Claims. (01.150 45) This invention relates to improvements in closures for bags, pocketbooks and'othr containers, and has for its principal object the provision of aclosu re for bags or the likewhich wm'have many of the merits and advantages of the socalled zipper closures, but which will be simpler in const'iuction and inexpensive to manufacture.

Another object of this invention is to provide aneffi cient bag closure which can be made lalf ?fposition shown in Fig. 5, the bars lzand l3 can be pivotally rriov'd in relation to' each othr so as m pe'r'r'nit access to the cements of;-the' bag. By nioving'the slider toward the open end-of the big, thejb ars iana I3fare brought-into closer 1y of hon-metallic material which will be easy o p ate a d w i li w en t w t d cu l T Further objects of the invention will be ap parent from the specif cation and drawing, in

Fig, 1 is a front elevational view of a bag; 2 is a perspective view of the -bag, with the slidepushed back, the bag ready to be; opened; Fig. 3 is a section on the line 3 -3 of, 2; Fig. 4 is a fragmental detail of the endsof, the frame;

Fig. 5 is a section on the line 5-5 of Fig. 4 and Fig. 6 is a perspective detail of the slide piece. The numeral 10 indicates a bag to which the closure is fastened by means of sewing or staples indicated as l8. The numerals l2 and I3 are the longitudinal frames or bars which constitute the principal body of the closure. At the meeting edges of the bars l2 and I3, the bar l2 has a locking projection or flange l4 fitting into a. complementary groove IS in the frame l3. It is an advantage if the angle of the projection I4 is somewhat broader than the angle of the groove or concavity l 5 so that when the bars are pressed toward each other, the pressure of the bar [2 having the projection M will tend to look into the depression or groove l5 of the bar l3.

On the top of the bars or frames l2 and I3 respectively are grooves l6 and I! in which the slider 2! operates. The grooves l6 and I! have widened portions at their bases l6a and Ha respectively in which the studs 25 and 26 having the projections 25a and 26a of the slider 2| fit, the numeral 22 indicating the angular body of the slider 2| and the numeral 23 the finger piece of said slider.

The numeral 24 represents the open side of the bag to permit the bag to be opened and the ends of the bars l2 and I3 to be widely separated from each other. The numerals l9 and 20 indicate the terminals of the grooves l6 and I1 and it will be seen that when theslider is in the "The longitudinal framesfor'bars 12am I3 ca n pretrably be'made of a synthetic plastic or other flexible material, as a certain elasticity 'wouldfbe an advantage for certain uses'of this type of closurel f e bars or frames I2 and 13 can be madjeoi meta-l; howeverfiffdesired. It" is apparent that changes maybe maderin slider Z'IIi s ai-Q" the positiohishowniindottedlines 't hout departing from the spirit'of my invention.

It should also be noted that the tips of the slider and the grooves in which'th'e slider moves are so iashionedjthat the "slider cannot'b'e lifted from the closure but is 'permanently'attached thereto in slidable relation:
