age a wide range of difierent materials in a l 2 Claims.

This invention relates to containers or bags of the so-called closed end type, as distinguished from valve bags, and presents a construction having a small opening at one top end to allow the introduction of material therein, said bag suitable manner after the bag is filled. v Bags of this type arefrequently formed of multi-ply paper bag stock, which may or may not be provided with gussets. The bags may be out to requisite bag length from continuous multi-ply bag tubes, paper strips or tape beingfolded over and secured to the top and bottom margins of the bag in a well known manner, to provide a leak-proof bag.

I have discovered that an opening for the introduction of material into a bag may be provided along the top margin of a strip sealed bag end, by providing a construction whereby the position and arrangement of the top of the bag, the'strip and the line of stitches or other strip securing means are such, that a portion of said stitches or securing means lying inwardly from one side of the bag, extends through the strip only, thus leaving an unsecured portion being constructed and arranged in such manner v that the opening may be readily sealed in any at one top-corner of the bag, permitting the introduction of material into the bag, said unsecured strip portion being adapted to be readily secured to the top margin of the filled bag, by

any suitable means, such as by stitching, stapling or other suitable means.

Therefore, an object of my invention, is to provide a bag construction having a sealing strip along the top margin thereof, the same being positioned and arranged in such manner. that a portion of the strip is initially unsecured to the bag, in order to permit the introduction of material thereinto, said strip being adapted to be readily secured to the top margin thereof after the bag is filled, in any suitable manner.

Another object is to provide a leak-proof bag, adapted. to package a wide range of materials, including rosin, asphalt and other materials which may .be introduced into the bag at temperaturessufiiciently high to permit such materials to flow therein in a liquid state, the bag end being closed by stitches, staples or the like, shortly after the liquid material is poured therein and beforethe liquid has had an opportunity to solidify to any considerable extent.

Another objectis to provide a relatively low cost b'ag, having a portion adaptedto receive a filling spout. such'bag. being adapted to packleak-proof manner. 1

Still another object of my invention is to provide a bag, which may be quickly and easily sealed by a relatively. wide'selective range of sealing operations, which may be performed either automatically or by hand, the same providing a neat and attractive package, free from protruding parts and adapted to be eificiently stacked or piled with similar bags.

Still another object is to provide a factured on existing bag machines, with little, if any, alteration of such machines, therefore providing a bag which can be produced at a relatively low cost.

Other and further objects of this invention will be apparent during the course of the following description.

In the drawing forming part of this specification:

' In t r ins. the metered rum or .my ml of crepe paper tape are folded over the ends of a bag, and are secured thereto in any suitable manner, frequently such operation being performed by sewing machines, although other satisfactory means, such as stapling or the use of adhesives, may be used.

A sealing tape or strip I2 is folded over the ends of the bag tube, and may be secured to they bottom end thereof by a straight row of stitches l3, in .a well known manner. The normal line of stitches through the sealing strip along the top margin of the bag, extends in a straight line across substantially two-thirds the distance across the top thereof, as indicated by the'numeral l4 and then extends angularly outwardly therefrom, as indicated by the numeral l5, to a point just inside the fold line of the strip l2, but beyond the top margin I6 of the bag l0, and thus continues in a straight line parallel to the top bag margin beyond th right hand side of the bag, as indicated by the numeral IT.

The above construction produces an initially unsecured sealing strip portio'n l8, of the same construction and design as the secured portion, which, on account of being initially unsecured to the top bag margin, is adapted to be lifted from the top of the bag, thus permitting-the introduction of material into the open end through a filling spout ,|9, as illustrated in Fig. 1. After the bag is filled, the initially unsecured strip portion I8 is placed over the top bag margins, as illustrated in Figs. 2, 3 and 4, and is adapted to be secured thereto in any suitable manner.

In Fig. 3 the numeral 20 indicates a line of stitches, forming a continuation of the line of stitches H, the same being made after the bag is filled as hereinbefore described, and if desired, may be performed by a movable stitching head. If desired, a row of staples-2|, forming a continuation of the line of stitches Il, may be used inplace of the stitches 20, to secure the strip .portion l8 to the filled bag, as illustrated in Fig. 4.

- bag, in order to secure the strip portion l8b to Obviously other suitable meansmay be used for securing the strip portion Hi to thefllled bag.

