Description
Technical field
The present invention relates to a kind of dispensing package that is used for wet wipe, dispensing package comprises container and the heap of wet wipe therein layer, and it can carry out improved spring branch to individual cleaning piece and get from wet wipe heap layer.
Background technology
Normally pre-humidification, the disposable face tissue of wet wipe can be used in family and the industrial various application occasions and finishes multiple function.Wet wipe is generally used for wiping life surface and inanimate surfaces, and a large amount of benefits can be provided, such as the benefit of cleaning, cleaning, sterilization and skin nursing.
A special applications is to use wet wipe to come cleaning person's body portion, particularly when can not utilizing daily water, for example at whilst on tour.Cleaning piece also is generally used for human cleaning and wiping is cleaned and face and hand cleaning as anus, perineum and external genital usually, as the direct type hygiene wipes of women's wet wipe.Wet wipe can also be used for applying material to health, comprises makeup removing and makes up, applies skin conditioner and medicament.The application of another kind of cleaning piece is in the diaper change process, and part is by the adult who uses diaper and incontinence apparatus to cause and the processing of baby's dermatitis.Except wet wipe also is used for wiping and other surface of cleaning, also be used for applying composite, for example kitchen and bathroom surfaces, glasses, footwear and the industrial surface that needs cleaning, for example machinery or car surface to the surface.Wet wipe also comprises the articles for use that are used for the pet cleaning or scrub.
Wet wipe is generally a kind of structure of syntheticfibres and natural fiber combination, and such as polyolein fiber, viscose and cotton fiber, it uses Aquo-composition wetting usually, and aqueous ingredients is contained in other inhibiter, anti fouling composition, oil and the smell.Cleaning piece is packaged in the container with convenient transportation and storage.
There is the container of two kinds of fundamental types to be used for these wet wipes, that is, and many cleaning piece containers and individual cleaning piece packing.In many cleaning piece containers of representative type, adopt the container of the waterproof branch of flexibility or rigidity, thereby cleaning piece is folding and be deposited in wherein that individual cleaning piece comes out and once taken away one by the customer.These containers are the tubbiness configuration or are flexible brick pack that the two generally is reclosable after opening.
At present the problem of wet wipe goods is: to get individual cleaning piece not too convenient for branch from wet wipe heap layer and container.This problem is such as embrace especially severe under baby's the situation when customer's hand in the diaper change process.Under this condition, customer Geng Yi requires only to use a hand to pick up from the cleaning piece heap layer of container and expansion and separates a cleaning piece, and the cleaning piece container does not raise from the surface at its place in removing the process of action.Yet present goods are difficult to satisfy this requirement.
Get a plurality of reasons of the unsatisfied the question resolves itself into of individual wet wipe to from cleaning piece heap layer and container, dividing.At first, wet wipe is generally folded up and a cleaning piece is placed on another cleaning piece top, and is perhaps interlaced and a cleaning piece is placed on another top and forms a pile with adjacent cleaning piece.Yet the definite position of the guide edge of going up cleaning piece most (leading edge) of cleaning piece heap layer is difficult for determining, is non-visible also non-self-evident at present.This be since the substrate of cleaning piece generally be homogeneous and therefore the guide edge of cleaning piece particularly when folding cleaning piece, can not separate with the cleaning piece basal area of its stop.In addition, the guide edge of cleaning piece part also has its stop suprabasil trend of below cleaning piece thereon that adheres to.Therefore, by finger being moved or towing strides across the cleaning piece surface and determines that the sense of touch at edge can not determine boundary position immediately.
Next, in case guide edge is located, difficult for consumers is to catch enough substrates and maintenance that it is gripped, so that pile individual cleaning piece of separation the layer from the cleaning piece of its stop.The customer can only catch the fraction of guide edge usually, thereby can not be to its tightly clamping and therefore cleaning piece slippage from customer's finger easily.
Getting these relevant problems with the wet wipe branch has been recognized in the art.For example US Patent 5540332 has been discussed the getting property of branch of wet wipe and the method for producing these cleaning pieces.Improved getting property of branch provides the non-linear pattern of repetition by at least a portion for one of end edge of cleaning piece, obtains such as the sinusoidal waveform configuration.Yet the problem that individual wet wipe branch is got is not by using non-linear guide edge to solve or overcoming.
