Application March as, 1936, Serial No. 10,471

'iClaims. ('01. 229-45) of are located at points quite remote from the place of manufacture, and consequently it is necessary to ship the merchandise to them in large quantities. l Il'his is naturally attended with appreciable cost and employment of unproductive labor, all going-to the over-head expense that must be borne by the retailer or distributor, and ultimately by the consumer.

A further disadvantage attending the above condition is that the cartons aremanufactured and shipped in the identicalform in which used,

i. e., the cartons are. actually shipped in precisely the form or shape for use, or in other words they are in the shape of maximum capacity and due to the shipment of this unnecessary bulk freight rates or express charges, are in large part wholly unnecessary and this again only adds to the cost to be borne by the retailer and ultimately by the consumer. A further disadvantage is that large space is required for storing any appreciable supply of the cartons ready for use by the average distributor. To overcome these disadvantages the present invention has for its purpose to provide a paper carton which is collapsible to the end that large numbers thereof may be packed at the place of manufacture and so shipped to the retailer who may then use the same only as required thus necessity for maintaining space required for storage purposes.

The invention is shown by way of illustration in the accompanying drawing wherein:

Figure 1 is an elevational view showing the carton parts disassembled, and with the container portion collapsed.

Figure 2 a longitudinal sectional view thereof.

Figure 3 an elevational view showing the carton in set-up position ready for filling.

Figure 4 an enlarged and central sectional view of the carton in set-up position.

Figure 5 an elevational view showing the carton with a modified form'of inspection aperture, and;

Figure 6 a similar view showing a further modified arrangement of inspection aperture.

Referring to the construction in further detail and wherein like reference characters designate corresponding parts in the different figures, the carton consists ofa body or container portion 1 avoiding needless expense and the constructed preferably of paperand of a size which, when set up, will hold the usual measureof carton in standard sizes. Said body'portion is adapted to be collapsed after the manner indicated in Figures 1 and 2, wherein it is folded upon 5 itself along the two medial lines 8- as shown, and in this condition the same are adapted to be packed at the point of manufacture and shipped 7 to places of use.

The container'portion or body I is constructed 10 preferably after-the manner of a truncated cone, and at its base or larger end, is sealed by a single and impervious closure 9 hollow'like or conical in shape and having an appreciable marginal portion l0 seduredto the inner peripheral surface II by suitable adhesive as indicated in Figure 4. The conical closure portion 9 is also folded upon itself along medial lines l2, as in Figure 1, and it will be noted that the folded or double edged portions of the body 'I' and closure part9 lie in substantially the same plane as clearly shown in Figure 2.

r The open or smaller end I3 of the body 1 is provided with a removable cap 14, constructed preferably of the same material as carton body I, and has a flange I 5 that fits snugly about the side of the container end l3. Said cap or closure is preferably, provided with a re-enforcing disc member ll suitably secured to its inner surface} though of sufliciently less diameter-toprovide an annular groove or channel way that receives the marginal edge of the wall portion It as shown. With this arrangement it will be-evident that a tight and effective seal is maintained between the removable capand the carton.

The .closed and larger end of the carton is also provided with a re-enforcing element in the nature of an apertured disc I! that fits tightly within the open base portion as in Figure 4, and has its peripheral edge lying in intimate contact with the carton wall 1 substantially along the circumferential line of union between the flange portion Ill and said wall. It will be understoodthat the reenforcing disc I! is adapted to be placed in position when the carton is shaped into its open or cylindrical form preparatory to filling."

The invention further contemplates a means for inspecting the approximate contents therein and to this end the body I has a plurality of apertures l8 arranged in staggered relation so as to provide a sulwtantially continuous opening, or in lieu of several apertures l8 a single slot. l9 may be provided, or a series of diagonally disposed slots 20 may be formed as shown in Figure 6. In this latter instance the upper edge of a lower slot is in horizontal alinement with the lower edge of 55 the next slot above thus presenting a continuous opening, and a strip of transparent material 2|, e. g. cellophane or the like overlies the inner surface of the carton covering said slots as shown.

It will be understood the invention as herein disclosed is not limited to the details of construction shown and described since these may be varied widely without departing from the spirit of the invention as defined by the claims.

What is claimed as new is:

1. A carton of the character described comprising a two sided and cylindrical collapsible body portion, an impervious foldable and hollow shaped bottom piece secured thereto around its peripheral edge, and a removable closure member, substantially as set forth.

2. A carton of the character described comprising a cylindrical and collapsible body portion, an impervious foldable and hollow shaped bottom piece secured theretoaround its peripheral edge, and a removable closure member, substantially as set forth. I

3. A carton of the character described comprising a cylindrical and collapsible body portion, an

impervious conical and foldable bottom piece'secured thereto, and a removable closure member, substantially as set forth.

4. A carton of the character described comprising a collapsible body portion of truncated conical form open at its smaller end, an impervious conical and foldable piece secured to and closing the larger end thereto, and a removable closure member for the open end, substantially as set forth.

5. A carton of the character described comprising a cylindrical body portion foldable medially upon itself into a substantially flat piece, an impervious conical and foldable piece secured to and closing one end of said body portion, and a removable closure member for the open end, substantially as set forth.

6. A carton of the character described comprising a cylindrical body portion foldable medially upon itself into a substantially flat' piece, a conical and foldable piece secured to and closing one end of said body portion, and a re-enforcing disk fitting within. the body portion at the closed end when the carton is distended, substantially as set forth.

7. A carton of the character described comprising a collapsible body portion of truncated conical design, a foldable and hollow shaped clo sure piece secured to the larger end thereof around its peripheral edge, a. removable closure cap for the smaller end, and a removable disk for the larger end, said cap and disk adapted to reinforce and hold the carton in distended or open position, substantially as set forth.
