To all whom it may concern:
-' Be it known that 1, JOHN P. Mannnn i,
' a citizen of the United-States, residing at New York city, in the county of Kmgs and State of New York, have invented new and useful Improvements in Car-tons, of which i the following is a specification.
My inventlon relates to cartons and particularly to. cartons for packing perishable articles held out of contact 'with each other.
An object of my invention is to provide a carton having a transverse shelf positively 4 held against movement and adapted to hold a plurality of fragile or perishable articles out of contact with each other-and to prevent them from moving in the carton during shipment.
A further object is to provide a carton made of a single sheet and having a transverse shelf positively held in position when the carton is closed.
I also provide a carton made of one piece and having a transverse shelf, which can be readily knocked down and shipped in fiat condition and which at the same time can be very easily and rapidly folded into position to receive articles therein.
My container also dispenses entirely with tongue and slot connections for its parts but is substantial and strong when .in folded position and not liable to be deranged or collapsed.
Cartons formerly produced for a similar I purpose have commonly been composed of ready for folding,
a plurallty of parts making assembling more diflicult and involving a danger 0 loss of parts. Others have been complicated in structure, requiring numerous folding processes, the time consumed in assembling them, making their use expensive in actual practice. Others are so constructed that upon opening them' they practically collapse losing their box-like structure. I
I have made the invention herein disclosed with the object of avoiding thesedifliculties and of producing a carton that will be cheap to manufacture and'assemble, easy to ship and strong in use, oneillustration of which is set forth in the following specification and disclosed in the accompanying drawings in which:
Figure 1, is a plan-View of the blank before folding, Fig. 2, is a perspective view of the carton I Fig. 3, is a similar View partly folded,
F g. 4, is a transverse cross section,
F g. 5, s a longltud inal cross sectipn, and
-F 1g. 6, 1s a perspectlve view of the folded carton.
The carton is composed of ends, 1 and 2, and s1des-3 and 4, lap 5 being attached to one end of side 4 and serving as means for permanently coniectin the end of side 4 to end 1 by gluing. nds 1 and 2 each have upper and lower flaps 6 -for folding from one edge of side 4 isomer 7 having tucking flap 8; and extending from the other said side 4 is bottom 9 havingsimilar tucking fiap 10. v Extending from the upper edge of side 3 (the lower edge in the blank; shown in Fig. 1) is the suspendmg flap 11 continuous therewith, which is extended to form shelf 12, having at its farther edge flap 13 and at its side edges flaps l land 15. Shelf 12 may be apertured in suitable 'manner to accommodate the articles intended to be carried by the carton. In the illustrated example it is pierced by a series of circular apertures 16 With the carton I inwardly in the usual manner. Extending each having radial slots 17 adapted to receive the stem of an electric light bulb. If desired the fold lines between side 3 and flap 11," and between flap '11 and shelf 12, may be slitted, as at 18, to facilitate folding along said lines.
In practice the box is first assembled by gluing lap 5 to end 1, shaping the box as shown in Fig. 2. In this form the box may be collapsed by diagonally flattening it and is shipped in this form, there being no parts to lose and no portions likely to be broken off, as is the case where there are several arts to a carton or where tongues are used. Vhen received by the purchaser it is folded into shape. This is preferably done by inserting the lower edge of side 3 (the carton being in the form shown in Fig. 2') in a kerf in a block of wood slightly, shorter than the box, the depth of the kerf being approximately equal tn the distance of the shelf above the bottom of the carton. The
- operator then folds flaps 14 and 15 inward andflap 13 outward with one movement. While the box is held in this position the shelf is forced downwardly into the body of the carton to the position shown in Fig. 3, (the bottom of the carton however beingengaged, thus closing the "bottom of thebox. Obviously other methods of folding may be used but this method is the preferred one.
1 It is to be noted that flaps 14 and 15 are exactly equal in depth to the distance between shelf 12 and the bottom of the carton while flaps 11 and 13 are exactly equal in ,depth to the distance of said shelf from the top of the carton. When the carton is in v closed position these flapswill butt against the top and bottom of. the carton respectively and the shelf will not only "be supported along all its sides but will be positively prevented from moving either upwardly or downwardly. By varying the depth of said shelf'flaps, the distance ofthe shelf from the top and bottom of the carton can be varied and its angle in relation thereto can also be determined if it be'considered desirable to have the shelf tilted rather than parallel to the top and bottom.
While I have'described the shelf as integral with thevrestof the carton it may be separate therefrom and either permanently attached thereto or entirely free and separate.
While I have described the preferred form of my invention it is obvious that many changes in details may be made without departing from the spirit of my invention as covered in the following claims;
It will be apparent, for instance, that flaps 14 and 15 may, with equal facility, be. up ward and flap 13 downward, as the shelf will be positively supported by this arrangement as well as in the form above described. Furthermore, while I have described one part as the top and anotheras the bottom, it will 'be apparent that either may be used as the top. 7 I
What I claim is:
1; A carton includingside walls formed from a single continuous strip of material v and having their upper edges on substantially the same plane, a bottom, a top, an
intermediate shelf adapted to lie transversely of the carton between said top and bottom when in closed position, means for hingedly connecting one edge of the shelf to one side of the' carton' with said edge lo-- cated against said side and below the upper wall edge thereof, an integral 'fiap' carried by said shelf and extending downwardly intdengagement with .the carton bottom, and
m an integral flap carried by said shelf and extending upwardly in to engagementwith the carton top the construction being such that said shelf is held positively against both upward and downward movement by the engagement of said extensions with the top and bottom of the carton, when closed, and the carton may be collapsed diagonally by folding said shelf outwardly about saidhinged connection.
2. A carton made from a material, including side walls formed from av single continuous strip and having their upper edges on substantially the same plane,
single sheet of M a bottom, a top, an intermediate shelf adapted to lie transversely of the carton between said top and bottom when in closed position,
a hinge strip connecting the upper edge of a side wall with the adjacent edge of the shelf located against the wallbelowsaid wall edge when in closed position, an integral flap carried by said shelf and extendmg downwardly into engagement with the carton bottom, and an integral fl ap carried by said shelf and extending upwardly into engagement with the carton top, v the construction being such that said shelf is held positively against both upward and downward movement by the engagement of said extensions with the top and bottom of the v carton, when closed, and the carton'may be collapsed diagonally by folding said shelf outwardly about said hinged connection.
3.v A carton made from a single sheet of material and including side walls formed from a single continuous strip, having their upper edges on substantially the same plane," a bottom element hingedly connected to -a side wall, a top element hinged to a side wall, an intermediate shelf adapted to :lie. transversely of the carton between said top and bottom elements when in closed position, a hinge strip connecting the upper edge of a side wall with the adjacent edge of the shelf located against the wall below said wall edge when in closed position, flaps carried by the edges of the shelf adjacent the hinged edge thereof and extending along the sides of the carton in the same direction into engagement with one of saidelements,'- and a flap carried by the edge of the shelf opposite to the hingededge and extending along the adjacent side of. the carton'in the opposite direction into engagement with the other element, the construction being such that said fiapsand hinge-strip maintain the shelf against vertical movement when the carton is closed, and said carton may be collapsed diagonally by extending said-shelf,