Get the solution of another proposition of problem for branch and describe in US4778048, it discloses a kind of like this goods, be used for improve using, divide get and etc. liquid dispersion, by constituting at container inward flange bevelled wet wipe heap layer.In a preferred embodiment, the Gurley stiffness at every cleaning piece edge is greater than the stiffness of cleaning piece main body.Yet being provided with of this stiffening edge itself is the undesirable characteristic of wet wipe.What wet wipe, particularly those plans were used in the skin sensitivity district needs to a certain degree flexibility such as baby wipes.Therefore the cleaning piece edge of stiffeningization is not admitted by patient self, and cleaning piece has the substrate surface that is suitable for using of minimizing.It needs in addition to nurse and reduces or avoid this marginal portion to contact, because may cause stimulation with skin.And the stiffness at edge still can not solve the problem that individual cleaning piece branch is got.In addition, the setting of the nonlinear edge on the non-woven substrate of the current production technology of this use is also caused the wearing and tearing of extremely unfavorable basal edge.
For divide another crucial effective factor of getting individual wet wipe from wet wipe heap layer is the trend that the wet wipe substrate adheres to self.This situation ascribe to especially produce and storage process in the actual weight of compression, cleaning piece heap layer self of cleaning piece heap layer and substrate between the existence of detergent composition of gravitation and cleaning piece.The result is, when cleaning piece is folded to form the heap layer, substrate is easy to adhere to from one's body and in the substrate of adjacent cleaning piece.Thereby, in case the customer when cleaning piece heap layer lifts cleaning piece or pulling cleaning piece and takes away mouthful by branch, cleaning piece tends to keep its folding configuration.And cleaning piece generally is retained to small part and adheres to this cleaning piece and stop on the superincumbent adjacent cleaning piece.Therefore, except the process of the action of removing cleaning piece from cleaning piece heap layer, adjacent cleaning piece also separates the heap layer to small part from cleaning piece.The result is that the customer not only need launch cleaning piece before the required purposes of cleaning piece, and cleaning piece separated with adjacent cleaning piece in cleaning piece heap layer and this cleaning piece foldback is returned in the cleaning piece heap layer in the container.This is for obviously inconvenient especially the customer who uses baby wipes in the diaper change process.
Recognized the problem of cleaning piece substrate adhesion in the prior art.The trial that addresses this problem is present in usually in being provided with of the specific interlace configuration of cleaning piece, and for example describes in JP08089439.
Yet the staggered configuration of many propositions has the problem that is associated with it.Particularly, as staggered result, when the substrate overlapping degree between the adjacent cleaning piece is big, the problem worse of then substrate viscosity, thereby cleaning piece always actv. discharge in pairs.On the other hand, if the overlapping between the adjacent cleaning piece minimizes, thereby the branch that has guaranteed individual cleaning piece get, do not have the certifiable separation and exist guide edge to determine the problem that occurs once more from cleaning piece heap layer of adjacent cleaning piece.
Another problem that current wet wipe piles up be the cleaning piece branch get finish after a large amount of substrates of adjacent cleaning piece still expose by opening, particularly for a large amount of folding configurations that overlap of substrate between the adjacent cleaning piece.As a result, cleaning piece becomes dry, is unsuitable for using and must abandoning.EP747313 has proposed to address this problem has a kind ofly installed and discloses a large amount of folding paper, such as the wetability thin paper, is used for handling continuously by vessel port.Under this mode, be 1/4th of adjacent cleaning piece length to the maximum and take away by branch and mouthful to expose.Yet this thin paper products can not be used for all wet wipe application scenarios, such as baby wipes, because the wetability thin paper is unsatisfactory aspect flexibility and intensity.Particularly, this wetability thin paper in use is easy to tear, and is therefore uncomfortable as wet wipe.
