By such simple steps, cylinder battery cover 2 can be installed on the cylinder battery 40, and in cylinder battery 40 driving fits.

(execution mode 3)

The cylinder battery cover 3 of embodiment of the present invention 3 is described with Fig. 5 below.

Fig. 5 is the overview of cylinder battery cover 3 of execution mode 3 and the schematic diagram of the installation steps on cylinder battery thereof.

Fig. 5 (a) is the figure of the direction of insertion of expression general survey of cylinder battery cover 3 and cylinder battery 40.Cylinder battery cover 3 shown in Fig. 5 (a) is the bag shape that can insert cylinder battery, when cylinder battery inserts and have the through hole 302 of the energising that is provided with negative pole near the central authorities at the contacted position of end face at the negative pole place of cylinder battery, 2 ends of inserting mouthful this side at cylinder battery are provided with 1 through hole 301a and through hole 301b that is connected by the columniform anodal protuberance of cylinder battery separately.

Fig. 5 (b) is the figure that the expression cylinder battery inserts cylinder battery cover 3 step afterwards.The figure of Fig. 5 (c) to be expression through hole 301a and through hole 301b only blocked state on the anodal protuberance of the cylindrical shape of cylinder battery.

Shown in Fig. 5 (b) and Fig. 5 (c),, make through hole 301a and through hole 301b be positioned on the position that is connected by the positive pole of cylinder battery by through hole 301a and through hole 301b are stretched and bending to the side of the positive electrode of cylinder battery the end at place separately.

In addition, can also exist being provided with more than 2 to be used to the only end of the through hole on anodal protuberance of card.Promptly, increase its width if reduce the number of end, take place crooked in the time of then on blocking the protuberance that ends at positive pole in the end, produce the gap, and the cylinder battery that sheath has been installed becomes and is difficult to be loaded in the use equipment, therefore, can be increased to more than 3 by the number with the end, and the lateral separation between the end with through hole is narrowed down, spill liquid and be difficult between the slit of sheath self, leak thereby make.

In addition, as mentioned above, expectation is with being difficult to make above-mentioned cylinder battery cover 1, cylinder battery cover 2 and cylinder battery cover 3 with synthetic fibers such as the polypropylene fibre of the liquid generation chemical reaction that leaks out from cylinder battery, polyethylene fibre, vinylon or natural fibers such as cotton, wood pulp cellulose.

Yet, the proterties that spills liquid that comes from battery roughly is divided into non-aqueous electrolyte and this 2 class of aqueous electrolyte, as the cylinder battery that has used non-aqueous electrolyte, lithium battery, lithium ion battery etc. are for example arranged, as the cylinder battery that has used aqueous electrolyte, it is primary cell, Ni-MH battery and nickel-cadmium cell etc. that manganese dry cell, alkaline dry battery, nickel are for example arranged.

And problem is: for polypropylene fibre and polyethylene fibre etc., be short of water absorption though have oil absorption, though be fit to the absorption to non-aqueous electrolyte, be not suitable for the absorption to aqueous electrolyte.And on the other hand,, be short of oil absorption though have water absorption for vinylon etc., though be fit to absorption, be not suitable for absorption to non-aqueous electrolyte to aqueous electrolyte.

Certainly, as long as the kind of the cylinder battery of filling determines that the proterties that then spills liquid is also determined, therefore by installing by being fit to spilling the made cylinder battery cover of single raw material that liquid absorbs, when electrolyte take place to leak, can absorb effectively and spill liquid.Yet, in reality, that thereby the cylinder battery cover with assimilation effect is installed is not difficult though the electrolyte of cylinder battery is divided into non-water system or water system, and can not get rid of with mistake does not have the possibility of the cylinder battery cover of assimilation effect to spilling liquid.

Therefore, if when making cylinder battery cover with a kind of raw material of taking into account hydrophily and this two aspect of lipophile, then can the two all absorbs to non-aqueous electrolyte and aqueous electrolyte, but independent a kind of material will have equal substantially hydrophily and lipophile is difficult to, because the material that one of them character is stronger in hydrophily or lipophile is more, thereby can uses the fiber of possess hydrophilic property and have oil loving fiber and make cylinder battery cover.

For example, the blended ratio that obtains of fiber mixing more than 2 kinds can being weaved weaves so that thereby it has retractility manufacturing sheath, also can when weaving, make a kind of fiber make silk earlier, then with the silk twisted of other kind making mixed twisted filament, make sheath thereby this mixed twisted filament woven so that it has retractility.In addition, thus also can weave so that it has retractility and make sheath multiple silk.

That is, when giving retractility by braiding, use these two kinds of fibers of fiber of absorptive fiber and oil absorption, thus, then no matter spilling liquid is aqueous electrolyte or non-aqueous electrolyte, can both be with it absorption.

In order to make cylinder battery cover have retractility, except silk is woven meticulously, the also material that can use raw material self just to have retractility to a certain degree, or by the meticulous twisted of silk being given or being improved retractility.This is the technology that often adopts in the dress material product.Certainly, except lacing, also can carry out bonding or compression with fiber and cylinder battery cover that the cloth made or thin slice manufacturing have retractility, water absorption and oil absorption to multiple class.

In addition, also can form the outside of cylinder battery cover, have the polypropylene fibre or the polyethylene fibre of oil absorption and have raw material such as absorptive cotton, wood pulp cellulose or vinylon in inner apposition with raw material with telescopicing performance.For example, the raw material with telescopicing performance can be made cancellous 2 layers of structure, put into imbibition material at interlayer.And then, can also append liquid-tight coating described later on the outer surface.

In addition, also it doesn't matter even desired liquid-absorbent such as cylinder battery cover 1 raw material such as grade is not high, as long as spill the character that liquid is detained even have a spot of can making.That is to say, when cylinder battery generation leak of liquid, leak to outside amount of liquid, with regard to the damage of the equipment of cylinder battery capable of reducing using as long as can reduce from cylinder battery cover.

Therefore, even yet can not have liquid-absorbent, can make cylinder battery cover yet with raw-material raw material self by the material of methods such as fabricization or porous acquisition liquid-absorbent.

In addition, the raw material of cylinder battery cover 1 grade also can not have the tolerance that can resist the liquid that spills from cylinder battery, this degree of potassium hydroxide solution that for example spills fully from alkaline dry battery.That is to say,, also can alleviate the infringement of cylinder battery being used equipment even cause and to be used again owing to spilling liquid.

To give retractility be easily and simple by silk is woven, but also can make silk self possess retractility.For example, can use the elasticity height, make sheath than rubber more difficult strong aging polyurethane fiber and other fiber.

