Abstract
Disclosed is a core for core wound paper products, such as toilet tissue or paper towels. The core is provided with a plurality of axially oriented continuous score lines, perforations, or holes. The continuous score lines, perforations, or holes weaken the core, so that upon flattening, vertices are formed. When the core is rerounded, each score line, perforation, or hole forms a vertex, so that a predefined polygonally shaped cross section, more nearly approximating a circle, is formed.
Description
The present invention relates to a kind of fuse that is used for the goods on the fuse (hereinafter to be referred as core around paper products), be specifically related to a kind of will through flattening or compression its wasted space is reduced to minimum fuse, relate more specifically to a kind of have make the fuse of fuse fourth contact to the flattening of the device that more approaches its virgin state.
Core is well-known around paper products, such as toilet paper and paper handkerchief, in the industry, and is widely used consumption goods.Such goods comprise a fuse that is wound with multi-ply paper product on it.Fuse can be and also often be, the interim storage and the facility that are enclosed within convenient paper products on the axle take out paper products from paper roll when needed.Therefore axle is passed the center of fuse, requires fuse to open wide, and axle can be passed therethrough and can not run into excessive friction, and can not cause difficulty when taking paper products afterwards.
A kind of preferred fuse shape is one, and to have cross-sectional plane be circular cylinder, makes fuse together with can freely rotating round the axis of axle around thereon paper products, and paper products can easily be taken out from paper roll.An improvement to the paper roll on fuse is to press the sub wasted space that reduces in the fuse along a direction compression perpendicular to the fuse axis.Such structure makes core be convenient to storage, loading and unloading and transportation around paper products, and this is because such goods can store and transport more economically, and density is higher.
In the present technique field, once proposed multiple scheme and utilized the benefit of the core of compression around paper products.For example, the US Patent 4,909,388 of authorizing people's such as Watanabe US Patent 4,762,061 on August 9th, 1988 and authorizing Watanabe March 20 nineteen ninety discloses one of one of two parts of the green diameter that is compressed to goods to five parts paper products volume.The fuse of these goods has slight elasticity, and the recovery of shape that enables to flatten from compressed one-tenth is to original cylindrical shape.According to these patents, the paper roll that total is has wished to flatten can easily be returned to its original shape.
The US Patent 1,005,787 of authorizing Sibley in October, 1911 discloses a kind of around a toilet paper bag by the flattening on hollow fuse flexibility and that make with the ground paper of corrugation in the axial direction.The fuse of band corrugation is hung toilet paper, causes producing vibration when paper roll is got paper.The European patent 709,363 of authorizing Samson on May 19th, 1954 discloses a kind of paper web or flexible sheet material on a fuse, and this fuse is that diameter flattens and says that becoming is very fast its tubular form of recovery after opening bag.This fuse is made of the kraft paper strip of reeling spirally and has a flexibility.Its flexibility says that becoming is fuse can be flattened and can not ftracture and can recover its drum after flattening.
The US Patent 4,886,167 of authorizing Dearwater on December 12nd, 1989 discloses a kind of toilet paper with unidirectional compression of the flattening fuse that has seldom even do not have wasted space between the radially relative face of the fuse cross-sectional plane that flattens.The patent of Dearwater is attached in the application by reference, purpose be to illustrate particularly preferred closely, the toilet roll or the paper towel roll of compression.
More than all there is such shortcoming in the patent of Jie Shaoing, that is, when fourth contact, radially relative fold usually occurs and make it can not be returned to desired drum on whole fuse.It is bad that these fold usually cause fuse to be adorned on axle, gives the user when being enclosed within fuse on the axle, using on the axle or making troubles when axle is taken off at every turn at every turn at every turn.In addition, the round cross-sectional plane of such fuse will hinder paper products easily to take out from paper roll, make the user feel very inconvenient when wanting to take off a slice or more paper products at every turn.Having not, the fuse of circle cross-section generally all can bring bigger noise in use.
A kind of scheme that overcomes the problem that is associated with the fuse flattening is the flattening of avoiding such, and is such as disclosed scheme in the US Patent 2,659,543 of authorizing Guyer in November 17 nineteen fifty-three, and this patent proposes a kind of method of keeping original fuse shape.This patent is introduced a kind of fuse of belt product, and such fuse has at least one along ditch or the groove of fuse outer shaft to stretching, extension, or has many ditch or the grooves that the circumferential well-distributed in edge is such.When material was tightly on fuse, the slight shrinkage depression of groove relaxed because belt caused compression banding stress on the fuse tightly.But this scheme exists and is keeping the circular cross section of fuse and lose the shortcoming of flattening the above-mentioned advantage that fuse brings.
Therefore, needed be a kind of can equally flatten with prior art but can be more easily after being applied to compressing stress on the paper products and removing and the fuse of fourth contact more accurately.
