【従来の技術】たとえば、LR03型アルカリ電池などの筒形密閉電池では、その使用あるいは取り扱いを誤った場合に、電池の内圧が異常上昇して外形容器が爆発的に破裂する危険がある。 BACKGROUND ART For example, in a cylindrical sealed battery such as LR03 type alkaline battery, when the wrong its use or handling, there is a risk that the internal pressure of the battery outer container rises abnormally ruptures explosively.

【0003】この危険を防止する手段としては、外形容器の気密封止(シール)材をなすガスケットの一部に局所的に破断しやすくした防爆安全弁を一体形成することが行なわれているが、外形容器の爆発的破裂をさらに確実に防止するためには、つまり安全性をさらに高めるためには、電池の外形容器そのものに直接、防爆安全弁を形成することが望ましい。 [0003] As means for preventing this danger, it has been performed to integrally form the explosion-proof safety valve which easily locally broken part of the gasket forming a hermetic seal (sealing) material outer container, to further securely prevent explosive rupture of outer container, in order to further enhance i.e. safety, directly to the outer shape container itself of the battery, it is desirable to form the explosion-proof safety valve. この防爆安全弁は、外形容器の一部に、その容器内圧の異常上昇によって先行開裂する溝条の破断誘起条を設けることによって形成される。 The explosion-proof safety valve, a portion of the outer container is formed by providing a breaking induced conditions groove shall be preceded cleaved by abnormal increase in the internal pressure of the container.

【0004】図6は、外形容器に上記防爆安全弁を設けた密閉電池の外形状(A)およびその包装体(B)を示す。 [0004] Figure 6 shows the outer shape (A) and packaging of the sealed battery provided with the explosion-proof safety valve to the outer container (B). 同図に示す電池1は、たとえばLR03型アルカリ電池をなすものであって、電池1の本体は、(A)に示すように、発電要素(図示省略)を密閉収納する円筒状外形容器2の一方の閉塞端面部21に、その端面部21 Battery 1 shown in FIG. 1, for example be those which form a LR03 type alkaline batteries, the main body of the cell 1 (A), the cylindrical outer container 2 for sealing housing the power generating element (not shown) at one closed end face 21, its end surface 21

【発明が解決しようとする課題】しかしながら、上述した技術には、次のような問題のあることが本発明者によってあきらかにされた。 [SUMMARY OF THE INVENTION However, the above-described technique, it the following problems have been revealed by the present inventors.

【0006】すなわち、上記防爆安全弁が設けられた筒状外形容器の閉塞端面部は、その防爆安全弁が形成された部分での強度が他の部分よりも低くなっている。 Namely, the closed end face of the cylindrical outer container the explosion-proof safety valve is provided is lower than the intensity of other parts of the portion where the explosion-proof safety valve are formed. この部分的な強度低下は通常の電池使用には支障無い程度のもので、たとえば使用者が電池を機器に装填するときなどに1本だけを誤って落とすことがあっても、これだけで致命的な損傷を受けるようなことは通常ない。 This partial decrease in strength for normal battery use intended degree no problem, for example, even the user there be accidentally dropping only one, such as when loading a battery device, this alone fatal a thing is not usually receive dAMAGE.

【0007】しかし、上記防爆安全弁が強度上の弱点となっていることは否めず、通常の落下でも、その条件によっては致命的な損傷を受けることがある。 However, it is not denied that the explosion-proof safety valve has a weak point of the strength, even in a normal fall, depending on its condition may be subjected to permanent damage. たとえば、 For example,
多数本の電池をまとめて包装した電池包装体では、その包装体を誤って落下させた場合に、その包装体の総重量による落下衝撃が生じる。 In the battery package which is packaged together large number of batteries, when dropped accidentally its packaging, drop impact is caused by the total weight of the packaging. この落下衝撃が包装体の中の1本だけの電池の突起端子部に加わると、図7に示すように、その衝撃によって上記防爆安全弁の部分に開裂や変形等の破損が生じ、これにより電池は使用不能になってしまう。 When the drop impact is applied to the protruding terminal of the battery of only one in the package, as shown in FIG. 7, breakage such as cleavage or deformation in the portion of the explosion-proof safety valve caused by the impact, thereby batteries it becomes unusable.