That is, can use the covering thread that is entwined as core, with other fibers such as polypropylene or vinylon with polyurethane to make sheath, can also use in the weaving operation of cotton etc. the core-spun yarn that polyurethane is inserted core and obtain to make sheath.

The polyurethane raw material are because hydrolysis or be subjected to the influence of airborne nitrogen oxide or ultraviolet ray etc. and the deterioration that is decomposed lentamente, deterioration goes out from raw material are manufactured, through about 3～5 years, produce a large amount of part fractures, but for covering thread or core-spun yarn, owing to also keep telescopicing performance to a certain degree, thereby can be considered to have use value as sheath.

In addition, in order to prevent directly to ooze out by sheath from the liquid that cylinder battery spills, can apply at the film that the outer surface of sheath uses the liquid that spills from cylinder battery to pass through, can improve the performance of cylinder battery cover thus with opaque liquid.Below, such coating is called " liquid-tight coating ".

As the raw material of liquid-tight coating, can consider it is the high rubber such as butyl rubber of high density polyethylene (HDPE) system film or alkali resistance etc.

When particularly using density polyethylene film with high through polyurethane processing as the liquid-tight coating in the inboard, the liquid-tight coating self has retractility, owing to the reason that spills liquid, the elasticity of polyurethane reduces, cylinder battery cover also slowly weakens the adaptation of cylinder battery, thereby can keep and more spill liquid.

In addition, as cylinder battery cover 2, the less cylinder battery cover of ratio that exposes from cylinder battery cover for cylinder battery when carrying out above-mentioned liquid-tight coating in the sheath outside, then can become and spills the more difficult outer cylinder battery cover of sheath that is exuded to of liquid.In addition, in cylinder battery cover 2, if only omit in the processing that requires near the opaque liquid material the through hole 202 of high scalability more in order to insert cylinder battery, then can cheap and making easily.

Wherein, the ratio that the cylinder battery of battery cover 3 exposes from cylinder battery cover is between battery cover 1 and battery cover 2, add man-hour when carrying out liquid-tight at outer surface, it will be retained in ability in the sheath also between battery cover 1 and battery cover 2 from the liquid that spills of cylinder battery 40, be inferior to battery cover 2 though can expect to spill the ability that liquid is retained in the sheath, but because cylinder battery 40 there is no need to pass through among through hole 302, therefore be easy to make than battery cover 2, thereby can think to have manufacturing value.

In addition, poor caring for of the cylindric protuberance of cylinder battery, be difficult under the situation that card ends for for example in cylinder battery cover 1 and cylinder battery cover 3, also can make through hole around have adhesiveness, it is attached on the cylinder battery.

In addition, for example in cylinder battery cover 2, when carrying out the liquid-tight coating at outer surface, entire circumference by making through hole 201 and through hole 202 and above-mentionedly similarly have an adhesiveness, can make these through holes around the positive pole of inner surface and cylinder battery and negative pole bonding on every side, further improve the performance of sheath.That is to say, if from the amount of liquid that spills liquid of cylinder battery in the absorbability of cylinder battery cover 2, just can stop to spill liquid from these through holes outflows.Even when only making wherein either party through hole have above-mentioned adhesiveness, also can stop to spill liquid and from this through hole, flow out.

Certainly, even the outer surface at cylinder battery cover 2 and cylinder battery cover 3 does not carry out under the situation of liquid-tight coating, if spill liquid for a small amount of, then these cylinder battery covers all absorb by spilling liquid, also can prevent from the infringement of cylinder battery filling equipment maybe is reduced to bottom line with infringement.

For example, use ammonium chloride manganese dry cell to spill liquid measure more, but use the manganese dry cell of zinc chloride to begin to increase recently, the manganese dry cell that uses zinc chloride is owing to the carrying out along with discharge absorbs water, thereby the amount that spills liquid also reduces, and therefore, spilling liquid might all be absorbed.

Fig. 8 (d)～Fig. 8 (f) is the figure that expression is installed to the cylinder battery cover 6 of execution mode 6 installation steps on the cylinder battery.Fig. 8 (d) is the figure of the initial step of expression installation.Shown in Fig. 8 (d), at first, the independent face at through hole 602b place that is used for the energising of negative pole covers the negative side of cylinder battery 40, and, anodal protuberance is penetrated in the through hole 601, thereby the semicircular cylinder portion of a side is installed on the cylinder battery 40.

Fig. 8 (e) is the figure of the step in the expression installation process.Shown in Fig. 8 (e), the auxiliary covering part 603b that will be positioned at the upper and lower of the semicircular cylinder portion that has been installed on the cylinder battery 40 covers on the cylinder battery 40.In addition, the semicircular cylinder portion with through hole 602a place side grips towards the direction of cylinder battery 40.

Fig. 8 (f) is the figure of the final step of expression installation.Shown in Fig. 8 (f), the independent face at through hole 602a place covers on the negative side of cylinder battery 40, and the auxiliary covering part 603a that is positioned at upper and lower covers on the cylinder battery 40 from the top of already installed semicircular cylinder portion.

Thus, cylinder battery cover 6 can be installed on the cylinder battery 40.Shown in Fig. 8 (a)～Fig. 8 (f), cylinder battery cover 6 will be installed on the cylinder battery to form 1 columnar mode with 2 semicircular cylinder portions of hinge-type combination.In addition, these 2 semicircular cylinder portions also have auxiliary covering part 603a and auxiliary covering part 603b, with landfill and close the part the gap.Auxiliary covering part 603a and auxiliary covering part 603b are in the gap of landfill sheath, also help and improve 6 pairs of parts that spill the uptake of liquid of cylinder battery cover.

In addition, in the step shown in Fig. 8 (d), also have 2 following steps in more detail: (i) through hole 601 card is ended in the step on the protuberance of the positive pole of cylinder battery 40 and (ii) the independent face at through hole 602b place is covered step on the negative side of cylinder battery.These steps (i) and (ii) any formerly carry out all can.

Fig. 9 (a) is that expression at first blocks the figure that only is installed to the step on the cylinder battery 40 on the anodal protuberance of cylinder battery 40 then with cylinder battery cover 6, and Fig. 9 (b) is that expression only at first blocks cylinder battery cover 6 at the figure that is installed to the step on the cylinder battery 40 on the negative side of cylinder battery 40 then.

