Description

Floss Toothpick

The field of technology.

The utility model relates to the field of oral hygiene and dental care, and is intended for cleaning interdental spaces.

The prior art.

There are many devices for cleaning teeth and interdental joints. For a long time toothpicks in the form of a firm or spring stick were used to clean the interdental spaces. Examples are toothpicks according to EPO application No. 0354352 (1990), according to US patents No. 4832061 (1989) and No. 5283924 (1993). They offered various options for pointed rods, and to increase the cleaning efficiency, they were made elastic, flexible, adjustable in length and thickness, their surface was made rough, and at the same time, therapeutic preparations were introduced into the interdental space, etc. These toothpicks quite well remove large elements stuck between the teeth. However, they loosen the teeth, remove small elements worse, and it is difficult to clean the rest of the teeth, since the pointed rods (having a noticeable thickness) do not penetrate between the densely standing teeth and the back walls of the teeth. The cleaning process is long - it is necessary to treat the entire surface of each tooth with a thin cleaning end.

More effective are toothpicks in the form of a thread or similar very flexible material. They can penetrate into narrow interdental spaces and, in addition, cover and clean immediately a significant part of the tooth surface. Examples of modern toothpicks of this type are US Pat. Nos. 5,284,169 (1992), 5,280,797 (1994), 5,222,510 (1993), 5,224,501 (1993), 483,032 (1989), 4832062 (1989), 4832063 (1989) 4817642 (1989) 4817642 (1989), WO publication No. 94/00075 (1994). The development of designs of toothpicks with a thread came from the simplest threads that the user (person) holds with his hands, to extremely complex devices. Direct use of a single thread is inconvenient and non-genic.

MKL.6A61S15 / 00

US patent No. 4832063 (1989) proposes a guide for the thread, which is inserted into the interdental space. The guide has an elastic hook-like element, which is held behind the tooth selected for cleaning, covering the latter, and then bring it forward from the tooth. An elongated string is attached to the guide. The string has small spikes that remove plaque and tartar. The device is not plagienic, its use leads to loosening of the teeth. US patent No. 5224501 (1993) describes a device for one-time brushing with two thin elongated handles, to the ends of which is attached a thread for cleaning the interdental spaces. The outer ends of the handles are free, they are lever-manipulated by the thread inserted between the teeth. Handles are held by hands, without putting fingers into the mouth. This device loosens teeth less, but is also unhygienic. Its use occupies both hands, which sometimes need to be inserted into the mouth for threading. US patent No. 5222510 (1993) provides a very simple device in the form of an open ring made of an elastic material and forming a plane. A cleaning thread is inserted into the open portion of the ring. The size of the ring and the tension of the floss is adjustable for each user so that the ring is firmly put on the finger, with which the floss is inserted between the teeth. The device is more convenient than the previous one and is controlled by only one finger.

Later on, more simple and genital toothpicks were developed. They differ not only by the presence of a handle with a thread holder, means of thread tension and thread cleaners, but also by manual or automatic thread pulling means - for changing its working part for disinfection purposes. The greatest difficulty is disinfection problems. In the process, a large number of microbes and other harmful elements of bioflora from the bands ™ of the human mouth gets onto the thread. To protect this, the working part of the thread must be periodically treated with disinfectants, or the thread should be changed regularly. Disinfection is complex and can cause aesthetic irritation and allergic reactions in humans. A regular change of thread is also difficult and difficult to achieve by the consumer’s own forces. Therefore, real flossing toothpicks are very complex. In particular, cleaning according to US Pat. No. 5,280,797 (A61C15 / 00, claimed 1993) is a handle with a U-shaped thread holder at the end.

A thread is stretched between the projections of the thread holder, which is movably stretched through the side elements of the thread holder - from the rack on which the unused thread is wound, to the rack where the used thread is wound. The thread passes through the toothpick handle, which has a device for moving the thread inside. Therefore, the handle is voluminous and rigid. The thread is stretched across the longitudinal axis of the handle.

Toothpick US Pat. No. 4,830,032 (A61C15 / 00, 1989) uses the same principle. It contains a handle into which the motor is inserted, which drives the pin. A U-shaped working part is put on the pin, with ends of different lengths, between which a cleaning thread is stretched. The handle is voluminous and rigid. The thread is stretched across the axis of the handle.

Toothpick according to publication WO No. 94/0005 (А61С15 / 04, 1994) is a fully automatic device with a drive. It contains an elongated hull handle with a protruding thin bar ending in a forked (U-shaped) tip. The elongated housing-handle contains inside two spools of thread, a set of gears, switches and an electric motor with a set of batteries or a transformer. The thread passes between two branches of the fork tip and is wound on two spools, one for the unused part of the thread, the second for the used part. The possibility of reciprocating movement of the thread between the mentioned branches and the mzhzuboznoe gap. The handle is voluminous, rigid. The thread is stretched across the longitudinal axis of the handle.

As can be seen from the descriptions, the listed devices are complex and, accordingly, expensive for the mass consumer. In addition, they do not provide complete cleaning. Indeed, the procedure for brushing your teeth requires the use of at least two devices - a stick / and floss. The floss cleans the surfaces between the teeth, changing the angle of its inclination with respect to the sides of the tooth. To clean the sides of the tooth, you also need a stick-toothpick, with which changing the angle and outlining the border of the mucous membrane of the tooth, clean the sides of the teeth. The absence of one of the tgenic accessories (sticks) leads to incomplete cleaning.

