Description

  The present invention is intended for use in filling, bonding, lining, and other applications for dental restoration in the field of dental treatment, as soon as the two-component dental restoration material is mixed and kneaded, and immediately after the patient is to be restored. The present invention relates to a capsule for a tooth restoration material that can be administered.

  In general, tooth restoration materials are used for restoration of teeth. As the tooth restoration material, a material composed of a powder component that reacts by mixing and kneading and a liquid component or liquid components is generally used. . Conventionally, these two-component tooth restorative materials have been used by mixing and kneading each component as appropriate. However, in recent years, a certain amount of each component has been weighed in advance for the purpose of omitting the weighing operation of each component and the operation of storing the tooth restoration material after mixing and kneading it into the syringe for administration to the site to be restored. Each of these is stored in an isolated state, and when desired, the isolated state is released and mechanically mixed and kneaded with a mixer or the like, and this mixed kneaded material is restored to a tooth cavity or the like through a nozzle. Tooth restoration capsules have been developed that are extruded and administered directly to the teeth.

  As such a capsule for a tooth restoration material, for example, a first opening formed in a cylindrical shape having a mixing compartment in which a powder component is accommodated and forming an outlet hole of the mixed kneaded material on the center axis of the tip portion thereof. And a second opening forming portion for forming a liquid component outlet hole on the central axis of the tip portion of the capsule body having a liquid component storage chamber in which the liquid component is stored. When the capsule body is fitted to the cylindrical part forming the mixing compartment of the capsule body and the second opening forming part is pushed through the outer surface in the vicinity of the rear end part to form an outlet hole for the liquid component A liquid cup provided with a convex stopper of a size that does not obstruct the entry into the capsule body when a large force is applied but is not easily slid into the second opening, and the second opening of the liquid cup form A plunger having a rod-like projection for pushing through the portion and the first opening forming portion of the capsule body, and being fitted to a cylindrical portion in the liquid cup, and a rear end portion at the tip portion of the capsule body There is a capsule for a tooth restoration material (see, for example, Patent Document 1) which has a corresponding shape and includes a nozzle connected to the tip of the capsule body.

  In order to mix and knead the two components housed individually using such a capsule for tooth restoration material, first, the plunger is slid to the tip side, and the second opening forming portion of the liquid cup is formed by the rod-shaped protrusion of the plunger. A capsule holding chamber for holding, for example, a capsule for a tooth restoration material and the capsule holding chamber after the liquid component stored in the liquid cup is allowed to flow into the mixing compartment in which the powder component of the capsule body is stored. A capsule kneading device for capsules for tooth restoration comprising a capsule holding chamber rotating means for circularly moving the capsule holding chamber itself in a state in which the longitudinal direction of the chamber is maintained in a constant direction, and a driving means for driving the capsule holding chamber rotating means (For example, refer to Patent Document 2.) Or, the powder component and the liquid component of the tooth restoration material are shaken and mixed and kneaded in the mixing compartment of the capsule for tooth restoration material. Therefore, a tooth in which two components are present in the mixing compartment of a device such as a device for kneading a capsule for a tooth restoration material (see, for example, Patent Document 3) having a capsule holding chamber for holding a capsule for a tooth restoration material The restoration material capsule is mounted, and thereafter, both components in the mixing compartment of the dental restoration material capsule are mixed and kneaded by rotating or shaking the dental restoration material capsule itself with such a device.

  However, in such a capsule for tooth restoration material, although the two components constituting the tooth restoration material can be mixed and kneaded in the mixing compartment of the capsule body of the capsule for tooth restoration material, a mixture can be easily obtained. When mixing and kneading the two components constituting the tooth restoration material in the mixing compartment of the capsule body of the capsule for tooth restoration material, the capsule for tooth restoration material itself is used by using a kneading device for capsules for tooth restoration material. By holding and rotating or shaking, the two components constituting the tooth restorative material collide with the inner wall of the mixing compartment of the capsule body and / or move indirectly along the inner wall, thereby indirectly in the mixing compartment of the capsule body. Since the two components are mixed and kneaded, there is not only a disadvantage that the mixing and kneading efficiency is bad, but also the viscosity of the mixture to be kneaded is mixed. Is higher, in the action of such indirect mixing and kneading, were a drawback that the efficiency of the mixing and kneading will further deteriorate.

  Further, in such a capsule for a tooth restoration material, as described above, the two components constituting the tooth restoration material collide with the inner wall of the mixing compartment of the capsule body and / or move along the inner wall to move the capsule body. Since the two components constituting the tooth restoration material are mixed and kneaded indirectly in the mixing compartment, the tooth restoration material is constituted in the mixing compartment of the capsule body of the tooth restoration material capsule. Space is required for the components to impact and / or move along the inner wall of the mixing compartment. For this reason, the capsule body has a drawback that it must be a capsule for a dental restoration material in which a mixing compartment having a large volume compared with the volume necessary for simply storing these two components is contained as a mixing compartment of the capsule body. In addition to improving the efficiency of mixing and mixing the capsules for tooth restoration materials, when the two components constituting the tooth restoration material collide with the inner walls in the mixing compartment having a certain space, the inner walls thereof Because it is necessary to increase the amount of movement when moving along the tooth, the tooth restoration in which a large volume mixing compartment having a larger space is formed in order to mix and knead these two components efficiently and uniformly There was also a drawback that it had to be a capsule for the material.

