Dental container with vapor-tight, sealable dropper insert

Abstract

A drop system made of a liquid to be provided in drop form in the field of dentistry is contained in a container with a vapor-tight, sealable dropper insert made of light-impermeable plastic and a hollow space running in the dropper insert provided for the supply of a liquid. The hollow space has several tubular sections and a funnel-shaped outlet. The tubular section connecting to the funnel is formed as a tapering or restriction between the funnel-shaped section and another tubular section, and the funnel is arranged in a column-shaped dropper spout. A collection channel is arranged on the outer side of the dropper between the outer wall defining the hollow space and the part of the dropper insert covering the neck of the bottle.

       7 . A dropper system for a liquid to be provided in drop form in dental applications, the dropper system comprising a container having a vapor-tight, sealable dropper insert made of light-impermeable plastic and a passage running in the dropper insert for providing a supply of a liquid, the passage being formed in a column-shaped dropper spout comprising several tubular sections and a funnel-shaped outlet, wherein one of the tubular sections, which connects to the funnel-shaped outlet, has a passage form of a tapering or restriction between the funnel-shaped outlet and another tubular section, and a collection channel arranged on an outside of the dropper between an outer wall limiting the passage and a part of the dropper insert covering a container rim at a container opening. 
   
   
       8 . The drop system according to  claim 7 , wherein the outer wall  3  has an outer sharp edge for an annular face. 
   
   
       9 . A liquid dropper comprising a vapor-tight, sealable dropper insert made of light-impermeable plastic and having a passage running in the insert for supply of a liquid to be used in drop form for dental applications, wherein the passage is formed by several tubular sections and a funnel-shaped outlet, wherein one of the tubular sections, which connects to the funnel-shaped outlet, has a passage form of a tapering or restriction between the funnel-shaped outlet and another tubular section. 
   
   
       10 . A dropper for use with a container filled with a liquid designed for a dental use, the dropper comprising a vapor-tight, sealable dropper insert made of light-impermeable plastic and having a passage running in the insert for supply of the liquid, and a collection channel arranged on an outer side of the dropper between an outer wall defining the passage and a part of the dropper insert covering a container rim at a container opening. 
   
   
       11 . A method for producing a dental adhesive drop, the method comprising conducting a dental adhesive through a column-shaped dropper spout, such that the adhesive first runs through a tubular region, then passes through a tapering or restriction, whereupon the liquid passes from the tapering or restriction to a funnel-shaped expansion in which a drop is formed. 
   
   
       12 . The method according to  claim 11 , wherein the tubular region has an inner diameter of 2 to 10 mm and the tapering or restriction has an inner diameter of 0.2 to 2.0 mm. 
   
   
       13 . A method for producing a dental adhesive drop, the method comprising conducting a liquid dental adhesive through a column-shaped dropper spout, such that the adhesive first runs through a tubular region, then passes through a tapering or restriction, whereupon the adhesive passes from the tapering or restriction to a funnel-shaped expansion, and from the expansion a drop is formed and conducted to an end face of the spout and from the end face the drop is discharged. 
   
   
       14 . The method according to  claim 13 , wherein the tubular region has an inner diameter of 2 to 10 mm, and the tapering or restriction has an inner diameter of 0.2 to 2.0 mm.