【0008】このように、筒状外形容器の一方の閉塞端面部に突起端子部と防爆安全弁を形成した筒形密閉電池では、上記防爆安全弁が強度上の弱点となるために十分な耐衝撃性を持たせることができない、という問題があった。 [0008] Thus, in one cylindrical sealed battery forming the protruding terminal portion and the explosion-proof safety valve to the closed end face of the cylindrical outer vessel, sufficient impact resistance to the explosion-proof safety valve is a weak point of strength it is not possible to have, there is a problem in that.

【0009】上記問題の解決手段としては、強度上の弱点となる個所にスポンジ等のクッション材をあてがい、 [0009] As a solution to the above problem, Ategai a cushioning material such as a sponge a location that will be used as a weak point of the strength,
落下等の衝撃をそのクッション材に吸収させることが考えられる。 Thereby absorbing the impact such as a drop in the cushion material can be considered. しかし、クッション材で所定の衝撃吸収効果を得るためには、容積的にかなりの量のクッション材を使用する必要があり、このことが電池の包装サイズを著しく増大させて、運送や販売等の流通面で大きな不利を来す、といった別の問題を生じてしまう。 However, in order to obtain a predetermined impact absorbing effect by the cushion material, it is necessary to use a cushion volumetrically significant amounts, this is significantly increase the packing size of the battery, transportation and sales etc. It causes a significant disadvantage in the distribution surface, occurs another problem.

【0010】この発明は、以上のような問題に鑑みてなされたもので、その目的は、筒状外形容器の一方の閉塞端面部に突起端子部と防爆安全弁を形成した筒形密閉電池において、電池の外形サイズあるいはその包装体のサイズを増大させることなく、落下等に対して十分な耐衝撃性を備えた筒形密閉電池および電池包装体を提供することにある。 [0010] The present invention has been made in view of the above problems, the object thereof is cylindrical sealed cell formed one protruding terminal portion and the explosion-proof safety valve to the closed end face of the cylindrical outer container, without increasing the size of the external size or a package of batteries is to provide a cylindrical sealed battery and a battery package having a sufficient impact resistance against falling or the like.

【0011】 [0011]

【0014】さらに、上記保護部材は電気絶縁性なので、その保護部材が閉塞端面部全体を覆うキャップ状に形成された場合には、未使用時での不意の短絡や放電を防止することができるとともに、その保護部材の有無によって電池の新品/使用済みを個別に識別する目安を提供することができる(請求項2)。 Furthermore, since the protective member is electrically insulative, if the protective member is formed in a cap shape that covers the entire closed end surface portion, it is possible to prevent short circuit and discharge unexpected in Unused together, it is possible to provide individual identifying omissions new / used batteries according to the presence or absence of the protective member (claim 2).

【0015】また、上記保護部材が突起端子部の上方を開放するリング状に形成されるとともに、そのリングの上側端面に上記突起端子部とほぼ同じ高さの環状防護面を形成した場合には、その保護部材を嵌着させた防護状態のままで電池端子への電気接続を行なわせることができる(請求項3)。 Further, if the protective member is formed is formed into a ring shape which opens above the projection terminal portion, a substantially annular protective surface of the same height as the projecting terminal portion on the upper end face of the ring , it is possible to perform the electrical connections to the battery terminals while protection state of being fitted to the protective member (claim 3).

【0016】さらに、本発明では、発電要素を密閉収納する筒状外形容器の一方の閉塞端面部に突起端子部と防爆安全弁が形成された筒形密閉電池を複数本まとめて包装した電池包装体において、非クッション性の剛性材質で構成され、上記防爆安全弁よりも外側で上記閉塞端面部の縁に沿った環状部分に着座する環状脚部と、この環状脚部に支持されて上記防爆安全弁を覆うとともに上記突起端子部と同じかそれよりも若干高い位置に防護面を形成する防護蓋部とが一体に形成された電気絶縁性の保護部材を、上記包装体内の各電池の一方の閉塞端面部にそれぞれ嵌着させる構成とした。 Furthermore, in the present invention, a battery package which was packaged either cylindrical sealed batteries protruding terminal portion and the explosion-proof safety valve are formed on the closed end face of the cylindrical outer container for sealing housing the power generating element plural together in consists of a rigid material of non-cushioning, and annular leg to be seated in an annular portion along the outside to the edge of the closed end face than the explosion-proof safety valve, the explosion-proof safety valve is supported on the annular leg the electrical insulating protective member and the protective cover portion is formed integrally to form the same as or protective surface slightly higher position than the projecting terminal portion, one of the closed end face of each cell of the packaging body to cover each was configured to be fitted to the part.

