Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button type battery provided with a structure for facilitating the work of mounting a small-sized battery to be mounted on a small device such as a hearing aid.

[0002]

2. Description of the Related Art Hearing aids are required to be small and lightweight, and to be worn by others so as not to be understood. Hearing aids include ear-hook type to be attached to the back of the ear, pocket type to attach the main body to a pocket, and frame-filling type to fill the frame of eyeglasses. The ceremony is becoming the mainstream. This ear canal type hearing aid has the advantages that it is not conspicuous to be worn, can be normally used for telephones, and can be worn while sleeping. Since the ear canal type is extremely miniaturized, its power source also needs to be miniaturized, and a battery having a diameter of 6 mm or less has been manufactured.

[0003]

Although the downsizing of batteries allows downsizing of devices such as hearing aids, the work of battery replacement becomes extremely difficult as the downsizing progresses. In particular, considering that the main target person who uses a hearing aid is the elderly, the work of putting a small battery in and out of a small mounting space must be said to be desperate. If the battery has a diameter of 6 mm or less, even a person who can perform a sound operation cannot freely handle it with his fingertips.

It is an object of the present invention to provide a button type battery provided with a means for assisting the work of loading an ultra-compact battery, which is difficult to handle even with a fingertip, into its mounting position.

[0005]

A button type battery according to a first invention of the present application for achieving the above object is a support surface extending from a holding surface formed to have a size that can be held by a fingertip. It is characterized in that a battery holding seal attached to an arbitrary surface is provided.

With the above arrangement, the holding surface of the battery holding seal can be held with the fingertips to suspend the battery, and the battery can be moved to its mounting position. The battery moved to the mounting position can be pushed into the mounting position by the fingertip, and a small battery that is difficult to handle with the fingertip can be loaded in the loading position in a small space.

The second invention of the present application is, in a button type battery configured as an air battery, extending from one end of a sealing surface adhered so as to seal the air intake formed on the positive electrode surface. A battery holding seal having a supporting surface attached to the side surface of the battery is provided.

According to the above construction, since the supporting surface extending from the sealing surface for sealing the air intake of the air battery is attached to the battery, the air battery is sealed from the battery when it is mounted on the device. After peeling off the surface to activate the air battery,
The battery to which the supporting surface is attached can be suspended by the peeled sealing surface and can be moved to the battery mounting position. The battery moved to the mounting position can be pushed into the mounting position with the fingertip, and a small air battery that is difficult to handle with the fingertip can be loaded into the loading position in a small space.

The battery-holding seal applied to the above-mentioned air battery is configured to extend outward from the battery in a direction opposite to the extending direction of the supporting surface from the sealing surface to form a knob portion, so that at the start of use. Not only is it easy to peel off the sealing surface from the battery from the knob, but the knob can be effectively used as a handle when suspending the battery on the support surface.

Further, the battery holding seal has a base film made of polypropylene, polyethylene or polyethylene terephthalate, and an adhesive material containing an acrylic acid ester polymer as a main component on the base film at an attachment site to the battery. Those coated with are suitable.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention.
The embodiments described below are examples of embodying the present invention and do not limit the technical scope of the present invention.

This embodiment shows a structure in which an ultra-small button type battery mainly used as a power source for hearing aids is easily handled. As a battery system of the button type battery, zinc is used as a negative electrode active material and positive electrode active material is used. It shows an example applied to a zinc-air battery using oxygen in the air as a substance.

Since the zinc-air battery uses oxygen in the air as a positive electrode active material, as shown in FIG.
The air intake 12 is open at 1. The air zinc inlet 10 is sealed by a seal during the storage period until the start of use of the zinc-air battery 10, and when the seal is peeled off during use, oxygen in the air is taken into the battery to start the battery reaction. , The battery voltage rises and the device is ready for use.

FIG. 1 shows the structure of a battery holding seal 1 according to this embodiment, which is a sealing surface 2 that is attached to a positive electrode case 11 of an air zinc battery 10 to seal an air intake 12. A support surface 3 attached to the side surface of the positive electrode case 11,
It becomes a handle when the sealing surface 2 is peeled off from the positive electrode case 11 at the start of use, and the supporting surface 3 holds the zinc-air battery 10
It is formed by providing a picking portion 4 which serves as a handle for suspending and supporting the. The battery holding seal 1 is made of polypropylene, polyethylene or polyethylene terephthalate film as a base material, and a pressure sensitive adhesive 7 containing an acrylic acid ester polymer as a main component is applied to the sealing surface 2 and the supporting surface 3 of the film. The seal is stamped into a shape as shown in FIG.

This battery holding seal 1 is shown in FIG.
As shown in (b), the sealing surface 2 is attached to the positive electrode case 11 so as to seal the air intake port 12, and the supporting surface 3 is attached to the side surface of the positive electrode case 11 to form the zinc-air battery 10. It is attached. As shown in FIG. 2, the zinc-air-air battery 10 is sold with the battery holding seal 1 attached, and when the user uses the zinc-air-air battery 10,
When the sealing surface 2 is peeled off from the positive electrode case 11 by holding the grip portion 4, the air intake 12 is unsealed, and the zinc-air battery 10 starts to react and is ready for use.

When the battery holding seal 1 is attached to the zinc-air battery 10 having the air intake 12 opened on its support surface 3, the zinc-air battery 10 is suspended as shown in FIG. 4 (a). 4 (b), the zinc-air battery 10 can be supported laterally, so that the zinc-air battery 10 can be installed at the battery mounting position of the device (hearing aid or the like) in any state. Can be moved and installed.

When the zinc-air battery 10 is an ultra-compact battery having a diameter of 6 mm or less, it cannot be freely handled with a fingertip.
Since it is possible to support the zinc-air battery 10 by holding it with a fingertip, it becomes easy to handle even the ultra-small zinc-air battery 10.

Since the zinc-air battery 10 is provided with a seal for sealing the air intake 12, the above-described effect can be obtained by extending the support surface 3 at one end of the seal. However, even in other ultra-small batteries, by attaching a sticker to any surface of the battery, the battery can be easily handled.

[0019]

As described above, according to the present invention, the work for mounting the microminiature battery at the mounting position can be facilitated by the battery holding seal having one end attached to the battery. The microminiature battery is not easy to handle with your fingertips, but the battery holding seal makes it easier to move the battery.
