This meeting without overlapping is important in order to provide for joining their tips as presently described and to facilitate engagement of the handles as will be described. For convenient brevity of description the sections 0 0 will be referred to as folded wing sections.

VVhen the blank is converted to set upcondition, the upper tips of said wing section which meet in one plane are secured together and to the side walls I) b by staple fastening e a, this being effected at two opposite sides of the receptacle close to the top thereof. This structure provides what may be conveniently described as thin vertical pockets between the outer surfaces of two of the walls Z) and the inner faces of the overlying wing sections 0, close to the tops of the latter, for interengagement therewith of the handle members presently described. Such intercngagement could not be effected at a high. enough point to avoid risk 'of tilting the receptacle if the acute-angled portions of the Wings 0 overlapped.

Referring now to- Figures 2. and 3, the handle comprises a-flat strip f, preferably of strong paper such as kraft paper, having notches in the edges at each end to form prongs f, said prongs projecting toward the mid-length of the strip. Said strip, in practice, usually bears printed matter ap plied thereto while the strip is flat from end to end, such printing being easily cffected by the same machine as that which dies out the strip with its prongs. When a receptacle has been filled and the top fiaps d closed down, the prongs f at each end of the handle strip are slipped up into the pockets behind the upper corners of the folded and permanently secured wings o as illustrated by Figure 3, and are held there by the frictional grip of the surfaces between which said prongs have been slipped. When. the receptacle is to be emptied, a reverse movement of the ends of thehandle will completely disconnect it. Or, if desired, the handle can be torn away, being of inexpensive paper and not intended for another use.

The receptacle may have one of its to closing flaps provided with a slot {1 and tlfe opposite top flap provided with a bendable metal strip 72, to be interengaged with said slot g to hold the top flaps closed. This lastmentioned feature is not important however, since the handle itself may have a member which holds the top flaps closed, as illustrated by Figures 4 to 9 inclusive. In said Figures 4 to 9 the receptacle itself is the same-as has be'endescribed in connection .with Figures 1, 2".and 3, but omitting the slot 9 and metal strip or tongue h.-

Figures 4 and 5 illustrate a handle comprising a strip 71 having edge slits near each end providing laterally projecting prongs 5, preferably with a strip of bendable metal i enclosed in the aper and extending'from side to side. T e strip 71 has apertured wings i which, when turned up as illustrated by Figure 5, provide a hand grip.

The total length of the strip 2' is such that the prongs t" at its ends are at the right distance apart to cause said strip, when its end prongs are slipped into the pockets under the wing sections 0, to cross the top flaps aZ snugly and hold them down.

In Figures 6 and 7 the structure is 'substantially the same as in Figures 4 and 5, where the same reference characters are employed. The dilference "is that the strip 7?, instead of having laterally projecting prongs, has at each end a tapered prong L, and the strip and its prongs have a strip is of bendable metal enclosed therein or otherwise lcarried thereby, so that when, the prongs areslipped down behind thestap-les c and then bent to hook form as shown in Figures 7, the said strip i holds the flaps (Z closed and the Win s '5 can be em )10 ed as.

a hand grip.

Figures 8 and 9 folded or doubled at a point a little to one side of its mid-length to provide a'lower member Z and an upper member Z. Near the fold said strip is notched in its sidesto provide prongs Z all four of which prongs are to be engaged with the pocket in one of the sides of the receptacle. At the other end of the member Z there aretwo lateral lips Z Z, and/the adjacent end of the member l is notched to provide prongs Z. When this form of attachment is to be applied to a receptacle, the prongs Z are first slipped into engagement with the pocket behind the folded wings at one side of the receptacle, then the free end of the strip member Z is slipped into engagement with the opposite pocket, its lip Z so engaging the fold of one of thewings a that the member Z crosses the top flaps (Z snugly and holds said flaps down. Then the free end of the strip member Z is slipped into engagement with the same pocket over the end of the member Z, and the lower lip Z of the member Z is bent out past the extreme edge of the member Zf, at its end, thereby locking the handle member Z against displacement, as illustrated in Figure 9.

illustrate a paper strip Each form of handle illustrated is economicallymade by a well-known dieing out method, and can easily be printed at the same time, the cutting and proximately 500 a minute. Since the handles are made in flat condition, and when'in use rinting being capable of being effected at t e rate of apcontents, no time'need be wasted by attempting any careful removal of the handle. in

order to lift the flaps d. A pull on the handle will readily tear it away without in any way affecting the receptacle Referring again to Figures 2 and 3, it will be seen that the flap d which is provided with the metal strip h is so formed that its tip is tapered as at (1, said tapered tip, at its Widest portion, practically equalling the length of the slot 9 so that, when the said tip d is pushed fully into the slot and bent back as shown in Figure 3, there can be no relative lateral movement of the flaps which have the said slot and tapered tip. This steadies the box and especially prevents it from flexing to askew condition. Of course 'the boxes illustrated by Figures 4 to 9 inclusive may have the same structure of slot and tapered tip to perform the. abovedescribed functions, illustration thereof being omitted from said Figui-es' 4 to 9, to

avoid an unnecessary complication figures.

.It is important that the metal strip It shall be affixed to the surface of the fla d which is uppermost when said flap is 'rst folded down as illustrated by Figure 2. This is to avoid injury to the fingers of the person who then bends the tip and strip to the condition illustrated by Figure 3. When so of the bent, a'users fingers contact only with thesurface of the paper tip cl, or its edges, which prevent any contact with any portion of the metal strip 71. If such metal strip were tobe exposed to such contact, the edges or other rough, or sharp portions of the strip would be liable to cause injury. Furthermore, when the pail is being carried, the paper material is then so covering the metal strip as to protect the carriers knuckles from any injury due to contact with the top of the box. v Having now described our invention, we claim 1. A paper blank for a seamless receptacle, said blank being rectangular in form with right-angular corner edges and continuous throughout its area and having a pair of angular notches in each edge, each edge beingfstraight from corner to corner excepting for said notches, said blank being creased to provide a bottom section, four wall sections having top-closing flaps, and angular creased sections alternating with the wall sections.

2. A paper receptacle free from slits, consisting of a rectangular sheet folded to proing secured together and to the side walls to provide effective pockets for engagement of ahandle. 1

3. The combination with a paper receptacle having opposite walls composed of over-folded portions providing pockets close to the tops of said walls, of a flat paper handle having end portions removably engaging said pockets.

4. The combination with a paper receptacle having opposite walls composed of over-folded portions providing pockets close to the tops of said walls, of a handle having prongs to removably engage said pockets.

5. The-combination with a paper receptacle having opposite walls composed of over-folded portions providing pockets close to the tops of said walls, of a paper handle having prongs to removably engage said pockets, said handle being normally flat when disengaged from the receptacle.

6. The combination with a receptacle having top-closing members andhaving pockets close to the tops thereof in two of its walls,

of a flexible strip having means to engage said pockets, said engaging meansbeing spaced to cause the strip to hold the top members of the receptacle closed When engaged with said wall pockets.

7. Thecombination with a receptacle having top-closing members and having pockets in two of its walls, of a double flexible strip having means to engage said wall pockets, one member of said strip having itspocket-engaging means spaced to cause said member to hold the top members of the receptacle closed when engaged with said wall pockets, the other member of said strip having its pocket-engaging means spaced farther apart to enable it to beemployed as a handle. 8. A normally flat paper handle for a receptacle, said handle comprising one portion having integral prong members to engage with portions of the receptacle and having another portion integral therewith and formed to provide a hand grip portion.

In testimony whereof'we have afiixed our signatures.
