Patented Sept. 30, 1947 UNITED STATES PATENT OFFICE 2,428,227 BAG AND oLoSURE THEREF-oa Nathan .Kase, .Binghamton, .N. Application November 6, 1943, Serial No. 5691220 .1 Claim.

1 This invention relates to improvements in bags of the kind in which the walls of the mouth of the bag are made of fabric, leather or other flexible material.

The primary object of the invention resides in a bag which is self looking to eliminate the use of frames, slide fasteners, catches, and other extraneous closure devices.

Another feature of the invention relates to a bag in which the free top edges along the opposed side walls of the bag are provided with reinforced beads for releasable interlocking engagement when the bag is in closed position and which interlocking is suiiicient to prevent the bag from accidentally opening during ordinary handling of the same, but an operator may by a slight flexing of the beaded edges, cause the same to be readily disengaged when access to the interior of the bag is desired.

A further feature of the invention is the provision of a simple and inexpensive bag closure construction which may be embodied in coin purses, cosmetic bags, tobacco pouches and other like articles having an opening to be closed.

Other novel features of the invention will become apparent as the following specification is read in conjunction with the accompanying drawing, in which:

Figure 1 is a front elevational view of the invention embodied in a cosmetic bag shown in closed position, a portion of the front wall being broken away.

Figure 2 is an end elevational view illustrating the bag in open position in dotted lines.

Figure 3 is an enlarged vertical transverse sectional view on the line 33 of Figure 1.

Figure 4 is a front elevational view of the bag turned inside-out.

Referring to the drawing by reference characters, the numeral l designates the improved bag in its entirety which includes a bag body ll constructed of flexible material such as fabric, leather, rubberized material, or the like. The bag body H is constructed of an outer thickness of flexible material l2 and an identically shaped thickness of inner lining material I3. The front wall M of the bag body has an arcuate shaped top edge l5 bound by a strip of binding tape l6 stitched to the edge l5 as at l! to provide a tubular covering for a flexible reinforcing element is in the form of a length of still stranded or solid cord which is round in cross section as best illustrated in Figure 3. The reinforced top edge of the front wall defines an inwardly facing bead A for interlocking engagement with a com- 2 panion inwardly extending bead B provided on the top edge of the rear wall i9 and which will now be specifically described. I

The top edge 2 9 of the rear wall 19 extends beyond the plane of the edge l5 of the front wall and is likewise convexly curved and has a length of binding tape 21 stitched thereto as at 2 2 for enclosing a flexible reinforcing element 23 similar to the reinforcing element 18. The ends of the edges 15 and 20 are so cut as to provide a clearance between the end portions of the beads A and B when the bag is closed, while themidportions thereof are-disposed relative to each other to require the bead Ato be forcibly pushed to a position inwardly of the bead B into interlocking engagement.

The beads A and B provide a snap-frame for the opening to the bag and they are secured together adjacent their ends by stitching 23 and which points of stitching provide a hinge connection between the beads and the upper portion of the front and rear walls to enable the said portions to be swung to an open and closed position as illustrated in full and dotted lines in Figure 2. When the bag is in closed position the entire length of the bead B overlaps the bead A but at the mid-portions, the beads A and B definitely interlock for the said mid-portions are disposed one in the path of pivotal closing movement of the other. The reinforcing elements l8 and 23 are sufliciently stiff when bowed to provide ticles placed in the bag from accidentally slipping therebetween during the ordinary handling of the bag.

- The bag H! is made inside out as illustrated in Figure 4, with the lining side l3 face out. The material or thicknesses of material from which the bag is constructed is folded upon itself along the bottom fold 24 while the side edges are stitched together by the lines of stitching 23, the top terminal ends of which hingedly connect the ends of beads A and B together. The tubular bindings l6 and 2| and the reinforcing elements l3 and 23' are applied while the bag is inside out and the same project beyond the stitched side edges, however, when the finished bag is reversed, that is, turned right side out, the top corner edges of the bag are pulled inwardly as illustrated best in Figure 1, whereupon the extending ends of the beads A and B are concealed within the body of the bag.

. For preventing accidental disconnecting of the interlocking beads A and B when bulky ar= ticles are placed in the bag, I provide an auxiliary fastening means in the form of a flap 25 secured at the mid portion of the top of the-rear wall l9 by the stitching 22. The flap is provided with a female snap fastener element 26 which interlocks with a male snap fastener element 21 secured to the exterior of the front wall [4. The flap 25 is folded forwardly and downwardly over the interlocked portions of the beads A and B and secured by engaging the female fastener element 26 with the male fastener element 27. The flap 25 tightly fits over the beads and prevents accidental disengagement thereof by bulky articles placed within the bag which might cause the walls of the bag to unduly spread.

While I have shown and described what I consider to be the preferred embodiment of my invention, I wish it to be understood that such changes in design and details of construction as come within the scope of the appended claims may be resorted to if desired without departing from the spirit of the invention.

Having thus described the inventin, what I claim as new and desire to secure by Letters Patent of the United States is:

A bag comprising a flexible body having an open mouth, the top of which is defined by a pair of convexly curved top edges, flexible solid round beads provided on the opposed edges of the walls of the mouth and conforming to the lengthwise shape thereof and extending inwardly in confronting relation, each of said beads including a fabric tube and a length of cord enclosed within said tube and extending the length thereof, the ends of the opposed beads being connected together by stitching to provide a hinge connection between the opposed walls of the mouth, said beads being offset vertically relative to each other, the opposed end portions of the beads beyond the hinges being clear of each other and the intermediate portions thereof between the hinges overlapping when brought together to closed relation, whereby the friction between the opposed intermediate portions will efiect an interlocking of the intermediate portions to secure the walls of the mouth of the bag closed, with the end portions of the beads in close overlying relation.
