Provided is a bonding method capable of bonding with an inexpensive structure while avoiding an increase in the overall size of the device. The bonding method comprises: an arrangement step for locating a cylindrical body between two sheet-shaped members; a cylindrical body bonding step for applying an ultrasonic wave from the outer surface of a first sheet-shaped member through a horn part and applying heat from the outer surface of a second sheet-shaped member through an anvil part, in a state in which the cylindrical body is arranged between the two sheet-shaped members; and a shoulder part bonding step for directly bonding, through a pair of heating parts, the two sheet-shaped members to each other while the two sheet-shaped members are interposed between the pair of heating parts.

Bonding method and bonding device

A vertical bag-making/filling/packaging machine () includes: a top folding portion () which forms a first fold (F) by folding a side of a band-shaped film (F) into a Z-shape; a bottom folding portion () which forms a second fold (F) by folding a center of the film (F) into an M-shape; a top seal portion () which forms a top gusset (G) and a spout portion (G) protruding from the top gusset (G) by heat-welding the first fold (F) and side edges (Eand E) of the film (F) so as to make the film (F) into a tube shape; and a bottom-seal portion () which forms a bottom gusset (G) by heat-welding the second fold (F).

Vertical bag-making/filling/packaging machine, manufacturing method of film packaging bag with content, and film packaging bag with content

A vertical bag-making/filling/packaging machine () comprises: a film supply portion (); a film engaging portion () which is engaged with a film (F); a vertical seal portion () which makes the film (F) into a tubular shape; a film conveying portion (); a film clamp () which holds the film (F) at the film engaging portion (); a film tension releasing portion () which loosens the film (F); a filling portion () which inputs the content (X); a weighing portion () which weighs the content (X); a lateral sealing portion () which makes the film (F) into a bag body (G); and a cutter which cuts off the bag body (G).

Vertical bag-making/filling/packaging machine, manufacturing method of film packaging bag with content

A vertical bag-making/filling/packaging machine () comprises: a film supplying portion () which lets out a film (F) from a roll (Fr); a bag-making guide () which folds the film (F) into a tubular shape and changes a conveying direction downward; a vertical sealing portion () which thermally seals side edges of the film (F) to each other in an up-down direction so as to make the film into a tubular shape; a film conveying portion () which conveys the film (F) downward; a filling portion () which loads a content (X) into an interior of the film (F); a lateral sealing portion () which thermally seals the film (F) in a left-right direction so as to make a bag body; a square-bottom sealing portion () which expands a bottom of the bag body to a rectangular shape from an inside and then thermally seals the bottom to form a rectangular bottom surface; and a cutter () which cuts off the bag body from the film (F).

The present invention aims at sterilizing a film without using liquid hydrogen peroxide.

The break-off spout of the present invention includes: a spout main body () having a break-off section () formed via a weakened section () such that an annular section () having a through-hole formed therein protrudes to the tip side; and a pair of left and right cover members () integrally formed with the spout main body () via hinge sections provided below the weakened section (). The pair of left and right cover members () are formed in a shape such that, when the cover members are engaged with each other, the cover members cover a portion of the spout main body () above the hinge sections including the break-off section (). An insertion port () through which deformation means that deforms the annular section () and blocks the through-hole can be inserted is provided in the cover members ().

Break-off spout, pouch having a break-off spout, production method for pouch having a break-off spout, food or beverage in pouch having a break-off spout, and production method therefor

Breakable spout () of the present invention individually comprises spout body () and cover () that covers an outer circumference of spout body (). Spout body () comprises cylindrical part () that has a center hole that serves as a flow channel () and breakable part () that is breakable at the tip end of cylindrical part (). Cylindrical part () has a first protrusion () on an outer circumferential surface thereof. The cover has second protrusion () on an inner circumferential surface thereof. Second protrusion () engages first protrusion () when cover () is fitted to spout body () such that spout body () is covered with cover () from the tip end side of cylindrical part (). Cover () covers spout body () and is secured when the first protrusion () engages the second protrusion (). Opening () is formed in the portion of cover () that corresponds to communication hole () of annular part () when cover () is fitted to the spout body and covers spout body ().

Spout, package with spout and method of manufacturing the same

A vertical filling and packaging machine of the present invention includes tension devices () that are disposed near positions of ironing rollers () and that pull both sides of cylindrical film () laterally outward. Tension devices () pull both sides of cylindrical film () laterally outward to flatten a portion of cylindrical film () before the pair of ironing rollers () sandwiches the portion of cylindrical film (), wherein the content has been injected into the cylindrical film (). As a result, when lateral seal part () is formed on cylindrical film () by lateral seal device (), lateral seal part () is not easily wrinkled.
