TOOTH BRUSH

The invention refers to a single use tooth brush, which have some bristles that may contact a cleaning medium which is kept in one section of the brush.

We know there are tooth brushes having some sections which form the brush itself and its handle. These sections are joined together by a middle section. A tank containing a cleaning medium is provided in the handle. A pumping subassembly is used for feeding the bristly section of the brush with a cleaning medium. The posterior pipe, the anterior pipe, the tank, the casing of the pumping subassembly and the middle section represents the elements of an essentially continuous structure. A cylindrical body is provided in one slot of the casing which is open at the top, but covered with a flexible membrane placed on the casing. The membrane contacts a spring. An inlet and respectively an outlet valve are assembled in front of the pipes. A breather that separates the environment and the tank is assembled in the casing.

The disadvantages of this type of tooth brushes, mostly when the cleaning medium is of a quantity that allows only a single use, consist in the fact that they have a approximately complicated design, mainly as a result of the use of pumping subassembly with membrane. This requires a special rheology of the cleaning medium so that it may be pumped through the inlet and outlet valves without clogging them. Another disadvantage is that tooth brushes are relatively big in handle area.

The technical problem resolved by the invention consists in simplifying the assembly of a tooth brush for one single use, which should be light and clean. These requirements are fulfilled by the tooth brush, according to the invention. The brush is characterized in each designing variant by all that is described in the attached claims.

According to the invention, the tooth brush obviates the above mentioned disadvantages, because it has a body with a short anterior port. The tank containing the cleaning medium is designed on this section, on which it has been previously provided a calibrated orifice. This orifice is in contact with the tank which is placed before the bristles and bordered in the back and laterally by an amount if them. A tight piston is provided in the tank and it is continued with a rod that partially goes through a long channel provided in a posterior long section of the body communicating to the outside. The rod has a slot at a posterior end, where we may introduce a sharp point of a lengthening piece provided with a push button. This lengthening piece is designed and kept in an elongated slot on an inferior side of the posterior section and the button is placed in a hole.

The tooth brush, according to the invention, conform to another designing variant, consist of a body and an inferior all that delimits the tank where is located the above mentioned piston. There is a long slot provided in the body, which is delimited in length by some anterior and posterior arms, closed by some areas of the waif such as: an anterior concave one and a posterior right one. The last one is provided with an elongated slot in the posterior area, through which a push and guiding button of the above mentioned rode gets outside. Its move in one direction is limited by the contact with the posterior arm.

The tooth brush, according to the invention, conform to another designing variant, consist of a body in whose long posterior area, in the front side, is provided the tank where is located the above mentioned piston. This is in connection with a short channel ended with the calibrated orifice situated in the back side of the above mentioned bristles. It is bordered in the front and in the two sides by a number of these bristles. The channel gets through a middle area and partly through an anterior section of the body. The mentioned push and guiding button is placed in an elongated slot through which it gets outside. The slot is on the top of the body located in front of a hole in which the mentioned rod is introduced in case the tank is filled with a cleaning medium.

The tooth brush, according to the invention, conform to another designing variant, consist of a body having some anterior and middle short areas and respectively a posterior long one. A tank is placed in the middle area, on the inner side of the body, and it is continued in the anterior area with a slim tube that penetrates and it is laterally and frontally bordered by a number of the bristles fixed in the anterior area.

The tank represents a distinct assembly that it is first filled with cleaning medium and then glued on the back area of the bristly section of the brush. The discharging tube is sealed at one end. The seal opens when pushing the tank which is made of an antiseptic material and it's easy to be got out of its shape.

The tooth brush, according to the invention, may have the tank and respectively the piston delimitated by a foil, made of a material having antiseptic qualities, such as an aluminum-base alloy that the cleaning medium is in contact with.

The tooth brush, according to the invention, is designed for a single use and may be easily adapted to different dimensions according to different situations of use such as: a home use for adults or children when teaching hygiene lessons, on holidays or recreation places.

The tooth brush, according to the invention, may be especially used when it is designed in one of the above mentioned assembling variants: when it has a push/sliding button provided on the superior or inferior side of the body; when it has a tank that may be got out of its shape. It may be used by handicapped people who can not see and who use their touch. Especial designs of the component parts of the brush, according to the invention, allow the above mentioned situations when we need to use it.

