Abstract

PURPOSE:To secure complete safety on battery handling by allowing the vessel surface of a small battery, etc., to contain a flavor offering an unpleasant taste which makes a baby want to vomit it when he puts it into his mouth, hereby forcing the baby to vomit out it without swallowing it. CONSTITUTION:In a flat small battery, a negative electrode cap 5 and a positive electrode cap 6 are provided with a corrosion resistant and electrically conductive layer 9 on its surface such that said caps are not dissolved due to acid in the stomach and alkali solution in the bowels in a human body. Further, a flavor offering an unpleasant taste which makes a baby want to vomit it when he puts it in his mouth is absorbed into a resin layer 10 after filling the porous resion layer 10 comprising butyl rubber, chlorinated rubber into a gap between an insulating packing 8 and the negative electrode cap 5. Hereby, it is possible to avoid any danger such as swallowing without relying on the identification by letters difficult to be read by the baby.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for disposing of small batteries to prevent them from being swallowed by children, for example, or to prevent them from being eluted by stomach acid or the like even if they are swallowed.

With the spread of small electronic game devices, such as game watches and electronic desktop calculators, as daily necessities, small batteries such as sealed button-type alkaline batteries with electrodes housed in flat containers are increasingly being used as power sources for them. It looks like this.

However, these devices are close to infants and young children, and the small batteries that power them are easy to remove from the devices, and their shape is convenient for infants to put in their mouths. There are many accidents where batteries are swallowed.

If these small batteries are swallowed and remain in the body for more than 24 hours, the battery container etc. will be gradually eluted by gastric acid or alkali in the intestines, and the alkali or tetrabutylammonium perchlorine propylene contained inside will be eluted. It is widely used as an amalgam to improve the performance of electrolytes such as carbonate, zinc or lithium negative saliva.
3- The electrolyte flows out through the porous backing, which is provided to release harmful substances such as mercury into the body, or to leak hydrogen gas that accumulates inside the body.
The stomach and intestines become corroded and perforated, which is extremely dangerous.
There have also been cases of death. Therefore, this must be removed as soon as possible, and in addition to surgical removal, there are also cases of magnet removal.

As mentioned above, it is dangerous if it remains in the stomach for more than 24 hours, but in the case of infants, it may be difficult to detect it verbally because it is difficult to tell, or because medical facilities are far away such as in mountain villages. There may be delays, and the work of confirming the swallowing position using X-rays is especially difficult for female infants.
If X-rays are irradiated for a long time, there is a possibility of damage caused by X-rays.

In order to avoid the risk of swallowing as described above, measures are taken such as attaching labels to the surface of batteries that indicate this, but these measures do not have the ability to distinguish from letters etc. These measures must be aimed at unspecified people, as they may have no effect on infants and young children.

Therefore, in this invention, since even infants who are 4 months old or older have already developed a sense of taste, this physiological characteristic is utilized to increase the degree of discrimination between taste and feces. Moreover, the system improves the degree of identification and takes safe ergonomic measures, rather than treating the mistakes that often occur in accidents as mistakes made by unspecified persons.

In other words, Table 1 below shows the permissible dosage based on the solid object extrusion period, weaning period, and standard body weight of infants and the adult ratio at that time. are less likely to be swallowed by the extrusion reaction, and 4 to 6 years old
After the weaning period, the risk of swallowing increases.

On the other hand, the sense of taste and smell is fully developed by the age of 4 to 5 months, so the identification method based on taste as in this invention is extremely effective.

- Old - Table 1 Solid object extrusion reaction period of infants, etc.Furthermore, in the present invention, small batteries such as those described above are protected from being eluted by gastric acid or alkaline liquid in the intestines even if they are swallowed. It is something to be processed.

This invention was completed from the above-mentioned viewpoints, and its gist is that when a small battery such as a button-type alkaline battery housed in a flat container is placed on the surface of the container, if an infant or child puts it in their mouth, they will not want to spit it out. It contains a flavoring agent that has an unpleasant taste, or provides a layer containing a flavoring agent.