  Further, the rotational force transmission engaging portion is formed of a plurality of driving engagement portions that are concave and / or convex on the rear end side and to which rotational force is applied, or the rotational force transmission engaging portion is a capsule. If the cross section provided at a position that coincides with the central axis of the mixing compartment of the main body is concave or convex other than circular, the mode in which the rotational force transmitting engagement site is provided at the rear end of the plunger, Even if it is the thing which consists of a plate-like thing fixed to the rear end side of the penetration stirring rod object, it is not only preferable that the plunger can be reliably rotated, and the rotational force transmitting engagement site is In the case of an aspect composed of a plurality of driving engaging portions, for example, an engaging member provided with a concave shape and / or a convex shape that can be engaged with the plurality of driving engaging portions is mounted on the shaft of the driving means. , Transmit the rotational force to the concave and / or convex shape of the engaging member Since it is inserted and engaged with a plurality of driving engaging portions at the joint portion and rotated, the rotational force transmitting engaging portion can be moved even if the engaging force between the engaging member and the rotational force transmitting engaging portion is relatively weak. Since it can be rotated, it is preferable that the drive means can be easily attached to and detached from the rotational force transmission engaging portion, and a transverse section provided at a position where the rotational force transmission engaging portion coincides with the central axis is provided. In the case of a concave or convex shape other than a circle, for example, the shaft of the driving means is directly fitted into the concave shape of this rotational force transmission engaging portion, or the convex shape of this rotational force transmission engaging portion is directly connected to the shaft of the driving means. Since the structure of the rotational force transmitting engagement portion can be simplified, it is preferable to select it appropriately according to the situation.

  Further, a through hole is formed at a position coinciding with the central axis of the mixing compartment of the capsule main body of the capsule body of the second pressing portion formed in a plate shape fixed to the rear end side of the through stirring rod body, and the second If the first pressing part of the plunger is located at the desired part from the through hole when viewed from the rear end side of the pressing part, and the first pressing part also serves as the rotational force transmission engaging part, the penetrating stirring rod body It is preferable that the second pressing portion of the plunger can be surely pressed, and the first pressing portion of the plunger can also have a function of applying a rotational force for rotating the plunger. In the mode having the plunger, the plunger is at a position away from the first pressing portion and the storage compartment and at a position away from the central axis of the mixing compartment of the capsule body to the circumferential side more than the maximum thickness of the rod-shaped protrusion. From the rear end to the front end A through hole for a stirring bar formed in parallel with the central axis of the mixing compartment of the capsule body in the shape of the same cross section is further drilled, and for the stirring bar of the plunger in the plate-like second pressing portion If the stirring-only rod body that has a slidable shape in the through-hole and is substantially the same length as the through-stirring rod body and is fitted in the plunger stirring rod through-hole is further fixed, Not only is it preferable that the mixing and kneading efficiency can be remarkably improved, but also the plunger has a storage compartment that has an opening opening for introduction at its tip and stores the second component. In comparison, it is simpler and lower in manufacturing cost to form a stirring rod through hole having the same cross section from the rear end to the front end. For example, one through stirring rod body and one A plate-like second pusher with a stirring rod When using a portion and a plunger having one storage compartment and one stirring rod through hole, a plate-like second pressing portion to which two penetration stirring rod bodies are fixed, Compared to a case where a plunger having two storage compartments is used, it is preferable that the production cost can be reduced while maintaining the high mixing and kneading efficiency.

  And in the aspect provided with the through-hole for stirring rods and the stirring-only rod body of the plunger, if the plunger has a plurality of through-holes for stirring rods, one or a plurality of through-holes may be used during mixing and kneading. Since the first component and the second component in the mixing compartment of the capsule body can be mixed and kneaded with the stirring rod body and the plurality of dedicated stirring rod bodies, the mixing and kneading efficiency can be further improved, which is preferable. In addition, if the storage compartment of the plunger and the through hole for the stirring rod are formed so that the distances from the respective central axis to the central axis of the plunger are different from each other, one or a plurality of through stirring rod bodies or 1 One or a plurality of stirring rods are rotated so as to revolve at different positions around the central axis of the plunger, which is preferable because the mixing and kneading efficiency can be remarkably improved. If the storage compartment of the ranger and the through hole for the stirrer are drilled at positions at equal angles to the central axis of the plunger when viewed from the rear end side of the plunger, mixing of the capsule body Since uniform mixing force can be applied to both components in the compartment, it is preferable that the mixing and kneading efficiency can be remarkably improved. Further, when the plunger is viewed from the rear end side of the plunger, the plunger If there is a through hole for a stirring bar that is drilled so as to be located in the vicinity of the outer peripheral edge of the capsule, a large stirring force can be applied to both components in the mixing compartment of the capsule body. It is preferable because the sum efficiency can be remarkably improved.

  In the drawings, reference numeral 1 denotes a cylindrical shape having a circular inner cross-section, and a discharge opening rupture portion 1a is formed on the tip side thereof, and a mixing compartment 1b in which a first component A is stored is formed. It is a capsule body, and a nozzle 5 (described later) for discharging the mixture C in the mixing compartment 1b is fixed or attached to the tip of the capsule body, and a plunger 2 (described later) is rotatable and slides from the rear end side. The first component A and the second component B are mixed and kneaded into a mixture C in the mixing compartment 1b formed on the tip end side of the plunger 2 inserted into the cylinder freely.

  The capsule body 1 has a transverse section as shown in FIGS. 3 and 9 because a plunger 2 to be described later, which is slidably inserted from the rear end side, is rotated around the central axis of the plunger 2 in the cylinder. The inner surface of the capsule body 1 needs to be circular, and the capsule body 1 is provided on the outer peripheral surface of the capsule body 1 as shown in FIGS. 1, 4 to 8, 10, 11, and 16 to 19 for a tooth restoration material. It is preferable that an engaging portion (for example, an engaging portion such as a groove formed on the rear end side of the outer peripheral surface of the capsule body 1) to be attached to the capsule kneading device or the extrusion device is formed. The engaging portion applies a rotational force to a rotational force transmission engaging portion 4 described later and rotates the penetrating stirring rod body 3 together with the plunger 2 described later, so that the capsule body 1 itself becomes the plunger 2 or the penetrating stirring rod. It is preferable that the capsule body 1 has a shape that can be locked against the rotational force applied to the rotational force transmission engaging portion 4 so as not to rotate together with the body 3.