. Preferably the line '01 stitches l1, extending through the initially unsecured strip portion l8,

' should be'disposed as near the fold in the strip as possible, in order that the strip portion l8 may be snugly fitted along the top margin and secured thereto, after the bag is filled.- This feature provides a construction whereby the strip portion l8 may be placed subsequently straight across the top bag margin and thus provides a neat and attractive-bag, free from any unsightly folds, which is adapted to'be stacked in neat piles.

- In Figs. '7 and 8 is illustrated a. modified form of myinvention, having a bag formed and cut,

as previously described, but with a change in the right hand-portion of the top margin of the bag by way of a cut out portion 22 extending inwardly from the right hand side bag margin to a place corresponding to the point where the angularly 1 extending stitches I5 projectfrom the regular line of stitches l4 'in the preferred form of 'my invention. The topmargin of the bag along such cut out portion 22 is positioned slightly below the normal line of stitches Ma, extending through the strip and bag, and positioned slightly below the top bag margin Ilia as previously described.

This form of my invention provides a construcbe secured to the bag by a line of stitches 23, as

illustrated in Fig. 7, the same being disposed below the line of stitches Na in such manner that they extend through the strip portion I8a and the bag. If desired for certain types of packaging, the strip portion Ilia. may be secured to the filled bag by a row of staples 24, disposed substantially in the same manner as the line of stitches 23, as

illustrated in Fig. 8. Obviously other suitable securing means, including adhesives may be used if desired.

Figs. 5 and 6 illustrate another modified form of my invention, having an initially unsecured strip portion, which inthis modification is produced by folding over one upper corner of the bag onto itself, as illustrated by the numeral 25 in Figs. 5 and 6, before th strip l2b is placed over the bag end, thus leaving the corner of the bag available for a filling operation. In this form of the bag, the line of stitches Mb extends straight across the sealing strip l2b, the folding over of the corner 25a obviously preventing the line of stitches Mb from securing the strip [2?) to the folded over corner 25 the folded over comer 25, such corner portion is folded back and placed against one side of the strip portion band may be secured thereto by a row of stitches or if desired, may be secured thereto by a row of staples 25 extending through the strip portion lb and the top margin 01' the bag portion 25, as illustrated in Fig. 6.

The bags herein disclosed, may be used to package finely divided materials such as cement, and the like, and may also be-used to package such materials as rosin, asphalt, and the like, which are'heated and pouredinto the bag in a liquid state. When the latter materials are packed into the bag, it may be convenient practice to support the bags in an upright position in a-frame and to secure the initially unsecured strip portion to the top bag margin, by any of the.methods hereinbefore described, while thebag is thus retained in the frame. My invention provides 'a construction whereby, they strip may be partially secured to the top margin'of the bag, by the bag manufacturer, and shipped to the bag user, who may fill the bag and then secure the initially unsebe performed by the person filling the bag, either by a manual or by an automatic sealing device. The bags herein disclosed are substantially leak-proofdue to the new and novel manner of securing the strip to the top bag margin and may be produced at a relatively low cost.

It will be apparent to those skilled in the art that the invention herein disclosed may be variously used, changed and modified, without departing from the spirit of the invention, or sacrificing the advantages therein, and that the invention herein disclosed is illustrative only and that my invention is not limited thereto.

I claim:

1. A bag comprising a fiat tubular body, including a top end, a strip of material extending along and folded over the top margin thereof along the fold line and extending from one side margin to the opposite side margin with the top margins of .the bag in contact with said fold line, a row of stitches extending through said folded over strip and said bag walls along a line spaced from said fold line and extending from one side margin of the bag partially across the top thereof, thereby constituting a permanent material-containing and holding seam, said-row adapted to be moved away from the top bag margin to permit a bag filling operation and to be secured to the unstitched portion of the bag top after the bag is filled, for the purposes described.

2. A bag comprising a fiat tubular body, including 'a top end, a strip of material extendin along and folded over the top margin thereof along the fold line and extending from one side margin to the opposite side margin with the top margins of the bag in contact with said fold line, a row of stitches extending through said folded over strip and said bag walls along a line spaced from said fold line and extending from one side margin of the bag to a point beyond the center of the bag top margin thereby constituting a permanent material-containing and holding seam,

said row of stitches at said point being ofiset up wardly and continuing along'the strip closely adjacent the fold line thereof to the opposite margin of the bag, and lying wholly beyond the top bag margin, thereby providing .an initially unattached strip portion adjacent one side margin adapted to be moved away from the top bag margin to permit a bag filling operation and to be seamed to the unstitched portion of the bag top after the bag is filled.