The following describes the step shown in Fig. 9 (a).At first, in the anodal protuberance insertion through hole 601 with cylinder battery 40, cover the negative side of cylinder battery then by independent face, thereby the semicircular cylinder portion of a side is installed on the cylinder battery 40 through hole 602b place.And then, make the auxiliary covering part 603b and cylinder battery 40 driving fits of upper and lower, the independent face at through hole 602a place is covered on the negative side of cylinder battery 40.At last, the auxiliary covering part 603a of upper and lower is covered on the cylinder battery 40 from the top of mounted semicircular cylinder portion.

Cylinder battery cover 6 can be installed on the cylinder battery 40 by above-mentioned steps.

In addition, shown in Fig. 9 (b), at first the independent face with through hole 602b place covers the negative side of cylinder battery 40, and the anodal protuberance of cylinder battery 40 is connected in through hole 601, thereby the semicircular cylinder portion of a side is installed on the cylinder battery 40.Then, make the auxiliary covering part 603b and cylinder battery 40 driving fits of upper and lower.And then, another semicircular cylinder portion near cylinder battery 40, is covered the independent face at through hole 602a place on the negative side of cylinder battery 40.At last, the auxiliary covering part 603a of upper and lower is covered on the cylinder battery 40 from the top of already installed semicircular cylinder portion.

Also can cylinder battery cover 6 be installed on the cylinder battery 40 by above-mentioned steps.

Also have, the step of any among Fig. 9 (a) and Fig. 9 (b) all is to penetrate in the through hole 601 by the columniform anodal protuberance with cylinder battery 40 to be limited to anodal protuberance.

In addition, in cylinder battery cover 6, the independent face at the independent face at through hole 602a place and through hole 602b place all has the edge that has formed bend around, becomes the cap shape that covers on the cylinder battery end.From the easy-on angle, this 2 cap shapes part preferably cover in the back that is big a little.For example, if according to Fig. 9 (a) and Fig. 9 (b) step shown in respectively, the cap portion that then makes through hole 602a place is easier to slightly greatly cover than the cap portion at through hole 602b place.

But, as Fig. 9 (a) and Fig. 9 (b) respectively shown in, the magnitude relationship of above-mentioned 2 cap portions is so long as can be overlapping and to cover the negative side of cylinder battery 40 just passable.That is to say that above-mentioned magnitude relationship is so long as just passable in the allowed band of the retractility that raw material had of cylinder battery cover 6.In addition, the relation of 2 cap portions in this cylinder battery cover 6 we can say that the relation of the cap portion in the cylinder battery cover 5 of the relation of the cap portion in the cylinder battery cover 4 with execution mode 4 and execution mode 5 is identical.

In addition, be that 2 " semicircular cylinder portion " also can not be strict hemicycle tubular as above-mentioned cylinder battery cover 4, cylinder battery cover 5, cylinder battery cover 6 major part separately.For example, can be one and account for 60% of cylinder that another accounts for 40%.In addition, even be not 100% passable altogether yet.That is be that semicircular cylinder portion can form a cylindrical shape and cover on the cylinder battery just passable, as long as have 2 major parts.In addition, even the part except through hole can not cover fully, can not lose the effect that can alleviate owing to the damage of the equipment that spills the use cylinder battery that liquid causes yet.

In addition, auxiliary covering part can not be located at the upper and lower of 2 semicircular cylinder portions respectively, also can be arranged on the upper and lower of 1 semicircular cylinder portion.And then, can also only in 1 semicircular cylinder portion, be provided with 1.In addition, its shape also can not be the rectangle shown in Fig. 6 (a) etc.

In addition, even under the situation that auxiliary covering part is not set, also can not lose the protection effect of bringing by semicircular cylinder portion, can alleviate the damage of the equipment of the use cylinder battery that the leakage owing to cylinder battery causes.

That is to say that auxiliary covering part can decide its number, shape and position according to the shape of semicircular cylinder portion, user's requirement and production cost etc.

(execution mode 7)

Each cylinder battery cover of above-mentioned execution mode 4～6 is by with 2 semicircular cylinder portions and close to form 1 cylinder battery cover and constitute as its main shape.In addition, have the also joint close of auxiliary covering part with 2 semicircular cylinder portions of landfill.

But, cylinder battery cover can also have structure as described below, its by 1 semicircular cylinder portion, be positioned at the two ends of semicircular cylinder portion and the position that contacts with the end face at the negative or positive electrode place of cylinder battery be independent face, around independent face, formed the edge that is used to the bend that card ends and semicircular cylinder portion upper and lower auxiliary covering part and form, the cylinder battery cover of this structure is described as execution mode 7.

Figure 10 (a)～Figure 10 (c) is the figure of general survey of the cylinder battery 7 of expression execution mode 7.

Figure 10 (a) is the front view of cylinder battery cover 7, and Figure 10 (b) is the figure when the direction that takes over is slightly observed cylinder battery cover 7.10 (c) are the figure when the direction on more close right side is observed cylinder battery cover 7.

Shown in Figure 10 (b) and Figure 10 (c), the shape of cylinder battery cover 7 is as follows: have the semicircular cylinder portion as main position, the contacted position of end face that the two ends of this semicircular cylinder portion have with the negative or positive electrode place of cylinder battery is an independent face, around the independent face that contacts with the end face of cylinder battery, have and formed the edge that the cylindrical shape that utilizes cylinder battery blocks the bend that ends, in addition, when being installed to semicircular cylinder portion on the cylinder battery, the part of cylinder battery is exposed.And then existence makes the through hole 701 that the positive pole of cylinder battery connects on the independent face at one end, has the through hole 702 of the energising that is used for negative pole on the independent face of the other end.In addition, shown in Figure 10 (a)～Figure 10 (c), there is auxiliary covering part 703 in the upper and lower of semicircular cylinder portion.2 auxiliary covering part 703 have the shape of the exposed portions serve that covers cylinder battery.

Figure 10 (d)～Figure 10 (f) is the figure that expression is installed to the cylinder battery cover 7 of execution mode 7 installation steps on the cylinder battery.The figure of the initial step that Figure 10 (d) expression is installed.Shown in Figure 10 (d), at first, the cylindric protuberance of the positive pole of cylinder battery 40 is limited to through hole 701, then, with the formation of the circumference of independent face the edge card of bend end on the circumference side of cylinder battery 40.

Figure 10 (e) is the figure of the step in the expression installation process.Shown in Figure 10 (e), cover on the negative side of cylinder battery 40 by independent face through hole 702 places, semicircular cylinder portion can be installed on the cylinder battery 40.Then, the auxiliary covering part 703 of upper and lower is covered on the cylinder battery 40, to wrap cylinder battery 40.

Figure 10 (f) is the figure of the state of expression cylinder battery cover 7 after installation on the cylinder battery 40.