  A discharge opening rupture portion 1a is formed on the distal end side of the capsule body 1, and this discharge opening rupture portion 1a is mixed with the first component A and the second component B in the mixing compartment 1b. When the mixture C obtained by kneading is discharged through a nozzle 5 described later, the mixture compartment 1b and the nozzle 5 communicate with each other by being broken by a rod-shaped protrusion 2a of a plunger 2 described later. As the discharge opening rupture portion 1a, for example, a linear portion surrounding the discharge opening rupture portion 1a as shown in FIG. 1, FIG. 4 to FIG. 8, FIG. 10, FIG. If the discharge opening rupture portion 1a is pushed down by a rod-like protrusion 2a of the plunger 2 to be described later, the other linear portion is left except for the thicker linear portion. Since it is broken, the thin linear part can be easily broken with a weak force, and Preferred discharge openings rupture portion 1a is able to prevent that mixed in the mixture C is completely detached from the capsule body 1.

  Fixed to the distal end of the capsule body 1 is a later-described nozzle 5 for directly administering the mixture C in the mixing compartment 1b discharged from the broken discharge opening rupture portion 1a to a portion to be repaired by the patient. Alternatively, the shape of the tip of the capsule body 1 is such that the nozzle 5 can be fixed or attached, and the mixture C discharged from the discharge opening breaking portion 1a does not leak to the outside. If it is formed in the shape which can be made to flow in into nozzle 5, it will not be limited in particular.

  2 has a cylindrical shape and is slidably fitted in the mixing compartment 1b so as to be rotatable in the capsule body 1 and to allow the mixture C in the mixing compartment 1b of the capsule body 1 to be pushed out. A rod-like protrusion 2a for pushing and breaking the discharge opening breaking portion 1a of the capsule body 1 is projected at a substantially central position of the distal end, and a first pressing portion 2b pressed toward the distal end is provided at the rear end. At the position away from the first pressing portion 2b and at the position away from the central axis of the mixing compartment 1b of the capsule body 1 to the circumferential side more than the maximum thickness of the rod-shaped protrusion 2a, the distal end side from the insertion port 2ca opened at the rear end A storage compartment 2c that is formed in parallel with the central axis of the mixing compartment 1b of the capsule body 1 and contains the second component B is formed in a shape that has the same cross-section up to the opening breaking portion 2cb for introduction. And the insertion slot 2ca at the rear end of the storage compartment 2c. When a through stirring rod body 3 to be described later inserted in the slide is slid to the tip side, the introduction opening breaking portion 2cb on the tip side of the storage compartment 2c is pushed and stored in the storage compartment 2c. The second component B is introduced into the mixing compartment 1b of the capsule body 1 in which the first component A is accommodated, and the penetrating stirrer 3 is further slid toward the tip side, thereby penetrating the stirrer 3 When the rotational force is applied to the rotational force transmitting engagement portion 4 to be described later with the distal end of the capsule body 1 in contact with the inner surface of the distal end of the mixing compartment 1b of the capsule body 1 or in the vicinity of the inner surface of the distal end of the capsule body 1, The first component A and the second component B in the mixing compartment 1b of the capsule body 1 are mixed and kneaded into a mixture C by being rotated together with the penetrating stirring rod 3 protruding from the front end side of the compartment 2c. Play a role.

  As shown in FIGS. 1, 3 to 8, 10, 11, and 16 to 19, the plunger 2 has a capsule body 1 in a mixing compartment 1b of the capsule body 1 in which the first component A is accommodated. It is rotatably slidable from the rear end side of the opening of the capsule body 1 and is slidably fitted so that the mixture C in the mixing compartment 1b of the capsule body 1 can be pushed out. When the first pressing portion 2b of the plunger 2 is pressed toward the distal end, the mixing compartment of the capsule body 1 is pushed by the rod-shaped protrusion 2a as shown in FIG. After the discharge opening break 1a of 1b is pushed through to open the front end side of the mixing compartment 1b into a nozzle 5 which will be described later, the mixture C in the mixing compartment 1b is pushed out by the front end surface of the plunger 2 and the nozzle 5 is discharged outwardly.

  The reason why the rod-like protrusion 2a of the plunger 2 is provided at the approximate center position of the tip of the plunger 2 is that the rod-like protrusion 2a is located at a position other than the center position of the tip of the plunger 2, for example, the tip side of the plunger 2 If it is projected from a position in the vicinity of the outer peripheral edge of the plunger 2 when viewed from above, a rotational force is applied to a rotational force transmitting engagement portion 4 to be described later, and the plunger 2 is rotated about its central axis. Later, the position where the rod-shaped protrusion 2a is provided is displaced from the initial position before the rotation to another position on the circumference around the central axis in the vicinity of the outer peripheral edge of the plunger 2. Even if the pressing part 2b is pressed to the tip side, a situation occurs in which the discharge opening breaking part 1a of the mixing compartment 1b of the capsule body 1 cannot be broken. With protrusion 2a A rod-like protrusion 2a is formed at the substantially central position of the tip of the plunger 2 so that the protruding position of the plunger 2 hardly changes even before and after the rotation of the plunger 2 so that the discharge opening breaking portion 1a can be surely pushed through. It is protruding.

  The plunger 2 has a first pressing portion 2b at its rear end, and the first pressing portion 2b of the plunger 2 pushes out the mixture C in the mixing compartment 1b of the capsule body 1 as shown in FIG. This is a portion that is pressed toward the tip when discharged outward through the nozzle 5, and the first pressing portion 2b is obstructed by a penetrating stirrer 3 and a rotational force transmission engaging portion 4 to be described later. Anything can be used as long as it can press the rear end of the plunger 2 toward the front end without being changed. The position will be different.

