Description

ABSORBENT PAPER PRODUCT THAT HAS AN ELEMENT IN RELIEF AS IDENTIFICATION SOURCE FIELD OF THE INVENTION The description relates to embossed absorbent paper products such as toilet paper, disposable handkerchief and paper towels and to methods for making such paper products.

BACKGROUND OF THE INVENTION Absorbent paper products are known, such as toilet paper, handkerchief and paper towels. These products are commonly used in homes, businesses, restaurants, stores and the like. The absorbent paper products often have embossment to provide an aesthetically pleasing appearance on an unexposed surface of the absorbent paper product. Embossing is also known to be useful in helping to bind multiple sheets of absorbent paper to form a multi-sheet absorbent paper product.

The methods for making absorbent paper products are also known. Typically, absorbent paper products are made by wet laying processes in which a fibrous slurry of cellulosic fibers is deposited on a forming wire and thereafter dried by known processes such as through-air drying, press felts and Yankee drum dryer. The absorbent paper products may be folded or unfolded absorbent paper products and may be coated after being dried in multiple layers, embossed and / or rolled.

The manufacturers of absorbent paper products want the consumers of these products to be able to distinguish between the varieties of absorbent paper products in the market. One way in which a manufacturer can distinguish its products from the products of other manufacturers is by the embossed designs and the relief pattern visible to the consumer. For example, in a rolled-up format, as is common in toilet paper and paper towels, the last turn of the absorbent paper product can be exposed and visible to a consumer. If the rolled absorbent paper product is wrapped in a package that is at least partially transparent, the embossed design pattern can be seen through the packaging. A consumer can make a decision when buying based on a preferred embossed design pattern.

When an absorbent paper product is in use, such as at a user's house, it can be difficult, if not impossible, for a person to identify the manufacturer and / or seller of the absorbent paper product. Sellers are not generally informed of the various embossed patterns used by various manufacturers / sellers. Since at the time of use, the absorbent paper product container is, rarely, close to check, if a consumer uses the absorbent paper product and likes it, the consumer has no way to easily find out, the manufacturer, the seller or, for example, a brand name.

Even if a consumer does not know the manufacturer of the absorbent paper product by its brand name, the consumer can be reminded while using the source of the paper product.

Accordingly, it would be desirable to have an absorbent paper product having a raised design pattern that facilitates the identification of a manufacturer.

Additionally, it would be desirable to have an absorbent paper product It has a pattern of relief design visible on the outer layer that facilitates the identification of a manufacturer.

In addition, it would be desirable to have a rolled absorbent paper product having an embossed design pattern visible on an outer layer that supports a user during the use of the product as identified by a manufacturer.

Furthermore, it would be desirable to have an absorbent paper product whereby, even if a consumer does not know the manufacturer of the absorbent paper product by his brand name, the consumer can be reminded during the use of the source of the paper product.

BRIEF DESCRIPTION OF THE INVENTION A rolled absorbent paper product is described. The rolled absorbent paper product includes an absorbent paper substrate having at least one sheet with an embossed pattern comprising two visually distinct relief design elements disposed in a plurality of predetermined positions, spaced apart along the sheet. The two relief design elements comprise a first embossed design element occupying all but at least one of the positions in a first repeating pattern, and a second relief design element occupying at least one of the non-embossing positions. occupied by the first relief design element. The second relief design element can be a word comprising a linear relief defining linear relief letters, each letter comprising an open area within the linear relief. The first and second relief design element may each have an embossed area of about 7% to about 25% and a difference in relief area relative to each other of less than about 10%.

DETAILED DESCRIPTION OF THE INVENTION In one embodiment, the present invention is an absorbent paper product having at least one sheet with an embossed pattern comprising two visually distinct relief design elements arranged in a plurality of predetermined positions, spaced apart along the product. The absorbent paper product can be a disposable tissue, toilet paper, paper towel, napkin or the like, and can be provided in the form of a roll, as is common in toilet paper and paper towels.

