Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electromotive force consumption checker that displays the consumption of electromotive force of a dry battery.

[0002]

[Prior art]

 Conventionally, the electromotive force consumption checker, which measures the consumption of electromotive force, generates Joule heat in the conductive circuit by the current passed by the electromotive force, and causes the thermosensitive layer provided on the conductive circuit to develop or discolor. By doing so, the degree of consumption of electromotive force of dry batteries was measured. Such an electromotive force consumption checker has, for example, a sheet film shape as shown in FIGS. 5 (a) and 5 (b), as shown in JP-A-63-266374. When using this electromotive force consumption checker, the electromotive force consumption checker was bent, and the dry battery terminal crimping portion was crimped to each terminal of the dry battery to measure the consumption of electromotive force of the dry battery.

[0003]

[Problems to be solved by the device]

 However, in order to measure a single dry battery, the distance between the two dry battery terminal crimping parts (4) and (5) provided at both ends of the conductive circuit (3) must be at least 90 mm or more. Need. For this reason, if this spacing is attempted, the size and length of the electromotive force checker itself is larger or longer than the dry cell even if the conductive circuit is provided as a diagonal line as shown in FIG. 5 (b). In addition, when measuring dry cells of other sizes such as AA or AA with the above-mentioned electromotive force consumption checker, the electromotive force consumption checker itself must be broken. It was difficult to crimp the part to the positive and negative terminals of the dry battery, which made it very difficult to measure. On the other hand, the electromotive force consumption checker is often packaged together with the dry cell, and in that case, the size of the electromotive force consumption checker is larger and longer than the dry cell, so that both the dry cell and the electromotive force checker are packaged together. Was difficult to package and sell.

Further, since the conventional electromotive force consumption checker and the dry battery are separate components, they are often distributed and stored separately, and when the dry battery is in use, the electromotive force of the dry battery begins to disappear. When I felt it, I could not measure the power consumption of the electromotive force of the dry cell instantaneously because there was no electromotive power consumption level checker at hand or I could not find it.

The present invention has been made in order to solve the above-mentioned problems, and when it is desired to measure the degree of consumption of electromotive force of a dry battery, an electromotive force wear degree checker that can be immediately and easily measured on the spot. Is provided.

[0006]

[Means for Solving the Problems]

 The present invention provides a dry battery in which a conductive circuit is provided on a substrate film, a heat sensitive layer that develops or changes color by heat is provided on the conductive circuit, and the degree of consumption of electromotive force of the dry battery is measured by the color or discoloration of the heat sensitive layer. It is a sheet-like electromotive force consumption checker that can be wrapped around the conductive circuit. When the substrate film is unfolded by cutting this easy-to-cut line with a score line, the dry battery terminal crimping part of the electromotive force consumption checker is crimped to the terminals on both ends of the dry battery. It is a checker.

[0007]

[Action]

 Easily attach the substrate film so that the crimps of the dry battery terminals located at both ends of the conductive circuit of the electromotive force consumption checker wrapped around the dry battery are slightly larger than the length between the positive and negative terminals of the dry battery to be measured. Spread along the cutting line and crimp the battery terminal crimping parts located at both ends of the board film to each terminal of the dry battery, and measure the consumption of electromotive force of the dry battery.

A basic cross-sectional view of the checker, and FIG. 5 is a plan view of a conventional electromotive force consumption checker for dry batteries.

As shown in the cross-sectional view of FIG. 4, the electromotive force consumption checker of the dry battery basically has a conductive circuit (3) provided on the substrate film (1), and the conductive circuit (3) is provided on the conductive film (3). A heat sensitive layer (2) is provided. The substrate film (1) is made of a material which has good printability, has a large dielectric breakdown voltage, has a wide durable temperature range, has heat shrinkability, and is transparent. Polyethylene terephthalate (trade name: Bottle Mate L100: Diafoil Co., Ltd.) is used as the material of the substrate film (1) of this example, as well as polyvinyl alcohol, polypropylene, polyamide-based, and polyimide-based. Etc. can be used. The thickness of the substrate film (1) in this example is 40 μm. The optimum thickness of this substrate film (1) is between 20 and 100 μm. The conductive circuit (3) of this embodiment is formed by screen printing. The ink used in the conductive circuit (3) appropriately generates Joule heat generated by a steady current flowing in the conductive circuit (3). The ink used in this example is silver ink (trade name: DOTITE XA-498: Fujikura Kasei Co., Ltd.). In addition, carbon, aluminum, copper or the like can be used as a heat generating material for the conductive circuit (3). In addition, a polyester-based, acrylic-based, urethane-based resin or the like can be used as the medium. The thickness of the conductive circuit (3) in this embodiment is 5 to 6 μm. The optimum thickness of this conductive circuit (3) is between 2 and 20 μm. The heat-sensitive layer (2) of this example is formed by screen printing. The ink used in this example is a thermal ink (trade name: U13050: Sakura Palace Co., Ltd.). The thermal ink changes from black to transparent at about 50 ° C. With this discoloration, the degree of consumption of electromotive force of the dry battery can be measured. In addition, as the ink for the thermosensitive layer (2), thermochromic ink (trade name: Metamo Ink: Pilot Ink Co., Ltd.) can be used. The thickness of the heat sensitive layer (2) is 10 to 100 μm. The optimum thickness of this heat sensitive layer (2) is between 10 and 100 μm.

