Refill system of a liquid container

Abstract

Refill system of a liquid container, where a conduit element is fixed to the liquid container and has an upper part flow passage having one end inside the container and the other end leading past the connection of the conduit element with the container and through at least one upper part radial opening into a space defined by the conduit element and the wall of the container, and wherein, in its first position, a closing element having a first sealing portion is capable of sealing the space liquid-tightly towards the outside.

1 . Refill system of a liquid container, preferably a flacon, comprising
 a conduit element capable of communicating the inside with the outside of the liquid container and being liquid-tightly connected to the liquid container, and   a closing element capable of being in a first position which prevents a liquid flow through the conduit element and a second position which allows a liquid flow through the conduit element, wherein,   the conduit element is fixedly connected to the liquid container and has an upper part with an upper part flow passage having one end inside the liquid container and the other end leading past the liquid-tight connection of the conduit element with the liquid container and subsequently through at least one upper part radial opening into a space defined by the conduit element and the wall of the liquid container,   in its first position, the closing element having a first sealing portion is capable of sealing the space defined by the conduit element and the wall of the liquid container liquid-tightly towards the outside.   
     
     
         2 . Refill system according to  claim 1 , wherein
 the conduit element has a lower part with a lower part flow passage that is symmetrical to the upper part flow passage and connected through at least one lower part radial opening to the space defined by the conduit element and the wall of the liquid container, when the closing element is in its second position and sealing the space defined by the conduit element and the wall of the liquid container liquid-tightly towards the outside, and   the conduit element is capable of receiving a stem of a liquid donor tank by abutment to its lower part.   
     
     
         3 . Refill system according to  claim 2 , wherein
 a sealing element is placed inside the lower part flow passage and interposed between the at least one lower part radial opening and the lower part flow passage,   being capable of sealing the lower part flow passage liquid-tightly towards the outside by gravity and/or liquid pressure entering through the at least one radial opening, and   being capable of letting liquid from the outside through the lower part flow passage and the at least one lower part radial opening.   
     
     
         4 . Refill system according to  claim 1 , wherein
 the closing element having a second sealing portion by means of which it is capable of closing, in its first position, a ventilation passage communicating the inside with the outside of the liquid container, and is capable of opening, in its second position, the ventilation passage.   
     
     
         5 . Refill system according to  claim 4 , wherein
 in the first position of the closing element, the second sealing portion is interposed between the wall of the liquid container.   
     
     
         6 . Refill system according to  claim 4 , wherein
 the closing element seals the ventilation passage from the flow passageby means of the first sealing portion.   
     
     
         7 . Refill system according to  claim 1 , wherein
 the closing element is held movably on the conduit element to assume either one of the first and second position.   
     
     
         8 . Refill system according to  claim 1 , wherein
 the closing element is capable of being unlocked from its first position by being rotated and subsequently moved away from the liquid container into its second position.   
     
     
         9 . Refill system according to  claim 1 , wherein
 the closing element is capable of being pushed toward the liquid container and subsequently turned and locked into its first position.   
     
     
         10 . Refill system according to  claim 1 , wherein
 the closing element is held   in its first position, by abutment against a first step portion on the distal side of the conduit element facing the liquid container, and   in its second position, by gravity abutment against a second step portion being farther away from the liquid container than the first step portion.   
     
     
         11 . Refill system according to  claim 10 , wherein
 an elastic element interposed between the closing element and the liquid container biases the closing element respectively against the first or second step portion ( 29 ,  25 ).   
     
     
         12 . Refill system according to  claim 11 , wherein
 the elastic element is placed liquid permeably inside the space defined by the conduit element and the wall of the liquid container.   
     
     
         13 . Refill system according to any  claim 1 , wherein
 the conduit element has a ring-like edge on its distal end of the lower part being capable of being removably attached to a cover element for further protection of the refill system and/or liquid container and/or serving as an abutment for the closing element in its second position.   
     
     
         14 . Refill system according to  claim 1 , wherein
 the closing element is retracted into a flange portion of the liquid container when being in the first position, and   the closing element has a lateral or distal gripping area which protrudes from the liquid container in the first position of the closing element and allows a manual handling of the closing element in order to move it into its second position and vice versa.   
     
     
         15 . Perfume bottle with a refill system according to  claim 1 .
