Abstract
The invention relates to a roll of paper tissue separated into a plurality of tissue segments by means of lines of weakness, each tissue segment having a width between opposite side edges, and a length between lines of weakness, each line of weakness being essentially straight, and extending orthogonally relative to the side edges of the paper tissue wherein the basis weight of the paper tissue is at least 40 g/m<2> and wherein the ratio of the length of a tissue segment to the width of the tissue segment is at least 1.7:1.
Description
The present invention relates to a kind of mode that weakens line with intensity and be separated into the thin paper volume of a plurality of tissue web sheets and the purposes, the particularly use on toilet paper of this volume.
Such as the thin paper of paper handkerchief, face tissue and toilet paper or paper is staple in the daily life.A large amount of demands and the continuous demand that has produced the improved form of this series products of using to this consumer goods.
Three important physical characteristic that it is believed that this series products for a long time are its flexibilities; Its absorbability; With its intensity.The effort of research and development has related to each characteristic has been improved, and other characteristic is not had a negative impact and improve two or three characteristics simultaneously.
Flexibility is that the consumer grips specific product at him, the product that rubs on his/her skin, the perhaps sense of touch of being felt when his/her rubs the wrinkle product on hand.This sense of touch is the combination of several physical characteristics.Those skilled in the art it has been generally acknowledged that: a prior physical characteristic that relates to flexibility is the stiffness of the thin paper that is used to manufacture a product.Stiffness thinks directly to depend on the dry tensile strength of paper web usually again.
Intensity be the physical integrity kept of product and under user mode opposing tear, break and the ability of cracking.
Absorbability be the product absorption liquid scale of construction ability measure especially moisture solution or suspension.Be commonly referred to be the total amount of the fluid that the given quality of thin paper absorbs by the total absorptivity that the consumer felt when saturated, and both comprehensive of the speed of the thin paper absorption fluids of this quality.
In this three specific character, pliability and intensity are two most important characteristics to toilet paper.Toilet paper the most normally offers the consumer with the form of volume.Usually for the ease of tearing the thin paper of the certain-length that will use, volume is separated into a plurality of thin paper bursts in the mode that intensity weakens line.Each thin paper burst has the width between the opposite side edge, and intensity weakens the length between the line, and it is straight basically that each intensity weakens line, and vertically extends with respect to the lateral edges of thin paper.
The US-A-4687153 that authorizes on August 18th, 1987 has announced and has been suitable for making peelable multi-ply tissue winding apparatus, made by thin paper is bored a hole especially.The possibility of change yardage (that is the length between the perforation) and paper number (that is the number of paper in the volume) has also been proposed.Yet this patent does not propose how optimization of yardage.
Because intensity weakens the characteristic of line, when using two or more thin paper burst, intensity weakens the overall strength that line has weakened thin paper.
The objective of the invention is to continue working strength and weaken line, and improve the overall strength of the thin paper of given length simultaneously so that tear the thin paper of given length.
Another object of the present invention provides a kind of consumer and can not contain the clear area that intensity weakens line owing to it provides with the folding tissue paper product of mode nature or custom, so use the possibility that lost efficacy less.
Summary of the invention
To have quantitatively be 40g/m to this purpose at least by providing
2The thin paper burst reach, wherein the length of thin paper burst is 1.7: 1 to the ratio of the width of thin paper burst at least, preferably is 1.9: 1 at least, more preferably is 2.5: 1 at least.According to the present invention, thin paper volume can be used to disperse the thin paper burst, particularly is used for disperseing toilet paper.
Detailed description of the invention
Before using, a lot of consumers folding thin paper, especially toilet paper.The custom of the majority among these consumers is to fold thin paper once, gives the thin paper bilayer thickness, though some consumers are folding more than once.The result is the thickness that a thin paper has two or more, and having is the clear area on plane basically.Perforation in any part of clear area forms low-intensity and weakens part, and has increased the possibility of the inefficacy in the use.The meaning that lost efficacy is that thin paper is torn, and fracture or spalling cause the cleaning effect that influences and under the situation of using toilet paper, make the consumer be in the offending filth.
