  • Supporting means 12 includes a single cardboard core section 14 which frictionally engages the internal bore 16 of roll 10, Then ends 18 and 20 of core section 14 are substantially coterminous with the ends 22 and 24 of roll 10.
  • Supporting means 12 also includes trunnion means 26 and 28 positioned, respectively, within core section ends 18 and 20. As will be apparent from FIG. 1, the total axial length of supporting means 12, comprising core section 14 and trunnion means 26 and 28, is greater than the axial length of roll 10.
  • Trunnion means 26 comprises an annular outer core section-engaging portion 30, and annular inner dispenserengaging portion 32, which portions are joined within bore 16 inwardly from coterminous ends 18 and 22 of core section 14 and roll 10, respectively, by an annular web 34.

  • An appropriate dispenser for rotatably supporting roll 10 includes channel-shaped guide element 46 within which dispenser-engaging portion 32 of trunnion means 26 is received, and channel-shaped guide element 48 within which dispenser-engaging portion 40 of trunnion means 28 is received.
  • Guide element 46 includes a lower inwardly sloping camming surface 50 which, incident to the gravitational force acting downwardly on roll 10 and supporting means 12, urges the roll and supporting means axially leftwardly as seen in FIG. 1, by cammingly engaging portion 32 of trunnion means 26,
  • left end 24 of roll 10 will be urged against the innermost edges 52 of guide element 48.
  • the frictional engagement of roll with edges 52 acts as a rotational brake on the roll to minimize inadvertent or intentional spinning thereof, and thus reduces wasting of the tissue comprising roll 10.
  • Guide element 48 includes a cutout 54 which is axially aligned with core section 14 and outer portion 38 of trunnion means 28. Below cutout 54, the channel depth of guide element 48 is increased forming a recess 55 in the lower portion thereof. As shown in FIG. 1, recess 55 is axially aligned with inner portion 40 of trunnion means 28; the substantially horizontal lower edge 56 of guide element 48 defining the lower extent of recess 55 and serving as a trunnion means-engaging element for rotatably supporting roll 10 in the dispenser.
  • supporting means 12 Upon exhaustion of the toilet tissue comprising roll 10 from about core section 14, supporting means 12 will be urged to the left by the aforementioned camming action of surface 50 against portion 32, whereupon lower edge 56 of guide element 48 will be received within recess 44, and left end of core section 14 and outer portion 38 of trunnion means 28 will be received within cutout 54, as shown in FIG. 2. Due to the leftward axial movement of supporting means 12, inner portion 32 of trunnion means 26 will become disengaged from lower surface 50 of guide element 46 and the right end of the supporting means will fall out of the dispenser, as shown by the arrow in FIG. 2.
  • trunnion means 26 disengages from and falls out of the dispenser
  • trunnion means 28 will be disengaged from guide element 48 and supporting means 12 will fall downwardly out of the dispenser. It will be seen from this description that due to the disparity between the axial lengths of roll 10 and supporting means 12, the supporting means is adapted to fall out of a dispenser automatically after the toilet tissue comprising roll 10 has been exhausted from thereabout.
  • Two rolls 10 of the embodiment of the invention shown in FIG. 1 are shown in FIG. 4 stacked in end-toend relationship to thereby facilitate the packaging and storage thereof.
  • End-to-end stacking of the rolls is made possible by the nestable relationship of trunnion means 26 and 28.
  • the inside diameter of inner portion is greater than the outside diameter of inner portion 32. Therefore, portion 32 of trunnion means 26 of a supporting means 12 within a first roll 10 may be nestably received by portion 40 of trunnion means 28 of the supporting means 12 within a second roll. This nestable relationship between portions 32 and 40 of adjacent rolls 10 permits the rolls to be stacked in end-to-end relationship.
  • FIG. 5 shows a second embodiment of the invention comprising a roll of toilet tissue 10 and an internal supporting means 58 positioned within the roll.
  • Supporting means 58 includes two core sections 60 and 62. The adjacent ends of sections 60 and 62 abut one another within bore 16 of roll 10 at juncture 63.

