VALVE BAG Filed Dec. 18, 1936 INVENTOR i" (www ATTORNEYS vPatented Jan. 11, 193s UNITED STATES PATENT OFFICE A y VALVE BAG Douglas E. Scott, Chagrin Falls, Ohio, assigner toThe Chase Bag- Company, Cleveland, Ohio,
a. corporation of Delaware Application December 18, 1936, Serial No. 116,608
. 4 Claims.
I ordinary valve.
Heretofore valve bags have been filled through a feed .pipe inserted between the usual valve ap and the end flaps. It has also been proposed to provide such bags with a paper valve-sealing tube open at both ends and having its inner end aiiixed in the valve opening, and the outer end thereof designed to form a sealing closure. However the use of such sealing tubes has proven objectionable due to the fact that the tubes have a tendency to hug the filling spout and prevent the escape of air, thus slowing down lling operations.
The principalobject of the present invention is to provide a. valve sealingtube which obviates the foregoing objections.
Other objects and advantages of the invention will be apparent from a consideration of the specification in connection with the accompanying drawing, in which:
Figure i is a plan view of a bag embodying my invention, showing the valve sleeve in extended position;
Figure 2 is a section on line 2 2' of Figure 1, with the filling spout in position;
3 Figure 3 is a fragmentary plan view of the bag showing the valve sleeve partially folded;
Figure 4 is a view similar to Figure 3 showing the valve sleeve completely folded; and
Figure 5 is an enlarged section taken on line 5-5 of Figure 2.
Referring more particularly to the drawing I0 denotes a paper bag having the usual valve flap II, and inner and outer end flaps I2 and I3 respectively which close the upper end of the valve when cemented together, by means of a layer of 'paste I4.
A valve sealing tube I5 of plain kraft paper is inserted into the valve opening and is secured at one side of its inner end to the valve flap II, by means of a,- layer of paste I6. The upper edgeor face of the flapvalve II` is secured to the inner end flap I2, as by means o f adhesive I1. The adhesive 'I6 and II does not extend outwardly very far, thusleaving the outer end I8v of the -paper tube I5 free to be folded and tucked into the valve opening after the bag has been filled. Filling of the bag is effected in 4a customary manner through the opening I9 of the insertion of the filling spout 20, the tube will folded corners, is folded downwardly and in- (Cl. 22S-62.5)
a feed pipe or spout 2li which is inserted into. the paper tube I5.
Practice has proven that when a tube such as just described is opened by the packer for not stand away from the spout sufficiently to permit the air to escape. In other words the tube will hug the spout so closely that the air is trapped. In this connection it should be noted that the tube must be of relatively thin nexible 1 tough paper to permit of the flap being effectively folded and tucked.
According to the present invention I make the tube I5 of approximately 40 lb. plain kraft paper. Within the tube and ailixed thereto by means of a gummy pliable adhesive 2i, is a sleeve or lining member 22 of approximately 30 lb. crinkled or crimped or creped kraft paper. When the tube is opened by the packer, the crinkled sleeve and the layer of gummy adhesive functions to 20 hold -the' tube open and sufficiently away from or out of contact with the filling spout to permit of free escape of air through air space 24 between the'sleeve and ller tube. In short the double walled tube is so pliable and of such consistency that it can readily be opened orclosed to any desired degree and will remain more or less fixed in such position.' The sleeve 22 is preferably co-extensive with the tube I 5, and the layer or wall of gummy adhesive 2| preferably covers the entire opposing faces of the tube and its sleeve.
A thumb opening or cut 23 is provided at one side of the tube to facilitate opening thereof. 35 After the bag has been filled, and the filling spout removed, the .tube is preferably first attened, then the corners 23 are folded downwardly and inwardlyv as illustrated -in Figure 3, and finally the outer end of the tube including the ends and having its inner end aiiixed in the valve opening and having its outer end extending outward from said opening and designed to form a sealing closure at said outer end, said sealing tube having'a flexible, pliable crinkled 55 sleeve oi' less weight than said tube ailixed therein.
2. A bag having a valve opening, a valve sealing tube open at both ends and having its inner end affixed to the inside of the -walls of the valve and having its outer end extending far enough to fold, there being a space between the tubel and the outer edge of the valve adapted to receive the 4folded end of the tube, said sealing tube having a ilexible pliable crinkled sleeve of relatively light material aixed therein, said@ I at its inner end, the outer end ot the tube exhaving a exibie crinkled pliable sleeve aiiixed therein.
4. A bagredy opening',v a valve sealing tube open at both ends fand having its inner end aillxed in the valve opening and having its outer end extending outward from said openingand designed to form a sealing closure at said 'outer end, said tube comprising an outer layer of plain kraft paper and an inner layer oi crinkled paper, said layers being amxed together by a layer of adhesive.
