Abstract

Refill system (1) of a liquid container (3), wherein a conduit element (5) is fixed to the liquid container and has an upper part flow passage (9) 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 (11) into a space (13) defined by the conduit element and the wall of the container, and wherein, in its first position, a closing element (31) having a first sealing portion (35) is capable of sealing the space liquid-tightly towards the outside.

Refill System of a liquid container


The enclosed embodiments 1 and 2 show a refill system 1 of a liquid container 3, in this case a flacon, with a conduit element 5 capable of communicating the inside with the outside of the liquid container 3 and being liquid-tightly connected to the liquid container 3, and a closing element (310), which element has hollow cylinder elements 311 and 312, i.e. adjustment ring and pole, capable of being in a first position (Fig. 2) which prevents a liquid flow through the conduit element 5 and a second position (Fig. 1) which allows a liquid flow through the conduit element 5, wherein the conduit element 5 is fixedly connected to the liquid container 3 and has an upper part with an upper part flow passage 9 having one end inside the liquid container 3 and the other end leading past the liquid-tight connection of the conduit element 5 with the liquid container 3 and subsequently through at least one upper part radial opening 11 into a space 13 defined by the conduit element 5 and the wall of the liquid container 3, in its first position, the closing element 310 having a first sealing portion 35 is capable of sealing the space 13 defined by the conduit element 5 and the wall of the liquid container 3 liquid-tightly towards the outside.

In the first position of the closing element 310, the first sealing portion 35 of an inner step 33 seals the space 13 defined between the conduit element 5 and the wall of the liquid container 3 between lower part radial openings 17 and the upper part radial openings 11, thereby blocking and preventing any liquid flow through the conduit element 5 either from the outside towards the inside or vice versa. Further, a second sealing portion 41 of an intermediate step 39 seals together with the first sealing portion 35 an ventilation passage 7, thereby blocking any fluid flow through the ventilation passage 7.

In the second position of the closing element 310, the first sealing portion 35 of the inner step 33 seals the space 13 defined between the conduit element 5 and the wall of the liquid container 3 below the lower part radial openings 17 in a direction away from the liquid container 3, thereby allowing liquid flow through the conduit element 5 either from the outside towards the inside or vice versa. Further, the second sealing portion 41 of the intermediate step 39 is distant from the wall of the liquid container 3, thereby allowing fluid flow through the ventilation passage 7. So, even in its second position, the closing element 310 seals the ventilation passage 7 from the flow passage 9,15 by means of the f...
