Abstract
Abstract For the fabrication of a bag-in-box (BIB) package, there is first provided a semifinished, collapsed BIB package wherein a flattened bag is placed within a collapsed box and secured to at least one of its inside surfaces by means of an adhesive. After erecting the package, the bag is inflated into close internal contact with the box by introducing a gas under pressure through a fitment attached to the bag and projecting outwardly of the box. The opposite ends of the box are closed with sets of foldable end flaps, with the aid of an adhesive. Preferably, the bag is further secured to the inside surfaces of a pair of opposed ones of the four bottom end flaps of the box. The opposed pair of bottom flaps are held folded out during the introduction of the pressurized gas into the bag, in order that the bottom end portion of the inflated bag may make neat contact with the inside surfaces of the box. There is also disclosed herein an apparatus for erecting, filling, and sealing thus fabricating the BIB package.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
316 words
An apparatus for fabricating and filling bag-in-box packages, comprising: (a) means for feeding a succession of semifinished bag-in-box packages along a first predetermined path, each semifinished bag-in-box package comprising (1) a box having a set of four panels connected together and forming a rectangular tube, and two sets of end flaps foldably connected to the panels for closing the opposite ends of the rectangular tube, (2) a bag disposed within the box and formed by two substantially rectangular, superposed layers of flexible material hermetically sealed together, one of the layers of the bag being secured to at least one of the inside surfaces of the box by means of an adhesive, and (3) a fitment attached to the bag and projecting outwardly of the box; (b) means on the first predetermined path for inflating the bag of each semifinished package into close internal contact with the box by introducing a gas under pressure into the bag through the fitment; (c) means on the opposite sides of the first predetermined path for closing the opposite ends of the rectangular tube, formed by the panels of the box of each semifinished package, with the sets of end flaps to provide finished bag-in-box packages; (d) a series of package carriers movable along a second predetermined path; (e) means for loading the finished bag-in-box packages one on each package carrier, with the fitment of each package directed substantially upwardly; (f) means for feeding the package carriers, together with the packages loaded thereon, along the second predetermined path; (g) means on the second predetermined path for filling the packages on the package carriers with a desired product through the fitments; (h) means on the second predetermined path for capping the fitments of the filled packages on the package carriers with dispenser mechanisms; and (i) means for unloading the filled and capped packages from the package carriers on the second predetermined path.
Claim 2
Independent Claim
316 words
An apparatus for fabricating and filling bag-in-box packages, comprising: (a) means for feeding a succession of semifinished bag-in-box packages along a first predetermined path, each semifinished bag-in-box package comprising (1) a box having a set of four panels connected together and forming a rectangular tube, and two sets of end flaps foldably connected to the panels for closing the opposite ends of the rectangular tube, (2) a bag disposed within the box and formed by two substantially rectangular, superposed layers of flexible material hermetically sealed together, one of the layers of the bag being secured to at least one of the inside surfaces of the box by means of an adhesive, and (3) a fitment attached to the bag and projecting outwardly of the box; (b) means on the first predetermined path for inflating the bag of each semifinished package into close internal contact with the box by introducing a gas under pressure into the bag through the fitment; (c) means on the opposite sides of the first predetermined path for closing the opposite ends of the rectangular tube, formed by the panels of the box of each semifinished package, with the sets of end flaps to provide finished bag-in-box packages; (d) a series of package carriers movable along a second predetermined path; (e) means for loading the finished bag-in-box packages one on each package carrier, with the fitment of each package directed substantially upwardly; (f) means for feeding the package carriers, together with the packages loaded thereon, along the second predetermined path; (g) means on the second predetermined path for filling the packages on the package carriers with a desired product through the fitments; (h) means on the second predetermined path for capping the fitments of the filled packages on the package carriers with dispenser mechanisms; and (i) means for unloading the filled and capped packages from the package carriers on the second predetermined path.
Claim 3
Dependent Claim
29 words
The apparatus according to claim 1, wherein each package carrier has an upwardly open seat formed thereon for relatively closely receiving and holding one of the finished bag-in-box packages.
Claim 4
Dependent Claim
53 words
The apparatus according to claim 2, wherein the box of each package has a bevel flap at one end thereof, with the fitment projecting outwardly of the box through the bevel flap, and wherein the seat of each package carrier is slanted for holding one package thereon with its fitment directed approximately upwardly.
Claim 5
Dependent Claim
124 words
The apparatus according to claim 1, 2 or 3, wherein the loading means comprises: (a) a loading conveyor extending parallel to part of the second predetermined path, the loading conveyor having a plurality of transverse ridges formed at constant longitudinal spacings thereon for positive engagement with the respective bag-in-box packages; (b) means for placing the successive packages transversely on the loading conveyor so as to be in positive engagement with the transverse ridges thereon; and (c) a fixed guide disposed diagonally over the loading conveyor for relative sliding engagement with the packages traveling thereon, the fixed guide coacting with the loading conveyor to cause gradual sideways motion of the packages from the loading conveyor onto the respective package carriers on the second predetermined path.
Claim 6
