which can be shipped in a package usable as a magazine, or a package in which the caps with tabs. is merely emptied into the magazine in much the same manner as with the tubes now used for caps without tabs. It is, however, preferable to use the package as a magazine both when caps with, and without, tabs are used.

This tube possesses the added advantage of permitting visibility of the caps in the tube whereby the operator of the capping machine can tell at a glance how the caps are feeding into the machine, and what quantity remain in the tube at a given instance.

This package for discoidal bottle caps com-' prises a tube 1 formed with a lengthwise slot 2 usually opening through at least one end thereof, the slot being of such width to slidably receive the tabs B, when caps with peripheral tabs are used, or through which the tabs B project, and the diameter of the tube being approximately the same as the discoidal body A of the caps, or of such diameter that the caps slidably feed therein, so that they will readily slide into the tube, and the tabs slide in the slot, at the factory where the caps are manufactured, and will also readily feed out of the tube, when the tube is mounted as a magazine in a bottle capping machine, or when emptied in the magazine of a capping machine.

Usually, the slot extends through both ends of the tube, and when the caps are placed therein, the ends of the tube'are sealed in any suitable manner. Preferably, the lower end of the tube, or package, is sealed by the strip 23 secured over the ends of the tube. The opposite end may also be sealed in like manner, but is preferably sealed by crimping, or rolling, inwardly the end of the tube, as at l. These seals are effective to avoid confusion as to which end of the tube should be inserted in the magazine holder of the capping machine. It will be understood that the caps usually bear printing on one side thereof and accordingly, the package, or tube, must be so placed in the magazine holder of the machine that the caps. are applied to the bottles with the printed side up.

Preferably, the slot is formed by splitting the tube from end to end, expanding the tube, or letting it expand by its own resiliency, thereby separating the edges at opposite sides of the split sufficiently to form the slot 2, and in order that the interior of-the expanded tube may substantially conform as to size and shape to the periphery of the discoidal body of the caps. In this instance, the tube is initially formed of slightly less diameter than that of the caps and expanded, or allowed to expand after being split, to substantially the diameter of the discoidal'caps in order that the caps may be readily fed thereinto, and also feed out of the same. The sealing means holds the split tube from undue expansion, and retains the caps in the tube during handling of the same.

As seen in Figure 3, the slitting, or slotting, may terminate short of the outer, or upper, end of the tube, or the and remote from the strip closure, as at 5. In this instance, the tube is initially formed with the proper diameter to receive the caps, and a strip is cut out of one side of the tube to form the slot 2. In view of the fact that the slot 2 terminates short of the upper end of the tube, that end of the tube is more rigid, and the tube is more easily handled and filled. The end of the tube is sealed preferably by crimping, or turning in,

in the same manner as when the slot extends the entire length of the tube, the lower end of the tube being sealed with the strip 3.

B designates the magazine holder of a capping machine and into which one end of the tube constituting the package is inserted. These holders are provided with angular shoulders 1 against which the ends of the tube, when used as a magazine, squarely abut although, it is not necessary that they actually abut against the shoulder-1, they should be square therewith in order to insure a proper feeding of the cap out of the magazine tube. If the end of the magazine tube is ragged, or uneven, the operator is quite likely to insert the tube too far, or because of the ragged edge, a portion thereof is liable to bend inwardly, either condition resulting in obstructing the feeding of the caps from the tube. The sealing strip 3 can be readily removed without mutilating the magazine tube, and the liability of mislocating the tube in the magazine holder, is eliminated.

In order to also insure the proper location of the package when used as a magazine tube in the magazine holder 6 of a capping machine, stop means, self contained with the tube, are provided for coacting with the upper edge of the mega-- zine holder 6, which stop means normally is part of the tube, or continuous therewith, and is foldable outwardly into a position whereby it serves as a stop by engaging the upper edge of the holder 6.

As here shown, this stop means consists of diametrically opposite tabs 8 struck from the body of the tube i, and normally lying flush with the body of the tube l and being foldable into angular position, as shown in Figure 2, where they act as stops by engaging the upper edge of the magazine holder 6. These tabs are so located relatively to the end of the tube as to coast with the magazine holder Gwhen the lower end of the tube engages the shoulder l, or slightly before the lower end of the tube reaches the shoulder I.

In operation, the dairyman removes the tube from the carton in which it is shipped, tears oil the sealing strip 3 and pulls out the tabs 8 and inserts the end of the tube, which is provided with the sealing strip, into the magazine holder 6, the stops 8 limiting the movement therein and preventing the tube from being inserted too far into the holder 6 to such a depth that the lower end thereof will pass beyond the shoulder i and be contracted into such a small circle as to grip the disk and prevent the feeding thereof, or in case of a slotted tube, to such an extent as to cause the sides of the slot to grip the caps. Owing to the fact that the upper end of the tube is crimped, or rolled, the dairymen can not inadvertently get the tube in upside down. Owing to the rolled margin 4, at the outer end of the tube l, the dairymen can readily see the disks with the printed sides up. Also, owing to the slot 2, during the feeding, the disks are always visible, and it is readily apparent to the operator whether or not the disks are feeding properly.

This package for caps of the type having radial tabs is particularly advantageous in that the caps may be packed therein as economically as discoidal caps without tabs can be packed in tubes, and also the tubes with the caps with the tabs packed therein can be used as a magazine in the capping machine, thus making caps with tabs which project beyond the peripheral edge as economical in manufacture, packing and applying to the bottle, as the conventional discoidal cap without tabs extending beyond their peripheral edges.

What I claim is: a 1
