Claims. (Cl. 229-19) This invention pertains to cartons or containers formed by folding from blanks or sheets of fiber-board or other material and, more particularly, to a carton peculiarly adapted to hold 5 and retain, for shipment, display and handling, various articles such as soap, bottles and the like which need substantial protection against breakage and disfigurement during transportation and other handling.

One of the primary objects of the invention, therefore, is to provide a carton of such construction that the articles it may contain will be secure therein against damage through rough or careless handling.

Another of the primary objects is to provide a carton so constructed and arranged that it will employ a minimum amount of material with a minimum amount of waste and a minimum of labor in its manufacture, and one which may be shipped in unfolded or knocked-down condition to be folded or set-up at its destination or point of use, the construction also being such that the unfolded or knocked-down cartons will occupy a minimum amount of shipping space for a given quantity of cartons.

Still another important object is to provide a carton construction of such character that the part thereof actually utilized to receive and to hold the particular commodity packaged therein may be made from a single blank or sheet of fiber-board or other suitable material, an enclosing tube or cover, if desired or utilized, being composed from another single blank or sheet of the same or some other material. In this connection it should be understood that the part of the carton which is to carry the commodity, as distinguished from the covering tube or jacket, may be utilized alone' as a carton or container and without any cover or jacket or with a mere wrapping of cellophane or the like.

A further object is to provide a novel carton constructed from a single sheet or blank of fiberboard or other material and in which the sides and ends are re-enforced and, in efiect, padded by formation in box-like section to absorb shocks and blows which might otherwise injure the carton contents. In this connection it is to be noted that the preferred construction is such that the carton when folded into its proper form from the blank, is self-sustaining and self-contained so that it is not dependent upon auxiliary means to hold its various sections in proper shape and relation to one another. I

And, among other objects, is provision of a carton in the form of a tray or similar receptacle particularly'suitable for the reception and retention for display and other purposes of bars or cakes of soap, the provision of a carton having an article receiving well into which commodities such as cakes or bars of soap whether wrapped or not, may be flitted snugly and frictionally held therein, and the provision of a neat, compact and easily handled carton.

Many other objects as well as the uses and numerous advantages of the invention should be apparent and understood after reading the following description and claims and after viewing the drawings in which:

Fig. 1 is a perspective view of a preferred form of the invention showing the tray or body part of the carton partially withdrawn from the enclosing tube or jacket part.

Fig. 2 is a perspective view of an end portion of tray or body part with some of the sections folded into formed position and other sections in open or unfolded position but ready to be'folded.

Fig. 3 is another perspective view of the end portion shown in Fig. 2 but with the end wall folded into shape except for a broken part the better illustrating the construction and folding sequence. a

Fig. 4 is a section through an end wall taken along the section line IV-IV of Fig. 1.

Fig. 5 is a developed view of the carton tray or body part or, in other words, a plan view of a sheet or blank as cut and scored ready to be folded into shape, and

Fig. 6 is a small scale view in plan of the blan or sheet from which the tube or jacket part of the carton is to be formed and showing the score lines along which folding is to occur.

Referring first to Figs. 1 and 6 it will be noted that the tube or jacket part generally designated A may be formed from a single blank cut in the shape shown in Fig. 6. Dotted lines 1, 8, 9 and I1 indicate score lines or lines along which the folding is to occur and segregate the blank into bottom and top wall sections, i2 and I3, respectively, side wall sections l4 and I5, and a sealing flap i6 upon which glue or other adhesive may be placed for securing the same to the inside face of the side wall section l5. As the blank is illustrated with its outside surface toward the observer, the folding will carry the folded sections away from the observer. The tube or jacket is made in such dimensions as snubly to receive the tray part with a sliding fit therein and may extend for the full length of the tray or terminate beyond or short of the ends thereof as desired. The jacket or tube cover may be shipped in blank form for folding at the place of use or it may be pre-folded at the place of manufacture and then folded down flat at'diagonally opposite corners'and shipped in that condition.

