HERMAN L. GREVE, or NewV YORK, N. Y.
Specification of Letters Patent.
Patented Apr. '7, 1914.
Application filed April 17, 1913. Serial No. 761,713.
To all whom lizfmay concern Be it known that I, HERMAN L. GREVE, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Mailing-Wrappers, of which the following is a specification.
This invention relates to mailing'wrappers, particularly such as are suitable 'for mailing photographs, magazines,bo oks" or similar articles which must be mailed flat.
The principal object of this invention is to rovide a mailing wrapper of this character 1n which the' flaps may be readily and se curely fastened, avoiding the possibility of accident-al unfastening.
Another object is tov provide a wrapper which may readily be opened without tearing the aps. Y
A further object is to provide a construction whereby the side and Aend flaps are readily interlocked and also as readily un'- locked from each other.
Still further objects and advantages will appear more' fully from the detailed description and the features of novelty will be particularly pointed out in the claims.
Referring to the drawings illustrating this invention, Figure 1 is a perspective view of my improved wrapper,'showin`g one of the fasteners in locked and the other in unlocked position. Fig. 2 is a development on a reduced scale of the construction illustrated in Fig. 1. Figs. 3 and 4 are respectively a plan view and a development of a modified form showing the projecting ends of the flaps formed with inclined edges. Figs. 5 and 6 are respectively a plan view and a developmentof a form in which the projecting ends of the flaps are formed with inwardly inclined edges in an opposite direction from the form illustrated in Figs. 3 and 4. Figs. 7 and 8 are respectively a plan viewand a development of a modified form in which the flaps are each formed with a. plurality of notches. Figs. 9 and 10 are perspective views illustrating a further modified form of box which can be made lof a stiff material such as corrugated board or the like.
The invention is more particularly adapt i ed for a wrapper which ywhen set up forms a box-like construction, the entire wrapper being preferably ofv a single piece of comparatively stiff though somewhat flexible material such as pasteboard or the like. The wrapper accordingly consists of a bottom portion, side portions' constituting walls and side and end flaps extending from the walls. These side flaps are preferably formed with notches at their adjacent edges dividing the flaps into a plurality of`sect-i0ns which respectively overlie and underlie one another resulting in an interlocked construction when the box is set up. The ends of each of the flap sections are formed with projections which are held down to the end flaps underlying the side flaps by means of suitable fasteners which are preferably attached to the end flaps and adapted to be turned over these end projections.A
Referring in detail to the drawings, particularly to Figs. l and 2, the wrapper consists of a bottom 10, side walls 11 and 12 having side flaps. 13 and 14 forming a c0ntinuation thereof, end walls 15 and 16, and end flaps 17 and 18 forming a continuation of the end walls. Theside flaps 13 and 14 are formed preferably with V shaped notches 19 .and 20, dividing the flaps into sections 21 and 22, and 23 and 24. When the box is set up, the meeting flaps 13 and 14 are interlocked by interengagement at their notches 19 and 20, the flap sections of the opposing flaps overlapping each other as clearly illustrated in Fig. 1. The notches are preferably cut to a depth such that the apices of the notches register and abut when the flaps are so interlocked.
To further secure the side flaps to each other and also to interlock with the end flaps, I form the ends of the flap sections 21, 22, 23 and 24 with projecting portions 25, 26, 27 and 28 registering over one another and attach these projecting portions to the end flaps. Preferably, the fastening means consists of a strip of sheet metal 29 secured to each of the end flaps 17 and 18 in any suitable manner, as by tongues 30 which extend through slits. formed in the flaps. The strip has end portions 31 which are positioned so that they can be bent over the projecting ends 25, 26, 27 and 28 as illustrated at the top of Fi 1, in connection with the flap 17. When t ese end portions 31 are so bent over, the ends 25, 26, 27 and 28, of the. side fiaps are locked to each other and also=to the end flaps, thus securely 'fastening the parts together. The end ortions 31 are preferably formed with inclined l lying closely adjacent to the apices of the notches formed by the projections 25, 26, 27' and 28 and the inclined edges 33. In this way, Alongitudinal motion of the iiaps relatively to each other is eifect-ually prevented.
In the modified constructions illust-rated in Figs. 3 and 4;, the projections 25, 26, etc., of the side flaps are formed with outwardly inclined side walls 50 over which are turned the end portions 31a of the fasteners. These fasteners may be formed with an inclined notch, score, or perforation 51 corresponding tothe inclination of the Walls50, thus causing the end portions 31 to properly bend over these walls. The fasteners 29a may be formed with extensions 52 which extend over the end walls 15et and 16a and are fastened on the bottom portion in a suitable manner as by tongues 53.. In this way, the end Walls are strengthened by the extensions 52 which constitute metallic struts resisting compression. It will be noted that these `fasteners are longer than the fasteners 29 in the form illustrated i'n Figs. 1 and 2, and thus may further strengthen and stiifen the end flaps and ltherebyv the ent-ire facey of the Wrapper.
In the form illustrated in Figs. 5 and 6, the end portions 25b and 261 of the side flaps are formed With inwardly inclined walls 60 over which the end portion 31b of the .metallic fasteners are bent, thus resisting an in- Ward pull upon theflaps as well as an outward pull. The lfasteners 29b 'are also formed with projections 61 which may be turned over to strengthen the corners.
In the form illustrated in Figs. 7 and 8,
lthe side flaps 13 and 14 are each formed with a plurality of notches 19c and 20. These notches are preferably not quite so deep as the notches used in constructions illustrated in Figs. 1 to 4f. In other respects the construction is similar to these figures.
In Figs.'9 and 10, a modified construction is illustrated which is adapted for use in connection with a Wrapper or box of a stiffer material lsuch as corrugated board, getc. The flaps 13d and 14d when folded over into closed position abut each other 'and are formed with end projections 25d and 26d which respectively abut the end projections 27d and 28d of the opposed flap. 'I'he fasteners 29d are formed with the end projections 31d which may be bent over the projections 25d; 27 d, etc., and also With a side projection or tongue which may be turned over the meeting edges of the abutting projecting Aportions.. In this Way, the aps are securely held in position.
From the various forms of my invention above described, itwill be seen that I have provided a mailing wrapper in which the side aps are interlocked with each other and also with the end Haps by the same fasteners to securely hold the wrapper when it is fastened for shipment. f Although the wrapper is thus securely held, it is still readily fastened and unfastened, the fastening pieces in some cases not only holding the flaps but also strengthening and bracing the wrapper itself.
Having thus described my invention, I claim- 1. A wrapper having a body portion, end iiaps,'and meeting side flaps extending over the end flaps, said side flaps being formed with registering projections and' fasteners attached to the end flaps adapted to engage theprojections to hold the side flaps rmly to the end flaps. Y.
2. A wrapper having end'and side walls, end flaps and side flaps extending from the respective walls, said side flaps being formed with registering projections, and fasteners attached to the end fia-ps adapted to engage the projections to hold the side flaps firmly to the end flaps.