  Specifically, as the first pressing portion 2b of the plunger 2, for example, as shown in FIGS. 1, 2, 4, 4, 5, 10 and 16 to 18, a plate-like rotational force transmission mechanism described later is used. In the case where the press-through hole 4a penetrating from the rear end side to the front end side is provided in the joint portion 4, the first press portion 2b is located at a desired portion from the press-through hole 4a. Further, as shown in FIGS. 6, 7 and 19, the center of the mixing compartment 1b of the capsule body 1 of the plate-like second pressing portion 3a which is fixed to the rear end side of the penetration stirring rod 3 which will be described later is provided. In the case where the through hole 3e is formed at a position that coincides with the axis, the first pressing portion 2b is desired from the through hole 3e when viewed from the rear end side of the second pressing portion 3a. The first pressing part 2b of the plunger 2 is located at the part and also serves as a rotational force transmission engaging part 4 to be described later. Further, as shown in FIGS. 8 and 9, a rotational force transmission engaging portion 4 to be described later has a plate shape in which the cross section is formed smaller than the cross section of the plunger 2, and a through stirring rod body 3 to be described later. In the case where the rear end is fixed to the rear end side and the rear end forms the second pressing portion 3a of the penetrating stirring rod 3, the first pressing portion 2b is the rotational force transmitting engagement portion 4 When viewed from the rear end side, it is located between the peripheral wall of the rotational force transmission engaging portion 4 and the inner peripheral wall of the capsule body 1, and as shown in FIG. Is provided at the rear end of the plunger 2, the first pressing portion 2b is located at the rotational force transmitting engagement portion 4 itself and / or the rear end portion of the plunger 2 around it. In addition, as shown in FIG. A stopper portion 2d having a larger cross-section than the cross-section is formed, and a rotational force transmitting engagement portion 4 to be described later is formed so that its cross-section is smaller than the cross-section of the stopper portion 2d of the plunger 2. In the case of a mode in which the plate is formed and is fixed to the rear end side of the penetrating stirring bar 3 and the rear end forms the second pressing portion 3a of the penetrating stirring bar 3, this first pressing The portion 2b is located between the peripheral wall of the rotational force transmission engagement portion 4 and the outer peripheral wall of the stopper portion 2d of the plunger 2 when viewed from the rear end side of the rotational force transmission engagement portion 4.

  The plunger 2 is mixed with the capsule body 1 at a position away from the first pressing portion 2b as shown in FIGS. 1, 3, 4 to 8, 10, 11, and 16 to 19. A shape having the same cross-section from the insertion opening 2ca opening at the rear end to the opening opening breaking portion 2cb on the front end at a position separated from the central axis of the compartment 1b to the circumferential side more than the maximum thickness of the rod-shaped protrusion 2a A storage compartment 2c formed parallel to the central axis of the mixing compartment 1b of the capsule body 1 and containing the second component B is perforated. The storage compartment 2c contains the second component B. In this state, a penetration stirring rod 3 described later is slidably fitted into the distal end side through the insertion port 2ca at the rear end of the storage compartment 2c, so that the first inside of the storage compartment 2c as shown in FIG. The two components B are stored without leaking to the outside, and the penetration stirring bar 3 is pressed toward the tip side. As shown in FIG. 4, the mixing component chamber 1b of the capsule body 1 in which the first component A is stored becomes the second component B that is stored by being pushed through the opening opening breaking portion 2cb on the leading end side. The rotational force described later after being introduced into the inside and pressed until the tip of the penetrating stirring bar 3 comes into contact with the inner surface of the front end of the mixing compartment 1b of the capsule body 1 or enters the vicinity of the inner surface of the tip. When the plunger 2 is rotated in the mixing compartment 1b about its central axis by applying a rotational force to the transmission engagement portion 4, the penetrating stirring rod 3 protrudes from the tip of the plunger 2 Thus, it is rotated integrally with the plunger 2 so as to revolve around the central axis of the plunger 2 in the mixing compartment 1b.

  The storage compartment chamber 2c of the plunger 2 needs to be drilled at a position away from the first pressing portion 2b of the plunger 2. The penetration stirring rod 3 described later is inserted into the storage compartment chamber 2c. This is because the insertion port 2ca at the rear end of the storage compartment 2c cannot be pressed to the tip side. On the other hand, the storage compartment 2c of the plunger 2 is the center of the mixing compartment 1b of the capsule body 1. It is necessary to drill from the axis to the circumference side more than the maximum thickness of the rod-like protrusion 2a of the plunger 2 by pushing the penetrating stirring bar 3 (described later) inserted into the storage compartment 2c toward the tip side. Then, the opening breaking portion 2cb for introduction of the storage compartment 2c is pushed through to introduce the second component B into the mixing compartment 1b of the capsule body 1, and the tip thereof is on the inner surface of the tip of the mixing compartment 1b of the capsule body 1 When touching or penetrating near the inner surface of the tip, This is to prevent the penetrating stirrer 3 from interfering with the rod-like protrusion 2a protruding at the substantially central position of the tip of the ranger 2.

  The storage compartment 2c of the plunger 2 may have any shape as long as it has the same cross section from the insertion opening 2ca opening at the rear end to the opening opening breaking portion 2cb on the front end side. In order to prevent the second component B stored in the storage compartment 2c from leaking outside, at least a through stirring rod body 3 to be described later inserted into the storage compartment 2c may be used. The cross section corresponding to the cross section must be formed in such a shape that the penetrating stirrer 3 can be slidably inserted, and the introduction formed on the front end side of the storage compartment 2c. As the opening fracture portion 2cb, for example, as shown in FIGS. 1, 4 to 8, 10, 11, and 16 to 19, the linear portion surrounding the introduction opening fracture portion 2cb is thin except for a part. If it is formed, the through-opening stirrer 3 which will be described later with respect to the opening opening breaking portion 2cb is provided. When pushing at the tip, the other linear part is broken, leaving the thicker linear part, so the thin linear part can be easily broken with a weak force, and the opening for opening is broken. It is preferable that the portion 2cb can be prevented from being completely separated from the plunger 2 and mixed into the mixing compartment 1b of the capsule body 1.