【発明の実施の形態】以下、この発明の好適な実施形態について、添付図面に基づき詳細に説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. なお、各図間にて同一符号を付した部分は同一または相当部分を示すものとする。 Note that portions denoted by the same reference numerals in between the figures denote the same or corresponding parts. 図1はこの発明による筒形密閉電池の外形およびその要部の断面を示す。 Figure 1 shows a cross section of the profile and its main part of the cylindrical sealed battery according to the present invention.

【0019】同図に示す電池1は、まず、発電要素を密閉収納する筒状外形容器2の両閉塞端面部21,22に電池の両極端子が形成されるとともに、正極端子となる側の閉塞端面部21にて凸状に突出する突起端子部23 The cell 1 shown in the figure, first, the extreme terminal of the battery is formed on both the closed end surface 21, 22 of the cylindrical outer container 2 for sealing housing the power generating element, the a cathode terminal side closure projecting terminal portion 23 protruding in a convex shape in the end surface portion 21
が形成された構造を有する。 There has a formed structure.

【0020】筒状外形容器2は、詳細な図示を省略するが、正極端子を兼ねる有底筒状電池缶の開口部を負極端子板を含む封口体で閉塞することにより形成される。 The cylindrical outer container 2, although not shown in detail in the drawings, is formed by closing the opening of the bottomed cylindrical battery can serving as a positive electrode terminal with a sealing member comprising an anode terminal plate. 正極の突起端子部23はその筒状電池缶の底面部に一体形成されている。 Projecting terminal portion 23 of the positive electrode is integrally formed on the bottom surface of the cylindrical battery can.

【0021】突起端子部23が形成された閉塞端面部2 The closure projecting terminal portions 23 are formed end face 2
1には防爆安全弁3が形成されている。 Explosion-proof safety valve 3 is formed at the 1. この安全弁3は溝状の破断誘起条31によって形成される。 The safety valve 3 is formed by a fracture inducing Article 31 of the groove-like. この破断誘起条31は、たとえば同図に示すように環状のラインパターンを形成し、容器2の内圧が異常上昇したときに開裂させられてその内圧を解放する弁動作を行う。 The fracture induced Article 31, for example to form an annular line pattern as shown in the figure, performs a valve operation to release the internal pressure thereof is cleaved when the internal pressure of the container 2 rises abnormally. これにより内圧の異常上昇による外形容器2の爆発的破裂が防止されるようになっている。 Thereby so explosive rupture of outer container 2 due to an abnormal increase in the internal pressure is prevented.

【0022】上記突起端子部23が形成された閉塞端面部21には、円盤状の保護部材4が嵌着させられている。 [0022] the projection terminal portion 23 closed end surface portion 21 which is formed in a disk-shaped protective member 4 is allowed to fit. この保護部材4は電気絶縁性で非クッション性の剛性材質、たとえばPP(ポリプロピレン)やPE(ポリエチレン)などを用いて構成され、その全体は、閉塞端面部21全体を覆うキャップ状に形成されているこの保護部材4には、上記防爆安全弁3よりも外側で上記閉塞端面部21の縁に沿った環状部分に着座する環状脚部4 The protection member 4 is formed by using a non-cushioning rigid material with an electrically insulating, for example PP etc. (polypropylene) or PE (polyethylene), the whole is formed into a cap shape that covers the entire closed end surface portion 21 the protective member 4 are, annular leg 4 to be seated in an annular portion along the edge of the closed end surface portion 21 on the outside than the explosion-proof safety valve 3
1と、この環状脚部41に支持されて上記防爆安全弁3 1, the explosion-proof safety valve 3 is supported on the annular leg 41
を覆うとともに上記突起端子部23よりも若干高い位置に防護面43を形成する防護蓋部42とが一体に形成されている。 A protective lid 42 to form the protective surface 43 to a position slightly higher than the projecting terminal portion 23 is formed integrally with the cover.

