  • thermoplastic resin material which comprises the container 11 is although it does not specifically limit, It is preferable that it is a hard material which has predetermined intensity

  • the thickness of the container 11 is 0.1 mm or more and 0.8 mm or less. Thereby, it can manufacture easily by extrusion molding. It is very difficult to mass produce this thickness by injection molding. Since it is manufactured by extrusion molding, it can be thinned, so that there is an advantage that material can be saved and productivity is high. However, if the thickness of the container is less than 0.1 mm, it is difficult to maintain the cylindrical shape, and there is a possibility of deformation when the dental viscous material is filled. On the other hand, if it exceeds 0.8 mm, the amount of material used increases and the productivity also decreases.

  • the dental viscous material 15 is a highly viscous material.
  • the specific viscosity is that having a consistency of 20 mm to 45 mm. If the consistency is less than 20 mm, the material is too hard to be suitable for treatment in the first place. On the other hand, if the consistency exceeds 45 mm, the viscosity is too low to leak out of the dental viscous material package, or it becomes difficult to scrape with a dental tool such as a spatula.
  • the consistency is 20 mm or more and 25 mm or less.

  • the dental viscous material package 10 as described above can be manufactured, for example, as follows. First, a cylindrical body that becomes the container 11 and is open at both ends thereof is manufactured by extrusion molding. Then, as shown in FIG. 4A, the material of the container 11 is heated and deformed into the groove 31 of the mold 30 provided with the end portion of the container 11 and the bottom of which has a semicircular groove 31. Push the end of the container 11 while possible. Thus, the projecting portion 12 is formed as shown in FIG. 4B by deforming the end portion so as to be guided and wound along the groove. According to this, a protrusion part can be easily formed, without requiring an additional material.
  • the dental viscous material 15 is filled into the inside of the cylindrical body from the opening at one end of both ends that are open. According to such a manufacturing method, the dental viscous material 15 can be filled inside the container 11 without air bubbles being mixed into the dental viscous material. Then, the inner stopper 16 is inserted from the opening of the container 11 on the side where the protruding portion 12 is formed.
