The invention relates to a plastic container () comprising a blow-molded container part for receiving a filling product, comprising a container body and a container neck, wherein the container neck () comprises an inner wall () and an outer wall (), a pouring element () that can be mounted on the container neck () and comprises a pouring opening (), and a closure () by means of which the plastic container () can be closed. A first and second holding means () are formed on the inner wall () of the container neck (), wherein the first holding means () is formed so as to hold the pouring element () in the container neck () and the second holding means () is formed so as to hold the closure () in the container neck ().

Plastic container comprising a pouring element

The invention relates to a blow molding tool for a blow molding machine for producing plastic containers in an extrusion or stretch blow-molding process. The blow molding tool comprises two blow mold halves, each of which comprises at least one molding body in which at least one mold cavity is disposed, and a baseplate that receives said molding body. An insulation block consisting of a thermally insulating material is arranged between the molding body and the baseplate and, optionally, further components of the blow mold halves.

Blow molding tool for a blow molding machine

A method for transferring a negative structure of a surface of an inner wall () of a blow molding tool () onto a surface of a plastic container. The method comprises the steps of heating at least one region () of a mold cavity () of a molding body () of the blow molding tool (), on which the negative structure is formed, inserting a preform into the mold cavity (), closing the blow molding tool (), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall () of the mold cavity (), cooling the region () by supplying a coolant through temperature control channels (), and removing the plastic container from the mold.

The invention relates to a plastic container having a container wall delimiting an interior of the container, and an outlet on the container wall for pouring out a product contained in the plastic container. A recess that projects into the interior of the container and is provided for accepting a functional element is formed on the container wall, with the recess being accessible through an insertion hole.

The invention proceeds from a tube produced from a plastics material, having a tube body, which has a first end and a second end, having a tube head, which is connected to the tube body at the first end and has a removal opening, and having a tube fold which is formed at the second end and has a first sealing surface and a second sealing surface, wherein the first and the second sealing surfaces are connected to one another in a fluid-tight manner. According to the invention, the sealing surfaces have arranged between them a retaining insert, which is connected to the first sealing surface and the second sealing surface in a fluid-tight manner.

Plastic tube

The invention relates to an extrusion blow molded tube, which is filled or can be filled by way of its rear end, and the body, shoulder and neck of which are produced in one piece by extrusion blow molding. The tube has an LLDPE-rich layer with an LLDPE content of 50 to 95% by weight, and the average wall thickness of the tube in the region of the body is 0.3 to 0.85 millimeters.

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.

Method for producing a plastic bottle, and preform and blowing mold suited therefor

A method is disclosed for providing dimensional accuracy of a pour opening in or on a plastic container produced by extrusion-blow-molding. The method can include inserting a section of a plastic hose, extruded in one or more layers through an extrusion nozzle, into a mold cavity of a blow mold tool; and inflating the plastic hose by a calibrating blow pin according to a shape of the mold cavity, whereby at least one pour opening of the plastic container is determined with respect to its inside diameter and its inside contour to form a completed inflated plastic container, and wherein the calibrating blow pin is axially inserted into the plastic hose section after a head plate of the blow mold tool has been closed.

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.

Plastic container for a roll-on deodorant

The present invention relates to a process for blowing an article with at least one recess.

Process for the manufacture of an article comprising a recess

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.

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.