The closest analogue of the proposed solution (the prototype of the utility model) for most essential features is a toothpick according to US patent No. 5280797 Dental floss tool (claimed January 25, 1993,

published on January 25, 1994, and in the Journal of Inventions of the World, Issue 7, No. 13, 1995). As already described above, it contains a rigid volume handle, at the end of which there is a U-shaped thread holder, between the ends of which a cleaning thread is stretched, and the thread is stretched across the axis of the handle. The thread is stretched through the ends of the thread holder and is rewound from the rack with the unused portion of the thread to the rack with the used portion of the thread. The thread passes through the handle of the toothpick, in which a device is installed, pulling the thread.

Like other analogues, the described toothpick is complex, expensive and does not provide complete cleaning without the use of additional devices. It is inconvenient to introduce and manipulate the thread into the mouth, since the thread is stretched across the oal of the handles. With this orientation, to insert the thread into the interdental spaces, the handle must be placed on the side of the mouth, across the interdental spaces. This painfully sprains the corners of the mouth. It is especially difficult to clean back teeth and back sides of teeth.

The task of the utility model.

The objective of the utility model is to simplify toothpicks, improve ease of use and quality of toothbrushing.

The solution of the problem.

The problem is solved by that. that the known toothpick with a thread containing a handle, at one end of which there is a U-shaped thread holder with a thread fixed in it, significant changes and additions have been made, namely:

-, the handle and thread holder are made flat and placed in the same plane, - the second end of the handle is pointed.

In addition, the handle may be made of a soft material.

In addition, to maintain the shape, the thickness of the handle can be no less than 3 times less than its width. In addition, the thread can be installed at an angle of 15-30 fades to the axis of the handle.

In addition, the handle may have a stiffener located between the pointed end and the thread holder.

Disclosure of the essence of the utility model.

The essence of the utility model is illustrated by the figure below, which shows an example of a toothpick with a thread - a) side view, b) top view in the initial position, c) top view after izp / 1ba (option).

The following notation is used in the figure:

1 - handle, 2 - thread, 3 - U-shaped thread holder, 4 - pointed end of the handle 1,5- places of possible bending of the handle, 6 - stiffener.

The toothpick consists of a flat handle 1, at one end of which a U-shaped thread holder 3 is made with a tensioned thread 2. Attaching the thread to the ends

The thread holder can be made, for example, through the through holes at the indicated ends, followed by press fitting. To strengthen the fastening at the ends of the thread, thickenings can be made, for example, knots. The thread holder 3 is flat, it is made at the same time with the handle 1 and is located in the same plane. The width of the handles and the side elements of the U-shaped thread holder 3 is not less than three times their thickness. The second end 4 of the handle 1 is pointed. Between the thread holder 3 and the pointed end 4 of the handle there is a stiffener 6. For ease of holding, the stiffener can be made with a corrugated surface. The corrugation can be applied to the narrow sides of the handle. Sections 5 of the handle 1 in front of the thread holder 3 and in front of the pointed end 4 are more flexible than the middle of the handle. They can be bent by the user more than 90 degrees relative to the plane of the handle.

The thread can be applied therapeutic, prophylactic or p / 1p / 1enic pokriple, for example - antiphippic during periods of expected seasonal epidemics.

Toothpick is used as follows. Toothpick with thread 2 is held by the corrugated surface of the stiffening ribs 6 with fingers, cleaning

with the pointed end 4, the lateral spheres of the tooth and outlining the mucous surface of the tooth. Then, turning the toothpick with the thread holder on the other side to the mouth, clean the lateral (front and posterolateral) surfaces of the tooth. Bending the handle elements in places 5, the consumer orientates the thread 2 and the pointed end 4 of the handle for convenient cleaning of hard-to-reach places inside the oral cavity. After cleaning part of the teeth, the toothpick can be straightened and bent otherwise for more convenient access to other teeth. It should be noted that the handle bends only relative to its

l (flatness, since its width is not less than three times the thickness.

the opposite bending of the lateral components of the thread holder under the influence of the thread tension is eliminated. Toothpick is for single use only.

Thus, the claimed design of a toothpick with floss is sufficient to carry out cheap, semi-surgical, convenient and complete toothbrushing.

Industrial applicability.

The claimed utility model can no doubt be implemented at present by available standard means. The starting materials (flexible plgenic plastics, threads, coating) and machines for their processing are well known, relatively cheap and affordable.

The claimed utility model is made and used by the applicant at Prosperity LLC. High-impact polystyrene plastics, nylon threads treated with antiseptic and menthol are used. Production is made on molding machines. Tests fully confirmed the achievement of the objectives - the product turned out to be much simpler than analogues, it cleans teeth and interdental spaces more conveniently and better. Experimental batches of toothpicks with thread have passed massive successful testing by consumers in Moscow, St. Petersburg, Belarus and Ukraine. It also showed that the use of the declared toothpicks with thread is very convenient, its shape is chosen by the consumer himself for his individual needs. The declared toothpick with a thread is maximally githenic, because the product (unlike analogues), due to its cheapness, is intended for disposable or rather short-term use. And before use, it is stored in a tightly sealed package. The inventive toothpick with thread miniature, flat, fits comfortably in your pocket or notebook and has a more attractive original appearance.

Thus, the claimed utility model is new, useful and industrially applicable, i.e. satisfies all the requirements for utility models.
