Description

本発明は、二次電池を充電状態にして販売することを可能にする二次電池包装体に関するものである。   The present invention relates to a secondary battery package that enables a secondary battery to be sold in a charged state.

二次電池の中でもニッケル水素蓄電池やニッケルカドミウム蓄電池は自己放電率が大きく、保管期間や販売期間が長くなると放電可能容量の低下が避けられない。また、リチウム二次電池は自己放電率は小さいものの、満充電状態での保管は電池の劣化をまねきやすいので、５０％以下の充電量にして販売される。   Among secondary batteries, nickel metal hydride storage batteries and nickel cadmium storage batteries have a high self-discharge rate, and a decrease in dischargeable capacity is inevitable when the storage period and the sales period become long. In addition, although the lithium secondary battery has a small self-discharge rate, storage in a fully charged state is likely to cause deterioration of the battery, and is sold at a charge amount of 50% or less.

従って、ユーザは二次電池を購入すると、まず充電を行った後に所要の機器に装填する手間を要することになり、乾電池のように購入した電池を即座に機器に装填して使用できる状態とはならない課題があった。ニッケル水素蓄電池のように出力電圧が乾電池の出力電圧と近く、寸法形状が乾電池と同等のものでは、乾電池との互換性を得ることができ、乾電池のように使い捨てでなく、繰り返し使用できる経済性を得ることが可能となる。そのためには、ユーザは購入後に充電を行うことなく即座に使用できるような放電可能容量が充分にある状態で販売することが要求される。   Therefore, when a user purchases a secondary battery, it first takes time to charge the device after charging, and the state where the purchased battery such as a dry battery can be immediately loaded into the device and used. There was a problem that was not possible. If the output voltage is close to the output voltage of the dry cell, such as a nickel metal hydride battery, and the dimensions are the same as the dry cell, compatibility with the dry cell can be obtained, and it is not disposable like the dry cell. Can be obtained. For this purpose, the user is required to sell in a state where there is sufficient dischargeable capacity that can be used immediately without charging after purchase.

ニッケル水素蓄電池においては、満充電まで充電して出荷されたときから１年経過後でも８０％前後の放電可能容量に維持できるものが開発されているが、同一サイズでの容量が少なくなる課題があり、出荷時から実使用時までの経過時間を管理する手間を要する。   Nickel-metal hydride storage batteries have been developed that can be maintained at a dischargeable capacity of around 80% even after one year has passed since they were fully charged and shipped, but there is a problem that the capacity of the same size is reduced. Yes, it takes time and effort to manage the elapsed time from shipping to actual use.

ユーザが必要とするときに充分な放電可能容量がある二次電池を購入することが理想であるが、現実には前述のような理由から即座に使用できる二次電池を確実にユーザに届けることは困難な状態にある。   It is ideal to purchase a secondary battery that has sufficient dischargeable capacity when the user needs it. In reality, however, a secondary battery that can be used immediately is surely delivered to the user for the reasons described above. Is in a difficult state.

充電されて放電可能容量が充分にある二次電池をユーザが購入できるようにするには、販売拠点において充電して販売することが考えられるが、包装体を破壊することなく二次電池に充電するには、非接触で充電電力を二次電池に供給する構成が必要となる。電気髭剃り器や電動歯ブラシなどのように機器に組み込まれた二次電池に対し、電磁誘導により非接触で充電電力を供給する電磁誘導充電方式は広く知られている（特許文献１参照）。この場合では機器及び充電器に電磁誘導による電力伝送の構成が設けられている。   To make it possible for users to purchase a secondary battery that has been charged and has sufficient dischargeable capacity, it is possible to charge and sell it at a sales base, but the secondary battery can be charged without destroying the package. In order to achieve this, a configuration for supplying charging power to the secondary battery in a non-contact manner is required. 2. Description of the Related Art An electromagnetic induction charging method that supplies charging power to a secondary battery incorporated in a device such as an electric shaver or an electric toothbrush by electromagnetic contact is widely known (see Patent Document 1). In this case, the device and the charger are provided with a power transmission configuration by electromagnetic induction.