The absorbent paper of the absorbent paper product can be any of known absorbent paper, known for its use as a disposable tissue, toilet paper, paper towel, napkin or the like and will not be described in detail in the present description. By way of example, suitable absorbent paper for use in the present invention includes the absorbent paper used in currently sold disposable tissues including PUFFS® and KLEENEX®, currently sold toilet paper such as CHARMIN®, COTTONELLE®, ANGEL SOFT® and ULTRA NORTHERN®, paper towels currently sold such as BOUNTY®, VIVA® and BRAWNY®. Generally, any absorbent paper product made by papermaking methods, including wet lay and through air drying and which can be embossed, can be used in the present invention. Therefore, the description below is non-limiting with respect to the particular absorbent paper product to be embossed, the particular manufacturing method or the particular format (e.g., rolled or stacked / interleaved).

One embodiment of the present invention is shown in Figure 1, which shows a roll 10 of absorbent paper product 12. The absorbent paper product 12 shown in Figure 1 is a paper towel product that is wet laid, dried with air and folded, as known in the art, before applying relief with the pattern shown. The pattern shown in Figure 1 is only representative.

As shown in Figure 1, the absorbent paper product 12 can having two visually distinct relief design elements, a first relief design element 14, which in Figure 1 includes two concentric diamonds and a second relief design element 16, which in Figure 1 is in the form of the name of BOUNTY® brand. The first relief design element 14 can have any shape, design or combination of shapes and designs, and can be included with other raised elements, such as the waved linear design 18 formed from reliefs at relatively spaced points 20. Generally , the visually distinct relief design elements are design elements that can be distinguished, visually, as separate, distinct design elements, which can be arranged in a pattern substantially of regular repetition, as shown in Figure 1 (only one of the second relief design element 16 is formed in Figure 1). Accordingly, the relief design elements described in the present description are described as being representative only and virtually any relief design element may be used for the first or second relief design element.

As shown in Figure 1, a roll of absorbent paper product 10 having relief may include a relief design element that is an identifying source, i.e., a logo, a trademark or a brand name such as BOUNTY® , as shown in Figure 1. The brand name may be the second relief design element 16, and may be separated in any pattern at predetermined positions according to the present invention. Having the logo, trademark or brand name of the manufacturer and / or seller in relief on a visually distinct embossing element in an absorbent paper product ensures that the consumer or other user can easily identify the manufacturer and / or seller of the product. Absorbent paper product during use. Therefore, the consumer of the manufacturer and / or seller can be remembered and the value of the manufacturer's and / or seller's brand can be reinforced to the consumer.

If the consumer likes the absorbent paper product, he or she can be reminded during the use of the source, and they may be better informed to make the same purchase the next time he or she purchases absorbent paper products.

Figure 2 shows a portion of a product web of absorbent paper 12. The product of absorbent paper 12 can be made in papermaking machines by wet laying, which as it is known, in commercial operations produce rolls of the paper product absorbent having an MD machine direction and a CD cross direction. The MD represents the direction of travel, while the absorbent paper product is made in the paper machine. The CD represents the transverse direction, which at its maximum, is the width of the paper web while it is being made (or the width of a finished paper product, such as a paper towel). The absorbent paper product 12 may have separate brittle lines 24, which may be in the form of perforations which in the finished product facilitate tearing off one sheet at a time. For example, rolled absorbent paper products such as toilet paper and paper towels typically have perforations that allow the user to tear a sheet (or a plurality of sheets) at the location of the perforation. Additionally, the master roll can be cut by a cutter to produce a plurality of finished rolls of a predetermined width. As shown in Figure 2, the cutter can cut lines 32 to form a finished roll having a roll width W.

The solid lines 34 forming two adjacent rectangles in Figure 2 are intended to represent two adjacent, individual sheets 36 of a roll of finished absorbent paper product such as a finished roll of paper towels in a Select-a-Size® format. Each sheet 36 is defined in the CD by the configurations of the cutter that cuts the mother roll and in the MD by the space of the lines of fragility 24.