Therefore, the object of the present invention is to provide a kind of have be used to flatten with to user's mode fourth contact fuse and can be accurately be returned to more fuse more easily near the device of its original form with making fuse repeatedly.
The present invention comprises a kind of fuse that is wound with paper products with the flattening that constitutes paper roll on it.The fuse of this flattening has two opposite end of interior week, periphery and qualification longitudinal axis.The fuse that flattens can return to when fourth contact near circular cross-sectional plane.Fuse also comprises at least one and is used to weaken the anti-device that unloads the drag of the compressive force that applies of fuse, in reducer is arranged at least one of in the periphery on, the whole thickness that perhaps can penetrate fuse runs through the interior periphery of fuse.
In one embodiment, reducer is many continuous score lines that stretch vertically.In a second embodiment, reducer is a plurality of incisor paths that stretch vertically.In the 3rd embodiment, reducer is a plurality of holes of orientation vertically.Groove, incisor path or hole can not penetrate, so fuse has only a side face influenced by reducer, and perhaps the reducer whole thickness that can penetrate fuse runs through the interior periphery of fuse.
Although claims of the application specifically and have clearly proposed the scope of protection of present invention, believe by following description taken together with the accompanying drawings better understanding to be arranged to the present invention.In the accompanying drawings, part roughly the same is with identical label.

" fuse " described in the present specification refer to one be wound with that another is helically wound on it, in order to hollow cylindrical member of the product that uses later on and take out.Described herein " paper products " refer to a kind of on fuse 20, generally be the product that once takes out one or more cellulosic material of taking in this wise in batches and after use, abandoning.Paper products 24 are not return on the fuse after taking out use from fuse 20.Described herein " paper roll " refers to one " fuse " and fabricate block around thereon " paper products ".Paper roll 28 can also have a foreskin 32 it is held in shape shown in Figure 1.
When toilet paper was wrapped on the fuse 20, the diameter of toilet roll 28 generally was that the length between its two ends generally is about 11.4 centimetres (4.5 inches) from about 10.2 centimetres to about 12.7 centimetres (promptly 4.00 to 5.00 inches).If fuse 20 of the present invention is used for towel products, by embodiment described herein, the diameter of paper towel roll 28 generally is that its length generally is about 27.9 centimetres (11.0 inches) from about 10.2 centimetres to about 15.2 centimetres (4.00 to 6.00 inches).
" compressive force that applies along diametric(al) " as herein described refers to the compressive force in opposite directions on any diameter in any cross section that is applied to fuse 20.Certainly, be appreciated that compressive force may apply along a string in cross section and do not overlap with a diameter.But the principle that relates in such occasion follows the compressive force that applies along diametric(al) the same basically, thereby is here no longer distinguished or heavily cover.
When applying compressive force, fuse 20 will collapse to collapsed state shown in Figure 1.The cross-sectional plane of the fuse 20 of flattening shown in Figure 1 has a major axis a-a and a vertical with it minor axis i-i.The major axis a-a of cross-sectional plane follows the longitudinal axis of fuse 20 to become laterally with minor axis i-i and is vertical with it.After flattening, major axis a-a aims at the longest dimension of the cross-sectional plane of paper products 24, and minor axis i-i is the perpendicular bisector of major axis.
Through finding, at least need one at the device 36 that the drag that is used for weakening the compressive force that fuse 20 resists to apply upwards is set in week, best-but not necessarily necessary-uniformly-spaced be provided with the adjacent device 36 that plays same purpose, make the cross-sectional plane of fuse 20 when fourth contact, more approach a circle, rather than a fitfull polygon.
The major axis a-a of the fuse 20 that flattens and location, the azimuth of minor axis i-i can be pre-determined at layout that makes progress in week and interval by the device 36 of the drag that is used to weaken the compressive force that fuse 20 antagonism apply.If fuse 20 is provided with two devices 36 of drag that are used to weaken the compressive force that fuse 20 resists to apply that are oppositely arranged on diametric(al), if and the diameter that compressive force applies thereon becomes 90 ° approximately with respect to these two reducers 36, this fuse 20 will roughly be crushed in the position of these two reducers 36.
But fuse 20 can not be returned to when fourth contact and approach original drum, and this is almost to be the shape of bilateral protrusion because two peak dots are held in the cross-sectional plane of fuse 20.Provide more peak dot just need more reducer 36 upwards be set week, like this, fuse 20 will be the polygon cross-sectional plane when fourth contact, and its limit number is equivalent to the peak dot number, and each peak dot is equivalent to specific being used to and weakens the device 36 that fuse 20 resists the drag of the compressive force that applies.
