Definitions

  • the valve bag is provided with a closure device for the valve consisting of a member made of cardboard, paper or other similar material fixed to the outer lip of the I valve and having outside the bag a free transverse flappreferably of substantially the width of the valve, which flap is' arranged so that after filling the bag, it can be folded back and introduced into a kind of'pocket formed on the outer face of the inner lipof the valve, having substantially the width of said valve, and of which the opening is turned outwardly.
  • a closure device for the valve consisting of a member made of cardboard, paper or other similar material fixed to the outer lip of the I valve and having outside the bag a free transverse flappreferably of substantially the width of the valve, which flap is' arranged so that after filling the bag, it can be folded back and introduced into a kind of'pocket formed on the outer face of the inner lipof the valve, having substantially the width of said valve, and of which the opening is turned outwardly.
  • Fig. Us a partial section of a valve bag through the median plane passing through the axis of the the closure device before the yalve is closed;
  • Fig. 2 is a section identical with Fig. 1 but shows the valve closed
  • Fig. 3 is a plane view of the bottom of the bag fFigs. l and 2;
  • Fig. 4 is a view similar to Fig. 1 of amodifiedembodiment
  • Figs. 5 and 6 are respectively similar views to Figs. 1 and 2- but showing another modified embodiment.
  • a closure part I made of relatively flexible paper, advantageously of creped paper, is fixed to the outer lip 2 of the valve of a bag 3, preferably by means of staples. Said part I is extended beyond the staple which is nearest the outer opening of the valve by a part4 which forms a free transverse. fiap of substantially the width of the valve.
  • the i .ner lip5 of the valve is cut in the angles over a part of its length, from its end'within the bag, and the part 1 between said incisions 6 is folded back towards the outer opening of the valve, on the upper side of said inner lip 5, about a line A-B passing through the starting point of said incisions 6.
  • the closure device is similar to thatof Figs. 1 to 3 with the sole difference that the pocket is formed by 'the inner lip 5 of the valve and a piece of paper .or cardboard 1 covering the upper face of said;
  • a similar piece of paper or cardboard can also be provided in the case of the pocket of Fig. 1 to the filling tube and the filling of the bagare reinforce the face I of the pocket'and this reinforcing element 8 (Figs. 5 and 6) need not be permanently fixed to the bag but can be folded to form a U-shaped member fitting onto the pocket of the valve and not secured theretoby any" means.
  • the reinforcing element extends beyond the valve until it comes at a short distance from the outer end of the flap 4 (Fig. 5) thereby considerably facilitating the'placing in position of the bag on the filling tube and the folding together of the elements .4 and 8.
  • the free transverse flap is not. necessarily integral with the part fixed to the outer lip of the valve but it can be attached to the latter and can be made of a diflerent material.
  • the, closure part fixed to the outer lip can v, be fixed on the outer or inner faces of the latter and be of smaller width than that of the valve,
  • a valve bag having its inner valve'lip provided with two incisions extending from the inner end of said lip towards the outer valve end upon a part of the length of said lip, the lip portion between said incisions being folded back,
  • a valve bag as in claim 1 further provided with a U -shaped reinforcing member freely fitted over the fold between the folded back lip part and the nonincised lip part and having a fold-" able projection out of the valve beyond the outer edge of said folded back lip part.
  • a valve bag as infclaim 1 further provided with strap of reinforcing foldable material having substantially the same width as'the folded back lip part, inserted inthe valve and having a' hook-like part freely fitted over the fold be-- tween the folded back lip part and the non in- 5.
  • the outer pocket wall forms a flap free within the valve, and a sheet-like member carried by the bag within the valve at least the fraction of said member adjacent the outer valve end is free within the valve,.i. e. not adhered to cised lip part, said strap projecting o t of the ,valve beyond theend of said folded bac lip part.
  • the inner faceofthe outer valve lip but capable of being moved away from said lip to be rolled or tucked into the pocket and within the valve together with said free p ew 8 sheet-like flap being made of a sheet of supple sheet of strongmaterial like card-board or strong part .of theouter pocket wall to thereby close the valve wall includes a 6.
  • valve closing means including a pocket formed on the outer face of the inner valve lipfithe inner end of said pocket being closed while the outer end is open, and a flat foldable member a part of which is provided within the valve passageway and adhered to the bag bottom and the remaining portion of said member projects out of the valve to be insertable into said pocket, said flat foldable member consisting ⁇ in a sheet-like flap free of connection with said inner valve lip.
  • valve closing means including a pocket formed on the outer face of the inner valve lip, the inner end of said pocket being closed while the outer end is open, and a flat foldable member a part of which is provided within the valve passageway and adhered to the bag bottom and the remaining portion of said member projects out of the valveto I be insertable into said pocket, said flat foldable -member consisting in a sheet-like flap free of are capable of being rolled or tucked together within the valve passageway.
  • valve closing means including a pocket formed on the outer face of the inner valve lip, the inner-end of said pocket being closed while the outer end is open.
  • V a flat foldable member a part of which is provided within the valve passageway and adhered to the bag bottom and the remaining portion of said member projects out of the valve to-be insertable into said pocket, said flat foldable member consisting in a sheet-like flap free of connection with said inner valve lip, and the inner valve lip being outer valve lip;
