How to get from fig. 1 recognizes is the inner ring part 40 hollow and has an inner diameter that is larger than the outer diameter of the annular inner Part 32. The inequality of the diameters of parts 32 and 32 makes it possible to insert part 32 into a first role 10 by the part 40 in a second role, as will be explained in detail later. In order to adjacent rolls 10 can be stacked with the end on top of each other

A suitable roll holder for the rotatable mounting of the Roller 10 contains a profile-shaped guide element 46, into which the part engaging with the holder 32 of the pin 26 is received, as well as a profile-shaped guide element 48 in which the with the holder engaging part 40 of the pin 28 is received · The guide element 46 includes a downward sloping curl surface 50, which as a result of the on the roller 40 and the inner support 12 acting gravity Roll and the support in the axial direction according to fig. 1 can be held by the single grip of the rope 32 with the pin 26. As a result of the cam effect of the surface 50 against the part / 32, the left end 24 of the roller 10 is pressed against the inner edges 52 of the guide element 48.

The roll carrier falls out of the roll holder, as indicated by the arrow in FIG. After this If the pin 26 is detached from the holder and has fallen out of it, the pin 28 is also removed from the guide element 48 released and the roll carrier 12 falls down from the roll holder. One recognizes from this description, that due to the inequality between the axial lengths of roller 10 and roller carrier 12, the roller carrier can automatically fall out of the roller holder after the toilet paper sitting on the roll 10 is used up.

In Fig. 4 two rollers 10 of the embodiment of Fig. 1 are shown with the end stacked on top of each other, it can be seen that this significantly facilitates terpackaging and storage. Stacking the End-to-end rolling is made possible by the interlocking pins 26 and 28. As previously mentioned, the inner diameter of the inner part 40 is larger than the outer diameter of the inner part 32. As a result, the part 32 of the pin 26 of a roller carrier 12 in a first roller 10 in the part 40 of the pin 28 of the roller carrier 12 can be used in a second role. This interlocking of the parts 32 and 40 of adjacent rolls 10 enables the roll to be stacked end to end.

Fig. 5 shows a second embodiment of the invention with

~ "~ ORIGINAL

a toilet roll 10 and an inner roll support 58 disposed within the roll. Of the Roller carrier 58 consists of two core parts 60 and 62. The adjacent ends of parts 60 and 62 butt within the opening 16 of the roller 10 at the connection point 63 in front of each other.

In the outer ends of the core parts 60 and 62 pins 26 and 28, respectively, are inserted, which are identical to the pins, in the case of the roller carrier in the embodiment according to Pig. 1 apply.

After the toilet paper rom roll carrier 58 is consumed is, the core part 60 and the pin 28 in this core part may be similar axially to the left in the reel seat move as in FIG. 1, with core parts 60 and '62 separating at junction 63. Then fall the core parts individually down from the roll holder, as indicated by dashed lines in Fig. 5 and by the arrows is shown in FIG.

In order to prevent the roll carrier 58 from falling out automatically To facilitate a roll holder, the inner layer of the toilet paper roll 10 can be attached to the core part 60 with the help of a Adhesive, for example, be fixed by adhesive strips 64 and 66. By attaching the inner layer of the paper

- 14 109386/0046

at the core part 60, an inevitable release force is created on the corresponding part when the last Toilet paper sheet is peeled off. This causes the leftward axial movement of the core part and the resulting separation of parts 60 and 62 favors.

It can be seen that the roller carrier 58, despite it from several, axially aligned and butting core parts does not have the disadvantage of the known Facilities is afflicted, for example that according to US Pat. No. 3,214,014, because measures are provided that ensure that at least one of the Core parts shifts outwards in the axial direction when the toilet paper sitting on it is used, thereby ensuring that the core parts abutting one another actually separate from each other inside the roll holder.

A third embodiment in accordance with the invention, shown in FIG. 6, is similar in many respects to FIG ready described execution forms. In this embodiment, however, the roller carrier consists of core parts 70 and 72, the adjacent ends 71 and 73 of which have an axial spacing within the opening 16 in each In other respects, the embodiment corresponds to FIG that of Fig. 5

As a result of the between the adjacent ends 71 and 73 the core parts 70 and 72 existing axial distance, however, it is not necessary to have facilities within the Provide roll holder, which ensure that one of the core parts and its associated pin move in the axial direction outwards when the paper tape runs out of the roll carrier. After the toilet paper is substantially completely withdrawn from the core parts 70 and 72, rather fall because of the axial distance between the adjacent ends 71 and 73 the core parts only downwards out of the roll holder, as indicated by the arrows in FIG.

Thus, a corresponding roll holder for the embodiment after Pig. 6 consists only of single-slotted supports 74 and 76 with closed lower ends 75 and 77 exist. The closed ends 75 and 77 capture and deliver the inner portions 40 and 32, respectively, of the pins 28 and 26 thus a device for the rotatable mounting of the roll in the roll holder.

A fourth embodiment of the invention is shown in FIG reproduced and consists of a paper roll 10, which is on a roll carrier 80 of greater axial length than the length of the roll is wound. The roller carrier consists of two axially aligned core parts

The adjacent edges 71 and 73 of the core parts have an axial distance within the opening 16, so that after the paper has been used up on the core parts of the roll carrier 94 collapses and falls out of the corresponding roll holder.

A pin 96 is inserted into the end of the core part 70 adjacent to the end of the roller 10. In the other end the end of the core part 72 adjacent to the roller 10, a pin 98 is inserted. The pin 96 consists of an annular, with the core part internally engaging part 100 and an outwardly directed part 100 with the roll holder engaging portion 102. The outer portion 102 is smaller in diameter than the inner portion 100 and is formed in one piece with it by means of an annular collar 104. The collar sits somewhat inside the opening 16 within the corresponding ends of the core parts 70 or roller 10.

