The gear is rotatably provided in the plug together with the shaft, and the gear engages with the gear to limit the rotational direction of the gear to only one direction, and the Riha,
The second boob is installed at one end of the shaft and outside the casing to receive dental floss before being sent to the application section, and the second boob receives dental floss from the application section. The knob is provided at the other end of the casing at the other end of the casing, and the knob is provided at the other end of the casing. It is provided at the one end of the seat 71- to rotate the first and second boots.

EXAMPLES The basic components of the dental floss application and retention device according to the present invention will be described below with reference to the drawings.
and a handle indicated generally by numeral 1.

The handle 1 comprises a tubular casing 2, which is attached to the handle 1 to hold the dental floss, and a winder mechanism 3, generally indicated by the reference numeral 3, for unwinding the dental floss from the casing 2.

It has the same shape as a conventional toothbrush except for the generally C-shaped head 4, which forms the application part of the two-piece device. The head 4 is one set.

Slightly inclined arched arms 5 and 6 extending forward;
including. As best shown in FIGS. 2 and 3, each of the arms 5 and 6 has a nozzle 8 on its outer periphery for receiving and holding dental floss 9. As best shown in FIGS. The handle 1 extends upwardly beyond the top of the groove 8 at the back of the head 4.

Includes an open groove 10 (FIG. 2) for dental floss 9. A set of slots 13 are provided on the top back of the handle 1 for introducing dental floss 9 into the arm 5 and leading it out from the arm 6.

The casing 2 is made of a transparent rigid resin tube having an open lower end 15 and an inclined open upper end.

A spool 17 carrying dental floss 9 is inserted from the lower end of the casing 2. The spool 17 has a disk 19 at its upper end and a disk 20 near its lower end.

It consists of 211 feet 18 in the form of a rod. disk 19
, 20 and the casing 2 so that the spool 17 can easily slide within the casing 2.

The disc 20 is in a state J3 with the spool 17 fully inserted into the casing 2 and closes the lower end of the casing.

The lower end of the shaft 18 extends downwardly beyond the disk 20 to facilitate manual insertion and withdrawal of the spool 1'7. The spool 17 is held within the casing 2 by a small soi clip 22. The wire clip 22 has a short spring wire and extends outward from between the casing 2 and the handle 1. When pushing the spool 17 into the casing 2, it is sufficient to push the clip 22 to one side. Spool 17
Once inserted, the clip 22 is in pressure contact with the gauging 2 and the lower end of the spool 17.

The spool 17 rotates within the casing 2 while dispensing the dental floss.

The dental floss 9 is fed out from an opening 24 provided on one side of the casing 2 near the upper end 16. The dental floss 9 exits through the opening 24 and is wrapped around the drive pulley 25 three or four times before extending upwardly towards the back of the upper end of the handle 1 and passing through the slot 13 closer to the arm 5. into the groove 8 in the arm, around the arm 5, across the gap between the arms 5 and 6 to the groove 8 in the arm 6, and after passing around the arm 6, through the other slot 13 and 9 turns. The control pulley 26 is reached.

The winder mechanism 3 shown in FIG. 4 includes a plug 28 that closes the casing 2. The winder mechanism 3 shown in FIG. The lower end of the plug 28 is bifurcated. Two gears are attached to a shaft 30 that protrudes from the upper end of the casing 2. The gear 29 rotates with the shirt 30 between the arms 31 of the plug 28.

A metal pawl 33 extends upward from the lower side through an opening (not shown) in the back of the casing 2 and is mated with the small teeth 29. This causes the gear 29 to rotate only in one direction, that is, in the direction of dispensing the dental floss, and not in the opposite direction. Drive pulley 2
5 is a drive disk and r disk 3 at one end of Shireff l-30.
It is installed adjacent to 4. The disc 34 has a transverse groove 35, which makes it easy to pick and turn the disc by hand. The take-up pulley 26 is connected to the shaft 3
゜It is fixed at the other end. Therefore, when the disk 34 is rotated, the drive pulley 25. Gear 29 and winding pulley 2
G will rotate in the same direction.