The tooth brush has the following advantages, according to the invention:

- has a relatively simple design,

- allows a single light and clean use,

- it is safe,

- may be successfully used by people with disabilities, who can not see and they can use only their touch or smell.

There are further given four examples of designing the tooth brush, according to the invention (figures 1 10 that represents):

- fig.l - longitudinal section through a body of a tooth brush, according to the invention

- fig. 2 - inferior view of a posterior area of the body;

- fig. 3 - top view of an anterior area of the body;

- fig. 9 - longitudinal section through a body of a brush, according to the invention differently designed;

- fig. 10 — longitudinal section through a body of a brush, according to the invention differently designed.

The tooth brush, according to the invention, is made of a body 1 provided with some sections (areas) a and b, a posterior long one and an anterior short one.

In the anterior section b, a tank c is provided and a cleaning medium 2 is filled in it. The tank contacts the exterior through an orifice d which is calibrated. This orifice is located in front of b area and it is bordered by some bristles 3 on the sides and in the back side.

The bristles are fixed in a superior area e of the b section. The calibrated orifice d it is located at the front end of the tank c, so that when actuating the piston 5, the whole quantity of cleaning medium may be pulled out of the tank.

The calibrated d orifice is sealed by a flat seal, which is known and that may be removed by hand, situation which is not shown in the figures, or may be removed using a sharp f point of a cylindrical or shaped lengthener 4 that is also provided with a push button g.

The cleaning medium 2 is introduced in the tank c through the calibrated orifice d. As soon as it fills the tank c, the medium moves a tight piston 5 in it, whose stroke is limited at an arm h. This is placed at the posterior of tank c in a middle section i of the body 1 that connects the section a and b.

The piston 5 is continued with a rod 6. This rod goes partially through a channel X which is long and it is provided in the long superior section a and which contacts the outside area. The rod 6 has a slot 1 provided at a posterior end k.

An elongated open slot n in which it is provided the lengthener 4 is designed in an inferior m section of the posterior a section. The slot n is continued with a hole g, in the proximity of a posterior end o of the section a, where partially enters the g push button.

The lengthener 4 is hold in the slot n using some known seals, made for example of a plastic material, having the contact surface with section 1, a glue, situation which is not shown in the figures.

Two tangible prominences 16 are provided at the half of the 4 rod length for guiding in the channel j., for a better set in the channel n, and also in order to allot the cleaning medium into two equal quantities.

When starting the filling of the c tank with the cleaning medium 2, the piston 5 is partially situated in front of the calibrated d orifice. As soon as the medium 2 gets in the tank c, the piston 5 is moved till it reaches the arm h. In the same time, the rod 6 is .moved .and it is jointly with piston 5, inside the x channel which lengths till reaches the end o.

The capacity of the tank c may be from 0.5 to 1.5 ml, cleaning medium enough for an efficient brushing.

In order to use it, we have to release the lengthener 4, and using the point f we open the calibrated orifice d which is covered by a seal. Afterwards, we have to connect the lengthener 4 with rode 6 by penetrating the point f in the slot 1 and moving the lengthener 4 and the rode 6 by pushing the button g, situated on the external side of the body 1. That determines the sliding of the piston 5 inside the tank c and the cleaning medium 2 gets out through the calibrated orifice d.

The cleaning medium 2 may be got out of the tank c through the calibrated orifice d in many dosage quantities.

The lengthener 4 provided with the point f may be used as a toothpick, if there is needed.

In order to keep their hygienically clean before use, the body 1 and the lengthener 4 are packed in a plastic foil which is tightly closed. The j. channel is closed with another flat seal at the posterior end, situation not shown in the figures.

The tooth brush, according to the invention, in another designing variant, contains a body 7, having some sections g, r, s: a short anterior one, a short middle, shaped one and respectively a posterior long one.

In the body 7, the sections fl and r and partially the s section are provided with a long slot t which is open and limited in length by some anterior and posterior arms u and v. The slot t is closed by an inferior wall 8, provided with an anterior concave section w limited by an arm x and a x flat section.