二次電池そのものに充電するには、二次電池の正極及び負極に充電回路を電気的接続する必要があり、二次電池の外周に電磁誘導二次コイルを巻き付けると共に、電磁誘導二次コイルに誘起した起電力を二次電池の充電電力として供給する充電回路を設けた特殊な二次電池として構成されたものが知られている（特許文献２及び特許文献３参照）。この電磁結合による充電構造を備えた二次電池は、電磁誘導一次コイルを備えた専用の充電器に投入することにより電磁誘導により誘起した起電力によって二次電池を充電することができる。
特開平１１−０６９６３９号公報 特開２００５−１２４３２４号公報 特開２００５−１１７７４８号公報 In order to charge the secondary battery itself, it is necessary to electrically connect a charging circuit to the positive and negative electrodes of the secondary battery, and an electromagnetic induction secondary coil is wound around the outer periphery of the secondary battery, and the electromagnetic induction secondary coil is A battery that is configured as a special secondary battery provided with a charging circuit that supplies an induced electromotive force as charging power for the secondary battery is known (see Patent Document 2 and Patent Document 3). The secondary battery provided with the charging structure by electromagnetic coupling can be charged by the electromotive force induced by electromagnetic induction by putting it in a dedicated charger provided with an electromagnetic induction primary coil.
Japanese Patent Application Laid-Open No. 11-069639 JP 2005-124324 A JP 2005-117748 A

従来技術として示した電気髭剃り器などのように機器に組み込まれた二次電池を充電器と電磁結合することによって充電する構成は、二次電池を電源とする携帯電子機器の種類や数が増加するのに伴って携帯電話機やモバイルコンピュータなどにも適用範囲が増加するものと考えられる。しかし、本発明が目的とする二次電池そのものを購入後直ぐに使用できる状態に充電された状態で販売するものではない。   The configuration in which the secondary battery built into the device, such as the electric shaver shown as the prior art, is charged by electromagnetically coupling with the charger is the type and number of portable electronic devices that use the secondary battery as a power source. As the number increases, the scope of application is expected to increase for mobile phones and mobile computers. However, the secondary battery itself intended by the present invention is not sold in a state where it is charged in a state where it can be used immediately after purchase.

また、従来技術として示した二次電池そのものに充電機能を設けた構成は、二次電池が規格に沿ったものでなく、特殊なものとなるため汎用性がなく、充電機能を設けているために二次電池としての体積減少は避けられず、体積エネルギー密度の小さい二次電池となってしまう問題がある。この特殊な二次電池の場合も、二次電池を購入後直ぐに使用できる状態に充電された状態で販売できるようにする本発明の目的を叶えるものではない。   In addition, the configuration provided with a charging function in the secondary battery itself shown as the prior art is not versatile and has a charging function because the secondary battery does not conform to the standard and is special. However, a decrease in volume as a secondary battery is unavoidable, resulting in a secondary battery having a small volumetric energy density. Even in the case of this special secondary battery, the object of the present invention is not fulfilled so that the secondary battery can be sold in a state where it can be used immediately after purchase.

本発明が目的とするところは、一般市販する汎用性のある二次電池を購入後に直ちに機器に装填して使用できるようにした二次電池包装体を提供することにある。   An object of the present invention is to provide a secondary battery package in which a general-purpose secondary battery, which is commercially available, can be used by being immediately loaded into a device after purchase.

上記目的を達成するための本発明に係る二次電池包装体は、二次電池を被覆包装する包装体に、二次電池と、電磁波受信用の受信アンテナと、外部に配設された送信アンテナから出力された電磁波により受信アンテナに誘起した起電力を前記二次電池に供給する所定電力に変換する充電電力生成回路とを備えた充電手段が収容されてなることを特徴とする。   In order to achieve the above object, a secondary battery packaging body according to the present invention includes a secondary battery, a receiving antenna for receiving electromagnetic waves, and a transmitting antenna disposed outside in a packaging body for covering and packaging the secondary battery. And a charging power generation circuit for converting an electromotive force induced in the receiving antenna by the electromagnetic wave output from the power into a predetermined power to be supplied to the secondary battery.

