Refill system

Abstract

A refill system is disclosed. The refill system having a container structure, having a wall with a refill opening, and a sealing structure, wherein the sealing structure is held by the container structure movably along the wall with the refill opening and is movable between a first position, which closes the refill opening, and a second position, which opens the refill opening.

What is claimed is: 
     
         1 . A refill system comprising a container structure, having a wall with a refill opening, and a sealing structure, wherein the sealing structure is held by the container structure movably along the wall with the refill opening and is movable between a first position, which closes the refill opening, and a second position, which opens the refill opening. 
     
     
         2 . A refill system according to  claim 1 , wherein the sealing structure is held inside the container structure so that it does not protrude from the outer circumference of the container structure. 
     
     
         3 . A refill system according to  claim 2 , wherein the sealing structure is held slidably movable between the inner wall with the refill opening and an outer wall of the container structure. 
     
     
         4 . A refill system according to  claim 3 , wherein the outer wall is part of a container enclosure, which is fixedly attached to the outside of a liquid container, wherein both, the container enclosure and the liquid container, form part of the container structure. 
     
     
         5 . A refill system according to  claim 4 , wherein the container enclosure is fixedly attached to the outside of the liquid container at the side with the wall with the refill opening. 
     
     
         6 . A refill system according to  claim 5 , wherein the container enclosure is cone-shaped and basically corresponds to the shape of the liquid container at its side with the wall with the refill opening, such that the container enclosure can be put onto the liquid container with its base portion forming the outer wall. 
     
     
         7 . A refill system according to  claim 6 , wherein the sealing structure comprises a container seal with at least one clearance hole, preferably two clearance holes, more preferably three clearance holes, wherein the container seal is biased against the wall with the refill opening from the container structure by means of at least one elastic element such that the container seal is in liquid-tight contact with the wall. 
     
     
         8 . A refill system according to  claim 7 , wherein the sealing structure is held in its first position by form fit of a locking element with the container structure so that a movement of the sealing structure along the wall with the refill opening is prevented. 
     
     
         9 . A refill system according to  claim 8 , wherein the form fit of the locking element with the container structure is held by an locking elastic element which biases the locking element in a direction towards the container structure. 
     
     
         10 . A refill system according to  claim 9 , wherein a pushing force on the locking element against the biasing locking elastic element releases the form fit and thus allows a movement of the sealing structure along the wall with the refill opening into its second position. 
     
     
         11 . A refill system according to  claim 10 , wherein the sealing structure is biased from the inside of the container structure in a direction along the wall with the refill opening by means of a releasing elastic element. 
     
     
         12 . A refill system according to  claim 11 , wherein the sealing structure comprises a conduit element which is liquid-tightly connected to the refill opening and leads to a refill seal which serves for abutment of a stem of a donor liquid container. 
     
     
         13 . A refill system according to  claim 12 , wherein the sealing structure closes in its first position and opens in its second position a ventilation opening. 
     
     
         14 . A refill system according to  claim 13 , wherein the ventilation opening is provided on the wall with the refill opening. 
     
     
         15 . A refill system according to  claim 1 , wherein the sealing structure comprises a container seal with at least one clearance hole, preferably two clearance holes, more preferably three clearance holes, wherein the container seal is biased against the wall with the refill opening from the container structure by means of at least one elastic element such that the container seal is in liquid-tight contact with the wall. 
     
     
         16 . A refill system according to  claim 1 , wherein the sealing structure is held in its first position by form fit of a locking element with the container structure so that a movement of the sealing structure along the wall with the refill opening is prevented. 
     
     
         17 . A refill system according to  claim 1 , wherein the sealing structure is biased from the inside of the container structure in a direction along the wall with the refill opening by means of a releasing elastic element. 
     
     
         18 . A refill system according to  claim 1 , wherein the sealing structure closes in its first position and opens in its second position a ventilation opening. 
     
     
         19 . A refill system according to  claim 4 , wherein the sealing structure comprises a container seal with at least one clearance hole, preferably two clearance holes, more preferably three clearance holes, wherein the container seal is biased against the wall with the refill opening from the container structure by means of at least one elastic element such that the container seal is in liquid-tight contact with the wall. 
     
     
         20 . In combination, a refill system and a perfume bottle configured for use with the refill system, the refill system comprising a container structure, having a wall with a refill opening, and a sealing structure, wherein the sealing structure is held by the container structure movably along the wall with the refill opening and is movable between a first position, which closes the refill opening, and a second position, which opens the refill opening.
