` 2 claims. (ci. 22948) Among the principal objects which the present invention has in view are: To provide a serviceable closure lock for paper bagsr mostly used `by women' when shopping; to facilitate the operation of closing such bags in service; and to reinforce the handle feature of the construction.

Drawings Figure 1 is an extended view of the fragment of paper or strip of which 4these bags are manufactured showing the complementary structural features which avoids any Waste of material in separating the paper strip into bag elements, the broken lines shown in the drawings being used to indicate score or bend lines for folding into envelope shape.

Figure 2 is a detailed view on enlarged scale showing in detailthe structure forming the major portion of the handle portion of the bag.

Figure 3 is a detailed view on enlarged s'cale showing a fragment of the bag,` the parts being arranged as the result of the first step in closing a bag.

Figure 4. is a detailed view showing the parts of the lock disposed as in Figure 3, the section being taken on the line tin Figure 3.

Figure 5 is a detailed view on enlarged scale showing the handle features in the closed position of the bag.

Figure 6 is a sectional view showing the arrangement of the'parts when disposed as shown in Figure 5, the section being taken on the line 6 6 in Figure 5.

Description One of the main objects sought in the present invention is that of preventing the accidental opening of "pags, or the separation of the front 9 from the back It, of the character herein set forth, when filled. It has been found that the goods or articles disposed in the bag exert a latveral or side pressure on the sides of the bag which succeeds in separating the same at the flap opening of the bag. It is to restrain this action that the blanks such as shown in Figure 1 are provided at the one end with `a slit Il and at the l other end with a tongue I2. 'Ihe slit II is coincident with the folding line of the cover iiap I3. The folding line in the drawings in Figure 1 is indicated in dotted lines and by the numeral I4.

When the bag is closed, the operator first inserts the tongue I2 through the slit II, as seen best in Figures 3 and 4 of the drawings. The next step in the operation of closing the bag is to fold the flap I3 down into closed position, bending the same on the folding line I4, which as explained, is coincident with the slit II.

It will be noted that the closure flap I 3 has formed thereina cut-out portion which corresponds in shape to the tongue I2, and in fact is formed in cutting the tongue I2 when severing the blank for the bag from the continuous strip from which it is formed. It will also be noted that that portion of the closure flap indicated by the nurneral I6 has width equal to the distance between the slit II and the top Il of the finger opening I8.

'Ihe direct result of the arrangement just above described is that when the iiap I3 is overturned on the body of the bag, the portion Iii is superimposed on the portion I9 of the side of the bag carrying the tongue I2.

With the parts arranged as above described,

. the handle lock flap 2U is pushed through the finger opening Iii and upturned against the portion It holding it securely against the portion I9, especially when the bag is ybeing carried in the hand of the purchaser. l

It will be noted especially, as seen in Figures 3` and 5 of the drawings, that the flap 2li is purposely constructed withv slightly greater length than the finger opening I8, and has formed at the ends thereof, barbs 2i, the object of which is to bear against the portions of the bag below the top of the nger opening I8 to hold the flap 20 in 4upright or service position such as shown in Figlires-5 and 6 of the drawings.

When the parts above described are constructed and arranged as described and shown in the accompanying drawings, it will be seen that unless the handle lock flap 2li is dislodged from engagement with the portion i6 of the closure flap I3, the closure iiap cannot be opened up. At the same time it will be noted that any lateral pressure on the closure i'lap is counteracted by the tongue I2 which is held by and within the slit I I. The cooperation of the tongue I2 and the barbs 2i effectively prevent any accidental opening of the closure ap I3.

It will be observed by reference to Figure 1 of the drawings that the blank therein shown illustrates how the opposite ends of the blank are complementary. It also shows that in order to provide an emcient length for the exposed portion of the closure flap, the sections thereof at both sides of the slit I I are widened with the effect, as

'seen best in Figure 5 of the drawings, where the To reinforce the structure just described, thel blank is provided with

patch sections

22 and 23. As seen in the drawings. the patch section 22 is constructed to present all of the features above described with reference to the locking members. The patch section 23 in a like manner is constructed to have all of the structural features described above with reference to the disposition of the tongue I 2 and finger opening I8.

In Figure 1 of the drawings, a score line 24 is shown as being that on which the blank is folded in the formation of the bag. The bag shown is of the side closure type and preferably that having overturned side edges 25 which when provided with suitable adhesive, structurally close and complete the bag.

While the present disclosure relates to bags of the side seam type and bags having reinforcing patches, it will be understood that I do not wish to be limited to structures embodying these features.

Center-seemed bags could be substituted for the side-seemed bags and both could, without altering the scope of the invention, be used with or Without reinforcing patches.

I claim:

1. A bag as characterized having front and back portions and a closure flap extended from the-front body portion of said bag, said flap having an elongated narrow central portion adapted to, in conjunction with corresponding portions of said front and back, form a carrying handle for said bag, said carrying handle comprising elongated narrow sections of said front and back portions adjacent the closing bend of said flap, said handle sections in said front and back being formed by cutting elongated finger openings therein, an extension from said front portion resulting from the formation of the finger opening therein, said extension being adapted to fold through said nger openings to cover said narrow portion of said flap, a tongue formed on the opening edge of said back for engaging said front portion in holding relation thereto, and a slit formed in said front portion at the bending line of said flap to receive said tongue.

2. A bag as characterized having front and back portions and a closure flap extended from the front body portion of said bag, said iiap having an elongated narrow central portion adapted to, in conjunction with corresponding portions oi. said front and back, form a carrying handle for said bag, said carrying handle comprising elongated narrow sections of said front and baci; portions adjacent the closing bend of said ap, said handle sections in said front and baci: being formed by cutting elongated finger openings therein, an extension from said front portion resulting from the formation of the finger opening therein, said extension being adapted to fold through said finger openings to cover said narrow portion of said flap, a tongue formed on the opening edge of said back for engaging said front portion in holding relation thereto, and a slit formed in said front portion at the bending line of said ap to receive said tongue, said tongue being cut in the bag-forming blank from the adjacent bag-iorming section to shape said elongated narrow central portion of said flap.
