Abstract

Abstract The invention relates to a dispenser for dispensing light curable substances, such as substances used for various dental applications. The dispenser includes a body defining a dispensing formation, the body and dispensing formation being designed to cooperate with a closure, such as a lid, for closing-off the dispensing formation and thereby isolating light curable substances contained in the dispensing formation from light. A charging opening may also be defined by the body, that leads into the dispensing formation and permits charging of light curable substance into the formation by means of a syringe, or the like, in which these substances are generally contained.

A dispenser for dispensing light curable substances, which includes: a body in the form of a box; at least one dispensing formation into which a light curable substance can be charged from a storage container for dispensing purposes, said dispensing formation being in the form of a recess within said box, said recess being at least partially dish-shaped to facilitate dispensing of said light curable substance therefrom for dental applications by a dentist; closure means for closing off said dispensing formation and isolating any light curable substance therein from light; and means for locating and holding said storage container within said body during and subsequent to charging, said locating and holding means including a charging opening in the box through which said light curable substance can be charged into said recess from said storage container, said storage container being a storage syringe, with said charging opening being adapted to receive, locate and hold said syringe body therein, with the end through which said substance can be dispensed from the syringe being in communication with said recess.
Claim 2
Dependent Claim 176 words
A dispenser for dispensing light curable substances, which includes: a body in the form of a box; at least one dispensing formation into which a light curable substance can be charged from a storage container for dispensing purposes, said dispensing formation being in the form of a recess within said box, said recess being at least partially dish-shaped to facilitate dispensing of said light curable substance therefrom for dental applications by a dentist; closure means for closing off said dispensing formation and isolating any light curable substance therein from light; and means for locating and holding said storage container within said body during and subsequent to charging, said locating and holding means including a charging opening in the box through which said light curable substance can be charged into said recess from said storage container, said storage container being a storage syringe, with said charging opening being adapted to receive, locate and hold said syringe body therein, with the end through which said substance can be dispensed from the syringe being in communication with said recess.
Claim 3
Dependent Claim 75 words
A dispenser as claimed in claim 1, wherein the closure means is a lid that is slidably displaceable with respect to the body between an open position, in which access into the dispensing formation is provided for, and a closed position, in which the formation is closed off, the lid being of an opaque material thereby to isolate any substance contained within the dispensing formation from light when the lid is in its closed position.
Claim 4
Dependent Claim 55 words
A dispenser according to claim 1, wherein the body is in the form of a drawer, with the closure means being a drawer holder within which the body is slidably receivable, the drawer holder being of an opaque material so that any substance contained within the dispensing formation of the body is isolated from light.
Claim 5
Dependent Claim 30 words
A dispenser as claimed in claim 1, in which the body is connectable to additional similar bodies to form a dispenser for dispensing two or more different light curable substances.
Claim 6
Dependent Claim 39 words
A dispenser as claimed in claim 1, which includes at least one zone on the body and the closure means, the zone being adapted to have suitable markings applied thereto whereby substances contained within the body can be identified.
Claim 7