When applying dental floss and using the holding device shown in Figures 1 to 4, first, spool 1
Wrap dental 70s around 7.

Next, the dental floss 9 is wound several centimeters from the spool 17, and the free end of the dental floss is inserted into the opening 2. /I
A flexible wire threader (not shown) inserted into the casing 2 through the wire f] is tied to one end of the flexible wire threader (not shown). and pulling the dental floss through the opening 24 while simultaneously inserting the spool 17 into the casing 2.
Prevents dental floss from accumulating at the front of the spool. Place the dental floss on the IC as described above and attach it to arm 5.
and 6, and then wrap it around the pulley 26 in the direction of rotation. A small pin (not shown) in the groove of the bushing 26 facilitates the installation of dental floss into the bushing. The dental 70 is wrapped around the pin and fixed to the pulley with a relatively small number of turns.

In this state, the dental floss application and retention device is ready for use. First, in order to avoid moving the dental floss stretched between arms 5 and 6, rotate the disc 34. This causes the dental 70 to move forward. When the take-up pulley 26 becomes full, the dental floss is cut between this pulley and the arm 6, the used dental floss is removed from the pulley 26, and the free end of the unused dental floss is removed. Connect to pulley 26 again.

In another embodiment of the invention (not shown).

Longitudinal ribs for sliding into the open upper end 16 of the casing 2 are provided on both sides of the arm 31.

Therefore, the winder mechanism 3 can be easily removed from the casing 2 and repaired.

In another embodiment of the invention shown in FIG. 5, instead of the handle 1 and the casing 2, a tubular casing 3 is provided.
5 is used, and this tubular casing 35 has J at one end.
5 to form the lower ends of both the handle and the tubular casing. The upper end of the handle (not shown) with arms spaced d3 apart from each other is made in one piece with the casing 35 and is substantially identical to the device shown in FIGS. 1 to 4. In this example, a lever 36 is used in place of the clip 22 for holding the subroutine within the casing 35. The lower end 37 of the casing 35 is inclined with respect to a plane perpendicular to the longitudinal direction IIi+ of the casing. When the spool 40 is fully inserted, the enlarged lower end 39 of the spool will protrude from the casing 35 so that the spool can be intercropped by hand. lever 36
It is integrated with the gluing 35 and has slits 4 on both sides of 9.
The housing 35 is made of a wire material separated from the other parts of the housing 35 by 1. The freedom of the lever 36 @i43 is such that the casing 35 can be pulled out by hand.
It protrudes somewhat beyond the end 39 of. To retain the spool 40 within the casing 35, the n-section 44 of the lever 36 typically engages a disc 45 near the lower end of the spool. If the spool 40 is not removed, the lever 36 is rotated outward to release the disc 45.

As shown in FIG. 6, spool 40 includes shirt 1-47, around which dental 70 spool 9 is wound. In this case, the previously mentioned plug 28 is replaced by a cylindrical plug 48, which has a laterally extending rectangular cavity 49 for accommodating the gear wheel 29. Then, instead of the disc 34, another form of knob is used, namely a flat handle 50, and the pulleys 2G and 5
2 and is attached to the shaft 30.

Pulley 52 is comprised of the inner surface of handle 50 and a disk coupled thereto. A square lug 53 projects downward from the bottom 54 of the pulley 4-8.

This engages the generally cross-shaped upper end 5G of the spool 40. The upper end 56 of the spool 40, the lug 5
3 constitutes one lock.

J That is, when the spool 40 is directed upward and pressed against the plug 48, the lug 53 is pressed against the upper end 5 of the spool.
The crowding between the two wooden arms at 6 results in the spool being unable to rotate more than one revolution. In other words,
The spool will be locked. When the spool 40 is slightly pulled out of the casing 35, the spool is released from the lugs 53.

Be able to rotate freely.
