BAG AND BLANK THEREFOR.
. Specification of Letters Patent.
Patented Sept. 29, 1908.
Application filed February 27, 1906. Serial No. 303,292.
To all whom it may concern:
Be it known that I, PHILIP A. FRYE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Bags and Blanks Therefor, of which the following is a specification.
The object of this invention is to provide a bag of the standard satchel-bottom type, and a blank therefor, which shall require less ma terial for a given capacity than has heretofore been necessary.
The invention is applicable to bags of any material, but will be described by way of example as applied to a paper bag intended more particularly for containing flour. Bags of this character have been heretofore produced by running the pa er from the rolls through a tubing machine y which it is folded and the side seam pasted, the flattened tubes being then cut into the desired lengths or blanks by a cut extending in a straight line between opposite points on the flattened tube. I have now discovered that a material saving of paper may be effected by means of a modified form of out, said out extending between opposite points on the flattened tube in a broken or curved line lying to one side of a straight line joining said points.
For a full understanding of my invention reference is made to the accompanying drawings wherein Figure 1 is a face view of portions of two blanks cut in accordance with my invention; Fig. 2 is a similar view illustrating the manner of foldin and pasting the blank to form the bottom ofthe bag; and Fig. 3 is a face view of ortions of two blanks cut froma flattened tu e on a curved line.
Referring to the figures, 1 represents a blank or flattened tube section cut in suitable lengths by cuts 4, 5 extending between opposite points 2, 3; said cuts 4, 5 may intersect at the central line of the blank, or as shown in Fig. 1 the cut on one side may comprise two straight portions 4, 5 and a central tongue 6. This tongue 6 aflords a hold for thenipper of the bottoming machine, and permits the bottom to be expeditiously formed; and its removal provides a finger slot forthe top of the bag to facilitate its opening for filling; furthermore the tongue increases the pasted surface and therefore the stren th of the finished bag. It will be observe that the cuts deternnne the form of the top of one blank and of the bottom of the next.
The solid lines 7 and8 in the several figures represent longitudinal cuts which subdivide the bag bottom into two primary folds 9, 10 and two finishing folds 11, 12. The dotted lines in Figs. 1 and 3 represent the lines of folding, these cuts and folds being of the usual form. In folding the bag bottom the primary folds 9, 10 are turned inward as shown in Fig. 2, paste being applied transversely to each of these folds, as indicated at 13, 13. The inner and outer finishing folds 11, 12 are then successively folded inward and are pasted to the primary folds, the outer fold 12 being also secured to the inner fold 11 at the overlap by paste 14.
The manner of cutting, folding and asting the blank shown in Fig. 3 is in al respects as above described, the only difference being that this blank is cut on a curved line forming an arc of which the straight line joining the opposite points 2, 3 is the chord.
In bags of this character it is customary to secure the top, after the bag is filled, by bringing the ends and sides to the center for tying. As the filled bag is somewhat flattened in form, the diameter between the points 2, 3 being longer than the diameter at right angles thereto, it is obvious that more paper is required for the central tie in the first-named direction than in the second. By cutting the flattened tube on a broken or curved line as above described, it will be seen that the blank is out long enough to permit the sides to be drawn together on the onger dimension for tying, while on the shorter dimension sufficient though less material is also provided for this purpose. The material thus saved at the top of one bag is utilized in the finishing folds 11, 12 at the bottom of the next bag, providing the necessary overla for pasting. The fact that some materia is cut away from the primary folds 9, 10 is unobjectionable, since these folds are in any case pasted at some distance from their inner edges, as indicated in Fig. 2. My form of blank results therefore in the saving on each bag of a quantity of paper which depends on the amount of deviation of the broken or curved line of the cut from the straight line joining opposite points on the flattened tube. The resulting bag has its greatest depth at two points which are diametrically opposite, at the ends of the longest transverse diameter and directly above the apices of the triangular primary folds; the least depth of the bag is at points at opposite ends of its shortest transverse diameter, the depth in all cases affording sufficient material for the central tie.
I claim 1. A bag blank for satchel-bottom bags comprising a flattened tube cut transversely at its upper and lower ends on parallel broken and curved lines, the line at the top being incurved and the line at the bottom being correspondingly outcurved, and having both plies longitudinally cut at the lower end to provide primary and finishing folds, substantially as described.
2 A satchel-bottom bag consisting ofa flattened tube cut transversely at its upper and lower ends on parallel broken or curved lines, the bag bottom comprising pasted primary and finishing folds constituting a satchel bottom, said bag having its greatest depth at two diametrically opposite points above the apiees of the primary folds, substantially as described.
In testimony whereof, I aflix my signature in presence of two witnesses.
PHILIP A. FRYE.
