A packaging machine includes a pair of grips holding vicinities of two sides of a bag mouth of a packaging bag, a moving body to intermittently moving the paired grips every one of a plurality of packaging steps, and a paper packaging bag sealing device provided in a section where a sealing step is carried out, for sealing a paper packaging bag to which a sealing adhesive agent has been applied.

This invention relates generally to the distribution of a flushing gas during a packaging process. More specifically, the invention relates to a system and method for cooling and distributing a flushing gas during such a process that utilizes the gas' lower temperature and increased density to both maintain the flushing gases' placement within a packaging container and displace any undesirable gases there-from.

One embodiment of the present invention provides a system for processing containers. The system may include an apparatus for processing sealed plastic containers having a first headspace pressure. The apparatus may include: an open entry port or tunnel for continuously receiving containers; a sanitizer configured to sanitize outside surfaces of the received containers; a perforator configured to perforate or open a cap or seal of the containers within the apparatus; a sealer configured to seal the perforation or opening formed in the cap or seal of the containers; an open exit port or tunnel for continuously exiting the processed containers; and a conveyor system configured to transport or convey the containers. The system may further include a production line including a filler for filling empty blow-moulded containers with a heated liquid to pasteurize inside surfaces of the containers and a capper for sealing the filled blow moulded containers.

The present document presents a system and a method for packaging powders in containers (S) through a hopper (T) and a first tube (TC) connected to the hopper (T). Air is sucked both in the area of the first tube and in the area of the hopper. The powder is then drawn directly from inside the hopper thus keeping the flow rate and the degree of compacting of the system constant. Moreover, the powder sucked inside the first tube is thus compacted and can be conveyed compacted towards the outlet. In this way it is possible to control the dosing of the product exiting from the system with high precision.

Process to produce containers out of preforms, in which the preform is inserted in a form-filling station, molded and filled in this station. Gas, which remains in the head space after the end of the filling process, is replaced by a purge gas, and a form-filling machine is provided to produce and to fill containers made of preforms.

A system for evacuating and sealing containers filled with product, for example, food product, includes an enclosed, sealed housing wherein the pressure level and the atmospheric content can be controlled. A vacuum shroud is positioned in registry with a container entrance opening in the housing, the shroud connectible to a vacuum source and to a source of replaceable gas to replace the ambient air to be removed from the container. The shroud is advanceable to seal the container entrance opening and is retractable from the container entrance opening. A container transport system inserts the container through the housing entrance opening and into the shroud. Thereupon, a sealing system seals the housing from the ambient after the container has been inserted into the shroud. After the air in the container has been replaced with an inert gas and then the shroud retracted, a closure subsystem applies a cover to the evacuated container. Thereafter, an out feed subsystem removes the closed container from the housing while maintaining the atmospheric content and pressure level within the housing.

The present invention discloses a bag packing mechanism for mushroom cultivation, which comprises two clamping seats, transport means, air duct, pumping means and push rod. Transport means supply collar. Air duct descends through the collar and extends into a bag from the opening of the bag, the two clamping seats clamp the top portion of the bag to close to the outer periphery of the air duct, the pumping means sucks the top portion, the two clamping seats open, the push rod is lowered to push down the collar to put on the top portion, the pumping means blow to open the top portion, the push rod is further lowered to fold the top portion down, the air duct and putter rise, and then complete the automation of packaging job.

One embodiment of the present invention provides an apparatus for processing sealed plastic containers having a first headspace pressure. The apparatus may include: an open entry port or tunnel for continuously receiving containers; a sanitizer configured to sanitize outside surfaces of the received containers; a perforator configured to perforate or open a cap or seal of the containers within the apparatus; a sealer configured to seal the perforation or opening formed in the cap or seal of the containers; an open exit port of tunnel for continuously exiting the processed containers; and a conveyor system configured to transporting or convey the containers from the open entry port or tunnel, through and within the apparatus, to the open exit port or tunnel and away from the sanitized environment of the apparatus. The apparatus may be further configured to maintain a sanitized environment within the apparatus, perforator, and/or sealer.

A liquid filling apparatus has a vertical tube with bottom opening opened and closed by a valve. The tube is insertable into a container from above and supplies liquid to the container. A flexible separating disk extends radially from the bottom end of the tube. The tube with flexible separating disk is movable toward the container bottom and air in the container escapes between peripheral rim of the separating disk and container wall as the tube moves down until the flexible separating disk rests on the container bottom. The tube with flexible separating disk then is moved upwardly so that, between flexible separating disk and container bottom, an enlarging space is formed with upward movement. Liquid is supplied into this space through the open tube opening as upward movement continues. When a targeted liquid level is reached, the valve closes and the tube is pulled from the container.

A dispenser for holding multiple doses of fluids or other substances, and for dispensing the substances, has a vial, a flexible bladder received within the vial, and a variable volume storage chamber formed between the bladder and vial. A filling valve is coupled in fluid communication with the storage chamber and defines (1) a normally closed, fluid-tight position hermetically sealing the storage chamber from the ambient atmosphere, and (2) an open position allowing the passage of fluid through the valve both to evacuate the storage chamber and to introduce fluid through the valve to fill the storage chamber. A pump is coupled in fluid communication with the storage chamber for pumping fluids out of the storage chamber. A dispensing valve is coupled in fluid communication with the pump and defines (1) a normally closed, fluid-tight position preventing the passage of fluid out of the dispenser, and (2) an open position for dispensing pumped fluid therethrough. The sealed, empty dispenser is sterilized, such as by applying gamma radiation thereto. Then, the sterilized, sealed, empty dispenser is filled with fluid by engaging the filling valve with an evacuating/dispensing member to evacuate the storage chamber, and by introducing fluid from the filling member through the open filling valve and into the storage chamber. The filling member is withdrawn from the valve, and a spring moves the valve to a closed position to hermetically seal the fluid within the dispenser.
