Description

  The present invention relates to a knock type multi-color pen, and more specifically, a plurality of pen cores of different colors are provided, and a desired pen core is protruded by selectively pushing down a core feeding knock-out that protrudes from a shaft cylinder. The present invention relates to a knock-type multicolor pen to be made.

  Knock-type multicolor pens that have multiple ballpoint pens of different colors and are used selectively are widely available. For example, two-color pens including black and red, and various combinations of knock-type multicolor pens including ballpoint pen cores of different colors such as blue, green, orange, and pink, or mechanical pencil cores are commercialized. Has been.

  In these knock-type multicolor pens, generally, a knock for selecting a ball-point pen of a desired color and operating it with a fingertip is provided so as to protrude from the upper side surface of the shaft cylinder. The knock is provided for each pen lead and has a color corresponding to the color of the pen lead. This knock is made of plastic, and when it is molded into the same color as the pen core, the color tends to be dark and dull, and is unlikely to be a bright clear color. Also, if this is colored and transparent, it will not be a beautiful color because it will mix with the knocking color on the opposite side.

JP 2000-233596 A Japanese Patent No. 4201292

  As described above, the knockout knockout in the conventional knock type multi-color pen, when formed into a color corresponding to the pencore, tends to be dark and dull, and cannot be a bright and clear color. It was. Therefore, an object of the present invention is to provide a knock-type multicolor pen that has a bright and clear color of the knock and can provide an interesting feeling and a high-class feeling not found in conventional ones.

  The device according to claim 1 for solving the above-mentioned problem is a multi-type type in which a plurality of pen wicks of different colors are provided, and a desired pen wick is obtained by selectively depressing a knock-out knock protruding from the shaft tube. A knock type multicolor pen, wherein the knock has a two-layer structure of a colored transparent outer piece located on the outer side and a white opaque inner piece located on the inner side.

  In one embodiment, the clip is further bilayered with a colored transparent outer piece located on the outside and a white opaque inner piece located on the inside.

  The outer piece and the inner piece can be integrally formed by a two-color molding machine, and the outer piece and the inner piece can be individually formed and joined together. Moreover, the uneven | corrugated | grooved part which mutually engages closely may be formed in each joint surface of the said outer side piece and the said inner side piece.

  The multicolor pen according to the present invention is as described above, and the knock is a two-layer structure of a colored transparent outer piece located on the outer side and a white opaque inner piece located on the inner side. There is no light transmission from the inner side to the outer piece, and the color of the outer piece appears as a clear and clear color without turbidity. Is effective.

It is a perspective view which shows the example of an external appearance of the knock type multicolor pen which concerns on this invention. It is a longitudinal cross-sectional view of the structural example of the knock in the knock type multicolor pen which concerns on this invention.

  A mode for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the appearance of a knock multicolor pen according to the present invention, and its basic configuration is not particularly different from that of a general knock multicolor pen. That is, a shaft cylinder 1 having a plurality of pen cores with different ink colors, a knock 3 slidably disposed in an elongated hole 2 formed in the upper end side surface of the shaft cylinder 1, and a clip 4 are provided. Composed.

  The knock type multicolor pen according to the present invention is characterized in that the knock 3 has a two-layer structure of a colored transparent outer piece 5 located on the outer side and a white opaque inner piece 6 located on the inner side (see FIG. 2). The outer piece 5 and the inner piece 6 can be integrally formed by a two-color molding machine, but the outer piece 5 and the inner piece 6 can be formed separately and joined together later. In the latter case, in order to easily and surely join the outer piece 5 and the inner piece 6, the concave and convex portions 7 and 8 that engage with each other are formed on the joining surfaces of the outer piece 5 and the inner piece 6. It is preferable. In this case, the outer piece 5 and the inner piece 6 can be joined only by close engagement of the concavo-convex portions 7 and 8, but an adhesive may be used if necessary.

  The outer piece 5 is made of a transparent resin having a color corresponding to the pen core to which the outer piece 5 is attached, and has a finger-hanging projection 5a as in a general case. Further, the inner piece 6 is made of a white opaque resin, and has a conical portion 6a for fitting the pen core to the end portion, and an operating protrusion for automatically returning or the like that protrudes inward, like a general one. 6b. The outer piece 5 is required for the number of colors of the pen core, but one kind of inner piece 6 is sufficient. The knock 3 is composed of the outer piece 5 and the inner piece 6 as described above, but the original function of knocking to feed out the core is not different from a general one.

  In one embodiment, not only the knock 3 but also the clip 4 has a two-layer structure of a colored transparent outer piece 5 located outside and a white opaque inner piece 6 located inside.

  The knock type multicolor pen according to the present invention is as described above, and the knock 3 has a two-layer structure of a colored transparent outer piece 5 located on the outer side and a white opaque inner piece 6 located on the inner side. Therefore, light transmission from the inner side to the colored transparent outer piece 5 is blocked by the inner piece 6, and the white inner piece 6 serves as a backing material for the outer piece 5, and the light color of the outer piece 5 Appears as a clear and clear color with no turbidity. Therefore, in the case of the knock-type multicolor pen according to the present invention, an interesting feeling and a high-class feeling not obtained by the conventional multicolor pen can be obtained.

  Although the invention has been described in some detail with respect to its most preferred embodiments, it is apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention. Accordingly, the invention is not limited to that particular embodiment, except as limited in the appended claims.
