Description
1~28431 A PAPER TOWEL DISPENSER NOZZLE HAVING A
FLANGE AND A CONICAL FUNNEL
The present invention relates to a dispenser nozzle for a paper towel container, and more particularly to a dispenser nozzle which allows a paper towel to be separated along a perforation boundary from a following paper towel after a leading portion of the following paper towel has exited from the nozzle.
Paper towels are extremely popular for cleaning, absorbing, and many other well known uses. Typically, paper towels are supplied from the manufacturer as a rolled continuous web of paper sheets. Thus, each paper towel is separated from 15 its neighbor by a perforated area, or an area of weakened structure. This permits the user to tear one or more paper towels from the roll. However, it is well known that the quality of perforations varies widely from manufacturer to manufacturer, 20 thus making the tearing operation inexact. The phenomonon of half-torn paper towels is familiar to all paper towel users. Therefore, it has become popular to supply paper towel users with paper towel dispensers which can carry the roll of ~aper towels 25 and ease the tearing operation. ~owever, known paper towel containers still do not provide a sufficiently accurate structure to ensure a reliable and accurate tear.
Many proposals have been made in order to 30 provide structure for accurately separating one towel from another in a continuous web of perforated towels. For example, U.S. 4,262,816 to Margulies discloses a container and dispensing plate for a roll of premoistened towelettes. Figures 6-11 of ~ ,' ~, ..
~328~31 this patent disclose a thin, flexlble dispenser plate which is placed on top of a roll of towels.
The dispenser plate may be formed in a conical shape with an aperture at the tip thereof. The aperture is large enough to allow the towe ettes to be drawn therethrough, and at the same time provides enough friction to the web of towels so ~hat each towelette will separate at the perforation 2S it is pulled through the aperture. However, a difficulty in this 10 construction is that the then dispenser plate is allowed to float freely on top of the paper towel roll. Several flaps in the container assembly are folded over the conical dispenser plate in order to arrest the movement of the conical dispenser plate 15 as the user pulls up on a towel. This floating dispenser plate may become wedged in an improper position and obstruct the dispensing of towels from the container. In addition, the numerous contacts between the conical dispenser plate and the flaps 20 causes wear and subsequent distortion to each of these members, especially the thin dispenser plate. This eventually reduces the accuracy and reliabilility of the towel dispenser. In addition, the conical dispenser plate of ~argulies is 25 assembled by placing a slit in a thin, flat disk and then overlapping portions of the disk. Therefore, a separation exists between various portions of the conical structure. Dispensing towels may be caught in this separation and thus jam the dispenser.
30 Furthermore, paper towels may be caught and snagged at the separation, thus causing tearing o~ the towel at an unperforated section. Finally, the construction of the dispenser plate according to Margulies requires assembly by a user and constant 35 movement from one dispenser to ar.other. Therefore, -.~.
~' 1328~31 the conical dispenser plate of Mazgulies is not adaptable for industrial use and other high volume paper towel uses.
Several other examples of previously patented towel dispensers include: U.S. patent 4,180,160 to Ogawa et al., wherein a flexible dome structure is used to dispense the towels while retaining moisture within the container; U.S. patent 1,878,399 to Hope, wherein a wide-mouth, neck strip 10 dispenser causes folded towels to tear along their perforations; U.S. patent 4,648,530 to Granger, wherein a circular, venturi-shaped dispensing nozzle is used to dispense rolled paper products; and U.S.
patent 843,579 to Burr et al., wherein rolled paper 15 products are dispensed from a contoured mouth assembly. While all of these known dispensers seem to function adequately, there all have drawbacks.
The major drawback common to all known dispensers is that they currently require expensive materials for 20 forming the package, much hand labor, and ultimate disposal of the spent dispenser. In addition, each of the known dispensers has a fixed hole therein so that only one size of paper towels may be dispensed therethrough. For example, it is known that paper 25 towels come in one-ply, two-ply, and ev~en three-ply configurations. Thus, a dispenser for a one-ply towel would be unusable for a three-ply towel.
Therefore, what is needed is a simple pre-formed dispenser nozzle capable of being affixed to 30a paper towel container in order to reliably and accurately dispense paper towels so that each towel separates along its perforation boundary.
'~ .
1328~31 SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a novel, non-obvious dispenser nozzle apparatus for accurately and reliably dispensing a continuous web of rolled paper towels.
This ~nd other objects of the invention are achieved by providing a dispenser nozzle for a paper towel container holding a roll of perforated paper towels. A circular flange includes means for coupling the flange to the paper towel container.