The tray or body part generally designated B in Fig. 1, is formed by folding from a blank such as that illustrated in Fig. The blank comprises a bottom wall section l1, 2. top wall section l8, side wall sections l9 and 2|, and a side wall sealing flap 22 upon one face of which an adhesive may be applied for securing the flap to the inside face or surface of side wall section 2|. The sections and flap mentioned are segregated by score or folding lines 23, 24, 25 and are inktended to be folded away from the observer (viewing Fig. 5) into shape.

The bottom, top and side wall sections are generally rectangular in shape and the ends of each are provided with integral portions to be utilized in constructing the end walls and in securing the ends in closed position. As previously indicated the carton isprcvided with box=section side and end walls for protection of the contents and to this end each longitudinal end of the bottom wall section I! has a projecting portion generally designated 21 adapted to form the end walls and is divided by score lines 28, 29, 3| and 32 into segments or parts 33, 34, 35 and 36 the purpose and use of which will later appear, and, along the score line 23, has pre-formed slits 31 which receive fastening tabs as will also appear herein= after. Segments or parts 34, 35 and ,36 are slightly reduced in their lengths at each end tc provide clearance from adjacent parts as will be understood as the description unfolds.

The top wali section |8 has a projecting end wall cover flap or portion 38 at each end segregated irom the body ofthe top section by a score line 39 and each portion 38 carries a pair of tabs 40 segregated by score lines 4| and adapted to be tucked. or inserted through the slits 31 when the blank has'been folded. Extending for a substantial distance along the longitudinal center line or axis of symmetry of the top section and of a slight width is a pre=formed slot 42 which at each of its opposite ends is flared or widened outinto triangular shape as shown at 43 with the bases of the triangles parallel to the score lines 39. The sides of the triangle lie along lines substantially bisecting the adjacent corners of the top section, in the embodiment shown, and slits 44 extend from the slots 43 outwardly along said bisecting lines for a substantial distance. The slots 42, 43 and the slits 44 together with longitudinal score lines 45 and transverse score lines 46, define segments or parts 41 and 48, the former of which, in turn, are divided by score lines 49 to provide parts 5|. ihe functions and purposes of these parts will appear later. Each side wall section, l9 and 2|,

has a tab flap 52 at each end segregated from itsbe preferable to .execute the first folding along score lines 23, 24, 25 and 26 to form a tube, the adhesive on flap 22 securing this flap and side wall 2| together. Thereafter it is relatively immaterial whether the box-section end walls or the box-section side walls next be formed. If the end walls be chosen, the segments, or parts pletes each end except for the flap segments 48 which may be bent down as illustrated in Figs. 2 and i.

The box-section side walls are formed from the segments or parts 41 and 5| of the top wall l8, these segments being folded in the same direction along score lines 45 and 49 to the positions shown in Fig. 2. It will be observed that the car- -ton thus constructed provides a well in the top of the tray part into which articles such as cakes of soap may be disposed fordisplay or other purposes, the slight tendency of the box-section side walls and of the flap segments 48 to return to their original positions with respect to the top, serving to an extent to exert sufficient frictional efiect upon the articles contained in the well as to secure the articles relatively firmly therein. Of course, the dimensions of the carton will be so chosen as to provide a snug or other proper fit for the articles to be received therein.

The carton is not only strong and secure and able to protect its contents but is attractive in appearance and simple to construct as well as economical and relatively inexpensive. It will be observed that the segments 54 and 55 included between score lines 25-45 and 39-46, respectively, provide marginal framing about the well in the top section which lends attractiveness as well as utility to the construction. The widths of segments 55, preferably are the same as the widths of segments 34 and 36 while the widths of segments 33 and 35 are equal and adapted to bring segment 34 snugly beneath and into supporting contact with the bottom faces'of segments 55. Likewise segments 5| and 54 are substantially equal, preferably, with one another in width so that segments 41 will stand perpendicular to the bottom wall I! and parallel tn the segments I9 and 2|.

While I have illustrated and described a preferred embodiment of the invention, it will be appreciated and understood that variations and modifications may be made without departing from the spirit of the invention and the scope of the app-ended claims.