As shown in Figure 2, the relief design elements occupy positions 22 which can be predetermined positions, each position can be occupied by a first relief design element 14, or a second relief design element 16, or non-element. of embossed design. In one embodiment, the positions 22 can be determined by the use of a screen 26, which can be imaginary or digitally superimposed, the screen that does not actually appear on the absorbent paper product 12, but can be a tool for conceptualizing and design an embossed pattern. A portion of a representative sieve 26 was shown in Figure 2. As shown, a screen 26 of the present invention may be a strand of parallel straight lines 28 in the machine direction, MD, intersecting with parallel straight lines in cross direction, CD. In a shown embodiment, the positions 22 are predetermined to be any intersection in the MD and the CD. For clarity, the positions 22 may be any predetermined location in the absorbent paper product 12 in which a designer desires a raised design element. In practice, it may be typical to make such design elements in a regular pattern of repetition. In the present invention, a first relief design element 14 can be arranged in a repeating pattern, substantially regular in most positions 22, with the exception of the positions 22 in which the second relief design elements are arranged. 16 The concept and description of "positions" as used in the present description is used to convey the enabling concept of a predetermined distribution of the relief design element that can be used in commercial relief equipment as is known in the art. Known relief rollers typically provide a gripping line between a rubber roller and a steel roller or two steel rollers. By Of course, all the ways of roller types, number of rollers, materials and grip line configurations can be employed in the present invention. However, to be commercially viable the roll for pattern relief can be balanced; that is, the pattern can be designed so that the area occupied by the relief elements is substantially equal as a percentage along the face of the relief roller. In one embodiment, for a specific area surrounding each position, the relief design element (and portions of relief elements) encompassed in that area has a relief area that is substantially equal to the relief area of the specific area. in any other position 22 having relief elements. Therefore, the number of positions is not important, but the spacing and location can be designed to ensure that on average, the relief area surrounding each position 22 is substantially equal along the face of the relief roller .

In one embodiment, therefore, in the present invention, the first relief design element 14 and the second relief design element 16 can have substantially equal relief areas in relation to each other, so that when they generally move away regularly in a pattern of repetition in some or all of the positions 22, the relief roller can be balanced. A balanced roll for relief experiences less wear and therefore lasts longer with a few other mechanical problems such as excessive vibration than an unbalanced roll.

In one embodiment, the first and second relief design element (together with any other relief element such as reliefs at closely spaced points 20 in a predetermined area, as described, below) each has an embossed area of approximately 7% to approximately 25%, which includes every ten of a percentage between 7% and 25%, for example 16.9%. In one embodiment, the relative difference between the raised area of the first relief design element 14 and the second element Embossed design 16 may be less than about 10%, or less than about 7%, or less than about 5%, or less than about 3%. The relief area of a relief element on an embossed absorbent paper product can be determined by considering the area of the relief roll elements that produced relief on the embossed absorbent paper product, the relief roll elements that produce a close approximation in the area of the embossed absorbent paper product. In one embodiment, the relief area of a relief element can be determined by using a visual image in which the relief elements are highlighted by hand or electronically, and the relief area is determined by mathematical calculations.

According to the understanding of the above description with respect to roll positions and balance, the number, spacing and location of the first and second relief design elements may vary for the visual impression desired by the manufacturer or vendor of the product. absorbent paper. However, for the rolled absorbent paper products 10 of the present invention, in one embodiment, the number, spacing and location of the second relief design element 16 may be sufficient to ensure that at least one second relief design element 16 at least intersects, partially, with a line of brittleness 24, as shown in Figure 2. In one embodiment, the number, spacing and location of the second relief design element 16 may be sufficient to ensure that at least two , or at least 4, or at least 6, or at least 8, or at least 10, or at least 12 seconds embossed design elements 16 at least partially intersect a line of frailty 24. As shown in FIG. Figure 2, for example, each second relief design element 16 at least intersects, partially, with a line of fragility 24. It is not necessary for each second relief design element 16 to at least partially intersect with line of fragility 24, but at except one can.

The advantage of producing a rolled absorbent paper product in which one or more second relief design elements 16 intersect in one or more line of embrittlement 24 is to maximize when the second relief design element 16 is a source identifier as a logo, brand name or registered trademark. When a person uses a paper towel, for example, and extends to tear a sheet, the user's eyes are attracted to the roll of paper towels and can specifically attract the line of fragility in which the break propagates. Consequently, in the action of the user's normal behavior when pulling a paper towel, the user is necessarily exposed to a visual representation of the logo, brand name or trademark of the manufacturer and / or seller. This activity which, of course, can be maintained for all rolled absorbent paper products that include toilet paper, helps to ensure that the identification of the manufacturer and / or vendor is reinforced since the user is reminded of the source of the rolled absorbent product.

