DE19704920A1 - Combined toothbrush and tooth cleaning gel dispenser - Google Patents

Abstract

The unit (1) has a connection chamber between the brush and the dispenser container. The chamber has an insert made of soft rubber, to permit opening and closing of an air channel. Pressure applied to the container deforms the rubber and closes the channel, and tooth gel can flow into an outlet channel. When the pressure is removed, the air channel is opened and return flow of the gel is prevented. The contents of the container can be checked via a visibility strip. If the container consists of transparent material, any free space can be used for advertising. The device comes in different colours.

Description

Field of application: easy-to-use combination in dental hygiene

State of the art: the combination of toothbrush and toothpaste is patented in several fonts (see patent numbers 9017551, 9107530 or 29501338 and other fonts in recent years).

Disadvantage: The previous attempts at the combination mostly see technically complicated devices Manufacturing or toothpaste transport (see state of the art) or go totally from today's manufacturing standard. (see dissolving toothpaste under Pat.No. 9403213 In addition, attempts are made to achieve savings on the dispenser or brush (see patent no. 910753), which certainly cannot be in the interest of the manufacturing industry. Last but not least All previous attempts have failed to achieve simple manufacture with simple operation combine, since either manufacturing costs are too high or still operated with two hands respectively.

Object of the invention: creating a combination with low manufacturing costs, one-handed service (here especially for use by the disabled or small children) and the guarantee of a Even sales of toothpaste and toothbrushes.

Solution of the task: The combination is easy by using special plastic materials to manufacture. An emerging chamber secures when the brush is connected to the dispenser the transport of the dentifrice, the donor guarantees one through its choice of materials certain stability and, due to its reaction to pressure, the transport of dentifrices.  

Description of the device combination with all advantages

The following "one-hand operation and easy manufacture" of a combination of Toothbrush and toothpaste dispenser is the goal of registration. The advantage of this patent is in prophylactic and easy handling. The use of the combination device forces completely simply for the regular toothbrush change required by dentists.

Furthermore, the easy handling enables use for disabled people here especially for citizens who only have one hand or arm amputation able to use functional arm / hand.

Description: Toothpaste dispensers and toothbrushes are combined in one added. By pressing the dispenser container, the tooth gel is applied directly to the integrated one Headed toothbrush head. The cleaning process can be started immediately without further delay begin. After the dispenser container has been emptied, the complete combination device is replaced green dot fed. Different colors can also "Confusion" can be avoided.

Advantage over previous combinations: "Two-hand operation" is no longer necessary! It is through a simply press on the combination device replaced.

Description of numbering in drawing 1:
Drawing 1: Brush body and head in sectional drawing ( 1 , 2 ) or side view of the combination
Drawing 2: from the left, view of the rubber membrane in the dispenser container (similar: diagonally cut baby nipples) with a rim as a sealing function 1
The rest position of the membrane ventilation hole or outlet channel are free 2
When pressure is applied to the dispenser, the membrane bulges into the connector. The ventilation hole is closed. Gel is pressed into the outlet channel. 3
Alternative 2.1: Possibility of using a tip for complete production (1 part, no more screwing required) 4
to 1 The brush head gets an outlet channel which is placed between the bristles.

Pressure on the dispenser container turns the tooth gel through the channel into the office brush head is directed and hits between the bristles, the cleaning process can begin.

to 2 The brush body is now additionally pulled through with a channel, this ensures that the tooth gel is transported to the brush head. (see drawing 3). The connector is integrated in the toothbrush part and is connected by an internal thread ( 6 ) to the dispenser container which has an external thread ( 6 ).

When the dispenser container ( 5 ) is pressed, the rubber insert in the dispenser container changes its shape (see drawing 2), it bulges outwards and the tooth gel enters the channel ( 1 ) and is guided to the brush head. At the same time, the rubber insert closes the ventilation hole. When the dispenser container is relieved, the soft rubber returns to its old shape and prevents the tooth gel from flowing back (ventilation hole free). The chamber created here by the screw connection and the use of soft rubber ( 5.1 ) cut 3 or 4 times in the middle around the gel transport and to secure the closing / opening of the ventilation duct and the connection with the planned dispenser body only enables progress to be made compared to previous products; complicated manufacturing techniques can be dispensed with entirely.

Alternatively (see 2.1), the use of a simple perforated tip on the Gel container which finds a corresponding connection in the brush body.

to 4 The use of a level indicator ( 4 ) should help the user to take care of replacement in good time. In any case, it must also be placed between the corresponding company and advertising logos.

to 5 The dispenser container is characterized by the use of a special material.