So, just cylinder battery cover 7 can be installed on the cylinder battery 40.Shown in Figure 10 (a)～Figure 10 (c), cylinder battery cover 7 be by with a part of opening of curved surface cylindrical portion and near the auxiliary covering part 703 of the upper and lower the peristome function of bringing into play cylinder battery cover.Auxiliary covering part 703 is to cover part that cylinder battery 40 exposes from cylindrical portion, also help and improve 7 pairs of parts that spill the uptake of liquid of cylinder battery cover simultaneously.

In addition, identical with cylinder battery cover 4, cylinder battery cover 5 in execution mode 4,5 and 6 with cylinder battery cover 6, also can not strict half cylinder as the semicircular cylinder portion of the major part of cylinder battery cover 7.As long as the size that is the peristome of cylindrical portion can make cylinder battery insert.In addition, also passable even semicircular cylinder portion and auxiliary covering part 703 can not fully cover cylinder battery.

In addition, also can be unlike each cylinder battery cover of execution mode 4～7 reduce spilling liquid and flow out to the sheath outside by auxiliary covering part, the curved surface of a plurality of semicircle tubulars that constitute cylinder battery cover is overlapping to flow out to the sheath outside to suppress spilling liquid but make by setting.

Figure 11 is the overview that expression possesses the cylinder battery cover 8 of 2 semicircle tubular curved surfaces with overlapped part.

As shown in figure 11, cylinder battery cover 8 is identical with cylinder battery cover 6 with cylinder battery cover 4, the cylinder battery cover 5 of execution mode 4,5 and 6, has the curved surface of 2 semicircle tubulars, by total face combination.But, auxiliary covering part on these 2 semicircle tubular curved surfaces, but become the part shape of coincidence mutually when being installed to cylinder battery on the time.Specifically, on the wall thickness direction of sheath, form the shape that part overlaps mutually.Thus, compare, can further suppress to spill liquid and flow out to the sheath outside, can also improve in addition spilling the uptake of liquid with the situation that does not have intersection.

In addition, in cylinder battery cover 8, also can there be the through hole of the energising that is used for negative pole on the through hole that also exists the cylindric protuberance of the positive pole that makes cylinder battery to connect on the total face, 2 independent faces respectively.

In addition, as implement as described in the explanation in the mode 3, owing to make through hole around have the effort of cementability and carry out the effect that the effort of liquid-tight coating produces at the outer surface of sheath, also can in above-mentioned cylinder battery cover 4～8, bring into play respectively naturally.That is, by above-mentioned effort, can further reduce the discharge that spills liquid to the sheath outside, performance further reduces the effect of the damage of the equipment that uses cylinder battery.

In addition, can also carry out compression process to the cylinder battery cover of the respective embodiments described above, so that cylinder battery can easily be put into the battery case of equipment.Specifically, can make its attenuation by under drying regime, the thickness of cylinder battery cover being compressed.Thus, when liquid spilt from cylinder battery, cylinder battery cover can absorb by swelling expansion and spill liquid.

In addition, for the battery case of accommodating many pieces of cylinder batteries, be installed in cylinder battery cover on the many pieces of cylinder batteries respectively by contact, what flow out from certain cylinder battery cover spills liquid and can be absorbed by other cylinder battery cover.

Figure 12 is the schematic diagram that expression is installed in the cylinder battery cover state of swelling because absorption spills liquid on the cylinder battery.In addition, for following Figure 13,14 is described, supposed to install the cylinder battery cover 2 that outer surface does not carry out the liquid-tight coating.

As shown in figure 12, when cylinder battery cover 2 swellings, become and its corresponding shape of battery case of being accommodated.For example, shown in the figure of lower-left, become whole extended cylindrical shape, or shown in bottom-right graph, become the shape of cuboid.

In addition, can process in advance, it is become and battery case shape corresponding shape cylinder battery cover.For example, when the position of having accommodated cylinder battery is rectangle, then cylinder battery cover is configured as under drying regime and the corresponding shape of its rectangular shape.And then, carry out compression process and make it thin as much as possible.This cylinder battery cover is installed on the cylinder battery, the angle part of its original rectangular shape is accommodated in the battery case corresponding to the angle in the battery case.By such processing, cylinder battery cover is swelling effectively.That is to say that when absorption spilt liquid, the efficient that absorbs was improved in the space between landfill cylinder battery and the battery case effectively.

Owing to as above carry out the liquid-tight coating on the jacket outer surface after the swelling, thereby come from spilling liquid and can oozing out of cylinder battery.This cylinder battery cover note is made A.Under these circumstances, if even and have cylinder battery cover (note the is made B) adjacency in the leeway of a spot of absorption liquid, then can be absorbed by B from least a portion that spills liquid that A oozes out.Thus, can suppress owing to the expansion that spills the equipment damage that liquid causes.

Figure 13 is the general survey schematic diagram of the general battery case of expression.Figure 13 (a) is the overview of battery case 50 upper surfaces, and Figure 13 (b) is the figure when oblique upper is observed battery case 50.

The cylinder battery of cylinder battery cover 2 of supposing in battery case as shown in figure 13 to have accommodated 4 pieces of installations as shown in figure 12 in 50, the situation for when 1 cylinder battery generation leak of liquid wherein describes with reference to Figure 14.

Figure 14 is that the integral body of the cylinder battery cover of expression by a plurality of adjacency absorbs the figure from the state that spills liquid of 1 cylinder battery.

As shown in figure 14,4 pieces of cylinder batteries that cylinder battery cover 2 is installed have been accommodated in the battery case 50.In addition, among the figure, the point on the cylinder battery cover 2 represents to absorb the state that spills liquid.And the close more expression uptake of point is many more.

In addition, 5 figure that begin from the top among Figure 14 be respectively the 1st the stage～figure in the 5th stage.

All do not have at any cylinder battery from the 2nd piece of cylinder battery that the right begins leak of liquid to take place under the state (the 1st stage) of leak of liquid, swelling (the 2nd stage) takes place in this cylinder battery cover 2.Then, from the surface of this cylinder battery cover 2 ooze out spill liquid begin by about cylinder battery cover 2 absorb (the 3rd stage).

Next, the surface of the 2nd cylinder battery cover 2 that begins from the left side also begins to ooze out and spills liquid, and leftmost cylinder battery cover 2 also begins to absorb and spills liquid (the 4th stage).Thus, the liquid that spills from the right begins the 2nd piece cylinder battery is not only absorbed by 2 pieces of adjacent cylinder battery covers 2, is also absorbed (the 5th stage) by leftmost cylinder battery cover 2.