In this embodiment, as shown in FIG. 3, a printing layer (10) is provided on the substrate film (1) by offset printing. This printed layer (10) is not provided on the heat sensitive layer (2) in order not to prevent the color change of the heat sensitive layer (2) from being seen. By providing the print layer (10), it is possible to provide a print layer such as a pattern or a character for each dry cell. Moreover, the insulating layer (11) of the present embodiment is formed by screen printing. The ink used in this example is a white ink (trade name: EGM Conc: Teikoku Ink Co., Ltd.). The color of this ink may be any color other than black. The role of this insulating layer (11) is to prevent the conductive circuit (3) from directly contacting the dry battery (9), and also to have the dry battery terminal crimping parts (4) and (5) by the easy-to-cut line (7). This is to protect the conductive circuit (3) when raised.

The easy cut line (7) is made of any of a score line, a perforation line, and a half cut.

In the shape of the present invention, as shown in FIG. 1, the conductive circuit (3) is formed in a C-shape with four corners bent at right angles. The dry battery terminal crimping portions (5) and (4) are provided at both ends of the conductive circuit (3) with a gap therebetween. The heat-sensitive layer (2) is placed on the conductive circuit (3) on the conductive circuit (3) depending on the strength of the electromotive force of the dry battery to be measured, the length of the dry battery, and the state of the heat-sensitive ink used in the heat-sensitive layer (2). It is provided with a certain length at a portion equidistant from (5) and (4). Further, cut lines (6) are provided so as to surround the vicinity of the dry battery terminal crimping portions (5) and (4) provided at both ends of the conductive circuit (3). Two easy-to-cut lines (7) are provided on both sides of the conductive circuit (3) from the cut line (6).

In the method of use of the present embodiment, the sheet-like electromotive force checker formed by the above-described method is driven so that it fits the circumference and length of the dry cell such as AA battery and AA battery used. Be pulled out. Then, both ends of the punched electromotive force consumption checker are formed into a cylindrical shape with a size of a dry battery around which the electromotive force consumption checker is wrapped with a heat seal, a pressure-sensitive adhesive, a thermal adhesive or the like. Next, the electromotive force consumption checker is put on the dry battery in a cylindrical shape and heat-shrinked. Therefore, the dry battery and the electromotive force consumption checker can be sold and distributed together. Further, since the electromotive force consumption checker of the present invention is wrapped around the dry battery by heat contraction, it can be easily stored in the portion where the dry battery is stored when used. Also, if the sheet-shaped electromotive force consumption checker is made into a cylindrical shape, using a pressure-sensitive adhesive will require the electromotive force consumption checker even if the dry cells are sold and distributed separately. By attaching the electromotive force consumption checker accordingly, the electromotive force consumption checker is formed into a cylindrical shape, and the electromotive force consumption checker is covered with a dry battery to be used as described above. . When the electromotive force consumption checker is formed into a cylindrical shape as described above, the insulating layer (11) is placed inside so as to face the dry battery and the printing layer (10) is placed as shown in FIG. The print layer (10) for the design and characters is formed so that it can be seen from the outside so that it faces the outside.

The electromotive force consumption checker wound around the dry battery as described above has the dry battery terminal crimping parts (5) and (4) by the cut line (6) and the easy cut line (7). Tear on both sides along. Next, the dry battery terminal crimping parts (5) and (4) are crimped to the plus and minus dry battery terminals (8) of the dry battery (9) to measure the consumption of electromotive force of the dry battery (9).

[0015]

[Effects of the Invention] As described above, since the dry battery and the electromotive force consumption checker are integrated as in the electromotive force consumption checker according to the present invention, the electromotive force consumption checker can be used anytime, anywhere. When you want to measure the consumption of electromotive force of a dry cell, you can measure it immediately. In addition, since the electromotive force consumption checker is molded to the size of the dry battery, it is possible to save unnecessary parts economically even when it is used.

Further, since the heat sensitive layer is covered with the substrate film, the heat sensitive layer is not damaged by use. Even if there is no need to use the electromotive force checker because the electromotive force of the dry battery around which the electromotive force consumption checker is wound up disappears, you can use it to measure the consumption of another dry battery by removing the electromotive force consumption checker. You can use the electromotive force consumption checker as many times as you like.