【0023】上記保護部材4は、突起端子部23が落下等によって受ける衝撃を上記防護面43にて受け止める。 [0023] The protective member 4 receives the impact projecting terminal portion 23 is received by a drop or the like in the protective surface 43. この防護面43にて受け止めた衝撃は上記環状脚部41に伝達される。 Impact was received by the protective surface 43 is transmitted to the annular leg 41. 環状脚部41は、上述したように、 Annular leg 41, as described above,
上記防爆安全弁3よりも外側で上記閉塞端面部の21縁に沿った環状部分に着座して上記防護蓋部42を支持しているので、上記防護面43が受け止めた衝撃は、形状構造的に高強度となっている筒状外形容器2の筒部軸方向に伝達される。 Since seated on the annular portion along the 21 edges of the closed end face at the outer side than the explosion-proof safety valve 3 supporting the protective cover 42, the impact which the protection surface 43 is received, the shape structurally is transmitted to the cylindrical portion axial direction of the cylindrical outer container 2 has a high strength.

【0024】これにより、上記保護部材4が嵌着された電池は、図2に示すように、突起端子部23側が直撃されるような状態で落下させられても、強度的な弱点となっている防爆安全弁はその落下の衝撃から保護される。 [0024] Thus, a battery in which the protective member 4 is fitted, as shown in FIG. 2, also be dropped in a state that side protruding terminal portion 23 is hit by a strength weakness explosion-proof safety valve there is protected from the impact of the fall.

【0025】この衝撃の伝達による保護作用は、保護部材4が非クッション性の剛性材質で構成されていることにより、その保護部材4が形成する上記防護面43を上記突起端子部23と同じかそれよりもわずかに高い位置に形成することで達成される。 The protective effect of the transmission of the impact, by the protection member 4 is formed from a rigid material for the non-cushioning, the same or the protective surface 43 of the protective member 4 is formed with the projecting terminal portion 23 it is achieved by forming a slightly higher position than. したがって、上記保護部材4は外形容器2の筒長すなわち電池1の外形サイズをほとんど増大させることなく、その電池1の耐衝撃性を確実に高めることができる。 Therefore, the protective member 4 without increasing little external size of the cylindrical length i.e. cell 1 external container 2 can be improved surely the impact resistance of the battery 1.

【0026】このように、上述した電池1では、その外形サイズあるいは包装サイズを増大させることなく、たとえば複数本を束ねた包装状態での落下等に対して十分な耐衝撃性を備えることができる。 [0026] Thus, the battery 1 described above, without increasing the outer size or pack sizes can be provided with sufficient impact resistance against e.g. drop or the like in a packaging state of bundling a plurality .

【0027】上記保護部材4は、落下以外の機械的衝撃やストレスからの保護にも有効である。 [0027] The protective member 4 is also effective to protect against mechanical shock and stress than falling. たとえば、電池の製造工程において、突起端子部23と防爆安全弁3が形成された閉塞端面部21に上記保護部材4を嵌着させることにより、その工程中に加わる機械的衝撃やストレスから上記安全弁3を保護することができる。 For example, in the manufacturing process of the battery, by fitting the protective member 4 to the closed end surface portion 21 projecting terminal portion 23 and the explosion-proof safety valve 3 is formed, the safety valve 3 from mechanical shock or stress applied during the process it is possible to protect the. 工程中に保護部材4が取り付けられた電池1は、その保護部材4 Battery 1 protected during the process member 4 is mounted, the protective member 4
を残したままの状態で最終完成製品とすることができる。 It is possible to the final finished product in a state in which left. したがって、工程後に保護部材を取り外すという手間は生じない。 Therefore, there is no trouble of after step removing the protective member.

