A flexible package including a package body including a first side-surface film and a second side-surface film sealed in a peripheral portion. The package body has sealed portions formed in side edge portions such that a non-sealed portion is formed in at least one of the sealed portions. The non-sealed portion has a gas injection portion containing a gas which has a specific heat at constant volume of 0.67 kJ/kg.Math.deg or higher at 0 C. and 1 atm. The gas injection portion has a diameter of from 3 to 50 mm and is formed such that a repelling force is from 4 to 30 N at 23 C. and 1 atm when an entire gas injection portion is nipped from both sides of the first and second side-surface films and squeezed until a nipped gas injection portion has a width equal to a half of the diameter of the gas injection portion.

A machine and method for the application of pressure relief valves for hermetic containers. The machine comprising an applicator configured to apply the valves to containers, a vibrating feed container for housing the valves and making the valves directly available to the applicator, an aspirator configured so as to suck the valves contained within a reservoir and convey them to the vibrating feed container through a tube. The method comprises supplying pressure relief valves to the vibrating feed container of the machine by sucking the valves from the reservoir.

An automatic machine includes: a central frame; a support rotatably connected to the central frame; handling mechanisms for moving the support; a plurality of carriages supported by the support; each carriage supports a bag vertically; a loading station; a spreading station downstream of the loading station; a filling station downstream of the spreading station; a first heat-sealing station downstream of the filling station; an insertion unit that loads a straw in the bag; a second heat-sealing station. The insertion unit is provided in the first heat-sealing station.

A system and method for producing a medical bag with an HF welder that uses upper and lower dies each having a plurality of electrode lamellae arranged such that they are alternatingly polarized relative to adjacent lamellae and opposing lamellae. Interspersed dielectric materials may be used to impart contours onto the film material to produce a patterned bag.

A spout holding device for holding a spout part having a communication hole, includes an elastic part capable of elastically deforming in a direction orthogonal to a first direction when compressive force or tensile force is applied to the elastic part in the first direction, wherein the elastic part applies elastic force to the spout part in three or more different directions orthogonal to the first direction to hold the spout part.

A production machine for the production of collapsible pouches having a fitment. The machine has a fitment sealing station with an impulse sealing device comprising a first jaw and a second jaw and with an actuator device configured to move the first and second jaws relative to one another between an opened position and a clamped position, as well as a cooling device configured to cool each of the first and second jaws. The fitment sealing station is configured to perform an impulse sealing cycle.

A method and device for opening spout attachment portion of a bag being set up such that films on both sides of a spout attachment portion (2) of a bag (1) are suction-held up by a pair of suction cups (8), and the spacing between the pair of suction cups is widened to open the spout attachment portion, after which a gas is blown from the spout attachment portion into the bag by a gas blowing member (9); and when the gas is blown into, a clamping member (19) clamps a position under the gripper that is on the top edge (6) side of the bag from both sides of the bag, thus suppressing outflow of the gas blown into the bag from the top edge, thus allowing entire bag to inflate for its entirety substantially and the spout attachment portion to be kept opened.

A process for producing a flexible container is provided. The process includes: A. providing a rear panel web, a front panel web, a first folded gusset panel web, and a second folded gusset panel web, each panel web having peripheral edges and a bottom face, each bottom face having two opposing tapered edges meeting at a bottom end; B. placing the folded gusset panel webs between the rear panel web and the front panel web, the gusset panel webs opposing each other, the panel webs configured to form a common periphery and the bottom seal area including the bottom end of each panel; C. first sealing the peripheral edges, the tapered edges, and the bottom seal area under a set of heat seal conditions; D. second sealing a portion of the bottom seal area under a second heat seal condition; and E. forming a flexible container.

A packaging container with a pull tab is provided. The packaging container includes a pouch with at least one opening or at least one perforated openable area in a pouch wall, and one or more pull tab labels adhesively connected to at least one outside wall of the pouch and covering the at least one opening or one perforated openable area. The one or more pull tab labels include a substrate with at least one notch in an edge of the pull tab label and a pressure sensitive adhesive on at least a portion of one surface of the substrate. The peel strength between the pull tab label and the outside wall of the pouch is lower in the area of the pull tab label proximate the notch then in the area of the pull tab label proximate the opening or the perforated openable area in the pouch.

Provided is a pouch container aligned structure, wherein: each pouch container has a folded body part that is the top end of one of a pair of body sheets folded into a substantial V shape, with one end of a top sheet also forming the folded body part by being joined to the top end of the body sheet and the other end of the top sheet forming the distal end portion of the container by being joined to the top end of the other of the pair of body sheets; and the pouch containers are aligned in a state in which the distal end portion of one pouch container is inserted into the folded body part of another pouch container.
