Definitions

  • the invention also provides an open mouthed bag of the type which has two side gussets and whose bottom is closed so as to trap the two gussets such that when the bag is filled it automatically forms a substantially planar, rectangular base portion which lies substantially perpendicular to its side walls, with a respective pair of triangular panels formed by each gusset lying over and substantially parallel to said substantially planar rectangular base portion and wherein at least parts of said two pairs of triangular panels are secured to said planar base portion such that the contents introduced in use to fill the bag are substantially prevented from entering between said pairs of triangular panels and the planar base portion and such that a substantially undistorted planar base can be maintained when the bag has been filled.
  • Fig. 4 shows a number of nominal fold lines, discussed further hereinafter, these do not need to be pre-formed in the blank but are established at different stages during the formation of the bag, one (54) actually being established only during eventual filling of the bag. However, it is useful to the understanding of how the bag is established and how the present invention is applied to this particular bag formation if the nature and function of these nominal fold lines is explained.
  • transversely extending nominal fold lines 46, 48 which nominally delineate closure panels 50, 52 which will be used to form a roll bottom for the bag.
  • a still further transversely extending, purely nominal fold line 54 is shown on the blank at a distance "b" from the nominal fold line 48, substantially equal to the depth "a" of the gussets 14b, 14a, ie equal to the width of the panels 18',16', 18,16 in Fig. 4. It is stressed that the transverse nominal fold lines 46,48, 54 are not necessarily formed as such and are merely for the purposes of assisting the description. Lines 46,48 show where the bottom of the bag is folded to form a roll bottom and line 54 shows where a fold is automatically generated in the bag to form the bag base 28 when the bag is eventually filled with a particulate material.
