Abstract
There is provided single ply labels for labelling dry cell batteries having elongate peripheral case (16) defining an axis and opposed ends enclosing a direct current, electrical energy providing core (12). The label is formed of a transparent, self supporting, substantially monoaxially oriented, heat shrinkable polymer film backing (26) having an outer surface and an inner surface, a width sufficient for the backing to embrace the battery case and provide, at opposed ends, first (32) and second (34) edges which extend parallel to the axis of the battery and meet in at least abutting relationship, and a length for extending beyond the opposed ends of the battery and lap over onto the opposed third (36) and fourth (38) ends of the battery. An alkali resistant, electrically non-conductive, opaque pigmented layer (28) is applied to the inner surface of and supported by the backing. An electrically non-conductive, pressure-sensitive adhesive layer (30) is applied over the pigmented layer at least along the first (32) and second edges (34). The pressure-sensitive adhesive has sufficient peel adhesion to prevent lifting of an applied label from the case of the battery and sufficient shear strength to prevent relative movement of adhered first edges on heat shrinkage of an adhesively applied backing about the battery case (16).
Description
Dry cell is the most universal portable electric energy source.They comprise photoflash lamp, instrument, toy, appliance batteries, and other similar batteries.Dry cell occurs with various structures and voltage output, and they can be single use battery or a plurality of use battery.The most universal size is " AA ", " AAA ", " C ", " D " and " 9 volts " battery.Except that some other structure, AA, AAA, C and D size cell are also utilized at least one to provide and are used as the metal cylinder shell of the drawing of positive termination electrode, and the end as negative pole.Anodal and negative pole is separated by insulant.
In early days in the battery, on battery case, apply and be used for showing the figure of battery information to the user.Figure is shown to the metal foiled paper covering that is used for battery case then.The metal foiled paper covering is now mainly replaced by the label based on use multilayer polymeric shrink film, and the most universal polymeric material is a polyvinyl chloride.Employed sandwich construction promptly is " three layers " and " bilayer " structure that this area was called, and is the most common with three layers.
Reference is the accompanying drawing of title with " prior art ", three-decker comprises a composite laminate, promptly on the first pyrocondensation self-supporting polymer film (2), apply the metal (4) that one deck normally forms with vapour deposition, the additional second self-supporting thermal polycondensation compound rete (2 ') on it; A graph layer (6); And a top protective layer, i.e. another self-supporting thermal polycondensation compound rete (2 ").Lower surface at rete (2) applies a pressure-sensitive adhesive layer (8).
In double-decker, save the first intermediate heat condensed polymer layer (2 '), so that a lamination to be provided, promptly on the first thermal polycondensation compound rete (2), provide metal level (4); Nonferrous layer (6); And thermal polycondensation compound layer (2 ").Give pressure-sensitive adhesive layer (8) in thermal polycondensation compound rete (2) primary coat again.In two kinds of structures, especially between self-supporting thermal polycondensation compound layer and metal level, when combination is more weak, utilize layer of adhesive to improve the intensity of combination usually.The bonding label of multilayer is for example at the United States Patent (USP) 4,801,514,4,911,994,5,032,477,5,262,251 and 5,312 that belongs to people such as Will, narration in 712, and each self-reference is introduced here.
All trials have been made, so that metal level is moved on between thermal polycondensation compound rete and the pressure-sensitive adhesive layer between self-supporting thermal polycondensation compound rete.A kind of so not comprising uses the structure of shrinking polymeric membrane belonging to Sharklett, and narration in the United States Patent (USP) 5,292,566 of III is here with reference to introducing.Yet a critical limitation of this structure is a little less than the combination of metal pair polymer layer, and metal level is subject to be used for add the online impact force action of lot number and date code information and break to label.The known metal level part that breaks penetrates soft relatively pressure-sensitive adhesive layer, and makes battery short circuit, causes that electric energy dissipates.
Once the method for doing to attempt on the another kind of market is to solidify lacquer with ultraviolet ray to replace top layer thermal polycondensation compound film (2 ").This structure is narration in the United States Patent (USP) 5,190,609 that belongs to people such as Lin, here with reference to introducing.Have been found that these labels only by limited acceptance, close because verified this coating is a weak bond, show inferior resistance to wear and inferior anti-changes in environmental conditions.
Sandwich construction also exists matches the shrinkage character of which floor polymeric membrane, so as when pyrocondensation between adjacent heat condensation polymerization rete the problem of fricton-tight appearance.If not like this, then figure deformation can appear, wrinkle and possible absciss layer.Double-decker also presents the problem of label from battery case protuberance and inferior environmental aging.
It is desirable to provide a kind of pressure-sensitive adhesion single layer structure that is used for wrapping up battery case.Single layer structure will be more cheap than the multilayer labels structure of using now.
