Description

A ROLL OF DISPOSABLE PIECES OF HYGIENIC PAPER FIELD OF THE INVENTION The present invention relates to rolls of disposable pieces of toilet paper and in particular to rolls of toilet paper and paper towels that allow the removal of a piece of paper to be used without the need to tear the paper before being used. Paper is used in many forms for hygienic purposes of a single moment There is a wide variety of paper towel packaging, from a simple roll of paper towels to high quality wet towels in packaging that allows the removal of a single towel At a time these packages are inefficient when they do not prevent unwanted disinherited wet towels or are expensive However, the toilet paper packaging on a long strip of paper rolled in itself with perforated lines at regular intervals to facilitate the tearing of pieces of cleaning paper, which are placed outside after use, is the most common type of toilet paper currently used available BACKGROUND OF THE INVENTION Such rolls of paper can be found in distributors of appropriate sizes such as toilet paper dispensers in bathrooms and distributors of paper towels near washbasins. Many efforts have been made to develop paper of superior qualities, that sometimes are even contradictory, such as the strength of the paper, dimensions, softness, absorption capacity and cleanliness and manufacturing cost Figure 1 is a schematic illustration of the prior art illustrating a roll of toilet paper 100 in a standard toilet paper dispenser 101. The paper roll 100 includes the toilet paper 10, which has perforated lines 11 at regular intervals that enable the tear in the desired places The toilet paper is a long continuous strip, long in comparison to its width, wound in an inner tube 12 As shown in the illustration, the inner tube 12 is placed on an arm 13 with a round section , which is part of the toilet paper distributor 101 When the toilet paper is pulled to expose a segment of paper for tearing, this arrangement allows the toilet paper 100 to rotate around the arm 13.

Figure 2 is a schematic illustration of the prior art illustrating a roll of continuous toilet paper 102 above which a cutting apparatus 20 is placed. This roll may have perforated lines across its width however this is not necessary since the peeling off of the paper 14 is done by properly pulling the paper 14 tightly towards the cutting apparatus, which is usually of a rigid and heavy metallic material. It could include a cutting knife or saw teeth 21 as shown in the illustration.

In many cases, the standard package of continuous paper in a roll from which the pieces can be torn to be used is inconvenient or even impossible to use. Since the release of paper in the desired places requires the use of both hands, the use of such rolls by disabled individuals who are not able to use a hand or individuals with disabilities with respect to the combined use of both hands for this purpose.

The use of such rolls of continuous paper is also problematic for observant Jews, already in accordance with the laws of Judaism, the tearing of paper is prohibited during the Sabbath and on holidays.

There is also a widely recognized need for and that it would be highly advantageous to have a roll of toilet paper with the same qualities as the previous popular art toilet paper and with an additional quality that allows the removal of pieces of toilet paper from it. with only one hand without the need to tear it.

Before explaining at least one embodiment of the invention in detail, it is understood that the invention is not limited in its application to the details of construction and arrangement of the components set forth in the following description or illustrated in the drawings.

Unless defined otherwise, all technical and scientific terms used in this document have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The materials, dimensions, methods and examples provided herein documents are illustrative only and are not intended to be limiting Now with reference to the drawings, Figure 3 is a schematic illustration of a state in the production of the roll of disposable pieces of toilet paper in accordance with a preferred embodiment of the present invention. The pieces of paper 21 are placed overlapping one another in one plane and subsequently joined by winding them in an inner tube 12 in a packaging as a roll 200, as will be described in the following The inner tube 12 can be made of various materials including cardboard Each piece of paper 21 which is designated to serve as toilet paper has geometrical dimensions The thickness is marked by the letter "t", the width by the letter "d" and the length by the letter "a" The length of the overlap section is marked by the letter "b" with the overlap of the paper 21 consisting of its entire width "d" The length of the end of the paper 21 without overlapping is marked by the letter "c" and can then serve for a convenient hold between the fingers of the users to be pulled out of the roll 200 The piece of paper 21 can have one or more lines of perforations 11 similar to those shown in Figure 1 or can be without any perforation anywhere As shown in this illustration, the pieces of paper are placed one on top of the other with a deviation of "c" between each piece so that the piece more lej ana is from the inner tube 12, the uppermost layer that is in this arrangement results in the packaging of the disposable toilet paper roll 200 as described in all the articles of this application including the specifications and claims as the packaging of winding in Figure 3A is a schematic illustration of a state in the production of the roll of disposable pieces of toilet paper in accordance with another preferred embodiment of the present invention. This state is identical to that described in Figure 3 more than the arrangement of pieces of paper. , so that the farthest piece is from the inner tube 12, the lowest layer that is in it. This arrangement results in the packaging of the roll of the disposable toilet paper pieces 200 as described in all the articles of this application including the specifications and claims as rolling packaging out Both inwardly winding and outwardly rolling packages may have an approximately equal measure of overlap through the entire roll 200 or may have different measurements of overlap in accordance with the location of each piece of paper 21 in the roll 200 The size of the pieces of paper 21 and the overlap measurements between the pieces can be determined in accordance with the test Figure 4 is a schematic illustration of several external pieces of paper 21 in a roll of disposable pieces of toilet paper 200 in accordance with a preferred embodiment of the present invention in inwardly wound packaging. The direction of the force of gravity is marked in the illustration by the letter "g". As shown in the illustration, the piece of paper 21c has almost a circular shape when viewed from the side, when a piece of paper 21a wraps one layer on top of the other and a piece of paper 21b is wrapped in an additional layer. A cin segment of each of the pieces 21a and 21b are suspended on the roll 200 in planes in accordance with the force of gravity. The length of this segment depends on the momentary rotation angle of the roll 200 with respect to its central axis. The next piece of paper to be removed is one whose length of suspension is the longest and in the example shown in this illustration, it is the piece of paper 21a. Pulling the next piece of paper in turn approximately downward or in any other appropriate direction causes a rotational movement of the roll 200 about its axis until the next piece of paper in turn is removed.