As mentioned above, can also absorb the cylinder battery cover that spills liquid from outer surface and not only can absorb the liquid that from the cylinder battery that self inside comprises, spills, can also absorb the liquid that from other cylinder battery, spills.Thus, spill liquid and can be absorbed with what 1 cylinder battery cover can not be held back by a plurality of cylinder battery covers.That is, can alleviate the infringement that the equipment that uses battery causes owing to the leak of liquid from cylinder battery.

In addition, Figure 14 is illustrated in the leakage under the state of contact the cylinder battery cover of adjacency, even but cylinder battery cover do not contact, wherein certain 1 cylinder battery cover also can absorb the liquid that spills that flows out from other cylinder battery cover.

That is, be preferably the mode of contact, can more effectively absorb the liquid that spills that from other cylinder battery cover, oozes out like this.Yet, even under discontiguous situation,, also can absorb the liquid that spills that from other cylinder battery cover, flows out as long as can absorb from outer surface, can alleviate the infringement of the equipment that uses battery.

In addition, even cylinder battery cover does not contact between mutually when packing battery case into, but when absorbed spill liquid after, consequently swelling enlarges and becomes the state that is in contact with one another with adjacent cylinder battery cover, thus, the cylinder battery cover that is not mounted on the leakage battery also can absorb the liquid that spills from contact-making surface.

In addition, produced the cylinder battery voltage under most of situation that spills liquid and approached 0, and adjacent do not had to produce that the cylinder battery that spills liquid is also residual that voltage arranged.In this case, if also residual have a large amount of absorption of cylinder battery cover of voltage to spill liquid, thereby then make positive pole and negative pole short circuit consume electric power owing to spill liquid.Thus, though have following advantage, that is: produced gas that the voltage on the cylinder battery that spills liquid reduces, produces reduce and spill liquid to spill speed slack-off owing to produce short circuit between positive pole and the negative pole, have the possibility of generating heat and catching fire.

Catch fire in order to suppress above-mentioned heating, can add fire retardant aluminium hydroxide in sheath, the polyparaphenylene benzoxazole fiber that also can use high flame retardant is as one of raw material of sheath.Because polyparaphenylene benzoxazole fiber has high flame retardant, high elastic coefficient and agent of low hygroscopicity, therefore by it is had the uses such as fiber that absorptive fiber or polypropylene fibre etc. have oil absorption with other silk floss or vinylon etc., can make cylinder battery cover with anti-flammability, elasticity and absorbent.

In addition, thereby, also can make the part of the cylinder battery cover that at least one side in the negative or positive electrode with cylinder battery contacts have non-conductive in order to prevent to spill positive pole and the negative pole short circuit that cylinder battery cover that liquid is penetrated into adjacency makes the cylinder battery of adjacency.For example, can with polyethylene or polypropylene etc. to the negative or positive electrode of cylinder battery in the contacted part of at least one side apply, perhaps with polyethylene or polypropylene etc. with the negative or positive electrode of cylinder battery in the contacted part of at least one side on form membranaceous or tabular.

In addition, even what use is

cylinder battery cover

1,3,4,5,6,7 or 8 etc. except cylinder battery cover 2, also can be as shown in figure 14, absorb by the sheath of on the battery that leakage does not take place, being installed and to spill liquid.

In addition, among Figure 14, also to having used a plurality of situations of not carrying out the cylinder battery cover 2 of liquid-tight coating to be illustrated at outer surface.But, on the outer surface of cylinder battery cover, by the position the position in the Outboard Sections of the circumference side that becomes cylinder battery being carried out the liquid-tight coating, can when preventing to spill the effect that liquid flows out to the sheath outside, raising also have the effect that spills liquid that absorption is flowed out from other cylinder battery cover.

Figure 15 is illustrated in the general survey schematic diagram that the cylinder battery cover A～B of liquid-tight coating has been carried out at position outside the part of removing outer surface.

Cylinder battery cover A～D shown in Figure 15 is the above-mentioned cylinder battery cover 2 that has carried out the liquid-tight coating respectively on the outer surface beyond the part of removing the Outboard Sections that becomes the circumference of cylinder battery side.In addition, suppose in the battery case 50 shown in Figure 13 (a) and Figure 13 (b), to have accommodated such 4 cylinder batteries that cylinder battery cover is installed, and according to the sequence arrangement of A～D.

As shown in figure 15, cylinder battery cover A and D do not carry out the liquid-tight coating in the part in left side.In addition, cylinder battery C and B do not carry out the liquid-tight coating in the part of both sides.Above-mentioned part of not carrying out the liquid-tight coating is called " uncoated part ".

That is, cylinder battery cover C is identical with B, and cylinder battery A is identical with D.In addition, the cylinder battery that cylinder battery cover B and D be installed is rightabout mode and the battery case 50 of packing into according to making its side of the positive electrode and the positive pole that the cylinder battery of cylinder battery cover A and C has been installed.

In addition, as shown in figure 15, only there are the uncoated part in cylinder battery A and D on a side, are preferred from spilling the angle that liquid is retained in sheath inside.But, also can there be the uncoated part in the left and right sides as cylinder battery cover C and B, can not lose by himself uncoated yet and partly absorb the effect that spills liquid of partly oozing out from the uncoated of the cylinder battery cover of adjacency.

In addition, even this cylinder battery cover of removing a part and having carried out the liquid-tight coating also can absorption spill liquid when swelling enlarges.At this moment, as described in the explanation of Figure 12, be changed to the profile that the shape with battery case adapts.Perhaps, also can be processed into the profile that adapts for shape in advance with battery case.

Figure 16 is that the integral body of the cylinder battery cover A～D by as shown in figure 15 absorbs the schematic diagram from the state that spills liquid of cylinder battery.In addition, the point on the cylinder battery cover 2 is the same with Figure 14 among the figure represents to absorb the state that spills liquid.Also have, the close more expression uptake of point is many more.

In addition, in Figure 16 (a)～(e), Figure 16 (a) the 1st stage of expression, Figure 16 (b) the 2nd stage of expression, Figure 16 (c) the 3rd stage of expression, Figure 16 (d) the 4th stage of expression, Figure 16 (e) represented for the 5th stage, below, cylinder battery cover A～D abbreviates " A ", " B ", " C ", " D " respectively as.

All do not have at any one cylinder battery from the 2nd piece of cylinder battery that the right begins leak of liquid to take place under the state (the 1st stage) of leakage, swelling takes place in B.Then, spill liquid and begin the uncoated part (the 2nd stage) that uncoated from about the B partly infiltrates C and A.Then, the liquid that spills that oozes out from B begins diffusion inside (the 3rd stage) at C and A.

