A hermetically sealed enclosure for use in fabricating a polymeric dental article. Monomers are mixed within the enclosure by squeezing a first burst pouch to break a first burst seal between it and a second burst pouch and manipulating the enclosure by hand to initiate a polymerization reaction while the enclosure remains hermetically sealed. A second burst seal between the second burst pouch and a dispensing funnel chamber is broken by further squeezing which forces the mixture into the dispensing funnel chamber. The mixture is dispensed from an outlet of the dispensing funnel chamber by further squeezing after a tear-off strip closing the outlet has been torn off.

An automatic packaging machine for paper bags contains: a support platform, a rotation table, a stacking device, a displacement device, a packaging device, and a paper delivery device. The support platform includes multiple paper bags delivered thereon. The rotation table is configured to rotate the multiple paper bags at two opposite angles. The stacking device is configured to stack the multiple paper bags. The displacement device is mounted below the stacking device and is configured to deliver the multiple paper bags. The packaging device is connected on the displacement device and includes an entering platform, a press plate, and a glue sprayer. An inlet of the entering platform accommodates the press plate, and the glue sprayer is fixed on a predetermined position of the entering platform. The paper feeder is connected with the packaging device and is configured to deliver multiple packing papers onto the entering platform.

The present invention is directed to a process for manufacturing a flexible package suitable for containing a food or beverage ingredient and suitable for use with a food or beverage preparation machine, wherein said process comprises punching a flexible flat blank sheet between a plunger and a cavity that are movable relative to one another. According to the invention, the plunger has a concave end side and convex lateral sides, and the profile curvature of its end side is identical to the profile curvature of each of its lateral sides.

A method of forming and filling a pouch, comprises forming opposing walls of a film; sealing the opposing walls of film together to form at least one pouch; filling an interior section of the at least one pouch through an opening in an upper portion of the at least one pouch with a flowable material; forming a top sealed expressing-shaped region to close the opening in the at least one pouch; and cradling the pouch with a foldable flat that is more rigid than the pouch that can be folded or rolled to compress the pouch to express the flowable material through the expressing shaped region.
