  • Patent number: 11180305
    Abstract: To provide a microwave pouch that favorably prevents both of hole formation of the pouch and spurting of contents, with a simple structure. A microwave pouch (10) includes a self-venting mechanism (20). The self-venting mechanism (20) has an annular venting seal (30), a steam release part (40) surrounded by the venting seal (30), and a movable piece (60) defined by a slit (50) formed in the steam release part (40). The venting seal (30) has a seal peel initiation part (31) where peeling is started by steam generated inside the pouch (10) during heating. The slit (50) includes slit both ends (51), and a slit intermediate part (52) formed to extend from the slit both ends (51) toward a region away from the seal peel initiation part (31) and connecting the slit both ends.

  • Patent number: 11059650
    Abstract: A packaging bag composed of a multilayer film and having a steam releasing mechanism. The multilayer film has at least a base layer and a welding layer and has a moisture content of not more than 1.0% in a state in which the packaging bag is filled with a content. The steam releasing mechanism has at least a steam releasing portion formed to have a maximal width of 3 to 20 mm. The internal pressure of the packaging bag is kept to be not more than 115 kPa during a period from the time the internal pressure is released through the steam releasing portion as a result of an increase in the internal pressure caused by heating in a microwave oven to the time the heating in the microwave oven finishes.

This can prevent breakage of the bag or leakage of the content due to the increase of the internal pressure by the heating, and reduces or prevents effectively thermal damage irrespective of properties of the content.

  • Patent number: 8485400
    Abstract: A pouch with a nozzle has a reliable dispensing opening. The pouch holds liquid contents. The pouch has a shell portion formed by sealing two plies of plastic together to form a pouch volume and a nozzle portion which communicates with the inside of the shell portion. The nozzle portion is formed by a series of embossments which form a reliably open passage for dispensing fluid. Three sets of embossments include a plane shape, a dot shape or a line shape.

  • Patent number: 8070016
    Abstract: A pouch is formed out of two sheets of plastic heat sealed over most of the edge length. The pouch has an expanding bottom feature and has a pouring spout formed by raised impressions in the corresponding sheets of plastic that form matching embossments. When the pouch is squeezed, the embossments open further apart to form a larger fluid passage at the outlet. The outlet of the pouch is opposite the bottom of the pouch and in at least one embodiment has a region on both sides of the outlet that are kept free from heat sealing during manufacture. The outlet also has a frangible line of weakness for easy opening. The outlet passage has two sets of embossments that meet along a center line to more fully expand the central portion of the pouch.

  • Patent number: 8047716
    Abstract: A branch type standing pouch which includes a pouch front side member including a pouring-out nozzle backside portion which constitutes a backside of a pouring-out nozzle by being folded back and a pouch body front side portion continuous therewith; a pouch backside member constituting a backside of the pouch body; a pouring-out nozzle front side member; and a bottom member. The pouch front side member, the pouch backside member, the pouring-out nozzle front side member, and the bottom member are respectively formed of plastic film and heat-sealed to each other so that a pouring-out nozzle is formed in a branched manner from a top of a pouch body. In this pouch, two symmetrical nozzle reinforcing areas are formed on both sides of a first protrusion as a result of a provision of the first to fourth protrusions. As a result, the branch type standing pouch in which the pouring-out nozzle can be fixed upright at a time of opening is obtained.

  • Publication number: 20090134185
    Abstract: The invention provides a pouch for refill of contents 10 manufactured by forming a bag from a base material film made of a flexible package material such as a resin film so that a nozzle 16 for discharging the contents is formed so as to project obliquely upward at a corner of a body part 11. In the pouch 10, in order to prevent closing of a discharge port 16a at the time of discharging the contents with a simpler structure and easily transfer the contents to another container such as a plastic bottle or a glass bottle, a ridge line guiding part 17 is formed in a base part 16a of a nozzle 16 so that a ridge line 20, formed in the surface of the base material film when the pouch is pressed from the inside by the contents filled, is guided along a center line of a the nozzle.

  • Patent number: 4195566
    Abstract: A multicolor rotary press for bottles has rotary transfer cylinder with a silicone rubber periphery having of six retractable transfer surfaces disposed at equal angular intervals therearound and alternating with stationary transfer surfaces. During the rotation of the transfer cylinder, one of two stamping photogravure rolls in rotational engagement therewith transfers an image with a first color to that retractable transfer surface then coming thereunder. The image bearing surface comes under the other roll and is temporarily retractable and that roll transfers another image with a second color to the next stationary transfer surface. Both image bearing surfaces travel past and engage a bottle rotating while engaging the transfer cylinder to print the image on the bottle.
