Patented June 10, 1930 UNITED "STATES PATENT OFFICE JOHN C. REDINGTON, OF GENEVA, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO ST. REGIS PAPER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK MEANS non otosmo THE VALVES or VALVE BAGS- Application filed March 9, 1928. Serial No. 260,440.
invention relates to means for closing the valve of a valve bag and for sealing the closure so that the valve opening cannot be opened and reclosed without leaving evidence thereof. Details of the invention will appear as the description proceeds.
In the accompanying drawings forming a part of this specification, Figure l is a view of the end of a closed, filled and sealed bag embodying my invention; Fig. 2 is a section of an empty bag embodying my invention; and, Fig. 3 is a View similar to Fig. 1 but with parts broken away so as to show the operation of the valve closing means.
In the construction shown, a bag 10 is provided with an end closing reinforced seam 11 which closes the end of the bag except for a valve opening 12. A draw string 13 is run through the end 14 of a valve 15 and the ends of the draw string are threaded out through the end closing seam 11. After the baghas been filled with material 16 through the valve opening, draw string 13 is pulled to close the end of the valve in the manner shown in Fig. 3. In the construction shown, 14 is disclosed as being an extension attached to valve 15 formed by the folding in of the walls of the bag, and this extension is preferably of flexible material and may be of cloth. After the bag has beenfilled and the draw string pulled, as shown in Fig. 3, a seal 17 may be placed over the strings in such a way that the valve cannot be opened without breaking the seal. Under normal circumstances the valve willremain securely closed after it has been closed by draw string 13 so that seal 17 is not required under normal conditions except as a guard against intentional tampering with the contents of the bag. It will be readi- 1 ly understood that a valve sealed, as shown in Fig. 1, cannot be opened without disrupting seal 17 and so showing the evidence of having been tampered with.
Various changes may be made within the scope of the appended claims.
By draw string in the appended claims is meant a string threaded through fabric and adapted to gather it when pulled.
\Vhat I claim is:
1. A valve bag comprising a flap directed into the interior of the bag and a string connect-ed to said flap and extending outward through the wall of the bag and adapted to pull the flap into valve closing position after the bag has ben filled.
2. A bag having a filling valve in one corner thereof, a seam closing the end of the bag, a draw string attached to the valve and passing outward through the seam and adapted to close the valve after the bag has been filled.
3. A valve bag having one corner folded in to form a valve, a flap extension attached tosaid valve, a draw string attached to the flap and extending to the outside of the bag and adapted to pull the valve to valve closing position after the bag has been filled.
4. A valve bag having a valve flap and a draw string attached to the flap and extending to the outside of the bag and adapted to pull the flap to valve closing position after the bag has been filled and a seal applied to the draw string and holding it in valve closing position.
5. A filled valve bag having its valve closed by a drawstring extending to the outside of the valve and the draw string held in valve closing position by a seal.
In testimony whereof, I have hereunto signed my name to this specification.
' JOHN G. REDINGTON.