The logo, brand name or trademark can be raised by providing the logo, brand name or trademark on the relief roller, such as the representative relief roller 38 shown in Figure 3. The relief roller 38 shown in Figure 3 it can be a steel roll manufactured by a means known in the art for rolls for steel embossing. The bonding roller (not shown) may be a rubber roller (or other soft surface) or a steel bonding roller as is known in the art. The representative relief roller 38 shown in Figure 3 produces an embossed pattern on the absorbent paper product 12 as shown in Figures 1 and 2. Accordingly, as can be understood, a first relief roller element 40 which includes two concentric diamonds to the first relief design element 14, and a second relief roller element 42 of the BOUNTY® brand name corresponds to the second relief design element 16. As with the pattern shown in Figure 2, the relief roller elements Further, such as the point (or point or mark) of relief roller elements 44 can be arranged in a spaced-apart configuration to form a roller pattern for wavy line relief 46. With respect to the determination of roll and area balance of percentage of relief elements at any given position 22, the roll elements for relief at point 44 can be taken into account.

As can be understood from the above description and with respect to Figures 2 and 3, in the present invention, the relief roller 38 can have a pattern of first roller elements for regularly spaced relief 40 where in certain positions 22 a second relief roller element 42 to provide a periodic relief of a logo, brand name, or trademark, while maintaining a relatively small percentage of relief area difference between the first relief roller elements and the second roller elements for relief (including, as necessary, other surrounding relief elements such as relief roller elements at point 44). As can be seen from Figure 3, the second relief roller element 42 can be displaced, i.e. replace, some of the relief pattern roller elements at point 44 which form a roller pattern for embossing in a waved line 46. number of roller elements for embossing at point 44 that can be displaced can be adjusted by depending on the size and relief area of the relief elements in line of the second pattern element of relief roller 42 to form a relatively low relief area difference between the first relief roller element 40 and a second relief roller element 42.

A representative pattern is repeated in the representative relief pattern shown in Figures 1-3 is shown in Figure 4. Figure 4 may represent a repeat pattern of figure, as well as represents the pattern of the first relief roll element 40 or, consequently, when applied to the paper product absorbent in a single operation for embossing, Figure 4 may represent a patterning of the relief design elements 14 in the finished absorbent paper product 12. In one embodiment, and to simplify, as described above, the method for how to calculate the relief element area can be achieved for a close working approximation by calculating the area of relief roller elements 38. For any position 22 on which a relief roller element is centered, an area can be determined inscribed 48 such as when defining a closed perimeter, such as a circle 50, centered at position 22. Of course, the inscribed area 48 need not be a circle, but may be of any sufficient shape to inscribe at least one relief element, such as a square, as shown in Figures 4A -4C, sufficient to inscribe a roll element for relief 40. Furthermore, as can be understood from the description in the present description, the inscribed area 48 can also inscribe, or partially inscribe, other relief elements as long as it is Apply a consistent inscribed area 48 to all positions 22 occupied by a relief roll element.

Once an inscribed area 48 is determined, the flat face area F (as shown in Figure 7, which is a representative cross-sectional description of all the relieves of the relief roller of the present invention) of the roller elements for embossing, such as the paper contacting outer surface of the in-line elements that form the first relief roller elements 40 (and portions thereof, as shown in Figure 4, in which the inscribed area 48 includes parts of the first four roller elements for external relief 40), as well as roller elements for relief 44. The area of the substantially flat faces of the various relief roller elements can be added to achieve a total relief area. The total area of the relief can be divided by the inscribed area 48 to arrive at a percentage of relief area for any relief element given around a position 22 in which the relief elements are centered.

As shown in Figures 4A-4C, the inscribed area 48 can be a square and the second relief design element can include linear relief letters (Figure 4A) or block relief letters (Figure 4C). The letters in relief in block, which are letters in which the full letter is in relief, can be used for the logo, brand name or trademark of the second relief design element, but, of course, they will have a raised area higher. In one embodiment, the percentage of the relief area for the first relief elements 16 (and, correspondingly, the first relief roller elements 40) can be substantially equal to the percentage of relief area for a second design element in relief 14 (and consequently, a second roller element for relief 42).

