Definitions

  • the present invention relates to such valve bags, usualfy constructed as multi-ply paper bags, as are provided with a tube attached in the valve formed by folding in a corner of the bag.
  • the bag is filled through this tube, which is then sealed at its outer end.
  • the invention has for its object to enable the valve tube to be sealed in a single operation both readily and effectively after the bag is filled. Further objects and advantages of the invention will become apparent from the following description of some difierent embodiments of the device, reference being had to the accompanying drawings, in which Fig. 1 is a side view of the valve corner of the bag, the valve being in the condition suitable for filling the bag, and
  • Fig. 2 is a longitudinal section through the valve in the same condition.
  • Fig. 3 shows the valve corner of the bag seen from above.
  • Fig. 4 is a longitudinal section through the bag valve after filling of the bag and sealing of the valve tube.
  • Figs. 5 and 6 show another embodiment of the device in the same manner as Figs. 2 and 3. while Figs. 7 and 8 show a third embodiment thereof as seen in section through the valve corner of the bag and obliquely from above. respectively.
  • a sleeve or tube I of relatively pliable material such as paper, preferably crned paper. or the like.
  • the outer end of the tube I projects but a short distance from the valve and is provided with a tongue 2 of relatively stiif material. such as pasteboard or the like, approximately in the form of a segment of a circle and attached to the top portion or wall of the tube by means of adhesion or in any other way.
  • the extension of this tongue in the transverse direction of the valve is somewhat less than the width of the tube attached in the valve in the normal flattened condition thereof.
  • the tongue 2 with its straight base edge extending in the transverse direction of the valve is a short distance inside the outer end of the tube I, in other words, approximately at or just inside the outer edge of the top wall of the valve.
  • the bag When the bag is to be threaded on to the filler tube of the valve bag filling machine by means of the valve, the bag is taken by the valve with one hand so that the valve is subjected to pressure by the hand from both sides of the bag.
  • this tongue bulges and expands the valve opening, as shown in Figs. 1 and 2, whereby the threading on of the valve of the bag to the filler tube is facilitated.
  • the outer end of the tube 1 is sealed by folding in the tongue 2 into the valve opening or rather into the pocket or so-called blind valve that is formed in a manner known in and per se between the bottom of the valve opening and the lower portion or wall of the valve tube I attached by means of adhesion or in any other manner to the bottom of the valve opening only with its inner end.
  • the tongue 2 is glued to the inside of the top portion or wall of the tube l, is that the glued portion would be subjected to too great strain and would come loose too easily on folding in of the tongue into the blind valve, if, in this embodiment thereof, the tongue were instead glued to the outside of the tube l.
  • the two embodiments according to Figs. 5 and 6 and Figs. 7 and 8 differ fromthe embodiment according to Figs. 1 to 4 by the tongue 2 being provided with a base flap 2a separated from the tongue proper 2 by means of a folding line 3.
  • the tongue 2 being provided with this base flap 2a defined by means of the folding line it may be glued or possibly otherwise attached by means of this flap not only to the inside of the top portion or wall of the tube l but also to the outside thereof as shown in Figs. 5 and 6, or internally in the valve opening proper to the upper wall thereof, as shown in Figs. '7 and 8, or externally to the last-mentioned wall.
  • the base flap 2a triangular form, as shown in Fig. 8, in order that it may be glued to the triangular portion of the upper wall of the valve
  • the number of the paper layers forming this Wall when using a certain method of foldin in constructing the valve, will be reduced, and consequently, the Wall in question thinner than in other places. so that the thickening of the said wall of the valve caused by gluing the flap 2a thereto Will not be very conspicuous.
  • the folding line of said tongue extends transversely of said tube near the outer end of said valve.
  • folding line 3 which thus replaces the rear edgelfl. tongue of relatively stiiT material resistant to of the tongue in the embodiment according to" Figs. 1 to 4, while the base flap 2a situated inside the folding line 3 serves as.a means of attachment for the tongue or for.”strengtheninggthe.
