Description

  The present invention relates to an improvement of a portable power supply device that can supply power to various portable devices such as a mobile phone.

  As mobile phones (including so-called smartphones) become highly functional and multifunctional and use time increases, power consumption is increasing. For this reason, the battery pack attached to the mobile phone has a problem that the battery capacity is insufficient. On the other hand, a portable power supply device (mobile battery) capable of supplying power to various portable devices such as a mobile phone and a tablet (straight PC) without being limited by time and place is described in, for example, Patent Document 1 and the like. And is widely implemented. Such a portable power supply device includes a secondary battery such as a lithium ion battery, and a synthetic resin casing that houses the secondary battery therein. Of these, the secondary battery is charged in advance from a household power source or an output terminal (USB terminal) of a personal computer. And when the power supply capacity (discharge capacity) of the battery pack attached to the portable device decreases, the secondary battery supplies power to the portable device to charge the battery pack.

  Since the portable power supply device as described above has many opportunities to be seen by the public, images (such as photographs and pictures) are displayed (printed) on the outer surface of the casing to enhance fashionability (designability) and provide advertising functions. It is desirable to have it. In the present specification and claims, the image includes symbols, symbols, and characters. Examples of a method for printing an image on a synthetic resin include screen printing and pad printing. However, in the case of screen printing or pad printing, it is difficult to print high-definition images such as photographs. In contrast, if printing is performed using a hot stamp, it is possible to display a high-definition image, but it is necessary to print the image on a transfer foil by gravure printing or the like, which increases manufacturing costs. It is also possible to attach a seal (sticker) displaying an image, or to provide a hydrophilic ink receiving layer on the surface of the casing, and to print the image using aqueous ink on this ink receiving layer. There is a problem that it is low and easily deteriorates.

Utility Model Registration No. 3148046

  In view of the circumstances as described above, the present invention has been invented to realize a structure of a portable power supply apparatus that can display a high-definition image such as a photograph and can ensure the durability of the image.

The portable power supply device of the present invention includes a battery main body that can be charged and discharged, and a synthetic resin casing that houses the battery main body therein.
In particular, in the portable power supply device of the present invention, the surface to be printed which is a part of the outer surface (surface) of the casing is photographed with an ink containing a pigment, an ultraviolet curable resin, and a photopolymerization initiator. A target image such as a picture or a picture is printed. That is, the ink is sprayed (sprayed) for each color (pigment color) toward the printing surface, and ultraviolet light is irradiated to the sprayed ink to cure the UV curable resin (change the monomer into a polymer), and the pigment. Is fixed on the printing surface to print the target image.
When implementing such a portable power supply device of the present invention, specifically, for example, the ultraviolet curable resin is an acrylic resin.

When the present invention as described above is carried out, it is preferable that the printed surface is white and the pigment is white as in the invention described in claim 2. Specifically, the ink includes a so-called three primary colors cyan, magenta, and yellow, each containing a white pigment, and if necessary, a black pigment. The object image is printed using an object.

  Moreover, when implementing this invention, Preferably, the particle diameter of the particle | grains which comprise the said pigment shall be 100 nm or less like the invention described in Claim 4.

In the case of the portable power supply device of the present invention configured as described above, even when the target image is a high-definition image such as a photograph, the target image can be displayed vividly, and the durability of the image is further improved. Sex can be secured. As a result, the fashionability (designability) and the advertising function of the portable power supply device can be maintained in a good state over a long period of time.
Moreover, according to the invention described in claims 2 to 4, the white color contained in the target image can be vividly developed. Accordingly, the color of human skin can be vividly developed, and even when a photograph of a person is adopted as the target image, the target image can be displayed vividly.

The perspective view which shows one example of embodiment of this invention.

  FIG. 1 shows an example of an embodiment of the present invention. The feature of the portable power supply device of the present invention, including this example, is a structure for displaying a high-definition image such as a photograph and ensuring the durability of the image. The structure and operation of the other parts are basically the same as those of conventionally known portable power supply devices.

  The portable power supply device 1 of this example includes a battery body 2 and a casing 3. Among these, the battery body 2 includes a rechargeable secondary battery 4, an input terminal 5, an output terminal 6, a battery capacity display unit 7, and a battery capacity confirmation button 8. Of these, the secondary battery 4 is constituted by a lithium ion battery or the like, and the input terminal 5 is connected to a household power source or an output terminal {USB (Universal Serial Bus) port} of a personal computer by a cable (not shown). Charged by things. Further, the secondary battery 4 supplies power to the portable device by connecting the output terminal 6 to an input terminal of a portable device such as a mobile phone or a tablet with a cable (not shown), and a battery attached to the portable device. Charge the pack. The discharge capacity of such a secondary battery 4 is, for example, about 1000 to 10000 mAh. In this example, the input terminal 5 is a micro USB port (Micro-B), and the output terminal 6 is a USB port (Standard-A). However, the input terminal 5 and the output terminal 6 may have other shapes (another standard) such as an EIAJ port.

