Description

In the present invention, thick paper with flossed circular holes is double-folded to form a bow shape and inserted into the oral cavity, and tension is applied to the floss corresponding to the bowstring to create interdental or tooth teeth. Regarding the interdental cleaning tool that cleans the interdental surface.

As in Patent Document 1, an arch-shaped, U-shaped, semi-circular, etc. bow trunk is formed from synthetic resin, and dental floss (hereinafter abbreviated as "floss") is stretched between both ends of the bow trunk, and at one end of the bow trunk. Interdental cleaning tools with integrally formed handles are generally known. However, since these interdental cleaning tools are made of synthetic resin, they are highly elastic when they are new, and the tension that has reached the limit is released at once, especially when passing between teeth with almost no gaps, and the gums are elastically released. It could hurt me. On the contrary, when the floss portion is pulled out after cleaning the inter-tooth teeth, the floss portion is also pulled out instantly, so that the finger or the hard main body portion may hit the opposing teeth and cause pain. Due to such fatal flaws, it was dangerous, especially for children in need of oral care, and was not widely used.
In addition, when the bow trunk is permanently deformed during use, or when there is almost no gap between adjacent teeth and the floss is in close contact with each other and it takes time for the floss to pass between the teeth, the bow trunk is permanently deformed. As a result, the tension of the floss is impaired and the teeth cannot be slid smoothly. Alternatively, there is a drawback that the floss is loosened or the fixation between the floss and the bow trunk is loosened, so that the sliding by the floss is impaired.
On the other hand, the product of the present invention is made of paper, has no elasticity, and the force can be easily adjusted, so that it does not damage the gums and can be used safely by first-time users and children.
In addition, many people have to carry an interdental cleaning tool at all times and always clean their teeth after eating, but conventional interdental cleaning tools are too large and bulky, so they are not suitable for carrying. ..

Therefore, as in Patent Document 2, the inventor of the present invention is not bulky and is suitable for carrying by manufacturing with thick paper instead of synthetic resin, and can be manufactured at low cost. In particular, the bow trunk is pulled by floss and deformed. We proposed a paper product that allows floss to effectively slide and clean the tooth surface with sufficient tension when it is constantly pressed against the tooth.
However, in the structure of Patent Document 2, it is difficult to control the tension of the floss, and the tension is loosened during use, so that the tooth surface cannot be brushed smoothly.
The technical subject of the present invention pays attention to such a problem, and when the cardboard main body is folded in half and stacked to form a bow shape, the floss is tightly tightened and can be used reliably without loosening. We propose possible structures, their usage methods, and manufacturing methods.
The technical problem of the present invention is to pay attention to such a problem, and by making it made of thick paper, it is thin and bulky, small and suitable for carrying, and can be manufactured at low cost. The tightness of the floss is improved when it is formed, and a simple interdental cleaning tool that does not deform the bow shape is realized.

The technical problem of the present invention is solved by the following means. The first aspect of the present invention is a structure in which a thread for floss is sandwiched between two thick papers having holes for flossing, and the floss is folded in half around the floss for use. It is a characteristic simple interdental cleaning tool.

Claim 2 is a simple interdental cleaning tool adhered with a floss thread sandwiched between two sheets of cardboard with holes for flossing, folded in half around the floss, and bowed. A simple interdental cleaning characterized by that, in the two-folded portion, the gap between the two thick papers or the gap between the two sheets is compressed and reduced to make it difficult for the floss to come off, and the tension does not loosen. How to use the ingredients.

According to claim 3, the floss is bonded between two sheets of thick paper having a hole for flossing with a thread for floss sandwiched in the diameter direction of the hole to integrate the three and the floss. This is a method for manufacturing a simple interdental cleaning tool, which is characterized in that it can be folded in half at the center to form a structure.

A fourth aspect of the present invention is the method for manufacturing a simple interdental cleaning tool according to claim 3, wherein the crease frame descends on the floss and crushes the floss to facilitate folding in half.

As of claim 1, Yes bonded while sandwiching the yarn for floss between two cardboard with a hole to tension the floss, a structure in which use overlapping with clamshell around the floss because, when you structure overlaid with two-fold in the center the full loss, tightening the floss to become a core, we floss is difficult to slip. This action and effect is a major feature.

When a simple interdental cleaning tool adhered with a floss thread sandwiched between two thick papers with holes for flossing as in claim 2 is folded in half around the floss. In addition, at the double-folded part, the space between the two thick papers or the gap between each paper is compressed and reduced, making it difficult for the floss to come out. Also, the tension will not loosen easily.

Next, as in claim 3, the floss thread is sandwiched between two thick paper sheets having holes for flossing in the diameter direction of the holes, and the three are integrated. At the same time, since the structure is formed by folding the floss in half, when the floss is folded in half, the space between the two thick papers or the gap between the two sheets is compressed and reduced in the folded portion. However, the floss is hard to loosen and hard to come off.

Finally, as in claim 4, the crease frame descends and crushes the floss to make it easier to fold in half, which makes it easier to fold in half and allows you to fold in half at the correct position. It becomes.

It is a perspective view which shows the basic structure of the simple interdental cleaning tool by this invention in a unit unit. It is a perspective view which shows the usage of the unit of the simple interdental cleaning tool by this invention. 3A and 3B are views for sequentially explaining a method for manufacturing a simple interdental cleaning tool of the present invention, and FIG. 3 is a plan view of a lower mold. It is a plan view and a bottom view of the upper mold. It is a top view after molding the holder paper. It is a top view of the state where the floss thread is stretched. It is a top view which put and adhered the holder upper paper on the floss thread. It is a horizontal sectional view of a perforation mosquito jitter over position carrying the perforation unit. It is a top view and a bottom view of a perforation unit. It is a top view before burning off the tip of floss f. It is a plan view of one set consisting of units of four simple interdental cleaner.