The individual layer battery label that works must have the useful life more than 5 years, and does not present owing to comprise that circulation is exposed to more than 150 °F temperature and near the caused all losses of the ambient pressure of 100% humidity.The more important thing is single layer label must suitably stand because of the interests that do not have existing other layers from makers' strict demand, the characteristic of other layers can be used for increasing or change the characteristic of individual layer, to solve manufacturing and ambient pressure.
Therefore, although cost and production interests are arranged, yet the single layer label structure makes function battery volume maximum by reducing label thickness, make battery manufactory in total battery structure of fixed outer size, fill long-pending more energy thus, so provide a kind of effective single layer label to be still the ongoing exploration in this area.
According to the invention provides the single layer label that is used for dry cell, this dry cell provides a circumference shell and direct current energy of sealing to supply with the opposite end of core.This label forms with the polymeric membrane lining or the backing of transparent, self-supporting, uniaxial orientation, pyrocondensation, and backing has certain width and length.The width of backing provides the first and second relative longitudinal edges in its end, this width enough makes backing surround battery case, so that first limit and second limit are met by opposite joining relation at least.The length of backing enough makes backing extend to outside the battery case length, and this length provides the first and second relative circumferential edge in its end, when their adaptations when battery case wraps up extend to outside the battery case length.The non-conductive nonferrous layer of opaque alkali resistant covers any witness marking that prints on the backing lower surface, and it also is printed on the lower surface of backing and by the backing support.A non-conductive pressure-sensitive adhesive layer extends along first limit of backing and the length on second limit at least, preferably the periphery around backing extends, and inwardly enough extend from several relative edges of backing, to guarantee at least each opposite end of battery and bonding contact of circumference shell of battery.Preferably contact adhesive extends on whole nonferrous layer.Contact adhesive has enough shearings or adhesion strength, preventing backing at least around the battery circumferential pyrocondensation, and enough peel adhesion strength, swell from battery case along battery length to prevent label.
This label is applied on the outer surface of battery case, and by contact contact adhesive and attached on the battery case.Label is wrapped up around battery case, first limit and second limit are docked at least, stretch out outside the battery case on the 3rd limit and the 4th limit.Make by heat effect on the heat shrinkage film on the opposite end of external part shrink wrapped at battery of label.
For purposes of the invention, if in 24 hours the effect of 7.2N KOH is had anti-saturating property in immersion test, nonferrous layer just thinks to have alkali resistance, if resistance is approximately greater than 560 megaohms (560 * 10
6Ohm), nonferrous layer just thinks to have anti-conductivity.
Preferred adhesive is based on the acrylic pressure-sensitive adhesive of solvent at present.Can use latex or thermosol contact adhesive effectively equally.Preferably contact adhesive provides at least about 2Pli (pound/inch) at present, preferably about 2Pli is to peel strength or the peel adhesion strength of 5Pli, at least 4,000 minute, preferably about 4,000 minutes to 10,000 minutes shear strength, and 2Pli at least, preferably about 2Pli is to the mutual button viscosity (loop tack) of 4Pli.
Preferred backing has about 60% in periphery or peripheral direction, preferably about 20% to 60%, more preferably about constriction coefficient of 40% to 50%.Contraction is a machine direction along the width of backing.At present preferred backing is the polychloroethylene film of transparent uniaxial orientation, and about 2mil is thick.
Accompanying drawing is that three layers of part explanations and double-layer label structure of title with " prior art ", and they represent present bonding battery label structure.
The relation of Fig. 1 and label and battery case together illustrates the perspective view of each layer details of single layer label of the present invention.
Fig. 1-A except that adhesive layer around two on label periphery extends, represent the structure identical with Fig. 1.
Fig. 2 represents to be wrapped in battery single layer label of the present invention on every side by opposite joining relation.
Fig. 3 explanation makes the external part pyrocondensation of label to the opposite end of battery by heating.
Fig. 4 illustrates with single layer label of the present invention to come to the tagged a kind of mode of battery.
According to the present invention, be provided for the single layer label of dry cell and the battery of the such label of clad.
The battery of clad single layer label of the present invention comprises cylindrical " AA ", " AAA ", " C ", " D " size cell.The label that is used for such battery surpasses battery length, and the label end can be folded on the battery opposite end when shrinking.Label of the present invention can also be used for any other dry cell structure, and does not require with cylindrical AA, AAA, and C and D size cell are electric consideration.Other such battery structures include but not limited to popular Voltaic battery.
