csnnnoaan BOX AND cnnron Application filed November 21, 1928, Serial No.

This invention relates to improvements in cardboard boxes and cartons and method of and means for manufacturing the same, and refers more particularly to that class of decorative containers which are used for packing and vending dried fruit, confectionery and the like. I

lIhe materials which are used consist of strips of cardboard having lugs along one edge thereof, such strips being used to form the sides of the box or lid, discs of cardboard which in conjunction with the lugs form the floor or the lid, small adhesive strips of paper or the like which unite the ends of the side strips, and in a modification of the device, other sheets of adhesive paper of varying size and shape which are applied to the floor and lid of the carton to join these portions together. For convenience of description the last mentioned adhesive sheets are hereinafter referred to as the adhesive labels.

In addition to the foregoing materials I use a binding sheet which consists of strong but thin material such as silk, cloth or tissue pa er, but preferably material commercially own as cellophane which is very thin and transparent, and in some cases an ananular disc or ring-like formation of cardboard is also used.

The elements required for manufacturing the box or carton consist of a moulding frame preferably made of sheet metal having an inturned flange along its lower edge, and a press block, the former being accommodated in a suitable recess in a bench or frame and the latter being supported on a plunger or a Vertically moving frame of any conven-- 320,829, and in Australia September 21, 1928.

moulding element and the block will correspondingly conform to such shape.

For the better elucidation of my invention I will now describe the same by aid of'the accompanying illustrative drawing wherein:

Figs. 1 to 8 inclusive illustrate the materials from which the box is made. to 12 inclusive indicate the operative elements used in the manufacture, and Figs. 13 to 18 inclusive illustrate the principal steps in the operation of manufacture.

In the drawing Fig. l is an elevation of a serrated strip for the walls of a cylindrical or oval shaped box and having lugs thereon to form a part of the lid or floor.

Fig. :2 is an elevation of a strip of material suitable for forming the walls of a hexagonal box, and is typical of the wall required for boxes of varying shapes.

Fig. 3 is a small binding strip of adhesive material..

Figs. 4 and 5 illustrate plan views of the strips in Figs. 1 and 2 having their lugs inturned and their ends joined with adhesive for a cylindrical or hexagonal box.-

Fig. 6 is an internal disc of cardboard, for a cylindrical box or lid.

Fig. 7 is a sheet of binding material on to a convenient shape.

Fig. 8 is a disc or plate of cardboard for a hexagonal box or lid.

Fig. 12 is a plan of the moulding element for a hexagonal box or lid.

Fig. 13 illustrates a strip of cardboard as in Fig. 1 mounted upon the block, and a disc Figs. 9,

of cardboard and binder resting on the top of Fig. 15 illustrates the tucking in of the overhanging edge or skirt of the binder.

Fig. 16 illustrates the completion of the operation, the structure having been removed from the mould and an additional disc of cardboard having been forced inside of the box or lid and resting upon the turn over or outer edge of the binder.

Fig. 17 is an enlargement of portion of ig. 18 is an enlargement of portion of Fig. 16.

In each of the illustrations similar letters of reference are used to denote similar or corresponding parts wherever they occur.

In the drawing a is the strip of cardboard for forming the wall of the box or lid, such strip having a serrated edge forming lugs a. This wall strip is rolled or bent to confirm to the shape of the intended box or carton as in Figs. 4 and 5, the ends having been brought'into contact and secured by the adhesive strip. 1) shown in Fig. 3 which may be of any convenient size or shape.

In manufacturing the box or carton or its lid, the wall strip is placed on the body of' the vertical plunger block a which may either be operated by hand or may be provided with a spindle or shank d mounted in guides e as in Figs. 9 and 10, and fitted with any me chanical device for imparting an elevating or depressing motion thereto.

An air space 0' and a vent is provided to avoid suction when the block is withdrawn.

The moulding element is preferably made of sheet metal and consists of walls I of cylindrical or other shape and a flange f, there being an open space in the bottom of the moulding element as indicated in Figs. 11 and 12.

