Embodiment Construction

[0029] The present invention provides a unit dose package for a dental composition. The dental composition is preferably a dental composition with low viscosity. In particular, a dental composition having a dynamic viscosity at 23°C of at most 1 Pas, preferably at most 100 mPas, more preferably at most 50 mPas. The dental composition contains one or more solvents, preferably selected from water, alcohols or ketones. The dental composition is preferably one selected from the group consisting of dental adhesives, desensitizers, pit and crack sealants and protective varnishes. Preferably, the dental composition is a dental adhesive, more preferably a dental adhesive comprising one or more solvents selected from alcohols, ketones and water. In a preferred embodiment, the dental composition is a dental adhesive comprising one or more solvents selected from the group consisting of 1-propanol, 2-propanol, ethanol, t-butanol, methyl ethyl ketone, acetone and water. In a more prefer...

Abstract

A unit dose package for a dental composition, comprising: (a) a rigid support member having a proximal end and a distal end, the rigid support member supporting one or more storage compartments for the dental composition and providing fluid flow communication between the one or more storage compartments and one or more discharge orifices, wherein the one or more storage compartments each have a volume of 10 pi to 1000 pi, and (b) a discharge conduit having a longitudinal axis extending from a proximal end to a distal end, the discharge conduit being rotatably attached to the distal end of the rigid support member for rotation around its longitudinal axis, wherein the attachment of the discharge conduit (b) and the rigid support member (a) is provided by two-component injection molding; whereby fluid flow communication between the discharge conduit and the one or more storage compartments may be established by rotating the discharge conduit around its longitudinal axis relative to the rigid support member from a first position to a second position and whereby the fluid flow communication between the discharge conduit and the one or more storage compartments may be interrupted by rotating the discharge conduit around its longitudinal axis relative to the rigid support member from the second position to the first position, wherein the one or more storage compartments are provided by flexible films made of composite material films, which are attached to the rigid support member.

Description

technical field [0001] The present invention relates to a unit dose package for a dental composition. The unit dose packages may contain a single component or two or more components. Unit dose packages of the invention may be suitable for admixing two or more components. [0002] Furthermore, the invention relates to a process for the preparation of the unit dose package of the invention. [0003] Finally, the invention relates to the use of the unit dose package of the invention for dispensing dental compositions, specifically dental adhesives. Background technique [0004] Dental compositions (specifically, dental adhesives) require polar solvents in order to be able to wet the tooth surface. In addition, the solvent needs to be volatile so that it can be eliminated prior to curing the dental composition. Accordingly, the dental adhesive composition may include an organic water-soluble solvent and / or water. The organic water-soluble solvent may be selected from volati...
