Definitions

  • My invention relates to valve bags, more particularly to flat bottom bags, and its main object is to adapt this kind of bag for lling by means of a spout to be inserted'obliquely downwards into the bag which is maintained in substantially tion much smaller than valve section, which considerably diminishes bag filling speed.
  • a spout is necessary in the case of iilling a bag simply by gravity.
  • My invention consists inpart of an outer valve lip, composed of a member applied on the bottom l5 and su'iciently exible and elastic as to allow of its being forced back by action of an oblique lling spout and to return to its closing position after 4removing the spout.
  • One may utilize, for example, to this end a member of crepe paper fabric, flexible matter such as rubber, etc.
  • Fig. 1 is a perspective view with pieces partly broken away, of the end of a flat bottom valve bag improved according to my invention
  • Fig. 2 is a perspective view of the outwardly viewed end of the same bag:-
  • Fig. 3d also a perspective View ofA said bag, but shows the opposite end to that comprising the valve;
  • Fig. 4 is a cross section along the lvalve axis with filling spout in position
  • Fig. 5 is a horizontal .view of the filling spout alone.
  • the bag-bottom is 55 formed ,in the usual manner by.:'the four over- ⁇ lapping panels I, 2, 3, '4A among vwhich panels I, 2, 3 are secured together by clips 5, while panel 4 remains free and forms the inner valve lip.
  • This panel 4 applies inwardly on a partof panels 2 and 3, which partly form the outer valve lip. 'Ihe overlapping part of the inner and outer valve lips thusr constituted being too short to.
  • this panel 10 is usually formed bypasteboard and also secured to panels 2, 3 along edges AB and AC, it is constituted lierein, according to my invention by crepe paper and secured to panels 2, 3'by the single cross row of clips 6, the edges AB andAC remaining free.
  • the subsidiary panel v'l may be folded up, without injury, as shown byj Fig. 4, so as to give free passageito oblique filling spout 8.
  • panel 1 After removing the spout, panel 1 returns automatically by its own elasticity to its original closing position, as ,shown by Fig. 2 and thus -forms a part of outer valve lip.
  • the filling spout 8 may be advantageously provided with a projecting .member 9 shaped sub.- stantially as a stem. f l
  • crepe paper instead of crepe paper, many other materials might be used, even a relatively stiff material which would be so incised on the extension of line AA as to open towards the right and the left ⁇ like aps on thrust of spout 8 and particularly of stem 9, and so flexible as to fall back of itself after removing 35 spout 8.
  • Panel 1 might extend no farther than clips 6.