10 Integral with the flange is a conical-shaped funnel for passing the paper towels therethrough. The conical shape causes each paper towel to be compressed as it moves along the funnel. The friction between the paper towel and the inside of 15 the funnel eventually cause the paper towel to be separated from its neighbor along the perforation boundary therebetween. ~owever, the breaking at the perforation boundary does not occur until a leading portion of the following paper to~el has exited from 20 the funnel. Thus, the user has a readily available portion of the following paper towel to grasp for the next operation.

DETAILED DESCRIPTION OP THE
PRESENTLY PREFERRED EXEMPLARY EMBODIMENT
While this invention is described with respect to a dispenser nozzle for a paper towel container, those of ordinary skill in this field will readily perceive that the teachings of this invention may be adapted to other dispensers. The 15 adaptation of the present invention to such other dispensers is to be included within the scope of the appended claims.
FIGURE 1 shows a paper towel roll 2 contained within a paper towel container 4 which has 20 a base member 6. Nozzle 8 is coupled to base 6 so as to protrude therefrom. A first paper towel 10 is dep,icted exiting the nozzle 8 while a following paper 12 is shown unwrapping from roll 2 and entering nozzle 8.
FIGURE 2 is a top view of nozzle 8 and depicts the circular flange 14 and the frusto-conical funnel 16. The bottom of the funnel includes an opening 18 which is preferably circular in shape and sized so that first paper towel 10 will 30 reliably separate from following paper towel 12 after a leading portion of paper towel 12 exits from opening 18.
.~
.~
6 1328~31 The top portion of funnel 16 includes an opening 20 which is sized to appropriately accept the insertion of paper towel 12.
Also visible in FIG~RE 2 are flexible support members 22 which are used to couple the flan~e 14 to the paper towel container base 6.
Support me~bers 22 are preferably flexible, acutely bent projections so that the nozzle 8 may be easily and removably snapped into base 6. The bent 10 projections 22 flexibly move in a radial direction with respect to a longitudinal centerline of said nozzle. Base 6 has an appropriately shaped opening to engage the support members 22 to lock the nozzle 8 onto base 6. Those having skill in this field 15 will recognize that any convenient and reliable means of coupling the nozzle 8 to the base 6 may be used in this invention. For example, a snap-ring, clips, or other known means may be readily adapted to connect nozzle 8 to base 6.
FIGURE 3 depicts a cross-sectional view of nozzle 8, taken along line 3-3 of FIGURE 2. FIGURE
3 depicts the nozzle dimensions believed appropriate to provide accurate and reliable separation of one paper towel from another. For example, the diameter 25Of opening 18 is set at 9/32 of an inch~ in order to reliably separate first paper towel 10 from following paper towel 12. The length of the nozzle is approximately 2 and 3/16 inches, with the diameter of opening 20 being approximately 15/16 of 30an inch. With the above-described dimensioning of the entrance hole 20, exit hole 18, and the length of nozzle 8, it is believed that reliable separation of towels will occur at the perforation boundary therebetween. However, persons of ordinary skill in 3sthis field should understand that modification of . ~
the dimensions may be made without departing from - the spirit of the claimed invention.
FIGURE 3 also depicts a novel feature according to the present invention in which the , diameter of exit hold 18 may be v2ried in order to adjust nozzle 8 to accommodate a ~ide variety of paper towels. Therefore, indents 24 and 26 are formed in the outside surface of funnel 16 to create a plurality of removable sections therein. Thus, 10 the exit portion of funnel 16 has one or more narrow neck portions adapted for easy removal from the funnel. The operator merely removes (by cutting, clipping, or breaking, etc.) excess nozzle in order to adjust the inside diameter of opening 18. Thus, 15 detachable sections are included at the end of nozzle 16 to conveniently accommodate the different sizes and thicknesses of paper towels used. Persons of skill in the field will understand that the - varying of exit opening 18 may be accomplished with 20 adjustable structure such as a collapsable funnel which may be moved to increase or decrease opening 18 and then locked into place. Later r the adjustable structure could be moved to accommodate a different size of paper towel.
Preferably, nozzle 8 is const~cted as a single, integral, rigid, plastic piece capable of being formed by injection molding techniques. It is preferred that nozzle 16 is rigid in order to provide long life and reliable use for paper towel 30users.
FI5URES 1, 2, 3, and 4 depict projections 28 which are used to align nozzle 8 in base 6.
These projections 28 are formed on the bottom of flange 14 and engage alignment holes in base 6.
3sEach projection 28 fits within a corresponding .
.
recess in base 6 in order to provide proper alignment and structural rigidity between nozzle 8 and base 6. Depicted in FIGURES 2, 3, and 4 are stiffening members 30 which are used to stiffen projections 28 against wear and repeated stress.
These stiffening members are positioned between the outside of funnel 16 and each projection 28.
Likewise, flexible supports 22 may also include stiffening members 32 to provide long life 10 and support to flexible members 22.