Have been found that at present many consumers fold toilet paper, thereby make its length be substantially equal to distance from the finger tip of middle finger to the base portion of thumb (that is), perhaps be a bit larger tham this length just on the top of wrist.Usually, for the adult, this length is to 200mm from 160.In addition, the normal width of toilet paper approximately be 100mm to 120mm (its approximately with when the width of finger grip finger hand side by side from the thumb to the minimum together the time consistent).
The common custom of in the consumer another is that the clear area with thin paper is used for first clean operation, folding once more subsequently thin paper, and first clear area of making dirty folds into the inside, and thin paper is used further to second clean operation.Even second clear area that can repeat to make dirty folds into the inside, and thin paper is used further to the 3rd clean operation.
The present invention makes with these customs one or whole a large amount of consumers tear a plurality of thin paper bursts from volume, and folding with the method, thereby occurs not having the clear area of boring a hole fully.The risk that this means the product failure in the use has significantly reduced.In addition, for use first clear area and the consumer who folds and re-use thin paper more at least more than once, the advantage that always has the clear area of not having perforation is more important.In the process of the second time and clean operation subsequently, it is very little by the possibility of the leakage of thin paper that these consumers stand foul.
In particularly preferred embodiment of the present invention, it is sufficiently long that each thin paper burst tears a burst for the consumer, and once is a burst.Compare with the situation of the standard of use thin paper, these consumers can be benefited economically, for example each clean operation uses the long independent a slice of 190mm, and in the situation of the standard of use thin paper, same consumer habitually needs two standard thin papers long as 140mm, that is the long thin paper of 280mm altogether.
In another program, but among the particularly preferred embodiment of the present invention, the consumer can tear two thin paper bursts from volume, and can be at the perforation of the junction of these two bursts adminicle as folding burst.
According to a highly advantageous elaboration of the invention, the thin paper of individual layer or multilayer should have 40g/m at least
2Quantitatively, even be more preferably 50g/m at least
2, so that enough tissue materials are provided when only cleaning with one or two thin paper bursts.
Length is thin paper measured lengths on the direction consistent with the direction of the circumference of rolling up around thin paper in this meaning; Width, this meaning be thin paper volume laterally from a side to opposite side flat shape in the measured width of spool.Following situation is particularly preferred: the direction around thin paper volume (being length) is the machine direction of thin paper, and the direction of horizontal (width) of volume is the cross-machine direction of thin paper.
Intensity weakens line, is that thin paper has tearing configuration in this meaning, and wherein tearing configuration makes the consumer weaken line than other line is easy to tear along some along intensity.It is perforation line that highly preferred intensity weakens line.Perforation line is the otch of a plurality of intervals, prolongation, axially alignment mutually, and each otch is all separated with next otch by a thin paper that extends between adjacent otch.
Disperseing, is that product of the present invention can be removed from the thin paper volume in this meaning, and required length can weaken line and tears along the intensity of the perforation in the thin paper.Product of the present invention can and be used as the absorbent tissue of cleaning rigid surface and wipe paper as various cleaning thin papers that comprise face tissue and wiping paper.Preferable use of the present invention is the use at the thin paper volume that is used for disperseing toilet paper.
Thin paper of the present invention can be used the known commonsense method manufacturing of those of ordinary skill in the art, such as using as the slurries dehydration method of making paper web to being fit to.This process can be carried out in batch, but commercially carries out on continuous paper machine usually.Highly preferred thin paper can be by the US-A-3301746 that publishes on January 31st, 1967, the perhaps described method manufacturing of EP-A-0140404 of publishing on May 8th, 1985.Paper according to the EP-A-0140404 manufacturing is made up of first district and second district, first district has the monoplane of macroscopic view, add flower, have highdensity contiguous network and with respect to second district low quantitatively, second district by height quantitative and a plurality of discontinuous have with respect to the low-density cima in first district form.The preferred averag density of first network area is that the averag density of every cubic metre 0.4 to 0.8 gram and the cima in second district is every cubic metre 0.04 to 0.15 and restrains.Make the process of paper web or the optional step of process subsequently and comprise preshrunk, or wrinkling; Embossing and printing.
