COLLAPSIBLE OR KNOCKDOWN BOX.
Specification of Letters Patent.
Patented Dec. 1, 1914.
Application filed May 31, 1913. Serial No. 770,921.
To all whom it may concern:
Be it known that I, J osnrn \V. Weiss, a citizen of the United States, and a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Collapsible or Knockdown Boxes, of which the following is a specification.
This invention relates to collapsible or knockdown boxes, particularly to the type known as the slotted carton and forms a division of my co-pending application Serial Number 726,003. In this last mentioned ap plication, various embodiments were disi closed and broadly claimed of a reinforced collapsible box in which a fold was formed out of the material of the box between the sides and the end flaps. The more specific claims were directed to an integral construction wherein the entire box, including the sides, folds and end flaps were made of one single piece of material.
The invention in the present application is directed more particularly to the divided construction in which the sides and end flaps are formed of separate pieces'fastened together in a suitable manner and has several distinct advantages peculiar to the divided construction, 'among which may be mentioned, ease of manufacture and provision in certain forms for covering the slits at the junction of the folds which are incidental to the integral construction described in said application.
In the accompanying drawings illustrating the preferred embodiments of this invention, Figure 1 is a perspective view illustrating one form of the divided construction, the flaps being shown as extended, as in the collapsed position in which the box is stored. Fig. 2 is a fragmental sectional view of the form illustrated in Fig. 1, showing the folds formed as a continuation of the flaps. Fig. 3 is a fragmental sectional view similar to Fig. 2, illustrating a modified form in which the folds extend partly from the sides and partly from the flaps. Fig. 41: is a fragmental sectional view illustrating a further modified form of fold. Fig. 5 is a fragmental perspective view illustrating a form in which the flaps are connected together to conceal the slitted edges which may be used in connection with the various forms of folds illustrated.
The various forms of collapsible boxes in which the present invention is embodied may all be made of fibrous material and comprise sides, end flaps separate from the sldes for closing the ends of the box, and a strengthening fold adjacent to the junction of the sides and end flaps which may be formed either entirely as a continuation of the flaps or partly as a continuation of the flaps and a continuation of the sides, these folds being in every case attached to the sides and forming reinforcing means for the sides and also as means for spacing the sides proper from the surface on which the box is supported.
Referring in detail to the form illustrated 1n Figs. 1 and 2, the box has sides 10 which may be collapsed at their flexible edges 11 which may be formed in any suitable manner as by scoring the blank previous to its being set up. The flaps 12, constitutin the lid or closure for the end of the boxfiiave portions 13 thereof overlapping the end edges of the sides and are attached thereto by suitable means such as staples l-l. To reinforce the box at the edges and to provide a substantial projection which will serve to space the body of the box from the supporting surface, the flap members 12 are formed with a fold 15 extending preferably under the overlapping portion 13, previously described. T 1e sides of the box may thus be made of one piece and the flaps may be made out of one or more separate pieces which may be readily attached to the sides without necessitating any slitting of the material of the sides themselves. Also these flaps, by reason of being separate from the body of the box may be made of small strips of material which otherwise would go to waste and thus results in a further considerable saving in the cost of manufacture.
In the modified form illustrated in Fig. 3, the sides 20 have the overturned portions or folds 21 and the flaps 22 have the overlapping portions 23 provided with turnedunder fold 24 in alinement with the overturned portion or fold 21.. In this form, two sets of staples 25 and 26 may be used to attach both the portions 24 and 21. firmly to the sides. A certain advantage arises in this form by reason of the interlocking of the flaps and sides by the abutting of the folds 24 and 21.
In the modified form illustrated in Fig. 4, the sides 30 have the overturned portion or told 31 and the flaps 33 have the overlapping portion 33 which extends over the sides substantially in alinement with the inwardly extending edge of-the' fold 31. Among the advantages of this form may be mentioned the fact that the flap portion may be formed of a simple, fiat sheet without necessitating the folding of the same. This' may prove of advantage in certain forms of material.
In. the constructionillustrated in Fig. 5, the flap portions 42 may be formed out of a single sheet of material having a portion or band 43 overlapping past the end edges .4. However, it may in some cases also be used to advantage in the first two forms illustrated in Figs. 1 to 8.
It will thus be seen that I have provided an improved collapsible box which is reinforced so as to safely sustain rough handling which the ordinary box of this character cannot sustain, which improved box fastened thereto to form therewith a memis also readily and cheaply manufactured and is capable of utilizing for certain of its parts, odd pieces of material which otherwise would go to waste.
Having thus described my invention, I claim- 1. A collapsible box of fibrous material having sides, and end flaps formed in a separate piece from said sides and permanently her which may be handled as a unit at all times, there'being reinforcin folds at the junction of the flaps and si es, said "folds forming projecting strengthening ridges at the edges of the box so as to space the sides from the supporting surface upon which the box may rest, and means for permanently attaching said folds to said sides.
2. A collapsible box having quadrilateral sides, end flaps formed in a separate piece having portions thereof projecting .over the edges of the sides, there being a strengthening fold between said overlapping portions and sides, and means for permanently'attaching said overlapping portions to the sides, the entire box, including sides, flaps and folds, forming a unitary member.
3. A collapsible box formed of fibrous material comprising quadrilateral sides and a closure for the box formed in a separate piece comprising flaps and a continuous band projecting from said naps and passing entirely around the end of the box, there being a reinforcing fold between said band and sides, said band and reinforcing fold forming a continuous ridge about the end of the box adapted to space the sides from the supporting surface, and means for permanently attaching to each other the overlapping portions of the end member and sides, the entire box, including sides, flaps and folds, forming a unitary member.
Signed at New York city, in the county of New York, and State of New York, this 29th day of May A. D. 1913.