6- In order to prevent further elution by stomach acid or alkaline liquid in the intestine if swallowed, a corrosion-resistant conductive layer is provided on the electrode surface that is easily eluted in the body, and the container is made of a metal that is easily eluted, such as steel. In some cases, at least that part is provided with a corrosion-resistant conductive layer, or at least that part is made of a corrosion-resistant conductive layer or a corrosion-resistant insulator, and other parts that require sealing are covered with a corrosion-resistant insulating cover. This is what I did.

In the first invention of the present application, in which a layer containing a flavoring agent is provided on the surface of a container, for example, a small battery can be designed without changing the conventional dimensions because the flavoring agent is simply applied to the surface of the container. can do.

The present invention will be explained below based on the illustrated embodiments.

Fig. 1 shows an example in which a flat battery container is mainly composed of conductive caps. The positive electrode mixture-7- agent layer constructed is shown.

Between the negative electrode l and the positive electrode mixture layer, an electrolytic solution holding layer 3 and a separator q made of an alkaline solution such as caustic soda or caustic potash are provided.

On the other hand, S is a negative electrode cap made of steel, for example, and the negative electrode cap S
In this embodiment, the central part is projected to form a head Sα, and the periphery thereof is bent downward to form a flange sh, and the negative electrode/electrolyte holding layer 3 is covered with a negative electrode cap S. .

Further, 6 is a positive electrode cap made of steel, for example, and in this embodiment, a side portion 6h is provided in an upright manner on the periphery of the bottom portion 6a, and the tip of the side portion 4bf) is bent inward to provide a flange portion 6C. Inside, from below, a positive electrode mixture layer, a separator t1, an electrolyte holding layer 3, and a negative ffi/ are housed.
The inner wall of the side portion 6h and the flange portion Ac is configured to cover a part of the side surface and top surface of the negative electrode cap.

An insulating backing g is provided in the gap 7 formed by the side part Ah, the inner wall of the flange part 6C, and the side and top surfaces of the negative electrode cap S.
This ensures insulation between the negative electrode l and the positive image mixture layer.

In the flat-shaped small battery constructed as described above, a corrosion-resistant conductive layer 9 is provided on the surface of the negative electrode cap and the positive electrode cap 6 so that they are not eluted into the body by stomach acid or alkaline intestinal fluid.

The corrosion-resistant conductive layer 9 may include a plating layer of a corrosion-resistant metal such as gold, titanium, or tantalum, a conductive paint layer such as Kagen paint, a carbon layer of plastic bond described below, a conductive resin layer, or a conductive rubber layer. By forming the cap S on the surface of the cap B, the structure is reduced.

Further, the gap between the insulating backing t and the purchase cap 3 is filled with a porous resin layer 10 made of a material such as butyl rubber or chloride rubber, and the flavorant is absorbed into the porous resin layer /θ.

Furthermore, the flavoring agent may be applied to a punch-shaped label attached to the periphery of the head portion α of the negative electrode cap 3 and impregnated into the label, or applied to the surface thereof.

FIG. 2 shows another embodiment, in which the negative electrode l is made of zinc amalgam on the flow side, and the positive electrode mixture layer is made of silver oxide, graphite, etc. Between the negative electrode and the positive electrode mixture layer, an electrolyte holding layer 3 and a separator are provided as in the embodiment shown in FIG.

On the other hand, in this embodiment, the negative electrode cap 3 has its periphery bent downward to form a flange sh, and a corrosion-resistant conductive layer /J is provided on the upper surface of the cap through a thin metal layer l/. The center of the l is made to protrude to form the head/2a.

Further, the positive electrode cap 6 has a rising side portion 6h at its periphery, and an acid-resistant conductive layer 13 is provided on the lower surface of the positive electrode cap 6 via a thin metal layer //, and the center of one conductive layer/3 is made to protrude. to form a head 13α.

Note that the thin metal layers // and // are omitted when the conductive layer is directly attached to the upper surface of the negative electrode cap 3 and the lower surface of the positive electrode cap B after the oxide film has been sufficiently removed by blasting, etc. can do.