上記構成によれば、二次電池を販売用に被覆包装した二次電池包装体の販売場所あるいは保管場所において、それに接近させて電磁波を出力する非接触電力伝送手段を配し、送信アンテナから電磁波を発生させると、二次電池包装体に設けた受信アンテナに起電力が誘起するので、この起電力を充電電力生成回路により充電電力に変換して二次電池に印加すると二次電池は充電される。二次電池に充電する充電電力は、ニッケル水素蓄電池などのように自己放電率が大きい二次電池においては、自己放電を補う程度の小さい充電電力でよく、二次電池包装体に設ける充電機能は簡易に構成することができる。   According to the above configuration, in the sales place or storage place of the secondary battery package in which the secondary battery is coated and sold for sale, the non-contact power transmission means for outputting the electromagnetic wave in close proximity thereto is arranged, and the electromagnetic wave is transmitted from the transmitting antenna. When an electromotive force is generated, an electromotive force is induced in the receiving antenna provided in the secondary battery packaging body. Therefore, when the electromotive force is converted into charging power by the charging power generation circuit and applied to the secondary battery, the secondary battery is charged. The The charging power for charging the secondary battery may be a small charging power to compensate for the self-discharge in the secondary battery having a large self-discharge rate such as a nickel metal hydride storage battery. It can be configured simply.

上記構成において、包装体はブリスターパックに構成したとき、その台紙上に充電手段を構成することにより、二次電池だけのブリスターパックと同等の包装形態に構成することができるので、販売に制約を受けることがない。   In the above configuration, when the package is configured as a blister pack, by configuring charging means on the mount, it can be configured in a packaging form equivalent to a blister pack with only a secondary battery, so there are restrictions on sales. I will not receive it.

また、包装体はブリスターパックに構成したとき、透明カップ内に二次電池と共に充電手段を収容することにより、二次電池と充電手段との間の電気的接続が容易であり、充電手段を回収して再使用することも可能となる。   In addition, when the package is configured as a blister pack, the charging means is accommodated together with the secondary battery in the transparent cup, so that the electrical connection between the secondary battery and the charging means is easy, and the charging means is recovered. It can also be reused.

また、二次電池と、それに接続した充電手段とを一体化したものを包装体で被覆包装することにより、電気的接続に好適な状態が得られると共に、組立及び包装作業を簡易に実施することができる。   Also, by covering and packaging the secondary battery and the charging means connected thereto with a packaging body, a state suitable for electrical connection can be obtained, and assembly and packaging operations can be easily performed. Can do.

また、充電手段は構成要素を容器内に一体化した充電パックに形成され、この充電パックと二次電池とを接続ホルダにより保持すると共に電気的接続して包装体で被覆包装することにより、二次電池と充電パックとを簡易に一体化することができ、包装作業の作業性が容易となる。   In addition, the charging means is formed in a charging pack in which components are integrated in a container, and the charging pack and the secondary battery are held by a connection holder and electrically connected to cover and wrap with a package. The secondary battery and the charge pack can be easily integrated, and the operability of the packaging work becomes easy.

また、充電手段は、包装体と着脱可能に設けることができ、ユーザが購入した時点で充電手段を包装体から取り外すことにより再使用が可能となり、二次電池を充電する機能を設けたことによるコストアップを抑えることができ、充電手段の再使用が可能となる。   Further, the charging means can be provided so as to be detachable from the packaging body, and can be reused by removing the charging means from the packaging body at the time of purchase by the user, thereby providing a function of charging the secondary battery. An increase in cost can be suppressed, and the charging means can be reused.

上記充電手段と包装体との間の着脱は、専用治具を用いて行うことにより、ユーザの購入時点までに充電手段が取り外されることを防止することができる。   The attachment and detachment between the charging means and the package can be performed by using a dedicated jig, thereby preventing the charging means from being removed by the time of purchase by the user.

本発明によれば、自己放電率が大きい二次電池などを、その保管場所や販売場所において徐々に充電してユーザが購入した時点で使用可能な充電量にすることができるので、ユーザは充電を行うことなく購入後に直ちに使用できる乾電池的な使用を可能にする。また、被覆包装された二次電池に対して非接触で包装を破損させることなく充電が可能となる。   According to the present invention, a secondary battery or the like having a high self-discharge rate can be gradually charged at a storage location or a sales location to obtain a charge amount usable at the time of purchase by the user. Enables the use of dry batteries that can be used immediately after purchase. In addition, charging can be performed without damaging the packaging in a non-contact manner with respect to the coated and packaged secondary battery.

本実施形態は、二次電池の一例であるニッケル水素蓄電池を販売するための二次電池包装体について説明するが、規格、包装形態などが異なる他の二次電池についても同様に構成できることは言うまでもない。   Although this embodiment demonstrates the secondary battery package for selling the nickel hydride storage battery which is an example of a secondary battery, it cannot be overemphasized that other secondary batteries from which a specification, a packaging form, etc. differ can be constituted similarly. Yes.