A plastic type similar to that of the tooth gel dispenser must be used as the material. It has a special basic strength that is essential for the cleaning process and can nevertheless take over the function of forwarding the tooth gel by pressure. The shape of the container can be both round and oval. An oval form of use is more beneficial. The size of the container is variable and can therefore also be adapted to children's hands. Here, a calculation must first be made to make the useful life interesting for all parties involved (price / performance). Since the use of probably two types of plastic is given, the dispenser container ( 5 ) and the brush body ( 4 ) must be produced separately. However, sales always take place in a completely screwed state. If a plastic grade meets both requirements, it is also possible to produce the combination in one operation using the alternative ( 2.1 ). The dispenser ( 5 ) is filled from above at the connection piece ( 6 ), then insert the membrane ( 5.1 ), screwing onto the brush head. When selling, make sure that hygienic packaging is placed over the brush part. Suggestion 1 = lid like deo's or 2 = foil packaging as before. The guidelines for the green dot must also be observed here.

Claims (3)

Generic term one-hand combination of toothbrush and dispenser container. The current state of the art is the combination of toothbrushes in various ways and connect toothpaste dispensers. In the process, functioning ones always emerged Units, but all previous ones are characterized by complicated techniques in the dispenser container (expensive manufacture) or by still indispensable "two-hand operation" from technical Solutions like the example of the exchangeable cartridge (Pat. No. 9017551) almost bring that One-hand operation (cartridge change two-hand operation) can, however, due to their concept tion (material savings and totally changed manufacturing processes) not in the interest of consumers and be industry. But the goal can only be to guarantee a simple manufacture of sales increase and the tooth required by dentists but neglected in the population guarantee brush replacement. The new combination is characterized in that the current connection chamber and the use of special material and shape of the dispenser container guarantee one-handed operation or simple and little changed production. The claim results from the connecting chamber ( 6 ) between the brush and the dispenser container and the material selection of the dispenser container ( 5 ). This new combination enables simple manufacture and secure "one-hand operation". The use of soft rubber ( 5.1 ) in the connection chamber enables the opening or closing of the indispensable ventilation duct. (Drawing 2 point 2 ventilation duct free at rest, point 3 when pressure is exerted on the dispenser container, rubber deforms in the direction of the chamber and closes the ventilation duct, the tooth gel can flow unhindered into the outlet duct Backflow of the gel is prevented;) The special material used for the dispenser container ( 5 ) enables the opening and closing of the tooth gel channel. In order to obtain a reliable function, the use of tooth gel (better fluidity) is preferable to that of a toothpaste. The use of a viewing strip ( 4 ) for checking the remaining filling in the dispenser container ( 5 ) is intended to guarantee the user of the information about changing the combination. The viewing strip ( 4 ) is not necessary when using glass-clear material for the dispenser container ( 5 ) because the available space can be used as advertising (see standard dental gel dispensers). In order to guarantee use in multi-person households, multicolored production must be guaranteed. Thanks to its preferably oval shape (but round is also possible), the dispenser container ensures optimal usability, especially when it comes to teaching young children how to brush their teeth.
The use of a special soft rubber in a newly designed connection chamber with ventilation duct guarantees easy handling (see drawing 2). The use of tooth gel ensures smooth transport to the brush head. (but toothpaste can also be used). The expansion chamber with ventilation hole is produced with the toothbrush part, the counterpart is the dispenser container with the soft rubber used ( 5.1 ). Alternatively, the soft rubber can be integrated into the brush. In any case, it must be ensured that after the screw connection (other connections such as plugging or welding are also conceivable), a chamber is created in which the soft rubber can move and thus fulfill its function. Finally, the dispenser container should also be mentioned, it is characterized by the fact that the material used has a certain strength (essential for the cleaning process) but can still perform its function as a dispenser when pressure is applied (see e.g. commercially available gel dispensers). The shape of the dispenser container can be designed in a variety of ways. The usual trade would be oval or round, but all polygons are also conceivable. If transparent material is used, a level indicator ( 4 ) can be dispensed with, opaque material requires the use of the indicator. Alternatively, the use of one in the connection chamber (drawing 2 Pt. 4) is also conceivable. Here the complete combination can be produced in one piece. The filling and closing of the gel container then takes place on the bottom of the dispenser container.
