Abstract
HOLDER FOR ROLLS OF PAPER
Abstract of the Disclosure A holder for a paper towel roll or toilet paper roll. A stationary base member has an annular flat rim surrounding a central frustoconical projection. A rotatable member also has an annular flat rim surrounding a central hollow frustoconical projection that nests around the projection of the base member and is rotatable with respect thereto. The facing flat surfaces of the rim and the facing surfaces of the projections enable relative rotation with some resistance, to provide braking action. The outer surface of the frustoconical projection of the rotatable member includes means, such as splines, for firmly non-rotatably engaging the hollow core of a paper towel roll or toilet paper roll. The base member is secured horizontally, so that the rotatable member stands up vertically and holds the paper roll vertically.

Description
3~`~
Background of the Invention This invention relates to a holder for a roll of paper, such as a paper towel roll or a toilet paper roll, by which l:he roll is held vertically.
Current paper towel holclers are in many instances unsatisfactory. They ; hold the roll horizontally and in order to do so are secured to a wall or other similar surface. Often, this means that they cannot be placed closely ad~acent the place where they are needed. Many such devices are also inconvenient in that they require two-hand operation. Some holders fail to hold the paper rolls snugly enough, so that the rolls tend to Eall out.
An important object of the present invention is to provide a holder for paper towels which can be held by any suitable horizontal or vertical surface and which holds the paper towel roll vertically. Such a device enables easy one-hand operation and is adaptable for many locations where horizontally-held rolls are not conveniently supported.
Advantages of the invention will appear from the following description of preferred embodiments thereof. The roll is very easily installed and removed.
Both paper towels and toilet paper, when held horizontally, normally require an installation which is somewhat time-consuming and sometimes very much so. With the present holder, installation is a matter of two or three seconds and the removal takes even less than that.
Summary of the Invention The invention provides a two-piece paper towel roll holder, including in combination: a stationary-base member of high-impact plastic having an annular rim surrounding a central hollow frusto-conical projection, said rim having an upper surface on the same side as said projection, a rotatable member of high-impact plastic having an annular rim surrounding a central hollow pro-jection that nests around the outer surface o~ the hollow projection of said base member in surface engagement therewit}l and is rotatable with respect there-. . .

1 Description of Preferred Embodiments 2 The Embodiment o Figs. 1-5:
3 Figs. 1 to 5 show a plastic paper-roll holder 10 4 which can hold vertically either a roll 11 of paper towels S or a roll of bathroom toilet tissues, the roll 11 having a 6 cylindrical hollow cardboard core 12 (Fig. 5). A preferred 7 plastic is high-impact polystyrene.
9 The holder 10 comprises two main members, namely, a stationary plastic base 13 and a rotatable upper plastic ;
11 paper-holding member 14.
13 The base 13 comprises a generally flat circular 14 plastic annulus or rim 15~ preferably about l/12 inch thick, and a central protrusion 16 which may, for example, be about 16 1-1/4 inch in diameter, about 1/12 inch thick, and extend 17 about 2-1/4 inches high. The base 13 is provided so that 18 its upper surace 17, both of the rim 15 and the outer 19 surface 18 of the protrusion 16, presents low enou~h friction-to enable rotation of the upper member 14, but enough friction 21 to apply some braking action. Instead of being smooth, as 22 shown, there may be one or more circumferential ribs, if 23 desired, to help in achieving this controlled rotary motion, 24 with braking, but with many plastics this is achieved with smooth surfaces, as it is with high-impact polystyrene.
26 Thus, the upper surface 17 of the rim 15 and the surface 18 27 of the protrusion 16 provide surfaces on which the member 14 28 can freely rotate with some b~aking. Preferably, the 29 protrusion 16 is frustoconical, at an angle of about 1 or 2, e.g., 120'.
32 Preferably, the rim 15 has a downwardly extending 33 outer circumferential lip 19, and a lower surface 20 of the 34 rim 15 has a disc 21 (preferably three inches in diameter) of two-way adhesive secured to it. This disc 21 is 36 preferably made of a sheet 21a of 1/16" white plastic foam 37 (e.g.,polyethylene ) coated on both sides with strong adhesive 38 22,23; it may come as a separate element when sold, with wax ,.~

1 Description of Preferred Embodiments 2 The Embodiment o Figs. 1-5:
3 Figs. 1 to 5 show a plastic paper-roll holder 10 4 which can hold vertically either a roll 11 of paper towels S or a roll of bathroom toilet tissues, the roll 11 having a 6 cylindrical hollow cardboard core 12 (Fig. 5). A preferred 7 plastic is high-impact polystyrene.