ニッケル水素蓄電池は、ニッケルカドミウム蓄電池に比してエネルギー密度が高く、ＥＵ（欧州連合）における化学物質規制（ＲｏＨＳ指令など）の対象となる材料を使用していないので適用範囲が広く、リチウム二次電池のように過充電や過放電を防止するための保護回路を設ける必要がないので汎用二次電池として好適なものである。また、出力電圧（公称電圧）が１.２Ｖで乾電池の出力電圧に近く、寸法形状が乾電池と同等に構成されているので、乾電池との互換性を得ることができ、充電により繰り返し使用できる経済性も備えている。このような乾電池的な使途を得るためにも、ニッケル水素蓄電池の特性である自己放電率が大きい課題を解決することが要求される。即ち、購入して充電することなく、直ぐに機器に装填して使用できるようにすることが望まれている。   Nickel metal hydride storage batteries have a higher energy density than nickel cadmium storage batteries and do not use materials subject to EU (European Union) chemical substance regulations (such as the RoHS directive). Since it is not necessary to provide a protection circuit for preventing overcharge and overdischarge unlike a battery, it is suitable as a general-purpose secondary battery. In addition, the output voltage (nominal voltage) is 1.2V, which is close to the output voltage of a dry cell, and has the same size and shape as the dry cell, so that compatibility with the dry cell can be obtained, and it can be used repeatedly by charging. It also has sex. In order to obtain such a use as a dry battery, it is required to solve the problem of a high self-discharge rate, which is a characteristic of a nickel metal hydride storage battery. That is, it is desired that the device can be immediately loaded and used without being purchased and charged.

本実施形態では、ユーザはニッケル水素蓄電池を購入したとき、従来のように充電した後に機器に装填する手間をかけるのではなく、購入時点で充分な放電可能容量がある充電状態にして販売できるようにする二次電池包装体を構成する。   In this embodiment, when a user purchases a nickel-metal hydride storage battery, the user can sell it in a charged state with sufficient dischargeable capacity at the time of purchase, rather than taking the trouble of charging the device after charging it as in the past. A secondary battery package is formed.

図１（ａ）（ｂ）は、第１の実施形態に係る二次電池包装体１の構成を示すもので、２本のＡＡサイズのニッケル水素蓄電池５，５をブリスターパックの包装形態に被覆包装した例を示している。図１（ｂ）に示すように、ブリスターパックを形成する台紙６上には、２本のニッケル水素蓄電池５，５に電気的に接続する端子金具１１，１２，１３と、アンテナコイル７と、このアンテナコイル７に誘起した起電力を充電電力に変換する充電電力生成回路を構成するコンデンサ４０及び整流ダイオード４１とが設けられている。前記端子金具１１，１２，１３に２本のニッケル水素蓄電池５，５を装填することにより、２本のニッケル水素蓄電池５，５は直列接続され、図４に示すような充電回路が形成される。   FIGS. 1A and 1B show the configuration of the secondary battery packaging 1 according to the first embodiment, in which two AA-sized nickel-metal hydride storage batteries 5 and 5 are covered in a blister pack packaging form. An example of packaging is shown. As shown in FIG.1 (b), on the mount 6 which forms a blister pack, the terminal metal fittings 11, 12, and 13 electrically connected to the two nickel metal hydride storage batteries 5 and 5, the antenna coil 7, A capacitor 40 and a rectifier diode 41 constituting a charging power generation circuit that converts the electromotive force induced in the antenna coil 7 into charging power are provided. By loading the two nickel metal hydride storage batteries 5 and 5 into the terminal fittings 11, 12 and 13, the two nickel metal hydride storage batteries 5 and 5 are connected in series to form a charging circuit as shown in FIG. 4. .

