PACKAGE 0F SENSITIZED MATERIAL.

Application med March 15,192.3. Serial No. 625,241.

sensitized material and more particularly to a roll of material, at least a part of which is sensitized, the outermost convolution of which is secured by an adhesive sticker sheet to the next inner convolution. 1

" It is common to 4place such sticker sheets in a position entirely covering the extreme end of the` band. In heavy rolls, as` of paper for a Commercial copying camera, these sticker sheets are made of fairly strong material and it is not always an easy matter to tear them and start the unrolling`of the band. The objects of this in vention are toirnprove the method of securing the freeend f such a band, to permit` the use of a stick r of fairly strong material, and to provide a strong manipulating tab by which such a sticker may be readily torn. These and other objects are attained by' the structure hereinafter described,`and illustrated in the accompanying drawing in which:

' Fig. 1 is a perspective view of a package secured by my improved means;

"Fig.. 2 is a section of 'such' a roll showingvthei startingof the opening action;

Fig. 3 is a, plan of the end of the band before being folded; y

Fig. 4 is a similarv view showing the folded arrangement; p

Fig. 5 is an elevation of a package With a modified arrangement;

Fig. 6 is a plan of the end of a band folded as shown in Fig. 5. J

The form of package which I have chosen to illustrate my invention comprises a long band ofmaterial 1,'at least a p-art of which is sensitized, Wound into a roll and carried on end hubs 2 which engage the innermost convolution '3 frictionallyi and which are secured to.end nanges 4t with reinforced roiinded edges 5. the details of the spool or coil as such are not claimed, they lneed not be further described. i

This invention relates" to a package Aof- In my preferred form the end of the band 1s cut symmetrically to form edges 6 at an angle toy the side edges 7 and meeting at a point 0. These are then bent back on thelines 0B, so that the edges 6 meet and `abut on the mid-line o f the band. The

bent over flaps lie on the underside of the band and are firmly held in position qby the band when rolled, thourh .they may be adhesively secured if desirv There is thus formed a tapered end portion 9 which is strengthened and'reinforced throughout its length by the iaps 8. 'The angle originally made by the edges determines the angle of Vthe line 0B .when the edges 6 are ben-t to longitudinal osition, and AI have found the proportions s iown'to be satisfactory ferably shouldv not be as long as a complete convolution of the band, but it should be long enough to provide a longtaper permit? ting the ready placing of a sticker sheet y10 transversely thereof. The sticker sheet will be placed far enough from tip 0 to leave a' tab 11 which may be easily grasped and which is strong enough so that when -,pulled it will readily disrupt' the sheet 10, even though the latter 1s made of fairly strong materlal. The sticker. sheet is referably made of paper coated on its un ersurface vvithan adhesive b Whichy its central ortlon 1s secured to t e tapered end 9 an its ends 16 are securedto the next inner convolution of Vband 1. shows the sheet 10 partially disrupted, one end portion 16 being shown as 'in contact. With the neXt convolution, while the tab 11 is carrying with it the central' Fig.

portion of the sticker sheet. As is Shown, the reinforced tabis thicker and stronger than. sheet 10. f

A modified form of'reinforced end is illustrated in Figs. 5 and.6. The band 1 has at its end symmetricaly inclined edges 12 which are arranged at the angle of the desired final taper, and the extreme tip 13 is bent straight backen the line 14, transverse of the band. It is bent under the band and may be adhesively secured if desired.,y This tapered portion of the band as used is blunt ended and only'the extreme end p ortion is reinforced" by the bent over portion I '15. This reinforcement, however, extends far enough back to form a tab of suiiicient The tapered portion pref' by Letters Patent is:

length for manipulation and the sticker sheet l0 will be applied at such a position as too-verlap the turned back portion 15.

It) is to be undersood that the above described forms areto be considered as exam: ples of my invention, and I' contemplate as Within thejsco'pe thereof all such modifications and equivalents as fall 'Within the terms of the appended claims.

Having thus described my invention, what I claim as neu7 and'desire lto .secure l. A package of sensitized material coinprising a` rolled band', the outer end portion of which is tapered, all of said tav,

pered portion being reinforced by a double thickness formed by folding the material back on itself, and a sticker sheet lying across said tapered portion, theends of 'the Vsticker sheet being secured tothe next inner convolution of the band and constituting the sole sealing means for the package, the extreme end of the tapered portion extending beyond the sticker .sheet and constituting a. manipulating tab.

2. A package of sensitized material comprisinga rolled band, the outer end ortion of which is symmetrically tapered-and reinforced, the reinforcements comprising` corner portions` folded back until their edges meet in the mid-line of the band, and

a# sticker sheet. lying across said tapered EDWARD P. FLYNN.
