At that time, it is necessary to move the inserted section slightly forward and backward in order to fix the shorter gnono 5 3, 5 3 '. Formed in an inverted U-shape on the bottom near 3 'and inserted pin-shaped objects into small holes r and r' (Fig. 1) exposed from the inclined grooves 4 2 and 4 2 '. You may make the section move back and forth. The intersections of the phase notches 5 1 and 5 1 ′ should be provided so as not to cause unevenness and gaps as much as possible.

The V-shaped part V (Fig. 1) located at the top of the two sections crossed in an X shape When the folding lid 40 is completely closed after cutting, the ridge angles of the cutting tools AB 5 0 a and 5 0 b that are back to back lose their mutual contact and stick together. Preventing,

The cutting form with X-shaped cutting tool A 5 0 a and horizontal straight cutting tool B 5 0 b is to cut the film from both ends to the center by two-point contact, and to cut with a saw blade. Instead, the cutting tools AB, 50 a, 50 b, which have high hardness, are pointed in contact with each other in a continuous point, and are squeezed by sliding while applying moderate pressure. It can handle wrapping films with various characteristics of softness and softness without the need to draw the drawn film. It is also possible to release the film from the drawn film and cut it. The cut will be a straight line.

The two ribbon-shaped pieces forming the cutting tool A 50 a are tilted in two directions of the length direction and the width direction in a bilateral manner, and the cutting tool B 50 b is inclined only in the width direction. In order to make the ridge angles of the two points as close as possible to each other, the cutting tools AB, 50 0 a, 50 0 b in a state of being held together are provided so that their inclination directions in the width direction are mutually reversed. The reason for this is to ensure smooth blending of the two.

The cutting tool A 50 a can be attached using a screw or an adhesive without depending on the above-mentioned fitting type. It is desirable that the sections forming the cutting tools A B, 50 a and 50 b are subjected to quenching after being processed and molded as described above.

In the present invention, the rear lid 40 0 b and the cutting tool B 5 0 b are simultaneously attached to the main body 1 via the brackets 20 and 2 0 ′, and the cutting tool A 5 0 a is assembled. 4 0 a is attached to the rear lid 4 O b, and the side caps 3 0, 3 0 'with the rotating pressure plates 3 6, 3 6' and the fasteners 3 5, 3 5 'are attached to the brackets 2 0, 2 0 'Connected to the bottom wall cancerous spaces 2 5 and 2 5' with 2 retaining pins 2 8, 2 8 ', 4 7 and 4 1' (Fig. 1, Fig. 2). Bracket 2 0, 2 0 'All but 2 fixing screws 2 7 and 2 1' are fitted or connected by pins, so assembly is easy. Easy.

When starting to use the present invention, open the front side cap 30 or 30 '(Fig. 2) and rotate the new wrap film roll 1 2 in the direction opposite to the direction of drawing the film. After loading the main body 1 into the main body 1, open the apron 4 1 with the thumb of the hand holding the main body 1 (Fig. 1) and pick up the label or tape attached to the roll 1 2 outlet. Pull out the film, close the half-foldable lid 40, and close the apron part 4 1 Make both ends of the apron abut the cutting tool B 5 0 b just before the ends of the apron part 4 Just slide 1 in. The apron portion 41 is then changed to the cutting tool A 5 0a on the back side of the apron portion 4 1 and the front surface of the main body 1 while changing the direction of rotation and the turning radius via the folding part hinges 4 6 and 4 6 '. The ridge angles of the upper cutting tool B 50 b are continuously brought into point contact with each other. After that, pulling out the folding lid 40, pulling out the film, abutting both ends of the apron 4 1 at the bottom of the cutting tool B 5 0 b, and sliding while applying an appropriate force repeat. When the contents are used up, simply open the side cap 30 or 30 'and remove the empty core 13 and refill it with a new roll 12.

The roll 12 is loaded so as to rotate in the direction opposite to the film pulling direction. When the film is pulled out suddenly, the area where the drawn film is separated from the roll 12 is near the roll. This is to prevent the film from being drawn into the front edge of the film take-out port 2 due to over-rotation of 1 2.

The cutting tool AB, 50a, 50b in the state of being squeezed with each other can be set to have a forward direction of inclination in the width direction, or the cutting tool A50a can be inclined straight or V-shaped. It is also possible to provide a Λ shape with a short ridge protruding at the apex.

The present invention is provided with a detachable pedestal so that it can be used as a stationary base. Alternatively, the same cutting method can be used for deferred use only. In that case, a panel or elastic body is attached to the folding lid 40, and an appropriate pressure is always applied to the apron 41, so that the lid 40 is attached. It is desirable to be able to cut the film just by closing it.

It is also possible to provide the refill container of the present invention for a foil-like body such as an aluminum foil. Industrial applicability

Since the present invention is configured as described above, the present invention has applicability as described below.

By rotating the cutting tool A tilted in two directions, the length direction and the width direction, through the center folding lid, and rotating it while changing the rotation radius, the cutting tool B tilted only in the width direction. Continuous point contact between ridge angles becomes possible.

In addition, it supports film-like bodies with various characteristics of hardness and softness by making more rational cutting methods by making point contact between ridge angles with sufficient hardness continuously and sandwiching the film drawn between them. And show excellent sharpness.

In addition, the cutting tool AB is not provided with any blades or saw blades, so there is no risk of injury to the fingers, and there is no need to pull the film or move the container to cut, reducing the burden on the wrist. The film cut by the reaction does not get tangled. This allows a deferred type.

When the lid is bent, the lid opens and closes, the load on the thumb is low, and the apron bottom is cut out in an arc shape, so that the lid can be opened. The opening space in the center of the main unit is expanded. At that time, the cutting edge of the film is rolled up by the cutting tool A and lifted up, so that the cutting edge can be easily picked up.

Since the roll is supported by the rotary pressure plate so as to be separated from the inner surface of the main body, the film can be pulled out smoothly, and there is no rolling back, popping out of the roll, or rattling. In addition, this makes it possible to provide the main body and the curved surface of the lid in a transparent or colored and translucent manner, so that the remaining amount can be seen at a glance and the appearance becomes attractive. The cutting sound is made gentle by the cutting method that rubs the ridge angles of the cutting tool AB.

The external dimensions are compact due to the trimmed component structure.

Because the mechanism is simple and all parts are made of durable materials, it has high durability, the number of parts is small, and all but two screws are fitted or connected with pins. It is suitable for mass production and is advantageous for assembly cost.

By eliminating the need for conventional paper boxes, it is economical and contributes to resource saving and waste reduction.