For the relief design elements shown by way of example in the present description, in Figures 1 and 2, as formed by a roll for relief as shown in Figure 3 (or similar to this), and for the areas of relief calculated by inscribing a square inscribed area 48 as shown in Figures 4-A-4C, the percentage of relief areas can be as follows (relief areas of all the relief elements inscribed, which include roller elements for relief at point 44 and portions of inscribed linear reliefs 56). The percentage of relief area for the second relief design element 16 (or, for a close operation approach, the second relief roll element 42) as shown in Figure 4A, may be about 15.6%. The percentage of relief area for the first relief design element 14 (or for a close working approach, the first roller element for relief 40) as shown in Figure 4B, may be approximately 16.9%. The percentage of relief area for the second relief design element 16 (or for an approach in close operation, the second relief roller element 42) as shown in Figure 4A, may be approximately 20.3%. In one embodiment, the difference between the relief area of a first relief roller element and a second relief roller element may be less than about 10%, or less than about 7%, or less than about 5% or less that approximately 3%. In the same way, the difference between the relief area of the reliefs in the finished absorbent paper product 12 can be determined by direct measurement or by close approximation of the relief roller elements responsible for making their first respective relief design elements. 13 or second design elements 16 or reliefs in little spaced point 20.

As shown in Figure 3, the first and second relief roller elements 40, 42 may comprise continuous or substantially continuous ridge elements 54 forming in-line reliefs 56 on the embossed absorbent paper product 12 (as shown in FIG. Figure 1). The reliefs in line present certain obstacles for the purposes of engraving reliefs on absorbent paper products. For example, due to web tensions during conversion operations, which include embossment, linear orientations oriented in the MD tend to cause wrinkles after embossing the reliefs and after the tension is released from the absorbent paper product. Wrinkles may be desired, in this case linear MD reliefs may be used; In any other way; however, certain design limits may be used in the present invention, to minimize the length of a linear relief element oriented on the MD. In one embodiment of the present invention, there are no linear reliefs that have a length greater than about 0.64 cm (one quarter of an inch), or greater than about 0.32 cm (one-eighth of an inch) oriented in the MD. In one embodiment of the present invention, for any given continuous relief (e.g., a diamond shape of the first relief roll element), less than 25%, or less than 10%, or less than 5% The line length is oriented in the MD. Stated differently and as illustrated in Figure 4, any given continuous ridge member 54 (or linear relief 56 on the absorbent paper product) may have a vector component 58 on the MD and a vector component 60 on the CD . In one embodiment, the vector component in the CD is sufficient to convert the linear element to create an angle A of at least about 10 degrees of an axis parallel to the CD.

Generally, as shown in Figure 4, it is believed that it is a good practice of relief to cause the full relief pattern of the roll to be repeated at a slight angle B with respect to a reference line 52 parallel to the axis of the roll for relief. . The angle B can be from about 1 degree to about 5 degrees and can be about 2 degrees, 2.5 degrees, 3 degrees, 3.5 degrees, or about 2.6 degrees.

Figure 5 shows a representative surface 58 of a relief roller 38 in a planar configuration. That is, Figure 5 shows the surface 58 of a relief roller 38 as it would look if it were "unrolled" and laid flat. The central line oriented towards the CD 60 can also be considered to represent a roller axis when the surface is curved on the roll for relief. As shown, a roll for relief may have a roll width RW, and a roll circumference RC. In one embodiment, the roll width RW may be approximately 279 cm (110 inches) and the circumference of the roll RC may be from about 91 cm to about 508 cm (about 36 inches to about 200 inches). The relief roller 38 may comprise a plurality of first relief roller elements 40 occupying positions 22 in a regular repeat pattern that is complete except for the replacement at certain positions 22 of second relief roller elements 42. As can be seen , by observing the reference lines 62 arranged in three representative sets of second relief roller elements 42, the second relief roller elements 42 can be arranged in positions 22 so that they are inclined at an angle C with respect to the axis 60, and can be arranged in a spiral on the circumference of the relief roller 38.