Another kind of scheme is, the branch extracting container (so-called spring branch is got device) that people have also proposed to have particular design improves branch and gets.It is the container with opening last slice (panel) that these branches are got device.Spring divides gets device and works according to the principle that provides less branch to take away mouthful, the size manufacturing of opening and be configured to layer combine with the cleaning piece heap with special marked fold configuration, thereby the remaining among branch gets than top of adjacent cleaning piece.These containers are designed to removing from container by aperture in the course of action of going up cleaning piece most thus, in a single day adjacent cleaning piece is raised from cleaning piece heap layer, removes thereby go up cleaning piece most, and it partly stretches out by opening.Going up most cleaning piece with this method location is convenient to be caught by the customer.The spring branch of these types is got device and is allowed cleaning piece to be arranged on the continuous roller of tape punching, perhaps as folding separately cleaning piece, described in US5560514.
Regrettably, provide and have general minimum branch and get the branch in hole to get device be unfavorable for the customer.Particularly these openings hinder customers can see and check that the inclusion of container and estimation remain in cleaning piece quantity wherein.Except if spring was lost efficacy and adjacent sub is got cleaning piece does not lift from cleaning piece heap layer, to take away mouthful size little owing to divide, and the customer does not allow to change places and takes away mouth by branch and be input into cleaning piece and need dismounting to divide and get device.Same problem is got the device accidental shifting out than needs the customer from branch and is manyed a lot of cleaning piece and also can running into when making great efforts these cleaning pieces are put back into branch and get in the device.
Summary of the invention
Therefore an object of the present invention is to provide the wet wipe dispensing package, it is convenient to individual cleaning piece and separates from cleaning piece heap layer and container, prepares against use thereby launch cleaning piece under no any foregoing problems.
Therefore the present invention relates to cleaning person's body region and other surperficial wet wipe, as baby wipes.Particularly, the present invention relates to wet wipe spring and divide the system of getting, reduce and divide and get and separate individual cleaning piece to be convenient to the wet wipe heap layer in minute extracting container cleaning piece piled layer height.Divide extracting container to comprise container body, described container body comprises lower part and top, and it is that the branch of 14 sq cm to 65 sq cms is got the hole that top is divided into sectional area.The average separating force that cleaning piece has between these two cleaning pieces being determined by experimental technique is 75 gram/sq cm to 250 gram/cm3s.

According to the present invention, wet wipe comprises the substrate that applies or be impregnated with fluid composition.This substrate can be weaven goods or non-woven fleece, foam, sponge, flocculus, coccoid (ball), grand piece (puff) or film, most preferably non-woven fleece and can being made by natural or syntheticfibres or its compound.Preferably, fiber composition is the mixing of hydrophilic fiber material and hydrophobic fiber material, hydrophilic fiber material such as viscose glue, cotton or flax, hydrophobic fiber material such as polyethylene terephthalate (PET) or polypropylene (PP), blending ratio is 20%-80% for hydrophilic material by weight, and hydrophobic material is 80%-20%.Two kinds of particularly preferred composites are 50% viscose glue/50%PP and 50% viscose glue/50%PET.Substrate preferably quantitatively is at least 20 gram/sq ms and preferably less than 150 gram/sq ms, most preferably quantitatively scope is 20 gram/sq m to 70 gram/sq ms, more preferably is 50 gram/sq m to 65 gram/sq ms.This substrate can be any thickness.Usually, when substrate was made by the water law deinterleaving method, average substrate thickness was less than 0.8 millimeter.More preferably the substrate mean thickness is 0.1 millimeter to 0.4 millimeter.Substrate thickness is measured according to standard EDANA non-woven fleece commercial run, reference method 30.4-89.The bulk density of substrate is 1.0 gram/cm3s, preferably is no more than 0.9 gram/cm3, is most preferably not exceeding 0.7 gram/cm3.
Except being used to make the fiber of substrate, can as known in the art other composition or material be added in the substrate.Desirable additive types depends on the concrete final use of the substrate of being conceived.For example, in the wet wipe goods, become the net goods such as moistening toilet paper, paper handkerchief, face tissue, baby wipes and other similar air, high wet strength is an ideal behavior.Therefore, normally desirable for add the chemical position as wet-strength resins well known in the art to the substrate of cellulose base especially.Introduction about the wet-strength resins type used in field of papermaking is found in the TAPPI monograph No. 29, the technological associations of " wet strength of paper and cardboard ", paper pulp and paper industry (New York, 1965).Except wet strength additives, comprise that some dry strength well known in the art and the velveteen control additive such as amylum adhesive also is desirable.In addition, substrate can also comprise the reagent that improves the base material photometric characteristics as clouding agent, for example titanium dioxide.
