DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an adhesive tape, an adhesive tape and the like used for packaging and packing.
The present invention relates to a tape cutter which has adhesive surfaces adhered to each other and can be folded so that the end of the tape can be easily gripped when opened.

According to a second aspect of the present invention, when the tape is pulled out with one hand, the tape cutter main body is fixed by sticking the tape so that the light weight tape cutter main body does not move or fall down. So that it can be easily fixed to the table
The present invention relates to a tape cutter provided with an overhang.

[0003]

2. Description of the Related Art Conventional tape cutters with a cutting function are available on the market, but Japanese Utility Model Laid-Open No. 6-5887 has a folding function, but Japanese Patent Application No. 09-127781 bites a piece of paper. In addition, there are introduced tapes that can be easily peeled off.

[0004] In claim 2. Since the adhesive tape cutter is often operated with one hand, when pulling out the tape, the tape cutter moves or falls over the main unit, so fill the main unit with mortar to increase the weight, sucker or magnet on the bottom There was something provided.

[0005]

SUMMARY OF THE INVENTION If you use a tape cutter with only a cutting function that is on the market and affixed a tape with adhesive or adhesive, it is completely adhered, so it is difficult to peel it when turning it. In many cases, it will not turn unless it is scratched. In the case of wrapping paper, it can be opened by breaking the entire wrapping paper,
Some people want to keep the wrapping paper clean. If the paper or plastic is wrapped or durable, the tape must be turned. For example, when the main body and the lid of the can are wrapped with cellophane tape, the end of the tape is searched, and then the nail is started to be peeled off.
Since this action is difficult even for a healthy person, it is even more difficult for an elderly person or a physically handicapped person having weak physical functions.
For example, if the tape is transparent, it is difficult to find the end of the tape, and it is also difficult to remove the tape. Transparent tape is difficult to find at the end of a healthy person, even a blind person. It is difficult for a healthy person to peel off the tape that has been completely adhered, and it is necessary to stand up the nail and peel it off while scratching it.
In such a case, if the end of the tape is folded back, the portion rises, so that even a blind person or a person with reduced visual acuity can find it by touch, and can easily peel it off by pinching and pulling out the portion. Even if there are a lot of customers in the store, if you can get easy-to-open packaging and wrapping, how happy people with reduced physical function will be. However, the technology for making this folded knob is fully described in the gazette. I suppose the reason why they are not going to the market despite the fact is that customers are still waiting for something simpler. To this end, it is necessary to come up with a product that can be picked with as little operation as possible, and to provide it with a mechanically simple product that can be easily manufactured and sold at low cost in order to spread it widely.

[0006] Most of the existing prior arts are provided with a supporting portion between a cutter blade edge and a tape feeding portion, and by moving either of them, the distance is shortened, the tape is slackened, and the tape is picked. It is. Although many of these technologies have been published, they are not available on the market. Therefore, the present invention has conceived a device which does not have a movable part and exerts the same effect.

[0007] In the second aspect. When pulling out the tape in the packaging operation, hold the main body with one hand and pull out the tape with the remaining hand. However, since one hand often holds a package, if only the tape is picked out and pulled out, the whole body moves or falls. For this reason, in order to increase the weight of the main body, the mortar is filled or the bottom is made to be hard to slip. However, the pulling force of the tape is often higher. For that reason, once you release your hand holding the package,
After holding the main body with the hand, pulling out the tape and cutting it, the troublesome task of re-holding the loose packaging and attaching the tape occurs. In this case, the filler is
If a mortar having a specific gravity of about 2 or 3 is used instead of iron having a specific gravity of about 7 or 8, or a lead having a specific gravity of about 11 or 3, a heavy body that is hard to move without changing the bulk size can be obtained. However, this is not realistic because the material cost and the production cost are expensive. If this heavy product falls on your desk or workbench, you may be injured or your property damaged. And heavy objects have many problems in transportation, delivery, and movement.

[0008] As described above, the present invention aims at disseminating the tape with a convenient folded knob to the elderly, the physically handicapped, and the general and other users including those with a weak physical function. The purpose of the present invention is to provide an inexpensive tool that can be easily turned back and picked.

Such a technique has a folding function in Japanese Utility Model Laid-Open No. 6-58787, but is disclosed in Japanese Patent Application No. 09-127781.
In this article, a tape that is easily peeled off is introduced. In Japanese Utility Model Laid-Open No. 6-8787, two holding portions for the adhesive tape are provided at an interval, and if the interval is reduced, the tape rises, and if the portion is pinched, the tape can be folded. However, in this method, in order to make a turn, the operation of pressing the movable holding portion to shorten the interval,
Re-holding the picked tape increases the two actions.
Next, in Japanese Patent Application No. 09-127781, there is also a device in which a paper piece is adhered to the back side of the tape to form a knob portion. However, this method requires a separate piece of paper, and neither is mechanically simple. So we created something simpler and more convenient after much trial and error.

