Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention uses a tooth restoration material composed of two components, powder and liquid, used for filling, bonding, lining, filling and other tooth restoration. The present invention relates to a capsule for tooth restoration material used in.

[Conventional technology]

Tooth restorations are generally filled with tooth restoration materials. As such a tooth restoration material, a two-component material which is easily reacted by mixing is usually used. This binary material often consists of a combination of powder and liquid,
Each is packaged in a glass bottle or a plastic bottle and supplied to the market. Since such a two-component material undergoes a rapid hardening reaction after mixing, it is necessary to fill the dental cavity as quickly as possible before hardening.

Since the operation of weighing the bottled material immediately before filling and mixing it with a spatula or the like is complicated and time-consuming, in recent years capsules in which a certain amount of powder and liquid are stored in an isolated state have become commercially available, There is no need, and mixing and kneading after combining the two components can be completed in a few seconds by applying mechanical vibration to the capsule.

[Problems to be solved by the invention]

However, even if a capsule in which the tooth restoration material as described above is measured in advance by a predetermined amount and stored,
It takes time to fill the tooth cavity with the mixed contents thus extracted from the capsule to another container once, and especially when the temperature is high, hardening of the mixed and kneaded tooth restoration material occurs. Since the reaction becomes faster, there is a problem that the curing progresses considerably at the time of filling and often fails.

[Means for solving problems]

Therefore, as a result of various studies to solve the above problems, the present inventors knead the tooth restoration material in the capsule and immediately put it on to inject the capsule contents into the dental cavity. A syringe for tooth restoration material for pushing out capsule contents that can be carried out more quickly than the nozzle provided at the tip of the capsule and does not disturb the gaze of the restoration position in the narrow oral cavity and does not give a feeling of pressure to the patient. Akira Akira first
Proposed in No. 60-201319.

With the development of such a tooth restoration material syringe, it has become possible to quickly fill the tooth restoration part with the mixed and kneaded tooth restoration material in the tooth restoration material capsule. Among the tooth restorative materials consisting of powder and liquid that are stored in a separated state in the above, at which position of the capsule the pack in which the liquid of the tooth restorative material is stored is previously placed, How to pack the liquid of the tooth restoration material into the powder of the tooth restoration material so that the liquid can be supplied to the tooth restoration portion becomes a problem.

That is, for example, in the case of a capsule composed of a dental preparation mixing container having a structure as disclosed in Japanese Utility Model Publication No. 55-46625, a pressure burst pack containing a liquid of a tooth restoration material is used as a cylinder. Since it is located at the side of the cylinder, a complicated shape that a mounting part of the clip for holding the pack must be provided on the side of the cylinder is required, and the presence of this clip unnecessarily increases the diameter of the capsule. There was a drawback.

Therefore, the inventors of the present invention have placed a pressure bursting pack, in which the liquid of the tooth restoration material is stored inside and one of which is made of a weak material, inside the plunger at the rear end of the cylinder. The present invention has been completed by finding out that it is not necessary to provide a clip mounting portion on the side portion of the cylinder as in No. 55-46625.

That is, according to the present invention, a nozzle is provided at the tip, a predetermined amount of powder of tooth restoration material is stored inside, and a pushing plunger is fitted at the rear end of the cylinder. A through hole is formed in the through hole, and a rear portion continuous to the through hole forms a hollow cylindrical portion, and a hollow tooth portion of the hollow cylindrical portion of the pushing plunger has a tooth restoration material inside thereof. A pressure rupture pack containing a liquid and having a weak through hole side is stored, and the pressure rupture pack is pressed and ruptured on the side opposite to the through hole of the hollow cylindrical portion of the extrusion plunger. The present invention provides a capsule for tooth restorative material, wherein a pressing body for pressing is held.
