The spacer 43 on the rear end side of the mechanical pencil refill 40 is a member for connecting refills having different inner diameters to the refill connection portions 21c and 31c having the same outer shape. 50 is formed to have substantially the same diameter as the rear end side inner diameter.
Therefore, the mechanical pencil refill 40 can be connected to the slide body 21 via the spacer 43, and the ballpoint pen refill 50 can be directly connected to the slide body 21.

  Next, the details of the refill identification members 100 and 100 ′ that are exchanged when the mechanical pencil refill 40 and the ballpoint pen refill 50 in the retractable writing instrument 1 configured as described above are replaced with replacement refills 40 ′ and 50 ′. Explained. The refill identification member denoted by reference numeral 100 ′ has the same configuration as that of the refill identification member 100 and has a different color, and thus a detailed description thereof is omitted.

The refill identification member 100 is formed so that it can be attached to any of the plurality of types of pressers 20 and 30 of the retractable writing instrument 1, and the replacement refills 40 ′ and 50 ′ that can be used for the retractable writing instrument 1. It is formed so as to be separably mounted.
More specifically, the refill identification member 100 is attached to the identification body 110 formed to be attached to the pushers 20 and 30 of the retractable writing instrument 1 and the replacement refills 40 ′ and 50 ′. And an auxiliary body 120 that is separably connected to the identification body 110 and is integrally formed by molding a synthetic resin material (see FIGS. 14 to 18).

The discriminator 110 is a member having the same configuration as the discriminators 24 and 32 described above, and has different colors or colors depending on the type (for example, ink color, core thickness, etc.) of the corresponding replacement refills 40 ′ and 50 ′. , Pattern, appearance shape.
Then, both side portions of the identification body 110 are connected to the auxiliary body 120.

  The auxiliary body 120 extends in a direction intersecting the two connection parts 121 and 121 connected to both sides of the identification body 110 and the connection direction of the connection parts 121 and 121 (vertical direction according to FIG. 14). The extension part 122 and the refill connection part 123 located on the opposite side of the extension part 122 with respect to the identification body 110 side are integrally provided (see FIGS. 14 to 18).

Each connecting portion 121 is a portion having a substantially conical shape with a thin tip side, and the tip portion is integrally connected to the side surface of the identification body 110 so as to be substantially orthogonal.
The two connection parts 121 and 121 are symmetrically provided so as to sandwich the identification body 110 from both sides.

  Further, these connection parts 121 and 121 are arranged in the vicinity of the connection protrusion 24b (or 32b) in the front-rear direction of the identification body 110 (see FIG. 17). According to this arrangement, it is possible to prevent the identification body 110 from rotating and dropping due to an impact during transportation or packing. That is, if the connection parts 121 and 121 are arranged at positions away from the connection protrusion 24b, the dimension between the connection parts 121 and 121 and the connection protrusion 24b becomes longer. The rotational moment of the identification body 110, which is the length of the arm, becomes relatively large, and there is a possibility that the connecting portion 121 may be easily separated unintentionally due to vibration or the like, but this embodiment prevents such a problem. be able to.

The extending portion 122 extends from the two connecting portions 121 so as to go rearward (rightward according to FIG. 14) along the axial direction of the retractable writing instrument 1. It is formed in a shape. The extending portion 122 acts as a runner that guides the molten resin to the identification body 110 and the refill connection portion 123 when the refill identification member 100 is resin-molded.
The extended portion 122 has a plurality of (three in the illustrated example) protrusions 122a, 122a, and 122b that protrude in the same direction as the connection protrusion 24b (32b) of the identification body 110 (FIGS. 15 to 17). reference).

The two protrusions 122a and 122a are arranged so as to be positioned on both sides of the identification body 110 (see FIG. 17). Further, the protrusion 122b is disposed closer to the refill connection portion 123 on a substantially center line between the two connection portions 122a and 122a.
These protrusions 122a, 122a, and 122b act as contact portions of protruding pins that protrude from the molding die by protruding the refill identification member 100 when the refill identification member 100 is resin-molded.
Further, the rear protrusion 122b is formed with a protrusion amount equivalent to the connection protrusion 24b (or 32b) of the identification body 110. According to this dimension setting, when the refill identification member 100 is placed or packaged, only the identification body 110 is pressed against another object (for example, a packing material) and extended. It is possible to prevent separation from the portion 122.

  In addition, the refill connection portion 123 is formed in a protruding shape that protrudes rearward (rightward according to FIG. 14) from the extending portion 122. The refill connection portion 123 is a convex curved protrusion 123a (FIG. 14) that expands in the width direction on the protruding end side so as to be fitted to the inner peripheral surface of the rear end opening of the replacement refills 40 ′ and 50 ′. And FIG. 17).

  And the refill identification member 100 of the said structure is detachably connected to the rear-end part of replacement | exchange refill 40 '(or 50'). In this connection state, the identification body 110, the extending portion 122, and the refill connection portion 123 constituting the refill identification member 100 are arranged in a substantially straight line on the axis of the replacement refill 40 ′ (or 50 ′). Is arranged (see FIG. 15).

One replacement refill 40 ′ is a mechanical pencil refill in which lead cores having different diameters can be used with respect to the mechanical pencil refill 40.
The other replacement refill 50 ′ is, for example, a ballpoint pen refill provided with ink having a different color from the ballpoint pen refill 50.

Next, the characteristic effects of the refill identification members 100 and 100 ′ having the above-described configuration will be described in detail.
As shown in FIGS. 3 and 4, the refill identification member 100 (or 100 ′) is detachably attached to the rear end portion of the replacement refill 40 ′ (or 50 ′), so that the replacement refill with the refill identification member is provided. Configure A (or B).

As shown in FIG. 3, when the replacement refill A with the refill identification member for the mechanical pencil is configured, the refill identification member 100 is connected to the replacement refill 40 ′ for the mechanical pencil via the spacer 43. The
Then, as shown in FIG. 5, the replacement refill A with the refill identification member is inserted into a cylindrical protective case a and stored in a packing bag or a packing box in this state.

  Further, as shown in FIG. 4, when the replacement refill B with the refill identification member for the ballpoint pen is configured, the refill identification member 100 'is directly connected to the replacement refill 50' for the ballpoint pen. The replacement refill B with the refill identification member is stored in a packaging bag or a packing box (not shown).

  Therefore, since the refill identification member 100 (or 100 ′) and the replacement refill 40 ′ (or 50 ′) are integrally handled, the identification object 110, which is a relatively small part, is used in the parts management stage and the sales stage. In addition to preventing loss, the operation of taking out the identification body 110 from a packaging bag or a packaging box can be easily performed.
