Description

Description

The invention relates to transport and dosing bodies for dental filling materials and other dental materials. Various design principles have been specified for such bodies, which mostly resemble syringes or cannulas. Mention should be made, for example, of EPA 0 224 637 (Mühlbauer), DE OS 1 904 963 (Moschee), USP 4,189,065 (ESPE) or also EPA 0 220 551, G 85 805.5, G 85 28 512.9, and last but not least G 88 05 104.8 (all Mühlbauer).

However, all known dosing and transport bodies have in common that the color of the filling material contained inside the body - which plays a major role in dental materials - cannot be seen from the outside. This is because most filling materials for dental purposes harden in a short time when exposed to light. If a viewing hole were to be made inside the body, the color would be visible, but the filling material itself would harden quickly and thus become unusable. So, according to the current state of the art, the coloring is printed on the outside of the body according to a numerically or alphanumerically agreed identifier. As an accessory for the filler bodies, extensive "color rings" are sometimes provided to the user, based on which the color of the filler to be used is first determined by comparing it with the color of the tooth, after which the corresponding filler is selected and taken out of the transport container.

The disadvantage of this approach, however, is that the coloring shown on the so-called color ring and the fillers contained in the transport and dosing body only match to a limited extent.

This is particularly true for those color rings whose color pattern is not made from the actual filler, but from a filler-like plastic of a different chemical origin. But even with those color rings that are filled with the original filler, sometimes even in the practice, color deviations from the filler in the respective transport body occur over time. This is because the extremely complex production of the dental filler and its coloring, despite high precision, results in an unmistakable color deviation in fillers of "one color".

According to the invention, the problem is solved by attaching a device to the outside of the dosing and transport container that is suitable for holding the original filler. It is possible to fill the device at the manufacturer's site. On the other hand, the device can also be filled in the dentist's office.

It is a great advantage for color determination if the actual filling material and the sample introduced into the provision belong to one and the same batch.

As a variation of the solution according to the invention, it is also possible to anchor a pattern of the filler, preferably in an undercut notch, and to use the filler itself (as shown in Fig. 3 as No. 10) as a {functional) component of the device.

For example, parts of the flask or the lid, or even the container itself, can serve as color samples.

For the functioning of the solution according to the invention, it is therefore irrelevant whether the container is a syringe-like body, a compule or even a can. The only important thing is the presence of a provision for attaching a color sample of the container inside.

The attached drawings (Fig. 1 to 3) explain the transport and dosing body according to the invention in more detail:

shows the filler body with the main container part (1), the piston (2a, 2b), which in this case is drawn as consisting of two parts (2a) and (2b), and the front cover (3), which covers the outlet opening (5).

The devices according to the invention were shown in this Fig.

shown as examples on the lid (4a), on the container body (4d) and twice on the piston (4b, 4c).

It does not matter whether the piston can be pushed into the container (1) by simply pushing it in or whether the piston is mounted so that it can rotate against the container (1).

For practical use, it is sufficient if one of the aforementioned recesses (4a-d) is attached to the transport body.

shows an example of a compule-like design of the container. The piston (7) protrudes above the container itself only in the area of the provision (4e). In this case, the provision is designed to be breakable or tearable. Provisions attached elsewhere can also be tearable or breakable.

On the other hand, in this case too, as shown, the provision (4f) can be attached to the container itself or (as not shown) to the lid (8).

shows a simple device with a container (1) and a piston (H), whereby the handle part (10) of the piston was made from the color sample. Alternatively, the color sample can also be attached to the lid or the container part in a similar way.

Claims (9)

Device for dosing and transporting dental masses with external recess provision. Claims 1. Device for transporting and dosing dental materials, consisting of a container containing the filling material, an outlet opening for the filling material from this container and a piston for squeezing the filling material out of the outlet opening, characterized, that on the outside of one of the components of the device a recess is provided for receiving filling material. 2. Device according to claim 1,
characterized in that the component containing the provision consists entirely or partly of a transparent or opaque-transparent material. 3. Device according to claim 1 or 2, characterized in that the sparing providence is open from two or more sides. 4. Device according to one of claims 1 to 3, characterized in that the recessed area contains undercuts which are designed in such a way that filling materials which are plastically introduced into the area can no longer fall out of the area after they have hardened. 5. Device according to one of the preceding claims, characterized in that the recessed provision is filled with the filler of the batch contained in the dosing and transport body or contains a filler batch of identical color. 6. Device according to one of the preceding claims, characterized in that the filling of the container can take place during and in addition to the actual filling of the container during production in one or more successive production processes. 7. Device on transport containers, in particular according to claim 4, characterized in that the curing of the filling material in the device takes place by means of light activation. 8. Device according to one of the preceding claims, characterized in that the recessed and fillable provision for the dosing and transport body is attached in a tear-off or breakable manner. 9. Device for transporting and dosing dental materials, characterized in that a sample of the filling material contained in the container is a functional or structural component of the device.