In FIGURE 3 it is shown that funnel 16 may comprise a circular entry portion 16a and a conical funnel portion 16b. The portion 16a is positioned at the entrance to funnel 16 and acts to introduce 15 the paper towel into the nozzle 8. Then, cone-shaped funnel portion 16b acts to compress the paper towel as it travels from the entrance opening 20 to the exit opening 18. As the paper towel compresses, friction increases between the inside wall of cone-20 shaped portion 16b and the paper towel itself. Thisincreased friction increases the resistance force on the towel as it is extracted from exit opening 18.
Eventually, the friction between the paper towel and the funnel 16 reaches a point where the resistance 25 force on the towel exceeds the force re~uired to break the paper towel along its perforation boundary. When this happens, the first towel 1 - will be separated from following towel 12.
FIGURE 4 depicts a bottom view of nozzle 18 30 clearly showing projections 28, and stiffening members 30, 32.
FIGURE 5 depicts the nozzle according to the present invention in operation. As the operator pulls the first towel 10 from opening 18 of nozzle 35 8, the friction between following towel 12 and .~, , , ~ r 9 13`2843~
funnel 16 exceeds the force required to break _ perforation boundary 40 between first towel 10 and following towel 12. At such a point, first towel 10 separates and leaves a leading portion of following towel 12 exposed from exit opening 18. Thus, the operator can easily grasp the leading portion of following towel 12 for the next towel dispensing cperation. If the towels inside the container are two-ply towels and therefore thicker, the operator 10 may detach a portion of the exit end of funnel 16 at detent 26. Likewise, if a three-ply towel is to be dispensed, or if the one-or two-ply towels within the container are extremely thick, a further portion of the nozzle 16 may be removed at detent 24.
In the present embodiment, it is advantageous for the entire structure of nozzle 8 to be symmetrical with respect to a longitudinal axis passing therethrough. This ensures that reliable towel dispensing may be conducted from any angle or 20 any position with respect to the towel container.
It is also preferable that the nozzle 8 be constructed of a translucent or transparent material so that any obstructions or malfunctions can be readily recognized without disassembling the nozzle 25 from the container.
Thus, what has been described is a compact, reliable, rugged and accurate towel dispenser capable of dispensing a wide variety of paper towels from any desired position. The nozzle can be easily 30snapped into a paper towel dispenser, or removed therefrom for maintenance or replacement.
Furthermore, the unitary construction of the flange and nozzle ensures a long life and accurate towel dispensing.
----~ hile the present invention has been described in what is believed to be the most practical and preferred embodiments, it is to be understood that the teachings of this invention encompzss all modifications and equivalen.
structures capable of performing the func.ions outlined by the following claims.

DETAILED DESCRIPTION OP THE
PRESENTLY PREFERRED EXEMPLARY EMBODIMENT
While this invention is described with respect to a dispenser nozzle for a paper towel container, those of ordinary skill in this field will readily perceive that the teachings of this invention may be adapted to other dispensers. The 15 adaptation of the present invention to such other dispensers is to be included within the scope of the appended claims.
FIGURE 1 shows a paper towel roll 2 contained within a paper towel container 4 which has 20 a base member 6. Nozzle 8 is coupled to base 6 so as to protrude therefrom. A first paper towel 10 is dep,icted exiting the nozzle 8 while a following paper 12 is shown unwrapping from roll 2 and entering nozzle 8.
FIGURE 2 is a top view of nozzle 8 and depicts the circular flange 14 and the frusto-conical funnel 16. The bottom of the funnel includes an opening 18 which is preferably circular in shape and sized so that first paper towel 10 will 30 reliably separate from following paper towel 12 after a leading portion of paper towel 12 exits from opening 18.
.~
.~
6 1328~31 The top portion of funnel 16 includes an opening 20 which is sized to appropriately accept the insertion of paper towel 12.
Also visible in FIG~RE 2 are flexible support members 22 which are used to couple the flan~e 14 to the paper towel container base 6.
Support me~bers 22 are preferably flexible, acutely bent projections so that the nozzle 8 may be easily and removably snapped into base 6. The bent 10 projections 22 flexibly move in a radial direction with respect to a longitudinal centerline of said nozzle. Base 6 has an appropriately shaped opening to engage the support members 22 to lock the nozzle 8 onto base 6. Those having skill in this field 15 will recognize that any convenient and reliable means of coupling the nozzle 8 to the base 6 may be used in this invention. For example, a snap-ring, clips, or other known means may be readily adapted to connect nozzle 8 to base 6.
