Device for arresting a bottle against an applied torque
The device for holding in an axial direction a pouring neck of a bottle having a radially projecting neck ring and for arresting the pouring neck against a torque applied to the pouring neck in one of two rotary directions upon rotation about the axis of the pouring neck has a carrier ( 1 ) which is open at one side and which partially embraces the pouring neck and which has a U-shaped opening ( 2 ) with an arcuate bottom ( 3 ) whose central axis is perpendicular to the carrier ( 1 ), and also has a projecting engagement portion ( 9 ) for arresting against rotary movements. To improve such a device so that the pouring nick which is to be arrested can be more easily introduced into the carrier and removed therefrom again, even when a plurality of pouring necks is being simultaneously loaded and unloaded, wherein the device is simple to produce without involving high cost and preferably involves less wear, the invention provides that the projecting arresting engagement portion( 9 ) is arranged in the direction of the central axis at the level of the arcuate bottom ( 3 ) of the carrier ( 1 ) on the extended arc( 3 a ) of the bottom ( 3 ) displaced in relation thereto in the region of the open side of the bottom ( 3 ) and a counterpart support ( 12 ) is provided on the other side approximately on the extended arc ( 3 a ) in opposite relationship to the engagement portion ( 9 ).
