In Ge July 15, 1937 I 1 Claim. (c1; 229-23) Round boxes have beenknown for a long time. They are supplied by the manufacturing industries gummed or pressed complete. On account of the manufacturing costs and shipping ex- 5 pensesbeing considerably elevated, these beauti-. ful boxes were not so successful as the straight edge folding boxes.

Experiments of various kinds have been made to manufacture collapsible round boxes, which failed however, as the mounting of the boxes required too much work and involved greater consumption of materials, and for many other difllculties.

. It is known to make a collapsible roller-like 15 cardboard box, in which the openings of the closed cardboard roller areclosed with cap-like covers.

It is also known to make a non-gummed cardboard box in such a manner that by the aid of die moulds the individual parts are lined with in thin paper and thereby kept together.

The two mentioned, boxes are of a somewhat similar type, but as regards the principles and 35 stitching and without the use-,of machines, tools,

etc. I

Fig. 1 shows the bottom of the box formed by the two disks I and 2. The dotted line 3 represents the outside gumming line.,

"Fig. 2 shows the cross-section of the bottom and in which way the two disks are pasted; In particular here the-ungummed rim and the slotlike groove become visible. 45 Fig. 3 shows the rim of the bottom part of the box. The flaps I and I which are bent rectangulai'ly inwardly at the score lines 6 in setting the box together. The flaps only serve for decorative purposes. The closing of the rim consists of slot If and the flap 8.

Fig. 4' shows the lid 'of the boxwhich only distinguishes itself-from Fig. 1 by a somewhat \larger diameter. Y I V Fig. 5 shows the rim of the'lid which only distinguishes itself from Fig. 3 by an extended length according to Fig. 4.

Fig. '6 shows the set up bottom part of the box. Fig.7showsthesetupupperpartofthcb0t.

such a way that the rims are lying unglued on the rims.

In order to describe the invention more clearly, reference is made to the annexed drawing showing a box of 'circular shape with loose cover ass in Figs. 6 and '7, in which v No. i is a plate forming the base part, to which 5 a smaller plate 2 is gummed, stitched or attached in'any other way in such a manner that the gummed surface, or fastening line begins at or on line 3 (Figs. 1 and 2) in inward direction. Thereby, a free, slot-like grooved rim 2-3. is 1 formed which is designed to receive the teeth of the belt. The exact length of the belt part is determined by the circumference of plate 2. The lengthwise sides of the belt (Fig. 1i) of the base part are provided with round teeth 4, 5 which serve, partly for jointing the double bottom, partly for stiffening and decorative purposes (as visible, see Fig. 6). The score lines 6, H enable the teeth to be folded over easily and precisely.

The parts of the top (Figs. 4'and 5) are distinguished from those of the bottom part only in two-respects: 'the belt of the upper part and therefore also plate 9must be of longer or larger form as they will later have to fit over the. belt of the bottom part. The belt of the top part is I provided with teeth only on one side, Fig. 5.

when mounting the box, the teeth of the belt are bent rectangularly in inward direction and set into the groove of the corresponding plates of the upper or lower part, respectively. When closdesign. Figs. 6. and 7 showthe round folding box mounted complete in opened condition.

By giving the double plates diflerent forms it is possible to produce a great variety of box shapes. r

The invention cannot only be used in connectionwith thick paper and cardboard, but is also suitable formetallic and modern raw materials.

Having nowv described my invention I declare that I claim as new:

A round foldingbox consisting of bottom, cover, and two flattened out rims which, when required, can be set up by the user to form a two-part box without glue or other additional means thus characterized that the bottom and cover consist of two cardboard disks which are glued together in top of each other ina certaindepth forming a slot-like groove which rectangularly bent rimflaps are inserted and, in closing the rims, connect the bottom and the cover respectively firmly with HANS PABB'I.
