<p>A bottleneck collar relates to the structural features of a bottle and can be used in the food industry for packing, storing and transporting various alcoholic and non-alcoholic beverages in bottles. The solution to the problem of producing a bottleneck collar provides for the technical result, when said collar is used in bottles, of increasing the operational characteristics of said bottles. The above-mentioned problem is solved by the bottleneck collar being equipped below the screw cap with a nozzle which is formed integrally with a threaded part and is arranged thereabove, wherein the height of the nozzle is not less than 1/2 the height of the collar. Furthermore, the external surface of the nozzle is made either with a narrowing, or with an expansion of the nozzle upwards, or also with an expansion of the upper part of the nozzle upwards. Furthermore, the internal surface of the nozzle in the upper part is in the form of an inverted cone, or in the form of an inverted cone that passes into a downwardly expanding conical surface of the nozzle.</p> |