台紙６上に配置されたニッケル水素蓄電池５，５及び充電回路の構成要素は、図１（ａ）に示すように、透明樹脂によって形成された透明カップ１４で被覆され、透明カップ１４の周縁部を台紙６に溶着することにより二次電池包装体１に仕上げられる。アンテナコイル３９及びコンデンサ４０、整流ダイオード４１を配線接続する導体パターンは、台紙６の表面に形成された樹脂被覆層の上に圧着形成され、アンテナコイル３９の表面は透明カップ１４の台紙６への貼着面によって被覆される。   As shown in FIG. 1A, the components of the nickel hydride storage batteries 5 and 5 and the charging circuit arranged on the mount 6 are covered with a transparent cup 14 formed of a transparent resin, and the peripheral portion of the transparent cup 14 Is welded to the mount 6 to finish the secondary battery package 1. A conductor pattern for wiring connection of the antenna coil 39, the capacitor 40, and the rectifier diode 41 is formed on the resin coating layer formed on the surface of the mount 6, and the surface of the antenna coil 39 is connected to the mount 6 of the transparent cup 14. Covered by the sticking surface.

この二次電池包装体１は、製造されて複数個をダンボール梱包して販売拠点に向けて出荷されるまでの保管場所、あるいは販売拠点において陳列販売される販売場所に設けられた非接触電力伝送装置が備える送信アンテナから出力される電磁波をアンテナコイル３９で受信することにより非接触で充電電力を得て、ニッケル水素蓄電池５，５に充電電力を供給する。   This secondary battery package 1 is a non-contact power transmission provided in a storage place where a plurality of the battery packs are manufactured and packed in a cardboard box and shipped to a sales base, or in a sales place displayed and sold at the sales base. Charging power is obtained in a non-contact manner by receiving electromagnetic waves output from a transmission antenna included in the apparatus by the antenna coil 39, and charging power is supplied to the nickel metal hydride storage batteries 5 and 5.

前記非接触電力伝送装置は、電波法の規制を受けない周波数例えば、１３５ｋＨｚ以下の微弱無線局、非接触ＩＣカードに用いられる１３.５６ＭＨｚ、アマチュア無線の４３０〜４３３ＭＨｚ、携帯電話の０.８ＧＨｚ、１.４ＧＨｚ、１.９ＧＨｚ〜２.１ＧＨｚ、無線ランやブルートゥースの２.４５ＧＨｚ等の商用電波及び空中線電力の電磁波を二次電池包装体１の近接位置から出力するので、アンテナコイル３９及びコンデンサ４０による共振回路を非接触電力伝送装置が出力する電磁波の周波数に同調させると、共振回路に誘起起電力が発生する。共振により発生した交流電流は整流ダイオード４１で整流されてニッケル水素蓄電池５，５に充電電力として供給される。   The non-contact power transmission device has a frequency not subject to regulations of the Radio Law, for example, a weak radio station of 135 kHz or less, 13.56 MHz used for a non-contact IC card, 430-433 MHz for amateur radio, 0.8 GHz for a mobile phone, Since an electromagnetic wave of 1.4 GHz, 1.9 GHz to 2.1 GHz, radio wave or Bluetooth 2.45 GHz or other commercial radio wave and antenna power is output from the proximity position of the secondary battery package 1, the antenna coil 39 and the capacitor 40 are output. When the resonant circuit according to is tuned to the frequency of the electromagnetic wave output by the non-contact power transmission device, an induced electromotive force is generated in the resonant circuit. The alternating current generated by the resonance is rectified by the rectifier diode 41 and supplied to the nickel hydride storage batteries 5 and 5 as charging power.

本構成における充電は一般的な充電と異なり、微小な充電電流で徐々にニッケル水素蓄電池５，５の自己放電を補う程度の充電を実施することで足りる。ここではニッケル水素蓄電池５，５を直列接続しているので、整流ダイオード４１から出力される充電電圧は、ニッケル水素蓄電池５，５に微小な充電方向の電流が流れる程度、例えば１.３〜１.５Ｖ／セルでよく、充電により電圧上昇したニッケル水素蓄電池５，５の正極、負極間の電圧が充電電圧と同一になったとき充電は停止される。前記整流ダイオード４１はニッケル水素蓄電池５，５に充電方向に充電電流を流すと共に、ニッケル水素蓄電池５，５から放電方向に電流が流れることを阻止する逆流防止の役割も担っている。   The charging in this configuration is different from the general charging, and it is sufficient to carry out the charging to compensate for the self-discharge of the nickel metal hydride storage batteries 5 and 5 with a small charging current. Here, since the nickel hydride storage batteries 5 and 5 are connected in series, the charging voltage output from the rectifier diode 41 is such that a small amount of current flows in the nickel hydride storage batteries 5 and 5, for example, 1.3 to 1 The charge is stopped when the voltage between the positive electrode and the negative electrode of the nickel-metal hydride batteries 5 and 5 whose voltage has increased due to charging becomes equal to the charging voltage. The rectifier diode 41 has a role of preventing a backflow that prevents a current from flowing in the discharge direction from the nickel metal hydride storage batteries 5, 5 while flowing a charge current in the charge direction to the nickel metal hydride storage batteries 5, 5.