The wall 8 is glued on the body 7 and it forms a tank z in front of the anterior w section. It is placed in the anterior a section where it is assembled a tight piston 9. The last is connected to a rode 10, designed in the slot t, ended with a pushing and guiding button 11, provided in an elongated slot Λ_, designed in the wall 8 in the flat section, through which the hole t gets to the outside. The button 11 gets out of the section y,.

Near an end b\ in the g, section, there is an orifice cΛ in front, which is calibrated and bordered on its sides and at its back by the bristles 3. They are fixed in the anterior a section.

The tank z is filled with cleaning medium 2. This is introduced through the calibrated orifice cf and it moves the piston 9. The last one is at first partially placed in front of the orifice c\ till this one gets in contact with the arm x. Then a flat seal closes the slot aΛ and the c" orifice (which is not shown in the figure). The button 11 may be ensured against the undesirable maneuver using another seal which is known but is not represented in the figures.

The capacity of tank z may be of 0.5 to 1.5 ml of cleaning medium 2, a quantity that is enough for only one use.

In case we need to allot the cleaning medium 2 quantity in two equal quantities, on both sides of the slot al are provided two tangible prominences 17.

In order to keep them hygienically clean before use, the body 7 and the wall 8 are packed in a plastic foil, tightly closed.

The tooth brush, according to the invention, in another designing variant, has a body 12 made of some parts dT, e\ and f : short anterior one, middle and respectively long posterior ones. • . .

F side is provided in the front with a tank g\ This is in connection to a short channel hi which ends up with an P_calibrated orifice. This orifice is bordered on its sides and in the front by a number of bristles 3, fixed in (P section. The hi channel gets through the middle el section and partially through <P_ section.

The tank gl is limited by some walls jl and kl_: shaped in front and respectively flat in the back section. There is a piston 13 inside of it, connected to a rod 14 that ends with a pushing and guiding button 15. The last one is placed in an elongated slot Undesigned on top of the body 12 and located in front of a hole nil.. In this hole, if the tank gl is full with cleaning medium 2, we place the rod 14. The button 15 contacts a posterior arm m?, that delimitates the hole m£, getting out of the body 12.

The piston 13 has an anterior surface g\, identically shaped with the anterior wall i, that gets in contact when it starts the filling of the tank g£ with the cleaning medium 2. This action is performed through the calibrated i orifice.

When the filling of the gl tank has finished, the orifice P it's tightly closed, and the slot F, too. The button 15 is closed with another seal, which is not shown in the figures.

The capacity of the tank may be of 0,5 ... 1,5 ml of cleaning medium 2, a quantity that is enough for only one brushing.

If we need to allot the medium quantity into two equal quantities, on both sides of the slot 1, there are provided two tangible prominences.

The tooth brush, according to the invention, in another designing variant, consists of a body 19 having some sections (PJ., e^ and P^: short anterior and middle and respectively a long posterior one. In the middle section e^, on its inside area, there is a tank c^, provided, which is continued in the front with a slim tube 20, that penetrates. This one is bordered at the sides and in front, by a number of bristles 3, which are fixed in the <F_1 section.

The tank c^ is a distinct assembly that after it has been filled with the cleaning medium 2, is glued on the e^. section of the brush. The tube 20 is closed at one end with a seal that opens when pushing the tank c^., made of an antiseptic material and easy to be got out of its shape.

The capacity of the tank c^ is of 0,5 ...1,5 ml of cleaning medium, tooth paste or gel, a quantity which is enough for one use.

The tanks c, z, g and c^ may be limited by a foil made of a material having antiseptic properties, such as an aluminum- based alloy, like one that contacts the cleaning medium 2. The same material may be used in order to cover any of the pistons 5, 9 and 13.

The bodies 1, 7, 12 and 19, and also the wall no. 8, may be obtained by being cast out of a plastic material, glass or they may be processed of a wooden stuff or obtained by pressing waste of wooden stuff that has been previously antiseptically treated. In this last case, the resulted waste obtained as a result of an one single use of the brush may be directly burnt, without involving environmental problems.