According to the present invention, substrate can be made by any method as known in the art.For example, the non-woven fleece substrate can form by the duse process technology, as at overhead pneumatolytic net of paper machine or wet-laying.Other nonwoven production technology as melt and spray, spunbond, acupuncture and spunlaced method also can use.Preferable methods is that water law interweaves.
Substrate can comprise one or more layers, preferred two-layer or trilaminate material.These synusia can be in composite and/or production technology, and perhaps the combined aspects of above-mentioned any material is identical.Preferably wherein one deck can be the scrim enhancement Layer, as described in the U.S. Patent application 09/133294.
According to the present invention, the substrate of wet wipe has the central plate end edge embolium relative with two, that is, and and leading edge embolium and trailing edge sheet.Described each sheet all has first upper surface and second lower surface.
Every folding cleaning piece 1 is gone up from the first guiding end edge 2 in machine direction and extend to the second traction end edge 3 along its length.Folding width of cloth sheet also has the lateral edges 4 and 5 that extends to the second traction end edge 3 from the first guiding end edge 2 at length direction.Every folding cleaning piece 1 can comprise first crease 6 that is roughly parallel to guide edge 2 and is approximately perpendicular to lateral edges 4,5.First crease 6 is spaced apart at length direction and guide edge 2, to be formed on the leading edge embolium 9 that stretches between first crease 6 and the guide edge 2.At this, sheet be between two creases or crease and marginal end portion between the cleaning piece part that stretches.
Folding cleaning piece can also comprise second crease 7, central plate 8 and trailing edge sheet 10.Second crease 7 is parallel to first crease 6 and spaced away at length direction usually.Central plate 8 is attached on the leading edge embolium 9 at first crease 6 place, and extends between first crease 6 and second crease 7.
Trailing edge sheet 10 is attached on the central plate 8 at second crease 7 place.Trailing edge sheet 10 stretches between second crease 7 and traction end edge 3.Cleaning piece is folded to form leading edge embolium 9, central plate 8 and the trailing edge sheet 10 that is in Z-shaped folding configuration at first crease 6 and second crease 7 place, shown in Fig. 2 and 3.In this Z-shaped folding configuration, the part of sheet 9 adjacent sheet 8 and position thereon, the part of sheet 10 adjacent sheet 8 and be positioned at it down.。The folding configuration that yet other is folding such as C shape or J-shaped is folding can be used equally.Except above-mentioned sheet, cleaning piece can have additional sheet in addition.Particularly, leading edge embolium and trailing edge sheet can also form additional folding, thereby form leading edge embolium lip limit (lip) or trailing edge sheet lip limit.These lip limits form by following method: form sheet edge break seam for leading edge embolium or trailing edge sheet, the guide edge of its contiguous folding substrate or trailing edge and separate with it are to be formed on the lip limit of stretching between sheet edge break seam and the end edge.Sheet edge break seam can fold into the leading edge embolium than on the lower surface, thereby the guiding end edge is positioned under the guide edge end flaps.This configuration be convenient to catch aspect the edge useful especially.Another kind of scheme is, the leading edge embolium can be folded into the guiding end edge lean against the leading edge embolium than on the upper surface.This lip limit can also be positioned at the trailing edge sheet than upper surface or than on the lower surface.This lip limit extends to 4 centimetres to 0.1 centimetre of leading edge embolium lip edge break seam or trailing edge sheet lip edge break seams, preferred 2 centimetres to 0.25 centimetre from guide edge or trailing edge usually.
With reference to Fig. 2 and 3, folding cleaning piece 1 is folding mutually between the cleaning piece 1 of adjacent folds.For example, can interlock between the sheet 9 and 8 at the adjacent cleaning piece of folded beneath at the sheet on the folding cleaning piece 1 (as sheet 10).According to the present invention, cleaning piece is piled into array and is disperseed folding cleaning piece.The folding cleaning piece heap layer of a plurality of dispersions then can one makes up on another, forms heap layer as shown in Figure 2.Yet the cleaning piece quantity in disperseing the heap layer and the combination of a plurality of heap layers can change along with needs, depend on the container of their institute's combinations.Particularly preferred folding configuration is described in european patent application 97108388.6, PCT/US98/10603 and EP747313 and is incorporated herein by reference according to the present invention.
