6 Claims.

This invention relates to paper or cardboard containers.

Inexpensive paper containers of the tubular type are now extensively used as packages for merchandise, such as cosmetics, etc. It is an object of this invention to improve the construction and appearance of this type of container and to facilitate its manufacture, the improvements being particularly useful in a container of the dispensing type.

In most of the tubular paper containers now in use, the bottom disc is attached to the tubular body portion by a paper facing strip which. is adhesively secured to the edge portion of the disc and to the outer surface of the tubular body. I have provided a paper container in which a bottom cardboard disc is attached to the tubular body portion by a seamless metallic' clamping ring, this being made possible in a container of the inexpensive type because of the way in which the ring is made and applied to the container.

I have also provided an inexpensive paper container of the dispensing type by adding to the usual tubular container a few additional parts which are so made and applied as to convert the container into the dispensing type without materially increasing the cost of manufacture.

The features which give the container its dispensing characteristics may advantageously be combined in the same container with the feature of clamping the bottom disc inplace by a seamless metal ring because the sheet-metal that is left over when the clamping ring is formed may be utilized as a rotatable shutter for closing the 3 dispensing opening in the top disc of the container. This makes the combined use of these features quite feasible without taking the container out of the inexpensive class.

One form of container embodying the invention is illustrated in the accompanying drawings in which:

Figure 1 is a vertical section of the complete container;

Figure 2 is a horizontal section taken on the line 2--2 of Figure 1;

Figures 3, 4 and 5 are vertical sections illustrating the different steps involved in making the outer tubular member of the body;

Figure 11 is a vertical section showing how the bottom disc is applied to the body; and

Figure 12 is an enlarged vertical section showing the final step in clamping the bottom disc in place.

Referring first to Figure 1, the container comprises a tubular member or outer ring 1 made of paper or cardboard, provided at its upper edge with an inturned bead 2 and at its lower edge with an outwardly curved flange 3. Within the outer ring 1, there is an inner cardboard ring 4 between the upper edge of which and the head 2 are held three elements. The uppermost of these elements is a metallic disc 5 having a perforation 6. This constitutes the above mentioned rotatable shutter. The lowermost element is a cardboard disc 7 having a perforation 8. Between the metal disc 5 and the cardboard disc 7, there is a thin sheet of material 9, such as paper. The metal disc 5 is mounted loosely enough to permit it to rotate in its own plane when turned by hand, but there is enough friction to prevent it from turning of its own accord. The disc 5 is preferably provided with a pair of struck-up portions 10 projecting upwardly from the top surface of the disc to facilitate rotation of the disc by the fingers. (See also Fig. 2). In one position of the metal disc 5, its perforation 6 registers with the perforation 8 in the cardboard disc 7. This permits dispensing of the contents 11 of the container through the perforations 8 and 6 when the sheet material 9 is broken at this point. The contents of the container may be powder or any other material which it is desirable to package in a container of this type. In ordinary usage, rotation of the metal disc 5 to a position where its perforation 6 does not overlie any portion of the perforation 8 is probabl;-,- suflicient to effectively close the container, but the sheet 9 is provided as an additional precaution to more effectively seal the perforation 8 and mo prevent leakage of the powder during the time the container is subjected'to severe handling before it reaches the customer. Moreover, the use of the sheet or membrane 9 eliminates the necessity of using any special care when assembling the perforated discs 5 and 7 to see that the metal disc 5 is in the proper position to close the perforation 8 of the-disc '7, because even if the perforation 8 is not closed by the disc 5 it is neverno theless sealedby the membrane 9 until the membrane is broken.

The container is closed at its bottom by a cardboard disc 12 which is clamped against the flange The inturned bead 2 is then formed at its upper a bottom disc 12 to the container.

edge, as'lshownin Fig. 4, in.the customary way by spinning the ring against suitably shaped .dies. The ring 1a is then spun against another set of suitably shaped dies to form the outwardly curved flange 3 at its lower edge as shown in Figure 5. The metal clamping ring for attaching the bottom disc 12- to the outer ring 1 is stamped from a piece of thin sheet metal which is first formed to give it the shape of a shallow cup-like disc having'a web portion 17 and a vertical peripheral flange 18 as shown in Figs. 6 and 7. From the center of this cup-like member is stamped a disc represented by the-dotted line 19 in Figure 6. This leaves the metal ring shown in Fig. 9, having the vertical peripheral flange 18 and a short horizontal flange 20. The disc 19 which is removed to form the clamping ring is utilized for the metal sh'utter 5. In order to place it in condition to serve this purpose, it is only necessary to provide itwith the perforation 6 and the struck-up portions'lO as shown in Fig. 8.

