Apparatus for forming hollow containers (110), suitable to contain in particular one or more liquid or semi-liquid food products, starting from parisons (F) made of thermoplastic material. The apparatus comprises a matrix (11) defined by a pair of molds (12) cooperating with each other to define a cavity (13) shaped like the container (110) to be formed, and to define a support channel (14), configured to define an additional portion (112) of said container (110). The apparatus also comprises a forming punch (17), operatively mobile through said support channel (14) to enter into/exit from said cavity (13) so as to thrust and blow one of said parisons (F) against the walls of said cavity (13) to form at least said container (110).

ABSTRACT The invention provides a method for leakage detection in a device for shaping container preforms, comprising a compressed air system which is connected to a compressed air source and comprises at least two fluidically connected regions that can be separated from each other and/or from the environment by shut-off elements. The method comprises a leakage test run conducted in an automated manner in which at least one of the blocking elements and/or the compressed air supply into the compressed air system is controlled in such a way that it can be determined separately for each region whether compressed air escapes therefrom.

A device for capping a container with a container cap, for example in a beverage filling plant, includes an isolator for providing a defined atmosphere in the interior thereof; a capper for capping a container with a container cap, which capper is arranged in the isolator; and a cap production device for producing container caps from a hot melt, for example a plastics melt. The cap production device is arranged outside the isolator, and is interconnected with the isolator or is connected to the isolator via a cap transport tunnel in order to feed produced container caps to the capper.

Apparatus (1) for treating plastic preforms (10) with a preform sorting device (2) comprising a sorting device (3) and a damming device (5) which transports the plastic preforms (10) along a first rectilinear transport path (T1), wherein the sorting device (3) is suitable and intended to bring the plastic preforms (10) into a predetermined orientation and the damming device (5) is suitable and intended to feed the plastic preforms (10) in an ordered manner to a heating device (12) arranged downstream of the preform sorting device (2), which heats the plastic preforms (10) to a temperature necessary for blow moulding, wherein the heating device (12) transports the plastic preforms (10) along a substantially second rectilinear transport path (T2) and a plurality of stationary arranged heating elements (14) are arranged along the second rectilinear transport path (T2). According to the invention, the preforms sorting device (2) and the heating device (12) are arranged on a common carrier (9).

A preform is sterilized by a preform sterilizer. The preform is blow-molded by a blow-molding device to manufacture a container. Next, the container is filled with a culture medium by a filling device without sterilizing the container by a container sterilizer, and the container is plugged by a plugging device. Thereafter, it is verified how much microorganism survive or propagate in the culture medium in the container. A degree of sterilization in the container sterilizer is adjusted on the basis of a verification result.

Apparatus for treating plastic preforms, having a transport device which transports the plastic preforms along a predetermined transport path, having a first application device which loads the plastic preforms with a first flowable medium through their mouth during their transport along a first transport path section,

wherein
the apparatus has a second application device which acts upon the plastic preforms with a second flowable medium during their transport along a second transport path section through their mouth.

Method for operating an apparatus for producing plastic preforms and plastic containers, comprising at least one injection moulding machine and one blow moulding machine, wherein the plastic preforms are injection moulded within the injection moulding machine and are formed into plastic containers within the blow moulding machine and are transported from the injection moulding machine to the blow moulding machine, wherein a heating device is arranged downstream of the injection moulding machine and the injection moulding machine and the blow moulding machine are coupled to one another. According to the invention, the plastic preforms produced in the injection moulding machine are transferred directly after production to a thermal preform storage, which holds the plastic preforms at a predetermined temperature and wherein a speed and/or at least one parameter of at least one subsequent treatment device can be changed.

To facilitate removal of foreign matters from a preform. The preform in an inverted position with a mouth portion thereof facing down is being continuously transferred, filtered air is blasted into the preform through the mouth portion of the preform, and at the same time, air is sucked from the side of the mouth portion of the preform. Foreign matters can be more easily discharged from the preform because of the flow of air and the weight of the foreign matters.

An apparatus for shaping plastic preforms into plastic containers is disclosed. Said apparatus comprises a conveying device on which a plurality of blowing stations are arranged. Each of said blowing stations encompasses a blow mold, within which a plastic preform can be shaped into a plastic container. The apparatus further comprises a clean chamber, within which the plastic preforms can be conveyed. According to the invention, the zone of the conveying device in which the blowing stations are arranged is located in the clean chamber, and at least one additional zone of the conveying device is located outside the clean chamber.

A heating apparatus and heating method for preforms that heat a sterilized preform to a temperature at which the preform can be molded into a bottle in an aseptic atmosphere. Additionally, an aseptic blow molding machine and an aseptic blow molding method that can mold the sterilized preform into a bottle in the aseptic atmosphere, and can take out the bottle from a bottle molding machine in a state where the sterility of the bottle is maintained. A chamber covering a heating unit that heats the preform is provided, and a sterilizing apparatus that sterilizes the inside of the chamber, and an aseptic air supplying apparatus for maintaining the sterility are provided. Additionally, a chamber covering a molding unit that molds the preform into a bottle is provided, a sterilizing apparatus that sterilizes the inside of the chamber, and an aseptic air supplying apparatus for maintaining the sterility are provided.
