6 Claims;

This invention "relates 'to a paper bag having a, flap provided with a reinforced locking tongue' and providingan arrangement whereby a ticket, memorandum or the like, folded in strip form, maybe s'ecuredt'o the bag without the need for using "a c ommonpin or the like with their at-- tendant disadvantages.

one objectof the invention is to provide a paper bagjirhich maybe'manufactured alt acos't substantially the same as a conventional paper ba':"yet*which will havethe advantages indicated, naelina reinforced flap locking tongue and an a an ement for securing thetickt or mem'm ran stripofthelike tbthe'bag through using theiio'ristriitionof the bag itself. Another object lsto provide for securing the describedstrip tetne-bas'insucn away that oneor'both sides of the strip are visible.

siiecificexamplesof'the invention incorporated into an otherwise conventional fiat paper-"bag, are f-lustr'ate'd by the accompanying drawings in which:

Fig. 13 is similarto Fig. 7 excepting that it showsthe second example in the form in which it'is usually sold 'andpri'or to mining Many of the parts.

Referring to the first example shown by Figfires i through dtne'inustr'atea bag has a front wen *1 and a tack-wan *2 which are mutually osposea andriefine a mouth, a'flap 3 extending nomthe Beck Wall 2 and being "foldable "down 2 over the other or front wall I to close the bag mouth.

Beth bag Walls are severed. along an upwardly facing u-shaped line 4 todefine upwardly swingi'rigtongues 5 which When displaced by being folded, along their fold ii'nes 6, provide the bag walls with an opening.

The flap 3 includes the longitudinal seam 1 of the bag wall 2 and throughout the flap this is left'disconnectecl, by interrupting the usual lines of "adhesive, so that the flap includes a; right-hand section, numbered-3, and a lei't hand section numbered 3a. This left-hand section has a transverse or horizontal fold line 8 on \vhiohthefiap section 311 folds doubled on itself, the fiapparts being long enough so that the halo section 3a overlaps the opening formed by fold ing and displacing of the wall tonguesfi.

As shown by Fig. 3 in particular, the flap section to is severedalong lines 2) defining a foldable tongue ID, at the flap fold lineB, when the fiap section fid'is folded double on this line. This flap 1'9 is located, by proper placement of the severance lines 9, to pass through the described Wall opening when-the tongue I0 is folded. The flap tongue lines of severance!) comprise substantially C-=lile shapes spaced transversely respecting theflapand facing each other and. forming the tongue [0 into a Winged tongue wider than the described wall opening when the flap section Sa'is doubled on its fold line 8. V

In usi'ngthis bag themerchandise or the like is placed in the Bag while the latter is in the Condition shownby Fig. 3. If desired the righthand flapsection 3 may be folded down inside of the bag mouth asshown by Fig. 2. In any event the flap section 312 is folded'double on its fold line 8 so that the linesof severance g definethe tongue i0. Note that this tongue is reinforced without the use of reinforcing patches or the like, because the tongue is formed from a double thickness ofthe flap section Dis lacement of the tongues 5' in either direction forms the bag wan opening, and the tongue I G may then be thrust through this opening so that its Wing-like transverseends snap on the otherside of the bagand lock th tongue it against Withdrawal. As shown by Fig. 6 a single push of the tohgueit causes this tongue to displace the Wall tongues 5 and effect the locking actiona This is not only simple and convenient but ithas the advantage that the resiliency of the tongues 5 holds down the tongue l-G so that its wings morepositively retain their locked relatiofisliip.

All of the above features are provided without adding anything to what may be an otherwise conventional fiat paper bag. Although the flap locking tongue is reinforced, no extra pieces of paper in the form of patches or the like are required. Thus this invention achieves its stated objectives in so far as the provision of a reinforced fiap locking tongue without increase in cost, is concerned.

GOlIlg now to the second example, shown by Figures 7 through 13, it will next become apparent how the principles of the invention provides for retaining a ticket strip or the like to the bag so that both sides of the strip are visible.

In so far as is possible the same numerals are applied to corresponding parts, of this second example, as were used in connection with the first example. The letter a is added as required for identification purposes.

It will be noted that the flap, necessarily marked 3b, is formed as a single flap by reason of the longitudinal bag seam being secured throughout the fiap. The tongue 5a is shifted to the center of the bag walls by appropriate placement of the lines of severance 4a. The tongue lUa is correspondingly shifted in the same fashion so that it may be passed through the opening formed by displacement of the tongue 5a. In both examples the tongues Iii and Illa respectively, of course, hinge on their own fold lines, indicated at H in Fig. 3 and Ila in Fig. 13 in the case of the first and second examples respectively.

Coming now to the ticket. This, or any other memorandum or piece of paper, is folded into the form of a strip l2 of any desired length providing it is longer than the width of the tongue [a. Thus folded, the ticket is woven through the lines of severance 9a of the tongue 16a so that, with the flap opened, the strip ends are on the inside of the flap while the central portion of the strip is on the outside of the part that forms the tongue Illa. Furthermore, the strip I2 is arranged with its upper edge flush with the flap fold line 8a so that when the flap is folded double on itself this strip is nested in the flap fold line and inside of the doubled flap. Then, with this arrangement, the previously described operations are performed. In other words, the tongue [0a, formed by folding of the flap, is thrust through the opening formed by displacement of the tongues a. Thus the bag flap is locked shut with the ticket strip secured to the bag flap and exposed at the front of the bag because the ticket strip spans between the lines of severance 9a as is shown by Fig. 7.

As to the opposite side of the ticket strip, this also is exposed at the back of the bag when the tongue lfla is folded upwardly as shown by Fig. 8. In the first example the tongues 5 were swung with the tongue II], but in this second example the tongues 5a are shown as being first folded up against the front wall Ia of the bag, the tongue Illa then being thrust through the resulting opening to the back of the bag and folded upwardly as described. The finished result has the appearance of a bag provided with back and front windows through which the ticket strip is visible through both directions, both sides of the strip being exposed throughout the strips central portion. The cross sections, particularly Fig. 11, help to understand the described arrangement.

It can now be seen that the described bag construction attains all of the objectives of the invention. Whether the described construction is used simply as a reinforced flap lock or also to retain the ticket strip, there is no need for adding parts to the conventional bag construction or otherwise altering its manufacture excepting for the provision of the appropriately placed lines of severance. These lines may be made by the use of a suitable die cutter roller set used in conjunction with the usual automatic paper bag making machine. This does not add appreciably to the cost of the final product.