The operations necessary to produce the remaining parts of the container require no special description. These parts comprise the sheet of paper or the like 9, the perforated cardboard disc '7 the inner ring 4, and the bottom disc 12.

Figure 10 shows in position for assembling, the outer ring 1, the metal shutter 5, the sheet of paper or the like 9, the perforated cardboard disc 7 and the inner cardboard ring 4. The shutter 5, thepaper sheet 9 and the disc 7 are moved into the ring 1 until they abut against the bead 2. The inner ring 4 is then forced into the outer ring 1 to hold these parts in place as shown in Figure 1. It is customary to fill the container through its open bottom before the bottom discis applied. For this purpose, the container, assembled to the extent already described, is turned upside down as shown in Figure 11. After it has received the contents 11, the bottom disc 12 and the metal ring 13 are applied. In Figure 11, these two memb rs are shown in position ready for application the container. The bottom disc 12 is caused to abut against the outturned flange 13 on the outer ring 1, and then the ring 13 is caused to-telescope over the edge of the disc 12 and the flange 13. The peripheral flange 1 8 of the ring is then bent inwardly and downwardly and clamped against the flange 3 of the outer ring 1 This firmly attaches the Here. it should be noted that the inner diameter of the peripheral flange 18 on the metal ring is substantially the same as the diameter of the bottom disc 12 and the outer diameter of the outturned flange 3. The diameter of the metal shutter 5 is substantially equal to or slightly less than the inner diameter of the outer ring 1. When the disc 19 as shown in Fig. 12.

is stamped from the cup-shaped member shown in Figures 6 and 'Z to produce the metal clamping ring and the metal shutter, both the ring and the shutter are of the proper size without removal of any more material so that the horizontal flange 20 on the metal ring extends the proper distance over the peripheral edge of the bottom disc 12 and so that the shutter properly fits within the outer ring 1 and rotatively abuts against the intumed bead 2.

The outturned flange 3 on the outer ring 1 and the peripheral edge of the bottom disc 12 project radially a shortdistance beyond the cover. These portions of the container are given a neat and attractive appearance by the metal clampingring which likewise projects radially beyond the cover and constitutes a convenient place to grasp the body of the container while the cover is being withdrawn.

It should be noted that the shutter is rotatably held in place without the necessity of using a central pivot of any kind. Because of the way in which I rotatably position the metal shutter and because of the fact that this metal shutter is conveniently provided at the time the metal clamping ring is made, I am enabled to add to an inexpensive dispensing container a metallic rotatable shutter without materially increasing the cost of the container. Likewise, I am enabled to clamp the bottom cardboard disc of an inexpensive container in place by a seamless metallic ring without materially increasing the cost because of the way in which the ring is formed and applied. This is particularly true in a container of the dispensing type because a metal shutter can be conveniently provided at the same time as the clamping ring hereinbefore described. The metal clamping ring not only has structural ad-v vantages over the facing strip heretofore used m for adhesively attaching the bottom disc to the tubular body, but it can be more readily and quickly applied and it also materially improves the appearance of the container.

I claim:

1. A paper container comprising a tubular body portion, a bottom disc, an annular seamless sheetmetal clamping ring by which the bottom disc is attached to the body portion, an intumed bead at the upper edge of said tubular body portion, and a sheet-metal disc within the body portion and abutting against said bead, said sheet-metal disc being a part removed from the same sheet of metal from which said clamping ring was formed and being of the same size as the opening in the clamping ring.

2. A paper container comprising a tubular body portion having an inturned. bead at its upper edge, a bottom disc, ring and a sheet-metal disc both of which constitute stampings from the same sheet of metal, said clamping ring being applied to the bottom edge of an annular sheet-metal clamping metal, said metal disc beingthe same size as the opening left by its removal from the metal sheet, the clamping ring being applied to the bottom edge of the bodyportion and to the bottom disc to clamp the latter to the body portion, and said sheet-metal disc unaltered as to size being positioned within the body portion against said inturned head.

4. A paper container comprising a tubular body portion having an outwardly turned flange at its lower edge, a bottom disc whose upper surface abuts against and radially overlaps the lower face of said flange, and a seamless metal ring bent around said flangeand the edge portion of the disc and serving to clamp the upper surface of the disc to therlower face of said flange and thereby secure the disc to said tubular body portion.

5. A paper container comprising a card board tubular body portion having its lower edge flared outwardly to form a flange, a bottom card board I substantially the same.