[0010]

[Means for solving the problem] I aim to be as simple as possible if the same effect can be obtained. This is because if it is simple, the operation is simple, the number of failures is small, the size can be reduced, the cost is low, and the amount of garbage is small even when it becomes waste. According to the first aspect of the present invention, the following is made. The tape-shaped thing wound up and wound up in a loop includes toilet paper and an adhesive tape. If you try to pick these tapes from the surface with your thumb and forefinger, you can pick the toilet pepper but not the adhesive tape. I thought about the reason for this difference. The most important factor is whether the back surface is bonded or not, but we also considered the case where both were not bonded. To pinch means to pinch an object between frictional surfaces. As a junior high school student, I felt that friction was determined by the coefficient of friction and the magnitude of the load.
Considering this theory, first, the coefficient of friction is in a relative relationship between a finger and an object to be gripped. The toilet paper has a rough surface and the adhesive tape is dense. The coefficient of friction of the finger is small in the dry state and large for the toilet paper in the sweating state, but small for the adhesive tape. This is because the moisture of the finger acts as a lubricating oil for slippery adhesive tapes and the slippery water is applied to the toilet paper due to the adhesion of water to the toilet paper. It seems that the power has increased and it is easy to pick. Next, it is not clear which is larger in the contact area, which is an element of the coefficient of friction, but when viewed microscopically, when a finger contacts toilet paper with an uneven surface, the finger contacts only the uneven convex part It seems that the adhesive tape with less unevenness has a larger contact area than the toilet paper that does. However, when strongly pressed, the flexible toilet paper conforms to the shape of the finger and dents, while the adhesive tape does not. At this time, the unevenness of the fingerprint on the finger surface and the unevenness of the toilet paper surface mesh,
It may be intertwined. Next is the angle to grab.
The tape laid flat has an outer angle of 180 degrees. When this is picked up and folded in two, the outer angle is from 180 degrees to 36
0 degrees. As you approach from 180 degrees to 360 degrees, you will understand that the shape becomes easier to pick. Based on this idea, a triangular (wedge) plate having a height of 2 cm and a width equal to or greater than the width of the tape was set up at a position about 1.5 cm away from the blade edge of the tape cutter toward the winding shaft. The tape was picked while holding the tape with the thumb and forefinger from the top of the board over the top of the board. However, it was able to be gripped, but this time the adhesive on the back of the tape stuck to the side of the plate with a triangular cross section and could not be pulled up. Therefore, I replaced the surface of the triangular plate with one that is easy to peel. For example, it was made of Teflon-coated one or one with release paper attached, but the tape adhered. Therefore, I made a triangular cross-section plate with a hard sponge with water absorption, and dipped the lower part in a water tank. Then, the sponge sucks up the water in the aquarium, the sponge surface becomes wet, the tape is easily peeled, and it can be picked up, but there is still a little adhesive strength, so the tape is repeatedly picked up many times When the action was repeated, the sponge surface was gradually adhered to the tape and peeled off, and after about 20 repetitions, the sponge surface became tattered and unusable. The next method I thought was to blow air from below. A rubber pad with a thin plate-shaped outlet is provided, and if you press the rubber pad with your wrist, the air will blow up from below, and the tape will be picked up by pressing the tape on the left and right sides of the blowing tape with your thumb and forefinger. is there. However, this did not work and the mechanism was difficult. I was discouraged here and gave up. Some years later, an idea came to my mind. The idea was that the tape would bend in a zigzag manner without supporting the entire width of the tape. When I immediately experimented, it worked better than expected. In the experiment, we cut out the straight part of a clip (stationery that sandwiched several documents and closed it), set it up like a pillar, used it as a tape receiver, and used it with a cutter blade of 1.5 cm.
The tape was pulled up to the place where the tape winding shaft had been reached, and the tape pulled out was put on it, straddled the clip column, pulled out beyond the cutter blade, and pushed down to cut the tape. Next, hold down both sides of the tape straddling the clip pillar with your thumb and forefinger downward, and narrow the width between the fingers as it is.The tape will bend from a curvilinear shape to a U-shape, and the left and right tapes The backs were stuck together, and when pulled up, the folded tape was lifted. The point to note here is to grab the tape, avoiding the clip post. That is, if the tape width is 1,
If it is about 5 cm, it means that it is pressed against the clip column at the side end of the tape width. If the tape width is wide,
For example, if it is about 5 cm, even if the clip column is set up in the middle of the width, it can be picked up sufficiently with the tape-side end.
Before this experiment, I was worried that the tape would not break, and that the shape of the tape that was pressed would be Mt.Fuji, that is, a conical shape. It has just come off. In spite of being worried about tearing, despite the fact that it was supported by a clip column with a diameter of only about 1 mm, the cellotape did not tear, and it did not become a conical shape even if it was pressed down, it was quite surprising that it became a gable-shaped roof Met. It ’s easier to lay than you ’d expect,
In short, thinking was interrupted for a long time by the wrong stereotype. I think that it is an illusion that many people have without thinking that the tape will not bend in a zigzag without supporting the entire width of the tape. The present invention has been completed by finding this phenomenon. And since a clip pillar is not limited to a clip, in this invention, it is called a push-up part.

