Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dry battery storage container, and more particularly to a dry battery storage container that can store dry batteries for a long period of time and is convenient to carry.

As is well known, dry batteries form internal polar cells during storage or in a resting state, and the so-called self-discharge phenomenon occurs in which the active material is consumed, regardless of the battery type. Since batteries are used by discharging them after being stored for a period of time, their storage stability is one of the important performance characteristics of batteries.

For this reason, dry batteries are generally stored under low temperature, low humidity environmental conditions in order to minimize performance deterioration.

By the way, in recent years, electrical appliances have rapidly become widespread in households, and dry cell batteries have been adopted in a relatively wide range of appliances due to their ease of use as a power source for these appliances, and various other types of batteries have also been provided. There is.

In addition, multiple batteries are used instead of a single battery to power electrical appliances such as radio receivers and mobile lights, and in light of disasters such as earthquakes and typhoons, it is important to compare dry batteries in each household. There is a great need to preserve it for a long period of time.

However, as mentioned above, the performance of dry batteries deteriorates significantly depending on the storage conditions, but in reality, it is not possible to ensure a low temperature, low humidity storage environment in each household for the purpose of storing batteries. Dry batteries covered with shrinkable tubes, etc., were stored as they were in boxes, etc.

Therefore, when a stored dry cell battery is taken out and used in the event of a disaster such as an earthquake, its performance deteriorates to the point that it cannot be used.

This invention was made in view of the above circumstances, and its purpose is to provide an emergency power source that will not deteriorate in performance unless the package is opened, and that can be used as an emergency power source in times of leisure, earthquakes, etc. when commercial power sources are unavailable. An object of the present invention is to provide an easily portable dry battery storage container that can be used at 50°C.

In order to achieve this object, the present invention provides a dry battery storage container in which a dry battery is stored in an openable airtight and liquid-tight container, and after replacing the space inside the container with an inert gas. It is characterized by being sealed.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

It should be noted that the same reference numerals are used to refer to or corresponding parts in each figure.

FIG. 1 shows an embodiment of a dry battery storage container according to the present invention.

The dry battery storage container shown in the figure is made of approximately cylindrical metal such as aluminum or iron plated with nickel, and a plurality of cylindrical dry batteries 12 are electrically insulated in an airtight and liquid-tight container 10. The container 10 is housed in a multi-tiered manner with plastic sheet materials 14 disposed at the upper and lower ends, and the space inside the container 10 is sealed after being replaced with an inert gas.

A handle piece 16 with a ring portion is provided on the end surface of the container 10.
One end is riveted, and a V-groove 18 that goes around the edge is carved. When you pass your finger through the ring part of the handle piece 16 and pull it upward, the container 10 will be attached along the V-groove 18.
can be opened.

Further, the inner surface of the container 10 is made of, for example, polyethylene.
1, etc., or apply an electrically insulating film, in case the above-mentioned dry battery 12 stored inside
This is preferable because short circuit can be prevented if the electrode contacts the container 10.

In this embodiment, the dry battery 12 is a so-called AA battery or a AA battery.
．． Although AA type cylindrical batteries are shown as examples, it is of course possible to store button type batteries or a mixture of these batteries.

Examples of the inert gas include argon and helium.

These include rare gases such as neon, or gases with poor reactivity, such as nitrogen gas.

Now, the dry battery storage container having the above-mentioned configuration is as follows: container 10
Since the internal space is replaced with an inert gas and then sealed, the inert gas is chemically extremely stable even when the dry battery 12 is stored for a long period of time. Even if it occurs, it will not react with it, and it is possible to almost completely suppress the rapid deterioration of battery performance under high temperature and high humidity that occurs when stored in the air. can significantly improve the storage stability of

In addition, since multiple dry batteries 12 can be stored in the container 10, even in cases where commercial power supply is unavailable, such as during a REGISTO-9 earthquake,
Not only is it extremely convenient to carry as an emergency power source, but it can also be easily opened and used immediately.

2 and 3 show another unsealing structure of the dry battery storage container according to the present invention, which has substantially the same structure as the first embodiment above, except for the respective features shown below. .

First, the storage container shown in FIG. 2 has a handle piece 16 which has a ring portion on the end surface of the container 1o and a substantially rectangular through hole 2o at the tip.
' is removably attached, a tongue piece 22 is provided on the side of the container 10, and a through hole 20 of the handle piece 16- is provided.
By inserting the tongue piece 22 into the container and rolling it up one after another, the container can be opened as shown by the dotted line in the figure.

Moreover, the storage container shown in FIG. 3 has approximately T on the top surface of the container 1o.
A letter-shaped handle piece 16'' is removably attached, and one end of the container B1o is sealed by tightly fitting the lid 24. To open the container, insert the handle piece 16'' from the periphery of the container 1o. This is done by rotating this downward to disengage the lid 24 and the container 1o.

Even if the container 1o is configured as described above, the same effects as in the first embodiment can be achieved.

As described above, the dry battery storage container according to the present invention stores a dry battery in an openable air-tight and liquid-tight container, and seals the container after replacing the space inside the container with an inert gas. This is a storage container that can improve the storage life of dry batteries, is convenient to carry, and is easy to take out.