As mentioned above, because fuse 20 is bilateral protrusion shape behind fourth contact, fuse 20 is not suitable for being provided with the individual reducer 36 of even numbers, a pair of or how two all improper.If 4 reducers 36 are set, fuse 20 is the cross-sectional plane of a general square shape and has a hollow hexahedral shape behind fourth contact.Too much rocking and excessive noise can appear in this fuse 20 when being enclosed within on the axle behind fourth contact, therefore generally do not recommend to adopt.
One has 6 reducers that are spacedly distributed 36 and works respond well on circumferentially.Fuse 20 whenever brings out existing reducer 36 at its end face major axis a-a when flattening, the fuse 20 that flattens has two reducers 36 on the face of each flattening, these two reducers 36 are minor axis i-i and arranged side by side with two reducers 36 on the face of relative flattening athwart.Be a hexagonal cross-section behind this fuse 20 fourth contacts and rock with noise all smaller in use.
Fuse with 8,10 or 12 reducers 36 of uniformly-spaced arranging is undesirable, because such fuse has an aptitude that constitutes a quadrangular cross section when fourth contact.This structure also needs two sections fourth contacts, and is more inconvenient to the user.
As shown in Figure 2, a kind of device 36 particularly preferred, that be used to weaken the drag of the compressive force that fuse 20 resists to apply is the groove of a continuous axial stretching, extension.Groove preferably is parallel to the axis of fuse 20, but if desired also can spirality round fuse 20.If less than 45 °, this reducer 36 just is counted as " stretching vertically " to the line that stretches along reducer 36 with the formed angle of longitudinal axis of fuse 20.
Groove can be located on going up in interior week of fuse 20 or the periphery.Clearly, if be provided with many grooves, these grooves can divide on the interior periphery that is located at fuse 20.
" groove " as herein described comprises indentation line, and preferably includes the line that removes material formation from fuse 20.Groove can be made with mint-mark chi or rotating die head, groove preferably be pressed into fuse 20 thickness about 25% to 100%.Groove is preferably in and stretches between the two ends of fuse 20 and be stretched on the two ends.
If desired, the device 36 of the drag of the compressive force of resisting to apply such as groove such being used to weakening fuse 20 can be continuous, discontinuous or interrupted, and can be corresponding to a plurality of discontinuous holes or incisor path.These discontinuous holes or incisor path can-but nonessential-be stretched over every end of fuse 20, and can begin to stagger in the axial direction placement from the termination of fuse 20.
For example, Fig. 3 to Figure 10 illustrates 8 non-limiting instance successively, and the various devices 36 that are used to weaken the drag of the compressive force that fuse 20 resists to apply are shown.Table 1 is listed a kind of sample of each example, so that come easily the effect of fuse 20 when the fourth contact compared by parameter listed in the table 1.
A kind of sample of each row representative in the table 1, they are that the toilet paper of the Charmin plate that can buy on that Prolongert Gamble Co., Ltd according to the Cincinnati, Ohio makes and sells, the market prepares.Fuse 20 is taken out from the paper roll 28 of paper products 24, on fuse, make the described device 36 that is used to weaken the drag of the compressive force that fuse 20 resists to apply, again these fuses 20 are turned back to the center of paper products 24 to form complete paper roll 28.On diametric(al), compress along its minor axis i-i with the power of one about 36 kilograms (80 pounds) paper roll 28 then paper products 24.
The paper products 24 that will become web-like subsequently carry out about four week of timeliness under the temperature of about 50% relative humidity and 72.It is necessary that the timeliness cycle of one minimum fortnight is considered to allow any memory of fuse 20 or elasticity be developed, and therefore is similar to the condition of depositing and transporting and obtains the sample accurate data during fourth contact afterwards.Be less than that timeliness cycle of fortnight is considered to not meet the requirements, because obtained result is not similar to actual conditions, in actual conditions, paper products pass through manufacturing, storage, are transported to the point of sale, sell, take in the customer family, also install on the axle at last and use.
The above-mentioned material of each fuse 20 usefulness is made, and its length is about 11.43 centimetres (4.5 inches).Sample shown in Fig. 3 to 10 is provided with 6 devices 36 that weaken the drag of the compressive force that fuse 20 resists to apply by being used to of uniformly-spaced being provided with, a perforation otch that is used to open fuse 20,5 drags that are used to weaken the compressive force that fuse 20 resists to apply, this will be described below.
The figure number of the planar view of the device 36 of describing the described drag that weakens the compressive force that fuse 20 resists to apply is shown in the 1st tabulation of table 1.The 2nd row of table 1 are described the feature of 5 reducers 36.But the fuse 20 of these samples cuts like that and opens to be provided with on fuse 20 shown in must the planar view of map interlinking 3 to 10 and adds up to 6 described reducer 36, to weaken the drag of the compressive force that fuse 20 resists to apply selectively.