In the second aspect, the base 6 at the bottom of the main body 9 is springed out from the surface of the main body to form an overhang portion 7,
This and the surface of a desk etc. were stuck with adhesive tape etc., and the main body was fixed. Then, without holding down the main body, I was able to pull out the tape with one hand and cut it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a perspective view showing the whole of the present invention. 9 is a main body of a commercially available adhesive tape cutter. In this drawing, only the push-up portion 3 and the overhang portion 7 are newly added parts of the present invention.
The position of the push-up portion is between the tape peeling start portion 1 and the cutter blade edge 2. The vertex position of the push-up portion 3 must be above the plane connecting the peeling start portion 1 and the cutter blade 2. Otherwise, the tape will not bend in a U-shape. At first, pull out the tape wound on the take-up shaft, pass over the top of the push-up part 3,
When the tape passes over the cutter blade 2, it is lowered, and when the tape is brought down against the blade, the tape is cut and the state shown in FIG. 1 is obtained. From the next, hold the tape with your thumb and forefinger on the left and right sides of the tape that straddles the push-up section 3 and squeeze the tape. See FIGS. 2 and 3; at this time, pick only the front side of the tape width and pick the entire tape width. No. This is because if the entire body is pinched and pinched, the push-up portion 3 is also grasped, so that the tape cannot be pulled up. In order to make this action possible, the width dimension 5 smaller than the tape width 4
Thus, the tape is pushed up and supported.

As for the method of providing the push-up portion, a variety of types can be produced by employing existing technologies such as a retractable type, a plug-in type, a removable type, a folding type, and the like. With a structure in which the height of the push-up portion or the distance from the cutting edge position can be changed, the folded length of the tape can also be changed. For example, the thrusting part is not perpendicular to the tape, but the angle is inclined about 30 degrees, or the embedding part of the thrusting part into the main body is a screw type,
For example, it is possible to change the push-up dimension.

Further, the position where the push-up portion is provided is inserted into the push-up portion mounting hole denoted by reference numeral 12 shown in the plan view of FIG.
When fixing is possible, it can be changed to an easy-to-use one for left-handed people by replacing the push-up portion.

According to the second aspect, as shown in FIG. 1, a projecting portion 7 from which a part of the base 6 is projected projects from the surface of the main body 9. Reference numeral 8 denotes an adhesive or sticky tape. The tape is stuck on the surface of a top plate such as a desk or a work table, straddling the overhanging portion 7. Then, the main body can be fixed to the base by the adhesive function of the tape.

However, if it is said that this shape is bulky for packing or stock as a product, a hole 10 is opened in the main body as shown in FIG. 5, a bar 11 is inserted into the hole, and the bar is attached by tape and fixed. Can be fixed as well. When the rod 11 is not required, as shown in the drawing, the holding means 13 to the main body is used.
May be provided and stored here. The rod can be stored by utilizing such existing storage technology. The tape can be used only when necessary, and it can be used as it is, just like a conventional tape cutter. In this embodiment, the bar 11 is the overhang 7.

[0017]

According to the first aspect of the present invention. 1. The simplicity of the structure means that there are few failure factors, and it is inexpensive and easy to spread. 2. One-touch tape with folded knobs at the end. 3. Since the tape can be cut in the same position as the picked tape and brought to the sticking position, there is not much difference from the conventional cutting only operation. No, since it doesn't grip the adhesive surface any more, the pasting is smooth. And after the tape is cut,
Next, it is waiting for the tape cutter in the form of being picked up, so it is very convenient when sticking the tape in a continuous operation. 4. When pulling out the tape from the take-up shaft and hanging it on the cutter blade, it can be used as a conventional tape cutter for cutting only by pulling it slightly forward and pulling it out so as not to hit the push-up part 3. It does not take up a small space by placing two units, and there is no need to switch function operations. 5. It can be used for a portable tape cutter as shown in FIG. 6. In the process of cutting the tape, the instrument has no moving parts, so it is simple to use and easy to use.

[0018] In the second aspect. 1. Since the product can be fixed without increasing the product weight, even with a tape with strong adhesive force such as an adhesive tape, the tape can be pulled out and cut with one hand without holding down the main body. 2. The ability to reduce the product weight is convenient for transportation, transportation, loading, and storage.

As described above, according to the present invention, it is possible to promote the spread of a tape with a knob which can be easily opened at the time of opening without adding any extra operation. Wrapping with this easy-to-peel tape does not reduce the adhesive strength at the time of packaging, but it is easy to open, so it is particularly convenient for those with reduced physical functions.