9 The holder 10 comprises two main members, namely, a stationary plastic base 13 and a rotatable upper plastic ;
11 paper-holding member 14.
13 The base 13 comprises a generally flat circular 14 plastic annulus or rim 15~ preferably about l/12 inch thick, and a central protrusion 16 which may, for example, be about 16 1-1/4 inch in diameter, about 1/12 inch thick, and extend 17 about 2-1/4 inches high. The base 13 is provided so that 18 its upper surace 17, both of the rim 15 and the outer 19 surface 18 of the protrusion 16, presents low enou~h friction-to enable rotation of the upper member 14, but enough friction 21 to apply some braking action. Instead of being smooth, as 22 shown, there may be one or more circumferential ribs, if 23 desired, to help in achieving this controlled rotary motion, 24 with braking, but with many plastics this is achieved with smooth surfaces, as it is with high-impact polystyrene.
26 Thus, the upper surface 17 of the rim 15 and the surface 18 27 of the protrusion 16 provide surfaces on which the member 14 28 can freely rotate with some b~aking. Preferably, the 29 protrusion 16 is frustoconical, at an angle of about 1 or 2, e.g., 120'.
32 Preferably, the rim 15 has a downwardly extending 33 outer circumferential lip 19, and a lower surface 20 of the 34 rim 15 has a disc 21 (preferably three inches in diameter) of two-way adhesive secured to it. This disc 21 is 36 preferably made of a sheet 21a of 1/16" white plastic foam 37 (e.g.,polyethylene ) coated on both sides with strong adhesive 38 22,23; it may come as a separate element when sold, with wax ,.~

., l or treated paper covering the surface of both its upper 2 adhesive layer 22 and its lower adhesive layer 23, or the 3 upper adhesive layer 22 may be adhered pr~or to sale to .-~ the bottom surface 20 of the rim 15. The foam 21a provides
5 a desired resiliency, withstanding shock, and also enables
6 clean removal from a counter, by forcing a blunt knife into
7 the foam and lif-ting up the base 13; the foam 21a is then
8 sheared apart, and the adhesive 23 and ~he foam portion
9 remaining with that are readily removed by a solvent, such
10 as alcohol. In place of this convenient adhesive disc 21,
11 which is preferably slightly thicker than the lip 19, e.g.,
12 1/16" for a lip thickness of about 1/20 inch, the device
13 may be supplied without such a disc, and the user may either
14 apply adhesive such as cement or may use screws with screw
15 holes being provided in the rim, but the disc 21 has
16 advantages that will be seen. The disc 21, or other suitable
17 means, is then used to secure the base 13 to a suitable
18 countertop 24, or other horizontal surface. Use of adhesive
19 makes it possible to adhere it to any countertop whether of ~0 wood, plastîc, "Formica~", tile porcelain, or metal, without 21 drilling any screw holes. In any event, the base 13 is then 22 held stationary.
24 The upper rotatable plastic member 14 has an 25 annular flat rim 25 about 1/10 inch thick and a central 26 protrusion 26 which is preferably frustoconical to match the 27 frustoconical protrusion 16, but, if desired, only the outer 2~ surface 27 of the protrusion 26 may be frustoconlcal. It 29 preferably extends about 3 inches high and about 1/10 inch 30 thick and has a gradation in diameter from about 1.5 inch 31 at the bottom to about 1.4 inch at the top. This is an angle 32 of about 1 or 2, e.g., 120'. The purpose of this is to 33 enable it to accommodate the various sizes and tolerances 3~ within those sizes of paper towel and tissue rolls 11 as 35 they are made. The gradation of the central protrusion 26 ~D 36 enables it to accept all the now-manufactured cylindrical ; D 37 paper rolls or towels and tissues.

' ' : :
1 While this ou~er surface 27 may be relatively ~ smooth, it should not be slippery, for it is intended to 3 create a grabbing effect on the core 12 of the paper towel 4 roll 11. To augment this grabbing e~Eect, the protruslon 26 may be provided with a series of axially-extending 6 projecting splines 28, although these are not essential.
7 Also, other types of seizing devices may be used. Since some paper towel cores 12 are-substantially larger interiorly ~ than others (See, for example, the core 12c. of the roll lla~, it is also preferred that the external surface, at least, 11 of t~e protrusion 26 have a step 30 near its lower end.
12 For ~xample, this step 30 may be about 1/4 inch high and 13 about l/8 inch wide, to give the portion below the step 30 14 a diameter of about 1.64 inch. There may be 12 splines 31 below the step 30, each measuring approximately a 114 inch 16 in length and each about 1/200 inch high. The protrusion 17 26 above the step 30 may have similar rigid splines 28.