本実施形態においては、２本のニッケル水素蓄電池５，５を直列接続しているが、これは配線接続の簡略化を図ったためで、これに限定されるものではなく、並列接続であってもよい。   In the present embodiment, two nickel metal hydride storage batteries 5 and 5 are connected in series, but this is because the wiring connection is simplified, and is not limited to this. Good.

図２は、第２の実施形態に係る二次電池包装体２の構成を示すもので、端子金具１１，１２，１３、アンテナコイル３９、コンデンサ４０、整流ダイオード４１を絶縁シート（配線基板）４４上に固定することにより配線接続がなされ、端子金具１１，１２，１３に２本のニッケル水素蓄電池５，５を装填することにより、被包装物の全てが絶縁シート４４上に構成されるようにしている。この被包装物を搭載した絶縁シート４４を台紙６上に載置し、それを被覆して透明カップ１４を台紙６に溶着することにより、図１（ａ）に示した二次電池包装体１と同様外観の二次電池包装体２に仕上げることができる。また、ニッケル水素蓄電池を含む全ての構成要素が絶縁シート４４上に搭載されているので、ブリスターパックの形態だけでなく、箱状のパッケージなど多様な包装形態に自在に対応させることができる。   FIG. 2 shows the configuration of the secondary battery packaging body 2 according to the second embodiment. The terminal fittings 11, 12, 13, the antenna coil 39, the capacitor 40, and the rectifier diode 41 are combined with an insulating sheet (wiring board) 44. Wiring connection is made by fixing it on the top, and two nickel metal hydride storage batteries 5 and 5 are loaded on the terminal fittings 11, 12, 13, so that all the items to be packaged are configured on the insulating sheet 44. ing. The insulating sheet 44 on which the package is mounted is placed on the mount 6, covered therewith, and the transparent cup 14 is welded to the mount 6, whereby the secondary battery package 1 shown in FIG. The secondary battery packaging body 2 having the same appearance can be finished. Moreover, since all the components including the nickel-metal hydride storage battery are mounted on the insulating sheet 44, it is possible to freely support various packaging forms such as a box-shaped package as well as a blister pack form.

前記絶縁シート４４は、プリント配線基板として構成することが好ましく、図３に示すように、絶縁シート４４の裏面にアンテナコイル３９を渦巻き状の導体パターンに形成し、表面に形成した導体パターンのランド上に端子金具１１，１２，１３、コンデンサ４０、整流ダイオード４１を半田付けあるいは鋲止めし、表裏の導体パターンを接続することにより、ニッケル水素蓄電池５，５に接続して充電回路が構成される。   The insulating sheet 44 is preferably configured as a printed circuit board. As shown in FIG. 3, the antenna coil 39 is formed in a spiral conductor pattern on the back surface of the insulating sheet 44, and the land of the conductor pattern formed on the surface is formed. Soldering or soldering the terminal fittings 11, 12, 13, capacitor 40, rectifier diode 41 and connecting the front and back conductor patterns to connect to the nickel metal hydride storage batteries 5, 5 constitutes a charging circuit. .

この構成では、台紙６とは別の絶縁シート４４上に電気回路構成を搭載するので、電気絶縁性が確実に得られる絶縁シート４４の材料を選択することができると共に、ブリスターパックによる包装作業の作業性を向上させることができる。   In this configuration, since the electric circuit configuration is mounted on the insulating sheet 44 different from the mount 6, it is possible to select the material of the insulating sheet 44 with which electrical insulation can be obtained with certainty, and for the packaging work by the blister pack. Workability can be improved.

上記第１及び第２の各実施形態では、充電された状態のニッケル水素蓄電池５，５を販売できるものの、充電回路を同梱することによるコストアップは避けられない。そこでコストアップを抑えるために、充電回路部分は包装体から分離可能とし、ユーザが購入した時点で充電回路部分を回収して再使用できるものとする構成について説明する。   In each of the first and second embodiments, the nickel hydride storage batteries 5 and 5 in a charged state can be sold, but an increase in cost due to the inclusion of the charging circuit is inevitable. Therefore, in order to suppress an increase in cost, a configuration will be described in which the charging circuit portion is separable from the package, and the charging circuit portion can be collected and reused when purchased by the user.

