DE19534912C1 - Combined toothpaste dispenser and toothbrush - Google Patents

Abstract

The dispenser and toothbrush combination have a hollow tube (3.1) for holding the toothpaste, to which the handle (2.1) of the toothbrush is pivoted at one end, the opposite end of the tube having a dispensing head (1.3) for applying the toothpaste to the interchangeable toothbrush head (1.2). The toothpaste is contained within a flexible foil sleeve (1.1) and is dispensed via a pusher (1.7), cooperating with a toothed rack along the inside of the hollow tube and displaced along the rack each time the toothbrush is pivoted relative to the tube.

Description

The invention relates to a donor toothbrush according to the preamble of Claim 1.

Such a donor toothbrush is known from DE-GM 71 18 432. The hollow handle serves as a refillable toothpaste container. For the Dosage is a squeezing device that the toothpaste too promotes an opening into which the brush head swivels on the handle stored toothbrush can immerse. A regular exchange Various wear or functional parts are not provided.

The US 53 82 107 A shows a similar donor toothbrush, in which the Brush head is interchangeable.

DE 42 21 438 C2 and DE 34 23 400 C2 show Dispenser toothbrushes, in which a replaceable toothpaste container in the Handle of the toothbrush is emptied in a metered manner using an extrusion device becomes. A squeeze slide is based on one sawtooth-shaped bar from the handle. DE 34 23 400 C2 shows the possibility of the squeezing process by turning a lever to reach. The toothpaste is dosed in both cases a channel in the toothbrush handle to the bristles. This is one There is a risk of incrustation.

Other toothpaste dispensing mechanisms are in many variations known. However, their structure is complicated and accordingly expensive, while being cumbersome or inaccurate regarding handling and function.

For example, it is difficult to make the tube in the form of a cartridge train, because a connection to the dispensing mechanism a detachable Management is required.

Elaborate valve mechanisms are required in order to to achieve satisfactory dosing of the paste.

Closing the tube or cartridge creates great problems due to the depositing and crusting of the toothpaste on her Outlet opening. Toothbrushes and interchangeable brush heads are subject to strong mechanical stress and should therefore be replaced after a period of about 6-8 weeks. This usually happens however at your own discretion, so that a timely renewal is not guaranteed by a mandatory cycle.  

Furthermore, the storage of the toothbrush is in the unused period completely inadequate from a hygienic and practical point of view.

These conditions plus the relatively large plastic or Aluminum waste due to the robust construction of the toothpaste tubes or disposable toothbrushes require a redesign of the previous known dentifrices.

The object of the invention is a generic To improve donor toothbrush so that a simple regular Exchange of wear and functional parts as well as a simple one Operation of the dispensing mechanism is possible.

This task is characterized by the characterizing features of the claim 1 solved.

The invention makes a meaningful division of the three components Toothbrush, toothpaste container and dispenser reached. Of the Disposable depot hose and the interchangeable brush head are used as or wear parts easy to replace, while toothbrush handle and Dispensers can be used permanently.

The donor is a basic body that contains the donation mechanism, with the interchangeable disposable depot hose and the lever attached brush handle together forms the donor toothbrush.

An advantageous development of the donor toothbrush is that Interchangeable brush heads of electric toothbrushes instead of commercially available interchangeable brush heads are used for manual toothbrushes will.

An embodiment of the donor toothbrush is in the drawing shown schematically.

Fig. 5 is a cross-sectional view of the foot end (3.1 b) of the base body (3.1)

An approximately 22 cm long plastic tube with a diameter of approximately 2.5 cm serves as the base body ( 3.1 ).

At its head end ( 3.1 a) there is a rectangular recess ( 3.2 ) of 1.5 × 3.5 cm, which is open towards the top, and at the foot end ( 3.2 a) has a spring bolt ( 3.3 ) embedded in the wall in the center. In its extension, a sawtooth ( 3.4 ) with a width of 3 mm runs into the wall and runs to the foot of the base body ( 3.1 b).

A deflection mechanism ( 3.5 ) is attached there, the pivot point ( 3.5 a) of which lies outside the wall of the base body ( 3.1 ).

