since the exposed surface of the cutting blade to which a load is applied is wide, the strength is sufficient and a support frame for receiving the cutting blade is not required. Further, if this safety cutter is manufactured by insert molding such as resin in which a base and a cover having built-in parts such as a cutting blade and a magnet are integrated, further no coupling parts are required.

Since it is a small and extremely simple safety cutter, it can be attached to the side of various things other than attaching it to a refrigerator to cut plastic bags and couch packs containing food, and bags containing liquids such as vinyl strings, fishing lines, and detergents. There are various possible uses such as cutting.