図３（ａ）は、第３の実施形態に係る二次電池包装体３の構成を示すもので、２本のニッケル水素蓄電池５，５を包装したブリスターパック２１を構成する台紙６の一端に、充電回路を構成した充電パック３７が着脱可能に連結されている。   FIG. 3A shows a configuration of the secondary battery packaging body 3 according to the third embodiment, and is attached to one end of the mount 6 constituting the blister pack 21 in which the two nickel-metal hydride storage batteries 5 and 5 are packaged. The charging pack 37 constituting the charging circuit is detachably connected.

この充電パック２２は、２つ折り構造のカバーケース４２を閉じると、一端辺が薄く開口し、開口部分に正極接続片２８及び負極接続片２９が露出した状態になるので、正極接続片２８及び負極接続片２９をブリスターパック２１の接続片挿入部２６に差し込むと共に、開口部分にブリスターパック２１の端辺を挿入させると、ブリスターパック２１と充電パック３７とが連結されると同時に電気的接続がなされる。ブリスターパック２１と充電パック２２との連結間は、連結ロック３０により連結解除できないようにロックし、ユーザが購入して代金清算時に専用治具により連結を解除してブリスターパック２１から充電パック３７を取り外すようにすることが望ましい。   When the charging pack 22 is closed, the cover case 42 having a folded structure is closed, and one end of the charging pack 22 is opened thinly, and the positive electrode connecting piece 28 and the negative electrode connecting piece 29 are exposed in the opening portion. When the connecting piece 29 is inserted into the connecting piece insertion portion 26 of the blister pack 21 and the end side of the blister pack 21 is inserted into the opening, the blister pack 21 and the charging pack 37 are connected simultaneously and electrically connected. The The connection between the blister pack 21 and the charge pack 22 is locked by the connection lock 30 so that the connection cannot be released. When the user purchases and pays for the price, the connection is released by a dedicated jig and the charge pack 37 is removed from the blister pack 21. It is desirable to remove it.

販売拠点では充電パック３７を回収して再使用できるようにすることにより、充電回路付きの包装体に構成することによるコストアップを抑えることができ、ブリスターパック２１と充電パック３７との連結をロックすることにより、盗難や悪戯などによってブリスターパック２１と充電パック３７とが分離されてしまうことを防止することができる。   By collecting and reusing the charging pack 37 at the sales base, it is possible to suppress an increase in cost due to the construction of a packaging body with a charging circuit, and the connection between the blister pack 21 and the charging pack 37 is locked. By doing so, it is possible to prevent the blister pack 21 and the charge pack 37 from being separated due to theft or mischief.

図５（ａ）は、第４の実施形態に係る二次電池包装体４の構成を示すもので、ブリスターパックを構成する透明カップ１４内に２本のニッケル水素蓄電池５，５と充電パック４６とを収容している。   FIG. 5A shows the configuration of the secondary battery package 4 according to the fourth embodiment. In the transparent cup 14 constituting the blister pack, two nickel metal hydride storage batteries 5 and 5 and the charge pack 46 are shown. And is housed.

充電パック４６は、図２に示した充電回路の構成要素を容器内に収容し、容器の両端に接続片を外部露出させたもので、両端に設けた接続片間の距離はニッケル水素蓄電池５，５の高さ寸法と一致している。この充電パック４６と２本のニッケル水素蓄電池５，５を図５（ｃ）に示すように構成された接続ホルダ４５に収納すると、接続ホルダ４５の両内側面に設けた接続プレート４７によって互いに電気的接続がなされる。ここでは２本のニッケル水素蓄電池５，５は並列接続されて充電パック４６に接続される。   The charging pack 46 accommodates the components of the charging circuit shown in FIG. 2 in a container and externally exposes connection pieces at both ends of the container. The distance between the connection pieces provided at both ends is the nickel hydride storage battery 5. , 5 is consistent with the height dimension. When the charging pack 46 and the two nickel metal hydride storage batteries 5 and 5 are stored in the connection holder 45 configured as shown in FIG. 5C, the connection plates 47 provided on both inner surfaces of the connection holder 45 are electrically connected to each other.
