FIELD: packaging.

SUBSTANCE: invention relates to prefabricated bottles and, in particular, to a prefabricated bottle including a container, a pacifier, a cuff for attachment of the pacifier to the container, and a lid for closing of the pacifier, when the container is not used. Prefabricated bottle (100) contains: container (102) having open end (110), closed end (108), main part (114), and neck (116), together forming chamber (106) for liquid inside container (102), wherein the neck has rim (118) forming the open end of the container, while container (102) has a central axis; ventilation unit (180) made with the possibility of being at least partially located on rim (118) of the container to provide ventilation of the container during use, wherein the ventilation unit contains at least one side ventilation hole (234) passing not parallel to the central axis of the container, when the ventilation unit is located on rim (118) of the container, wherein the ventilation unit contains ventilation insert (182) including at least one side ventilation hole and perimeter wall (240), wherein the perimeter wall forms at least one ventilation opening (249) and at least partially forms annular gap (252) passing in a circumferential direction around the ventilation insert, while the perimeter wall includes a bent surface forming the specified annular gap, wherein the bent surface is concave relatively to an outer part of the ventilation unit, while at least one ventilation opening communicates via fluid with at least one side ventilation hole and the annular gap in such a way that air can flow from the annular gap to the side ventilation hole through the ventilation opening; and cuff unit (104) essentially forming a capping means for the container, wherein the cuff unit is made with the possibility of released engagement with the neck of the container over its open end to hold the ventilation unit together with the container, while, between the cuff unit and the ventilation unit, the annular gap is formed.

EFFECT: invention provides an improved air flow into a prefabricated bottle during use and prevents leakage.