A second representative relief roller element 42 (which can produce a second relief design element 16 in an embossed absorbent paper product 12) is shown in greater detail in Figure 5A. As shown, in one embodiment, the second relief roll element 42 can be a word formed of linear relief letters 64, wherein each letter comprises an open area 66 within the linear relief. The linear relief letters 64 are shown in greater detail in Figures 6 and 8. Figure 6 shows a detail of the first two letters of the word BOUNTY, as shown in Figure 5A. As shown, each letter may have a linear relief perimeter 56 that forms a contoured shape of the given letter. The perimeter 56 of linear relief may be an embossed element which may have an average width WLE measured on the outer face contacting the paper F from about 0.051 cm to about 0.305 cm (approximately 0. 020 inches to about 0.120 inches), which include every 0.003 cm (0.001 inch) increase between, such as, for example, 0.13 cm (0.051 inches). The line width of the embossed perimeter relief element may vary, even in the letter joint, such as in the joint 68 where the linear relief element 56 forms a common perimeter element for the "B" and " Or "of the word BOUNTY.

As shown in Figure 7, which is a representative cross-sectional description of the cross section 7-7 of Figure 6, the linear reliefs 56 may have a height E of about 0.13 cm to about 0.432 cm (about 0.050 inches to about 0.170). inches), which include every 0.001 increment in the medium, such as, for example, 0.330 cm (0.130 inches). Linear reliefs 56 may have side walls that can be inclined at an included angle D of about 10 degrees to about 55 degrees, including each integral value of the angle in the middle, including, for example, 20 degrees. The upper surface contacting the paper F of the linear relief 56 can be substantially flat, and have a WLE width of about 0.051 cm to about 0.305 cm (about 0.020 inches to about 0.120 inches), which includes every 0.003 cm (0.001 inch) ) increase in medium, which includes, for example, 0.076 cm (0.030 inches).

Each letter 64 may comprise an open area 66 which for each letter may be from about 9% to about 23% of the area covered by the complete outer perimeter of the letter 64. For a given overall size measured from outer edge of the crest elements continuous 54 forming linear relief elements, the open area 66 may vary and depends on the width WLE of the linear reliefs 56, and, for certain letters, such as "B" and "O" shown in Figure 6, the size of interior letter relief elements 70. In letters such as "V" that do not have true "interior" portions for a 70 letter relief element, the area within the "V" can be considered a relief element of inner letter 70, as indicated by the dashed lines in Figure 8.

The advantages of the linear relief letters 64 of the second relief roller elements 42 of the present invention are many. First, a second raised design 16 made by the linear relief letters 64 of the element, the second relief roller element 42 provides visually discernible relief impressions in the absorbent paper product 12 due to the shading that can occur in narrow, relatively deep channels formed by the walls of the relief portion in the absorbent paper product 12, as it was shown in Figure 1. The linear reliefs form a perimeter of each letter, which in an incident light on the paper shows shadows and portions of light that help to improve the visual aesthetic qualities of the raised letters 64.

Second, a letter with linear reliefs provides an excellent impression of visually discernible relief without requiring an excessive percentage of relief area which could lead to an unbalanced relief roll 38. In a non-limiting example, for the second relief roller element 42 illustrated in Figure 4, if the letters of the word BOUNTY were solid, ie, filled, the percentage of relief area of the second roller element for embossing 42 would be approximately 20.3%, which is higher than the 16.9% relief area of the first relief roller elements 40. Like the letters in linear relief, the word BOUNTY as described in Figure 4 provides a second relief roller element 42 having a relief area of approximately 15.6%, which is about 8% difference with respect to the first relief roller element 40, which may be acceptable for the proper roll balance for relief 38.

In addition, a linear raised letter 64 provides the ability to hold more of the absorbent portions of an absorbent paper product capable of absorbing. A filled letter would densify more area, in fact the entire area of the letter could, effectively, cause the densified area to lose effective absorbing capacity, thereby reducing the overall absorbent capacity of the absorbent paper product.

Finally, a linear relief letter 64 may provide a larger word for embossing, while minimizing the percentage of relief area of the word, which may be the second relief design element 16. A larger word that is seen , probably, by the user at a point of purchase, or at the time of use, for example, when the user starts a sheet to use. As described above, a larger word (or logo or registered trademark) can be seen, more easily, by the user, when the user boots a sheet, especially if, as described in the present description, the word traverses a line of fragility, such as a perforation.