  The battery capacity display unit 7 is for displaying the battery capacity (discharge capacity) while the secondary battery 4 is being charged or while power is being supplied to the portable device. Consists of 3) LEDs. That is, the battery capacity display unit 7 switches the lighting states (continuous lighting, blinking, and extinguishing) of these LEDs according to the battery capacity of the secondary battery 4. In the case of this example, even when the secondary battery 4 is not being charged or when the portable device is not being charged, the secondary battery capacity is displayed by the battery capacity display unit 7 by pressing the battery capacity confirmation button 8. The battery capacity of the battery 4 can be confirmed. However, such a battery capacity confirmation button 8 may be omitted.

  The casing 3 is made of a synthetic resin such as ABS resin, polycarbonate (PC), polypropylene (PP), polyethylene (PE), or a mixture thereof, and is formed in a substantially rectangular box shape (substantially rectangular column shape). The battery body 2 is housed in the interior. In the case of this example, the color of the synthetic resin constituting the casing 3 is white. The size of the casing 3 is, for example, about 50 to 150 mm in width and height and about 5 to 20 mm in thickness. And the target image 10 which is a photograph, a picture, etc. is printed on the top plate part (printed surface) 9 of such a casing 3. The target image 10 is printed on the top plate portion 9 with an ink (ultraviolet curable ink) containing a pigment, an ultraviolet curable resin, and a photopolymerization initiator. Particularly in the case of this example, in addition to the ink containing pigments of the so-called three primary colors cyan, magenta, and yellow, the ink includes a white pigment, and further includes a black pigment. I am using something. The particles constituting the pigment contained in the ink are ultrafine particles having a small particle size. More specifically, a rice grain shape having a particle size of 100 nm or less and a relatively uniform shape is used.

  When printing the target image 10 on the top plate portion 9, first, ink is ejected (sprayed) for each color (color of pigment) toward the top plate portion 9. In the case of this example, for each color, a plurality of nozzles for ejecting ink are arranged in a straight line, and the casing 3 (portable power supply device 1), which is a printing medium, is passed under these nozzles. A line head type printing machine that sprays ink onto the top plate portion 9 of the casing 3 is used. Further, a printing program is set so that ink is not sprayed on the exposed portion of the LED constituting the battery capacity display portion 7 of the top plate portion 9. Next, the target image is obtained by irradiating the ink sprayed on the top plate portion 9 with ultraviolet rays to cure the ultraviolet curable resin (change the monomer into a polymer) and fixing the pigment on the top plate portion 9. 10 is displayed (printed) on the top plate portion 9. As such an ultraviolet curable resin, for example, an acrylic resin can be used.

  As described above, in the case of the portable power supply device 1 of this example, the casing 3 is made of ultraviolet curable ink that cures the ultraviolet curable resin contained in the ink and fixes the pigment by irradiating the ultraviolet rays. The target image 10 is printed on the top plate portion 9. Therefore, even when the target image 10 is a high-definition image such as a photograph, it can be displayed vividly. Also, durability (especially water resistance) is improved compared to the case where a sticker displaying an image is attached or a hydrophilic ink receiving layer is provided and an image is printed using water-based ink on the ink receiving layer. You can make it. As a result, the fashionability (designability) and the advertising function of the portable power supply device 1 can be maintained in a good state over a long period of time.

  In particular, in the case of this example, the synthetic resin constituting the casing 3 is white, and in addition to the ink containing three primary color pigments, the one containing white pigment is used. Further, since the particles constituting the pigment are ultrafine particles having a small particle diameter, it is possible to improve the transmittance by suppressing the scattering of visible light. As a result, the white color included in the target image 10 can be vividly developed. Therefore, the color of human skin can be vividly developed. For example, even when a photograph of a person is adopted as the target image 10, the target image 10 can be displayed vividly.

  Further, in the case of this example, a line head type printing machine is used in which a plurality of nozzles are arranged in a straight line, and under the nozzles, the casing 3 as a printing medium is passed and the ink is sprayed. An image 10 is printed on the top plate portion 9. Therefore, the surface of the target image 10 can be smoothed to give the target image 10 gloss.

In addition, when implementing this invention, the color of the synthetic resin which comprises a casing can also be made into colors other than white. In this case, it is preferable that the top plate portion of the casing is colored white by painting or the like on the top plate portion that is the printing surface of the target image.
Further, the casing is not limited to a substantially rectangular box shape, but may have other shapes such as a polygonal column shape such as a triangular column shape or a pentagonal column shape, or a substantially cylindrical shape. However, also in this case, the printing surface of the target image is a smooth flat surface.