18 These may be placed as the points of a clock, for example, 19 30 apart.
21 l~hen assembled, the upper surface 17 of the rim 15 22 engages the lower surface 32 of the rim 25, while the outer 23 surface 18 of the protrusion 16 engages the inner surface 33 24 of the protrusion 26. These engaging surfaces 17,32 and 18,33 may be smooth but not slippery. ~ circular rib may be 26 present on one or more similar surface, but is not necessary, I
27 so long as good rotation and good braking action are assured, 28 as they are by smooth, unslippery surfaces.
The upper ends 34 and 35 of both protrusions 16 31 and 26 may be solid. Preferably, they are slightly domed, 32 as shown, and may, for molding convenience be shaped to 33 provide a central dimple 36 or 37.
It will be evident that the device of this inven-36 tion is readily installed and that the rotatable member 1 37 is also freely removable from the base member 13. This .

l need not always be the case, but it is convenient, In this 2 way, it may be removed for installation of a new paper towel 3 roll 11 or for removing an old one, or the core 12 of an 4 exhausted roll ll may be simply pulled off the device or stripped from it in any suitable way and the new one placed 6 on it. Usually with a slight push being sufficient ~o assure 7 full seizure.
9 Once thé paper roll is installed vertically, towels are usually removed, either one at a time or as a series, 11 and the same thing applies to bathroom tissues. The roll 11 12 is held against rotation relative to the me~iber 14 by 13 installing its core 12 around the protrusion 26 until the 14 roll 11 is fully seized by the member 14. When the member 14 is then reinstalled in the member 13, pulling a towel will 16 cause the upper member 14 (and its roll 11) to rotate 17 relatively to the base member 13, while there is sufficient 18 braking action, so that a towel may be torn off th~ roll 19 11 without causing the member 14 and roll 11 to continue rotation and unwind unwanted towels.
22 The Embodiment of Figs. 6 to 10:
23 A plastic roll holder 50 o~ Figs. 6 and 7 includes 24 a stationary plastic base 51 and a rotatable member 52.
The base 51 is generally like the base 13, having a rim 53 26 with an upper surface 54 and a central hollow frustoconical 27 protrusion 55 with an outer surface 56. There is also a 28 lower surface 57, preferably surrounded by an annular lip 29 58 and with an adhesive carrying plastic foam disc 59 secured thereto by an upper adhesive layer 59a, preferably 31 with a non-adhesive sheet 59c covering its lower adhesive 32 layer 59b and removable before installation.
34 The rotatable member 52 has a flange or base 6 up from which a protrusion 61 extends. There is a lower 36 surface 62 and an upper surface 63 o the flange 60, and 37 the hollow protrusion has an inner surface 64 and an outer ."
1 surface 65, as well as an upper closed cap portion 66. The 2 ~ inner surface 64 is generally frustoconlcal with an offset 3 portion 67 near the flange 60. The out:er surface 65 is also ~ generally frustoconical, but is provided with a series of S steps of gradually decreasing diameter. Thus, there may be 6 a lowest smooth frustoconical portion 70 which mee~s the 7 flange 60, followed by a radially inward step 71 to a second 8 smooth frustoconical portion 72, followed by another step 9 73 to a third smooth frustoconical portion 74, which is succeeded by an inner step 75 leading to a fourth smooth 11 frustoconical portion 70, and the fourth portion 76 ends at 12 an inward step 77 leading to the remaining smooth frusto-13 conical portion 78 of the protrusion 61. This enables taking 14 a number of different sizes of paper-towel cores. In this particular form of the invention there are no further 16 projections like the splines 28, though there may be, if 17 desired.

On occasions, co~ntertop space is not available, 21 and yet it is possible to provide a device having most of 22 the advantages of the invention but suitable for wall mounting.
23 Figs. 11-13 show such applications of the invention. Again, 24 an assembly 80 may be made in two main pieces, as sho~n in Figs~ 11 and 12, both of which may be molded plastic, such ~6 as high-impact polystyrene. In this instance, the assembly 27 80 comprises a base member 81 and an upper rotatable member 28 82.
The base member 11 includes a vertically-extending 31 flange 83 which may be attached either by adhesive 84 or 32 by screws 85 (Fig. 1~) or by both (Fig. 11), the screws 85 33 extending through openings 86 provided in the vertical 3~ flange 83. The flange 83 is molded integrally with the remainder of the base 81 which also provides a shelf-like 36 portion 87, much wider than the bases heretofore discussed, 37 since such a base will have to accommodate the full ou~side 38 width of the paper roll 88 (See Fig. 11). It is, therefore, . ,, , ,' " ' , ' ' 3~, 1 made large and may be, for example, 6-1/2 inches in diameter.
