Method for producing a plastic bottle, and preform and blowing mold suited therefore are disclosed. An exemplary process can produce a plastic bottle, for example, a PET bottle. Such a bottle can be produced from a preform which has a body which is closed on one side, which is connected to a neck section with a pour opening, in which the preform which has been produced in a plastic injection process or an extrusion process is placed in the mold cavity of a blow mold and inflated using the blow nozzle by overpressure according to the mold cavity. Sealing can take place between the blow nozzle and the preform within the preform.

A safety rotating closure for a multi-compartment bottle including a two-chamber bottle with a separate pour neck with a pour opening for each chamber and a rotating closure which can be screwed onto a common neck part of the multi-compartment bottle and is provided with a mechanically acting child safety device against unauthorized loosening of the rotating closure. The rotating safety closure has essentially conical seal parts which in the screwed-on state engage the pour openings of the pour necks and interact with the inside walls to form a seal. The interlocking elements of the child safety device are located on the rotating safety closure.

Blow molding tool arrangement is disclosed for an extrusion blow molding machine for plastic containers, especially for plastic bottles, comprising two or more blow mold parts (1, 2) which can be moved from an open into a closed position and vice versa and in the closed state border a mold cavity (7) which has at least one access opening (22) for a blow mandrel (8), and with at least one laterally movable ejection device (10) for removing from the mold a plastic tube which has been inflated by overpressure according to the mold cavity (7). The ejection device (10) is arranged such that it can be extended laterally relative to the inside wall of the mold during ejection and touches the plastic tubing upon ejection in a lost section (74) which is detached after removal from the mold.

A plastic container for a roll-on deodorant is described, which roll-on deodorant has a receptacle and a roll cage for the captive, rotatable holding of an applicator ball. The roll cage can be made integral with the receptacle. The plastic container can be produced in an extrusion-blow-molding method from a tube that is for example extruded continuously.
摘要:
An extrusion blow-molding method for plastic containers, for example, plastic bottles, is disclosed, wherein a one- or multi-layer plastic tube is extruded with a predetermined extrusion pressure through an annular gap, which is delimited by an extrusion die provided on an extrusion head and a axially adjustable mandrel and which can be adjusted with regard to the width thereof. The extruded plastic tube is introduced into a mold cavity of a blow-molding tool arrangement, blow-molded into a plastic container in accordance with the mold cavity by overpressure and then demolded. Additional plastic material is added in metered quantity to the extruded plastic tube at least in some regions in the direct vicinity of the mouth of the extrusion die. The additional plastic material is introduced through one or more discharge nozzles distributed across the circumference with a pressure that is higher than the extrusion pressure such that the plastic material is locally compressed and that, after passing the extrusion die, the plastic tube in the regions provided with the additional plastic material has a greater wall thickness than the remaining plastic tube.