  As the storage compartment 2c of the plunger 2, for example, only one plunger 2 may be perforated as shown in FIG. 11, but the plunger 2 as shown in FIG. 1, FIG. 3 to FIG. 8 and FIG. If a plurality of storage compartments 2c are perforated, a plurality of penetrating stirrer bars 3 to be described later are fitted into the plunger 2 so that the capsule main body 1 is covered with the plurality of penetrating stirrer bars 3 during mixing and mixing. Since the first component A and the second component B in the mixing compartment 1b can be mixed and kneaded, the mixing and kneading efficiency can be further improved. When the joint portion 4 is a plate-like embodiment fixed to the rear end side of the penetrating stirring rod 3, it is preferable that the plunger 2 can be stably rotated, and FIG. 1 and FIG. 3 through multiple storage compartments 2c as shown in FIG. If the distances from the central axis to the central axis of the plunger 2 are different from each other, a plurality of through stirring rod bodies 3 described later revolve around the central axis of the plunger 2 at different positions. Therefore, the mixing and kneading efficiency can be remarkably improved. Further, as shown in FIGS. 1 and 3 to 5, when the storage compartment 2 c is viewed from the rear end side of the plunger 2. If the first and second components A and B in the mixing body 1b of the capsule body 1 are drilled at positions at equal angles with respect to the central axis of the plunger 2, Therefore, it is preferable that the mixing and kneading efficiency can be remarkably improved. Further, as shown in FIGS. 1, 3 to 8, 10, and 11, the plunger 2 is disposed after the plunger 2. End side The first component A and the second component B in the mixing compartment 1b of the capsule body 1 if the storage compartment 2c is formed so as to be positioned near the outer peripheral edge of the plunger 2 when viewed. Since a large stirring force can be applied to the mixture, the mixing and kneading efficiency can be remarkably improved, which is preferable.

  16-19, the maximum thickness of the rod-shaped protrusion 2a from the central axis of the mixing compartment 1b of the capsule body 1 at a position away from the first pressing portion 2b and the storage compartment 2c as shown in FIGS. Further, a stirring rod through-hole 2e formed in parallel with the central axis of the mixing compartment 1b of the capsule body 1 in a shape having the same cross section from the rear end to the front end at a position distant from the circumferential side is further drilled. In addition, a plate-like rotational force transmitting engagement portion 4 (to be described later) or a plate-like second pressing portion 3a (to be described later) has a shape slidable in the through hole 2e for the stirring rod of the plunger 2 and If the length is substantially the same as that of a penetration stirring rod 3 described later and a stirring dedicated rod 6 (described later) fitted in the stirring rod through hole 2e of the plunger 2 is further fixed, the plunger 2 as described above. In the same manner as a plurality of storage compartments 2c are perforated When mixing and kneading the first component A and the second component B in the mixing compartment 1b of the main body 1 with a plurality of rod-like bodies such as a penetration stirring rod 3 described later and a stirring dedicated rod 6 described later. Since kneading can be performed, the mixing kneading efficiency can be remarkably improved, and it is preferable. The plunger 2 has an opening opening breaking portion 2cb on the tip end side, and the second component B is Compared to forming the storage compartment 2c that is stored, it is easier and less expensive to manufacture the stirring rod through-hole 2e having the same cross section from the rear end to the front end. Therefore, for example, a later-described plate-like rotational force transmission engagement portion 4 or a later-described plate-like second pressing member, to which one later-described through stirring rod body 3 and one later-described stirring-only rod body 6 are fixed. Plan with part 3a, one storage compartment 2c, and one stirring rod through hole 2e When the jar 2 is used, a plate-like rotational force transmission engaging portion 4 to be described later to which two penetration stirring bars 3 are fixed or a plate-like second pressing portion 3a to be described later and two storage sections Compared to the case of using the plunger 2 with the chamber 2c formed therein, it is preferable that the production cost can be reduced while maintaining the high mixing and kneading efficiency.

  As the through hole 2e for the stirring rod of the plunger 2, for example, only one plunger 2 may be drilled as shown in FIGS. 16, 17 and 19, but a plurality of plungers 2 may be provided in the plunger 2 as shown in FIG. If the through hole 2e for the stir bar is formed, the mixing compartment of the capsule body 1 is composed of one or a plurality of through stirrer bars 3 described later and a plurality of dedicated stirrer bars 6 described later during mixing and kneading. Since the first component A and the second component B in 1b can be mixed and kneaded, the mixing and kneading efficiency can be further improved, and although not shown, the storage compartment 2c of the plunger 2 and If the through-holes 2e for the stirring rods are bored so that the distances from the respective central axes to the central axis of the plunger 2 are different from each other, one or a plurality of through-stirring rod bodies 3 or one or more described later The stirring rod 6 to be described later is plunge It is preferable that the mixing and kneading efficiency can be remarkably improved, and the plunger 2 is further improved as shown in FIGS. 18 and 19. If the storage compartment 2c and the through hole 2e for the stirring rod are drilled at positions at equal angles to the central axis of the plunger 2 when viewed from the rear end side of the plunger 2, the capsule Since the uniform mixing force can be applied to the first component A and the second component B in the mixing compartment 1b of the main body 1, the mixing and kneading efficiency can be remarkably improved. As shown in FIGS. 18 and 19, the plunger 2 has a through hole 2 e for a stirring bar that is drilled so as to be positioned in the vicinity of the outer peripheral edge of the plunger 2 when viewed from the rear end side of the plunger 2. The capsule body It is possible to provide greater agitation force to the first component A of the mixing compartment 1b of the the second component B, preferably to be able to remarkably improve the mixing and kneading efficiency.

