' Application filed February 2, 191.8. Serial No. 215,057.

To all whom t may concern:

` Be it known that I, WILLIAM G. MENNEN, al citizen of the United States, and a resident of Newark, in the'county of Essex and State of New Jersey, have invented new and useful Improvements in Cartons, of which the following is-a specification.

The invention relates to cartons, and more especially to cartons of elongated form, such as are used as retail packages for talcum powder. These cartons as now commonly constructed comprise inner and outer shells, the inner shell having a sifter top and the outer shell being closed at the bottom. The inner shell is longer than the outer shell, and over the projecting end of the inner shell is placed a slip cover. These three parts are supplied separately by the boxmaker to the powder manufacturer, and the latter has to assemble them, and, in certain instances, to apply a finishing sheet or a label or both. In `filling the old-style pack age the inner shell is inverted and filled by hand. The outer shell is then inverted and slipped over the inner shell, which latter has been coated with adhesive to make the shells stick together. The contents are now inclosed upon all sides. The cover is next slipped over the projecting upper portion of the inner shell, and finally a` finishing sheet is pasted around the outer shell and the sides of the cover, thus holding the cover in place. If the finishing sheet does not constitute the label, a separate label is also applied. In some cases the outer shell and cover are finished by the boxmaker and the powder manufacturer secures the cover by Y pasting a small label or a seal over the joint.

Such boxes are disadvantageous as compared with my improved construction, in that the packer is obliged to handle the separated elements of the box, that the single shell, which receives the powder in thefirst instance, is non-rigid and liable to distortion, and that the packaging cannot well be effected by means of machinery.

` My improved box also comprises inner and outer shells and a slip cover, but all of these may bev and preferably are assembled by the box-maker. who may also put on the label sheet, or other means for securing the cover, so that the box may be practically completed before it reaches the powder manufacturer. In any event the shells are telescoped and united to form a stijf body before'the filling is effected. In one end of `this bodyis a cardboard disk having a filllng opening, and after the contents have been introduced through such disk, the opening 1s covered by a cardboard closure disk which is cemented in the end over the brace. In the herein preferred embodiment of the invention the outer shell extends slightly below the inner shell at the bottom, and the frame or apertured disk is inserted by the box-maker inside the lower end of the outer shell and against the end of the inner shell, where it is advantageously held by folding over the lower edge of the label sheet, which is made long for the purpose, and pasting it against the bottom of the frame. This frame or filling opening disk performs the important function of bracing the end of the box prior to and duringthe filling operation, and aifords a surface against which to paste or glue the closure disk. The box bodies before the application of the closure disk are substantially rigid, both because they are double-walled, and because of the brace, and their character makes possible mechanical filling. Thus, the boxes may be placed upside down upon a conveyer and carried beneath a spout, after which, either by hand or by machine, adhesive may be applied and the bottom closure disk pressed into place.

In the accompanying drawings illustrating the invention:

Figure l is an inverted perspective view of the box without the bottom closure disk and with a portion of the label sheet torn away to show the parts beneath;

Fig. 2 is a perspective view of the bottom closure disk;

Fig. 3 is an enlarged fragmentary longitudinal section showing the disk in place;

Fig. 4 is a vertical section through the completed and closed box, right side up; and

Fig. 5 is an enlarged fragmentary longitudinal section showing the relation of the inner and outer shells and the label sheet at the bottom of the box before the insertion of the frame.

In Fig. et the closure disk is shown as if loose and small for its recess in the bottom of the box, in order that the representation of the interposed portion of the label sheet may not be obscured; but it will be understood that as a matter of fact when the package is completed the disk is glued dat against 'the frame and preferably fills the recess snugly.

The inner and outer shells 2 and 3 may be substantially oblong in cross-section, as shown, or of other form, and are formed to it snugly one into the other. The inner shell is preferably formed with a top wall l0,

having a sifter 11, and is longer than the outer shell, so as to extend beyond the upper end of the latter, in order to receive the slip cover 4, as in prior practice. The outer shell element, however, instead oi' being formed with a closed lower end, -is preferably open at both ends, being in edectja short length of cardboard tubing.

A combined label and finishing sheet 5 is shown covering the sides oi both the outer shell and the cover, at the junction of which the sheet may `be perforated or provided with a cutting line 12. Fig. 5 illustrates the fact that the lower end of the outer shell projects slightly beyond the lower end of the inner shell, and that the label sheet in turn extends beyond both. At this stage in the production ofthe box the cardboard disk or brace 6, in which is cut a large filling opening 9, is introduced into the lower end oi the outer shell and against the stop aiforded by the edge of the inner shell, lthe disk being exteriorly shaped and sized to fit the interior of the outer shell. The free portion 7 of the label sheet is now turned in and pasted down upon the disk, as shown in Fig. 1. rlhis holds the disk in place and secures a neat linish for the lower end of the box.

The box body, as shown in Fig. 1, is now ready Jfor the powder manufacturer, who receives with the bodies a supply of the -bottom closure disks 8 illustrated in Fig. 2. The box is inverted for filling, represented in Fig. 1, and the `material is introduced through the large opening 9 in the disk 6. After the box has been lilled, adhesive is spread upon the bottom surface of' the filling opening 6 and the lap 7 of the label sheet, or alternatively upon the inner side of the closure disk 8, and the latter is pushed into its permanent position, seen in Figs. 3 and 4. The closure disks may consist of single pieces 13, wholly inclosed in the bottom of the box, but preferably these disks are made of two thicknesses or lifts, the outer or lower lift 14 being slightly larger than the inner, so as to coact with the lower edge of the shell 2 for the purpose of making a more leak-proof joint. The closure disk may also be made of a single piece of pressed board, either with 01 without the extension edge.

The user cuts the label or other sealing means at the junction 12, in the ordinary manner, and removes the cover 4, thereby exposing the upper sifter end oit the inner shell.

What I claim as new is:

1. In a carton of the kind described, the

combination of inner and outer cardboard shellstelescoped and united, the inner shell projecting substantially above the outer shell and having a sifter top, a slip cover for the projecting sifter top end of the inner shell, a cardboard disk having a Vfilling opening inserted into the open lower Yend of the outer shell Aagainst the edge of the inner shell, and a bottom closure disk.

2. In a carton of the kind "described, the combination 'of inner and outer Icardboard shells :telescoped and united, ithe :inner shell than the `thickness of said 1lling-.opening 85 disk and a `closure disk formed :to be inserted in and to fit the 4bottom recess thus afforded.

3. A carton .of the kind described, come prising inner `and outer cardboard shells telescoped and united, ,the inner shell projecting above the outer shell at the top, a slip cover on the top `projecting portion of the inner shell, and a. bracing 'bottom portion containing a filling `opening combined with a closure :disk `which is permanently secured beneath said bottom portion `when Y the carton has been filled.

Li. A carton of the kind described, comprising inner and outer cardboard shells telescoped and united, the inner shell vprojecting substantially above :the outer shell at lthe top and the outer shell extending slightly below the inner shell at the bottom,

a slip cover on the top yprojecting portion of the inner shell, a bracing vbottom .portion containing a filling vopening at the rlower end of the inner shell and above the lower end of the outer shell, and a bottom closure disk formed to enter 'the-open lower `end eine the outer shell and having an extension edge to coact with the lower edge of the outer shell.

5. A carton of the kind described, comprising a body formed of inner and outer cardboard shells telescoped and united with the inner shell projecting above the `outer shell, a slip cover for said ytop projecting portion, one end of the body being closed by a permanentfend wall, a diskinthe other end or' the body containing a filling opening, and a closure disk which is'cemented over aid lling opening disk when the box is illed.
