Description

[Detailed Description of the Invention] The present invention relates to a tape cutter, and more specifically, when using adhesive tape such as cellophane or film, the tip of the starting point can be easily picked out. The present invention relates to a tape cutter in which the cutting teeth can be brought close to each other and the shape of the tape cutter body can be made into any desired shape.

Conventional tape cutters have either a serrated cutter that is slidably engaged with the tape roll in the circumferential direction, or a tabletop tape cutter that has a ring tube part that applies the core of the tape roll. , there were cutters equipped with serrated cutting blades for cutting the tape, but these cutters caused the beginning of the tape to stick to the tape roll or the cutting blade.
There were disadvantages in that it was difficult to ideally pull out the tape to pick out the tip when starting to use it, and cutting the tape was not smooth.

Therefore, a tabletop tape cutter and the like has been proposed in which the tape rotation part and the cutting teeth are separated from each other to provide a space for the fingertips so that the user can pick the tape near the end rather than at the beginning of use.

However, with this, it is necessary to provide a space for the fingertips to fit into the tape cutter body, so the shape is fixed and it is not possible to use tape cutters of various shapes.Furthermore, the shape is special, and the tape cutter itself becomes large. It had the disadvantage of being stored away.

The present invention eliminates these drawbacks and provides a tape cutter that allows the tape to be easily picked out at the beginning of its use, and which also allows the shape of the tape cutter body to be made into any desired shape. The purpose is to

In other words, the present invention allows the tape to be removed freely.
In a tape cutter comprising a tape cutter main body having a ring tube part that can be held freely in rotation, and a cutting tooth part having a serrated cutting blade at the tip, the cutting tooth part is bent into a substantially trapezoidal shape, and a ring is attached to the upper side of the tape cutter body. The present invention provides a tape cutter characterized in that a shaped elastic body is fixed and a serrated cutting blade is formed at the tip of the oblique side.

Hereinafter, embodiments of the tape cutter according to the present invention will be described with reference to the drawings. FIG. 1a is a perspective view showing an embodiment of the tape cutter according to the present invention.
Figure b is a sectional view taken along line A--A in figure a. In the figure, reference numeral 1 denotes a tape cutter main body that can be divided into front and rear parts, and a ring tube part 4 for receiving a core 3 of a winding tape 2 is protruded from the inner wall surface of the cutter main body. Cutting teeth 5 are provided at the end of the tape cutter body 1. A serrated cutting blade 6 is formed at the tip of the cutting tooth 5, and a ring-shaped elastic body 7 is fixed to the upper surface of the cutting tooth near the serrated cutting blade. It is necessary that the upper part of the ring-shaped elastic body 7 be located above the position where the serrated cutting blade 6 is formed. In the present invention, the cutting tooth portion 5 is bent into a substantially trapezoidal shape, a ring-shaped elastic body 7 is fixed to the upper side thereof, and a serrated cutting blade 6 is formed at the tip of the oblique side. The material of the ring-shaped elastic body is not particularly limited as long as it has a cushioning effect, but synthetic resin is preferred. FIG. 2a is a perspective view of a tape cutter according to the present invention in which the shape of the tape cutter body is different;
FIG. 2b is a sectional view taken along the line B--B in FIG. 2a. Note that the shape of the tape cutter main body 1 is not limited to that shown in FIGS. 1a and 2a, and may be in various illustrative design shapes such as small animals, insects, and small birds. In addition, the whole or at least the side surface of the tape cutter body 1 is made transparent or visible, and a circular adhesive sheet or film corresponding to the cross section of the wound layer of the tape is placed with small animals, insects, small birds, etc. If you print illustrations, scales, letters, figures, symbols, brand names, color identification, etc. and fix them with adhesive, the printed display surface will rotate with the tape inside the tape cutter when the tape is pulled out. The drawn-out length of the wound tape can be easily measured visually based on the rotational movement position of the pattern on the printed display surface, etc., and the inconvenience of the drawn-out tape being too long or too short can be solved. Furthermore, since the displayed contents are illustrations, symbols, etc., it is easy to visually assess the tape, and even infants and children in lower grades can enjoy using the tape. Furthermore, the cross section of the tape winding layer is free from dirt and dust, allowing the tape to be used cleanly.

When using the tape cutter according to the present invention having the above-mentioned configuration, after applying the core 3 of the wound tape 2 to the ring tube part 4 of one of the divided tape cutter main bodies 1, the other tape cutter main body 1 is fitted. , the winding tape 2 is rotatably locked to the tape cutter body 1.

In this state, the tip of the wound tape 2 is pulled out and the tape is pulled downward at the required length position, and while the ring-shaped elastic body 7 is bent by the tape, the tape is brought into contact with the serrated cutting blade 6 and cut. The cutting pattern of such a tape is shown in FIGS. 3a and 3b.
Figure 3a shows a state in which the tape 2 is being pulled out and cut, and the ring-shaped elastic body is deformed into a flat shape, and the force that tries to return it to its original state is applied as shown by the arrow. is working. On the other hand, the tape cutting force is applied in the opposite direction, so the tape can be cut easily and easily. After cutting the tape, the end of the tape is lifted away from the serrated cutting blade 6 due to the repulsive force of the ring-shaped elastic body 7, as shown in FIG. can be easily extracted.

Therefore, according to the present invention, the tip of the tape at the beginning of use can be kept in a state where it is always lifted up, away from the serrated cutting blade, so the tip of the tape at the beginning of use can be easily picked out, and the tape can be easily cut. It can be done smoothly. Furthermore, since the tip of the tape is always raised, there is no need to provide a space between the tape rotation part and the cutting tooth part to insert your fingertips, and the tape rotation part and the cutting tooth part are placed close together. This makes it possible to create a monolithic design. Therefore, the main body of the tape cutter can be designed in various illustrative designs such as small animals, insects, and birds, making it possible for infants and children in lower grades to enjoy using tape, and making the tape cutter itself compact. It has the excellent effect of being able to create a tape cutter with a new image.