  As shown in FIGS. 1 to 9, 11 and 16 to 19, the plunger 2 may have a columnar shape having the same cross section from the front end to the rear end, as shown in FIG. Thus, a stopper portion 2d having a cross section larger than the cross section of the plunger 2 is formed on the rear end side of the plunger 2, and a rotational force transmitting engagement portion 4 described later has a cross section in cross section. The plunger 2 has a plate-like shape that is smaller than the cross section of the stopper portion 2d, and is fixed to the rear end side of the penetrating stir bar 3. The rear end of the penetrating stir bar 3 has a second pressing portion 3a. When the first pressing portion 2b of the plunger 2 is viewed from the rear end side of the rotational force transmission engaging portion 4, the peripheral wall of the rotational force transmission engaging portion 4 and the stopper portion 2d of the plunger 2 are If it is located between the outer peripheral wall, plate-shaped rotational force transmission engagement Not only is it preferable that the first pressing portion 2b of the plunger 2 can be pressed without processing the portion 4, but the plunger 2 itself can be enlarged, so that the capacity of the storage compartment 2c can be increased. This is preferable.

  3 is a slidable shape in the storage compartment 2c of the plunger 2, and when the second pressing portion 3a at the rear end is pressed toward the front end side, the opening opening break portion for introduction of the storage compartment 2c of the plunger 2 at the front end. 2cb is pushed through and the second component B is introduced into the mixing compartment 1b of the capsule body 1 and the tip thereof abuts on the tip inner surface of the mixing compartment 1b of the capsule body 1 or penetrates to the vicinity of the tip inner surface. In this way, the second stirring portion 3a at the rear end of the penetrating stir bar inserted into the storage compartment 2c of the plunger 2 is pressed toward the distal end, so that the distal end of the storage compartment 2c of the plunger 2 is While pushing through the opening breaking portion 2cb for introduction, the second component B is introduced into the mixing compartment 1b of the capsule body 1, and the second pressing portion 3a is further pushed toward the distal end side so that the inside of the storage compartment 2c of the plunger 2 is reached. The tip of the capsule body When the rotational force is applied to the rotational force transmitting engagement portion 4 to be described later in a state where it abuts on the inner surface of the front end of the mixing compartment 1b or is penetrated to the vicinity of the inner surface of the front end, the plunger 2 has its central axis Is rotated around the central axis of the plunger 2 in the mixing compartment 1b while being integrated with the plunger 2 with the penetrating stirring bar 3 protruding from the tip of the plunger 2. By being moved, the first component A and the second component B in the mixing compartment 1b of the capsule body 1 are mixed and kneaded so as to be directly stirred.

  As shown in FIGS. 1, 4 to 8, 10, 11, and 16 to 19, the penetrating stirring bar 3 has a shape that can be slidably fitted into the storage compartment 2 c of the plunger 2, that is, The cross section only needs to have a shape corresponding to the cross section of the storage compartment 2c of the plunger 2, and the length of the penetrating stirrer 3 in the longitudinal direction is that the plunger 2 is the tip in the capsule body 1. In the initial position before being pushed to the side, the penetrating stirrer 3 was pushed to the tip side to push the opening opening breaking portion 2cb for introduction of the storage compartment 2c of the plunger 2 with the tip. Later, when it is further pressed to the tip side and can no longer slide to the tip side, i.e., pressed until it can no longer slide to the tip side by being directly or indirectly positioned, At least the tip of the capsule body 1 is mixed Compartment 1b of the above long as it enters the distal inner surface up or its tip near the inner surface abuts the at the may have a length.

  The penetration stirring bar 3 pushes through the opening opening breaking portion 2cb for introduction of the storage compartment 2c of the plunger 2 at the tip, and the shape of the penetration stirring bar 3 on the tip side is a storage compartment. There is no particular limitation as long as it has a shape that can push through the introduction opening fracture portion 2cb of the chamber 2c.For example, the introduction opening fracture portion 2cb has a linear portion surrounding the introduction opening fracture portion 2cb as described above. In the case of a thinly formed form leaving a part, when the introduction opening breaking part 2cb is pushed through the tip of the penetrating stirrer bar 3, other thicker linear parts are left behind. Since this part can be easily broken with a weak force, the tip of the penetrating stirrer 3 made of a solid bar-like body is simply cut in a direction perpendicular to the axial center. Such a shape or a rounded shape may be used, and FIGS. 10, 11, 18, and 19, the penetrating stirrer 3 may be of a sharp shape in which the tip of the penetrating stirrer 3 made of a solid bar is cut obliquely. In this case, it is preferable that the introduction opening fracture portion 2cb of the storage compartment 2c can be surely pushed.

When the portion 3a is pressed toward the tip side and the tip abuts against the inner surface of the front end of the mixing compartment 1b of the capsule body 1 or is penetrated to the vicinity of the inner surface of the tip, the rear end of the storage rod-like portion 3b is a plunger. 2 is formed in such a length as to reach the vicinity of the opening opening rupture portion 2cb of the storage compartment 2c, and the opening opening rupture portion 2cb of the storage compartment 2c of the plunger 2 is pushed by the thin rod-like portion 3b for storage. The second component B stored in the storage compartment 2c of the plunger 2 is almost left if it is torn and its cross-sectional area is slightly larger than the cross-sectional area of the storage rod-like portion 3b. In the mixing compartment 1b of the capsule body 1 In addition to being preferable, the cross-sectional area of the opening opening breaking portion 2cb of the storage compartment 2c of the plunger 2 is slightly larger than the cross-sectional area of the thin rod-shaped portion 3b for storage. Therefore, when the mixture C mixed and kneaded is discharged by pressing the first pressing portion 2b of the plunger 2 toward the tip side, the mixture C does not flow back into the storage compartment 2c of the plunger 2, The kneaded mixture C is preferred because it can be used without waste.