With reference now to Fig. 1,, Fig. 1-A, Fig. 2 and Fig. 3, typical cylindrical stem battery 10 supplies with core 12 by an electric energy that preferably forms with basic matterial and an electrode 14 is formed.They both by cylinder blanket 16 suits, cylinder blanket 16 provides an anode end cap terminal 18 and negative pole end cap ends 20.Anodal and core 12 is electrically connected, and negative pole and electrode 14 are electrically connected.Shell 16 and end cap 20 are by annular insulant 22 insulation of suitable electrically non-conductive material.The part of positive endcap electrode 18 and negative terminal lid electrode 20 and individual layer battery label of the present invention 24 contact in inside.
Shown in Fig. 1 and Fig. 1-A, individual layer battery label 24 is made up of three main layers: a self-supporting shrink wrap layer 26; Supported alkali resistant nonferrous layer 28 for one, it is non-conductive in the zone that it extends on the cell section 16 and 20 of battery case at least; And one supported pressure-sensitive adhesive layer 30, and it is non-conductive in the part that it extends on the parts 16 and 20 of battery case at least.Extend on first limit 32 and second limit 34 parallel with battery shaft shown in the pressure-sensitive adhesive layer 30 necessary edges.Limit 32 and 34 will be done to dock or can be overlapping.Provide adhesive to guarantee that contact adhesive contacts with battery case on each limit on four limits.Ideally, shown in Fig. 1-A, contact adhesive extends around the periphery of label 24, and first limit 32 and second limit 34 and the 3rd limit 36 and the 4th limit 38 promptly are provided.More typically, as shown in Figure 1, pressure-sensitive adhesive layer 30 extends on the whole surface of layer 26.Pressure-sensitive adhesive layer 30 is local non-conductive in its contact component 18 and 20 at least, to prevent from positive pole to the negative pole current drainage.Nonferrous layer 28 is also non-conductive with the place that two electrodes of battery 10 contact at them with thermal polycondensation object plane material or backing 26.The non-conductive nonferrous layer that saves existing frangible vacuum deposited metal layer is to use the key of individual layer support.
Another key that individual layer battery label can be provided is to consider the suitable lining of selecting under the manufacturing parameter.Must be that lining is realized a kind of network structure with single self-supporting layer, it must play equivalent action with the multilayer of using in the past, here at lining lower surface printed pattern, applies adhesive on the figure of lower surface printing like this.In the past, when using a plurality of self-supporting layer, one deck can replenish another layer, or change or improve certain specific character, so that make label be fit to makers' strict demand.In the present invention, individual layer must provide the function of multilayer, and still makes label thickness minimum.This can not realize to sacrifice to produce.Individual layer will increase production cost greatly because if migrate, and then the increase of production cost will be offset the advantage of individual layer.In addition, single supporting film must pyrocondensation, and still enough nonelastic, so that when various printed field are combined in the multiple color that is used for formation information and fine arts figure of printing, and the distortion during the tolerance duplicate record.For such operation, will add about 6 to 10 kinds or more color to film.Film must oppositely not stretch, otherwise when record displacement will be arranged, and hinders print distinctness, and this will not be accepted on market.Simultaneously, film must have certain degree of shrinkage along machine direction, so that when heating the end of the label that applies can be folded on the end of battery, and does not make the figure deformation on the film.If excessive withdrawal or contraction are arranged, film can swell at seam crossing, exposes adhesive, and adhesive can be that dirt is collected the source, and this is the not received result of another kind.In addition, the unsuitable contraction of seam crossing can cause protuberance, brings undesirable outward appearance like this from beautifying angle.Considering these purposes, and be that per minute reaches 800 batteries to " AA " size speed of production in the machine that tags, is 600 of per minutes or more batteries to " AAA " battery, makes the self-supporting layer of label construction reach following explanation standard.
The lining or the backing 26 that are used for single layer structure are the uniaxial orientation polymer film, and it only along the direction perpendicular to battery shaft, promptly is orientated along the backing Width and around battery circumferential substantially.According to speed of production, in this direction, promptly can reach about 60% in machine direction or the contraction on 34 directions of 32 to second limits, first limit, generally about 20% to about 60%, and preferably arrive in about 50% scope about 40%, be about 40% to about 45% most preferably, to being 40% to 50% than macrocell to smaller batteries.
It is about 10% that the remaining withdrawal of duration of storage should be not more than, preferably less than 8%, more preferably less than about 3%.
At perpendicular axially also some contraction may appear.For perpendicular direction, be contracted in-2% to+5%, preferably 0 to 3%, more preferably about 0 to 1% in a direction.Negative contraction means elongation.
At present the mechanical property of preferred film is at the about 15Kpsi of machine direction paper tinsel intensity, and is about 77% in machine direction elongated, and at machine direction modulus of elasticity 400Kpsi, all according to ASTMD882-91 (test method A).
The at present preferred preferably about 2mil of pyrocondensation rete 26 is thick, and is the polychloroethylene film of cardinal principle uniaxial orientation, and by American Mirrex Corp.of New Castle, Delaware makes.
