Definitions
- the present invention relates to a writing instrument and a method for disposing sealing means in the writing instrument. More specifically, the present invention relates to a writing instrument such as a batting type or a direct liquid type marker, and the sealing means is provided on a shaft containing batting or ink. The present invention relates to a writing instrument provided with a core holder and / or a tail plug to be fitted through, and an arrangement method of the sealing means in this kind of writing instrument.
- Writing instruments such as markers are roughly classified into a batting type in which batting with ink impregnated in the shaft is loaded and a direct liquid type (raw ink type) in which ink is directly injected into the shaft.
- the core is held by the core holder provided at the end of the shaft so that the outer end protrudes from the core holder by an appropriate amount, and the inner end is directly buried in the batting, Or it arrange
- the core holder may be formed integrally with the shaft in advance, or may be formed separately and then fitted to the end of the shaft. In the latter case, a flange is typically formed at the intermediate portion. The lower part of the lever flange is fitted into the shaft. And in order to seal the fitting part, O-rings, such as a silicone resin, may be fitted by the part. This O-ring fitting operation is performed manually, and is first performed by fitting the O-ring to the lower end of the shaft holder in the core holder and then moving it up toward the flange. .
- the O-ring as the sealing means is often used in the case of a deformed shape such as a rounded rectangular shape in which the section of the shaft and the core holder is not a perfect circle, but the O-ring in such a deformed shape is often used.
- the fitting work is particularly troublesome.
- the O-ring fitting work to the shaft holder of the lead holder and the tail plug is performed manually, and the work is time-consuming and requires improvement. It was done.
- the present invention has been made to meet such a demand, and it is possible to automatically assemble a means for sealing between the shaft, the core holder, and the shaft fitting portion of the tail plug without manual operation. It is an object of the present invention to provide a writing instrument that can be efficiently performed, and thus can greatly improve the assembly efficiency of the writing instrument, and a method for disposing sealing means in the writing instrument.
- the invention according to claim 1 for solving the above-mentioned problem is a writing instrument comprising a core holder and / or a tail plug fitted to a shaft containing batting or ink via a sealing means, wherein the sealing means Is a ring-shaped seal formed by secondary molding on the shaft inner fitting portion of the core holder and the tail plug that are primarily molded by a double mold method.
- a strip-shaped gate is provided so as to surround the shaft holder and the peripheral surface of the tail fitting portion of the tail plug in succession to the ring-shaped seal, and the core holder and the tail plug.
- a concave portion for accommodating the ring-shaped seal and the belt-like gate is provided around the shaft fitting portion.
- the sealing means is arranged in a writing instrument having a core holder and / or a tail plug that is fitted to the shaft containing the batting or ink through the sealing means.
- the seal is formed by secondary molding so as to surround the shaft fitting portion of the core holder and the tail plug after the core holder and the tail plug are first molded using a double mold method. A ring-shaped seal as a means is formed.
- a belt-like gate is provided so as to surround the peripheral surface of the shaft fitting portion of the core holder and the tail plug continuously to the ring-shaped seal, and the core holder and the tail plug A recessed portion for accommodating the ring-shaped seal and the belt-shaped gate is provided on the peripheral surface of the shaft fitting portion.
- the present invention is as described above, and the sealing means between the core holder and the tail plug and the shaft is formed by secondary molding after primary molding of the core holder and tail plug by the double molding method without manual operation. This eliminates the need for troublesome and time-consuming fitting work of sealing means such as an O-ring, and thus has the effect of greatly improving the assembly efficiency of the writing instrument.
- the sealing means disposing method in the writing instrument according to the present invention is a disposing method of the sealing means in the writing instrument comprising a core holder and / or a tail plug fitted to the shaft containing the batting or ink via the sealing means. Then, the ring as the sealing means is formed by secondary molding so as to surround the shaft fitting portion of the core holder and the tail plug after first molding the core holder and the tail plug using a double mold method.
- the writing instrument according to the present invention is manufactured by using the method.
- the writing instrument according to the present invention is a writing instrument provided with a core holder 3 and / or a tail plug 11 that is fitted to a shaft 1 containing batting or ink via a sealing means, and includes a core 4 at both ends of the shaft 1.
- FIG. 1 is a front view showing an external appearance example of the type a) of the above types, and shows a state where the cap 2 is removed from the shaft 1.
- a core holder 3 holding the core 4 is fitted to both ends of the shaft 1 through sealing means described later.
- a batting 5 (or raw ink) impregnated with ink is incorporated in the shaft 1, and the inner end of the wick 4 held by the wick holder 3 faces the wadding 5. Placed in.
- the core holder 3 includes a flange 6 at an intermediate portion thereof, and a portion below the flange 6, that is, an in-shaft fitting portion 7 is fitted into the shaft 1.
- the core holder 2 is pushed into the shaft 1 until the flange 6 hits the opening end surface of the shaft 1, so that the entire shaft fitting portion 7 is accommodated in one end portion of the shaft 1.
- the in-shaft fitting portion 7 is fitted into the shaft 1 through a sealing means, but the sealing means in the present invention is not an O-ring as in the prior art, but a ring formed by secondary molding by a double mold method. This is a shape seal 8. Below, the arrangement
- the double mold method used in the present invention is also called a two-color molding method, and is a method in which two types of resin are heat-sealed with a single molding machine, and there is no variation in molding cycle and stable product quality is obtained. It has the advantage that.
- the core holder 3 is first molded first, and then, as a sealing means, the ring-shaped seal 8 is formed by secondary molding so as to surround the lower portion of the flange 6 of the core holder 3.
- the A gate for guiding the molten resin to the cavity for forming the ring-shaped seal 8 in the mold is a band-shaped gate 9 formed in a band shape so as to surround the core holder 3 below the ring-shaped seal 8.
- the belt-like gate 9 portion can also perform a sealing function between the shaft 1 and the in-shaft fitting portion 7 of the core holder 3.
- a recessed portion 10 for accommodating the ring-shaped seal 8 and the strip-shaped gate 9 is provided on the peripheral surface of the core holder 3 (see FIGS. 2 and 3).
- the shaft 1 fits in the shaft fitting portion 7 of the core holder 3 without being stably displaced.
- the dress is smooth.
- the sealing means between the in-shaft fitting portion 7 of the core holder 3 and the inner surface of the shaft 1 is not manually operated, but by the double mold method, that is, the core. Since the holder 3 is automatically formed by the secondary molding after the primary molding, there is no need for cumbersome and cumbersome assembling work of the sealing means such as an O-ring, thereby greatly improving the assembling efficiency of the writing instrument. .
- This method is particularly suitable for the case where the core holder 3 has various shapes other than the cylindrical shape.
- FIG. 4 shows an example of the configuration.
- the tail plug 11 is primary-molded using the double mold method as described above, it is sealed by secondary molding so as to surround the shaft fitting portion 12 of the tail plug 11.
- a ring-shaped seal 13 is formed as a means.
- a belt-like gate 14 is provided so as to continuously surround the ring-shaped seal 13 and surround the circumferential surface of the in-shaft fitting portion 12. Moreover, in that case, the recessed part 15 which accommodates the strip