2 This acts, then~ to form its own shel~, The base 81, in 3 the form of the invention shown in Figs. 11 and 12 has an 4 upper surace 89, and a projection 90 ~hich is frustoconical and preferably about 2-1/2 inches high.
7 The rotatable member or spinclle 82 goes over the 8 projection 90 and supports the roll 88~ as heretofore. It 9 may be substantially exactly like any of the forms heretofore shown. The structure of its frustoconical projection 91 11 may be in any of the already described forms or may be a 12 somewhat different modification of them. Operation, so far 13 as the part between the stationary base 81 and the rotatable 14 spindle 82 are concerned, is that already described. If desired~ the protrusion 90 from the base 81 may be placed 16 off-cen~er, for the outer portion of the roll 88 may need 17 no extensive support.
19 If desired, as shown in Fig. 13, the base 81 may be made in two pieces, wi~h a shelf member 95 integral with 21 the flange 83, and a separate base member 96 adhesively 22 secured thereto and substantially like the bases previously 23 described.
To those skilled in the art to which this invention 26 relates, many changes in construction and widely differing 2~ embodiments and applications of the invention will suggest 28 themselves without departing from the spirit and scope of 29 the invention. The disclosures and the description herein are purely illustrative and are not intended to be in any 31 sense limiting.

24 The upper rotatable plastic member 14 has an 25 annular flat rim 25 about 1/10 inch thick and a central 26 protrusion 26 which is preferably frustoconical to match the 27 frustoconical protrusion 16, but, if desired, only the outer 2~ surface 27 of the protrusion 26 may be frustoconlcal. It 29 preferably extends about 3 inches high and about 1/10 inch 30 thick and has a gradation in diameter from about 1.5 inch 31 at the bottom to about 1.4 inch at the top. This is an angle 32 of about 1 or 2, e.g., 120'. The purpose of this is to 33 enable it to accommodate the various sizes and tolerances 3~ within those sizes of paper towel and tissue rolls 11 as 35 they are made. The gradation of the central protrusion 26 ~D 36 enables it to accept all the now-manufactured cylindrical ; D 37 paper rolls or towels and tissues.
.~
' ' : :
1 While this ou~er surface 27 may be relatively ~ smooth, it should not be slippery, for it is intended to 3 create a grabbing effect on the core 12 of the paper towel 4 roll 11. To augment this grabbing e~Eect, the protruslon 26 may be provided with a series of axially-extending 6 projecting splines 28, although these are not essential.
7 Also, other types of seizing devices may be used. Since some paper towel cores 12 are-substantially larger interiorly ~ than others (See, for example, the core 12c. of the roll lla~, it is also preferred that the external surface, at least, 11 of t~e protrusion 26 have a step 30 near its lower end.
12 For ~xample, this step 30 may be about 1/4 inch high and 13 about l/8 inch wide, to give the portion below the step 30 14 a diameter of about 1.64 inch. There may be 12 splines 31 below the step 30, each measuring approximately a 114 inch 16 in length and each about 1/200 inch high. The protrusion 17 26 above the step 30 may have similar rigid splines 28.
18 These may be placed as the points of a clock, for example, 19 30 apart.
21 l~hen assembled, the upper surface 17 of the rim 15 22 engages the lower surface 32 of the rim 25, while the outer 23 surface 18 of the protrusion 16 engages the inner surface 33 24 of the protrusion 26. These engaging surfaces 17,32 and 18,33 may be smooth but not slippery. ~ circular rib may be 26 present on one or more similar surface, but is not necessary, I
27 so long as good rotation and good braking action are assured, 28 as they are by smooth, unslippery surfaces.
The upper ends 34 and 35 of both protrusions 16 31 and 26 may be solid. Preferably, they are slightly domed, 32 as shown, and may, for molding convenience be shaped to 33 provide a central dimple 36 or 37.
It will be evident that the device of this inven-36 tion is readily installed and that the rotatable member 1 37 is also freely removable from the base member 13. This .
.. . .
: ' ' ' ' .
:, .
l need not always be the case, but it is convenient, In this 2 way, it may be removed for installation of a new paper towel 3 roll 11 or for removing an old one, or the core 12 of an 4 exhausted roll ll may be simply pulled off the device or stripped from it in any suitable way and the new one placed 6 on it. Usually with a slight push being sufficient ~o assure 7 full seizure.