10- Also, an insulating backing T is fitted into the gap formed between the inner wall of the side portion 6b of the positive electrode cap B and the side surface of the negative electrode cap S.

The flat-shaped small battery described above has many common parts in terms of structure compared to the battery shown in Figure 1, but the sides t and h of the positive electrode cap and the gap between the negative electrode character 130 are more airtight than those in Figure 1. Therefore, in this example, the conductive layers provided on the top and bottom of the battery,
, /3(l), the outer surfaces of the positive electrode cap 6, negative electrode cap 3, etc. are covered with a corrosion-resistant insulating layer /lI.

In addition, as the corrosion-resistant insulating layer llI, trifluorochlorinated ethylene, i-fluorinated ethylene, chlorinated polyether, FRP
, butyl rubber, chlorinated rubber, polyethylene, polypropylene/polystyrene, polyvinyl chloride, or other plastics, and this plastic may be used as the carbon-bonding plastic described above.

Further, in this embodiment, the flavorant may be applied to the surface of the insulating layer/4, or the surface may be made porous so that the flavorant can be absorbed.

Furthermore, if an infant swallows a flat-shaped small battery like the one described above, there is a risk of suffocation if it gets stuck in the throat, but to prevent this, the center of the battery in the embodiment shown in Figures 1 and 2 is made hollow. Just leave it there.

The flavoring agent used in this invention is an unpleasant flavoring agent that, when put into the mouth by an infant, causes the child to want to spit it out, and includes bitterness, bitterness, salty taste, etc. For example, tannin, senburi, Examples include organic substances such as bittern, oobaku, chili pepper, colombo powder, and caffeine, inorganic substances such as alum, magnesium chloride, sodium chloride, and potassium chloride, and tinctures such as bitter tincture, which is an alcoholic extract of senburi, and capsicum tincture. be able to.

If the flavoring agent content is 16 g or less, which is the adult dose per battery, based on the acceptable acid dosage for 3-month-olds shown in Table 1 above, there is a high possibility that it will be taken into the mouth. It is safe even if put into the mouth by infants after weaning.

Based on the above criteria, the upper limit of the content of the main flavoring agents is determined as follows.

When applying these flavoring agents to the battery surface,
These flavorants may be added to a water-soluble viscous liquid such as methyl, ethyl, cellulose, gum arabic, or starch and applied directly to the surface of the battery or label, preferably with a non-stick glue after drying. A flavoring agent having an unpleasant taste or its extracted components is added to a dispersion medium such as gum arabic, water or ethanol to form a solution or suspension.
After application and drying, it is easily redissolved by saliva to release the flavoring agent. 73- If a preservative is added to the water-soluble viscous liquid, it is possible to prevent the organic substances contained therein from deteriorating.

Furthermore, when an inorganic flavoring agent is selected, there is no risk of deterioration compared to an organic flavoring agent.

Further, when the porous resin layer is impregnated with a flavoring agent, the ethanol extract of the flavoring agent may be absorbed into the porous resin layer.

Furthermore, as a method of providing a flavoring agent to a battery, a hydrophilic flavoring agent may be covered with a porous non-hydrophilic film and this may be applied to the battery surface, or the flavoring agent may be placed in a gelatin capsule or the like. A plurality of these capsules may be covered with a porous non-hydrophilic film, and this may be applied to the surface of the battery.

Alternatively, the flavoring agent may be contained in microcapsules, made into a single powder, and added to the above-mentioned water-soluble viscous liquid to be applied to a label, etc. Alternatively, a corrosion-resistant insulating layer may be heated. It is made of a shrinkable resin, and a flavor S material is sandwiched between the insulating layer and the battery, and the shrinkage of the insulating layer by heating causes the insulation layer to close between the insulating layer and the battery. A flavoring agent may be added to the mixture.

In summary, according to the present invention, the surface of the small battery contains a flavoring agent that eliminates the unpleasant taste, so if an infant or child puts it in their mouth, they can spit it out without swallowing it, and in case of any - Because the device is treated to prevent electrodes from being eluted even when swallowed, the harmful substances inside will not be discharged into the body. Complete safety measures can be taken.
