Non drip baby feeding bottle, includes two apertured twist fit closure rings for controlling flow of contents from bottle and into teat

摘要

Bottle has hole (48) extending through support surface of cylindrical mantle of upper closure ring (40) to exit in external threading region of mantle. Hole (31) extends through support surface of cylindrical mantle of lower closure ring (20). Holes are exposed or blocked by twisting upper closure ring relative to second closure ring. The bottle (10) has an opening (15) with external threading (14), a lower closure ring (20), an upper closure ring (40), catch components (34, 54) for releasably and rotatably fixing the two rings together, a teat (60), and a screw ring (70) with internal threading. The lower closure ring comprises a cylindrical first mantle with internal threading for screwing onto the external threading of the bottle. A middle part joins the top side of the first mantle and has a rotation symmetrical support surface separated from the inside of the bottle. At least one hole (31) extends through the support surface and into the inside of the bottle. The upper closure ring comprises a cylindrical mantle with external threading. A middle part joins the top side of the second mantle and has a rotation symmetrical support surface that sits tightly on top of the lower closure ring support surface. At least one hole (48) extends through the upper closure ring support surface to exit in the external threading region of the upper closure ring mantle. These holes are exposed or blocked by twisting the upper closure ring relative to the lower closure ring. The screw ring is screwed onto the external threading of the upper closure ring, to which a bottom edge region of the teat is releasably secured.