The pin 98 consists of a hollow, annular inner portion 106 engaging the core portion and an inner portion hollow, annular, outer part 108 engaging the roller holder. The outer part 108 is with the inner part 106 near the converging ends of core part 72 and roller 10. How to recognize from Pig .. 8 can, the inner diameters of the hollow parts 106 and 108 of the pin 98 are larger than the outer diameter of the outer part

102 of the pin 96 · Due to the inequality of the diameters of the parts 102 and the parts 106 and 108, the Part 102 of the roller carrier 94 in a first role can be taken up by the parts 106 and 108 of the roller carrier in a second role and the rollers can be thus stack end to end

The roll 10 of the embodiment of Fig. 8 can be held in a roll holder similar to that shown in FIG Fig. 6 is. This roll holder has two vertically slotted supports with closed lower ends for engagement with the outer parts 102 and 108 of the pins 96 and » 98 on.

The embodiments according to FIGS. 1, 5, 6, 7 and 8 each include a roll of toilet paper with an inserted roll carrier for inner support of the roll and for holding in a roll holder »whereby the roll carrier has a greater axial length than that carried by it In particular, as can be seen from the description of the exemplary embodiments listed above, the Roller carrier due to the inequality of the axial longitudinal extension clay roller and roller carrier suitable from one corresponding roll holder to fall out automatically as soon as the toilet paper sitting on the roll carrier is used up.

A modified pin 110 is shown in FIG. 9,

109886/0046 - 19 -

which can take the place of the pin 96 in the embodiment according to FIG. 8. The pin 110 is essentially similar to the pin 26 and 28, as in the embodiments according to the Pig. 1, 5 and 6 can be used and includes an outer core-engaging portion 112, an inner portion 112 with the ball holder in FIG Engaging part 114 and an annular web 116, which the parts 112 and 114 within the opening 16 and although it connects within the ends of core part 70 and roller 10. The outer part 112, the inner part 114 and the Web 116 delimit between them an annular recess 118 which opens axially outward from the pin 110.

The outer diameter of the part 114 of the pin 110 is smaller than the inner diameter of the parts 106 and 108 des ZapfL.ens 98, so that the part 114 of the parts 106 and 108 and the part 108 can be removed from the recess 118. Thus, roles can be carried out with the tenons 98 and 110 end to end like rollers with pins 96 and 98 stack.

If, however, the pin 110 takes the place of the pin 96 according to Fig. 8, then the outer diameter of the outer part must 108 of the pin 98 can be reduced somewhat compared to that of FIG. 8 in order to ensure that the outer part 108 of a first roller from the recess 118 of a

A suitable roll holder for receiving this roll contains support arms 130 and 132 which dtr at each end Roll are arranged. Conical spindles 134 ″ and 136 are rotatably mounted in the ends of arms 130 and 132.

The spindle 134 is in the one adjacent to the end of the roll 10 End of the core part 124 inserted · Similarly, the spindle I36 is inserted into that of the other end of the Roll 10 adjacent end of the core part 122 inserted. In this way, the roll 10 becomes rotatable in the roll holder stored so that the user can pull off the toilet paper as desired

Hachdem the toilet paper on the core parts 122 and 124 is essentially used up, the core parts detach from the spindles 134 and I36 and fall down, out of the reel seat as shown in dashed lines and through the parts in Pig. 10 is indicated.

A final embodiment of the invention to be discussed is shown in FIG. This embodiment contains a toilet paper roll 10 and a roll carrier 138 within the opening 16. The carrier 133 consists of a single roll part 140 _9, the axial length of which is less than the axial length of the roll 10. This roller carrier ends within the

Opening 16 each slightly inward from the ends of the Role 10.

A role according to this form of embodiment can be found in a roll holder, which is essentially similar to the roll holder according to Fig. 10. However, the truncated cone-shaped spindles 142 and 14-4 of the roll holder after yig. 11 a slightly larger diameter than that Spindles 134 and 136 of the previously described roll holder on »because the spindles 142 and 144 in the ends of the Opening 16 are used and are in direct contact with the Solletten paper roll 10 instead of one or several core parts as in the previous embodiment

Seeding the toilet paper essentially rom Kernten 140 is used up, the core part falls downward out of the roll holder.

The feature of the invention, which not only corresponds to the relatively simple execution forms according to fig. 10, and 11, but also common to the previously described embodiments, is that the inner Roll carrier in the paper roll has a different axial longitudinal extension than the roll it carries They run out shapes according to the Pig. 10 and 11 embody this · principle in combination with the use of a

Roller support β, which has a smaller axial length than the roller, while the Ausführungsformen 1, 5, 6, 7 and 8 embody this principle in combination with a roller carrier »its axial length is greater than that of the role it carries. However, according to all embodiments According to the invention, this inequality of the axial longitudinal extensions is the characteristic which gives it to the inner roller carrier makes it possible to automatically pull out all of the corresponding roll holder when the wound toilet paper or the like is essentially consumed rom the core is.

It can be seen that in the ^{embodiments of the invention reproduced in S 1} Ig * 7-10 and 11, this result is achieved by a roller carrier made of one or more core parts which are offset in the axial direction with respect to the ends of the roller carried by them.

A similar result is achieved in the embodiments according to I ¹ Ig. 1, 5, 6 and 8 by using pins which protrude axially outward beyond the ends of the roller. Thus, in these latter embodiments, the ends of the questioning devices, which also contain the pins, are displaced axially with respect to the roller ends. The axial displacement of the ends of the roll carrier over the ends of the roll sitting above it