Next, spill the uncoated part that liquid begins partly to infiltrate from the uncoated in C left side D, spill liquid in D diffusion inside (the 4th stage).Thus, the liquid that spills from the 2nd piece of cylinder battery that the right begins is not only absorbed by adjacent C and A, is also absorbed (the 5th stage) by leftmost D.

As mentioned above, by with the contacted part of the cylinder battery cover of adjacency on the uncoated part is set, the amount that spills liquid in cylinder battery more for a long time, spill liquid and be passed in the cylinder battery cover with this cylinder battery cover adjacency, can prevent or alleviate damage owing to the equipment that spills the tube use type battery that liquid causes.

In addition, beyond the uncoated part, carried out the liquid-tight coating, do not compared, can reduce the amount that liquid flows out to the sheath outside that spills from cylinder battery with making the situation of the intransitable processing of liquid fully.That is, A～D shown in Figure 15 is by above-mentioned 2 kinds of effects, can prevent or alleviate the damage owing to the equipment that spills the use cylinder battery that liquid causes.

In addition, to the

cylinder battery cover

3,4,5,6,7 beyond the cylinder battery cover 2 etc.,, can expect same effect by on the part of this liquid-tight coating, making the uncoated part.

In addition, under the situation that lid is arranged on the battery case, can be with auxiliary absorber, the cylinder battery cover A of Figure 15 can not be absorbed spill liquid completely and assisted absorbent body.

Figure 17 is the figure that is used to illustrate the cylinder battery cover with auxiliary absorber.In addition, in Figure 17,4 cylinder battery covers of cylinder battery have been installed have been made A1, A2, A3, A4, but be identical cylinder battery cover A by note.

As shown in figure 17, with installed cylinder battery cylinder battery cover A uncoated part up, above cylinder battery cover A, place enough thick auxiliary absorber 51, shut the lid of battery case.Dispose auxiliary absorber 51 by above-mentioned steps, it is partly contacted with the uncoated of suitable power with cylinder battery cover A.

By doing like this, when spilling liquid measure more for a long time, spilling liquid can be absorbed by auxiliary absorber 51 by the uncoated part.In addition, the raw material of auxiliary absorber 51 can use the above-mentioned cylinder battery cover that is used for to spill the cited material of raw material that liquid absorbs.

Thus, cylinder battery cover of the present invention can be realized by different shape as each cylinder battery cover of execution mode 1～7.

In brief, cylinder battery cover of the present invention can be with the cylinder battery driving fit and coat the cylinder battery cover of cylinder battery, thereby having the cylindrical shape that utilizes cylinder battery blocks the bend that ends or is used to make the protuberance perforation of anodal cylindrical shape to block through hole that ends and the through hole that is used for the energising of negative or positive electrode, have retractility and liquid-absorbent, and form as one.

In addition, there is no need to cover,, just can absorb and spill liquid as long as can cover at least a portion except that the positive pole of cylinder battery and the All Ranges the negative pole.Also have, so-called herein " driving fit " also can not be all to be closed state completely in sheath is region-wide, also comprises state whole as cylinder battery cover and the cylinder battery driving fit.

In addition, for example auxiliary covering part also can be shirked from the semicircular cylinder portion as the major part of cylinder battery cover, as long as can do as a whole and use when being installed in cylinder battery on the time.

Each cylinder battery of above-mentioned execution mode 1～7 can absorb by its structure separately and spill liquid, can alleviate the damage owing to the equipment that spills the use cylinder battery that liquid causes.In addition, these are simple in structure, can and form at an easy rate.And be an integral body, do not need a plurality of unit constructions and loaded down with trivial details operation such as installation.Therefore, even the user also can easily attach it on the cylinder battery.

In addition, by processing such as liquid-tight coatings, the liquid that spills that can reduce from cylinder battery flows out to the outer amount of sheath.Certainly, so long as in the amount that can store in the inside of each cylinder battery cover, then can prevent to spill liquid fully and flow out to outside the sheath.

In addition, the shape of cylinder battery cover also can not be banded, cylindric or semicircle tubular.

Figure 18 (a)～(c) is the exemplary plot that expression has the shape except the shape of each cylinder battery cover of execution mode 1～7.

For example, though the cylinder battery cover 2 of Fig. 3 is columnar, also can be spherical in shape shown in Figure 18 (a), also can shown in Figure 18 (b), be avette.As long as cylinder battery cover has enough retractilities, then after installation, can be deformed into the shape close with the shape of cylinder battery, therefore can be installed on the cylinder battery and use.

That is to say, this be because: even semicircle, semioval shape, cuboid or other shape, as long as exist the anodal protuberance with cylindrical shape that can utilize cylinder battery to block the through hole that ends, the energising of negative pole is enough big with the through hole retractility that cylinder battery inserts mouthful of holding concurrently, after cylinder battery inserts, convergent force by sheath integral body, as long as have enough convergent forces around inserting mouth, make cylinder battery can not be extruded from inserting mouth, end on cylinder battery in the checkpost that just can stretch on one side, is deformed into the state with the cylinder battery driving fit thus.

In this case, when the anodal protuberance that is used to utilize cylinder battery blocks the through hole that ends when bigger than the diameter of anodal protuberance, skew takes place and produces the gap from battery in sheath, may make and spill liquid and become and spill easily, therefore, be used to the size that through hole that card ends anodal protuberance preferably makes anodal protuberance connect reluctantly, perhaps by around the elongate hole to enlarge the size that the aperture can connect anodal protuberance.

The sensing in Figure 18 (a) left side arrow of tilted direction up and down is the through hole of the negative pole energising usefulness of the expression cylinder battery cover of the doing globulate direction of extension of cylinder battery patchhole of holding concurrently, and the arrow that points to a left side is the direction of insertion of expression cylinder battery with respect to cylinder battery cover.

The sensing in Figure 18 (b) left side arrow of tilted direction up and down is through hole that the negative pole energising usefulness of avette cylinder battery cover is made in the expression direction of extension of cylinder battery patchhole of holding concurrently, and the arrow that points to a left side is the direction of insertion of expression cylinder battery with respect to cylinder battery cover.

To be expression be installed to figure on the cylinder battery with do globulate and the avette cylinder battery cover of Figure 18 (a) and Figure 18 (b) to Figure 18 (c).

