[0003] According to WG2009 / 113843A1 and WG2016 / 154060A1, dispensing devices with a vibration unit for dispensing pastes are known from the state of the art.

[0004] There is therefore a need to provide a dispensing device that opens up further application possibilities in the dental field, is easier to use, and increases user acceptance. Furthermore, there is a need for dispensing devices that allow users to concentrate on the application and / or modeling of a composition and provide force support for dispensing the composition. Furthermore, there is a need to be able to apply highly filled and thus highly viscous composites from a dispensing device; this has not been possible to date due to the high viscosity.

[0008] The invention also relates to an electronic dental dispensing device, in particular for the application of a dental and / or pharmaceutical composition, comprising a housing with a handle part with a connection geometry in the front housing area for receiving an application capsule with an outlet, in particular comprising an application capsule with a composition, in particular comprising a dental and / or pharmaceutical composition, or for receiving an adapter for receiving an application capsule with an outlet, in particular comprising a composition, with a reading unit for contactless data exchange via electromagnetic induction, and optionally with a radiation source, which is particularly suitable for the polymerization and / or curing of the dental and / or pharmaceutical composition, with an electronic vibration unit, in particular in the front housing area,which connects to the connection geometry inside the housing or receives it, preferably the vibration unit is coupled to a vibration damper which decouples the vibration unit from the housing, and to a manual or electronic squeezing device in the housing for squeezing the composition out of the outlet of the application capsule, and optionally to an electrical heat source, and optionally to a data transmission module, in particular a radio module, and to a rechargeable battery and at least one control unit and optionally to a display and optionally to an operating unit, and to a charging and / or data connection.

[0009] In a particularly preferred alternative, the dispensing device has a reading unit for contactless data exchange via electromagnetic induction.

This reading unit can preferably be an RFID reading unit, in particular an NFC reading unit. It is further preferred if the reading unit, in particular a reading unit with an antenna, receives or recognizes data for contactless data exchange via electronic induction and transmits this data to the control unit, in particular by means of an electrical connection. The reading unit particularly preferably comprises at least one antenna as at least one receiver or at least one receiving coil and / or transmitter or at least one transmitting coil.Furthermore, it is preferred if the reading unit transmits a defined carrier signal or several defined carrier signals for contactless data exchange.

Furthermore, it is preferred if the data transmission module of the dispensing device comprises, as a transmitting and / or receiving unit, an RFID transmitting and / or receiving unit and / or NFC transmitting and / or receiving unit (NFC: Near Field Communication), which particularly features two-way communication, preferably using one of the two methods: card emulation and / or peer-to-peer (P2).

[0011] Using NFC, data can be exchanged with smartphones or other NFC-enabled devices, especially close to each other, preferably within 10 cm. NFC uses RFID technology.

[0012] The RFID reader operates contactlessly due to the magnetic or electromagnetic coupling between the RFID transponder and the RFID reader.

The selected range of the delivery device can be adjusted by setting the RFID frequencies of the RFID reader and the RFID transponder, ranging from 1 cm to 10 m; 1 cm to 30 cm is preferred.

Data transmission between the transponder and the reading and / or receiving unit or reading and / or receiving device of the system can be achieved through inductive or capacitive coupling. This ensures a high level of data transmission security.

An Object Name Service (ONS) assigns an internet address in the form of a URL to the EPC serial number, which refers to an object description provided by the manufacturer in PML format. This allows information about tagged products and / or application capsules, in particular application capsules with composition, to be retrieved online at any time. The EPC was developed by the US-based organization EPCglobal. The EPC is compatible with the international article numbering system (EAN).

[0019] It may be preferred if the dispensing device has a reading unit and / or a data transmission module with an EPC standard, the RFID transponder and / or NCF transponder have the EPC standard, in particular the application capsule, the application device, preferably the control unit, the lookup table and / or the aforementioned components, etc. Furthermore, it is preferred if the EPC standard is equipped with an EPC Gen 2 interface. It is further preferred if the header of the product code, in particular the EPC header, always comprises at least 8 bits or from 8 to 256 bits.

The return position can be fixed by means of a locking mechanism of the plunger and / or the shaft.The pressing or moving of the inner plunger into the plunger allows the composition to expand into the released cavity within the plunger, thus preventing any overflow of the composition from the outlet of the application capsule. The reset position serves to prevent any overflow of the composition from the application capsule after squeezing.

[0055] The respective starting or squeezing position can depend on the selected application capsule and / or the fill level of the application capsule.