This moulding element may be used manually, but is preferably supported in a frame 9 which rests upon a bench h the moulding element being in true vertical alignment with the block 0 its internal walls being standardized to correspond with the diameter or width of the external wall of the intended structure.

The adaptation of the strip to the block for the purpose indicated is shown in Fig. 13 wherein the binding material j of Fig. 7 is laid across the top of the moulding element,

iindl a disc such as is shown in Figs. 6 or 8 is The next step in manufacture consists in causing the block 0 to descend into the mould carrying the wall with it. This action also presses the cardboard disc is into the mould which simultaneously drags the binder with it so that the binder is accommodated between the inner wall of the moulding element and the outside of the wall of the box as in Fig. 14:, the edges of the binder being caused to assume the position indicated in Fig 14. The mould may now be removed from its frame and the binder is tucked into i the mould preferably by hand as indicated in Fig. 15 so that it lies against the inside wall of the box or lid, its extreme edges resting on the floor. k

When the tucking operation has been com pleted an additional disc similar to the disc is, but indicated in Figs. 16 and 18 as k, is forced into the box or lid, and during its passage to the bottom thereof it further smoothes the intucked binder as well as the portion thereof which rests along the disc is, the disc being substantially similar in size to the diameter of the inner wall of the box or lid so that when forced to the bottom it presses circumferentially and evenl against the inner bottom edge of the wall t us holding the binder'in position by frictional gri From theforegoing specification it will e seen that the box or lid which has thus been binder, the intermediate wall and lower disc in, whilst the interior of the box or lid is covered with the continuation or skirt of the im wardly turned binder which is held by the second disc 70, the inturned extreme edges of the binder being thus fastened. Both the box and its lid are formed substantially in the manner and by the means and with the materials herein described, and an important feature of my invention lies in the fact that with the exception of the binding strip which joins the abutting ends of the wall, no paste, glue or other adhesive material is required in the manufacture.

In a modified form of my device an annular disc or a disc with a central opening may be used instead of the discs k and k for the lid of the box so that if transparent binding material such as cellophane is used on the outside the goods contained in the box will be readily visible through the transparent covering.

Having now particularly described and as certained the nature of my said invention, and in What manner the same is to be performed, I declare that what I claim is:

1. An improved cardboard box or carton comprising an external binder of thin flexible material, a disc in the central area of the binder, a side wall formed of a strip of material having its ends joined together and having inturned lugs along its lower edge, said lugs being-located above said disc, said binder extending outside the wall and disc and inturned within said wall, and a second disc within the box and resting on the inturned portion of said binder.

2. A box body or lid comprising an unattached assembly of an end, a false end, a continuous side wall, and a wrap sheet of thin flexible material, the side walls being notched along one edge to form lugs, the In 5 being inbent and resting upon said end, t e wrap sheet covering said end and extending up around the side wall and infolded thereover and extending downwardly then horizontally over said tabs and the false end restin on the wrap infold and covering the infol ed bottom portion'.,

3. A box body or lid comprising a side wall, and an end wall, a wrap sheet of thin flexible material extending under said end wall and embracing said side wall, said wrap sheet being infolded and downfolded within the side of said side wall, an end disc fitting within the body, the infolded skirt portion of the wrap sheet extending down within the box and tucked in under said end disc to hold said sheet to said body without an adhesive.

4. A box body comprising a side wall having inturned lugs, an end and a wrap sheet of thin flexible material extending under said end and embracing said wall said wrap sheet being infolded and then folded over the inner side of said wall and above said lugs, a false end within the body portionv and pressed down upon the inwardly extending portion of said flexible material.

5. A container comprising an annular side wall having an inwardly projecting portion at an end, a disc lying adjacent said portion, a wrapping of flexible sheet material covering said side wall and disc and tucked within the other end of said side wall and a second disc inserted within said side wall and firmly holding said tucked-in wrapping against said side wall and under said second disc.

6. A container comprising-an annular side wall, a wrapping of flexible thin sheet material across the endof the container and covering the-outer surface of said side wall and tucked within the other endof said side wall, and an inserted member firmly holding said tucked-in wrapping against said side wall.

In testimony whereof I aflix my signature.

MILNE GIBSON.
