PAGKAGE OF ABRASIVE STRIPS Filed July 19, 1958 Patented May 23, 1939 UNITED STATES PATENT OFFICE 2,159,634 PACKAGE F 'ABRASIVE s'rmrs Ralph T. Pitt, Quincy, Mass, assignor to Abrasive Products, Inc., Boston, Mass, a corporation of Massachusetts Application July 19, 1938, Serial No. 219,982

2 Claims. (Cl. 206-46) r This invention relates to a package of abrasive strips and more particularly strips useful for such purposes as manicuring or filing fingernails.

The package of the present invention is char- 510 be; kept intact until the supply of strips has been exhausted. Generally stated, the package comprises a stock of abrasive strips eachof diminishing width from one end to the other end thereof, an open frame encompassing the stack at its ,16 edges so that each strip is freely removable from the stackthrough the frame opening, and a band orring encompassing the frame transversely of the stackand slidable from the narrow-end portion tothe wide-end portion of the stack to engage and bridge the frame edges firmly and thereby to maintain the strips as a stack within the frame. When an abrasive strip is to be removed from the package, it is necessary only to slide the cross-band or ringto the narrow por- 25 tion ofthe stack, as this releases or loosens the frame from the edges of the strips and hence permits one or more strips to be freely withdrawn from the stack. Thereupon, the crossband or ring maybe slid back to the wide-end 30. portion of the stack to reengage the frame firmly against the strip edges andto hold the strips together as the desired package.

With the foregoing and other features and objects in view, the present invention will now 35 be described in further detail with particular reference to the accompanying drawing, wherein,

Figure 1 shows in perspective a band to constitute the open frame for the package hereof;

Figure 2 depicts the band after it has been 40 formed up into the frame or holder for the abrasive strips.

Figure 3 shows the frame as it is being filled up with strips in stacked relationship.

Figure 4 depicts the cross-band or ring for the 45 package hereof.

Figure 5 is a plan view of the package with the cross-band or ring at the narrow end portion thereof. Figure 6 is a similar view after the cross-band 50 has been moved to the wide-end portion of the package and is thus capable of maintaining the tstackof strips firmly in place. :Figure 7 is a section through the package on the line 1-1 of Figure 6 after a few strips have 55 been removed therefrom.

The band It) appearing in Figure 1 may consist of paperboard or paper of appropriate thickness and stiffness, namely, such as not to buckle at its edges when engaged firmly by the crossband or ring of the package hereof. A transverse ,5 slit l l maybe cut approximately midway into the band from its opposite longitudinal edges near each of its end edges. The end portions of the band may be interlocked so that the edges of the. slit or cut II at one end portion hooks or 10 engages over the intact band portion immediately in line with the slit at the other end portion. By providing a transverse crease or line of score I2 in the band substantially centrally of its end edges, interlocking of the end portions of the band develops the elongated open frame l3 shown in Figure 2. The internal girth of such frame I3 is preferably only slightly greater than the total edge length of theabrasive strip to be engaged thereby.

The abrasive strips to be packaged accordant with the present invention are each shaped to simulate the usual steel finger-nail file. Thus, as illustrated in Figure 3, each strip I4 is of progressively diminishing or tapering width from one end portion to the other, the wide-end portion l4a preferably being rounded at its edges and the narrow-end portion [4b also being shown rounded at its edges but, if desired, being pointed. In some instances, it may be desirable to create 30, in one of the side edges of the strip a curved or arcuate recess corresponding to the curved or arcuate recess usually occurring in one of the side edges of the usual steel manicuring file nearits wide-end portion. The strip ['4 may be cut from sandpaper, emery cloth, or other suitable abrasive sheet material either or both of whose faces carry bonded thereto abrasive grain of suitable size or fineness.

In forming the package hereof, the strips I4 40 are stacked one above the other in the frame 13 as it rests on a table or support until the frame is filled from its bottom to its top edge. The frame assumes substantially the configuration of the strips, which are of a stiffness to expand frame and to bridge the frame openings transversely and thereby prevent the abrasive strips from falling out of the frame openings. The band or ring l5 may be readily and economically made by adhesively securing the end portions l5a of a paper band into overlapping relationship. It is preferable that the paper of the band l5 be of somewhat less thickness and stiffness than that of the frame l3, for this means that such band may be made to encompass firmly the wide-end portion of the frame with little tendency to bend or distort the upper frame edges unduly even when, as shown in Figure 7, the strip supply or stack within the frame has been partially exhausted, or when the strip supply is largely or completely exhausted.

The band or ring i5 is assembled with the stacked frame by being first slipped over the narrow-end portion of the frame, as illustrated in Figure 5-, and then being pushed or slid to the wide-end portion of the frame until it engages such latter portion tightly, as shown in Figures 6 and 7, and can go no farther without being torn or ruptured. In suchv latter position, the ring 15- causes the frame l3 to engage frictionally or hugclosely the edges of the stacked strips and to keep the strips from falling out of the frame. When it is desired to remove an abrasive strip from the frame 13, the ring I5 is slid to the narrow-end portion of the frame, thereby releasing the frame wall from its tight or close frictional engagement of the strip edges and enabling a strip to be removed from the stack most readily in a direction away from the narrow-end portion of the package, that is, in the direction of the arrow appearing in Figure 5.

When one or more strips have thus been removed from the package, the ring I5 may be returned or slid back to its position indicated in Figures 6 and 7 and thus serve to maintain in the desired packaged or assembled condition the remaining strips of the stack.

The package hereof may, if desired, be wrapped in Cellophane, paper, or other suitable wrapping material for shipment and sale. Because of its compactness and integrity, it lends itself nicely to being carried in a pocket or pocketbook. It is to be understood that the package hereof is subject to change or modification while falling within the spirit or scope of the present invention, as defined by the appended claims. For instance, it is possible to form up the frame [3 from a paper or paperboard band whose end portions, rather than being interlocked as hereinb efore described, are adhesively or otherwise secured. Again, the band or ring structure I5 may be of seamless structure and be made of suitable flexible material other than paper, for instance, such flexible sheet or film material as Cellophane or its equivalent. The use of suitable paper as the material of construction for the frame l3 and the ring l5 has, however, been found to be economical and quite satisfactory in actual practice.

I claim:

1. A package of abrasive strips comprising a stack of such strips each of diminishing width from one end portion to the other end portion, an open frame encompassing said stack of strips at their edges, and a band encompassing the frame transversely of said stack and'slidable on said frame from its narrow-end portion to its wide-end portion, said band being engageable firmly with the wide-end frame portion to maintain the strips as a stack within said frame.

2. A package of abrasive strips comprising a stack of such strips each of diminishing width from one end portion to the other, a paper band encompassing said stack of strips at their edges,

each of said strips being freely removable from