  • core section 62 and trunnion means 28 positioned therein are permitted to move axially leftwardly in a dispenser similar to that shown in FIG. 1, permitting core sections 60 and 62 to separate at juncture 63. Thereafter, the core sections individually fall downwardly out of the dispenser as shown by the phantom lines and arrows in FIG. 5.
  • the inner layer of tissue roll 10 may be secured to core section 62 by an adhesive, such as glue strips 64 and 66.
  • an adhesive such as glue strips 64 and 66.
  • supporting means 58 although embodying a plurality of axially aligned and abutting core sections, overcomes the disadvantages of the prior art devices, such as the core section embodiments disclosed in Perrin Patent 3,214,014, by including means which cause at least one of the core sections to move axially outwardly upon exhaustion of the tissue from thereabout, thus ensuring that the abutting core sections will be separated effectively within the dispenser.
  • FIG. 6 A third embodiment of the invention is shown in FIG. 6 which in many respects is similar to the previously described embodiments. However, this embodiment includes a supporting means 68 comprising core sections 70 and 72 having their respective adjacent ends 71 and 73 axially spaced apart within bore 16. In all other respects, the embodiment of FIG. 6 is identical to the embodiment of FIG. 5.

Closed ends 75 and 77 engage inner portions 40 and 32, respectively, of the trunnion means 28 and 26, to thus provide means for rotatably supporting roll 10 in the dispenser.
  • FIG. 7 A fourth embodiment of the invention is shown in FIG. 7 comprising tissue roll 10 which is wound about a supporting means 80 of a greater axial length than the surrounding roll.
  • Supporting means 80 comprises two axially aligned core sections 82 and 84. Adjacent ends 83 and 85 of sections 82 and 84, respectively, are axially spaced apart within bore 16 of roll 10. Ends 86 and 88 of sections 82 and 84, respectively, which are nearest the ends of roll 10, project axially outwardly therefrom so that the outer portions of the core sections will rotatably support roll 10 in an appropriate dispenser.
  • the dispenser may include two vertically slotted members 90 and 92 which receive the outer portions of core sections 82 and 84, respectively, for rotatably supporting roll 10 in the dispenser, similarly to the manner in which the tissue roll of the embodiment shown in FIG. 6 is held in an appropriate dispenser. After the tissue has been exhausted from about core sections 82 and 84, the sections merely fall downwardly out of the dispenser.
  • FIG. 8 A fifth embodiment of the invention is shown in FIG. 8, comprising a tissue roll 10 having a supporting means 94 positioned therein.
  • the manner in which adjacent rolls 10 of this embodiment may be stacked in end-to-end relationship is illustrated in FIG, 8.
  • Supporting means 94 includes core sections 70 and 72 which are identical to the core sections employed in the embodiment of FIG. 6. The adjacent edges 71 and 73 of the core sections are axially spaced apart within bore 16 so that after the tissue has been substantially exhausted from about the core sections, supporting means 94 will collapse and fall downwardly out of an appropriate dispenser.
  • Trunnion means 96 comprises an annular internal core section-engaging portion 100 and an annular external dispenser-engaging portion 102. External portion 102 is of a lesser diameter than internal portion 100 and is integrally afiixed thereto by an annular collar 104 positioned within bore 16 inwardly from the coterminous ends of core section 70 and roll 10.
  • T runnion means 98 comprises a hollow annular internal core section-engaging portion 106 and a hollow annular external dispenser-engaging portion 108; external portion 108 being integrally affixed to internal portion 106 adjacent the coterminous ends of core section 72 and roll 10.
  • the inside diameters of hollow portions 106 and 108 of trunnion means 98 are greater than the outside diameter of external portion 102 of trunnion means 96. Due to the disparity between the diameters of portion 102, and portions 106 and 108, portion 102 of the supporting means 94 within a first roll may be nestably received by portions 106 and 108 of the supporting means within a second roll and the rolls thereby stacked in end-to-end relationship.
  • Roll 10 of the embodiment of FIG. 8 may be held in a dispenser which is similar to that shown in FIG. 6, such dispenser having two vertically slotted supports with closed lower ends for engaging external portions 102 and 108 of the trunnion means 96 and 98, respectively.
  • FIGS. 1, 5, 6, 7 and 8 each encompass a roll of toilet tissue having positioned therein a supporting means for providing the roll with internal support while it is held in a dispenser, which supporting means is of a greater axial length than the surrounding roll. More significantly, as has been described in connection with each of the foregoing embodiments, due to the disparity between the axial lengths of the roll and the internal supporting means therefor, the supporting means is adapted to fall out of an appropriate dispenser automatically upon exhaustion of the toilet tissue from thereabout.
  • Trunnion means 110 is generally similar to the trunnion means 26 and 28 employed in the embodiments of FIGS. 1, and 6, comprising an annular outer core section-engaging portion 112, an annular inner dispenser-engaging portion 114 and an annular web 116 which joins portions 112 and 114 within bore 16 inwardly from the coterminous ends of core section 70 and roll 10.