FIGURE 3 depicts a cross-sectional view of nozzle 8, taken along line 3-3 of FIGURE 2. FIGURE
3 depicts the nozzle dimensions believed appropriate to provide accurate and reliable separation of one paper towel from another. For example, the diameter 25Of opening 18 is set at 9/32 of an inch~ in order to reliably separate first paper towel 10 from following paper towel 12. The length of the nozzle is approximately 2 and 3/16 inches, with the diameter of opening 20 being approximately 15/16 of 30an inch. With the above-described dimensioning of the entrance hole 20, exit hole 18, and the length of nozzle 8, it is believed that reliable separation of towels will occur at the perforation boundary therebetween. However, persons of ordinary skill in 3sthis field should understand that modification of . ~
the dimensions may be made without departing from - the spirit of the claimed invention.
FIGURE 3 also depicts a novel feature according to the present invention in which the , diameter of exit hold 18 may be v2ried in order to adjust nozzle 8 to accommodate a ~ide variety of paper towels. Therefore, indents 24 and 26 are formed in the outside surface of funnel 16 to create a plurality of removable sections therein. Thus, 10 the exit portion of funnel 16 has one or more narrow neck portions adapted for easy removal from the funnel. The operator merely removes (by cutting, clipping, or breaking, etc.) excess nozzle in order to adjust the inside diameter of opening 18. Thus, 15 detachable sections are included at the end of nozzle 16 to conveniently accommodate the different sizes and thicknesses of paper towels used. Persons of skill in the field will understand that the - varying of exit opening 18 may be accomplished with 20 adjustable structure such as a collapsable funnel which may be moved to increase or decrease opening 18 and then locked into place. Later r the adjustable structure could be moved to accommodate a different size of paper towel.
Preferably, nozzle 8 is const~cted as a single, integral, rigid, plastic piece capable of being formed by injection molding techniques. It is preferred that nozzle 16 is rigid in order to provide long life and reliable use for paper towel 30users.
FI5URES 1, 2, 3, and 4 depict projections 28 which are used to align nozzle 8 in base 6.
These projections 28 are formed on the bottom of flange 14 and engage alignment holes in base 6.
3sEach projection 28 fits within a corresponding .
.
recess in base 6 in order to provide proper alignment and structural rigidity between nozzle 8 and base 6. Depicted in FIGURES 2, 3, and 4 are stiffening members 30 which are used to stiffen projections 28 against wear and repeated stress.
These stiffening members are positioned between the outside of funnel 16 and each projection 28.
Likewise, flexible supports 22 may also include stiffening members 32 to provide long life 10 and support to flexible members 22.
In FIGURE 3 it is shown that funnel 16 may comprise a circular entry portion 16a and a conical funnel portion 16b. The portion 16a is positioned at the entrance to funnel 16 and acts to introduce 15 the paper towel into the nozzle 8. Then, cone-shaped funnel portion 16b acts to compress the paper towel as it travels from the entrance opening 20 to the exit opening 18. As the paper towel compresses, friction increases between the inside wall of cone-20 shaped portion 16b and the paper towel itself. Thisincreased friction increases the resistance force on the towel as it is extracted from exit opening 18.
Eventually, the friction between the paper towel and the funnel 16 reaches a point where the resistance 25 force on the towel exceeds the force re~uired to break the paper towel along its perforation boundary. When this happens, the first towel 1 - will be separated from following towel 12.
FIGURE 4 depicts a bottom view of nozzle 18 30 clearly showing projections 28, and stiffening members 30, 32.
FIGURE 5 depicts the nozzle according to the present invention in operation. As the operator pulls the first towel 10 from opening 18 of nozzle 35 8, the friction between following towel 12 and .~, , , ~ r 9 13`2843~
funnel 16 exceeds the force required to break _ perforation boundary 40 between first towel 10 and following towel 12. At such a point, first towel 10 separates and leaves a leading portion of following towel 12 exposed from exit opening 18. Thus, the operator can easily grasp the leading portion of following towel 12 for the next towel dispensing cperation. If the towels inside the container are two-ply towels and therefore thicker, the operator 10 may detach a portion of the exit end of funnel 16 at detent 26. Likewise, if a three-ply towel is to be dispensed, or if the one-or two-ply towels within the container are extremely thick, a further portion of the nozzle 16 may be removed at detent 24.
In the present embodiment, it is advantageous for the entire structure of nozzle 8 to be symmetrical with respect to a longitudinal axis passing therethrough. This ensures that reliable towel dispensing may be conducted from any angle or 20 any position with respect to the towel container.
It is also preferable that the nozzle 8 be constructed of a translucent or transparent material so that any obstructions or malfunctions can be readily recognized without disassembling the nozzle 25 from the container.
Thus, what has been described is a compact, reliable, rugged and accurate towel dispenser capable of dispensing a wide variety of paper towels from any desired position. The nozzle can be easily 30snapped into a paper towel dispenser, or removed therefrom for maintenance or replacement.
Furthermore, the unitary construction of the flange and nozzle ensures a long life and accurate towel dispensing.
