Description

Territory of invention

These The invention relates to a capsule for two-component materials, more precisely a capsule for two or more components of a material to be mixed. The material may be a dental material, such as an impression material, a temporary one Restoration material or a filling material.

description of the prior art

in the Dental area, so with dentists and dental technicians, are various capsules for intraoral application of materials from one component or from two or more to mixing components known. There are the so-called "Compules", there are the liquid-powder capsules, and there are the paste-paste capsules.

The Compule is a capsule having a cannula, a single chamber containing a one-component material and leading into the cannula at the front, and a piston seated in the rear of the chamber. Such Compules include, for example, the Filtek ^™ Supreme universal restorative and the Filtek ^™ Z250 universal composite from 3M ESPE. They must be used for application in an applicator, available for example from 3M ESPE as a dispenser, under item number 5706 SD or from Centrix ^TM . These known applicators each have a body with a handle, a holder for removably receiving the compute, a plunger and a drive for the plunger. When the capsule is in the holder and the drive is operated by closing the hand, then pushes the plunger from behind into the chamber so that it first rests against the piston and further advances him. By the piston feed, the material is discharged from the chamber through the cannula. Such compute applicators are very widespread in the market.

The liquid-powder capsules contain a liquid and a powdery component, which are to be kept separate from each other until use. Such liquid-powder capsules are available, for example, under the names Aplicap ^™ and Maxi cap ^™ from 3M ESPE. These capsules include, for example, the two components of restorative materials to be blended, such as the Ketac ^™ Molar glass ionomer pad or the Photac ^™ Fil Quick photocuring glass ionomer pad, or the Ketac ^™ Silver Molar silver reinforced glass ionomer pad, or from fixing cements, such as the self-adhesive universal composite luting cement RelyX ^TM Unicem or the adhesive composite luting cement Compolute ^™ or the glass ionomer luting cement Ketac ^{T M} Cem. These known capsules include a cannula, a spacious mixing chamber containing the powder and leading into the cannula, a plunger located at the rear of the mixing chamber, and a foil pad containing the fluid covering a hole in the shell wall of the chamber , For use, the capsule is first activated by applying pressure to the foil cushion in a suitable manner so that it ruptures over the hole and the liquid is forced into the mixing chamber. The mixing chamber is larger than the combined volume of the two components, so that they can be mixed by vigorous shaking, for example by means of the capsule blenders RotoMix ^™ or CapMix ^™ from 3M ESPE. Subsequently, they must be inserted into a suitable applicator, which is available, for example, under the name Aplicap ™ Applier or Maxicap ^™ Applier from 3M ESPE. These known applicators each have a body with a handle, a holder for removably receiving the capsule, a plunger and a drive for the plunger. When the capsule is seated in the holder and the actuator is actuated by closing the hand, it pushes the plunger from behind into the mixing chamber, so that it first rests against the piston and advances it further. By the piston feed, the material is discharged from the mixing chamber through the cannula. Such liquid-powder capsule applicators are also widely used in the marketplace.

The paste-paste capsules contain two pasty components which are to be kept separate from each other until use. Such a paste-paste capsule is known from WO-97/21394, which also discloses an applicator for this capsule. This known capsule comprises a cannula, a static mixer sitting in the cannula, two adjacent cylindrical chambers which open into the front of the cannula, and two cylindrical pistons which are movably seated in the rear of the chambers. The known applicator comprises a body with a handle, a holder for removably receiving the capsule, two elongate, juxtaposed plunger and a drive for the two plungers, which, when the capsule is in the holder, from behind into the two chambers advances. The chambers contain the two paste-like components which are forced out of the chambers into the cannula when the applicator drive is actuated by the two pistons, which are pushed further into the chambers by the two plungers. As it continues to flow through the cannula, the two component strands are mixed by the mixer and finally mixed tes material out front of the cannula.

The from WO-97/21394 known paste-paste capsule can neither with the previously described known Compule applicators still with the previously described known applicators for liquid-powder capsules, the yes both are widely used in the market, since these are used each have only a single plunger, the well-known paste-paste capsule but has two pistons.