【0028】また、上記保護部材4は電気絶縁性なので、その保護部材4が閉塞端面部21全体を覆うキャップ状に形成されていれば、未使用時での不意の短絡や放電を防止する機能を得ることができる。 Further, since the protective member 4 is electrically insulative, if the protective member 4 is formed in a cap-shaped covering the entire closed end surface portion 21, functions to prevent short-circuiting and discharge unexpected in Unused it is possible to obtain. これとともに、 At the same time,
その保護部材4の嵌着の有無によって電池の新品/使用済みを個別に識別する目安としての機能も得ることができる。 The presence or absence of fitted and the protective member 4 can be obtained also functions as a guide to identify individual new / used batteries. なお、短絡や放電の防止機能は、上記保護部材4 Incidentally, the prevention of short circuit or discharge function, the protective member 4
の少なくとも表面部を電気絶縁性にすることで得ることができる。 At least the surface portion of the can be obtained by electrical insulation. したがって、上記保護部材4は表面に絶縁処理を施した金属製であってもよい。 Therefore, the protective member 4 may be made of a metal subjected to insulating treatment on the surface.

【0029】図3はこの発明による筒形密閉電池の別の実施形態を示す。 [0029] Figure 3 illustrates another embodiment of a cylindrical sealed battery according to the present invention.

【0030】上述した実施形態との相違点に着目して説明すると、同図に示す筒形密閉電池1では、上記保護部材4が突起端子部23の上方を開放するリング状に形成されるとともに、そのリングの上側端面に上記突起端子部23とほぼ同じ高さの環状防護面43を形成している。 [0030] is described by focusing on the difference from the embodiment described above, the cylindrical sealed battery 1 shown in the figure, together with the protective member 4 is formed in a ring shape which opens upward of the projection terminal portion 23 forms an annular protective surface 43 of substantially the same height as the said projecting terminal portions 23 on the upper end surface of the ring.

【0031】この保護部材4が嵌着された電池1も、図4に示すように、突起端子部23側が直撃されるような状態で落下させられたときに、その落下衝撃を形状構造的に高強度となっている筒状外形容器2の筒部軸方向に伝達して、強度的な弱点となっている防爆安全弁3の破壊を防止することができる。 The cell 1 the protective member 4 is fitted also, as shown in FIG. 4, when the side projection terminal portion 23 has been dropped in the state as hit, the drop impact shape structurally is transmitted to the cylindrical outer container 2 of the cylindrical portion axial direction which is a high strength, it is possible to prevent destruction of the explosion-proof safety valve 3 which is a strength weakness.

【0032】さらに、上記リング状の保護部材4が嵌着された電池1は、その保護部材4を嵌着させた防護状態のままで電池端子への電気接続を行うことができる。 Furthermore, the battery 1 in which the ring-shaped protective member 4 is fitted, it is possible to perform electrical connection to the battery terminals while protection state of being fitted to the protective member 4. このことは、たとえば製造工程での測定や検査、使用前の電圧チェックなどに好都合である。 This is, for example, measuring and inspection in the manufacturing process, it is convenient, such as on the voltage check before use.

【0033】図5は、この発明による電池包装体の実施形態を示す。 [0033] Figure 5 shows an embodiment of a battery package according to the present invention.

【0034】同図において、(A)は図1に示した電池1の包装体10を、(B)は図3に示した電池1の包装体10をそれぞれ示す。 [0034] In the figure illustrates (A), respectively the package 10 of the battery 1 shown in FIG. 1, (B) is a package 10 of the battery 1 shown in FIG. 同図の(A)および(B)にそれぞれ示すように、保護部材4が嵌着された電池1は、 As shown respectively in the figure (A) and (B), battery 1 protective member 4 is fitted, the
透明熱収縮フィルムなどの包装材51によって複数本(8本)ずつまとめて包装された形(パッケージ)で流通市場へ出荷される。 It is shipped to market in the transparent heat shrinkable plurality (eight) by packaging material 51, such as a film by collectively packaged form (package).

【0035】この包装体10を運送途中などで誤って落下させると、前述したように、その中の1本だけに包装体10の総重量による落下衝撃が加わることがあるが、 [0035] Dropping incorrectly in such way transportation the package 10, as described above, it is possible to drop impact is applied due to the total weight of the package 10 only to one of them,
このような場合でも、上記保護部材4がその落下衝撃を形状構造的に高強度となっている筒状外形容器の筒部軸方向に伝達させることにより、構造的に弱点となっている防爆安全弁3の破壊を確実に防ぐことができる。 Even in this case, by transmitting to the tubular portion axis direction of the cylindrical outer container the protective member 4 has become the drop impact shape structurally high strength, explosion-proof safety valve has a structurally weak 3 destruction of can be reliably prevented.