Shown in Figure 18 (c), as long as have retractility, just can be by it being installed on the cylinder battery while stretching, thereby with the cylinder battery driving fit, in addition, as long as have first through hole that only can block on the cylindric protuberance of the positive pole of cylinder battery,, also be difficult to skew when mounted with after installing even the shape of cylinder battery cover is not a cylindrical shape; As long as be provided with second through hole of negative pole energising usefulness at the place, diagonal angle of first through hole, just can bring into play the function of cylinder battery cover.That is to say, can focus on production cost and make cylinder battery cover in every way.

Wherein, even to the battery beyond the cylinder battery, also can produce identical with the cylinder battery cover liquid that spills and absorb and use sheath.For example, even for the battery of rectangular shape, also can produce and be used to prevent or alleviate spill the sheath that liquid is given the damage that equipment brought of using it.That is, the present invention also aims to provide the battery cover of a kind of cheapness and easy-to-install rectangular shape, be used to prevent or alleviate leak of liquid owing to the battery of rectangular shape cause damage the equipment of the battery that uses rectangular shape.

That is to say that even in the battery of rectangular shape, also have the same problem of leakage with cylinder battery, the damage that reduces the equipment that causes owing to leakage is important.But even there is a kind of rectangular shape battery cover, it can stop the damage that causes owing to leakage fully, if but cost an arm and a leg, then buying rate is difficult to improve, and the installation rate of the battery cover of rectangular shape also is difficult to improve.Therefore, be difficult to reduce the ratio that the leakage in the equipment of all use rectangular shape batteries damages.So, below, absorb sheath and describe at the liquid that spills of rectangular shape battery.

Under the situation of the battery of rectangular shape, can utilize the protuberance of its anodal protuberance and negative pole to block to end and make battery cover.The battery of rectangular shape described herein is also referred to as " rectangular cell ", is anodal and the protuberance of negative pole is positioned at battery on same.

Figure 19 is used to the overview of card battery cover only and the schematic diagram of the installation steps on the rectangular shape battery thereof with the positive pole of the battery of rectangular shape and negative pole protuberance.

As shown in figure 19, at first, (1) runs through the protuberance of anodal and negative pole respectively in 2 through holes in left side of battery cover 9.Secondly, (2) are limited at the protuberance that keeps battery under the state of 2 through holes in left side, on one side the face with 2 through holes on right side is ended on the protuberance of the positive pole of battery and negative pole from the face side of the battery checkpost that stretches.Under this state, by the retractility that battery cover 9 is had, battery cover 9 and battery driving fit.Thus, also can produce the protuberance that can utilize cylindrical shape battery in addition only blocks and the battery cover of installing.

In addition, if on two faces of the battery cover 9 of the rectangular shape on the end face of and two protuberances of negative pole anodal having of the battery that covers rectangular shape, have to have formed and be used to the only edge of the bend on the battery of rectangular shape of card, the battery cover that then can make rectangular shape becomes more stable with respect to the installation of the battery of rectangular shape.

In addition, if be used to the only edge of the bend on the battery at rectangular shape of card existing on the two sides of the battery cover of rectangular shape to have formed, even the protuberance of then anodal and negative pole also can be installed to the battery cover of rectangular shape on the battery of rectangular shape with the function that through hole does not have card to end.

In addition, can also make the battery cover of rectangular shape with the mode of the cylinder battery cover 1 of execution mode shown in Figure 11.For example, through hole 102 is become 2, be called through hole 102a and through hole 102b.Adjust the size of through hole 102a and through hole 102b,, make through hole 102a, make through hole 102b on the right side of through hole 101b on the right side of through hole 101a so that it can be limited to the negative pole protuberance of the battery of rectangular shape.And then produce the shape of battery cover integral body, as long as in the battery filling department of the equipment that uses battery when the battery that the rectangular shape of battery cover has been installed is packed into the time, battery cover can not be extruded from filling department and get final product.In addition, in the making of rectangular shape battery cover,, also can be formed in left side, upside or downside though be the right side that through hole 102a and through hole 102b is produced in through hole 101a and through hole 101b.

In addition, can also make the battery cover of rectangular shape with the mode of the cylinder battery cover 2 of execution mode shown in Figure 32.For example, the shape of battery cover can be made rectangular shape, on the face relative, make 2 and only can block at the anodal protuberance of the battery of rectangular shape and the through hole on the negative pole protuberance with the patchhole of the battery of rectangular shape.Thus, can make the battery cover of rectangular shape.That is, be used to the bend that card ends having on the face of patchhole to exist, on relative face, exist to be used to the bend that card ends and to be used to 2 through holes that card ends.

In addition, as long as in the cylinder battery cover shown in Figure 18 a and Figure 18 b, make 2 at the opposition side of battery patchhole and can be limited to the anodal protuberance of battery and the through hole of negative pole protuberance, and make the retractility of battery insertion mouth enough big, after inserting cylinder battery, by the convergent force of sheath integral body, as long as insert mouthful around have enough convergent forces, make cylinder battery can not be extruded, just can be used for the battery cover of rectangular shape from inserting mouth.

In addition, can also make the battery cover of rectangular shape with the mode of the cylinder battery cover 3 of execution mode shown in Figure 53.For example, the shape of battery cover can be made the bag shape that the rectangular shape battery can insert, making is used to card only at the anodal protuberance of rectangular shape battery or the through hole on the negative pole protuberance on each end of inserting mouth.Certainly, also can make and be used to card only at the anodal protuberance of the battery of rectangular shape and the through hole on the negative pole protuberance.Thus, can make the battery cover of rectangular shape.

In addition, can also make the battery cover of rectangular shape with the mode of the cylinder battery cover 7 of execution mode shown in Figure 10 7.Can on an independent face, make the through hole that through hole that anodal protuberance uses and negative pole protuberance are used, and the shape of independent face is made the rectangular shape that the battery with rectangular shape adapts.Another independent face also must be made rectangular shape, but does not need to make through hole.Thus, can make the battery cover of rectangular shape.

In addition, with have anodal protuberance and must be useful on card on the relative independent face of the independent face of through hole with through hole and negative pole protuberance and end bend on the rectangular shape battery, but the card with independent face of anodal protuberance and negative pole protuberance ends as long as finishes just passable by the protuberance of bend or anodal and negative pole with at least one side in the through hole.

According to above explanation, battery cover for the rectangular shape different with cylinder battery, in order to address the above problem, rectangular shape battery cover of the present invention is and to cover the battery of above-mentioned rectangular shape with the battery driving fit of rectangular shape, its anodal protuberance and negative pole protuberance that has on the same one side that is used to utilize the battery that is present in above-mentioned rectangular shape blocks the through hole that ends, have retractility and liquid-absorbent, can form as a whole.