The smaller lever arm ( 3.6 ) extends into the base body ( 3.1 ), has a length of approx. 0.5 cm and is designed as a hook ( 3.6 ). The counterpart is a sleeve ( 3.7 ) attached to the deflection mechanism ( 3.5 ), into which the brush handle ( 2.1 ), the head end of which can be replaced by an interchangeable brush ( 1.2 ), is inserted as an extended lever arm.

The heart of the donor toothbrush is the replaceable disposable depot tube ( 1.1 ) for toothpaste and brush head ( 1.2 ).

Its cap is designed as a rigid funnel-shaped quiver ( 1.3 ), the smaller base ( 1.3 a), which represents the outlet opening of the toothpaste, is connected at right angles to the film tube ( 1.5 ) via a flange ( 1.4 ).

The reinforcement ( 1.6 ) incorporated into the hose back and designed for tensile strength is guided with the film ( 1.5 ) which is eccentrically combined at the end through a squeeze slide ( 1.7 ) and provided with a mandrel ( 1.8 ).

The interchangeable brush head ( 1.2 ) is placed inside the funnel-shaped quiver ( 1.3 ) so that the bristles ( 1.2 a) are bundled in the smaller opening ( 1.3 a). The brush base ( 1.2 b) is conically congruent with the large opening ( 1.3 b) of the funnel.

As a result, the quiver ( 1.3 ) is sealed to the outside and the brush can be immersed in the pressed-out toothpaste.

The donor toothbrush is used as follows:
First, the bulging depot hose ( 1.1 ) is inserted into the dispenser ( 3 ) from above. It is necessary to bend it slightly in front of the squeeze slide ( 1.7 ) to prevent it from touching the rack ( 3.4 ).

The quiver ( 1.3 ) in which the interchangeable brush head ( 1.2 ) secured with an adhesive strip or similar slides into the cutout ( 3.2 ) of the base body ( 3.1 ) described above.

In order to hang the depot hose ( 1.1 ) by means of the mandrel ( 1.8 ) on the hook ( 3.6 ) of the deflection mechanism ( 3.5 ), the quiver ( 1.3 ) must be pressed against the spring bolt ( 3.3 ) with moderate pressure.

Since the deflection mechanism ( 3.5 ) borders on its swivel range ( 3.5 b), this has the consequence that the depot hose ( 1.1 ) is clamped tightly over its entire length in the dispenser ( 3 ) and the squeeze slide ( 1.7 ) under relative pressure in the teeth ( 3.4 ) of the base body ( 3.1 ) engages.

If you now swivel the brush handle ( 2.1 ) attached to the deflection mechanism ( 3.5 ) towards the head end ( 3.1 a), the entire depot hose ( 1.1 ) is pulled one more against the force of the spring bolt ( 3.3 ) into the base body ( 3.1 ). The squeeze slide ( 1.7 ) must maintain its position as a result of the toothed rack ( 3.4 ), and the film tube ( 1.5 ) slides through it by approx. 2-3 mm.

At this point in time, no toothpaste is being pumped into the interior of the quiver, as the funnel-shaped squeeze slide ( 1.7 ) is only now in contact with the bulging depot tube ( 1.1 ).

The brush handle ( 2.1 ) is now parallel to the dispenser ( 3 ) and can hold the replaceable head ( 1.2 ) permanently. A snap lock ( 3.8 ) located on the base body ( 3.1 ) prevents the toothbrush ( 2 ) from opening unintentionally.

If the lock ( 3.8 ) is unlocked, both the toothbrush ( 2 ) and the depot hose ( 1.1 ) are set in motion by the force of the spring bolt ( 3.3 ). The funnel-shaped squeeze slide ( 1.7 ) is so narrow at its outlet ( 1.7 a) that it moves with the bundled film tube over the rack ( 3.4 ).

When the donor toothbrush is closed again, the paste is dosed into the interior of the quiver ( 1.3 a). The bristles ( 1.2 ) are immersed in it and absorb the toothpaste in their front part ( 1.2 a). When opened, the toothbrush ( 2 ) can be easily removed from the sleeve ( 3.7 ) and its actual purpose and shape can be used.

Modified attachments of electric toothbrushes can also be used in conjunction with the extended sleeve ( 3.7 ).