Figure 5 is a schematic illustration of a side view of the forces and moments exerted on the roll of disposable pieces of toilet paper 200 in a plane perpendicular to the axis. When the pulling force T is exerted on the next piece of paper 21a in turn, the moment force M is generated, causing the rotational movement of the roll 200 about its central axis through the point O. The magnitude of the moment M it depends on the magnitude of force T and the external radius r of the roll. This is under the condition that there is no sliding movement between the piece of paper 21a and the roll 200. In order to prevent this sliding movement, the piece of paper 21a needs to exert the essential moment M on the roll 200 which will rotate it in a speed corresponding to the movement of drag. There are several kinds of forces that the paper 21a can exert on the roll 200, including electrostatic forces and adhesive forces, however the main force is the frictional force whose size depends on the coefficient of friction and the normal force, perpendicular to the roll 200 in all points of contact with paper 21a. The illustration shows the normal force Fn exerted at the point in the Alpha angle with respect to the gravitational axis. Normal forces of various sizes can be exerted in the total area of contact between the next piece of paper in turn to pull 21a and the roll 200 and all are effectively exerted at the radius r from the center of the roll 200. The integration of these forces determines the size of the moment M. A primary source of normal forces is the severity of pieces of paper 21 by themselves.

Figure 6 is a schematic illustration of the roll of disposable pieces of toilet paper 200 in accordance with a preferred embodiment of the present invention, placed in a standard toilet paper dispenser 101 equipped with a spring 15 designed to increase the normal force exerted in the roll 200. The spring 15 is connected between the base of the distributor 14 and the arm 13, as described in Figure 1. The advantage of the increase of the normal force exerted on the roll 200 is that it allows the use of hygienic parts of paper 21 of length a, as shown in Figures 3 and 3A, which is less than what might be required in the case of a smaller normal force.

Figure 7 is a schematic illustration of the roll of disposable pieces of toilet paper 200 in accordance with a preferred embodiment of the present invention, in which a weight is placed to increase the normal force. The benefit of adding the weight is similar to the explanation in the normal force exerted on the roll 200 given with respect to Figure 6. In the present case, the weight is encircled to the location in which the pieces of paper are disconnected from the roll 200, enabling the use of even shorter pieces of toilet paper 21. The weight described in this illustration is cylindrical 16 on an axis whose distance from the central axis of the roll 200 is determined in accordance with the radius of change of the roll 200 , a radius that decreases in size as the pieces of paper 21 are consumed. The ability of the cylindrical weight 16 to rotate about the axis enables better rotational movement of the roll 200 without the weight interfering with the movement of the paper pieces 21.

Apparatus for increasing normal force as described in Figures 6 and 7 are good for both inward winding and outward winding packages.

Figure 8 is a schematic illustration of the roll of disposable pieces of. toilet paper 200, according to a preferred embodiment of the present invention, in inwardly wound packaging. The illustration shows the piece of toilet paper on turn 23 which will be the first piece to be pulled and removed from the roll 200 and the second piece 24 next in turn.

As shown in the test, both inwardly winding and outwardly winding packages have the qualities necessary to meet the need that the present invention achieves. The simple test can determine all the qualities of the roll of disposable pieces of toilet paper, including the geometrical dimensions of each piece of paper, the geometric dimensions of the roll of disposable pieces of toilet paper and the materials and textures that make up the pieces of the toilet paper .

Although the invention has been described in conjunction with the specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to cover all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
