.4 Claims. 1

This invention relates to devices for urging individual articles arranged in stacked relation within a package or wrapper toward a remote opening in the package so that the articles may be conveniently reached and removed from the package through the opening.

It is an object of the invention to provide a device of the class described particularly adapted for insertion into a conventional cigarette packet.

Another object of the invention is to provide in an expansible feeder for insertion within a cigarette packet, a novel telescopic spring for actuating the feeder.

Another object of the invention is to provide a feeder of extremely thin construction which will not crowd the contents of the sealed packet into which it is inserted.

Another object of the invention is to provide a feeder of extremely thin construction which may be recovered for repeated use.

Another object of the invention is to provide a feeder, for insertion into a sealed packet, which embodies a novel expansive member which when compressed becomes no thicker in bulk than any one of its expansive arms.

A further object of the invention is to provide a feeder which may be inserted into a sealed cigarette packet through a very small entrance opening pierced through a wall of the packet.

Another object of the invention is to provide a feeder of extremely thin construction embodying a novel means of latching the device in compressed position to reduce its bulk and so facilitate handling as well as to provide protection for its expansible member.

Still another object of the invention is to provide an expansible feeder which may be inserted into a cigarette packet locked in compressed position and which, after insertion thereof, may be unlocked by a simple motion imparted thereto.

The invention possesses other objects and fea, tures of advantage, some of which, together with the foregoing, will be specifically brought out in the detailed description of the invention hereunto annexed. It is to be understood that the Figure 3 is a perspective view, similar to Figure 2, illustrating how the feeder is inserted into the cigarette packet.

Figure 4 is a side elevational view of a cigarette packet showing the feeder of my invention 'in position therein. A portion of the view is broken away and other portions are shown in vertical section so as to more clearly disclose the internal construction.

Figure 5 is a perspective view of the feeder shown in its expanded condition.

Figure 6 is a perspective view of the feeder as seen from the back and shows the position of the latch when the feeder is latched in compressed position. It also shows the position of the novel leaf spring when so compressed.

Referring to the drawing, Sheet 2:

Figure '7 is a side elevation View, similar to Figure 4, and shows a modified latch hook formed from one of the spring arms.

Figure 8 is a perspective view of the feeder in its expanded position and shows the modified latch hook as a part of one of the spring arms.

Figure 9 is a side elevation view, similar to Figure 7, and shows the novel latch, as in Figures 4, 5, and 6, when using a modified type of expansible member.

Figure 10 is a perspective view of the feeding device in its expanded position, and shows the position of the component parts of the latch device and the modified type of expansible memher.

invention is not to be limited to the specific I p In detail, my invention, which is best shown ,in Figure 5, comprises a backing plate 6 of sheet metal having at its upper end a tab 1 bent at right angles to the plate and provided along its purved edge with serrations 8. ,A pair of parallel tongues 9 are cut from the backing plate adjapent the lower rounded end thereof and are clinched over the end bar H of a leaf spring so as to slidably secure one end of the latter to the backing plate thus permitting slight longitudinal, movement of the leaf spring with respect .to the backing plate. The leaf spring is formed, preferably, from a single piece of sheet metal having spring characteristics, such as Phosphor bronze, and is provided with four parallel, longitudinally extending slits which divide the spring into a plurality of integrally connected arms I2, l3, and I4. These arms are flexed beyond their elastic limit so that they assume a normal set expanded position as shown in Figure 5.

I A pusher plate It, which has a rounded lower end complemental to that of the backing plate 6, is secured, intermediate its ends, to the outermost end of the arm l4 by the rivet or spot weld I5. Prior to being put in use, the feeder is compressed, as shown in Figure 1, so that the backing plate 6 and the pusher plate I6 are brought into close proximity with the leaf spring compressed therebetween and a latch is provided for releasably holding them in this position comprising a tongue integrally formed from the pusher plate intermediate its ends and bent outwardly from, and upwardly in parallel relation to, the pusher plate to form a tongue I8 which is adapted to pass through an aperture i9, provided in and intermediate the ends of the backing plate, and to hook over the upper edge 2| of the aperture. Since the pusher plate is secured to the leaf spring, and, since the leaf spring when compressed assumes, substantially, the form of a rigid intermediate plate slidably secured to the backing plate, a slight relative longitudinal movement between the backing and pusher plates permits the tongue l8 to be engaged or released from the backing plate.

A .modified form of the tongue I8 is shown in Figures. '7' and 8' where a tongue :1 is provided from-an extended end portion of the spring arm l'4 bent outwardly from and upwardly in parallel relation to the pusher plate, said tongue I! being adapted to passv through the aperture i9 and to hook over the upper edge 2! of the aperture.

A, modified form of the expansible member is shown in Figures 9 and 10 comprising an obelisk spiral spring 24 and attached by welding to the pusher plate at points25v and to the backing plate at points 26.. The flexibility of, the spiral spring permits slight longitudinal movement between the backing and pusher plates so that the tongue l8 may be engaged, with or released from the upper edge 2! of the aperture l9 of the backing plate 6.

The ordinary smoker, in opening a packet 22 of cigarettes, will usually tear away the wrapper in. one corner of .the packet, as shown. in Figure 2, so as to provide a dispensing opening through which the cigarettes 23 maybe removed as required. While the packet is nearly full, the cigarettes may be easily and quickly removed, but at the same time it is possible for the cigarettes to fall loosely from the packet into. the pocket or to clutter the handbag with attending mutilation. Moreover, as the contents of the packet are removed, it :becomes increasingly vdiflicult to reach and remove the cigarettes since the latter are situated remote from the dispensing opening. There is yet another undesirable feature, since the partially emptied packet will collapse in the users pocket causing him bothersome fumbling to reopen the dispensing opening when he desires a cigarette and possibly causing breakage of the latter in the attempt. to remove it from the packet.

The feeder of my invention obviates these disadvantages. After tearing away one corner of the packet to provide the dispensing opening, as shown in Figure 2, the user grips the collapsed feeder shown in Figure 1 and proceeds, with the serrated edge of the tab 7. to cut a slit through the wrapper in the top of the package at the opposite end thereof from the dispensing opening. The feeder, with the rounded ends of the backing and pusher plates 6 and i6 foremost, is then inserted into the packet as far as it will go. Thispositions the collapsed feeder inside of the packet between the inner side of the-wrapper and the stack of cigarettes as may be seen by reference to Figure 4. When the feeder has been fully inserted into the packet, the exposed tab 1, Figures 4, '7, and 9 is grasped and drawn sufliciently upwardly to release the latch tongue I8 from the backing plate whereupon the collapsed leaf spring will be released and will forcibly urge the pusher plate 16 against the side of the stack: The tab 1? is then pushed in flush with the top. of the packet. It: will :be readily seen, in Figures 4, '7, and 9 that as uccessive cigarettes are removed from the packet through the dispensing opening the expanding leaf spring will force the remainder of the stack toward the opening. Thus the cigarettes are maintained within easy reach of the users fingers. It will also be seen that the presence of the feeder within the packet prevents collapse of the latter when carried in the pocket and prevents the attendant crushing and breaking of the cigarettes. After thelast cigarette, has been removed from the packet, the latter is torn open so as to recover the. feeder and the latter is collapsed and latched ready for insertion into another packet.

While I have shown a feeder particularly adapted to the more common type. of cigarette packet, it will be evident that the design may be varied to suit. different packet constructions without departing, from the spirit of the. invention. It will also be evident that a wide variety of suitable materials may be employed in the construction of the feeder and that ordinary spring wire may be substituted for the sheet material shown without losing any of the advantages ofthe invention.
