Description

[0045] The invention is explained with reference to figures. In the figures:

[0046] FIG. 1: shows a perspective view of a container closure;

[0047] FIG. 2: shows a refill container;

[0048] FIG. 3: shows a closure lid;

[0049] FIG. 4: shows a plug;

[0050] FIG. 5: shows a container closure and a plug in engagement with one another;

[0051] FIG. 6: shows a container closure with the plug removed;

[0052] FIG. 7: shows a refill container in engagement with a refill opening on a container closure.

[0053] For the sake of clarity, a container on which the container closure is arranged is not shown in the figures.

[0054] FIG. 1 shows a perspective view of a container closure 100. The container closure 100 has a base body 20. A discharge opening 21 and a refill opening 22 are arranged in the base body 20. The refill opening 22 is closed with a plug 30. Two position marks 23 and 24 are arranged in the area of the refill opening 22, with which a corresponding position mark 32 of the plug 30 can be brought into alignment.

[0055] The container closure 100 is designed as a flip-top closure and has a flip-top lid 101 on which a closure plug 102 is arranged. The closure plug 102 closes the discharge opening 21 when the flip-top lid 101 is actuated. It also covers the plug 30.

[0056] FIG. 2 shows a refill container 300. Said refill container has a filler neck 40, which is closed with a closure 50. The refill container 300 is designed as a bag.

[0057] FIG. 3 shows a closure lid 50 in a perspective representation. The closure 50 has an unspecified structure on its periphery in order to be able to grip the closure 50 securely. At one end, the closure 50 has a recess in which a drive contour 51 is arranged. The drive contour 51 rises from the bottom of the recess as a positive protrusion. In the present case, the drive contour is designed with five radially extending protrusions and is therefore star-shaped.

[0058] FIG. 4 shows a plug 30 in a perspective representation. The plug 30 has an unspecified thread as a fastening means for fastening in the refill opening 22 (see FIG. 1 or 6). At one end, the plug has a recess as driving contour 31. In the present case, the driving contour 31 is designed to complement the drive contour 51 (see FIG. 3). In the present case, the drive contour is designed with five radially extending recesses. A position mark 32 is also arranged on the plug 30, which in the present case is designed as a radially extending protrusion.

[0059] FIG. 5 shows a container closure 100 and a plug 30 in engagement with one another. For this purpose, the drive contour 51 and the driving contour 31 are brought into engagement with one another. It can be seen that at this point in time, i.e. when the refill opening 22 is still closed, the position mark 32 and the position mark 23 are adjacent to one another. Typically, the closure 50 is unscrewed from the refill container 300 to create the state shown in FIG. 5.

[0060] FIG. 6 shows a container closure with the plug 30 removed. For this purpose, the closure 50 was rotated counterclockwise together with the plug 30 (FIG. 5) until the position mark 32 comes to lie adjacent to the position mark 33. The plug 30 can then be removed. As can be seen, the refill opening 22 is free.

[0061] FIG. 7 shows a refill container in engagement with a refill opening 22 on a container closure 100. A refill nozzle 40 is arranged on the refill container 300, which has fastening means corresponding to fastening means on the refill opening 22. In the present case, these are interlocking threads. This enables the secure connection of the refill container to the container on which the container closure 100 is arranged.

[0062] During the refilling process, the air can escape from the container through the discharge opening 21.

[0063] The thread on the filler neck is the same thread as that on the plug 30 (see FIG. 4). Accordingly, an internal thread on the closure 50 (see FIG. 3) is also designed in the same way as the thread of the refill opening.
