TOILET PAPER ROLL CORE Filed Feb. 16, 1952 IN V EN TOR. L4 WHZNJF A. HEINLE' BY '42 M W ATIK ted States Patent I Of TOILET PAPER ROLL CORE Lawrence A. Heinle, San Mateo, Calif. Application February 16, 1952, Serial No. 271,938

1 Claim. (Cl. 242-552) This invention relates to cores for rolls of material more particularly to the tubular paper cores for rolls of toilet paper.

An object of this invention is to provide a core of skeleton form for rolls of sheet material such as toilet paper.

Another object of this invention is to reduce the quantity of material in a paper roll core.

Another object of this invention is to provide a core for a roll of toilet paper which permits access therethrough to a mounting or supporting device for the roll.

And another object of this invention is to provide a readily disintegrating core for a roll of toilet paper thereby aiding in the disposal thereof.

Still another object is to provide such a core which is restricted from axial movement on its spindle.

Other objects and advantages of this invention relating to the arrangement, operation and function of the related elements of the structure, to various details of construction, to combinations of parts and to economies of manufacture, will be apparent to those skilled in the art upon consideration of the following description and appended claim, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Referring to the drawings:

Fig. 1 is a perspective view of a core for a roll of paper embodying features of the invention herein;

Fig. 2 is a vertical section through a roll of toilet paper incorporating a core or spool of the invention herein and including a mounting device element therefor;

Fig. 3 is a side elevation of a core, parts being broken away to disclose a form of mounting device therefor; and

Fig. 4 is a perspective view showing a modified form of a core embodying the invention herein.

Numerous forms and types of devices are employed for mounting rolls of paper, particularly toilet paper and most types of these brackets embody spindles which, many in turn, incorporate mechanisms requiring manual manipulations to allow removal of the paper core after the supply of paper has been exhausted therefrom.

There is herein shown a mounting spindle 10, having a roll of toilet paper 12 thereon, the device illustrated embodying clutch mechanism for engaging the interior of the core 14 of the paper roll. A suitable bracket (not shown) is used to mount the spindle at any convenient location.

The invention herein embodies a novel construction for the core 14. A preferred form for the core comprises a paper tube of predetermined length extending between its termini 16, 18. The length thereof normally come sponds to the width of paper wound thereon so that the circumferential outer face or wall 20 of the core 14 is encased by the wraps of the paper thereon.

The wall 20 of the core 14 is provided with a pair of Patented June 2,1959


elongated openings 22 therethrough, preferably diametrically opposed. These openings 22 are of substantial area and have. their termini adjacent the termini 16, 18, of the tube.

When the paper has been exhausted from the roll 12, the core 14 remains on the spindle 10. The spindle may then be manually engaged through the openings 22 to slide the spindle from the core or any mechanism 26 embodied in the spindle may be manually operated. Means are thus provided to aid in the removal of empty cores 14 from mounting spindles. Radial access to the core in terior is provided through the wall 20 by the elongated apertures 22.

Such a mechanism embodied in the spindle 10 may be located in a plurality of axially extending slots 11 (see Figs. 2 and 3) transverse of which may be mounted axle pins 25 for pivotally mounting holding elements 26 limited in their radially outward movement by abutments 13 at the opposite ends of each slot 11 from that of the pivots 25. These abutments 13 may cooperate with shoulders 27 on the pivoted holding elements 26 which elements 26 are preferably normally urged radially outwardly so that their shoulders 27 rest against the abutments 13 by resilient means such as the springs 29. Thus, the toilet roll core 14 may he slid over the spindle 10 by pressing inwardly the holding element 26 so its outer end will clear the inside diameter of the spindle, and then when the roll core is in place on the spindle, the two holding elements 26 along one side of the spindle snap into the slot 22 to engage the opposite end edges 24 thereof to restrict axial movement of the roll core 14 with respect to the spindle 10. When the paper 12 is completely used, compression of a holding element 26 at one end of the spindle 10 through the slot 22 enables the core 14 to he slid off an end of the spindle.

Extending between the termini 24 of the openings 22 and the termini 16, 18 of the core 14, are score lines 28. When the empty cores are removed from their spindles, these score lines 28 aid in crushing the skeleton core for disposal. Also, if the core is deposited in a toilet, as is a frequent occurrence in public toilets particularly, the score lines 28 aid in a rapid disintegration of the core in the water of the toilet, thereby preventing clogging and permitting flushing away of the core without damage to the toilet installation.

The openings through the core wall may be of various dimensions and to accommodate some types of mounts, the core wall 20 is provided with openings 30 extending inwardly from the core termini 16, 18, to their respective termini 32. The notch or cut away portions 30 may be longitudinally and radially aligned or disposed in pairs angularly offset as illustrated in Fig. 4.

The openings through the core wall in any instance of arrangement, are preferably of a size to permit easy finger entrance therethrough.

It is to be understood that the above detailed description of the present invention is intended to disclose an embodiment thereof to those skilled in the art, but that the invention is not to be construed as limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of being practiced and carried out in various ways without departing from the spirit of the invention. The language used in the specification relating to the operation and function of the elements of the invention is employed for purposes of description and not of limitation, and it is not intended to limit the scope of the following claim beyond the requirements of the prior art.

assenm What is claimed and desired to secure by United States Letters Patent:

In combination with a cylindrical core-mounting spindle having diametrically opposed, axially extending slots therein, holding elements pivot-ally mounted in said slots for swinging movement from positions within said slots to positions in which they protrude from said slots, at

of said pair disposed adjacent opposite end walls of the slots for restricting relative axial motion between said spindle and said core, the slots in said core being of such width and length as to permit the free passage of an operators fingers therethough to release said holding elements.