  Further, as shown in FIGS. 12 and 13, the front end side of the penetrating stirrer bar 3 has a cylindrical shape that is obliquely cut off at the front end of the solid penetrating stirrer bar 3, and 14 and 15 may be formed of a flexible material that can be pushed through the introduction opening breaking portion 2cb and crushed when it comes into contact with the inner surface of the front end of the mixing compartment 1b of the capsule body 1. As shown in the figure, a sliding thin rod portion 3c having a cross section whose cross-sectional area is smaller than that of the rear end side is formed on the front end side of the through stirring rod body 3, and the cross section The outer periphery has the same shape as the outer periphery of the cross section of the penetrating stirrer 3 and its tip is formed into a cylindrical shape with a diagonal cutout. Located in a state protruding from the tip of the part 3c and storing the plunger 2 A break-through portion 3d configured to slide to the rear end side when the opening opening portion 2cb for introduction of the compartment 2c is pushed through and contacted with the inner surface of the front end of the mixing compartment 1b of the capsule body 1 is externally fitted. In this case, not only is it possible to reliably break the opening breaking portion 2cb for introduction of the storage compartment 2c of the plunger 2 even with a weak pressing force, it is preferable, but the tip of the penetrating stirring rod 3 is connected to the capsule body 1 Can be reliably infiltrated until it comes into contact with the inner surface of the front end of the mixing compartment 1b, so that the mixing and kneading efficiency can be remarkably improved and the inner surface of the front end of the mixing compartment 1b of the capsule body 1 and the through stirring Since the tip of the rod 3 abuts, the mixture C in the mixing compartment 1b of the capsule body 1 can be pushed out in a state where it does not remain in the mixing compartment 1b, which is economical and preferable.

  The rear end of the penetrating stir bar 3 has a second pressing portion 3a that is pressed toward the tip side. As the second pressing portion 3a, the penetrating stir bar 3 is pressed toward the tip side. Any shape can be used as long as it is possible, for example, the rear end of the penetrating stirring rod 3 made of a solid rod-like body is simply cut or rounded in a direction perpendicular to the axis. However, as shown in FIG. 11, the cross section of the second pressing portion 3a is larger than the cross section of the penetrating stirring rod 3 that slides in the storage compartment 2c of the plunger 2. If there is, the penetrating stirrer 3 is pressed toward the tip side, and the tip breaks the opening opening breaking portion 2cb for introduction of the storage compartment 2c of the plunger 2 to break the second component B into the mixing compartment 1b of the capsule body 1 The tip of the penetrating stirrer 3 becomes the capsule body when it is further slid to the tip side after being introduced into Mixing or abuts on the tip inner surface of the compartment 1b or in a state where allowed penetrate the tip near the inner surface, preferably be capable of positional regulation so as not to be any more slides distally.

Thus, the first component A and the second component B in the mixing compartment 1b are mixed and kneaded as a mixture C so as to be directly stirred.

  This stirring rod 6 is slidable in the stirring rod through-hole 2e of the plunger 2 and is fitted in the stirring rod through-hole 2e of the plunger 2, and its rear end side has a plate-like rotational force. Further, it is fixed to the transmission engaging portion 4 or the plate-like second pressing portion 3a. For example, as shown in FIGS. 16, 17 and 19, the plunger 2 has one through hole 2e for the stirring rod. In this case, one stirring-only bar 6 is fixed to the rotational force transmission engaging portion 4 or the plate-like second pressing portion 3a so as to correspond to the position of the through-hole 2e for the stirring rod. As shown in FIG. 18, when there are a plurality of stirring rod through holes 2e in the plunger 2, the plurality of stirring dedicated rod bodies 6 correspond to the positions of the respective stirring rod through holes 2e. It is fixed to the 4 or plate-like second pressing part 3a.

  Since the length of the stirring-only bar 6 is substantially the same as that of the penetrating stirring bar 3, the opening breaking portion 2 cb for introduction of the storage compartment 2 c of the plunger 2 is pushed at the tip of the penetrating stirring bar 3. After breaking and introducing the second component B into the mixing compartment 1b of the capsule body 1, the second pressing portion 3a is further pushed toward the distal end, sliding inside the storage compartment 2c of the plunger 2 and penetrating through. In the state in which the tip of the rod 3 is in contact with the inner surface of the tip of the mixing compartment 1b of the capsule body 1 or is intruded to the vicinity of the inner surface of the tip, the tip of the stirring-only rod 6 is also the capsule body 1 as shown in FIG. That is, it comes into contact with the inner surface of the front end of the mixing compartment 1b or penetrates to the vicinity of the inner surface of the front end.

