A liquid blow molding method of molding a liquid container containing a content liquid from a preform, includes a nozzle engagement step of engaging a blow nozzle with a mouth portion of the preform; a molding step of molding the preform into a container of a predetermined shape by supplying a pressurized liquid into the preform; a suck-back step of sucking back a predetermined amount of liquid from the inside of the container to a supply channel by operating a pump in a reverse direction with the container put in the upside-down posture while the blow nozzle is engaged with the mouth portion; and a nozzle separation step of separating the blow nozzle from the mouth portion with the container put in the upright posture.

To reduce an amount of use of a replacement gas used for replacing air in a container. A gas replacement system includes: a washing machine that washes the container with water; a filling machine that fills the container with a content fluid; a sealing machine that seals the container transferred from the filling machine; a chamber that covers the filling machine and the sealing machine, and contains a replacement gas; and a water discharge mechanism (washing machine) that discharges the water in the container having been carried into the chamber while containing the water out of the container in the chamber. The water in the container is replaced with an ambient gas in the chamber along with the discharge of the water.

The invention relates to a closing device for closing containers which have a filling opening, such as bottles or cans, comprising a positioning apparatus for arrangement of a container to be closed into a position for closing, a flushing apparatus with a nozzle device for blowing in flushing gas, in particular inert gas, into a container to be closed though its filling opening prior to closure, a closing element setting apparatus for attachment of a closing element to a container to be closed in a position which closes its filling opening and thus the container and a control apparatus.

The invention relates to a method (100) for preserving a foodstuff in a hydrogen atmosphere in a packaging (200) comprising an interior space (220) enclosed by a hydrogen-permeable and airtightly sealable casing (210), the interior space (220) comprising a foodstuff space (221) for receiving the foodstuff and a hydrogen space (222) for receiving hydrogen gas, the foodstuff space (221) and the hydrogen space (222) being at least gas-conductively connected to one another, and the casing (210) or a sleeve (230) surrounding the hydrogen space (222) being dimensionally stable at a negative pressure in the hydrogen space (222) relative to an environment of the packaging (200) of at least 100 mbar. The method comprises at least the following steps: filling (110) the foodstuff at least into the foodstuff space (221), introducing (120) hydrogen gas at least into the hydrogen space (222), airtightly sealing (130) the casing (210) after the filling (110) and introduction (120), and generating (140) a negative pressure at least in the hydrogen space (222) relative to an environment of the packaging (200). The invention further relates to a packaging for use in a method according to the invention and to such use.

A liquid blow molding method of molding a synthetic resin preform having a mouth portion into a liquid container of a predetermined shape, including: an air-liquid replacement step of supplying a liquid into the preform from the mouth portion through a blow nozzle and discharging the air inside the preform to the outside; an air-liquid separation step of separating the air from the liquid inside the preform by vibrating the preform; and a blow molding step of molding the preform into a container of a predetermined shape by supplying a pressurized liquid into the preform from the mouth portion through the blow nozzle, after the air-liquid separation step.

The present specification discloses a method of protecting an inner wall surface of a vessel from damaging interaction with an additive added to the vessel, where the method includes providing the vessel at least part way filled with a liquid product; applying a force on the vessel the force being configured to create a change in shape of a surface of the liquid product; and providing sufficient containment of the additive by the change in shape of the surface of the liquid product to substantially prevent damaging interaction between the inner wall surface of the vessel and the additive for at least an additive reaction time period at the end of which the additive is rendered substantially incapable of producing damaging interaction to the inner wall surface of the vessel.

A container-treatment machine includes a foaming unit that introduces foaming medium into a container that is filled with a foamable liquid. This causes a foam to form in the container. A sensor downstream obtains an image of the foam and provides it to a controller. The controller decides whether or not to eject the container based on the extent of a foam nose that forms on the container's outer surface.

A device for transporting a filled container in a rotary device, for example from a rotary filler to a capper, includes a rotary element rotating about an axis of rotation with a holding element for accommodating the container. The holding element is designed such that the filled container is held so that a container axis, which passes through and is perpendicular to a mouth aperture cross-sectional plane of the container, is oriented below the holding element toward the axis of rotation.

A liquid blow molding method of molding a liquid container containing a content liquid from a preform, includes a nozzle engagement step of engaging a blow nozzle with a mouth portion of the preform; a molding step of molding the preform into a container of a predetermined shape by supplying a pressurized liquid into the preform; a suck-back step of sucking back a predetermined amount of liquid from the inside of the container to a supply channel by operating a pump in a reverse direction with the container put in the upside-down posture while the blow nozzle is engaged with the mouth portion; and a nozzle separation step of separating the blow nozzle from the mouth portion with the container put in the upright posture.

Various embodiments relate to devices and methods for treating a mixture of expansion gas and filling product foam in a beverage filling plant, comprising the steps of introducing the mixture of expansion gas and filling product foam into a closed separation container and extracting the expansion gas out of the closed separation container via suction.
