Mixing capsule
View Patent ↗A mixing capsule, especially for the production of dental materials, comprises a cartridge that is closed on one end by a piston. The piston has a hemispherical recess that forms a secondary chamber and is closed off from the main chamber of the cartridge by a separating device. A body that is provided in the initial state in the main chamber is used to facilitate the mixing process and to penetrate the separating device at the beginning of the process, whereby the main chamber and the secondary chamber form a single mixing area. The body preferably disintegrates during the mixing process.
1. A mixing capsule, comprising:
a first end;
an ejection sleeve in fluid communication with said first end;
a second end opposite said first end and defined by a piston;
a separating device disposed between said first and second end;
a main chamber disposed between said first end and said separating device;
a secondary chamber disposed between said second end and said separating device;
at least one body provided in said main chamber;
a first component provided in said main chamber; and
a second component provided in said second chamber,
wherein said piston comprises a deformable material;
wherein said at least one body can penetrate said separating device; and
wherein said at least one body has an outward shape which changes during use of the mixing capsule.
2. A mixing capsule according to claim 1 , wherein said outward shape of said at least one body is selected from the group consisting of spherical, ellipsoid and angular.
3. A mixing capsule according to claim 1 , wherein said first component comprises said at least one body.
4. A mixing capsule according to claim 1 , wherein said separating device is subjected to a preparation process prior to use to form at least one rupture joint.
5. A mixing capsule according to claim 4 , wherein said rupture joint forms a shape selected from the group consisting of star-shaped, branched in a star-shaped pattern, and cone-shaped.
6. A mixing capsule according to claim 1 , wherein a frictional force between said piston and an exterior wall defining said main chamber is less than a deforming force required to deform said piston.
7. A mixing capsule according to claim 1 , wherein said deformable material of said piston comprises at least one of metals or synthetics.
8. A mixing capsule according to claim 1 , wherein said piston is tubular and comprises coaxial indentations on two sides.
9. A mixing capsule according to claim 1 , wherein said separating device comprises at least one item selected from the group consisting of a metal-containing foil, a hydrocarbon-containing layer, and a ceramic barrier layer.
10. A mixing capsule according to claim 9 , wherein said ceramic barrier layer comprises SiO X .
11. A method of mixing a dental material, comprising:
providing components of a dental material in a mixing capsule according to claim 1 ; and
accelerating said mixing capsule.
12. A method of using a mixing capsule, comprising:
inserting the mixing capsule into a capsule holder of a mixing device;
accelerating the mixing capsule through at least one of translatory movement and rotatory movement;
removing the mixing capsule from said mixing device; and
releasing at least one content of said mixing capsule,
wherein said mixing capsule comprises a cartridge separated into at least two chambers by a separating device, at least one freely movable body capable of penetrating said separating device, an ejection sleeve in fluid communication with said cartridge, and a piston displaceably disposed in said cartridge; and
wherein said at least one content of said mixing capsule is released by displacing said piston to force said at least one content out of said cartridge through said ejection sleeve.
13. A method of using a mixing capsule according to claim 12 , wherein a first dental material component is disposed in a first chamber of said mixing capsule, and a second dental material component is disposed in a second chamber of said mixing capsule.
14. A method of using a mixing capsule according to claim 13 , wherein said first dental material component comprises said at least one freely movable body.
15. A method of using a mixing capsule according to claim 12 , wherein said piston is deformable.
16. A method of using a mixing capsule according to claim 15 , wherein a frictional force between said piston and said cartridge is less than a force required to deform said deformable piston.
17. A method of making a mixing capsule for a dental material, comprising:
forming a main chamber and a secondary chamber separated by a separating device;
providing a first component in said main chamber;
providing a second component in said secondary chamber;
providing at least one body in said main chamber,
wherein a portion of said second chamber not defined by said separating device comprises a deformable piston; and
wherein said at least one body is configured to penetrate said separating device.
18. A method of using a mixing capsule, comprising:
providing a body comprising a first component of a dental material in a main chamber of a mixing capsule;
providing a second component of a dental material in a secondary chamber of said mixing capsule, which secondary chamber is defined in part by a deformable piston;
providing a separating device between said main chamber and said secondary chamber, said separating device defining portions of the secondary chamber not defined by the deformable piston;
placing said mixing capsule in a mixing device; and
accelerating said mixing capsule with consequent movement of said body to penetrate said separating device.
