Abstract

Prior-art rubber hot-water bottles have a screw cap, which is arranged directly on the bottle body and forms a rather hard thickening there, which is felt to be irritating when the user is lying on the bottle. Moreover, a screw cap is difficult to use and must be screwed in with a certain force, which also requires corresponding forces for loosening. To avoid these drawbacks, it is proposed according to the present invention that a clamping means (23, 40), by which the bottle neck can be closed, be provided on the bottle neck (21) of the rubber hot-water bottle. Clamping means are simple to use and require only little force for closing. In addition, they can be opened easily and are very flat, so that they are not irritating. Furthermore, the bottle neck (21) may be designed such that the clamping means (23, 40) can be led away from the body of the user.