When 5 described reducers 36 crack when using with a continuous perforation, the cracking with adhesive tape involution again of this perforation then with fuse 20 compressions, make major axis a-a when flattening with cracking of clinging with adhesive tape with a described reducer 36 intersects.In practice, aforementioned perforation is cracked and can be substituted with the same reducer of other 5 described reducers 36 with one, so all 6 devices that are used to weaken the drag of the compressive force that fuse 20 resists to apply have been individual identical.
The percentum of the axial straight-line dimension of the fuse 20 that the percentum that perforation that table 1 the 3rd row are listed or incisor path account for axial dimension is had influence on by reducer 36.Total straight-line dimension of the reducer 36 of each fuse 20 is 68.6 centimetres (6 * 4.5=27 inches).In the 4th row of table 1, list vertically the distribution situation of each reducer 36 on fuse 20, for example: from the end to the end and stretch total length by fuse 20, be located in the middle of and be not stretched over the end or be located at that two ends begin from the end and discontinuous in the centre.
The peak dot of listing each reducer 36 at the 5th of table 1 forms effect, is fuse 20 fourth contacts are now being judged to determine according to main during to its original cylindrical shape state, be divided into basic, normal, high Three Estate.If fuse can't see tangible peak dot behind fourth contact, the peak dot of this sample forms effect and just is judged as low.Change if tangible curvature direction occurs in one or more peak dots position, the peak dot of this sample forms effect and is judged as medium.If form knuckle at reducer 36 place's peak dots, the peak dot of this sample forms effect and is judged as high.
Fuse sample shown in Figure 3 is provided with 5 holes, and its diameter is about 6.4 millimeters (0.25 inches).Each hole is with stagger the in the axial direction distance of length of one of about five parts fuse 20 of its circumferential adjacent holes.
Fuse sample shown in Figure 4 is provided with the hole of 10 circumferential spaced apart settings in edge, and its diameter is about 6.4 millimeters (0.25 inches), and every end is established 5.Establish at grade in per 5 holes, and be provided with at 2.54 centimetres towards the Rio from the end of fuse 20 position.5 holes on an end of fuse 20 follow corresponding 5 holes on the other end of fuse 20 to aim in the axial direction.
Fuse sample shown in Figure 5 is made incisor path from every end of fuse 20 towards the center, and incisor path is about 2.54 centimetres (1 inches), is distinguished with not cutting of long 1 millimeter (0.04 inch) by the cutting area of 1 millimeter of the length that is arranged alternately (0.04 inch) to constitute.
The incisor path of fuse sample shown in Figure 6 is made of the cutting area 40 of 1 millimeter of the length that is arranged alternately (0.04 inch) and the district 44 of not cutting of long 1 millimeter (0.04 inch).Cutting area 40 is on the interior week of fuse 20, and cutting-in is half of thickness of fuse 20.Effective percentum ground of the cutting area of the sample of Fig. 6 has reduced by half, and this is because otch only influences half of gross thickness of fuse 20.
The incisor path of fuse sample shown in Figure 7 is made of the cutting area 40 of 2 millimeters of the length that is arranged alternately (0.08 inch) and the district 44 of not cutting of long 6 millimeters (0.24 inches).Cutting area 40 and the total length of not cutting district's 44 stretching, extensions passing through fuse 20.
Fuse sample shown in Figure 8 is provided with two cutting areas 40, and the length of each cutting area is about 2.54 centimetres (1 inches), about 1.27 centimetres away from end of fuse 20 be at one end (0.5 inch).
The incisor path of fuse sample shown in Figure 9 is made of the cutting area 40 of 9.6 millimeters of the length that is arranged alternately (0.38 inch) and the district 44 of not cutting of long 9.6 millimeters (0.38 inches).Incisor path is stretched over the other end from an end of fuse 20.
The incisor path of fuse sample shown in Figure 10 is made of the cutting area 40 of 1 millimeter of the length that is arranged alternately (0.04 inch) and the district 44 of not cutting of long 1 millimeter (0.04 inch).Incisor path is stretched over the other end from an end of fuse 20.
Fuse sample shown in Figure 11 is provided with the cutting area 40 and not the cutting of long 1 millimeter (0.04 inch) of the length 3 millimeters (0.12 inches) that is arranged alternately and distinguishes 44.Incisor path is stretched over the other end from an end of fuse 20.
Can find out that from table 1 in general, when the reducer 36 of fuse sample accounts for about 20% when following of fuse axial dimension, its peak dot forms effect and is judged as low.When reducer 36 accounted for the fuse axial dimension and reaches 20% to 45%, with respect to other sample, its peak dot formed effect and is judged as medium.When reducer 36 accounted for the fuse axial dimension and surpasses 50%, its peak dot formed effect and just is judged as high.All samples are placed on the axle then for using.But all samples all proves than not possessing the superior with reference to sample of reducer 36 aspect uninterrupted at noise and level and smooth the use.