9 Once thé paper roll is installed vertically, towels are usually removed, either one at a time or as a series, 11 and the same thing applies to bathroom tissues. The roll 11 12 is held against rotation relative to the me~iber 14 by 13 installing its core 12 around the protrusion 26 until the 14 roll 11 is fully seized by the member 14. When the member 14 is then reinstalled in the member 13, pulling a towel will 16 cause the upper member 14 (and its roll 11) to rotate 17 relatively to the base member 13, while there is sufficient 18 braking action, so that a towel may be torn off th~ roll 19 11 without causing the member 14 and roll 11 to continue rotation and unwind unwanted towels.
22 The Embodiment of Figs. 6 to 10:
23 A plastic roll holder 50 o~ Figs. 6 and 7 includes 24 a stationary plastic base 51 and a rotatable member 52.
The base 51 is generally like the base 13, having a rim 53 26 with an upper surface 54 and a central hollow frustoconical 27 protrusion 55 with an outer surface 56. There is also a 28 lower surface 57, preferably surrounded by an annular lip 29 58 and with an adhesive carrying plastic foam disc 59 secured thereto by an upper adhesive layer 59a, preferably 31 with a non-adhesive sheet 59c covering its lower adhesive 32 layer 59b and removable before installation.
34 The rotatable member 52 has a flange or base 6 up from which a protrusion 61 extends. There is a lower 36 surface 62 and an upper surface 63 o the flange 60, and 37 the hollow protrusion has an inner surface 64 and an outer ."
1 surface 65, as well as an upper closed cap portion 66. The 2 ~ inner surface 64 is generally frustoconlcal with an offset 3 portion 67 near the flange 60. The out:er surface 65 is also ~ generally frustoconical, but is provided with a series of S steps of gradually decreasing diameter. Thus, there may be 6 a lowest smooth frustoconical portion 70 which mee~s the 7 flange 60, followed by a radially inward step 71 to a second 8 smooth frustoconical portion 72, followed by another step 9 73 to a third smooth frustoconical portion 74, which is succeeded by an inner step 75 leading to a fourth smooth 11 frustoconical portion 70, and the fourth portion 76 ends at 12 an inward step 77 leading to the remaining smooth frusto-13 conical portion 78 of the protrusion 61. This enables taking 14 a number of different sizes of paper-towel cores. In this particular form of the invention there are no further 16 projections like the splines 28, though there may be, if 17 desired.
19 The Embodiments of Figs. 11 to 13:
On occasions, co~ntertop space is not available, 21 and yet it is possible to provide a device having most of 22 the advantages of the invention but suitable for wall mounting.
23 Figs. 11-13 show such applications of the invention. Again, 24 an assembly 80 may be made in two main pieces, as sho~n in Figs~ 11 and 12, both of which may be molded plastic, such ~6 as high-impact polystyrene. In this instance, the assembly 27 80 comprises a base member 81 and an upper rotatable member 28 82.
The base member 11 includes a vertically-extending 31 flange 83 which may be attached either by adhesive 84 or 32 by screws 85 (Fig. 1~) or by both (Fig. 11), the screws 85 33 extending through openings 86 provided in the vertical 3~ flange 83. The flange 83 is molded integrally with the remainder of the base 81 which also provides a shelf-like 36 portion 87, much wider than the bases heretofore discussed, 37 since such a base will have to accommodate the full ou~side 38 width of the paper roll 88 (See Fig. 11). It is, therefore, . ,, , ,' " ' , ' ' 3~, 1 made large and may be, for example, 6-1/2 inches in diameter.
2 This acts, then~ to form its own shel~, The base 81, in 3 the form of the invention shown in Figs. 11 and 12 has an 4 upper surace 89, and a projection 90 ~hich is frustoconical and preferably about 2-1/2 inches high.
7 The rotatable member or spinclle 82 goes over the 8 projection 90 and supports the roll 88~ as heretofore. It 9 may be substantially exactly like any of the forms heretofore shown. The structure of its frustoconical projection 91 11 may be in any of the already described forms or may be a 12 somewhat different modification of them. Operation, so far 13 as the part between the stationary base 81 and the rotatable 14 spindle 82 are concerned, is that already described. If desired~ the protrusion 90 from the base 81 may be placed 16 off-cen~er, for the outer portion of the roll 88 may need 17 no extensive support.
19 If desired, as shown in Fig. 13, the base 81 may be made in two pieces, wi~h a shelf member 95 integral with 21 the flange 83, and a separate base member 96 adhesively 22 secured thereto and substantially like the bases previously 23 described.