In addition, for the rectangular shape battery cover different with cylinder battery, in order to address the above problem, rectangular shape battery cover of the present invention can also be with the driving fit of rectangular shape battery and cover the rectangular shape battery cover of above-mentioned rectangular shape battery, it has the rectangular shape that is used to utilize above-mentioned rectangular shape battery and blocks the bend that ends and be used for the positive pole of above-mentioned cylinder battery and the through hole of the energising of negative pole, have retractility and liquid-absorbent, can form as a whole.

In addition, the size of the through hole 401a of the cylinder battery cover 4 of execution mode 4 as shown in Figure 6 and through hole 401b also can be different.Because card only is present on each independent face with bend, even therefore through hole 401a and through hole 401b's varies in size, also can be installed on the cylinder battery, among through hole 401a and the through hole 401b any as being used to the only through hole on the anodal protuberance of cylinder battery of card, can be installed on the cylinder battery.But, in this case, the positive pole of cylinder battery must be installed cylinder battery cover towards the independent face side.As long as any among through hole 401a and the through hole 401b is reserved as energising and is limited to the through hole of the anodal protuberance of cylinder battery, have this protuberance card and end the top that independent face with through hole is positioned at another independent face and be installed on the cylinder battery by making, can form thus and more be difficult to the cylinder battery cover that is offset.

In addition, the size of the through hole 201 that had of the cylinder battery cover 2 of execution mode 2 as shown in Figure 3 also can be ended irrelevant with the card of the cylindric protuberance of the positive pole of cylinder battery 40.If the card that through hole 201 does not possess anodal protuberance ends function, then skew easily, and to spilling the reserve capability variation of liquid, but since have through hole 201 face around bend only can block on the circumference side of cylinder battery 40, therefore also sheath can be installed on the cylinder battery 40.And then, if through hole 201 is the same with through hole 202, be the size that can be used for inserting cylinder battery, then cylinder battery can insert in through hole 201 and the through hole 202 any, and cylinder battery promptly can also can insert in the sheath from negative side from side of the positive electrode.

In addition, the size of the through hole 701 that had of the cylinder battery cover 7 of execution mode 7 as shown in figure 10 also can be ended irrelevant with the card of cylindric protuberance on cylinder battery 40 positive poles.As long as be enough to card only on the circumference side at cylinder battery 40 at the width that has formed the edge of bend around the independent face with through hole 701, the independent face that then has through hole 701 can block only on cylinder battery 40.When through hole 701 was big, the positive pole of cylinder battery 40 can be installed cylinder battery cover no matter towards the independent face with through hole 701 or have any side in the independent face of through hole 702.

In addition, in cylinder battery cover shown in Figure 11 8, also can only on an independent face, exist and be used to the only through hole on anodal protuberance of card.In this case, energising is covered the side of the positive electrode of cylinder battery with the independent face at through hole place, and then cover anodal protuberance card, can make sheath be not easy to be offset like this with battery only with the independent face at through hole place.

In addition, though cylinder battery cover 1～7 has been represented the example of one-piece type cylinder battery cover, cylinder battery cover can not be one-piece type also.

Link the positive pole of cylinder battery and the end face parts of negative side with elastomers such as rubber, between elastomer and battery, sandwich as the sheet sheath that spills the absorber of liquid, then battery is packed into and use in the equipment of battery, so also can spill the absorption of liquid effectively.

Figure 20 will sandwich the schematic diagram of the assemble method of the cylinder battery cover between elastomer and the battery as the sheet sheath of absorber.

Figure 20 (a) is that expression is used for the sheet sheath is installed to the state of erecting tools 12 before being mounted on the cylinder battery on the cylinder battery.

Erecting tools 12 is that end face by 2 donut-like of two end faces that cover cylinder battery is with parts 10 and link these 2 end faces and constitute with 4 elastomers 11 of parts 10.The natural length of elastomer 11 likens to the length of the cylinder battery of mounting object shorter, if erecting tools 12 is assembled on the cylinder battery, then restoring force plays a role, and 2 end faces are compressed on two end faces of cylinder battery with parts 10.

At first, shown in the arrow of Figure 20 (a), use between the parts 10, insert cylinder battery at the positive pole of cylinder battery and the end face of negative side.

Figure 20 (b) is expression as the sheet sheath 13 of the absorber state before between the elastomer 11 that is clamped into cylinder battery and erecting tools 12.Arrow is represented sheet sheath 13 is sandwiched between cylinder battery and the elastomer 11.

Figure 20 (c) is illustrated in the state that has sandwiched the sheet sheath between the elastomer of the parts that are used to sandwich the sheet sheath and the cylinder battery.Like this, will be installed on the cylinder battery by the cylinder battery cover that erecting tools 12 and sheet sheath 13 constitute.

Figure 20 (d) is that expression is provided with the used ditch of elastomer that erecting tools 12 has 11, when cylinder battery being packed into use equipment, can the part that the sheet sheath is thin be configured on the corresponding part in upper surface, lower surface, front surface and rear surface with battery.Thus, can easily the sheet sheath be installed on the cylinder battery, the cylinder battery that the sheet sheath has been installed also is encased in the use equipment easily.

Figure 20 (e) is the state after expression use erecting tools 12 is installed to the sheet sheath shown in Figure 20 (d) on the cylinder battery.

The advantage of such cylinder battery cover is, can make the sheet sheath respectively.That is, one-piece type cylinder battery cover be basically single model use can only be applicable to single model, what single three models were used can only be applicable to single three models, is difficult to be installed on the battery of other size.But, erecting tools 12 shown in Figure 20 (a) is such passes through elastomers such as rubber link the end face of the positive pole of cylinder battery and negative side with parts erecting tools, can be shared in single model and single two models, single two models and single three models etc., and the sheet sheath can be made the sheet supply of default size.Thereby the user can be cut into the size of wishing separately and be used.Consequently can reduce cost.

Thus, the present invention can provide a kind of cheapness and install, is used to alleviate the cylinder battery cover of the damage that causes owing to the cylinder battery leakage easily.

The present invention can alleviate the damage of the equipment of the use cylinder battery that causes owing to the cylinder battery leakage.Therefore, be the cylinder battery cover that the equipment of cylinder battery is used in a kind of useful being used to.In addition, cylinder battery cover structure of the present invention is also simple, can make at low cost, and easy operating.Therefore, the used for dry cell sheath as plurality of devices such as the remote controller that is used for video equipments such as TV and video tape recorder, toy, flashlight, clock, broadcast receivers is useful.