Next, an embodiment will be described of how the simple interdental cleaning tool according to the present invention is practically embodied. FIG. 1 is a perspective view showing a basic configuration of a simple interdental cleaning tool according to the present invention, and is a state after manufacturing. That is, as shown in FIG. 1, the floss thread f is sandwiched between two holder cardboards P1 and P2 having substantially semicircular holes h1 and h2 with the floss f sandwiched between them. As shown in FIG. 2, the floss f is folded in half around the floss f and stacked. It is used by folding it in half, stacking it, and gripping it with a finger. The handle is two protruding parts F1 and F2 that are folded in half and sandwiched between the thumb and the index finger / middle finger. Therefore, the handles F1 and F2 are sandwiched between the fingers and gripped, and the floss f is inserted between the adjacent teeth and slid back and forth to clean the interdental or interdental surface.

In this case, a strong tension is generated and acts on the floss f, but since the floss f is sandwiched between the two thick papers P1 and P2 and adhered, the thick paper portion is folded in half around the floss f. At the time of stacking, the space between the two thick papers or the gap between the two thick papers is compressed and reduced in the double-folded portion, so that the tightness is naturally improved, and the floss f is hard to come off and does not loosen. Therefore, it can be used with peace of mind, and there is no risk of it extending or loosening.
When the floss f is separated from the floss f of another simple interdental cleaning tool, a spherical portion B is formed at the end when the floss f is burned off by heating, so that the spherical portion B acts as a stopper and described above. Loosening prevention is more reliable. In the expanded state before folding the handles F1 and F2 around the floss f, the area is large, so that printing is possible and it is suitable for printing advertisements.

Moreover, since it is small and thin, it is not bulky, it is easy to carry, and because it is made of cardboard, it can be manufactured at low cost.
In particular, the periphery of the floss f is pressure-bonded with the floss thread F sandwiched between two holder cardboards P1 and P2 having substantially semicircular holes h1 and h2 sandwiching the floss f. Therefore, there is no risk of getting in the way when brushing and cleaning the space between teeth and the surface of teeth with floss f. The holes h1 and h2 do not have to be semicircular, and may have other shapes.

FIG. 3 and the following are views for sequentially explaining a method for manufacturing the simple interdental cleaning tool of the present invention , and FIG. 3 is a plan view of a lower mold. Cut off with your eyes. That is, in the illustrated example, four sets of integrated simple interdental cleaning tools are punched and molded at the same time. First, as shown in FIG. 3, the upper molds 3 and 4 of FIG. 4 are placed on the lower molds 1 and 2 having four semicircular holes h1 and h2 with the holder cardboard placed. FIG. 4 (1) is a plan view of the upper molds 3 and 4, and when the lower surface thereof is viewed, the cutting edges of the cutters C1 ..., C2 ... Are exposed on the lower surface of the upper molds 3 and 4, as shown in FIG. 4 (2). is doing. The periphery of the cutters C1 ..., C2 ... Is sandwiched between black rubber G with a slight gap. Therefore, when the upper molds 3 and 4 are lowered, the cutters C1 ..., C2 cut the thick paper, and two sets of holder thick paper remain. Since this holder cardboard is bonded in two layers, it is necessary to cut twice as many sheets.

Next, as shown in FIG. 5, two sets of lower paper are positioned, and the thread F for floss f is stretched on the paper as shown in FIG. 6, and the upper holder paper is as shown in FIG. Is placed, and then the floss thread F is sandwiched between the upper and lower papers and adhered.
Since they are separated one by one at the time of use, perforations for that purpose are provided in advance. As shown in FIG. 8, when the perforation unit 5 is placed and pushed down, the cross-shaped perforation cutters 6 and 7 are lowered to make perforations. At this time, since the crease frames 8 and 9 are provided integrally with the perforation unit 5, the crease frames 8 and 9 descend on the floss f and crush them to facilitate folding in half. Further, since the cutting edge of the perforation cutter 6 in the direction orthogonal to the floss f is arranged at the position C where the floss thread F is cut, the floss thread F is separated for each unit.

FIG. 9 shows the entire perforation unit 5, (1) is a plan view, and (2) is a view of the lower surface, which is black with gaps on both sides so as to sandwich the perforated cutters 6 and 7. Since the rubber G is provided, the cutters 6 and 7 are lowered against the elasticity to make perforations so that the cutters 6 and 7 can be easily separated.
Finally, as shown in FIG. 10, the tip of the floss thread F is burnt off in order to form the floss f, and as shown in FIG. 11, a sphere B is formed to prevent the floss thread from coming off. Reference numerals 7 and 8 are perforations for separating each unit.

As described above, the structure is such that the floss thread is sandwiched between two holder cardboards with almost circular holes and pressure-bonded, and the floss is folded in half around the floss. Because it is thin, it is thin and not bulky, and it is small and suitable for carrying. Moreover, since it is made of paper and has a simple structure, it can be manufactured at low cost. Since the outer end of the floss is burnt out to form a spherical shape, it serves as a stopper and does not easily come off. In particular, when the floss is folded in half around the floss, the space between the two sheets or the gap between the two papers is compressed in the folded portion to naturally improve the tightness and make it difficult for the floss to come off. Therefore, unlike the one made of synthetic resin, it is not deformed by the tension and the tension is lowered to impair the sliding of the tooth surface.