According to the present invention, the whole dimension of base material depends on the expectation purposes of cleaning piece and can correspondingly select.A cleaning piece as the indefiniteness of baby wipes, illustrated examples in, every folding cleaning piece 1 can have 10 centimetres to 30 centimetres the length of run of measuring at length direction to traction end edge 3 from guiding end edge 2.Can be 2 centimetres to 7 centimetres for the interval between 1, the first crease 6 of every folding cleaning piece and second crease 7, and the length of leading edge embolium 9 and trailing edge sheet 10 can be 2 centimetres to 7 centimetres.In a preferred embodiment, the interval between first crease 6 and the guiding end edge 2 more preferably is 3 centimetres to 6 centimetres, is more preferably about 3 centimetres and 5 centimetres.Interval between first crease 6 and second crease 7 more preferably is 3 centimetres to 12 centimetres, more preferably 10 centimetres to 12 centimetres.Interval between second crease 7 and the trailing edge more preferably is 3 centimetres to 6 centimetres, more preferably about 3 centimetres to 5 centimetres.
According to the present invention, improved cleaning piece spring divides gets by following method formation: the branch of above-mentioned branch extracting container is got the hole combine with the cleaning piece of accumulation, thereby the average separating force between two adjacent cleaning pieces is 75 gram/sq cm to 250 gram/sq cms, be preferably 100 gram/sq cm to 200 gram/sq cms, more preferably 125 gram/sq cm to 175 gram/sq cms.As determined in the experimental technique hereinafter.Although bound by theory not, it is believed that needs the separating force upper limit preventing the link of cleaning piece, and lower limit has been guaranteed the stability of substrate and prevent that cleaning piece from falling after rise.
According to the present invention, can use separating force between the adjacent cleaning piece to satisfy any way of above-mentioned requirements, comprise physics mode or mechanical system, chemical mode and its combination thus.Preferred these modes should be selected, so that it is to the properties influence minimum of base material itself, thereby cleaning piece keeps its Ideal Characteristics, such as flexibility, absorptivity and wet strength, and can offer the wet wipe sheet in any stage of production process.
For providing the physical/mechanical of separating force to comprise as embossing, wrinkling, hot sticky attached, super sonic, the wet wipe surface adheres to and as the print process of water spray printing.These methods are known for those skilled in the art.Preferable methods is as describing in the U.S. 09/133294 that quotes as a reference, forms the surface topography of peak and paddy at the cleaning piece substrate surface by scrim partly being adhered on another synusia.
Draw, it is hydrophobic that the fiber of formation base material can select to make it, and by forming low friction substrate as long fibre that reduces substrate surface or the fiber that stretches out.The production method that substrate is adopted can be selected equally, thereby forms required separating force.For example, the air net-forming technology is considered to increase separating force, and wet-laying reduces separating force.
The appropriate chemical mode that adapts to separating force between the cleaning piece comprises lubricant, from Dow Corningof Midland, the Syl-Off7677 silicon release coat of Michigan, Syi-Off7048 crosslinking agent are respectively the ratio of 10 parts of 100 parts of ratios by weight can be added to wherein.Another kind of suitable processing method is a UV solidification of silicon coating, comprises the Company available from General Electric, Silicone ProductsDivision, of Waterford, the compound of two kinds of silicon of NY, the name of an article is respectively UV9300 and UV9380C-D1, and ratio is respectively 2.5 parts of 100 parts of ratios.When using this silicon compound, the level that applies on base coating is that every per square meter of surface area is at least 0.25 gram silicon, is preferably 0.5 to 8.0 gram silicon is gratifying, although for depending on that other coating level as the certain applications of basement feature and lotion characteristic has also proved suitable.Other suitable processing material includes, but are not limited to, fluorinated material, and (as, polytetrafluoroethylene (PTFE), the commercial goods is called TEFLON such as fluoropolymer polymer
