Abstract

<P>PROBLEM TO BE SOLVED: To provide a carton cutter for recycling used drink cartons. <P>SOLUTION: This carton cutter, with its body being held in one hand, is designed to cut a cornered edge of a box carton with a pull along the edge in a slight contact in a sliding manner after inserting the cutter's blade tip in the opening of the carton. The blade, which is gently curved like a fishhook, includes an inner edge to cut along the edge of the carton, and a spherical body fixed at the tip of the blade. The spherical body helps keep the blade from coming out of the carton or hold it inside when the body is being pulled, or even if too much pulling power is applied to force the blade happens to come out, the spherical body prevents it from injuring a user. The cutter body near the blade is scraped off to be rounded, so that it can easily be turned in a different direction to keep cutting without being taken out after finishing cutting the first side. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention makes it possible to easily cut a rectangular box, such as a paper pack for beverages, for specified recycling for recycling.

For disposal and collection of paper packs and cardboard as resources, cutting and cutting at corners is better for collection and storage. Many housewives are now using paper scissors, cutter knives, etc., after washing and drying paper packs that have been drunk in the kitchen. In addition, when the corner of an object such as a box is deformed, the cutting direction changes greatly.

Paper box cutting tool

Problems to be solved by the invention

When cutting with conventional scissors, the burden on the hand is large and troublesome, and with a normal cutter knife, the direction changes greatly depending on the angle and force of the arm when cutting, which is dangerous.
When the corner of the object to be cut is crushed and deformed, the cutting direction changes greatly.
Means for easily cutting paper packs and the like are not widespread.

Means for solving the problem

It is a tool that cuts the tip of the blade fixed to this device while sliding it in the way of inserting it through the opening of the target paper pack and pulling it forward. The sphere is fixed to the tip of the blade that is bent in this way, and it corrects the force acting to bend from the inside when the device is slid and cut by hitting the side and face inside the target box. .
The shape of the lower part of the main body of this device is an isosceles triangle with an inner angle of 90 degrees at the center of the main body. The main body to which the cutter is fixed is transparent, so the blade can be checked at any time by inserting the tip of the cutter once through the opening of the target box and cutting the side. One side of the trapezoidal portion at the bottom of the device is cut 45 degrees from the 90-degree vertex of the isosceles triangle space so that the direction can be easily changed while inside the box vertex.

The invention's effect

Can be cut quickly and easily, such as beverage paper packs and tissue boxes.
If the main body is transparent and the shape of the lower part of the main body is the same, coloring it into an egg shape will also make it an interior accessory for the kitchen, and the spread of this tool can increase recycling at ordinary homes. You can say that.

In order to correct the deformation and distortion of the box when this device is pressed against the target box from the outside, it is necessary to have a surface to be held down at each 45 degree opening centered on the protruding blade. . In addition, the body is ideally large enough to be held with one hand so that the elderly can use it. The tip of the blade protrudes within 2 cm from the front side of the lower trapezoid. If the material of the main body of the apparatus excluding the blade is transparent, the position of the blade being cut can be confirmed.

The blade is inserted into the opening of the paper pack as if it was hooked and slipped as if it were pulled forward.

Large packaging boxes can be cut by processing a large centimeter.

This device combines two deformed trapezoids that are symmetrical, and becomes one, but the shape on one side is either one of the corners of the isosceles triangular pyramid with each d-plane as the base. In this case, the shape where f is the apex, the side extending from f to apex k, and the side extending from f to apex j at an angle of 45 degrees to side e is cut vertically. It is figure (1). In addition, the respective angles are b45 degrees and c90 degrees. Next, FIG. 2 shows a state where the triangular pyramid side e is the floor surface and the a-faces are assembled by facing each other. The blade is fixed in a state of being sandwiched between the blades assembled in a form in which the a-faces are opposed to each other. At this time, in order to prevent a gap corresponding to the thickness of the blade from being opened, the blade is fixed in a shape that the blade is sinking while the half of the thickness and the screw head are engraved in the shape of the blade on each a surface.

It is a three-dimensional view showing (1) It is a three-dimensional view showing (2) It is the top view which showed (3) It is sectional drawing which showed (3) It is a three-dimensional view showing the use state of the present invention

Claims (8)

A sphere is attached and fixed to the tip of the blade fixed to the apparatus. There are two holes in the blade fixed to this device, and it is screwed. The body to which the blade is fixed is transparent, and the position of the blade can be confirmed even during cutting. The main body is divided into two, and the blade is fixed in a shape sandwiched between the main bodies When sandwiching the cutter with the main body, the main body side is carved into the shape of the cutter by the thickness of the cutter so as not to open a gap corresponding to the thickness of the cutter. Only the trapezoidal portion at the bottom of the main body is cut at 45 degrees from the upper apex of the surface opposite to the traveling direction. This is to change the cutting direction at the apex of the object without cutting the object while cutting the object with the blade. The position where the tip of the blade protrudes from the main body is within 2 cm from the surface opposite to the direction of travel. The purpose of this device is to cut the corner of the box while pulling it inward from the corner of the opening of the target box.