  As the stirring-only rod 6, as shown in FIGS. 16 to 18, the plunger 2 has a rod-like shape at a position away from the first pressing portion 2 b and the storage compartment 2 c and from the central axis of the mixing compartment 1 b of the capsule body 1. A stir bar penetrating hole formed parallel to the central axis of the mixing compartment 1b of the capsule body 1 in the shape of the same cross section from the rear end to the tip at a position more than the maximum thickness of the protrusion 2a on the circumferential side A hole 2e is further drilled, and the plate-like rotational force transmission engaging portion 4 is formed so as to be slidable in the through hole 2e for the stirring rod of the plunger 2, and its length is the through stirring rod body 3 And the first pressing portion 2b and the storage section are arranged on the plunger 2 as shown in FIG. 19, in which the stirring-only rod 6 fitted in the through-hole 2e for the stirring rod of the plunger 2 is further fixed. The center of the mixing compartment 1b of the capsule body 1 at a position away from the chamber 2c Agitation formed parallel to the central axis of the mixing compartment 1b of the capsule body 1 in the shape of the same cross section from the rear end to the tip at a position separated from the axis to the circumferential side more than the maximum thickness of the rod-shaped protrusion 2a A through hole 2e for the rod is further drilled, and the plate-like second pressing portion 3a is formed to be slidable in the through hole 2e for the stirring rod of the plunger 2, and its length is the through stirring rod. There is a mode in which the stirring-only rod body 6 that is substantially the same as the body 3 and is inserted into the through-hole 2e for the stirring rod of the plunger 2 is further fixed, and in any mode, the mixing and kneading efficiency is remarkably improved. This is not only preferable, but also compared with the case where the plunger 2 has the opening opening portion 2cb for introduction at the tip side and the storage compartment 2c in which the second component B is stored. For stirring rods with the same cross section from the rear end to the front end Because and manufacturing cost is easier to form a throughbore 2e it is inexpensive, preferable can be cheaper the production cost while keeping its high mixing and kneading efficiency.

Next, the usage method of the capsule for tooth restoration materials which concerns on this invention of such a structure is demonstrated.
First, as a preparation, a capsule for a tooth restoration material according to the present invention contains a first component A in a mixing compartment 1b of the capsule body 1 and a storage compartment 2c of a plunger 2 as shown in FIG. The assembly operation is performed so that the second component B is stored in the container.

  For example, after the first component A is first stored in the mixing compartment 1b of the capsule body 1, the plunger 2 is inserted into the capsule body 1 from the rear end side, and then in the storage compartment 2c of the plunger 2. After the second component B is stored in the insertion port 2ca at the rear end, the penetration stirring bar 3 is further inserted into the storage compartment 2c from the front end side of the insertion port 2ca at the rear end. This is done by fixing or mounting the nozzle 5 on the tip.

  In addition, this operation may be performed by a mode in which a plurality of penetration stirring rods 3 are fixed to the plate-like rotational force transmission engaging portion 4 or the plate-like second pressing portion 3a, or one or more penetration stirring rods. In an embodiment in which three and one or a plurality of stirring-only rods 6 are fixed, for example, the first component A is first stored in the mixing compartment 1b of the capsule body 1, and then the capsule body 1 is inserted into the capsule body 1 from the rear end side. The plunger 2 is inserted, and then the second component B is stored in the storage compartment 2c of the plunger 2 from the insertion port 2ca at the rear end, and then the penetration stirring rod is inserted into the insertion port 2ca at the rear end of the storage compartment 2c. 3 and if there is a through-hole 2e for the stirring rod, the tip of the stirring-only rod 6 is also inserted into the opening at the rear end of the through-hole 2e for the stirring rod and the plate-like rotational force transmission mechanism By pressing the joint part 4 or the plate-like second pressing part 3a toward the distal end, Is fitted the 拌専 for rod 6, is performed by fixing or attaching the nozzle 5 at the end to the distal end portion of the capsule body 1.

  These series of assembly operations are usually performed in a factory, and the order of these series of assembly operations may be changed.

  After preparing the capsule for a tooth restoration material according to the present invention, first, the second pressing portion 3a at the rear end of the penetrating stirrer bar 3 is pressed to the front end side, whereby the plunger is formed at the tip of the penetrating stirrer bar 3. The second opening B is introduced into the mixing compartment 1b of the capsule body 1 by pushing through the opening opening breaking portion 2cb of the storage compartment 2c of the storage compartment 2c, and the tip of the penetrating stirring bar 3 is the mixing compartment of the capsule body 1 An operation is made to contact the inner surface of the tip of 1b or to penetrate to the vicinity of the inner surface of the tip.

  Specifically, when the second pressing portion 3a at the rear end of the penetrating stirring bar 3 is pressed toward the tip, first, the tip of the penetrating stirring bar 3 is moved into the storage compartment 2c of the plunger 2 from the state shown in FIG. When it slides to the leading end side and reaches the opening rupture portion 2cb for introduction of the storage compartment 2c of the plunger 2, the opening rupture portion 2cb for introduction is pushed and opened at the tip, and the opening rupture portion 2cb for introduction opened. The second component B stored in the storage compartment 2c is pushed out and introduced into the mixing compartment 1b of the capsule body 1.

  And in this state where the second component B is introduced into the mixing compartment 1b of the capsule body 1 by piercing through the opening breaking portion 2cb for introduction of the storage compartment 2c of the plunger 2 with the through stirring bar 3 in this way, Further, when the second pressing portion 3a at the rear end of the penetrating stirring bar 3 is pressed toward the tip side, the tip of the penetrating stirring bar 3 comes into contact with the inner surface of the tip of the mixing compartment 1b of the capsule body 1 or in the vicinity of the inner surface of the tip. As shown in FIG. 4, the tip of the penetrating stirring bar 3 protrudes from the tip of the plunger 2 in the mixing compartment 1 b of the capsule body 1.

  At this time, for example, as shown in FIG. 11, the cross section of the second pressing portion 3 a of the through stirring bar 3 is formed larger than the cross section of the through stirring bar 3 sliding in the storage compartment 2 c of the plunger 2. If it is, the rear end side of the second pressing portion 3a may be pressed, and a plate-like shape is formed on the rear end side of the penetrating stirring rod 3 as shown in FIGS. 1 to 5 and FIGS. In the case of a mode in which the rotational force transmission engaging portion 4 forming the above is fixed and the rear end thereof forms the second pressing portion 3a of the penetrating stirring rod 3, the plate-like rotational force transmission engaging portion 4 is formed.
